Further, a draw-out guide roller provided on at least one of the support blocks for guiding the longitudinal movement of the rod-like material may be further provided to facilitate the drawing of the rod-like material.

The aligning roller has an aligning position in which the stick-shaped material to be supplied to the supporting block waits, the aligning roller supporting the stick-shaped material movably in the longitudinal direction at the aligning position, And an alignment stop which is in contact with the heated end of the rod-like material moved by the aligning roller, helps to keep the heating position of the rod-like material constant.

Here, the standby position before alignment and the standby position after alignment are provided before and after the alignment position, respectively, thereby contributing to the prevention of errors and the operational stability of the apparatus.

On the other hand, the conveying portion includes a pitch conveying member, such as an elevation and a horizontal movement, having a plurality of placement grooves having pitch intervals such that the bar-like materials existing at the respective standby positions and the alignment positions are placed, And a feed drive unit for feeding the pitch one pitch along the feed direction and then lowering it.

The apparatus for heating and supplying the rod material for forging according to the present invention has an effect of improving the efficiency in forging the rod material because the rod material is optimally conveyed, aligned, and heated.

In addition, since a large amount of rod-shaped material is fed and heated one by one from the loaded part, it is effective to increase work safety and work efficiency.

[ A heating section 60 having a high frequency induction coil 61 is provided on the same position as the heating and charging section 50. At this time, the position of the high frequency induction coil 61 is provided at a position where the rod-like material placed on the heating charging part 50 can be inserted.

On the other hand, a feed driving section 40 for sequentially moving the rod-like material of the first air bearing section 34a to the heating and charging section 50 is provided below the frame 10 composed of the two layers.

On the other hand, the transfer plate 47 has a cutout portion for preventing contact with the three alignment rollers 36. [

According to the structure as described above, the rod-like material is high-frequency induction-heated and supplied to the user in accordance with the operation procedure shown in FIG. 2 to FIG.

2 is a view showing a state immediately before the stick-shaped material placed on the heating loading portion 50 is inserted into the high-frequency induction coil 61 of the heating portion 60. Fig. As can be seen from Fig. 2, the rod-shaped material placed on the heating loading part 50 is fixed by the clamp 59. [ 3, the charging slider 55 of the heating charging part 50 moves along the charging rail 57, and one end of the stick-shaped material is inserted into the high frequency induction coil 61. [

At this time, the control unit causes the charging slider 55 to move backward after heating the rod-shaped material placed on the heating charging unit 50 for a predetermined time and temperature, and releases the clamp 59 after moving backward. Then, as shown in Fig. 4, the heated stick-shaped material is supplied to the user and disappeared. At this time, the draw-out guide roller 53 makes it easy for the user to pull out the stick-shaped material on the heating loading portion 50 in the longitudinal direction.

When the rod-shaped material of the heating charging part 50 is supplied to the user, the charging sensor 52 transmits a signal indicating the non-sticking material on the heating charging part 50 to the control part. When the control unit receives the rod-shaped material absence signal, the control unit drives the feed drive unit 40 as shown in FIGS.

5 shows that the rod-like material lying in the first waiting portion 34a, the second waiting portion 34b, the third waiting portion 34c, the aligning roller 36 and the fourth waiting block 39 is located at the bottom Is just before being raised by the back pitch conveying member 49. Fig. At this time, the distance L between the stick-shaped materials and the spacing L between the mounting grooves 48 of the equal-pitch conveying member 49 are the same.

When the equal pitch conveying member 49 is ready to be elevated as shown in Fig. 5, the equal-pitch conveying member 49 rises while the conveying cylinder 45 is driven as shown in Fig. At this time, the first waiting portion 34a, the second waiting portion 34b, the third waiting portion 34c, the aligning roller 36, and the fourth waiting block 34c are formed in the mounting groove 48 of the equal pitch conveying member 49, The rod-like materials placed on the rod 39 are put together and raised.

Then, the feed slider 43 moves on the feed rail 41 as shown in Fig. The moving distance of the feed slider 43 is equal to the distance L between the mounting grooves 48 of the equal pitch conveying member 49. On the other hand, when the feed slider 43 moves horizontally, it is preferable that a pulling string (not shown) is provided on the feed plate 47 so as to pull the rod-like materials waiting on the first air bearing portion 34a.

8, the equal pitch conveying member 49 is lowered by the driving of the conveying cylinder 45, and the stick-shaped materials on the five placement grooves 48 of the equal pitch conveying member 49 The aligning roller 36, the fourth waiting block 39, and the heat charging part 50. The first and second waiting blocks 34a, 34b, 34c,

As shown in FIG. 9, the rod-like material at the alignment position is brought into contact with the alignment stop 37 by the rotation of the aligning roller 36 so that the heated end of the rod-like material comes into contact with the alignment stop 37. Further, the rod-like material on the heating loading portion 50 is fixed by the clamp 59. The operation process of the heat charging part 50 to be performed later is the same as the process from FIG.

10, when there is no rod-like material on the end portion of the first air-bearing portion 34a in the supply direction, the first sensor 35 senses that there is no rod-shaped material and transmits a rod-shaped materialless signal to the controller. The control unit, which has received the rod-shaped material-free signal on the first base portion 34a, rotates the rotary plate 31. When the first sensing sensor 35 senses that there is a rod-shaped material on the first air bearing portion 34a, the first sensing sensor 35 transmits a rod-shaped material containing signal to the first air bearing portion 34a to the control portion And the control unit stops the rotation of the rotary plate 31. [

The apparatus according to the present invention can adjust the inclination of the support table 21 by rotating the support rod 23 by driving the first cylinder 27. [ On the other hand, the first cylinder 27 may be provided on the bottom surface of the frame 10 to raise and lower the support rod 23.

The number of the rotary plate pins 31a of the rotary plate 31 is preferably two but is not limited thereto.

The apparatus according to the present invention may not have the second waiting portion 34b, the third waiting portion 34c and the fourth waiting portion. At this time, the equal pitch conveying member 49 has only the first standby portion 34a and the three placement slots 48 corresponding to the alignment position.

Meanwhile, the charging sensor 52 according to the present invention may be provided in the clamp 59.

In addition, the heating charging section may not have the drawing-out guide roller.
