Furthermore, hereinafter, in the Z-axis direction, the upper side in FIG. 1 is simply referred to as the upper side, and in the Z-axis direction, the lower side in FIG. 1 is simply referred to as the lower side. In addition, the Z-axis direction is also simply referred to as a vertical direction, the X-axis direction is also simply referred to as a left-right direction, and the Y-axis direction is also simply referred to as a front-back direction. A direction along a plane parallel to the X axis and the Y axis is also simply referred to as a horizontal direction or a lateral direction. 2 to 4, the X axis, the Y axis, and the Z axis are similarly illustrated.

The die 11 for press working is mounted on a press working apparatus, and is made of iron material such as steel plate, steel material or special steel, non-ferrous metal material such as aluminum, copper, titanium or magnesium or non-ferrous metal material such as alloy thereof, plastic material or composite material. Press processing of non-metal materials such as. The press working apparatus may be equipped with a crank drive mechanism, a knuckle drive mechanism, or a link mechanism, or may be a mechanical press system or a hydraulic press system which is a servo press. That is, the press working apparatus can be provided with the press working die 11. The press working apparatus applies a working force to the die 11 for press working to press the metal material.

The die 11 for press working includes shearing (including cutting and cutting), punching (including blanking), trimming, bending, flange forming, drawing, forming, compression or joining. Used for press processing such as processing. Hereinafter, description will be made by taking the press-molding die 11 used for punching as an example.

The press mold 11 shown in FIG. 1 includes an upper mold 21 and a lower mold 22. The upper die 21 and the lower die 22 are so-called die-equipped dies. The upper die 21 is attached to the slide of the press working device, and when performing the press working, it is displaced in the Z-axis direction (vertical direction) by the press working device, and the material is sandwiched between the lower die 22 and pressed to work. To do. The lower die 22 is attached to a bolster plate of a press working device, and its position is fixed during press working. The lower die 22 includes a die 31, a die plate 32, and a die holder 33.

The upper die 21 includes a punch 51, a vibrator 52, support members 53-1 and 53-2, a punch plate 54, a punch plate 55, a spacer 56, a punch holder 57, a stripper 58, and a guide pin 59.

First, the configuration of each part of the upper mold 21 will be described. The punch 51 is displaced downward by the processing force of the press processing device and pressed against the material to transfer the shape to the material. In the punching process, the punch 51 is pressed against the material and punches the material into a desired shape.

The vibrator 52 applies a vibration whose amplitude direction is the Z-axis direction to the punch 51. The vibrator 52 is a so-called vibrating device, and is a semiconductor such as a piezoelectric element, an electric motor in which an eccentric weight is attached to a rotating shaft, a solenoid that linearly displaces the weight, or a linear displacement of the weight. It consists of an air tool (air vibrator). The frequency of the vibration generated by the vibrator 52 can be set to 20 Hz to 40 kHz corresponding to the audible band of sound or the band of ultrasonic waves. The frequency of the vibration generated by the vibrator 52 is determined by the speed of vertical displacement of the punch 51, the type of material, the shape and size of the formed material, and the like. The amplitude of the vibration generated by the vibrator 52 is determined by the vertical displacement speed of the punch 51, the type of material, the shape and size of the material to be formed, and the like. For example, the frequency of the vibration generated by the vibrator 52 is such that the speed of displacement due to the vibration in the amplitude direction (the speed of deformation of the punch 51 (particularly the speed of deformation of the processing end 101 described later)) is in the vertical direction of the punch 51. It is decided to be faster than the speed of displacement.

The support member 53-1 is formed in a rectangular column shape. The support member 53-1 is a so-called key that is engaged with the punch 51, the punch plate 54, and the punch plate 55 to fix the punch 51, the punch plate 54, and the punch plate 55. The right side of the support member 53-1 is fitted in a recess formed on the left side surface of the punch 51 and fixed in the X axis direction and the Z axis direction. Details of the recess formed on the left side surface of the punch 51 will be described later. The left side of the support member 53-1 is sandwiched by the punch plate 54 and the punch plate 55 and fixed in the X axis direction and the Z axis direction.

The support member 53-2 is formed in a rectangular column shape. The support member 53-2 is a so-called key that is engaged with the punch 51, the punch plate 54, and the punch plate 55 to fix the punch 51, the punch plate 54, and the punch plate 55. The left side of the support member 53-2 is fitted into a recess formed on the right side surface of the punch 51 and fixed in the X axis direction and the Z axis direction. Details of the concave portion formed on the right side surface of the punch 51 will be described later. The right side of the support member 53-2 is sandwiched by the punch plate 54 and the punch plate 55 and fixed in the X axis direction and the Z axis direction.

