A machine for manufacturing of oval duct

FIELD OF THE INVENTION The present invention relates to a machine for making ovaldact.

In detail, the seam welder which can weld the center part continuously in the state which overlapped the ovaldact material is installed, and the ovaldact material which passed this seam welder has the upper part of the chain on the roller. When the tip of the stopper comes into contact with the stopper as it slides, when the ovaldact material touches the stopper, the ovaldact material is cut to a certain length by a cutter, and the cut ovaldact material changes the chain that is moved by each cylinder. The bent shape is bent in the same way as the mold shape, and the Ovaldact material maintains the same shape as the mold shape by plastic deformation even if the chain is returned to the roller by the operation of each cylinder. In this way, it is possible to automatically manufacture the ovaldact according to the shape of various ovaldacts. The present invention relates to a machine for manufacturing an ovaldact, which enables the prevention of a decrease in the production efficiency according to the manufacturing process depending on the work and the productivity improvement due to the production automation.

Looking at the prior art, by the manual method to manufacture the shape of the ovaldact or by using a simple manual manufacturing machine to proceed to separate operations one by one for each process, there is a problem of decrease in work efficiency and productivity In addition, the problem of reduced product competitiveness due to quality deterioration has emerged as a problem.

The Korean Utility Model Publication No. 1996-001 001 manufactures a straight ovaldact with the circular duct extending through the ovaldact manufacturing apparatus and expanding the ovalact whose shape is changed in the longitudinal axis direction, while the upper and lower sides of the uniaxial direction remain changed in a straight line. The present invention relates to a device for manufacturing a straight oval duct, in which an expansion force is applied to both sides of a circular duct so that a straight portion on the upper and lower sides of the circumferential direction is maximized, and the height of the axial axis is lowered within the usable range to further lower its strength and brace. A device for manufacturing a straight oval duct that can be raised. The front of the main body with a control box is welded and fixed with a slider guide groove with a slider guide groove inwardly, and a slider is inserted into the slider guide groove. Between the piston rod and the fastening pin, The stepped end of the abutment is inserted into the guide groove of the guide plate attached to the main body so that the fixed and moving parts are closest to each other. It is a device characterized in that the movement between the opening and closing as the slider moves forward and backward to lower the minimum,

The Korean Utility Model Publication No. 95-16961 is a molding apparatus used in the intermediate process for changing the cross section shape of a circular duct and finally producing it as a straight oval duct, and molding the cross section of the circular duct into an oval duct. In order to make the duct expand smoothly without overloading the machine during the final stage of straight ovaldact,

The present invention relates to a manufacturing technique for intermediate processes that must be performed separately according to each process in the manufacture of the ovaldact, the manufacturing method according to the change of the shape of the ovaldact is a manual method or to manufacture an accurate shape There is a problem that cannot be solved.

The present invention to solve the above problems,

As the material of Ovaldact is put into the machine for manufacturing Ovaldact and the machine is operated, various shapes of Ovaldact can be automatically produced by simple replacement and replacement of the mold, and the shape can be produced exactly according to the mold. It is a machine for manufacturing an oval duct, and it is possible to automatically produce products of easy and accurate shape and quality depending on the application of molds even if the duct of various shapes is manufactured in the ovaldact, increasing product productivity, manufacturing efficiency and quality The aim is to improve the
