Description

[0001] Angle punching machine [0002]

The present invention relates to an angle punching apparatus, and more particularly, to an angle punching apparatus capable of producing a small, inexpensive, simple structure using hydraulic pressure, which punches holes formed along the longitudinal direction of an angle.

In general, angles are used in a variety of applications such as prefabricated shelves, construction and machine accessories, and band-shaped metal bars are bent to "a", "t", "c", and so on. The angle is formed with a circular or rectangular hole along the longitudinal direction.

As such an apparatus for punching holes in an angle, an angle punching apparatus of Patent Publication No. 10-2012-0082481 has been proposed, and most of them are middle-sized and high-priced equipment using presses.

Such a conventional angle punching apparatus is economically burdensome to purchase and occupies a large installation space as a large size. Particularly, when drilling the necessary holes in the use and installation places, the drilling operation is dependent on one by one, which causes a drastic decrease in the work efficiency.

In addition, the conventional hydraulic working punching device is integral with casting, heavy in weight, high in manufacturing cost, and inconvenient to repair.

Patent Document 1. Patent Publication No. 10-2012-0082481 (July 24, 2012)

The angle punching apparatus according to the present invention is a small-sized angle punching apparatus using oil pressure which can be easily purchased at low cost without economic burden without occupying much space.

Another object of the present invention is to provide an angle punching fitting using an oil pressure which is easy to disassemble and repair as an assembly and is light in weight and easy to move.

It is another object of the present invention to provide an angle punching apparatus capable of constantly drilling a gap between punched holes.

In the angle punching apparatus according to the present invention, a cylinder fixing table 50 is attached to the upper portion between the side frames 52 on both sides, and a die holder 44 is assembled to the lower side; A cylinder 10 is mounted vertically on the cylinder fixing table 50. A punch 30 is mounted on the lower end of the piston 20 by means of an assembly tool 32, The die 40 having the hole is assembled and detached by the fixing bolt 46. [

A stopper 36 is attached to both sides of the punch 30 and a fixing pin 60 is provided to one side or both sides of the die 40 for laterally transporting the die.

The most significant advantage of the present invention is that it can be manufactured at low cost by eliminating the problem of a high manufacturing cost due to casting because it is manufactured in a small size and light weight in a prefabricated manner and can be simply punched It is possible to greatly increase the working efficiency, and it is possible to perforate the hole with a constant interval at a simple configuration.

2 is a partial perspective view of an angle punching apparatus according to a preferred embodiment of the present invention.
3 is a central cross-sectional view of an angle punching apparatus according to a preferred embodiment of the present invention.
4 is a cross-sectional view illustrating an operating state of an angle punching apparatus according to a preferred embodiment of the present invention.

Best Mode for Carrying Out the Invention Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Like reference numerals can be used for similar elements in connection with the description of the drawings.

In the angle punching apparatus according to the embodiment of the present invention, the cylinder fixing table 50 is attached to the upper part between the side frames 52 on both sides and the dice holder 44 is assembled to the lower side; A cylinder 10 is mounted vertically on the cylinder fixing table 50. A punch 30 is mounted on the lower end of the piston 20 by means of an assembly tool 32, The die 40 having the hole is assembled and detached by the fixing bolt 46. [

The above is explained in more detail as follows.

FIG. 1 and FIG. 2 are perspective views of all and a part of an angle punching apparatus according to a preferred embodiment of the present invention, and FIGS. 2 and 3 show cross sections for illustrating an operating state of the present invention.

According to the drawings, the side frames 52 on both sides where the openings 53 are formed at the front middle portion are provided, and the cylinder fixing table 50 is fixed to the upper portions between the side frames 52 by the assembly bolts 54 Horizontally. And the die holder 44 is assembled to the lower portion of the lower portion, that is, the lower portion of the opening portion 53 by the assembly bolts 56.

The cylinder 10 is mounted vertically on the cylinder fixing table 50. At this time, the cylinder 10 may be operated by an external hydraulic device or by air pressure.

A punch 30 is mounted on the lower end of the piston 20, which is operated vertically by the cylinder 10. The punch 30 is detachably attached to the lower end of the piston by an assembly tool 32 that is screwed into the piston.

Next, a die 40 having the above-described punch 30 and the integral hole 42 is assembled to the die holder 44 by a fixing bolt 46. Therefore, the die 40 is also detached and attached to the punch in accordance with the size of the angle hole.

At this time, a stopper 36 is attached to both sides of the punch 30 to block the angle from rising along the punch 30 that ascends and descends after punching.

A fixing pin 60 is provided on one side or both sides of the die 40 by a predetermined conveying means. That is, the fixing pin 60 is for fixing the position so that the angle 200 can be precisely positioned and the interval between the holes 210 to be punched is fixed, and the fixing pin 60 A threaded rod 62 is provided on the side frame.

A feed path 58 is formed laterally on the upper surface of the opening 53 of the side frame 52. A screw rod 62 is inserted and assembled in the center of the feed path, 64 are formed. A fixing pin 60 moving horizontally along the conveying path 58 is screwed to the screw rod 62 so that the fixing pin 60 is transferred to the left and right as the screw rod is rotated by the knob 64 .

In the angle punching apparatus of the present invention configured as described above, the angle 200 is inserted between the both side openings 53 and is placed on the lower die hole 42 so that the positions to be drilled match. Thereafter, as the punch 30 is lowered by the operation of the cylinder, a predetermined hole is drilled in the angle, and the scrap 220 falls down.

At this time, in order to continuously punch the holes 210 with a constant length, the distance between the punch and the dice is adjusted so that the fixing pin 60 is inserted into the perforated hole 210 It is possible to perforate the hole having a constant interval at all times as the punching is performed.