In this way, the support members 53-1 and 53-2 are formed in the shapes corresponding to the recesses formed on the side surfaces of the punch 51, respectively, and are fitted into the recesses, respectively, and the punch plate 54 and the punch plate 55 are interposed therebetween. The force in the Z-axis direction is transmitted to the punch 51.

The punch plate 54 and the punch plate 55 position the punch 51 through the sandwiching support members 53-1 and 53-2, and fix the punch 51. The punch plate 54 and the punch plate 55 are fixed to the spacer 56 with bolts 71.

The punch plate 54 and the punch plate 55 maintain the positional relationship between the punch 51 and the stripper 58. Further, the punch plate 54 positions the guide pin 59 and fixes the guide pin 59. The stripper 58 removes the material attached to the punch 51. The stripper 58 is held by bolts 73 through which a spring 60, which is a coil spring, passes, and bolts 73 that pass through the holes of the punch plate 54, the punch plate 55, and the spacer 56, respectively. The stripper 58 is displaced upward with respect to the punch 51 against the biasing force of the spring 60 when the punch 51 pulls out the material. When the punch 51 is displaced to the upper side after removing the material, the stripper 58 is displaced to the lower side with respect to the punch 51 by the urging force of the spring 60, and thereby the material attached to the punch 51 is discharged. On the lower surface of the stripper 58, a recess 81 is formed which is recessed upward so that the material attached to the punch 51 can be easily wiped off. When the punch 51 is displaced downward, the guide pin 59 enters the hole of the die 31 to maintain the positional relationship between the punch 51 and the die 31.

The spacer 56 holds the positions of the punch 51 and the punch holder 57. The punch holder 57 is fixed to the spacer 56 by a bolt 72 screwed to the spacer 56. The punch holder 57 holds the entire upper die 21, that is, the punch 51, the vibrator 52, the support members 53-1 and 53-2, the punch plate 54, the punch plate 55, the spacer 56, the stripper 58, and the guide pin 59. The punch holder 57 is attached to the slide of the press working device with a bolt or the like (not shown).

The punch plate 54, the punch plate 55, and the stripper 58 do not directly contact the punch 51.

Next, the lower mold 22 will be described.

The die 31 is a tool on the receiving side of the punch 51, and sandwiches the material with the punch 51 pressed by the processing force of the press working device, and transfers the shape to the material. In the punching process, the die 31 sandwiches the material with the punch 51 pressed by the working force of the press working device, and punches the material into a desired shape.

The die plate 32 is sandwiched and fixed by the die 31 and the die holder 33, and holds the position of the die 31 with respect to the die holder 33. The die holder 33 holds the die plate 32 and the die 31. Bolts 41-1 to 41-4 (bolts 41-3 and 41-4 are not shown) which are passed through the holes of the die 31 and the holes of the die plate 32 are screwed into the die holder 33. The bolts 41-1 to 41-4 fix the die 31, the die plate 32, and the die holder 33 to each other.

The die holder 33 is attached to the bolster plate of the press working device with a bolt or the like (not shown).

Next, the configuration of the punch 51 will be described in detail with reference to FIGS. 2 to 4. FIG. 2 is a perspective view showing the shape of the punch 51. FIG. 3 is a front view showing the front shape of the punch 51. FIG. 4 is a top view showing the shape of the upper surface of the punch 51.

In FIG. 3, the dashed line AA′ indicates the center of the front surface of the punch 51 in the X-axis direction (horizontal direction), and the dashed line BB′ indicates the upper surface of the punch 51 in the Z-axis direction (vertical direction). ) Indicates the center. In addition, in FIG. 4, a CC′ line indicated by a one-dot chain line indicates a center in the X-axis direction (horizontal direction) on the upper surface of the punch 51, and a DD′ line indicated by a one-dot chain line indicates a Y-axis direction on the upper surface of the punch 51 ( (Front-back direction) indicates the center.

The punch 51 is formed in a vertically long, generally rectangular parallelepiped shape in which a recessed portion is provided in the central portion of the side surface. The punch 51 has a bilaterally symmetrical shape. That is, the punch 51 is formed in a line-symmetrical shape with respect to the YZ plane passing through the center in the X-axis direction (horizontal direction). Alternatively, the punch 51 is formed in a vertically symmetrical outer shape. That is, the punch 51 is formed in an outer shape that is line-symmetric with respect to the XY plane that passes through the center in the Z-axis direction (vertical direction).

