Abstract
The utility model discloses a wear-resistant cold-drawing seamless steel tube for an oil cylinder body. The wear-resistant cold-drawing seamless steel tube comprises a tube body, wherein the tube body is manufactured according to a cold-drawing process, and a wear-resistant layer which is formed during extruding and drawing of the inner wall of the tube body by a cold-drawing machine is arranged on the inner wall of the tube body. The wear-resistant cold-drawing seamless steel tube is simple in structure, good in wear resistance and long in service life of the steel tube.
Description
Technical field
The utility model relates to the metallic material technical field, the wear-resisting cold drawing seamless pipe of especially a kind of cylinder block.
Background technique
Oil cylinder can rub to inboard wall of cylinder block in the course of the work, and the seamless steel pipe internal wall wear resistance is had higher requirements.Common seamless steel pipe internal wall does not pass through special Wear-resistant Treatment, and inwall can not reach wear-resisting requirement and easily wear and tear, thereby causes oil cylinder shortening in working life.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of inwall wear resistance good, the wear-resisting cold drawing seamless pipe of the cylinder block of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: the wear-resisting cold drawing seamless pipe of a kind of cylinder block, comprise the body that adopts cold-drawing technology to be made, inboard wall of tube body has the wearing layer that forms in to inboard wall of tube body extruding process of tube plug drawing mill at drawbench.
Further, wearing layer thickness is 0.02～0.06mm.
The beneficial effects of the utility model are: the cylinder block that the utility model provides is simple in structure with wear-resisting cold drawing seamless pipe, and steel pipe inner wall has wearing layer, and the inwall wear resistance is good, long service life.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. bodys, 2. wearing layers among the figure
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
The wear-resisting cold drawing seamless pipe of a kind of cylinder block as shown in Figure 1 comprises the body 1 that adopts cold-drawing technology to be made, and body 1 inwall has the wearing layer 2 that forms in to body 1 inwall extruding process of tube plug drawing mill at drawbench.Wearing layer 2 thickness are 0.04mm.Wearing layer 2 compact structures have higher wear resistance.
Use the cold drawing seamless pipe that has wearing layer 2 on body 1 inwall to make cylinder block, the inboard wall of cylinder block wear resistance is high, can avoid occuring inboard wall of cylinder block causes oil cylinder shortening in working life because of excessive wear situation.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (2)
