Abstract

The utility model relates to a new style beat bearing anvil, is produced through casting, the utility model is characterized in that the beat bearing anvil is hollow. The utility model has advantages that the heat treatment is simple and convenient, the hardness penetration is good, the beat bearing anvil possesses good toughness and high strength, and the manufacturing cost is reduced.

Description

A kind of novel holding hit anvil

Technical field

The utility model relates to the disintegrating apparatus of medium hardness brittle material, particularly relates to a kind of novel holding that is used on the birotor single hop hammer mill and hits anvil.

Background technology

Birotor single hop hammer mill is a kind of disintegrating machine of large reduction ratio, is mainly used in the fragmentation of cement producting material, and the raw ore primary fragmentation that the stone pit can be shipped is to going into the granularity that mill needs.In order to make that raw material energy quilt is broken fully and prevent bulk materials leakage and equalization shunting, in the middle of impact breaker, be provided with unsettled holding and hit anvil.Raw material is fallen to hold after by primary fragmentation and is hit on the anvil in crusher chamber, but the tup that is subjected to the full circle swinging on the high speed rotor rotated impacts fragmentation continuously, can be divided to separately double-edged fine-toothed comb zone up to the granularity of fragmentation.Unsettled holding hit anvil and afforded very big moment of flexure owing to being violently shaken, be subjected to when shunting simultaneously violent wash away and denuding, so hold and hit anvil and must be able to bear very big moment of flexure and promptly have intensity and toughness preferably, have higher surface hardness simultaneously and adapt to violent washing away.At present, and each hammer mill specialized company of Europe (as the KRUPP of Germany, KHD and O﹠amp; K company) what generally adopt is that anvil is hit in solid the holding of big section, its shortcoming is: 1. casting flaw appears in big section easily; 2. be not easy heat treatment (easily split, quenching degree is poor); 3. to the requirement height of material; 4. weight is big.

Summary of the invention

The utility model provides a kind of heat treatment simple and convenient for solving the technical problem that exists in the known technology, toughness and intensity height, surface abrasion resistance, make easily, volume is little and the life-span is long novel holding hit anvil.

The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of novel holding hit anvil, is that casting forms, and is characterized in described and holds that to hit anvil inside be hollow out.

The utility model can also adopt following technical measures to realize:

Above-mentioned a kind of novel holding hit anvil, is characterized in that the described material that hits anvil that holds is high manganese cast steel or steel alloy cast steel.

Advantage and the good effect that the utlity model has are: 1, hollow out is held and is hit anvil toughness and intensity height, both can bear the big moment of flexure of being brought by irregular continuous fierce impact and can satisfy by the requirement of acutely washing away a large amount of wearing and tearing that bring; 2, owing to be light section hollow out formula structure, heat treatment is simple and convenient, and quenching degree is good, prolongs greatly service life and significantly reduced to hold the volume and weight that hits anvil, has reduced the casting flaw probability, processes easily and installs; 3, can select the manufacturing of high manganese cast steel material for use, make and hold the problems such as material, manufacturing and heat treatment of hitting anvil and can be resolved, greatly reduce cost in China.

Description of drawings

Fig. 1 is that novel holding hit the anvil outline drawing;

Fig. 2 is the profile of Fig. 1;

Fig. 3 holds to hit the anvil fundamental diagram.

Label among the figure is respectively: 1A holds to hit the anvil head, and 1B is the anvil body portion of hitting of holding, and 1C holds to hit the anvil hollow-out parts, and the 1st, hollow out is held and is hit anvil, and the 2nd, double-edged fine-toothed comb, the 3rd, tup, the 4th, material, the 5th, rotor.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, be cast with regularly arranged hole between the anvil body 1B of portion and promptly hold and hit anvil hollow-out parts 1C holding to hit anvil head 1A and hold to hit.

Operating principle of the present utility model is, see also Fig. 3, hollow out is held and is hit the centre that anvil 1 is positioned at two rotors 5 and double-edged fine-toothed comb 2, material 4 greater than gap between rotor and the double-edged fine-toothed comb is blocked in the above, the tup 3 that is had very big kinetic energy continues to hit broken, can enter double-edged fine-toothed comb when zone up to particle size after cracking, be held and hit anvil and be diverted to separately double-edged fine-toothed comb zone.

Claims (2)

1, a kind of novel holding hit anvil, is that casting forms, and it is characterized in that describedly holding that to hit anvil inside be hollow out.

2, a kind of novel holding according to claim 1 hit anvil, it is characterized in that: the described material that hits anvil that holds is high manganese cast steel or steel alloy cast steel.
