Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mold component attachment/detachment device that can attach and detach mold components such as punches and die plates to and from punch plates and die plates.

The attachment/detachment device of the present invention is capable of attaching and detaching various mold parts of different sizes to a single plate, and also allows easy positioning of punches and die punches during attachment.

(Prior Art) Conventionally, there is a punch of this kind as shown in FIG. 4, and a dive punch as shown in FIG. 5. As is clear from the respective drawings, each of these has a collar A for preventing slippage, and a notch B is formed in a part of the collar A.

This notch B connects the punch C to the punch plate.
When attaching the dive thread D to the die plate, use a directional punch C or dive thread D.
This is to ensure that the tip E and the receiving hole F of a punch (such as a punch whose tip E is square or oval, or a dive punch whose receiving hole F is square or oval) face a predetermined direction. Therefore, the position of the notch B is aligned with one side of the tip E of the square shape, or with one side of the receiving hole F of the square shape.

When using this punch C, insert it into the mounting hole H of the punch plate G as shown in FIG. Press key J to punch plate G
Fixed.

The die butt D is similarly attached to the attachment hole of the die plate (not shown).

(Problem to be solved by the present invention) However, since the conventional punch C and dive thread D are fixed to the punch plate and die plate respectively in such a way that they cannot be removed, punch C and dive thread D with different dimensions are required. In that case, you must purchase not only those but also the punch plate and die plate to which they are attached. Therefore, it is very uneconomical, and when the number of punch plates and die plates increases, it takes up a lot of space to store them, and it is troublesome to organize them.

(Purpose of the present invention) The purpose of the present invention is to make it possible to easily replace a conventional punch or die plate with a punch plate or die plate, to be able to attach it securely even without flange A, and to have a directional punch or die plate. The objective is to make the positioning simple and accurate.

(Means for solving the problem) As shown in FIG. 1, the attachment/detachment device of the present invention has a component insertion hole 3 in a plate 2 for mounting a mold component 1 such as a punch or a bushing, and a component insertion hole 3 in the insertion hole 3. Key 4 for fixing the inserted mold part 1 to the plate 2
and an adjustment screw 5 for moving the key 4 in a direction intersecting the axis of the component insertion hole 3.
The holder 6 to which the key 4 is attached has a return pin 8 for moving the key 4 in a direction in which it is removed from the locking groove 7 of the mold part 1.
and a spring 9 that presses the return pin 8, and the key 4 moves to the mold part 1 side by screwing the adjustment screw 5 into the key 4 side and fits into the locking groove 7 of the part 1, and the adjustment screw When 5 is returned, it is pushed by a return pin 8 pushed by a spring 9 and moves in a direction away from the locking groove 7.

(Example) The adjusting screw 5 in FIG.
It is tapered to match the taper of the receiving surface 11 of
When this adjustment screw 5 is screwed toward the key 4 side, its tip surface 10 presses against the receiving surface 11 of the key 4, and the key 4 moves laterally to the left in FIG. It is configured to be pushed into the locking groove 7.

Reference numeral 13 in Fig. 1 is a holding plate, which prevents the key 4 from being pushed upward when the adjustment screw 5 is screwed into the key 4 side, and ensures that the key 4 moves laterally to the left in Fig. 1. It is something that makes it possible.

The return pin 8 has its lower end surface 14 tapered to match the taper of the pressing receiving surface 16 of the fitting hole 15 formed in the key.

The punch 12 shown in FIG. 3 has a locking groove 7 formed on an outer peripheral surface 17 for positioning and preventing the key 4 from coming out, and is located at a position on the outer peripheral surface 17 in the same direction as the locking groove 7. A confirmation mark 18 for confirming the position of the locking groove 7 is formed on the surface.

Similarly to the punch 12, the dive punch 19 shown in FIG.
A confirmation mark 18 is formed in the same direction as the locking groove 7.

The locking groove 7 of the punch 12 has a directional tip 20
Align the locking groove 7 of the dive bush 19 to the specified position.
is aligned with a predetermined position of the directional receiving hole 21. Further, in both the case of the punch 12 and the dive bush 19, the locking groove 7 has a rear surface 22 formed in a planar shape as shown in FIGS. 2 and 3.

Confirmation mark 18 is punch 12, dive gun 1
9 to the punch plate 23 or die plate 2, respectively.
It is formed at a position where it can be seen from the outside of those plates when attached to the plates. Also, confirmation mark 1
8 is a groove having the same shape as the locking groove 7.

(Effects of the Invention) Since the attachment/detachment device of the present invention is constructed as described above, it has the following various effects.

(1) The structure is simple because a key 4 and an adjustment screw 5 are provided on the plate 2 to which the mold parts 1 such as punches and die guns are attached, and a return pin 8 and spring 9 are provided in the holder 6 to which the plate 2 is attached. It is simple and easy to put into practical use, and the key 4 can be attached and detached from the locking groove 7 by simply screwing in and returning the adjusting screw 5, so the attaching and detaching operation is also very simple.

(2) Since the key 4 is moved by screwing in and returning the adjustment screw 5, the movement of the key 4 can be finely adjusted, and therefore the degree of tightening of the mold part 1 can be adjusted. .

(3) When the return pin 8 is constantly pushed by the spring 9 and the adjusting screw 5 is loosened, the return pin 8 is automatically pushed and the key 4 is also automatically pushed back, so it is easy to remove the mold part 1. It is.

(4) Use a punch or button that has a locking groove 7 formed on its outer circumferential surface for positioning and retaining purposes, and the position of the locking groove 7 is located at the directional tip of the mold part 1. 20 or one that is aligned with the predetermined position of the directional receiving hole 21, the mold part 1 can be securely attached to the plate 2 by simply inserting the key 4 into the locking groove 7. It will be done. Moreover, just by attaching it to the plate 2, the tip 20 of the mold part 1 and the receiving hole 2 can be easily removed.
1 is automatically positioned in a predetermined direction,
Positioning becomes very easy and simple.

(5) A confirmation mark 18 is formed on the outer peripheral surface of the mold component 1 so that the position of the locking groove 7 can be confirmed at a position visible from the outside of the plate 2 when the mold component 1 is attached to the plate 2. If the mold part 1 is used, the mold part 1 can be attached to the plate 2 while looking at the confirmation mark 18, so that the mold part 1 can be attached and detached very easily.
