Description

Technical Field

[0001] This utility model relates to the field of rust removal and polishing with alloy steel shot, specifically an alloy steel shot rust removal and polishing device. Background Technology

[0002] Alloy steel shot is a high-quality wear-resistant material. It possesses moderate hardness, high toughness, excellent impact resistance, and a long service life. In the production of alloy steel shot, molten steel is centrifugally thrown into water to form steel shot. The steel shot needs to be heated and dried to remove moisture. However, this drying process generates oxide scale on the surface of the steel shot, causing surface corrosion and affecting its quality. Therefore, rust removal and polishing equipment is required to treat the surface of the steel shot.

[0003] In the prior art, such as in publication number CN220007322U, an alloy steel shot rust removal and polishing device is disclosed. It includes a support plate, an outer shell above the support plate, an inner shell rotatably installed inside the outer shell, a horizontal plate fixedly installed on the inner wall of the inner shell, a shell cover at one end of the inner shell, a feed port at the axis of the shell cover, a leak-proof ring fixedly installed at one end of the shell cover near the inner shell, and an intermittent drive mechanism connected to the other end of the inner shell. This utility model uses an intermittent drive mechanism to make the inner shell continuously cycle between a high-speed rotation state and a deceleration state. The steel shot inside the inner shell is continuously driven by the horizontal plate and is thrown out as the horizontal plate decelerates. This not only intensifies the collision and friction between the steel shot, making the rust removal and polishing effect of the steel shot better, but also avoids the inner shell being in a high-speed rotation state, which would cause excessive centrifugal force and cause the steel shot to stick to the inner wall of the inner shell, affecting the collision between the steel shot.

[0004] Although the aforementioned patent improves the rust removal effect through an intermittent drive mechanism, it still relies solely on the impact of multiple alloy balls during rotation to remove rust, resulting in low efficiency and a lack of other structures to increase rust removal efficiency. Furthermore, the dust and debris generated after rust removal remain inside the rust removal structure, making cleaning quite cumbersome. Therefore, an alloy steel shot rust removal and polishing device is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, which still rely solely on the impact of multiple alloy balls during rotation for rust removal, resulting in low efficiency and a lack of other structures to increase rust removal efficiency, this invention proposes an alloy steel shot rust removal and polishing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The alloy steel shot rust removal and polishing device of this utility model includes a base, and a flexible support block is symmetrically and fixedly connected to the top surface of the base. A left support plate is fixedly connected to the top surface of one of the flexible support blocks, and a right support plate is fixedly connected to the top surface of the other flexible support block. A drive motor is fixedly connected to the back of the left support plate. The output end of the drive motor passes through the left support plate and is fixedly connected to a connecting component. A processing component is fixedly connected to the side of the connecting component. A U-shaped opening extending to the top surface is opened at the top of the right support plate.

[0007] The connecting assembly includes a connecting block fixedly connected to the output end of the drive motor. A support plate is provided on the bottom surface of the connecting block. Limiting holes are opened on the sides of the connecting block and the support plate. A limiting rod is inserted into the limiting hole. Elastic limiting strips are inserted into the insertion holes at both ends of the limiting rod.

[0008] The processing assembly includes a processing barrel fixed to the side of a pallet. The inner wall of the processing barrel is fixed with protruding strips and a polishing layer in a circular array. A cover plate is connected to the back of the processing barrel via a hinge. A locking block is fixed to the side of the cover plate. A locking handle is provided on the surface of the locking block and is fixed to the side of the processing barrel. A connecting plate is fixed to the bottom of the processing barrel. A vibration motor is symmetrically fixed to the bottom of the connecting plate. The bottom of the vibration motor is connected to the base surface via a spring. A rotating block that matches the U-shaped opening of the right support plate is fixed to the side of the cover plate.

[0009] Preferably, the processing barrel is fixedly connected to the vibration motor via a connecting plate, and the vibration motor is elastically supported on the base surface by springs.

[0010] Preferably, the cover plate is rotatably connected to the processing bucket via a hinge, and the snap-fit ​​handle and the snap-fit ​​block are detachably snapped together to fix the cover plate.

[0011] Preferably, the raised strips and polishing layer on the inner wall of the processing barrel are alternately distributed circumferentially.

[0012] Preferably, the connecting block and the support plate are detachably connected by a limiting rod and an elastic limiting strip.

