Description

Technical Field

[0001] This application relates to the technical field of stainless steel pipe processing, and in particular to a stainless steel pipe inner wall polishing device. Background Technology

[0002] In the vast field of stainless steel product processing, stainless steel pipes, with their superior corrosion resistance and elegant appearance, have become an indispensable element in many industries such as construction, chemical, and food. However, to maintain the high smoothness and continuous corrosion resistance of the pipe's inner wall, the polishing process plays a crucial role. This not only affects the final quality of the product but also directly impacts its performance and lifespan in various application scenarios.

[0003] Currently, a common type of stainless steel pipe inner wall polishing machine on the market features an ingenious design, integrating core components such as a base, polishing assembly, and clamping assembly. The polishing assembly achieves fine polishing of the steel pipe's inner wall through the coordinated action of the polishing wheel and drive motor, as well as precise control of the motor's lead screw structure. Meanwhile, the clamping assembly utilizes a clever combination of clamping wheels, cylinders, and support wheels to ensure stable clamping and precise positioning during the polishing process.

[0004] However, in practice, a significant technical bottleneck has gradually emerged: at the initial stage of polishing, namely the feeding of steel pipes, it is often necessary to manually move the heavy steel pipes and precisely place them on the support wheels. This process is not only time-consuming and labor-intensive, significantly slowing down the overall polishing efficiency, but has also become a key factor restricting the capacity for large-scale processing. Faced with increasing market demand and ever-improving production standards, the existing manual feeding method is clearly unable to meet the requirements of efficient and automated production, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a stainless steel pipe inner wall polishing device to solve the problem that the above-mentioned polishing machine has low efficiency during feeding and cannot meet the needs of large-scale processing.

[0006] The stainless steel pipe inner wall polishing equipment provided in this application adopts the following technical solution: A stainless steel pipe inner wall polishing device includes a base, a clamping assembly, and a polishing assembly. The polishing assembly includes a support plate slidably mounted on the base, a first motor fixed on the support plate, a polishing wheel coaxially fixed with the output shaft of the first motor, and a power component for driving the support plate to slide. The clamping assembly includes a clamping wheel located above the base and a third driving component for driving the clamping wheel to move up and down. The base is provided with a first support wheel and a second support wheel located below the clamping wheel. A bracket is provided on the side of the base, and a feeding slide inclined downwards along the direction close to the base is fixed on the bracket. The steel pipe on the feeding slide can slide between the first support wheel and the second support wheel. A first baffle and a second baffle are arranged side by side above the feeding slide, and a gap is preset between the first baffle and the second baffle to limit the movement of a single steel pipe. A first power source and a second power source are fixed on the bracket to drive the first baffle and the second baffle to move up and down, respectively.

[0007] By adopting the above technical solution, the steel pipes on the feeding chute can slide one by one into the position between the first support wheel and the second support wheel during the feeding process through the combination of the first baffle and the second baffle, thereby realizing the automatic feeding of stainless steel pipes, improving the overall polishing efficiency of stainless steel pipes, and enabling the polishing equipment to meet the needs of mass production.

[0008] Optionally, a receiving plate is provided on the base, and a first driving component and a second driving component are fixed on the receiving plate to drive the first support wheel and the second support wheel to move up and down respectively.

[0009] By adopting the above technical solution, the installation height of the first support wheel and the second support wheel can be adjusted due to the combination of the first driving component and the second driving component, making it easier for the stainless steel pipe on the feeding slide to slide between the first support wheel and the second support wheel.

[0010] Optionally, a support arm is fixedly provided on the receiving plate in the vertical direction, and a support plate located above the first support wheel and the second support wheel is fixedly provided at the upper end of the support arm. The third driving component is a vertical cylinder fixed on the support plate, and the lower end of the vertical cylinder passes through the support plate and is fixedly connected to the clamping wheel.

