Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0016] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0017] In order to solve the above technical problems, Figure 1-3As shown, this embodiment designs an efficient and high-precision punching device, including a base 1, an upper die fixing plate 2, an upper punch 3, a lower concave die 4, a lower punch 5, a first cylinder 6, a second cylinder 7, and a discharge track 8. Two left-right symmetrical support plates 9 are provided on the base 1. The tops of the two support plates 9 are connected by a horizontal plate, which provides a stable structural foundation and is conducive to improving the accuracy and efficiency of punching. The first cylinder 6 is installed above the horizontal plate, and the piston rod of the first cylinder 6 passes through the horizontal plate downward and is connected to the upper punch 3 fixing plate. The upper punch 3 is installed below the upper die fixing plate 2. The two support plates 9 are connected by a horizontal plate. A lower die 4 is fixed between the support plates 9. The second cylinder 7 is fixedly mounted on the base 1 and its piston rod is connected to the lower punch 5 upward. The connection between the upper punch 3 and the first cylinder 6 and the connection between the lower punch 5 and the second cylinder 7 ensures precise control of the punching action. The lower punch 5 can punch the workpiece off the plate, and the upper punch 3 completes the central punching. The specific mold shape can be adjusted according to product requirements without restriction. A conventional punching mold design can be used. The upper and lower cylinder drives ensure the synchronization and consistency of the punching action, effectively avoiding material damage or equipment failure due to improper operation.

[0018] The unloading track 8 is arranged on one side of the lower die 4. Specifically, the unloading track 8 includes a slide rail 81, a baffle 82, and a baffle 83. The slide rail 81 is arranged downwardly in an inclined manner. A baffle 83 is provided on the top of the slide rail 81. A discharge port connected to the unloading track 8 is provided on one side of the concave hole of the lower die 4. The opening of the baffle 83 is docked with the discharge port of the lower die 4. Two baffles 82 are symmetrically arranged on both sides of the slide rail 81. The other side of the lower die 4 is provided with a blowing hole 13, and the blowing hole 13 is connected to an external air supply source. When the workpiece is punched down and formed The workpiece falls into the lower die 4, and the air source connected to the blowing hole blows air, so that the product can be blown to one side of the opening of the discharge track 8. The opening of the shield 83 is precisely connected with the discharge port of the lower die 4 to prevent the workpiece from being blown away, ensuring that the workpiece can be discharged smoothly from the lower die 4. The downward inclined slide rail 81 and the top shield 83 provide a smooth unloading path for the workpiece. The symmetrical setting of the baffle 82 enhances the stability of the workpiece during the unloading process and reduces the possibility of workpiece deviation. The setting of the unloading track 8 realizes the automatic unloading of the formed workpiece, which greatly improves the production efficiency.

[0019] Furthermore, a clamping plate 10 is provided on both sides of the shield 83, and the clamping plate 10 is provided with a U-shaped slot. Two positioning bolts are installed on one side of the lower die 4. The clamping plate 10 is hung on the head of the positioning bolt through the U-shaped slot. The clamping plate 10 is hung on the positioning bolt on the side of the lower die 4. This solution realizes the rapid installation and adjustment of the unloading track 8, and improves the adaptability of the equipment and the convenience of operation.

[0020] Furthermore, support rods are provided on the left and right sides of the upper mold fixing plate 2, and sliders 11 are provided at the ends of the support rods. The support plate 9 is provided with a slide groove that cooperates with the slider 11, which provides precise stroke limit and adjustment capabilities for the stroke of the upper mold fixing plate 2, which is beneficial to improving the punching accuracy, ensuring the stability of the upper mold fixing plate 2 during the punching process, and reducing punching deviations caused by equipment vibration or movement.

[0021] Furthermore, a guide rod 12 is provided on the lower die 4, and the upper die fixing plate 2 is provided with a sliding hole that cooperates with the guide rod 12. The precise cooperation between the guide rod and the sliding hole ensures the stable movement of the die during the punching process and reduces the punching quality problems caused by die offset.

[0022] Based on the above embodiments, Figure 4 As shown, this embodiment further improves the unloading track 8 by making the slide rail 81 of the unloading track 8 into a gradually widened structure in the lower area, which can effectively avoid the possibility of the workpiece getting stuck on the slide rail 81.
