Description

[0002] Metal materials refer to metal elements or materials with metal properties that are mainly composed of metal elements. They include pure metals, alloys, metal material intermetallic compounds, and special metal materials. Among them, metal pipes are a common metal material product. When treating the surface of metal pipes, polishing equipment is needed to polish the inner and outer surfaces of the metal pipes to reduce burrs.

[0003] The existing metal tube polishing equipment can generally only perform single polishing on the inner wall or outer wall of the metal tube when in use. After the outer wall polishing is completed, the metal tube needs to be removed and then installed on the inner wall polishing machine to polish the inner wall. The metal tube needs to be clamped and fixed and disassembled continuously. The operation steps are cumbersome. In addition, the sizes of metal tubes in different batches vary greatly. When polishing and grinding metal tubes of different sizes, the equipment parameters need to be readjusted. The operation is relatively complicated, which greatly reduces the processing efficiency. To this end, we propose a metal material surface treatment equipment. Summary of the invention

The output end of the driving motor 44 is coaxially fixedly connected with a driving gear 45, and the outer wall of the driving tube 17 is fixedly connected with an outer gear ring 46 that meshes with the driving gear 45.

[0023] See also Figure 3-Figure 12 The pushing member 20 shown in the figure includes multiple groups of rotating rods 21 rotatably connected to the side of the first grinding rod 9, and the outer wall of the sliding tube 8 is evenly provided with multiple groups of rotating grooves 22.

A driving member 27 is provided on the machine body 1 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 position.

[0024] See also Figure 1-Figure 12 The driving member 27 shown in the figure includes a sleeve tube 28 coaxially fixedly connected to the driving tube 17, the outer wall of the sliding tube 8 is slidably fitted with the inner wall of the sleeve tube 28, one end of the push rod 23 is fixedly connected to a second tension spring 29 fixedly connected to the sliding tube 8, a fixed tube 30 is fixedly connected to the body 1, both ends of the fixed tube 30 are connected to a telescopic tube 31 that can be telescoped in the horizontal and vertical directions, one end of the sleeve tube 28 is rotatably connected to one end of the telescopic tube 31, the sleeve tube 28 is connected to the telescopic tube 31, the fixed tube 30 is used to store hydraulic oil, and a control member 32 for controlling the liquid pressure in the fixed tube 30 is provided in the body 1.

[0025] In this embodiment, the metal tube 48 to be polished is placed horizontally on the transmission belt 6, and the metal tube 48 automatically rolls to the middle depression of the arc-shaped support frame 4 for preliminary positioning, and the second electric telescopic rod 42 is started to push the dust box 43 downward until the bottom end of the second polishing rod 11 conflicts with the upper outer wall of the metal tube 48. At this time, one end of the first connecting rod 15 and the second connecting rod 16 are at the same distance from the metal tube 48. The first connecting rod 15 and the second connecting rod 16 drive the adjustment plate 14 to perform vertical lifting and lowering, and at the same time drive the sliding frame 12 to perform horizontal sliding adjustment, so that the axis of the sliding tube 8 is aligned with the axis of the metal tube 48, so as to realize the automatic positioning of the position height of the sliding tube 8. During adjustment, the telescopic tube 31 is always used to keep the fixed tube 30 and the sleeve tube 28 connected. The device can automatically identify the diameter size of the metal tube 48, and there is no need to manually adjust the position parameters of the equipment, nor is there any need to transport, align and clamp the metal tube 48, thereby greatly improving the disassembly and assembly efficiency.

[0026] The start control component 32 pressurizes the fixed tube 30 and inputs the hydraulic oil into the sleeve tube 28 through the telescopic tube 31. The hydraulic pressure in the sleeve tube 28 increases, pushing the sliding tubes 8 on both sides to slide toward each other. At this time, due to the tension of the second tension spring 29, the push rod 23 will preferentially maintain a slightly sliding state until the first grinding rods 9 at both ends collide with each other. Thereafter, the hydraulic pressure in the sleeve tube 28 continues to increase, which can make the push rod 23 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 grinding rod 9 on the side gradually expands outward until it fits with the inner wall of the metal tube 48. At this time, the contact force between the first grinding rod 9 and the inner wall of the metal tube 48 is small.

