DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-4 , an automatic stamping equipment for a motor housing, comprising a stamping base 1, the stamping base 1 is the basic structure of the entire equipment, used to support all other components and keep them stable, a plurality of groups of supporting legs 2 are fixedly connected to the bottom of the stamping base 1 to increase its stability and ensure that the equipment does not move or shake during operation, a plurality of groups of hydraulic rods 3 are connected to the same stamping plate 4 at the top of the stamping base 1, a stamping die seat 5 is connected to the bottom of the stamping plate 4, the design of the stamping die seat 5 is customized according to the shape and size of the motor housing to ensure that each stamping can accurately form the required component shape, a processing groove 6 corresponding to the stamping die seat 5 is provided on the stamping base 1 to ensure that the stamping die seat 5 can accurately contact the workpiece during operation, a feeding port 21 connected to the processing groove 6 is provided on the stamping base 1 to discharge the completed workpiece, a collecting frame 22 is provided at the bottom of the stamping base 1 to collect the workpiece or waste discharged through the feeding port 21, the stamping plate 4 is connected to a movable rod 13 through an extrusion mechanism, the movable rod 13 is connected to a clamping mechanism, and the clamping mechanism is connected to a feeding mechanism.

[0018] The extrusion mechanism includes two piston boxes 7 fixedly connected to the top of the stamping base 1 and symmetrically arranged. The inner wall of the piston box 7 is slidably connected to a piston plate 9. The top of the piston plate 9 is fixedly connected to a piston rod 8. The piston rod 8 passes through the top of the piston box 7 and is fixedly connected to the bottom of the stamping plate 4. When the hydraulic rod 3 pushes the stamping plate 4 to move downward, the piston rod 8 moves downward accordingly, driving the piston plate 9 to slide inside the piston box 7, further increasing the stamping force. The bottom of the piston box 7 is connected to a connecting pipe 10, so that the air in the piston box 7 can flow, thereby ensuring the smooth sliding of the piston plate 9.

[0019] The clamping mechanism includes two air pressure chambers 11 opened on the stamping base 1 and connected to the processing groove 6. The end of the connecting pipe 10 away from the piston box 7 is connected to the air pressure chamber 11. The inner wall of the air pressure chamber 11 is slidably connected with a movable plate 12. The outer wall of the movable plate 12 is fixedly connected to the end of the movable rod 13. The end of the movable rod 13 away from the movable plate 12 is fixedly connected with a clamping plate 14. The design of the clamping plate 14 adopts high-strength material to withstand higher clamping force and maintain good wear resistance. The clamping plate 14 is located in the processing groove 6, and the clamping plate 14 and the processing groove 6 are tightly matched to ensure the stability and accuracy of the workpiece during the clamping process.

[0020] The unloading mechanism includes two placement cavities 15 opened on the stamping base 1 and connected to the processing groove 6. These placement cavities 15 are connected to the processing groove 6. The inner wall of the placement cavity 15 is slidably connected with a movable plate 16, and the outer wall of the movable plate 16 is connected with a movable sleeve plate 17. The design of the movable plate 16 and the movable sleeve plate 17 can ensure the precise positioning and rapid discharge of the material during the stamping process, thereby improving the production efficiency and product quality. The movable rod 13 is connected to the movable plate 16 through a connecting rod 20. The material of the connecting rod 20 can be selected from high-strength alloy steel, so that when the movable rod 13 moves up and down, the connecting rod 20 can drive the movable plate 16 to perform corresponding horizontal movement, thereby driving the movable sleeve plate 17 to slide in the placement cavity 15.

[0021] The outer walls of the movable rod 13 and the movable plate 16 are fixedly connected with connecting blocks so that they can slide in the placement cavity 15. The outer walls of the connecting blocks are fixedly connected with pins. Pin holes are provided at both ends of the connecting rod 20. The inner walls of the pin holes are rotatably sleeved with the pins. The stamping base 1 is provided with an active cavity adapted to the connecting rod 20, which ensures that the connecting rod 20 will not interfere with other parts when moving.

[0022] An elastic spring 18 is provided between the end of the movable plate 16 and the inner bottom of the movable sleeve plate 17. The function of the elastic spring 18 is to provide a certain buffering and resetting function during the movement. The outer wall of the movable plate 16 is fixedly connected to two symmetrically arranged limit blocks 19. These two limit blocks 19 play a role in limiting the movement range of the movable plate 16 during the operation of the equipment. The inner wall of the movable sleeve plate 17 is provided with two limit grooves 23 adapted to the limit blocks 19, and the inner wall of the limit groove 23 is slidably connected to the outer wall of the limit block 19.

[0023] The specific working principle of the present invention is as follows: In actual operation, when this device is used, the operator first places the raw material to be stamped in the processing groove 6 on the stamping base 1. Then, multiple groups of hydraulic rods 3 drive the stamping plate 4 to move downward until the stamping die base 5 connected to the bottom of the stamping plate 4 contacts the raw material. The stamping plate 4 applies pressure to the raw material under the push of the hydraulic rods 3 to complete the stamping of the basic shape of the motor housing.

[0024] In order to achieve more precise and efficient material processing, during the downward movement of the stamping plate 4, the extrusion mechanism on the stamping plate 4 will be started at the same time, and the clamping mechanism connected to the movable rod 13 will begin to function. The clamping plate 14 can effectively fix the raw material through the coordinated action with the movable rod 13 to prevent displacement or deformation during the stamping process.

[0025] After the stamping is completed, the unloading mechanism is immediately activated. The stamping plate 4 moves upward under the push of the hydraulic rod 3, driving the piston rod 8 to move upward. Since the movable plate 12 is affected by the air pressure, it moves outward, causing the movable rod 13 to move. Since the movable rod 13 moves, it drives the movable plate 16 to move through the connecting rod 20. Since the movable plate 16 is provided with a limit block 19, the limit block 19 slides in the limit groove 23, driving the movable sleeve plate 17 to move outward, thereby facilitating the stamping of the motor housing from the unloading port 21. At the same time, when the next stamping is needed, the movable plate 16 moves relatively, and the movable sleeve plate 17 is tightly pressed against each other under the action of the elastic spring 18.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
