The utility model relates to equipment for mechanical processing by pressure of a profile material, in particular to straightening welded joints of rails in a cold state.

Known devices for straightening the rail in the cold state.

These devices are taken as analogues. See USSR patent for invention No. 897328, publ. Bull. No. 2 dated 01/15/82, application No. 2909497 / 25-27 dated April 10, 80, B21D 3/02 "Automatic control devices for the process of cold straightening rails on a roller straightening machine."

The device consists of a block of sensors for monitoring the rail at the input, a data conversion unit, a mechanical transmission associated with the data conversion unit and the upper rollers for straightening the rail, the lower emphasis rollers.

The disadvantages of these machines are the need to adjust the reference rail to the “zero” plane, the lack of tracking of the rails welding places, a large number of rollers for straightening the rail, and the lack of the ability to straighten the rail in a horizontal plane. These shortcomings do not allow to achieve the technical result of the utility model, which consists in ensuring the reliability of the machine and improving the quality of the welded joint.

The invention is known which describes the editing of long products using the correct machine, see USSR patent for invention No. 1148663, publ. Bull. No. 13 dated 04/07/85, application No. 3489732 / 25-27 dated 09/10/82, B21D 3/12.

The operation of this machine consists in applying compression forces in a direction perpendicular to the longitudinal axis through the upper and lower shaped rollers, and in applying longitudinal compressive forces.

The disadvantages of this machine are the inability to install the machine in the rail welding line, the presence of a large number of rollers for straightening the rail, the shaped profile of the rollers for straightening the rail, the absence of the possibility of skipping the rail with a kleevolt connection, the lack of the ability to straighten the rail in a vertical plane, the lack of automatic control of the rail geometry. These shortcomings do not allow to achieve the technical result of the utility model, which consists in ensuring the speed of work and reducing the overall dimensions of the installation.

Known machine for straightening rails "Mobile hydraulic press for straightening rails", see French patent for the invention No. 2876925, publ. Bull. No. 06/17 of 04/28/06, application No. 0411316 of 10/22/04, B21D 3/00. This machine is taken as the closest analogue to the prototype. The machine contains a movable frame 2 (Fig. 1) with a casing 6 installed on it (Fig. 1). Integrated in the housing: input rollers; lower cylinder straightening rail; lateral rail straightening cylinder; the upper rotary hydraulic cylinder straightening 12 (figure 1) of the rail, rotating 90 degrees during idle 11 (figure 1) of the rail; upper rotary counter-supports 13, 14 (Fig. 1), having the ability to move along the axis of movement of the rail during straightening and turning 90 degrees during idle rail; brackets with bottom and side counter supports 15, 16 installed in them (Fig. 1), which can be moved along the axis of movement of rail 7 (Fig. 1) during editing. A measuring system with a movable carriage 21 (Fig. 1) and measurement sensors 22, 24, 25 (Fig. 1), rigidly connected to the housing. The disadvantages of this machine are:

- the presence of movable and rotary base stops, the presence of the upper rotary hydraulic cylinder complicates the machine, reduces its reliability and increases the overall dimensions;

- when measuring the geometry of the rail, the measuring rail is pressed against the base supports by hydraulic cylinders, and then the measuring device, which must be rigidly tied to the base supports, makes a measurement, which complicates the design of the measuring system and the machine as a whole, as well as increases the operating time of the machine;

- for editing in the area of the welded joint of the rails, the entire machine (the press installed on it and the hydraulic drive station) is moved along the additional rails installed specifically for the machine, which increases the energy consumption and the speed of the machine;

- the lack of the ability to edit rails with kleeboltovoy connection narrows the uniformity of the use of the machine;

- the presence of input rollers rigidly connected to the housing reduces their life; These shortcomings do not allow to achieve the technical result created by the proposed utility model.

