Multi-station hydraulic drawing machine

Abstract

The invention relates to a hydraulic drawing device, in particular to a multi-station hydraulic drawing machine which comprises a base, a machine base bedplate, an upper oil cylinder bedplate, a middle column and columns, wherein the base is fixedly arranged on the ground, and the machine base bedplate is fixedly arranged on the base; the upper oil cylinder bedplate is supported between the upper oil cylinder bedplate and the machine base bedplate by the middle column and the columns, and a plurality of hydraulic cylinders are distributed on the upper oil cylinder bedplate in the circumferential direction; and a crank mechanism is arranged between the machine base bedplate and a working bedplate, and drives the working bedplate to move up and down, and mould stations are arranged on the working bedplate corresponding to the upper hydraulic cylinders. By arranging a plurality of independent mould stations on the drawing machine, the multiple drawing processes on the same product can be realized on the same drawing machine, so that the machining efficiency is improved.

Description

technical field [0001] The invention relates to hydraulic stretching equipment, in particular to a multi-station hydraulic stretching machine with high production efficiency, low labor intensity, high yield, low cost and good safety, belonging to the technical field of hydraulic stretching equipment. Background technique [0002] At present, four-column hydraulic stretching machines are mostly used for forming thin-plate products, and most of the stretched parts are not stretched at one time, but need to go through multiple processes to complete. Therefore, in the process of factory processing, each process corresponds to a hydraulic stretching machine, and processing a product requires multiple hydraulic stretching machines to form an assembly line. [0003] The existing hydraulic stretching machine has the following disadvantages in use: 1) The production efficiency is low and the labor intensity is high. The workers in charge of each process repeat the same mechanical ac...

[0003] The existing hydraulic stretching machines have the following disadvantages in use: 1) Low production efficiency and high labor intensity

The workers in charge of each process repeat the same mechanical action every day, the labor intensity is relatively high, and the workers need to rest, which invisibly reduces the production time and reduces the production efficiency; 2) The yield is relatively low, due to the repetitive labor of the workers High strength, prone to fatigue, so there will be more mistakes in the processing process, resulting in product scrap; 3) High energy consumption, each process requires a corresponding hydraulic stretching machine, so the number of hydraulic stretching machines is large , will consume more energy; 4) The labor cost is high. Due to the large number of machines required for processing, each machine requires at least one worker, and some workers who coordinate between different processes are also required. Therefore, the number of workers More, higher labor costs; 5) Low safety factor, because workers need to go deep into the machine to operate, when workers misuse or the machine breaks down, it is easy to cause casualties
