Description

The forming mold for side ends processing

The present invention relates to a forming mold for side end processing to form a flange (Flange) to the side end of the material, to describe in more detail to form a flange by performing a forming operation on one side end of the material bent into the upper plate and the lower plate ,

The upper and lower one side ends of the material are simultaneously formed in the horizontal and vertical directions so that the upper and lower flanges can be simultaneously formed through a single process.

To briefly explain the forming mold,

Forming molds are used when bending a workpiece or bending the edge of the workpiece in one direction.

Here, the background art to be solved by the present invention is in the forming mold for the side end processing to form a flange by forming the side end of the material in the forming mold.

Looking in detail with the accompanying drawings of the forming die for the side end processing,

The conventional side forming mold for briefly shown in Figure 6 is usually made of the upper mold body (a) and the lower mold body (b),

The upper mold body (a) is configured with an upper pad (1) for pressing the material (c), and the lower mold body (b) has a lower pad (2) supporting the material and the lower pad (2) side of the material ( A horizontal processing die 21 for molding c) is provided.

At this time, the lower pad (2) of the lower die body (b) is provided with one or more buffer springs 22 to the lower surface to perform a constant buffering action so that the lower pad (2) to a predetermined height before the molding operation Allow it to rise up.

Therefore, the forming die for the side end processing consisting of this configuration when the side end processing of the material,

Engage the material with the upper pad and the lower pad, and then simultaneously lower the upper and lower pads and form the material side end between them with a horizontal processing die (the material is lowered so that the side end is pushed upward by the horizontal processing die). To bend / form upwards.

However, the conventional side end forming mold having the above-described configuration / action is merely for forming the side end of the flat plate type, and in the case of the material (c) shown in FIG. there was.

That is, as shown in (a) of FIG. 8, the upper and lower flanges are formed at one end of each of the upper and lower plates of the material formed by bending the upper and lower plates, respectively. If you want to get

First, the first process is performed through a forming mold having a vertical processing die to obtain an upper flange c1 'at one end of the upper plate c1 of the material c.

This is again put into a forming mold having a horizontal processing die to form a lower flange (c2 ') at one end of the lower plate (c2) of the material (c).

This is a method of forming a double side forming mold for forming the flanges on one side end of the upper and lower plates of the material, respectively,

As the forming work was performed through two processes, the work efficiency was extremely lowered and the defect rate was increased due to the decrease in productivity and the difficulty of accurate positioning when moving the material between the forming mold and the forming mold.

In addition, when the flange is formed at one side end of the material shown in FIG. 8, the forming mold for side end processing is formed in two, so that two processes must be performed, resulting in excessive mold cost, and of course, delivery of the molding material. Had a problem raised up to cost.

As described above, the present invention has been invented to solve the problem that has arisen in forming an upper and lower flanges on one side end of the upper plate and the lower plate with respect to the bent material.

That is, the present invention forms a cam block having a vertical machining punching inclined forward and backward by pressing the upper side in a conventional forming die for forming the mold, the one end of the upper plate of the material is formed by a horizontal machining die When one side of the lower plate of the material is also simultaneously formed by vertical machining punching of the cam block so that the upper and lower flanges can be simultaneously formed through one process.

Looking at the means of the present invention for solving the above problems, as shown in the accompanying drawings, Figure 1,

Upper mold body (a) consisting of the upper pad (1) and lower mold body (b) consisting of the lower pad (2), which is engaged with the upper pad (1) to hold the material (c), and lower mold body (b) In the side forming part of the forming die for forming the horizontal processing die (21) on the upper side of the lower pad installation space (23) to allow the lower pad (2) to be moved in the vertical direction;

Cam block slide space (3) formed on the lower side of the lower die body (b) is installed in the horizontal processing die 21, the cam block slide space is located at the bottom of the horizontal processing die 21 and at the same time ( 3) To form a cam block operating space 31 associated with the depression to be installed and slide the cam block (4) bolted to the vertical machining punch 41 in the tip,

The cam block slide space 3 is provided with an elastic portion 32 on the bottom surface thereof so that the buffer fixing portion 42 of the lower surface of the cam block 4 is connected to the elastic portion 32 to have a constant buffering action. In addition, the guide rails 33 are attached to both sides of the elastic part 32 so that the slide of the cambler 4 can be stabilized.

