Description

one

The invention relates to a machine tool industry, can be used in the supply of lengthy parts to machines of various technological purposes, including a pipe bending machine, and is an improvement of the device according to aut. No. 625907

The purpose of the invention is to increase the reliability of the device by increasing the accuracy of positioning of the parts, as well as reducing the production noise during its operation.

FIG. 1 shows the proposed device, a general view; FIG. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The feeding device for the pipe bending machine contains a base 1, a feeding tray 2, a cutter made as mounted on axis 3 with the ability to rotate the curved double-shouldered levers 4 and fixed stops on the same axis stops 5 and 6. The hooks 4 are hingedly connected with lever 7 with the rod of the power cylinder 8, and the latter is also connected to the lift 9, made in the form of a hinged lever, summing mechanism.

On the lifter 9 there is a roller table 10 with screw grooves 11, on its rollers there are connected gears 12 with fixed rails 13 fixed to the base 1, adjustable lugs 11 fixed on the rollers of the roller table 10 and fixed relative to the holder of the elevator 9 prisms 15 for positioning parts and limiting

16, fastened to its side of the clip. To regulate the stroke of the power cylinder 8, a threaded support sleeve 17 is provided, mounted in its housing coaxially with the rod, with the possibility of changing its position relative to the housing.

The device works as follows.

In the initial position, the lift 9 is in the lower position, and the part is positioned between the stop 5 and the figure lever 4. When receiving the load command, the piston rod of the power cylinder 8 is pushed forward, set in motion the lever system of the lift 9, as well as the levers 4 and 7, the latter lowering below the level of the feeding tray 2, allowing the parts to be moved up to the stop 6.

When the lift 9 moves upwards, the gears 12, rolling on the fixed rails 13, rotate the rollers of the roller table 10, and its screw grooves, gripping the part, move it in axial and transverse directions to the stops 14 and 16. At the end of the movement the detail sinks into the fixed prism 15 in a strictly defined position.

After the part is captured by the robot or the stem, the piston rod of the power cylinder 8 is removed, the lift 9 is lowered, and the next part is moved by the lever 4 until it stops 5 and the paddle is repeated.

To adjust the height of movement of the elevator 9, a support sleeve 17 is used, limiting the stroke of the power cylinder 8.
