Movable workbench decelerating and stopping limiting device used in mechanical press machine

Abstract

The invention discloses a movable workbench decelerating and stopping limiting device used in a mechanical press machine. The movable workbench decelerating and stopping limiting device comprises a movable workbench. A detection block is arranged on a guide rail below the movable workbench. A support is arranged on the upper surface of the movable workbench through a screw. A travel switch is arranged on the right side of the front face of the support, and a vertical shaft is inserted and connected in a transverse plate on the top of the support. The bottom end of the vertical shaft sequentially penetrates the support and the movable workbench and makes contact with the upper surface of the detection block, and a concave part is reserved in the middle portion of the vertical shaft. According to the movable workbench decelerating and stopping limiting device used in the mechanical press machine, when the movable workbench departs in place, the detection block on the guide rail makes contact with the bottom end of the vertical shaft and jacks the vertical shaft, the lower half part of the vertical shaft makes contact with the travel switch, and accordingly the movable workbench can be accurately decelerated and stopped; and when the vertical shaft is separated from the detection block, the vertical shaft downwards moves under the action of a compression spring, the vertical shaftis separated from the travel switch and resets, and operation is relatively simple.

Description

Technical field [0001] The invention relates to the technical field of presses, in particular to a deceleration and stop limit device for a mobile worktable used by a mechanical press. Background technique [0002] Mechanical press is a kind of general forging equipment, which is used in major automobile and household appliances industries. As the working carrier of the mechanical press, the worktable is a basic part of the mechanical press. Nowadays, there are more and more types of molds. Under the premise of improving production efficiency, the convenience and speed of changing molds are particularly important. Under this premise, mobile workbenches and multiple mobile workbenches at the same time have become common users Demand. When moving the workbench to replace the mold, it needs to decelerate and stop accurately. How to ensure the accuracy of deceleration and stop is the problem to be solved by the present invention. Summary of the invention [0003] (1) Technical prob...
