Description

Technical Field

[0001] The invention relates to the field of metal processing, and more particularly to a hardware surface processing device. Background Art

[0002] There are many ways to treat metal surfaces. According to their characteristics, they can be divided into three categories: solvent cleaning, mechanical treatment and chemical treatment. They can be further divided into: electroplating, electrophoresis, anodizing, passivation, phosphating, polishing and etching. In order to make hardware beautiful and rust-proof, a layer of zinc is plated on the surface of the hardware. The galvanizing process mainly includes hot-dip galvanizing and cold-dip galvanizing. Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing. It is to immerse the rust-removed steel parts in molten zinc liquid at about 500°C to make a zinc layer adhere to the surface of the steel components, thereby achieving the purpose of corrosion protection. It is an effective way to prevent metal corrosion.

[0003] A Chinese patent with authorization announcement number CN115874131B discloses a hot-dip galvanizing device, which drives the first threaded rod to rotate by rotating the motor output shaft, thereby driving the filter plate to move up, and the filter plate moves above the zinc liquid. The zinc liquid flows back into the storage tank from the drainage hole, and iron slag remains on the filter plate. The cleaning component then cleans the iron slag on the filter plate. It is relatively convenient to remove the iron slag in the machine body, which is beneficial to ensuring the galvanizing effect of steel products.

[0004] The Chinese patent with authorization announcement number CN115466917B discloses a hot-dip galvanizing equipment, which helps to reduce the number of people required to install the metal support rod on the hanger through a loading platform, a hot-dip galvanizing pool, a spin drying drum, a cooling pool, a feeding device, a first lifting device, a second lifting device, a rod insertion device and a rod extraction device.

[0005] The first method mentioned above cleans the iron slag on the filter plate through a cleaning component, and the second method helps to reduce the manpower required to install the metal support rod on the hanger through a pull-out rod device. However, neither of them solves the problem that during the galvanizing process, impurities from the outside world and the surface of the hardware float on the surface of liquid zinc, causing some impurities to exist on the galvanized surface of the hardware, resulting in a decrease in the anti-corrosion and other performance effects of the hardware. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a hardware surface treatment device, in which a scraper moves impurities on the surface of molten zinc in the galvanizing pool to both sides of the galvanizing pool to prevent impurities on the surface of the zinc from adhering to the surface of the hardware when the hardware enters the zinc in the galvanizing pool, causing impurities in the plating layer on the surface of the hardware, resulting in poor corrosion protection and other beneficial effects of the hardware.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0009] Furthermore, a driving member is arranged between the lower pressure plate and the guide plate, and the driving member includes a connecting rod rotatably connected to the top of the lower pressure plate, and a slider is rotatably connected to the bottom of the connecting rod. A first sliding groove is opened at the top of the galvanizing pool corresponding to the lateral movement trajectory of the slider, and the rear side of the slider is connected to the guide plate.

[0010] Furthermore, a first spring fixedly connected to the sliding block is arranged inside the first sliding groove, and when the guide plate blocks the top of the galvanizing pool, the first spring is in a naturally extended state.

[0011] Furthermore, a first guide groove is provided on a side of the guide plate close to the scraper, and the height of the guide plate gradually decreases from the side close to the connecting rod to the side away from the connecting rod.

[0012] Furthermore, the distance between the front and rear sides of the first guide groove is the same as the internal width of the guide plate, and a plurality of second guide grooves extend downward from the side of the first guide groove away from the scraper plate, and a circular hole penetrating the guide plate is formed at one end of the plurality of second guide grooves away from the first guide groove.

[0013] Furthermore, the rear side of the slider is connected to the guide plate, and a first spring fixedly connected to the slider is arranged inside the first sliding groove.

[0014] Furthermore, both front and rear sides of the bottom of the guide plate extend downward to form a first extrusion block, and the inner wall of the galvanizing pool is provided with a stirring member, and the stirring member includes a rotating rod rotatably connected to the galvanizing pool, and the top of the rotating rod is rotatably connected to the galvanizing pool through a reset mechanism combined with a torsion spring and a rotating shaft, and a first longitudinal groove for accommodating the rotation of the rotating rod is provided inside the galvanizing pool corresponding to the rotation position of the rotating rod, and a connecting block is fixedly connected to the top of the rotating rod.

