Abstract

To provide a method and a device, which enable notification of a processing position for a workpiece to be provided without physical contact so as to enhance safety during a press operation and expand availability of an amorphous workpiece.SOLUTION: The use of an optical guide 2 for positional notification makes notification of a processing-predetermined position 11 provided by irradiating a workpiece 8 from a mold 1 installed on a top plate. Thus, the workpiece 8 or a blade stop plate is displaced from the outside of a press area so as to enable continuous processing. In addition, since the mold do not have to be taken out in each press operation, dangerous operations within the press area can be reduced.SELECTED DRAWING: Figure 3

Description

The present invention relates to a mold with an optical guide for position notification and to a mold attached to a press.

With the punching die of the existing technology, there is a method in which the material to be processed is directly installed on the mold, or the material to be processed is set at a fixed position on a press machine table at a distance set using a press machine with a mechanism for moving the material material position. .

In a punching die for a single press machine without a position moving mechanism, a punching die that determines a processing position by contact with a material to be processed, such as a spring pin or an end face of a sponge, exists as an existing technology. However, this method requires removal of the processed product for each press, requires insertion of a hand into the press area, involves a risk of injury, and is difficult to process continuously.

The problem to be solved is that, in a single press machine without a position moving mechanism, there is a risk of injury by inserting a hand into the press area, and the determination of the processing position with respect to the work material depends only on physical contact. Thus, continuous press working is difficult.

In addition, when a press with a position moving mechanism is used, the material to be processed is limited to a band-like shape or the like, and is not suitable for discontinuous processing. In the case of using offcuts or maximally effective use of the surface of the material to be processed, a mechanism is required in which a single press machine is used to determine the processing position by the operator himself.

The punching die is installed and fixed on the upper plate of the press, and the optical guide for position notification implanted in the die irradiates the material to be processed, thereby visually recognizing the material and determining the planned processing position. After the pressing, the plate to be processed, on which the material to be processed is placed, or the material itself is moved to the processed position end along the light beam irradiated from the position notification optical guide.

In general, when performing punching with a press machine without a position moving mechanism, a punching die, a work material, and a plate for a blade are taken out of the press machine for each press, but if the present invention is used, the work piece is laid under the work material. By moving the blade contacting plate or the workpiece itself from outside the press area, there is no danger of a hand entering the press area, so that safety is improved. Further, since there is no need to remove the punching die for each press, the working speed can be increased. Furthermore, if the present invention is used with a one-side punching die such as a Thomson type, a pinnacle type or an engraving type, the die can be quickly re-installed. A scrap discharge punch blade or the like can be used.

It is an outline figure at the time of manufacturing a punching die arbitrarily. It is the outline figure which produced the punching die arbitrarily and looked through the holder attaching mechanism. It is a continuous work explanatory drawing at the time of setting a punching die in a press. FIG. 4 is an embodiment diagram in which the punching die itself has an adsorption function. It is an outline figure at the time of producing a top-to-bottom punching die arbitrarily.

In practicing the present invention, a small-diameter optical guide for position notification is implanted at a position close to the cutting blade, stamp or punch on the mold base, at a height not protruding from the blade tip. Further, by separating the power supply unit of the optical guide for position notification from the light source module, the power supply unit has a shape that can be easily arranged in any type of mold.

The punching blade shape shown in FIG. 2 is an example of a punching die manufactured in various shapes, and a plurality of optical guides for position notification are implanted according to the shape of the manufactured punching die, so that a clearer processing position can be obtained. We can announce information.

There are several types of light emitted from the optical guide for position notification, such as red and green, dots and lines, and crosses. However, it is point irradiation that can guarantee the positional information accuracy when an operator performs replacement. It is an optical guide for position notification of a type.

