Description

The invention relates to the treatment of metals with BneHHeNf and can be used for finishing and strengthening the processing of spiral grooves in the holes of the blanks, HanpuK-iep thread. A device for plastic deformation of a conical surface is known, comprising a housing with a separator disposed therein carrying deforming elements, the deforming elements being placed in a helical groove. The main disadvantage of the known device is the rapid wear of its defining elements x, due to their continuous contact with the treated surface during operation. The closest in technical essence and cognizable result of the invention is a pulse-impact tool for finishing the bodies of revolution, comprising a body with an axial bore, stakes mounted on the body, rolling bodies placed between the body and rings, and a separator with deforming elements made in the form of a sleeve, covering the rolling element 2. The well-known pulse-percussive tool for ch1GSTOVOY treatment of internal surfaces is intended for the treatment of the surfaces of cystrydated holes This method cannot be used for machining spiral grooves, for example, thread knobs. The aim of the invention is to extend the technological capabilities of the tools by enabling the processing of spiral grooves. According to the invention, the goal is achieved due to the fact that the deforming elements in the separator are located along the BINT line, which has an elevation angle and direction of the inlet angle corresponding to the elevation angle and direction of the spiral groove being machined. According to one of the embodiments of the tool, the separator is installed with a rotatability around its own (x: i. Fig. 1 shows the tool, general view; Fig. A, -A. A. 1. 1 l-lKfnynbCHO-ynapHbJfi HUCTpjivfeHT rivals KOptryc 1 , BbintOTHenny in the form of a body with a central axial hole of rotation, on which, using two rings 2, a svarator 3 is installed, in the form of a sleeve connected to the hinges 4. Rings ycTaViOBneHbi on the outer side of the case along the skid: The gasket 5 and the threaded plug 6 together with separate The bottom of the separator, facing each other the ends of the kopea and the part of the snug surface of the body form a closed skull groove 7, in a section of the ring, are shaped in the shape of the shape of the figure, performed in the shape of the figure, and the shape will be applied in the shape of the shape of the shape of the figure. Chiarias from different spear groups did not mix up and moved in the course of work on a given trajectory of the formed. The surfaces of the housing 1 and the separator 3 are filled with interlaced raz- {split bushes, the number of which in Koprrvce and the separator equal to the number of annular rows of balls 8, the symmetry planes located one above the other on the rad1g / skiat of the grooves in the housing and the separator coincide . In the planes of the sym ™ metrrl rad1-gus grooves in the casing, the axes of the channels are placed; 9, the direction of the tang & lpkshnno to the surface of the axial bore of the casing. In these same planes, the axes of deforming elements 10 are located, precetaging cylinders of a cylinder (one of the torrents of which, in the course of working with the pHKOMHs Di raomjeH is spherical, and the other, which is injected, is in the form of iverkhshtsti rotation, imeedey in axial eechenki refigyg same with the profile of the processed, helix spiral grooves. To protect from falling out of the tool, 10 elements from the tool when removing it from the workpiece on the separator wear safety wire rings I Ij input 5a. the surface of the deforming simplexes. By the method of the deforming elements placed in the separator 3, there were made the parallel holes, the springs P1 for removal from the annular groove 7 of the waste medium under the pipe, the Devices 10 were placed in the helper section and the direction and elevation of which coincides with the direction and angle of elevation of the processed spiral groove. FIGS. 1 and 2 show the 1PH-pulsed impact tool for processing three-way spiral cutting. Therefore, the number of rads is deformed elements placed along the lines are three. Instrument {ent works as follows. A pre-machined hole with spiral grooves is installed in the lathe chuck and the template with its threaded shank on the mandrel in the tailstock of the machine. Before and after the workpiece, the bushings with the same grooves are installed, and the spiral grooves like in the workpiece, and those and other grooves are oriented. The tool occupies an original position before the machining process being processed in the guide sleeve, while the deforming elements are 10 times more in the grooves of the front guide sleeve. Compressed air through the central axial opening of the housing 1 and the nozzle channels 9 enters the collar groove 7j where it sets in motion along a circular trajectory the balls 8, which, as it moves, the periodic ends of the deforming elements rounded over the spheres, impart shock impulses. The tool receives a feed directed along the axis of the hole. When entering the tool into the workpiece, the deforming elements with their surfaces 6'4i-B .fH hit the surfaces in the inner spiral grooves and made plastic deformation. As a result, the surface of the cavities of the workpiece gets high purity and, due to the work-hardening, high hardness. The exhausted compressed air from the annular groove 7 is removed through the radial openings of the separator 3, while the compressed air entering the treatment calf serves as a cooling medium. After machining is finished, the supply of compressed air is turned off and the tool is withdrawn from the workpiece to its original position in the forward guide sleeve. When machining spiral grooves with a low lift, in particular an EHL thread, the workpiece is rotated, and its rotational speed is matched with the value of the axial feed of the tool. As a result, the tool is screwed into the workpiece by machining it.
If in the tool intended for machining spiral grooves with large lifting angles, which exclude self-braking, the separator is made with free rotation, then during its operation the workpiece rotation is not required. Machining is carried out only with axial feeding of the tool, since this causes the separator to self-inject into the workpiece.
