Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bar material fixed position stopping device for receiving and carrying out bar materials successively sent from a bar material processing machine main body.

<Prior Art> In a conventional bar processing machine, a metal material is processed into a bar, cut into a desired length, and then straightened or grinder finished to obtain a bar. Particularly, in a continuous drawing machine of a bar processing machine, a round bar is straightened and polished and sent as a bar to a wire pedestal.

And the bar material 1 sent out one after another from the bar material processing machine main body
As shown in FIG. 5, the bar is clamped at a fixed position by the bar retainer 3 provided on the wire receiving base 2 so as to be lifted and stopped. Then, the bar 1 is released by the rise of the bar presser 3, rolls down the inclined wire receiving plate 4, is put into the pallet 5 and is bound and taken out.

<Problems to be Solved by the Invention> However, in the above-described conventional technique, it takes a little time for the bar material 1 to start rolling after it has stopped moving, and the bar materials 1 are successively fed from the bar material processing machine main body. , The bar that comes from behind catches on the bar that is rolling down,
There is a danger that the bar will get caught on the wire pedestal, and if it is bent, problems will occur when the bar is bent, and it will not be possible to drop it in a certain place.

In view of the above, the present invention is a bar material for a bar processing machine that can move the bar materials sequentially sent from the bar material processing machine main body on the wire pedestal and move the bar materials at the same time to accumulate them at a fixed position. The purpose is to provide a fixed position stop device.

<Means for Solving Problems> The problem solving means according to the present invention is, as shown in FIGS. 1 and 2, a wire receiving base 11 for receiving the bar 1 continuously fed from the bar processing machine body 10. In the bar processing machine having the above, the wire pedestal 11 includes a bar pressing member 12 for stopping the fed bar 1 at a fixed position, and the pressing member 13 for shifting the stopped bar 1 from its traveling direction is the bar. Interlocking means 14 is provided which operates in conjunction with the presser motion of the presser foot 12.

<Operation> In the above problem solving means, when the bar material 1 is sent from the bar material processing machine body 10 to the wire pedestal 11, an operation signal is output to the bar material fixed position stopping device. By this signal, the bar pressing member 12 is operated to lower the bar pressing member 12, and the pressing member 13 is rotated in the direction of the bar pressing member 12 by the interlocking means 14 accordingly.

Then, during the stroke before the bar retainer 12 continues to press the bar 1, the bar 13 comes into contact with the bar 1 and the bar 1 is slightly displaced from the traveling direction and immediately descends. The bar 1 is pressed by the presser 12 and stops at a position displaced from the traveling direction.

Therefore, since the stop position of the previous bar 1 is deviated from the advancing direction of the next bar 1 with respect to the bar 1 sequentially sent from the bar processing machine main body, The next bar 1 can be prevented from being caught, and the bar 1 can be efficiently conveyed one after another. Moreover, since the bar pressing member 12 and the pressing member 13 can be operated in an interlocking manner with a simple structure, the cost of the bar member fixed position stopping device can be reduced.

The continuous drawing machine main body 10 is, as shown in FIG. 3, a wire drawing device 15 for cold drawing the coiled metallic material A.
A straightening device 16 for straightening the drawn material, a cutting device 17 for cutting to a desired length, and a straightening and polishing device 18 for polishing the cut material. In the figure, 19 is a driving part such as a motor, and 20 is an intermediate guide. Further, a detection switch 21 such as a photo interrupter for detecting the rear end of the bar 1 sent to the wire receiving base 11 is arranged on the exit side of the polishing device 18.

As shown in FIG. 1, the wire receiving base 11 includes a wire receiving plate 22 for receiving the bar 1 and a bar member fixed position stopping device main body 23 arranged on the wire receiving plate 22. The receiving plate 22 is provided so as to be inclined at about 5 degrees in a direction orthogonal to the traveling direction of the rod 1, and a portion made in contact with the rod 1 is made of synthetic resin for preventing damage to the rod 1. The material 24a is fitted.

The bar retainer 12 includes a retainer plate 26 that is supported on the main body 23 of the apparatus via a pair of left and right slide bearings 25 so as to be able to move up and down.
To raise and lower the holding plate 26, the holding plate 26 is bolted 27.
And a pneumatic cylinder 28 taken from Further, the bolt 27 enables height adjustment between the pressing plate 26 and the wire receiving plate 22.

The holding plate 26 is formed in a rectangular shape in a side view, and a protective member 24b made of synthetic resin is attached to the contact surface with the lower bar member 1.

The pressing member 13 is a substantially rectangular flat plate and is arranged at both ends of the bar pressing member 12, and the upper portion thereof is rotatably supported by the device main body 23 by a pin 29. An extruding plate 3 for extruding the rod 1 in the direction of inclination of the wire receiving plate 22 is provided below the pushing member 13.
0 is attached, and a protective material 24c is attached to the surface thereof. A recess 31 for housing the push-out plate 30 is formed on the side wall 23a of the apparatus body 23.