[0011] By adopting the above technical solution, the height adjustment of the clamping wheel is realized due to the combination of the support arm and the vertical cylinder, which facilitates the clamping wheel to clamp the steel pipe between the first support wheel and the second support wheel.

[0012] Optionally, the receiving plate is slidably disposed on the upper surface of the base, and the sliding direction of the receiving plate is perpendicular to that of the support plate. A drive electric cylinder is fixed on the base to drive the receiving plate to slide back and forth towards the support.

[0013] By adopting the above technical solution, the horizontal installation position of the receiving plate can be adjusted. When feeding is required, the clamping assembly can be driven by the electric cylinder to slide towards the feeding slide, which facilitates the feeding of stainless steel pipes.

[0014] Optionally, a guide rail is fixedly provided on the base, and a guide groove is provided on the bottom side of the receiving plate for the guide rail to be inserted and slid.

[0015] By adopting the above technical solution, during the sliding process of the receiving plate relative to the upper surface of the base, due to the combination of guide rail and guide groove, the guide rail on the base slides into the guide groove on the receiving plate, which improves the stability of the receiving plate during the sliding process.

[0016] Optionally, the support is fixed with a discharge slide located below the feeding slide, and the discharge slide is inclined downward in a direction away from the base.

[0017] By adopting the above technical solution, after the stainless steel pipe is polished, the relative height of the first support wheel and the second support wheel can be adjusted by the first driving component and the second driving component due to the installation of the unloading slide, so that the polished stainless steel pipe slides into the unloading slide, realizing the automatic unloading of the stainless steel pipe and improving the overall processing efficiency of the stainless steel pipe.

[0018] Optionally, the base is provided with a chip removal assembly, which includes a chip removal wheel located above the base and a second motor fixed on the upper surface of the support plate. The second motor is coaxially and fixedly connected to the chip removal wheel. The feeding slide is provided with a limiting assembly for clamping a single steel pipe during feeding. When the polishing wheel is inserted into the clamped steel pipe, the chip removal wheel is simultaneously inserted into the steel pipe in the clamped state on the feeding slide.

[0019] By adopting the above technical solution, when the stainless steel pipe is clamped and the previously polished steel pipe is also clamped by the limiting component on the feeding slide, the chip removal wheel can be inserted into the steel pipe that is clamped on the feeding slide, and the polishing wheel can also be inserted into the steel pipe to be polished at the same time. In this way, the steel pipe can be polished and chip removed at the same time, reducing the time required for subsequent chip removal of the stainless steel pipe and further improving the overall processing efficiency of the stainless steel pipe.

[0020] Optionally, the limiting component includes a first baffle plate and a second baffle plate arranged side by side below the unloading slide. A first driving source and a second driving source are fixed on the bracket to drive the first baffle plate and the second baffle plate to move up and down. The unloading slide has a first blocking hole and a second blocking hole through which the first baffle plate and the second baffle plate pass. The bottom side of the loading slide has a limiting through hole through which a second baffle plate passes. The lower side of the second baffle plate passing through the limiting through hole can abut against the upper side of the steel pipe between the first baffle plate and the second baffle plate.

[0021] By adopting the above technical solution, when the polished steel pipe is placed on the unloading slide and limited by the first and second baffles, the lower side of the second baffle through the limiting through hole can be pressed against the upper side of the steel pipe between the first and second baffles; this realizes the automatic feeding and unloading of steel pipes one by one, and also clamps and limits the steel pipes on the unloading slide at the same time, which facilitates the subsequent chip removal process.

[0022] Optionally, an elastic abutment pad is fixed on the side of the second baffle near the material feeding chute, and the elastic abutment pad is provided with anti-slip texture.

[0023] By adopting the above technical solution, when the lower side of the second baffle is pressed against the upper side of the steel pipe between the first and second baffles, the stability of the lower side edge of the second baffle against the stainless steel pipe is improved due to the setting of the elastic abutment pad on the lower side of the second baffle.

