Abstract

The utility model relates to an impact bearing anvil embedded and cast with antifriction alloy, which is fabricated through casting. The impact bearing anvil is characterized in that hard alloy is embedded and cast on the working surface of the impact bearing anvil. The impact bearing anvil has the advantages of high tenacity and strength, wearable surface, easy manufacture, small volume and long service life.

Description

Anvil is hit in holding of a kind of castingin antifriction alloy

Technical field

The utility model relates to the disintegrating apparatus of medium hardness brittle material, particularly relates to a kind of holding of castingin antifriction alloy 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, the raw ore that the stone pit can the be shipped-inferior granularity that needs into mill that is crushed to.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, in the world wide institute of each hammer mill specialized company generally employing be that holding of big section hit anvil, the wearing layer built-up welding is carried out on the surface, its shortcoming is: 1. the requirement height of pair material; 2. heat treatment requirements height; 3. maintenance cost height (in the use want frequent built-up welding).

Summary of the invention

The holding of castingin antifriction alloy that the utility model provides a kind of high tenacity and intensity, surface abrasion resistance for solving the technical problem that exists in the known technology, makes easily, volume is little and the life-span is long hit anvil.

The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: anvil is hit in holding of a kind of castingin antifriction alloy, is that casting forms, and is characterized in that described holding hit anvil working face castingin carbide alloy is arranged.

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

Anvil is hit in holding of above-mentioned a kind of castingin antifriction alloy, is characterized in described and holds that to hit the anvil material be carbon steel or potassium steel.

Advantage and the good effect that the utlity model has are: 1, holding of castingin antifriction alloy hit anvil, because its material has adopted the carbon steel or the potassium steel of higher toughness, and working face has adopted carbide alloy---carbon steel or potassium steel castingin bimetallic material, make it become the whole composite members that has two kinds of material characteristics concurrently, both can bear the big moment of flexure of bringing 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, this to hold and hit the anvil wear surface be the working face imbedding hard alloy, its life-span improves greatly, be holding of current use hit the anvil life-span 2-4 doubly, reduced the workload of on-the-spot frequent built-up welding.3, this to hold the base material that hits anvil be carbon steel or potassium steel, have good toughness and intensity, can bear fierce impact continuously, low price; 4, owing to be light section formula structure, heat treatment is simple and convenient, and quenching degree is good, has reduced the casting flaw probability, processes easily and installs.

Description of drawings

Fig. 1 is that holding of castingin antifriction alloy hit the anvil outline drawing;

Fig. 2 is the profile of Fig. 1.

Label among the figure is respectively: 1A holds to hit the anvil working face, and 1B is a carbide alloy.

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, hit anvil working face 1A imbedding hard alloy 1B holding, holding and hitting the anvil material is carbon steel or potassium steel.During manufacturing, at first put into inserting of antifriction alloy at the die cavity corresponding site, in die cavity, pour into a mould carbon steel or manganese steel mother liquor then with excellent toughness, by the strong heat effect of mother liquor, making inserts is in the counterdiffusion mutually of the concurrent bioelement of semi-molten state in the regular hour with the interface of mother liquor contact, after the condensation, insert and the firm melting welding of mother metal is one.It is more easy to control to hold the surface quality of hitting anvil, and technical process is simple, need not increase new equipment, just can produce under general casting condition.

Operating principle of the present utility model is, the centre that anvil is positioned at two rotors and discharge grate is hit in holding of castingin antifriction alloy, material greater than gap between rotor and the double-edged fine-toothed comb is intercepted on its working face, the tup 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

1, holding of a kind of castingin antifriction alloy hit anvil, is that casting forms, and it is characterized in that: described holding hit anvil working face castingin carbide alloy is arranged.

2, holding of a kind of castingin antifriction alloy according to claim 1 hit anvil, it is characterized in that: describedly hold that to hit the anvil material be carbon steel or potassium steel.
