Description

Sealing ring spinning forming equipment Technical Field The invention belongs to the technical field of seal ring machining, and particularly relates to seal ring spinning forming equipment. Background The C-shaped metal sealing ring is a common elastic metal sealing ring, the cross section of the C-shaped metal sealing ring is C-shaped, and the sealing surface of the C-shaped metal sealing ring is attached to the sealing surface of the corresponding piece by utilizing the compression rebound resilience of the C-shaped metal sealing ring, so that the C-shaped metal sealing ring is used for axially sealing the end surface perpendicular to the rotation axis and is used for preventing fluid leakage. The core principle of the seal ring spinning forming processing technology is that a main shaft drives a blank to rotate, a spinning roller moves according to a preset track and applies pressure, so that the material is subjected to continuous plastic deformation point by point, and finally, the seal ring meeting the design requirement is formed. The utility model discloses a metal sealing ring shaping frock in the chinese patent of the publication number CN112642912B of authorizing, including spinning anchor clamps and rolling cutter, spinning anchor clamps are used for the clamping to wait to process semi-manufactured goods annular slab, and rolling cutter is used for exerting the required pressure of spinning processing to the semi-manufactured goods annular slab after the clamping, and wherein, spinning anchor clamps include clamping shaft subassembly, child mould subassembly and clamp assembly, child mould subassembly detachable sets up in clamping shaft subassembly. The existing seal ring spinning forming device is generally provided with supporting pieces on the left side and the right side of the seal ring and used for supporting the metal ring, so that the metal ring is prevented from shaking left and right in the spinning process to cause spinning deflection. However, the existing supporting member can only limit the left and right shaking of the metal ring, and can not limit the shaking of the metal ring in the front-rear direction, so that the metal ring is deviated in the front-rear direction in the spinning process, and waste products are generated. Disclosure of Invention The invention aims to provide a seal ring spinning forming device, which aims to solve the problem that a support piece in the prior art can only limit left and right shaking of a metal ring and can not limit the shaking of the metal ring in the front-back direction, so that waste products caused by front-back offset of the metal ring in the spinning process are avoided. In order to achieve the purpose, the sealing ring spinning forming device comprises a lower die assembly, an upper die assembly and auxiliary forming assemblies arranged on the left side and the right side of the lower die assembly, wherein the auxiliary forming assemblies comprise adjusting support rods and auxiliary support pieces, the upper die assembly comprises an upper die holder, transmission grooves extending in the vertical direction are formed in the left side and the right side of the front wall of the upper die holder, the lower side of each transmission groove penetrates through the upper die holder, and transmission racks extending in the vertical direction are fixedly arranged on the sides, close to each other, of the two transmission grooves. The auxiliary support piece comprises an auxiliary support shaft which is rotatably arranged at one end of the adjusting support rod, the axis of the auxiliary support shaft extends along the front-back direction, the rear end of the auxiliary support shaft penetrates through the adjusting support rod and then is sleeved with a transmission gear, the transmission gear is located in a transmission groove and meshed with a transmission rack, a torsion spring is arranged between the inner wall of the transmission gear and the outer wall of the adjusting support rod, two auxiliary clamping wheels are sleeved on the outer wall of the auxiliary support shaft through threads, and when the adjusting support rod rotates forwards or backwards, the two auxiliary clamping wheels can be mutually close to or far away from each other. The device has the advantages that through the meshing and matching of the transmission gear and the transmission rack, when the upper die holder descends, under the meshing action of the transmission gear and the transmission rack, the auxiliary supporting shafts positioned at the left side and the right side of the lower die assembly reversely rotate to enable the two auxiliary clamping wheels to be close to each other, so that the metal blank is clamped in the front-back direction, the displacement and vibration of the metal blank in the front-back direction are effectively restrained, the auxiliary supporting shafts positioned at the left side and the right side of the lower die assembly are
