Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for manufacturing punched metal having various hole shapes, and more particularly, to a non-hole pattern in which hole shapes are partially missing or an irregular pitch arrangement. The present invention relates to a manufacturing apparatus and a manufacturing method for manufacturing a punching metal having punched holes.

[0002]

2. Description of the Related Art Generally, a punching metal is a plate in which holes such as a circle, a corner, a star, and the like are punched out at equal pitches on the entire surface.
Processed into shapes and used for various products. Some of such punching metals are stamped on the entire surface, while others are stamped only on specific portions.

A conventional punching metal manufacturing apparatus for mass-producing punching metal includes a feeder or other material feeder that feeds a plate material such as a coil material in a direction parallel to the plate surface and feeds the material into a mold. A punch arranged to face the flat surface of the flat material supplied by the material feeding device and punching the flat material, a plate member such as a backing plate arranged on the base end side of the punch, and a material feeding device. Reciprocating drive means such as a press machine for reciprocating the plate member in a direction substantially perpendicular to the direction in which the plate material is supplied, and a die arranged opposite to the punch with respect to the plate material supplied by the above. Is provided.

[0004] Punches and dies are formed in one to several tens at predetermined pitches in the width direction of the supplied plate material, and in one to several rows in the supply direction of the plate material, punches of various shapes such as circles, corners, and stars. A die is provided, and the punch, die and backing plate are mounted in a mold. And the vertical movement of the mold by the reciprocating drive of the press machine and the material feeding timing of the plate material by the material supply device are linked, and the punching process is continuously performed on the plate material, so that holes are uniformly formed on the entire surface of the material. It is to be processed.

Further, as a manufacturing apparatus for manufacturing a punching metal having a non-hole pattern in which a hole shape is partially missing or punch holes arranged at an irregular pitch, a flat plate material serving as a material of the punching metal is supplied. And a press machine equipped with a die in which tens to hundreds of punches and dies are arranged on the entire surface in accordance with the hole shape of the product. Then, the flat plate material supplied by the material supply device is punched by moving the mold up and down by a press machine.

In this case, when the hole pitch of the product is narrow, all the holes cannot be formed at once, so that the mold is divided into a plurality of steps and the product is completed through several steps. is there.

[0007] In addition, when manufacturing a punching metal having a non-hole pattern in which a hole shape is partially missing or punch holes arranged at irregular pitches, a sheet material such as a fixed length material is formed by several punch dies. There is a method in which the hole is moved in the X and Y directions by an NC turret punching machine equipped with a hole punching method in synchronization with the movement, and a method in which the hole is chemically melted by photo etching or the like.

[0008]

However, in the conventional apparatus and method for manufacturing a punching metal having a non-hole pattern in which a hole shape is partially missing or punch holes arranged at an irregular pitch, the number of molds is small. Since a large number of tens to hundreds of punches and dies are arranged according to the hole shape of the product, high-precision mold processing for alignment of many punches and dies arranged in the mold is required. This is necessary, and there is a problem that the mold manufacturing cost increases. Further, maintenance is required for each punch die, and the cost required for the maintenance also increases. In the case of manufacturing a punching metal using an NC turret punch, in order to manufacture a punching metal having several hundreds to thousands of holes, it is necessary to align all the holes with the positions of several punches and dies. However, there is a problem in that a large amount of time is required for moving the material by the NC turret punch, and an expensive dedicated machine called an NC turret punch is required. Also,
The photo-etching method requires dozens of steps such as cleaning, resist, development, and etching, and also requires wastewater treatment equipment for environmental protection, which increases equipment costs and is chemical etching. The thickness is limited to a thin plate, and the etching time is long in this thin plate, so that there is a problem that the production cost increases. That is, any of the conventional techniques of punching only a necessary portion in large quantities is uneconomical.

[0009] Therefore, the present invention has been made in view of the above circumstances, and can be manufactured at low cost and economically when manufacturing a punching metal having a non-hole pattern in which a hole shape is partially missing. A technical object is to provide an apparatus and a manufacturing method.

