Abstract
The utility model discloses an impact grinding cutter head with a T-shaped hard alloy protection hammer handle working surface. The impact grinding cutter head with the T-shaped hard alloy protection hammer handle working surface comprises a hammer handle body, wherein the hammer handle body is a medium carbon alloy steel hammer handle body; an abrasion-proof alloy slot is formed in the working surface of the hammer handle body; a T-shaped abrasion-proof alloy bar is brazed in the abrasion-proof alloy slot. The impact grinding cutter head with the T-shaped hard alloy protection hammer handle working surface has the advantage of prolonging the service life in a process of crushing materials; in order to further prolong the service life of the impact grinding cutter head on the original base, the material of the hammer handle is changed into the medium carbon alloy steel with good hardenability; the T-shaped abrasion-proof alloy bar is additionally arranged at the easily-abraded part of the impact grinding cutter head, so that all the working parts of the cutter head hammer handle can be protected by the hard alloy; the abrasion to the impact grinding cutter head hammer handle caused during crushing can be avoided, so that the service life of the impact grinding cutter head can be 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 T font carbide alloy protection hammer handle working face, 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 T font carbide alloy protection hammer handle working face; 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 T shape alloy bar.
The impact cutting cutter head of above-mentioned T font carbide alloy protection hammer handle working face; because antifriction alloy bar is oversize; in production, be prone to distortion; increase soldering difficulty; therefore described antifriction alloy bar 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, 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, at impact cutting cutter head, easily grind position and increase wear-resisting T shape alloy bar, make so the whole front portion of cutter head hammer handle working position 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 T font carbide alloy protection hammer handle working face 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 T shape 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 adjacent two rows' hard alloy blocks is closely arranged in the longitudinal direction.
Claims (2)
1. the impact cutting cutter head of T font carbide alloy protection hammer handle working face; 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 T shape alloy bar.
2. T font carbide alloy according to claim 1 is protected the impact cutting cutter head of hammer handle working face; 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, and adjacent two hard alloy blocks are closely arranged in the longitudinal direction.
