Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, and specifically, to a device for processing burrs on the edge of a stainless steel pipe. Background Art

[0002] Stainless steel pipes are hollow long round steel materials, which are mainly widely used in industrial conveying pipelines such as petroleum, chemical industry, medical treatment, food, light industry, and mechanical instruments, as well as mechanical structure components, etc. When stainless steel pipes are actually applied, they need to be cut to a required length according to needs. In this way, burrs are likely to appear at the cut places of the stainless steel pipes. Therefore, in order to make the cut stainless steel pipes smoother and more beautiful, a device for grinding burrs is needed.

[0003] The existing patent with publication number CN216178333U discloses an integrated device for cutting and deburring stainless steel pipes, which relates to the technical field of steel pipe cutting. It includes a workbench, the four corners of the bottom of the workbench are connected with connecting plates, a cutting assembly is installed on the top of the workbench, a grinding assembly is connected to the surface of the connecting plate, and a steel pipe limiting seat is connected to the edge of the surface of the workbench. By inserting the steel pipe into the fixed cylinder, turning the bolt, and pushing the arc-shaped pressing plate downward to make the arc-shaped pressing plate press against the steel pipe to fix it, preventing it from shaking during the cutting of the steel pipe. Using the first pushing cylinder to move downward to drive the fixed plate to descend, and moving the steel pipe inside the fixed cylinder to the grinding assembly, without manual taking, improving work efficiency and safety. By moving the steel pipe to the grinding sandpaper, using two motors to drive the sandpaper seat to make the grinding sandpaper rotate to grind the steel pipe. Through the integrated device of cutting and grinding, the work efficiency is greatly improved.

[0004] The above-mentioned solution has the following problems during implementation. After the device cuts the steel pipe, it moves the steel pipe to the grinding place, and then grinds the end face of the steel pipe through the grinding sandpaper. However, this device is not convenient for grinding the inner wall edge and outer wall edge of the steel pipe. When the steel pipe is cut, not only the cutting end face will have burrs, but also the edge of the cutting end face will have burrs. Therefore, the device does not grind comprehensively enough, resulting in the finally processed steel pipe still not being smooth and beautiful enough, greatly reducing the practicability of the device. For this reason, we provide a device for processing burrs on the edge of a stainless steel pipe to solve the above problems. Summary of the Utility Model

Therefore, the device does not grind comprehensively enough, resulting in the finally processed steel pipe still not being smooth and beautiful enough, greatly reducing the practicability of the device.

[0006] The utility model provides the following technical solution: a burr treatment device for the edge of a stainless steel pipe, including a workbench.

Detailed Embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a technical solution: a device for processing burrs on the edge of a stainless steel pipe, including a workbench 1. On one side of the top end of the workbench 1, a grinding mechanism for grinding burrs on the stainless steel pipe is installed. The grinding mechanism includes an end face grinding assembly 2 for grinding burrs on the end face of the stainless steel pipe, an inner wall edge grinding assembly 3 for grinding burrs on the inner wall edge of the stainless steel pipe, and two outer wall edge grinding assemblies 4 for grinding burrs on the outer wall edge of the stainless steel pipe. On the side of the top end of the workbench 1 away from the grinding mechanism, a fixing assembly 5 for clamping and fixing the stainless steel pipe is installed. The end face grinding assembly 2 includes a support plate 21. The support plate 21 is fixedly installed on the top end of the workbench 1. One end of the support plate 21 is provided with a first motor 22, and the output end of the first motor 22 passes through the support plate 21 and is connected to a grinding disc 23. This structure enables the grinding disc 23 to rotate driven by the first motor 22, so as to grind the end face of the steel pipe after cutting, making the end face of the steel pipe more beautiful and smooth, and greatly increasing the practicability of the device.

[0022] As an implementation manner in this embodiment, as Figure 3As shown in the figure, the inner wall edge grinding assembly 3 and two groups of outer wall edge grinding assemblies 4 are both installed on the side of the grinding disc 23 close to the fixing assembly 5. The inner wall edge grinding assembly 3 includes a first chute 31 and a second motor 32. The first chute 31 is opened at one end of the grinding disc 23 close to the fixing assembly 5, and the second motor 32 is installed at the side end of the grinding disc 23. A first bidirectional screw 33 is rotatably installed in the first chute 31, and one end of the first bidirectional screw 33 is connected to the output end of the second motor 32. Threaded sleeves 34 are sleeved on both sides of the surface of the first bidirectional screw 33. Grinding blocks 35 are installed at the outer ends of the two groups of threaded sleeves 34. This structure can grind the inner wall edge of the steel pipe close to the cutting end face. Moreover, by driving the first bidirectional screw 33 to rotate through the second motor 32, the threaded sleeves 34 and the grinding blocks 35 can be driven to move, so as to adjust the distance between the two groups of grinding blocks 35, making the grinding blocks 35 fit the inner wall of the steel pipe. In this way, steel pipes with different inner diameters can be ground. The two groups of outer wall edge grinding assemblies 4 include connecting plates 41. The two groups of connecting plates 41 are respectively connected to both sides of one end of the grinding disc 23 close to the fixing assembly 5. Nuts 42 are embedded on the surfaces of the two groups of connecting plates 41. One-way screws 43 are threadedly inserted into the two groups of nuts 42. Grinding blocks 44 are installed at the ends of the two groups of one-way screws 43 close to each other, and the grinding blocks 44 are rotatably connected to the one-way screws 43. In order to limit the grinding blocks 44 so that the grinding blocks 44 can be translated, limit rods 45 are connected to both sides of the surfaces of the two groups of grinding blocks 44 close to the two groups of connecting plates 41 respectively, and the ends of the limit rods 45 far from the grinding blocks 44 penetrate through the connecting plates 41 and extend to the outside of the connecting plates 41. This structure enables the grinding blocks 44 to be pushed close to the outer wall of the steel pipe by rotating the one-way screws 43 until the grinding blocks 44 fit the outer wall of the steel pipe. In this way, the outer wall edge of the steel pipe close to the cutting end face can be ground, so that steel pipes with different outer diameters can be ground, greatly increasing the comprehensiveness of grinding of the device and making the grinding of the steel pipe smoother and more beautiful. Knobs 46 are installed at the ends of the two groups of one-way screws 43 far from the two groups of grinding blocks 44 respectively, making it more convenient to operate and rotate the one-way screws 43 through the knobs 46.

