Traveling worktable of girder hydraulic press, and control device of traveling worktable

Abstract

The invention discloses a travelling worktable of a girder hydraulic press and a control device of the travelling worktable. The travelling worktable comprises a travelling worktable body and a power system, wherein the travelling worktable body is connected with a guide rail on the girder hydraulic press; the power system is connected with the travelling worktable body; and the travelling worktable is characterized by also comprises a control system connected with the power system, and a displacement sensor for providing input signals to the control system; the power system comprises a motor and a frequency converter, wherein the frequency converter is electrically connected with the motor; the control system comprises a programmable controller and a touch screen connected with the programmable controller, and the programmable controller is electrically connected with the frequency converter; and the travelling worktable body is formed that multiple segments of metal plates are fixedly connected. The travelling worktable has the characteristic of being high in flexural strength, high in pressing precision and convenient in use.

Description

technical field [0001] The invention relates to the technical field of hydraulic machines, in particular to a mobile workbench and a control device of a longitudinal beam hydraulic machine. Background technique [0002] In recent years, with the rapid development of the manufacturing industry, automobiles, as the most important means of land transportation for human beings, have been more and more widely used. At the same time, due to the continuous improvement of people's requirements for large vehicles, the traditional longitudinal beam hydraulic presses used to process large vehicles are far from meeting the needs of high standards and mass production. [0003] As we all know, first, the flexural strength of the mobile worktable of the longitudinal beam hydraulic press is an important technical parameter. As the length of the mobile worktable of the longitudinal beam hydraulic press increases, and the width of the mobile worktable of the longitudinal beam hydraulic press ...

Problems solved by technology

[0002] In recent years, with the rapid development of the manufacturing industry, automobiles, as the most important means of land transportation for human beings, have been more and more widely used. At the same time, due to the continuous improvement of people's requirements for large vehicles, the traditional longitudinal beam hydraulic presses used to process large vehicles are far from meeting the needs of high standards and mass production.

[0003] As we all know, first, the flexural strength of the mobile worktable of the longitudinal beam hydraulic press is an important technical parameter. As the length of the mobile worktable of the longitudinal beam hydraulic press increases, and the width of the mobile worktable of the longitudinal beam hydraulic press remains unchanged, The flexural strength of the mobile workbench of the longitudinal beam hydraulic press decreases sharply, but the length of large vehicles can be increased, but the increase in the width of large vehicles is limited, so the existing longitudinal beam hydraulic presses can no longer meet people's requirements for large vehicles; 2. Traditional Most of the mobile worktables of the longitudinal beam hydraulic press are operated by human positioning, so there are defects of low machining accuracy and inconvenient operation
