Description

one

The invention relates to the field of engineering.

Devices are known for switching the feed of a cutting caliper on pipe cutting machines, made in the form of re-adjustable stops fixed to the machine support and acting in the process of movement to limit switches.

However, in these devices, readjustment of the position of the stops is required when changing the diameters and wall thicknesses of the pipes being machined, which reduces the productivity of the machine. Additional loss of working time in these machines is also due to indirect control of the beginning and end of the working feed.

In order to increase accuracy and reduce the auxiliary time when processing workpieces of various sizes, the switching element is designed as a double-arm fixed on the slider, one arm of which is installed below the saw forming the pressure roller, and the second arm interacts with the proximity sensor.

The drawing shows the proposed device, the operating position.

The device has two drive rollers 1, on which tube 1 is laid, a roller 3, a drive 3, a feed drive 4, a support 5, a bearing tool holder 6 with a cutting cutter 7, a two-arm lever 8 mounted on the axis P connected through a bracket with a slide (not shown). On the upper arm of the lever 8, a shunt W is inserted into the slot of the proximity sensor //. The device works as follows. The lower arm of the lever 8 is in the initial position a few millimeters below the forming of the pressure roller, and the non-contact

the sensor is shunted. The tubes in the machine are driven by rollers 1 rotating in one direction. The pipe is laid on the drive rollers / and the pressure roller 2 pressed in the slider (not shown in the drawing) is pressed against them. Together with it, the caliper 5 moves with the tool holder 6 and the cutting cutter 7. Simultaneously, the double-arm lever 8 mounted on it moves down. As soon as the lower arm of the lever 8 touches the pipe, the lever rests on the end of the pipe to be cut, the latter will rotate around the axis 9 , and the shunt W comes out of the slot of the sensor //, deshuntiru it. By this time, the pinch roller is on the tube, and

the latter will begin to rotate. The lowered sensor 11 gives a command to supply fluid to the actuator 4 of the working feed of the caliper 5 and the cutter 7 will begin to cut the pipe. Since the lower arm of the lever 9 rests on the end

pipes going to cut, as soon as the cut is separated from the pipe, the lever is driven by its own weight; it rotates around axis 9 and shunt 10 bridges the sensor, which gives a command to raise the slide and caliper 5 to its original position. - The cut pipe is removed and the next feed is removed, work resumes in the sequence described.
