A lower mold 2 and an upper mold 6 illustrated in FIG. 10 are mounted between the lower surface plate 1 and the upper surface plate 10. At the time of mounting, the lower surface plate 1 and the upper surface plate 10 are located at the top dead center.

As illustrated in FIG. 10 with a part cut away, a lower mold 2 and an upper mold 6 are inserted into a bush 7 of the upper mold 6 and are embedded in the lower mold 2. The post 5 allows the relative movement along the pressing direction, which is the longitudinal direction of the guide post 5, but restricts the relative movement in the direction perpendicular to the pressing direction.

A lower mold 2 and an upper mold 6 illustrated in FIG.
An operation of mounting between the lower surface plate 1 and the upper surface plate 10 illustrated in FIG. 9 will be described. First, the lower mold 2 and the upper mold 6 of FIG. 10 are manually placed on the lower platen 1 of FIG.
Then, the upper mold 6 is lifted to the upper surface plate 10 while the lower mold 2 is pressed toward the lower surface plate 1 by hand. Upper mold 6

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a cross-sectional view illustrating a structure of a press device according to the present embodiment. The upper platen 28 and the lower platen 21 provided in the press device are composed of an upper mold 25 and a lower mold 22.
At the time of mounting, only movement along the press direction, which is the vertical direction toward the drawing, is possible, and movement in the direction perpendicular to the press direction is prohibited. In this manner, the relative positions of the upper stool 28 and the lower stool 21 in the direction orthogonal to the pressing direction are determined. When the lower mold 22 is referred to as a “first mold”, the upper mold 25 corresponds to a “second mold”.

The upper platen 28 and the lower platen 21 respectively
Hook-shaped claws 28a and 21a are provided in cross section. The hooks 28a and 21a having a hook-like cross section extend in a direction orthogonal to the cross section. The grooves 28b and 21b are formed by the bases of the claws 28a and 21a and the upper platen 28 and the lower platen 21, respectively.
Are formed.

The upper mold 25 and the lower mold 22, which are fixed to the upper platen 28 and the lower platen 21, respectively, are provided with flanges 25a and 22a so as to have a T-shaped cross section. Tsuba 25
a, 22a extend in a direction orthogonal to the cross section, and fit into the grooves 28b, 21b as shown. Grooves 28b, 2
The size of 1b is set so that the gaps left in the grooves 28b and 21b when the flanges 25a and 22a are inserted are small. The vertical and horizontal movements of the upper mold 25 and the lower mold 22 inserted into the grooves 28b and 21b, respectively, toward the drawing are regulated by the claws 28a and 21a and the bases of the upper stool 28 and the lower stool 21, respectively. Have been.

The procedure for mounting the lower mold 22 and the upper mold 25 on the lower surface plate 21 and the upper surface plate 28, respectively, will be described. First, with the flange 22a fitted in the groove 21b, the lower mold 22 is slid on the lower platen 21 in a direction perpendicular to the cross section. The slide is made manually or by mechanical means. The small gap between the flange 22a and the groove 21b allows the lower mold 22 to slide smoothly.

The lower mold 22 has a hole 2 penetrating vertically.
The lower platen 21 is provided with a hole 24b on the surface to which the lower mold 22 is fixed. The locations where the holes 24a and 24b are drilled are set so as to conduct with each other when the lower mold 22 and the lower stool 21 are adjusted to the position to be fixed.

The lower mold 22 is slid and the holes 24a, 24
When b is conducted, the positioning pin 24 is inserted. The positioning pin 24 stops in a state where the positioning pin 24 extends over the lower mold 22 and the lower platen 21. The movement of the lower mold 22 in a direction perpendicular to the cross section of FIG. 1 which cannot be restricted by the claw 21 a is restricted by the positioning pin 24.

As described above, the lower platen 21 of the lower mold 22
Is fixed by the claw 21a and the positioning pin 24. In addition, by using a plurality of positioning pins 24 as illustrated in FIG. 1, a lower mold slightly allowed by a minute gap between the flange 22 a and the claw 21 a in a direction orthogonal to the pressing direction. Restriction of the rotation of the motor 22 is easily realized.

