The operation of the forging forming method using the raw material supplying apparatus of the present invention will now be described.

As is known, the raw material enters the workpiece forming process (S180) and the forging machine, and the bending process is performed in a straight line. Subsequently, at the same time as the cutting process for forming the workpiece, The raw material supply device 100 for supplying the raw material, which is a feature of the present invention, to the forging molding machine 1 is described in detail, Will be described in detail.

Specifically, the raw material supply device of the forging molding machine according to an embodiment of the present invention sequentially supplies the raw material P held on the first conveyor B1 to the forging molding machine side.

At this time, as shown in Fig. 1, the raw material is supplied in such a state that the end portion of the end is directed to the right of the first conveyor B1.

The first conveyor (B1) is separately driven, and the conveying operation is performed through the controller (80).

The lower side fork member 30 of the second cylinder C2 positioned on the upper side of the support main body 10 constituting the raw material supply device 100 in a state where the raw material is positioned at the end position of the first conveyor B1, The fork foot constituting the fork member is inserted into the bobbin P1 of the raw material.

The fork feet are arranged in a plurality of circumferential directions and are inclined at one side so as to accommodate the inner diameter of the bobbin P1 so that insertion of the bobbin is easy. When the fork feet are inserted into the bobbin, To the center of the turntable (40) on the part (13).

The upper second cylinder C2 of the fork member 30 is provided on the slider 20 and is connected to each of the first cylinder C1 side working rods provided outside the guide portion 11 And is moved along the lengthwise elongated hole 11a of the guide portion 11 by the operation rod advancing operation of the first cylinder C1.

Here, the second cylinder C2 is moved in a section in which the first sensor and the second sensor C2 are located in the horizontal section 12 on the upper side of the horizontal frame 10B, The second cylinder C2 and the fork member 30 are precisely positioned at the upper center of the turntable 40 in accordance with the position so as to set the raw material.

The above operation corresponds to the raw material transferring step S120 in the present invention. In the raw material turning step S130, the raw material P is operated by the driving motor M1 placed on the turntable 40, Together with the turntable 30, rotates the raw material P in the counterclockwise direction on the drawing basis. At this time, the fork foot of the fork member 30 is simultaneously rotated with the rotation of the upper side rotary body 22 under the influence of the rotation of the turntable 40 while being inserted into the bobbin P1 of the raw material P, (C2) remains stationary.

The rotation of the first driving motor M1 is performed at a low speed at which the raw material P can be slowly released without being rotated at a high speed. The rotation of the first driving motor M1 is controlled by the operation of the guide member 60 provided on the receiving portion 13 Thereby leading the end terminated from the raw material to the outward direction of the raw material. This process corresponds to the raw material end drawing process (S140).

7, the guide member 60 rotates the pneumatic cylinder 63 from the rotary shaft 62 so that the tip of the inclined body 61 can be closely contacted with the outer periphery of the raw material in an inclined manner .

At this time, And at the same time, it is naturally induced along the inclined lateral part of the inclined body as shown in Fig. 8 (a) and gradually spreads outward.

As the end of the raw material P spreads as described above, the end of the raw material P is guided between the driving roller Rl and the idle roller R2 corresponding to the raw material straightening step S150 so that the raw material is linearly spread, , The feed is performed in the straight direction in which the forging molding machine 1 is located.

The rotation of the driving rollers R1 is performed through a second driving motor M2 provided on the lower side of the receiving unit 13 and a power transmission medium connected to the second driving motor M2, It can be spread out in a straight line.

The raw material having passed through the idler roller R2 is processed into a semi-spherical shape by the abrasive section 70, and after the attachment is removed, the raw material is supplied into the forging molding machine. Such a process corresponds to a step S160 of polishing a raw material end.

The weight of the raw material P is measured. When the weight of the raw material P is lowered and the measured value is only the weight of the bobbin, the controller 80 controls the rotation of the turntable, To move the fork member 30 away from the bobbin P1, as shown in Figures 9 and 10 attached hereto. This process corresponds to the bobbin discharging process (S170).

When the fork member 30 is lifted up as described above, the third cylinder C3 positioned on the receiving portion 13 operates the operating rod to advance the end side pushing rod so as to move the bobbin P1 to the turntable 40, The bobbin pushed out of the material feeding device 100 can be pushed out to the upper surface of the second conveyor B2 located between the bobbin guides 13b on the receiving surface.

After the bobbin P1 is discharged as described above, when the operating rod of the third cylinder C3 is returned to the initial state by moving back the plunger 50, the second cylinder C2 is moved to the first position The raw material P waiting on the upper part of the conveyor B1 is moved to the turntable 40 side of the raw material supply device 100 and the raw material for the forging can be supplied to the forging molding machine 1 while rotating the raw material.
