Feeding and discharging mechanical arm for pipe forming machine

Abstract

The invention relates to a feeding and discharging mechanical arm for a pipe forming machine. The font of a moving trolley is connected with a rotary table through a rotary gear; a parallelogram mechanism consisting of a connecting arm, a guide cylinder, an upper connecting rod and a lower connecting rod is formed on the rotary table, and is driven by an elevating hydraulic cylinder and a nose-down pitching hydraulic cylinder; the guide cylinder is provided with a gear driven by a telescopic motor, and the gear is meshed with a rack on the outer side face of a cantilever; an overturning arm and a clamp extend out of the front end of the cantilever; and each hydraulic cylinder is driven by a hydraulic control system. By simulating steps of a manual feeding and discharging method, the feeding and discharging mechanical arm can flexibly complete seven actions, namely clamping materials, stretching a nippling lever, horizontally lifting the nippling lever, pitching the nippling lever, overturning the nippling lever, rotating a frame in a 360-degree range, and walking the trolley, greatly lightens labor intensity of workers, improves work efficiency, and is safe, flexible and easy to operate.

Description

technical field [0001] The invention relates to the field of pipe fitting processing equipment, in particular to a loading and unloading manipulator of a pipe fitting forming machine. Background technique [0002] Large-diameter seamless tee pipe fittings are usually formed by hydraulic extrusion with a cold forming machine. At present, manual loading and unloading is mainly used. This kind of pipe blank is bulky and heavy, and at least two people are required to carry it and put the pipe blank into the press. The extrusion die of the machine is taken out from the die after the extrusion is completed, and the residual hydraulic oil inside the pipe needs to be poured out. Not only the workload is large, the production efficiency is low, the working environment is poor, and the operation under the press is prone to accidents. security incident.
