Description

[Detailed description of the invention] [Industrial application field] This invention relates to a punch press, and more specifically, a workpiece such as a fixed-length plate is moved and positioned in the X-axis direction, and the workpiece is processed. punch to do,
The present invention relates to a punch press in which a mold holder equipped with a die can be moved and positioned in the Y-axis direction.

[Prior art]

Conventionally, punch presses perform punching on workpieces such as regular-sized plates. It is common to have a configuration in which the workpiece is moved and positioned in the X-axis and Y-axis directions with respect to the processing position.

[Problem that the invention attempts to solve]

In other words, conventionally, a carriage equipped with a workpiece clamp is supported on a carriage base that can be moved and positioned freely in the Y-axis direction, and the workpiece clamped by the workpiece clamp is moved along the X-axis. , is configured to move in the Y-axis direction.

Therefore, there is a problem that the table that supports the workpiece such as a regular-sized plate becomes relatively large, and if the positioning accuracy in the Y-axis direction deteriorates, for example, the carriage is supported by the carriage base. Therefore, there is a problem that positioning accuracy in the X-axis direction is also affected.

[Means to solve the problem]

In view of the above-mentioned conventional problems, this invention provides a carriage equipped with a gripping claw device for gripping the workpiece on a table that supports the workpiece, so as to be movable and positionable in the X-axis direction. A movable bolster that removably supports a mold holder supporting a punch and a die for processing the workpiece is mounted on the table so as to be movable and positionable in the Y-axis direction perpendicular to the moving direction of the carriage. a mold storage device for storing a plurality of mold holders is provided at a position adjacent to the table; appropriate mold holders stored in the mold storage device and mold holders supported by the movable bolster; The device is equipped with an exchange device that lifts up and removes and replaces the parts.

[Effect]

In the above configuration, when the workpiece is gripped by the gripping device, by moving and positioning the carriage in the X-axis direction, the workpiece is
It can be moved and positioned in the axial direction. Also,
By moving the movable bolster in the Y-axis direction,
The mold holder can be moved and positioned in the Y-axis direction. Therefore, the workpiece can be punched at any position along the X and Y axes using the punch and die supported by the mold holder.

Furthermore, the mold holder can be attached to and removed from the movable bolster by an exchange device, and various punches and dies can be used.

〔Example〕

FIG. 1 shows only the portion below the table 3 of a punch press 1 according to an embodiment of the present invention.

In the actual example, the table 3 is approximately T-shaped in plan view, with a long rear central portion, and mold storage devices 7, 7 each having a caterpillar plate 5 which can be freely positioned and circulated are provided on both sides thereof.

Near the inner end (press table 3 side) of the above-mentioned caterpillar plate 5 is a column part 11 of the mold holder 9.
An engagement hole 15 is provided at the lower end into which a lower clamp arbor 13 (see FIG. 3) engages.

A punch 19 is attached to the upper arm 17 of the mold holder 9, and a die 23 is attached to the lower arm 21 in pairs.

What is installed perpendicularly to the rear end of the T-shape of table 3 is
This is an exchange device 29 for transferring a mold holder 9 between a caterpillar plate 5 and a movable bolster 27 provided in a central groove 25 of a table 3.

As shown in FIG. 3, this exchange device 29 is equipped with a lift 31 containing, for example, a fluid pressure cylinder, and a rotary actuator (not shown), so that it can move up and down and rotate freely.

A pinwheel-shaped claw member 33 is provided on the top surface of the exchange device 29, and an upper clamp arbor 35 is provided in a protruding state on the top end surface of the column portion 11 of the mold holder 9.

The above-mentioned movable bolster 27 is screwed into a lead screw 37 provided in the central groove 25 in the depth direction of the T-shaped table 3, and is moved and positioned in the front-rear direction (Y-axis direction in FIG. 1) by a servo motor 39. .

Further, a carriage 41 is provided at the front end of the table 3 in the X-axis direction and is provided with a gripping claw device 43, and is driven by a servo motor 45 to move and position the workpiece W in the X-axis direction.

Shown at the upper left end of FIG. 3 is an upper component 47 of the punch press including a striker and the like.

In the apparatus according to the present invention described in detail above, punch and die pairs are attached to a large number of mold holders and stored in a storage device equipped with a caterpillar plate. It is provided in

A desired mold holder from among these many mold holders is positioned in front of the exchange device and transferred from the caterpillar plate onto the movable bolster, and the movable bolster is moved in the direction of approaching and away from the workpiece by numerical control. Move and position.

A carriage and a gripping device are provided near the front end of the table and can be moved and positioned in a direction perpendicular to the direction of movement of the movable bolster by numerical control.
The workpiece is moved and positioned exclusively in this direction.

In this way, the desired press work can be performed on the desired position of the workpiece, and the mold can be replaced freely.

[Effect of idea]

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration. A carriage 41 equipped with a gripping claw device 43 is provided on the table 3 supporting the workpiece W so as to be movable and positionable in the X-axis direction. A movable holder 27 that detachably holds the mold holder 9 is provided so as to be movable and positioned in the Y-axis direction perpendicular to the X-axis. A mold storage device 7 for storing a plurality of mold holders 9 is provided adjacent to the table 3, and the mold holders 9 of the mold storage device 7 and the mold holders 9 on the movable bolster 27 are provided. A replacement device 29 is provided for lifting and removing and replacing the parts.

That is, according to the present invention, since the workpiece W only needs to be moved in the X-axis direction, compared to the case where the workpiece W is moved in the X- and Y-axis directions,
This allows the table 3 to be configured relatively compactly.

Further, a carriage 41 for moving and positioning the workpiece W in the X-axis direction is mounted on the table 3, and a movable bolster 27 for moving and positioning the mold holder 9 in the Y-axis direction is installed on the table 3. Y
Since the configuration for performing relative positioning in the axial direction is provided separately, the positioning devices in the X and Y axis directions do not influence each other, and the positioning accuracy is improved.

Further, according to the present invention, various types of mold holders 9 can be attached to and removed from the movable bolster 27, so that various types of processing can be performed.
