SU721134A1 - Stand for rolling radiator panels - Google Patents

Description

I

The invention relates to the processing of metals by pressure, in particular to rolling stands, and can be used in the manufacture of panel radiators.

The famous rolling stand for radiator panels, containing profile work rolls and drive of profile work rolls, associated with the axes of the profile work rolls by cardan shafts and the angle adjustment mechanism; I. Alkov.

The disadvantage of such a stand is that the angular adjustment of the profile of the work rolls is carried out using bolts within the limits of the size of the slots, which leads to inaccurate adjustments.

The aim of the invention is to improve the technological and operational stands by ensuring the accuracy of the angular adjustment of the rolls.

To achieve this goal, the mechanism of angular adjustment of the rolls is made in the form of single-stage worm gearboxes according to the number of profile work rolls, with 40pDq4JJoe wheel every

the gearbox is fixed on the axis of the corresponding profile work roll, the casing is rigidly connected to the corresponding drive shaft, and the worm is mounted in the casing

FIG. 1 shows a general view of the proposed rolling stand for radiator panels 6c {in FIG. 2 - worm gear (remote element I); in fig. 3, the chervna transmission, on the arrow A in FIG. 2} in FIG. 4 is a diagram of the preparation of radiator panels.

The cage for rolling the radiator panels contains a drive 1, to the output shafts of which four cardan shafts 2 are attached. At the opposite ends of the cardan shafts 2, a worm gear 3 is mounted connecting the shafts 2 with two pairs of profiled work rolls (4 and 5, 6 and 7),: found in the frame. Housing 8 to 1 each worm gear 3 rigidly connected with half coupling 9 of the corresponding shaft number 2, W Yu shaft installed, in which | nycax 8, a worm gear 11 is fixed on the axes 12 of the corresponding profile work rolls 4-7.

The cage works as follows.

A round moment from the drive 1 through the cardan Arles 2 onto the housing 8 9 through the engagement of the worm gears S on the axis 12 of the profile work rolls 4-7, 8. The profile work rolls begin to rotate and, in this case, the worm to the 1st U and the worm wheel 11 are fixed relative to each other.

When the profiles of the rolls 4 and 5, b and 7 displace each other, the stand is stopped, the rolls are moved apart and the worm is turned to the corresponding roll 10 in one direction or another, the profiles of the rolls (4 and 5, 6 and 7) are combined . When the radiator panels are displaced relative to each other when they are superimposed (see Fig. 4), they are adjusted in a similar way. Using the worm gears, turning one niapy rolls, for example, 6 and 7 relative to another pair of rolls 4 and 5.

The presence of worm gears on each carda shaft will allow infinite adjustment to combine the profiles of the rolls of each pair and re, pair the rolls with each other to eliminate the displacement of the radiator panels when they are superimposed on each other.

:: to a borka and adjustment, and at operation of a cage. This eliminates metal impulses during molding, reduces shaft-Aoe wear, eliminates defects in non-alignment of radiator panels and leads to an improvement in the quality of manufactured radiators.
