Description

Bearing crimping cover stamping device Technical Field The utility model relates to the technical field of stamping devices, in particular to a bearing hemming cover stamping device. Background Bearing bead caps, commonly used in miniature bearings, have the primary function of protecting the internal components from dust and other contaminants while maintaining the sealing properties of the grease. Such caps typically employ a crimped design to facilitate engagement with the bearing cup to ensure a sealing effect. In the prior art, the edge of the hemming cover is turned inwards, so that the shape of a final finished product becomes complex, the hemming of the hemming cover is formed by secondary stamping, and in the secondary stamping process, the edge of the hemming cover is deformed when turned inwards due to the lack of support of the inner wall of the hemming cover, so that the production of the hemming cover can be influenced. Disclosure of utility model The application provides a bearing edge rolling cover stamping device which is used for providing support when the edge rolling cover is stamped, so that the problem that the production of the edge rolling cover is affected due to deformation when the edge of the edge rolling cover is stamped and folded is solved, the yield of the edge rolling cover is effectively improved, and the production cost of the edge rolling cover is reduced. The technical aim of the utility model is realized by the following technical scheme: a bearing crimping cap stamping device, comprising: the top of the base is fixedly connected with a mounting frame; The lower die is arranged at the top of the base, and a placing groove for placing the edge rolling cover is formed in the top of the lower die; The upper die assembly is arranged above the base and used for stamping the edge of the edge rolling cover, the upper die assembly comprises an upper die plate, a sliding table and a supporting plate, the top of the upper die plate is connected with the mounting frame through a hydraulic press, a round hole is formed in the middle of the upper die plate, the sliding table is connected in the round hole in a sliding mode, a plurality of supporting plates used for supporting the inner wall of the edge rolling cover are arranged on the annular array of the sliding table, an angle adjusting unit is arranged between the upper die plate and the supporting plates, and a groove used for stamping the edge rolling cover is formed in the outer side of the round hole at the bottom of the upper die plate. Further, a plurality of holding tanks for holding the backup pad are offered to the bottom of slip table, and the backup pad rotates to be connected in the holding tank. Further, the angle adjusting unit comprises a toothed plate and a gear, the gear is arranged at the joint of the supporting plate and the sliding table, and the toothed plate meshed with the gear is fixedly connected to the inner wall of the round hole. Further, the outer wall of slip table has seted up the track groove, the inner wall of round hole corresponds the position fixedly connected with slider in track groove. Further, the bottom of the sliding block is fixedly connected with a gas spring, and the bottom of the gas spring is fixedly connected with the bottom wall of the track groove. Further, a top block is arranged above the sliding table, and the top of the top block is fixedly connected with the mounting frame. In summary, the present utility model includes at least one of the following beneficial technical effects: 1. According to the bearing hemming cover stamping device, when the upper die assembly and the lower die are clamped through the arranged upper die assembly, the upper die plate and the sliding table are enabled to slide relatively by utilizing the supporting force received after the sliding table or the supporting plate is abutted against the hemming cover, so that the supporting plate is enabled to overturn by utilizing the angle adjusting unit, the supporting plate is enabled to provide support for the inner wall of the hemming cover, the deformation caused by lack of support when the hemming cover is turned over can be avoided, and the turn-over quality of the hemming cover is effectively ensured; 2. This bearing crimping lid stamping device, through the air spring that sets up, can be when the hydraulic press is brought the mould assembly and is reset, make the slip table and go up the buffering that receives the air spring between the template slow down the reduction, the backup pad just can be because unable the complete turn-down and contradict crimping of crimping lid this moment to provide the support to crimping lid, make crimping lid by backup pad jack-up drawing of patterns, thereby play the effect of crimping lid automatic unloading, improve the production efficiency of crimping lid by a wide margin.