[0023] It should be noted that the two groups of grinding blocks 35 and the two groups of grinding blocks 44 are both arc-shaped, so that they can fit the inner and outer walls of the cylindrical steel pipe more closely. Moreover, the ends of the two groups of grinding blocks 35 and the two groups of grinding blocks 44 close to the second motor 32 are relatively close to the end face of the second motor 32. In this way, when grinding, the edges can be better ground.

[0024] Furthermore, considering that the side end of the grinding disc 23 is arc-shaped, a backing plate is installed at the position where the second motor 32 is installed on the side end of the grinding disc 23. In this way, the second motor 32 can be installed on the side end of the grinding disc 23 through the backing plate, which is more stable. The output end of the second motor 32 also passes through the backing plate and is connected to the first bidirectional screw 33.

[0025] As an implementation manner in this embodiment, as Figure 4 shown, the fixing assembly 5 includes a fixing plate 51. The fixing plate 51 is fixedly connected to the top end of the workbench 1. A second chute 52 is opened at one end of the fixing plate 51, and a second bidirectional screw 53 is rotatably installed in the second chute 52. The top end of the second bidirectional screw 53 is installed with a handle 54 through a rotating shaft passing through the fixing plate 51, which makes it more convenient to drive the second bidirectional screw 53 to rotate by operating the handle 54. Threaded sleeves 55 are sleeved on the upper and lower sides of the surface of the second bidirectional screw 53. Connecting rods 56 are connected to the outer ends of the two threaded sleeves 55. Clamping plates 57 are installed at the ends of the two connecting rods 56 close to each other. This structure enables the distance between the two connecting rods 56 to be adjusted by rotating the second bidirectional screw 53, so that steel pipes with different diameters can be clamped and fixed. Moreover, in this way, it is not necessary to hold the steel pipe by hand for grinding, which is more labor-saving and convenient, greatly increasing the convenience of the device. The two clamping plates 57 are both arc-shaped, making them more suitable for the cylindrical steel pipe. Rubber pads 58 are glued to the inner walls of the two clamping plates 57, so that the friction when contacting the steel pipe can be increased, making the clamping of the steel pipe more stable and not easy to shake.

[0026] It should be noted that the center points between the two clamping plates 57 and the center point of the grinding disc 23 are on the same horizontal line. In this way, when fixing the steel pipe, the center of the steel pipe can better correspond to the center of the grinding disc 23, so that when adjusting the positions of the two first grinding blocks 35 and the two second grinding blocks 44, the two first grinding blocks 35 and the two second grinding blocks 44 can better fit the steel pipe.

[0027] Working principle: If it is necessary to grind the steel pipe, only need to face the cutting end face of the steel pipe towards the grinding disc 23, then place it between the two clamping plates 57. At the same time, make the cutting end face of the steel pipe fit and abut against the grinding disc 23, and sleeve the steel pipe outside the two first grinding blocks 35. Then, the handle 54 can be held by hand and rotated. The handle 54 drives the second bidirectional screw 53 to rotate. Through thread rotation, the second bidirectional screw 53 drives the two threaded sleeves 55 to approach each other. The two threaded sleeves 55 drive the two connecting rods 56, the two connecting rods 56 drive the two clamping plates 57, and the two clamping plates 57 drive the two rubber pads 58 until the two rubber pads 58 fit the steel pipe, and the steel pipe can be clamped and fixed by the two clamping plates 57;

[0028] In addition, after the steel pipe is fixed, only need to start the second motor 32 to drive the first bidirectional screw 33 to rotate. Through the thread rotation, the first bidirectional screw 33 drives the two sets of first screw sleeves 34 to move away from each other until the two sets of first screw sleeves 34 drive the two sets of first grinding blocks 35 to fit against the inner wall of the steel pipe. Then, hold the knob 46 in turn and rotate it. The knob 46 drives the unidirectional screw 43 to rotate. Through the rotation of the unidirectional screw 43 in the nut 42, the unidirectional screw 43 can push the second grinding block 44 towards the steel pipe until the two sets of second grinding blocks 44 both fit against the outer wall of the steel pipe. Then, the first motor 22 can be started to drive the grinding disc 23 to rotate. At the same time, the grinding disc 23 will also drive the two sets of first grinding blocks 35 and the two sets of second grinding blocks 44 to rotate, so as to realize grinding.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