After the lower mold 22 is fixed to the lower platen 21, an operation of fixing the upper mold 25 to the upper platen 28 is performed. Similarly to the case of fixing the lower mold 22, the upper mold 25 is slid in a direction perpendicular to the cross section of FIG. 1 in a state where the flange 25a is fitted in the groove 28b. Like the holes 24a and 24b, the upper platen 28 has a hole 29a penetrating it vertically.
Holes 29b are formed on the upper surface of the upper mold 25, and the positioning pins 29 are inserted into the holes 29a and 29b when the upper mold 25 slides to a fixed position. As described above, the upper mold 25 is provided with the claws 28a in the vertical and horizontal directions.
The direction (including the rotation direction) orthogonal to the cross section is fixed to the upper surface plate 28 by a plurality of positioning pins 29 by the upper surface plate 28.

In the structure of the present embodiment, a direction perpendicular to the pressing direction of the upper mold 25 and the lower mold 22 is used without using the conventionally required guide post 5 as illustrated in FIG. Is performed. By eliminating the need for conventional components, the cost of the press is reduced.

Further, in the structure of the present embodiment, the lower mold 22 and the upper mold 25 are fixed with the claws 21a, 28a,
Lower surface plate 21, upper surface plate 28, and positioning pins 24, 2
9 respectively. The conventional fixing screw 4 illustrated in FIG. 11 becomes unnecessary, and the conventional dedicated tool and labor required for tightening the fixing screw 4 are omitted, and the time required for mounting the mold is reduced. Since a special tool is not required, the special tool cannot be left between the upper mold 25 and the lower mold 22, and an operator does not perform an erroneous operation when tightening. Further, it is possible to prevent the die and the press device from being damaged due to forgetting to tighten the screws.

When the lower mold 22 and the upper mold 25 are fixed, the surface of the lower platen 21 to which the lower mold 22 is fixed is
The distance H between the upper platen 28 and the surface to which the upper mold 25 is fixed.
Is the same as the sum of the heights H22 and H25 of the lower mold 22 and the upper mold 25 in the example of FIG. This is to prevent the upper mold 25 from receiving a vertical pressing force by the lower mold 22 and the upper surface plate 28 in order to slide the upper mold 25 smoothly.

However, securing the interval H by the sum of the heights H22 and H25 does not have to be performed while both the lower mold 22 and the upper mold 25 are fixed.
Since the upper mold 25 slides between the lower mold 22 and the upper surface plate 28 after the lower mold 22 is fixed to the lower surface plate 21 as described above, the space is only provided when the upper mold 25 is mounted. H is height H
What is necessary is just the sum of 22, H25.

Further, from the viewpoint of not generating a pressing force, as illustrated in FIG. 2, the lower mold 22 and the upper mold 22 are placed in a state where the lower platen 21 and the upper platen 28 are located at the top dead center. The mold 25 may be fixed. The top dead center is a dead center in which the lower surface plate 21 and the upper surface plate 28 are further isolated. FIG. 2 shows the lower platen 21 when the upper mold 25 is mounted.
FIG. 3 is a cross-sectional view illustrating a configuration in which an upper platen 28 is located at a top dead center. In this case, as shown, the interval H is larger than the sum of the heights H22 and H25.

In the example of FIGS. 1 and 2, the upper mold 25
No pressing force acts between the upper mold 25 and the lower mold 22, and no frictional force is generated between the upper mold 25 and the lower mold 22. Therefore, the sliding of the upper mold 25 in the groove 28b is smooth.

FIG. 3 shows a lower platen 21 and an upper platen 2.
FIG. 8 is a cross-sectional view illustrating a configuration in which an upper mold 25 is mounted in a state where 8 is located at a bottom dead center. The bottom dead center is a dead center in which the lower stool 21 and the upper stool 28 are closer together. In this case, a pressing force acts between the upper mold 25 and the lower mold 22, and these heights are equal to the original heights H25 and H25.
It is slightly smaller than 22. In FIG. 3, the height is exaggerated for ease of understanding. Therefore, the interval H is smaller than the sum of the heights H22 and H25. When the upper mold 25 is mounted at the bottom dead center, the upper mold 25 cannot slide smoothly due to the frictional force generated by the pressing force.

