The buckle machine can be used to install the workpiece to be tableted on shoes, hats or leather.

[0003] The button-fastening machine in the prior art does not have a buffer mechanism. During the process of squeezing the workpiece to be punched and installing it on shoes, hats or leather, the workpiece to be punched is easily squeezed and deformed due to the large rigid impact of the button-fastening machine, and sometimes even the shoes, hats or leather are crushed, which increases the destructiveness and significantly affects the installation effect of the workpiece to be punched. In addition, there is no corresponding fixing structure during punching, and the object cannot be stably fixed. Therefore, this application proposes another technical solution to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A high-precision metal sheeting machine in this embodiment includes a fixed base 1, and an adjustment and fixing mechanism is arranged on the top of the fixed base 1.

[0023] In embodiment one, the adjustment and fixing mechanism includes a workbench 2 fixedly installed on the top of the fixed base 1, a brake motor 3 is fixedly installed on the right side of the workbench 2, and a bidirectional screw rod 4 rotatably connected to the workbench 2 is fixedly installed on the output shaft of the brake motor 3. A movable groove is opened on the right side of the workbench 2, and the bidirectional screw rod 4 is threadedly connected to the brake motor 3 through the movable groove, so that the brake motor 3 can drive the bidirectional screw rod 4 to rotate.

[0024] Among them, the outer side of the bidirectional screw rod 4 is threadedly connected with two thread blocks 5, and two thread grooves in opposite directions are provided on the outer side of the bidirectional screw rod 4. The thread block 5 is threadedly connected to the bidirectional screw rod 4 through the thread groove, which facilitates the thread block 5 to slide on the outer side of the bidirectional screw rod 4. A limit rod 6 slidably connected to the workbench 2 is fixedly installed on the top of the thread block 5.

[0025] In this embodiment, a limit groove is provided on the top of the workbench 2, and the limit rod 6 is slidably connected to the workbench 2 through the limit groove, so as to facilitate limiting the limit rod 6. A clamping plate 7 is fixedly installed on the top of the limit rod 6, and a workpiece body 8 to be sliced ​​is movably connected between the two clamping plates 7. A fixing frame 9 is fixedly installed on the top of the fixed base 1.

[0026] In the second embodiment, a buffering film-breaking mechanism is provided on the inner bottom wall of the fixed frame 9, an electric push rod 10 is fixedly installed on the inner bottom wall of the fixed frame 9, a mounting plate 11 is fixedly installed on the output shaft of the electric push rod 10, a mounting box 12 is fixedly installed on the bottom of the mounting plate 11, a buffer spring 13 is fixedly installed inside the mounting box 12, a movable plate 14 is fixedly installed on the bottom of the buffer spring 13, and sliding grooves are provided on the inner walls on the left and right sides of the mounting box 12, and the movable plate 14 is slidably connected to the mounting box 12 through the sliding grooves, which helps the movable plate 14 to move inside the mounting box 12.

[0027] Among them, a stamping plate 15 is fixedly installed at the bottom of the movable plate 14, and the stamping plate 15 is located directly above the workbench 2, which helps the stamping plate 15 to stamp the objects on the workbench 2. A through groove is opened at the bottom of the installation box 12, and the stamping plate 15 is movably connected to the installation box 12 through the through groove, which helps the stamping plate 15 to move. A damper 16 is fixedly connected between the installation plate 11 and the stamping plate 15.

[0028] It should be noted that the high-precision metal sheet punching machine, through the setting of the adjustment and fixing mechanism, uses the brake motor 3 and the bidirectional screw 4 to drive the two clamping plates 7 to move closer to or away from each other, so that the two clamping plates 7 can clamp and fix workpieces 8 of different sizes to be punched, and the electric push rod 10 can drive the stamping plate 15 to punch the workpiece 8 to be punched. At the same time, the buffer stamping plate 15 pushes the movable plate 14 upward, and the movement of the movable plate 14 squeezes and compresses the buffer spring 13, so that the buffer spring 13 reduces the impact force. The damper 16 further reduces the impact force and can also avoid unnecessary shaking of the stamping plate 15, thereby improving the safety and stability of the punching.

[0029] The working principle of the above embodiment is:

[0030] When using the high-precision metal sheeting machine, first place the workpiece 8 to be sheeted on the top of the workbench 2, then start the brake motor 3, the brake motor 3 drives the bidirectional screw 4 to rotate, and the two threaded blocks 5 on the outer side of the bidirectional screw 4 begin to move closer to each other under the limit of the limit rod 6. The two limit rods 6 move closer to each other and drive the two clamping plates 7 to move closer to each other until the two clamping plates 7 clamp and fix the workpiece 8 to be sheeted in the center, which is helpful to clamp and fix workpieces 8 of different sizes to be sheeted, and then the electric push rod 10 can be started, and the electric push rod 10 drives the mounting plate 11 and the mounting box 12 and the punching plate 15 move downward quickly, so that the punching plate 15 punches the workpiece 8 to be punched. When the workpiece 8 to be punched is impacted, the buffer punching plate 15 moves upward slightly, thereby pushing the movable plate 14 to move upward. The movement of the movable plate 14 squeezes and compresses the buffer spring 13, so that the buffer spring 13 reduces the impact force. At the same time, the damper 16 further reduces the impact force. The damper 16 can also prevent the stamping plate 15 from shaking unnecessarily, which helps to reduce the probability of damage caused by excessive impact and improves the safety and stability of punching.
