Abstract

PURPOSE:To improve the accuracy of working dimension and the yield of a product by arranging an upper roll and a lower roll provided with projecting cutters and recessed cutters face to face on the external circumferential surface of metallic rolls and engaging =male cutters with female cutters and rotating them. CONSTITUTION:A perforator part 2 comprising an upper and a lower spindle 4, 5, an upper and a lower roll 6, 7 and a perforating roll 8 is provided on a frame 1b. Male die cutters 9 and female die cutters 10 are formed at a prescribed interval on the upper die roll 8a and the lower die roll 8b of the perforating roll 8. The male die cutter 9 are engaged tightly with the female die cutters 10 as the rolls 6, 7 rotate. An upper and a lower gear 11, 12 are driven by a driving motor 14 through a belt 17 and a metallic strip stock A is perforated continuously by the male die cutters 9 and the female die cutters 10 which are rotated. Since the perforation is executed continuously, the accuracy of working dimension is improved drastically. Therefore, the yield of the product also is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotary drilling machine for drilling holes of a desired shape at regular intervals in, for example, a strip-shaped thin metal plate.

[Conventional technology]

Conventionally, in order to drill a hole in a plate material such as a thin metal plate,
There is a punching process that involves the vertical movement of a press machine consisting of upper and lower dies.

[Problem to be solved by the invention]

However, in the punching process using this vertical movement,
It was extremely difficult to incorporate this into a continuous production line, as the base material, such as a thin metal plate, had to be stopped during punching. Moreover, this was almost impossible on a high-speed production line. Furthermore, it is possible to perform punching in synchronization with the flow direction of the line, but this is extremely difficult to control due to the relationship between the vertical movement of the upper and lower dies and the flow of the line, and the equipment costs are enormous. It had some drawbacks.

[Means to solve the problem]

In view of these points, the present invention provides a perforated roll in which a convex male blade is formed protrudingly on the outer peripheral surface of a metal roll, and a perforated roll in which a concave female blade is formed in the outer peripheral surface of a metal roll. The upper and lower die rolls are mounted vertically on a frame on a stand so that the male and female blades rotate in unison, allowing for high-speed drilling. It is possible to do this without stopping the line, and furthermore,
The present invention provides a rotary drilling machine with improved yield and dimensional accuracy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rotary drilling machine according to the present invention will be described in detail below with reference to the drawings. Fig. 1+81, (bl: on the rotary drilling machine according to the present invention (hereinafter simply referred to as the drilling machine)
A schematic explanatory diagram showing the above, and a cross-sectional view taken along the line E in Fig.
It consists of upper and lower main shafts 4.5, an upper roll 6, a lower roll 7, which are mounted on a frame 1b erected on a pedestal la, and a perforated roll. The upper and lower rolls 6.7 are for fixing the metal sheet material A in a predetermined position and transporting it at a predetermined speed by rotation thereof. Figure 2 (al, (b) (ta1)
As shown in the Rolo line cross-sectional view in the figure, along a predetermined position of the thin metal sheet material A, the so-called flow direction of the thin metal sheet material A,
It is used to form holes A+ at a predetermined pitch P, and consists of a metal upper roll 8a and a lower roll 8b. In the figure, the upper roll 8a has a convex male blade 9, and the lower roll 8b has a male blade 9. A concave female blade 10 is formed. In addition, hole A+
The pitch P of the upper and lower die rolls 8a is not limited.
, 8b, and the shape of the male and female blades 9.10 changes depending on the formation position of the male and female blades 9.10, as shown in FIGS. 3(al to (f)). The shape of the hole A1 can be selected by .More specifically, as shown in Figures 4 and 5, the male and female blades 9.10 rotate at the same speed as the flow direction into the thin metal sheet. , male, female blade 9.1o
A hole A+ is formed in the thin metal plate material A by the two meshing together. Although the dimensions vary depending on the diameters of the upper and lower rolls 8a and 8b, the height h of the male blade 9, and the shape, there is a gap between the male blade 9 and the female blade 10 as shown in FIG. It forms a gap of Δt, and this gap Δt allows the male,
Adjustment is made so that the male and female blades 9.10 do not collide when the female blades 9.10 engage. Further, the concave female blade 10 is a hole that penetrates to the back surface, and the cut-out perforated pieces A2 are successively pushed and discharged. 6
a is a movable body, which moves the upper main shaft 4 upward when not forming a hole A+ in the thin metal plate A, and forms a hole A+ in the thin metal plate A;
For example, it is a rotary type. 11 is an upper gear, 12 is a lower gear,
The drive of the motor 14 of the drive source is transmitted to the upper gear 11 by the lower gear 12, and the rotation speed and speed of the drilling part ↓ are adjusted.
It is for communicating. The drive source U is a motor etc. 14
, a heald wheel 15, 16, and a belt 17, and the rotation of the motor etc. 14 is transmitted to the lower main shaft 5, which in turn is transmitted to the upper and lower gears 11, 12 to drive the top of the perforation. In addition, 18 is a presser roll, which has two parts attached to the main shaft 19.
This is to prevent the thin metal sheet material A from shifting from side to side by forming it individually and installing it with the same width as the width of the thin metal sheet material.

Of course, in the diagram it is attached after the perforation ↓, but before and after,
Alternatively, it can be attached only to the front.

Reference numeral 20 denotes a receiving tray, and the receiving tray is used to collect the perforated pieces A2 cut out by the perforating roller at a - point so that the perforated pieces A2 are not scattered.

Next, the operation on the drilling machine according to the present invention will be briefly explained. The configuration on the drilling machine is as shown in Fig. 1 (a) and (bl), and on this drilling machine, the thickness of 0.4 mm,
Figure 3 (8
Make the dragon hole A1 of width 31 and length 10 as shown in 1 to 45 mm.
Assume that the holes are to be drilled continuously in a pinch. Then, the motor 14 is operated, and the rotation is adjusted so that the upper and lower roll parts ↓ of the perforation part and the perforation roll part rotate at a speed of 25 m/min. Of course, at this time, the upper main shaft 4 is lowered by the movable body 6a, and the male and female blades 9.10
are adjusted to mesh in a predetermined position. On the other hand, the thin metal plate material made of the colored aluminum iron plate is conveyed to the entrance portion of the punching machine by pinch rollers, free rollers, etc. (not shown). After that, when the metal thin plate material A is inserted onto the drilling part on the rotating drilling machine as described above, a hole AI as shown in FIG. Of course, the metal thin plate material A may be of a fixed length or may be turned into a long shape.

What has been described above is only the actual male side of the drilling machine according to the present invention, and the free roller 21 shown in FIG.
It is also possible to form a structure to ensure the conveyance of the thin metal sheet material A. Also, instead of integrating the frame 1a and the frame 'JAtb, a rail is formed on the frame la so that the frame (on the drilling machine) can move on this rail, and the hole AI is placed at an arbitrary position on the thin metal plate material A. It can also be made possible to form. Note that in this case, the presser roll 18 is in a movable state. Of course, instead of a thin metal plate material, a synthetic resin base material or a composite plate can also be perforated. Furthermore, it is also possible to form a plurality of perforated roll groups.

〔Effect of the invention〕

As explained above, the rotary perforation machine according to the present invention has the characteristics that it can be incorporated into a high-speed line and can produce perforated plates with high dimensional accuracy at a high yield because it is a rotary perforation machine. There is.
