Description

Tie Pin for Fixing Aluminum Mold and Method for Menufacturing of the Same}

The present invention relates to a tie pin for fixing aluminum dies, and more particularly, to a tie pin that is easy to manufacture, inexpensive, and lighter than a conventional tie pin.

In general, the formwork is used to build a concrete retaining wall in the construction, the modern aluminum panel that can be reused a lot more times than the plywood is used a lot.

The aluminum formwork fixing tie pins are used to fasten the aluminum formwork using the aluminum panel to each other, and the conventional general aluminum formwork fixing tie pins 104 are connected to the aluminum formwork 100 as shown in FIG. 1. A cylindrical insert portion 106 fitted to the ball 102 is formed, and a flange-shaped engaging portion 108 fixed to the inlet of the connection hole 102 at the rear end of the insert portion 106 is formed. Is formed integrally connected, the inclined entry portion of the cone (cone) shape so that the insertion portion 106 is smoothly fitted into the connection hole 102 of the aluminum die 100 at the front end of the insertion portion 106 ( 109 is formed integrally connected to each other, and a fitting hole 110 into which the wedge pin 112 is fitted is formed at the outer circumference of the insertion part 106.

However, the conventional general tie pin configured as described above has a problem in that the work of processing the fitting hole in the insertion portion having a relatively large diameter is not easy, and in this process, the pin is bent.

In addition, because the weight goes a lot, the worker fastening the formwork is very difficult to carry a number of tie pins on the body, there was a problem that the price as expensive as the weight of the tie pins.

The present invention with respect to the problems as described above is an object of providing a tie pin for fixing the aluminum formwork, which is easier to manufacture, cheaper price, lighter.

The above object is, in the general aluminum die fixing tie pins which are inserted into the connection hole of the aluminum formwork and interconnects a plurality of aluminum formwork,

Forming plate having a predetermined thickness is punched and bent by a press, the insertion portion having a semi-circular curved surface of the cross section that is fitted in close contact with the connection hole of the aluminum formwork is formed, the rear end of the insertion portion is the connection hole The engaging portion fixed to the inlet of the projection is formed so as to extend in a radial direction from the center of the insertion portion, the entry portion of the semi-circular cross-sectional inclined inclined portion so that the insertion portion is smoothly fitted into the connecting hole of the aluminum die It is integrally formed to be connected, the outer periphery of the insertion portion is achieved by the aluminum die fixing tie pin, characterized in that formed through-insertion hole through which the wedge pin is fitted.

According to the above configuration, the production is easy, the productivity is improved, inexpensive aluminum formwork fixing pins are provided.

In addition, a lightweight aluminum formwork fixing pin is provided so that the operator can perform the work more easily when the formwork is fastened.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view of a tie pin for fixing aluminum formwork according to an embodiment of the present invention. 3 and 4 is a process flow chart shown to explain the manufacturing process of the aluminum formwork fixing pins according to an embodiment of the present invention.

As shown in Figure 2, the aluminum die fixing tie pin 2 according to the embodiment of the present invention is largely composed of the insertion portion 4 and the engaging portion (6).

The inserting portion 4 is a portion fitted into the connection hole 102 of the aluminum die 100, and is bent by a press to form a curved surface 10 having a semicircular cross section. An inclined entry slope 14 is formed at the tip end of the insertion part 4 toward the end 4a so that the insertion part 4 is easily fitted into the connection hole 102. The outer periphery of the insertion portion 4 is formed so that the fitting hole 8 through which the wedge pin 112 is fitted. Wherein the wedge pin 112 is fitted into the fitting hole 8 of the insertion portion 4 inserted into the connection hole 102 to interconnect the aluminum die 100 to secure the insertion portion 4 does not fall out It is for.

The locking portion 6 is formed to protrude in the radial direction from the center of the insertion portion 4 to the rear end of the insertion portion 4, the tie pin inserted into the connection hole 102 ( 2) is to be fixed to the inlet of the connection hole 102.

The manufacturing process of the present invention configured as described above will be described with reference to FIG. 3.

First, the forming plate P having a predetermined thickness is punched by a press to insert the insertion portion 4 inserted into the connection hole 102 and the engaging portion 6 fixed to the entrance of the connection hole 102 and the connection. The insertion piece 12 is formed to cut the insertion piece 12 to smoothly fit the insertion portion 4 to the ball 102. (External cutting step); Then, the insert portion 4 of the fitting piece 12 is bent by a press to form a curved surface 10 having a semi-circular cross section fitted in close contact with the inner circumferential surface of the connecting hole 102 of the aluminum die 100. (Curve forming step); Then, when punched with a press to form a fitting hole 8 into which the wedge pin 112 is fitted in the insertion portion 4 (long hole forming step), the aluminum formwork fixing tie pin according to an embodiment of the present invention (2). ) Is produced.

Here, the long hole forming step may be included in the contour cutting step or the curved surface forming step, but it is preferable that the long hole forming step is performed after the curved surface forming step to prevent the fitting hole 8 from being deformed in the curved surface forming step. something to do.

In addition, the manufacturing process of the present invention, as shown in Figure 4,

Curved forming step of forming a curved surface (10) having a semi-circular cross-section is bent in close contact with the inner peripheral surface of the connecting hole 102 of the aluminum die 100 by bending the forming plate (P) having a predetermined thickness; The inserting portion 4 inserted into the connecting hole 102 and the engaging portion 6 fixed to the inlet of the connecting hole 102 by punching the forming plate P on which the curved surface 10 is formed. And cutting the fitting piece 12 in which the inclined portion 14 is formed to smoothly fit the insertion portion 4 into the connection hole 102. It may be composed of a long hole forming step of forming a fitting hole 8 through which the wedge pin 112 is fitted into the inserting portion 4 by punching.

Here, the long hole forming step may be included in the outline cutting step.

1 is a perspective view showing a state of use of a conventional general aluminum die fixing pin.

Figure 2 is a perspective view showing the state of use of the aluminum die fixing tie pin according to an embodiment of the present invention.
