[CN 201821676028.7] Hydraulic tensioning device for extrusion hydraulic press
[CN 201821676028.7] Title of a hydraulic tensioning device for an extrusion hydraulic press: Application number of a hydraulic tensioning device for an extrusion hydraulic press: CN 201821676028.7 Applicant: Sparid (Tianjin) Machinery Technology Co., Ltd. Application date: 2018-10-16 Patent Type: Utility Model The utility model discloses a hydraulic tensioning device for an extrusion hydraulic press, comprising a shell, inside which a piston column is arranged, the bottom end of the piston column is fixedly connected with a sealing groove, the surface of the piston column is sleeved with a piston sleeve, the bottom of the surface of the piston column is sleeved with a sleeve, and the outer surface of the sleeve is sleeved with a first spring, the top of the outer surface of the housing is sleeved with a dust-proof component, and the bottom of the outer surface of the housing is sleeved with a cushioning and noise reduction mechanism. The utility model relieves the vibration force of the shell through the vibration damping mechanism, eliminates the noise generated inside the shell, and isolates the external dust through the dust-proof component, which solves the existing hydraulic tension The device itself does not have the effect of shock absorption and protection. The hydraulic tensioning device for the extrusion hydraulic press has the advantages of shock absorption and noise reduction, and improves the stability of the use of the tensioning device.
