[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 A metal stamping machine for a keyboard frame includes a lower die assembly 1, a stamping assembly 2, a base plate 3, and a control panel. The lower die assembly 1 includes a connecting plate 101. The top of the connecting plate 101 is provided with an opening. A supporting mold 102 is provided in the opening. Connecting seats 103 are fixed to the outer walls of the supporting mold 102 on multiple sides by bolts. The connecting seats 103 are fixed to the connecting plate 101 by bolts.

[0026] The stamping assembly 2 includes a fixed shell 201, a fixed plate 202 welded between the inner walls of the fixed shell 201, a first hydraulic cylinder 203 fixed to the top of the fixed plate 202 by bolts, a sliding plate 204 fixed to the bottom of the first hydraulic cylinder 203 by bolts, and a stamping block 205 fixed to the bottom of the sliding plate 204 by bolts. The gap between the stamping block 205 and the supporting mold 102 is 0.1mm, and an H7 / g6 tolerance fit is adopted to ensure that there are no burrs on the stamping edge. The stamping block 205 protrudes from the bottom of the fixed shell 201. Under the drive of the first hydraulic cylinder 203, the sliding plate 204 moves downward, thereby driving the stamping block 205 to move downward, and thus stamping the metal blank shell.

[0027] The bottom of the fixed shell 201 is fixed with a limit frame 206 by bolts. The top of the base plate 3 is welded with a frame 4. The top outer wall of the frame 4 is fixed with a second hydraulic cylinder 5 by bolts. The bottom end of the second hydraulic cylinder 5 is fixedly connected to the top outer wall of the fixed shell 201. Under the drive of the second hydraulic cylinder 5, the stamping assembly 2 moves downward, so that the limit frame 206 presses on the metal blank shell, thereby pressing the metal blank shell tightly.

[0028] Waste collection box 6 and finished product collection box 10 are placed on the top of the base plate 3. The finished product falls into the finished product collection box 10 under the action of gravity and is collected. Waste collection box 6 is located below the opening of the lower mold assembly 1.

[0029] Two support blocks 7 are welded to the top of the base plate 3, and the connecting plate 101 is placed on top of the two support blocks 7, thereby supporting the lower mold assembly 1 through the support blocks 7.

[0030] A fixing block 8 is welded to the top of the base plate 3. A support seat is fixed to one side of the fixing block 8 by bolts. A drive motor 9 is fixed to the top of the support seat by bolts. The drive motor 9 is a servo motor. A rotating shaft is keyed to the output end of the drive motor 9. One side of the connecting plate 101 is fixedly connected to the outer wall of the rotating shaft. A rotating seat is welded to the top of the fixing block 8. The rotating shaft and the rotating seat are rotatably connected by an embedded bearing. Under the drive of the drive motor 9, the rotating shaft rotates, thereby causing the connecting plate 101 to flip, so that the lower mold assembly 1 is upside down on top of the finished product collection box 10 for the finished product to be unloaded.

[0031] A bearing block 11 is welded to the top of the base plate 3. The finished product collection box 10 is located between the fixed block 8 and the bearing block 11. A vibration motor 12 is fixed to one side of the bearing block 11 by bolts. The model of the vibration motor 12 can be MVE200 / 3, with a vibration frequency of 50Hz. The finished product is evenly dispersed in the collection box by the vibration of the eccentric block. The vibration motor 12 drives the finished product collection box 10 to vibrate so that the finished product falls to the bottom of the finished product collection box 10.

[0032] The control panel is connected to the first hydraulic cylinder 203, the second hydraulic cylinder 5, the drive motor 9, and the vibration motor 12 via wires.

[0033] The working principle of this embodiment is as follows: In use, firstly, the metal blank is inverted and placed on the top of the support mold 102. Then, the second hydraulic cylinder 5 is started. Under the drive of the second hydraulic cylinder 5, the stamping component 2 moves downward, so that the limiting frame 206 presses on the metal blank, thereby pressing the metal blank tightly. Next, the first hydraulic cylinder 203 is started. Under the drive of the first hydraulic cylinder 203, the sliding plate 204 moves downward, thereby driving the stamping block 205 to move downward, thereby stamping the metal blank. The metal fragments generated by stamping fall into the waste collection box 6 for collection.

[0034] After stamping is completed, the stamping assembly 2 is retracted by the first hydraulic cylinder 203 and the second hydraulic cylinder 5. Then, the drive motor 9 is started, and the rotating shaft rotates under the drive of the drive motor 9, thereby causing the connecting plate 101 to flip over, so that the lower die assembly 1 is upside down on the finished product collection box 10. Then, the finished product falls into the finished product collection box 10 for collection under the action of gravity, and the vibration motor 12 drives the finished product collection box 10 to vibrate so that the finished product falls to the bottom of the finished product collection box 10.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
