工に困難を来たしていた。 Generally, when pressing parts of electronic devices, such as pole pieces that are parts of magnetrons,
Pressing is performed using a progressive die layout in which multiple workpieces are arranged and combined along the feeding direction using carriers. By the way, the above-mentioned pole piece has a thick-walled conical shape, and it is necessary to make a hole in the side surface, that is, the tapered surface. In the conventional progressive carrier, as shown in Fig. 1, a workpiece 11 and a carrier 12 are formed by hour glass punching, and the machined surface of the workpiece 11 is punched in the conical direction. It forms almost a right angle. However, when drilling a conical tapered surface, the processed surface becomes an inclined surface with respect to the processing direction of a normal punch. For this reason, machining has been carried out using a cam mechanism or the like, but the structure has become complicated and, however, a large extraction force cannot be obtained, making machining difficult.

によるプレス加工方法を提供することにある。 An object of the present invention is to use a progressive carrier that can bend the joint between the workpiece and the carrier in the middle of the process, and to keep the punch vertical even when machining a tapered surface by bending the joint. To provide a press working method using a progressive carrier, which enables stable working with a large punching force by positioning the working surface at a substantially right angle.

This is a press working method using a progressive die layout, which is characterized in that the connecting member of the progressive die layout is bent to position the processing surface of the workpiece approximately at right angles to the punch.

とからなるクランプ状のものである。 The details of the present invention will be explained below with reference to an embodiment shown in the drawings. FIG. 2 shows a progressive die layout used in the present invention. In the figure, 15 is a pair of carrier members parallel to each other, and a plurality of workpieces 16 are arranged between the carrier members 15 along the longitudinal direction. Arranged. These works 16 are connected to a pair of carrier members 1 via connecting members 18, respectively.
5 are integrally connected. The connecting member 18
is a bendable bending portion 1 along the carrier member 15.

し、従来より安定した送りが可能になつた。 FIG. 4 shows a case in which a pole piece, which is a magnetron component, as described above, that is, a thick-walled conical part having a hole in the tapered surface, is processed using the above-described progressive die layout. Here, the feeding direction is from the right to the left in the drawing. In the figure, the third and fourth from the left show the process of forming the workpiece 16 into a conical shape.
Further, the fifth and sixth from the left in the figure show the process of drilling a hole in the tapered surface of the conical workpiece 16. In this case, the bent portion 18a of the connecting member 18, which is a part of the carrier member 15, is bent,
It is positioned so that the tapered surface becomes the horizontal plane shown in the figure and is approximately perpendicular to a punch (not shown) that operates in the vertical direction. For this reason, with respect to the direction of punch movement,
Since the machining surface of the workpiece 17 is always located at a substantially right angle, machining can be performed in a stable state with a large extraction force. Further, the crank-shaped connecting member 18 can reduce deformation of the carrier member 15 in the longitudinal direction of the progressive mold layout, that is, in the direction perpendicular to the feeding direction. Therefore, during the feeding operation of the carrier member 15, the guide becomes stable, making it possible to feed more stably than before.

Further, the structure does not become complicated, such as by using a cam mechanism as in the past, and the range of normal press working can be expanded.
