Description

Technical Field

[0001] This utility model relates to the technical field of polishing devices, specifically to a polishing device for a single-piece heating element. Background Technology

[0002] In the manufacturing process of heating equipment, the quality of the radiator fins, as a key component, directly affects the overall performance and usability of the heating equipment. The grinding process is a crucial step in radiator fin production. Grinding removes burrs and uneven parts from the ends of the radiator fins, ensuring surface smoothness and dimensional accuracy, thereby guaranteeing the assembly sealing and connection stability between radiator fins.

[0003] Currently, existing grinding devices for radiator fins generally suffer from poor fin securing during grinding. Due to the lack of effective positioning and clamping structures, radiator fins are prone to shifting during the grinding process. Once a radiator fin shifts, the grinding equipment cannot accurately grind its ends, resulting in uneven ends after grinding. Uneven ends of radiator fins, when assembled into a heating system, not only affect the appearance of the system but may also cause poor sealing at joints, leading to leaks, reducing heating efficiency and lifespan, increasing maintenance costs, and posing safety hazards. Therefore, there is an urgent need to design a grinding device that can effectively prevent radiator fin shifting during grinding and ensure flat ends after grinding. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a grinding device for heating radiator single-piece accessories, which solves the technical problem in the prior art that the heating radiator single-piece offset during the grinding process causes unevenness at the end of the grinding radiator single-piece.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-9 As shown, this invention illustrates a grinding device for single-piece heating element accessories in one embodiment, comprising a frame 1, a base 2, a conveyor 3, a grinding mechanism 5, and a limiting frame 6. The frame 1 is horizontally placed to support the base 2. The base 2 is a square plate and there are two bases, both of which can slide horizontally on the frame 1 to adjust the distance between them. The conveyor 3 is disposed on the base 2 and vertically arranged above the frame 1. The top of the conveyor 3 has a conveying plane 31, the surface of which is smooth, effectively avoiding the problem of the outer peripheral wall becoming rough due to friction with the outer peripheral wall of the single-piece heating element 4 during the conveying process. The conveying plane 31 is used to place the single-piece heating element 4, and the single-piece heating element 4 can slide along the conveying plane 31, allowing the single-piece heating element 4 to run to the grinding area of ​​the grinding mechanism 5 for grinding. Generally, the conveying work can be completed by manual pushing by the operator, or by using a screw motor or cylinder drive, etc.

[0026] There are two grinding mechanisms 5, each mounted on a base 2, and each grinding mechanism 5 can slide along the base 2 to accommodate single-piece straight heating pipes 4 of different sizes. Furthermore, each grinding mechanism 5 is equipped with two parallel grinding belts 51, arranged sequentially along the running direction of the conveyor 3. The first set of grinding belts 51 near the starting end of the conveyor 3 performs preliminary grinding on the end of the single-piece straight heating pipe 4. When the single-piece straight heating pipe 4 moves to the second set of grinding belts 51, the grinding belts 51 perform fine grinding on its end again to ensure the flatness of the end of the single-piece straight heating pipe 4, effectively reducing end burrs and facilitating subsequent welding operations.

[0027] The grinding belts 51 on the two grinding mechanisms 5 are arranged opposite each other to ensure that the two grinding belts 51 on the two grinding mechanisms 5 can grind both ends of the single straight pipe 4 of the heating system at the same time, which solves the problem that some existing equipment needs to grind one end at a time, thereby improving work efficiency; there are two limit frames 6, and each limit frame 6 is set on a base 2, and the length is the same as that of the grinding mechanism 5, so that each single straight pipe 4 of the heating system that reaches the width area of ​​the grinding mechanism 5 can be limited.

[0028] Specifically, the limiting frame 6 is positioned above the single-piece straight pipe 4 of the heating system and is set as a suspended frame. The suspended frame can prevent the limiting frame 6 from scratching the outer wall of the single-piece straight pipe 4 due to its rough surface. Several pressure rods 61 are set on the suspended frame. The pressure rods 61 are used to press the single-piece straight pipe 4 of the heating system. The several pressure rods 61 are arranged at intervals to ensure that each single-piece straight pipe 4 of the heating system that reaches the grinding area can be pressed, preventing the single-piece straight pipe 4 of the heating system from deviating from its position during the grinding operation along with the grinding belt 51, thereby improving the flatness of the end of the single-piece straight pipe 4 of the heating system. In addition, the pressure rods 61 are hinged to the suspended frame through a rotating shaft. When the single-piece straight pipe 4 of the heating system is running, it can swing vertically in the running direction so that the single-piece straight pipe 4 of the heating system can be ground continuously.

