The method of sand manufacturing (four) sets 10 is to prepare an upper punching die and a punching die for the upper and lower relative sleeves, and between the punching tool and the lower die, and using the punching machine to make the rainbow punch The undercut mask sleeve is combined with an oil-filled envelope to form a black. x This oil-sealed semi-finished product has the appearance of _, but it is the standard of the roundness of the oil-sealed semi-finished product and the rough surface of the surface of the oil-sealed envelope, so it must be supplemented by the latter two private I ' _ plus 1 oil-sealed semi-finished product, so that its degree of roughness: the surface roughness meets the standard required by the oil seal. As mentioned above, both turning and glazing are time-consuming and cost-effective; The cost of red is quite high. [New content] The specification of the envelope requires that the interest of the master and the t-piece is to expose the stamping die, and the oil seal of the vertical is not _ continuous processing, it can reach the oil 5 M330872 It can be seen that, in order to achieve the above object, the present invention provides a stamping die which is stamped and molded into a sheet-and-oil stamping sleeve, the punching mask comprising an upper display-lower mold, and the upper mold and the lower mold sleeve After the combination, there is a forming gap, and the predetermined thickness of the sheet is made larger than the forming gap, so that the punching mask can form and calender the sheet to form the oil jacket. According to this, the forming of the stamping die of the present invention The gap is smaller than the predetermined thickness of the sheet material, so the stamping die of the present invention is formed while being subjected to the effect of stretching, and the dimensional precision after forming is high, the thick chain is small, and the roundness and the manufactured roundness are The surface roughness has been able to reach the specifications of the oil jacket. [Embodiment] In order to enable your members to have a more in-depth understanding of the characteristics, purpose and efficacy of this creation, _lifting - health _ and with the schema description After: Referring to "苐2图" and "3rd drawing", the original stencil 20 includes an upper mold 21 and a lower mold 22, and the upper mold 21 and the lower mold 22 have a Forming gap D. And the sheet material 3 used has a predetermined thickness Ε 'and the pre-turn thickness Ε is larger than the forming gap )), if the predetermined thickness ε is 1.23⁄4 m (mm) 'the forming gap 】 can be 〇 · 65~〇·9 times, that is, the forming gap D is between 0·78 mm (mm) and 1 mm (mm), and the plate 30 may be SAE1008 steel. In addition, the outer periphery of the upper mold 21 can extend a surrounding portion 23, which can increase the thickness of the upper mold 21, so that the deformation amount of the upper mold 21 can be reduced during forming, and the formed oil can be further increased. The roundness of the envelope 1〇. 6 M330872 A side portion of the lower mold 22 can be looped with a cutting portion 24, and a die ring 25 can be looped between the cutting portion 24 and the lower mold 22. Please refer to "Fig. 4-1", "Fig. 4-2" and "Fig. 4-3" together. 'This creation is used to form the sheet 3 into an oil seal 1〇, which is used. a punching machine 40, the punching machine 40 includes an upper moving member 41 and a lower fixing member 42. The upper moving member 41 and the lower fixing member 42 respectively set the upper mold 21 and the lower mold 22, and the punching machine 40 After the sheet 30 is placed between the upper mold 21 and the lower mold 22, the upper moving member 41 is moved toward the lower fixing member 42, so that the upper mold 21 and the lower mold 22 are shaped to calender the sheet 30, and The oil seal 10' is manufactured in which the cut portion 24 and the upper mold 21 can cut off excess portions of the outer periphery of the sheet material 3, so that the sheet material 30 can be continuously fed using the elongated sheet. After the mold-removing ring 25 is formed, the oil seal sleeve 10 which can be pushed up against the forming is released from the lower mold 22 to prevent the oil seal sleeve 1 from being caught on the lower mold 22. As described above, since the forming gap of the stamping die 2) is smaller than the predetermined thickness E, it has the effect of calendering at the same time of forming, so that the size of the oil seal 10 after forming is more precise and the oil seal can be increased. The roundness of the roundness and the reduction of the surface roughness. That is, the present invention can reduce the roundness and surface of the oil-sealed sleeve 1 after forming by reducing the forming gap between the stamping dies 20 while forming and calendering while increasing the rigidity of the upper mold 21. Roughness meets the required specifications, so the cutting power and polishing are not saved, and it can be manufactured quickly and at a cost. In summary, the description is only for the preferred embodiment of the present invention, and is not intended to limit the implementation of the creation, that is, the variation and modification of the content of the special fiber package according to this book should be the creation of the creation. _ Fan Wei.
