Abstract

The invention discloses a hydraulic extruding machine for a ceramic roller billet tube. The hydraulic extruding machine is used for extrusion molding of the ceramic roller billet tube. The hydraulic extruding machine comprises an oil cylinder, a vacuum box, a charging barrel first supporting seat, and a charging barrel second supporting seat, wherein the oil cylinder is provided with an oil cylinder pressure head; the oil cylinder, the vacuum box, the charging barrel first supporting seat and the charging barrel second supporting seat are installed on a machine frame; a charging barrel is fixed between the charging barrel first supporting seat and the charging barrel second supporting seat; the oil cylinder pressure head is placed in the charging barrel; a cone-shaped pipe and a middle core needle bed are installed on the charging barrel second supporting seat; a pipe outlet nozzle is arranged on the cone-shaped pipe; a middle core needle is arranged on the middle core needle bed; and a pipe core is inserted on the middle core needle in a sleeved mode. According to the hydraulic extruding machine, the equipment structure is simple, replacement of the charging barrel and spare parts is easy, the pipe squeezing speed is flexible and adjustable, extruding force is large, a ceramic roller with a large specification can be produced, the extruded billet tube is high in density, not prone to deformation, and large in strength, and the hydraulic extruding machine is capable of meeting technical requirements of the ceramic roller produced in a cold static pressure method.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a hydraulic extruder for a ceramic roller bar blank tube. Background technique [0002] The ceramic roller rod is one of the key components in the ceramic roller kiln, which plays the role of bearing and transmission. At present, the production of ceramic rollers mainly adopts the vacuum spiral extrusion molding method, and the special equipment used is a vacuum screw extruder. The basic principle is: adopt the double helix shaft arranged up and down or the upper double helix shaft, and the lower single helix shaft; The function of the upper screw shaft is vacuum mixing and refining mud, and the function of the lower screw shaft is vacuum extrusion molding. The vacuum screw extruder can be continuously extruded, but the extrusion force is low, and the extruded billet tube is not dense enough. When extruding a large-size roller rod, the billet tube is easy to deform; in additi...
