JPS58343A - Forming device for slat with rib pattern or rugged pattern for shutter - Google Patents

Abstract

PURPOSE:To obtian the titled forming device which forms a slat directly of a finished painted steel plate, by incorporating plural forming rolls and a forming roll, worked in such a way that a rib or pattern rugged pattern is formed on a slat surface, in a roll forming device. CONSTITUTION:In a forming device consisting of a known main roll group, forming rolls for a rib 3 and a forming roll for a rib pattern or unevenness pattern 4 are incorporated. To form both the rib 3 and the pattern 4, both rolls are used. To form only the rib 3 or pattern 4, one roll which is not in use is lifted and put off a pass line. During this period, a slat only slides on the lower roll, and causes no problem in roll formation. If the roll has unevenness, a difference in peripheral speed is generated and a beautiful surface is not obtained, so proportion parts having the pattern 4 are made to rotate. For this purpose, the main rolls are rotated only by frictional force by disengaging gears succeeding a driving source.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a roll forming device (roll forming device) comprising a plurality of forming rolls for forming a rib pattern (Fig. 4) or an uneven pattern (Fig. 5) on shutter slats. In the following description, the inlet and outlet portions of the molding device are also included in the "inside of the molding device"), and relate to a device for manufacturing slats with rib patterns or uneven patterns on the slat surface. .

To manufacture slats with ribbed or uneven patterns,
Embossed steel strips must be purchased from a steel manufacturer and then rolled into slats. According to this method, it is of course difficult to manually handle the copper strips with various patterns, but since the interlocking portions of the slats also have ribbed or uneven patterns, the slats are difficult to move when they are rolled up. The rotation was not carried out smoothly. In addition, the slats overlap each other due to the force applied to the winding drum, but this causes problems such as the slat surface rubbing and the coating peeling off, so for a long time, steel slats with ribbed or uneven patterns Not adopted.

In addition, galvanized steel sheets are processed with uneven patterns in groups 1 to 1. There are two types: one that uses paint baking, and the other that processes uneven patterns on the finished coated steel plate (color steel plate), but the latter is superior in quality, such as the adhesion of the paint film and the finish, compared to the former. ing. The present invention provides an inexpensive device that can directly form slats from finished coated steel sheets (colored steel sheets) belonging to the latter category, and at the same time form rib patterns and uneven patterns in the same process.

Shutter slats are generally formed using roll forming equipment. Each roll in such a forming apparatus is composed of an upper roll and a lower roll. The upper roll and the upper roll may each be of an integral type, or may be of a so-called split type, in which a plurality of parts are tightened and integrated. The split type has the advantage that it can be manufactured at a lower cost than the former.

As described above, the main roll of the upper and lower a-rolls is driven and connected to the support shaft of the lower roll, so that the upper roll can be adjusted upward. Further, the auxiliary roll is not driven, and is configured so that both the upper and lower rolls can be vertically separated from the pass line, and generally has a smaller diameter than the main roll.

Further, the forming apparatus is generally constructed with only such a main roll, or with an auxiliary roll interposed between the main rolls or at a position next to the final main roll.

An auxiliary roll in a roll forming apparatus is provided to assist the main roll in order to correct distortion during material forming or to prevent the flow of the material from shifting its center. If a roll forming device for forming a certain shape is insufficient in the number of stages when performing another forming, the roll forming process cannot be performed with the number of stages of the forming device. In this case, by appropriately disposing small-diameter auxiliary rolls between the main rolls, the number of stages can be increased and the same performance as a roll forming apparatus with several stages can be achieved.

The present invention uses a known roll forming apparatus, and has been modified so that it can perform not only the original slat forming process but also other processes, such as forming a lip pattern or uneven pattern on the slat surface. Embodiments will be described below with reference to the accompanying drawings.

1 to 3 show slats for shutters that can be molded within the molding apparatus according to the present invention. 1st @lad is a slat with a flat surface 2; 2nd figure 1b is a slat with two parallel lips 3, 3 continuous in the longitudinal direction (or laterally when incorporated into a shutter) on the surface; FIG. 3 shows a slat having a rib pattern (FIG. 4) or an uneven pattern (FIG. 5) 4 on its surface between the lips 3 in FIG. 2.