[0013] Preferably, the rotating block is rotatably disposed within the U-shaped opening of the right support plate.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through the structural design of setting annular alternating convex strips and polishing layers on the inner wall of the processing barrel, combined with a drive motor to drive the processing barrel to rotate and a vibration motor to generate vibration by being elastically supported on the base surface by springs, achieves the effect of alloy steel shot violently colliding with the convex strips to peel off the rust layer under the dual action of rotational centrifugal force and high-frequency vibration. At the same time, the circumferentially alternating polishing layer continuously rubs and polishes the surface of the steel shot, significantly improving the rust removal efficiency and surface smoothness, and solving the problem of low efficiency caused by the single reliance on rotational impact in the existing technology;

[0016] 2. This utility model, through the structural design of detachable connecting components and openable cover plates, allows for quick assembly and disassembly of the connecting block and support plate via limiting rods and elastic limiting strips.

Combined with the rotational cooperation of the rotating block and the U-shaped opening of the right support plate, the processing barrel can be easily detached from the drive motor and the right support plate, achieving efficient cleaning of dust and debris inside the processing barrel, avoiding the accumulation of residues that affect the quality of subsequent processing, and solving the technical defects of cumbersome internal cleaning in existing devices.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, an alloy steel shot rust removal and polishing device includes a base 1. Flexible support blocks 2 are symmetrically fixedly connected to the top surface of the base 1. A left support plate 3 is fixedly connected to the top surface of one flexible support block 2, and a right support plate 7 is fixedly connected to the top surface of the other flexible support block 2. A drive motor 6 is fixedly connected to the back of the left support plate 3. The output end of the drive motor 6 passes through the left support plate 3 and is fixedly connected to a connecting assembly 4. A processing assembly 5 is fixedly connected to the side of the connecting assembly 4. A U-shaped opening extending to the top surface is provided at the top of the right support plate 7. The processing assembly 5 includes a treatment component fixed to the side of a support plate 42. The inner wall of the processing tank 51 is fixed with protruding strips 52 and polishing layer 53 in a ring array. The back of the processing tank 51 is connected to the cover plate 55 by the hinge 54. The side of the cover plate 55 is fixed with the locking block 56. The surface of the locking block 56 is provided with the locking handle 57. The locking handle 57 is fixed to the side of the processing tank 51. The bottom surface of the processing tank 51 is fixed with the connecting plate 58. The bottom surface of the connecting plate 58 is symmetrically fixed with the vibration motor 59. The bottom surface of the vibration motor 59 is connected to the surface of the base 1 by the spring 510. The side of the cover plate 55 is fixed with the rotating block 511 that matches the U-shaped opening of the right support plate 7.

[0025] During operation, the drive motor 6 is started to drive the connecting assembly 4 to rotate. The connecting block 41 is fixed to the support plate 42 by the limiting rod 43 and the elastic limiting strip 44, driving the processing barrel 51 to rotate around the axis. Simultaneously, the vibration motor 59 is started to transmit high-frequency vibration to the processing barrel 51 through the spring 510. The flexible support block 2 and the spring 510 together provide vibration freedom for the processing barrel 51. Under the action of rotational centrifugal force and vibration, the alloy steel shot bounces at high frequency in the processing barrel 51 and violently collides with the annularly distributed convex strips 52 on the inner wall to peel off the rust layer. At the same time, during the rotation, the steel shot continuously rubs and polishes the circumferential grinding layer 53, achieving efficient rust removal and surface finishing.

[0026] Furthermore, the connecting component 4 includes a connecting block 41 fixedly connected to the output end of the drive motor 6. A support plate 42 is provided on the bottom surface of the connecting block 41. Limiting holes are opened on the sides of the connecting block 41 and the support plate 42. A limiting rod 43 is inserted into the limiting hole. An elastic limiting strip 44 is inserted into the insertion holes at both ends of the limiting rod 43.

[0027] During operation, when disassembling the processing bucket 51, pull out the elastic limiting strip 44 and remove the limiting rod 43 to release the fixing of the connecting block 41 and the support plate 42; loosen the engagement between the locking handle 57 and the locking block 56, flip the cover plate 55 around the hinge 54 to open the processing bucket 51, and at the same time move the rotating block 511 on the side of the cover plate 55 out of the U-shaped opening of the right support plate 7, so that the processing bucket 51 is freed from the constraints of the drive motor 6 and the right support plate 7; after cleaning the internal dust and debris, reverse the operation to reset the rotating block 511 to the U-shaped opening, close the cover plate 55 and lock the locking handle 57, and reinsert the limiting rod 43 and the elastic limiting strip 44 to complete the rapid assembly of the processing bucket 51, ensuring continuous operation efficiency.

[0028] Furthermore, the cover plate 55 is rotatably connected to the processing bucket 51 via a hinge 54, and the snap-on handle 57 and the snap-on block 56 are detachably snapped together to fix the cover plate 55.

