How about fasteners? What is the use of the fastener?

With the growing social and economic growth, people’s living standards are also rising, the quality of life is getting better and better, when buying anything, more will be placed on the quality of the product. Especially for fasteners, they pay more attention to the quality of products. So there are more and more products we buy, so you may have a problem, that is to accumulate a lot of fasteners, such as a variety of manufacturing materials, they may come from machinery, construction and other fields, and many of the sources of fastener acquiring company in the market come from this. Many of these things may not be reconciled when garbage is thrown away, but what can they do?

First, if we are happy to use these materials for other uses, we will be able to do so. A flat bar is a good material. In fact, the source of this material is mainly made up of carbon steel, which can be used as a good link material in other places, which is a fun and saving resource, and we can find a lot of flat – key gadgets on the Internet.
Second, if our family machinery has problems, they are good alternatives. We can do some simple repairs ourselves. When our home machinery problems need to be replaced, we can replace them directly to avoid the trouble of finding someone to repair it.

Process method of drawing pulley for aluminum workpiece

Wire drawing process for grinding wire drawing wheel refers to machining straight lines on the surface of parts by means of machine friction. Aesthetics has no standard and is very subjective. The utility model has the dual functions of removing the scratch on the surface of the parts and decorating the surface of the parts. Straight wire drawing process has two kinds: continuous filament and interrupted yarn. The continuous thread can be obtained by a continuous horizontal linear friction on the surface of the part (such as hand grind under the condition of the present device or the brush of a steel wire with a planer in the condition of a present device). Changing the diameter of the stainless steel brush can get different grain sizes. Interrupted silk pattern is usually made on brushing machine or rubbing machine. Production principle: two groups of rotating differential wheels are used, the upper group is a fast rotating grinding roller, the lower group is a slow rotating roll, and the aluminum or aluminum alloy plate passes through the two groups of roller wheels and is brushed out with fine and intermittent straight lines.

Before bending and so on, the drawing wheel is generally a flat drawing process which has a high requirement for the front treatment of the base material, otherwise it will amplify the defect of the base material after the appearance is disposed. At present, there is no evaluation method and standard for drawing aesthetics in the industry, and some customers use roughness measurement to judge.

Now, the appearance of aluminum alloy products is not electroplating, some customers use the microscope to enlarge the observation of drawing process effect. The drawing wheel can only be used as an auxiliary means. After all, the drawing process is a macroscopic overall effect, not the micro effect. It’s a variety of colors that are oxidized. Anodizing has heard that Han Tong lapping against aluminum materials is mainly to strengthen its surface hardness (a layer of ceramic) to enhance its friction resistance. Hot stamping is also a kind of heat transfer. Die casting aluminum parts can be treated by wire drawing process, and then a layer of protective film is sprayed to prevent oxidation. The die casting, of course, can also be treated with surface oxidation. The appearance of a dumb light can be done, but the effect of the grinding is a prophase process of oxidation disposal through the sand blasting process.

What should we do and how can we achieve network marketing?

The most fundamental problems in operation should be: flow, dynamic sales (transformation), cost and profit.
The most fundamental is: market industry, customers, competitors.
First flow: where is the customer? How can we let customers know that we have good quality and inexpensive products? The initial flow is very important.
Second move pin: will customers buy when customers come? How much will they buy and how much is the unit price? Can the high conversion rate be formed?
Third cost: how much cost will we pay from the purchase of goods to the end of the consumer? There is no way we can try to reduce the cost as much as possible.
Since you are going to go to the operation in the future, I need to remind you here that you must not be smart enough to reduce costs, that is to say, low cost does not mean the low quality of the goods.
Fourth profit: This is the ultimate goal of the business, hard for a while, how many of our profits, it is Lei Feng or Ma Yun to work, the heart must have a bottom. It is necessary to point out that, in the current state, there are too many electric businesses to learn Lei Feng. After you go to work, especially in practice, we must pay attention to the cost control and maximize the profit.
The practice of practice
The above talks about some basic points of operation, and we all know something about it. In the end, how can we improve our operational skills by doing business?
1. Insist on learning.
Ma Yun knows everything about Taobao. It seems that Ma Yun is a God. But you see, God loves learning. However, what people learn is different from ours. They visited Li and Wang Lin, a qigong master. The realm is different. After all, the level is there. But we are different. We are too far away, so we can only learn to improve our vocational skills through learning from the people around us and learning from the Internet.
There is a saying: because the long ones are not high enough, they can only tread the past under their feet. In other words, we should continue to learn and accumulate.
Two, more practice and more summary.
As long as you do e-commerce, you will have a lot of things to do every day. The title should be optimized and the poster is made. It is a discount and a suitable discount tool. By the way, look at what performance of your products are in the search, and see what is worth learning by the competitors, especially the competition. Therefore, you are sure to be very busy, busy, have experience, know how to choose the selection, know what the main product should use, and know what should be paid attention to when the title is optimized. All you need is practice, but light practice is not enough. You want to think that operation is not a person to do, but a team is doing, even if you open a small shop, do you also need to sum up, see which do well, which is not enough, especially when the team, there is a summary, there is a summary. It will let the team take a lot less curve.
The fastest way for a person to grow is to sum up and think, and to think in practice.

