For the first contact sheet metal processing people, the vast majority of people confuse the concept of sheet metal processing and stamping, although there are many similarities, but there are still certain differences.
First of all, sheet metal processing refers to the processing of sheet metal, which is made of plate made into common items in our daily life, such as chimneys, iron barrels, oil tanks, ventilation pipes, big heads, corners, funnels, etc. it is mainly through cutting, bending, bending, bending, welding and welding. The production technology of the product parts with certain shape, size and performance is obtained by using the power of conventional or special stamping equipment to make the sheet metal directly subjected to deformation force and deformation in the die. Sheet material, mould and equipment are the three elements of stamping process. From the above, it can be seen that stamping is only one of the many processes of sheet metal processing. The relationship between them is included and included, and the relationship between the two can help the employees to make fewer mistakes in the process of later operation and can be mentioned at the same time. The technical level of the high staff in the operation, for the partners who have just joined the sheet metal processing industry, should distinguish the difference between the sheet metal processing and the punching machine, so that it can be more helpful to the future work.
cut off
Cutting is a stamping process to separate materials from the open profile, and the separated material becomes a workpiece or process part.
Expansion
Flaring is a stamping process for expanding hollow parts or tubular parts outwards.
punching
Punching is a stamping process that separates waste from the material or process parts along the closed contour, and obtains the required holes in material or process parts.
Flushing
Blanking is a stamping process that separates waste from material or process parts along an open profile. The gap is formed by an open contour, and its depth is not greater than the width.
Flushing
Punching is a stamping process that separates waste along the open profile from material or process parts. The open profile is grooved and its depth exceeds the width.
Punching center hole
Punching center hole is a stamping process for forming shallow concave center holes on the surface of working parts, and there is no corresponding material on the back material.
Fine flushing
Fine blanking is one kind of bright and clean blanking. It makes use of the fine blanking die with the toothed pressure material plate to make the whole section of the punching piece all or basically clean.
Continuous mode
The progressive die is a die with two or more workstations, and the material is sent to a work station one by one with the stroke of the press.
Single process Die
The single process mold is a stamping die that only completes one process in a stroke of the press.
Combined punch die
The combined punching die is a set of universal and adjustable punching dies which are formed by various geometric elements (straight lines, angles, arcs, holes). The outline of a flat stamping part usually needs several combinations of punching dies.
Protruding
Pressing is a punching process that forces the material into the concave surface to form a protrusion by pressing the punch into the working part.
Embossing
Embossing is a punching process that forces partial crowding materials to form concave patterns, patterns, characters or symbols on the surface of process parts. The surface of the embossed surface does not correspond to a concave convex.
forming
Forming is a general term for stamping processes that rely on material flow instead of material separation to change the shape and size of working parts.
Bright and clean blanking
Smooth blanking is the direct and complete process of blanking the whole section without finishing. Twisting and twisting is a stamping process to twist a part of a straight or partial straight part to a certain angle.
Curling
Crimping is a stamping process that rolls the edges of the process parts into a closed circle. The axis of the rounded circle is in a straight line.
Coiling edge
The roll edge is a stamping process that rolls the upper edge of the hollow part close to the closed circle.
Drawing
Drawing is a stamping process that transforms straight wool or workpiece into curved surface. The surface is mainly formed by extending the material at the bottom of the punch.
Stretch bending
Tension bending is a stamping process under which the bending deformation of the whole bending cross section is subjected to tensile stress under the combined action of tension and bending moment.
Bulging
Bulging is a stamping process that expands hollow parts or tubular parts along the path.
Dissection
Cutting is a stamping process that divides the forming process into several parts.
Leveling
Leveling is a stamping process to improve the flatness of local or integral plane parts.
Undulating forming
Undulate forming is a stamping process that relies on the extension of materials to form part depression or bulge. The change of material thickness in undulate forming is unintentional, that is, a small amount of thickness change is formed naturally during the deformation process, not the design specified requirement.
Bend
Bending is a stamping process using pressure to cause plastic deformation of material and thus be bent to form a certain curvature and a certain angle.
Chisel
Chisel cutting is a process of blanking or punching with a sharp cutting edge. The chisel has no lower die, and the pad underneath the material is only a flat plate, and the most of the impact material is non-metallic.
Deep hole blanking
Deep hole blanking is a punching process with the aperture equal to or smaller than the thickness of the blanking material.
Blanking
Blanking is a stamping process to separate materials from the closed contour. The separated material becomes a workpiece or process part, and most of them are planar.
Necking
Necking is a punching process to reduce the opening of hollow parts or tubular parts.
plastic
Plastic is dependent on material
