BACKGROUND OF THE INVENTION
The present invention relates to a wire straightening supply device for supplying a wire to a forging machine that forges bolts, nuts, or other parts, and belongs to the field of metal part manufacturing technology.
[0002]
[Prior art]
Conventionally, as disclosed in, for example, Japanese Patent Publication No. 7-11975, etc., a material made of metal or the like cut into a predetermined size is sequentially supplied to a plurality of forging stations, whereby the material is gradually specified. Forging machines that are finished in shape products have been put into practical use.
[0003]
In this case, this type of forging machine is generally provided with a wire straightening supply device for supplying the wire to the forming machine. In this wire straightening supply device, a support rod for hanging the wire that protrudes horizontally from the main body of the device, a feeding roller for feeding the wire to the molding machine, or straightening the wire when feeding the wire A straightening roller is provided.
[0004]
On the other hand, the wire set in the wire straightening / supplying device is wound in a coil shape and is bound by a binding member at a plurality of surrounding locations so as not to diffuse.
[0005]
When setting the wire rod to the wire straightening and feeding device, the coiled wire rod as described above is suspended from the support shaft using a crane or the like to cut the binding member, and then the end portion of the wire rod is searched. The terminal portion is held between the rollers of the supply device and fed out to the molding machine side while being straightened. Further, the wire rod fed out as described above is sandwiched between the take-in rollers that take in the molding machine, whereby the wire rod can be supplied to the molding machine.
[0006]
[Problems to be solved by the invention]
By the way, it may be necessary to change to another wire having a different diameter or material before it is completely used due to a change in a product to be manufactured by a forging machine.
[0007]
At that time, the wire rod is cut in the middle to remove the linear wire rod held between the rollers of the molding machine, and the wire rod remaining on the support shaft is gathered together from the diffused state in the axial direction of the support shaft. Then, after binding again with the binding member and removing it from the support shaft using a crane or the like, the wire to be replaced next is suspended on the support shaft, and the above-described supply preparation work is performed. Replacement work and supply preparation work are large work and take time. In particular, it takes time to adjust the straightened state of the wire according to the diameter of the wire, and the operation of the forging machine needs to be interrupted while such work is being performed.
[0008]
In that case, in the conventional wire straightening supply device, since only one support shaft is provided to support the wire, the wire to be replaced next is removed until the wire remaining on the support shaft is removed from the support shaft. It was not possible to set, and the operation interruption time of the forging molding machine became long, and the working efficiency of the molding machine was greatly reduced.
[0009]
Therefore, the present invention has an object to improve the working efficiency of the forging machine by shortening as much as possible the interruption time of operation of the forging machine that occurs at the time of wire rod replacement work in the wire straightening and supplying apparatus. And

[0039]
Then, in the other wire straightening supply mechanism 10 ', as described above, it is fed forward through the straightening rollers 20' to 22 'and supplied to the forging forming machine 2 to operate the forming machine 2 and send it out. When the roller 16 is fed out by the motor 17, the wire Y is successively fed out by the feed rollers 2a ... 2a on the forging machine side and continuously supplied to the forging machine 2.
[0040]
Meanwhile, in the meantime, the wire X remaining on the support shaft 15 of the one wire supply mechanism 10 is removed from the support shaft 15 using a crane or the like, and another wire is suspended and set on the support shaft 15. Become.
[0041]
In this way, when the wire is replaced, it can be replaced with the next wire Y without waiting for the completion of the operation of removing the wire X remaining from the support shaft 15, so that the next wire Y is supplied promptly. As a result, the time during which the operation of the forging machine 2 is interrupted is shortened, and the working efficiency of the forging machine 2 can be significantly improved as compared with the prior art.
[0042]
In addition, a coiling roller 23 for bending the straight wire X again into a circular shape is provided, and the coil diameter when the straight wire is bent again by changing the wire holding position of the coiling roller 23 is changed. In the past, a wire made of metal or the like was bent from a straight straightened state into an arc of the coil diameter of the wire remaining on the support shaft. Work that took time can be performed relatively easily and quickly.
[0043]
【The invention's effect】
First, according to the wire straightening supply device of the first invention, since one support shaft is used and the other support shaft is vacant as a spare support shaft, when the wire to be replaced next is known, While one spindle is being used, the next wire can be set in advance on another spindle. Further, even when the next wire is known at the time of replacement, the next wire can be set on the other shaft by overlapping in time with the operation of removing the wire from the one shaft.
[0044]
Therefore, if it is necessary to replace the wire with a different diameter or material before it is completely used up due to a change in the product to be manufactured by the molding machine, conventionally, the wire is removed from the support shaft using a crane or the like. Although the said other wire was not able to be supplied, the following wire is replaced | exchanged rapidly by setting it as the above structures. As a result, the time for interrupting the operation of the molding machine is shortened, and the working efficiency of the molding machine can be greatly improved as compared with the conventional art.
[0045]
In addition, for example, in the case of a supply device provided with two support shafts, it is almost the same as the conventional supply device for two units provided in the space of one supply device, and high efficiency of the space is realized. Will be.
[0046]
Next, according to the wire straightening / supplying device of the second invention, it is very difficult to bend a wire made of metal or the like into a circular arc of the coil diameter of the wire remaining on the spindle from a straight straightened state. However, when the wire was rewound, a bending roller member was provided to bend the wire into the arc of the coil diameter of the wire remaining on the support shaft.