[0010]

Means for Solving the Problems The invention of claim 1 made in order to solve the above technical problem is to provide a mold having an upper mold and a lower mold and a flat plate material in a direction parallel to the flat plate surface. A material supply device that intermittently moves and supplies a flat plate material into the mold, and a punch that is arranged to face the flat surface of the flat plate material supplied into the mold and punches the flat plate material. ,
A plate member disposed on the base end side of the punch and formed with a recess having a predetermined shape; reciprocating drive means for reciprocating the plate member in a direction substantially perpendicular to an intermittent movement direction of the plate material; And a moving means for intermittently moving the plate member in a direction parallel to the intermittent moving direction of the plate material in conjunction with the intermittent movement.

According to the above invention, when processing the flat plate material, the flat plate material is intermittently moved by the material supply device, and the plate member having the predetermined recess formed by the moving means is moved intermittently. Move in conjunction. When the base end of the punch faces a portion other than the concave portion of the plate member due to the intermittent movement of the plate member, the punch reciprocates with the plate member to punch a hole in the plate material. When the base end faces the concave portion of the plate member, the base end portion of the punch is inserted into the concave portion so that the flat plate material is not punched. Therefore, by adding a simple structure of a plate member having a desired concave portion formed thereon and a moving means for moving the plate member in conjunction with the intermittent movement of the plate material, punch holes can be formed or formed at desired positions. The punching metal having a non-hole pattern and unequal-pitch holes can be easily processed with an inexpensive configuration and can be made economical.

Here, the non-hole pattern is a non-hole pattern when a portion that has not been subjected to the punching processing has a specific shape. For example, as shown in FIG.
If it is a character, this A character is called a non-hole pattern.

According to another aspect of the present invention, in order to solve the above-mentioned technical problem, according to the first aspect of the present invention, the recess having a predetermined shape formed in the plate member is provided with a non-hole of a punching metal to be formed. It is preferable to provide a punching metal manufacturing apparatus characterized by having the same shape as the pattern.

According to the second aspect of the present invention, the recess having a predetermined shape formed in the plate member has the same shape as the non-hole pattern of the punching metal to be formed. What is necessary is just to form based on the non-hole pattern of a punching metal, and the workability | operativity at the time of forming such a recessed part improves, and since the shape securing is easy, the precision of the non-hole pattern formed improves. It is.

Preferably, according to the first or second aspect of the present invention, when the plate member reaches the vicinity of the reciprocating top dead center by the reciprocating drive means, the flat plate material and the movement of the plate member are set forth. Wherein the reciprocating drive means and the material supply means are linked so as to perform a punching metal manufacturing process.

According to the third aspect of the present invention, the reciprocating drive means and the material supply means are interlocked so that the reciprocating drive means performs intermittent movement of the plate member when the plate member reaches the vicinity of the reciprocating top dead center. In addition, the moving operation of the plate member is reliably performed, and the productivity and the maintenance of the equipment are improved. On the other hand, for example, when the plate member is moved near the bottom dead center of the reciprocating motion, the plate member moves in a state where the reciprocating load is applied from the reciprocating driving means, and a driving force greater than the reciprocating load is applied. Otherwise, the plate member cannot be moved, and the material supply means and the moving means may be broken due to overload. Also, in this case, the plate member moves while being pressed, which deteriorates the durability of the plate member itself. According to the present invention, such a problem can be solved.

More preferably, as in the fourth aspect of the present invention, in any one of the first to third aspects, the material supply device includes a single shaft having an arm that can intermittently move in a moving direction of the flat plate material. A punching metal manufacturing apparatus characterized by being a robot.

According to the fourth aspect of the present invention, as the material supply device, a single-axis robot having an arm capable of intermittently moving in the moving direction of the flat plate material is adopted, and the material is intermittently connected to the arm. Moving. By doing so, a punching metal can be manufactured with high precision. In addition, the amount of intermittent movement of the arm can be easily set to an arbitrary amount by a program, so it can flexibly respond to the shape of the recess formed in the plate member and product requirements, and has a wide variety of non-hole patterns It is possible to manufacture metal.

