What are the basic parts of stamping
Release time:2024-01-11 11:25
1. Working parts: parts that complete stamping work; including punch and die and other parts.
2. Positioning parts: It is to ensure good guidance and control the feeding distance when feeding; It mainly includes parts such as stop pin, positioning pin, side blade, etc.
3. Pressing, unloading and topping parts: The function of these parts is to ensure the elimination of parts and waste after the stamping process is completed; it mainly includes parts such as discharge plate, topper, pneumatic topping device, etc.
4. Guide parts: It is to ensure accurate guidance when the upper mold and the lower mold move relative to each other, so that there is a uniform gap between the punch and the female mold, and improve the quality of the stamping parts; including guide posts, guide sleeves, guide plates and other parts.
5. Install and fix parts: The function of these parts is to connect the above four parts as a whole, ensure the relative position of each part, and enable the mold to be installed on the press; including upper template, lower template, mold handle, fixed plate, backing plate, screw, cylindrical pin, etc.
6. Buffer parts: including discharge spring, polyurethane rubber and nitrogen cylinder, etc.
7. Safety parts and other auxiliary parts: mainly include safety side pins, safety screws, working limiters, storage limiters, loading and unloading racks, waste chute, lifting rods, lifting lugs, etc.

Common problems of precision stamping
Release time:2024-01-11 11:23
Common problems in metal stamping include: deformation and burrs of precision stamping parts; cracks, warping, surface scratches, angular deformation, etc. of bent parts; flange wrinkling, deep drawing wall wrinkling, deep drawing wall damage, cracking, etc. of drawn parts; Flanging cracks, uneven bulging, etc.
The solution to common problems: mold design should have a reasonable convex and concave mold clearance values, fillet radius and processing accuracy. When designing the bending die, effective measures should be taken to reduce the springback and the springback amount should be subtracted from the die. Reasonable fillet should be designed to prevent bending and cracking. When drawing, use the edge holder ring to prevent wrinkling, and the pressure should be moderate; Use proper lubrication to reduce the drawing resistance to prevent the die from sticking or pulling through the workpiece; Use professional stamping oil that meets the process requirements.

Advantages of precision stamping
Release time:2024-01-11 11:22
1. The production efficiency of stamping processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because the stamping is to rely on the die and stamping equipment to complete the processing, the number of ordinary press strokes per minute up to dozens of times, high-speed pressure up to hundreds of times per minute or even more than a thousand times, and each stamping stroke may get a punch.
2. When stamping, the die ensures the size and shape accuracy of the stamping parts, and generally does not destroy the surface quality of the stamping parts, and the life of the die is generally longer, so the quality of the stamping is stable, the interchangeability is good, and it has the characteristics of "exactly the same.
3. Stamping can process parts with a large size range and complex shapes, such as stopwatches as small as clocks and watches, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation and hardening effect of the material during stamping, the strength and rigidity of the stamping Both are higher.
4. Stamping generally has no chip generation, less material consumption, and no other heating equipment, so it is a kind of material saving, energy-saving processing method, and the cost of stamping parts is low.