[0015] Furthermore, the connecting block and the first extrusion block are in the same horizontal plane, a second transverse groove is provided inside the galvanizing pool at a position corresponding to the connecting block, a stirring rod is fixedly connected to the bottom of the rotating rod, and a first transverse groove is provided inside the galvanizing pool at a position corresponding to the stirring rod.

[0016] Furthermore, a first extension block is fixedly connected inside the scraper, a limiting groove for accommodating the movement of the first extension block is provided inside the limiting plate at a position corresponding to the first extension block, a cavity is provided inside the scraper, and the scraper is made of aluminum.

[0017] Furthermore, the scraper is rotatably connected to a flip plate on one side close to the galvanizing pool, the flip plate is fixedly connected to a second extrusion block on one side away from the limit plate, the bottom of the cavity is slidably connected to a collecting plate, an extension groove is provided on the rear side of the galvanizing pool, a second slide groove is provided inside the scraper corresponding to the moving track of the second extension block, a second spring is provided on the front side of the collecting plate, and the second spring is in a taut state when the collecting plate is inside the galvanizing pool.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This scheme opens a hook hole on the surface of the lower pressure plate, so that the hardware connected to the hook can be hung under the lower pressure plate by using the hook hole, so that the lower pressure plate can move with the hardware to the inside of the galvanizing pool during the pressing process, so that the hardware can enter the molten zinc and the surface of the hardware can be galvanized. The movement of the limit plate can move the scraper, so that the scraper moves horizontally in the galvanizing pool, so that the scraper can move the impurities on the surface of the molten zinc in the galvanizing pool to both sides of the galvanizing pool, so as to prevent the impurities on the surface of the zinc from adhering to the surface of the hardware when the hardware enters the zinc in the galvanizing pool, resulting in impurities in the plating layer on the surface of the hardware, resulting in poor corrosion protection and other beneficial effects of the hardware.

[0019] 2. In this solution, when the lower pressure plate is not moving downward, the guide plate blocks the opening at the top of the galvanizing pool to prevent heat loss inside the galvanizing pool. When the hardware is hung at the bottom of the lower pressure plate, when the hardware falls, the hardware falls on the surface of the guide plate to prevent the molten zinc inside the galvanizing pool from splashing out when the hardware falls into the galvanizing pool, causing injuries to the staff, making it safer for the staff to hang the hardware.

[0020] 3. In this solution, when the hardware leaves the galvanizing pool and moves upward to its original position, the guide plate returns to its original position under the action of the driving member, and the guide plate blocks the top of the galvanizing pool, while the molten zinc on the surface of the hardware drips downward, the molten zinc drips inside the guide plate, and the zinc reaches the inside of the galvanizing pool along the second guide groove, which is convenient for recycling excess zinc on the surface of the hardware and can prevent zinc splashing caused by zinc dripping directly into the galvanizing pool.

[0021] 4. In this solution, the connecting block rotates and enters the second transverse groove to prevent the first extrusion block from being blocked. After the first extrusion block leaves, the rotating rod and the connecting block return to their original positions under the action of the torsion spring. During the process of the first extrusion block returning to its original position, the first extrusion block continues to squeeze the connecting block, so that the connecting block can rotate repeatedly with the rotating rod. During the rotation of the rotating rod, the rotating rod moves with the stirring rod inside the galvanizing pool, which is convenient for stirring the zinc inside the galvanizing pool, so that the heating and melting effect of the zinc inside the galvanizing pool is better.

[0022] 5. In this scheme, the scraper is made of aluminum so that the scraper can float on the zinc surface inside the galvanizing pool. As the zinc in the galvanizing pool is lost, the level of zinc in the galvanizing pool gradually decreases. The density of the scraper is less than that of zinc, and a cavity is opened inside the scraper, which makes it convenient for the scraper to always float on the surface of the zinc. The melting point of aluminum is greater than that of zinc, which prevents the scraper from melting, so that the scraper can clean the galvanizing pool with different degrees of zinc loss, and it is more convenient to push away impurities on the surface of zinc in the galvanizing pool.