From the above, in order to mount the mold 25 smoothly, the upper platen 28 and the lower platen 21 are spaced apart by the distance H.
May be located between the position where the heights H25 and H22 are the sum of the heights and the position that is the top dead center.

However, if the distance H between the upper platen 28 and the lower platen 21 is increased, the distance between the upper die 25 and the lower die 22 is necessarily increased. Then, there is a possibility that the objects may be left in the space between the upper mold 25 and the lower mold 22 and the molds 22 and 25 may be damaged. Therefore, as illustrated in FIG. 1, the interval H is set to be exactly the sum of the heights H22 and H25, or a space is left between the lower mold 22 and the upper mold 25 as illustrated in FIG. 2. Even if it is set, it may be set to be slightly larger than the sum (for example, about several mm to 1 cm). Thus, the upper surface plate 28 and the lower surface plate 21
Is set, the upper die 25 slides immediately above (directly above) the lower die 22, and it is possible to avoid leaving an object between the upper die 25 and the lower die 22 beforehand. You.

In the above example, the setting of the interval H when the upper mold 25 is mounted has been described. However, when the upper mold 25 is pulled out from the upper surface plate 28, the interval H is set to the height H2.
The upper stool 28 and the lower stool 21 are positioned so as to be equal to or greater than the sum of H22 and H22. As a result, the upper mold 25 can be pulled out smoothly.

The fixing of the upper mold 25 and the lower mold 22 in the direction perpendicular to the drawing is finally performed by the positioning pins 24 and 29. Accordingly, considering that the lateral movement of the upper mold 25 and the lower mold 22 toward the drawing is restricted by the claws 21a and 28a, the claws 21a and 28a It is sufficient to be at both ends in the direction.

However, in order to prevent the lower die 22 from slipping out of the lower die 22 by vibrating when the lower die 22 is inserted into the groove 21b, for example, the claw 21a is inserted into the groove from both sides of the lower die 22. You may extend to the back side toward the drawing of 21b. Due to the extension, the lower mold 22 stops at the depth of the groove 21b.

Further, a handle attached to a drawer such as a desk may be attached to the lower mold 22 and the upper mold 25. When pulling out the lower mold 22 and the upper mold 25 from the grooves 21b and 28b, respectively, in a direction orthogonal to the cross section shown in FIG.

In the example shown in FIG. 1, the grooves 21b and 28b having the insertion opening on the front side of the drawing extend in the same direction, and the lower mold 22 and the upper mold 25 are parallel to each other.
b, 28b. However, for example, groove 2
The slot 28b may be provided on the left side as viewed in the drawing and the groove 28b may extend in the horizontal direction as viewed in the drawing while the insertion opening 1b is located on the front side of the drawing.

In this case, the lower mold 22 and the upper mold 25 are inserted in different directions from each other, but the planes on which the lower mold 22 and the upper mold 25 move are parallel to each other as in the example of FIG. Yes, the effects of the present invention can be obtained as they are.

It is to be noted that the first and second mold fixing bases and the first and second fitting grooves according to the first aspect include a lower platen 21 and an upper platen 28 and grooves 21b and 28b, respectively. It is. Further, the first and second insertion holes and the insertion body according to the fourth aspect are concepts including holes 24a, 24b, 29a, 29b and positioning pins 24, 29, respectively.

Embodiment 2 In the first embodiment,
The preferred size of the interval H between the upper stool 28 and the lower stool 21 has been described. In the present embodiment, a mechanism for setting the interval H to a desired size will be described. Hereinafter, the same configurations and structures as those already described have the same reference characters allotted, and description thereof will not be repeated.

FIG. 4 is a cross-sectional view illustrating the structure of the press device according to the present embodiment. The press device shown in the figure is the same as the press device shown in FIG. 1 except that a switch S is added, and the configuration of the other parts is the same.
Hereinafter, the function of the switch S will be described.

First, in a state where the upper mold 25 and the lower mold 22 are not mounted, the upper platen 28 and the lower platen 21 are
Is located at the top dead center. Next, the upper platen 28 is lowered downward by a motor of a press device (not shown) downwardly toward FIG. As the upper platen 28 descends, the interval H gradually decreases.

