Description

one

This invention relates to chemical processing of rolled products.

A known line for the chemical treatment of rolled products, including baths located along the technological process, and mechanisms for the vertical and horizontal movement of the IC.

The disadvantage of this line is low productivity and high metal consumption of the structure.

Closest to the proposed technical essence and the achieved result is the line for the chemical treatment of rolled products, including the body located along the process of the bath with a lid and the mechanisms of vertical and horizontal movement 2.

However, the known line has insufficient performance due to the movement of subsequent rental points only after the mechanism of horizontal movement returns to its original position.

The purpose of the invention is to increase line productivity.

The goal is achieved by the fact that each horizontal movement mechanism is made in the form of rollers cantilever-mounted on each mechanism, and the line is equipped with baskets for accommodating rolled products that can be supported on rollers, the body is made with grooves, and the lid is rigidly connected to the console rollers and made with sidewalls placed in the slots of the housing, each mechanism for vertical movement is made

10 in the form of a vertical screw pair fastened in the housing.

FIG. 1 shows a line for the chemical treatment of rolled products, a general view, in FIG. 2 - the same, top view,

15 in FIG. 3 shows section A-A in FIG. 2; in fig. 4 is an enlarged view of the mechanism of vertical movement, section.

The line consists of a series of baths 1 installed along the

20 of the process, the mechanisms of 2 vertical and horizontal movement, podkvdego 3 and receiving 4 roller tables.

The mechanism of the screw movement consists of six screw lifts 5, united by a lid 6, which is rigidly connected to the console roller conveyors 7, the latter is rigidly attached to the lifting screw B and permanently engaged with the nut

30 9. A nut 9 is installed in bearings 10 mounted in a housing 11, and it is mounted rotatably through bevel gear 12 from a gearmotor 13. A rental basket 14 is installed on a mechanism for horizontal movement of rollers 15 mounted on shafts 16, which in their all are mounted in bearings 17 of the housing 7.

The rollers 15 are rotatably mounted from the gearmotor 18 via gears 19 and 20.

The cover 6 has a sidewall 21, placed in the grooves 22 of the housing 11.

The line of chemical processing of rolled products works in the following sequence.

The basket 14 with the rolled stock, the crane is placed with longitudinal bolts in the streams of the feeding roller table 3, and the rollers of the roller table do not rotate. After the lifting screws 8 together with the live rolls and telescopic cover b occupy the uppermost position on all baths, i.e. baskets 14 are lifted and an excess of working solutions will be drained from the rental, motors of gearmotors 18 simultaneously turn on and transfer rotation through gears 19, 20 and shaft 16 by roller 15, which move baskets 14 along the line from position to position.

After stopping the basket over the baths, i.e. when the end of the blocking switches shut off the motors of the geared motors 18, the drives 13 with the help of bevel gears 12, nuts 9 and screws 8 lower the baskets into the baths 1, while the hook 6 lowers to the lower position for the technological time specified by the time relay. In this case, at certain positions (depending on the technological process), the actuators 13 can be periodically switched on for raising and lowering during the technological time, which ensures the circulation of the solution in the package.

After the processing time at each position (in each bath) of the basket 14 with rolling, is lifted to the extreme upper position and maintained until the end of all technological operations. Then, the drives of the rollers 15 are turned on and the cycle is repeated.

The proposed device allows increasing productivity by 50% at the expense of increasing the lifting capacity of the lifting and transporting device without increasing its metal intensity, improving working conditions by reducing gas pollution over the baths, as the bath mirror is permanently closed by telescopic lids, and improves the quality of product processing due to the possibility of rocking separately in each bath.