[0024] Optionally, guide slopes are provided on the side edges of the first and second barrier plates, and guide slopes are provided on the opening edge of the limiting through hole.

[0025] By adopting the above technical solution, it is convenient for the first and second barrier plates to be inserted into the corresponding first and second barrier holes, and it is also convenient for the second baffle to be inserted into the limiting through hole, thereby improving the corresponding performance.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During the feeding process, the steel pipes on the feeding chute can slide one by one into the position between the first support wheel and the second support wheel through the combination of the first baffle and the second baffle, so as to realize the automatic feeding of stainless steel pipes, thereby improving the overall polishing efficiency of stainless steel pipes and enabling the polishing equipment to meet the needs of mass production.

The clamping assembly 2 includes a clamping wheel 21 located above the base 1 and a third driving member 22 for driving the clamping wheel 21 to move up and down. The base 1 is provided with a first support wheel 23 and a second support wheel 24 located below the clamping wheel 21. When the polishing equipment is used, the stainless steel pipe is placed on the first support wheel 23 and the second support wheel 24 in advance, and then the clamping wheel 21 is moved down by the third power component 33 to clamp the placed steel pipe. Finally, the polishing component 3 is used for processing.

[0032] Reference Figure 2 and Figure 3 The base 1 is also provided with a sliding support plate 25, and the sliding direction of the support plate 25 is perpendicular to that of the support plate 31. The base 1 is fixed with a drive cylinder 28 that drives the support plate 25 to slide back and forth. The support plate 25 is fixed with a first drive member 26 and a second drive member 27 that respectively drive the first support wheel 23 and the second support wheel 24 to move up and down.

The feeding component 5 is fixed to the feeding slide 51 on the support frame, and the feeding slide 51 is inclined downward along the direction close to the base 1. The steel pipe on the feeding slide 51 can slide between the first support wheel 23 and the second support wheel 24. A first baffle 52 and a second baffle 53 are arranged side by side above the feeding slide 51. The second baffle 53 is located on the side of the first baffle 52 away from the base 1. A gap is preset between the first baffle 52 and the second baffle 53 to limit the movement of a single steel pipe. The bracket 4 is fixed with a first power source 54 and a second power source 55, which respectively drive the first baffle 52 and the second baffle 53 to move up and down. The first power source 54 and the second power source 55 are also located above the feeding slide 51. The first power source 54 and the second power source 55 are conventional electric cylinders, which will not be described in detail here. When the stainless steel tube is fed, the first baffle 52 is moved down to abut against the upper surface of the feeding slide 51 in advance. The second baffle 53 still has a gap with the upper surface of the feeding slide 51. Several stainless steel tubes are placed on the feeding slide 51. At this time, the stainless steel tube at the bottom can slide down to abut against the side of the first baffle 52 near the second baffle 53. Then the second baffle 53 is moved down to abut against the upper surface of the feeding slide 51. Next, control the receiving plate 25 to slide towards the feeding slide 51, then raise the height of the first support wheel 23 and the second support wheel 24, and then move the first baffle 52 upward so that the lowest stainless steel tube slides to the upper side of the first support wheel 23 and the second support wheel 24; adjust the position of the clamped stainless steel tube so that it is coaxial with the polishing wheel 34; then, first move the first baffle 52 downward, then move the second baffle 53 upward so that the stainless steel tube is re-fed, and finally move the second baffle 53 downward again, and repeat this cycle to form the automatic feeding process of the stainless steel tube.

[0034] Reference Figure 5 and Figure 6 The unloading assembly 6 includes an unloading slide 61 fixed on the bracket 4 and a collection box 62 located below the lower end of the unloading slide 61. The unloading slide 61 is located below the loading slide 51 and is inclined downward in a direction away from the base 1. After the stainless steel tube is polished, the relative height of the first support wheel 23 and the second support wheel 24 can be adjusted so that the clamped stainless steel tube slides into the unloading slide 61 to achieve automatic unloading.

