Description

Technical Field

[0001] This invention relates to the field of wheel hub processing technology, specifically a punching device for processing automotive wheel hub parts. Background Technology

[0002] A car wheel hub is a component used to support the tire when mounted on the axle. It is usually made of materials such as steel and aluminum alloy. It has the functions of supporting the overall weight of the vehicle, mounting the axle, buffering external impacts, enabling the tire to contact the road surface, and bearing lateral loads, driving force and braking torque.

[0003] Car wheel hubs are typically divided into inner and outer rings. During the production process, the inner ring of a car wheel hub needs to undergo stretching, forming, and punching. However, most punching devices currently in use can only punch the inner ring of the wheel hub. This requires pre-stretching and forming the raw material before transferring it to the punching device for punching. The transfer process takes time and can affect processing efficiency. To address these issues, the inventor proposes a punching device for processing car wheel hub parts. Summary of the Invention

[0048] By adopting the above technical solution, the transport pump 211 is able to transport the medicine.

[0049] An installation strip 402 is fixedly installed between the vertical plates 401. An installation rod 403 is rotatably installed inside the installation strip 402. The installation rod 403 and the transmission rod 214 are driven by a synchronous pulley and a synchronous belt. The top end of the installation rod 403 is rotatably set inside the support box 201. A rotating strip 404 is fixedly installed at the bottom end of the installation rod 403. A guide rod 406 is fixedly installed at one end of the installation rod 403 on the lower surface of the rotating strip 404. The bottom end of the guide rod 406 is slidably inserted into the push frame 405.

[0050] By adopting the above technical solution, the transmission rod 214 can drive the nozzle 407 to move.

[0051] Working principle: First, the raw material is placed on the processing plate 301. Then, the first electric cylinder 302 is turned on to move the fixed frame 303. The movement of the fixed frame 303 moves the limiting post 304, so that the outer surface of the limiting post 304 contacts the outer surface of the raw material to clamp and position the raw material. After positioning, the second electric cylinder 308 is turned on to move the moving frame 309. The movement of the moving frame 309 moves the swing plate 310, which in turn moves the moving plate 305. The moving plate 305 moves to the bottom of the processing plate 301. Then, the transport pump 211 is turned on to transport the agent inside the storage tank 210 to the nozzle 407 through the transport pipe 212 for spraying. The agent is sprayed onto the upper surface of the raw material.

[0052] Next, turn on motor 111 to drive the rotating rod 109 to rotate. The rotation of the rotating rod 109 drives the rotating plate 110 to rotate, causing the rotating plate 110 to rotate one-quarter of a turn. The rotation of the rotating plate 110 drives the mounting plate 102 to move, causing the mounting plate 102 to move upward. The movement of the mounting plate 102 drives the fixed arm 105 to move, and the movement of the fixed arm 105 drives the fixed ring 104 to move. The movement of the fixed ring 104 drives the moving column 103 to move. At the same time, the movement of the fixed arm 105 drives the moving arm 106 to move, and the movement of the moving arm 106 drives the lower mold 107 to move, so that the upper surface of the lower mold 107 contacts the lower surface of the raw material.

[0053] Then, opening the hydraulic telescopic rod 217 moves the push plate 222, which in turn moves the locking block 223, which in turn moves the upper mold, bringing it into contact with the upper surface of the raw material to stretch it. The push plate 222 also moves the toothed plate 224, which meshes with the second gear 225, causing the second gear 225 to rotate. The rotation of the second gear 225 then rotates the rotating rod 213, which in turn rotates the first bevel gear 215, which in turn rotates the second bevel gear 216. The rotation of the second bevel gear 216 drives the transmission rod 214 to rotate, which in turn drives the mounting rod 403 to rotate. The rotation of the mounting rod 403 drives the rotating bar 404 to rotate, which in turn drives the guide rod 406 to perform a quarter-circular motion. The circular motion can be decomposed into lateral movement and longitudinal movement. When the guide rod 406 moves laterally, it is slidably positioned inside the push frame 405. When the guide rod 406 moves longitudinally, it drives the push frame 405 to move. The movement of the push frame 405 drives the nozzle 407 to move, thus preventing the nozzle 407 from obstructing the upper mold.

[0054] Finally, the second motor 208 is turned on, driving the vertical rod 205 to rotate. The rotation of the vertical rod 205 drives the first gear 206 to rotate, which in turn drives the gear ring 204 to rotate. The rotation of the gear ring 204 drives the mounting column 202 to rotate, which in turn drives the fixing bar 226 to move. The movement of the fixing bar 226 drives the telescopic bar 227 to move, which in turn drives the upper mold to move, thus enabling the upper mold to be replaced. The rotation of the mounting column 202 also drives the moving column 103 to rotate, which in turn drives the fixing arm 105 to move. The movement of the fixing arm 105 drives the moving arm 106 to move, which in turn drives the lower mold 107 to move, enabling the lower mold 107 to be replaced. This allows for subsequent forming and punching of the raw material, avoiding the need to first stretch and form the material before transferring it for punching, thus improving processing efficiency.

[0055] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
