Quick dismounting device for clamping ring of model nozzle of carbon extruding machine

Abstract

The invention discloses a carbon extruding machine nozzle clamping ring quick dismounting device which comprises a boss arranged in the middle of the outer side of each half clamping ring, and four concave holes are machined in each boss. The top cylinder comprises a cylinder body and a cylinder bottom which are connected with each other, a first end part, far away from the cylinder bottom, of the cylinder body is of a four-petal convex circular structure, a first through hole is formed in the center of the first end part, a second end part, close to the cylinder bottom, of the cylinder body is of a square cross section, and the four-petal convex circular structure of the first end part is matched with the four-petal concave hole of the boss; a piston is installed in the cylinder body, a rod portion of the piston is inserted into the first through hole of the first end portion, and a spring is installed between the periphery of the rod portion of the piston and the cylinder body. According to the quick dismounting device for the model nozzle clamping ring of the carbon extruding machine, the technical defects that in the prior art, a sealing piece is prone to aging, and oil leakage hidden danger is increased are overcome, the technology that in the prior art, four piston cylinder structures are distributed at the four corners is abandoned, the structure is simple, and the model nozzle clamping ring is convenient and easy to dismount.

Description

technical field [0001] The invention belongs to the technical field of auxiliary devices of a carbon extruder, and in particular relates to a quick disassembly device for a snap ring of a carbon extruder. Background technique [0002] The carbon extruder is used to extrude carbon paste into electrode products. The carbon extruder has a material chamber and a nozzle connected to one end of the material chamber for discharging. The nozzle and the material chamber are connected and fixed by the nozzle snap ring. The nozzle is the molding die of the carbon extruder, and the carbon paste is extruded through the nozzle. When producing electrode products of different specifications, it is necessary to replace the nozzles of different specifications. [0003] When replacing the nozzle, it is necessary to remove and install the nozzle snap ring. Chinese patent application 201410130671.X discloses a carbon extrusion machine mouth snap ring replacement device, in which four oil cylin...

AI Technical Summary

Problems solved by technology

[0004] However, the problems in the above-mentioned prior art include: 1. The oil cylinder is arranged at the four corners of the snap ring, the specification of the oil cylinder is small, and the push-off force is small; 2. Four planes (notches) need to be processed on the flange of the nozzle, which weakens The strength of the nozzle parts; 3. The oil cylinder is always (including during production) installed on the snap ring, and the seal is easy to age when heated, and at the same time increases the hidden danger of oil leakage
