Description
The present invention The present invention relates to a manufacturing method of a mold frame for manufacturing a fire door door frame having a double sealed structure, and more particularly, to provide a fire door door frame that can be easily assembled by sequentially bending a metal plate without being limited by the length of the metal plate. The present invention relates to a manufacturing method of a mold for manufacturing a fire door door frame having a closed structure.
In general, due to the increase in large-scale residential buildings such as apartments and shopping malls, fire doors are mainly used to block living spaces from outside and protect internal residents from fires.
And in order to install the fire doors, a door frame frame supporting the fire doors is necessary.
In the case of the lower door frame frame that supports the lower part of the fire door among the door frames of the fire door, the heavy weight such as a person passes from the outside to the inside or from the inside to the outside, so it is not only rigid but also not easily deformed by external impact, It should not be sludged, and the weight should be able to be easily moved in and out of the undercarriage, and should be constructed so that certain protrusions are formed to completely seal the door.
However, when looking at the mold for manufacturing such a door frame frame, there is a problem that the packing member is inserted to hold the outside and the inside of the inside tightly fixed and fixed.
In order to solve the above problems, the mold of Patent Registration No. 10-0347551 is provided, and the mold mold has been firmly held by the packing member to maintain the outside and the inside, but can be manufactured only when the length of the metal plate for manufacturing is limited. There is a problem that is difficult to manufacture, and because of this, only a part was processed and another part had to be processed separately and welded.
As a result of this problem, when the weight passes through the door frame for supporting the fire door, the door frame is damaged and deformed for load, and the cost of repairing and replacing the door frame is doubled.
The present invention has been made in order to solve the above problems, the object of the present invention is to be able to manufacture a variety of door frames of various shapes without being limited to the length of the metal plate.
In addition, the purpose is to provide a door frame easy to assemble through the sequential bending of the metal plate.
In order to achieve the above object, in the mold for manufacturing a fire door door frame, a punch press having a symmetrically inclined surface is provided on the upper surface of the punch press, and a lower surface of the punch press corresponds to the punch processing protrusion. The upper auxiliary mold is formed in the upper groove and the upper groove is installed on the upper mounting groove and the upper surface is provided with the upper mold is formed with the upper bending surface having different inclined surface, the lower portion of the upper mold corresponding to the upper bending surface Intermediate mold in which the fitting coupling groove is recessed is installed on the inner inclined surface while having the inclined groove, and installs the intermediate mold mounted on the intermediate mounting groove, and in the lower portion of the intermediate mold, the fitting protrusion protrudes upward on the bottom. Including the lower mold is formed in the lower receiving groove formed on the upper It provides a manufacturing method to be made.
According to the present invention, since the door frame of various shapes can be integrally manufactured without being limited by the length of the metal plate, there is an effect of reducing the cost and the time required for the work.
In addition, through the sequential bending of the metal plate can not only provide a simple door frame assembly, but also has the effect of mass production.
