Description
Technical Field
[0001] The present application relates to the technical field of galvanizing process, and in particular to a galvanizing production line for electric power fittings steel caps. Background Art
[0002] In the power fittings industry, steel caps are important components for connecting and fixing equipment, and their anti-corrosion performance directly affects the service life and safety of the equipment; the traditional steel cap galvanizing process mostly uses manual operation, which has problems such as low production efficiency, unstable zinc layer quality control, and serious environmental pollution; with the continuous development of industrial automation technology, the market has put forward higher requirements for the steel cap galvanizing process, that is, it is necessary to achieve efficient, stable and environmentally friendly galvanizing production; therefore, the development of a fully automated power fittings steel cap galvanizing production line has become an inevitable trend in the development of the industry. Summary of the invention
[0003] The problem to be solved by the present application is that the existing manual galvanizing has low output, high labor intensity, and cannot realize unmanned operation and automated batch galvanizing operation with high pass rate.
[0004] In order to solve the above-mentioned technical problems, the present application provides a galvanizing production line for steel caps of electric hardware, including a circular track suspended on the top of a factory building for providing a trajectory for the galvanizing of steel caps, a black piece loading ground rail car for transporting steel caps to be galvanized is arranged at the starting position on the upper part of the track, a white piece unloading ground rail car for transporting galvanized workpieces to a finished product area is arranged at the end position on the upper part of the track, a zinc pot for performing surface galvanizing operations on steel caps is arranged between the black piece loading ground rail car and the white piece unloading ground rail car on the upper part of the track, an electric hoist that moves along its trajectory and can be lifted vertically is arranged on the upper part of the track, and a hanger for hanging multiple steel caps is arranged at the end of the electric hoist.
[0005] Since the assembly line of the present application is designed with a circular track, a black piece loading rail car, a white piece unloading rail car and a zinc pot, the assembly line realizes the full automation of steel cap galvanizing by integrating multiple working procedures such as water washing, plating assistance, drying, galvanizing, zinc control, cooling, and passivation, which not only improves production efficiency and zinc layer quality, but also effectively reduces environmental pollution, meets the market demand for efficient and environmentally friendly galvanizing technology, and solves the problems of low manual galvanizing output, high labor intensity, inability to realize unmanned operation, and automated batch galvanizing operation with a high pass rate.
[0006] Compared with the prior art, the technical solution of this application has the following technical effects: The production line realizes the fully automated operation of steel cap galvanizing. From loading to unloading of finished products, the whole process does not require manual intervention, which greatly improves production efficiency and safety. By setting up two water washing tanks and a plating-assisting tank, the stains on the surface of the steel cap can be effectively cleaned and its surface oxidation can be prevented, making full preparations for the subsequent formation of a dense anti-corrosion layer; The zinc pot uses natural gas as a heat source, which can accurately control the temperature of the zinc liquid and ensure the uniformity and density of the zinc-iron alloy anti-corrosion layer. At the same time, through the instantaneous reciprocating lifting and lowering operation of the electric hoist, the vibration hook can effectively shake off the excess zinc liquid attached to the surface of the steel cap, further controlling the thickness of the zinc layer. Fixed covers are installed above the plating tank and zinc pot to collect and treat the toxic gases and zinc fumes generated during the process, thus reducing environmental pollution. By setting up cooling tanks and passivation tanks, the structural composition and gloss of the galvanized layer surface can be improved, and its wear resistance and service life can be improved.

[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example
[0011] The present application relates to a galvanizing production line for electric power fittings steel caps, such as Figure 1-3As shown, the assembly line includes a circular track 9 suspended on the top of the factory building for providing a galvanizing trajectory for the steel caps 14, and maintenance plank roads are laid on both sides of the track 9. A black piece loading ground rail car 1 for transporting the steel caps 14 to be galvanized is arranged at the starting position on the upper part of the track 9, and a white piece unloading ground rail car 8 for transporting the galvanized workpieces to the finished product area is arranged at the end position on the upper part of the track 9. A zinc pot 5 for performing surface galvanizing operations on the steel caps 14 is arranged between the black piece loading ground rail car 1 and the white piece unloading ground rail car 8 on the upper part of the track 9. The zinc pot 5 uses natural gas as a heat source to melt the metal zinc inside it, and then immerses the steel caps 14 in a zinc solution, so that the zinc solution forms a dense zinc-iron alloy anti-corrosion layer on the surface of the steel caps 14 after cooling. A water washing tank 2, a plating-assisting tank 3 and a drying chamber 4 are arranged in sequence on the upper part of the track 9 between the black piece loading ground rail car 1 and the zinc pot 5. There are two water washing tanks 2, which are used to clean and remove the surface of the steel caps 14. The auxiliary plating tank 3 is used to prevent the surface of the steel cap 14 from being oxidized, so as to prepare for the subsequent formation of a dense anti-corrosion layer. The drying chamber 4 is used to dry the moisture on the outer surface of the steel cap 14. The upper part of the track 9 between the zinc pot 5 and the white piece unloading ground rail car 8 is sequentially arranged with a cooling tank 6 and a passivation tank 7. The cooling tank 6 is used to quickly cool the galvanized steel cap 14 by water bath immersion to avoid the appearance of a gray layer on the coating surface due to a long air cooling time. The passivation tank 7 is used to prevent the workpiece after hot-dip galvanizing from being oxidized during storage and use, so that rust and discoloration appear on the surface of the galvanized layer. At the same time, it also improves the structural composition and gloss of the surface of the galvanized layer, and improves the wear resistance and service life of the galvanized layer. An electric hoist 10 is arranged on the upper part of the track 9, which moves along its track and can be lifted vertically. A hanger 13 for hanging multiple steel caps 14 is arranged at the end of the electric hoist 10, thereby realizing the batch-based fully automatic galvanizing operation of the steel caps 14.
