Изобретение относитс к обработкеThe invention relates to the processing

металлов давлением, в частности к конструкции профилегкбочных станов, предназначенных дл работы со сменными профилировочными блоками, и может быт использовано при производстве гнутых профилей.metals by pressure, in particular to the design of profile mills, designed to work with interchangeable forming blocks, and can be used in the production of bent profiles.

Известен привод рабочей клети, содержащий шестеренную клеть, валы .которой соединены с фланцами валов рабочей клети посредством телескопических шпинделей, и механизм автономного поворота шпинделей 1,The drive of the working stand is known, which contains a gear stand, the shafts of which are connected to the flanges of the shafts of the working stand by means of telescopic spindles, and the mechanism for the independent rotation of spindles 1,

Однако конструкци данного привода сложна и громоздка.However, the design of this drive is complicated and cumbersome.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Поставленна цель достигаетс тем, что механизм автономного поворота св зан со шпинделем одного из валов рабочей клети, а шпиндель второго вала рабочей клети св зан с валом шестеренной клети с возможностью свободного углового хода. Шпиндель, имеюишй воз-The goal is achieved by the fact that the autonomous rotation mechanism is connected with the spindle of one of the shafts of the working stand, and the spindle of the second shaft of the working stand is connected with the shaft of the gear stand with the possibility of a free angular stroke. Spindle, have

можность свободного углового хода, св зан с валом шестеренной клети посредством закрепленной на валу шпонки, а ширина шпоночного паза, выполненного в шпинделе, больше ширины шпонки.the possibility of a free angular stroke is connected with the shaft of the gear stand by means of a key fixed on the shaft, and the width of the keyway made in the spindle is greater than the width of the key.

На фиг. 1 показан привод рабочей клети, обший вид; на фиг. 2 - разрез А-А на фиг. V, на фиг. 3 - пример конкретного выполнени механизма автономного поворота фланца шпиндел , местный вид.FIG. 1 shows a drive of a working stand, a general view; in fig. 2 shows section A-A in FIG. V, FIG. 3 is an example of a specific implementation of the mechanism for autonomous rotation of the spindle flange, a local view.

В данном примере рассматриваетс одна из клетей сменного блока, число которых может быть 1О и более.In this example, one of the stands of an interchangeable block is considered, the number of which may be 1O or more.

Claims

The drive of the working stand of the replaceable profiling unit (Fig. 1) consists of two spindles 2 and 3 connecting the gear stand 4 to the shafts 5 of the working stand. The syin of spindles has an autonomous rotation mechanism (Figs. 2 and 3), consisting of a globoid screw in, placed in a carrier 7, and a worm wheel, made in the form of a spindle flange. The flanges 9 and 10 have slots for transmitting rotation to the shafts. 5 working stand The carrier 7 is mounted on the plug 11. The spindle 3 has a free angular stroke, the value 06 of which is determined by the difference between the width of the keyway of the flange 12 and the key 13 mounted on the lower 14 gear stand. To eliminate hard blows, elastic pads 15 are provided. The profiling unit 1 and gear stands 4 are installed on the base 16 of the bending mill. The drive connection is as follows. After block 1 is installed on the frame 16, the slots of the shaft 5 and the tongue 9 of the spindle 2 are combined by turning the worm Ka6. lower rolls, as a rule, increase as the profiled metal moves. Since the metal moves at a constant speed, the lower rollers rotate somewhat slower as the main diameters increase, and the gap between the key 13 and the keyway of the pin 12 is selected. After that, the lower roller is put into normal operation. It should be noted that at the time of selecting the gap 06 the process of profiling will occur in the usual way, due to the drive of the upper rods, while this time is very short. The use of the proposed drive makes it possible to speed up the process of connecting the mill gear stand to the shift profiling unit with the filled tape, and also eliminates the adjustment of the block when it is reinstalled in the mill. In addition, the use of spindles with a free angular stroke significantly reduces the number of actuator adjustments. Claim 1. Drive of a working stand, mainly of a roll forming mill with interchangeable shaping blocks, containing a gear stand, the shafts of which are connected to the flanges of the shafts of the working stand by means of telescopic spindles and an autonomous spindle turning mechanism, characterized in that rotation is connected with the spindle of one of the shafts of the working stand, and the spindle of the second shaft of the working stand is connected with the shaft of the gear stand with the possibility of a free angular stroke.

2. The actuator according to claim 1, characterized in that the spindle, having the possibility of a free angular stroke, is connected to the shaft gear by means of a key fixed on the shaft, and the width of the keyway embedded in the spindle is greater than the width of the key.