[0029] During operation, rotating the latch handle 57 outward disengages it from the latch block 56, allowing the cover 55 to be flipped around the hinge 54 axis to the fully open state, exposing the interior of the treatment tank 51. After cleaning, rotating the cover 55 in the opposite direction closes it, and the latch handle 57 and latch block 56 elastically engage and lock together to ensure a tight seal. This structure, through its integrated design of rotational opening and closing and latching fixation, simplifies the opening and closing process of the cover 55, improves the convenience of cleaning operations, and avoids the time-consuming and labor-intensive problems of traditional bolt fixing methods, significantly improving maintenance efficiency.

[0030] Furthermore, the raised strips 52 and the polishing layer 53 on the inner wall of the treatment barrel 51 are alternately distributed in the circumferential direction;

[0031] During operation, when the drive motor 6 rotates the processing tank 51, the alloy steel shot adheres tightly to the inner wall under centrifugal force. The protrusions 52 intermittently impact the steel shot to remove the rust layer, while the adjacent polishing layer 53 continuously rubs and polishes the surface of the steel shot. The superimposed vibration of the vibration motor 59 further intensifies the contact frequency between the steel shot and the protrusions 52 and the polishing layer 53. This alternating distribution structure integrates the functions of impact rust removal and friction polishing into the same processing tank 51, which improves the uniformity of surface treatment, shortens the processing cycle, and overcomes the limitations of a single structure function through synergistic effect.

[0032] Furthermore, the connecting block 41 and the support plate 42 are detachably connected by the limiting rod 43 and the elastic limiting strip 44;

[0033] During operation, the connecting block 41 and the tray 42 are aligned through the transverse through-hole and then inserted into the limiting rod 43. The elastic limiting strip 44 is inserted into the holes at both ends of the limiting rod 43 to achieve axial locking. When disassembling, simply pull out the elastic limiting strip 44 and pull out the limiting rod 43 to separate the connecting block 41 and the tray 42. This detachable structure allows the connection between the processing tank 51 and the output end of the drive motor 6 to be made without the aid of tools, enabling quick disassembly and assembly. It facilitates the overall disassembly, cleaning or replacement of the processing tank 51, reduces equipment downtime, and adapts to the needs of continuous production.

[0034] Furthermore, the rotating block 511 is rotatably disposed within the U-shaped opening of the right support plate 7;

[0035] During operation, the rotating block 511 on the side of the cover plate 55 is embedded in the U-shaped opening at the top of the right support plate 7. During installation, after the rotating block 511 is vertically inserted along the U-shaped opening, the processing barrel 51 rotates freely around the axis of the rotating block 511, forming a stable linkage with the drive motor 6 on the side of the left support plate 3. During disassembly, the processing barrel 51 is lifted vertically to disengage the rotating block 511 from the U-shaped opening. This structure, through the matching design of the U-shaped opening and the rotating block 511, ensures the radial freedom of the processing barrel 51 during rotation and achieves rapid axial positioning and separation, avoiding the complex assembly of traditional bearing support structures, reducing maintenance costs and improving the modularity of the equipment.

[0036] Working principle: The drive motor 6 is rigidly connected to the support plate 42 through the connecting block 41 in the connecting assembly 4, driving the processing barrel 51 to rotate around the axis. At the same time, the vibration motor 59 transmits high-frequency vibration to the processing barrel 51 through the spring 510. The flexible support block 2 and the spring 510 together form an elastic support system, so that the processing barrel 51 undergoes multi-dimensional vibration during rotation. Under the action of centrifugal force, the alloy steel shot adheres tightly to the inner wall of the processing barrel 51. It is impacted by the circumferentially alternating convex strips 52 to peel off the rust layer, and then rolls and rubs along the surface of the polishing layer 53 to achieve polishing. This increases the frequency of steel shot bouncing and the intensity of contact with the inner wall. After processing, the elastic limiting strip 44 of the connecting component 4 is pulled out and the limiting rod 43 is removed, the connection between the processing barrel 51 and the drive motor 6 is released, the locking handle 57 is unscrewed to release the cover plate 55, the cover plate 55 is flipped around the hinge 54 and the U-shaped opening between the rotating block 511 and the right support plate 7 is removed, so as to achieve the overall separation of the processing barrel 51 and the cleaning of internal debris. After resetting, the equipment is quickly reassembled through the limiting rod 43 and the elastic limiting strip 44 to form a high-efficiency rust removal and polishing cycle that integrates rotation, vibration, disassembly and cleaning.
