A clamping device for carbon electrode extruder

Abstract

A clamping device for a carbon electrode extruder, including a clamping ring and a hydraulic clamping mechanism connecting the material chamber of the carbon electrode extruder with a nozzle, the clamping ring is composed of a clamping upper ring and a clamping lower ring The hydraulic clamping mechanism includes a bracket, a hydraulic clamping cylinder, a penguin plate and a gasket block group; the bracket is connected with the material chamber of the carbon electrode extruder through bolts, and the base of the penguin plate is connected with the clamping upper ring through bolts , the top of the penguin plate is connected with the hydraulic clamping cylinder, the inner surface of the clamping ring connected with the material chamber of the carbon electrode extruder is processed with an annular trapezoidal groove, and the outer surface of the material chamber is processed with the same annular trapezoidal groove; the clamping ring on the side connected with the mouth The inner surface of the ring is processed with slotted zigzag threads, several grooves are evenly distributed along the inner circumference of the clamping ring, and the outer surface of the mouth is processed with the same zigzag threads. The beneficial effect is that the replacement of the nozzle is convenient, the time is short, the production efficiency is high, and the service life is long. The clamping and unclamping process is smooth and reliable. Can withstand large axial force.

Description

technical field [0001] The invention belongs to the technical field of forging equipment, in particular to a clamping device for a carbon electrode extrusion machine. Background technique [0002] In the prior art, the connection between the material chamber and the nozzle of the carbon electrode extruder is usually connected by a clamping ring formed by two semicircular flanges. This connection method exists: the bolts and nuts need to be disassembled to replace the spout, and because the material chamber and the spout are deformed by heat, it is difficult to disassemble, and it is necessary to use multiple auxiliary piston cylinders to work at the same time to open the clamping ring and realize the detachment of the spout and the material chamber; Due to the frequent opening and closing of the clamping ring, the life of the clamping ring is short. In order to solve this problem, in the prior art, there is a patented technology with the application number CN201410130671.X ...

This connection method exists: the bolts and nuts need to be disassembled to replace the spout, and because the material chamber and the spout are deformed by heat, it is difficult to disassemble, and it is necessary to use multiple auxiliary piston cylinders to work at the same time to open the clamping ring and realize the detachment of the spout and the material chamber; Due to the frequent opening and closing of the clamping ring, the life of the clamping ring is short

In order to solve this problem, in the prior art, there is a patented technology with the application number CN201410130671.X and the name "Nozzle Snap Ring and Carbon Extruder". This technology can realize the opening and closing of the clamping ring, but The adjustment of the clamping force of the nozzle and the rapid replacement of the nozzle cannot be realized; the production efficiency is low, the production line cannot be seamlessly connected, and the whole line cannot be automated