Mold forming steps needed to be known to the mold

The mold is mainly composed of three parts: gating system, forming parts and structural parts. The specifications and uses of the mold are different, and there are many methods for molding the mold, including injection molding, compression molding, extrusion molding, press injection molding and hollow molding. Now let’s learn about the ten steps of mold forming.
1. when the molding tool is used, the CNC punch press is strictly prohibited from sheet stamping and can not be made empty. At the same time, it is necessary to check the tightness of the locking screw, otherwise it will cause the damage of the CNC punch press and the molding die easily.
2. the forming direction of the forming die should be chosen to form upwards so as to avoid the collision between the shape after forming and the steel ball on the worktable resulting in the deformation of the product.
3. the closed height and stamping stroke of each CNC punch press are different, so each mold must be adjusted to the shortest when used for the first time. At the same time, it should not be used directly on another punch. It needs to be reused after a high degree of fine tuning to avoid damage to the machine tool and mould.
The lower die of the 4. up mold is usually higher than the standard mold, so the punching die next to the mold is not used as much as possible to avoid the indentation of the plate. When the molding die is not used, please remove the oil from the machine tool and store the mould cabinet, so as to prevent the rust and dust from the die damage.
5. the full molding of mold needs to be adjusted by micro distance. The operator must be patient and careful in this process. The way of fine tuning is:
The punch stroke of A. CNC punching machine can not be adjusted, and it can only adjust the height of the mold blow head assembly.
The punching stroke of B. CNC punching machine can be adjusted. Only when programming, can the machine parameters be modified to meet the requirements.
C. adjust the height of the mold blow head assembly when the distance is adjusted.
6. for high forming or unconventional moulds, please do a good job of double side lubrication of the plate to strengthen the flow of the plate in the molding and reduce the chance of the plate breaking.
7. in the process of molding, the programming must be used by the molding process program, the sufficient discharging time is reserved when programming, and the speed of the punching machine is put to the slowest, low speed impact, so that the material after the molding is separated from the mold enough to avoid the deviation of the sheet deformation and the forming position.
8. the position of sheet metal forming is far away from the clamp and punching parts. The forming of sheet metal is finished as far as possible in the stamping process.
9. the use of other molds around the high molding dies, or the continuous processing of standard punching dies will cause deformation of the sheet metal.
10. the high molding die has the phenomenon that the plate has scratches and collisions, and the auxiliary transition of the lower die on the two sides of the mold can avoid this problem.
Hubei Sheng has been concentrating on the technical innovation and product development of all kinds of precision mold parts, automation equipment parts and parts. The experience of the industry has been accumulated, and the core technology of the research and development, design and manufacturing of the parts and parts of the precision mold and automation equipment has been successfully mastered.

