Positioning device and metal plate automatic production line

Abstract

The invention relates to a positioning device and a metal plate automatic production line. The positioning device is used for a production line die and the production line die includes an upper die and a lower die. The upper die and the lower die act jointly, to complete stamping on a workpiece on the lower die. The positioning device includes a driving block and a sliding block. The driving blockis fixedly connected with the upper die, the sliding block is movably connected to the lower die, the driving block is driven by the upper die to move and drives the sliding block to slide on the lower die, and the sliding block pushes the workpiece to move on the lower die, to adjust the position of the workpiece. The positioning device has the advantages of being reasonable in design, simple instructure and low in cost and capable of automatically correcting the workpiece on the lower die to make the position of the workpiece accurate and ensure metal plate stamping quality.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a positioning device and an automatic sheet metal production line. Background technique [0002] In the current automatic processing of sheet metal stamping, it is necessary to accurately position the workpiece. Some workpieces require relatively high processing and positioning accuracy, and the general error is ±0.05mm. The production method adopts the manipulator to grab the material workpiece from the upper station mold or wool stack and put it into the lower station mold. Usually the lower station mold adopts the fixed positioning method of four-side positioning. When the manipulator grasps the workpiece from the upper station to the lower station, the manipulator brakes suddenly after high-speed movement. Due to inertia, the position of the manipulator for discharging materials often has deviations. When the processing workshop speeds up the production temp...

AI Technical Summary

Problems solved by technology

When the processing workshop speeds up the production tempo of the automatic line in order to improve production efficiency, the inertia of the beam that drives the manipulator movement will also increase, resulting in a large deviation in the discharging position

At the same time, the automatic line works for a long time, and the gear and rack of the transmission parts of the automatic line will be worn to varying degrees. When the wear gap of the transmission parts of the automatic line is too large, there will be a large deviation in the position where the manipulator puts the workpiece into the mold. Multiple adjustments to automatic line molds

In addition, if the blanking size is too large or too small, the way the automatic line manipulator grabs the material will also affect the feeding position of the automatic line, resulting in the problem that the workpiece cannot be positioned close to the processing, which will cause the workpiece to be scrapped after stamping, affecting the production efficiency of the automatic line. Increased processing and production costs
