Annular pipe fitting flattening and forming die

Abstract

The invention relates to the technical field of pipe fitting forming die, in particular to an annular pipe fitting flattening and forming die. The invention provides the annular pipe fitting flattening and forming die which comprises an upper die base and a lower die base, wherein an upper adjusting cushion block, a bolt, an upper edge pressing ring, an upper material pressing block, a nitrogen spring assembly and an upper die forming insert are arranged on the upper die base; the lower die base comprises an ejector rod cushion block, a lower material ejecting body, a lower die forming insert and a lower pressure-adjusting cushion block. The annular pipe fitting flattening and forming die has the benefits that compared with a traditional process, through an innovated process, the quantity of die procedures is reduced, the die manufacturing cost is reduced, the material utilization rate is improved, the human resource waste is reduced, the equipment loss is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting forming dies, in particular to a flattening and forming die for annular pipe fittings. Background technique [0002] In the sheet metal parts that make up the chassis of the car, there are some beams that are similar to the shape of "Ji". The shape of this type of parts is more complicated, and the two ends of the parts often have the shape of flanging in three directions. [0003] Therefore, the traditional process route has many mold processes, low material utilization rate, difficulty in sliding materials at both ends of the trimming T sequence, and a large number of presses in the stamping production line, resulting in waste of human resources, increased equipment consumption, low production efficiency, and excessive production costs. High disadvantage. Contents of the invention [0004] Aiming at the defects or deficiencies in the prior art, the technical problem to be solved by the p...