[0029] It should be noted that a torsion spring is provided at the hinge point between the pressure rod 61 and the rotating shaft, or a hydraulic push rod or electric push rod is provided at the movable end of the pressure rod 61, so that the pressure rod 61 can automatically press the single straight pipe 4 of the heating system during the grinding work.

[0030] For example, such as Figure 4As shown, the conveying component 3 includes a side plate 32, a circulating chain 33, and push rods 34. There are two side plates 32, each of which is mounted on a base 2. The two side plates 32 are arranged opposite to each other. The side plates 32 are used to install the circulating chain 33 and support the conveying plane 31. Specifically, in some examples, the circulating chain 33 is mounted on the side plate 32 and is driven to circulate by sprocket engagement. Push rods 34 are installed on the chain links. The circulating chain 33 is used to convey the single-piece straight heating pipe 4 at a low speed but with a strong load-bearing capacity. The push rods 34 are L-shaped and there are several of them. The push rods 34 are spaced apart on the circulating chain 33 and are used to push the single-piece straight heating pipe 4 to slide along the conveying plane 31. The vertical arm of the push rod 34 abuts against the single-piece straight heating pipe 4, and the horizontal arm is fixed to the circulating chain 33 to ensure that the single-piece straight heating pipe 4 will not fall off or shift during the grinding process. It should be noted that the conveyor 3 can slide on the frame 1 along with the base 2, thereby realizing flexible adjustment of the width of the conveyor 3 to adapt to heating single-piece straight pipes 4 of different lengths.

[0031] For example, such as Figure 7 As shown, it should be noted that the simultaneous action of the pressure rod 61 above the heating radiator straight pipe 4 and the push rod 34 on the circulating chain 33 effectively prevents the heating radiator straight pipe 4 from shifting or falling off during the polishing process.

[0032] For example, such as Figure 5 As shown, in some examples, the device also includes: a limiting rod 62 and a pin 63. There are several limiting rods 62, which are arranged at intervals and hinged on the limiting frame 6, and vertically penetrate the gap between the single-piece straight pipes 4 of the heating system, for further fixing the single-piece straight pipes 4 of the heating system.

[0033] Specifically, when the heating radiator straight pipe 4 pushes the limiting rod 62, the limiting rod 62 has a large weight, and the heating radiator straight pipe 4 can press against the push rod 34 under the weight of the limiting rod 62. This prevents the heating radiator straight pipe 4 from entering the grinding operation area after being transported, and avoids the problem of the heating radiator straight pipe 4 detaching from the push rod 34 or the push rod 34 loosening its fixing of the heating radiator straight pipe 4. This ensures that the heating radiator straight pipe 4 will not deviate during grinding. There are several pins 63, and all of the pins 63 are set on the limiting frame 6. Each pin 63 corresponds to a limiting rod 62. The pins 63 are used to limit the limiting rod 62, ensuring that the range of motion of the limiting rod 62 is effectively restricted.

[0034] To further explain, the limiting rod 62 rotates on the suspended frame via a rotating shaft. The heating single-piece straight pipe 4 is driven by the circulating chain 33 to push the limiting rod 62 to rotate. After the heating single-piece straight pipe 4 passes the limiting rod 62, the limiting rod 62 swings back. When it swings back to the vertical direction, the pin 63 limits the excessive swing of the limiting rod 62, preventing it from hitting the outer peripheral wall of the next heating single-piece straight pipe 4 being transported. This effectively avoids the problem of the grinding belt 51 grinding the ends of the two heating single-piece straight pipes 4, thereby improving the accuracy of grinding.

[0035] It should be noted that the limiting rod 62 and the pressure rod 61 are respectively arranged on the front and rear sides of the suspension frame, so that the heating single-piece straight pipe 4 is precisely fixed, so that the heating single-piece straight pipe 4 will not shift during the grinding process, improving the flatness of the heating single-piece straight pipe 4, and thus improving the yield of the heating single-piece straight pipe 4 in the subsequent welding work.

[0036] For example, such as Figure 5 As shown, specifically, the pressure rod 61 is L-shaped, with the vertical rod located on the suspended frame and the horizontal rod abutting against the outer peripheral wall of the single-piece straight pipe 4 of the heating system. This prevents the single-piece straight pipe 4 of the heating system from moving up and down under the force of the grinding belt 51 during the grinding process, effectively ensuring the flatness of the single-piece straight pipe 4 of the heating system during grinding. The inflection point of the pressure rod 61 is hinged to the limiting frame 6, and the outer peripheral wall of the inflection point of the pressure rod 61 is arc-shaped, which can prevent the sharp edges at the inflection point from scratching the outer peripheral wall of the single-piece straight pipe 4 of the heating system.