The switch S is arranged at a position where it comes into contact with the upper platen 28 when the interval H reaches a desired value. When the interval H gradually decreases to a desired value, the switch S is pressed as shown by the upper platen 28, and a corresponding signal is given to a motor (not shown). The motor stops at the same time as the input of the signal, and the interval H is maintained at the desired value. In this state, the lower mold 22 and the upper mold 2 are
5 may be sequentially mounted.

When the upper platen 28 further descends, the switch S rotates as indicated by the arrow at the contact portion with the upper platen 28 as it descends. Therefore, when the upper platen 28 is lowered to the bottom dead center when the press device is actually used,
The switch S does not hinder the movement of the upper stool 28.

However, if the switch S is hit each time the press device is used, the life of the switch S is shortened.
Therefore, instead of the switch S, for example, a light receiver having the function of a light source may be provided. This light receiver is provided in the portion where the switch S is located in FIG. 4, and the light is transmitted from left to right as viewed in the drawing.

When the upper platen 28 is located at the top dead center,
No reflected light returns to the receiver. However, when the upper platen 28 reaches a desired position by descending, the upper platen 2
The light is reflected by 8, and the reflected light is detected by the light receiver. By stopping the operation of the motor in response to the detection of the reflected light, the same effect as that of the switch S can be obtained.

The load on the user is reduced by automatically setting the positions of the upper stool 28 and the lower stool 21 before the dies 22 and 25 are mounted as described above. Further, the user does not need to be near the press device.

The setting means according to claim 2 is a concept including a switch S and a light receiver.

Embodiment 3 In the second embodiment,
A configuration is shown in which means for detecting the position of the upper stool 28 is provided to perform alignment. In the present embodiment, a description will be given of a configuration for performing positioning by detecting the amount of movement of the upper stool 28.

FIG. 5 shows an upper surface plate 28 according to the present embodiment.
4 is a flowchart illustrating a configuration of a setting unit (controller) for setting a relative position of a lower stool 21;
The setting means is provided together with a motor for moving the upper stool 28.

First, in step SP1, the setting means is turned on. Next, in step SP2, the motor is driven to lower the upper stool 28. The amount of lowering (moving amount) of the upper stool 28 is counted as the number of pulses by an encoder provided in the setting means.

In step SP3, the setting means determines whether the count value of the encoder has reached the set value. If “NO” is determined, step SP
The operation 2 is continued, and the upper stool 28 continues to descend. On the other hand, if "YES" is determined, the driving of the motor is stopped by the setting means, and the lowering of the upper stool 28 is stopped in step SP4.

By setting the set value so that the upper surface plate 28 is at a desired position when the count value reaches the set value, the interval between the upper surface plate 28 and the lower surface plate 21 is automatically set. This is possible as in the second embodiment. When the dies 22, 25 are mounted, the setting means is turned off in step SP5 so that the upper stool 28 does not move.

Embodiment 4 In the first embodiment,
As illustrated in FIG. 1, positioning pins 29, 24 and holes 24a, 24b, 29a, 29b into which these are inserted.
The upper surface plate 28 and the lower surface plate 21 of the molds 25 and 22
Each is fixed in a direction perpendicular to the drawing.
In the present embodiment, a configuration is described in which the direction is fixed without using a positioning pin and a hole.

FIG. 6 is a front view illustrating the structure of the press device according to the present embodiment. For simplicity of illustration, only the lower platen 21 and the lower mold 22 are shown. Hereinafter, these are simply referred to as a surface plate 21 and a mold 22. The structure of the mold 22 and the surface plate 21 shown in the figure is almost the same as the structure of FIG. 1 except that the holes 24a and 24b illustrated in FIG. 1 are not drilled. Hereinafter, differences will be described.

A straight path guide table 31a, which is movable in the direction in which the grooves extend, is fitted into a straight path guide 31 which is a groove formed in the surface plate 21 in the horizontal direction toward the drawing. The pressing tool 3 is placed on the straight guide table 31a.
2, a roller 32a is provided on both sides of the pressing tool 32 on the claw 21a side.

