Pipe fitting double-end pipe contracting device

Abstract

The invention relates to the technical field of pipe fitting processing, in particular to a pipe fitting double-end pipe contracting device. The device comprises a rack, a positioning mechanism arranged on the rack, a feeding frame arranged on the rack, a two-way adjusting pipe contracting mechanism arranged on the rack and located at two sides of the positioning mechanism, and a discharging framearranged on the rack, wherein the two-way adjusting pipe contracting mechanism comprises adjusting pipe contracting mechanism bodies which are the same in structure and arranged on the two sides of the positioning mechanism correspondingly, and each adjusting pipe contracting mechanism body comprises a corresponding fixed frame fixedly mounted on the rack in a vertical state, a corresponding rotating disc vertically mounted on the corresponding fixed frame in a mode of being capable of rotating around the axis thereof, and a corresponding rotating disc driving mechanism arranged on the bottomof the rack, wherein a plurality of hydraulic cylinders are mounted on the rotating discs, and the output end of each hydraulic cylinder is provided with a corresponding pipe contracting mold. According to the device, automatic feeding and discharging can be achieved, pipe contracting can be automatically conducted on the two ends according to pipe fittings with different diameters, the processing precision is guaranteed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe fittings processing, in particular to a double-ended pipe shrinking device for pipe fittings. Background technique [0002] In the metal processing industry, the operation of expanding and shrinking the pipe is usually done by a shrinking machine. The shrinking machine can realize the functions of pipe shrinking and pipe flaring. Pipe flaring is a forming process for expanding the diameter of the end of the pipe blank; in the prior art, the pipe shrinking machine generally includes: a frame, a clamping mechanism for clamping the pipe to be processed, and a pipe for the end to be processed. Partially formed shrinking mechanism. When both ends of the pipe fitting need to be processed, the current practice is to process one end first, remove the workpiece after the processing is completed, and then turn around and then process the unprocessed end, which has low work efficiency, and because of the secon...

Problems solved by technology

When both ends of the pipe need to be processed, the current practice is to process one end first, remove the workpiece after processing, and then process the unprocessed end after turning around. The work efficiency is low, and due to the secondary clamping The coaxiality of the apertures at both ends is poor, and the consistency of the tube length after double-head shrinkage is poor. For some products with high precision requirements, it is difficult to meet the precision requirements. Therefore, we propose a double-end shrinking device for pipe fittings to facilitate solve the problems raised above
