Abstract

The invention relates to the processing of materials by cutting, in particular to the processing of metals. The aim of the invention is to improve processing performance by increasing the number of cutting edges. Cutting elements 2 with cutting edges on the ends, arranged in parallel rows, are fixed to the sleeve by welding. Between the cutting elements there are spacers in the form of corrugated rings 3. In the axial direction, the cutting elements are pressed by the nut 4 and the washer 5. Additional cutting edges are made on the working surfaces of the cutting elements. The cutting elements are made either in the form of concentric sleeves mounted on the rod or in the form of a set of plates with a thickness decreasing from the front surface of the cutting element to its rear surface, and in adjacent rows the thickness of the plates decreases from one end to another. When the tool rotates, the cutting elements work as a cutter tooth, while the allowance is cut due to the bending of the cutting element. 2 hp f-ly, 10 ill.

The invention relates to the processing of materials by cutting, in particular to the processing of metals.

The purpose of the invention is to increase the productivity of processing by means of increasing the number of cutting edges.

FIG. 1 but tool shown, general appearance; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - incisal element, incision; in fig. 6 - tool, general view, option; in fig. 7 is a cross-section of the FIG. 6; FIG. 8 is a section DD-D in FIG. 6; in fig. 9 is a section of the EE of FIG. 6; in fig. 10 - incisal element, cut.

The surface treatment tool includes a sleeve 1 with elastic cutting elements 2 mounted on it in parallel rows, and gaskets in the form of rings 3 located between the cutting elements 2. The number of corrugations on each ring 3 is equal to the number of cutting elements 2 in the row. The cutter elements 2 are fastened on the ring gasket when pressed by the nut 4 through the washer 5 and on the inner end by welding. The cutting elements 2 are made in the form of concentric tubes 6 (Figs. 1-5) interconnected and mounted on the rod 7. On the tubes 6 and the rod 7, along their outer surface, additional annular cutting edges 8 are formed by grooves with undercuts.

The assembly and operation of the proposed tool is carried out as follows.

Tubes 6 and rods 7 of the same length are cut, while one rod 7 and several tubes 6 are included in the set of one cutting element 2, the inner diameter of which is equal to the outer diameter of the rod 7 and the previous pipe 6. The number of tubes 6 supplied maybe one to four. On the outer surface of the tubes 6 and the rod 7, cutting edges 8 with a depth of not more than 0.5 mm and a width of up to 3 mm are applied by grooves and undercuts. A set of the cutting element 2 is assembled, possibly with a strain, the tubes 6 and the rod 7 are welded along the inner end. On the sleeve 1 by means of welding install the cutting elements 2, which can be installed both radially and tangentially, at an angle of not more than 10-20 °. Parallel rows of incisal elements 2 may be located in planes perpendicular to the axis of the circle, or in a spiral, the angle of inclination of which depends on the diameter of the incisal elements 2, on the diameter of the sleeve 1. The gaskets may be circular or in the form of a spiral Dot cutting elements 2. Place the gasket between the cutting elements 2, install the washer 5, screw the nut 4 and pressing the nut 4 together with the washer 5 to ensure interaction of the surfaces of the cutting elements 2 and rings 3. When you rotate the tool This cutting element 2 works like a cutter tooth, and the treatment is carried out by the force acquired by the cutting element 2 in elastic bending, which allows the cutting tool 2 to cut the seam allowance from the part or material. Each tool element 2 through one turn of the tool comes into contact with the work surface. The rods 7 can be from two to 10 mm thick, and the tubes 6 can also be made from the rod when removing

central part. The thickness of the tubes 6 can be from one to 3 mm. The outer diameter of the cutting elements 2 can be from 4 to 20 mm depending on the removed allowance. The number of cutting elements 2 in the row depends on the diameter of the sleeve 1, while

 the cutting elements 2 on the sleeve 1 is placed close to. The number of rows of cutting elements 2 can be from two to eight, with a larger number of rows complicating the assembly and the interaction of elements 2 with rings 3 deteriorates. The length of cutting elements 2 can be from 40 to 100 mm depending on the seam allowance on the surface being machined and type of material. The installation diameter of the rings 3 depends on their thickness, which can be from 2 to 5 mm and the number of cutting elements 2 in the row.

The cutting elements 2 can also be made in the form of sets of plates 9 (Fig. B-10), on the working surfaces of which additional cutting edges 10 are made. At the same time, the thickness of the plates in bore 5 decreases from the front surface of the cutting element to its rear surface, and in adjacent rows, plate thickness decreases from one tool end to another.

0 Additional cutting edges 10 IMO- can be straight, parallel to the tool axis or can have a diamond-shaped profile. The thickness of the plates 9 can be from 1 to 8 mm, and the thickness of the set of plates 9 can be from 3 to 20 mm. Width

5 plate 9 can be from 5 to 30 mm. The number of sets of plates 9 (cutting elements 2) in a row depends on the diameter of the sleeve, while the cutting elements 2 on the sleeve are positioned closely. The number of rows of cutting elements 2 can be from two to eight. The length of the cutting elements 2 can be from 40 to 100 mm, depending on the seam allowance on the treated surface and the type of material.
