Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a laminated plate-like material that can be efficiently perforated by laminating various flat plate materials used for forms, albums, various types of paper for electronic devices, etc. Regarding punching machines, document binding, bookbinding,
It can be used in a wide range of fields, such as perforated paper.

(Conventional technology) Conventionally, in the case of drilling machines for laminated flat plate materials, the drilling methods used are a press type that uses pressing force to drill holes, a rotation type that uses the rotational force of a motor, or an electromagnetic vibration or machine that uses the force generated by a commercial AC power source. Vibration type using physical vibration is often used.

(3) Problems to be solved by the invention The conventional press type 9-rotation type and vibration type both have problems, and the 50fi
Problems remained in all cases where more layers were stacked or where the pore diameter was as small as 5U or less.

If the laminated material is thick, the press type will wear out the drill and have poor durability and require a strong pressing force, making it unusable as an office tool, while the rotary type will not rotate due to increased frictional resistance between the drill and the inner circumferential surface of the drilling part. When the force decreases and downward pressure is applied to the drill, rotation often stops.Also, electromagnetic capture type and mechanical vibration type that use commercial power and use magnetic force generated by low frequency current generate noise. Not only that, but like the rotary type, the vibration is weakened due to wear resistance, the drilling force is poor, and the electromagnetic vibration type in particular has the disadvantage of generating heat due to overload.

(4) Means for Solving the Problems In order to solve the problems of the conventional art, the present invention uses a combination of a rotary type that rotates a drill and a vibration type that vibrates the rotating drill in high-speed longitudinal vibration using ultrasonic vibrations. This is a perforator that perforates laminated materials. In other words, the rotating inner cylinder is fitted inside an elevating outer cylinder that can move up and down using a plurality of vertically installed columns as guides.
The upper end is connected to the motor installed on the top of the full lifting outer cylinder,
This is a laminated plate material drilling machine that is equipped with a vibration magnifying horn that has the upper end of the drill attached to its tip, and a vibrator that is excited by high frequency voltage on the top of the vibration magnifying horn. be.

(5) Function The present invention perforates a laminated material while a rotating drill is imaged by ultrasonic vibrations, and the drill vibrates longitudinally due to the ultrasonic vibrations enhanced by a vibration magnifying horn while rotating. The frictional resistance with the inner circumferential surface of the drilling portion against rotation and descent is significantly reduced, and the cutting edge of the rotating drill is accompanied by a striking action, increasing the cutting force for drilling. Furthermore, since it is a high frequency, there is no misalignment and no noise like magnetic vibration is generated.

(6) Examples Next, the embodiment shown in FIGS. 1 and 2 will be described.

A plurality of pillars (z) are installed vertically on the platform (1), and a lifting outer cylinder (3) that can move up and down as a full guide is provided, and a plurality of bearings (■) are interposed inside the pillars, which are integrated with the lifting outer cylinder (3). Rotating inner cylinder] 4) Fully installed so that the rotating inner cylinder (

Geru. Inside the rotating inner cylinder (4), a vibrator (9) made of a semiconductor such as a ceramic, which is excited by a high frequency voltage, is completely mounted on the upper surface of a vibration magnifying horn (7).

In the embodiment configured in this way, the rotating inner cylinder (4)

In this state, the drill (8) is lowered by lowering the elevating outer cylinder (3) as shown in Fig. 3, and the laminated materials 01 are stacked on the table (1).
Drill a hole in 1.

('7) Effects of the Invention The present invention energizes a rotating drill with ultrasonic longitudinal imaging generated by a vibrator, so it is possible to drill holes in laminated materials efficiently without misalignment or noise. Therefore, it is particularly effective for drilling deep holes in thickly laminated flat plate materials.