According to a fifth aspect of the present invention, a sheet material is intermittently moved in a direction parallel to a plane of a flat plate and supplied into a mold. A plate member provided on the base end side of a punch disposed opposite to a flat plate surface of a material and having a concave portion of a predetermined shape is reciprocated in a direction substantially perpendicular to a feeding direction of the flat plate material, and the flat plate material is reciprocated. When the intermittent movement intermittently moves in a direction parallel to the supply direction of the plate material, and the intermittent movement of the plate member causes the base end of the punch to face a portion other than the concave portion of the plate member, The punch reciprocates together with the plate member to perform a punching process on the plate material, and when the base end of the punch faces the recess of the plate member, the base end of the punch is inserted into the recess. Tehira A method for producing a punching metal, characterized in that so as not subjected to piercing the material.

According to the sixth aspect of the present invention, the plate member is intermittently moved in the direction parallel to the material supply direction during the processing, and the movement causes the base end of the punch to face a portion other than the concave portion of the plate member. In such a case, the punch reciprocates with the plate member to make a hole in the plate material, and when the base end of the punch faces the recess of the plate member by this movement, the base end of the punch is inserted into the recess. Thus, the punching process is not performed on the flat plate material. Therefore, by adopting a simple method of intermittently moving the plate member in which the desired concave portion is formed in conjunction with the intermittent movement of the plate material, forming or not forming a punch hole at a desired position. This makes it possible to easily process a punching metal having a non-hole pattern with an inexpensive configuration and to be economical.

Reference numeral 17 denotes an ejector which is fixed on the upper surface of the die holder 15 by a spring or the like so as to move up and down, floats a punched plate material slightly from the die surface, and facilitates the feeding movement.

The upper die base 4 is mechanically connected to a reciprocating drive mechanism 18. The reciprocating drive mechanism 18 applies a reciprocating driving force in the vertical direction in the figure to the upper die base 4, and thereby the upper plate 5 and the backing plate 10 connected to the upper die base 4.
Also, the reciprocating drive mechanism 18 is driven to reciprocate integrally with the upper die base 4 in a direction perpendicular to the material supply direction of the flat plate material, which is the vertical direction in the drawing.

As shown in FIGS. 1, 3 and 4, the flat plate material E is held on a material holding plate 19 at its side end. The material holding plate 19 includes an upper plate 19a and a lower plate 19b, and a pilot pin 19c held on the upper plate 19a is inserted into a pilot hole 25c (see FIG. The material E is held. A base end of a tuning pin 20 is connected to the material holding plate 19, and a tip end of the tuning pin 20 is connected to a bush 10 c formed on the backing plate 10.
It is inserted inside. Therefore, the tuning pin 20 corresponds to a moving means for intermittently moving the backing plate 10 in conjunction with intermittent movement of the flat plate material E held on the material holding plate 19, which will be described later.

As shown in FIG. 1 and FIG. 4, a single-axis robot 21 is connected to the material holding plate 19. The single-axis robot 21 includes an arm 21a and a support 21b connected to a base of the arm 21a, and the arm 21a and the support 21b extend along the guide rail 22.

Therefore, when the arm 21a intermittently moves due to the driving of the single-axis robot 21, the material holding plate 19 connected to the arm 21a and the flat plate material E held by the material holding plate 19 intermittently move. Accordingly, the single-axis robot 21 corresponds to a material supply device that supplies the flat plate material E into the mold 1 by intermittently moving the flat plate material E in a direction parallel to the flat plate surface. The intermittent movement of the single-axis robot 21 can be arbitrarily set by a program.

