 54) INSTALLATION FOR TRfJMH FCKOO L PAbCTlV DIPIN NyH YDDG, (57) The invention is outgoing: t -.- n (0th processing of products with inductive roar and thermo-length of idiom-edmy / moby configuration in cross-section The purpose of the invention is to increase productivity by reducing the time per vc: production of products of various sizes and pauses between operations. Installation (Y contains multi-heater 1 (I) for heating for quenching and multi-turn inductors for tempering. All A are installed in parallel on a common plate 5 posted on with tannin 6. U contains established with

the possibility of moving the carriage 10 with rows of side racks 11 and 12. On which support devices are placed in the form of a rod 13 fixed on racks 11 and passing through inductors or a quenching chamber, and fixed on rack 12 of the lodgment 14 The free end of each gang has a base lodgement 16. The distance between the cradle is adjusted. For shifting the products 17, a lift 18 with a carriage 19 g mounted on it is supported 20. A carriage with a lift is placed on the base 21 of the carriage 10 and have the possibility of horizontal displacements perpendicular to the longitudinal axis of the inductors. Installing a carriage with a lift on the base of the cart shortens the duration of pauses when moving products of any configuration. The lodgements and the multiple inductor allow processing products of any length and configuration, shorten the installation time of the products in the lodgements between operations, which improves the quality of processing. 4 il.

under the common plate 5 The carriage 19 is made with six rows of supports 20, five of which are located in the initial position under each supporting device

under item 17

At the end of the quenching chamber 7, the locking device 22 of the cover 15 is fixed. Longitudinal movement of the carriage 10 is carried out by an actuator 23 from a rack

0 caddies 24 To limit the longitudinal course of the trolley 10, shock absorbers with stops 25 are mounted on the bed 6

To supply the product 17 for heating and further processing, a conveyor5 is used. The accumulator 26 is installed in front of the inductor 1. The conveyor 26 has its own supporting devices 27 for placing the product 17 liters of correction and position before installing them on the conveyor 26. mechanism 28

At the discharge position behind the inductor 4, a cooling tank 29 is mounted on a second mounted feeder 30 serving to receive the product 17 after tempering

5 inductor 4 and transferring it to a chain conveyor 31 located on tank 29, which unloads the product after complete cooling into a container (not shown)

The installation works as follows.

0 eom

Products 17 to be heat-treated are placed in a horizontal POPPZHRNII on the supporting devices 27 of the connier of the accumulator 26 and are fed to the inductor

5 1 (Ы loading positions before applying to the inductor the position of the product 17 by the correction mechanism 28

The carriage 19 makes a working stroke in the direction of the conveyor 26 and the first row of its supports

0 20 is located under the product is located at the loading position. Lift 18 lifts up the carriage 19 when moving up, and the slide 17 is gripped by the supports 20 Then Xcfcg 19 moves to the direction of the inductor 1, the product 18 is lowered to it and the product is lowered. on the lodgements 14 and 16, support the well-being of the first inductor-pre-heating inductor 1

0 Turn on the hdd drive 23 with the rack gear 24, the telehandle 10 moves to the left (Fig. 3) and supplies the product to the inductor 1 Heating is turned on.

5 the initial position unloading the product from the inductor 1 with a lift 18 and the carriage 19 the preheated product 17 is transferred to the final heating position. It is loaded into the inductor 2 (similar to loading into the inductor

1 preheating). After the final heating, the carriage 10 takes the heated product 17 out of the inductor 2. The lift 18 with the carriage 19 operates, the product 17 is transferred to the cradles 14 and 16 before the quenching chamber 7, the Cart 10 takes the product to the chamber 7, while the cover 15 tightly closing the chamber 7 by means of a locking device 22. From the coolant station (not shown) a stream of liquid, for example water, is passed through the chamber 7. The product 17 is quenched by compressed air. Then the water from chamber 7 is displaced, chamber 7 is opened, and the quenched product 17 is brought to its initial position by carriage 10. Further heating of product 17 in inductors 3 and 4 of tempering (as well as loading-unloading) occurs in that the same sequence as in inductors 1 and 2 of heating for quenching,

At the end of the holiday, the carriage 19 transfers the part to the supports of the frame of the feeder 30 of the cooling tank 29. The frame of the feeder 30 lowers the product 17 into the tank 29, dumps it onto the chain conveyor 31. Moving in the tank 29 on the conveyor 31, the product is cooled. Conveyor 31 takes it out and dumps it into a container (not shown).

The installation of a trolley installed with the ability to move the adol axes of the inductors and the quenching chamber, with the rods of supporting devices passing through them, ensures the loading and unloading of products into the inductors closed in cross section and the quenching chamber from the end, which is necessary for the heat treatment of long products, rotational bodies to obtain high quality heating and quenching. Moreover, the possibility of placing the products in the cradles of supporting devices, and not in the center, as in the prototype, makes the installation multi-item.

Placing the elevator on the base of the trolley and so that the supports of its carriage are between the cradles of the supporting devices of the trolley when they are located and the supports of the carriage in parallel planes that coincide in the upper position of the elevator, and in the lower one allow

the elevator to go under the base on which the inductors and the quenching chamber are installed, makes it possible to eliminate the intersection of two mechanisms (trolley and elevator) moving during loading and unloading

in mutually perpendicular directions. Such a constructive implementation does not require readjustment during loading and unloading, and in particular, when changing the sizes of products. Processing on such an installation occurs without long pauses, which contributes to improving the quality of processing. At the same time, quick installation into cradles of supporting devices allows processing products of any configuration and

any length (due to the possibility of adjusting the distance between the lodgments).
