Hydraulic machine provided with automatic-sensing safety protection device

Abstract

The invention discloses a hydraulic machine provided with an automatic-sensing safety protection device. The hydraulic machine comprises a base plate, upright posts and a top plate; the upright postsare fixedly installed at the two sides of the upper surface of the base plate; the top plate is fixedly connected between the top ends of the two upright posts; a hydraulic cylinder is fixedly installed at the middle part of the top end of the top plate; the end part of the hydraulic cylinder is fixedly connected with a hydraulic rod after penetrating through the top plate; and one end of the hydraulic rod is fixedly connected with a supporting plate. According to the hydraulic machine disclosed by the invention, the middle part of the bottom end of the supporting plate is provided with a fixed base; the fixed base is internally provided with a sliding chamber; a limiting plate, a spring and a connecting column are arranged inside the sliding chamber; a good shock absorption and bufferingeffect is achieved; when the telescopic hydraulic rod is driven to move downwards by the hydraulic cylinder, the limiting plate slides inside the sliding chamber so as to extrude the spring so that apressing plate can achieve a certain buffering effect, thus the pressing plate can achieve a buffering and shock absorption effect on a workpiece which is machined on a worktable; by arranging a shockabsorbing mechanism at the bottom end of the worktable, the vibration, generated by the pressing plate, of the worktable can be effectively reduced; and the stability is improved.

Description

technical field [0001] The invention relates to a hydraulic press device, in particular to a hydraulic press with an automatic induction safety protection device, which belongs to the technical field of machinery. Background technique [0002] A hydraulic press is a machine that utilizes hydrostatic pressure, uses liquid as the working medium, and uses Pascal's principle to transfer energy to process metal, plastic, rubber, wood, powder and other products. [0003] However, when the current hydraulic machine is working, the pressure plate is in rigid contact with the workbench when it is rolled. For processing parts of different materials, it is easy to damage the workpiece, and the shock absorption effect is not good. Moreover, the existing hydraulic machine does not have safety protection devices. It often causes safety accidents. Contents of the invention [0004] The invention provides a hydraulic press with an automatic induction safety protection device, which is us...
