The invention relates to the instrument and can be used for rolling tubular housings telescopic tubular contacts.

A device for machining the ends of tubular workpieces. The multi-device and allows simultaneous processing of multiple tubular blanks, it includes a housing, two deforming node (for simultaneous processing of workpieces with two ends), detachable liner, performing the role of a clamping device, with holes for obitaemyh tubes [1] Deforming the nodes contain tapered holes that are looming on the ends of the tubes, crumple them.

The disadvantage of this device is that you can't use it on the treated tubes to perform transverse groove at any desired spaced from the ends of the tube.

It is also known a device for closing the ends of thin-walled pipes [2] consisting of a rotating clip through the walls of which prog is evom the direction of the cone, inner wall which serves as a support body carrying the crimping rollers.

This device has the following disadvantages:

there are no items fine adjustment of the magnitude of deformation of the pipe end;

the device is complicated;

the device prevents the deformation of the groove type at any position on obitaemoj pipe.

The closest analogue to the technical nature of the invention is a device for rolling [3] comprising a housing, guides associated with attached to them rolling elements and walczowski elements, evenly spaced around the circumference of the bearing, copier, interacting with the rolling elements.

This device has the following disadvantages:

there are no items accurately set the amount of deformation zavaltsovyvaya object; there are no elements of retention within a deformable body of elastic elements type springs, which is necessary for the rolling chassis telescopic spring contact.

The purpose of the invention to enhance the functionality and ease of device.

This is achieved in that in a device for rolling the outer workpiece around the inner getscriptname them rolling elements and walczowski elements, the copier in contact with the sliders through rolling elements, introduced a mechanism for regulating movement of the guides radially relative to the workpiece mounted on the housing emphasis in the form of a hinged arm with its free end in position resting in the interior of the workpiece on its axis, and the sliders are made shouldered limiting movement of the slide along the guides.

When the contact Assembly in the tubular ferrule, zahlcovany with one hand, place the first pin with a shank, a spring, a second pin with a shank and produce a rolling cage with butt or perform on the housing groove, which prevents the bounce of the spring and pin from the clip. In connection with great precision parts manufacturing contacts (the gap between the inner wall of the casing and the pin may not exceed 0.02-0.03 mm) and small dimensions of the parts of the contact (the outer diameter of the shroud of 0.5 mm, a wall thickness of 0.05 mm) tolerance on the degree of deformation of the clip should not exceed a few hundredths of a millimeter. In addition, the device should provide reconfiguration for different diameters clips and depth of the deformable grooves.

To meet these requirements, the device enter evocomnet signs enables the manufacture of telescopic tubular contacts, as well as improving the accuracy of the deformation rate.

In Fig. 1 shows the device in side view; Fig. 2 is a plan; Fig. 3 stop; Fig. 4 valueby contact.

The device consists of an electric motor 1 (see Fig.1), the supporting Board 2, the housing collet clamp 3, the nut 4, slide 5, slide with the shoulder 6, the bearings 7 (in the formula referred to as rolling element), copier 8, alzouma elements 9, which deform the body of the contact 10 within which is placed the upper pin with a shank 11 and a compressed spring, the two brackets 12, two screws 13.

The emphasis consists of (see Fig.3) rack 14 and bracket 15 (shown in Fig. 2 in the turned form); a copy of the two guides 8 and shank 16. The design of one of the possible ravnovesnost contact consists of a casing 17, the upper pin 18, with the spring 19, the lower pin 20. The cage is rolled groove 21, it is also possible to rolling the lower shoulder on an empty clip.

The device operates as follows.

After determining the contact type collet clamp is removed from the axis of the engine and turn the screw on the side of the big hole collets set the amount of output contact outside collets (in the drawing, the screw not shown). Then stanalone end down. By rotating the collet holder clamp.

In the clip above install the lower pin, the spring, the upper pin. After that, the lever stop 15 is turned so that the pin retracts into the holder by the pressure of the lever on the top of the shank. Then turn on the engine, which begins to rotate the collet by clicking on the shank of the copier 16, it is moved in the direction indicated in Fig.2 by the arrow. Guides copier thrust bearings 7 mounted on the sliders, which in turn bring alzouma elements that form on the holder nakaku. Convergence alzouma elements sliders occurs before until shouldered rested in the corps of guides 5.

The necessary deflection of the shroud is chosen by moving the guides 5 by rotation of the screws 13. After installation guides fix, screwing the screws to the Board of reference. Return floaters, and copier in its original state is performed by the springs.

When the rack 5 is necessary screws 13 to put them symmetrically with respect to the casing, as at asymmetrical installation will have a bending deformable clip particularly small diameters, such as 0.5 mm and wall thickness of 0.05 mm

Device for rolling out and, have floaters attached to them rolling elements and walczowski elements, copier, contact with the sliders through rolling elements, characterized in that it introduced a mechanism for regulating movement of the guides radially relative to the workpiece mounted on the housing emphasis in the form of a hinged arm, its free end in position resting in the interior of the workpiece along its longitudinal axis, and the sliders are made shouldered limiting the movement of the slider along the guide rails.
