Description

Multi-Axis Drilling Machine for Tape Shapes {MULTI-AXIS PUNCHING DEVICE FOR TAPE TYPE OBJECT}

TECHNICAL FIELD This invention relates to the multiaxial drilling apparatus of a tape-shaped object.

Conventionally, the multiaxial milling machine of a tape-shaped object is desired to be punched by a puncher provided with a tape-like object to a feeding device from a roll disk.

The punching machine of this multi-axis punching device is a grid pattern punching method or a gap pattern punching method, and has a structure shown in FIG.

Fig. 5 shows a stripper plate 74 on a press ram B which is installed in the upper half u1 of the punching unit U showing the shape of コ and viewed from the side which can be controlled to move in the X and Y axis directions. ), The passive drive source 44 is mounted on the pressram B, and the punch support type 64 is installed by connecting to the passive drive source 44, and the lower half of the punching unit U ( u2), the die supporting die 54 is supported, and the perforator itself is controlled to move in the X and Y axis directions, or the workpiece is controlled to move in the X and Y axis directions as well, and the punch is driven by the driving drive source 44. The supporting die 64 is punched and punched out.

Fig. 6 shows the rectangular main frame 4 " assembled by connecting with the transverse frame 84 and viewed from the front, and providing the guide rails L3 and L3 on opposite inner surfaces of the main frame 4 ". In the same manner, the guide rails L3 and L3 face the front face in such a manner that the rectangular base frame 94 is slidably coupled thereto, and a die support 54 is provided on the upper surface of the base frame 94. A stripper plate 74 disposed between the punch support die 64 and the die support die 54 is provided in the upper frame 14 of the body frame 4 ″, and the base frame 94 is mounted on the body frame 4. Ball screw mechanism to move up and down, and control and move the puncher in the X and Y axis direction to drive the punch support type 64 with the drive of the passive drive source 44 to punch and punch. do.

By the way, the former shown in FIG. 5 and the latter shown in FIG. 6 can also be punched in a state in which the stripper plate 74 is approached to the workpiece corresponding to the thickness of the tape-like workpiece (workpiece) that is the object of drilling. .

For this reason, for example, pressing force is preferable for punching a pulp-like article laminated with, for example, a ceramic green sheet or the like that is easily rolled.

However, since the former supports the punch support die 64 and the die support die 54 to the U-shaped punching unit U having an open front, it is punched by the grid pattern drilling method or the gap pattern drilling method. In this case, there is a problem in that the upper half portion u1 of the punching unit U fluctuates slightly in response to the reaction force that collectively passively punches a plurality of punches, resulting in poor fabric process density.

In addition, since the latter is the structure which accommodates the reaction force pressure at the time of punching by the said punching method in the main body frame 4 ", there is no problem of worsening the drilling process density, but the main frame 4" and the base frame Since 94 is weighted, there is a problem that it is unsuitable for high-speed drilling and poor productivity.

The present invention has been made in view of the above conventional circumstances, and an object thereof is to provide a multiaxial fabric mill of a tape-shaped product which improves productivity as well as fabric process density.

In order to solve the above-mentioned object, the cardinal means inserts an upper frame mounted with a passive driving source connected to a punch support type, and a lower frame disposed below the die support type and a base plate supporting the die support type. In addition to connecting with a plurality of guide posts passed through, a stripper plate disposed between the die support type and the punch support type is installed in the upper frame to form a punching die, and form a space for carrying a tape-shaped material between the guide posts. The guide post is made to be capable of vertically movable control with respect to the base plate, and the same base plate is controlled so as to be controlled to move in the X-Y axis direction, and as a kind of object to be drilled, For example, if a pressing force such as a ceramic green sheet is applied, Laminated may be a tape-like materials.

The guide post is disposed at a position corresponding to each intersection point of the equilateral triangle (virtual), for example, as a base plate supporting the die support die, and viewed in a plane surrounding the die support die, or punching the base plate. It is preferable to arrange | position each at the position corresponded to each intersection of a square (virtual) by looking at the plane which surrounds a support type | mold and a die support type.

According to the above means, the guide post is moved up and down with respect to the base plate supporting the die supporting die, and the stripper plate provided on the upper frame is brought close to the tape-like object to be punched, and the passive driving source is driven to punch the die supporting die. Move punch downward to punch.

The reaction force during the drilling process receives the pressure in the engagement structure consisting of a plurality of guide posts connected to the upper frame, the lower frame, and both frames.

In addition, in punching a tape-like object by a grid pattern punching method or a gap pattern punching method, a punching die made of a base plate supporting the joining structure, a passive driving source, a stripper plate, a punch support type, and a die support type is used. Control shift in the X and Y axis directions.
