The invention relates to the field of repair of railway rolling stock, in particular to the restoration of the buildings of the coupler with pognutyj shanks. The inventive heating and editing are carried out together in one device to heat pognuti area of the shank of the coupler body to a temperature not lower than 800oWith and the application of a bending force to the end portion of the shank when it is samosogrevanie. A device for implementing the inventive method provides for the accommodation of the shank in a rectangular box, the upper part of the body, the side faces of which have slopes that provide a snug fit to the side edges of the shank when it is resting in the process of editing console pinched the head of the coupler, and in the lower part of the body is fixed in mutually perpendicular directions, two hydraulic cylinders with opposite them restrictive stops working surfaces which are in the same planes as the corresponding faces of the rectangular window. Increased productivity, reduced energy intensity. 2 C. p. F.-ly, 3 ill.

The invention relates to the field of repair of railway rolling sostavnyh shank (1, 2, 3), providing for heating of the shank of the coupler to a temperature of 800o-850o(In the chamber of the furnace or induction heater) with the subsequent horizontal placing it in the working space of the press and edits pognuti zone scheme 3-point lateral bending to restore the linear position of the longitudinal axis.

The disadvantages of this method are the need to have at least two operating positions (for heating and editing), causing the decrease of the productivity process, increasing energy costs and inefficient use of production space.

The technical challenge is to increase productivity straightening bent shank, reduced energy consumption and reduced need for production facilities.

The task is achieved by combining the operations of heating and edits on the same technological position.

For which the shank of the coupler is placed vertically with its samosogrevanie in the transition zone to the head of the coupler, is carried out in this position the induction heating pognuti zone and create transverse bending console application in the horizontal plane straightening efforts to end the Zoe with existing permits: 1. Significantly reduce the overall time editing shank.

2. To eliminate the separate position of the heating of the shank, by combining the operations of heating and edits in a single device.

3. To eliminate the operation of transportation coupler from the position of the heating on the position of the editing and related transactions lowering installation and removal of the coupler from the position of the heating.

4. To reduce the cost of energy, as the edit operation performed immediately after the shank of the coupler minimum allowable temperature, and heating of the shank to a higher temperature to create supply heat necessary for the temperature of the shank, declining over time transportirovano-installation operations, has not fallen below the permissible, not required.

5. To halve the force applied to the shank to edit.

Widely known device for straightening shank coupler (presses, hydraulic and pneumatic drive), in which the case is made with horizontal placement of the shank. The analogue can be used to "press for redress of the coupler body" described on page 177 of the book centuries Kolomiychenko and other "automatic coupler device jelly is the Impossibility of combining heating and edits in a single device, why it is a specialized position for heating the shank of the coupler.

3. The need to transport and install in horizontal position automatic coupling with the heated shank, during which part of the heat is useless wasted.

4. The need to have transportirovano mounting means for the transportation and installation of the coupler to the press in a horizontal position.

The technical challenge is to increase productivity straightening bent shank, reduced energy consumption and reduced need for production facilities.

The task is achieved by combining the operations of heating and edits in a single device. This is accomplished using a device consisting of a body, in the upper part of which is made horizontal rectangular window with the side edges, second side edges of the shank, designed for vertical placement of the shank of the coupler and its samosokhraneniya in the transition zone to the head of the coupler.

In the Central part of the body is the induction heater to heat pognuti zone of the shank to a temperature not lower than 800oWith the mechanism of its regulation by the situations directions two hydraulic cylinders designed for a console application in the horizontal plane straightening efforts to limit the area of the shank and opposite them are restrictive stops working surfaces which are in the same planes as their corresponding side faces of the rectangular window. The device also has a control system heating and edit, not related to distinctive features.

This embodiment of the device provides a vertical position pognuti zone of the shank within the induction heater.

Directly after reaching pognuti zone shank temperature 800oWith his end zone is applied in one or both horizontal directions console applications, straightening force, providing transverse bending of the heated zone. Edit terminates at the contact of the side faces of the end zone shank with limiting stops opposite the cylinders, installed so that the operating surfaces of the stops were in the same planes as their corresponding side faces of the rectangular window of the device.

The claimed device is schematically depicted in Fig.1. In Fig.2 - is the Rhu village, it, which made a rectangular box with 2 faces, having a slope equal to the slope of the corresponding faces of the shank of the coupler, l-shaped adjustable limiting stops 3, the thrust faces which lie in the same planes with the corresponding side faces of the rectangular window 2, the induction heater 4, attached to a soft suspension to the posts controller its height position 5, the power cylinder 6 with the push head 7 to edit the bending of the shaft in the horizontal plane, the power cylinder 8 with the push head 9 to edit the bending of the shank in a vertical plane.

On the top plate frame mounted buttons control the induction heater 10, the dial 11, showing the temperature of the heated zone, the buttons control the hydraulic pump 12, the valves control the hydraulic cylinders 13, 14, the switch 15 from manual control to automatic, signal lamp 16, 17 of the device in manual or automatic mode.

In manual mode, the device operates as follows.

The couple descends vertically shank in box 2, where closecropped due to the fact that the walls of the Windows are made with a slope equal to the slope of the faces of the shank of the coupler.oC. Then the button 12 includes a hydraulic pump (not shown). Depending on which direction when the working position is bent shank (horizontal or vertical) is driven by a respective hydraulic cylinder. For example, the shank of the coupler has a bend in the horizontal plane. In this case, the valve 13 is actuated cylinder 6, which, acting on the end area of the shank through the push head 7, straightens the bend. The deformation continues until the bent longitudinal axis of the shank reverts to its original position, the end area of the shank will reach adjustable limiting stop 3.

Similarly, you can edit the shank of the coupler, having a bending in the vertical plane.

The use of the proposed device allows you to: 1. To increase productivity by combining in a single device for heating and fixing shank of the coupler.

2. To free up production space previously occupied the position of heating the shank Autost energy by reducing the time from heating the shank until it changes.

5. To halve the force applied to the shank to edit.
