Description

Technical Field

[0001] This utility model relates to the field of stainless steel surface finishing technology, and in particular to a surface finishing device for stainless steel casting production. Background Technology

[0002] Stainless steel castings refer to metal parts with specific shapes and performance requirements made from stainless steel through casting processes. Stainless steel is an alloy steel with good corrosion resistance, high strength, and good ductility. It typically contains a high proportion of chromium, which forms a dense oxide film on the surface, effectively resisting oxidation and chemical corrosion. Stainless steel castings are widely used in petrochemical, machinery, shipbuilding, food, medical, and aerospace industries, and are commonly used to manufacture critical components such as valve bodies, pump housings, impellers, and pipe fittings. Their advantages include strong process adaptability, the ability to cast complex structural parts, superior mechanical properties, and long service life. In actual production, stainless steel castings are generally produced using investment casting, shell casting, or precision casting processes to meet different structural and performance requirements.

[0003] Before deep processing of stainless steel castings, surface finishing equipment is needed to thoroughly remove residual sand particles, oxide scale, burrs, and other impurities from their surface to avoid affecting the quality of subsequent processing. However, existing surface finishing equipment generally relies on abrasive belts with fixed tension, making it difficult to adaptively adjust the tension of the abrasive belt to suit the different convex and concave shapes of the casting surface. At the same time, there is a lack of effective cleaning mechanisms to remove accumulated metal debris from the surface of the abrasive belt. This causes the abrasive belt to wear faster under high load conditions, and the continuous adhesion of metal residue not only reduces the polishing efficiency of the abrasive belt but also causes scratches and uneven grinding in subsequent grinding, resulting in unstable surface finishing quality of stainless steel castings.

[0004] Therefore, there is an urgent need for a surface finishing device capable of adjusting the tension of the abrasive belt in real time and simultaneously removing debris from the belt surface to meet the production requirements of efficient and precise machining of stainless steel castings. Based on this, we propose a surface finishing device for stainless steel casting production. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Refer to Figures 1 to 5This utility model provides an embodiment of a surface finishing device for stainless steel casting production, comprising a support frame 1, a surface finishing component 2 disposed on the inner side of the support frame 1, a casting substrate 3 placed at the bottom of the support frame 1, and a triangular side plate 4. A motor transmission box 5 is mounted on one side of the triangular side plate 4, and a transmission roller 6 is connected to the side of the triangular side plate 4 away from the motor transmission box 5. Both sets of transmission rollers 6 are connected to the motor transmission box 5 through transmission. A guide roller 7 is connected to the middle of the side of the triangular side plate 4 near the transmission roller 6. A grinding belt 8 is also connected between the two sets of transmission rollers 6 and the guide roller 7 through transmission. This surface finishing device is connected via a first groove 12, a first guide rod 13, and a first compression spring. The cooperation between the springs 14 allows the guide rollers 7 to adjust the tension of the grinding belt 8 in real time according to the unevenness of the stainless steel casting surface. This ensures a tight fit between the grinding belt 8 and the casting surface, effectively improving the grinding efficiency and quality of the grinding belt 8 on the casting substrate 3. It also reduces wear caused by uneven tension of the grinding belt 8. An elastic adjustment component 9 is provided on the side of the triangular side plate 4 near the guide rollers 7. Cleaning components 10 are provided on the side of the triangular side plate 4 near the two sets of transmission rollers 6. A guide plate 11 is also provided on the side of the triangular side plate 4 away from the elastic adjustment component 9. The guide plate 11 added to one side of the triangular side plate 4 is used for limiting connection and guiding adjustment between the triangular side plate 4 and the support frame 1.