According to the present invention II-It, it is possible to form a wide variety of slats in a roll forming apparatus. One method is to incorporate a forming roll with a lip 3 and a forming roll with a rib pattern or uneven pattern 4 (made by etching or engraving the roll surface) into a forming apparatus consisting of a known main roll group. put. If you want to mold both Rip 3 and a rib pattern or uneven pattern, use both rolls, but if you want to mold only Rip 3, rib pattern, or uneven pattern 4, raise the upper roll that is not being used and move it away from the pass line. If removed, the slats will simply slide on the lower roll and will not cause any problems in roll forming. Note that if the roll has unevenness, a difference in circumferential speed will occur and a beautiful surface will not be obtained, so the split mold portions with the rib pattern or the uneven pattern are designed to be able to rotate relative to each other. For this reason, in the case of the main roll, the gears connected to the drive source are removed to make it free, allowing it to rotate using only frictional force.

Another method is to make the main forming roll a split type, and only the split roll for processing the proton part 2 (Fig. 1) of the slat can be replaced with a split roll for lip forming, rib pattern, or uneven pattern forming. If this is done, only one or two specific sets of roles need to be rearranged as needed.

Still another method is to incorporate an auxiliary roll between the main rolls to form a ribbed pattern or an uneven pattern (see FIG. 9). As mentioned above, the auxiliary rolls are designed so that both the upper and lower rolls can be removed from the pass line, so when they are not used, the slat material can be passed through without contacting the auxiliary rolls at all.

Furthermore, of a pair of upper and lower rolls, only one of the upper and lower rolls is etched or engraved to form a rib pattern or an uneven pattern, and the other roll is made of hard urethane or hard rubber. , a material passes between the two, and a rib pattern or an uneven pattern can be formed on the slat surface.

Of course, if a pattern is not to be formed, the upper roll may be raised.

FIGS. 6 and 7 show an example of the above-mentioned forming apparatus, and when a band material of a predetermined width is passed through the formed slats, slats are continuously formed. The shutter curtains are made by cutting them to length and sequentially connecting them with interlocking parts.

In Figures 6 and 7, 5 is dry horn 1 Kuzing,
Reference numeral 6 denotes an outboard housing, between which a main roll of the forming phase is attached. 7 is an artificial guide stand for #'i strip material, 8 is a side roll stand, and 9 is an auxiliary roll stand. Reference numeral 10 is an electric motor that drives the main roll via a transmission 11. Note that each drive housing 5 receives power from a common drive shaft through gears.

Referring to FIG. 8, the main roll 12 is supported by two roll shafts 13a and 13b mounted between the drive housing 5 and the outboard housing 6.

As is clear from FIG. 8, the main roll 12 is the lower roll 12.
a and the upper roll 12b form a pair, each of which is composed of split rolls. The part where the lip pattern or uneven pattern is formed is processed to make the lip pattern or uneven pattern appear.If the pattern is not required, adjust the adjustment screw j8.1.
All you have to do is take it off the line with a 9. Numerals 14 and 15 are screw-down hooks, which enable adjustment between the upper and lower rolls.

Figure 9 16 shows the auxiliary roll, auxiliary roll star/.

Two roll shafts 17a, 17 supported between doors 9, 9
It is rotatably supported by b and is not driven. Therefore, due to the frictional force between the material and the roll, it naturally rotates at the circumferential speed in response to the flow of the material. In the example shown, the lower roll 16a and the upper roll 1
6b uses an integral roll, but it is also possible to use a split roll as in the example of the main roll shown in FIG.

18 is a vertical adjustment screw for the lower roll shaft 17a, and 19 is a vertical adjustment screw for the upper roll shaft 17b. These adjustment screws 18 and 19 allow the upper and lower rolls to be removed from the grate line, and the gap between the upper and lower rolls can be adjusted by 1IlpA.

As described above, according to the present invention, it is possible to form slats that are long and have an excellent design without making any special modifications to known forming equipment, that is, only specific rolls (or divided rolls) are rolls with lip patterns or uneven patterns. It is now possible to do so. Moreover, it can be inserted into any process step, whether it is the main roll or the auxiliary roll in the roll forming apparatus, and therefore it has become possible to process the slats simultaneously at exactly the same processing speed as normal slats. In particular, by making it possible to create slats with a lip pattern or uneven pattern and lips on both sides with simple equipment improvements, it has become possible to provide shutters with excellent strength and beautiful design at low cost. .

As a result of the excellent rigidity, the slat width can be made larger than the conventional slat width, which can improve production efficiency, save materials, and streamline manufacturing work. , the effect is extremely significant in terms of shutter production.

In addition to the design and strength effects due to the fact that the slats having longitudinal lips on both sides can be easily processed, the following effects are also obtained. In other words, when the shutter is rolled up on the upper winding drum, the slats mutually rotate at the interlocking part and come into contact with each other, but the existence of the lip reduces the pressure force between the slats, which can cause scratches or peeling of the paint. etc. can be prevented.

Furthermore, since it is only necessary to manually prepare an unpatterned area of the material, there is an advantage that the material can be used at low cost and easily.
