Description

eleven

The invention relates to the engineering industry and other industries that use equipment for electrical contact heating used in heat treatment of rolled products.

The purpose of the invention is to increase the productivity of the unit during the heat treatment of a single-rolled profile steel.

1 shows a unit for electrocontact heat treatment of rolled products, top view; figure 2 - section aa in figure 1; in FIG. 3, view B in FIG. I; figure 4 is a view In fig.Z; figure 5 - section GG on fig.A; figure 6 - section dd in figure 4; figure 7 - section EE in figure 4.

The proposed unit contains a heating device 1 for heat treatment 1, a device 2 for loading products 3 onto contact carts 4. Truck 4 is provided with an average contact 5 and extreme contacts 6 with drives from hydraulic cylinders, normal to the longitudinal axis of the heating device 1 for heat treatment.

The heating device 1 for heat treatment is provided with clips 8 and pockets 9 for collecting the processed products 3.

The loading device 2 for the cross-feeding of products 3 is made in a vizhe floor wheeled machine and is equipped with consoles 10 with cheeks 11. Four bearing assemblies 12 are mounted on the cheeks 11 for fastening the shafts 13 and 4. The shaft 13 is equipped with a tilter, erected in the form of two shoulders 15, planted on the shaft with ptonki. The shaft 14 is equipped with a tilter made in the form of a two-armed lever 16, Levers 1 5 and 16 are interconnected by a hydraulic cylinder 17. Cranks 18 connected by a pair of torsion bars 19 are attached to shuhronny rotation on shafts 14 and 13.

Sheki 11 consoles 10 are rigidly connected by cross-pieces 20 and 21, and cross-pieces 21, c. the turn is fixed between each other by the strips 22. In the rectangular opening formed by the crossbars 21 and the strips 22, the shank of the receiving table 23 is inserted. Meldu has two pairs of crossbars 20 installed and fixed two spring-mounted glasses 24. For adjusting

The treads 25. serve in the slot of the receiving table 23. A stop 26 is installed in the vertical plane, in the groove of which the levers 27 and 28 are inserted at one end and fixed on the shafts 13 and 14, respectively. The lever 27, free from the groove of the anvil 26, is connected through the hub 29 to the crank 30 via the hub 29. Similarly, through the hr 31 the lever 28 is connected to the elongated axle of the hydraulic cylinder 17.

The loading device 2 is mounted on a rail track 32, fitted with an abutment 33. A tilter 34 is installed for the preliminary orientation of the product, and the installation is equipped with a capacity of 35 for collecting coolant.

Agr egat works as follows.

The cargo magnetic crane of the product 3 is fed to the loading device 2. If, if the articles 3 being transported by the crane are not designed as necessary for laying, the products are preloaded into the tilter 34, which orients the half profile in different directions with its thickened edges f FIG. ).

The orientation of the asymmetrical profiles is determined by the design of the contacts 5 and 6 of the heating device 1 for heat treatment.

When lowering the next product 3 on the console 10, the end of the product must be brought to the stop 33.

After laying the appropriately oriented products 3 onto the folding tables 23 and the lowered levers 15 and 16 (tilters), the hydraulic cylinders 17 are turned on. The rods of the hydraulic cylinders 17 extend and the upper parts of the levers 15 and 16 of the tilters rise. At the same time, the double-arm levers 27 and 28, which are seated on shafts 13 and 14, which at one end enter the groove of the stop 26, push the stops upwards, and the receiving tables 23, which are in contact with the springs installed in the cups 24, make a limited vertical movement so much how many allow them to hold the rod 25, providing saTH / wcv springs.

they are lifted up by the amount of movement of the receiving tables 23. The sliding stops 26 do not allow the items 3 to slide off the levers 15 and 16 as they turn, (in Fig. 3, by convention, the working position of the items is shown).

After forming the rods of an asymmetrical bulb with a loading device in the bag on the rib, the loading device 2 starts moving towards the heating device 1 and ends moving when the package axis coincides with the longitudinal axis of the heating device 1.

After stopping the loading device 2, the hydraulic cylinder 7 turns on to close the contact carts 4. The latter move to the extension of the loading of the loading device 2 of the arms of the 3 rods j and clamp them in the conductive contacts 5 and 6. This product 3 is released from the loading device 2 as follows in a way. At the command, the hydraulic cylinders 17 are drawn into the hulls, the upper parts of the levers 15 and 16 return to their original horizontal position, and the sliding stops 26 are lowered and at the end of the stroke the receiving tables 23 are lowered.

In this case, gaps are formed between the contacts 1 in the contacts 3 and the receiving mechanism of the loading device 2, which allow the consoles 10 of the device 2 to output the consoles with the devices installed on them, I do not cling the products.

After the charging device 2 leaves the heating device 1 for heat treatment, a command is issued to turn on the current to heat products 3, and a load device, a command to feed the next batch of products 3.

After termination of heat treatment of products 3 in device 1, hydrocyliners 7 unclench contacts 5 and 6, carriages 4 are discharged to their initial position, and thermally processed products for mucus 8 fall into pockets 9. By this time the loading device is already preparing another package from two products 3 and begins to move in the direction of the heating device 1 for heat treatment. The cycle is repeated. After the pockets 9 are filled with heat-treated products, they are removed by the workshop crane.

The proposed device allows, in comparison with the known, to mechanize the process of feeding the rolled steel, in particular the bulb, and, thus, to increase the productivity of the unit itself.
