AI Technical Summary

Technical Problem

Existing square and rectangular tube bending devices are prone to scratching the coating on the outer surface of the tube during fixing. The fixing operation is cumbersome and inefficient, and the driving strength is insufficient, making it difficult to meet the bending requirements of square and rectangular tubes of different specifications.

Method used

A bending device with a sliding structure is designed, including a sliding component, a locking component, a driving component, and a bending mechanism. It is driven by a servo motor and a DC geared motor to achieve frictionless fixing and efficient bending of the pipe. Torque is increased by using transmission gears and gear rings.

Benefits of technology

It reduces damage to pipe coatings, simplifies fixing operations, improves bending efficiency and driving strength, and adapts to the bending needs of square and rectangular tubes of different specifications.

Abstract

This utility model relates to the field of rectangular tube production technology and discloses a bending device with a sliding structure for rectangular tube production. The device includes a worktable, a base fixedly connected to the bottom of the worktable, a fixing mechanism on the top of the worktable, and a bending mechanism on the front side of the fixing mechanism. The fixing mechanism includes a sliding component, a locking component, a driving component, a transmission component, and an adjusting component. This bending device with a sliding structure for rectangular tube production, through the fixing mechanism, allows the bottom of the tube to slide against the sliding rollers inside the fixing frame and bending frame when the worker places the rectangular tube. This reduces frictional damage between the tube and the fixing frame and bending frame during installation, protecting the integrity of the coating on the outer surface of the tube. Simultaneously, the worker only needs to start the servo motor and rotate the torsion disc to control the clamps inside the fixing frame and bending frame to move forward, allowing the clamps to cooperate with the fixing frame and bending frame to fix the rectangular tube.
