Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanized sheet technology, specifically to a device for optimizing the surface roughness of hot-dip galvanized sheets. Background Technology

[0002] Hot-dip galvanized steel sheet is a material formed by combining steel and zinc. It is produced by immersing treated steel strips directly into molten zinc. This method gives hot-dip galvanized steel sheet the strength and plasticity of steel, while also providing a corrosion-resistant coating. It is widely used in construction, home appliances, automobiles and other fields.

[0003] During the processing of hot-dip galvanized sheets, factors such as fluctuations in the composition of the zinc bath, insufficient pretreatment of the substrate, and unreasonable cooling methods can easily lead to excessive surface roughness. Therefore, after completing the above processing operations, it is necessary to optimize the surface roughness of the hot-dip galvanized sheets. Currently, most roughness optimization operations are carried out by personnel using handheld grinding devices. However, during the grinding process, waste chips are easily scattered. If workers accidentally inhale them, it will seriously affect their health.

[0004] At the same time, the above-mentioned grinding methods are not easy to control the grinding depth, which can easily damage the zinc layer and affect the overall performance of the hot-dip galvanized sheet. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] Please see Figure 1-4 A device for optimizing the surface roughness of hot-dip galvanized steel sheets includes a frame 1, which is a table-shaped frame. A pair of first lead screw modules 2 are symmetrically arranged on the lower side of the tabletop of the frame 1, extending along the length of the tabletop and positioned near the edge of the lower side. A movable frame 3, which is a portal frame, is positioned above the frame 1. The two legs of the movable frame 3 are located on the left and right sides of the tabletop, respectively. The lower sides of the two legs extend to the lower side of the tabletop and are slidably connected to the pair of first lead screw modules 2. Vertically extending guide grooves are provided on both legs of the movable frame 3. A lifting seat 4 is provided between the two legs of the movable frame 3. Vertically extending second lead screw modules 5 are provided on the outer sides of both legs of the movable frame 3. The lifting seat 4 passes through the guide grooves at both ends and is slidably connected to the second lead screw modules 5.

[0023] A dust collection box 6 is provided on the upper side of the lifting seat 4, a grinding roller 7 is provided on the lower side of the lifting seat 4, and dust collection covers 8 are provided on both the front and rear sides of the grinding roller 7. The front and rear sides of the dust collection box 6 are connected to the dust collection covers 8 through pipes 13. A fan 9 is provided on the upper side of the dust collection box 6, and a fixing component is provided on the upper side of the frame 1.

[0024] The fixed assembly includes a vacuum pump 10 mounted on the upper side of the frame 1. Fixing frames 11 are provided on both the left and right sides of the upper side of the frame 1, as shown in the figure. The fixing frames 11 are plate-shaped and hollow inside. A vacuum suction cup 12 is provided on the upper side of the fixing frames 11. The fixing frames 11 are connected to the vacuum pump 10 through a pipe 13.

[0025] During use, the operator can place the hot-dip galvanized sheet on the upper side of the fixing frame 11, and then control the vacuum pump 10 to run. With the help of the vacuum suction cups 12, the bottom four corners of the hot-dip galvanized sheet can be fixed. At the same time, the four vacuum suction cups 12 are of the same specification, which can maintain the horizontal flatness of the hot-dip galvanized sheet while fixing it.

[0026] Subsequently, the first lead screw module 2 is controlled to operate synchronously, driving the moving frame 3 and the components located on the upper side of the moving frame 3 to move. At the same time, the second lead screw module 5 is controlled to operate synchronously, which can drive the lifting seat 4 to descend. The lifting seat 4 is equipped with a distance sensor 16 on its lower side, which is used to measure the distance between the grinding roller 7 and the zinc plate, thereby facilitating precise control of the grinding depth and ensuring the optimization of the surface roughness of the hot-dip galvanized sheet.

[0027] During the polishing process, the fan 9 operates, drawing air from the dust collection box 6 to create negative pressure inside. The dust collection box 6 then collects the polishing debris generated during the polishing process through the pipe 13 and the dust collection hood 8. The dust collection box 6 is equipped with a dust collection bag, which is connected to the pipe 13. This filter removes debris and other impurities, preventing them from entering the fan 9. This technology is existing and will not be described in detail.

[0028] The ranging sensor 16 can be a Leuze ranging sensor 160DSL 96B M / C6-S12, which has high precision characteristics and is convenient for detecting the grinding depth of zinc plate. Then, in conjunction with the high-precision second lead screw module 5, it can realize high-precision surface roughness optimization operation of hot-dip galvanized plate. At the same time, each independent lead screw module in the pair of first lead screw modules 2 and the pair of second lead screw modules 5 is equipped with an independent driver. Through the synchronous control algorithm, the synchronous operation of different drivers is realized, thereby enabling the pair of first lead screw modules 2 and the pair of second lead screw modules 5 to operate synchronously and accurately.

[0029] The lower side of the mobile frame 3 is provided with reinforcing ribs 14. Specifically, the lower part of the mobile frame 3 extending under the tabletop is provided with reinforcing ribs 14 between the support legs to increase the overall strength of the mobile frame 3.

[0030] The inner side of the movable frame 3 is provided with a guide rod 15, and the two sides of the lifting seat 4 are slidably connected to the guide rod 15 to increase the stability of the lifting seat 4 during the lifting process.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
