SU580923A1 - Tool for profiling cylindrical articles - Google Patents

Description

7 with locking screws 8, and from ne. moving in tangential direction with pin 9.

A 1O channel is provided in the tool to force the supply of liquid smahex to the center of folding and loading.

The working surface of the walls of the holes in the plates has the shape of circles for, given radii. The centers of these circles are displaced one relative to the other so that the point 11 of each circle (fig. 2) lies on the edge 12, which is perpendicular to the caliber of a sucking gauge: section 2.

(When: t е p.jTo produce a blank of a profile with a radius of 2.2 mm from high strength (se 2OO kgf / mm on a 40KXNM alloyed width of 4 mm and a thickness of 0, about 5 mm, the tool consisting of 30 plates 1.5 mm thick, of steel U10A, hardened to a hardness of 62 ".64 HRC, the working surfaces of which are made along a radius of 1.5-2.5 mm. The working surface of an inn" "ment formed by the holes of the plates has input, calibrating and output, retaining: from sharply sprouting the product, sections. the radius of the calibrating area, the axis) 1symmetry of the outer surface of the profiled tape. The radii of the plate openings of the input and output sections of the tool were distributed in such a way that the curving edge of the edge along the gyobesic line on the cylindrical surface of the shaped workpiece was varied from 22 mm to 1 mm. Calibration area had a hole with a radius of 1 mm

Tool output section

The molds smoothly straightened the workpiece without the occurrence of residual longitudinal deformations in the edges and had radii of plate openings from 1 to 2.2 mm.

The workpiece was projected through the tool with a power device.

Using the tool of the described design, profiles of 40KKhNM alloyed tape without waviness of the edges were obtained, with a longitudinal deflection up to 1O-15mm at a length of 0.5 m, whereas using the known tool the continuous deflection at the same length was t60-.18O mm

Form a from b regeni

A tool for profiling cylindrical articles with inlet, caliper and outlet sections, consisting of a set of plates with holes, the working surfaces of which have the shape of circles with specified radii, which are designed to improve the quality of products, centers, working surfaces of the walls of the holes in the plates are displaced relative to the other so that one point of each circle lies on the straight line, perpendicular to the radius of the circle of the calibrating area.
