Method for manufacturing door frame attached wrap and therby door frame}

The present invention relates to a method of manufacturing a door frame and a door frame manufactured by the method, and more particularly, by using a low-cost raw material in the interior of the main body portion of the door frame, and using an expensive raw material on the outside. To construct the door frame body, and attach lapping materials such as NATURAL VENEER, FINISHING FOIL or PVC FOIL in a separate process to the side and top of the door frame body to break down the overall production cost. The manufacturing method and the door frame of the door frame with lapping material which is manufactured by a simple process are reduced.

In general, the door frame was manufactured and used by a method of painting a color on a Rawang window. However, as the quality of life improves, the number of people who want to decorate the interior with wood is decreasing the demand for colored painted windows. However, the price of timber is not only very expensive compared to the Rawang window, but there is a drawback of lack of unity due to the warpage or warping phenomenon and the color and texture of the wood.

WRAPPING PRODUCTS was developed to solve the problems of the colored paints Rawang and wood windows mentioned above. Wrapping products cover various windows and materials such as PVC FOIL, FINISHING FOIL, NATURAL VENEER, etc., and have long been used in Europe.

Figure 1 is an exploded perspective view of a conventional wrapping door frame, Figure 2 is an assembled cross-sectional view of Figure 1, Figure 3 is an enlarged view of the body frame portion of FIG.

As shown, the conventional lapping door frame door frame body 15 and the door stopper (Door Stopper, 10) to install the door frame 13 at the time of construction of the wall 11 and then securely fix it with the door frame body without difficulty. It is composed by separating.

Lapping is made to the protrusions and the door stopper 10 of the door frame body using the lapping neck 17. At this time, since the groove 18 to be inserted into the door stopper part should be dug into the door frame body and the lapping material should be adhered to the outside, the material to be used for the door frame body 15 is made of high quality Rawang composite wood or MDF suitable for the process. Material is required.

Hereinafter, the manufacturing process of the above-mentioned door frame will be described.

The size of the door frame body 15 and the door stopper 10 is determined according to the thickness of the wall 11 at each site, and after preparing expensive materials such as Rawang Aggregate or MDF larger than required dimensions, suitable for molding each After the molding is completed by processing a regular dimension in a processing machine (Moulder), the wrapping material such as natural veneer is wrapped on the necessary part, and in the case of natural veneer, it is completed through a grinding and painting process.

By the way, the door frame body made by the door frame manufacturing process is not only economical, but also uneconomical by using relatively expensive materials such as laminated wood and MDF, even though only the round processing of the corner is required without special shape processing Since the grooves are prepared after the material is prepared with a margin for processing, the cost of the material itself and the losses incurred during machining are inevitable.

In addition, it is impossible to standardize because the desired standard is different for each site. Therefore, the cutting blade of the desired dimension must be prepared in accordance with the processing dimension of the material, and the setting work of the blade must be done again according to each dimension. The work is cumbersome and time consuming, and there is a problem in that overproduction, which is frequently produced during production on a site, must be held as a bad stock.

Therefore, the present invention has been made to solve the above problems, using a relatively inexpensive raw material on the inside, using a relatively high-grade material on the outside to improve the overall quality of the advanced material, simplify the manufacturing process, possible parts The purpose of the present invention is to provide a method of manufacturing a door frame with a wrapping material that enables mass production and reduces costs through standardization and standardization.

Another object of the present invention is to provide a door frame with a wrapping material that can use relatively inexpensive raw materials, simplify the manufacturing process, enable mass production through standardization and standardization where possible, and reduce costs. It is.

It is configured to such a degree.

The side coupling material 220 is installed on both sides of the body material 210 to block the side portion of the body material 210 from the outside and at the same time the surface of the low-cost raw material of the body material 210 is exposed to the outside Prevent it.

The side coupling material 220 is formed and cut to have a width and a length corresponding to the side surface of the body material 210. Since the thickness of the body material 210 is standardized and usually has a constant thickness and length, the side bonding material 220 is also cut to a standardized size according to the thickness and length of the body material 210. As the material of the side coupling material 220, MDF, plywood, or HDF is used. Here, the material of the side coupling material 220 is generally the same material as the material of the bottom layer 211 and the top layer 213 in consideration of the shrinkage expansion rate of the body material 210, the door frame 200 This is to prevent surface drift that occurs after a certain period of time after installation on site.

Bonding of the lapping material 240 is a lapping method using a lapping machine is used and the upper surface of the body material 210 except for the stopper coupling groove 216 which will be described later and the outer surface of the side coupling material 220 Squeezed. Here, the wrapping material 240 is made of natural veneer (NATURAL VENEER), pattern paper (FINISHING FOIL OR PAPER POIL), vinyl sheet paper (PVC FOIL) and the like. Since the wrapping material 240 is a known technique, detailed description thereof will be omitted.

If necessary, the side groove 221 is formed on the side surface of the side coupling material 220 to which the wrapping material 240 is attached, and the L-shaped door line 250 is inserted into and fixed to the side groove 221. By adjusting the width of the upper portion of the 250 in various ways to adjust the side length and the top surface length of the L-shaped door line 250 so as to correspond to the thickness of the wall 100 to cut the main body material 210 in contact with the wall Since it contacts the mold 110, regardless of the thickness of the wall 100 can be standardized in the size of the body material 210, and also standardizes the size of the side coupling material 220.

The upper surface of the main body material 210 to which the side coupling material 220 is attached is formed with a stopper coupling groove 216 in which a stopper 230 to be described later is installed.

