Description

f

The invention relates to devices for flexible beads per edge.

The purpose of the invention is to increase productivity by reducing set-up time.

Figure 1 presents the proposed machine plan; figure 2 - section aa in figure 1 (rotated).

The machine consists of a frame 1, on which case 2 with a cover 3 is installed. Axis 4 is placed in case 2, carrying a worm gear 5 in contact with a screw 6. clip 9 of the workpiece 10 and the clamping tool in the form of a block 11 mounted on the springs 12 can be adjusted by means of a nut 13. On the lower end of the rod 7 is fixed cam 14 with protrusions. Profile grooves 15 are made at the bottom end of the hollow axis to accommodate cam projections 14. A bending tool 16 is mounted on the frame. The template rotates from the drive of the engine 17, and the angle of rotation is determined by limit switches 18 and 19. On the frame mounted bracket 20 and the stop 21.

The machine works as follows.

The treated strip is placed on the brace 20, and its rear end abuts against the stop 21, which determines the distance to the bend of the strip. With

At this point, the strip passes under the pressure pad 1I, which is installed with a certain gap, ensuring the free running of the bending template. The clamping pad 11 is height adjustable

to set a predetermined gap Z. When the actuator 17 is turned on, the worm gear 5 rotates the axis 4, which with its grooves 15 comes into contact with the protrusions of the cam 14 and moves
