DD286789A5 - CLAMPING DEVICE FOR BINDING WIRE - Google Patents

Abstract

The invention relates to a tensioning device for binding wire, which is used on wire binding machines, which serve for binding sharp-edged packages of mold steel, for tightening the binding wire. Such wire binding machines are used in rolling mills. It is the object of the invention to reduce the equipment costs for such wire binding machines, to reduce the time required for binding and to achieve a secure, in particular tight binding. The inventive clamping device is characterized by a fixed to a preloaded lever role. The role over which the binding wire is pulled taut, releases the wire completely only when the tension canceling the preload is reached and thus a tight, tight-fitting wire bond is achieved.

Description

Tying head 9 attached. From the channel 10 of the guide 11, which is closed during the bypassing of the binding wire 12 by the mounted on the movable upper bypass 13 plate 14, the binding wire 12 is pulled out before the reversal of the driver 15 by claws 13. It will then practice both when reversing. the binding material 17 as well pulled over the roller 4. In this case, the roller 4 partially encompassing deflector 18 prevents passing of the binding wire 12 on the roller 4. With sufficiently large tensile force, which can be regulated by the adjustable bias of the compression spring 7, the lever pivots 1 and thus reaches the roller 4 an inclined position , so that the binding wire 12 slips laterally from the roller 4 and is pulled completely by the driver 15 to the binding material 17. ' After slipping the binding wire 12 of the lever 1 jumps through the prestressed compression spring 7 in its initial position against the stop 19 back.

1. clamping device for binding wire to a wire binding machine for tightening the binding wire stack of sharp-edged forming steels, wherein the binding wire is guided in a guide within the bypass of the wire binding machine, characterized in that a roller (4) rotatably on a means of compression spring (7) and spring plate (6) prestressed pivotable lever (1), which is supported on the bypass (2) of the wire binding machine, is mounted. 2. Clamping device according to claim 1, characterized in that a roller (4) in the Bin'dedrahtlaufbereich partially encompassing deflector (18) is rigidly arranged on the bypass (2). For this 2 pages drawings Field of application of the invention The invention relates to a tensioning device for binding wire which is used on wire binding machines, which serve for binding sharp-edged packages of mold steel, for tightening the binding wire. Such wire binding machines are used in rolling mills. Characteristics of the known prior art When strapping sharp-edged packages made of shaped steel with binding wire by means of the usual Drahtbindemaschinan, it is impossible, especially in wires with large cross-sections, to achieve a sufficiently tight and thus firm binding by pulling on one side of the wire. Even with bilateral tightening the wire ends the required tightness can not be guaranteed. To avoid this deficiency, solutions have been created in which the diversion consists of several separately operable segments, each releasing the wire one after the other. Furthermore, it is known to arrange additional roles within the bypass, over which the wire is stretched and release the wire, after a partial wrapping of the package was created by hydraulically triggered pivoting to complete the binding. Through the use of hydraulic actuation and control such binding machines are very expensive and the required swivel times increase the time required within the technological flow. Object of the invention It is the object of the invention to reduce the equipment costs for binding machines and to reduce the time required for binding sharp-edged packages made of shaped steel. A tight, tight-fitting binding should ensure a safe handling of the bound packages. Explanation of the essence of the invention It is the object of the invention to provide a tensioning device for binding wire to wire binding machines, which also gaiantiert when binding sharp-edged packages of Pormstahl on all sides of the stack an ens fitting and thus taut binding. According to the invention, the problem is solved in that a roller is rotatably mounted within the bypass of the wire binding machine, that the wire initially rests on this role after leaving the guide. In this case, the role is mackerel on a lever which is held by means of a preloaded spring and a spring plate with a defined force until the tensile force acting through the reversing operation on the current over the roller binding wire, is so large that they pivot of the lifting and thus leads to slipping of the binding wire from the roll. By a role in the binding wire running area partially embracing deflector, which is rigidly mounted on the bypass, premature slipping of the wire is prevented by the role. Execution tbeispiel
