この発明は、薄金属板により筒体を形成するに
際し、筒体内側へ環状鍔を設けることを目的とし
た補強金属筒の製造法に関するものである。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a method for manufacturing a reinforcing metal cylinder for the purpose of providing an annular flange on the inside of the cylinder when the cylinder is formed from a thin metal plate. It is.
（従来の技術及びその解決課題）
従来、金属筒の補強としては環状凸条又は凹条

ような筒体の製造法を提案するものである。(Prior art and problems to be solved) Conventionally, it has been known to provide annular protrusions or grooves to reinforce metal cylinders. Even if a strip (e.g. 2mm to 3mm deep) is provided, the weight will be 5Kg/cm 2 to 10Kg/cm 2
It may not be sufficient as a shape-retaining cylinder for filters, etc., which are subjected to pressure of In such a case, the problem can be solved by increasing the thickness of the material metal plate (for example, using a thin metal plate with a thickness of 1 mm), but the thickness
Since the amount of material used is twice as much for a thin metal plate of 0.5 mm or less and a thin metal plate of 1 mm thickness, it is of course desirable to use a thin metal plate and maintain the specified strength. . Therefore, by providing an annular flange (approximately 5 mm in width) on the inner surface of the cylinder, a pressure resistance of over 10 kg/cm 2 was obtained with a cylinder made of a thin metal plate with a thickness of 0.5 mm. Therefore, we propose a method for manufacturing such a cylinder.
（課題を解決する為の手段）
この発明は矩形の薄鉄板を円筒状に成形すると
共に、薄金属板の端縁のはぜ代を所定間隔で切除

来の問題点を解決したのである。(Means for Solving the Problems) The present invention involves forming a rectangular thin metal plate into a cylindrical shape, and cutting off the edges of the thin metal plate at predetermined intervals to form annular flanges at the portions. Thus, the above-mentioned conventional problems were solved.

に形成した補強金属筒の製造法である。 That is, the present invention connects both ends of a thin metal plate with edges cut out at predetermined intervals to form a cylinder, and in the side wall of the cylinder, an annular recess is formed for each edge cut out part. This is a method for manufacturing a reinforced metal cylinder, in which the cylinder is pressurized in the axial direction from both end surfaces to form the annular recess into a double-walled annular collar.

板製筒体に応用し得ることは勿論である。(Embodiment) That is, to explain the present invention with reference to the embodiment shown in FIGS.
Edges 2, 2a are provided on both left and right edges of the blade, and cutouts 3, 3a are provided at predetermined positions of each edge 2, 2a.
A cylindrical body 4 is formed by fitting the thin iron plates 1 together in a usual manner, and annular recesses 5, 5 are provided in the side wall of the cylindrical body 4 so as to pass through the positions of the cut-out parts 3, 3a. (Figure 2). Next, the pressure plates 6, 6 are brought into contact with the upper and lower end surfaces of the cylinder 4, and the pressure plates 6, 6 are moved as shown by the arrows 7, 7.
By applying pressure in the direction of
(Figure 3). 10 in the figure is
This is the gap. The cylindrical body manufactured according to the present invention is, for example, a perforated cylinder having a large number of small holes 9 in the side wall (for example, a shape-retaining cylinder of an oil filter) as shown in FIG. 4, or a bottom plate is provided at the lower end of the cylindrical body 4. Can be used as a metal can. 11 in FIG. 5 is a paper filter. Although the above embodiments have been described with respect to thin iron plates, it is of course applicable to thin aluminum plates and other thin metal plate cylinders.
この発明により成形する環状鍔の数に制限はな
く、原則的には多い程強度が増大するが、余り多
く設けると製品筒長に比し、矩形板を二重壁分だ
け長くしなければならないので、材料節減という
本来の効果が低減するおそれがある。そこで筒体
の直径と同等の間隔で環状鍔を設けることも一基
準となろう。要は材料とする薄金属板の厚味と求
める強度により要求を満すべく環状鍔数を決める
ことになる。 There is no limit to the number of annular flanges formed by this invention; in principle, the greater the number, the greater the strength; however, if too many are provided, the length of the rectangular plate must be increased by the length of the double wall compared to the length of the product cylinder. Therefore, the original effect of material saving may be reduced. Therefore, one standard would be to provide annular flanges at intervals equal to the diameter of the cylinder. The key is to determine the number of annular collars to meet the requirements based on the thickness of the thin metal plate used and the required strength.

産できる効果がある。(Effects of the Invention) That is, according to the present invention, after providing an annular recess in the edge cut portion of a cylindrical body wall formed by providing a cut portion in the edge edge, pressure is applied in the axial direction from both ends of the cylindrical body. So,
This has the effect of instantaneously manufacturing annular flanged cylinders of the same shape. However, if the depth of the annular recess is regulated, the width of the annular flange is automatically determined, which has the effect of allowing mass production of homogeneous products.
