Description

Technical Field

[0001] The present application relates to the technical field of steel component surface treatment, and in particular to a steel component surface treatment device and process. Background Art

[0002] Steel components often need surface treatment at the end of the production process. Among them, surface shot blasting is a more conventional surface treatment method. High-speed projectiles are thrown by shot blasting machines to clean or strengthen the surface of castings. Shot blasting technology is widely used in many industries such as steel manufacturing and mechanical processing, greatly improving product performance and market competitiveness.

[0003] The shot blasting machine in the related art usually includes a shot blasting channel of a box structure and a conveying frame passing through the shot blasting channel, on which a plurality of conveying rods are rotatably arranged. When in use, a steel component is placed on the conveying rods, and the steel component is automatically conveyed. One side of the steel component is against the conveying rods, so that stable conveying can be achieved. When the steel component passes through the shot blasting channel, the surface can be shot blasted and surface treated.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: Taking the I-beam as an example, its bottom surface is always against the conveying rod, and the shot blasting effect received is poor, and position adjustment and multiple shot blasting are often required, so there is room for improvement. Summary of the invention

[0005] In order to improve the shot blasting effect, the present application provides a steel component surface treatment equipment and process.

[0006] In the first aspect, the present application provides a steel component surface treatment device adopting the following technical solution:

[0007] A steel component surface treatment device comprises a shot blasting channel and a conveying frame passing through the shot blasting channel, wherein at least one pair of support frames are arranged on the surface of the conveying frame, a clamping mechanism for fixing the steel component is arranged inside the support frame, and a rotating mechanism for driving the clamping mechanism and the steel component to rotate as a whole is also arranged inside the support frame.

[0008] By adopting the above technical solution, the shot blasting effect on the surface of steel components can be significantly improved. Specifically, by setting up a support frame and a clamping mechanism, it is possible to ensure that the steel components remain stable during transportation and avoid uneven shot blasting caused by position offset. At the same time, the introduction of the rotating mechanism enables the steel components to rotate automatically during transportation, so that all surfaces of the steel components can fully receive shot blasting treatment, solving the problem of poor shot blasting effect on the bottom surface in traditional methods. This not only improves the shot blasting efficiency, but also ensures the quality and consistency of the surface treatment of steel components.

[0009] Preferably, the rotating mechanism includes a movable swivel and a rotating drive, the movable swivel is rotatably connected to the conveying frame, a driving gear is provided on the driving shaft of the rotating drive, the movable swivel is provided with a driving gear ring, and the driving gear is meshed with the driving gear ring.

[0010] By adopting the above technical solution, the setting of the rotating mechanism enables the steel component to rotate automatically during the conveying process, ensuring that the steel component is evenly shot blasted around the circumference, thereby improving the shot blasting effect and efficiency. Specifically, the movable swivel is rotatably connected to the conveying frame, and the driving gear on the rotating drive shaft is meshed with the driving gear ring on the movable swivel. This mechanical transmission method can reliably drive the steel component to rotate, avoiding the problem of uneven shot blasting caused by fixed position in traditional methods.

[0011] Preferably, the clamping mechanism comprises at least one pair of clamping plates and a clamping drive for driving each clamping plate to press against the steel member.

[0012] By adopting the above technical solution, the clamping mechanism can effectively fix the steel component, ensure that it remains stable during transportation and rotation, and avoid loosening or falling off due to vibration or impact, thereby improving the uniformity and efficiency of shot blasting. Specifically, the design of the clamping plate can be adjusted according to the specific size and shape of the steel component, enhancing the adaptability and flexibility of the equipment. The setting of the clamping drive further ensures the controllability and reliability of the clamping force, so that the steel component is always in the best fixed state during the shot blasting process, improving the quality and consistency of the surface treatment.

[0013] Preferably, a sliding seat is provided at the bottom of the clamping mechanism, the movable ring is provided with a slideway, the sliding seat is slidably arranged inside the slideway, and the sliding seat is provided with a locking piece for temporary fixation relative to the slideway.

