Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to a novel steel processing polishing machine and polishing method. Background Technology

[0002] New-type steel refers to steel materials that have undergone revolutionary improvements over traditional steel in one or more aspects, such as strength, toughness, lightweight, corrosion resistance, high temperature resistance, and functionality, obtained through innovative alloy design and advanced smelting and processing technologies. Polishing is an unavoidable step in the processing of new-type steel. Belt polishing machines are one commonly used polishing equipment. However, when polishing different types of new-type steel or requiring different polishing grits, belt polishing machines require frequent belt changes, which is inconvenient. This frequent belt changes significantly reduce work efficiency, especially when a single workpiece needs to be polished to different grits.

[0003] Chinese patent CN219485261U discloses a grinding mechanism for a leather head grinding machine. By setting up a grinding belt for transmission and a dust collection structure, the leather head is fixed above the grinding belt by the grippers and rubbed against the surface of the grinding belt to achieve grinding of the leather head surface. This results in a high degree of mechanization, uniform grinding force, and high grinding quality. The dust generated after grinding is removed by the dust collection structure to avoid dust pollution.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the grinding belt needs to be changed to adapt to different grinding and polishing needs, which will greatly reduce work efficiency in situations where the grinding and polishing specifications change frequently. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art that the grinding and polishing belts need to be frequently replaced according to the grinding specifications, and to propose a new type of steel processing polishing machine and polishing method.

[0006] On one hand, this invention proposes a novel steel processing and polishing machine, including a frame, a drive wheel and multiple guide wheels rotatably mounted on the frame, and a motor mounted on the frame to drive the drive wheel to rotate. The drive wheel and multiple guide wheels are connected by a grinding and polishing belt. Multiple grinding and polishing belts are arranged side by side along the length of the guide wheels and the drive wheel, and the multiple grinding and polishing belts have different grinding grits. Multiple tensioning mechanisms are set on the frame, and each tensioning mechanism tensions one grinding and polishing belt from the inside. A lifting frame a is slidably mounted on the frame, and the sliding direction includes the vertical direction and the front-back direction. Two downward pressure rollers are rotatably mounted at the bottom of the lifting frame a. According to the required grinding and polishing grit, the lifting frame a is moved back and forth and then moved downward, so that the two downward pressure rollers press the corresponding grinding and polishing belt downward. The part of the grinding and polishing belt located between the two downward pressure rollers is offset from other grinding and polishing belts.

[0007] Preferably, the tensioning mechanism includes a cylinder mounted on a frame, a rod inserted into the cylinder at one end, a U-shaped frame a mounted at the other end of the rod, a tensioning wheel rotatably mounted on the U-shaped frame a, and a spring sleeved on the cylinder and the rod, with both ends of the spring connected to the U-shaped frame a and the cylinder respectively, and the tensioning wheel abutting against the polishing belt from the inside.

[0008] Preferably, a vertical plate is provided on the frame, and a strip groove is provided on the lifting frame a. The vertical plate passes through the strip groove, and the front-to-back length of the strip groove is greater than the front-to-back length of the vertical plate.

[0009] Preferably, a U-shaped plate is provided at the front end of the lifting frame a, with the U-shaped groove opening on the U-shaped plate facing downwards, and U-shaped frames b are provided at both ends of the bottom of the U-shaped plate, with the pressure rollers rotating on the U-shaped frames b.

[0010] Preferably, it also includes a lifting frame b and a telescopic device a horizontally arranged on the lifting frame b, the telescopic device a being arranged in the front-back direction, and the telescopic end of the telescopic device a being connected to the lifting frame a.

[0011] Preferably, a mounting frame is provided on the frame, and a telescopic device b is vertically installed on the mounting frame. The top of the telescopic end of the telescopic device b is connected to the lifting frame b.

[0012] On the other hand, the present invention proposes a polishing method for a novel steel processing polishing machine, comprising the following steps: S1. The telescopic device b retracts, causing the lifting frame a to move downwards. Two downward pressure rollers press down on a polishing belt, which moves downwards and is offset from other polishing belts. S2. When it is necessary to change the grit size, the lifting frame a should first move upward, and then move back and forth to the position of the required grinding and polishing zone. S3. The telescopic device b retracts, causing the lifting frame a to move downward. The two pressure rollers press down on the polishing belt, moving it downward to a position that is offset from other polishing belts, thus completing the switching of polishing belts with different grit sizes.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: by changing the position of the lifting frame a, different polishing belts can be pressed down, thereby using polishing belts of the required grit. When switching between different polishing belts, the tensioning wheel can always keep the polishing belt taut, ensuring that the polishing belt can complete the polishing work smoothly. There is no need to manually remove the polishing belt and reinstall other polishing belts, making it more convenient to use and improving work efficiency. Attached Figure Description

