Driving device of auxiliary trip holder of fully-automatic pipe bender

Abstract

The invention discloses a driving device of an auxiliary trip holder of a fully-automatic pipe bender. The driving device comprises the auxiliary trip holder, wherein the auxiliary trip holder is fixedly arranged on a sliding block; the sliding block is mutually matched with a sliding rail arranged on a head section; the central part of the front end of the auxiliary trip holder is fixedly connected with the rear end of an oil cylinder mutually; a lower end of an installation seat is fixedly arranged on the head section; a thread is formed at the front end of a piston rod; the front end of the piston rod is arranged in a threaded hole which is formed on the installation seat and mutually matched with the piston rod; and a locking nut is arranged at the front end of the piston rod. The fully-automatic pipe bender provided with the driving device of the auxiliary trip holder has the advantages that: the auxiliary trip holder is stressed uniformly during the process of holding elbows, and a guide die is pushed better, so that the guide die can be preferably matched with a wheel die to closely clamp workpieces, and the phenomenon of looseness between the upper end of the guide die andthe upper end of the wheel die is avoided.

Description

technical field [0001] The invention relates to a fully automatic pipe bending machine, in particular to a driving device for an auxiliary clamping mold base in the fully automatic pipe bending machine. Background technique [0002] The existing driving device of the sub-clamping die base in the automatic pipe bending machine includes: the sub-clamping die base, the sub-clamping die base is fixedly arranged on the slider, and the slider and the slide rail arranged on the machine head interact with each other. Cooperate, the slider is connected with the piston rod of the oil cylinder set on the fuselage through the connecting plate, the lower front end of the auxiliary clamping mold base is fixedly connected with the rear end of the adjustment rod, and the front end of the adjustment rod is provided with threads, and the adjustment The front end of the rod is arranged in a threaded hole cooperating with it on the adjusting seat, and a locking nut is arranged on the front end ...

AI Technical Summary

Problems solved by technology

In the process of clamping the bent pipe, the piston rod of the oil cylinder set on the fuselage stretches out, and the piston rod pushes the slider to move forward on the slide rail through the connecting plate, and the slider drives the sub-clamp set on it. The clamping mold base and the guide mold base move forward together, so that the guide mold and the wheel mold cooperate with each other. When the slider pushes the auxiliary clamping mold base to move forward, its force point is at the bottom of the auxiliary clamping mold base, and it will The force on the secondary clamping mold base is uneven, resulting in the phenomenon that the clamping is not tight between the upper end of the guide mold and the upper end of the wheel mold
