Abstract
The utility model discloses an oil cylinder for a hydraulic jack, which is processed and formed by pressing method. The utility model is mainly composed of an oil cylinder body and oil cylinder mouths arranged on both ends of the oil cylinder body. The utility model is processed and formed by pressing on an inner mould and an outer mould which are arranged on a hydraulic machine by using a cold drawn seamless steel tube through the technology of material cutting, acid cleaning, phosphorization and saponification. The utility model has the advantages of low cost, high yield, high linear precision and labor saving. The utility model is suitable for oil cylinders of hydraulic jacks.
Description
The utility model relates to a kind of hydraulic jack oil cylinder.
The hydraulic jack oil cylinder that uses all is to adopt the cold rolled precision seamless steel pipe to make at present, and its shortcoming is a cold rolled precision seamless steel tube production cost height, yields poorly, cold rolled precision seamless steel pipe straightness accuracy can not guarantee, loss is big in making the oil cylinder process, and segmentation sawing speed is slow, and lost time is long.
The purpose of this utility model is at above-mentioned shortcoming, provides a kind of making easy, quality assurance, the hydraulic jack oil cylinder that adopts press process to form.
The utility model is the hydraulic jack oil cylinder, mainly being provided with cylinder ports by two ends of the cylinder body of hollow and cylinder body is formed, as material, through material cutting, pickling, phosphatization, saponification process, external mold carries out press process and forms in being provided with on hydraulic press by cold drawing seamless pipe.
The utility model compared with prior art has following remarkable advantage: the one, and cost of production is low, saves 15～20% than original technology; The 2nd, the output height improves 30% than original technology; The 3rd, can guarantee the straight line precision; The 4th, save cost of labor.The utility model is applicable to the oil cylinder of hydraulic jack.
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in the figure, the utility model is a kind of hollow tube, and mainly by hollow cylinder body 1, the two ends of described cylinder body 1 are provided with cylinder ports 2.
The utility model is applicable to the oil cylinder of hydraulic jack.
