The invention relates to the processing of metals by pressure and can be used simultaneously for thickening on both ends of the workpiece, for example, for subsequent stamping.

A device for electronically containing the landing mechanism with mechanical contact blocks radial contacts and case (I. E. Nathanson, G. M. Telnov. The electric heating method, a resistance and electronicaga. M: mechanical engineering, 1964,page 95...99). In such devices receive bulges on both ends of Zagato for bilateral electronically, containing the left and right mechanisms landing face contacts, landing cylinders, blocks of the upper and lower radial contacts and mechanisms of the clip and the body (I. E. Nathanson, G. M. Telnov. The electric heating method, a resistance and electronicaga. M: mechanical engineering,1964, page 99...102). In such devices it is possible to simultaneously obtain bulges on both ends of the workpiece.

The disadvantage of this device is the design complexity associated with the existence of a power cylinder blocks lower radial contacts. The disadvantage is the complexity of the service associated with the difficulty of accessing the elements of height-adjustment of the lower radial contacts inside filled transformers and singatoka of the device, as well as with an increased height of a loading and unloading zone of the device, resulting from the necessity of placing these power cylinders above the transformers.

The disadvantage of this device are also limited technological capabilities associated with the difficulties of readjusting to electrolysed workpieces of different diameters and lengths.

The aim of the invention is to simplify the design by eliminating the silo is maintenance due to ease of access to the elements of height-adjustment of the radial contacts, and by reducing the height of a loading and unloading zone of the device.

The aim of the invention is the expansion of technological capabilities by manufacturing electronically different sizes of blanks.

This goal is achieved by the fact that the device for bilateral landing, containing the left and right mechanisms landing face contacts, landing cylinders and blocks of the upper and lower radial contact, the clamping mechanisms and the housing, each of the mechanisms landing contains 2 poluchaeti made with the possibility of movement on the General guide, one end of which is connected with the contact and landing cylinder and the other with blocks of the upper and lower radial contacts and supply drive individual travel, and the block lower radial contact is made in the form of a rod associated with the radial contact with the host helical gears.

This goal is achieved by the fact that the left and right landing mechanisms installed on individual platforms, configured to move relative to the body.

In Fig. 1 shows the device in the initial position; Fig. 2 - the same process you is SS="ptx2">

The device (Fig. 1, 2, 3, 4) contains the left 1 and right 2 mechanisms landing. Each of the mechanisms landing 1 and 2 contains landing cylinder 3, for example, a pneumatic, a rod which is connected with polyuretha 4, on which the fixed end of the contact 5. Each of the mechanisms landing 1 and 2 contains Polyanichko 6, on which the blocks 7 of the upper radial contact 8 and the blocks 9 of the lower radial contact 10. The block 7 is made in the form of power, for example, the pneumatic cylinder 11 (Fig. 5) that is attached to polyanede 6 bracket 12 on the rod which is fixed radial pin 8. The block 9 is made in the form of a rod 13 that is associated with a radial pin 10 and the node 14 helical gears, comprising performed on the rod 13 thread 15 and the key groove 16, mounted on polyanede 6 stops 17 and pins 18 and installed in the limiter 17 coaxially them nuts 19. The stoppers 17 are in the form of half rings and cover the nut 19 in part. Polucaetsa 6 is equipped with a drive 20 individual movements made, for example, in the form of a pneumatic cylinder 21. Poluchaeti 4 and 6 are installed on the common rails 22. The guides 22 are mounted in the bearings 23. The device is provided with a clamping mechanism 24, consisting of power, for example, p is s 1 and 2 landing cylinder 3, support 23, the pneumatic cylinder 21, the bracket 26 and pad 28 mounted on the platform 29. Platform 29 fixed to the body 30 of the device and have the ability to move relative to the housing by means of screw 31. Inside the housing 30 has two number of mechanisms landing of the transformer 32. The transformers are connected by a flexible tire (not shown) with axial and radial contacts. Also shows the workpiece 33 and article 34 after the landing.

Before you begin rotation extend beyond the limiter 17 and nuts 19 moves vertically, the rod 13 with the lower radial contacts 10 and get to the workpiece 33, based on the lower radial contact 10 and the bed 27, was aligned to face contacts 5. Thus the vertical movement of the rod 13 is provided with dowels 18, precluding rotational movement of the rod 13. Before you begin rotation driving of screws 31 to move the platform 29, achieving the required distance between the end pins 5, corresponding to the length of the workpiece 33.

The operation of the device is as follows. The blank 33 is placed on the lower radial contact 10 and the bed 27. Next is the workpiece clamping cylinders 25 and the m billet 33 between the end pins 5, which is accompanied by movement of polyuretan 4 and 6. While the workpiece is held from longitudinal movement in the clamping mechanisms 24 and slips relative to the radial contacts 8 and 10. Next, voltage is applied to areas of the workpiece between the end and the radial contacts, the workpiece is heated at these sites and is bilateral electronicaga, followed by a move polyuretan 4 and 6, receiving the bulges on both ends of the workpiece and further slippage of the workpiece relative to the radial contacts. After electronically stops the voltage supply to Saratovka and landing cylinders 3 polyurethane 4 and end pins 5 are returned to the original position. When the contacts 5 are separated from the product 34. Then the product 34 is released from the clamping cylinders 11 and the upper radial contacts 8 and removed from the device and the pneumatic cylinders 21 return poluchaeti 6 to its original position to clamp to polyurethan 4. Then the cycle resumes.

The advantage of this device is the lack of power cylinder blocks lower radial contacts. This simplifies the design. The advantage of the device also is you (nuts 19) are outside of the device, filled transformers and singatoka. This simplifies maintenance. The advantage of the device is that due to the absence of the power cylinder blocks lower radial contact significantly reduces the height of a loading and unloading zone of the device. It also simplifies maintenance. So in the device made in accordance with the prototype, the blocks of the lower radial contacts were applied power cylinders with a diameter of 150 mm and height of a loading and unloading zone from the floor level was 1250 mm, which required special elevating devices for the operator and complicated service while working electrofishing device in combination with a stamping device. The device, made in accordance with the offer, no power cylinder blocks of the lower radial contacts made it possible to reduce the height of a loading and unloading zone up to 1000 mm and provide the operator at ground level. The advantage of the device is also quick changeover when working with workpieces of various diameters and lengths. It provides easy access to the elements of height-adjustment of the lower radial contacts and the ability to move United in accordance with the prototype, electrolyzable suffered only blanks with a diameter of 16.5 mm and a length of 1318 mm In the same device, made in accordance with the offer, electrolyzable are preparations of three kinds: diameter 16.5 mm with a length of 1318, diameter 20 mm, length 1285 diameter 22 mm, length 1436 mm
