The invention discloses a three-material composite welding plate hammer and a preparing method thereof. The three-material composite welding plate hammer is formed by sequential welding of an upper wear-resisting block, a middle low alloy steel layer and a lower wear-resisting block, the upper wear-resisting block (1) and the lower wear-resisting block are each composed of a hard alloy block, a high-chromium iron layer and a low alloy steel layer, the inner sides of the high-chromium iron layers and the low alloy steel layers are compounded, and hard alloy blocks are embedded on the two sides of each high-chromium iron layer. The dual liquid metal composite casting technology, the imbedding technology and the welding technology are applied to the same casting, the service life of the hammer is obviously prolonged, the plate hammer structure is designed strictly according to the wear portion, the use amount of alloy is reduced, the cost is reduced, and the cost performance is improved; the welding technology of preheating multi-pass welding and the like is used, and the dual-metal composite interface stability is ensured.
Description
Technical field
The present invention relates to the preparation field of material, and in particular to a kind of three materials composite welding bar and preparation method thereof.
Background technology
Bar is parts important in impact breaker.During machine operation, bar is driven by motor, and material is thrown
To beating lining plate, realize crushing, then material bounces back into bar active region from beating lining plate again, realizes second-time breakage, this mistake
Journey repeats, and descending one, two, three back cavities that enter of material repeat to crush, until material is crushed to required grain
Degree, is discharged by discharging opening.Bar is subjected to substantial amounts of abrasive wear in disintegrating machine, and is impacted by certain load
Power, common single material bar is difficult to while meeting this severe operating mode.Domestic application rich chromium cast iron bar the most stable,
Bulk materials are run into, the problems such as rupturing often occurs, damage machine.From machine principle Analysis, have near bar both sides material
Aggregation situation, abrasion is more serious, and bar middle part is taken second place.
The content of the invention
To solve the above problems, the invention provides a kind of three materials composite welding bar and preparation method thereof.
For achieving the above object, the technical scheme taken of the present invention is：
A kind of three material composite welding bars, welded successively by upper wear-resistant block, middle part low-alloy steel layer and lower wear-resistant block and

The depth of assembling groove is 30-40mm, and upper wear-resistant block and lower wear-resistant block are by hard alloy blocks, high chromium cast iron layer and low-alloy
Steel layer is constituted, and the high chromium cast iron layer inner side is combined with low-alloy steel layer, and high chromium cast iron layer both sides are inlaid with hard alloy blocks.
Preferably, the size of the hard alloy blocks is 30mm × 50mm × 200mm, and low-alloy steel thickness degree is not less than
40mm。
Present invention also offers a kind of preparation method of three materials composite welding bar, comprises the steps：
S1, first prefabricated hard alloy blocks, recycle double-fluid double metal composite casting technology and castingin technology by low-alloy steel
It is compound with rich chromium cast iron, at the same the rich chromium cast iron part of bar both sides be bumped into hard alloy blocks complete wear-resistant block and under it is wear-resisting
The preparation of block；
S2, prefabricated middle part low-alloy steel layer, upper wear-resistant block, middle part low-alloy steel layer, lower wear-resistant block are welded to connect successively
Together, three material composite welding bars are obtained final product.
Preferably, step S2 adopts multinomial solder technology.
Preferably, the multinomial solder technology at least includes preheating step and multi-pass welding welding step.
The invention has the advantages that：
1. propose biliquid metal composite foundry engieering, castingin technology, solder technology, apply in same foundry goods, significantly
Improve the service life of product.
2. board hammer structure is designed in strict accordance with abrading section, save alloy usage amount, reduce cost, improve sexual valence
Than.
3. using welding procedures such as preheating multi-pass weldings, it is ensured that bimetallic compound interface stability.
