Description

Fixing method and structure of a window pillar}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window pillar manufacturing process and structure thereof, and more particularly, to a process and structure for easily and easily fixing a vertical tube on a horizontal tube.

Conventionally used methods and structures are shown in Figures 1a, 1b, 1c, and 1d, when the vertical tube is fixed to the horizontal tube for supporting the window frame, firstly cutting the rectangular vertical tube and then cutting the incision groove. After forming, the mold is inserted into the incision and blows to widen the opening of the incision.

Then, the tapping plate is fixed to the upper side of the horizontal tube by welding, and the tapping plate is inserted into the inside of the vertical tube to be positioned to form a weld, and then welded. The tapping plate is fixed to prevent the opening of the incision groove opened by hitting the mold in the previous step, because many steps of welding must be performed, there are many processes because it requires a lot of precision.

The present invention has been proposed in order to solve the problems described above, and does not manufacture a vertical pillar portion of a window by using a rectangular tube, and an object of eliminating an intermediate process that causes a lot of complexity and tolerance by using a vertical member formed by a press. In addition, it has the purpose to provide high quality window pillars by improving welding efficiency and obtaining uniform welding quality by welding using continuous automatic welding machine without CO2 welding.

In order to achieve the above object, the present invention, in the window pillar manufacturing process for fixing the vertical member to the horizontal tube, by processing the steel plate to form a vertical portion in the shape of vertically cut the center of the square tube, the vertical Forming a vertical member having a horizontal tube attaching portion by forming the unit integrally with the lower portion and forming a wider width while descending downward; Vertical member welding step of forming a vertical member to face the vertical member to face each other and then welding with a continuous automatic welding machine; In the window pillar fixing method and the window pillar structure, characterized in that the horizontal tube welding portion of the welded vertical member by welding the horizontal tube attachment portion to the horizontal tube to form a weld portion, the square tube of the vertical cut shape The vertical portion and the vertical portion extends integrally, but the width becomes wider toward the bottom to weld a pair of vertical members forming a horizontal tube attachment portion with each other by a continuous automatic welding machine, and welds the horizontal tube attachment portion to the horizontal tube It provides a window pillar fixing structure.

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

First, as shown in Figure 2a to form a member for use in the portion corresponding to the conventional window pillar vertical tube is formed of a vertical member 10 by processing the iron plate by a press. The vertical member 10 is divided into a horizontal tube attachment portion 12 and a vertical portion 15 welded to a horizontal member. The vertical portion 15 is formed by cutting a rectangular tube in half, and attaching the horizontal tube. The portion 12 increases the width as the vertical portion descends to widen the portion in contact with the horizontal tube.

It is formed to be symmetrical with the vertical member 10 to form two vertical members (11) to be one set of pillars to face each other.

Then, the connecting portion of the pair of vertical members 10 and 11 is welded with a continuous automatic welding machine.

After that, the horizontal tube attachment portion 12 formed at the lower portion of the pair of vertical members 10 and 11 welded is fixed to the horizontal tube 21 by welding. As such, since only the weld part 20 is formed to fix the vertical member, the process reduces a lot of processes compared to the conventional method in which a lot of welding was performed by installing a tapping plate.

The present invention not only constructs the window pillar structure, which had to go through many processes as described above, in a simple and reduced process, but also uses a continuous automatic welding machine instead of carbon dioxide welding, so the notch effect by carbon dioxide pitch welding is achieved. Reduction, increased welding efficiency, and secured welding reliability have an excellent effect on strength.