FIG. 6 is a view showing the backing plate 10, and FIG. 6 (a) is a view showing a lower surface side of the backing plate 10 shown in FIG. FIG. 6B is a diagram showing the FF in FIG.
It is sectional drawing. As shown in the figure, the backing plate 1
In 0, a concave portion 10a of a predetermined shape and a flat portion 10b other than the concave portion 10a are formed. In this example, the recess 10a is formed in the same shape as the non-hole pattern to be formed in the punched metal. That is, when a punching metal 25 having a circular punch hole forming portion 25a in the center shown in FIG.
Has a circular flat portion 10b formed in the center and a concave portion 10a formed in other portions. That is, the flat portion 10b of the backing plate 10 corresponds to the punch hole forming portion 25a of the punching metal 25, and the concave portion 10a of the backing plate 10 corresponds to the non-hole pattern portion 25b other than the punch hole forming portion 25a of the punching metal 25. Is supported.

In the present embodiment, the punch 14 is
As shown in the figure, it is composed of two rows, and plural (7, 8) for each row
The ones that are lined up are used. In this case, as shown in FIG.
Reference numeral 4 denotes an arrangement as shown.

The operation of the above construction will be described below. First, the flat plate material E is held on the material holding plate 19 in the mold open state. Next, the single-axis robot 21 is driven, and the plate material E is intermittently supplied into the mold 1 by repeatedly moving and stopping the same, and the reciprocating drive mechanism 18 is driven. The reciprocating drive mechanism 18 is moved in accordance with the timing at which the flat plate material E moves to a predetermined position and the moving operation stops.
The upper die base 4 moves downward in FIG. Therefore, the punch holder 5 fixed to the upper die base 4, the backing plate 10 disposed between the upper die base 4 and the punch holder 5, the stripper 13 connected to the punch holder 5 by the connecting member 12,
Punch 1 inserted in stepped through holes 11a and 13a
4 are integrally moved in the downward direction shown in FIG. 2 while being guided by the guide posts 9.

Immediately before the bottom dead center of the downward movement by the reciprocating drive mechanism 18, the leading end surface of the punch 14 protruding from the lower surface of the stripper 13 abuts on the flat surface of the flat material E supplied by the single-axis robot 21. A schematic diagram of this state is shown in FIG.
And FIG. In this case, when the base end portion 14a of the punch 14 and the flat portion 10b of the backing plate 10 where the concave portion 10a is not formed face each other as shown in FIG. Flat plate material E
Receives the punching load from the reciprocating drive mechanism 18 via the flat portion 10b of the backing plate 10, and when the punching load exceeds a certain value, the plate material E is punched. On the other hand, in this case, as shown in FIG.
0a is facing the backing plate 10
As the reciprocating operation proceeds, the base end portion 14a is inserted into the concave portion 10a. Therefore, the reciprocating drive mechanism 1
No punching load from 8 is applied. That is, when viewed from the plate material E, the punch 14 operates so as to be retracted into the concave portion 10a with respect to the plate material E. Therefore, punch 1
4 stops the punching of the plate material E.

In the above-described punching process, the driving of the single-axis robot 21 is stopped, and accordingly, the plate material E and the backing plate 10 are stopped. Then, the reciprocating drive mechanism 1
When the punch 14 moves upward in the figure by 8 and reaches near the reciprocating top dead center, the stopped single-axis robot 21 is driven. Then, the arm 21a of the single-axis robot 21
And the flat plate material E held by the material holding plate 19 is moved. Since the material holding plate 19 is also connected to the backing plate 10 by the tuning pin 20, the backing plate 10 moves in conjunction with the movement of the flat plate material E.
In this case, the movement of the backing plate 10 is intermittently performed by the tuning pin 20 in conjunction with the intermittent movement of the plate material E. The movement is linked so that the movement timing and the movement distance are the same.
Then, when the plate material E moves by a predetermined amount and reaches the set position, the driving of the single-axis robot 21 is stopped again. Therefore, the movement of the flat plate material E and the backing plate 10 is also stopped. The reciprocating driving force in the vertical direction shown in FIG. 2 is applied to the upper die base 4 by driving the reciprocating drive mechanism 18 in accordance with the timing at which the movement of the flat plate material E and the backing plate 10 is stopped, and punching is performed.