[0035] Reference Figure 6 and Figure 7The base 1 is provided with a chip removal assembly 7, which includes a chip removal wheel 71 located above the base 1 and a second motor 72 fixed on the upper surface of the support plate 31, and the output shaft of the second motor 72 is coaxially and fixedly connected to the chip removal wheel 71; the unloading slide 61 is provided with a limiting assembly 8 for clamping a single steel pipe when unloading; the outer periphery of the chip removal wheel 71 is covered with cotton yarn, which can effectively remove chips from the inner wall of the steel pipe after polishing. When the stainless steel pipe is clamped and the previously polished steel pipe is clamped by the limiting component 8 on the unloading slide 61, the chip removal wheel 71 can be inserted into the steel pipe that is clamped on the unloading slide 61, and the polishing wheel 34 can also be inserted into the steel pipe to be polished at the same time, so that the steel pipe can be polished and chip removed at the same time.

[0036] Reference Figure 7 The limiting component 8 includes a first baffle plate 81 and a second baffle plate 82 located below the unloading slide 61. The bracket 4 is fixed with a first driving source 83 and a second driving source 84 that drive the first baffle plate 81 and the second baffle plate 82 to move up and down. The first driving source 83 and the second driving source 84 are cylinders located below the unloading slide 61 and arranged in a vertical direction, which will not be described in detail here. The unloading slide 61 has a first blocking hole 611 and a second blocking hole 612 through which the first baffle plate 81 and the second baffle plate 82 pass. The bottom side of the loading slide 51 has a limiting through hole 511 through which the second baffle plate 53 passes. When the polished steel pipe is placed on the unloading slide 61 and limited by the first baffle plate 81 and the second baffle plate 82, the lower side of the second baffle plate 53 passing through the limiting through hole 511 can abut against the upper side of the steel pipe between the first baffle plate 81 and the second baffle plate 82, thereby limiting the steel pipe on the unloading slide 61 and facilitating subsequent chip removal.

[0037] Reference Figure 7 and Figure 8 The second baffle 53 is fixed with a rubber elastic abutment pad 531 on the side near the unloading slide 61, and the elastic abutment pad 531 is formed with anti-slip texture; to improve the stability of the lower side edge of the second baffle 53 when it abuts against the stainless steel pipe. The first barrier plate 81 and the second barrier plate 82 are provided with guide slopes 811 on their side edges, and the opening edge of the limiting through hole 511 is provided with guide slopes 5111; this facilitates the insertion of the first barrier plate 81 and the second barrier plate 82 into the corresponding first barrier hole 611 and the second barrier hole 612, and also facilitates the insertion of the second baffle 53 into the limiting through hole 511.

[0038] The implementation principle of this application embodiment is as follows: When the polishing equipment is used, the steel pipe on the feeding slide 51 slides into the first support wheel 23 and the second support wheel 24, and then the clamping wheel 21 is driven to move down by the third power component 33, thereby clamping the placed steel pipe and adjusting the position of the clamped stainless steel pipe so that it is coaxial with the polishing wheel 34, and then processing is carried out using the polishing component 3. After the stainless steel pipe is polished, adjust the position of the receiving plate 25 and simultaneously adjust the relative height of the first support wheel 23 and the second support wheel 24 so that the clamped stainless steel pipe can slide into the unloading slide 61, and then use the limiting component 8 to clamp the polished steel pipe. When the next stainless steel pipe is clamped and the previous polished steel pipe is clamped by the limiting component 8 on the feeding slide 61, the chip removal wheel 71 can be inserted into the steel pipe that is clamped on the feeding slide 61, and the polishing wheel 34 can also be inserted into the steel pipe to be polished at the same time, so that the steel pipe can be polished and chip removed at the same time. After chip removal is completed, the steel pipe continues to slide down along the feeding slide 61 into the collection box 62, and this cycle is repeated.
