Description

one

The invention relates to the field of mechanical engineering and can be used in correctly-cut automatic machines.

A receiving device of a right-cutting automaton is known, consisting of a guide channel, the lower part of which is covered with a plate along the entire length, and a spring-loaded stop is placed in the channel, which interacts with the cut wire and acts by mechanical connection on the cutting mechanism and the mechanism for removing the plate opening the channel for remove the cut wire.

In order to improve the cutting accuracy and reliability of the proposed device, the movable stop is made in the form of an L-shaped pusher, one arm of which is placed in the hole of the movable element mounted coaxially with the fixed element in a sleeve parallel to the shtange mounted with the possibility of adjustment movement along the guide channel, In this case, a fixed adjustable stop interacting with it is provided in the guide channel successively behind the movable stop.

FIG. 1 shows a part of the proposed receiver, general view; in fig. 2 is a cross section along A-A in FIG. one; in fig. 3 is a longitudinal section along the BB

FIG. 2; FIG. 4 is a cross-section along BB in FIG. one.

The receiving device is mounted on racks 1 installed on the foundation and interconnected by shaft 2. In the upper part of the racks there is fixed the pole 3 with a direction; channels 4 and 5 (channel 5 for a wire of larger diameter; when reconfiguring for a segment of wire of larger diameter

the rod 3 is rotated and secured so that channel 5 is at the bottom). The shaft 6 serves to secure the turntable 7 on it, which is made of separate sections. Each section is secured to shaft 6 by

brackets 8 and screws 9 and 10. Turning bar 7 closes the guide channel 4 but the entire length of the cut wire.

In the guide channel 4, a movable stop 11 is made L-shaped, the cross section of one arm 12 corresponding to the channel cross section, and the second arm 13 extending from the guide channel is installed in the aperture of the moving element 14 of the contact switch. The fixed element 15 of the contact switch through the insulating sleeve 16 is installed in the sleeve 17 n connected to the electrical circuit of the cutting mechanism by the wire 18. The movable element 14 is pressed against the fixed element 15 by the spring 19, which

also keeps the movable stop 11 in the extreme position. For pre-moving and movable element 14 from protrusion 6 of sleeve 17, a projection 20 is provided, which is included in the slot 21 of the sleeve. The sleeve 17 is attached to the guide channel 4 by means of clamps 22. The fixed stop 23 is fixed in the guide channel 4 by means of the clamp 24.

When setting up the device, the fixed stop 23 is installed at the end of the stroke of the movable stop 11, but not too close to the shoulder 13 of the movable stop, since in this case the wire to be cut will bend. The movable stop 11, the sleeve 17 and the fixed stop 23 can be installed anywhere on the length of the guide channel, depending on the length of the wire to be cut, for which the corresponding section of the turntable 7 is moved to the upper idle position I. The screws are then loosened. 9, and the screws 10 are led out of the holes in the shaft 6. After turning the brackets 8 to the upper position I, the screws 9 are tightened. When readjusting to a wire of a different length, the stops 11 and 23 and the sleeve 17 are removed, and the turn bar 7 returns to its working position and stops on the shaft 6 with a screw 10.

The device works as follows.

The wire moving in the guide channel 4 encounters a movable stop 11 mounted at a certain distance from the cutting mechanism and moves it, overcoming the resistance of the spring 19. At the same time, the moving element 14 moves away from the fixed element 15 of the contact switch, and the electrical circuit opens, resulting in in action mechanism of cuts. While the switch is triggered and the cutting knife approaches the wire, the latter continues to move in the guide channel and moves further the movable stop 11 until the shoulder

13, the movable abutment rests against the stationary abutment 23, after which the wire section and rotation of the shaft 6 with the securing sections of the pivoting plate 7 in position II begin.

Turning, the bar 7 opens the guide channel 4 from the bottom, and the cut wire falls out, after which, under the action of the spring 19, the movable cartridge 11 returns to its original position, and the movable element 14 again closes with the fixed element 15 of the switch. The cutting knife also moves to its original position, the shaft 6 is rotated, and the turning bar 7 closes the guide channel 4. The device is again ready to receive and cut the wire.

Subject invention

A pick-up device of a leveling machine, containing a rod mounted on the frame with a guide channel made in it, a rotating bar restricting the channel consisting of a set of removable sections, a movable spring-loaded stop placed in the channel, as well as an electric switch that interacts with the cutting mechanism movable and stationary elements, characterized in that, in order to improve the cutting accuracy and reliability of the device, it is equipped with a sleeve located parallel to the rod, mounted possibility of adjusting movement along the guide channel, and the movable stop is in the form of L-shaped pusher arm is taken by one of the movable member in opening electric switches mounted coaxially with the fixed member, wherein a channel nanravl yuschem pos. Consistently with a movable stop, a fixed adjustable stop interacting with it is provided.
