Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stamping tool and a method of using the same in the production of continuous strip roofing tiles from flat metal sheets.

Long, continuous roofing materials are widely used today, and this type of roofing material is known to have advantages over other roofing materials. The main advantage of strip roofing materials is that they can be made and placed more economically than, for example, single tiles or shingles made of concrete or other materials. Although the aesthetic appeal of this type of material may not be to everyone's taste, there is a growing demand for materials that have the appearance of being made up of many individual tiles or shingles, even strips. The manufacture of such boards presents the problem of having to make numerous bends in the material within a relatively small area in order to create slag in the board. Materials that have been sludged out using these methods have had the problem of localized elongation and stress concentration throughout the material, resulting in continued brittleness.

According to the invention, a molding tool is provided for forming a slag on a piece of material that extends longitudinally and laterally and consists of first and second molding members cooperating with each other. Each of the mold members is formed as a unitary structure and has a length equal to the length of at least one major surface plus the length of the tile step on which the slag has been applied. a step section, a second section having a surface substantially parallel to the surface of the first section; There is decoration, and the surface of the step part is also decorated, and the first part and second part of one mold member and the surface of the step part are similar to the first part, second part, and step part of the other mold member. On the other hand, the material pieces complement each other and the first member and the second member of the molding tool
It is effective in making the tile pattern appear on the material pieces when it is cut between the parts.

Such a stamping tool seeks to solve the aforementioned problems that arise when producing slag roofing materials and/or sludge coating materials.

The invention also seeks to provide a method for forming a longitudinally and laterally extending slag in a piece of material, which method comprises providing a molding tool according to the invention and moving the piece of material into a mold member. The advancing portion of the piece of material Q is advanced between oppositely disposed complementary surfaces, closing together the two mold members of the molding tool, and between said mold members, the final portion of the slag extending at least in the longitudinal direction is It consists of a process force that determines deformation and forms steps in a piece of material.

The piece of material is preferably flattened from the beginning. The method also includes the step of 1 preforming most of the deformation necessary to produce the longitudinally extending slag by feeding the material between the preform rolls. Therefore, only the final deformation of the material piece to produce the longitudinally extending slag is carried out by the mold part of the molding tool.

Alternatively, a longitudinally extending slag can be formed simply by closing the two mold parts together.

The details of the invention will be explained with reference to the drawings related to the embodiments.

In Figures 1 and 1a, two examples of roofing materials manufactured over their entire length from flat pieces of material such as galvanized iron or aluminum are shown. The piece of material has a plurality of slag extrusions formed by cold working. For a piece of material of this kind, longitudinal and transverse extrusions are formed on it, so that although it is a strip (1), the finished product consists of a number of individual pieces as indicated by arrows (1). The shingles or roof tiles are exposed to slag. The tile slag 1 consists of a main surface 2 and a stepped portion 3 of the tile. The main surface 2 and/or the step 5 of the tile floating skewer 1 has a decorative edge or a decorative corrugation formed therein.

FIG. 2 shows a typical die configuration known in the art for extruding slag 1 from a flat piece of material 5. FIG. The complementary parts 6a, 6"b of the molding tool are formed with opposing surfaces 7a, 7b with complementary decorative surface contours and/or patterns adapted to produce the desired slag 1 on the piece of material. .

In known manufacturing methods, the lower part 6b of the molding tool is usually fixed, and the upper part 6a of the molding tool is fixed.
b is made to move up and down in the direction perpendicular to b, during which the slag 1 is stamped into the piece of material 5, and the piece of material advances periodically, so that the rows of slag 1 Upper part 6a1
It is formed when the lower parts 6b are brought together and the pieces of material are sandwiched therebetween. This manufacturing method is carried out in one operation and therefore many stress concentrations are created in this stamped piece of material 5, the most significant being in the area 9 of the piece of material 5 near the step 3. It is in 10. ,.

6 and 4: the upper and lower mold members 11a, 11b each have a major surface, here a first portion 12, which is similar in all respects to the mold tool known and shown in FIG. A set of molding tools of the present invention is shown. However, for a long time, the mold part consisted of only one decorative step 16 and a second
It has a lower part 14.

Further, referring to FIG. 4, in the known stamping tool shown in FIG. The first portion 12 of the molding tool of the invention is substantially longer than that of known molding tools. That is, the length L in FIG. 4 is made twice to three times the length of the main surface 2 of the tile slag 1 stamped from the upper and lower mold members 11a and 11b of the present invention, and the complementary portion 6a
.

The length Ll of the second surface 14 below the main surface 12 of 6b is shorter than the length of the main surface 2 of the stamped tile slag.

The length of the stepped portions 13 of the upper and lower die members 11a, 11b is approximately equal to the length of the stepped portion of the tile slag to be stamped.

Main surfaces 12 and step portions 1.6 of upper and lower mold members 11a and 11b
and the second surface 14 can be fabricated from steel or metal and has the desired properties of being durable and resilient enough to suppress pre-coated material without damaging the electroplated or painted surface. Lurisan
) is covered with a plastic material covering.

From FIG. 5(1) to the fifth panel, steps are shown during the production of a stamped piece of material at the station where the die member of the stamping tool is positioned. The method begins with the step illustrated by FIG. 5(1). In this step 1, the end 5a of the piece of material 5 is fed between the first parts 12 of the mold members 11a, 11b, and its free end stops before the step 13 of the mold members. The mold parts 11a, 11b are then closed, so that the ends 5a of the material pieces are preformed and give the final product a generally longitudinal surface decoration.

In the fifth (++) illustrated step, the mold members 11a, 11b are opened and the piece of material is then advanced by a predetermined distance, the ends of the preformed piece of material being here shown in dotted lines.

The mold members 11a, 11b are brought together to sandwich the piece of material therebetween, forming a first step 5a on the piece of material, and abutting the edge 5a of the previously flattened piece of material. Another part 5C is preformed.

In the illustrated process, the mold members 11a and 11b are open, and the material piece is formed so that the length of the main surface 2 of the tile slag to be stamped is equal to the length and depth of the step 6). Move forward by a distance equal to the object.

In the step shown in the fifth screen, the mold members 11a, 11b are brought together again, so that the first complete slag 1
is completed and subsequent steps are repeated without restriction.

If the step is preformed before being stamped into the piece of material, the length of the main surface plus the length and depth of the tile step is at least equal to the length and depth of the tile step in the final product. It has been found that there is a substantial reduction in the vulnerable stress area.

FIG. 6 schematically shows an apparatus for carrying out the steps described above. The device comprises a source 15 of pieces of material being rolled into position I, a set of feed rollers 1''''6'' at position 1, and an upper reciprocating machine on which mold members 11 are attached. Press 1 at position l, consisting of head part 18 and lower fixed part 19 to which mold member 11b is attached
7.

A pair of shears 26 or other cutting means are placed at position (2), and the stacking table 21 and the like are placed at position (2).

The delivery of the material pieces 5 from the roll-shaped supply source 15 is controlled by a geared material indexing mechanism or other indexing mechanism in conjunction with the supply roller 16, and which indexing mechanism has the mold member 11a attached thereto. The reciprocating motion of the reciprocating head section 18 and the shearing machine 20 are synchronized.

The longitudinal decoration of the main surface is carried out entirely by the molding elements of the molding tool, as shown. If necessary, the feed roller 16 closer to the presses 1, 7 can be moved at least 1
As shown in 6, it is also possible to apply most of the decoration extending in the longitudinal direction by carving.

Final decoration can also be applied by means of mold members.