By repeating the above operation, it is possible to manufacture a punching metal having a non-hole pattern or punch holes arranged at irregular pitches.

As described above, the base end portion 14a of the punch 14 is flattened except the concave portion 10a of the backing plate 10.
When the sheet material E is opposed to the sheet material b (see FIG. 7), the punching load of the reciprocating drive mechanism 18 is transmitted from the punch 14 to the flat plate material E, and the flat plate material E is punched by the punch 14 to perform punching.
If the base end 14a of the punch 14 faces the recess 10a of the backing plate 10 (see FIG. 8), the punch 1
4 prevents the punching load from the reciprocating drive mechanism 18 from being transmitted to the plate material E by inserting the base end portion 14a into the concave portion 10a. No punching is performed. Then, the backing plate 10 is intermittently moved in conjunction with the movement of the flat plate material E intermittently moved by the single-axis robot 21, and the positional relationship between the base end 14a of the punch 14 and the backing plate 10 is variously changed. Punch holes are formed in predetermined portions of the flat plate material E and punch holes are not formed in predetermined portions, that is, a desired non-hole pattern can be formed. In particular, in this example, the backing plate 10 has a circular flat portion 10b and other concave portions 10b.
a, the backing plate 10 is sequentially intermittently moved in conjunction with the intermittent supply of the plate material E by the single-axis robot 21.
A punching metal 25 having a circular punched hole 25a and a non-hole pattern 25b as shown in FIG.
Can be manufactured.

When the backing plate 10 is moved and the forming of one punched metal is completed, the upper and lower cylinders 30 (see FIG. 1) are raised to lift the plate material E. For this reason, the pilot hole 25 c formed in the flat plate material E is
Removed from upward. Then, only the backing plate 10 and the material holding plate 19 are returned to the origin by the single-axis robot 21. Thereafter, the above operation is repeated again, thereby continuously forming the punched metal.

As described above, in this embodiment, the single-axis robot 21 intermittently moves the plate material E in a direction parallel to the flat plate surface and supplies the same into the mold 1. 1. A punch 14 arranged opposite to the flat surface of the flat plate material E supplied into the flat plate 1 for punching the flat plate material E, and a concave portion 1 arranged on the base end 14a side of the punch 14 and having a predetermined shape.
Backing plate 10 on which the backing plate 10a is formed, a reciprocating drive mechanism 18 for reciprocating the backing plate 10 in a direction perpendicular to the material supply direction of the flat plate material E (arrow F in FIG. 2), and a flat plate by a single-axis robot 21. A punching metal manufacturing apparatus 100 includes a tuning pin 20 as a moving means for intermittently moving the backing plate 10 in a direction parallel to the material supply direction of the flat plate material E in conjunction with the intermittent movement of the material E. Then, by adding a simple configuration of the backing plate 10 having the desired concave portion 10a formed thereon and the tuning pin 20 for moving the backing plate 10 in conjunction with the intermittent movement of the flat plate material E, the punch hole is formed at a desired position. Can be formed or not formed, and equipment and manufacturing costs are reduced as compared with the conventional apparatus. Can be to the valence, it is capable to economical.

Further, the material holding plate 19 and the backing plate 10 connected to the single-axis robot 21 are connected by the tuning pin 20, and the intermittent movement timing and movement amount of the backing plate 10 and the intermittent movement timing and movement of the flat plate material E are controlled. Since the amount is linked to be the same,
A hole pattern and a non-hole pattern can be reliably formed at a target position, and the quality of a product is improved.

Since the concave portion 10a of the predetermined shape formed on the backing plate 10 has the same shape as the non-hole pattern of the punching metal to be formed, the concave portion 10a of the punching metal is What is necessary is just to form based on a non-hole pattern, and workability | operativity at the time of forming such a recessed part improves.

