Abstract

PROBLEM TO BE SOLVED: To obtain a stamping die for forming a metal siding enabling to correspond to a variety of plate widths in stamping dies capable of continuous forming. SOLUTION: A plate width guide 11 enabling to put on and take off is arranged. An upper die is constructed with a die for a pattern portion to form an embossed pattern and a joint portion, and also a holding portion for stamping ear 5(a) and 5(b). A lower die 8 is constructed with a urethane rubber 10, a latticed die to form the joint portion, and the holding portion for stamping ear 5(a) and 5(b). A guidepost 14 is also arranged to protect out of position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a press die capable of efficiently producing metal siding by continuous pressing.

[0002]

2. Description of the Related Art Conventionally, molding by roll embossing has been performed on a material having a simple shape or pattern. The application to metal siding has also been limited to simple shapes.

[0003]

However, in recent years,
With respect to metal siding, the demand for so-called high-design metal siding having deep patterns and joints and having a relatively complicated shape having a fitting portion so as to facilitate processing and assembly has been increasing. In manufacturing such a metal siding product, if the press dies are replaced for different shapes and dimensions, the manufacturing process becomes complicated.

[0004] For example, metal siding includes general materials and fireproof materials. The difference between the two is that the fireproof material must be increased in thickness (depth) in order to fill with heat insulating material or aggregate. There is no essential difference in the pattern, shape, etc., only. However, because the difference in the thickness causes a difference in the board width of the portion where the fitting portion is formed before forming, each embossing roll is required. For this reason, the manufacturing cost is increased, and in the forming process, a roll replacement operation is required, which is troublesome.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a press die capable of continuously forming a metal siding having a pattern portion, a joint portion, and a fitting portion on a metal plate. A metal siding molding press die characterized by being able to cope with a width. Specifically, only when molding a general material having a narrow plate width of the fitting portion, by providing a plate width guide, it is possible to form a general material and a fireproof material with a single mold. It is a feature.

[0006]

Embodiments of the present invention will be described below. FIG. 1 shows a cross-sectional view of the press die of the present invention. The press die 1 has a structure of an upper die 3 and a lower die 8, and is provided with a guide post 14 as a measure for preventing displacement.

FIG. 2 shows an upper die of the press die according to the present invention. The upper mold 3 includes a pattern mold 2 for molding the embossed pattern 4 and the joint 16, a wrinkle holding portion for forming a fitting portion, and a front plate on the material entry side for preventing wrinkles during molding. It is composed of a pressing portion 6 and a rear plate pressing portion 7 on the material exit side for preventing breakage due to jumping up. The wrinkle holding part of the part to be molded is cut 12 at the same position as the plate width guide 11 provided on the lower die 8 on the wide male side 5 (a) and the narrow female side 5 (b). It was done.

FIG. 3 shows a lower mold of the present invention. The lower die 8 includes wrinkle pressing portions 5 (a) and 5 (b), which are formed at the same position as the pattern processed at the same position as the pattern portion die 2 of the upper die 3, and the front pressing portion 6 and the rear pressing portion. It consists of part 7. Pattern type 2
Are a urethane rubber 10 for forming an embossed pattern and a lattice-shaped mold 9 for forming joints. The board width guide 11 is provided on the wrinkle holding portion male side 5 (a) and female side 5
(B). Further, a backup 17 is provided to prevent the wrinkle holding portion of the fitting portion formed at the time of pressing from bending. The mold is also provided with a plunger 13 for facilitating dispensing of the material after press molding.

[0009]

According to the present invention, it is not necessary to use a mold for both a general metal siding material and a fireproof material. Thereby, the mold cost is low, and both can be formed only by attaching and detaching the plate width guide.
