A motor 26 is mounted at the bottom of the synchronization assembly 24. The output shaft of the motor 26 drives one of the connecting shafts 230 to rotate through the synchronization assembly 24.

[0037] A sliding plate 3 is slidably mounted on the top of the slide groove 20. A groove 30 is formed at the bottom of the sliding plate 3, and two racks 31 are fixed within the groove 30. Two gears 23 are located between the two racks 31, and each gear 23 meshes with its corresponding rack 31. Two symmetrical lower die bases 4 are fixed to the top of the sliding plate 3. A fixing groove 41 is formed on the top of the lower die base 4. A first punching groove 42, a second punching groove 43, and a third punching groove 44 are sequentially formed on the inner bottom wall of the fixing groove 41 along the front-back direction. Bending grooves 45 are formed on both the left and right sides of the fixing groove 41. The first punching groove 42, the second punching groove 43, the third punching groove 44, and the bending groove 45 are all through grooves.

[0038] In the embodiment, the bottom of the lower die seat 4 is provided with a waste discharge groove 40, which is in communication with the first punch groove 42, the second punch groove 43, the third punch groove 44 and the bending groove 45. This design enables the waste generated in the stamping process to be smoothly discharged, avoiding the accumulation of waste affecting the stamping effect and the service life of the die; at the same time, it is also convenient for subsequent waste cleaning work, improving the production efficiency.

[0039] In the embodiment, the inner bottom wall of the chute 20 is fixed with two guide seats 22, and the groove 30 is fixedly connected with two guide rods 32 through bolts, and the two guide rods 32 respectively pass through the two guide seats 22 and are slidably connected with the guide seats 22.

[0042] In the embodiment, the top four corners of the base 2 are fixedly connected with connecting rods 28 through bolts, and the four corners of the top seat 1 are provided with guide holes 10, and the connecting rods 28 pass through the corresponding guide holes 10 and are slidably connected with the guide holes 10. The sliding fit of the connecting rod 28 and the guide hole 10 effectively prevents the deviation and shaking of the top seat 1, improving the stability and precision of the stamping process.

[0043] In the embodiment, the left and right side walls of the sliding plate 3 are fixed with guide rails 34, and the left and right side walls of the chute 20 are provided with guide grooves 21 slidably connected with the guide rails 34. This design further enhances the stability and accuracy of the sliding plate 3 during movement.

[0044] In the embodiment, the first punch 12, the second punch 13 and the third punch 14 are respectively located above the corresponding first punch groove 42, the second punch groove 43 and the third punch groove 44. This design ensures that the stamping process can be accurately performed, thereby helping to improve the stamping precision and consistency of the fuselage shell 5.

[0045] It can be understood that the bottom of the base 2 in the embodiment is fixedly connected with a support 25, the synchronous assembly 24 is installed on the inner side of the support 25, and the motor 26 is fixedly connected with the support 25 through bolts. The support 25 not only plays a supporting and fixing role on the motor 26, but also plays a protection role on the synchronous assembly 24.

[0046] It should be noted that the synchronous assembly 24 in the embodiment includes two belt pulleys, a belt is sleeved between the two belt pulleys, the output shaft of the motor 26 is coaxially connected with one of the belt pulleys through a key, and the other belt pulley is coaxially connected with the bottom of the connecting shaft 230 through a key. This design facilitates the rotation of the gear 23 driven by the motor 26.

[0047] In addition, the bending part 15 in the embodiment is located directly above the bending groove 45. When the top base 1 is pressed down, the bending part 15 can bend the two ends of the body shell 5 to form a folding part 50.

[0048] When the stamping device for the notebook computer shell in the embodiment is used, the user first places the raw materials of the two body shells 5 into the two fixed grooves 41, then operates the hydraulic cylinder to run, the piston rod of the hydraulic cylinder moves downward to drive the top base 1 to move downward, and the top base 1 drives the upper die seat 11, the first punch 12, the second punch 13 and the third punch 14 to move downward. The first punch 12, the second punch 13 and the third punch 14 contact and extrude the body shell 5, and simultaneously pass through the body shell 5 and are inserted into the corresponding first punching groove 42, second punching groove 43 and third punching groove 44. The waste material separated from the body shell 5 falls into the waste discharge groove 40. When the piston rod of the hydraulic cylinder drives the top base 1 to move upward, the first punch 12, the second punch 13 and the third punch 14 are separated from the first punching groove 42, the second punching groove 43 and the third punching groove 44, and the keyboard groove 51, the touchpad groove 52 and the key groove 53 are formed on the body shell 5. When the stamping is completed, the user then connects the power supply of the motor 26, the output shaft of the motor 26 drives the belt pulley to rotate, the belt pulley drives the connecting shaft 230 and the gear 23 to rotate. Since the two gears 23 are engaged, the two gears 23 rotate synchronously. Since the gear 23 is engaged with the rack 31, the rack 31 drives the slide plate 3 to move horizontally. At this time, the slide plate 3 drives the lower die seat 4 carrying the stamped body shell 5 to separate from the bottom of the top base 1, and the lower die seat 4 carrying the un-stamped body shell 5 moves to the position directly below the top base 1. The user stops the power supply of the motor 26, and then the user operates the hydraulic cylinder to run again. The piston rod of the hydraulic cylinder moves downward to drive the top base 1 to move downward, so as to stamp the raw material of the body shell 5 on the other lower die seat 4 to form the body shell 5. Finally, the user can take out the stamped body shell 5.
