Description

The invention relates to the processing of metals by pressure and can be used for the cold rolling of the outer and inner rings of a planetary fine-modular gear mechanism.

The purpose of the invention is to increase the productivity of processing by reducing the auxiliary time for setting up and improving the quality of processing by increasing the accuracy of centering.

The drawing shows the proposed device.

The workpiece 1 (or several blanks) is installed in the die 2, which is fastened with screws 3 to the holder 4. In the latter, a sleeve 5 is installed, rotating on conical podshpnik 6 interconnected by sleeve 7. The clamp 8 holds screws 9 from axial displacement. The outer reference gear 10 with one end, made in the form of a cone, interacts with the conical opening of the sleeve 5, and the other is placed in the cylindrical opening of the housing with the possibility of axial movement. The spring I2 presses the outer reference gear to the sleeve 5. The latch 13 prevents the outer reference gear 10 to rotate and raises it to the upper position when the housing 11 is moved. The rolling rollers 14 are supported when rolling the teeth onto the housing I1 through the support ring 15 and the bearings 16. After rolling the teeth, the rollers 14 removing the vehicle from the workpiece 1 with the assistance housing 1 1: sleeves 17 attached to the housing with screws 18. sleeve 17 with balls 1: 9 and

half rings 20 with screws 21 Half rings 20 and ring 22 capture the rollers 14 when removing them from the workpiece 1. The ring 22 is fastened to the support ring 15 with screws 23. The internal reference gear 24 is mounted on a press fit in a slider 25, which with the help of sleeves 26 moves along the rails 27. The guides 27 provide the axial arrangement of the inner 24 and overhang 10 reference gears. The slider 25 is raised by the housing 1 to the upper position by means of the sleeves 28 and 17. The sleeve 28 is attached to the slider by screws 29.

The device works in the following way.

The roll-on head, fixed by the housing 11 in the machine support (e.g. carousel), is in its extreme upper position. The workpiece 1 is installed in the matrix 2. The machine southeport lowers the knurled head into the working position. In this case, the outer reference gear 10 of the conical part fits into the conical opening of the sleeve 5 and is pressed against it by the spring 12. The slider 25 with the internal reference gear 24 fixed in it lies on the die 2. The rolling rollers 14 are led to the workpiece 1. The sleeve 4 is driven. The support of the machine enters the knurled rollers 14 into the workpiece 1, Nakatanie gearing profile. After completion of the teeth rolling process. the caliper of the machine pulls the rollers 14 out of the annular gap between the workpiece and the outer reference gear 10. The sleeve 4 stops rotating. The slider 25 (with the aid of the sleeves 27 and 28) and the outer reference gear 10 (with the help of the clamp 13) are raised by the machine support to the extreme upper position.
