Description

The invention relates to mechanical welding equipment and can be used in devices designed to provide access to both surfaces of sheet metal parts during the welding process.

The purpose of the invention is to ensure the reliability of turning of sheet parts of various configurations.

FIG. 1 shows the tilter, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section, B-B in FIG. one; in fig. 5 is a section of YYD in FIG. 2

The lever-book tilter consists of left 1 and right 2 frames, feed levers 3 fixedly mounted on shaft 4, hingedly fixed in supports 5 mounted to the foundation, and receiving levers 6 rigidly fixed on the tubular shaft 7. For transmission For the moment, the feed 3 and receiving 6 levers are pivotally connected by means of shatuns 8 and a common joint 9 s. a slide actuator 10 rotates the levers consisting of a hydraulic cylinder 1.1, on the rod of which a slider 10 is fixed, moving along the guide 12. The feed 3 and receiving 6 levers constitute a system of pivoting levers that, with the rotational drive of the levers, have a common axis 13 turning. They are rotated by an additional actuator 14, the brush of which is pivotally connected to the lever rotation actuator 12, and its body is hinged to the foundation. The sequence of operation of the lever-lowering knob (raising, turning, lowering) is carried out by means of limit switches and rulers.

To fix the sheet parts on the feed 3 and receiving 6 levers, the housings 15 are fixed, in which the electromagnet 17 is mounted on the springs 16 with the possibility of deviating from its vertical axis, thanks to the ball bearing 18, as well as the limit switch 19 and the ruler 20. To prevent the workpiece from moving to the center of rotation, retracting stops 21 are mounted on the feed levers 3, and stationary stops 22 are mounted on the take-up levers 6.

The lever book tilter works as follows.

In the initial position, the feed 3 and receiving 6 levers are located below the level of frames 1 and 2. An assembled sheet blank is laid on the right frame 2, which is boiled on one side. After this, the sheet blank is turned over. With the beginning of the rotation of the feeding arms 3 from position a to position b (Fig. 1), electromagnets 17 are activated, which fix the workpiece. The workpiece rises and turns

with around axis 13 counterclockwise. At the same time and synchronously with the rotation of the feeding arms 3, the receiving levers 6 are rotated clockwise, moving towards the feeding arms until they converge with them in an inclined position b. This movement of the levers occurs under the action of the hydraulic cylinder 11 during the movement of the slide 10 upwards. At the approach of the applicants 3 and the adoptive 6 levers to the position b, the stationary stops 22 squeeze out the spring-loaded set stops 21 and fit under the workpiece. In position b, ruler 20 interacts with limit switches 19, from which a command is received to turn on an additional drive 14, by means of which it rotates from position b to position at an angle of about 12 °, and also to turn on electromagnets 17 on receiving levers 6 and turning them off on the sub levers 3. The sheet billet goes over the vertical, fits onto the receiving levers 6 and is fixed by electromagnets 17. The installation of electromagnets 17 on the springs 16 and the possibility of deviating them from their vertical axis They provide a tight pressing of the electromagnets 17 to the plane of the sheet. After that, the next limit switch is turned on, which gives a command to lower the feed 3 and receiving 6 levers. The blank from the position to the bottom is lowered to the position g and placed on the frame 1, on which the second side of the blank is welded, after which it moves away from the zone of the lever-book turner.

The application of the invention makes it possible to improve the working conditions and the reliability of the work of the tilting device by ensuring that the sheet parts of various configurations are securely fastened and that they remain in position during casting.
