Working cylinder sleeve sealing structure of forging press

Abstract

A power deceleration device for a forging press adopts the structure that a worm, a worm gear and an output shaft are mounted in a gear box; one end of an electromagnetic clutch device is connected with the worm; the other end of the electromagnetic clutch device is mounted on the inner wall side of the gear box; a rotary coding device is mounted on the output shaft on one side of the worm gear, and is mounted on the forging press body through the output shaft; a variable speed motor is mounted on the electromagnetic clutch device; and the output shaft of the variable speed motor is butted with the electromagnetic clutch device. Adopting the structure with the gear box, the electromagnetic clutch device and the rotary coding device, the power deceleration device has the advantages that the structure is compact; the mechanism is simple; the occupied area is small; the probability of damage is low; and the maintenance is convenient.

Description

technical field [0001] The invention relates to a working cylinder liner sealing structure, in particular to a working cylinder liner sealing structure of a forging machine, and belongs to the technical field of working cylinder liner sealing. Background technique [0002] The sealing structure of the working cylinder liner of the forging machinery is an important part in the work of the forging machinery. Its main function is to adjust the normal operation and storage and release of the forging machinery. Air leakage occurs between the sleeves. The main reason for this phenomenon is that the sealing ring of the working cylinder sleeve is made of non-metallic asbestos rubber sheets. In addition, the working environment of the forging machinery is relatively harsh, which accelerates the sealing of asbestos rubber sheets. Therefore, the currently used working cylinder liner sealing ring has the defects of easy aging, easy air leakage and easy damage. SUMMARY OF THE INVENTION...

Problems solved by technology

[0002] The sealing structure of the working cylinder liner of the forging machine is an important accessory in the work of the forging machine. Its main function is to coordinate the normal operation and storage and release of the forging machine. At present, in all the working cylinder liner structures of the forging machine, there are generally working cylinders and Air leakage occurs between the sleeves. The main reason for this phenomenon is that the sealing ring of the working cylinder liner is made of non-metallic asbestos rubber sheet. In addition, the working environment of the forging machine is relatively harsh, which accelerates the sealing of the asbestos rubber sheet. The aging of the ring, so the current working cylinder liner sealing ring has the defects of easy aging, easy air leakage and easy damage
