Description

[Detailed Description of the Invention] The present invention relates to a press cutting die, and particularly to a press cutting die in which the angle between the upper blade and the lower blade can be adjusted.

Conventionally, a press cutting type has been proposed in which the angle between the upper and lower blades can be adjusted to enable shearing processing, but the conventional type has a complicated design that allows continuous fine adjustment of the blade angle. Since it is a complicated mechanism, it has the drawbacks of high cost and the possibility of errors occurring during use.

The purpose of this invention is to enable the upper blade to maintain two states with respect to the lower blade, for example, a parallel state and an inclined state.
This method eliminates the above drawbacks, and will be explained in detail below using examples.

1 to 4 are a perspective view and a configuration diagram of essential parts of an embodiment of a press cutting mold according to the present invention, and in the same figure, opposing U-shaped guide portions 2 are shown on both sides of a base material 1. Both sides of a flat upper blade 4 are fitted into the groove 3 of the guide portion 2.

A lower blade 5 is located on the side of the upper blade 4, and the lower blade 5 is attached to the base material 1.
It should be fixed with screws (not shown).

A holding plate 6 is fixed to the head of the upper blade 4 which is vertically movable, and presser holding parts 7 and 8 are fixed to both sides of this holding plate 6.

The presser holding part 8 is made of a plate material that extends in the direction of the substrate 1, and the presser holding part T includes an L-shaped frame 9 fixed to the side wall of the holding plate 6, and a frame 9 that extends in the direction of the substrate 1. It is made up of a rod 11 extending from the top and having a stopper 10 at its tip, a presser frame 12 supported by the rod 11 in a vertically movable manner, and a spring 13 that presses the presser frame 12 downward.

A frame 15 faces the tip of the plate 8 and is given upward accommodation by a spring 14.

At the front and back of the base material 1 are a mounting plate 16 on which the cutting member is placed, and a positioning section 21 consisting of a slide 19 and a stopper 20 that block one end of the cutting member 1γ and can slide on the shaft 18.
is fixed.

In addition, the mounting plate 16 and the positioning part 21 can be replaced with each other.

The guide part 2 consists of an L-shaped stator 22 and a stator 23 located at the end of the stator 22 and fixed to the stator 22 with a hinge 23a. The ascending upper blade 4 can be inserted into the groove 3 in a transverse direction, that is, in a direction perpendicular to the plane of the upper blade 4.

After insertion, the stator 23 is secured.

Therefore, by replacing the upper blade 4 with the groove 3, both of the cutting edges a and b can be made to face the lower blade 5.

The most important point for this embodiment is that when the lower blade 5 is fixed at an angle to the base material 1 and both sides of the upper blade 4 are replaced with the grooves 3, the opposing angle of the blade 4 to the blade 5 is The point is that the parallel state as shown in FIG. 3 and the inclined state as shown in FIG. 4 are maintained.

Therefore, according to the present invention, the upper blade 4 is inserted into the groove 3 of the guide part so that the opposing angles of the upper blade 4 and the lower blade 5 are parallel as shown in FIG. 3, and the pressure of the press machine is increased. By adding it to the blade 4, it is possible to punch out a relatively thin member 17 between the two blades 4 and 5.

In addition, if the upper blade 4 is replaced and a certain angle is set between the blades 4 and 5 as shown in FIG. 4, the member 17 can be sheared, and the relatively thick member 17 can be can be cut.

After cutting, the upper blade 4 is restored by the restoring force of a spring (not shown).

According to this embodiment, when cutting the member 17, the member 17 is held between the frame 7 and the lower blade 5 or the base material 1, and between the plate material 8 and the frame body 15.
Since the member 17 can be scissored between the two, there is no fear that the member 17 will move during or after cutting.

Moreover, since the member 17 to be cut falls vertically due to the cushioning effect of the frame 15 during cutting, the cut end becomes vertical.

Note that, as shown in FIGS. 3 and 4, the blades 4 and 5 are inclined greatly with respect to the surface of the base material 1 for convenience of explanation, but in reality, the angle of inclination is the same as that shown in the figures. As a result, there is no fear that the cut portion of the member will be deformed when it is cut.

Further, according to this embodiment, since the stopper 20 is provided that can move forward and backward with respect to the blades 4 and 5, the cutting length of the member 17 can be adjusted.

As explained above, according to the present invention, two types of cutting angles can be obtained by simply changing the direction of the upper blade, making the operation simple, and the simple structure prevents malfunctions.
＜, and the cost can be lowered.