The cam block 4 forms a lower surface thereof as a slide surface 43 having the same inclination angle as the guide rail 33 and simultaneously protrudes the step 44 on both sides thereof, thereby providing a cam block slide space 3. The separation prevented by the separation prevention plate 45 is bolted to the top,

The upper one side end of the cam block 4 is pushed by the driver a1 of the upper die body (a) and configured to protrude upward from the cam block transfer part 46 for flowing the cam block 4 thereafter. The transfer surface 47 is formed on the front surface of the sending section 46 at the same inclination angle as the pressing surface a2 of the driver a1 of the upper die body a,

Subsequently, the driver a1 is lowered to the side of the upper die body (a), that is, the upper die body (a) side which is in the same line position as the cam block 4 formed on the side of the lower die body (b). When the upper die body (a) acts downward, the driver (a1) is simultaneously lowered while pressing the feed surface (47) of the cam block transfer unit 46 to the pressing surface (a2), the cam block (4) ) Is pushed backward.

Here, the elastic portion 32 installed in the cam block slide space (3) is to be composed of a gas shock bar or a buffer spring.

In addition, the vertical machining punch 41 is formed at the top of the vertical machining punch 41 formed at the front end of the cam block 4 and the lower surface of the horizontal machining die 21 at one end of the lower die body b. When it flows obliquely backward by (4), it does not interfere with each other.

The present invention, which proposes the above-mentioned problem solving means, is characterized in that it simultaneously forms the side ends of the bent material consisting of upper and lower plates as shown in FIG. 8.

That is, in the forming die for the side-end processing, which was able to selectively form only one side end of the side end of the conventional flat plate-type material or the upper and lower plate side of the bent material,

The cam mold and the vertical punch are formed on the side of the forming mold to form the upper and lower flanges quickly and accurately by simultaneously forming the upper and lower ends of the bent material through one process.

Therefore, the present invention described above is to be bent as shown in Figure 8 to form a flange on the upper and lower sides of the material at the same time through a single forming the side end of the material consisting of the upper, lower plate, shortening the material work time and of course It is possible to increase the efficiency of mass production and work. Furthermore, if the cam block and the vertical processing punch presented above are symmetrically formed on both sides of the upper and lower mold bodies, the upper and lower ends of the material can be simultaneously formed. In order to maximize the efficiency and to apply the present invention, the angle of formation of the flange is more varied when the feed surface of the cam block transfer part and the driver pressing surface of the upper die body are formed opposite to the inclination angle suggested by the above-described solution. As a result, one forming mold provides a great effect to perform more forming operations.

On the basis of the accompanying drawings, it will be described in more detail as follows.

First of all, prior to the detailed description of the present invention, the disadvantages of the conventional side-end forming mold,

The conventional forming die for the side end processing is placed downward by placing the material (c) between the upper pad (1) of the upper mold body (a) and the lower pad (2) of the lower mold body (b) as shown in Figure 6, While conveying, the side end of the material c is upwardly formed into a fixed horizontal processing die 21 to form a flange.

Therefore, when the conventional side forming mold is a flat material, the side forming can be performed without any problem, but when the target material formed by bending the upper and lower plates as shown in FIG. Had

That is, when it is necessary to form a flange by forming the upper and lower one end of the material, in the conventional forming mold described above, the flange is formed only on the upper end side by a fixed horizontal die and the flange is formed on the other lower end. I had a problem that I could not give.

As a result, the upper flange of the upper plate of the raw material was formed by the primary process through the above process, and the lower flange was formed on the lower side of the raw material by the secondary process through another forming mold.

As described above, in the related art, when forming the material shown in FIG. 8, a second process must be performed through a separate forming mold, thereby reducing work time and production efficiency, as well as increasing a defective rate and manufacturing cost of a product. Had the problem of elevating.

However, unlike the conventional forming mold, the present invention simultaneously forms one end of the upper plate and the lower plate of the material as described above so that the upper and lower flanges can be simultaneously formed in one process.

To describe this in more detail, as shown in FIG. 1, the upper pad 1 is configured with the upper mold body a and the lower pad 2 configured to engage the upper pad 1 to hold the material c. The lower die body (b) and the lower side of the lower die body (b), that is, the lower pad (2) is installed horizontal processing die (top) on the upper side of the lower pad installation space 23 to be moved in the vertical direction ( 21) Forming mold for side-end machining by installing

One side portion of the lower die body (b) having the horizontal machining die 21 installed, that is, as shown in FIG. The cam block slide space 3 formed to be inclined and the cam block operation space 31 positioned below the horizontal processing die 21 and associated with the cam block slide space 3 are recessed to form a vertical machining punch at the tip thereof. (41) is configured to be installed and slide the cam block (4) is bolted,

The cam block slide space 3 is provided with an elastic portion 32 to the bottom surface, the buffer fixing portion 42 of the lower surface of the cam block 4 is connected to the elastic portion 32 to perform a constant buffering action. Of course, the guide rail 33 is attached to both sides of the elastic portion 32 so that the slide of the cam block 4 can be stabilized.

