Abstract

PURPOSE:To obtain a titled die set which is small in weight and size, simple in structure and easy to adjust, by attaching a fitting board of adjustable vertical position to a support studded on the top face of a guide post, and mounting a punch holder driving section on the fitting board. CONSTITUTION:A die 4 is attached to a die holder 1 fixed to a stand 17 through a fitting stand 2, and at the same time, a guide post 5 is fixed. A support 10 is studded on the top of the guide post 5, and a punch holder 6 to which a punch 9 is attached is slidably attached through a guide bush 7 and a bearing 8. A fitting board 11 is adjustably attached to the support 10 consisting of a screw rod by a nut 12, and a driving source 14 such as a motor and a driving section 13 consisting of a main shaft attached to a punch holder 6 are mounted on the fitting board 11. By the above-mentioned constitution, the punch holder 6 is lowered with the punch 9 by operation of the driving section 3 against the repulsion force of a spring 16 and a work A such as a steel plate, etc. placed on the die 4 is worked by piercing, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a die set for press molds equipped with a die and a punch.

Conventionally, for example, 0. To punch a 10 mm diameter hole in a 3 mm color steel plate using a press, fix the die to the die holder of the die set, attach the punch to the punch holder, connect this punch holder to the ram of the press via the shank, and press the ram. The holes described above were punched out by the drive of the machine. However, in this case, there were disadvantages in that the press itself was large and expensive, and setup was not easy.

In order to eliminate such drawbacks, the present invention extends the guide post of the die set, attaches a mounting plate to it so that its vertical position can be adjusted, and also attaches a drive unit that drives the punch holder. To provide a die set for a press mold which is extremely lightweight, compact, and easily adjustable, and which becomes a press machine by simply adding it to a commercially available die set and attaching a required punch.

EMBODIMENT OF THE INVENTION Below, the die set for press molds which concerns on this invention is demonstrated in detail using drawing. FIG. 1 is an explanatory diagram showing a typical example of the above-mentioned Daicera (・), where I is a die holder and a mounting base 2.
is attached via a fixture 3 such as a bolt to the upper surface 1a.
Dice 4 of various shapes are attached to the dies 4 in a state where they can be easily attached and detached. 5
is fixed to the die holder using a guide post, such as a center post, a back post, or a structure as shown in JIS-B-5006. A punch holder 6 is slidably attached to the guide post via a guide bush 7 and a bearing 8. The punch holder 6 is also provided with an attachment hole 9a for attaching a punch 9, and an attachment hole 9b for attaching a main shaft of a punch holder driving section, which will be described later. Reference numeral 10 denotes a column whose lower end is planted and fixed on the top surface of the guide post 5 to form an extension of the guide post 5, and a mounting plate 1 is attached to the upper end.
1 is attached via a nut 12 so as to be adjustable in the vertical direction. The mounting plate 1 is used to mount a drive unit 13 for driving the punch holder 6, and is composed of a drive source 14 made of one type of holder and a main shaft 15, and fixes the drive source 14 to the mounting plate 11. The lower end of the main shaft 15 is fixed to the punch holder 6. A spring 16 serves to return the punch holder 6. Reference numeral 17 denotes a frame on which the mounting base 2 is attached.

Next, the operation will be explained.

Now, a color steel plate A with a thickness of 0.3 mm has a diameter of 3 mm.
Assume that a through hole of φ is to be drilled. For this purpose, an air cylinder is used as the drive source 14, the die 4 is attached to the die holder l, the punch 9 is attached to the punch holder 6, and the punch holder 60 stroke is set. Therefore, the air cylinder is driven by turning on the switch to smoothly lower the main shaft 15 in the direction of arrow A, thereby lowering the punch holder 6 as well.

Then, the bocchi 9 descends until it punches a predetermined hole in the color steel plate (product) A, and stops at the position shown in Fig. 2.Next,
The punching process is completed by raising the punch 9 in the direction of the arrow and returning it to the position shown in FIG. Also,
If the thickness of the product is different, the height H between the die holder 1 and punch holder 6 can be adjusted by adjusting the nut 12.
Select as desired.

What has been described above is only one embodiment of the die set for press molds according to the present invention, and the spring 16 may be removed or a stripper may be provided (not shown) as desired. Furthermore, although not shown in the drawings, the strut 10 may not be formed into a wire rod, but may have a structure in which threaded portions are formed only within a certain range of the upper and lower ends.

As described above, according to the die set for press molds according to the present invention, a press machine with the required stroke can be created by simply attaching the support, mounting plate, and drive part to a commercially available die set, and attaching the required punch and die to this. There are features that can be configured.

In addition, since the die set for press molds according to the present invention only has the above-mentioned components added to the commercially available die set, it is small, lightweight, has a simple structure, and can be manufactured at low cost. be. A further advantage is that the punch holder can be adjusted very easily depending on the thickness of the product.
