Cause and solution of metal mould pulling injury

There are two main reasons for strain during workpiece forming:

One is that the mechanical wear is formed on the surface of the workpiece and the surface of the die convex and concave die because of the macroscopic mechanical concave or uneven surface of the die convex or die surface or the inclusion of other hard particles between the forming material and the die convex surface and the die surface. The solution is to carefully grind the surface of the die convex and concave die and strengthen the production. The management of the environment.

Two is caused by the wear of the surface of the workpiece and the surface of the die convex and concave die. It is also the most common and difficult situation in production. The following detailed analysis of the formation of adhesive wear and some basic measures to reduce the adhesion wear. In order to solve the problem of strain in the forming process of mould and workpiece, the basic principle of reducing adhesive wear should be reduced, and the nature of contact pairs should be changed as the starting point.

The following three pairs of contact pairs are formed, namely, the raw material, the workpiece and the mold, and the mold.

1. through the surface treatment of raw materials, such as phosphating, spraying or other surface treatment of raw materials, forming a layer of non metal film on the surface of the formed material, it can greatly reduce or eliminate the scratch of the workpiece. This method often costs higher, and needs to add additional production equipment and increase production process. This method sometimes has some effect, but it is seldom applied in practical production.

2. adding a layer of PVC film between mold and forming material can sometimes solve the problem of workpiece pulling. For the production line, the continuous supply film can be achieved through the mechanism, and for the stamping equipment produced in the periodic production, each piece of production must be added a thin film to affect the production efficiency. The general cost of this method is very high, and a large amount of waste will be produced. It is advisable to adopt this method for the production of small large pieces of large pieces. In some occasions where the forming load is very small, sometimes the problem of pulling the workpiece can be solved by adding lubricating oil or adding EP (extreme pressure) additive lubricant.

3. by changing the die convex, die material or the surface treatment of the die convex and concave die, the formed material is changed with the convex and concave die. Practice has shown that this is an economical and effective way to solve the problem of pull injury, and is widely adopted at present.

(1) the hard alloy can be used to solve the problem of scratch of the workpiece from the die convex and die material. In general, the convex and concave die made of this material is very high in tensile resistance, and the problem is that the material cost is high and it is difficult to process. For the larger mold, it is difficult to burn the large hard alloy block. Even if firing is successful, there may be cracks in the process, and the yield is low, and some of them are almost difficult to form. In addition, the cemented carbide is brittle, and must be extremely careful in the process of handling, installation and use. In addition, because the structure of the hard alloy is composed of hard tungsten carbide particles and soft bonding phase cobalt, hard tungsten carbide particles have high wear resistance and bite resistance, while cobalt phase is low in hardness and poor in wear resistance. The cobalt phase will be worn first in the process of use, making the surface of convex and concave die uneven, so that the surface of the concave die is uneven. The surface of the workpiece will also show a tensile mark. At this time, the surface of the die and die should be polished and polished before being reproduced. The use of a suitable copper based alloy can also solve the problem of the work of the workpiece, but the hardness of the copper base alloy is low, and the wear and tear is easy to appear. In the case of mass production, the cost of the material is low. For the larger mold, such as the forming die of the automobile panel, the alloy cast iron is used in large quantities. The cast iron can only reduce the strain of the workpiece and can not eliminate the problem of drawing. However, the mould made by this way is usually short in life. After a period of time, if there is a strain, it is necessary to repair the mold and re treat the surface.