[0012] Among them, the arrangement between the electric hoist 10 and the hanger 13 is as follows: Figure 2As shown, there are two electric hoists 10, which are arranged symmetrically at intervals on the upper part of the track 9. The end of the electric hoist 10 is connected to the hook 12 pulled by the wire rope 11 and the hanger 13, so that the physical height of the hanger 13 is controlled by the retraction and extension of the wire rope 11. When liquid control is required, the electric hoist 10 drives the hanger 13 to perform instantaneous reciprocating lifting and lowering operations, so that the hanger 13 vibrates vertically under the action of gravity, thereby shaking off the excess zinc liquid attached to the surface of the steel cap 14. In order to enhance the vibration effect, the hook 12 and the hanger 13 are connected. A vibration hook can also be added in between. The hanger 13 is composed of a hanging plate 1515, a frame 1616, a partition 1717, and an insertion rod 1818. The frame 1616 is a rectangular parallelepiped structure. The hanging plates 1515 are triangularly spaced and symmetrically arranged on the upper part of the frame 1616. A straight groove for connecting with the hook 12 is formed at the top of the hanging plate 15. Partitions 1717 are evenly and spaced in the length direction of the frame 1616. One side of the partition 1717 is evenly and spaced with vertically arranged insertion rods 1818 for connecting with the steel cap 14.
[0013] The steps of galvanizing the steel cap of electric power fittings 14 are as follows: Step 1: Use the black piece loading ground rail vehicle 1 to hang the steel caps 14 that need to be galvanized on the upper part of the hanger 13 in sequence, and then use the electric hoist 10 to transport the steel caps 14 along the track 9 to the washing tank 2; Step 2: Using the electric hoist 10 to control the hanger 13 to sequentially lift and immerse the two washing tanks 2 for washing; Step 3: The cleaned steel cap 14 is immersed in the auxiliary plating tank 3 for 1 to 3 minutes. The auxiliary plating agent is a mixed aqueous solution of ammonium chloride and zinc chloride. The auxiliary plating agent mainly removes oxides and iron salts on the surface of the steel, thereby ensuring that the surface of the steel remains clean and is not oxidized again before zinc dipping. A fixed cover is installed on the upper part of the auxiliary plating tank 3 to collect the toxic gas generated during the auxiliary plating process, and after harmless treatment, it is discharged into the atmosphere; Step 4: After the plating, the steel cap 14 enters the drying chamber 4 to dry the surface moisture; Step 5: The dried steel cap 14 is immersed in the zinc solution of the zinc pot 5 at an angle of 25-35° for 50-80 seconds to form a zinc-iron alloy anticorrosive layer on its surface, and then taken out from the zinc pot at an angle of 25-35°; Step 6: The galvanized steel cap 14 is suspended for a period of time above the zinc pot 5 to control and remove excess zinc liquid. A fixed cover with top suction and side suction air ports is also arranged above the zinc pot 5 to draw the zinc smoke generated during the galvanizing process into the bag filter for centralized treatment and then discharge; Step 7: The steel cap 14 after zinc control is firstly air-cooled for several seconds, and then after the zinc nodules are removed, it is immediately immersed in the cooling water of the cooling tank 6 for water bath cooling to obtain the steel cap 14 with uniform zinc coating color; Step 8: The galvanized steel cap 14 enters the passivation tank 7 for surface passivation operation, thereby forming a dense anti-oxidation film on the surface of the zinc film; Step nine: Use the white workpiece unloading ground rail car 8 to transport the galvanized workpieces to the finished product area for storage.
