[0002] A nut is a cap that is screwed together with a bolt or a screw to fasten something together. It is a component that all manufacturing machinery must use. It is divided into several types, such as carbon steel, stainless steel, and nonferrous metals (such as copper), according to the different materials. When processing nuts, a stamping machine is required. Stamping is a forming method that relies on a press and a mold to apply external force to plates, strips, pipes, and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0016] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0017] 1. The present invention provides a stamping system based on nut processing, which adopts the cooperation of an adjusting mechanism, a connecting block, a lower linkage rod, a screw block, an upper linkage rod, a bearing platform, a sleeve, a straight rod, a screw, a knob, a lower mold, and an upper mold. The screw is driven to rotate by rotating the knob, and the screw drives the screw blocks at both ends to move toward or away from each other. The screw block drives the movement of the upper linkage rod and the lower linkage rod, the upper linkage rod drives the bearing platform to move up and down, and the bearing platform drives the lower mold to move up and down, thereby adjusting the distance between the lower mold and the upper mold, adjusting the depth of stamping, and improving adaptability.

The lower mold is driven downward by stamping, and the lower mold drives the bearing plate to move downward. The bearing plate drives the clamping block to move downward and squeezes the air bag to generate elastic force. When the clamping block contacts the clamping slot, the elastic part restores the elastic force to drive the clamping block to be clamped in the clamping slot for fixation, thereby utilizing the elastic force of the air bag and the descending energy of the bearing plate to buffer the force of stamping. After the stamping is completed, the clamping block is pressed, and the clamping block drives the transmission rod to move, and the transmission rod drives the limit plate to move. The limit plate stretches the elastic part to generate elastic force, and at the same time, the air bag restores the elastic force to drive the bearing plate to move up and bounce back to its original position. At the moment of rebounding to the origin, the stamped workpiece has an instantaneous upward inertia, and the force of inertia separates the workpiece from the lower mold, which is convenient for removing the workpiece, and the clamping block is squeezed on the inner wall of the bearing platform, and the elastic part is in a compression stage to facilitate the ejection of the next movement of the clamping block.

[0019] 3. The present invention provides a stamping system based on nut processing, which adopts the cooperation of a jet mechanism, a chassis, a rechargeable power supply, a jet pump, a hose, an air nozzle, an air intake pipe, a curved plate, a pulley, a switch, a pressure rod, an elastic sheet, an upper mold and a lower mold. The curved plate is driven downward by the upper mold. When the pulley on the curved plate moves downward and contacts the elastic sheet, the pulley squeezes the elastic sheet to deform, and the elastic sheet squeezes the pressure rod to move. The pressure rod presses the switch, so that the rechargeable power supply starts the jet pump, and the air intake pipe draws outside air and sprays it on the inside of the lower mold through the air nozzle, and the workpiece placed in the lower mold is blown to remove dust. When the pulley continues to move downward and separates from the elastic sheet, the switch is disconnected. When the stamping is completed and the upper mold moves upward, the pulley will contact the elastic sheet again, so that the air nozzle removes dust from the inside of the stamped lower mold to prevent dust from affecting the next stamping. In this way, there is no need for workers to start the dust removal device, and the overall linkage of the device is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is a detailed description of the working principle of the stamping system based on nut processing.

[0035] like Figure 1-6As shown, when in use, the screw rod 28 is driven to rotate by rotating the knob as needed, and the screw 28 drives the screw blocks 23 at both ends to move toward or away from each other, and the screw blocks 23 drive the upper linkage rod 24 and the lower linkage rod 22 to move, and the upper linkage rod 24 drives the bearing platform 25 to move up and down, and the bearing platform 25 drives the lower mold 3 to move up and down, so as to adjust the distance between the lower mold 3 and the upper mold 6, and then the workpiece is placed in the lower mold 3, and the hydraulic press 5 is started to drive the upper mold 6 to move downward, and the upper mold 6 moves downward to drive the curved plate 77 to move downward, and when the pulley 78 on the curved plate 77 moves downward and contacts the elastic sheet 711, the pulley 78 squeezes the elastic sheet 711 to deform, and the elastic sheet 711 squeezes the pressure rod 710 to move, and the pressure rod 710 presses the switch 79, so that the rechargeable power supply 72 starts the jet pump 73, and the air inlet pipe 76 draws external air, and sprays it on the inside of the lower mold 3 through the air nozzle 75, so as to blow and remove dust from the workpiece placed in the lower mold 3, and the upper mold 6 is used.
