The present invention relates to an apparatus for manufacturing compressed metal wire laminated bodies such as gas filters used in gas filters and their spring materials.

魔板等が使用されている。(Conventional Technique 4/Ft) For this type of gas generator, a method that uses high-temperature gas generated by burning gunpowder is widely adopted. It is necessary to use a gas filter to remove harmful substances. As a gas filter for this purpose, a stack of a plurality of stainless steel wire meshes, a metal foam, a metal baffle plate, etc. are used.

の多くの問題を残していた。However, all of the conventional gas filters mentioned above have insufficient elasticity, so when they are housed in the casing, gaps are created, making it easy for high-temperature gas to pass through. Even without this, many problems remain, such as the fact that the gas filter itself is non-uniform and tends to cause high-temperature gas to pass through, and that it takes a lot of effort to load the gas into the casing.

いた。Therefore, the inventors of the present invention first preformed a wavy wire obtained by stretching a coiled metal wire into a ring shape, and further pressed it into a compressed metal wire laminate. We developed a method for manufacturing filters, but we encountered problems such as the fact that the wire drawn from the coil is easily twisted and difficult to handle, the process is complex and difficult to automate, and the compression mold is easily damaged. Many problems remained unsolved.

However, the manufacturing process also had the same problems as above.

To efficiently and easily manufacture a laminated compressed body of metal wire, such as a gas filter or a spring material, in which the wire rod is easy to process and is resistant to melting damage, and is also homogeneous so that there is no risk of short-passing of high-temperature gas. It was completed in order to provide manufacturing equipment that can.

〜１．５ ｍｍ程度の耐熱鋼線が好ましい。When manufacturing gas filters, heat-resistant metal wires such as stainless steel are used as the raw material. If the wire diameter of the metal wire is too small, there is a risk of it melting when it comes into contact with high-temperature gas, while if it is too thick, it will be difficult to process and the gas flow path will become large, reducing its function as a gas cooling and filter. Therefore, the wire diameter is 0.1
A heat-resistant steel wire of about 1.5 mm is preferable.

Due to the difference in the modules between the first gear and the second gear 0ω, if both are rotated at the same speed, there will be a slight difference in the feed speed, which may cause wire breakage. Therefore, if a rotational speed adjustment mechanism such as a conical belt type or variable bitch pulley 2 is interposed between both gears, disconnection can be reliably prevented.

な金属線材積層圧縮体を製造するに適したものである。(Effects of the Invention) As explained above, the metal wire laminated compressed body manufacturing apparatus of the present invention feeds the metal wire supplied from the feeder to a pair of first gears and a pair of second gears of a different module. Since the bending mechanism consists of three-dimensional wave-like bending,
The metal wire laminated compressed body obtained by compressing or shaping the metal wire has a homogeneous structure in which the metal wires are tightly entangled with each other, and short paths of gas are difficult to form inside the body. Moreover, since this metal wire laminated compressed body has appropriate elasticity, it can be easily loaded into the casing, and no gap will be created between it and the casing. Furthermore, since the metal wire laminated compressed body manufacturing apparatus of the present invention is equipped with a tension adjustment mechanism for bent metal wires and a winding mechanism for metal wires equipped with an even winding guide, can be wound with uniform tension and uniform density, making it suitable for producing homogeneous compressed metal wire laminates.
