The invention relates to the field of engineering and is intended for mechanization and automation of Assembly operations when sealing high pressure hoses non-collapsible design.

It is known device [1] for compression couplings, containing situated in the housing support matrix with a tapered internal the pores, crimp jaws with conical outer surface, and drives the reciprocating movement of the support are: for primary compression couplings - rotating matrix for the final compression - hand pump.

The disadvantage of this design is the low productivity, because the operation is performed in 2 stages. Additionally, this installation cannot compress the coupling welded to the tip of the pipe and flange.

It is known device [2] for compression couplings with two polumbaum with radial Cams in them, acting on the clutch and the drive movement of Cams. The drive movement of Cams made in the form of two volumetric. in which with the possibility of radial movement installed polumbaum, and placed between the working surfaces of volumetric and the ends of the Cams polumbaum spring half-rings. The device allows compressing the pipe with flange and some angular tips. The disadvantage of this device is non-simultaneous convergence of Cams to the surface obitaemoj clutch.

First of all converging Cams located in the area of the connector, last Cams located in the area of the plane simtelnet crimping the outer surface of the coupling will have an uneven drop relatively objetos surface.

In addition, the spring semi-circle is in constant friction with the inner surface of polimetrica. For operation of this device will require expensive hydraulic press. The purpose of the invention to improve the quality and reliability of the process of compression.

This objective is achieved in that the device for compression couplings with two polumbaum with radial Cams which drive the Cams move, including moving from the actuator towards each other floaters, which have polumbaum with Cams, each of the sliders provided with plungers, interacting with Cams. Each plunger, located on the axis of the device, interacts directly with the Cam, and the other plungers from swinging on the floaters, the axes of the rollers, kinematically connected with Cams arranged at an angle to the axis of the device. Axis all Cams in the initial pre-compression position, and when the compression intersect in one point.

The proposed device provides a uniform swage couplings with sleeve, with soldered pipe or flange.

In Fig. 1 shows the device in the initial position; Fig. 2 - the same, at the end of robocast includes a housing 1 (Fig. 1) installed in slots 2 sliders (Fig. 1) and the drive movement of the slide 2 in the form of a floating hydro or pneumatic cylinder 3 (Fig. 1), the force from which the slide 2 is transmitted through the levers 4 (Fig. 1) mounted on the axis 5 (Fig. 1), and emphasises 6 (Fig. 1).

In the holes of the slider 2 mounted plungers 7 (Fig. 1) the rollers 8 (Fig. 1, 3), swinging on the axis 9 (Fig. 1, 3), and in the boring slide 2 installed polumbaum 10 (Fig. 1), with radial Cams in them 11 (Fig. 1, 4). Lugs 6 which are installed in the holes of the sliders 2, through the plungers 7, rolls 8, provide synchronous movement Cam 11 mounted in the holder 10.

Spring 12 (Fig. 1) installed between the stop 6 and the slider 2 are a total of greater force than the spring 13 (Fig. 1) installed between the sliders. The tabs 14 (Fig. 1) limit the slide 2 in the extreme positions. Springs 15 (Fig. 4) pushing the Cams 11 and plunger 7 through rollers 8 move the sliders 2 to its original position.

Spring 13 (Fig. 1) return the slide 2 at the initial position. Spring 12 pushing lugs 6 relative to the slider 2 to the limit of screws 16 (Fig. 1). The screws 17 (Fig. 1) serve to limit the stroke of the plungers 7. Between the stop 6 and the slider 2 is set alinuenue support 20 (Fig. 3) with the bolt 21 (Fig. 3). The movement of Cams arranged at an angle to the Central axis of the device, is carried out when exposed to the rollers 8 on the plungers 22 (Fig. 1, 2).

The device operates as follows.

In the initial position of the lever 4 by means of a power node 3 apart, floaters, 2 under the action of the spring 13 is moved to the extreme clamps 14, the lugs 6 under the action of the spring 12 is shifted to its original position.

The Cams 11 polumbaum 10, the rollers 8, the plunger 7 under the action of the spring 15 is extended to the original position.

In this position between the slide 2 in the resulting gap on removable adjustable legs 20 are placed on the high-pressure hose with attached sleeve and tip 19. With the inclusion of the power node 3 levers 4 approach each other and begin to move the lugs 6, which first through springs 12 bring floaters, 2 to medium clamps 14. In this position, the clearance between the slide 2 is absent, and the Cams 11 occupies a radial position relative to the axis of the clamp coupling 19, the axis of the Cam intersect in one point.

Upon further movement of the lugs 6, floaters stopped moving under the action of the levers 4, the spring 12 is compressed, and simultaneously move the plungers 7 and are 6 move synchronously Cams, located on the Central axis. Cams synchronously moving, compresses the clutch 19. The crimping depth is regulated by the adjustment of the thickness of the washers 18 (Fig. 2).

Device for compression couplings containing slides, mounted with the possibility of a counter-movement from the actuator, which has two polumbaum with radial Cams in them, wherein each of the sliders provided with plungers, driving of said actuator, a part of which, having the same direction of movement with Cams made with the possibility of direct interactions with them, and the other part of plungers, a moving direction which does not coincide with the direction of movement of the Cam - engagement with the Cams by swinging on the axis of the rollers.

2. The device under item 1, characterized in that the axes of all of the Cams when the compression intersect at one point.