The lower end of the punch 51 is formed as a processing end 101. When the press working is performed, the working end 101 presses the material to be pressed in the downward direction. The processing end 101 has a shape corresponding to the shape desired to be obtained by press working. For example, in the case of punching, the processing end 101 is pressed against the material and the shape is transferred to the material, so that the material is punched into a desired shape. For example, the processed end 101 is formed in a square shape when it is desired to remove a square plate material.

The upper end of the punch 51 is formed as a vibrating end 102. The vibrator 52 is fixed to the vibrating end 102 and vibration is applied. The vibrating portion 121 is formed as a screw hole at the center of the vibrating end 102 in the X-axis direction (horizontal direction) and the Y-axis direction (front-back direction). The vibrator 52 is attached to the vibration unit 121. The vibrator 52 is screwed into the vibrating section 121 and is attached to the center of the vibrating section 121 in the X-axis direction (horizontal direction) and the Y-axis direction (front-rear direction). Vibration is applied to the center of the (left-right direction) and the Y-axis direction (front-back direction).

A recess 105-1 is provided in the center of the left side surface of the punch 51. A recess 105-2 is provided at the center of the right side surface of the punch 51. The recess 105-1 and the recess 105-2 are provided so as to face each other with a predetermined distance apart in the X-axis direction (horizontal direction). The position in the Z-axis direction (vertical direction) where the recess 105-1 is formed is the same as the position in the Z-axis direction (vertical direction) where the recess 105-2 is formed.

The recess 105-1 is formed in a shape in which a predetermined gap is created when the support member 53-1 is fitted. More specifically, when the right side of the support member 53-1 is fitted in the recess 105-1, the gap between the recess 105-1 and the support member 53-1 fitted in the recess 105-1 is the Z-axis direction (vertical direction). ) Is formed in a shape corresponding to the shape on the right side of the support member 53-1 so that the distance of () is equal to or larger than the amplitude of the vibration applied by the vibrator 52. For example, the distance between the recess 105-1 and the support member 53-1 fitted in the recess 105-1 in the Z-axis direction (vertical direction) is 100 μm to 5 μm. As an example, the distance between the recess 105-1 and the support member 53-1 fitted in the recess 105-1 in the Z-axis direction (vertical direction) is 20 μm.

Similarly, the recess 105-2 is formed in a shape in which a predetermined gap is created when the support member 53-2 is fitted. More specifically, when the left side of the support member 53-2 is fitted in the recess 105-2, the gap between the recess 105-2 and the support member 53-2 fitted in the recess 105-2 is in the Z-axis direction (vertical direction). ) Is formed in a shape corresponding to the shape on the left side of the support member 53-2 so that the distance of () is equal to or larger than the amplitude of the vibration applied by the vibrator 52. For example, the distance between the recess 105-2 and the support member 53-2 fitted in the recess 105-2 in the Z-axis direction (vertical direction) is 100 μm to 5 μm. As an example, the distance between the recess 105-2 and the support member 53-2 fitted in the recess 105-2 in the Z-axis direction (vertical direction) is 20 μm.

The shape of the recess 105-1 and the shape of the recess 105-2 are the same.

By doing so, the direction of the vibration transmitted through the punch 51 does not change, the vibration applied to the vibrating end 102 is directly transmitted to the processing end 101, and the vibration applied to the vibrating end 102 is further attenuated. The vibration is reduced, and the vibration applied to the vibrating end 102 is efficiently transmitted to the processing end 101.

The recess 105-1 and the recess 105-1 are formed so that the gap generated when the support member 53-1 is fitted in the recess 105-1 is the same as the gap generated when the support member 53-2 is fitted in the recess 105-2. The recess 105-2, the supporting member 53-1 and the supporting member 53-2 are formed.

The shape of the recess 105-1 and the shape of the recess 105-2 are formed line-symmetrically with respect to the center in the X-axis direction (horizontal direction) indicated by the line AA'. Each of the recess 105-1 and the recess 105-2 is formed in a linear groove shape whose longitudinal direction is the Y-axis direction (front-back direction).

The recesses 105-1 and 105-2 can be formed in desired shapes as long as they can hold the punch 51. For example, the recess 105-1 and the recess 105-2 can be formed in a hollow having a cylindrical shape or a quadrangular prism shape. Further, for example, the recess 105-1 and the recess 105-2 can be formed in a semicircular shape or a triangular shape on a plane defined by the Z axis and the X axis, or defined by the Z axis and the Y axis. It can also be formed in a circular shape, an oval shape, or an elliptical shape in a plane.

