Specific embodiments

[0020] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0021] Among them, the same reference numerals in the drawings all refer to the same components.

[0022] As Figures 1-4 shown, the present utility model provides a shoe upper punching machine, which includes a workbench 1. A placement groove 2 is opened at the top of the workbench 1. A support frame 3 is fixedly installed on the top of the workbench 1. A punching component is arranged on the support frame 3. The punching component includes a hydraulic cylinder 4, a movable plate 5, a guide rod 6, an installation frame 7, a counterweight frame 8, and a punching head 9. A leveling component is movably arranged inside the placement groove 2. The leveling component includes a drive motor 10, a lead screw 11, a slider 12, a limit rod 13, and a rolling roller 14.

[0023] Through the cooperation of the drive motor 10, the lead screw 11, the slider 12, and the limit rod 13, this device drives the rolling roller 14 to roll inside the placement groove 2 to flatten the shoe upper inside the placement groove 2. This design can ensure that the shoe upper reaches a flat state before punching, which is beneficial to the accuracy and consistency of the punching operation. During the punching process, the shoe upper is punched through the cooperation of the hydraulic cylinder 4, the movable plate 5, and the punching head 9. At the same time, through the cooperation of the installation frame 7, the guide rod 6, and the counterweight frame 8, the counterweight frame 8 is used to press and fix the shoe upper, effectively preventing the offset of the shoe upper during the punching process and further improving the punching accuracy.

[0024] Furthermore, a hydraulic cylinder 4 is installed in the middle of the top of the support frame 3. The bottom of the hydraulic cylinder 4 penetrates through the installation frame and is fixedly installed with a movable plate 5. A punching head 9 is arranged in the middle of the bottom of the movable plate 5.

[0025] Furthermore, an installation frame 7 is movably arranged on the top of the movable plate 5. Guide rods 6 are fixedly installed at the four corners of the bottom of the installation frame 7. The bottom of the guide rod 6 penetrates through the movable plate 5, and the guide rod 6 is slidably connected with the movable plate 5. The bottom ends of the guide rods 6 are respectively fixedly connected to the four corners of the top of the counterweight frame 8. The outer dimensions of the movable plate 5, the installation frame 7, and the counterweight frame 8 are the same.

[0026] Further, a driving motor 10 is installed at the top of one side of the workbench 1. Limiting grooves 15 are opened on both sides of the placing groove 2. The output end of the driving motor 10 is provided with a lead screw 11. The other end of the lead screw 11 extends into the interior of the limiting groove 15 and is rotatably connected to the inner wall of one side of the limiting groove 15. A limiting rod 13 is fixedly installed in the other limiting groove 15. A slider 12 is threadedly connected to the outer surface of the lead screw 11. The slider 12 is slidably connected to the outer surface of the limiting rod 13. A rolling roller 14 is rotatably installed between the sliders 12.

[0027] Further, a through groove 16 is opened in the middle of the interior of the placing groove 2. An electric telescopic rod 17 is installed at the middle of the bottom of the workbench 1 through a bracket. The position of the electric telescopic rod 17 is opposite to that of the through groove 16. A top block is fixedly installed at the top of the electric telescopic rod 17. Through the cooperation of the electric telescopic rod 17 and the top block, the shoe upper after the punching work can be pushed out, facilitating the blanking of the shoe upper.

[0028] Further, a controller 18 is arranged on one side of the support frame 3. The signal output end of the controller 18 is connected to the signal input ends of the hydraulic cylinder 4, the driving motor 10, and the electric telescopic rod 17.

[0029] Working principle: When in use, place the shoe upper on the top of the through groove 16, and then drive the lead screw 11 to rotate through the driving motor 10. The rotation of the lead screw 11 will drive the slider 12 on its outer part to move. Then, under the combined action of the limiting rod 13 and the other slider 12, the rolling roller 14 is driven to roll inside the placing groove 2 to flatten the shoe upper inside the placing groove 2. This design can ensure that the shoe upper reaches a flat state before punching, which is beneficial to the accuracy and consistency of the punching operation. Then, drive the movable plate 5 and the punching head 9 to move downward through the hydraulic cylinder 4, and further drive the mounting block 7, the guide rod 6, and the counterweight frame 8 to move downward. On the way down, the counterweight frame 8 will first contact the shoe upper, and press and fix the shoe upper through the counterweight frame 8, effectively preventing the offset of the shoe upper during the punching process and further improving the punching accuracy. Then, the movable plate 5 and the punching head 9 continue to move downward, and the punching head 9 punches the shoe upper. After the punching work is completed, the hydraulic cylinder 4 will return to the initial position, and further drive the movable plate 5, the guide rod 6, the mounting frame 7, the counterweight frame 8, and the punching head 9 to move upward. Then, through the combined action of the electric telescopic rod 17 and the top block, the punched shoe upper is pushed out, facilitating the staff to take out the shoe upper, and then it returns to the initial position.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
