A feeding mechanism for bending and twisting forming device of space pipe fittings

Abstract

The invention discloses a feeding mechanism used for a space fitting crankling forming device, and relates to the field of space metal pipe fitting plastic working. The feeding mechanism is composed of a delivery component, a crankling component, an electric sliding rail and a wheel set assembly; the feeding component is fixedly installed on a sliding block of the electric sliding rail, and moves along with the sliding block; a three-claw clamping disc on the feeding component clamps a pipe blank, and the pipe blank passes through a first hollow shaft on the feeding component and a second hollow shaft on the crankling component and the wheel set assembly in sequence; the wheel set assembly plays the role in guiding, and the feeding function is achieved through static friction or slidable friction. The crankling component is directly fixedly installed on a rack, spacing of the crankling component and a bending die is constant, and the crankling component outputs constant torsion outwards. The feeding mechanism used for the space fitting crankling forming device has good operability and practicability in forming of the feeding process. The feeding component and the crankling component work independently in the working process to exert torsion on the pipe blank so as to promote the change of a bending plane in the bending process.

Description

technical field [0001] The invention belongs to the field of plastic processing of space metal pipe fittings, and in particular relates to a feeding mechanism for a bending and twisting forming device of space pipe fittings. Background technique [0002] The combined flexible bending and torsion forming method of spatial pipe fittings is widely used in the field of plastic processing of pipe fittings. The forming principle is as follows: figure 1 shown. From the perspective of structural features, the combined bending and torsion forming device for space pipe fittings is mainly composed of feeding mechanism, tube blank, guide die, movable die and other components. When processing space pipe fittings, the movable mold rotates around the guide mold at a certain angle to bend the tube blank, and the feeding mechanism moves along the x-axis to realize continuous supply of the tube blank. At the same time, the feeding mechanism rotates along the x-axis to realize the continuous ...

AI Technical Summary

Problems solved by technology

This forming method has two defects: (1) the feeding mechanism has to undertake the two operations of feeding and twisting the tube blank, and the motion control is troublesome; (2) the distance between the feeding mechanism and the guide die will change, causing the feeding mechanism to act on the bending Point, that is, the torque at point O is constantly changing, which is not conducive to the precise forming of space pipe fittings
