Problems solved by technology

[0002] The hydraulic cylinder is the working and executive element in the hydraulic system. People manufacture various hydraulic cylinders according to actual needs. Among them, the double-rod hydraulic cylinder has been widely used in many industries, but the two existing double-rod hydraulic cylinders The piston rod generally protrudes left and right, or cannot be controlled separately when protruding from the same end. In some special occasions, it is necessary to lock the workpiece first. This process requires slow pressure from the hydraulic cylinder. After locking, the workpiece is locked. For stamping, it is necessary to quickly stamp at this time, which requires separate control of the piston rod to meet production requirements

Abstract

The invention provides a hydraulic oil cylinder. The hydraulic oil cylinder comprises a hydraulic cylinder body, a piston and a piston rod, wherein the hydraulic cylinder body is provided with two cavities, the two cavities are a first cylinder body and a second cylinder body respectively, the piston comprises a first piston and a second piston, the piston rod comprises a first piston rod and a second piston rod, and the first piston and the first piston rod are located in the first cylinder body, the second piston and the second piston rod are located in the second cylinder body, a through hole is formed in the axial direction of the second piston rod, the first piston rod penetrates through the through hole of the second piston rod, the first cylinder body and the second cylinder body are combined into a complete hydraulic cylinder body, different action requirements can be controlled respectively, the second piston rod of the second cylinder body realizes the working locking action,and the first piston rod of the first cylinder body realizes the stamping workpiece action. The hydraulic oil cylinder has the beneficial effect that the structure is compact, the assembly is simple,the maintenance are convenient, and the structural problem is solved for hydraulic intelligent control.

Description

technical field [0001] The invention relates to the technical field of oil cylinders, in particular to a hydraulic oil cylinder. Background technique [0002] The hydraulic cylinder is the working and executive element in the hydraulic system. People manufacture various hydraulic cylinders according to actual needs. Among them, the double-rod hydraulic cylinder has been widely used in many industries, but the two existing double-rod hydraulic cylinders The piston rod generally protrudes left and right, or cannot be controlled separately when protruding from the same end. In some special occasions, it is necessary to lock the workpiece first. This process requires slow pressure from the hydraulic cylinder. After locking, the workpiece is locked. Stamping, at this time, it needs to be stamped quickly, which requires separate control of the piston rod to meet the production requirements. Contents of the invention [0003] In order to overcome the problems existing in the pri...