[0014] By adopting the above technical solution, a slide is set at the bottom of the clamping mechanism and a slideway is set in the movable ring. The slide can slide in the slideway, and the slide is provided with a locking piece, which can be temporarily fixed after sliding. This design allows the position of the clamping mechanism to be flexibly adjusted according to the specific shape and size of the steel component, improving the adaptability and processing effect of the equipment to different types of steel components. Especially when processing steel components with complex shapes, it can ensure that the clamping mechanism is always in the best position, improving the uniformity and efficiency of shot blasting. In addition, the design of the locking piece ensures the stability of the clamping mechanism during operation and avoids processing quality problems caused by position changes.

[0015] Preferably, the locking member comprises a locking bolt, and a plurality of locking holes are formed through the inner wall of the slideway. The locking bolt passes through the locking holes and is tightly pressed against the slide seat.

[0016] By adopting the above technical solution, the locking member includes a locking bolt, and a plurality of locking holes are provided through the inner wall of the slideway. The locking bolt passes through the locking holes and is tightly pressed against the slide seat. This design can ensure that the fixed position of the slide seat in the slideway is more stable, and prevent the slide seat from loosening due to vibration or other factors, thereby ensuring that the clamping mechanism is always in the predetermined position during the conveying process, and improving the clamping and conveying stability of the steel component. At the same time, by selecting different locking holes, the position of the clamping mechanism can be flexibly adjusted to adapt to steel components of different sizes and shapes, thereby enhancing the versatility and scope of application of the equipment.

[0017] Preferably, the clamping plate is further provided with a traveling mechanism, which abuts against the steel member and is used to drive the steel member to move relative to the clamping plate along the conveying direction of the conveying frame.

[0018] By adopting the above technical solution, the walking mechanism on the clamping plate can push the steel component to move along the direction of the conveyor frame, thereby changing the position of the steel component relative to the support frame. This allows the steel component that was originally blocked by the support frame to be exposed and fully shot blasted, thereby improving the uniformity and integrity of the surface treatment of the steel component. At the same time, the setting of the walking mechanism also avoids the need to manually adjust the position of the steel component, improving the processing efficiency and automation.

[0019] Preferably, the walking mechanism includes a plurality of power-assisting rollers and power-assisting belts wound around the outside of the plurality of power-assisting rollers, the power-assisting belts are against the steel structure, the plurality of power-assisting rollers are arranged in the circumference of the clamping plate and the plurality of power-assisting rollers are rotatably connected to the clamping plate, and the clamping plate is provided with a power-assisting driving unit for driving the power-assisting belts to rotate.

[0020] By adopting the above technical solution, the steel components can achieve relative movement within the support frame through the walking mechanism during the transportation process. Specifically, the design of several power-assist rollers and power-assist belts can provide stable support while reducing friction resistance to ensure smooth movement of the steel components. The power-assist drive unit drives the power-assist belt to rotate, further pushing the steel component to move relative to the clamping plate, thereby changing the shielding position of the support frame on the steel component, allowing the originally shielded part of the steel component to be effectively shot blasted, thereby improving the shot blasting efficiency and quality.

[0021] Preferably, the power-assisted driving unit includes a resisting wheel, a rotating shaft, a power-assisted wheel and a power-assisted driving member, the driving end of the clamping drive is provided with a mounting column, the clamping plate is connected to the mounting column, the mounting column is provided with a mounting hole, the power-assisted wheel is rotatably arranged in the mounting hole, the rotating shaft is connected to the power-assisted wheel, the resisting wheel is connected to the end of the rotating shaft, the resisting wheel is resisted against the power-assisted belt, and the power-assisted driving member is used to drive the power-assisted wheel to rotate.

[0022] By adopting the above technical solution, the power-assisting wheel is driven to rotate by the power-assisting driving member, thereby driving the rotating shaft and the two end wheels to rotate, and the wheels abut the power-assisting belt of the clamping plate facing away from the steel component to realize the rotation of the power-assisting belt. At the same time, the wheels can actually abut the power-assisting belt between two adjacent power-assisting rollers, making the power-assisting belt concave, thereby achieving the tension of the power-assisting belt to a certain extent. This not only improves the stability of the steel component during the transportation process, but also reduces the resistance of the power-assisting belt during the turnover process, and improves the overall operation efficiency and reliability of the equipment.

[0023] Preferably, limit plates are further provided on both sides of the clamping plate, and a limit drive is provided between the limit plate and the clamping plate, and the limit drive is used to drive the clamping plate to extend and retract relative to the clamping plate.

