Multi-station hydraulic stretcher with transposition manipulator

Abstract

The invention relates to a multi-station hydraulic stretcher with a transposition manipulator, which comprises a base, a bed bedplate, an upper oil cylinder bedplate, a middle upright, a peripheral upright and the transposition manipulator. The base is fixed on the ground; the bed bedplate is fixed on the base; the middle upright and the peripheral upright support the upper oil cylinder bedplate and a working bedplate between the upper oil cylinder bedplate and the bed bedplate; a plurality of upper hydraulic cylinders are distributed on the upper oil cylinder bedplate in the peripheral direction; a crankshaft mechanism is arranged between the bed bedplate and the working bedplate; the working bedplate is driven to move up and down by the crankshaft mechanism; the positions on the working bedplate, which correspond to the upper hydraulic cylinders, are provided with die stations; the transposition manipulator is arranged on the working bedplate and can rotate left and right to clamp and put down a workpiece; according to the invention, a plurality of independent die stations are arranged on the stretcher, so that the repeated stretching process on the same product on the same stretcher can be implemented; and meanwhile, the transposition manipulator can be used for carrying out automatic transposition on the workpiece.

Description

technical field [0001] The present invention relates to a hydraulic stretching equipment, in particular to a multi-station with transposition manipulator with high flexibility, good operability, high production efficiency, low labor intensity, high yield, low cost and good safety. A hydraulic stretching machine belongs to the technical field of hydraulic stretching equipment. Background technique [0002] At present, four-column hydraulic stretching machines are used to complete the pressed and formed products, and most of the stretched formed 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 lab...

Problems solved by technology

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

The workers responsible for 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

[0004] At present, multi-station presses have been put into the market, but most of the multi-station presses are multi-station punching machines, while multi-station hydraulic stretching machines are rare

Multi-station presses mostly adopt linear arrangement of stations, the rising of the workpiece moves out of the mold area, the linear transposition action, and the action of dropping the workpiece into the mold area is mostly realized by mechanical transmission. During the processing, some parts of the transmission mechanism need to be adjusted. The parts are adapted to different molds, the flexibility is not high, and the operability is poor
