Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0036] see Figure 2 to Figure 4 , the present invention provides a large-scale gasket metal skeleton without welding technology manufacturing process, including the following steps:
[0037] 1) Material, according to the thickness of the metal sheet, we adopt different heights of material acquisition. The metal sheet with a thickness of 0-10mm uses a laser cutting machine to take the elliptical ring; the metal sheet with a thickness of 11-25mm uses a flame cutting equipment to take the elliptical ring; For metal plates with a thickness of more than 26mm, use water jet cutting equipment to take elliptical rings.
[0038] 2) Cold simmering and deformation, cold working the elliptical ring to a ring with a specified outer diameter to obtain a ring body;
[0039] 3) High temperature forming, using hot extrusion forming device to heat t...
