Description

Self-adaptive automatic pipe cutting and threading integrated machine
Technical Field
The invention relates to the technical field of threading machines, in particular to a self-adaptive automatic pipe cutting and threading integrated machine.
Background
The threading machine is a device for performing thread machining on a pipe fitting according to actual conditions when the pipe is installed. For the pipe fittings needing to be cut and sheathed, the cutting device and the sheathing device are generally manually replaced on the sheathing machine to respectively complete the two procedures. Still need consider material transmission, initial positioning etc. and the process is loaded down with trivial details, and is consuming time more, and is very inconvenient, leads to machining efficiency to reduce. The existing pipe fitting processing machinery is generally divided into a manual threading machine and an electric threading machine, wherein the manual threading machine is mostly suitable for processing threads of joints of single water heating pipe fittings, and the problems of low efficiency and high labor intensity exist due to the fact that the threads are required to be processed through manpower, so that the processing machinery is difficult to adapt to the requirements of batch processing and production of pipe bars. The electric threading machine is mostly suitable for processing pipe rod pieces in large-scale processing plants, but the electric threading machine is quite complex in structure, large in size and heavy, brings inconvenience to processing of pipe thread in general engineering decoration, and is high in use cost. Particularly, when the pipe fitting is operated in mountainous areas, the length of the pipe fitting needs to be determined according to actual conditions, and large-scale equipment cannot be moved to an operation site conveniently.
The existing small-sized threading machine clamps a pipe fitting by using a clamp, then the pipe fitting rotates, and manual feed is performed to cut or thread the pipe fitting, so that the small-sized threading machine is heavy in weight, inconvenient to move and relatively slow in processing speed.

When three threading die synchronous contact pipe fitting, the resistance increases, the side ring gear with fast-forward gear meshing takes place slight movement, touch switch passes through the signal line and passes the signal to the controller, the controller stops the rotating electrical machines rotation through the control line, electric putter stretches out, flexible traction motor starts, flexible traction motor makes the expansion ring rotatory through the pull wire, the chute is followed the slide bar motion, with the expansion ring rearward movement, and drive the side ring gear rearward movement, make the side tooth of side ring gear and the tooth contactless of fast-forward gear. The electric push rod stretches out the rear short shaft sleeve brake mechanism, the left swing part and the right swing part clamp the short shaft sleeve, the short shaft sleeve is fixed on the rack, and therefore the outer gear ring is fixed on the rack. And then the controller controls the rotating motor to rotate reversely, the cooling pump and the front moving motor to operate through the control line. The front clamping moving mechanism enables the pipe fitting to slowly move backwards; gear revolve advances slowly to make the feed speed slow down through the worm wheel, the worm, moment increases, the moment requirement when satisfying the mantle fiber, coolant liquid cools off the cutting position from the nozzle blowout, three threading simultaneously carries out the mantle fiber to the pipe fitting, after the definite time, the screw thread on the pipe fitting has been processed, the controller stops after controlling rotating electrical machines corotation definite time through the control line, electric putter withdrawal, flexible traction motor stall, the cooling pump stall, preceding mobile electrical machines stall, cutting knife and threading return to the normal position, side ring gear and expansion ring are because of the extension spring normal position that returns. The staff resets and loosens the pipe fitting through centre gripping moving mechanism before the touch-sensitive screen control.
After the work is finished, the worker firstly cuts off the power supply, then takes down the screw die and the cutting knife, finally cleans the cooling liquid in the cooling liquid tank and takes down the filter cloth from the cooling liquid tank to clean the scrap iron on the filter cloth.
