Abstract
Description
The present invention relates to a slim square duct manufacturing apparatus, and more specifically, through a plurality of straightening rollers are continuously installed plate material supplied from the composite reel is formed by a shearing groove is formed on the outer surface and the length of the plate material Slim square duct which makes the manufacturing of the slim square duct mechanically by a series of processes in which the length of the plate is cut to the desired dimension and is firstly bent at both ends through the bending rollers and joined at both ends after the second bending. It relates to a manufacturing apparatus.
In general, the duct is installed on the ceiling of the building to provide a ventilator to facilitate the ventilation of the room, which represents a passage for discharging indoor air or supplying fresh air to the inside of the building. Thin iron plate was formed in a round or square shape, but it was manufactured to a certain length in order to facilitate transportation and installation, and then cut and installed according to the installation position at the installation place.
Conventional square and circular ducts are fixedly installed in the interior of the building, especially the ceiling, the ducts have a constant diameter has a problem that acts as an important factor to determine the height of the beam of the building to bring spatial constraints. For example, in the case of a new building, it is not a big problem to design in consideration of the height of the room in consideration of the diameter of the duct, but the height of the ceiling because the existing building is constructed by lowering the height of the beam without considering it. In addition, a wider diameter duct having a sufficient ventilation capacity is lowered and a smaller diameter must be used. Therefore, a lack of indoor ventilation has caused a lot of harm to the human body.
Recently, in order to solve the above problems, there is an increasing number of constructions that require replacement of conventional rectangular ducts and circular ducts with slim square ducts having a smooth and refined aesthetics with less heat loss and friction loss.
However, in the conventional Oval duct manufacturing technology, the process of manufacturing the shape of the Oval duct is performed manually by a manual method or by using a simple manual manufacturing machine, which is performed separately for each process, one by one, to reduce work efficiency and productivity. There are problems of deterioration and the problem of reduced product competitiveness due to quality deterioration.
Korean Utility Model Publication No. 1996-0001805 manufactures a straight oval duct in which the circular duct passes through an oval duct manufacturing device and expands the oval duct whose shape is changed in the longitudinal axis direction so that the upper and lower sides of the short axis direction remain changed in a straight line. The Korean Utility Model Publication No. 95-16961 is a molding apparatus used in an intermediate process for changing the cross-sectional shape of a circular duct and finally manufacturing it as a straight oval duct. The present invention is to compress and expand the circular duct manufactured by forming an oval duct to ellipse so as not to overload the machine and smoothly inflate the duct during the final stage of manufacturing the straight oval duct. The process of changing the shape in addition to the manufacturing process of the duct The manufacturing process is increased as being added to the manufacturing method increases the manufacturing cost and due to the shape change of the misfire in the duct of round duct has a problem in that the correct shape can be manufactured. In addition, in the method of manufacturing the oval duct by applying pressure to the circular duct, when attempting to manufacture an oval duct of a different length from the previously manufactured oval duct, the pressure to be applied must be newly set. There is a problem that it is difficult to fit and therefore it is difficult to manufacture the oval ducts of various specifications as a single device.
The present invention has been made in order to solve the above problems, the present invention is molded by a continuous roller shape and the joint portion is joined by bending and pressing by a continuous roller and by applying a resin (synthetic resin) just before joining It is bonded to prevent leakage and is discharged while maintaining its shape by roller, and by manufacturing a slim square duct by a series of processes to provide a slim square duct manufacturing apparatus that mass production of slim square duct products of accurate shape and quality quickly For the purpose of