First, the straight path guide table 31a is
The mold 22 is inserted into the groove 21b in the same manner as in the first embodiment, leaving the entrance of the mold b. An extension of the claw 21a existing at both ends of the groove 21b in the plan view of FIG. 6 is provided on the back side of the groove 21b toward the drawing, and the mold 22 moves in the direction from the front surface to the back surface of the drawing. Is stopped by the extension. The movement of the mold 22 in the groove 21b in the horizontal direction and the vertical direction is restricted by the claw 21a. That is, the movement of the mold 22 in this state is free only in the direction from the back surface to the front surface in the drawing.

The lateral gap between the mold 22 inserted into the groove 21b, the nail 21a and the platen 21 is smaller than that of the first embodiment illustrated in FIG.
The size of a is set. Therefore, except that the movement from the back surface to the front surface in the drawing is free, the groove 21
It can be said that the fixing of the mold 22 inserted into the mold 22 in the plane direction orthogonal to the pressing direction has already been performed.

Next, the linear motion guide table 31a is moved rightward as viewed in the drawing, and positioned at the entrance of the groove 21b as illustrated in FIG. FIG. 7 is a front view illustrating a structure in which the linear guide table 31a is located at the entrance of the groove 21b. The translation guide table 31a is moved by moving means (not shown) or manually. With the movement of the straight guide table 31a, the roller 32a moves while rolling on the surface of the mold 22 smoothly. In this manner, the roller 32a presses the mold 22 from the front surface to the rear surface in the drawing.

The direct guide table 31a is connected to the direct guide 3
By fixing on the top 1, the fixing of the mold 22 by the roller 32a is completed. Thus, the mold 22
Is positioned with respect to the surface plate 21. When the mold 22 is pulled out, the above operation may be performed in reverse.

As described above, the holes 24a, 24a in FIG.
b and the function of the positioning pin 24 are changed to a straight guide 31, a straight guide table 31a, a pressing tool 32, and a roller 32.
It is possible to substitute the fixing jig F1 made of a. In the above description, the fixing of the lower mold 22 is taken as an example, but of course, a fixing jig having the same structure as the fixing jig F1 is provided on the upper surface plate 28, and the upper mold 25 is fixed by the fixing jig. It is also possible to do.

In the structure of the first embodiment, as illustrated in FIG.
Has to be performed after the insertion. However, there is no such restriction in the structure of the present embodiment. It is also possible to insert the lower mold 22 after fixing the upper mold 25 with the fixing jig of the present embodiment. Further, it is also possible to insert and fix the upper mold 25 and the lower mold 22 in parallel. When the upper mold 25 and the lower mold 22 are inserted and fixed in parallel, the time required for mounting the molds is reduced, and work efficiency is improved.

In the case where the operations are performed in parallel, the upper mold 25 and the lower mold 22 are parallel to each other, and the fitting grooves 28 illustrated in FIG.
b and 21b are slid. Therefore, when performing the mounting method in which mounting is performed by adjusting the interval H according to the first embodiment, the upper mold 25 and the lower mold 22 slide directly above each other. Therefore, forgetting to place an object between the upper mold 25 and the lower mold 22 is avoided beforehand as in the first embodiment.

In addition, the inconvenience that the positioning pins 24 and 29 illustrated in FIG. 1 must be stored so as not to be lost when the press device is not used is the first embodiment.
Follow the structure of. On the other hand, the fixing jig F1 of the present embodiment is still attached to the lower stool 21, so that there is no trouble in storage.

Embodiment 5 FIG. 8 is a perspective view illustrating the structure of the press device according to the present embodiment. The press device shown in FIG. 13 is obtained by replacing the fixing jig F1 of the fourth embodiment illustrated in FIG. 7 with the fixing jig of the present embodiment, and has the same structure in other parts. I have. Less than,
Only the replaced part will be described.

The surface plate 21 is provided with two bearings 41 each having a shaft 42 rotatably inserted through a through hole. A pressing tool 43 is fixed to the shaft 42. Bearing 4
The fixing jig F2 of the present embodiment is configured by the shaft 42, the shaft 42, and the pressing tool 43.

First, as illustrated by a two-dot chain line in FIG. 8, the mold 22 is inserted into the groove 21b with the pressing tool 43 hanging down.
