AI Technical Summary

Technical Problem

Existing cold heading forming equipment suffers from low efficiency in the billet feeding stage, resulting in increased idle time and limited billet supply per unit time. This makes it difficult to match the high-speed processing capacity of the cold heading forming machine, affecting the production line's capacity improvement. Furthermore, frequent feeding exacerbates equipment wear and tear, increasing maintenance frequency and costs.

Method used

Adopting a continuous conveying and step-by-step forming design, the feeding roller and conveying roller work together, combined with multi-stage rolling pressure from inclined bending roller, U-shaped inner frame and forming roller, to achieve stable feeding and precise forming of sheet metal. With the coordinated operation of the stamping and cutting components, continuous processing of fasteners is ensured.

Benefits of technology

It increased productivity per unit time, reduced equipment wear and tear, lowered maintenance costs, and ensured production continuity and consistent molding quality.

Abstract

This disclosure relates to the technical field of guardrail fastener processing equipment. One embodiment of this disclosure provides a cold heading forming device for guardrail fasteners, comprising: an equipment base and a forming frame, the forming frame being fixed to the surface of the equipment base, a feeding frame being fixed to the surface of the equipment base, a feeding forming assembly being disposed on the feeding frame and the forming frame, and a stamping and cutting assembly being disposed on the surface of the forming frame and the equipment base. The feeding forming assembly includes a plurality of feeding rollers, all of which are rotatably connected within the feeding frame. Two pairs of conveying rollers are disposed within the feeding frame, one end of each pair of conveying rollers being provided with a transmission gear, and one of the conveying rollers being electrically driven to rotate. A main frame is disposed on the surface of the equipment base. This technical solution solves the technical problem in the prior art where sequential feeding leads to an increased idle time ratio in the device, a limited supply of blanks per unit time, and difficulty in matching the high-speed processing capability of the cold heading forming main unit, thus restricting the overall production line's capacity improvement.
