Abstract

The high-strength moving knife assistant knife head for the metal cutting crusher comprises a knife body, a knife head and a clamping groove, wherein the knife body is an M42 steel knife body, the clamping groove is formed in the rear end face of the knife body, a screw hole is formed in the clamping groove and communicated with the front end face of the knife body, the front end face of the knife body is an inclined plane with the left side 10-15 degrees higher than the right side, and the knife head is arranged at the upper end of the front end face of the knife body. The utility model discloses with the cutting tool bit of M42 steel manufacturing, M42 steel hardness is high, can reach 70HRC, and hot hardness is good, and high temperature hardness is high, easy cutting. The front surface of the cutter body is designed into an inclined surface, so that the cutter head forms a cutting edge, and can cut iron-based high-temperature alloy, cast high-temperature alloy, titanium alloy, ultrahigh-strength steel and the like.

Description

High-strength movable knife auxiliary tool bit for metal cutting crusher

Technical Field

The utility model relates to a metal cutting equipment instrument field, in particular to high strength metal cutter head that old and useless steel cutting rubbing crusher used.

Background

The steel scrap crusher is a crushing machine for producing crushed steel scrap, and is mainly used for processing steel bars and steel bar groups into steel bar particles, wherein the steel bar particles are the first choice of steel-smelting furnace burden of iron and steel smelting enterprises in the world. At present, the main part of the waste steel treatment is the crushing line, and the principle is that the hammer head is rotated to strike the waste steel in turn, so that the waste steel is crushed into small crushed materials. But the broken line can not process waste steel such as reinforcing steel bars, reinforcing steel bar groups and the like, and can only process large light thin materials. In addition, the cutting machines such as the gantry shears and the crocodile shears can shear waste steel, but the steel bar shearing efficiency is low, and the length specification of finished products is difficult to control by shearing messy steel bars such as steel bar groups. The tool bit of the existing scrap steel metal cutting tool is poor in wear resistance, easy to damage in the using process, capable of greatly reducing the service life of the cutting tool due to high heat generated by friction in the process of cutting metal or other hard materials, capable of increasing the burden of enterprises and capable of bringing great loss and the like to the enterprises.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems of the prior art that the prior art is not enough and has defects, and providing a high-strength movable cutter vice cutter head for a metal cutting crusher, which has simple structure, is not easy to damage and has long service life.

The technical scheme is as follows:

the high-strength moving knife assistant knife head for the metal cutting crusher comprises a knife body, a knife head and a clamping groove, wherein the knife body is an M42 steel knife body, the clamping groove is formed in the rear end face of the knife body, a screw hole is formed in the clamping groove and communicated with the front end face of the knife body, the front end face of the knife body is an inclined plane with the left side 10-15 degrees higher than the right side, and the knife head is arranged at the upper end of the front end face of the knife body.

The front end face of the cutter body can also be an inclined plane with the right side 10-15 degrees higher than the left side, and the upper end of the front end face of the cutter body is provided with a cutter head.

The utility model discloses when using, the cutter body can be installed respectively on the main epaxial vice blade disc of cutting device, and a plurality of vice tool bits are the heliciform on the main shaft and distribute, and a plurality of vice tool bits form the cutting mouth with the stationary knife head that corresponds the setting, cuts steel scrap such as reinforcing bar group in turn, and only a tool bit is the stress point during shearing, has reduced the resistance, increases pressure, has promoted cutting efficiency.

The utility model discloses with the cutting tool bit of M42 steel manufacturing, M42 steel hardness is high, can reach 70HRC, and hot hardness is good, and high temperature hardness is high, easy cutting. The front surface of the cutter body is designed into an inclined surface so that the cutter head forms a cutting edge. The utility model discloses can cut iron-based superalloy, casting superalloy, titanium alloy and super high strength steel etc. but toughness is slightly poor, and the temperature should adopt the lower limit during quenching. The crushed steel bar particles are cut, so that the technical operation is easier during smelting, the air pollution is reduced, the feeding times are reduced, the electrode damage is reduced, the heating in the furnace is uniform, and the service life of the refractory material lining in the furnace is prolonged.