Detailed Implementation

[0015] Example 1; as Figure 1 As shown, this invention proposes a novel steel processing and polishing machine, comprising a frame 1, a drive wheel 3 and multiple guide wheels 4 rotatably mounted on the frame 1, and a motor 2 mounted on the frame 1 to drive the drive wheel 3 to rotate. The drive wheel 3 and the multiple guide wheels 4 are connected by a polishing belt 5. Specifically, a pulley is mounted on the output shaft of the drive wheel 3 on the frame 1, and a pulley is also mounted on the output shaft of the motor 2. The two pulleys are connected by a belt drive. In this embodiment, three guide wheels 4 are provided. The horizontal section at the bottom of the polishing belt 5 is the polishing working section. The new steel is placed against the outside of the polishing belt 5 to perform polishing work. The motor 2 drives the polishing belt 5 to rotate. This part is existing technology, and there are many such polishing devices on the market, so it will not be described in detail here. Multiple polishing belts 5 are arranged side by side along the length direction of the guide wheels 4 and the drive wheel 3. The multiple polishing belts 5 have different grit sizes. Multiple tensioning mechanisms are provided on the frame 1, and each tensioning mechanism performs polishing work on one of the polishing belts from the inside. The belt 5 is tensioned. A lifting frame a12 is slidably mounted on the frame 1, with sliding directions including vertical and forward / backward directions. Two downward pressure rollers 20 are rotatably mounted at the bottom of the lifting frame a12. Depending on the required polishing grit, the lifting frame a12 is moved forward / backward and then downward, causing the two downward pressure rollers 20 to press down the corresponding polishing belt 5. The portion of the polishing belt 5 located between the two downward pressure rollers 20 is offset from other polishing belts 5, thus facilitating the use of the polishing belt 5. Different polishing belts 5 can be selected for polishing by adjusting the position of the lifting frame a12 as needed, eliminating the need for frequent replacement of the polishing belt 5 and greatly improving efficiency. The tensioning mechanism can continue to tension the polishing belt 5 after the downward pressure rollers 20 press down, ensuring the reliability of the work. It should be noted that only two polishing belts 5 are shown in the attached drawings of this application. In reality, there may be more than two. The number of tensioning mechanisms should correspond to the number of polishing belts 5.

[0016] Example 2; as Figure 3As shown, this invention proposes a novel steel processing and polishing machine. Compared to Embodiment 1, this embodiment details the structure of the tensioning mechanism. The tensioning mechanism includes a cylinder 8 mounted on a frame 1, a rod 9 inserted into the cylinder 8 at one end, a U-shaped frame a10 mounted at the other end of the rod 9, a tensioning wheel 6 rotatably mounted on the U-shaped frame a10, and a spring 11 sleeved on the cylinder 8 and the rod 9. The two ends of the spring 11 are respectively connected to the U-shaped frame a10 and the cylinder 8. The tensioning wheel 6 abuts against the grinding and polishing mechanism from the inside. Specifically, the end of the cylinder 8 is provided with a connecting flange, and the spring 11 is connected to the connecting flange. The frame 1 is provided with a support plate 7, and the connecting flanges on multiple sets of cylinders 8 are all provided on the support plate 7. When the pressure roller 20 presses down on a certain grinding and polishing belt 5, the tensioning roller 6 is pressed, and the insertion rod 9 continues to be inserted into the cylinder 8 to further compress the spring 11. While ensuring tension, it allows the two pressure rollers 20 to press down the grinding and polishing belt 5 smoothly, thereby offsetting it from other grinding and polishing belts 5 and facilitating the use of the grinding and polishing belt 5.

[0017] Example 3; as Figure 1 and Figure 2 As shown, the present invention proposes a novel steel processing and polishing machine. Compared with Embodiment 1, this embodiment details the moving structure of the lifting frame a12. A vertical plate 13 is provided on the frame 1, and a strip groove 14 is provided on the lifting frame a12. The vertical plate 13 passes through the strip groove 14. The front-to-back length of the strip groove 14 is greater than the front-to-back length of the vertical plate 13. The lifting frame a12 can move up and down on the vertical plate 13, and it can also move back and forth.

[0018] Furthermore, a U-shaped plate is provided at the front end of the lifting frame a12, with the U-shaped groove opening on the U-shaped plate facing downwards. U-shaped frames b19 are provided at both ends of the bottom of the U-shaped plate. The pressure roller 20 is rotatably mounted on the U-shaped frame b19. The pressure roller 20 abuts against a polishing belt 5 from the inside and presses down, so that the polishing belt 5 is staggered from other polishing belts 5, thereby facilitating the use of the polishing belt 5 for polishing work.

[0019] Furthermore, it also includes a lifting frame b15 and a telescopic device a16 horizontally mounted on the lifting frame b15. The telescopic device a16 is arranged in the front-to-back direction, and its telescopic end is connected to the lifting frame a12. The telescopic device a16 drives the lifting frame a12 to move in the front-to-back direction. The telescopic device a16 is a cylinder, a hydraulic cylinder, or an electric push rod. A mounting frame 18 is provided on the frame 1, and a telescopic device b17 is vertically mounted on the mounting frame 18. The top of the telescopic end of the telescopic device b17 is connected to the lifting frame b15. The telescopic device b17 drives the lifting frame b15 to move up and down, thereby controlling the up and down movement of the lifting frame a12. The telescopic device b17 is a cylinder, a hydraulic cylinder, or an electric push rod.

[0020] Example 4; The polishing method proposed in this invention, using the novel steel processing polishing machine of Example 4, specifically includes the following steps: S1. The telescopic device b17 retracts, causing the lifting frame a12 to move downward. Through the two pressure rollers 20, a polishing belt 5 is pressed down and moved downward to be offset from other polishing belts 5. S2. When it is necessary to change the grit size, the lifting frame a12 should be moved up first, and then moved back and forth to the position of the required polishing belt 5. S3. The telescopic device b17 retracts, causing the lifting frame a12 to move downward. The two pressure rollers 20 press down on the polishing belt 5 and move it downward to be offset from other polishing belts 5. This allows for the switching of polishing belts 5 with different grit sizes. It eliminates the need to manually remove the polishing belt 5 and reinstall other polishing belts 5, making it more convenient to use and improving work efficiency.

[0021] In summary, in this invention, by changing the position of the lifting frame a12, different polishing belts 5 can be pressed down, thereby using polishing belts 5 with the required grit. When switching between different polishing belts 5, the tensioning wheel 6 can always keep the polishing belts 5 taut, ensuring that the polishing belts 5 can complete the polishing work smoothly. There is no need to manually remove the polishing belts 5 and reinstall other polishing belts 5, making it more convenient to use and improving work efficiency.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
