Abstract

The invention relates to mechanical machining of pipes for flanges by the method of running. The goal is to reduce the size and weight of the structure due to the possibility of using the device on any of the metal cutting machines (turning, drilling or boring). The rolling rollers 4, the working irofili of which are arranged perpendicular to each other, are mounted on movable axes x 2 eyelets. Entering into contact with the inner surface of the processed pipe 9, the rollers 4 begin to rotate and roll along the pipe, expanding its edges and, respectively, flanging and cutting with a cutter 5. 1 Il.

The invention relates to the machining of pipes using the rolling-in method and can be used for flanging the edges of pipes for free flanges, mainly on machine tools (turning, drilling or boring).

The purpose of the invention is to reduce the size and weight of the device.

The drawing shows a device for flanging pipe edges, a general view.

The device includes a case 1 made in the form of a plug and running-in rollers 4 mounted on moving axes x 2 eyes 3 of the case, the axes of which are arranged perpendicular to one another, and the surfaces of the rollers are made in the form of two mutually perpendicular faces matching along the radius.

Each movable axis 2 has a thread at one end, and a restrictive collar at the other, and in the middle part a groove in which cutter 5 is installed, fixed to the indicated axis by a nut 6.

Between the running rollers 4 and the cutters 5, a washer 7 is installed, and between 11 rounds 3 there are nuts 8.

The device works as follows.

After the device is installed in the machine chuck (turning, drilling or boring), the rolling rollers 4 are adjusted relative to the inner diameter of the machined edge of the coarse 9 - the nuts 8 are released, the movable axes 2 with the rollers are installed in a predetermined position and fixed with the same 1 aiki 8.

Then, in the caliper (or vice) of the machine, the end of the pipe is fixed, the spindle is turned on, and the support with the pipe (automatically or manually) is fed into the rotational area of the device — the rollers coming into contact with the inner surface of the pipe, begin to rotate and roll along the pipe , producing expansion of its edges and flanging for free flanges. The cutters 5 ensure the removal of irregularities on the edges of the pipes. The end of the flanging operation is the occurrence of chips from under the cutter.

The proposed device is characterized by a reduction in size and weight and, accordingly, a decrease in its metal consumption 5 and cost of manufacture.
