Working principle: When it is necessary to punch holes on the plate, first place the plate on the storage board so that the position to be punched is directly below the punch. Then start the motor to drive the first rotating shaft to rotate, which will drive the elliptical cam to rotate. When the small head of the elliptical cam contacts the contact wheel, it will squeeze the contact wheel downwards, thereby driving the lifting rod to move downward. As a result, the punch will be driven to move downward, so that the punch will punch holes in the plate. When punching is completed on the plate, when the large head of the elliptical cam contacts the contact wheel, the lifting rod will move upward due to the action of the spring, thereby driving the punch to move upward. At the same time, the motor drives the first shaft to rotate, which also drives the second gear to rotate. At this time, the second gear meshes with the first gear, thereby driving the first gear to rotate, thereby driving the third shaft to rotate, thereby It will drive the small pulley to rotate, which will drive the flat belt to rotate, which will drive the large pulley to rotate, which will drive the second shaft to rotate, which will drive the third gear to rotate, which will drive the rack to move downward. As a result, the bracket will be driven to move downward, which will drive the pressing block to move downward. The pressing block will press the plate well. When the punching is completed on the plate, the motor will drive the first rotating shaft to rotate, which will also drive the second gear to rotate. When the second gear cooperates with the first gear, the pressing block continues to press the plate, so it is better to pull out the punch from the plate to prevent the plate from moving upward. When the punch resets and the pressing block resets, the motor stops working. Then take out the punched plate. Then repeat the above steps continuously, more plates will be punched.

Because there is a first groove on the top of the storage board, the first groove is located in the middle of the top of the storage board, the first groove is located directly below the pressing block, the first groove is in the shape of a cuboid, and the length of the first groove is 80cm.

Iron waste frame, the iron waste frame is located directly below the storage plate, and the iron waste frame is located directly below the through hole, so when the plate is punched, the electromagnet is powered on, and the electromagnet will attract the iron waste frame live, so that the waste produced during punching can be dropped to the iron waste frame through the through hole, and rubbish can also be thrown in at the same time.

Because it also includes a fan, the top of the bracket is equipped with a fan, the fan is located on the right side of the top of the bracket, the material of the fan casing is plastic, the color of the fan casing is white, the power of the fan is 3000W, and the fan has three stalls gear, so when the plate is punched, start the fan to work, so that the dust generated during punching can be blown away.

Because it also includes a reinforcing rib, a reinforcing rib is provided between the lower left side of the second support rod and the left side of the bottom of the top plate, and the angle between the right side of the reinforcing rib and the bottom of the top plate is 30°, and the material of the reinforcing rib is stainless steel. The inside of the reinforcing rib is hollow, so the second support rod can be fixed more firmly.

Because it also includes a rubber pad, the bottom of the pressing block is provided with a rubber pad, the upper surface of the rubber pad is in contact with the lower surface of the pressing block, the rubber pad is located directly above the storage board, the material of the rubber pad is natural rubber, and the shape of the rubber pad is It is U-shaped, and the thickness of the rubber pad is 2.5cm, so it can effectively prevent the board from being damaged by the pressing block.

Because it also includes electric suction cups, there are second grooves left and right symmetrical on the storage plate at the bottom of the first groove, and electric suction cups are provided in the middle of the bottom of the second groove on the left and the second groove on the right. The size of the electric suction cup on the side and the electric suction cup on the right are equal, so when the plate is punched, start the electric suction cup to work, and the electric suction cup will suck the plate, so that the plate is fixed more firmly.
