 The invention relates to a technique I local heating of the metal and may

to be used for heat treatment

 welded klev and longitudinal ipv - bodies of rotation, for example rolls of rolling mills.

The purpose of the invention is to automate the process of changing over the installation to various sizes of heated I products.

I Figure 1 shows the installation of local heating, a general view; figure 2 - the mechanism for setting blocks of heating units.

I The installation for local heating contains a base 1 mounted on an I trolley 2 mounted on rails 3 with a telescopic console 4 fixed on it and a radial movement mechanism 5 mounted on it. On console 4, six blocks are pivotally connected I; heating units, of which blocks 6 are located on opposite sides of the axis of the console 4, mounted on it; the hinge 7 is equipped with rigidly fixed levers 8 that have the ability to move in the direction I, the first radial movement of the cantilever, from the actuator 9 mounted on the cantilever 4.

 The hooks 8 are connected to a drive of 9 wines: Tami 10, passing through the nuts 11,; installed in the slots 12, is made; on the levers 8. The blocks 13, the second i from the axis of the console 4, are connected to it by rods 14, which are fixed to the console 4 below the axis of the hinge 7 by one end of the 15th end and to the block 13 of the hinge to the other end 16 17, linking this block to the previous block 6. All subsequent blocks are connected in pairs through one pair in the same way.

The installation works as follows.

The cart 2 with the console 4 mounted on it is moved along the axis of the heated product 18 to the place where it is necessary to produce heating. Then the mechanism 5 of the radial movement of the console 4 brings the blocks of heating units closer to the item 1B. After this, the blocks of heating units are adjusted to the diameter of the workpiece. The actuator 9 rotates the screws 10, which push the levers 8 apart in the direction perpendicular to the radial

move the console. Lugs 6 under the gift of levers 8 rotate around 5 g of hinge 7, approaching tangentially to the surface of product 18. Block 6 through hinge 17 drives block 13, while ta 14 turns the latter around hinge 17. All subsequent blocks under the action of The preceding links and rods are turned around, covering the heated product 18. To adjust the blocks of the heating units to a larger size — you need to drive the screws 9 in the opposite direction with the actuator 9. It is possible to re-install the installation to different diameters of the heated products. produce without disconnecting blocks of heating devices. The range of sizes of heated products from 700 to 3000 mm.

In the transport and maintenance position, the heating blocks 6 and 13 are collapsed into a polygon, the posterior console 4 is assembled and its base is rotated so that the common axis becomes horizontal at a distance of 1500 W-l from the floor.

Claims (1)

Thus, this installation allows you to perform changeovers on different diameters of heating products automatically and without disconnecting the blocks of heating units.
