It involves immersing the cleaned and activated steel products in molten zinc liquid, and coating the steel products with a zinc alloy coating with good adhesion on the surface through the reaction and diffusion between iron and zinc. At present, hot-dip galvanizing of steel is one of the important hot-dip galvanizing products.

[0018] The unpacking robot 210 is a commonly used device in the art. The multi-segment chain bed 230 is a commonly used device in the art.

[0019] A novel method for dismantling a bundle of metal profile steel piles, using the novel dismantling device for dismantling a bundle of metal profile steel piles, comprises the following steps: ① Material preparation and transportation: The steel bundles 110 are placed on the horizontal chain bed 120 and transported forward intermittently; when the steel bundles 110 reach above the swing chain bed 130, the horizontal chain bed 120 stops moving, and the swing chain bed 130 continues to transport the steel bundles 110 backward; when the steel bundles 110 reach directly above the bundle conveying roller 140, the swing chain of the swing chain bed 130 swings downward around the rotating axis to place the steel bundles 110 on the bundle conveying roller 140; the bundle conveying roller is driven by a motor reducer to send the steel bundles 110 to the subsequent unpacking station, and is blocked by a baffle to ensure the accurate stop position; ② Unpacking of steel bundles: The electromagnetic device 211, driven by the unpacking robot 210, extracts the steel bundles 110 in layers, and the single-layer steel bundles 220 separated layer by layer are placed on the multi-segment chain bed 230 of the grouping and spacing equipment for forward transportation; ③ Grouping and spacing: The working process of steel grouping: First, the flip baffle 253 is in a vertical state; the single-layer steel 220 moves forward under the drive of the multi-segment chain bed 230 and is blocked by the flip baffle 253; when the blocked steel reaches the required quantity, the lifting frame 241 rises under the drive of the driving cylinder 242, and lifts up the grouped steel 221 to separate from the multi-segment chain bed 230; then the flip baffle 253 tilts to discharge the material, and the grouped steel group 222 is driven by the multi-segment chain bed 230 to leave the grouping area and be transported to the subsequent process; after the steel group 222 leaves, the flip baffle 253 is erected again, and the lifting frame 241 descends, and the steel group 222 is transported to the subsequent process. The next grouping operation is performed; when the production process adjusts the number of steel sections in the steel section group 222, the flip baffle 253 is adjusted horizontally by a certain distance under the drive of the driving electric cylinder 252 to achieve the requirement of changing the number of steel sections in the steel section group 222; the steel section spacing process is as follows: each top block 264 lifts a steel section in the steel section group 222, and the cam plate 263 moves horizontally on the slide rail 262 under the drive of the driving device, forcing the top block 264 to move along the straight slideway 265 and the radial slideway 266 to achieve the change of the distance between the steel sections, thereby completing the distance change between the steel sections of the steel section group 222, and forming a variable-pitch steel section 223; ④ Loading and transporting of variable pitch steel: the lifting platform 311 drives the sliding sleeve of the car body 312 to move up and down through the pneumatic device 315; the initial position of the loading trolley 310 is below the variable pitch device 260 in the multi-segment chain bed 230. When the variable pitch operation is completed, the lifting platform 311 rises under the action of the pneumatic device 315 to lift the variable pitch steel 223; then, the car body is driven by the driving device and moves along the slide rail 2 314 to the top of the single-layer roller conveyor line 320; the lifting platform 311 descends to place the variable pitch steel 223 on the roller; the single-layer roller conveyor line 320 runs to transport the variable pitch steel 223 to the subsequent process.

[0020] At this point, the dismantling and loading of the entire steel bundle is completed.

[0021] Referring to the accompanying drawings, in the embodiment, a plurality of bundles of steel sections 110 are placed on the horizontal chain bed 120 at a certain interval, and the horizontal chain bed 120, driven by the motor reducer, transports the bundles of steel sections 110 forward. When the front bundle of steel sections arrives at the tail end of the swing chain bed 130, the horizontal chain bed 120 stops transporting, and the swing chain bed 130 runs to transport the bundles of steel sections 110 to the top of the bundle conveying roller 140. Afterwards, the driving motor of the swing chain bed 130 stops running, and the hydraulic device at the bottom of the swing chain bed 130 starts, so that the swing chain bed 130 swings downward, and the bundles of steel sections 110 are placed on the bundle conveying roller 140. The bundle conveying roller 140 is driven by the motor reducer to drive the bundles of steel sections 110 to move forward. When reaching the disassembly position, it is blocked by the baffle 150 and stops, waiting for the unpacking robot 210 to disassemble in layers.

[0022] The front end of the arm of the unpacking robot 210 is equipped with an electromagnetic device 211, which can absorb the steel sections through the electromagnetic force obtained after conducting electricity. Driven by the unpacking robot 210, the electromagnetic device 211 extracts the steel section bundle 110 in layers, and the single-layer steel sections 220 separated layer by layer are placed on the multi-segment chain bed 230 for forward transportation. Figure 5 This is the state where the unpacking robot 210 takes material from the steel bundle 110. Figure 6 In order to meet the requirements of stacking directions of different types of steel sections, the electromagnetic device 211 can also be rotated 180° to achieve the placement of the single-layer steel section 220 in different directions.

[0023] After the unpacking equipment stacks the single-layer steel sections 220 in batches onto the multi-segment chain bed, the multi-segment chain bed 230 drives the single-layer steel sections 220 to be transported forward. Afterwards, it is blocked by the flip baffle of the grouping device to form a tightly arranged state. When the quantity requirement is reached, the jacking device before the grouping device lifts up the remaining steel sections 221 to prevent them from running with the multi-segment chain bed 230. The flip baffle of the grouping device blocks the fall and transports the grouped steel sections 222 to the subsequent stage. In order to meet the requirements of various numbers of groupings, the grouping device can move the distance forward and backward according to the width of the steel section group 222 to meet the requirements of different grouping quantities. The grouped steel section group 222 is in a tightly arranged state and is driven by the multi-segment chain bed 230 to the top of the pitch changing device. The pitch changing device is composed of a cam plate 263 and a top block 264 to form a three-dimensional cam structure. When the cam plate moves, the lifting top block will move accordingly in the radial slide of the cam plate to achieve the effect of pulling the distance between the steel sections apart.

[0024] The loading trolley can move in a straight line, and the lifting platform lifts up the steel section with the pitch changed, and then moves to the top of the single-layer roller conveyor line 320, descends to complete the blanking action, and the single-layer roller conveyor line 320 rotates to transport the steel section to the next process.