[0020] The elastic adjustment component 9 includes a first slide groove 12, which is located on one side of the triangular side plate 4. A first guide rod 13 is slidably connected inside the first slide groove 12. The first guide rod 13 is movably connected to the guide roller 7. A first compression spring 14 is also connected between the first guide rod 13 and the first slide groove 12. Through the cooperation of the first slide groove 12, the first guide rod 13, and the first compression spring 14, the elastic adjustment component 9 can form an adaptive elastic adjustment structure. When the abrasive belt 8 contacts the surface of the casting substrate 3, the protruding part of the surface of the casting substrate 3 pushes the guide roller 7 upward, which can cause the first guide rod 13 to slide within the first slide groove 12 and compress the first compression spring 14. The concave part of the surface of the casting substrate 3 allows the guide roller 7 to return downward under the elastic force of the first compression spring 14, restoring the tension of the abrasive belt 8. Through this tension adjustment method, the abrasive belt 8 can automatically adjust its tightness according to the unevenness of the casting surface, ensuring that the abrasive belt 8 and the casting surface are in harmony. The surfaces fit tightly together, improving grinding efficiency and quality while reducing wear caused by uneven belt tension. This allows for adaptive adjustment of belt tension during grinding, ensuring consistent and stable grinding results. The cleaning component 10 includes a support plate 15, with multiple sets of second guide rods slidably connected to its center. A cleaning scraper 17 is installed between one end of each set of second guide rods 16. The cleaning scraper 17 is in contact with the grinding belt 8. The outer side of the end of each set of second guide rods 16 closest to the cleaning scraper 17 is also present. A second compression spring 18 is also provided. The cleaning component 10, through the cooperation between the support plate 15, the second guide rod 16, the cleaning scraper 17, and the second compression spring 18, as well as the structural design of the contact cooperation between the cleaning scraper 17 and the abrasive belt 8, can remove metal debris and impurities attached to the surface of the abrasive belt 8 in real time during the polishing process, realize the automation of the cleaning process, avoid secondary scratches and uneven polishing caused by debris accumulation, thereby significantly improving the polishing quality and extending the service life of the abrasive belt 8.

[0021] A forward and reverse drive box 19 is installed on the top of the support frame 1. A second slide groove 20 is opened on the inner side of the support frame 1. The second slide groove 20 is slidably engaged with the guide plate 11. An adjusting screw 21 is connected to the inside of the second slide groove 20 through a bearing. The adjusting screw 21 is driven by the forward and reverse drive box 19. The adjusting screw 21 is threadedly engaged with the guide plate 11. Through the structural design of the sliding engagement between the second slide groove 20 and the guide plate 11 and the threaded engagement between the adjusting screw 21 and the guide plate 11, the support frame 1 can adjust the height of the surface processing component 2 according to the usage. It can adapt to the processing of casting substrates 3 of different heights, ensuring that the grinding belt 8 can accurately contact the casting surface, improving the versatility and operational flexibility of the device, and realizing the processing of different specifications. For efficient and precise grinding of the casting, the support frame 1 has a third sliding groove 22 at its bottom and two sets of clamping bases 23 at its bottom. The two sets of clamping bases 23 are slidably fitted with the third sliding groove 22. The interior of the third sliding groove 22 is connected to a positive and negative screw 24 through a bearing. The positive and negative screw 24 are threadedly fitted with the two sets of clamping bases 23. Through the structural design of the threaded fit between the positive and negative screw 24 and the two sets of clamping bases 23, the two sets of clamping bases 23 can be driven to move synchronously in the same or opposite directions when the positive and negative screw 24 rotates. This allows for flexible clamping or loosening of the casting base 3, adapting to stainless steel castings of different widths and ensuring stable positioning during the grinding process. This achieves efficient and adjustable clamping and stable and reliable processing.

[0022] Working Principle: The surface finishing device designed in this scheme can achieve adaptive adjustment of the tension of the grinding belt 8 by setting up an elastic adjustment component 9 and a guide roller 7. The elastic adjustment component 9, through the cooperation of the first slide groove 12, the first guide rod 13 and the first compression spring 14, enables the guide roller 7 to adjust the tightness of the grinding belt 8 in real time according to the unevenness of the stainless steel casting surface. This ensures that the grinding belt 8 is in close contact with the casting surface, effectively improving the grinding efficiency and quality of the grinding belt 8 on the casting substrate 3. At the same time, it can also reduce the wear of the grinding belt 8 caused by uneven tension, extend the service life of the grinding belt 8 and reduce production costs.

[0023] The surface finishing device designed in this scheme, through the cooperation of the support plate 15, the second guide rod 16, the cleaning scraper 17, and the second compression spring 18, can continuously remove metal debris adhering to the surface of the grinding belt 8 during the grinding process. The cleaning component 10, through the contact cooperation between the cleaning scraper 17 and the grinding belt 8, can effectively prevent secondary adhesion of debris, thereby extending the service life of the grinding belt 8 and ensuring the consistency and stability of subsequent grinding of the casting substrate 3. Through the cooperation between the forward and reverse drive box 19 and the adjusting screw 21, the guide plate 11 and the surface finishing component 2 can be moved along the height direction of the support frame 1 to achieve adaptive processing of castings of different heights. In addition, the two sets of clamping bases 23 set at the bottom of the support frame 1 can also be flexibly adjusted in position according to the size and shape of the casting substrate 3 through the drive of the forward and reverse screws 24, providing a stable clamping force, further improving the versatility and ease of operation of the device, and realizing efficient and precise surface finishing of stainless steel castings.
