Stamping die with irregular holes distributed in axial direction of round pipe

Abstract

The invention discloses a stamping die with irregular holes distributed in an axial direction of a round pipe. An upper die structure comprises an upper die plate, circular male dies, a male die fixing plate and an elastic discharging device; a lower die structure comprises a lower die, a lower die plate, a supporting base and an indexing positioning device; the multi-group circular male dies areinvolved and are arranged in detachable structure, and the number of the groups is the same as the number of the holes distributed in the axial direction of a machined round pipe; the circular male dies are arranged along the axial direction of the lower die by taking the indexing positioning device as a reference; and indexing of the indexing positioning device and the angle distribution of eachhole in a machined round pipe fitting in the radial circumference is in one-to-one correspondence. According to the one-die stamping multihole die, the stamping precision is used as the reference through the indexing positioning device, the reliability and the uniqueness of the positioning reference are achieved, the precision of the angle and the size of a round pipe product in the radial direction is guaranteed, and the positioning reference can be easily found during stamping in each time; and in the aspect of a die device, the plurality of circular male dies which can be arranged in a modularized mode and in a quickly disassembled and assembled mode is adopted as upper dies, so that the labor cost and the die cost are saved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die with irregular holes distributed in the axial direction of a circular tube. Background technique [0002] With the rapid development of the domestic auto market and the increasing demand for lightweight auto parts, more and more technical requirements for welded pipe extended processing products urgently need to be strongly guaranteed by auto parts suppliers. At present, new designs for extended products of welded pipes for automobiles, such as figure 2 As shown in , the round tube product has multiple round holes and multiple elongated holes that need to be processed and guaranteed. In addition to the dimensional accuracy requirements for multiple holes, there are also requirements for axial distance dimensions and radial angular dimensions. [0003] The processing methods conventionally used in the past can be basically divided into: machining method and s...

AI Technical Summary

Problems solved by technology

The shortcomings of the machining method are obvious, the processing method is rough, the size and position accuracy of the processed product is low, and the processing efficiency is also low; the stamping method of the general structure also has many problems, because the process method and positioning device are not clever and reasonable enough. , the position accuracy of the porous position is not easy to guarantee. In addition, there are many punching processes and molds, and the cost of manpower and molds is high. Since multi-process debugging and handling molds are required, the production efficiency is also affected to a certain extent. So many process processing problems often Restricting the production capacity needs of this type of round tube products
