Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a bearing curling cover punching device. Background Art

[0002] The bearing seal ring curling cover stamping device is a device dedicated to the manufacture of bearing seal rings. Its structure includes the main punch, die, drive system and control system. The punch is responsible for applying force, the die supports and positions the seal ring, and the drive system provides power through a hydraulic or pneumatic system. The control system monitors and adjusts the stamping process. The working principle is based on mechanics and materials science. The punch stamps the seal ring to cause it to undergo plastic deformation. During this process, the material will flow and gradually change its shape, eventually forming a curling structure. This processing process improves the sealing performance, wear resistance and dustproof effect of the bearing, ensuring the excellent performance of the bearing seal ring in motion and environment. However, after the current curling cover stamping device completes the stamping action, the workpiece formed by the stamping and curling is retained in the lower mold. The staff still needs to actively pick up the workpiece in the mold when the mold is separated. Due to manual intervention, the running speed of the production line is limited, and in large-scale production, this becomes a bottleneck restricting the overall production capacity. Workers need to spend time separating the mold and picking up the workpiece, which reduces the continuity of the production line. In the frequent mold separation and picking process, workers are prone to risks such as misoperation, injury or fatigue, which not only affects the work experience of employees, but also increases the difficulty of safety management in the workplace.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: a bearing curling cover punching device, comprising a circular frame 1 and a lower mold 4 installed at the bottom of the circular frame 1, a hydraulic lifting unit 2 is installed at the top of the circular frame 1, and an upper mold base 3 for punching a sealing cover to form a curling is installed at the movable end of the hydraulic lifting unit 2, a C-shaped bottom plate 5 is installed at the bottom of the circular frame 1 outside the lower mold 4, an electric double-axis moving unit is installed at the top of the C-shaped bottom plate 5, a Z-axis movable end of the electric double-axis moving unit is installed with a embossed plate 11, and an electric clamp 12 is installed on one side of the surface of the embossed plate 11, and the electric double-axis moving unit drives the positions of the embossed plate 11, the electric clamp 12 and other components on the Y and Z axes;

[0019] The hydraulic lifting unit 2 includes a hydraulic cylinder 201 installed at the top of the circular frame 1, and a support plate 202 installed at the bottom end of the piston rod of the hydraulic cylinder 201, and the bottom end of the support plate 202 is fixedly connected to the top end of the upper die base 3;

[0020] Guide rods 203 are fixed on both sides of the top of the support plate 202. The top of the guide rods 203 penetrates the outside of the circular frame 1. In the process of the upper die seat 3 being lifted up and down, the guide rods 203, the support plate 202 and the upper die seat 3 are pushed or pulled by the hydraulic cylinder 201. In this process, the lifting stability of the upper die seat 3 is improved by the guide rods 203.

[0021] Both sides of the bottom of the upper die seat 3 are fixed with columnar protrusions, and both sides of the top of the lower die 4 are provided with lower grooves which are concentric with the columnar protrusions. The external feeding device actively puts the sealing cover to be stamped and curled into the lower groove at the top of the lower die 4, and the staff starts the hydraulic lifting unit 2 to work, and the hydraulic lifting unit 2 drives the upper die seat 3 downward until the upper die seat 3 and the lower die 4 are closed to complete the curling work of the sealing cover;

[0022] The electric dual-axis moving unit includes a crossbeam 7 slidably mounted on one side of the top of the C-shaped bottom plate 5, and a Y-axis screw electric linear module 6 mounted on the other side of the top of the C-shaped bottom plate 5, the movable end of the Y-axis screw electric linear module 6 and the bottom end of the crossbeam 7 are connected to each other, a Z-axis screw electric linear module 10 is mounted on the surface of the crossbeam 7, a convex plate 11 is mounted on the movable end of the Z-axis screw electric linear module 10, and electric grippers 12 are mounted on both sides of the surface of the convex plate 11, and the electric grippers 12 are used to pick up the workpiece in the lower groove;

[0023] When the electric dual-axis moving unit is working, the Y-axis screw electric linear module 6 drives the crossbeam 7, the slide 9, the Z-axis screw electric linear module 10 and other components to move in the Y-axis direction. When the electric clamp 12 moves to the top of the workpiece, the Z-axis screw electric linear module 10 drives the embossed plate 11 and the electric clamp 12 to rise and fall in the Z-axis direction, that is, the electric clamp 12 can be driven downward until the electric clamp 12 contacts the workpiece retained in the lower groove. At this time, the clamp of the electric clamp 12 expands to pick up the workpiece, which reduces the workers' frequent manual mold separation and workpiece picking operations, reduces the workers' physical labor, and reduces the risk of injury;

[0024] An X-axis screw electric linear module 8 is installed on one side of the surface of the crossbeam 7, and a slide 9 is installed on the movable end of the X-axis screw electric linear module 8.

The slide 9, the embossed plate 11, the electric clamp 12 and other components are driven to move in the X-axis direction by the X-axis screw electric linear module 8. When the lower mold 4 is replaced, the picking point of the electric clamp 12 can be actively adjusted according to the stamping point, which provides convenience for the staff's unloading operation;

[0025] A dovetail guide rail 501 is installed on one side of the top end of the C-shaped base plate 5, and a sliding sleeve 502 is installed on one side of the bottom end of the crossbeam 7. The sliding sleeve 502 and the dovetail guide rail 501 are slidably matched.

At this time, the sealing cover after stamping and curling is retained in the lower groove, and the hydraulic lifting unit 2 pulls the upper mold base 3 to reset, so as to prevent the upper mold base 3 from hindering the movement of the crossbeam 7, the embossed plate 11 and other components. At this time, the staff turns on the electric two-axis moving unit at the top of the C-shaped bottom plate 5 again, and the electric two-axis moving unit drives the positions of the embossed plate 11, the electric clamp 12 and other components on the Y and Z axes, that is, the electric two-axis moving unit controls The embossed plate 11 and the electric clamp 12 move to just above the workpiece, and the electric biaxial moving unit drives the embossed plate 11 and the electric clamp 12 downward, so that the electric clamp 12 picks up the workpiece in the lower groove. When the electric clamp 12 picks up the workpiece, the electric biaxial moving unit actively resets, and then the electric clamp 12 completes the release of the workpiece. This device enables the workpiece to be accurately grasped and removed by the electric clamp 12 immediately after the stamping is completed, without waiting for human intervention, reducing the downtime of the production line, and achieving production continuity and efficiency. At the same time, the introduction of the electric clamp 12 and the electric biaxial moving unit helps to improve work safety, reduce the workers' frequent manual mold separation and workpiece picking operations, and reduce the risk of accidents caused by human factors.
