Description

[Detailed description of the invention] A. Purpose of the invention a. Industrial application field The present invention relates to a simple press for attaching fasteners such as hooks, eyelets, caulks, and rivets to fabric or other materials, and is particularly characterized by molds. This relates to a simple press having a

b. Prior Art Generally, in a simple press, a lower mold is attached to a lower pedestal, and an upper mold is attached to a shaft that can be raised and lowered, and the shaft is pushed down with a lever to lock the press between the two molds. It has a structure in which other parts are attached to fabric, etc.

By the way, among the conventional upper and lower molds, the upper mold has a predetermined mold on the cylindrical lower surface and a male thread is formed on the upper part, and the male thread is screwed into the female thread hole at the bottom of the shaft rod. It has been installed and installed. The lower mold has a predetermined mold on the upper surface of the short cylindrical shape, and the lower half of the cylindrical shape is formed with a small diameter, which is engaged with the through hole of the pedestal, and the small diameter stepped portion is engaged with the periphery of the through hole. It has been stopped and installed. For example, in something like a hook, which is made up of two pairs, a male and a female, the male hook consists of two parts called a shank and a tenon, and the female part also consists of two parts called a head and a spring. Therefore, for example, to attach a male hook to a piece of fabric, you need an upper mold for a gecko and a lower die for a tenon, and to attach a female hook to the other fabric, an upper mold for a spring is required. A mold and a lower mold for the head are required. Therefore, due to its structure, manufacturing is time-consuming and the material cost is high, and at least two sets of four molds are required just for hooks. If a simple mold press is used to attach the molds, there are problems such as it is difficult for an amateur to understand the combination of molds and how to use them.

c. Problems to be solved by the invention The present invention aims to solve the problems of the conventional tabletop simple presses as described above.
In other words, the aim is to simplify and miniaturize the structure of the mold, reduce the number of required molds by half, reduce costs, and create a tabletop mold that is easy to understand even for amateurs. The aim is to provide a simple press.

B. Structure of the invention a. Means for solving the problems The tabletop simple press of the invention has a lower mold 1 having a short cylindrical shape, and a male mold 5 with a convex portion on one side and a concave portion on the other side. Female molds 6 are respectively formed, while the upper mold 2 is formed into a slightly longer cylindrical shape, and the male molds 5 and 5 of the lower mold 1 are formed.
Molds 7 and 8 corresponding to the female mold 6 are formed respectively, and the lower mold 1 can be engaged and placed on the pedestal 3 of the press, and a lower mold receiving part 9 is provided with a small hole 10 in the center of the lower part. A part of the upper mold 2 can be fitted to a shaft rod 4 which can be raised and lowered, has a locking means 12, and has an upper mold fitting hole 11 with a small hole 13 in the center of the upper part. It is something that is formed.

In the above structure, the mold of the upper mold 2 is usually a female mold 7 with a concave portion corresponding to the male mold 5 of the lower mold 1 on one side, as shown in FIG.
A male mold 8 with a convex portion corresponding to the female mold 6 is used. However, when trying to attach it to cloth or other materials,
Depending on the type of caulking, rivet, etc., male molds 8, 8 with convex portions having different outer diameters may be formed on the upper and lower surfaces of the upper mold 2, respectively, as shown in FIG.

A spring ring 14 for holding the workpiece may be provided on the inner periphery of the recess of the female mold 7 of the upper mold 2, or a spring ring 14 for holding the workpiece may be provided on the outer periphery of the female mold 7 of the upper mold 2. It is desirable to provide a holding cylinder 15 made of an elastic material so that it can be attached and detached.

The locking means 12 in the fitting hole 11 of the shaft rod 4 may be, for example, provided with a rubber or spring ring on the inner periphery, a small ball pushed out by a spring (not shown), or a machine screw inserted from the outside. It refers to a means of restraining someone.

In the figure, 16 is a tenon, which is one of the processed parts that make up the hook, 17 is also a gecko, and 18
is the head, and 19 is the spring.

b. Effect The state of use of the present invention will be explained. For example, a hook is made up of two pairs, a male hook and a female hook, and the male hook is the two workpiece parts called the tenon 16 and the spring 17, and the female hook is called the head 18 and spring 19. A case will be described in which two workpieces are attached to cloths 20 and 21, respectively.

First, to attach the male hook to the cloth 20, as shown in Fig. 1, the lower mold 1 is connected and placed in the receiving part 9 of the pedestal 3 so that the male mold 5 with the convex part faces upward. ,
On the other hand, the upper mold 2 is fitted and fixed into the fitting hole 11 of the shaft rod 4 so that the female mold 7 with the concave portion faces downward. In this state, as shown in FIG. 7, the tenon 16 is placed on the lower mold 1 with its protruding part facing upward, and the tenon 17 is engaged with its protruding part in the recess of the upper mold 2.・Hold it. And cloth 2 is placed between the tenon 16 and the tenon 17.
0 and press a lever (not shown) to lower the shaft rod 4. As a result, the tenon 17 held in the upper mold 2 is pressed against the tenon 16 with the cloth 20 in between, so that the protruding part of the tenon 16 is folded back within the bulge of the tenon 17 and the tenon is held with the cloth 20 in between. 16 and Genko 17 unite to form a male hook.

