The present invention relates to a window frame manufacturing apparatus, and in particular, to easily bend in a variety of shapes and sizes by using a pinch roll set and a forming roll set of the v-cut steel coil and panel to improve the convenience and economics of window frame production It is related with the window frame manufacturing apparatus characterized by the above-mentioned.

In general, the insulation window has a heat insulation function and a sound insulation function, and is mainly used in general houses and apartment houses, offices, etc. The material is aluminum or PVC, and the composition is hinged to the window frame and the window frame fixed to the wall It consists of a window frame.

On the other hand, stainless steel plate for building the insulation window is standardized to 3m or 4m in length 1m in width and sold on the market. However, in general, the height of the shop window on the first floor of the mall is about 2.6m to 2.7m. Thus, expensive stainless 3m boards are cut to 2.7m or less, and discarded residues longer than 30cm are disposed of as scrap metal. Since the width is 1m, it is necessary to cut (cut) the window frame to produce a lot of residue and fragrance, which is a big cause of cost increase and resource waste.

In addition, the bending process by pressing the V-cutting place with the blade of the bending machine in order to adjust the angle required, depending on the frame to replace the bending machine blades in order to complete the frame by inverting the plate. In addition, the defect rate and the product quality of the product is different according to the skills of skilled workers, and the above problems, but the processing method of the window frame is only the bending method by the conventional bending machine.

In addition, the existing window frame of the existing bending machine is vulnerable to soundproofing, windproof and dust. Especially, due to its low thermal insulation, energy loss is high in cooling and heating. Thus, the reinforcement oil redoor has moheya grooves for soundproof windshields in the upper and lower H bars (a stainless steel frame that protects the glass by inserting it at the top and under the tempered glass and attaches and secures the loto lot). There was a product, but there was a gap between the stainless steel frame and the tempered glass door, so dust and wind came in and tried to fix it by sticking the wind paper or tape, but the appearance was not good and practical.

The present invention is to solve the above problems, and provided with a pinch roll set and a forming roll set that can freely move the plate of the window frame, by selectively applying a physical pressure to the bending portion of the product, and with a more convenient production Its purpose is to increase economics.
