[0036] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0037] like Figure 1 This is a structural schematic diagram of the utility model, an automatic feeding and shaping machine for stamped outer ring needle roller bearings, comprising a feeding mechanism 1 and a shaping mechanism 2.

[0038] like Figure 1 , Figure 2 As shown, the feeding mechanism 1 is used to convey the workpiece to be shaped to the shaping mechanism 2, the output end of the feeding mechanism 1 is connected to the input end of the shaping mechanism 2, and the feeding mechanism 1 is a vibrating plate;

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, the shaping mechanism 2 includes a frame 21, a shaping die 22, a material pushing assembly 223, a fixing assembly 24 and a material punching assembly 25;

[0040] like Figure 2 , Figure 3 As shown, the shaping die 22 is installed on the frame 21, and the shaping die 22 has a shaping hole 221 for regularizing the workpiece, and the shaping die 22 and the frame 21 are fixedly connected;

[0041] like Figure 2 , Figure 3 As shown, the pusher assembly 223 is installed on the shaping die 22, and is used to push the workpiece conveyed by the feeding mechanism 1 to the shaping hole 221. The pusher assembly 223 includes a pusher power member 2231, a pusher block 232 and a stopper 233.

[0042] The stopper 233 is fixedly connected to the shaping die 22. The stopper 233 is used to block the workpiece conveyed from the feeding mechanism 1 so that the workpiece stays at the pushing end of the pushing assembly 223. The stopper 233 has a sensor for detecting whether the workpiece conveyed by the feeding mechanism 1 reaches the pushing channel 234.

[0043] The output end of the feeding mechanism 1 extends to the shaping die 22, and a material pushing channel 234 is formed between the output end of the feeding mechanism 1 and the stopper 233. The material pushing block 232 is located in the material withdrawing channel 234.

[0044] The material pushing power piece 2231 is fixedly connected to the shaping mold 22. The material pushing power piece 2231 can be a cylinder or other power pieces such as a push rod. The material pushing power piece 2231 is used to provide power for the movement of the material pushing block 232. The material pushing end of the material pushing power piece 2231 is fixedly connected to the material pushing block 232.

[0045] The pushing block 232 is used to receive the workpiece transported to the pushing channel 234 by the loading mechanism 1 and to prevent the workpiece on the loading mechanism 1 from falling during the pushing process. The pushing block 232 has a pushing groove 2321 for accommodating the workpiece on its end face close to one end of the workpiece. The pushing groove 2321 has a V-shaped structure, which can receive the workpiece and prevent the workpiece from deviating during the pushing process.

[0046] like Figure 2 , Figure 3 As shown, the fixing assembly 24 is installed on the shaping die 22 , and the fixing assembly 24 is used to clamp the workpiece pushed by the pushing assembly 223 and align the workpiece with the shaping hole 221 .

[0047] The fixed component 24 includes a fixed limit block 241 and a movable limit block 242. The fixed limit block 241 is fixedly connected to the shaping mold 22. The movable limit block 242 is elastically connected to the shaping mold 22 so that the movable limit block 242 and the fixed limit block 241 clamp the workpiece. The distance between the fixed limit block 241 and the movable limit block 242 is smaller than the size of the workpiece. A fixed channel 243 is formed between the fixed limit block 241 and the movable limit block 242. The shaping hole 221 is located in the fixed channel 243, and the shaping hole 221 is connected to the fixed channel 243. The fixed channel 243 is connected to the pushing end of the pushing component 223, and the input end of the fixed channel 243 is connected to the output end of the pushing channel 234.

[0048] The fixing assembly 24 also includes a mounting block 244 and a spring 245. The mounting block 244 is fixedly connected to the shaping mold 22. A sliding groove 2441 is provided on the mounting block 244 for allowing the movable limit block 242 to move. The movable limit block 242 is slidably installed in the sliding groove 2441. One end of the spring 245 abuts against the movable limit block 242, and the other end abuts against the mounting block 244. A limiting groove is provided on the side wall of the sliding groove 2441. The movable limit block 242 has a card block matching the limiting groove. The card block is slidably arranged in the limiting groove. The design of the limiting groove and the card block can limit the movement of the movable limit block 242 to prevent it from slipping or excessive movement.

[0049] A limiting groove 2421 for accommodating a workpiece is provided on one end of the movable limiting block 242 close to the shaping hole 221 . The limiting groove 2421 can provide positioning for the workpiece so that the workpiece stays above the shaping hole 221 , and the workpiece and the shaping hole 221 remain coaxial.

[0050] The fixed limit block 241 has a fixed introduction surface 2411 on its end face near the movable limit block 242, which expands away from the shaping hole 221; the movable limit block 242 has a movable introduction surface 2422 on its end face near the fixed limit block 241, which expands away from the shaping hole 221; and both the fixed introduction surface 2411 and the movable introduction surface 2422 are located at the input port of the fixed channel 243; and both the fixed introduction surface 2411 and the movable introduction surface 2422 are arc-shaped surfaces, so that the workpiece can easily enter the solid channel 243.

[0051] like Figure 1 As shown, the punching assembly 25 is fixedly connected to the frame 21, and the punching assembly 25 is used to apply pressure to the workpiece at the shaping hole 221 and make it pass through the shaping hole 221. The punching assembly 25 includes an impact head and a punching power piece, and the output end of the punching power piece is fixedly connected to the impact head. The punching power piece is used to provide power for the impact head to approach or move away from the workpiece at the shaping hole. The punching power piece can be a hydraulic cylinder, or a crank mechanism, etc.

[0052] The shaping machine of the present application detects the position of the workpiece through multiple sensors and controls the working condition of the equipment. When in use, the loading mechanism 1 is started to arrange the workpieces neatly and transport them to the pushing channel 234. After the sensor on the stop block 233 detects that there are workpieces in the pushing channel 234, the pushing power piece 2231 is started to make the pushing block 232 move and approach the fixed channel 243. The pushing block 232 pushes the workpiece into the fixed channel 243 until the workpiece arrives between the limit groove 2421 and the fixed limit block 241, and then the pushing power piece 2231 retracts to make the pushing block 232 retreat. During this process, the pushing block 232 passes over the unloading port of the loading mechanism 1, so that the workpiece on it cannot continue to fall until the pushing block 232 retreats to its initial position.

[0053] When the workpiece is transported to the limit groove 2421 and the fixed limit block 241, under the elastic force of the spring, the fixed limit block 241 and the movable limit block 242 clamp the workpiece and make the workpiece stay above the shaping hole 221, the punching assembly 25 starts to apply pressure to the workpiece so that the workpiece passes through the shaping hole 221 and completes the shaping of the workpiece in the process of passing through the shaping hole 221.

[0054] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
