[0002] The keyboard metal shell is an important part of the keyboard structure. It is usually made of metal material and has a series of characteristics and advantages. The keyboard metal shell refers to the metal material structure wrapped between the internal electronic components and the external keys of the keyboard. It plays the role of protecting the internal electronic components, supporting the keys and providing the user with a sense of touch. When punching the keyboard metal shell, workers need to use a punching device. In the existing punching device for the keyboard metal shell, under the long-term stamping of the punch, the temperature of the punch rises due to frequent impact and friction. The increase in temperature will accelerate the wear and aging speed of the punch. Therefore, it is necessary to stop the machine to let the punch cool naturally, and the cooling time is relatively long, resulting in a significant reduction in the overall production efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 - 5 As shown, a keyboard metal shell punching device comprises a base 1, a right angle bracket 2 is fixedly mounted on one side of the upper surface of the base 1, a cylinder 3 is fixedly mounted on the upper surface of the right angle bracket 2, and a punch 5 is fixedly mounted on the output end of the cylinder 3 through the right angle bracket 2 and through a support base 4;

[0024] A stamping die 6 is fixedly installed in the middle of the upper surface of the base 1;

[0025] A cooling assembly 7 for cooling the punch 5 is provided at the top of the right-angle frame 2 .

[0026] The cooling assembly 7 includes two vertical poles 701, and the two vertical poles 701 are respectively fixedly installed on both sides of the bottom of the right-angle frame 2. A ring plate 702 is fixedly installed at the lower ends of the two vertical poles 701. A connecting ring 703 is arranged inside the ring plate 702. A cavity 704 for air flow is opened inside the connecting ring 703. An air inlet pipe 705 is fixedly installed on the upper surface of the connecting ring 703. A plurality of nozzles 706 are fixedly installed on the inner wall of the ring plate 702. The air inlet pipe 705 and the inner cavity of the nozzle 706 are both connected to the cavity 704.

[0027] The staff fixes the shell on the surface of the stamping die 6, and then starts the cylinder 3 so that its output end drives the punch 5 to descend, so that the punch 5 stamps the shell. After the punch 5 is used for a long time, the staff controls the punch 5 to move to its original position, and then injects cooling gas into the air inlet pipe 705. After the cooling gas enters the cavity 704, it finally flows to the position of the punch 5 through the nozzle 706, so that the cooling gas cools the punch 5, accelerates the cooling process of the punch 5, and shortens the time required for cooling the punch 5, thereby greatly improving the overall production efficiency.

[0028] The inner wall of the annular plate 702 is equipped with a bearing 8, and the connecting ring 703 is rotatably installed inside the annular plate 702 through the bearing 8.

[0029] A number of upright columns 9 are fixedly installed on the lower surface of the connecting ring 703, and an external gear ring 10 is fixedly installed at the lower ends of each upright column 9 together.

[0030] A motor 12 is fixedly installed on the upper surface of the annular plate 702 through a bracket 11. A gear 13 is sleeved on the shaft body of the output shaft of the motor 12, and the gear 13 meshes with the external gear ring 10.

[0031] The staff starts the motor 12, so that its output shaft drives the gear 13 to rotate reciprocally. Under the meshing action of the gear 13 and the external gear ring 10, the connecting ring 703 drives the nozzle 706 to rotate reciprocally with the bearing 8 as a reference, increasing the exhaust range of the nozzle 706 and enhancing the cooling effect.

[0032] In another embodiment of the present utility model, a blower 14 is fixedly installed on the side of the right-angle frame 2 away from the stamping die 6 through a bottom plate 201. One end of the blower 14 is fixedly installed with an air inlet hood 15, one end of the air inlet hood 15 is fixedly installed with an exhaust pipe 16, and one end of the exhaust pipe 16 passes through the right-angle frame 2 and is fixedly connected with the air inlet pipe 705 through a hose 17.

[0033] The hose 17 is a corrugated pipe.

[0034] By setting the blower 14, it can generate cooling gas and transport the cooling gas into the air inlet pipe 705. The corrugated pipe has good elasticity, avoiding breakage when it moves or bends.

[0035] The working principle of the punching device for the metal shell of a keyboard:

[0036] During use, the staff fixes the shell on the surface of the stamping die 6. Then, the staff starts the cylinder 3, and its output end drives the punch 5 to descend, so that the punch 5 punches and forms the shell. After the punch 5 is used for a long time, the staff controls the punch 5 to move back to its original position. Then, cooling gas is infused into the air inlet pipe 705. These cooling gases enter the cavity 704 and finally flow to the position of the punch 5 through the nozzle 706, so that the cooling gas cools the punch 5, accelerating the cooling process of the punch 5. The time required to cool the punch 5 is relatively short, greatly improving the overall production efficiency.

[0037] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
