[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0035] Reference Figures 1-8 As shown, a metal product rolling apparatus includes: a base 100, a support 102 fixedly mounted on the base 100, multiple sets of pressure rollers 103 for rolling metal products mounted on the support 102 via a lifting mechanism 200, a cleaning and dust extraction mechanism 300 for cleaning the pressure rollers 103 and the surface of the metal products mounted on the lifting mechanism 200 beside the support 102, and a heating element for heating the metal products during rolling located below the pressure rollers 103 on the base 100; wherein,

[0036] The lifting mechanism 200 includes: a mounting plate 203 that can be lifted and lowered in the vertical direction via a lifting component; multiple sets of parallel pressure rollers 103 are fixedly mounted on the mounting plate 203 via a fixing frame 204; and a cleaning and dust extraction mechanism 300 is provided on the limiting block 206.

[0037] During use, the hardware product is placed below the pressure roller 103 on the base 100, aligned with the pressure roller 103. The heating element is activated to preheat the hardware product to a suitable temperature for calendering, improving the material's ductility. The lifting mechanism 200 drives the mounting plate 203 to descend vertically, bringing the fixing frame 204 and the pressure roller 103 closer to the hardware product. The pressure roller 103 contacts the hardware product and applies pressure. Through the rolling of multiple sets of pressure rollers 103, the hardware product is calendered, changing its thickness or shape. During or before and after calendering, the cleaning and dust extraction mechanism 300 works simultaneously. The cleaning and dust extraction mechanism 300 cleans the surface of the pressure roller 103 and the hardware product, removing impurities, debris, and other contaminants. At the same time, the dust generated during cleaning is removed through the dust extraction function to prevent it from affecting the calendering quality or polluting the working environment.

[0038] Reference Figures 2-6 As shown, the lifting component includes: an electric telescopic rod 201, a limiting rod 202, and a limiting block 206; wherein,

[0039] An electric telescopic rod 201 is fixedly mounted on the bracket 102. The output end of the electric telescopic rod 201 is vertically downward and the top end is fixedly mounted with an mounting plate 203. A limit rod 202 slides vertically through the bracket 102. The mounting plate 203 is fixedly connected to the bottom surface of the limit rod 202. A vertically arranged limit groove 205 is opened on the side wall of the bracket 102 that is far apart from each other. A limit block 206 that slides with the limit groove 205 is fixedly mounted on the side of the mounting plate 203.

[0040] In the above scheme, when it is necessary to adjust the height of the pressure roller 103, the output end of the electric telescopic rod 201 moves vertically downward or upward, driving the mounting plate 203 fixedly connected to it to rise and fall synchronously. During the rising and falling of the mounting plate 203, the limiting rod 202 slides synchronously in the vertical sliding hole of the bracket 102 to ensure that the mounting plate 203 moves smoothly in the vertical direction and prevents deviation or shaking. The limiting block 206 on the side of the mounting plate 203 slides in the limiting groove 205 of the bracket 102 to further constrain the movement trajectory of the mounting plate 203 and ensure the stability and accuracy of the rising and falling of the pressure roller 103.

[0041] Reference Figures 5-6 As shown, the cleaning and vacuuming mechanism 300 includes: a vacuum chamber 302, a cleaning plate 305, and a vacuum cleaner 307; wherein,

[0042] Two sets of dust collection chambers 302 are fixedly connected to the front and rear sides of the mounting plate 203 via connecting brackets 301. Each set of dust collection chambers 302 has a cleaning plate 305 for cleaning on the side that contacts the pressure roller 103, and a second dust collection port 306 is opened on this side. A vacuum cleaner 307 corresponding to each dust collection chamber 302 is fixedly installed on the mounting plate 203. The output end of the vacuum cleaner 307 is connected to the dust collection chamber 302 via a connecting pipe 308.

[0043] In the above scheme, before or during the calendering operation, the vacuum cleaner 307 is started, and a negative pressure is formed in the vacuum chamber 302 through the connecting pipe 308. The vacuum chamber 302 is fixed to the mounting plate 203 through the connecting frame 301. When the pressure roller 103 is raised and lowered, the vacuum chamber 302 moves synchronously, so that the cleaning plate 305 always keeps in contact with the surface of the pressure roller 103. The cleaning plate 305 scrapes off metal debris, oxide scale and other impurities from the surface of the pressure roller 103. While the cleaning plate 305 is working, the impurities are sucked into the vacuum chamber 302 and enter the dust collection device of the vacuum cleaner 307 through the connecting pipe 308.

