RU1801695C - Device for bending ends of bucket bail - Google Patents

Description

11, its working surface is made in the same plane with the vertical wall of the groove and parallel to the movement of the bending heads 4 and 5.

The vertical wall of the frame 1 has windows 12 through which the ends of the double-armed levers 13 are pivotally mounted on the brackets 14, rigidly mounted on the vertical wall of the frame 1. The ends of the levers 13 are pivotally connected to the rod 15 and the housing of the pneumatic cylinder 16, while the opposite ends of the levers 13 cooperate with bending heads 4 and 5. To limit the working stroke of the levers 13 and bending heads 4 and 5, screws 17 are screwed into the stops 2 and 3.

The bucket 18 by means of the handle 19 is hung on the support 9, while the handle 19 is placed in the groove 10. The pneumatic cylinder 16 has a working cavity 20, the piston 21 is mounted on the rod 15 of the pneumatic cylinder 16.

The device operates as follows.

The bucket 18 is hung on the support 9. By the weight of the bucket 18 and using the fixing strap 11, the handle 19 is oriented. relative to the bending heads 4 and 5 parallel to the direction of their movement. Through an air distributor (not shown), compressed air is supplied to the working cavity 20 of the housing of the pneumatic cylinder 16. Under pressure of compressed air, the housing of the pneumatic cylinder 16 and the piston 21, rigidly connected to the rod 15, begin to move towards each other along the axis of the pneumatic cylinder 16, simultaneously turning levers 13, which are widely connected with them, around the hinges of the brackets 14 in opposite directions. The second ends of the levers .13 interact simultaneously with the bending heads 4 and 5, moving them in opposite directions, while the fixing prisms 6 (made in the form of grooves) capture the ends of the handle 19 and move with them, choosing a gap before contact with the stops 2 and 3.

With further movement of the bending heads 4 and 5, which is limited by the interaction of the levers 13 with the screws 17, the final folding of the ends of the bucket bow is completed. When bleeding compressed air with an air distributor

the bending heads 4 and 5, the lever 13 and the housing of the pneumatic cylinder 16 return from the working cavity 20 of the pneumatic cylinder 16 under the influence of the return spring 8, the return spring 8 provides a force closure of the bending heads 4 and 5 with the ends of the levers 13.

The use of the proposed device can reduce the intensity

and power consumption of the device, reduce compressed air costs.

At the same time, productivity increases, because there is no need to manually orient the bow of the bucket relative to

bending heads
