Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the present embodiments do not constitute any limitation to the present invention.
[0024] see figure 1 , a method for replacing the sealing ring of the main cylinder of a multi-directional die forging press, which is carried out according to the following steps:
[0025] (1) After determining the maintenance plan of the press, start to build the disassembly platform. The first floor disassembly platform is located at the height of the lower bottom of the upper semicircular beam 4, and is used to remove the connecting bolts between the upper semicircular beam 4 and the master cylinder and the internal sensor 1 of the master cylinder; Pipes and valves connected to hydraulic cylinders.
[0026] (2) The demolition platform is constructed by directly welding square steel pipes on the press frame, and a steel platform is laid on the platform for walki...

The invention relates to a method for replacing a sealing ring of a main cylinder of a multidirectional die forging press. Including: building and dismantling platform; hydraulic system oil return, dismantling hydraulic pipeline and valve body; dismantling clamping cylinder on both sides; The weight makes the return cylinder return; unscrew the sensor, and remove the connecting bolts between the bottom of the master cylinder and the cylinder body; lift the return cylinder, and return the master cylinder and other cylinders to their original positions; lift the sensor through the gap of the upper semicircle beam To be completely close to the inner highest point of the upper semi-circular beam, and tighten the connecting bolts between the upper semi-circular beam and the master cylinder base; the return cylinder returns to the stroke again, at this time the sensor is separated from the master cylinder bottom and the master cylinder piston; the master cylinder sealing ring is replaced; the master cylinder After the replacement of the cylinder seal is completed, reverse the above steps and re-install the master cylinder. The replacement process of the invention is simple and easy to operate, the replacement speed is fast, the efficiency is high, the maintenance cost is saved, the production efficiency is improved, and the invention is economical, applicable and easy to popularize.
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...
