Description

Punching machine {the punch}

The present invention relates to a punching machine, and more specifically, punching machine which can form perforations of various sizes in documents and paper by forming the perforated pins in a complex and detached structure, and can easily adjust the interval of the insertion groove into which the paper is inserted. It is about.

In general, the punching machine is used to form perforations on top of documents when the documents and papers are often stored in a file or binder.

Therefore, the perforated paper and papers are to be stored with a string or tied to a holder formed in a binder or a file for a long time.

However, when the perforation is formed in the documents stored by binding with an iron strap with the punching machine forming a punch inserted into a holder of a binder or a file, the size of the punch is larger than the thickness of the iron strap, so that the papers are separated by the iron strap. It is not fixed, the problem that often occurs when the paper is torn by the iron string during use, there is a problem that you need to purchase a separate punching machine.

In addition, if the thickness of the paper inserted into the punching machine even a little thick, the troublesome punching work has to be divided by several times.

The present invention is designed to solve the above problems, the purpose is to form a perforation of various sizes on the paper and paper by configuring to detach, attach the perforated pin used in the punching machine.

In addition, another object of the present invention is to adjust the interval of the insertion groove into which the paper is inserted.

In order to achieve the above object, the present invention provides an insertion groove into which paper is inserted and the insertion groove is formed with a body frame having a moving hole through which a perforation pin moves up and down, and guides formed at both ends of one side of the body frame. The plate is formed to be hinged to the pressing rod for pressing the perforated pin, the perforated pin is inserted into the insertion hole formed in the elevating rod is formed with a fixing hole on one side to be fixed by a fixing bolt, both ends of the elevating rod It is installed as a guide hole formed in the guide plate can be moved up and down by an elastic spring, formed on both ends of the elevating rod is provided with a fixed cap is formed to detach, attach the perforated pins of various sizes, the elevating rod Is formed with a plurality of elastic projections on one side, the elastic projection is installed the elastic spring, the elastic The other side of the ring is formed to be inserted into the fixing projection formed on one side of the main body, the insertion groove is formed with a fastening groove to one side thereof, the fastening protrusion to be removed, attached to the fastening groove and the ball holes pins of various sizes The gap adjusting plate is formed is formed, the thickness of the gap adjusting plate is characterized in that it is formed in various ways.

1 is a perspective view of the present invention, when the configuration in detail

The punching machine 100 is formed with an insertion groove 11 for inserting paper, the body frame 1 fixed to the bottom and the perforation part 2 for punching the paper and the pressing part for pressing the perforation part 2 ( 3) consists of.

The main body frame 1 has an insertion groove 11 formed on the front surface thereof, and the insertion groove 11 is formed such that the gap adjusting plate 12 is detached and attached, and guides are provided at both upper ends of the insertion groove 11. The plate 13 is integrally formed, and the guide plate 13 is vertically elongated with the guide hole 13a in which the perforation part 2 is installed.

The pressing portion 3 is formed with a pressing table 31 which is hinged to the guide plate 13 with a pin, and the pressing bar 31 has a pressing rod 31a for pressing the perforated part 2. It is formed to be connected to both ends of the pressing table (31).

Figures 2a and 2b is a cross-sectional view showing the main portion of the present invention, Figure 2a is shown in the A-A cross-sectional view;

The perforated part 2 is formed in the guide hole 13a formed in the guide plate 13, and the perforated part 2 is provided with a lifting bar 21 provided in the guide hole 13a on both sides, In the center of the elevating bar (21) is formed an insertion hole (21a) is inserted into the perforated pin 22 is formed a fixing hole (22a) at the top, a plurality of elastic protrusions (21c) is formed on the lower surface, An elastic spring 25 is formed on the elastic protrusion 21c, and the elastic spring 25 is fixed to the fixing protrusion 14 formed on the upper surface of the main body frame 1.

In addition, a built-in hole (21b) is formed inside the elevating bar (21), a fixed bolt 23 is built in the built-in hole (21b), a fixed cap 24 at the end of the fixed bolt (23) It is formed to be detachable.

In addition, the upper and lower surfaces of the insertion groove 11, the moving holes 15, 15a are formed, and the insertion hole 11 while the perforated pin 22 moves up and down to the moving holes 15, 15a. Perforations can be formed in the paper provided in the).

Therefore, the perforated pin 22 is inserted into the fixing hole 22a of the elevating bar 21, and the fixing bolt 23 is inserted into the fixing hole 22a formed in the perforated pin 22 inserted therein. By being provided with the fixing cap 24 at the end of the fixing bolt 23, the perforated pin 22 can be fixed to the lifting bar (21).

In addition, in order to replace the perforated pin 22, the fixing cap 24 is removed, and when the fixing bolt 23 is separated from the lifting bar 21, the perforated pin 22 is moved to the hole 15. It can be separated downward through (15a).

In addition, the lifting bar 21 is to be able to move up and down elastically by the elastic spring (25).

2B is as shown in the sectional view B-B;

A plurality of fastening grooves 11a are formed on the rear surface of the insertion groove 11 formed on the front surface of the main body frame 1, and the fastening protrusions 12a which are detached and attached to the fastening grooves 11a are disposed on the gap adjusting plate. It is formed on the rear of the (12), the control hole 12b corresponding to the perforated pin 22 is formed in the center of the gap adjusting plate 12.

In addition, the bottom surface of the main body frame (1) is provided with a rubber packing that can be stored paper punched by the perforated pin (22).