[0024] By adopting the above technical solution, limit plates are set on both sides of the clamping plate, and a limit drive is set between the limit plate and the clamping plate, and the limit drive is used to drive the clamping plate to extend and retract relative to the clamping plate. This design can effectively improve the stability of steel components during transportation and rotation, prevent steel components from being offset or falling off due to vibration or impact during shot blasting, and ensure the uniformity and efficiency of shot blasting. At the same time, the telescopic function of the limit plate can be flexibly adjusted according to steel components of different sizes and shapes, further improving the scope of application and operational flexibility of the equipment.

[0025] In the second aspect, the present application provides a steel component surface treatment process, which adopts the following technical solution:

[0026] A surface treatment process for steel components, wherein the steel components are installed in a supporting frame through a clamping mechanism, and the supporting frame is placed on a conveying frame for conveying. During the conveying process, the steel components automatically rotate under the action of a rotating mechanism, thereby achieving shot blasting treatment at various locations around the steel components.

[0027] By adopting the above technical solution, the steel components can be shot blasted in all directions during the transportation process, avoiding the problem of poor local shot blasting effect caused by the fixed position of the steel components in the traditional method. Specifically:

[0028] 1. Rotating mechanism: Through the action of the rotating mechanism, the steel components can automatically rotate during the transportation process, ensuring that the steel components can be evenly shot blasted at all circumferences, thus improving the shot blasting effect and efficiency.

[0029] 2. Clamping mechanism: The clamping mechanism can firmly fix the steel component, ensure the stability of the steel component during rotation, prevent the steel component from shifting or falling off during processing, and improve the safety and reliability of processing.

[0030] 3. Traveling mechanism: The traveling mechanism enables the steel structure to be displaced relative to the supporting frame during transportation, further optimizing the shot blasting effect, ensuring that every part of the steel structure surface can be effectively treated, and reducing the need for repeated shot blasting.

[0034] 3. The combined design of the clamping mechanism and the rotating mechanism not only improves the shot blasting uniformity of the steel components, but also reduces the frequency of manual adjustment of the position of the steel components, greatly improves production efficiency, and reduces processing time and cost.

[0048] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0049] The inventor of the present application has found that the existing shot blasting machine has a poor shot blasting effect when processing steel components such as I-beams because the bottom surface is always against the conveying rod, and the position needs to be adjusted many times, so it needs to be improved. To this end, the present application mainly adopts the following scheme: at least one pair of support frames are provided on the surface of the conveying frame, and a clamping mechanism for fixing the steel component is provided inside the support frame. A rotating mechanism for driving the clamping mechanism and the overall rotation of the steel component is also provided inside the support frame, so as to achieve the purpose of automatically rotating the steel component during the conveying process so that each surface can be evenly shot blasted. The following is a further detailed description of the present application.

[0050] Example

[0051] Reference Figure 1 The surface treatment equipment for steel components provided in the embodiment of the present application includes a shot blasting channel 1 and a conveying frame 11 passing through the shot blasting channel 1. A plurality of conveying rods 12 are evenly distributed in the conveying frame 11 and equipped with a conveying driving member 13 to realize the rotation of the plurality of conveying rods 12. The plurality of conveying rods 12 do not directly contact the steel components, but a pair or more supporting frames 2 are arranged on the surface of the conveying frame 11. The outer contour of the supporting frame 2 is square, so that the bottom of the supporting frame 2 can be stably placed on the conveying frame 11 for stable conveying. The length of the supporting frame 2 can at least span three adjacent conveying rods 12, so as to realize continuous conveying. The steel components pass through each supporting frame 2 and are conveyed as the supporting frame 2 is conveyed on the conveying frame 11.

[0052] Reference Figure 2The support frame 2 is provided with a clamping mechanism 3 for fixing the steel member and a rotating mechanism 4 for driving the clamping mechanism 3 to rotate. Through this design, the automatic rotation of the steel member can be realized during the conveying process, thereby achieving a comprehensive shot blasting effect.

