AI Technical Summary

Technical Problem

Existing self-drilling screw forming machines have difficulty automatically removing the self-drilling screws after processing, which can easily scratch operators.

Method used

A drill tail screw forming machine including a screening component was designed. The motor drives the gear to rotate the connecting ring, causing the screening box to rotate in both directions. Waste chips fall into the slag collection box through the slag discharge hole, and the drill tail screws fall into the collection box through the outlet, realizing automatic separation and collection.

Benefits of technology

It enables the automatic separation and collection of drill bit screws and waste chips, avoiding the risk of scratches that may occur during manual operation, and improving operational safety and efficiency.

Abstract

This utility model relates to a self-drilling screw forming machine in the field of self-drilling screw processing technology. After the self-drilling screw is processed inside the processing box, the waste chips and self-drilling screw fall into the screening box under the guidance of the first guide funnel. The motor starts, causing the rotating rod to drive the gear to rotate. The gear, in conjunction with the gear ring, drives the connecting ring to rotate, causing the screening box to rotate in both directions. This facilitates the waste chips on the second baffle to fall into the slag collection box through the slag discharge hole. After the chips are discharged, the cylinder controls the annular opening and closing plate to move upward, opening multiple outlets at the same time. The screening box continues to rotate, causing the self-drilling screw on the second baffle to fall downward through the outlet. Under the limit of the first baffle, the self-drilling screw falls onto the second guide funnel and finally into the collection box. After the self-drilling screw and waste chips are screened, the second box door and the side door at the bottom of the screening box are opened, and the collection box and slag collection box can be taken out. The self-drilling screw in the collection box and the waste chips in the slag collection box are poured out.
