Abstract

The utility model introduces a composite antifriction plate, which belongs to the technical field of the container lining of a grinder and is composed of a base plate and two antifriction blocks which are respectively inlaid with the upper and the lower bottom surfaces of the base plate. The base plate and two antifriction blocks are cured through the process of electric welding or binding or casting, and therefore, the composite antifriction plate has the advantages of preferable hardness, antifriction, preferable impact toughness, simple structure, easy manufacturing process, low apparatus investment, stable product performance and high production efficiency.

Description

Antiwear composite plate

The utility model is a kind of antiwear composite plate, belongs to grinder container lining technical field.

Known antifriction board for example is used for the container lining of grinder, is stranded by the quality problems of itself always and scratches.As everyone knows, what is called is stressed the wear resistence of material, is actually the hardness of stressing material.If yet unilaterally pursue the hardness of material, the disadvantage that impact flexibility reduces can appear again, in the face of this contradiction, how to alleviate this to contradiction, become the key subjects of field of milling investigation of materials.

The purpose of this utility model, the problem that exists at the anti-friction material of this technical field of container lining of grinder especially tubular grinder just, proposing a kind of antiwear composite plate promptly provides a kind of anti-friction material of high rigidity, this material can guarantee to have simultaneously preferably again, and impact flexibility satisfies the requirement of high-quality grinding to be fit to the material or the structural needs of grinder container lining.

This antiwear composite plate of the utility model design, referring to accompanying drawing, include a laminar substrate (2), on this substrate (2), bottom surface is superimposed with wear-resistant block of material (1 of one deck respectively, 3), like this, since promptly can be used as in the bottom surface of substrate (2) abradant surface of grinder container lining increased one deck than substrate wear-resistant be the bigger material of hardness is so antiwear composite plate of the present utility model has promptly had stronger hardness, because antiwear composite plate of the present utility model is not merely to adopt anti-friction material, but at wear-resistant block of material (1,3) bottom is lined with traditional substrate (2), just a kind of newly-designed composite plate event this antiwear composite plate of the present utility model is compared with traditional lining sheet material and is both had bigger hardness, have toughness preferably again simultaneously concurrently, solved lining material better hardness and impact flexibility fish and the bear's paw preferably contradiction that can not get both for a long time effectively.

But consider between substrate and the wear-resistant block of material and simple superimposed the connection do not have good operability, in order to make substrate (2) and wear-resistant block of material (1,3) combination between is more firm and help further solidifying processing, the utility model is also with above-mentioned wear-resistant block of material (1,3) end of connection substrate (2) is designed to have dovetail (4), correspondingly, described substrate (2) connects wear-resistant block of material (1 respectively, 3) on, bottom surface has its vallecular cavity size and wear-resistant block of material (1 respectively, the dovetail groove (5) of the size coupling of dovetail 3) (4), wear-resistant block of material (1,3) promptly insert on the substrate (2) with its dovetail (4) respectively, in the dovetail groove of bottom surface (5) with substrate (2) on, bottom surface connects.

Description of drawings:

Shown in the accompanying drawing structural representation of a specific embodiment of antiwear composite plate of the present utility model,

Among the figure:

Wear-resistant block of material of 1-wear-resistant block of material 2-substrate 3-

4-dovetail 5-dovetail groove

With reference to accompanying drawing, it is substrate (2) that this embodiment adopts a rectangle cube cast iron, long 30 centimetres, wide 20 centimetres of substrate (2), thick 4 centimetres.Vertically mill out the grooved rail that its cross section is inner conical band dovetail groove (5) in upper and lower two bottom surfaces of substrate (2) respectively, 1.2 centimetres of groove depths.Cut two its sizes and the big or small wear-resistant block of material of high-strength alloy (1,3) that mates of substrate (2), expect long 30 centimetres, wide 20 centimetres for wear-resistant.Respectively a side bottom surface of wear-resistant block of material (1,3) is vertically milled and make its size and the big or small dovetail (4) that mates of the grooved rail inner chamber of the inner conical band dovetail groove (5) of aforesaid substrate (2).Respectively the wear-resistant block of material (1,3) of the above-mentioned band dovetail (4) that processes vertically inserted in the dovetail groove of substrate (2) superimposedly by its dovetail (4), then its seam is given electric welding and reinforce with substrate (2).Can make it to solidify the formation one by methods such as bonding or type castings in addition.

The antiwear composite plate that makes therefrom is proved to be respond well through manufacturing experimently to try out, has original, simple in structure, the handling ease of design, be convenient to dismounting, maintenance, positive and negative exchange, working face hardness height, wear resistence well have simultaneously the characteristics of impact flexibility preferably again, especially try out when cartridge type annular grinder liner, effect is more obvious, and its impact flexibility is worked energetically 15 joules/square centimeter after testing, and the high network cast iron sheet material system liner that the abrasion resistance ratio is commonly used improves more than three times.And properties of product are stable, and equipment investment is again little, makes production efficiency greatly improve.

Claims

1, a kind of antiwear composite plate, it includes a laminar substrate (2), it is characterized in that the upper and lower bottom surface of described substrate (2) is superimposed with wear-resistant block of material of one deck (1,3) respectively.

2, antiwear composite plate according to claim 1, an end that it is characterized in that described wear-resistant block of material (1,3) connection substrate (2) has dovetail (4), correspondingly, the upper and lower bottom surface that described substrate (2) connects wear-resistant block of material (1,3) respectively has the dovetail groove (5) of its vallecular cavity size and the size coupling of the dovetail (4) of wear-resistant block of material (1,3) respectively, and wear-resistant block of material (1,3) promptly is connected with the upper and lower bottom surface of substrate (2) in the dovetail groove with the upper and lower bottom surface of its dovetail (4) insertion substrate (2) respectively.
