Description

Technical Field

[0001] The present invention relates to the technical field of metal surface polishing, and specifically relates to a metal material surface treatment device. Background Art

[0002] Metal materials refer to the general term of materials composed of metal elements or mainly composed of metal elements with metallic properties. It includes pure metals, alloys, intermetallic compounds of metal materials, and special metal materials, etc.; among them, metal pipes are a common metal material product. When treating the surface of a metal pipe, a polishing device is required to polish and grind the inner and outer surfaces of the metal pipe to reduce burrs.

[0003] The existing metal pipe polishing devices generally can only perform single polishing on the inner wall or the outer wall of the metal pipe during use. After the outer wall polishing is completed, the metal pipe needs to be removed and then installed on the inner wall polishing machine for inner wall polishing. It is necessary to continuously clamp, fix and disassemble the metal pipe, and the operation steps are cumbersome. Moreover, the sizes of metal pipes in different batches vary greatly. When polishing and grinding metal pipes of different sizes, it is necessary to re-adjust the device parameters, and the operation is relatively complex, which greatly reduces the processing efficiency. For this reason, we propose a metal material surface treatment device. Summary of the Invention

For driving the sliding tubes 8 to extend into the metal tube 48 and controlling the first grinding rods 9 to contact the inner wall of the metal tube 48, and then driving the sliding tubes 8 to rotate to realize the inner wall grinding operation of the metal tube 48.

[0032] Please refer to Figures 1 - 8 , the outer wall grinding mechanism 10 in the figure includes a second grinding rod 11 installed on the fixed frame 2. Two sliding frames 12 are slidably connected in the horizontal direction between the machine body 1 and the fixed frame 2. A synchronizing member 13 for synchronously adjusting the axis of the sliding tube 8 to be aligned with the axis of the metal tube 48 when the second grinding rod 11 moves up and down is provided in the sliding frame 12. For contacting the top of the metal tube 48 with the second grinding rod 11, so that the synchronizing member 13 adjusts the height of the sliding tube 8, and after the inner wall grinding is completed, by increasing the contact force between the first grinding rod 9 and the metal tube 48, the sliding tube 8 drives the metal tube 48 to rotate synchronously, so that the second grinding rod 11 grinds the outer wall of the metal tube 48.

[0033] Please refer to Figures 1 - 10, the synchronizing member 13 in the figure includes an adjusting plate 14 slidably connected to the sliding frame 12 in the vertical direction. The sliding tube 8 is installed on the adjusting plate 14. Both sides of the support frame 4 are rotatably connected to a first connecting rod 15 rotatably connected to the adjusting plate 14.

The telescopic end of the second electric telescopic rod 42 is fixedly connected to a dust suction box 43. The second polishing rod 11 is fixedly connected to the bottom surface of the dust suction box 43.

[0034] Please refer to Figures 1 - 10 , the inner wall polishing mechanism 7 in the figure further includes a driving tube 17 rotatably connected to the adjusting plate 14. The driving tube 17 penetrates the adjusting plate 14 and is at the middle height between the first connecting rod 15 and the second connecting rod 16. The sliding tube 8 penetrates the driving tube 17. A limiting rod 18 fixedly connected to the outer wall of the sliding tube 8 is slidably connected to the driving tube 17 in the horizontal direction. The cross-section of the limiting rod 18 is the same as that of the first polishing rod 9. A rotating member 19 for driving the driving tube 17 to rotate is provided on the adjusting plate 14. A pushing member 20 for driving the first polishing rod 9 to abut against the inner wall of the metal tube 48 is provided in the sliding tube 8. The rotating member 19 includes a driving motor 44 fixedly installed on the adjusting plate 14. The model of the driving motor 44 is preferably YYHS-40. The output end of the driving motor 44 is coaxially fixedly connected to a driving gear 45. An external tooth ring 46 meshing with the driving gear 45 is fixedly connected to the outer wall of the driving tube 17.

[0035] Please refer to Figures 3 - 12 , the pushing member 20 in the figure includes multiple rotating rods 21 rotatably connected to the side surface of the first polishing rod 9. Multiple rotating grooves 22 are evenly formed on the outer wall of the sliding tube 8. The middle parts on both sides of the rotating rod 21 are rotatably connected to the rotating grooves 22. A pushing rod 23 and multiple pushing blocks 24 are slidably connected in the sliding tube 8. The side surface of the pushing block 24 abuts against one end of the rotating rod 21. A third connecting rod 25 is fixedly connected between the multiple pushing blocks 24. A first tension spring 26 is fixedly connected between the first polishing rods 9 on the same sliding tube 8. One end of the pushing rod 23 is fixedly connected to the pushing block 24. A driving member 27 for preferentially pushing the sliding tube 8 to slide and then controlling the pushing rod 23 to slide after the sliding tubes 8 at both ends move to the set positions is provided on the machine body 1.

