Abstract
The invention discloses an oil cylinder pipe which comprises a pipe body, wherein the pipe body is a welding pipe, and the welding pipe is one of a carbon steel welding pipe or a manganese steel welding pipe; and the welding pipe is a longitudinal welding pipe, and the oil cylinder pipe adopts the welding pipe to replace the seamless steel pipe as the pipe body. The oil cylinder pipe provided by the invention has the advantages that the cost is saved, the treatment is convenient, meanwhile, the welding pipe adopts the carbon steel welding pipe or the manganese steel welding pipe and has good wearability, and the service life of the oil cylinder pipe is prolonged.
Description
Technical field
The present invention relates to a kind of oil cylinder accessory, relate in particular to a kind of oil cylinder pipe.
Background technique
As everyone knows, the oil cylinder pipe is a kind of by a kind of high-accuracy tube material after cold-drawn or the hot rolling processing.Because precision tube inside and outside wall non-oxidation layer, bear that high-pressure non-leakage, highi degree of accuracy, high finishingness, clod wash are indeformable, enlarging, flattening free from flaw etc. a bit, so be mainly used to produce the product of pneumatic or hydraulic element, such as cylinder or oil cylinder.
Traditional oil cylinder pipe mostly adopts seamless steel pipe to be made, and exists cost of production high, the shortcoming of processing inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of oil cylinder pipe, it has the advantages that energy consumption is low, cost is low, easy to process and wear-resisting; The problem that has high energy consumption, cost height, processing inconvenience to solve traditional oil cylinder pipe.
For reaching this purpose, the present invention by the following technical solutions:
A kind of oil cylinder pipe, it comprises body, wherein, described body is welded tube.
Especially, described welded tube is any of carbon steel welded tube or manganese steel welded tube.
Especially, described welded tube is any of ERW or spiral welded pipe, and specification is: diameter 30～250 ㎜, wall thickness 3～20 ㎜.
Especially, described manganese steel welded tube is any of No. 20 manganese steel welded tubes or No. 16 manganese steel welded tubes, and tensile strength is: 350～750.
Beneficial effect of the present invention is that compared with prior art described oil cylinder pipe adopts welded tube to replace seamless steel pipe as body, has not only saved cost, and easy to process, welded tube adopts carbon steel welded tube or manganese steel welded tube simultaneously, has good wear resistance, has prolonged the working life of oil cylinder pipe.
Description of drawings
Fig. 1 is the sectional drawing of the oil cylinder pipe that provides of the specific embodiment of the invention 1.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
See also shown in Figure 1ly, Fig. 1 is the sectional drawing of the oil cylinder pipe that provides of the specific embodiment of the invention 1.
In the present embodiment, it comprises body 1 a kind of oil cylinder pipe, and described body 1 is welded tube, described welded tube is No. 20 manganese steel welded tubes, and described welded tube is ERW, and specification is: diameter 100 ㎜, wall thickness 10 ㎜, tensile strength is 500, adopts No. 20 manganese steel welded tubes to replace seamless steel pipe, and production technology is simple, manufacturing efficiency is high, cost is low, has good wear resistance, has prolonged the working life of oil cylinder pipe.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
