Abstract

A hammerhead with high abrasion resistance is in an integral structure comprising a hammerhead body and a hammer handle. Therefore, after one surface of the hammerhead with high abrasion resistance is abraded, the other surface of the hammerhead can be used. Moreover, four corners of the hammerhead body are respectively provided with an abrasion resistant body, and the length of each abrasion resistant body is identical with the thickness of the hammerhead body. The abrasion resistant bodies can be made of inexpensive high-speed tool steel or die steel with the hardness value of HRC (Rockwell hardness) 58-62, and other surface heat treatment methods are unchanged. The performance of the hammerhead is more than ten times of that of the prior art, and the hammerhead can be widely applied to the production industries of mining, metallurgy, cement and the like.

Description

A kind of high abrasion tup

Technical field

The utility model relates to building material industry spoil brick field crushing mechanism technical field, particularly a kind of high abrasion tup of disintegrating machine use.

Background technology

Disintegrating machine is a capital equipment in the spoil brick equipment, and tup is again the critical piece on the disintegrating machine, also is consumption maximum, the parts of easy wearing and tearing.At present, the tup of disintegrating machine is by the 50Mn casting, and be single face work, after surface heat was handled, case hardness value HRC46 heat treatment was used for degree of depth 3mm, because case hardness value HRC46 has only the inner hardness number of 3mm also to have only below the HRC38, so anti-wear performance is very poor, it is very high to change frequency, has influenced spoil brick equipment operate as normal, has improved the cost of manufacture of spoil brick.The tup of another kind of disintegrating machine, be to be welded with carbide alloy in the easy abrading section of tup body, because tup body hardness number HRC46 and carbide alloy hardness number HRC92 differ too big, anti-wear performance is also just mutually far short of what is expected with carbide alloy, causing in the course of the work, tup body serious wear carbide alloy leaks outside, it is to impact to go to sticks and staves mostly that carbide alloy is not brought into play wear-resisting effect, though anti-wear performance increases, but it is not very good, and carbide alloy is very expensive, cause significant wastage, make the making integrated cost of spoil brick improve.

The utility model content

The utility model wants the technical solution problem to be: the 50Mn casting tup of existing single structure, and single face work, surface heat are handled too shallow, and anti-wear performance is very poor.Stud with the tup of carbide alloy, tup body hardness number HRC and carbide alloy hardness number HRC differ too big, cause in the course of the work carbide alloy to leak outside to impact and go to sticks and staves the technical problem that anti-wear performance is also bad.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of high abrasion tup is tup and hammer handle integrative-structure, makes can also use other one side behind high abrasion tup one surface wear, and all is provided with wear body on four angles of tup body.The length of wear body is consistent with the tup body thickness.

Wear body can select for use cheap high-speed tool steel or mould steel hardness number HRC58-62 all can, utilize characteristics such as the high rigidity of high-speed tool steel or mould steel and high-wear resistance, sacrifice its part hardness and improve the shock resistance of wear body, impact Shi Buhui and go to sticks and staves thereby reach.Other surface heat-treatment process is constant.

The utility model with there to be technology to compare: because four angles of described a kind of high abrasion tup are provided with high-speed tool steel or mould steel wear body, high-speed tool steel or mould steel wear body hardness number HRC and tup surface hardness number HRC differ very little, and high-speed tool steel or inside and outside hardness number HRC of mould steel wear body are consistent, so anti-wear performance improves a lot, and be two sides work, be tens times so that technology to be arranged, significantly reduced the replacing number of times, improve operating efficiency, effectively reduced the making integrated cost of brick.

The specific embodiment

By a kind of high abrasion tup shown in Figure 1, tup and hammer handle integrative-structure is characterized in that: four angles of tup body (1) are provided with high-speed tool steel or mould steel cylinder wear body (2).High-speed tool steel or mould steel cylinder wear body (2) are embedded on (1) four angle of tup body.Its manufacture method can adopt casting the time to bury method underground, high-speed tool steel or mould steel cylinder wear body (2) is cut in the consistent sand mold that is embedded in (1) four angle of tup body with the tup body thickness cast.In time carry out temper behind the removing from mould and eliminate internal stress, other surface heat-treatment process is constant.

Claims

1. a high abrasion tup is characterized in that: all be provided with wear body on four angles of high abrasion tup.

2. a kind of high abrasion tup according to claim 1 is characterized in that: wear body can select for use high-speed tool steel or mould steel hardness number HRC58-62 all can.
