Precautions and size requirements for the production of metal stamping parts

1. Reasonable mold design: In the progressive die, the organization of the next material may affect the precision of the stamping parts forming. In view of the fine parts of the stamping parts, the general first tissue of a large area of punching and cutting materials, and then the organization of a smaller area of punching and cutting materials, in order to reduce the punching force hedging pressure parts forming effect.

2. Daily mold production, should pay attention to protect the sharp degree of punching convex, concave die edge. When the cutting edge wear, the tensile stress of the data will increase, and then the stamping parts attack Flip, distortion trend increases.

3. Add the pressure function: that is, the discharge insert pressure Part thickening Scale (normal discharge insert thick h+0.03mm), in order to increase the stress on the concave side of the data, and then suppress the punching of the stamping parts, distortion deformation.

4. Repair the bevel or arc at the end of the convex edge: This is an effective way to reduce the cushioning force. Slow down the punching force, you can reduce the tensile force on the concave side of the data, and then reach the role of suppressed stamping parts attack flip, distorted.

5. Pressurized data: Defeat the traditional mold design structure, in the discharge board out of the material open space (that is, when the mold is closed, the discharge plate and the concave mold fit, while the space to hold the data discharge plate and the concave mold for the information thickness t-0.03~0.05mm). In this way, the stamping plate movement is smooth, and the data can be pressed tightly. The key forming part, the unloading plate must be made into a block structure,Metal Stamping PartsManufacturers for you to clarify, in order to deal with long stamping caused by the discharge plate pressure site Attack of the grinding (pressure) loss, and can not tighten the data.

1, punching when the attack on the edge of the punch caused. Need to study the cutting edge, and pay attention to see if the punching gap is reasonable. Caused by the instability of the stamping parts during bending. The first is for U-shaped and V-shaped bends. The treatment of this problem, the guide position before bending of the stamping parts, the guide position in the bending process, and the pressing data during the bending process to prevent the stamping parts from slipping during bending are the main points to solve the problem. caused by the punching edge of a seizure during punching. Need to study the cutting edge, and pay attention to see if the punching gap is reasonable.

2, when the cutting edge wear, the tensile stress of the data increases, stamping parts attack Flip, distortion trend increased. When the seizure is flipped, the punching scale will become smaller. The pressure on the data, so that the data attack plastic deformation, will lead to greater punching scale. And when the pressure is reduced, the punching scale will become smaller.

3, the end shape of the convex die edge. If the end of the slope or arc, due to the relief of punching force, punching parts easy to attack flip, slander, therefore, the punching scale will become larger. When the end of the convex die is planar (no bevel or arc), the punching scale will be relatively small. In the detailed operation of the actual situation, we should make a detailed explanation of the detailed title problem, so as to find out the countermeasures to solve the problem.
