Description of invention: [Technical field to which the invention belongs], this method of bribery metal reinforcement, especially related to - face only borrowing, stamping into W can be offered (four) set of Wei [previous technology] electricity please refer to "1st As shown in the figure, the oil jacket 1 is an important part of the hydraulic machine, which is used to keep the lubricating oil from being exposed, so that the roundness of the oil jacket 10 must meet the specifications. The method for manufacturing the oil jacket 10 is to prepare the upper and lower molds for the upper and lower relative sleeves, and to set the sheet to the upper mold and the lower mold. Forming an oil seal semi-finished product. The semi-finished product of the oil seal has a prototype shape, but it is formed by a conventional stamping method, so that the roundness and surface texture of the semi-finished product of the oil seal fail to reach the standard required for the oil seal, and thus the conventional processing method $, which must be further processed by subsequent turning and polishing, and / / The envelope is half-formed into ασ 'to make its roundness and surface roughness satisfy the standard required by the oil jacket to produce the oil envelope. The processing method as described above is cumbersome in operation, and the turning and polishing processes are time-consuming and quite complicated, and it is difficult to mass-produce at a high speed and is quite expensive. SUMMARY OF THE INVENTION The main object of the present invention is to disclose a processing method for the Chongxian shape, which can meet the specifications of the oil seal without subsequent processing. From the above, in order to achieve the above object, the present invention provides a method for processing 5 1313198 for forming an oil seal, the steps of which comprise preparing a mold, preparing a sheet, preparing a punch, wherein the prepared sheet has a The pre-twist thickness 'saki mold includes - upper mold and lower mold, and the upper mold and the lower mold sleeve are combined with - 彡 _, and the job thickness is formed by the gap; the punch machine includes - the upper moving part With the fixed mechanism, the upper moving member and the fixed money member are placed on the upper mold, and the sheet is placed between the upper mold and the lower mold, and then the upper moving member is allowed to be moved. Moving the lower fixed member to the lower mold to fit the lower mold, forming and rolling the sheet to form the oil seal. - According to this, the molding gap of the mold used in the present invention is smaller than the pre-twist thickness of the sheet. Therefore, the present invention has the effect of being formed while being stretched, so that the dimensional precision after molding is high, and the coarse sugar content is small. The roundness and surface roughness of the seals that have been produced can reach the specifications of the oil seals. [Embodiment] In order to enable your members to have a deeper understanding and recognition of the features, purposes and effects of the present invention, The preferred embodiment is described with reference to the following figures: Please refer to the "Fig. 2", the processing method of the present invention is used to form the oil-sealing sleeve 10 (as shown in "Fig. 1"), first preparing a The mold 2 includes a top mold 21 and a lower mold 22, and the upper portion has a forming gap D after being aligned with the lower mold 22. Please refer to the "Fig. 3" and then prepare a sheet of 3 〇, the sheet 3 〇 has a predetermined thickness E, and the predetermined thickness E is greater than the forming gap 1 if the predetermined thickness E is 1.2 mm (deleted ''The forming gap D can be between 6 1313198 〇. 65~0·9 times, that is, the forming gap D is between 0.78 mm (mm) and 1.08 mm (mm), and the sheet 3 〇 can be SAE1〇〇8 steel. Referring to "Fig. 4-1" and "Fig. 4-2", a punching machine 40 is further prepared. The punching machine 4 includes an upper moving member 41 and a lower fixed member 42, and the upper moving The upper part 21 and the lower mold 22 are separately disposed between the upper part and the lower fixed part, and the sheet 3 is placed between the upper mold 21 and the lower mold 22, and the upper moving part _ The fixing member 42 moves to make the upper mold

If the speed of the motor is controlled to decrease, the moving speed of the upper moving machine 41 toward the lower fixed member 42 is increased. v slows down, the forming speed is changed to 2 to reduce the strain rate of the material forming, which can further increase the roundness of the oil thread 10 after forming and reduce the surface thick chain, as the speed of the motor is The running catch. 9_ is reduced to _~7 turns, the surface roughness of the pot can reach 0.2 micron (egg) to 0.9 micron ((4). See "Figure 4-3" for the other 'outside the upper mold 21 The surrounding can be extended:: the part 23' is increased by the surrounding object. When forming, the deformation amount of the upper section can be reduced, and the rear oil jacket is __ degrees. Before the ordering, the cutting section 24 and the cutting portion 24 are The upper mold 21 can cut off the excess portion of the outer periphery of the plate member 30, so that the plate member 30 can be continuously fed using the elongated sheet. Further, a die can be arranged between the cutting portion 24 and the lower die 22. The ring 25, after the forming ring 25 is formed, can be lifted and pushed against the formed oil seal 10 from the lower die 22 to prevent the oil seal 10 from being caught in the lower die. 22. As described above, the present invention reduces the moving speed of the upper mold 21 while reducing the moving speed of the upper mold 21 by reducing the forming gap between the molds 2, thereby slowing down the forming speed. Moreover, the rigidity of the upper mold 21 is increased, and the roundness and surface roughness of the oil seal 10 after forming can be made to meet the required specifications, so that subsequent turning and polishing processes are not required, and the mass can be quickly mass-produced. The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent variation and modification of the content of the patent application scope of the present invention. It should be the technical model of the present invention. [Simplified illustration of the drawings] • Fig. 1 is an external view of the oil seal.