The stopper coupling groove 216 has a shape recessed downward from the upper surface of the body material 210 and is configured to have a predetermined width and is formed to be connected in the longitudinal direction so that the coupling protrusion 231 of the stopper 230 described later is formed. The body material 210 and the stopper 230 are coupled to the stopper coupling groove 216.

The stopper 230 is formed in a plate shape having a predetermined width and thickness, and is formed on the lower surface of the stopper 230 by a predetermined protrusion downwardly connected to the lengthwise coupling portion 231. And the wrapping material 240 formed integrally on the side and the top surface of the stopper 230 is wrapped.

The shape of the door frame 200 is completed by inserting the coupling protrusion 231 of the stopper 230 into the stopper coupling groove 216 formed on the upper surface of the body material 210. Here, when the stopper 230 is coupled to the upper surface of the main body material 210, the upper surface of the stopper 230 protrudes to a predetermined upper side than the upper surface of the main body material 210, the door (not shown) When closed, the door is caught by the side of the protrusion 232, the flow of the door is stopped and the door is closed.

The door frame 200 has been described above. Hereinafter, the manufacturing method of the door frame 200 will be described.

The method of manufacturing a door frame with lapping material according to the present invention is largely divided into five steps.

The first step is to form the body material 210, the body material 210 can be configured in two ways.

First, the body material 210 is composed of three layers. Body material 210 composed of three layers is composed of the bottom layer 211, the intermediate layer 212 and the upper surface layer 213. The bottom layer 211 and the top layer 213 have a thickness of about 2.7 to 3mm, and is made of MDF material. The intermediate layer 212 has a thickness of about 10 to 30 mm and is made of Albizia material. The intermediate layer 212 is brought into close contact with the bottom layer 211, the upper layer 213 is brought into close contact with the upper surface of the intermediate layer 212, and pressed and pressed to bond three layers, and then cut into a predetermined size to form a main body material ( 210 is formed.

Second, the body material 210 is composed of five layers. The main body material 210 formed of five layers includes a bottom layer 211, a first core layer 214, an intermediate layer 212, a second core layer 215, and an upper surface layer 213. The bottom layer 211, the first core layer 214, the second core layer 215, and the upper surface layer 213 have a thickness of about 1.2 mm. The intermediate layer 212 has a thickness of about 10 to 30 mm. When the respective layers are prepared, the bottom layer 211, the first core layer 214, the intermediate layer 212, the second core layer 215, and the upper surface layer 123 are stacked in order from the bottom side, and then pressurized. The main material 210 is formed by pressing and bonding the five layers to cut a predetermined size.

Next is a step of pressing and pressing the side coupling material 220 coupled to both sides of the body material 210 in the second step to both sides of the body material using an edge bander (EDGE BANDER). The side coupling material 220 is manufactured to have a thickness and a length corresponding to the side portion of the body material 210. Since the standard of the body material 210 is standardized, the standard of the side coupling material 220 is also standardized, and the material of the side coupling material 220 is the bottom layer of the body material 210 in consideration of the shrinkage expansion rate. It is made of the same material as the 211 and the upper surface layer 213.

When the side coupling material 220 is prepared, the side coupling material 220 is pressed to both sides of the body material 210. The pressing is carried out using an edge bander (EDGE BANDER).

Next, a third step of forming a stopper coupling groove 216 in the main body material 210 and rounding the corners of the side coupling material 220 bonded to the side of the main body material 210 is performed. The stopper coupling groove 216 is formed by digging in the longitudinal direction by using a molder to have a predetermined depth and width downward on the upper surface of the body material 210. And the corner portion of the side bonding material 210 is a rounding process is performed to wrap the wrapping material 240 well.

After the third step is performed, a fourth step of adhering the wrapping material 240 to the upper surface of the body material 210 to which the side bonding material 220 is bonded and the side bonding material 220 is performed. Bonding of the wrapping material 240 is carried out using a wrapping machine. Since the lapping is a known technique, detailed description thereof will be omitted.

Next, a fifth step of forming the stopper 230 for blocking the door is performed. The stopper 230 is cut into a shape having a predetermined size having a predetermined thickness, and the wrapping material 240 having an approximately "c" shape integrally formed on the top and side surfaces of the stopper 230 is wrapped. In addition, a lower surface of the stopper 230 is formed with a coupling protrusion 231 inserted into and coupled to the stopper coupling groove 216 of the body material 210, so that the coupling protrusion 231 is coupled to the stopper of the body material 210. The door frame 200 is completed when the body material 210 and the stopper 230 are coupled to the groove 216. When the completed door frame 200 contacts the door frame 110 and the doors are coupled, a set of door structures are completed.

In the above configuration, in particular, when using the L-shaped door line 250, when the thickness of the wall 100 is different from the actual construction due to the plastering error, it is impossible to adjust the standard of the body material 210, but a defect occurs. In the present invention, the body material 210 may be installed to correspond to the thickness of the wall by the gap between the depth of the side groove 221 formed in the side coupling material 220 and the insertion part 222 of the L-shaped door line 250. Can be.

According to the present invention, the main body material is formed by laminating three or more layers of the main body material with different materials, and using the low cost raw material for the inner part and the expensive raw material for the outer part to construct the main body material. Overall, the texture of high-quality materials, but at a cost cost is quite effective.

In addition, there is also an effect that the mass production is possible by standardizing the body material and the side bonding material.
