Description

Technical Field

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

[0002] Stainless steel castings are widely used in industrial production, but their surfaces often have various defects, such as oxide scale, oil stains, and rust. These defects not only affect the appearance of the castings, but may also reduce their corrosion resistance and mechanical properties.

[0003] A shot blasting machine is a device that uses a high-speed rotating shot blaster to propel steel shot or grit onto the surface of a workpiece to remove surface dirt, oxide layers, rust, and other impurities, achieving a certain degree of roughness and strengthening effect. This equipment has wide applications in the metal processing industry, especially in the surface treatment of stainless steel castings.

[0004] The existing method involves hanging stainless steel castings on the suspension frame or rod inside the shot blasting machine. After processing, each casting needs to be removed manually. This is not only labor-intensive but also carries the risk of injury from falling castings. Furthermore, it is inefficient and delays subsequent use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, after stainless steel castings are hung on the suspension frame or suspension rod inside the shot blasting machine, they need to be removed manually one by one after processing. This not only involves a large amount of labor, but also poses a certain risk of injury from falling castings. Therefore, this invention proposes a surface treatment device for processing stainless steel castings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface treatment device for processing stainless steel castings includes a housing, on one side of which multiple shot blasters are installed.

[0008] A placement rack for placing stainless steel castings is located inside a housing. The placement rack includes an outer rod and an inner rod. The inner rod is slidably disposed inside the outer rod. The outer wall of the inner rod has multiple sets of vertically arranged side grooves, and each set of side grooves has multiple slots. A crossbar is fixedly disposed on the top of the inner wall of the side groove. A hanging rod is rotatably sleeved on the outer wall of the crossbar. The outer wall of the outer rod has multiple sets of vertically arranged side holes, and each set of side holes has multiple holes. The hanging rod extends to the outside through adjacent side holes.

[0009] A drive assembly for moving the outer rod is located on the top of the housing.

[0010] In one possible design, the drive assembly includes a primary servo motor, a bracket is fixedly mounted on the top of the housing, the primary servo motor is fixedly mounted on one side of the bracket, a threaded rod is rotatably mounted inside the bracket, one end of the threaded rod rotatably passes through the bracket and is fixedly mounted to the output shaft of the primary servo motor, and a mounting plate is slidably mounted on the bottom of the bracket, with the mounting plate threaded onto the outer wall of the threaded rod.

[0011] In one possible design, the drive assembly further includes a second servo motor, which is fixedly mounted on the bottom of the mounting plate. A sliding hole is provided on the top of the housing, and a sliding plate is slidably mounted inside the sliding hole. Two extension plates are fixedly mounted on the top of one side of the housing, and the sliding plate is slidably mounted between the two extension plates. The sliding plate is rotatably sleeved on the outer wall of the outer rod, and the top end of the outer rod is fixedly mounted to the output end of the second servo motor.

[0012] In one possible design, the placement rack further includes a locking rod. The outer wall of the inner rod has a sliding cavity, and the locking rod is slidably disposed inside the sliding cavity. A compression spring is disposed inside the locking rod, and the two ends of the compression spring are respectively fixedly disposed at one end of the locking rod and one side of the inner wall of the sliding cavity. The other end of the locking rod slides through the outer rod. The top of the two extension plates is fixedly disposed on the same upright plate, and a top rod is fixedly disposed on one side of the upright plate, and the top rod cooperates with the locking rod.

[0013] In one possible design, a torsion spring is fitted on the outer wall of the crossbar, with the two ends of the torsion spring fixedly disposed on one side of the hanging rod and on one side of the inner wall of the side groove, respectively.

[0014] In one possible design, the multiple hanging rods are arranged in a ring at equal intervals.

[0015] In one possible design, hinged doors are provided on both sides of the opening of the housing.

[0016] In this application, during actual use, the first servo motor drives the threaded rod to rotate, which in turn drives the second servo motor to move. The second servo motor moves the outer rod between the two extension plates. At this point, the placement rack is outside the housing and can hang the stainless steel casting on the hanging rod. Then, the first servo motor is driven in reverse to reset and close the stop door. The shot blasting machine can then be turned on for surface treatment. The second servo motor drives the entire placement rack to rotate, ensuring that the stainless steel casting is treated evenly. After the treatment is complete, the stop door is opened, and the first servo motor drives the entire placement rack to move until it is on the extension plate. The process is controlled by... The angle causes the top rod to contact the locking rod, causing the locking rod to retract into the sliding cavity. At this point, the inner rod and outer rod are released from their fixed state, allowing the inner rod to slide. Since the inner rod is released from its fixed state, the hanging rod will rotate due to the weight of the stainless steel casting hanging at its end, causing the inner rod to move upward. The casting will also slide down. By placing a collection box or other tools at the bottom for collection, the overall processing efficiency is improved. After the casting falls, the hanging rod will be reset by the torsion spring, and the inner rod will also be reset by gravity falling downward. Then, the drive placement frame moves in the opposite direction a certain distance, causing the locking rod to lose its contact with the top rod and reset again by the compression spring, locking the inner rod and outer rod together.

[0017] In this utility model, the surface treatment equipment for stainless steel casting processing, through multiple rotatable hanging rods, can ensure that the casting is subjected to more uniform and comprehensive impact during shot blasting, thereby significantly improving the quality and uniformity of surface treatment;

[0018] In this utility model, the surface treatment equipment for stainless steel casting processing, through the adjustable placement rack, can achieve the following: after the processing is completed, the hanging rod used to hang the casting can tilt, so that the processed casting can slide directly into the collection box below, thereby reducing the corresponding amount of labor and eliminating the need for manual handling of each casting.

