Description

(54) RIGHT MACHINE

This invention relates to the processing of meta-clutches with pressure.

A known machine is known, containing two rows of regular roars mounted on a frame in a chessboard, a mechanism for vertical movement and change of ropik's pitch, as well as drive of at least one ropik made in the form of an electric drive connected with a roar through a system of gears. co p l.

Each mechanism for the vertical movement and change of the pitch of the rollers is discharged in the video.two separate devices; Wormhole - for changing position

rollers in a vertical plane and a gear rack for moving the rollers along the straightening axis. However, not every video has both of these devices at the same time. Therefore, it is not possible to edit products of a wide range of thickness on a well-known machine.

The aim of the invention is to expand the technological capabilities of the machine.

This goal is achieved due to the fact that each mechanism for vertical movement and change of roller pitch is made in the form of two one-arm pivotally interconnected, with each roller and bed frame, and the hinges of the connections are aligned with the shafts of the gear wheels of the drive, and the electric motor of the drive is fixed on the frame .

Claims (2)

FIG. 1 shows the kinematic scheme of the correct machine; pas figs. 2 is a kinematic diagram of a lever mechanism for vertical movement and change of the pitch of the rollers; in fig. 3 is a kinematic diagram of an individual drive of a separate roller for a straightening machine; on 4ig. 4 shows a kinematic diagram of an individual drive for a single roll for a leveler; in fig. 5 is a diagram of the arrangement of the gears of the drive for the seven-roller machine in FIG. 6 shows the arrangement of gears for the drive of an eight-roll machine 1.1; in fig. 7 - section A-A of FIG. 6. The correct machine contains two rows of correct rollers placed on the frame 1 2. Each correct roller is provided with a double-lever mechanism for changing the pitch and lateral movement, the levers 3 and 4 of which, by means of the hinged joints 5, 6, and 7, are associated respectively with the bed, with each other and with the correct roller. Fixing the correct roller in a predetermined position is carried out with the help of fixing devices 8. The hinged connections of the double-lever mechanism are located coaxially with the shafts of the gear wheels of the individual drive of the correct roller. With slight straightening forces, shafts 9, 10 and 11 can be simultaneously used as load-bearing elements for articulated joints. The gears 12 of an individual drive can be enclosed either in a hinged body, which are the levers 3 and 4 of the double-link mechanism (see Fig. 3), or in the housings of individual gearboxes 13 and 14 (see, Fig. 4). The correct rollers 2 of the leaf-leveling machine can be provided with support rollers 15. Individual rotation of the correct rollers (rollers) is carried out by means of motors 16. The drive for changing the pitch and lateral movement is driven by a hinge screw connected to each arm 17. a self-driven drive or manually nuts 18, the front part of which forms, in combination with the sleeve 19, a thrust BEARING, the Sleeve 19 is hingedly connected to the bed or to one of the levers. The screw and, consequently, the correct ropik (roll) in the required position are fixed using a clamp made, for example, in the form of a brake 20. During the editing process, the screws 17 can absorb the force of the straightening, thereby providing the necessary rigidity of the roller bearing (roll ) .. In the pistol-dressing machine, the drive can be made with the help of the driven gears 21 and 22, located respectively on the left and right sides of the machine, in a shakhmatny order, with the distance between adjacent tooth gears equal to three times alkov. Such an arrangement of gears allows, at a minimized distance between the rollers, to ensure the transmission of maximum torque to them. To edit workpieces with significantly different cross-sectional dimensions, a change in the pitch and diameter of the rollers (rolls) is necessary, as well as the transverse adjustment of the position of the pots (wipes) relative to the axis of the straightening. With the help of two pairs of screw 17 - nut 18, the levers 3 and 4 are rotated, providing in a wide range control of the pitch and (or) the transverse position of the correct pon, iKa (roll). A change in the position of the mouth (vagas) is made while the engine and the drive shaft are stationary relative to the frame. The correct machine works as follows. After presetting the rollers (rolls), the straightened material is fed into the machine, where it is subjected between the rows of rollers (rolls) to alternating elastoplastic bending. The proposed correct machine provides for editing profiles of various co.jTaMeHTa. Claims of the invention A correct machine comprising two rows of correct rollers mounted on a frame in a slanty order, mechanisms for vertical movement and change of the spider rollers, as well as driving at least one roller made in the form of an electric motor connected to a roller through a system of gear wheels , characterized in that, in order to ensure the editing of products of different thickness, each mechanism of vertical movement and change of the spider rolls is made in the form of two one-shoulder arms hinged together, with each It is equipped with a roller and a frame of levers, the joints of the joints are located with the shafts of the gear wheels, and the drive electric motor is mounted on the frame.
