[0002]

2. Description of the Related Art In a case where a plurality of blanks having different thicknesses are stacked together in a blank material obtained by pressing, as shown in FIG. 6 (a) due to a difference in thickness of each blank material. Then, the load is inclined in the direction of thinner thickness.

In order to prevent such inclination, as shown in FIG. 6B, a dimple such as a concave hole in the surface of a golf ball corresponding to the thickness difference between the blank materials 102 is formed. The (Dimple) 104 is formed in several places on each blank material, and such an apparatus for dimple molding is a dimple press working apparatus.

On the other hand, when forming the dimple on a blank material, the position of the dimple to be formed is set to X.
Expressed on the axis and the Y axis, the dimple depth Δt (= t1−
t2) is expressed and specified on the Z-axis, and the number of dimples to be formed is determined at an appropriate position according to the size of each blank material.

However, when dimples are formed on a blank material as described above, the locations and depths of the dimples vary depending on the size and thickness of the blank material. The department had to be replaced or corrected, with additional work.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 to 5 show a preferred embodiment of the present invention. Reference numeral 12 in FIG. 1 indicates the entire dimple press apparatus.

The dimple press device 12 is a processing device used for forming a dimple on a blank material, and is a material input section 1 into which a blank material 14 is input.
6, a material processing section for processing the blank material, and a material discharge section 18 for discharging the processed blank material.

The raw material charging section 16 is formed at the front side of the dimple press device 12, and the blank raw material processed in the previous stage of the dimple press processing according to the present invention is transferred while being aligned left and right by the guide bars 20 on both sides. A first chute conveyor 22 and a flat conveyor 24 for transferring a blank material coming out of the first chute conveyor to a material processing section at a constant speed.

The material processing section comprises a lower support section 26 to which the blank material fed from the flat conveyor 24 is transferred and settled, and an upper pressing section 28 having a punch for forming dimples in the blank material. Have been.

Here, as shown in FIG. 2, the upper pressing portion 28 is fixed to the upper frame 30 and slides up and down along a guide rail 34 formed on the side frame 32; It comprises a number of punches 38 mounted on the top and pressing dimples on a blank material.

The base plate 36 is connected to a hydraulic means 40 installed on the upper frame 30. The base plate 36 can be slid along the guide rails 34 by the hydraulic means so that the wheel 4
2 is formed, and a fastening hole 44 as shown in FIG. 3 is formed so that the punch 38 can be mounted using a fastening member such as a bolt.

In the above, the fastening holes 44 are tapped at a total of 104 locations at intervals of 8 columns and 13 rows.
The punch 38 is also provided with a total of 104 punches, so that a total of 104 dimples can be formed per blank material.

Further, if the fastening holes 44 are formed again in three rows for each location, the punches may be moved for each row depending on the blank material and mounted, so that the dimples formed on the blank material can be formed. Is possible up to a total of 312 locations.

On the other hand, as shown in FIGS. 2 and 4, the lower supporting portion 26 has a sensing means 46 for sensing whether or not a blank material is fed from the material feeding portion 16, and When a blank material is detected, a servo motor 48 that operates when the blank material is detected, a transfer conveyor 50 that transports the blank material by a predetermined distance, and a processing unit that is supported when the punch 38 of the upper pressing unit dimples the blank material. And a lower die 52 installed on the opposite side of the punch 38 to support the blank material.

The sensing means 46 is a sensor device for sensing the presence or absence of a blank material, and uses a general beam sensor.

The transfer conveyor 50 includes the punch 38
At the time of dimple processing, four rows are arranged on the side surface of the point where the punch 38 descends so as not to interfere with the processing operation, and are transferred or stopped by a servo motor 48 operated by an operation signal of a control unit 54, and In this example, the permanent magnet 56 is attached over the dimple processing section of the blank material so that the blank material is firmly fixed during the transfer of the blank material and the dimple processing.

The lower die 52 is prepared in various sizes according to the installation range of the punch so that the die corresponding to the die can be used alternately.

In the dimple press apparatus configured as described above, in order to cope with a change in the thickness of the blank material, as shown in FIG. 5, each corner of the base plate 36 of the upper pressing section 28 is A pin cup 60 having a concave central portion is formed, and a pin 64 inserted into the concave portion 62 of the pin cup is formed on the lower support portion 26.
Is formed, and a seam (Seam) 66 is set around the same.

When the operator changes the thickness of the seam according to the thickness of the blank material and installs the seam 66 on the outer periphery of the pin, the descending distance of the upper pressing portion is changed by the thickness of the seam. Therefore, the depth of the dimple processing can be adjusted.

A hydraulic means 40 for slidingly moving the upper pressing portion 28 is provided with an upper frame 30.
It is preferable that a safety fence 68 be installed on the upper frame 30 as a device for preventing a worker from falling when refilling oil.

On the other hand, the blank material dimple-processed by the upper pressing portion 28 is
Is transferred to the next stage of the dimple processing step according to the present invention.

As shown in FIG. 1, the material discharge section 18 is provided on both sides so that the blank material can be re-aligned left and right like the first chute conveyor 22 of the material input section. It comprises a second chute conveyor 58 on which the guide bar 20 is formed.

The working steps of the dimple press apparatus according to the present invention configured as described above are as follows.

First, the blank material 14 is aligned left and right by a first chute conveyor 22 so that the flat conveyor 24
Is transferred to the transfer conveyor 50 via

The loading of the blank material is sensed by the sensing means 46, whereby the servo motor operates the transfer conveyor 50 by a distance determined for each blank material to transfer the blank material to the processing position.

Here, the X-axis position value of the dimple processing is
The Y-axis position value is determined by the transfer amount of the blank material of the transfer conveyor 50, and the Y-axis position value is determined by changing the position of the punch 38 attached to the base plate 36 and mounting the lower die 52 by changing the blank material. Is a seam 6 fitted into the pin 64 of the lower support.
6 is determined.

When the base plate 36 slides down according to the dimple processing position determined as described above and the punch 38 forms dimples in the blank material, the blank material that has been processed is transferred to the second chute conveyor 58. To the next step, and the dimple processing of the dimple press device according to the present invention is completed.

[0031]

The dimple press device according to the present invention
Since the blank material of various forms can be subjected to dimple processing in one apparatus, the entire work process and work time can be reduced.

Further, automation from the input of the blank material to the unloading of the blank material becomes possible, and the production cost can be reduced.
