Internal high-pressure forming production line for pipes in intelligent factory

Abstract

The invention discloses an internal high-pressure forming production line for pipes in an intelligent factory. The internal high-pressure forming production line for the pipes in the intelligent factory accords with assumption of intelligent factories in 'industry 4.0'. All processes of the whole production line can be deployed by a numerical production control system, and all signals are controlled through sensors; different alarm messages can be emitted for failures of any single machine in the production line, and workers can perform repair and adjustment in the first time; besides, an automatic detection mechanism is arranged on a feeding mechanism to detect whether the shapes and the lengths of the pipes accord with forming molds, detection results can be transmitted to internal high-pressure forming equipment automatically, initial positions of machining of the pipes of different lengths are set automatically, and accordingly the work efficiency is greatly improved; finally, at least two molds are arranged on an internal high-pressure forming machine so that multiple pipes can be machined at the same time, the work efficiency is improved, and the total production time can be shortened exponentially during the production of large-batch pipes.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a high-efficiency and fully automatic pipe fitting internal high-pressure forming production line. Background technique [0002] The internal high pressure forming production line of pipe fittings generally includes the following processes: preforming, feeding, internal high pressure forming, mold opening and blanking, cutting, marking and cleaning. Correspondingly, an internal high pressure forming production line requires at least preforming equipment, upper Material racks, hydroforming machines, cutting machines, marking machines and cleaning stations. [0003] The existing production line of internal high-pressure pipe fittings has the following disadvantages: [0004] 1. The internal high-pressure forming machine in the production line can only perform internal high-pressure forming of one pipe fitting at a time, and the work efficiency is low. Especially in...

AI Technical Summary

Problems solved by technology

[0004] 1. The internal high-pressure forming machine in the production line can only perform internal high-pressure forming of one pipe fitting at a time, and the work efficiency is low. Especially in the production of large-scale pipe fittings, it will take a long time, and multiple mold clamping, The parting process will increase the loss of internal high-pressure molds and equipment and shorten their service life;

[0005] 2. The control systems of each equipment in the production line are independent. There is no assembly system to control them as a whole. The signals between various equipment are easy to be confused. When a certain equipment fails, it is difficult for the operator to immediately Know the specific faulty equipment and carry out maintenance;

[0006] 3. Since the shape of each pipe fitting cannot be guaranteed to be exactly the same, before the internal high pressure forming, the operator needs to inspect the pipe shape and length of the pipe fitting to be processed to judge whether it conforms to the forming mold, and then Then adjust the initial processing position according to the detection results. This manual detection method requires visual inspection in many cases. On the one hand, the error is large, on the other hand, it also reduces work efficiency and increases the labor intensity of workers.
