Car roof side beam die punching machine with precise positioning function

Abstract

The invention relates to a punching machine technology, aims to solve the problems of large positioning error and more time consumption caused by inconvenient movement of a car roof side beam processing plate on a punching machine, and particularly relates to a car roof side beam die punching machine capable of accurately positioning, which comprises a base frame, an upper frame, a disc wheel, a lower die and a disc wheel shaft, and the upper frame is integrally formed at the upper end of the base frame; a plate wheel rotating by a punching machine sequentially drives forward and reverse threaded rods to rotate under the action of an adjusting push rod, so that a reciprocating plate extrudes a roller shaft, a roller on the roller shaft supports a rectangular to-be-machined plate placed on a lower die, friction between the plate and the lower die is reduced, and machining precision is improved. A disc wheel rotating through a punching machine drives a bidirectional screw rod to rotate under the action of an adjusting push rod, so that a supporting frame on the bidirectional screw rod carries out centering clamping operation on a rectangular to-be-machined plate placed on a lower die, and the left-right position of the rectangular to-be-machined plate on the lower die is adjusted without manual adjustment.

Description

technical field [0001] The invention relates to a punching machine technology, in particular to a precisely positioned roof side beam die punching machine. Background technique [0002] The stamping machine applies pressure to the material to plastically deform it to obtain the required shape and precision. Therefore, a set of molds must be matched to place the material in between, and the machine will apply pressure to deform it. The force applied to the material during processing The resulting reaction force is absorbed by the punching machine body; [0003] In the prior art, during the stamping process of the roof side beam by the stamping machine, due to the large area of ​​the rectangular plate to be processed and the heavy weight, the plate is placed on the lower die of the punching machine and is separated from the lower die. The frictional resistance between them is large, and it is difficult for the staff to make fine adjustments to the position of the plates, and ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is that the rotating disc wheel of the stamping machine drives the positive and negative threaded rods to rotate sequentially under the action of the adjusting push rod, so that the reciprocating plate squeezes the roller shaft, so that the roller on the roller shaft is aligned with the rectangular shape placed on the lower mold. The plate to be processed is supported to reduce the friction with the lower mold. The disc wheel rotated by the punching machine drives the two-way screw to rotate under the action of the adjustment push rod, so that the support frame on the two-way screw will be placed on the lower mold. The center clamping operation of the rectangular plate to be processed makes it unnecessary to manually adjust the left and right position of the rectangular plate to be processed on the lower mold, and solves the problem of large positioning errors and time-consuming problems caused by the inconvenient movement of the roof side beam processing plate on the punching machine problem, and propose a precise positioning roof side beam die stamping machine