There is also a conventional method of attaching a mold body to a press machine without a mold installation mechanism using an adhesive material such as a double-sided tape. However, this method requires time to remove and insert the mold, and the punching die with scum discharge is not suitable because it requires detachment for each discharge operation. There are problems such as variations. Further, it is possible to obtain the same effect as in claim 1 by implanting a magnet in the mold body and not using a holder, but in the mold as shown in FIG. There is a danger that the operator may be injured when the punching die is stored.

Therefore, a mold using a holder has been devised as a form that can match molds of various weights and sizes. The engagement shape of the mounting part and the bar shape to be connected by inserting a rod pin through a through hole from the side of the mold base and holder and verifying it were verified. However, it was concluded that the engaging shape and the bar shape of the holder and the mold were not enough to perform a firm connection and easy attachment and detachment. FIG. 1 shows an example in which two holders are used, but it is necessary to increase the number and size of the holders to sufficiently hold and attract a large-weight mold.

Originally, presses without a position moving mechanism do not have many mold mounting mechanisms as existing mechanisms, and are only attached to C-type presses that mount up-and-down dies, other portal presses, etc. Less. Considering the simplicity of mold installation, it is better to manufacture a mounting mechanism with a hanging pinch type according to the size of the individual press machine, but since the size and shape are unique to each individual press machine, manufacturing When this is possible, a mold mounting mechanism derived from a press machine is desirable.

In the case of punching with a punching die, which is a type of die, or a top-to-bottom punching type Thomson, pinnacle, engraving, or the like, the material to be processed itself is moved because a blade contact plate is not used. Instead of using claim 1 for fixing to a press machine, a punching die mounting mechanism derived from the press machine is required. In addition, the guide post implanted in the vertical die body may interfere with the movement of the position of the workpiece in the conventional manufacturing method. In that case, only movement in one direction in the X-axis direction or the Y-axis direction is possible. However, if the guide post is manufactured by a mechanism capable of detaching the guide post exclusively for the present invention, and the punching processing surface is designed to be flat, it is possible to move the workpiece in both axial directions.

The embossing die, foil stamping die, or stamping die, as well as the punching die, notify the processing position to indicate the exact position of the continuous pattern and to avoid processing position variations when processing into large products. Becomes possible.

To date, there are many simple presses on the market, most of which are robust, and can be expected to be active in the press working industry for many years to come. Most of them are press machines without a position moving mechanism, and work efficiency is inferior to that of the present invention, and a hand must be inserted into the press area, which is a dangerous work. The present invention is considered to have great industrial value by reducing occupational accidents and effectively using scrap materials that have been discarded.

Position announcement for an optical red laser beam applied from the guide, green, points, lines, or are present several such cross the worker in points can ensure positional information accuracy in the exchange It is an irradiation type optical guide for position notification.

Therefore, a mold using a holder has been devised as a form that can match molds of various weights and sizes. First, as for the connection between the holder and the mold, the engagement shape of the mounting part and the bar shape to be connected by inserting a rod pin through a through hole from the side of the mold base and the holder and verifying the shape were verified. However, it was concluded that the engaging shape and the bar shape of the holder and the mold were not enough to perform a firm connection and easy attachment / detachment. In addition, the connection between the holder and the press machine employs a structure mainly based on magnetic force, and a magnet is implanted in a holder of a member such as resin or wood. FIG. 1 shows an example in which two holders are used, but it is necessary to increase the number and size of the holders to sufficiently hold and attract a large-weight mold.

When performing punching with a punching die, which is a type of die, or a Thomson blade , pinnacle blade, engraving blade, or the like, which is a top-to-bottom punching type, the workpiece itself is moved because a blade contact plate is not used. In addition, the guide post implanted in the vertical die body may interfere with the movement of the position of the workpiece in the conventional manufacturing method. In that case, only movement in one direction in the X-axis direction or the Y-axis direction is possible. However, if the guide post is manufactured by a mechanism capable of detaching the guide post exclusively for the present invention, and the punching processing surface is designed to be flat, it is possible to move the workpiece in both axial directions.
