Side punching type progressive die for bending forming of rocker arm body

Abstract

The invention discloses a side punching type progressive die for bending forming of a rocker arm body. The side punching type progressive die comprises bending forming devices arranged on a bending forming station for conducting bending forming on a material belt, and a side punching device inclined towards the punching station and arranged behind the bending forming station. At least two sets of bending forming devices are arranged, and two or more steps are needed for bending forming. The side punching device is used for punching symmetric side holes in the side wall of a part blank obtained after bending forming of the material belt and comprises an upper die, a lower die, a discharging structure and a lateral punching structure. Due to the fact that the side punching type progressive die for bending forming of the rocker arm body is formed by combining bending forming dies and lateral punching dies, compared with an existing manner of machining this kind of parts through multiple pairs of dies and a single process, the machining efficiency is greatly improved, and the requirement for mass production can be met; meanwhile, the labor cost is greatly reduced, and an operator conducts operate more easily; and in addition, precision errors caused by carrying of the workpiece blank between among stations are avoided, and therefore the machining precision is higher, and the quality stability is also better.

Description

technical field [0001] The invention relates to the technical field of die design, in particular to a continuous stamping die of side punch type for bending forming. Background technique [0002] Progressive die is a relatively advanced die in production and processing at the present stage. It combines multiple dies together to form a single-process die, thereby realizing automatic production of various processes. It has the advantages of good processing quality, high production efficiency, and fewer operators. It is a major direction of mold design development at this stage. The processing of bending and forming side punching parts requires not only bending and forming, but also two or more side punchings, which is complicated. At present, such products generally use casting technology to process blanks, and then multiple pairs of Single-process molds are processed, and the above methods usually have the defects of low processing efficiency and unguaranteed product quality...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above problems, the present invention provides a continuous stamping die of bending and forming side punching type, which solves the problem that in the prior art, such as rocker body, parts that need to be bent and formed and punched sideways can only use multiple sets of dies. The problem of single-process processing, and has the advantages of low production cost, high efficiency and high safety factor
