Description of the invention () (Please read the notes on the back before filling in this page) The present invention relates to a method of manufacturing a steering wheel for an automobile, especially a kind of * which can be made into a log surface covered with internal calendar glue The automobile steering wheel made of wooden materials and skeletons has excellent robustness and aesthetic appearance. It belongs to the technical scope of the manufacturing method of wooden automobile steering wheels and has industrial utilization value. The wooden car steering wheel has the characteristics of fine texture and comfortable grip *, and also has the advantages of not being easy to be damp, strong, and safe to use. It is generally favored by drivers; however, the previously known wooden car steering wheel There are visible deficiencies and inconveniences in the acquisition of wood or actual use, and it is always difficult to match perfection. Μ log car steering wheel as an example, the use of logs to form a steering wheel, you must obtain logs at an expensive price, and then manually cut out the desired shape, which also includes the surface of the steering wheel for the finger to hold the arc, curved surface detail processing Etc., so that the price of the finished product is high, not acceptable to the general public. One of the ways to reduce the manufacturing cost of the log car steering wheel is printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. For the upper and lower corresponding halves, after holding the Υ-shaped frame in the middle, the upper and lower halves are bonded together by the M adhesive to form the steering wheel. Although the steering wheel has the advantage of low price, but the whole «in terms, In the processing of concave and convex details on the steering wheel surface, it is still very inconvenient due to the limitation of the raw material of curved wood, which makes it difficult to achieve the softness, roundness and streamline beauty on the evening view. Use in areas with large temperature changes can also easily cause cracks and deformations. Furthermore, because the steering wheel is bonded to the upper and lower corresponding halves. • The bonding surface is easy to form the surface gap of the steering wheel. • Especially long-2 — This paper size Applicable to China National Standards (CNS) Α4 specifications (2 丨 Ο297297 mm) Printed Α7 Β7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of the invention () After use, the adhesive chemistry Changes, or any quality difference between the central Y-shaped frame and the curved wood, will make the steering wheel weak and loose, reduce its strength, etc., and form a safety concern. In view of this • In order to improve the lack of Fu Tong ’s log steering wheel, the inventor actively started to study * and after many trial productions, he eventually developed this creation • It can be made of cheap materials, with a more solid structure and a more appearance The wooden steering wheel is meticulous and high-quality, and it is safer to use, and has industrial applicability. That is, the main purpose of the present invention is to provide a method for manufacturing a steering wheel for automobiles, which is a glue made by a specific formula. It is made of bakelite raw materials from waste wood chips fiber. Then add the center fee rack in the powdered pendant to make a prototype. Then cover the outer surface of the wood sheet with a crossbar to heat and press. The rugged and aesthetically pleasing steering wheel achieves the above purpose. The second objective of the present invention is to provide a method for manufacturing a steering wheel for an automobile. In the manufacturing process, inexpensive wood chips are used as one of the raw materials, and the adhesive is integrally formed with the internal expensive frame of the steering wheel, so that a rugged steering wheel can be obtained. . Another object of the present invention is to provide a method for manufacturing a steering wheel for an automobile. In the manufacturing process, it is made of K multi-calendar wood flakes and cotton cloth dipped in glue * to form the raw material of the steering wheel surface, so that it can obtain a wood grain appearance and excellent toughness The finished steering wheel. Another object of the present invention is to provide a method for manufacturing a steering wheel for an automobile. During the manufacturing process, the M mold is pressurized to form the steering wheel, so that a paper size can be produced.
