Hydraulic tube expansion device achieving cleaning effect

Abstract

The invention discloses a hydraulic tube expansion device achieving a cleaning effect. The hydraulic tube expansion device comprises a worktable, a hydraulic cylinder and a liquid storage tank; the hydraulic cylinder and the liquid storage tank are arranged on the worktable; the rear end of the liquid storage tank is provided with a sealing push block; a piston rod of the hydraulic cylinder is fixedly connected with the sealing push block; the worktable is vertically provided with a fixing plate; a liquid outlet of the liquid storage tank is fixedly connected with a flow guide joint; the end,far away from the liquid storage tank, of the flow guide joint penetrates through the fixing plate and is connected with a tube expander; a cleaning tube is arranged over the tube expander; one end ofthe cleaning tube is fixed to the fixing plate; the cleaning tube is provided with an outer tube wall and an inner tube wall; the front and rear ends of the outer tube wall and the inner tube wall are sealed to form a cleaning chamber; the outer tube wall is provided with a plurality of cleaning holes; and the end, close to the fixing plate, of the cleaning chamber is provided with a water charging pipe.

Description

technical field [0001] The invention relates to the field of pipe body processing, in particular to a hydraulic pipe expansion device. Background technique [0002] The hydraulic tube expander is used to enlarge the diameter of the end of the metal tube body and flatten the corrugation of its side wall. The existing tube expander does not have the function of cleaning the end of the metal tube body. There are often impurities such as metal burrs or metal debris at the end of the metal tube body. The presence of impurities will not only cause uneven expansion of the inner wall of the tube The phenomenon will affect the tube expansion effect, and the metal burr will cause damage to the expansion and pressure part. In addition, metal debris will remain on the expansion and compression part after the tube is expanded. If it cannot be removed in time, it will affect the quality of the subsequent expansion tube, and will cause a large degree of damage to the expansion and compres...

Problems solved by technology

The existing tube expander does not have the function of cleaning the end of the metal tube body. There are often impurities such as metal burrs or metal debris at the end of the metal tube body. The presence of impurities will not only cause uneven expansion of the inner wall of the tube Phenomenon will affect the expansion effect, and the metal burr will cause damage to the expansion and pressure part

In addition, metal debris will remain on the expansion and compression part after expansion. If it cannot be removed in time, it will affect the quality of the subsequent expansion tube, and it will cause great damage to the expansion and compression part after a long time.
