There is known a turret-type multi-purpose cutting device for performing a cutting operation.

[0007] However, such a multipurpose cutting apparatus is complicated and expensive, and furthermore, when changing the cutting tool to be used, the work must be interrupted and the turret must be rotated to change the cutting tool. There was the inconvenience of having to do it.

On the other hand, during the blanking manufacturing process, the planar shape of the target paper mold is designed by CAD.
Also, regarding the processing of the board, it has been proposed to use a laser processing machine to machine the groove for the blade of the board based on the design data created by the CAD, and the accuracy and automation have already been considerable. Has reached a high standard.

[0009] However, in the field of manufacturing a cutter to be inserted into a groove for cutting blade of a board manufactured by an automatic system such as laser processing, automation is still slow and depends on a manual operation of a skilled worker. doing. Conventionally, various systems have been proposed for automating a cutting operation. However, a cutter material cutting apparatus capable of automatically performing various cuttings with a single facility has not yet been put to practical use.

The bending process can be performed using an inexpensive and small bending machine.

Next, FIG. 22 will be described. FIG.
Among them, 50 is a CAD for designing a product type to be punched, that is, a CAD for designing a shape of a cutter, 51 is a laser processing device for processing a groove for a cutting blade of a board into which a cutter is to be implanted, and a die 20; That is, an interface for inputting the CAD data to the central control device 500 of the present invention device, 53 is a memory for recording physical property data required for bending the cutter material, and the cutter cutting device according to the present invention It can be linked to these devices.

As described above, the central control unit 500 takes in the design data of the CAD 50 via the data conversion unit 52, reads out necessary data from the physical property data memory 53, and performs necessary calculations. Thus, the cutting press device 100, the cutting tool selection device 200, and the cutter material supply device 400 are controlled to perform necessary cutting work of the cutter material.

Next, the operation of the cutter for a punching die according to the present invention will be described. First, the cutting shape to be applied to the cutter material 40, that is, the cutter type and its cutting position are determined. In the case of the embodiment shown in FIGS. 22 and 23, a cutting tool 101 for linear cutting, a cutting tool 102 for linear cutting with a lip, a cutting tool 103 for bridge processing, and a cutting tool for notch cutting processing indicating a bending position.

The central control unit 500 includes a data conversion unit 52
The type of the cutting tool to be used is sequentially determined based on the data input from the computer, and the data of the cutting tool is temporarily recorded together with the position data to be cut by the cutting tool.

When manufacturing the cutter shown in FIG. 23, cutting is performed as shown in A, D, C and B in FIG. First, the first cutting is the cutting A of the end which is performed using the cutting tool 102 for linear cutting with a lip.

The central controller 500 controls the cutter material 40
Considering the relative position of the cutting tool 102 with respect to the traveling direction of the cutter material, the cutter material processing feed amount is calculated such that the cutting position of the cutter material 40 is just below the cutting tool 102 to be used. The central control unit 500 transmits a control signal for appropriately driving the drive motor of the metering roller 27 of the cutter material supply device 400 based on the calculation result, and the predetermined cutting position is used for the cutting tool 10 to be used.
Then, the cutter material 40 is processed and fed so as to be located immediately below the position 2.

Next, the central control device 500 sends a command signal to the cutting tool selection device 200, switches the switching valve of the air cylinder 122 corresponding to the cutting tool 102 to be used, and supplies compressed air to the corresponding air cylinder 102. I do. At that time, the transmitter 15 connected to the push rod 16 of the selected air cylinder 102 moves just below the tip 8 of the driving rod 6.

Next, the central control device 500 switches the switching valve of the driving air cylinder 1 of the cutting press device to lower the driving rod 6. In such a case, the tip 8 of the lower end of the driving rod 6 pushes down the cutting tool 102 thereunder via the transmitter 15 selected as described above, so that the cutting edge of the cutting tool 102 is Is cut into the groove provided in the die 20.

The cutter material 40 having completed the first cutting operation is sent downward by the metering roller 27 for the second cutting as described above, and the desired second cutting operation is performed at a predetermined position. Will be applied. At this time, there is no problem because the section from S to a in the figure is a straight line,
~ C is bent in an arc shape with a radius of 10 mm in the subsequent bending step, so that the distance between the end point a of the straight section and the point b where the marking should be performed is the length of the arc shown in FIG. The distance is not half of the length of 15.7 mm but half of the length of the arc minus half of the compensation amount α1 of the elongation due to bending.

This compensation amount α1 is stored in the physical property data memory 53.
Is immediately calculated from the physical property data of the cutter material read from the above, the radius of curvature of the bending process, and the length of the arc. The central controller 500 automatically calculates the compensation amount and corrects the processing feed amount, so that when the cut cutter material is later bent, a cutter that fits into the groove of the board can be obtained. . By repeating such a process, various cutting processes as shown in the figure are continuously performed.

The cutting process starts from the point S and continuously proceeds from the point a to the point j. A, B, C and D denote a linear cutting tool 102 with a lip, a linear cutting tool 101, a cutting tool 103 for bridge processing and The cutting process by the cutting tool 104 for notch cutting process showing the bending position is shown.

For example, in the above-described embodiment, a single press device is used for pressurizing the cutting tool, and the cutting tool selection is performed. As a means, it has been described that the cutting work is performed by selectively switching and driving a cutting tool selection air cylinder attached to each cutting tool to be used, but this involves attaching an independent press device to each cutting tool, and It is also possible to perform the desired cutting work by selectively switching the press device of the above, and also use an air cylinder attached to each cutting tool as cutting tool selection means, but this is mechanically Lever type or link type device that is controlled, or a solenoid device that can be electronically controlled may be used.In addition, the driving device for the press is not limited to the air cylinder, It can be replaced by a manual lever or replaced by other known actuators, and the present invention covers these modifications and all the modifications that can be easily conceived from the above description. is there.