(2) it is an economical and effective way to solve the problem of scratch on the surface of the workpiece by the surface treatment of the die, especially the surface super hardening treatment of the die convex and concave die. There are many kinds of surface treatment methods, such as hard chromium plating, electroless nickel phosphorus, special alloy of brush plating and so on. Chemical heat treatment has various kinds of nitriding, boriding, sulphur and so on; surface super hardening treatment includes chemical vapor deposition (CVD), physical vapor deposition (VVD), physical and chemical vapor deposition (PvD), “ID”. Coating treatment. Electroplating, electroless plating and brush plating are different ways to form alloy coating on the surface of workpiece by electrochemical or chemical reaction. The properties of the alloy coating are different. As for wear resistance and occlusal use, hard chromium plating, electroless Ni-P plating and nickel tungsten alloy plating are widely used. These methods can sometimes achieve certain results for smaller forming load or larger die. The problem of such surface treatment is that on the one hand, the hardness of the surface hardened layer is low, and it is easy to wear. On the other hand, the coating is mechanically combined with the matrix material. In the case of large load, sometimes the coating will be flake with a few times, and the effect will be lost once the coating is peeled off. Chemical heat treatment is to heat and heat the workpiece in a medium containing some or some chemical elements. Through the physical and chemical effects of the workpiece and the medium, these or these elements are infiltrated into the surface of the workpiece, and then the appropriate square is used.

Basic knowledge of hardware fasteners

Hardware buckle is a generic term for the hardware industry. It refers to various metal buckles, which involves a wide range of fields, including bags, clothing, shoe materials, leather goods, etc. such as hardware belt buckles, hardware buckles, hardware pin buckles, hardware buckles, hardware buckle, hardware D buckle, hardware buttons, hardware buttons, hardware pair buckles. Hardware round buckle and so on.
2 classification

The quality assurance of parts has always been a matter of great importance to mechanical processing enterprises. But in the actual production, there are some problems in the process of stamping, and the following drawing oil manufacturers “chemical” to sum up, let everyone in the future production can be used for reference.

1. The twisting of the metal stamping parts
Stamping parts in progressive die, by punching cut around the expected method to form stamping parts. The overturn of stamping parts is mainly due to the tensile strength of the material on the die surface. Therefore, the stamping and stretching oil factory “chemical” proposal when pressing, pressing and compressing material is the key to prevent the stamping material from turning and twisting. Causes and Countermeasures of stamping and twisting during stamping.
The stamping and distortion of punching parts resulted in poor forming after bending, which needs to be solved from blanking blanking station. This is mainly due to the fact that the stamping parts are not stable enough, so the way to solve the problem is to guide the guide position and bend in the bending process before bending, and to press the material to prevent the sliding movement of the stamping parts from bending in the bending process.

Two. The tearing of the metal stamping parts
According to the actual production situation, through the inspection of the tear part, the fracture shape and the degree of extrusion, the “chemical” of the punching and drawing oil manufacturer is found to cause the tear and the skew to be mainly reflected in the flanging forming process. Therefore, this process needs to be paid attention to, so the main reasons for this process are as follows:
1. The forming process parameters are not in place
In the forming process of the workpiece, the process requires that the die, the material core and the two must be closely combined, and the plastic deformation of the sheet is formed when the slide block of the machine is slid. However, in the process of pressing, the quality of the parts is unstable, the main reason is that the processing technicians have not adjusted the pressure of the machine tools at this stage, resulting in the problems of stability and the instability of the quality of the parts.
2. Defects in the design of flanged forming die
The mold for the first mock exam double cavity, because this process in addition to the content of flanging, with shape, with special complex curved surface parts, narrow, forming requirements of die material core and forming surface character, resulting in the mold structure forming conditions to form large, small volume of binder. The “chemical” of the punching and drawing oil manufacturer thinks that this is mainly due to the fact that when the personnel are involved in the original mold design, only the small pressure surface is considered to be small, and the forming of the core forming is ignored.

Three. Measures for improvement
1. Select suitable high quality stamping oil
In stamping and drawing processing, stamping and drawing oil is a necessary auxiliary product. Through the analysis of the well-known stamping and drawing oil factory chemical industry, it is found that the factors that affect the rate of stamping and drawing are roughly the precision of the stamping equipment, the level of the operator, the performance of the material, the rationality of the mold design, the condition of the stamping die and the quality of the stamping die. The factors that affect the yield of stamping and drawing are very complicated, and stamping and drawing oil is also one of the important factors that affect the success or failure. The special purpose of stamping stretch oil is very strong, and the application scope is narrow. Therefore, when selecting the stamping stretch oil, we must carefully investigate the following aspects. Stamping and drawing process: blanking, drawing, drawing thinning and bending. The material of the workpiece is aluminum, copper, alloy and silicon steel sheet. (3) deep drawing coefficient and deep drawing times. 4. The tonnage and working speed of the punching drawing machine, and the shape of the workpiece.