Next, in order to attach the female hook to the cloth 21,
As shown in the figure, turn the lower mold 1 upside down and make a female mold 6 with a concave part.
On the other hand, the upper mold 2 is also turned upside down and attached to the shaft rod 4 so that the male mold 8 with the convex portion faces downward. In this state, as shown in Figure 8,
The head 18 is placed on the lower mold 1 with the protrusion facing upward, and the spring 19 is engaged and held by the protrusion of the upper mold 2 through the central hole. Then, place the cloth 21 between the head 18 and the spring 19, press the lever, and press the shaft rod 4.
By lowering the head 18, the protruding part of the head 18 is folded back inside the spring 19, and the head 1 is folded back with the cloth 21 in between.
8 and spring 19 are integrated to form a female hook.

As mentioned above, if the female mold 7 of the upper mold 2 is provided with a spring ring 14 for holding the workpiece or a cylinder made of an elastic material 15, the female mold 7 is provided with a forceps 16.
Other workpieces can be easily held.

The above shows the male mold 5 and female mold 6 of the lower mold 1, and the upper mold 2.
This is a case where the male and female hooks are attached to the cloths 20 and 21 using the female die 7 and male die 8. However, depending on the type of hook, the upper mold 2 of male molds 8 and 8 may be used for both the upper and lower surfaces as shown in FIG. Furthermore, when attaching a single item such as an eyelet, caulking, or rivet to cloth or the like instead of consisting of a male and female hook like a hook, the usage of the upper mold 2 and the lower mold 1 is slightly different. That is, although the upper and lower molds 2 and 1 are used as described above, the upper and lower molds 2,
Among the upper and lower surfaces of 1, for example, one corresponding male type and female type are used for small-sized eyelets, and the other corresponding male and female types are used for large-sized eyelets. It can be used for caulking and rivets.

C. Effects of the invention As is clear from the above, the present invention has the following effects, unlike the conventional ones.

a The number of molds can be halved. That is, the conventional simple press mold has a structure in which the upper mold is screwed onto the shaft with an upper male screw, and the lower mold has its small diameter stepped portion engaged with the through hole of the base. Due to its male thread and small diameter step, only the bottom surface of the upper mold can be used as a mold, and only the top surface of the lower mold can be used as a mold.
Only one type of processing can be performed with one set of upper and lower molds. For example, in the case of a hook, in which the male hook and female hook are each made up of two parts, there is one set of upper and lower molds for attaching the male hook to the cloth, and another set of molds for attaching the female hook to the cloth. Four types of molds were required: upper and lower molds.

In contrast, in the present invention, the upper mold is cylindrical with no male threads, and is fixed with a locking means on the shaft of the press, so that both the upper and lower sides of the upper mold have male screws. A mold and a female mold are formed. On the other hand, the lower mold also has a short cylindrical shape without the small-diameter step, and is engaged and fixed in the stepped hole of the pedestal, forming male and female molds on both the upper and lower sides of the lower mold. It has been done. Therefore, even when there is a male and female hook, such as a hook, one set of upper and lower dies is used to attach the male hook to the fabric using one male and female die, and attach the male hook to the cloth using the other male and female die. The female can be attached to the cloth. Therefore, unlike the conventional method, the number of molds required to be manufactured, stocked, and held can be halved.

b. The manufacturing cost of molds can be reduced. In other words, the conventional mold for hooks, for example, requires two upper and lower molds for the male hook and two for the female hook, resulting in a total of 4 molds.
In addition, it is necessary to form a male thread in each upper mold and a small diameter stepped part in each lower mold, and the material cost is equivalent to 4 pieces, so the manufacturing cost is high. arrived.

However, in the present invention, the number of molds can be reduced to half as described above, and the shape of each mold is simple, so that manufacturing costs can be reduced and mass production is also excellent.

c It becomes easier to understand how to use it. In other words, there are a large number of conventional molds, so as this type of tabletop simple press has come to be used in households in recent years, it has become difficult for householders to choose a combination from among many molds. is difficult.

However, in the present invention, the number of molds is halved, and molds related to the upper and lower surfaces of each mold, for example, as described above, a mold for a male male with a hook on one side of the upper mold,
A mold for the female hook spring can be formed on the other side, a mold for the tenon of the male hook can be formed on one side of the lower mold, and a mold for the head of the female hook can be formed on the other side. Therefore, even a householder can easily select the necessary mold, making it easier to use.
