The present invention relates to an angle punching apparatus, and more particularly, to an angle punching apparatus capable of performing punching in a state in which a gap between holes to be punched on an angle is easily adjusted to a use place.

Generally, an angle is an iron rod curved into an 'a' shape, and a plurality of holes for fastening bolts or the like are formed on each surface. The holes of these angles are perforated using a punching device.

A typical prior art related to the angle punching apparatus is an example of an angle punching apparatus (hereinafter referred to as prior art) disclosed in Korean Patent Application Publication No. 10-2012-0082481.

The prior art includes an angle mount portion fixedly installed on a base and having an angle to be machined and having a hole corresponding to a hole to be formed in the angle, and an angle mount portion provided at the front and rear of the angle mount portion, An angle holding cylinder and an angle holding unit for holding an angle when the pressing unit is pushed by a press in order to perforate a hole in an angle where the angle is held, and an angle holding unit A first pin and a first pin cylinder configured to accurately position the angle to be machined on the angle placing part and configured to protrude upward and downward through a hole formed on a left end side of the angle moving rail, For accurately positioning the angle to be machined on the placement unit, And that of a second pin and the first pin cylinder adapted to protrude down to become the upper side through a hole formed on the side right end of a technical base.

However, the distance between the holes punched in the angle should be adjusted according to the application. In order to do this, the interval between the tools of the apparatus for punching holes in the angle needs to be adjusted to flow, but in the conventional punching apparatus, It is necessary to provide a plurality of punching apparatuses that are manufactured to fit the gap between the holes of the angle because the means can not be provided. As a result, unnecessary equipment installation results in an increase in the production cost of the product due to the use of the equipment, This leads to problems.

In the following detailed description, exemplary embodiments of the present invention will be described in order to accomplish the above-mentioned technical problems. And other embodiments which may be presented by the present invention are replaced by descriptions in the constitution of the present invention.

FIG. 1 is a cross-sectional view of an angle punching apparatus according to a preferred embodiment of the present invention, and FIG. 2 is a cross-sectional view of FIG.

1 and 2, the angle punching apparatus 100 of the present invention includes a base 10, and an angle 1 mounted on the base 10 and formed in a " (20) and a press (40) located on the angle gusset (20) to puncture the hole (2) in the angle (1) raised by the angle gusset (20) by driving the cylinder .

The press 40 is a unit for perforating the hole 2 on the angle 1 mounted on the angle dock 20 and includes a press main body 50 vertically moving vertically by the power of the cylinder 30, A pin guiding hole 52 formed in the lower surface of the press main body 50 so as to penetrate the pin guiding hole 52; A pin height restricting hole 56 penetrating through the front surface of the press 40 and horizontally connected to the upper end of the pin guide hole 52 at right angles, The pins 54 are selectively inserted into the pin height-restricting holes 56 and exposed to the upper surface of the pin guide hole 52 in accordance with the downward movement of the press body 50 in a state of being in contact with the surface of the angle 1. [ A pin height restricting member (not shown) for restricting the height of the pin 54 60).

The press 40 having the above-described structure is configured such that the angle 1 is placed on the angle dock 20 and then the cylinder 30 is driven to lower the press main body 50 and the pin guide hole 50 of the press main body 50 The pins 54 in contact with the surface of the angle 1 are brought into contact with the surface of the angle 1 in accordance with the continuous downward movement of the press body 50 The pin height restriction hole 56 in which the pin height limiting member 60 is inserted is exposed out of the upper surface of the pin guide hole 52. At this time, among the plurality of pins 54 exposed in the pin guide hole 52, The pins 54 raised to the upper surface of the pin guide hole 52 which are horizontally and perpendicularly connected to each other are caught by the pin height restricting member 60 so that they can not be moved upward even if the press main body 50 performs a downward movement, In this state, the The pin 54 which is caught by the pin height restricting member 60 can not be raised upward and presses the surface of the angle 1, The hole 2 having the shape corresponding to the pin 54 can be punched out on the surface of the pin.

The pin height restricting member 60 is formed for the purpose of perforating the two holes 2 in the angle 1. The pin height restricting member 60 is integrally formed with the handle portion 62 and the insertion legs 64 are integrally extended from both ends.

The insertion legs 64 are inserted into two selected pin height-restricting holes 56 of the above-described pin height-limiting holes 56 of the press main body 50, 54).

The spacing between the holes (2) punched in the angle (1) may be varied according to the needs of the user. For this purpose, And the height between the pin height restriction holes 56 that limit the height of the pin 54 are different from each other so that the interval between the holes 2 punched in the angle 1 can be set to flow To be changed.

The spacing between the insertion legs 64 of the pin height restricting member 60 inserted into the pin height restricting holes 56 is also set at various intervals so as to match the spacing between the pin height restricting holes 56 Lt; / RTI >

Hereinafter, the operation of the angle punching apparatus according to the present invention will be described with reference to FIGS. 1 to 6.

First, when the hole 2 is to be formed on the surface of the angle 1 by using the angle punching apparatus 100 of the present invention, the angle 1 to be punched is placed on the angle dock 20.

Next, after selecting the pin height restricting member 60 corresponding to the interval between the holes 2 to be punched in the angle 1, the insertion leg 64 of the selected pin height restricting member 60 is inserted into the press main body 50, The height of the pin height (50) is adjusted by two pin height restricting holes (52) corresponding to the interval between the insertion legs (64) formed in the pin height restricting member (60) among the plurality of pin height restricting holes So that the insertion leg 64 of the limiting member 60 is inserted.

When the cylinder 30 is driven, the press main body 50 is lowered and the pins 54 inserted in the pin guide hole 52 of the press main body 50 are pressed against the surface of the angle 1 In this state, the pins 54 are exposed to the surface of the pin guide hole 52 while being in contact with the surface of the angle 1 in accordance with the continuous descending operation of the press body 50.

6, among the plurality of pins 54 exposed in the pin guide hole 52, a pin guide hole (not shown) connected to the pin height limiting hole 56 into which the pin height limiting member 60 is inserted The pins 54 inserted into the pin guide holes 52 do not rise to the upper surface of the pin guide hole 52 even if the press body 50 performs the lowering operation because it hits the insertion legs 64 of the pin height limiting member 60, The pins 54 engaged with the insertion legs 64 of the pin height restricting member 60 can not be raised upward as a result of the continuous downward movement of the press main body 50 in this state, (2) having a shape corresponding to the pin (54) is formed on the surface of the angle (1) by pressing the surface of the angle (1).

When the punching holes 2 are to be formed at different angles in the angle 1, the other pin height restricting members 60, which are designed to fit the corresponding holes 2, The hole 2 whose interval is adjusted can be easily punched in the angle 1 by performing a press operation in a state of being inserted into the pin height restricting hole 56 of the pin 1. That is, it is not necessary to provide a separate punching device for adjusting the spacing between the holes 2, and the punching operation can be performed by adjusting the interval between the holes 2 with a single punching device.
