Stamping Die Cleaning

What shape does Dalian stamping die make of punch and die, and what shape is the part drawn out? The main working principle of drawing die is to deform the required material according to the shape people need. For example, stretch a flat plate into barrels, bowls, basins, etc. Mould disassembly can only be carried out by checking the condition of the mould, confirming the cause of the failure, finding out the problem and cleaning the mould.


When removing the mould, the force should be uniform, aiming at the stripping spring in the fixed plate and stripping plate. Find out the problem, and then clean up the mould, before removing the mould. When removing the die, the force should be uniform. Aiming at the die structure where the stripping spring is between the fixed plate and the stripping plate and the stripping spring is directly mounted on the inner guide pillar, the stripping plate should be disassembled to ensure the unbalanced ejection, and the inclination of the stripping plate may lead to the fracture of the punch in the die.


At the same time, it is necessary to check whether the corresponding die has broken edge and whether it needs grinding edge. Assemble the punch to check whether there is enough gap between the punch and the fixed block or the fixed plate, and check whether there is any movement allowance for the pressed block. The assembly die should be placed horizontally, and then laid on the surface of the die with a flat iron block, such as copper rod, tapping it in place, not obliquely and forcefully, and the bottom of the die should be chamfered. After installation, check whether the concave die surface is equal to the surface.


Attention should be paid to the confirmation of screw locking of stripper. When locking, it should be from inside to outside, balanced and cross-locked. One screw should not be locked first and then another screw should be locked, so as not to cause the stripper to tilt and cause the punch to break or the die precision to decrease. It will affect the pressing accuracy of materials, resulting in abnormal product size, instability and so on. It is necessary to repair or re-grind the stripping insert and stripping plate.


The contour sleeve should be checked for its accuracy. If it is not equal in height, the stripper will be inclined. Its precise guidance and smooth elastic pressure function will be destroyed and must be maintained. Marking can be made at the edge of the die for subsequent maintenance. Daily production should pay attention to collecting and preserving the material belt when the original die is in good condition. If the follow-up production is not smooth or the die changes, it can be used as a reference for the maintenance of the die.
