A double-sided punching device for an overturned automobile flange

Abstract

The invention discloses a turning type two-sided punching device for automotive flange discs. The punching device comprises a supporting pad, an upper turning plate and a lower turning plate, a working table is connected to the upper end of the supporting pad, hydraulic cylinders are connected to the two sides of the upper end of the working table, a hydraulic shaft is connected to the upper end of each hydraulic cylinder, and a lifting plate is connected to the upper ends of the hydraulic shafts; supporting racks are connected to the middle portion of the upper end of the working table, a turning shaft is connected to the middle portion of the upper end of each supporting rack, a sliding slot block is connected to the inner side of each turning shaft, spring slots are connected to the middle portions of the outer ends of each sliding slot block, a damping spring is connected in each spring slot, a rolling ball is connected to the inner side of each damping spring, threaded sleeves are arranged on the middle portions of the inner ends of each sliding slot block, and a fastening screw is connected to the middle portion of each threaded sleeve; and the middle portion of the upper turning plate and the middle portion of the lower turning plate are each provided with clamping plates. According to the turning type two-sided punching device for the automotive flange discs, two-sided punching machining on the automotive flange discs is achieved, reclamping in the machining process of the flange discs is avoided, the machining precision is improved, the working efficiency is improved, and meanwhile all-directional machining on the automotive flange discs is met.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a double-sided punching device for an overturned auto flange. Background technique [0002] Flanges are referred to as flanges for short, and they are just a general term. They usually refer to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things. This thing is widely used in machinery, so it looks strange, as long as it looks like a flange, it is connected to the pipe end. There are holes in the flange, and bolts can be worn to make the two flanges tightly connected, and the flanges are sealed with gaskets. Flange pipe fittings refer to pipe fittings with flanges (flanges or lands). It can be cast, screwed or welded. [0003] There are many flange connections in automobiles, and flanges need to be processed on both sides, but the flanges in the prior art are processed on one side of the flange before re-clamping...

AI Technical Summary

Problems solved by technology

[0003] There are many flange connections in automobiles, and flanges need to be processed on both sides, but the flanges in the prior art are processed on one side of the flange before re-clamping. Processing on the other side, these not only affect the processing accuracy, but also affect the production efficiency
