Description

Technical Field

[0001] The invention relates to the technical field of guardrail galvanizing, and in particular to a processing device for guardrail production. Background Art

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metal, alloy or other materials for aesthetics and rust prevention. The main method used is hot-dip galvanizing.

[0003] Zinc is easily soluble in acid and alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will form on the surface of zinc. In sulfur dioxide, hydrogen sulfide and marine atmospheres, zinc has poor corrosion resistance, especially in high temperature, high humidity and organic acid atmospheres, the zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V. For steel substrates, zinc coating is an anodic coating. It is mainly used to prevent corrosion of steel, and its protective performance is closely related to the thickness of the coating. After passivation, dyeing or coating with a light protectant, the protective and decorative properties of the zinc coating can be significantly improved.

[0004] During galvanizing in the prior art, a worker is located on a platform at the edge of the galvanizing pool and uses a sling to place the workpiece into the galvanizing pool. Before placing the workpiece into the galvanizing pool, the zinc slag on the surface of the zinc water is manually driven to one side to prevent the zinc slag from sticking to the surface of the guardrail and affecting the galvanizing quality of the guardrail. After the galvanizing is completed, when the zinc water emerges from the guardrail, the zinc slag on the surface of the zinc water needs to be manually driven to one side to prevent the zinc slag from sticking to the surface of the guardrail. However, the above method is relatively dangerous for employees. Employees operating on the surface of the galvanizing pool are prone to danger, and the high temperature will also cause discomfort to employees. In addition, the efficiency of manually driving away the zinc slag is low, and the zinc slag is constantly being produced. It is difficult to manually drive away the oxide completely, which affects the galvanizing quality of the guardrail. Similarly, the zinc slag will first form a layer of film in the early stage of formation. This film will cause the galvanized layer on the surface of the guardrail to have wrinkles, affecting the appearance. Summary of the invention

[0030] A driving mechanism 7, which is installed on the station switching mechanism 2 and connected to the zinc immersion mechanism 3 and the station switching mechanism 2, and the driving mechanism 7 drives the zinc immersion mechanism 3 and the station switching mechanism 2 to operate respectively; The driving mechanism 7 includes a motor 71 fixed inside one of the mounting frames 24 , and a gear 1 72 is fixed to one end of the output shaft of the motor 71 , one side of the gear 1 72 is meshed with the one-way gear 1 23 , and the other side is meshed with the one-way gear 2 310 .

[0031] A controller is fixed to one side of the mounting frame 24 , and the controller is electrically connected to the motor 71 and the heater respectively.

[0032] Working principle: The galvanizing program is started by the controller, and the controller starts the motor 71 to drive the gear 1 72 to reverse. The reverse rotation of the gear 1 72 satisfies the direction of the one-way gear 2 310 to drive the sleeve 36 to rotate. The rotation of the sleeve 36 drives the shaft 1 34 to rotate through the slider and the slide groove. The rotation of the shaft 1 34 drives the bevel gear 2 35 to rotate. The rotation of the bevel gear 2 35 drives the bevel gear 1 32 to rotate. The rotation of the bevel gear 1 32 drives the reciprocating screw 2 31 to rotate. The rotation of the reciprocating screw 2 31 causes the movable frame 39 to move downward. The downward movement of the movable frame 39 drives the slag prevention mechanism 5 and the slag scraping mechanism 4 to operate and move downward. During the downward movement, the gear 2 412 is always engaged with the gear 3 413. The rotation of the reciprocating screw 2 31 will drive The gear three 413 rotates, the gear three 413 rotates to drive the gear two 412 shaft, the gear two 412 drives the shaft three 411 and the sprocket four 49 to rotate, the sprocket four 49 drives the sprocket three 48 and the shaft two 46 and the bevel gear four 47 to rotate through the chain three 410, the bevel gear four 47 drives the bevel gear three 43 to rotate, the bevel gear three 43 rotates to drive the reciprocating screw three 42 to rotate, the reciprocating screw three 42 rotates to scrape the zinc slag to one side when the bottom of the bottom plate 58 contacts the top of the zinc water, so as to prevent the zinc slag from entering the inside of the slag separation box 51 from the bottom when the box door 56 is opened after the zinc slag follows the slag separation box 51 into the zinc water, and also prevents the zinc slag from sticking to the bottom of the bottom plate 58 and being difficult to unload; When the slag-proof mechanism 5 moves downward, the bottom enters the zinc water and continues to move downward, and then the top plate 55 contacts the top of the C-shaped scraper frame 414, and then the C-shaped scraper frame 414 limits the top plate 55, and continues to move downward, the telescopic rod 54 will squeeze the spring to retract into the telescopic cylinder 53, and at the same time the top plate 55 stops the box door 56 from moving downward, and the box door 56 stops moving downward to cause an opening on one side of the slag-proof box 51, and the clean zinc water in the middle part enters the interior of the slag-proof box through the opening of the slag-proof box 51, and the clean zinc water wraps the guardrail, causing the guardrail to be hot-dip galvanized. When the moving frame 39 moves to the tail of the reciprocating screw rod 231, it resets and drives the slag box 51 to reset upwards. When resetting upwards, the zinc water inside the slag box 51 flows out through the opening, and then the box door 56 is closed again in the zinc water, and then moves upwards to leave the zinc water. The zinc water remaining inside the slag box 51 will flow out through the gap of the box door 56 and the gap of the bottom plate 58. When moving upwards, the C-shaped scraper frame 414 scrapes off the zinc slag on the surface of the slag box 51. When moving upwards, the heater is started to prevent the zinc water on the slag box 51 from solidifying and affecting the opening of the box door 56 and the bottom plate 58. After reset, the controller controls the motor 71 to drive the gear 72 to rotate forward, and the gear 72 rotates forward to meet the direction of the one-way gear 23 driving the reciprocating screw 22 to rotate. The reciprocating screw 22 rotates through the sprocket 25 and the chain 26 to drive another reciprocating screw 22 to rotate. The reciprocating screw 22 rotates to make the moving plate 27 drive the zinc immersion mechanism 3, the slag prevention mechanism 5 and part of the slag scraping mechanism 4 to move away from the top of the galvanizing pool 1, and stop moving after moving to the wire tail. When moving, the rotating shaft 34 is in the sleeve The cylinder 36 slides inside and stops moving, then the motor 71 is started again to drive the gear 1 72 to reverse, so that the slag prevention mechanism 5 moves downward. When moving downward, the L-shaped limit frame 61 limits the top plate 55 to open the box door 56, and then the top rod 63 supports the downward-moving bottom plate 58, so that the bottom plate 58 drives the rotating shaft 4 57 to rotate, and the connecting rod 59 slides inside the arc groove 510, and the bottom plate 58 tilts, so that the internal guardrail slides out, completing the automatic unloading, and the guardrail that needs to be galvanized is manually put back inside for the next round of processing.
