Abstract

The utility model relates to a metal element, belonging to an engineering machine, which is composed of a basal body 1 and a copper layer 3. The basal body 1 and the copper layer are tightly combined into integration through a diffused layer 2. The basal body is made of medium carbon steels or low-carbon steel materials. The copper layer is made of pure copper or basis brasses materials. The diffused layer is formed by that the mutual diffusion of the basal body and the copper layer forms a new metal layer. The performance of the utility model is more than 10% to 30% of a full copper element, but the cost of the utility model is only one second to one fourth of the full copper element. The utility model is an ideal engineering element.

Description

Copper-steel workpiece

At present, in the quick-wear part of engineering machinery, adopt Cu alloy material to process mostly.Because of China's copper natural resources shortage, make the copper price be higher than copper product price 3-4 doubly, therefore, influence the scope of application of copper material, only be used for irreplaceable part in the use that worm gear, cone pinion etc. locate, and from the instructions for use of member and, full copper member is not its best division, only requires the part easy to wear of member to use copper material just enough, therefore, full copper member causes a large amount of wastes of copper material, and the member cost is significantly improved.

The utility model provides a kind of copper steel hardware, and the working portion of its member adopts copper material, and remainder adopts steel, thereby reaches the service behaviour of full copper product.Both saved a large amount of copper materials, can reduce cost greatly again.

The structure of copper steel hardware of the present utility model is illustrated in conjunction with the accompanying drawings.

Fig. 1 is a cylinder copper steel hardware

Fig. 2 is a hexahedron copper steel hardware

The copper-steel workpiece structure is to be made of matrix 1, copper layer 3 as shown in Figure 1 and Figure 2, and matrix 1 and copper layer 3 become one matrix 1 and copper layer 3 strong bonded by diffusion layer 2. Its matrix 1 is medium carbon steel or low-carbon steel material, and the wide variety of shapes that consists of such as materials such as No. 45, No. 40, No. 30, No. 15, A3 is such as cuboid, cylinder, cone, annulus or rib body etc. Its copper layer 3 can be with fine copper or copper alloy Material as: tin bronze, ampco, brass etc. consist of various shapes along with the shape of matrix 1. Such as annulus, conical ring, cuboid etc. Its diffusion layer 2 is the new metal levels that mutually diffuseed to form by matrix 1 and copper layer 3, and namely this diffusion layer 2 is to contain matrix 1 and copper layer 3 two sections of material consist of.

The inventor is processed into gear, worm gear, worm screw with the cylinder copper-steel workpiece. Be processed as cone pinion with the cone copper-steel workpiece. Be processed as tooth bar with the cuboid copper-steel workpiece. Through test, installation uses service behaviour good. By detecting, its tensile strength improves 10% than former alloy, and shear-bow intensity is higher than the 10-20% of matrix 1 and copper layer 3, hardness has improved 30%, increase by more than 50 service life, uses copper-steel workpiece than full copper spare joint copper 60-80%, and cost only is original 1/2-1/4.

Copper steel hardware of the present utility model is by evidence: save a large amount of copper materials thereby service behaviour is better than Cu alloy material, cost reduces greatly, and can also satisfy a part of intensity that steel will be arranged in same parts, and another part will have the demand of the wear-resisting and toughness of copper material.Along with China's industrial or agricultural modernization, the copper steel hardware will have bright prospects in engineering machinery.
