Description of the invention (1) " '" — [Field of invention] v) The present invention relates to a method for manufacturing a footrest tube seat at the bottom of a seat. In other words, it particularly refers to a manufacturing method of an integrally-formed aluminum extrusion-type support socket that can reduce manufacturing costs and increase strength. [Description of know-how] Generally, furniture that can be used for standing, such as table legs, chair legs, low stools, computer chairs, etc. In order to achieve a stable standing effect, the supporting leg at the bottom usually adopts a multi-manifold style. The design of the feet, as shown in the first figure, the manufacturing methods used in the past to support these sockets 1 are as follows: Step 1. Please refer to the second figure to prepare a hollow embryo tube 101 with a predetermined length and a hollow shape, A pipe with a diameter different from that of the embryo tube 101 is selected for cutting to prepare several feet 102. Step 2: Each leg 102 is subjected to bending forging and lead angle processing using a forming die, and the legs 102 are bent into a predetermined shape. Step three: Next, the legs 102 are welded to the embryo tube in sequence. Step 4: At last, the welding part of the embryo tube 1 〇1 and each leg 1 〇2 is subjected to multiple grinding and polishing operations to eliminate welding marks, and a bright and flat tube seat 1 can be obtained. . From the foregoing, it can be known that the conventional manufacturing method, because the embryo tube 101 and the foot 102 are connected by welding instead of integral molding, except for the risk of insufficient strength, and the processing process is obviously very complicated, reducing production. The efficiency and economic benefits are not consistent. Furthermore, the welding position of the feet 102 and the embryo tube 101 must be quite accurate; otherwise, the socket 1 will be unstable.

The above is the manufacturing method of the integrally molded aluminum extruded support socket of the present invention (please read the back Note that this page will be refilled.) An overview of the associated structure of each component. Then, the effect expected of the present invention can be stated as follows: 1. From the above, it can be seen that the present invention uses extruded aluminum pipe 1 〇, by adding a connecting plate 丨 丨, and then axially cut along its groove l3, the number of pipe sections 100 of the base 100 can be increased, and pipes with different numbers of feet can be made according to different needs. It is extremely convenient. Second, and more importantly, the manufacturing method of the present invention can be integrally formed without using the necessary processing procedures such as pipe cutting, welding, and grinding. A manifold manifold 100 has better structural strength than the conventionally welded socket 1, and because it does not require welding, it does not produce welding marks. The frame is more beautiful, which can simplify the process to In addition, in the above-mentioned manufacturing method of the present invention, the connecting plate 11 at the top of the pipe 10 can be sharply made close to these branch pipe sections 14 to make the top section of the pipe hollow, so as to reduce the whole. The weight 'or' can be used to forge the branch tube 14 into a round tube to facilitate the installation of rollers. 1 [It is mentioned that 'in this book, use the ... to maintain a straight shape, plus avoidance.
