[0002] Precision metal parts include precision plastic metal parts, precision stamping metal parts, precision turning metal parts, etc., which are widely used in the manufacture of precision equipment in the electronics, clocks, aviation, chemical, agriculture, medicine and other industries. A precision metal parts continuous stamping forming control device is disclosed in the Chinese utility model patent with the announcement number CN220277991U. The precision metal parts continuous stamping forming control device can easily replace the stamping seat and the storage seat, so that the device can be used for stamping work of different precision metal parts, increasing its scope of application.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: In the above-mentioned structure, when replacing the stamping seat and the storage seat, it is necessary to remove the bolts on the stamping seat and the storage seat, take the stamping seat out of the installation slot, and take the storage seat out of the top slot, and then the stamping seat and the storage seat can be replaced. Generally speaking, the lower stamping seat and the storage seat are heavier. When installing the lower stamping seat, it is necessary to lift it up and align it in the installation slot. Its installation is more difficult, and different lower stamping seats have different sizes. The overall situation of the installation slot remains unchanged, and the lower stamping seat needs to be customized to match the installation slot, which increases the cost. To this end, we designed a high-hardness metal parts precision forming device. Utility Model Content

[0023] An installation groove is opened in the middle of the upper surface of the installation base 1, and the installation base plate 2 is placed in the installation groove and fixed by countersunk screws. The installation base 1 can be removed as needed, so as to facilitate the opening of a mounting screw hole 21 on its upper surface that matches the new stamping die. In subsequent work, it is suitable for the installation of stamping dies of various sizes and models.

[0024] A plurality of mounting screw holes 21 are provided on the upper surface of the mounting base 1, and the positions and number of the mounting screw holes 21 correspond to the positions and number of the screw holes of the lower die base 3, and the two are fixed by countersunk screws. A plurality of mounting screw holes 61 are provided on the upper surface of the upper mounting plate 6, and the positions and number of the mounting screw holes 61 correspond to the positions and number of the screw holes of the upper die base 31, and the two are fixed by countersunk screws. The mounting base 1 and the upper mounting plate 6 can both be provided with mounting screw holes 21 and mounting screw holes 61 that match the new stamping die, which are suitable for the installation of stamping dies of various sizes and models in subsequent work, and can ensure the accuracy of the upper and lower positioning of the stamping die, so that the formed metal parts have higher precision.

[0025] The upper and lower surfaces of the mounting slide 5 are penetrated with mounting notches 51, and the length and width of the mounting notches 51 are smaller than the length and width of the upper mounting plate 6. The upper mounting plate 6 can be quickly mounted on the mounting slide 5 by screws, and is easy to disassemble, and is convenient for opening in subsequent operations. The second mounting screw hole 61 matches the new stamping die.

[0026] Slide holes are provided at the four corners of the installation slide 5. The installation slide 5 passes through the support column 4 through the slide holes and slides up and down. The support column 4 can guide it, making its operation more stable and improving the processing accuracy.

[0027] A through hole is provided at the center of the upper surface of the mounting top plate 7, and the hydraulic cylinder 29 is installed above the mounting top plate 7, and the push rod of the hydraulic cylinder 29 passes through the through hole and is placed below the mounting top plate 7. A contact circular plate 91 is installed at the bottom end of the push rod of the hydraulic cylinder 29, and the contact circular plate 91 is in contact with the upper surface of the upper mounting plate 6 but not connected. The hydraulic cylinder 29 can apply a force to the center of the upper mounting plate 6, so that the overall force is more uniform, so that the upper mold base 31 can better process and shape the metal parts below.

[0028] The implementation principle of a high-hardness metal part precision forming device in the embodiment of the present application is as follows: when stamping, the metal part is placed above the lower die seat 3, and the push rods of the two hydraulic cylinders 1 8 and the hydraulic cylinder 2 9 will move downward synchronously, thereby causing the upper die seat 31 to move downward and stamp the metal part below;

[0029] When it is necessary to replace the upper die base 31 and the lower die base 3, first move the upper die base 31 downward and place it in the lower die base 3. At this time, the countersunk screws between the upper die base 31 and the upper mounting plate 6 can be removed, and the countersunk screws between the lower die base 3 and the mounting base plate 2 can be removed. At this time, the upper die base 31 and the lower die base 3 are respectively disconnected from the upper mounting plate 6 and the mounting base plate 2, and the mounting slide 5 and the upper mounting plate 6 are moved up as a whole, and the upper die base 31 and the lower die base 3 can be removed, and then the new upper die base 31 is closed above the upper die base 31, and the lower die base 3 is placed on the mounting base plate 2, and the position and number of the mounting screw holes 21 between them correspond to the position and number of the screw holes of the lower die base 3, and they are fixed by countersunk screws, and then the mounting slide 5 and the upper mounting plate 6 are moved downward as a whole, and the upper die base 31 and the upper mounting plate 6 are fixed by countersunk screws;

[0030] When the replaced upper die seat 31 and lower die seat 3 are new die, the push rod of the hydraulic cylinder 2 9 can be moved up independently after the upper die seat 31 and lower die seat 3 are removed by the above operation, and then the screws between the upper mounting plate 6 and the mounting slide 5 are removed, and the upper mounting plate 6 is removed, and the mounting base plate 2 can also be taken out from the mounting base 1, and the mounting screw hole 1 21 and the mounting screw hole 2 61 matching the new stamping die are opened on the mounting base plate 2 and the upper mounting plate 6;

[0031] By installing the upper die base 31 and the lower die base 3 on the upper mounting plate 6 and the mounting bottom plate 2 respectively, and the upper die base 31 can be placed on the upper part of the lower die base 3 before installation or removal, workers do not need to lift the upper die base 31 during installation or removal, which improves convenience. The upper die base 31 and the lower die base 3 are placed together before installation, so that the upper die base 31 can be placed directly above the lower die base 3, which can ensure the accuracy during stamping and make the formed metal parts more accurate.

[0032] The mounting base 1 and the upper mounting plate 6 can be quickly disassembled, so that mounting screw hole 1 21 and mounting screw hole 2 61 matching the new stamping die can be opened on the mounting base 1 and the upper mounting plate 6. In subsequent work, it is suitable for the installation of stamping dies of various sizes and models, and can ensure the accuracy of the upper and lower positioning of the stamping die, so that the formed metal parts have higher precision.
