410202 五、發明說明（1) 本發明主要是一種自行車車架管件之製造方法，此一 製造方法所製造之非圓形自行車車架管件，可以讓自行車 車架的外觀設計有更多種形狀的變化，而且能減少自行車 車架管件的焊接程序，提高車架整體之強度。 按，現今多元變幻的市場需求，已使得自行車車架之 外觀不再滿足於現有之形狀，比如傳統之鑽石形車架；以 及傳統運用圓管焊接之車架；加上車架已逐漸由剛性車架 走向避震車架之設計路線，車架形狀已有很大的變化；車 架所使用的金屬材質也由一般鋼鐵、鉻鉬鋼走向鋁合金及 鎂合金、鈦合金等高級合成金屬製造車架管件，再加以焊 接成型自行車車架，所以車架管件已不再都是圓形斷面的 形狀，管件斷面形狀有方形、長方形' 圓形等許多不同 的形狀；另有以鋁板沖壓成型再加以焊接之自行車車架製 法，如公告第3 1 1 1 2 4號發明專利，其所製成之自行車車架 上管及下管為一體，屬一體成型形態。 多樣變化之車架設計，相對的對車架之強度也有提高 之需求，因為材質及形狀的改變，以及避震的設計，加上 速度有逐漸加快與越野性能需求，除了利用材料本身的物 性加強外，車架之組成構件如本發明所製作之管件等，利 用材料力學、應用力學加上結構之配合，適當的加強結構 而又不會增加太多重量，甚至減輕重量，是現今車架結構 設計的課題之一，本發明即是因應此一趨勢所研發之自行 車車架管件製法。 本發明是運用金屬板材，以機械加工方法如沖壓或輥410202 V. Description of the invention (1) The present invention is mainly a method for manufacturing bicycle frame pipe fittings. The non-circular bicycle frame pipe fittings manufactured by this manufacturing method can make the appearance design of bicycle frames have more shapes. Changes, and can reduce the welding process of bicycle frame pipe fittings, improve the overall strength of the frame. According to today's diversified and changing market demands, the appearance of bicycle frames is no longer satisfied with existing shapes, such as traditional diamond-shaped frames; and traditional frames welded with round tubes; plus the frame has gradually changed from rigid The design direction of the frame towards the suspension frame has changed greatly. The metal material used in the frame is also made of general steel, chromium-molybdenum steel, aluminum alloy, magnesium alloy, titanium alloy and other advanced synthetic metals. Frame pipe fittings are welded together to form a bicycle frame, so frame pipe fittings are no longer round in cross-section. The cross-sections of pipe fittings are square, rectangular, round, and many other shapes; there is also aluminum stamping. The bicycle frame manufacturing method of forming and then welding, such as the invention patent No. 3 1 1 12 is published, the upper tube and the lower tube of the bicycle frame made of it are integrated, which is an integral molding. The variety of frame designs has a corresponding need to increase the strength of the frame, because of changes in materials and shapes, as well as the design of suspension, coupled with the need for speeding up and off-road performance, in addition to using the physical properties of the material to strengthen In addition, the components of the frame, such as the pipe fittings made by the present invention, use material mechanics, applied mechanics, and structural cooperation to appropriately strengthen the structure without adding too much weight or even reducing weight. This is the current frame structure. As one of the design issues, the present invention is a bicycle frame pipe manufacturing method developed in response to this trend. The present invention is the use of sheet metal by mechanical processing methods such as stamping or rollers

Description of the invention (2) The pipe fittings are pressed into a closed section, and then the joint is welded to a completely closed hollow pipe fitting by welding. The shape of the pipe fittings can be square, rectangular, oval, etc. Various joints of the frame, such as the head tube, five-way tube, and seat tube, are welded into a bicycle frame. This can overcome the monotonous shape of traditional tube fittings. In addition to various sections, the overall shape of the tube can also be designed to match the design. The big tail is small, or the middle section is reduced, and the space for change after the combined welding of the frame is relatively enlarged; the structure with only one bead has relatively higher strength, and the appearance also looks more beautiful and simple. The design of the bicycle frame has a lot of room for play. In order to allow your reviewers to further understand the present invention, the following is a simpler and more common bicycle frame pipe fittings and examples, with illustrations and drawing numbers, a detailed description of the composition of the present invention and its achieved effects, such as After: Description of the drawings: The first figure is a schematic perspective view of the preliminary closing of the pipe fittings of the present invention. The second figure is a three-dimensional schematic view of the welding of the pipe fittings of the present invention.
