Description

Electromechanical integrated threading machine for building construction

Technical Field

The invention relates to the technical field of building construction, in particular to a mechatronic threading machine for building construction.

Background

The threading machine is named as electric threading, which makes the pipe thread processing become easy and fast when the pipeline is installed, reduces the labor intensity of pipeline installation workers, when the threading machine works, firstly, the pipe to be processed with the thread is put into a pipe chuck, is impacted and clamped, presses down a starting switch, the pipe rotates along with the chuck, adjusts the opening size of a threading die on a threading die head, sets the length of a threading opening, then, a tool feeding hand wheel is pulled clockwise, so that a threading die cutter on the threading die head is attached to the end part of the rotating pipe with constant force, the threading die cutter automatically cuts threading, meanwhile, a cooling system automatically sprays oil for the threading die cutter, when the threading opening is processed to the preset length, the threading die cutter automatically opens, and the threading opening processing is finished; meanwhile, the threading machine also has a pipe cutting function, a cutting knife rest on the feeding device is put down, a feeding hand wheel is pulled, a blade on the cutting knife rest is moved to a length point which is required to be cut off, a handle on the cutting knife is gradually rotated, the blade extrudes the rotating pipe, the pipe is extruded and cut off by the blade after rotating for 4 circles and 5 circles, but the pipe has some defects in the use process, as follows:

firstly, the steel pipe is threaded, only the left side is fixed by the three-jaw chuck, the left end of the steel pipe is in contact with the screw die cutter, the distance between the three-jaw chuck and the screw die cutter is long, when a motor drives the steel pipe to rotate through the three-jaw chuck, firstly, the left end of the steel pipe generates a large axial force, the steel pipe and the three-jaw chuck can easily slide relatively, and huge abrasion is generated, meanwhile, when threading possibly exists, the steel pipe is clamped with the screw die cutter, the threading process is interrupted, the threading efficiency is greatly reduced, secondly, when the steel pipe is clamped, no contrast reference object exists, axial deviation is easy to occur, when the steel pipe is in contact with the screw die cutter, severe collision is generated, threading is interrupted, even the screw die cutter is broken, and huge loss is caused.

Secondly, when the mantle fiber machine, need confirm the diameter of steel pipe, and then select the die head of different length, change, simultaneously, every group die head has 2-4 at least, and the change process is very loaded down with trivial details, changes the back, need finely tune the die cutter, perhaps tries the mantle fiber, in case improper operation, then causes the mantle fiber mistake to appear, needs the sawing off steel pipe, carries out the mantle fiber again, causes huge waste.

Thirdly, when cutting off the steel pipe, the steel pipe is extruded by the blade, and in the extrusion process, the steel pipe is pressed, so that the left end of the steel pipe is deformed, the subsequent threading processing quality is influenced, and after the steel pipe is extruded to be broken, burrs are easily left at the left end of the steel pipe, and the fracture quality of the steel pipe is influenced.