[0036] Please refer to Figures 1 - 12, in the illustration, the driving member 27 includes a sleeve pipe 28 fixedly connected coaxially with the driving pipe 17. The outer wall of the sliding pipe 8 is in sliding fit with the inner wall of the sleeve pipe 28. One end of the push rod 23 is fixedly connected with a second tension spring 29 fixedly connected with the sliding pipe 8. A fixed pipe 30 is fixedly connected to the machine body 1. Both ends of the fixed pipe 30 are connected and communicated with telescopic pipes 31 capable of telescoping in the horizontal and vertical directions. One end of the sleeve pipe 28 is rotatably connected to one end of the telescopic pipe 31. The sleeve pipe 28 is communicated with the telescopic pipe 31. The fixed pipe 30 is used for storing hydraulic oil, and a control member 32 for controlling the liquid pressure in the fixed pipe 30 is provided in the machine body 1.

[0037] In this implementation scheme, the metal pipe 48 to be polished is horizontally placed on the conveyor belt 6. The metal pipe 48 automatically rolls to the middle concave part of the arc-shaped support frame 4 for preliminary positioning. The second electric telescopic rod 42 is started to push the dust suction box 43 downward until the bottom end of the second polishing rod 11 abuts against the outer wall on the upper side of the metal pipe 48. At this time, the distances from one ends of the first connecting rod 15 and the second connecting rod 16 to the metal pipe 48 are the same. The first connecting rod 15 and the second connecting rod 16 drive the adjusting plate 14 to move vertically, and at the same time drive the sliding frame 12 to slide horizontally for adjustment, so that the axis of the sliding pipe 8 is aligned with the axis of the metal pipe 48, realizing the automatic positioning of the height of the sliding pipe 8. During the adjustment, the communication state between the fixed pipe 30 and the sleeve pipe 28 is always maintained through the telescopic pipe 31. This device can automatically identify the diameter size of the metal pipe 48, without manually adjusting the position parameters of the equipment, nor transporting, aligning and clamping the metal pipe 48, greatly improving the disassembly and assembly efficiency.

[0038] The control member 32 is started to pressurize the fixed pipe 30, and the hydraulic oil is input into the sleeve pipe 28 through the telescopic pipe 31. The hydraulic pressure in the sleeve pipe 28 increases, and the two side sliding pipes 8 are pushed to slide towards each other. At this time, due to the pulling force of the second tension spring 29, the push rod 23 will preferentially maintain a slightly sliding state until the first polishing rods 9 at both ends abut against each other. After that, the hydraulic pressure in the sleeve pipe 28 continues to increase, so that the push rod 23 can slide, the second tension spring 29 is stretched, and the push block 24 pushes one end of the third connecting rod 25 to rotate, so that the first polishing rods 9 on the side gradually expand outwards until they are in contact with the inner wall of the metal pipe 48. At this time, the contact force between the first polishing rod 9 and the inner wall of the metal pipe 48 is small.

[0039] The driving motor 44 is started to drive the driving gear 45 to rotate, so that the external gear ring 46 drives the driving pipe 17 to rotate. The driving pipe 17 drives the limiting rod 18 to make the sliding pipe 8 rotate, so that the first polishing rod 9 can rotate and polish along the inner wall of the metal pipe 48, realizing the automatic polishing operation of the inner wall of the metal pipe 48.

[0040] After the inner wall grinding is completed, continue to drive the control member 32 to pressurize the inside of the fixed tube 30, so that the hydraulic pressure in the sleeve tube 28 and the sliding tube 8 increases, the push rod 23 continues to slide, increasing the contact force of the first grinding rod 9 against the inner wall of the metal tube 48. After that, start the drive motors 44 on both sides again to drive the sliding tube 8 and the first grinding rod 9 to rotate synchronously, which can drive the metal tube 48 to rotate synchronously. The outer wall of the metal tube 48 is ground under the contact of the second grinding rod 11. After the grinding is completed, lower the hydraulic pressure in the fixed tube 30 through the control member 32, so that the first grinding rod 9 fits and resets towards the sliding tube 8 under the pull of the first tension spring 26, and the second tension spring 29 drives the push rod 23 to reset. Then, the sliding tube 8 is pulled back into the sleeve tube 28 and slides out of the metal tube 48. Control the second electric telescopic rod 42 to drive the dust suction box 43 and the second grinding rod 11 to move up and reset to release the clamping of the metal tube 48, and directly take away the metal tube 48 to perform the grinding operation on the next group of metal tubes 48.

[0041] It should be noted that during the grinding and polishing process, by sucking through the dust suction box 43, the dust generated during the grinding process can be sucked. Since this device is used for polishing operations and is for polishing the metal tube 48 with relatively smooth inner and outer walls, after the first grinding rod 9 and the second grinding rod 11 come into contact with the inner and outer walls of the metal tube 48, only slight position adjustment is required to achieve the polishing operation, and there is no need for large displacement during the polishing process. Since the cross-section of the limit rod 18 is the same as that of the first grinding rod 9, when the sliding tube 8 slides to the set position, the first grinding rod 9 can slide into the drive tube 17 without affecting the continuous sliding adjustment of the sliding tube 8.

