New description: [New technical field] This creation department is about "a bicycle front fork structure improvement", especially a front fork shoulder cover, a front vertical pipe, and a hydraulic inner pipe. In addition to the bicycle, the cockroach effectively increases its overall strength and reduces its process. [Prior Art] According to the presently known bicycle front fork, as shown in the ninth figure, it includes: a front fork shoulder cover (90), a front fork standpipe (91) and a two-oil inner tube ( 92), wherein the front fork shoulder cover (90), the front vertical pipe (91) and the hydraulic inner pipe (92) are separately formed, and the center and the lower sides of the fork shoulder cover (90) are divided There is a locking hole (901) (902) which can be inserted into the front and the inner tube (91) and the hydraulic inner tube (92), so as to be screwed after the penetration, ·*,···% The fork shoulder cover (90), the front fork vertical pipe (91) and the oil pressure inner pipe (92) can be combined, and the two oil pressure inner pipe (92) is also provided with a hydraulic outer pipe, thereby forming A bicycle before again. However, because the front fork shoulder cover (90), the front fork standpipe (91) and the hydraulic inner pipe (92) need to be formed separately, and then combined, the production will be cumbersome and time-consuming, and not economical. Benefits, and the need to combine the bicycles before, the overall structural strength will be poor' so that when the bicycle often travels through the rugged road, the fork will be easy to damage and shorten its service life. Therefore, if we can develop a bicycle fork that is integrally formed, 俾 effectively reduce the M373319 less process and combination steps, the overall structural strength of the bicycle front fork is better, when the bicycle often travels through the rugged road, Lin Chun It is the problem that the creator wants to improve. Therefore, the creator has this idea, which is the idea of thinking and creation. He has designed it with many years of experience. After many discussions and trials, the shirts are repaired and the works are promoted. [New content] Technical features to solve the problem: This creation provides a kind of bicycle front structure improvement. The front fork of the bicycle is attached to the front and the shoulder cover. The body is formed with the front and the second oil pressure inner tube. In the past, the pipe was connected to the handlebar of the car, and it was able to rotate before the bicycle was operated by the bicycle handle during riding, and the oil (4) pipe outer sleeve was provided with a hydraulic outer pipe to utilize the filling in the oil pressure. The hydraulic oil between the inner and outer officials can cooperate with the hydraulic outer tube and the oil waste inner tube to force each other to translate, and can achieve the purpose of shock absorption during riding, and the bicycle is also in front of the bicycle. After the billet heating, the secondary forging, the semi-finished product reheating, and the second forging extrusion, it can be made into a shape, thereby obtaining a kind of bicycle structure improvement. Compared with the efficacy of the prior art: (1) The creation provides a bicycle structure and improvement. The bicycle front fork is integrally formed with a front fork shoulder cover, a front sill and a second saki, so the phase requires the remaining process of the M373319. , the production can be completed, so that the bicycle front fork is more in line with the production and processing efficiency, _ the same as the competition will be more advantageous. a) The creation provides a bicycle structure and improvement. The front fork shoulder cover and the front fork and the oil-saw-saw-saw body are formed. Therefore, the overall structural strength is strong. When the bicycle often passes through the rough road, the self The fork is not easy to damage. [Embodiment] The level stomach review committee can have a better understanding and understanding of the purpose, characteristics and efficacy of this creation. Please refer to the example of the [Tai Lai single system] for details. The details are as follows: ^ / Money, First, as shown in the first and second figures, the bicycle front fork (10) is attached to the rigid shoulder cover (11) - the front and the vertical tube (10) and the two oil pressure inner tube (10)' In the past, the standpipe (10) is connected to the bicycle handle (10), and the bicycle front fork (10) can be operated by the bicycle handle (10) during riding, and the oil-colored inner tube: (13) the outer set is provided with a female outer tube. (10), the hydraulic oil 'filled with the oil pressure outer tube (10)) and the oil auxiliary tube (10) filled with the inner and outer tubes '03) (10) can be forced to translate with each other, and can achieve buffer reduction during riding. For the purpose of the earthquake, the bicycle frog (10) is sequentially formed by billet heating, one-time forging, semi-finished product reheating, and secondary forging extrusion. Where the billet is heated, the metal billet (40) is heated to a moderately high temperature (generally above the recrystallization temperature, but not enough to allow the billet to melt), making it easier to process M373319 deformation. In the cavity (51) of the heated saki (4G) release molding die (10), the embossing (10) of the same shape (51) is carried out on the blank (10). Test 'and Lai (5)) in the position of the front fork vertical tube (10) and the second oil (four) tube (10), the base outside the county has a room for the sister's capacity (52), please also view it as shown in the third figure; One forging, using the first and second molds of the first forming die (50), and forging the blank (40) into the same position as the cavity (51), and because the cavity (51) is still There is no space for the material (10)', so when forging, its (10) can synchronously fill the space (52) to form a semi-finished product* with an extension (61). It is shown in the fourth figure. The semi-finished product is reheated, which is the step of reheating the removed semi-finished product (60). After heating to the silent temperature, 'put the semi-finished ^(10)) a cavity (71) of the second molding die (70), and the cavity (71) is integrally formed at a position relative to the front vertical pipe (12) and the two oil pressure inner pipe (13) The forming passage (72), which is formed by the forming passage (72), can provide a punch (8 inch) having an outer diameter smaller than the inner diameter thereof, and the gap between the forming passage (72) and the thin (10) outer closing. It is the thickness of the pipe formed by the front vertical pipe (10) and the oil pressure inner pipe (13). Please refer to it as shown in the fifth figure. The second forging extrusion is performed by using the second forming die (7〇). The merging of the lower mold, the punch (80) is inserted into the forming passage (10) from the outside to the inside, and the extension (61) of the semi-finished product (10) can be processed. 俾 The additional material of the extending portion (10) is formed into 6 The M373319 shaped channel (72) and the punch (10) are formed by extrusion, and then the body is formed with a river fork shoulder cover (11), a front g pipe (10) and a hydraulic inner pipe (10) before the bicycle (10), and Because the diameter of the front pipe (10) and the oil pressure (10) or the thickness of the pipe wall can be changed by the outer diameter of the forming channel (10) and the punch (10), so the bicycle will be allowed to be in front of the processing. (10) More variable tilting, please _ as seen in the sixth, seventh and eighth figures, and when the second forming mold (7〇) is opened, the bicycle can be taken out before (10) . By the structure of the above specific embodiment, the following benefits can be obtained: (1) The bicycle rigid fork (10) is formed with a front shoulder cover (8), a front vertical pipe (10) and a second oil β. inner S (13) Therefore, it is relatively unnecessary; the screw-locking process can be made into a production process, so that the self-driving vehicle (10) is more in line with the economic benefits of production and processing, and the competition between the industry will be more advantageous, (2) The front shoulder cover (1)), the front cymbal (10) and the oil house s (13) are formed in a body-like manner, so the overall structural strength is excellent. When the bicycle is often used on the road surface, the bicycle front fork In summary, the creation of the material has reached a breakthrough, transfer design, and the improved content of the creation 'at the same time can achieve the marriage and progress of the industry and rely on any publications' also Brewed, # compliant with the provisions of the Patent Law, and 爰 ( (10) type patent application, to the fishing bureau review board to grant legal patents 'to the pray.