[0019] In this invention, after the stainless steel casting is scraped onto the hanging rod, it can be moved to the inside of the box by the drive assembly for surface treatment by the shot blasting machine. After the treatment is completed, the placement rack is moved to the designated position, and the hanging rod used to place the casting will tilt and slide into the pre-placed collection box below. There is no need to manually pick them up one by one, which reduces the amount of labor and improves efficiency. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1 A surface treatment device includes: a housing 1, a mounting rack, and a drive assembly.

[0029] The housing 1 serves as the main body of the entire equipment. Multiple shot blasters 6 are installed on one side of the housing, which are used to perform surface treatment on stainless steel castings, remove impurities such as oxide scale and rust from the surface of the castings, improve the roughness and cleanliness of the casting surface, and prepare for subsequent processing or painting processes.

[0030] Reference Figure 5 The placement rack, used to hold stainless steel castings, is located inside the housing 1. The rack includes an outer rod 7 and an inner rod 13, with the inner rod 13 slidably disposed inside the outer rod 7. The outer wall of the inner rod 13 has multiple sets of vertically arranged side grooves 19, each set having multiple side grooves 19. A crossbar 18 is fixedly mounted on the top of the inner wall of each side groove 19, and a hanging rod 8 is rotatably sleeved on the outer wall of the crossbar 18 for hanging the castings. The outer wall of the outer rod 7 has multiple sets of vertically arranged side holes 21, each set having multiple side holes 21. The hanging rod 8 extends to the outside through adjacent side holes 21.

[0031] This application can be used in the field of stainless steel casting processing, or in other fields applicable to this application.

[0032] Example 2

[0033] refer to Figure 1-2 An improvement based on Example 1: a surface treatment device for stainless steel casting processing, which is applied to the field of stainless steel casting processing, wherein the drive component is used to drive the outer rod 7 to move and rotate.

[0034] Servo motor 5 is fixedly mounted on one side of bracket 4. A threaded rod is rotatably mounted inside bracket 4, with one end of the threaded rod passing through bracket 4 and fixedly mounted to the output shaft of servo motor 5. A mounting plate is slidably mounted on the bottom of bracket 4, and the mounting plate is threaded onto the outer wall of the threaded rod. When servo motor 5 is started, the threaded rod rotates, causing the mounting plate to move horizontally.

[0035] The second servo motor 9 is fixedly mounted on the bottom of the mounting plate. The output end of the second servo motor 9 is fixedly connected to the top of the outer rod 7 through a coupling and other components to achieve all-round shot blasting of the casting. The top of the housing 1 is provided with a sliding hole 11, and a sliding plate 12 is slidably mounted inside the sliding hole 11. The sliding plate 12 is rotatably sleeved on the outer wall of the outer rod 7, serving as support and guidance.

[0036] Reference Figure 3-4 In addition, the mounting bracket includes a locking rod 10 for fixing the position of the inner rod 13 within the outer rod 7. A sliding cavity 15 is formed on the outer wall of the inner rod 13. The locking rod 10 is slidably disposed inside the sliding cavity 15. A compression spring 14 is disposed inside the locking rod 10, with its two ends fixed to one end of the locking rod 10 and one side of the inner wall of the sliding cavity 15, respectively, giving the locking rod 10 a tendency to pop outwards. The other end of the locking rod 10 slides through the outer rod 7, causing the inner rod 13 to engage with the outer rod 7 for fixation. A single upright plate 17 is fixedly disposed on the top of both extension plates 3, and a top rod 16 is fixedly disposed on one side of the upright plate 17.

[0037] Specifically, by driving servo motor 5 to rotate the threaded rod, servo motor 9 moves, which in turn moves outer rod 7 between the two extension plates 3. At this point, the placement rack is outside the housing 1, allowing the stainless steel casting to be hung on hanging rod 8. Then, servo motor 5 is driven in reverse to reset and the stop door 2 is closed. The shot blaster 6 is then turned on for surface treatment. Servo motor 9 drives the entire placement rack to rotate, ensuring the stainless steel casting is treated evenly. After the treatment is complete, the stop door 2 is opened, and servo motor 5 moves the entire placement rack until it reaches the extension plate 3. The angle is controlled so that the top rod 16 contacts the locking rod. 10, causing the locking rod 10 to retract into the sliding cavity 15. At this time, the inner rod 13 and the outer rod 7 will be released from their fixed state, and the inner rod 13 can slide. Since the inner rod 13 is released from its fixed state, the hanging rod 8 will rotate due to the weight of the stainless steel casting hanging at its end, causing the inner rod 13 to move upward. The casting will also slide down. By placing a collection box or other tools at the bottom for collection, the overall processing efficiency can be improved. After the casting falls, the hanging rod 8 will be reset by the torsion spring 20, and the inner rod 13 will also be reset by gravity falling downward again. Then, the drive placement frame will move in the opposite direction a certain distance, so that the locking rod 10 loses the contact with the top rod 16 and is reset again by the compression spring 14, locking the inner rod 13 and the outer rod 7 together.

[0038] Reference Figure 1 Both sides of the opening of the chamber 1 are hinged with baffles 2 to close the opening of the chamber 1 and prevent the shot from splashing and injuring people or polluting the environment during the shot blasting process.

[0039] After use, steel shot is collected using existing collection boxes or electromagnets, separated by size and impurities using vibrating screens, and then cleaned (e.g., by water washing or sandblasting) and inspected for quality (using hardness testers) before reuse to ensure that the steel shot meets the standards for reuse.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the shot blasting machine 6, the first servo motor 5, and the second servo motor 9 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
