AI Technical Summary

Technical Problem

Existing pipe bending machines suffer from low efficiency, poor clamping effect, easy pipe wear, and low automation during processing. They are particularly time-consuming and labor-intensive when processing multiple sets of pipes, and lubrication is insufficient.

Method used

A heavy-duty pipe bending processing device was designed, which uses a combination of static and dynamic clamps to hold the pipe, and achieves efficient pipe bending through a bending die driven by a hydraulic system and a servo motor. The device also features an automatic lubrication system for the pipe, a lifting cylinder and pressure roller for limit guidance, and an automated material handling mechanism to improve ease of operation.

Benefits of technology

It achieves efficient clamping and lubrication, reduces pipe wear, improves automation, simplifies the operation process of multiple sets of pipes, and improves processing efficiency and safety.

Abstract

The present application relates to the technical field of pipe bending machine, and discloses a heavy-load pipe bending processing device, right machine table and left machine table are connected, the front ends of the right machine table and the left machine table are jointly connected with a bottom table, the upper end surface of the bottom table is vertically installed with a fixed roller, the upper end of the fixed roller is installed with a rotating shaft through a damping bearing, the upper end of the rotating shaft is sleeved with a pipe bending shaping die, a plurality of groups of semicircular shaping grooves acting on the pipeline are arranged on the pipe bending shaping die, and the lower end of the rotating shaft is sleeved with a function gear, when the pressing wheel rotates, the rotating part drives the annular outer track to do the circular motion, when the convex surface contacts the arc head in the movement process, the contact force is generated between the two to make the extrusion rod move to the inside of the lubricating oil groove, the extrusion plug is driven to move oppositely, the lubricating oil in the lubricating oil groove is extruded to make it gush out, penetrates through the guide flow from the oil penetration concave hole position, flows into the contact surface of the pipeline and the inner sliding groove, and the automatic lubrication effect is achieved.
