Description

one

The invention relates to the manufacture of narrow reinforcing meshes for reinforced concrete products.

Mechanisms are known for supplying transverse rods from a bunker to the electrodes of a machine for welding reinforcing seto to reinforced concrete products, containing a drive carriage mounted on the machine’s section with a tick-grip transverse rod.

However, well-known mechanisms, we do not have proper clarity and reliability in operation.

In order to increase the reliability of its work when applying mainly short rods on the frame: in the area of the bukker and welding electrodes. and releasing it under the electrodes of the welding machine.

FIG. 1 depicts the proposed fur. in fig. 2-section A-.4 in FIG. one; in fig. 3-mechanism, plan.

In the Guide / rigidly mounted on the frame 2 of the welding machine, with the help of the rolling bearings 5, a carriage 4 is mounted, carrying the axis 5 of rotation of the levers 5 and 7 of the tong tong. Lever, spring loaded S, DecA; 1 are cheeks 9 and JO.

The movement of the carriage 4 with the tong clamp is carried out by means of a // reciprocating movement from the drive of the longitudinal movement of the welded part of the frame () and not shown) on the lining 12 rigidly fastened to the carriage.

On the path of movement of the carriage with a pincer grip on the guide, lugs 13 and 14, corresponding to the position of the Bike 15 and welding zones 16, are located. When running on upara levers 6 and 7 tick clamp.

The slips are consumed.

The gap between the cheeks 5 and W at a certain diameter of the transverse rod is established by the finger 17.

Mechanism feed has a rod 18 and a longitudinal rod 19. The bunker is equipped with a pore 20.

In the initial position, the carriage 4 with a tong-shaped gripper is located under the slot: the bunker 15. At the same time, the lever 7, running onto the stop M and pressing the spring 8, retracts the cheek 10, increasing the gap between the cheek. rod 18 is placed between the cheeks.

From the beginning of the movement of the gi // in the direction of the welding zone 16 ol, the impact on the lining 12, retracts the crank 4 with the tong clamp on the guide 1 up to the stop 14 and the cheeks 9 and W under the action of the spring 8, clamping the transverse rod. The rod, clamped at one end by the cheeks 9 and 10 of the tong tong, is moved to the bunker when moving to the welding zone 16 with another ring.

At the end of the thrust stroke, the // rod of the rod comes off the stop, the tongue grip by the lever 6 hits 13, the cheeks diverge, and the rod enters the welding zone on the longitudinal rods.

I

When the thrust 11 moves, in the opposite direction, the cage 4 with the clamp MOVE | M returns to its original position. The cycle is repeated.

Subject invention

The mechanism of supplying transverse rods from the bunker to the electrodes of the machine for welding reinforcing mesh of reinforced concrete products, contains a driving feed carriage mounted on the machine frame with a tong-pinched transverse rod, characterized in frame. in the area of the bunker and welding electrodes, stops are installed that act on the corresponding levers of the tong and seizure, under the ruler relative to each other, when it is reciprocated upatelnom movement and ensure capture of the hopper bar and release it under ele.ktroda.1i machines for welding.
