Forging Press Return Cylinder Replacement Technology

Abstract

The invention provides a replacement technology of a return cylinder of a forging machine. The return cylinder comprises a cylinder body and a plunger. The top of the cylinder body is connected to a moving beam of the forging machine, and the bottom of the plunger is connected to a lower transverse beam. The replacement technology of the return cylinder of the forging machine comprises the following disassembling steps that S1, two reverse chains are arranged on the two sides of the return cylinder correspondingly; S2, the plunger and the lower transverse beam are separated; S3, the plunger ascends; S4, a snap ring is arranged on the peripheral wall of the plunger, and the snap ring and the cylinder body are fixedly connected; S5, a third reverse chain is arranged on the moving chain; S6,the cylinder body and the moving beam are separated, and the first reverse chain and the third reverse chain are adjusted so that the return cylinder can be gradually inclined; and S7, after the return cylinder is inclined to a certain angle, the top end of the cylinder body is connected with a hoisting device, the position of the return cylinder is adjusted through the hoisting device and the first reverse chain, and therefore the return cylinder can be smoothly moved out of the ground. According to the replacement technology of the return cylinder of the forging machine, due to the fact thatthe snap ring is installed, the plunger is prevented from being separated from the cylinder body; and then the return cylinder is transported in a reverse mode through the reverse chains, the safetyof construction is improved, the replacement efficiency is improved, and the labor load is reduced.

Description

technical field [0001] The invention relates to the field of maintenance of forging presses, in particular to a process for replacing return cylinders of forging presses. Background technique [0002] The return cylinder is an important piece of equipment in the forging equipment. It is mainly responsible for the return movement after the forging press action. The frequency of its up and down movement is very high, and its quality directly affects whether the equipment can be produced normally. The form of damage is often due to long-term high-load operation resulting in oil leakage from the oil cylinder seal, wear and tear of the copper sleeve, etc., which need to be replaced regularly. The replacement of the return cylinder in the prior art is that the hoisting operator binds the cylinder body and the plunger together by means of wire rope winding, and the plunger and the cylinder body are locked by the upward lifting force of the crown block and lifted out as a whole.

Problems solved by technology

Since part of the return cylinder is inside the pit, bumps are often caused during the lifting process, and even the surface of the plunger may be scratched due to improper operation, and the lifting is oblique, and the safety cannot be guaranteed
