Abstract

(57) [Abstract] [Purpose] It is an object to provide a material holding structure capable of accurately punching a thin plate such as a metal mask at high speed. [Structure] In a punch press that performs punching on a material to be processed with a die, at the time of drilling the material to be processed,
A clamper for holding one side of the material to be processed and a retainer for pressing and holding the material to be processed in the vicinity of the other side of the material to be processed are provided at a position facing the roller above the material feed roller closest to the mold. . [Effect] Since the material to be processed is pressed and held by the material retainer each time when the hole is machined, the hole can be machined in a state where the waviness caused by the vibration or sudden stop of the material itself is effectively removed. Accurate drilling is possible even when processing thin plates such as masks at high speed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a material holding structure for a punch press. In particular, this proposal relates to a thin plate holding structure when punching a thin plate used for a metal mask or the like by punching.

[0002]

[Prior art]

 A thin plate (for example, a thickness of 0.2 mm to 0.3 mm) of a metal mask is processed by punching while holding the thin plate so that the thin plate does not shift when punching. As the holding structure, a holding structure as shown in FIGS. 5 and 6 is generally used. FIG. 5 is a plan view of a conventional thin plate processing apparatus, and FIG. 6 is a side view of FIG.

[0003] Hereinafter, a holding structure for processing a material to be processed in this thin plate processing apparatus will be described.

In FIG. 5, 1 is a base, 2 is a rail arranged on the upper surface of the base, 3 is a rail on the rail 2, and an X-axis moving body that moves in the X-axis direction using an X-axis motor 4 as a drive source, and 5 is an X-axis moving body. Axis mover 3 Y-axis rails arranged in the Y-axis direction, 6 is a Y-axis mover that moves on the Y-axis rail 5 in the Y-axis direction using a Y-axis motor 7 as a drive source, and 8 is a Y-axis mover. 6 is a clamper, 9 is a material feed roller provided on the X-axis moving body, 10 is a mold mounting base, 11 is a mold mounted on the peripheral portion of the mold mounting base 10, and 12 shown in FIG. 6 is a stripper. , 13 are die mounts, and 14 is a die.

As shown in FIG. 5, one side of the material to be processed 15 is sandwiched and held by a clamper 8, and the held material to be processed 15 is moved in the Y-axis direction as shown in FIG. 6 moves along the Y-axis rail 5 using the Y-axis motor 7 as a drive source. At the time of movement, the material feed roller 9 rotates in accordance with the movement of the work material 15 in order to smoothly move the work material 15.

In the movement of the material 15 to be processed in the X-axis direction, the X-axis moving body 3 moves along the X-axis rail 2 using the X-axis motor 4 as a drive source. The workpiece 15 is set at a predetermined position by the movement in the X and Y directions. The material 15 to be processed set in a predetermined position is subjected to predetermined drilling by the die 11 provided on the die mount 10 and the die 14 provided on the die mount 13. By repeating this operation in sequence, holes are drilled in the necessary portions of the material 15 to be processed.

When all the drilling processes are completed, the clamper 8 is released, the work material 15 is removed, and a new work material 15 is replaced.

[0008]

[Problems to be solved by the device]

 Thus, in the conventional holding structure, one side of the material 15 to be processed is held by the clampers 8 provided at two locations.

Therefore, when the Y-axis moving body 6 shown in FIG. 6 moves in the Y-axis direction, or when the X-axis moving body 3 moves in the X-axis direction, if the moving speed becomes fast, the workpiece material At 15, vibration occurs due to movement, and a waviness phenomenon occurs due to sudden stop of the Y-axis moving body.

When drilling is performed in that state, a deviation from a predetermined position to be drilled may occur, and it may not be possible to drill at an accurate position.

The present invention has been made in view of the above problems, and an object thereof is to provide a material holding structure capable of accurately and accurately punching a thin plate such as a metal mask.

[0012]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a material pressing tool on the upper part facing the material feeding roller closest to the mold, and the material pressing tool is used to cut the material to be processed each time the material is punched. Press and hold.

[0013]

【Example】

 Hereinafter, a case of punching a thin plate according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 is a plan view of the thin plate processing apparatus of the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is an enlarged view of part A of FIG. 2 in a state where the material pressing tool is separated from the material feeding roller, and FIG. FIG. 3 is an enlarged view of a portion A of FIG. 2 in a state where the tool presses the material 15 to be processed.

The same components as those of the conventional example shown in FIGS. 1 to 4 are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIGS. 1 and 2, in the X-axis moving body 3, a material pressing member 17 is provided as follows at a position facing the upper part of the material feeding roller 9 a closest to the mold 11.

As shown in FIG. 3, the material retainer 17 has a movable shaft 19 of a solenoid 16 fixed to the base 1 inserted through through holes provided in supporting portions 21 provided at both ends thereof. It is fixed to the movable shaft 19 by a nut 20a and a nut 20b which are screwed into the screw 19.

With the above configuration, the material pressing member 17 is moved up and down by moving the movable shaft 19 of the solenoid 16 up and down.

Next, a case of processing the material 15 to be processed according to the present invention will be described with reference to FIGS.

As shown in FIG. 1, first, one side of the material to be processed 15 is sandwiched and held by the clamper 8.

As shown in FIG. 2, the Y-axis moving body 6 of the held work material 15 is moved to a predetermined position by the Y-axis motor 7.
