The experience of stamping parts manufacturers: how to confirm the structure of stamping parts die

Experience sharing of stamping parts manufacturers: how to define the structure of stamping parts die. The structure of the mold must be comprehensively considered according to the various factors of the shape accuracy of the stamping. On the premise of meeting the quality of stamping parts, to minimize the production cost of stamping parts and determine the structure of the mold, many problems must be solved. As we all know: the classification of mold types, simple molds, compound molds, progressive molds, etc., and the classification and determination of operation methods. Manual operation, automatic operation, semi-automatic operation, etc., the determination of the way of feeding and discharging, the determination of the way of pressing and unloading, it is necessary to choose the accuracy and method reasonably. The designer of the stamping parts manufacturer should also consider the maintenance performance, operation aspect, safety performance and other aspects of the mold when designing the blanking die. For example: there are many working parts of the die, and the service life of the die is also very different. Those easy to wear and easy to wear working parts should be made into a quick-change structure, and as far as possible, it can be adjusted and compensated separately. The size of the parts that are easy to wear. The structure of the mold should ensure that the operator's hand does not have to enter the dangerous area, and the structural dimensions of each movable part should be ensured so that the operator's hand will not be crushed within its movement range. Due to the choice of composite mold, the structure of the composite mold can be divided into two types: formal and inverted. The selection of the composite mold mechanism needs to consider the following issues: In order to facilitate the operation, if the punching waste does not appear in the working area of u200bu200bthe mold, then a flip-chip composite mold structure can be used to facilitate the punching waste to pass through the punch and concave die holes. Leaking down. Starting from the strength of the male and female molds, if the wall thickness of the male and female molds is small, a formal structure should be adopted. If the outer size of the concave mold is too large, when the upper mold can accommodate the lower mold, the flip-chip structure is adopted first. If the upper mold cannot accommodate the concave mold, the formal structure can be considered at this time. If the parts have higher flatness requirements, the use of a formal structure will achieve better results. However, when an elastic pushing device is used, the structure of the composite mold should be considered first. Considering the above structure, in order to facilitate operation and improve production, the design of the stamping parts manufacturer adopts a flip-chip composite mold structure. Preliminary selection of parts is to use rigid pushing device to push out, unloading using rubber, using middle guide pillar mold base [Related recommendation] Learn more: How much do you know about new energy automobile stamping parts?