Key points for the installation of bathrooms

The hinge of bathroom hinge is exquisite. 6 important points to note are:

(1) before the installation of the bathroom hinge, check whether the hinge and window frames and fans match.

(2) check whether the hinge and the hinge are high, wide and thick.

(3) bathroom hinge installation should check hinge and its connection screws, fasteners are supporting.

(4) the connection of hinges should be matched with the material of the frame and fan, such as the hinges used in the steel frame and wooden doors, welding on the side of the steel frame, and the wooden screw attached to the side of the door fan.

(5) when the two sheets of the page are asymmetrical, it should be identified which one should be connected with the fan, which should be connected with the door and window frame, and one side attached to the three section of the axis should be fixed with the frame, and one side attached to the two section of the axis should be fixed with the frame.

(6) when the bathroom hinge is installed, the hinge shaft on the same fan should be kept on the same plumb line, so as to prevent the doors and windows from projectile.

Which material is good for bathroom hooks, stainless steel hooks and brass hooks?

1, copper copper hook electroplating chromium color, if it is enough, it is longer than stainless steel hook durable and bright, appear noble, but the price is not very expensive, generally in the 250~1200 yuan. But many manufacturers are electroplating decorative chromium, so the product has the possibility of coating desalting, plus the coating is not enough thick sealing enough, will make copper volatile copper green, if you want to choose copper must choose the well-known manufacturer’s products.
2, stainless steel hook also has defects, if it is to use 201.202 of the material production is easy to rust, but the price is cheap 30~60 yuan, if the use of 304 to do a lot of effect, if good polishing and electrolytic treatment, and then durable and beautiful, price between 60~200 yuan (because of the problem of thick and thin material). There are A3 products re plating products 3 years after all rust, and space aluminum is also easy to grow powder, and hardness is not enough, so you have to choose good, see the material. Choose the product to see your own needs, if you want to have a grade, durable, or choose 304 stainless steel, although the price is more expensive, but if you pay attention to maintenance, you can use more than ten years of stainless steel bathroom hook and copper bathroom hook comparison.
Advantages of stainless steel hooks

1, the bathroom hook made of stainless steel has a great advantage in beauty, luxury, hygiene, environmental protection, durability, price and other aspects relative to the copper bathroom hook.
2, it is good for beauty. The best way to deal with the surface of copper products is nickel and chromium plating. The quality of electroplating layer is faster than that of the electroplating coating, and the speed is less than 10. Stainless steel kitchenware and tableware are popular all over the world. Because the polished stainless steel products always keep the white luster, never rust, use 10 years, 20 years, 30 years as long as you use clean water on the liniment, it is clean and bright, bright as new.
3, it is beneficial to the health, health and environmental protection of the human body. Copper products will lead to varying degrees and grow copper rust. The stainless steel hook products are acid resistant and alkali resistant, and are free from harmful substances.
4. Durable. The hardness of stainless steel is more than 2 times higher than that of copper. Never rust, never corrode, never deform.
5, the price, cheaper than copper products, stainless steel than copper price, surface treatment without electroplating directly polishing, saving electricity and plating fee, but the hardness of stainless steel is more difficult than copper, low speed, low efficiency, high labor cost. Therefore, there are individual styles which are not suitable for processing, and may not be cheaper than copper.

How to clean the oil stains and oil stains on the surface of the workpiece?

submission
The cleaning of oil pollution on the metal surface has been a major problem in the manufacturing industry. Because of improper maintenance of metal equipment, many factories disrupt production operations and affect the performance and profit of the enterprises. A large part of the reason is that enterprises do not understand the maintenance of metal equipment, and do not know how to carry out proper cleaning and maintenance. Then, what is the cleaning method of metal surface oil stain?
