Technical Field

[0001] The present invention relates to the technical field of cookware processing, and in particular to knurled cookware manufacturing equipment and a processing method. Background Art

[0002] Currently, to increase the heating surface area of ​​metal cookware or improve its appearance, concave and convex patterns are often machined onto the surface of the cookware.

A limit baffle 29 is provided above the output end of the feed conveyor belt 27, and the driving motors of the feed conveyor belt 27 and the discharge conveyor belt 28 are electrically connected to the controller respectively.

[0027] This equipment replaces traditional manual hammering with automated machining, achieving a streamlined process of pot blank forming, pattern pressing, and workpiece transfer. The following is its detailed workflow:

[0028] The feed conveyor 27 delivers the pre-cut, circular metal pot blank to the work area. A stop plate 29 ensures the pot blank stops at the designated position, and the clamping unit uses a rotating suction cup 22 to hold the pot blank in place. The clamping unit moves along the rack track 2, using the electric transfer seat 26 and electric push rod 23 to press the metal pot blank against the top center of the pot mold 7. At this time, the first reduction motor 5 drives the main shaft to rotate. The spinning unit approaches the pot mold 7 along the rack track 2 via the first drive platform 9. The first swing arm 13 adjusts the angle of the spinning roller 14 via the first turntable 12, gradually pressing down from the center of the pot blank toward the edge. Vertical feed is controlled by the first lifting platform 11. Under the action of rotation and pressure, the metal pot blank plastically deforms, conforming to the shape of the pot mold 7 and forming the basic structure of the pot body. After spinning is completed, the clamping unit activates again, transferring the pot body from the pot mold 7 to the knurling die 8. Because the equipment is equipped with dual clamping units, loading and transfer can be performed simultaneously to improve efficiency. After the formed pot body is sent to the knurling die 8, the second reduction motor 6 drives the knurling die 8 to rotate at high speed, and the outer wall of the mold is densely covered with target patterns, such as diamonds, fish scales, etc. The knurling unit approaches the pot body along the rack track 2 through the second drive platform 15. Under the adjustment of the second swing arm 19, the embossing roller 20 squeezes the outer wall of the pot body with constant pressure, forcing the inner wall of the pot body to fit tightly against the knurling die 8. The concave and convex patterns on the surface of the mold are "reversely" copied to the inner wall of the pot body through plastic deformation. After the knurling is completed, the clamping unit absorbs the finished pot and moves it to the discharge conveyor 28. The rotating suction cup 22 releases the pot, and the conveyor transports it out of the work area, completing a processing cycle.

[0029] Compared to traditional manual techniques, this equipment and its accompanying process reduce single-piece processing time from 10 minutes by hand to 1-2 minutes using mechanized methods. The pattern depth and position are precisely controlled by the mold and roller pressure, eliminating the issue of uneven manual pressure. Cookware produced from the same mold has a completely consistent pattern, making it suitable for brand standardization. Through modular design and automated control, this equipment enables the large-scale production of high-quality knurled cookware while balancing cost and aesthetics.
