Description

one

The invention relates to cold working of metals and alloys by the method of cutting and simultaneous dynamic surface plastic deformation. It can be used for finishing linear surfaces.

Known tools, in the annular groove of which are located deforming elements circulating under the action of compressed air.

Known combined tools, in the case of which the cutting elements and the knurled head are fixed with deforming elements located in the annular groove and perceiving the impact of the working agent supplied through the axial channel and the holes made in the knurled head 1, 2.

In this case, the deformation is made to cover a small width of the surface to be machined; therefore, the tool has a low productivity, especially when machining flat surfaces of a significant width.

The aim of the invention is to improve the quality of the treated surface.

For this, the tool is provided with a diaphragm mounted rotatably over the annular chamber, in which inclined channels are made, wherein a cavity is formed between the diaphragm and the body.

Cutting elements 2 are installed in the tool body 1, and a knurled head 3 is located inside, in an annular chamber 4

10 of which are deforming shchary 5, kept from being pulled out by the separator 6. Bearing 7 with diaphragm 8 is installed in the upper part of the rolling head. Inside the case is a working chamber 9,

15 communicates through the axial channel 10 and the pipe 11 with a compressed air source. In the diaphragm and knurled head, a system of channels 12, 13, 14 is made, through which the compressed air enters the deforming elements.

The processing with the combination tool is carried out as follows.

The tool is fixed in the chip of the milling machine and the main movement is communicated to it, and the parts are driven to move. When the Schindel is turned on, the cutting and deforming elements begin to rotate, moving in a circular path, while the diaphragm remains stationary.

30 When the detail of the feed motion is communicated, cutting elements first enter the surface, removing the surface of the chip removal, and then deforming the balls. Simultaneously with the inclusion of a double-feed in the working chamber, compressed air is supplied, which, through the channels 15 of the diaphragm, causes it to rotate. Prk it vran1, enpn dnafragma alternately then opens and closes ensemy channels. When channels 12, 13 are open, compressed air is supplied to deformed elements, causing them to remain above the treated surface, with further dual diaphragms of the rotor system; channel systems 13 are closed; channels 14 are opened and pass through the deforming elements, which open to the deforming elements, .nm kinetnic energy. When the ball is machined and the surface is struck, it repeatedly strikes 1-st 1s, as a result of which the elastic deformation of the surface part is absorbed. By changing the angular location of the air duct of the canal; 1n their size, speed of rotation, feed of the part and the number of deformed points, you can adjust the microrelief of the surface and the surface. The required impact energy is determined by changing the magnitude of the air pressure, the geometric parameters of the channels and the diameter of the balls. The exit chamber of the annular chamber and the channel 16 is compressed (the th AIR removes metal chips and dust formed during the processing of the cuttings of the elements, eliminating the possibility of its destruction and the formation of the spheres. A combination tool for treating n-surface and surface grids, comprising a housing in which a cutting edge, a cutting head, and a knurled head with deforming elements located in a collar kaiavka and military equipment, working through an axial canal: an opening, an opening, and an impact agent, which is applied through an axial canal: hole, a hole, a hole, and an impact agent, which is applied through an axial canal: hole, a hole, a hole, and an impact agent, which is applied through an axial canal: an opening, a hole, a hole, and an impact agent, which is applied through an axial canal; e in the knurled head, about the l and h and; and with the fact that, with the improvement of the quality of the surface being treated, the tool is equipped with a diaphragm installed above the annular groove with the possibility of rotation and in which Iolite is formed between the diaphragm and corus.