The interlocking means 14 is provided with a guide groove 3 which is recessed in the pressing member 13.
2 and a rolling element 33 attached to the holding plate 26. The guide groove 32 is formed in a dogleg shape at the center of the inner surface of the left and right pushing members 13, and the rolling elements 33 are attached so as to project outward from both ends of the holding plate 26.
Then, the rolling element 33 engages with the guide groove 32 so that the rod retainer 1
By the raising and lowering of 2, the rolling element 33 slides in the guide groove 32 in the vertical direction, and the pressing member 13 is rotated in the direction orthogonal to the traveling direction of the rod 1. Further, a spring 34 is attached to the rear surface of the pressing member 13 for urging the pressing member 13 in a direction of moving the pressing member 13 away from the pressing plate 26 when the pressing plate 26 is lifted.

Since the bar 1 is sent out from the straightening / polishing device 18 at high speed, the bar fixed position stopping device detects the rear end of the bar 1 by the detection switch 21 and at the same time operates the pneumatic cylinder 28 to operate the bar 1. It is controlled to lower the material presser 12.

In the above structure, the coiled material A is linearly cold drawn through the wire drawing device 15, straightened by the straightening device 16, and then cut into a desired length by the cutting device 17 to obtain a bar material. After the round bar is cut, the outer peripheral surface is polished again by the straightening / polishing device 18, and in the case of a deformed material, it passes through the straightening / polishing device 18 and is sent from the straightening / polishing device 18 to the wire receiving base 11 at high speed. .

When the bar 1 comes out of the straightening / polishing device 18,
The detection switch 21 detects the rear end of the bar 1 and outputs an operation signal to the bar fixed position stop device. This signal causes the pneumatic cylinder 28 to extend and lower the holding plate 26. As the pressing plate 26 descends, the rolling elements 33 slide downward in the guide grooves 32 of the pressing member 13 as shown in FIG. 4 (a), and the pressing member 13 moves in the direction of the bar pressing member 12. Is rotated to.

Then, as shown in FIG. 4 (b), the pushing member 13 comes into contact with the rod 1 sliding on the wire receiving plate 22, and the rod 1 is slightly pushed out from the traveling direction in the inclination direction of the wire receiving plate 22. Fig. 4 (c)
As described above, the bar 1 is immediately pressed down to the wire receiving plate 22 by the pressing plate 26 and stopped at a position displaced from the traveling direction.

Then, when the pneumatic cylinder 28 is shortened and the holding plate 26 rises, the bar 1 is released from the holding plate 26 and the wire receiving plate 2
It is received by the rolling pallet along the inclination of 2, and is collected and taken out.

Further, as the pressing plate 26 rises, the rolling element 33 slides upward in the guide groove 32 of the pressing member 13 and the urging force of the spring 34 causes the pressing member 13 to move to the side wall 23 a of the apparatus main body 23. The push plate 30 is rotated, the push plate 30 is stored in the recess 31 of the side wall 23a, and the fixed position stopping operation of the bar 1 is completed. At the same time when this operation is completed, the straightening and polishing device 18 for the next bar 1 is sent out, and the series of operations as described above are successively performed.

Therefore, since the stop position of the previous bar 1 is deviated from the advancing direction of the next bar 1 with respect to the bar 1 sequentially fed from the continuous drawing machine main body, It is possible to prevent the bar 1 from being caught and to efficiently drop the bar 1 on the stacking table. Moreover, since the bar pressing member 12 and the pressing member 13 can be operated in an interlocking manner with a simple structure, the cost of the bar member fixed position stopping device can be reduced.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

In the present invention, an example of the continuous drawing machine is given, but it can be used as a wire pedestal in all bar processing machines.

Further, a link mechanism or a cam mechanism may be used as the interlocking means to interlock the bar pressing member and the pressing member.

<Effect of the Invention> As is clear from the above description, according to the present invention, the wire pedestal that receives the rods continuously fed from the main body of the rod processing machine presses the fed rods at a fixed position. A bar member provided with a bar pressing member is provided which is interlocked with the pressing member for displacing the stopped bar member from its advancing direction in synchronism with the pressing operation of the bar pressing member, and is successively fed from the bar processing machine body. On the other hand, since the stop position of the previous bar is displaced from the moving direction of the next bar, it is possible to prevent the next bar from being caught on the previous bar, and the bar can be efficiently removed one after another. Can be transported. Moreover, since the bar pressing member and the pressing member can be operated in an interlocking manner with a simple structure, it is advantageous when the cost of the bar fixed position stopping device can be reduced.