[0037] In addition, rollers 64 are provided at the ends of the pressure rod 61 and the limiting rod 62 that contact the heating single-piece straight pipe 4. These rollers 64 roll in contact with the outer peripheral wall of the heating single-piece straight pipe 4. When the conveying plane 31 is running, the contact mode between the ends of the pressure rod 61 and the limiting rod 62 and the outer peripheral wall of the heating single-piece straight pipe 4 changes from sliding friction to rolling friction, thereby effectively avoiding the problem of scratching the outer peripheral wall of the heating single-piece straight pipe 4.

[0038] For example, such as Figure 9 As shown, a slag cleaning mechanism 7 is provided at the bottom of the frame 1. The slag cleaning mechanism 7 includes a slag collection bin 71 and an air extraction pipe 72. The slag collection bin 71 is located on the base 2 and directly below the end of the single straight pipe 4 of the heating element that is being ground by the grinding belt 51. The overall shape is funnel-shaped, which facilitates the collection of falling slag. The air extraction pipe 72 is located at the slag outlet 701 of the slag collection bin 71. Specifically, the air extraction pipe 72 and the slag outlet 701 are connected. The slag is sucked out of the slag collection bin 71 by negative pressure suction, which plays a role in timely discharge of slag and prevents excessive slag from accumulating in the slag collection bin 71. Excessive slag overflow will reduce the grinding efficiency.

[0039] For example, such as Figure 3As shown, in some examples, the grinding mechanism 5 also includes a mounting frame 52, a drive motor 53, a drive roller 54, and a driven roller 55. Specifically, the mounting frame 52 is mounted on the base 2; the drive motor 53 is mounted on the mounting frame 52; the drive roller 54 is mounted on the power output end of the drive motor 53; the driven roller 55 is rotatably mounted on the mounting frame 52; and the grinding belt 51 is sequentially wound around the drive roller 54 and the driven roller 55. The drive motor 53 drives the drive roller 54, thereby driving the driven roller 55 to run, so that the grinding belt 51 performs the grinding work. It should be noted that the working method of the grinding mechanism 5 used in this application is the same as that of a traditional grinding device, and will not be described in detail here.

[0040] For example, such as Figure 2 As shown, the grinding mechanism 5 also includes a telescopic rod 56 and a pressure plate 57. Specifically, the telescopic rod 56 is mounted on the mounting bracket 52; the pressure plate 57 is mounted on the movable end of the telescopic rod 56. The telescopic rod 56 can push or retract the pressure plate 57 towards the end of the single-piece straight pipe 4 of the heating system, so as to ensure that the grinding belt 51 can evenly and effectively contact the end of the single-piece straight pipe of the heating system during operation, so that the flatness of the single-piece straight pipe 4 of the heating system after grinding is higher, thereby achieving the best grinding effect. When the single-piece straight pipe 4 of the heating system has not yet reached the position directly opposite the grinding belt 51, the telescopic rod 56 can drive the pressure plate 57 to retract, so that the single-piece straight pipe 4 of the heating system can smoothly enter the working area of ​​the grinding belt 51.

[0041] In some examples, the grinding mechanism 5 also includes a tensioning element 58, which is spring-tensioned and mounted on the mounting bracket 52. Specifically, when installing the grinding belt 51, the spring is adjusted so that the tensioning element 58 presses against the grinding belt 51 to form initial tension. The elastic force of the spring is evenly applied to the grinding belt 51 through the tensioning element 58, keeping it taut. When the grinding belt 51 loosens due to wear, temperature changes, or operational vibration, the spring automatically releases its elastic force, pushing the tensioning element 58 to finely adjust its position and maintain the tension of the grinding belt 51, ensuring that the grinding belt 51 remains taut at all times during operation.

[0042] For example, such as Figure 1 As shown, a slide rail 101 is provided on the frame 1 to facilitate the sliding of the base 2 on the frame 1, thereby facilitating the adjustment of the position of the grinding mechanism 5 and the conveying component 3. This allows the device to adapt to different sizes of single-piece straight heating pipes 4, making the device more widely applicable; and it also facilitates the later maintenance of the entire grinding device.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
