Description

MULTI TYPE FORMING MACHINE}

According to the present invention, a plurality of roller modules having different forming specifications in a single device are arranged in a height direction, and the height of the roller module of the corresponding specification can be easily lifted and adjusted to a worktable position so that various shapes and specifications of various specifications can be formed in a single device. Compared to the technology, the present invention relates to a multi-form forming machine that dramatically reduces the footprint and significantly increases the space utilization.

Steel fire doors, which are used as apartment doors or entrance doors to building offices, have a variety of specifications, such as one-door doors and two doors that open on two sides, depending on the building. Each is separately formed and manufactured by bonding to each other.

The production of such fire doors includes a cutting process of cutting the steel plate into a predetermined shape, a press drilling process of forming door lock insertion holes, a lock and a hinge hole, a bending forming process of joining the inner and outer plates to the edges of the steel plate, and It comprises a step of attaching and assembling the inner plate and the outer plate and the inner filling honeycomb.

1 is a cross-sectional view of the general specification showing the foaming configuration of the fire door and the outer and inner plates of the cross-sectional view, a part of the separation diagram is also shown upside down to facilitate identification.

As shown in Figure 1, the fire door is not only different from each other in the dimensions and the forming shape of the inner plate and the outer plate, but also depends on the specifications, both of which are formed on both sides of the plate when viewed on a single plate material.

The closed type is a first specification, as shown in FIG. 1A, the two forming joints are located on a diagonal line.

However, the first specification 100 has a problem in that workability is reduced because the outer plate 110 is larger in length than the outer plate 110 and the inner plate 120 have different sizes. Therefore, in recent years, the second type of the closed type specification 200 as shown in FIG. 1 b to unify the standard of the inner plate and the outer plate has been widely adopted (reference numeral '210' is the outer plate, '220' Is internal).

In addition, the two expressions are installed in the left door and the right door when viewed from the inside as shown in Figure c of Figure 1, the left door is the same as the form of the first specification or the second specification returned, the right door is the As a specification and another third specification 300, both junctions are located forward (reference numeral '310' is outer plate and '320' is inner plate).

In addition to such a configuration, there are various specifications such as a round shape in which the edges of the doors are rounded, and various specifications are formed in the same specification.

Such bending forming of the fire door is performed through the forming machine 100 which is gradually formed into a desired shape while passing between the plurality of forming rollers 111a as shown in FIG. 2.

However, the prior art has a problem that the productivity is very low and the inventory is accumulated by adding the process of loading and transporting the plate material by combining each of the inner plate inner plate in a different working position and then combined with each other.

As an alternative to this problem, the applicant has proposed a patent application No. 2005-102321 (former name "former system of universal specification fire door") (hereinafter referred to as "pre-applied technology").

3 is a configuration in which a plurality of forming machines 100 are disposed inward so that the plate material is formed in a plurality of specifications on the left and right sides of the transfer table 7, as shown in FIG. 3. Each one of the left and right forming parts of the plate material is first formed in one of the plate material left and right forming machine 100 is moved to the delivery direction to form the other one side of the transfer table (7) Excreted from side to side.

And the transfer table 7 is installed divided into both sides of the worker movement path (115).

According to this configuration, the plate material movement in the forming process is semi-automatic, in which the worker pushes the plate material placed on the transfer table 7 to the guide wall 117 provided in the forming machine inlet in the moving passage 115. It is made in a manner, the operation of each forming machine 100 is selectively controlled by the control unit according to the specification of the inner plate or outer plate of the plate material to be processed.

Therefore, the worker pushes the plate material only in the left and right direction without flipping or lifting the plate material, and the forming of the inner and outer plates of various specifications is alternately performed to prevent the occurrence of inventory, and the work flow is efficient, which saves manpower and time. There is a benefit.

In addition, by forming a variety of specifications in one manufacturing line, the occupied area of the device is reduced compared to the prior art, there are various advantages, such as to increase the space utilization of the factory.

However, the applicant has been steadily researching and developing such a fire door manufacturing system, while the above-mentioned application technology significantly reduces the occupied area compared to the prior art, but the forming machine of each specification is arranged in a long line on both sides of the transfer table. And it has been found that the length of the transfer table line is long, and the plant area must be secured largely.

The present invention has been made to solve the above problems,

It is an object of the present invention that a plurality of roller modules having different forming specifications in a single device is disposed in the height direction and the height of the roller module of the corresponding specification can be easily lifted and adjusted to the worktable position to form shapes and specifications of various specifications in a single device. Therefore, the present invention provides a multi-form forming machine that significantly reduces the occupied area and significantly increases the space utilization as compared to the prior art.

It is another object of the present invention to provide a multi-spec forming machine that reduces the length of a worker's copper wire and a transfer table line, thereby reducing facility cost and manpower and significantly increasing productivity.