The shapes of the recess 105-1 and the recess 105-2 can be determined relatively freely. When the recess 105-1 and the recess 105-2 are deep (largely carved in the X-axis direction), vibrations are gathered in the portion between the recess 105-1 and the recess 105-2, but resistance to the vibration increases. The processing force of the press processing device can be more efficiently transmitted to the punch 51. In this case, by lowering the heights of the recesses 105-1 and 105-2 in the Z-axis direction, it is possible to further reduce resistance to vibration.

If the recessed portion 105-1 and the recessed portion 105-2 are shallow (which is small in the X-axis direction), resistance to vibration can be further reduced. In this case, by increasing the height of the recess 105-1 and the recess 105-2 in the Z-axis direction, the processing force of the press working device can be more effectively transmitted to the punch 51.

A notch 103 that is long in the Z-axis direction (vertical direction) is formed in the center of the front surface of the punch 51. As shown in FIG. 3, the notch 103 is formed along the center of the front surface of the punch 51 in the X-axis direction (horizontal direction). The cut 103 is a flat surface cut. The notch 103 penetrates the front surface and the back surface of the punch 51. That is, the cut 103 penetrates the opposing side surfaces of the punch 51.

The center position of the notch 103 in the length direction coincides with the center position of the punch 51 in the Z-axis direction (vertical direction). A hole 104 is formed at the center of the punch 51 in the Z-axis direction (vertical direction) so as to penetrate the front and back surfaces of the punch 51. The length of the cut 103 in the Z-axis direction (vertical direction) is shorter than the length of the punch 51 in the Z-axis direction (vertical direction). The upper end of the notch 103 does not reach the processing end 101. The lower end of the notch 103 does not reach the vibrating end 102.

The notch 103 is sandwiched between the recess 105-1 and the recess 105-2 such that the respective distances from the recess 105-1 and the recess 105-2 are the same.

The width (length in the X-axis direction) of the cut 103 can be set to 5 mm to 0.1 mm. As an example, the width of the notch 103 (length in the X-axis direction) can be set to 0.5 mm.

When the punch 51 is vibrated by providing the notch 103, the notch 103 moves to the left and right, so that the vibration is collected in the notch 103 in the portion sandwiched by the recess 105-1 and the recess 105-2, and the recess 105-1 is formed. Also, the vibration is easily transmitted in the portion sandwiched by the recesses 105-2. In this way, the vibration applied to the vibrating end 102 can be guided so as to be transmitted toward the machining end 101, and the vibration applied to the vibrating end 102 is efficiently transmitted to the machining end 101. Further, by making the width (length in the X-axis direction) of the notch 103 narrower, the volume ratio of the notch 103 to the entire punch 51 becomes smaller, whereby the vibration applied to the vibrating end 102 is damped. The vibration applied to the vibrating end 102 is reduced, and the vibration is efficiently transmitted to the working end 101.

As described above, the punch 51 is a flat virtual surface extending from the processing end 101 to the vibration end 102, and has a virtual surface at the same distance from each of the recess 105-1 and the recess 105-2. It is formed in a symmetrical shape by sandwiching it. The punch 51 is a flat virtual surface that is orthogonal to the vertical direction that is the direction of displacement during press working, and is a virtual position at a position where the distance from the working end 101 and the distance from the vibrating end 102 are equal. It is formed in a symmetrical outer shape across the plane.

As described above, the upper die 21 includes the punch 51, the vibrator 52, and the support members 53-1 and 53-2. The punch 51 is formed with a processing end 101, a vibrating end 102, and recesses 105-1 and 105-2.

The vibrator 52 is attached to the vibrating end 102 and applies vibration to the vibrating end 102. The support members 53-1 and 53-2 are formed in the shapes corresponding to the recess 105-1 and the recess 105-2, respectively, and are fitted into the recess 105-1 and the recess 105-2, respectively, and are formed on the punch 51 in the Z-axis direction. Transmit the power of.

The processing end 101 is an end on the side that presses the material to be pressed in the Z-axis direction when performing press processing. The vibrating end 102 is an end portion facing the processing end 101, and is an end portion to which the vibrator 52 is fixed and vibration is applied. The recess 105-1 and the recess 105-2 have the same shape and face the side surface, which is the surface between the processing end 101 and the excitation end 102, at a predetermined distance in the X-axis direction orthogonal to the Z-axis direction. It is provided to do.
