SU628267A1 - Device for making two-loop bundles from reinforcing wire - Google Patents

Description

The invention relates to devices for the manufacture of reinforcing wire bundles used in the manufacture of prestressed concrete structures,

A device for manufacturing two-loop bundles of reinforcing wire is known, comprising a spreader bar, end blocks on which reinforcement wires are packed, and clamping inserts.

A disadvantage of this device is the need to use an additional device for winding the wire onto the end pads,

Another device of the same purpose is known, comprising a horizontal wheel with adjustable templates, a drive for its rotation, a drum connected to the shaft and the coupling, connected to the sector rotary mechanism of the drum, and guide rollers of the wire feeder 2.

A disadvantage of this device is its complexity due to the large

the number of ki) of workers and transmission elements and devices that are chemically connected to themselves, which are not connected to 1 with several driving mechanisms.

Closest to the invention, there is a device for producing two-petroleum beams of reinforcing wire comprising a drum mounted on a vertical shaft with a device for securing the ends of the beam, a rotation drive of the drum, and a wire stacker r3j. The disadvantages of this device are} (COOP in applying manual labor in the process of packing the wire) ia drum and its design due to the presence of transmission from the drum shaft to the wire stacker.

The purpose of the invention is to automate the process of laying the wire on a barzaban and to simplify the design of the device,

In the proposed device for the manufacture of 1n double-welded bundles of reinforcing wire, which is mounted on a vertical shaft with a fixture for fixing) the 1H end of the 6 Hz beam, the rotation drive bprpana and the wire stacker are made in the form of a carriage mounted on a rack, on which is pivotally fixed a guide tube with the following roller, which interacts with the guide and directs the next chute, forming the drum onto the drum Fig. 1 schematically shows the described device, a general view; in fig. 2 is a section according to A-A in FIG. 1. The device comprises a drum 1 mounted on a vertical shaft, having a reversible drive of rotation from an electric motor 2 through a reducer 3. On the surface of the drum there is a helical guide chute formed by ribs 4, n fixture for fixing the ends in the form of pegs 5 and 6, the Wire Layer is made in the form of a guide tube 7, mounted together with the following cable 8 with the aid of 1 of the head 9 on the carriage 10, which is installed with the possibility of free transmision on the vertical stand 11, one On the surface of the drum 1, near each peg 5 and 6, switches 12 are installed, interacting with the wire stacker and changing the direction of rotation of the drum 1. The device operates as follows. The reinforcing wire 13 is passed through the guide tube 7 and is fixed on the collar 6 of the drum 1. Then the drum 1 is turned in a clockwise direction (when looking at the drum 1 from above). In this case, the reinforcement wire 13 will be wound on the drum 1 into the chute along a helical line, described with respect to the drum 1 by the stacker tube 7 under the action of the follower roller 8 which rolls along the lower edge 4 of the guide. The carriage 10 and the post 11 provide free movement of the tube 7 in the direction of the forming surface of the bar 1 of the bar. When the reinforcement wire 13 is laid to the upper end of the groove, the 74 roller 8 along the edge 4 will go around the coco 5, making a turn around the joint along with the 7 9 with a simultaneous lifting of the carriage 10 upright 11. The switch 12 is activated and the direction of rotation of the drum 1 is changed. The follower roller 8 moves to the upper edge 4 of the guide groove, ensures that the wire is laid to the lower spike 6 and leads around the wok HS is not the first reinforcement wire, the switch to the lower edge 4 of the guide chute. Then the process is repeated automatically until the required wire bundle is obtained. The transition of the follower roller 8 from one chute edge to the other in extreme positions is due to the tension of the reinforcement wire iSj, which tends to unfold the follower to 8 around the joint 9 due to the asymmetrical position of the tube 7 relative to the forceful. The finished beam is removed from the device. Formula of the Invention A device for the manufacture of two-loop beams of reinforcing wire containing a drum mounted on a vertical shaft with a device for fixing the ends of the beam, a rotation drive of the drum and a wire stacker, characterized in that, to automate the laying process the wire on the drum and simplify the design of the device, the wire stacker is made in the form of a carriage mounted on the rack, on which the guide tube with the following role is pivotally fixed com interacting with the screw guide chute formed on the drum Sources of information taken into account during the examination: 1.