[0023] 6. In this scheme, when the scraper reaches the side of the galvanizing pool, the inner wall of the galvanizing pool squeezes the second extrusion block, causing the second extrusion block to rotate with the flip plate, so that the cavity inside the scraper is connected with the interior of the galvanizing pool, which facilitates the impurities on the zinc surface in the galvanizing pool to reach the inside of the cavity through the flip plate. When the zinc inside the galvanizing pool is lost to a certain extent, the zinc in the galvanizing pool needs to be replenished. As the zinc in the galvanizing pool increases, the scraper moves upward with the collecting plate due to buoyancy, so that the collecting plate reaches the position of the extending slot, indicating that the zinc capacity inside the galvanizing pool has reached its maximum value at this time. When the collecting plate coincides with the extending slot, the collecting plate leaves the inside of the scraper under the action of the second spring, making the movement of the collecting plate more convenient.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 to Figure 2 , Figure 5 and Figures 8 to 9A hardware surface treatment device includes a galvanizing pool 2. Zinc is put into the pool, and the zinc is heated to 500°C inside the galvanizing pool 2 (the heating of the galvanizing pool is in the prior art and will not be elaborated here). The zinc melts in the galvanizing pool 2 and is in a liquid state. A pressing mechanism 1 is fixedly connected to the top of the galvanizing pool 2. A hydraulic cylinder is fixed at the bottom of the pressing mechanism 1. A pressing plate 11 is movably connected below the pressing mechanism 1. The hydraulic cylinder below the pressing mechanism 1 is connected to the top of the pressing plate 11. A hook hole 12 is provided on the surface of the pressing plate 11. The hook hole 12 is convenient for hanging hardware connected to the hook under the pressing plate 11 by using the hook hole 12. The pressing plate 11 moves with the hardware to the inside of the galvanizing pool 2 during the pressing process, so that the hardware enters the molten zinc and the surface of the hardware is galvanized. A cleaning mechanism 3 is provided inside the galvanizing pool 2. The cleaning mechanism 3 includes a connecting portion 12 connected to the top of the galvanizing pool 2. The guide member 31 has a surface that is slidably connected to a guide plate 311 on the surface of the galvanizing pool 2. The guide plate 311 is moved so that the guide plate 311 moves on the surface of the galvanizing pool 2. The bottom of the guide plate 311 is fixedly connected to a limit plate 312. A discharge member 33 is provided at the bottom of the limit plate 312. The discharge member 33 includes a scraper 331 that is slidably connected to the bottom of the limit plate 312. The guide plate 311 is moved with the limit plate 312 by the movement of the guide plate 311. The movement of the limit plate 312 can move the scraper 331 with it, so that the scraper 331 moves laterally inside the galvanizing pool 2, so that the scraper 331 can move impurities on the surface of the molten zinc in the galvanizing pool 2 to both sides of the galvanizing pool 2 to prevent the impurities on the surface of the zinc from adhering to the surface of the hardware when the hardware enters the zinc in the galvanizing pool 2, resulting in impurities in the plating layer on the surface of the hardware, resulting in poor corrosion protection and other beneficial effects of the hardware.

[0028] like Figure 1 to Figure 2 , Figure 5 and Figures 7 to 9As shown, a driving member 32 is arranged between the lower pressing plate 11 and the guide plate 311, and the driving member 32 includes a connecting rod 321 rotatably connected to the top of the lower pressing plate 11, and the connecting rod 321 moves downward when the lower pressing plate 11 moves downward, and a slider 322 is rotatably connected to the bottom of the connecting rod 321, and when the connecting rod 321 moves downward, the connecting rod 321 can move with the slider 322, and a first slide groove 25 is provided at the top of the galvanizing pool 2 corresponding to the lateral movement track of the slider 322, and the slider 322 moves inside the first slide groove 25, so that the slider 322 can move laterally at the top of the galvanizing pool 2 more stably, and the rear side of the slider 322 is connected to the guide plate 311, so that the slider 322 can move with the guide plate 311 during the movement of the slider 322 inside the first slide groove 25, so that the movement of the guide plate 311 is more convenient, and the movement of the guide plate 311 brings the scraper 331 more conveniently , and when the lower pressing plate 11 does not move downward, the guide plate 311 blocks the top opening of the galvanizing pool 2 to prevent the heat inside the galvanizing pool 2 from being lost, and when the hardware is hung at the bottom of the lower pressing plate 11, when the hardware falls, the hardware falls on the surface of the guide plate 311 to prevent the molten zinc inside the galvanizing pool 2 from splashing out when the hardware falls into the galvanizing pool 2, causing injury to the staff, making it safer for the staff to hang the hardware. A first spring 323 fixedly connected to the slider 322 is provided inside the first chute 25. When the guide plate 311 blocks the top of the galvanizing pool 2, the first spring 323 is in a naturally stretched state. When the slider 322 moves, the first spring 323 can be changed from a naturally tight state to a stretched state, so that after the lower pressing plate 11 moves upward, the slider 322 returns to its original position under the pull of the first spring 323, so that the driving member 32 can be reused.