[0044] Reference Figures 5-6 As shown, the cleaning and vacuuming mechanism 300 further includes a cleaning head 303. The bottom surface of the vacuum chamber 302 is provided with a first vacuum port 304 above the hardware product. The cleaning head 303, which is in contact with the surface of the hardware product, is fixedly provided on the vacuum chamber 302 around the first vacuum port 304.

[0045] In the above scheme, when the pressure roller 103 adjusts its height through the lifting mechanism 200, the dust collection chamber 302 descends synchronously with the mounting plate 203, so that the cleaning head 303 contacts the surface of the hardware product. The cleaning head 303 moves on the surface of the hardware product, loosening and peeling off impurities such as oxide layer, oil stains or debris. The negative pressure generated by the vacuum cleaner 307 directly sucks the impurities loosened by the cleaning head 303 into the dust collection chamber 302 through the first dust suction port 304, while adsorbing the new debris generated during the calendering process.

[0046] Reference Figure 1 and Figure 4 As shown, the heating element includes a heating plate 101 and a heating tube 104; the heating tube 104 is fixedly disposed in the base 100 below the pressure roller 103, and a heating plate 101 for placing hardware products is fixedly disposed on the base 100 above the heating tube 104 and in contact with the heating tube 104.

[0047] In the above scheme, before the calendering operation, the heating tube 104 is energized and heated. The heat of the heating tube 104 is evenly transferred to the heating plate 101 through heat conduction, which improves the ductility of the material and can achieve a thinner calendering thickness.

[0048] Reference Figures 7-8As shown, the rolling apparatus further includes an anti-deviation mechanism 400 for limiting the rolling of metal products. The anti-deviation mechanism 400 includes: a driving component, a limiting plate 404, and a sliding rod 407; wherein,

[0049] The base 100 has multiple sets of parallel sliding grooves 401. Two sets of opposing limiting plates 404 with adjustable spacing are slidably arranged in the sliding grooves 401 via a driving component. Sliding rods 407 are fixedly provided on both sets of limiting plates 404. Rotating rollers 408 are slidably sleeved on the sliding rods 407. Fixing blocks 409 are fixedly provided at one end of each of the two sets of sliding rods 407 to prevent the rotating rollers 408 from falling off.

[0050] A gear 405 is rotatably mounted inside the base 100. A drive motor 406 is fixedly mounted inside the base 100. The output shaft of the drive motor 406 is vertically downward and its top end is fixedly connected to the gear 405. Two sets of racks 402 are slidably mounted on both sides of the gear 405 inside the base 100, and both sets of racks 402 are meshed with the gear 405. Limiting plates 404 are fixedly connected to the two sets of racks 402 through sliders 403, and the sliders 403 are slidably engaged with the inner sidewall of the groove 401.

[0051] In use, the drive motor 406 drives the gear 405 to rotate, which in turn drives the two sets of racks 402 meshing with it to move in opposite directions. The distance between the two limiting plates 404 is adjusted synchronously by the slider 403 to accommodate hardware products of different widths. When the hardware product passes through the pressure roller 103, the rotating rollers 408 on the two limiting plates 404 contact the edge of the product. The rotating rollers 408 can roll freely on the slide bar 407, which not only limits the lateral displacement of the product but also reduces the frictional resistance with the product. The fixing block 409 restricts the axial displacement of the rotating rollers 408 to ensure that they always remain in the effective constraint position.

[0052] In summary, the hardware product rolling device provided by this utility model allows the operator to place the hardware product to be processed on the heating plate 101, aligning its front end with the inlet position of the pressure roller 103, with the two side edges of the product slightly contacting the rotating roller 408 to ensure automatic centering. The heating plate 101 continuously supplies heat, allowing the product to reach the process temperature within 2-3 minutes, reducing the material's resistance to deformation. The electric telescopic rod 201 drives the mounting plate 203 to descend, bringing the pressure roller 103 into contact with the hardware product. The limiting rod 202 and the limiting block 20... 6. Ensure that the pressure roller 103 descends vertically. Multiple sets of pressure rollers 103 apply pressure step by step to achieve uniform deformation. The cleaning plate 305 scrapes off metal debris from the surface of the pressure roller 103. The second dust suction port 306 sucks impurities into the dust suction chamber 302. The cleaning head 303 cleans the upper surface of the product. The first dust suction port 304 simultaneously absorbs dust. During the rolling process, the limiting plate 404 applies lateral constraints to both sides of the product through the rotating roller 408 to limit lateral displacement. The rotating roller 408 rolls freely on the slide bar 407 to reduce frictional resistance and avoid scratching the edges of the product.
