[0023]
Next, as shown in FIG. 3B, the upper die is lowered to lower the piece cutting punch 2 and the presser plate 10, and the member 1 raises the eject pin 3 by compressing the spring 16 to raise the presser plate. 10 is sandwiched between the die plate 9 and the piece cutting die 5 and the tip of the pilot pin 4 is inserted into the guide hole 1a of the member 1, and the piece cutting punch 2 and the presser plate 10 are lowered. As shown in FIG. 3C, the presser plate 10 is stopped at a position in close contact with the upper surface of the member 1, and only the piece cutting punch 2 is lowered to a predetermined lower surface position, and the pilot pin 4 is moved to the guide hole 1a. To position the member 1.
[0024]
Next, as shown in FIG. 3D, the piece cutting punch 2 is further lowered to cut the hoop-shaped member 1 into pieces 21a by the piece cutting punch 2 and the piece cutting die 5. The tip of the pilot pin 7a is inserted into the guide hole 1b of the piece 21a from below, and the piece 21a is positioned on the upper surface of the receiving block 22a coupled to the slider 6a.
[0025]
Next, as shown in FIG. 3E, when the piece cutting punch 2 is raised, the eject pin 3 releases the piece 21a from the lower surface of the piece cutting punch 2 by the compression release force of the spring 16, and the slider 6a. Is held at a position regulated by the pilot pin 7a of the receiving block 22a coupled to the upper surface of the plate, and then, as shown in FIG. 3 (f), the piece cutting punch 2 and the presser plate 10 are further raised to return to the original position. By returning to the position, the cutting process in the processing part is completed.
[0026]
The piece 21 to be cut by the receiving block 22 coupled to the slider 6 is obtained by cutting the same or different hoop-shaped member 1 by the same operation simultaneously with the processing at the processing portion. Because of this, the description is omitted.
[0027]
Next, the slider 6 which is inside the sliders 6 and 6a to which the receiving blocks 22 and 22a for positioning and holding the pieces 21 and 21a simultaneously cut and processed by the processing portion are combined is shown in FIG. By moving only by a variable mechanism (not shown) to the state shown in FIG. 4, the interval between the piece 21 and the piece 21a is set to an interval required by the next process (not shown).
[0028]
Next, when the slider 6 is continuously moved in the direction of the arrow in FIG. 4, the stop surface 27 of the slider 6 moves together while closely contacting the stop surface 25 of the slider 6a, and is fixed to the die plate 9 as shown in FIG. The stop surface 26 of the slider 6a comes into contact with the stopper 19a and stops. The dimensions required for performing various processes such as chucking, marking, drilling and caulking in the next process (not shown), that is, the dimension B The individual pieces 21 and 21a with an extended distance are conveyed and supplied to a processing position (not shown) in the next process, and the operation for one process is completed.
[0029]
As described above, when the parts processing apparatus having the transport mechanism according to the present invention processes a plurality of members simultaneously and sends them to the next process, the interval between the individual pieces in each process is determined depending on the type of process, operation, and jig. When a change such as expansion of the interval is required for a metal mold or a mechanism, a plurality of pieces can be transported and supplied simultaneously with a simple configuration.
[0030]
In this embodiment, an example of cutting a hoop-shaped member and conveying a cut piece has been described. However, the member is not a hoop shape, but a member such as a sheet or strip having a fixed size, It goes without saying that not only cutting processing but also various processing such as bending, caulking, pressing, drilling, and attachment of other members may be used.
[0031]
【The invention's effect】
As described above, according to the present invention, a plurality of workpieces can be simultaneously conveyed and supplied at intervals necessary for separate processes without requiring a material supply mechanism as a separate device. It is also possible to convey and supply while arbitrarily setting the dimension B between products, which has the effect of improving productivity and reducing the cost of equipment.
