Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a stamping device and stamping method for a power supply protective top cover. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0003] The production of power supply protective covers also requires stamping. During stamping, the bending and punching processes are usually separated. To facilitate positioning during bending, the material is usually punched first, and then bent. However, scrap is generated after punching. Although most of the scrap falls off the scrap outlet and does not affect subsequent parts, some small scrap pieces often adhere to the material and the mold. During the bending process, these small scrap pieces are easily pressed together with the material, resulting in defective parts and seriously affecting production efficiency. Furthermore, separating the bending and punching processes requires two positioning steps, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping device and stamping method for a power supply protective top cover, so as to solve the problems mentioned in the background art.

At the same time, the setting of the cleaning mechanism allows the punching rod to be automatically cleaned after the punching process is completed, without the need for additional cleaning. This greatly improves the production efficiency and yield rate in the manufacturing of power supply protective top covers, and is worthy of widespread promotion. Attached Figure Description

[0034] Please see Figure 1-4 The present invention provides a technical solution:

[0035] A stamping device for manufacturing a power supply protective top cover, as shown in the attached instruction manual. Figure 1 As shown, the stamping device includes:

[0036] The base frame includes an upper mold 1 and a lower mold 2. The upper mold 1 is used to install the bending block 3, and the lower mold 2 is used to install and position the material.

The stripping spring 13 is a compression spring. The moving plate 12 is used to separate the material from the bending block 3.

[0040] A cleaning assembly is used to clean the area around the holes when the unloading assembly is working. The cleaning assembly includes a suction mechanism, a conduit 14, and a blowing mechanism. The conduit 14 is a rubber hose. The suction mechanism is located on the bending block 3, and the blowing mechanism is located on the punching rod 9. The suction mechanism is arranged around the bending block 3, and the blowing mechanism is arranged around the punching rod 9. The blowing mechanism is arranged linearly from top to bottom. The suction mechanism and the blowing mechanism are connected to each other through the conduit 14. The conduit 14 is used to transfer air from the suction chamber 24 to the blowing pipe 32. The suction mechanism is used to collect air for the blowing mechanism, and the blowing mechanism is used to blow air to clean the area around the holes. The bending block 3 has a mounting groove 15 for mounting the suction assembly. The side wall of the mounting groove 15 has a suction hole 16 for connecting outside air to the suction chamber 24.

The two ends of the air blowing pipe 32 are respectively connected to the teeth of the rotating gear 30 and the guide tube 14. The air blowing pipe 32 is used to transmit air.

[0043] A stamping method for using the above-described stamping apparatus includes the following steps:

[0044] A. Place the material at the predetermined position between the upper mold 1 and the lower mold 2;

[0045] B. Activate the lifting assembly to shorten the distance between the upper mold 1 and the lower mold 2, thereby stamping the material and bending it.

[0046] C. After the upper mold 1 and the lower mold 2 move to the set position, the punching rod 9 starts to punch the material.

[0047] D. When the punching rod 9 moves downward, the suction push rod 20 will move synchronously with the punching rod 9 through the synchronous connecting rod 18, thereby drawing air into the suction chamber 24.

[0048] E. After punching is completed, the punching rod 9 moves upward, and through the cooperation of the gear rod 21, rack 1 25 and rack 2 26, the sealing block 27 discharges the air in the suction chamber 24 through the blowing pipe 32.

[0049] F, when the punching rod 9 moves upward, the rotating gear 30 starts to drive the air blowing pipe 32 to rotate and blow air around the punch to clean it.

[0050] Working principle: During use, the punching rod 9 is activated to punch the bent material. When the punching rod 9 moves downward, the suction push rod 20 moves downward simultaneously through the synchronous connecting rod 18. At this time, rack 1 25 moves downward, and after transmission by the gear on gear rod 21, rack 26 moves upward, driving the sealing block 27 to move upward. At this time, air enters the suction chamber 24. After punching is completed, the upper mold 1 is slowly lifted. At this time, the stripping spring 13 rebounds, and the moving plate 12 separates the material and the bent block 3. Then the punching rod 9 is retracted. When the punching rod 9 moves upward to reset, the suction push rod 20 moves downward through the synchronous connecting rod 18. Rod 20 moves upward, and rack 25 also moves upward. Through the transmission of the gear, rack 26 moves downward, thereby driving the sealing block 27 to expel the gas in the suction chamber 24. The expelled air blows out the waste material between the bending block 3 and the material. Then, the hydraulic cylinder 7 is activated to adjust the distance between the hydraulic sleeve rod 5 and the hydraulic push rod 6 so that the bending block 3 bends the material. At this time, the stripping spring 13 is compressed, and the stripping connecting rod 11 is inserted into the through hole 10. After the bending process is completed, the hydraulic cylinder 7 is activated to widen the distance between the hydraulic sleeve rod 5 and the hydraulic push rod 6. At this time, the stripping spring 13 rebounds, and the moving plate 12 separates the material from the bending block 3.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