[0053] Specifically, the rotating mechanism 4 includes a movable swivel 41 and a rotating drive 42. The movable swivel 41 is rotatably connected to the inner wall of the conveying frame 11 through a bearing, a driving gear 43 is provided on the driving shaft of the rotating drive 42, and a driving gear ring 44 is integrally formed on the edge of the movable swivel 41, and the driving gear 43 is meshed with the driving gear ring 44. In this way, the rotating drive 42 can drive the movable swivel 41 to rotate through the meshing action of the driving gear 43 and the driving gear ring 44, thereby rotating the clamping mechanism 3 and the steel member as a whole. The rotating drive 42 can use a servo motor with a reducer, and through the precise control of the servo motor, the precise adjustment of the rotation speed of the steel member can be achieved. The reducer can use a planetary reducer or a worm gear reducer, the former is suitable for occasions requiring high precision and high torque, and the latter is suitable for occasions requiring a large reduction ratio. The meshing surfaces of the driving gear 43 and the driving gear ring 44 can be specially treated, such as chrome plating or carburizing, to improve their wear resistance and service life. In addition, a lubrication device, such as oil mist lubrication or grease lubrication, may be provided between the driving gear 43 and the driving gear ring 44 to reduce wear and noise.

[0054] The clamping mechanism 3 includes a pair or more clamping plates 31 and clamping drives 32 for driving each clamping plate 31 to clamp the steel member. In this embodiment, two clamping plates 31 and two clamping drives 32 are provided. The clamping plate 31 can be made of metal material, such as stainless steel or aluminum alloy, to increase its strength and durability. The clamping drive 32 can be a cylinder, a hydraulic cylinder or an electric push rod, and the clamping plate 31 is driven by air pressure, hydraulic pressure or electric energy to clamp the steel member.

[0055] A slide is also provided at the bottom of the clamping mechanism 3, and a slideway is provided inside the movable swivel 41. The slide is adapted to slide inside the slideway. When the steel member is an I-beam with two standard and symmetrical abutting surfaces, the two clamping mechanisms 3 can be symmetrically arranged. When the abutting surfaces of the steel member are asymmetrical and there are multiple ones, the number and position of the clamping mechanisms 3 can be adjusted as needed. Each slide is provided with a corresponding locking member, which is used to temporarily fix the slide relative to the slideway. In this embodiment, the locking member includes a locking bolt, and a plurality of locking holes are provided along the side of the inner wall of the slideway. After the locking bolt passes through the locking hole, it is tightly abutted against the corresponding slide to achieve the locking of the slide. In this way, by adjusting the position of the locking bolt, the precise positioning of the clamping mechanism 3 can be achieved.

[0056] Reference Figure 3 and Figure 4, the driving end of the clamping drive 32 is provided with a mounting column 53, and the clamping plate 31 is actually connected to the clamping drive 32 through the mounting column 53. The clamping plate 31 is also provided with a walking mechanism 5, which is against the steel member and is used to drive the steel member to move relative to the clamping plate 31 along the conveying direction of the conveying frame 11. The walking mechanism 5 includes a plurality of power-assisting rollers 51 and a power-assisting belt 52 wound around the outside of the plurality of power-assisting rollers 51, and the power-assisting belt 52 is used to abut against the steel member to make the steel member have less resistance when "walking" relative to the clamping plate 31. The power-assisting roller 51 can be made of high-hardness plastic or metal material to reduce friction loss and improve wear resistance. The power-assisting belt 52 can be made of high-strength synthetic fiber material to ensure its durability in long-term operation. A plurality of power-assisting rollers 51 are arranged on the circumference of the clamping plate 31 and the plurality of power-assisting rollers 51 are rotatably connected to the clamping plate 31, and in this embodiment, the plurality of power-assisting rollers 51 are arranged in two groups, so that the two groups of power-assisting rollers 51 cooperate with the power-assisting belt 52 to form a crawler-type walking mechanism 5.