30 principles of standardized production of injection moulds

1. less than 2020 of the mold embryo, between a and B boards need to be a pry pit; more than 2020 of the mold embryo, all templates including the thimble boards should be prized.
2 the mold guide sleeve should process the exhaust slot to prevent the guide pin from pulling.
3 die must not have sharp angle, need chamfering treatment. Excepted places are excepted
4 internal mold and mold parts shall not be welded without consent.
5 the periphery of the mold must be opened in the proper position. The specifications of the exhaust manifold refer to the die design manual.
6 as far as possible, avoid using the grinding machine to polish the mold. If you must use the grinding machine, you must use the oil stone (especially the parting surface).
7 the surface treatment of the inner surface of the die must be carried out according to the technical requirements of the BOM form or other official notification. Processing lines on non adhesive surfaces (wire cutting, milling machines, CNC Gong beds, spark machines) also need to be brightly lit.
8 all internal mold materials, mold grading requirements must be purchased according to the order, or the technical requirements formally identified in the design process. Material proof must be provided. If it is a hard mold, heat treatment report must be provided. All relevant certificates.
9 the front and back mould, insert, row position, oblique top, straight top (push block), shovel chicken, etc. need to process a waist round pit at the bottom or side, and engraved the name and hardness of the material.
10 row bits, pushing blocks, shoveling chickens and mouths and other important wear parts must be nitrided and hardened.
The 11 line must have a position. The positioning methods include catapult, wave beads, HASCO (DME) standard position clamp and so on. The row needs to have a pressure strip and a wear-resistant plate. Layering, wear resistant plate must be wear resistant hard material, need to add oil groove.
The 12 row inclined pillar must be tightly pressed, unable to rotate and loose. The tail part of the inclined guide must be processed into hemispherical or conical shape, which is beneficial to ensure normal movement of the row. The length, size and inclination of the slanting guide column must be the same for two or two more inclined columns on the same row.
13 cable-stayed seats must be hardened and hardened. The slanted roof must be processed with an oil tank, and the top seat is usually hardened to hrc40-45 by 2510 or Cr12, because the slanted roof is subjected to the impact load, so it can’t be too hard or it will break, and angle c angle at all right angles. There needs to be a skew guide plate (bronze). No welding.
The 14 channel and the injection position need to save the light #400-600.
15 the thimble, the barrel, the thimble, the oblique top and the thimble plate should be engraved with the corresponding identification code, which is convenient for installation. If the thimble position is not horizontal, the pin seat should be made into a “D” type or an anti pin key.
16 the thimble should adopt HASCO or DME standard, which kind of mould technology requirement determined by BOM table or other formal notice should be chosen.
17 processing water rubber ring (“O” ring) slot, the need for single side reserved 0.25mm clearance, the general rubber ring to prepress the 0.5-0.8mm. if not attached to this point, the apron is easy to be damaged by pressure, causing leakage.
18 nozzles to nitride, need to do stop pin. The radius of the pump must be in accordance with the requirements of the drawing. The nozzle is not nitrided, and it may have been damaged before the mold is moved.
19 conventional structure die must be equipped with supporting head, both ends need to be smoothed, small die prepressing 0.1mm, large die prepressing 0.1mm-0.15mm.
20 the diameter of the locating ring must conform to the drawing, and the form and position of the top bar must conform to the drawing.
21 according to the BOM gauge or the confirmed die diagram, the nozzle must be processed and installed according to the mold drawing. The drilling must not be drilled, and the sharp angle needs to be chamfered.
22 water must be in1, out1, in2, out2… ..
23 all the marks on the mould must be neat, straight and not crooked.
24 mold needs to be installed in the four sides of the side lock (straight lock). If you can not install the side lock, you need to install taper lock or conical lock. The taper lock should be installed horizontally.
25 all screws and mold fittings are required to have standard parts, and screw heads can not be sawn off. The length of effective locking of screws must be sufficient, normally 1.5 or 2.
26 the heat sink must have fillet to avoid scratching wires.
27 the hot mouth ID card is mounted on the side of the mold panel.
28 mold transfer inspection: need to cooperate with the mold engineer according to the “mold check list” acceptance before passing the packaging mold.
29 before moving the mold, it is necessary to carry out the test of water pressure (100Pa or above).
30 the outer surface of mould must be maintained in the manufacturing process to prevent rusting and scratching. Before the mold packing, white or / or colourless rust inhibitor is needed for the internal mold, all the surface of the mold must be cleaned, and then butter.