[0042] The metal tube 48 of this device does not need to be aligned. It can be directly placed on the conveyor belt 6, and there is no need to ensure that the metal tube 48 is in the center position. The sliding tubes 8 at both ends automatically extend into the clamping, ensuring that no matter where the metal tube 48 is, its inner wall can be polished comprehensively. At the same time, the top of the first grinding rod 9 is longer than the top of the sliding tube 8, ensuring that the tops of the first grinding rods 9 on both sides can contact each other, avoiding the situation where a section in the middle of the metal tube 48 cannot be ground and polished due to the direct contact of the tops of the sliding tubes 8 on both sides. Embodiment 2

[0043] Please refer to Figures 1 - 6Description of Embodiment 2. This embodiment further illustrates Embodiment 1. At both ends of the drive shaft 5 in the figure, there are coaxially and fixedly connected limit gear rings 33. Inside the machine body 1, there is a lifting plate 34 slidably connected in the vertical direction. Fixedly connected to the lifting plate 34 is a plugging rod 35 that can be inserted into the tooth grooves on the outer wall of the limit gear ring 33. Fixedly connected to the bottom of the lifting plate 34 is a return spring 36 fixedly connected to the machine body 1. Inside the machine body 1, there is a connecting pipe 37 fixedly connected and communicating with the fixed pipe 30. Fixedly connected to the lifting plate 34 is a lifting block 38 slidably connected to the inner wall of the connecting pipe 37 in the vertical direction.

[0044] In this implementation scheme, when the first grinding rod 9 grinds the inner wall of the metal pipe 48, the pressure in the fixed pipe 30 at this time is not sufficient to push the lifting block 38 downward. At this time, the return spring 36 pushes up the plugging rod 35, causing the plugging rod 35 to abut and limit the limit gear ring 33, ensuring that the drive shaft 5 cannot rotate at this time, and the position of the transmission belt 6 is relatively fixed. At the same time, in cooperation with the clamping of the top of the metal pipe 48 by the second grinding rod 11, the position of the metal pipe 48 is ensured to be fixed. At this time, the inner wall of the metal pipe 48 can be better polished. Among them, the first tension spring 26, the second tension spring 29, and the return tension spring all need to be regularly inspected and replaced to ensure the stable operation of the equipment.

[0045] When increasing the hydraulic pressure in the fixed pipe 30 so that the first grinding rod 9 can drive the metal pipe 48 to rotate together, at this time, the pressure in the fixed pipe 30 and the connecting pipe 37 continues to increase to a strength that can push the lifting block 38 downward, so that the lifting block 38 drives the lifting plate 34 and the plugging rod 35 to move slightly downward. The elastic strength of the return spring 36 is greater than that of the second tension spring 29, ensuring the order of the sliding tube 8 sliding first, the pushing rod 23 sliding next, and the lifting block 38 sliding last as the hydraulic pressure increases. At this time, the plugging of the plugging rod 35 to the limit gear ring 33 is released, and the drive shaft 5 can rotate freely. At this time, the metal pipe 48 will drive the transmission belt 6 to rotate synchronously during the rotation process, greatly reducing the resistance to the rotation of the metal pipe 48 through rolling friction. The metal pipe 48 is only abutted by the second grinding rod 11 for outer wall grinding, and the operation is more smooth and stable. Embodiment 3

[0046] Please refer to Figures 1 - 6 Description of Embodiment 3. This embodiment further illustrates Embodiment 1. The control member 32 in the figure includes a storage cylinder 39 fixedly installed inside the machine body 1. One end of the storage cylinder 39 is connected and communicated with the middle part of the fixed pipe 30. Inside the machine body 1, there is a first electric telescopic rod 40 fixedly connected. The telescopic end of the first electric telescopic rod 40 is fixedly connected with a drive plate 41. The drive plate 41 is slidably connected to the inner wall of the storage cylinder 39 in the horizontal direction. On the fixed frame 2, there is an operation key 47 for monitoring and adjusting the hydraulic strength in the fixed pipe 30.

[0047] In this embodiment, by starting the first electric telescopic rod 40 to drive the driving plate 41 to slide in the storage cylinder 39, the hydraulic oil in the storage cylinder 39 is squeezed into the fixed cylinder, so that the liquid pressure in the fixed cylinder can be increased. Conversely, driving the driving plate 41 to slide in the reverse direction can reduce the hydraulic pressure in the fixed cylinder. The numerical value of the liquid pressure in the fixed cylinder is controlled by the control button 47. When the numerical value is T0, it means that the liquid pressure in the fixed cylinder is relatively low, and the sliding tube 8 is at the two ends. At this time, the metal tube 48 can be loaded and unloaded. When the set T1 numerical value is reached, the liquid pressure at this time can just push the push rod 23 so that the first grinding rod 9 slightly contacts the inner wall of the metal tube 48, and it will not drive the lifting plate 34 to move downward. At this time, it is the inner wall grinding state. When the numerical value reaches the T2 value, the liquid pressure is relatively large at this time, which can press down the lifting plate 34 to release the limit on the drive shaft 5. At the same time, the first grinding rod 9 tightly contacts the inner wall of the metal tube 48, and the metal tube 48 can be driven to rotate synchronously through the first grinding rod 9 to realize the outer wall grinding operation.