[0057] Reference Figure 5 The mounting column 53 is provided with a power-assistance driving unit 6 for driving the power-assistance belt 52 to rotate. The power-assistance driving unit 6 includes a wheel 61, a rotating shaft 62, a power-assistance wheel 63 and a power-assistance driving member 64. The rotating shaft 62 penetrates the mounting column 53 and is rotatably connected to the mounting column 53. A mounting hole 65 is penetrated in the middle of the mounting column 53. The power-assistance wheel 63 is rotatably arranged in the mounting hole 65 through a bearing. The rotating shaft 62 and the power-assistance wheel 63 are fixedly connected. In this embodiment, the wheel 61 is provided with two wheels and is respectively fixedly connected to the ends of the rotating shaft 62. The wheel 61 is abutted against the power-assistance belt 52, and the rotation of the wheel 61 is used to realize the rotation of the power-assistance belt 52. Since the power-assistance belt 52 has a plurality of power-assistance rollers 51 inside, and there is a gap between two adjacent power-assistance rollers 51, the wheel 61 can abut against the section of the power-assistance belt 52 between the two adjacent power-assistance rollers 51 in the actual state of the present application, so that the power-assistance belt 52 at this section is concave, and the tension of the power-assistance belt 52 can be realized to a certain extent. In this embodiment, the power-assist driving member 64 can use a motor in conjunction with a transmission belt to realize the rotation of the power-assist wheel 63, thereby driving the power-assist belt 52 to move, and finally causing the steel component to move relative to the clamping plate 31, namely the support frame 2.

[0058] Reference Figure 2, limit plates 7 are also provided on both sides of the clamping plate 31, and a limit drive 71 is provided between the limit plate 7 and the clamping plate 31. The limit drive 71 is used to drive the clamping plate 31 to extend and retract relative to the clamping plate 31, so as to limit the side when the steel member "walks" relative to the clamping plate 31. The limit plate 7 can be made of high-strength metal materials, such as stainless steel or alloy steel, to enhance its rigidity and impact resistance. The limit drive 71 can use a hydraulic cylinder or an electric push rod to drive the limit plate 7 to extend and retract through hydraulic or electric energy. For example, a hydraulic cylinder is suitable for occasions requiring a large thrust, while an electric push rod is suitable for situations where the telescopic distance needs to be precisely controlled. The connection between the limit plate 7 and the clamping plate 31 can be achieved by pins or screws to ensure the firmness and reliability of the connection.

[0059] The implementation principle of this embodiment is: through the drive of the rotating mechanism 4, the steel member can be continuously rotated during the transportation process, so that each surface of the steel member can be uniformly shot blasted. This design not only improves the shot blasting effect, but also reduces the number of times the position of the steel member is manually adjusted, thereby improving production efficiency. At the same time, the flexible adjustment ability of the clamping mechanism 3 and the design of the walking mechanism 5 make the equipment suitable for steel members of various shapes and lengths, enhancing the versatility and scope of application of the equipment. The design of the limit plate 7 further improves the stability of the steel member during transportation, reduces the risk of derailment of the steel member, and ensures production safety.

[0060] The actual surface treatment process includes the following specific steps:

[0061] S1, install the steel component in the support frame 2 through the clamping mechanism 3, and ensure that the steel component is firmly fixed between the clamping plates 31. The clamping plates 31 can be appropriately adjusted according to the shape of the steel component and fixed at a suitable position on the slideway 34 through the locking member 35.

[0062] S2, placing the support frame 2 on the conveying frame 11, starting the conveying frame 11, and sending the steel structure into the shot blasting channel 1.

[0063] S3, start the rotary drive 42, and the rotary drive 42 drives the movable rotating ring 41 to rotate through the meshing action of the driving gear 43 and the driving gear ring 44, thereby causing the clamping mechanism 3 and the steel component to rotate as a whole.

[0064] S4, when the steel component enters the shot blasting channel 1, the steel component is continuously rotated under the action of the rotating mechanism 4, so that each surface of the steel component can be evenly shot blasted.

[0065] S5, for long or complex-shaped steel components, the walking mechanism 5 can be started to displace the steel component relative to the support frame 2 along the conveying direction of the conveyor frame 11, thereby avoiding the continuous blocking of a single part of the steel component by the support frame 2 and ensuring the uniformity and thoroughness of the shot blasting effect.

[0066] S6, after the shot blasting is completed, the rotary drive 42 and the travel mechanism 5 are stopped, the steel member is taken out from the support frame 2, and the shot blasting effect is checked.

[0067] The implementation principle of this embodiment is: through the above process steps, the automatic rotation and displacement of the steel component during the transportation process can be achieved, thereby ensuring that all surfaces of the steel component can be uniformly shot blasted. This process not only improves the shot blasting effect, but also simplifies the operation process, reduces manual intervention, and improves production efficiency.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