The installation consists of a base 1 (Fig. 1) on which a movable housing 2 is mounted, in which vertical roller blocks 3 are installed (Fig. 7), consisting of levers 4 and vertical rollers 5, connected in pairs by springs 6; blocks of the horizontal roller 7 (Fig.2), consisting of levers 8 and horizontal rollers 9, connected in pairs by springs 10; fixed lower base stops 11, side base stops 12 of the rail sole, side base stops 13 of the rail head, vertical base stops 14 (FIG. 3). This achieves a technical result that is not in the prototype, which consists in increasing the speed of the installation and reducing its weight and size parameters. In the above analogues and prototype such technical solutions are absent.

Horizontal and vertical blocks of rollers 3, 7 protrude a distance L (Fig. 8) relative to the base stops 11, 12, 13, 14, to protect the base stops from impacts when the rail enters the dressing zone and from friction when the rail passes inside the installation. This achieves a technical result that is not in the prototype, which consists in increasing the reliability of the installation and improving the quality of the welded joint.

In the movable housing, guides 15 are installed on which the cross-arm 16 is mounted. In the cross-arm 16 the upper hydraulic cylinder of vertical straightening 17 is fixedly mounted (Fig. 4) ;. This achieves a technical result that is not in the prototype, which consists in reducing the overall dimensions of the installation.

In the movable casing, horizontal editing cylinders 18 are installed; bottom hydraulic cylinder vertical straightening 19 (figure 4); measuring device 20, consisting of a movable measuring bracket 21, laser sensors 22, a guide 23, pneumatic cylinders 24 and a base element 25, which can be made in the form of a roller.

The base 1 and the movable housing 2 are connected by means of a hydraulic cylinder for longitudinal displacement 26 and rollers 27. This achieves a technical result that is not in the prototype, which consists in reducing the energy consumption of the installation. Installation works as follows.

The welded rail 28 is fed into the movable housing 2 (Fig. 1) along the blocks of rollers 3, 7. To measure the geometry of the welded joint 32 (Fig. 7) of the rail 28, the imaginary plane II of the movable housing 2 (Fig. 1) is installed in the center of the welded the junction 32 of the rail (Fig.7), using the hydraulic cylinder of the longitudinal movement 26 (Fig.7). The measuring device 20 (Fig. 5) is mounted with the base elements 25 on the monitored surface K of the rail (Fig. 6) using a pneumatic cylinder 24. The movable measuring bracket 21 is moved along the guide 23, measuring the geometry of the rail 28 in the region of the welded joint with laser sensors 22. The measuring device 20 is returned to its initial state by the pneumatic cylinder 24. This achieves the technical result that is not in the prototype, which consists in improving the quality of the welded joint.

The measurements are processed by an analog block (not shown) and converted into a signal transmitted to the hydraulic cylinders.

Hydraulic cylinders 17, 18, 19 correct the welded joint of the rail.

During operation of the upper vertical straightening cylinder 17, its rod 29 abuts against the rail head, and the rail sole abuts against the lower base stops 11. In this case, the force of the springs 6 is overcome by the force developed by the upper vertical straightening cylinder 17 and the vertical rollers 5 are moved down without participating in the process editing the rail.

When the lower hydraulic cylinder vertical straightening 19, its rod 31 abuts against the bottom of the rail, and the head of the rail 28 abuts against the upper base stops 14.

When one of the side hydraulic cylinders of horizontal straightening 18 is operating, its rod 30 abuts against the rail neck. The rail head abuts against the lateral base stops 13 of the rail head, the sole of the rail abuts against the lateral base stops 12 of the rail sole. In this case, the force of the springs 10 is overcome by the force developed by the lateral hydraulic cylinder of the horizontal straightening 18 and the horizontal rollers 9 move in the direction of straightening, without participating in the process of straightening the rail.

A control process of measuring the geometry of the rail in the region of the weld joint 32 is carried out. In the presence of deformations exceeding the tolerance, the rail is re-edited.

Thus, the above information indicates the possibility of using the utility model in the form described in the utility model formula using the known and proposed tools described in the application. Therefore, the claimed utility model complies with the requirement "industrially applicable under applicable law." According to the proposed utility model, the design and technological documentation for the UPSX-01 UHL4 machine has been developed. A prototype is manufactured and tested. The tests gave a positive result.