[0029] like Figure 1 to Figure 2 , Figure 5 and Figure 7As shown, a first guide groove 315 is provided on a side of the guide plate 311 close to the scraper 331. When the hardware leaves the galvanizing pool 2 and moves upward to its original position, the guide plate 311 returns to its original position under the action of the driving member 32. The guide plate 311 blocks the top of the galvanizing pool 2, and the molten zinc on the surface of the hardware drips downward. The molten zinc drips into the inside of the guide plate 311. The inside of the guide plate 311 gradually decreases in height from the side close to the connecting rod 321 to the side away from the connecting rod 321, so that the dripping zinc moves to the side of the guide plate 311 away from the scraper 331 under the action of gravity and the inclination of the surface of the guide plate 311. The front and rear of the first guide groove 315 are The distance between the two sides is the same as the internal width of the guide plate 311, so that the zinc inside the guide plate 311 will always reach the inside of the first guide groove 315. The first guide groove 315 extends downwardly from the side of the scraper 331 to form multiple second guide grooves 316, so that the zinc inside the first guide groove 315 can reach the bottom of the second guide groove 316 under the guidance of the guide plate 311. The ends of the multiple second guide grooves 316 away from the first guide groove 315 are all provided with round holes 314 that penetrate the guide plate 311. The zinc follows the second guide grooves 316 to reach the inside of the galvanizing pool 2, which is convenient for recycling excess zinc on the surface of the hardware and can prevent zinc from directly dripping into the inside of the galvanizing pool 2 and causing zinc splashing.

[0030] like Figure 1 to Figure 2 , Figures 5 and 6 and Figures 8 to 10As shown, the front and rear sides of the bottom of the guide plate 311 extend downward to form a first extrusion block 317. During the movement of the guide plate 311, the guide plate 311 moves with the first extrusion block 317 inside the galvanizing pool 2. The inner wall of the galvanizing pool 2 is provided with a stirring member 34. The stirring member 34 includes a rotating rod 342 rotatably connected to the galvanizing pool 2. The top of the rotating rod 342 is rotatably connected to the galvanizing pool 2 through a torsion spring and a rotating shaft combined reset mechanism. Since the connection between the rotating rod 342 and the galvanizing pool 2 is located at the top of the galvanizing pool 2, the molten zinc inside the galvanizing pool 2 is prevented from affecting the rotation of the rotating rod 342. A first longitudinal groove 22 accommodating the rotation of the rotating rod 342 is provided inside the galvanizing pool 2 at a rotation position corresponding to the rotating rod 342. A connecting block 344 is fixedly connected to the top of the rotating rod 342. The connecting block 344 and the first extrusion block 317 are in the same horizontal plane. When the first extrusion block 317 moves, the first extrusion block 317 squeezes the connecting block 344. The connecting block 344 is made to move with the rotating rod 342 inside the galvanizing pool 2. A second transverse groove 23 is provided inside the galvanizing pool 2 at a position corresponding to the connecting block 344, so that the connecting block 344 can enter the second transverse groove 23 after rotating to prevent the first extrusion block 317 from being blocked. After the first extrusion block 317 leaves, the rotating rod 342 and the connecting block 344 return to their original positions under the action of the torsion spring. During the process of the first extrusion block 317 returning to its original position, the first extrusion block 317 continues to squeeze the connecting block 344, so that the connecting block 344 can rotate repeatedly with the rotating rod 342. A stirring rod 341 is fixedly connected to the bottom of the rotating rod 342. A first transverse groove 21 is provided inside the galvanizing pool 2 at a position corresponding to the stirring rod 341. During the rotation of the rotating rod 342, the rotating rod 342 moves with the stirring rod 341 inside the galvanizing pool 2, so that the zinc inside the galvanizing pool 2 is stirred conveniently, so that the zinc heating and melting effect inside the galvanizing pool 2 is better.

