Manual hydraulic press with adjustable height

Abstract

The invention discloses a manual hydraulic press with adjustable height, comprising a frame, a hydraulic cylinder, a piston rod, a lifting platform, pull rings, pull springs, a presser rod, and a workbench. The frame is composed of a base, vertical rods, transverse rods, oblique rods and a cross beam, each side of the base is provided with one vertical rod, the transverse rods are connected to thetops of the two vertical rods, the top of each of the front and rear of the vertical rods is provided with one oblique rod, and the cross beam is arranged between the tops of the oblique rods; the piston rod is fixed to the bottom center of the cross beam; the hydraulic cylinder sleeves the bottom of the piston rod; the lifting platform is arranged at the bottom of the hydraulic cylinder; a bearing block is arranged on the lifting platform; the hydraulic cylinder is fixed to the lifting platform via the bearing block; each side of the lifting platform is provided with one pull ring in penetrating manner; one pull spring is hung to the top of each pull ring; the presser rod is fixedly welded to the bottom of the lifting platform; the workbench is arranged below the presser rod. The manualhydraulic press allows the height of the workbench to be adjusted and fixed, the piston rod can be manually extended and can be reset, and good safety and reliability are provided.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical manufacturing, in particular to the technical field of a height-adjustable manual hydraulic press. 【Background technique】 [0002] A hydraulic press is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing processes and pressing forming processes, such as forging, stamping, flanging, etc. The hydraulic press is driven by the hydraulic cylinder to work the hydraulic actuator. However, when the hydraulic press is used in different occasions, its flexibility requirements are higher. Most of the hydraulic presses are very rigid, not only inconvenient to move, but also unable to adjust according to the actual situation. It is necessary to adjust the height of the workbench reasonably, which cannot be well suited to the actual needs of the work. 【Content of invention】 [0003] The purpose of the present invention...

Problems solved by technology

The hydraulic press is driven by the hydraulic cylinder to work the hydraulic actuator. However, when the hydraulic press is used in different occasions, its flexibility requirements are higher. Most of the hydraulic presses are very rigid, not only inconvenient to move, but also unable to adjust according to the actual situation. The height of the workbench needs to be adjusted reasonably, which cannot be well suited to the actual needs of the work
