AI Technical Summary

Technical Problem

The existing waste collectors for front and rear movable worktables have limited height settings, which can easily cause waste to overflow from the machine body. In addition, the waste collector is an additional device for users, resulting in high operating costs for the press.

Method used

Upper, middle, and lower hoppers are fixedly installed on the front and rear sides of the mobile workbench, forming a continuous waste material guiding and conveying channel. Through the layered opening design of the upper and middle hoppers, combined with the waste door driven by cylinders and oil cylinders, the waste material is automatically guided and collected. A detection switch is set up for dual monitoring to ensure the accurate opening and closing of the waste door and the proper locking of the latch.

Benefits of technology

It significantly improves waste collection efficiency, reduces waste ejection from the machine body, lowers the operating cost of the press, and enhances the safety and automation control precision of the mold changing process.

Abstract

A waste collection system and control method for a stamping production line, belonging to the field of press technology, is disclosed. The waste collection system includes a movable worktable. Upper hoppers are fixedly installed on the front and rear sides of the movable worktable. Below each upper hopper, a middle hopper and a lower hopper are sequentially arranged, all fixedly mounted on the base of the press. When the movable worktable is located in the die area, the upper, middle, and lower hoppers on the same side are sequentially connected for guiding and conveying waste. The upper opening of the upper hopper is lower than the table surface of the movable worktable, and the upper opening of the middle hopper is lower than the bottom of the movable worktable. When the movable worktable is working, the cooperation of the upper, middle, and lower hoppers can collect and guide waste, avoiding waste splashing. No additional waste collector is required, reducing operating costs, and the system does not affect the opening and closing of the movable worktable for die changing.
