Forming finish machining process for hydraulic accessories of hydraulic transmission system

Abstract

The invention relates to a forming finish machining process for hydraulic accessories of a hydraulic transmission system. A frame body, a conveying device, a fixing device, an internal expanding device and coating devices are included. The conveying device is arranged at the lower end in the frame body; the fixing device is installed at the position, close to the left end, of the upper end of the conveying device; the internal expanding device is arranged at the position, close to the right end, of the upper end face in the frame body; and the coating devices are symmetrically installed on the front side wall and the rear side wall of the frame body below the internal expanding device. The forming finish machining process for the hydraulic accessories of the hydraulic transmission system solves the following problems possibly occurring in the process of actually smearing an anti-rust coating on a cylinder barrel of an existing hydraulic accessory: a, the anti-rust coating is sprayed on the outer surface of the cylinder barrel by manually operating a spraying gun, the spraying mode is relatively tedious, the consumed time is relatively long, and the spraying efficiency is relatively low; and b, the spraying gun is manually operated to work, such that anti-rust paint is easily wasted, the anti-rust paint can be possibly inhaled by a worker, and a certain harm is caused to the body of the worker.

Description

technical field [0001] The invention relates to the field of manufacturing hydraulic fittings of a hydraulic transmission system, in particular to a molding and finishing process of hydraulic fittings of a hydraulic transmission system. Background technique [0002] The hydraulic transmission system is a hydraulic system composed of hydraulic components, hydraulic control components, hydraulic actuators, hydraulic accessories and hydraulic oil. Most of the hydraulic components are hydraulic cylinders, and the cylinder barrel is one of the main accessories of the hydraulic cylinder. When these cylinders are manufactured and shaped, it is usually necessary to apply a layer of anti-rust coating on their surface, so that the cylinders have a certain anti-rust function, thereby prolonging their service life. [0003] At present, the cylinder barrels of existing hydraulic accessories may encounter the following problems in the process of actually applying the antirust layer: a. Th...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the following problems that the cylinder barrel of the existing hydraulic fittings may encounter in the process of actually applying the antirust layer: a. spray the antirust coating on the outer surface of the cylinder barrel by manually operating the spray gun, The spraying method is cumbersome and takes a long time, resulting in low spraying efficiency; b. Manual operation of the spray gun is likely to cause waste of anti-rust paint, and the anti-rust paint may be artificially inhaled, thus causing certain damage to the artificial body. s damage