Here, the elastic portion 32 is connected to the buffer fixing portion 42 provided on the lower surface of the cam block 4 when the cam block 4 is slide, stably plan the slide and at the same time the cam block ( 4) is to return to the original position automatically after operation to wait for the next work.

At this time, the elastic portion 32 is composed of a gas shock bar or a buffer spring (not shown).

In addition, the cam block 4 is placed in the cam block slide space 3 and the tip thereof is positioned in the cam block operating space 31 so that the vertical machining punch 41 of the tip of the cam block 4 is horizontally processed. The cam block operating space 31 is moved in and out by the slide of the cam block 4 in the state located below the die 21.

That is, the cam block 4 is formed as a slide surface 43 having the same inclination angle as the guide rail 33 as shown in Figure 5 so that the cam block 4 slides along the guide rail 33 Make it easy,

Protruding step (44) on both sides thereof so that the separation can be interrupted by the separation prevention plate 45 bolted to the upper end of the cam block slide space (3),

The cam block conveying part 46 protrudes upward at one upper end of the cam block 4, and the conveying surface has the same inclination angle as the pressing surface a2 of the driver a1 of the upper die body a in front of the cam block 4. It constitutes 47.

Here, the cam block transfer portion 46 protruding from one upper end of the cam block 4 is

This is to give the cam block 4 to be slid horizontally by pressing the driver a1 by converting the vertical movement of the downwardly moving driver a1 into the horizontal motion.

The feed surface 47 and the pressing surface a2 having the same inclination angle are formed on the front surface of the cam block transferring portion 46 and the lower portion of the driver a1, and the feeding surface 47 is pushed by pressing the pressing surface a2. As a result of this phenomenon, the direction of movement can be achieved.

Subsequently, the driver a1 is lowered to the side of the upper die body (a), that is, the upper die body (a) side which is in the same line position as the cam block 4 formed on the side of the lower die body (b). When the upper pad 1 of the upper mold body a is lowered, the driver a1 is simultaneously lowered and the feed surface 47 of the cam block transfer part 46 is pressed against the pressing surface a2. The cam block 4 was pushed / moved backward from the initial position.

In the present invention described above, when simultaneously forming the upper and lower flanges (c1 ') and (c2') at one end of the upper and lower plates (c1) and (c2) of the material (c) shown in FIG.

The above material (c) is engaged between the upper pad 1 of the upper mold body (a) and the lower pad 2 of the lower mold body (b), and then simultaneously lowered so as to lower the material (c) as shown in FIG. Forming the upper plate one end by a fixed horizontal processing die 21 to obtain an upper flange (c1 '),

At the same time, while the driver a1 formed on the upper pad 1 side of the upper die body a descends simultaneously with the upper die body a, the feed surface 47 of the cam block transfer unit 46 is moved by the driver ( Pressing the pressing surface a2 of a1) pushes the feed surface 47 of the cam block 4 to the rear so that the cam block 4 slides inclined to the rear position.

Then, the vertical machining punch 41 bolted to the tip of the cam block 4 simultaneously moves backward with the cam block 4, forming one end of the lower plate c2 of the material c (outer plate outside). Push the direction to be bent) so that the lower flange c2 'is formed at the same time as the upper flange c1'.

In the present invention, the material of FIG. 8, which has been carried out through two processes in the related art, can be obtained by only one process, and can be said to have novelty and progress in technology.

In addition, although the present invention is not shown in the drawings, it is apparent that various forming operations can be performed through the above configuration / action.

In other words, when the present invention is configured symmetrically with the upper and lower mold bodies, the upper and lower ends of the material can be simultaneously formed, as well as the transfer surface of the cam block transfer part is opposite to that shown in FIG. In other words, if the cam block is formed symmetrically on the back of the conveying unit and the pressing surface of the driver is also formed at the same position and angle as the conveying surface, the cam block is pushed forward by the pressing of the driver, forming the material as opposed to the above action. By working, it is possible to form a flange at one end of the lower plate to a position symmetrical with the upper plate of the material.

In addition, the slide angle of the cam block can be variously changed according to the forming properties of the material can be carried out a variety of forming operations.

In addition, when the configuration of the present invention is configured on both sides of the general molding mold, it is possible to provide an increase in the efficiency of the work that can be formed at the same time as forming the flange at the same time and the possibility of mass production.

Therefore, the above-described embodiment will be within the scope of the present invention because it can be predicted by anyone skilled in the art through the present invention.
