Abstract
The utility model discloses a high-wear-resistant impacting and breaking knife head with a high-wear-resistant hammer handle brazed by a hard alloy. The impacting and breaking knife head comprises a hammer handle body, wherein the hammer handle body is made of medium-carbon alloy steel; a wear-resistant alloy groove is arranged on a working surface of the hammer handle body; and a wear-resistant alloy strip is brazed in the wear-resistant alloy groove and is an L-shaped alloy strip. The high-wear-resistant impacting and breaking knife head disclosed by the utility model has the advantages that the service life of the impacting and breaking knife head can be prolonged in the breaking process; on the original basis, in order to prolong the service life of the impacting and breaking knife head, the type of the material of the hammer handle is changed into the medium-carbon alloy steel with good hardenability, and simultaneously the wear-resistant L-shaped alloy strip is added at the easily-worn part of the impacting and breaking knife head, so that the front half part of the working part of the hammer handle of the knife head is also in the protection range of the hard alloy and is used for preventing broken materials from wearing the hammer handle of the impacting and breaking knife head, and further the service life of the impacting and breaking knife head is greatly prolonged.
Description
Technical field
The utility model patent relates to a kind of impact crusher and rotor, particularly a kind of high abrasion compound tool bit using on impact crusher.
Background technology
The cutter head using on existing impact grinding machine rotor, major part is to use mild steel, low-carbon alloy steel to produce the hammer handle of cutter head, for hammer handle position is applicable to channeling, hammer handle is all generally to take annealing or normalized treatment, then dig the bonding groove of alloy bar, stick with glue alloy bar and use, under the powerful pinch shock of institute's broken material, impact cutting cutter head is wear out failure very easily.Because carbide alloy is only in impact cutting cutter head working face middle part; make like this carbide alloy liquidate to break up the high abrading section before cutter head working face alloy there is no protective effect; impact cutting cutter head in use; because hammer handle position hardness before impact cutting cutter head working face alloy is low; and be the carbide alloy of vertical bar shaped, not wear-resistant, wear away soon; make alloy exposed and come off, thereby whole impact cutting cutter head was lost efficacy.
Utility model content
The purpose of this utility model is in order to overcome above-mentioned defect, provides a kind of impact cutting cutter head of high abrasion material hammer handle brazing hard alloy, the service life that can improve impact cutting cutter head.
For achieving the above object, the utility model is by the following technical solutions:
A kind of impact cutting cutter head of high abrasion material hammer handle brazing hard alloy, comprise hammer handle body, hammer handle body is medium carbon alloy steel hammer handle body, is provided with antifriction alloy groove on the working face of hammer handle body, in antifriction alloy groove, soldering has antifriction alloy bar, and antifriction alloy bar is L shaped alloy bar.
The impact cutting cutter head of above-mentioned high abrasion material hammer handle brazing hard alloy, because antifriction alloy bar is oversize, in production, be prone to distortion, increase soldering difficulty, therefore described antifriction alloy bar is to consist of the combination of polylith hard alloy blocks, and isometric with hammer handle body, the length L of every hard alloy blocks is 50mm, width d is 12mm, and thickness h is 10mm, and adjacent two rows' hard alloy blocks is closely arranged in the longitudinal direction.
Adopt technique scheme, the utility model has following advantage: the utlity model has and make material in shattering process, can improve the impact cutting cutter head advantage in service life, the utility model on former basis in order further to improve the service life of impact cutting cutter head, change the hammer handle material trade mark into medium carbon alloy steel that quenching degree is good, simultaneously, at impact cutting cutter head, easily grind position and increase wear-resisting L shaped alloy bar, make like this first half of cutter head hammer handle working position also within the protection domain of carbide alloy, the wearing and tearing of breaking up cutter head hammer handle place for stoping broken material to liquidate, thereby greatly extended the service life of impact cutting cutter head.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
The impact cutting cutter head of a kind of high abrasion material hammer handle brazing hard alloy as depicted in figs. 1 and 2, comprise hammer handle body 1, hammer handle body is medium carbon alloy steel hammer handle body, on the working face of hammer handle body, be provided with antifriction alloy groove, in antifriction alloy groove, soldering has antifriction alloy bar 2, and antifriction alloy bar is L shaped alloy bar.
Because antifriction alloy bar is oversize, in production, be prone to distortion, increase soldering difficulty, therefore described antifriction alloy bar 2 is in conjunction with forming by polylith hard alloy blocks, and isometric with hammer handle body, the length L of every hard alloy blocks is 50mm, and width d is 12mm, thickness h is 10mm, and adjacent two rows' hard alloy blocks is closely arranged in the longitudinal direction.
Claims (2)
1. the impact cutting cutter head of a high abrasion material hammer handle brazing hard alloy, comprise hammer handle body (1), it is characterized in that: hammer handle body is medium carbon alloy steel hammer handle body, on the working face of hammer handle body, be provided with antifriction alloy groove, in antifriction alloy groove, soldering has antifriction alloy bar (2), and antifriction alloy bar is L shaped alloy bar.
2. the impact cutting cutter head of high abrasion material hammer handle brazing hard alloy according to claim 1, it is characterized in that: described antifriction alloy bar (2) is in conjunction with forming by polylith hard alloy blocks, and isometric with hammer handle body, the length L of every hard alloy blocks is 50mm, width d is 12mm, thickness h is 10mm, and adjacent two hard alloy blocks are closely arranged in the longitudinal direction.