In this embodiment, the backing plate 10 intermittently moves in conjunction with the single-axis robot 21 when the backing plate 10 reaches the vicinity of the top dead center by the reciprocating drive mechanism 18. On the other hand, for example, when the backing plate 10 is moved near the reciprocating bottom dead center, the backing plate 10 is moved with a punching load applied thereto, and the driving force of the single-axis robot 21 is greater than the punching load. If the backing plate 10 is not provided, the backing plate 10 cannot be moved, and the backing plate 10 moves while being pressed, thereby deteriorating the durability. In this example, such a problem can be solved.

In the above embodiment, an example is shown in which a punching metal 25 having a circular punch hole forming portion 25a and other non-hole pattern portions 25b as shown in FIG. 5 is formed. In addition, as shown in FIG. 9, the punching metal 30 can be formed with the non-hole pattern portion 30 b having the A-letter shape and the other punch hole forming portion 30 a. In this case, the recess formed in the backing plate 10 is a groove having the same shape as the non-hole pattern portion 30b having the A-letter shape. This shape groove may be a through groove or a bottomed groove. Further, as shown in FIG. 10, a dense portion 40a in which the punch holes are dense and a sparse portion 40 in which the punch holes are sparse.
The punching metal 40 having the unequal-pitch punched holes having “b” can also be formed. In this case, the recess formed in the backing plate 10 is formed by a round hole or a groove in a region indicated by a dotted line in the drawing, that is, a position where a punch hole is to be cut off in the sparse portion 40b of FIG.

The present invention is not limited to the above-described embodiment, but can be applied in various ways without departing from the gist of the present invention. For example, in the present embodiment, the configuration in which the intermittent movement between the backing plate 10 and the flat plate material is linked by the tuning pin 20 has been described, but the flat plate material E is moved by a roll feeder or the like, and the backing plate is moved by a single-axis robot or the like. May be configured to be moved by the moving mechanism described above and to be linked by a control device or the like. In this case, the material supply device is a roll feeder, and the moving means is a single-axis robot and a control device.

[Claims] A mold provided with an upper mold and a lower mold; a material supply device for intermittently moving the plate material in a direction parallel to the plane of the plate to supply the plate material into the mold; A punch that is disposed opposite to the flat surface of the flat material supplied into the flat material and performs punching on the flat material, a plate member that is disposed on a base end side of the punch and has a recess having a predetermined shape, Reciprocating drive means for reciprocating the plate member in a direction substantially perpendicular to the intermittent movement direction of the plate material; and intermittently moving the plate member in a direction parallel to the intermittent movement direction of the plate material in conjunction with the intermittent movement of the plate material. And a moving means for moving. 2. The punching metal manufacturing apparatus according to claim 1, wherein the recess having a predetermined shape formed in the plate member has the same shape as a non-hole pattern of the punching metal to be formed. 3. The reciprocating drive means and the material according to claim 1, wherein the plate material and the plate member are moved when the reciprocating drive means moves the plate member near a reciprocating top dead center. An apparatus for manufacturing punched metal, wherein the apparatus is linked with a supply unit. 4. The punching metal sheet according to claim 1, wherein the material supply device is a single-axis robot having an arm that can intermittently move in a moving direction of the plate material. manufacturing device. 5. A flat plate material is intermittently moved in a direction parallel to the flat plate surface and is supplied into a mold. The punch material is disposed on a base end side of a punch disposed opposite to the flat plate surface of the supplied flat plate material. The plate member provided with the concave portion having a predetermined shape is reciprocated in a direction substantially perpendicular to the supply direction of the plate material, and intermittently moves in a direction parallel to the supply direction of the plate material in conjunction with the intermittent movement of the plate material. When the base end portion of the punch faces a portion other than the concave portion of the plate member due to the intermittent movement of the plate member, the punch reciprocates with the plate member to perform a punching process on the plate material, When the base end of the punch faces the concave portion of the plate member, the base end of the punch is inserted into the concave portion so that the punching processing is not performed on the flat plate material. Manufacturing method.
