[0023] Example 1

[0024] like Figures 1-5 As shown;

[0025] A stamping device for processing hardware products includes a base 1, a mold frame 2 fixed above the base 1, an installation groove 3 opened in the upper part of the mold frame 2, a lower mold 4 placed inside the installation groove 3, support base plates 8 on both sides below the lower mold 4, and a hydraulic push rod 9 fixedly connected to the lower part of the support base plate 8; an upper mold 10 is provided above the mold frame 2, an installation plate 15 is fixed above the upper mold 10, a lifting plate 11 is provided above the installation plate 15, and a lifting hydraulic cylinder 12 is connected to the upper part of the lifting plate 11.

[0026] In this implementation scheme: the lower mold 4 is installed through the mounting groove 3, and only the lower mold 4 of different sizes needs to be replaced to adapt to different workpiece requirements. At the same time, the positioning block 13 and the positioning pin 14 facilitate the connection between the upper mold 10 and the lifting plate 11, making it easy to quickly disassemble and assemble the mold, significantly shortening the mold change time and improving production flexibility.

[0027] Furthermore:

[0028] In an optional embodiment, the lower mold 4 is sized to match the mounting groove 3, and the lower mold 4 is detachably connected to the mold frame 2.

[0029] In this implementation scheme: the lower mold 4 is connected to the mounting groove 3, and only the lower mold 4 of different sizes needs to be replaced to adapt to different workpiece requirements.

[0030] Furthermore:

[0031] In an optional embodiment, the support base plate 8 is symmetrically distributed about the vertical center line of the mold frame 2, and the hydraulic push rod 9 forms a telescopic structure with the support base plate 8.

[0032] In this implementation scheme: the symmetrically distributed support base plate 8 can be adjusted in height by hydraulic push rod 9, which can dynamically balance the force on the lower mold 4, prevent mold displacement or workpiece deformation due to uneven force during the stamping process, and improve the quality of stamped finished products.

[0033] Furthermore:

[0034] In an optional embodiment, positioning blocks 13 are engaged on both sides of the mounting plate 15 and the lifting plate 11, and positioning pins 14 are inserted inside the positioning blocks 13.

[0035] In this implementation scheme: the positioning block 13 and the positioning pin 14 facilitate the connection between the upper mold 10 and the lifting plate 11, make the mold quick to disassemble and assemble, significantly shorten the mold change time, and improve production flexibility.

[0036] Furthermore:

[0037] In an optional embodiment, the upper mold 10 is connected to the lifting plate 11 via the mounting plate 15, and the lifting hydraulic cylinder 12 forms a telescopic structure between the lifting plate 11 and the upper mold 10.

[0038] In this implementation scheme: the lifting hydraulic cylinder 12 can drive the lifting plate 11 and the mounting plate 15 to move vertically, ensuring vertical pressure on the upper mold 10.

[0039] Furthermore:

[0040] In an optional embodiment, a reserved groove 5 is provided at the center of the bottom of the lower mold 4, a lifting top plate 6 is provided on the inner side of the reserved groove 5, and a lifting push rod 7 is fixed below the lifting top plate 6.

[0041] In this implementation plan: the lifting push rod 7 drives the lifting top plate 6 to push the workpiece out of the lower mold 4, realizing automated material discharge, reducing manual intervention and improving production efficiency.

[0042] Furthermore:

[0043] In an optional embodiment, collection boxes 16 are installed on both sides outside the frame 2.

[0044] In this implementation plan: the collection box 16 facilitates manual collection of debris and waste generated during the stamping process, keeping the work area clean.

[0045] Working principle: First, select and install the appropriate upper and lower molds as needed. Install the upper mold 10 below the lifting plate 11, aligning the mounting plate 15 with the lifting plate 11. Then, secure the positioning block 13 to the outside of the mounting plate 15 and the lifting plate 11, and insert the positioning pin 14 into the positioning block 13 to fix the upper mold 10. Next, install the lower mold 4. Select the matching lower mold 4 and place it in the mounting groove 3. The outer ring and the reserved groove 5 at the bottom of each size of the lower mold 4 are the same, only the inner ring is different, thus achieving matching between different molds and the mounting groove 3. Then, activate the hydraulic push rod 9, which drives the support base plate 8 to rise and fall to the lower end of the lower mold 4, keeping the upper end of the lower mold 4 level with the mold frame 2. At this time, the lifting top plate 6 is in the lower mold position. The upper mold 10 is positioned at the reserved groove 5 at the bottom of mold 4 and adjusted so that the upper end of the lifting top plate 6 is flush with the inner bottom surface of the lower mold 4. Then, the metal workpiece is placed on the lower mold 4, and the lifting hydraulic cylinder 12 is activated. The lifting hydraulic cylinder 12 drives the lifting plate 11 to move vertically, causing the upper mold 10 to press downward. The upper mold 10 is embedded in the lower mold 4, thus completing the workpiece stamping. During this process, the supporting base plates 8 distributed symmetrically on both sides can provide stable support for the lower mold 4. Finally, after the stamping is completed, the upper mold 10 returns to its original position, and the lifting push rod 7 is activated. The lifting push rod 7 drives the lifting top plate 6 in the reserved groove 5 to rise, pushing the stamped workpiece out from the surface of the lower mold 4, which facilitates material discharge. At the same time, during the processing, debris on the mold frame 2 can be cleaned to both sides and fall into the collection box 16, which helps to keep the work station clean.

[0046] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