[0031] like Figures 2 to 6 As shown, the scraper 331 is fixedly connected with the first extension block 332 inside, and the limiting plate 312 is provided with a limiting groove 313 corresponding to the position of the first extension block 332 to accommodate the movement of the first extension block 332. The first extension block 332 moves inside the limiting groove 313, so that the scraper 331 can move up and down under the limiting plate 312, making the movement of the scraper 331 more convenient. The scraper 331 is provided with a cavity 333 inside. The scraper 331 is made of aluminum, so that The scraper 331 can float on the zinc surface inside the galvanizing pool 2. As the zinc in the galvanizing pool 2 is lost, the level of zinc in the galvanizing pool 2 gradually decreases. The density of the scraper 331 is less than that of zinc, and a cavity 333 is provided inside the scraper 331, which facilitates the scraper 331 to always float on the zinc surface. The melting point of aluminum is greater than that of zinc, which prevents the scraper 331 from melting, so that the scraper 331 can clean the galvanizing pool 2 with different degrees of zinc loss, and it is more convenient to push away impurities on the surface of zinc in the galvanizing pool 2.

[0032] like Figures 2 to 6 and Fig.11 As shown, the scraper 331 is rotatably connected to the flip plate 338 on one side close to the galvanizing pool 2. During the movement of the scraper 331, the scraper 331 moves with the flip plate 338. The flip plate 338 is fixedly connected to the second extrusion block 339 on the side away from the limit plate 312. When the scraper 331 reaches the side of the galvanizing pool 2, the inner wall of the galvanizing pool 2 squeezes the second extrusion block 339, so that the second extrusion block 339 rotates with the flip plate 338, so that the cavity 333 inside the scraper 331 is connected to the inside of the galvanizing pool 2, so that the impurities on the zinc surface in the galvanizing pool 2 are conveniently removed through the flip plate 338. The bottom of the cavity 333 is slidably connected with a collecting plate 334, so that impurities on the surface of the galvanizing pool 2 can reach the inside of the collecting plate 334 for collection. The rear side of the galvanizing pool 2 is provided with an extension slot 24. When the zinc inside the galvanizing pool 2 is lost to a certain extent, the zinc in the galvanizing pool 2 needs to be supplemented. As the zinc in the galvanizing pool 2 increases, the scraper 331 moves upward with the collecting plate 334 due to buoyancy, so that the collecting plate 334 reaches the position of the extension slot 24. A top-down flip door is installed on the rear side of the galvanizing pool 2 to prevent zinc from being drawn out during galvanizing. The collecting plate 334 extends out of the galvanizing pool 2, and the collecting plate 334 extends out of the galvanizing pool 2, indicating that the zinc capacity inside the galvanizing pool 2 has reached the maximum value at this time. The bottom of the collecting plate 334 extends downward to form a second extension block 335. The scraper 331 has a second chute 336 corresponding to the moving track of the second extension block 335, which facilitates the second extension block 335 to move inside the second chute 336, so that the collecting plate 334 can move inside the scraper 331. The movement of the collecting plate 334 can make the collecting plate 334 move from the scraper 331. The collecting plate 334 extends out from the inside of the galvanizing pool 2, and the collecting plate 334 reaches the outside of the galvanizing pool 2 through the extending groove 24. The impurities in the collecting plate 334 arrive at the outside of the galvanizing pool 2 along with the collecting plate 334, which facilitates the cleaning of the impurities collected in the collecting plate 334. A second spring 337 is provided on the front side of the collecting plate 334. The second spring 337 is in a taut state when the collecting plate 334 is in the galvanizing pool 2. When the collecting plate 334 coincides with the extending groove 24, the collecting plate 334 leaves from the inside of the scraper 331 under the action of the second spring 337, making the movement of the collecting plate 334 more convenient.

[0033] The above are only preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
