Multidirectional die forging press main cylinder seal ring replacement method

Abstract

The invention relates to a multidirectional die forging press main cylinder seal ring replacement method. The method includes the steps that a disassembly platform is erected; oil return of a hydraulic system is carried out, and a hydraulic pipe and a valve are disassembled; die assembly cylinders on the two sides are disassembled; sensor connecting lines are disassembled, an upper half round beam and a sensor locking bolt are disassembled, the valve is opened, and a return cylinder returns by means of self weights of a working table and a hydraulic cylinder; a sensor is screwed open, a connecting bolt for the cylinder bottom of a main cylinder and a cylinder body is removed; the return cylinder is jacked, and the main cylinder and other cylinders are jacked to original positions; the sensor is lifted to be completely close to the highest point inside the upper half round beam through a gap of the upper half round beam, and a connecting bolt of the upper half round beam and a base of the main cylinder are fastened; the return cylinder returns again, and the sensor is separated from the cylinder bottom of the main cylinder and a main cylinder piston at the time; a main cylinder seal ring is replaced; and the above steps are reversely executed after the main cylinder seal ring is replaced, and the main cylinder is installed again. According to the multidirectional die forging press main cylinder seal ring replacement method, the replacement process is simple, the method is easy to operate, high in replacement speed, high in efficiency, economical, applicable and easy to popularize, the maintaining cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for maintaining and overhauling main components of large-scale equipment, in particular to a method for replacing a sealing ring of a main cylinder of a multi-directional die forging press. Background technique [0002] The multi-directional die forging press is a press with multiple slides in vertical and horizontal directions. As the development direction of die forging presses, multi-directional die forging presses have obvious advantages such as reducing product costs and shortening production cycles, and the advantages of one-time forming are becoming more and more obvious in the gradual development. But at the same time, the update and maintenance of its equipment is also particularly important, and due to the complexity and high precision of the equipment, it is more difficult in the maintenance process. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems in the...
