Abstract

The invention provides a flexible scroll power-assisted, automatic slag cleaning and no backlog hydraulic cylinder, which mainly includes a cylinder barrel, an end cover A, an end cover B, a piston rod, a piston, a buffer block, a guide sleeve and a buffer pad. Its characteristics are that the piston with spiral flow channel can play a flexible vortex assistance, and the buffer block with the slag cleaning flow channel can automatically remove the slag. The invention realizes the flexible vortex force-increasing start when the piston rod extends and the buffer stillness when retracting through the blind hole of the round table with the spiral flow channel; automatic slag removal is realized through the slag cleaning flow channel on the buffer block; The 45° inclined annular oil channel on the upper side realizes the buffering stillness without backlog when the piston rod is extended and the acceleration start when retracting.

Description

technical field [0001] The invention relates to a flexible vortex power-assisted, automatic slag-cleaning and no-backlog hydraulic cylinder, in particular to a circular platform blind hole with a spiral flow channel to realize the flexible vortex power-intensive start and retraction when the piston rod is extended. Buffer static when the piston rod is extended; automatic slag removal is realized through the slag clearing channel on the buffer block; 45° inclined annular oil passage on the guide sleeve realizes buffer static without backlog when the piston rod is extended and accelerated start when retracting , which belongs to the technical research and development field of hydraulic cylinders. Background technique [0002] Hydraulic cylinders use the linear reciprocating motion of the piston to convert hydraulic energy into mechanical energy. However, due to the singleness of the current hydraulic cylinder structure, the following problems are caused: one is the large star...
