Description

(54) DEVICE FOR BILATERAL CLEANING

and STRENGTHEN TREATMENT of SHEET PARTS

one

The invention relates to the processing of metals, in particular to devices for rolling parts of rotating bodies of sheet material, as well as devices for finishing and strengthening processing of metals, shafts and end surfaces.

A device for two-sided finishing and hardening of the ends of parts is known, in the case of which there are two knurled heads, the misalignment of the clips, and separators with a deforming element.

P.

The disadvantage of such devices is their limitations and non-universality when used for seaming shells.

The purpose of the invention is the expansion of technological capabilities in bilateral processing.

The goal is achieved by the fact that the device is equipped with a toothed shaft located in the housing with the possibility of contact with the teeth that are made on the yoke and a discharge device placed in the housing and connected with the yoke, while one of the yoke is fixed stationary in the axial direction. /

In addition, the separator sockets are spherical.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A 5 in FIG. one.

The device is a body 1, mounted in a cutter machine holder, to the sides of which the cheeks 2 are fixed, in which two cantilever sliding heads are mounted. The obtour head consists of a separator 3, on the cantilever part of which a toothed ring holder 4 is installed with subheads 5 and b, and deforming elements 7, balls, are installed in the spherical sockets of the separator. The cage and bearings mounted on the cantilever part of the separator are locked

fixed by screw 9, which is inserted into the groove. The left obrat has no axial movement. The right, connected to the piston 10 of the pneumatic cylinder with the nut 11, has axial movement along the sleeve 12, on the shoulder of which the pneumatic cylinder 13 is mounted, which is fastened with screws 14 together with the cover 15 to

16. In the lugs of the cheeks 2, a locking gear shaft 18 with a pulley 19 is mounted on the bearings 17, held against axial movement by the washer 20 and the screw 21. To unload the flexor moment of the separator 3, which is simultaneously the piston rod of the pneumatic cylinder, in the cheek 2 is installed the unloading device, soup from the threaded sleeve 22, three balls 23, screw 24.

The device works in the following way.

The device is installed by the housing 1 in place of the cutter holder of a lathe or a special machine. A plate or sheet with a flat blank 25 is clamped between the end of the mandrel 26 installed in the turning chuck 27 and the end face of the washer 28 mounted on the center core 29. The blank 25 is simultaneously clamped between the deforming elements / balls 7 and the rolling heads, one of which is movable in the axial direction. The axially movable head is connected to the piston 10 of the pneumatic cylinder, which creates a running-in force. The yoke 4 is additionally supported by three support balls with a screw 24. After this, the machine spindle turning on the workpiece 25 is turned on, and the feed is longitudinal when shells are rolled or transverse when the plates are rolled. At the end of the seaming process, inner 24 is weakened and the lateral head is removed from the rolled up part. At the time of the working process, the device in the sockets of stationary separators with different angular velocities rotates the deforming elements — balls 7, which cause the interlocked toothed collars 4 to rotate. wall thickness. This eliminates the possibility of breaking this part of the sheet blank 25, which can break off without an additional drive due to the fact that the cross section does not hold that torque, is applied to the normal rolling process. In addition, the toothed locking shaft 18 partially unloads cantilever work rolling heads from the bending moment. L When using the device for rolling shafts, the deforming elements 7 approach each other to contact, --.the spindle rotation and other Single machine feed.

When finishing hardening of thin-walled plates with a lever for switching the number of revolutions, the spindle

 the lathe is set to the neutral position (while it is easily rotated by hand), then the blank-plate 25 is installed and clamped in this way, then the forced

S drive of the device through the pulley 19, in this case the deforming elements cause the plate 25 to be turned, which is to be run-in, after that the machine transversely turns on, and

0 Finishing and hardening process “plate” 25.

This device allows you to roll the shafts at once with two or four deformed elements, and the productivity and quality of processing is improved.
