SU1505649A1 - Method of knurling tooth profiles - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used when rolling toothed profiles on cylindrical billets. The purpose of the invention is the expansion of technological capabilities by increasing the range of sizes of workpieces being processed. During the process, the workpiece is placed between the fixed bar and the knurled roller, which has the ability to rotate and translate. The roller is said to move forward at a speed equal to the linear speed of movement of the blanks. In this case, the workpiece moves between the rolling tools, and the required profile is formed on its surface. During rolling, the workpiece is supported by a pusher that moves synchronously with the knurling roller. The equality of the speeds of the roller, the workpiece and the pusher is maintained at any diameter of the workpieces, which makes it possible to increase the range of sizes of the workpieces being processed. 2 Il.

Description

The invention relates to the processing of metals; 1ov pressure and can be used when rolling gear profiles on cylindrical billets.

The aim of the invention is to expand the technological capabilities by increasing the range of sizes of the processed blanks.

FIG. 1 shows a scheme for rolling profiles according to the proposed method; in fig. 2 is part of one of the possible devices for implementing the method, axonometrics.

The cylindrical billet 1 is moved between a stationary rolling tool — fixedly fixed with a flat plate 2 and a possible rolling tool — a roller 3 mounted rotatably in the movable casing 4. During the rolling process, the rotating roller is coupled with the yoke at a speed equal to the linear speed of movement. blanks. The plunger 5 moves synchronously with the roller. The equality of the speed of the roller, the workpiece and the pusher is maintained at any diameter of the workpieces, which allows machining parts that are in a wide range of sizes.

Example. Rolling the desired profile in a separate section of the long blank is carried out as follows. A blank is placed between the fixed sliding mantle and the movable roller. after which the rolling roller is reported ;: rotation due to its interaction with -;,: cooking and linear movement at a speed equal to the linear velocity of the workpiece spacers. fl (1m in a separate part of the workpiece the required pro is formed, 1b, and the pusher, moving synchronously with the roller, ensures fast

support and the necessary position of the workpiece in the horizontal plane.

The proposed method allows to expand the range of sizes of the workpieces and provides rolling profiles with the help of a knurling tool of simple design.
