Embodiment Construction

[0013] The laminated combined rectangular oil cylinder will be described in detail below in conjunction with the embodiments.

[0014] like figure 1 and figure 2 As shown, the shape of the oil cylinder body is rectangular, and the oil cylinder body is composed of a plurality of cylinder parts, and the cylinder parts are several cylinder structure layers 103 in the transverse direction of the oil cylinder body, each The cylinder structure layer 103 is processed separately, and the thickness of each cylinder structure layer is between 50mm and 250mm. Bolt holes and pin holes are opened on each layer of cylinder body. The cover 102 and the lower end cover 105 are connected with the cylinder structure layers 103 of each layer, and the cylinder structure layers are positioned with pins to form an integral sealed oil cylinder body.

[0015] In order to make the stress distribution everywhere on the cylinder wall of the oil cylinder block relatively uniform, the outer diameter of ...

Abstract

The invention relates to a lamination combining type rectangular oil cylinder. A cylinder body of the oil cylinder is rectangular, and the cylinder body of the oil cylinder is formed by combining a plurality of cylinder body parts. The cylinder body parts are a plurality of cylinder body structure layers on the cylinder body of the oil cylinder in the horizontal direction; While installing, all layers are laminated and combined, and an upper end cover, a lower end cover and all the cylinder body structure layers are connected together by long bolts to form an integral cylinder body of the oil cylinder. The invention solves the problems of the stress deformation generated when the oil cylinder works and other processing problems in the prior art and has more uniform stress distribution of all positions on the cylinder wall of the cylinder body of the oil cylinder, rigidity reinforcement of easy deforming part by the stress of the cylinder body of the oil cylinder and simple and durable structure.

Description

technical field [0001] The invention relates to an oil cylinder, in particular to a rectangular combined oil cylinder. Background technique [0002] In many industries such as aerospace, automobile, locomotive, military industry, building materials, heavy equipment, etc., a large number of rectangular shaped parts are required, such as automobile panels, outer skins of locomotive bodies, floor tiles in decorative materials, etc. At present, in actual production, the processing method of rectangular plates is mainly to use large-scale presses for stamping or pressing. For these formed parts, large-scale presses are generally driven by hydraulic pressure. The current hydraulic cylinders are circular hydraulic cylinders, but When processing rectangular parts, if the worktable of the press is smaller than the product to be pressed, it is easy to generate bending moment. If the pressure distributed on the plate is to be uniform, the rectangular forming part must be included in th...
