[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0021] like Figures 1 to 4As shown, a high-speed punching machine with a workpiece protection function includes a base 1, a punching body 3 and a clamping assembly 7. A processing table 2 is arranged on the top surface of the base 1. The base 1, as the base of the entire punching machine, can provide stable support and fixation to ensure the working stability of the entire punching machine. The processing table 2 is used to place the workpiece, and the workpiece can be stably processed on the processing table 2. The punching body 3 is arranged behind the processing table 2. The punching body 3 is the core component of the high-speed punching machine and plays a key role in controlling and coordinating the punching process to ensure that the workpiece can be accurately and stably punched. A crankcase 4 is arranged on the right side of the punching body 3. The crankcase 4 is used to control the movement of the punching body 3. A push rod 5 is arranged at the bottom end of the front side of the punching body 3. The lifting movement of the push rod 5 drives the punching head 6 to perform punching processing. The bottom end surface of the push rod 5 is provided with a punching head 6. The punching head 6 corresponds to the position of the processing table 2. The punching head 6 punches the workpiece on the processing table 2 through a mold;
[0022] The clamping assembly 7 is arranged in the inner cavity of the processing table 2, and the clamping assembly 7 includes a U-shaped splint 701, a telescopic rod 702, a strong spring 703, a clamping strip 704 and a rubber sheet 705. The U-shaped splint 701 is arranged in the inner cavity of the processing table 2, and four groups of U-shaped splints 701 are arranged. One end of the U-shaped splint 701 is meshed with the inner cavity of the processing table 2. The four groups of U-shaped splints 701 can realize the firm clamping of the workpiece to ensure that the workpiece will not move or tilt during the processing. One end of the opposite surface of each two groups of U-shaped splints 701 is connected with a telescopic rod 702, and the two groups of telescopic rods 702 respectively form a connecting bridge between the four groups of U-shaped splints 701 to ensure that each two groups of U-shaped splints 701 correspond to each other, thereby forming a clamping force. The outer surface of the telescopic rod 702 is provided with a strong spring 703, a strong spring The two ends of the force spring 703 are respectively connected to the end points of the opposite surfaces of the two groups of U-shaped clamping plates 701. The strong spring 703 uses its own strong elasticity to tighten the corresponding two groups of U-shaped clamping plates 701 to generate a clamping force to ensure that the workpiece is firmly clamped on the processing table 2. The other ends of each two groups of parallel U-shaped clamping plates 701 are provided with clamping strips 704. The clamping strips 704 increase the clamping area of the U-shaped clamping plates 701 to ensure that the workpiece is firmly clamped during the processing. One side of the opposite surface of the two groups of clamping strips 704 is provided with a rubber sheet 705. The surface of the rubber sheet 705 is arranged in a row with a plurality of dot-shaped protrusions. The rubber sheet 705 uses the dot-shaped protrusions and its own friction to prevent the workpiece from sliding, thereby ensuring that the workpiece is firmly clamped during the stamping process and reducing the movement or tilt of the workpiece caused by improper clamping.
[0023] The front end surface of the processing table 2 is provided with a fixed steel rod 8, and the fixed steel rod 8 is provided with two groups to fix the position of the protective plate 9, increase the stability of the protective plate 9, and ensure that the protective plate 9 will not shake the position of the fixed processing table 2 during the protection process. The opposite surfaces of the two groups of fixed steel rods 8 are provided with protective plates 9, and the surface of the protective plates 9 is transparent. The material of the protective plates 9 is polymethyl methacrylate. The protective plates 9 are made of transparent polymethyl methacrylate material, which can effectively prevent the debris, splashes, etc. generated during the workpiece processing from injuring the operator and protect the safety of the operator. The fixed steel rod 8 and the protective plate 9 are fixed by bolts 10, and four groups of bolts 10 are provided. The outer surfaces of the rod bodies of the two groups of fixed steel rods 8 are provided with threaded holes 11, and four groups of threaded holes 11 are provided. The four groups of bolts 10 correspond to the positions of the four groups of threaded holes 11, and the bolts 10 are meshed with the threaded holes 11. The bolts 10 are meshed with the outer surfaces of the fixed steel rods 8 through the threaded holes 11, ensuring the firm connection between the fixed steel rods 8 and the protective plate 9, and effectively protecting the safety of the operator.
[0024] In summary, if Figures 1 to 4 As shown, the high-speed punching machine with workpiece protection function, when it is necessary to fix the workpiece, the U-shaped clamping plate 701 of the clamping assembly 7 clamps the workpiece, and the corresponding two groups of U-shaped clamping plates 701 are connected by the telescopic rod 702 to ensure that they are on the same horizontal line, and the corresponding two groups of U-shaped clamping plates 701 are tightened by the elasticity of the strong spring 703 itself, so as to form a clamping force, and the other two groups of U-shaped clamping plates 701 are clamped by the same principle. The four groups of U-shaped clamping plates 701 increase the contact area of the U-shaped clamping plates 701 on the workpiece through the clamping strip 704 to ensure that they can adapt to workpieces of different sizes, and balance their clamping force to ensure that the clamping force is evenly distributed on the workpiece, and the rubber sheet 705 uses the dot-shaped protrusions and its own friction to prevent the workpiece from sliding, thereby ensuring that the workpiece is firmly clamped during the stamping process and reducing the movement or tilt of the workpiece due to improper clamping;
[0025] When the high-speed punching machine is working, the operator places the workpiece on the surface of the processing table 2 on the base 1, and clamps the workpiece with the clamping assembly 7. According to the shape of the workpiece, the strong spring 703 uses its own elasticity to adapt to different sizes. The operator sets the parameters of the punching body 3 according to the processing requirements. The crankcase 4 controls the movement of the punching body 3 to move the punching head 6 to a predetermined position. The lifting and lowering movement of the push rod 5 drives the punching head 6 to perform punching processing. The punching head 6 punches the workpiece through the mold. The punching body 3 controls the movement of the punching head 6 to ensure the accuracy and stability of the punching processing. The fixed steel rod 8 fixes the four corners of the protective plate 9 through the engagement of the bolt 10 with the threaded hole 11, so that the protective plate 9 stands upright on the front end face of the processing table 2. When processing, debris and splashes will be generated, which will cause harm to the operator. The protective plate 9 uses transparent polymethyl methacrylate material to block these wastes, and the transparent property allows the staff to view the punching process.