[0027] Start the drive motor 44 to drive the drive gear 45 to rotate, so that the outer gear ring 46 drives the drive tube 17 to rotate, and the drive tube 17 drives the limit rod 18 to rotate the sliding tube 8, so that the first grinding rod 9 can be rotated and ground against the inner wall of the metal tube 48, thereby realizing the automatic grinding operation of the inner wall of the metal tube 48.

[0028] After the inner wall grinding is completed, the control member 32 is continuously driven to increase the pressure in the fixed tube 30, thereby increasing the hydraulic pressure in the sleeve tube 28 and the sliding tube 8, and the push rod 23 continues to slide, increasing the resistance of the first grinding rod 9 to the inner wall of the metal tube 48, and then the driving motors 44 on both sides are started 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, and the outer wall of the metal tube 48 is subjected to the outer wall grinding operation under the resistance of the second grinding rod 11. After the grinding is completed, By lowering the hydraulic pressure in the fixed tube 30 through the control member 32, the first grinding rod 9 can be pulled by the first tension spring 26 to fit and reset toward the sliding tube 8, and the second tension spring 29 drives the push rod 23 to reset, and then the sliding tube 8 is pulled back into the sleeve tube 28 and slides out of the metal tube 48. The second electric telescopic rod 42 is controlled to drive the dust collection box 43 and the second grinding rod 11 to move up and reset, so as to release the clamping of the metal tube 48, and the metal tube 48 can be directly removed to carry out the grinding operation of the next group of metal tubes 48.

[0029] It is worth noting that: during the grinding and polishing process, the dust generated during the grinding process can be sucked out through the dust suction box 43. Since the device is used for polishing operations, the metal tube 48 whose inner and outer walls are relatively smooth is polished. After the first grinding rod 9 and the second grinding rod 11 are in contact with the inner and outer walls of the metal tube 48, only a slight position adjustment is required to achieve the polishing operation. No large displacement is required 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 driving tube 17 without affecting the continued sliding adjustment of the sliding tube 8.

[0030] The metal tube 48 of the device does not need to be aligned and can be directly placed on the transmission belt 6. 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 in and clamp, ensuring that no matter where the metal tube 48 is, its inner wall can be fully polished. At the same time, the top of the first polishing rod 9 is longer than the top position of the sliding tube 8, ensuring that the tops of the first polishing rods 9 on both sides can contact each other, avoiding direct contact between the tops of the sliding tubes 8 on both sides, resulting in a section of the middle of the metal tube 48 that cannot be polished. Example 2

[0031] See also Figure 1-Figure 6Embodiment 2 is described. This embodiment further describes Embodiment 1. Both ends of the driving shaft 5 shown in the figure are coaxially fixedly connected with a limiting tooth ring 33. A lifting plate 34 is slidably connected to the body 1 in the vertical direction. A plug-in rod 35 that can be plugged into the tooth groove on the outer wall of the limiting tooth ring 33 is fixedly connected to the lifting plate 34. A return spring 36 that is fixedly connected to the body 1 is fixedly connected to the bottom of the lifting plate 34. A connecting pipe 37 that is connected to the fixed pipe 30 is fixedly connected to the body 1. A lifting block 38 that is slidably connected to the inner wall of the connecting pipe 37 in the vertical direction is fixedly connected to the lifting plate 34.

[0032] In the present embodiment, when the first grinding rod 9 is grinding the inner wall of the metal tube 48, the pressure in the fixed tube 30 is not enough to push the lifting block 38 downward. At this time, the reset spring 36 lifts the plug-in rod 35, so that the plug-in rod 35 resists and limits the limiting tooth 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, the second grinding rod 11 clamps the top of the metal tube 48 to ensure the fixation of the position of the metal tube 48. At this time, the inner wall of the metal tube 48 can be better ground and polished. Among them, the first tension spring 26, the second tension spring 29 and the reset tension spring all need to be regularly inspected and replaced to ensure the stable operation of the equipment.

[0033] When the hydraulic pressure in the fixed tube 30 is increased so that the first grinding rod 9 can drive the metal tube 48 to rotate together, the pressure in the fixed tube 30 and the connecting tube 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 connecting rod 35 to move slightly downward, and the elastic strength of the reset spring 36 is greater than the strength of the second tension spring 29, ensuring that as the hydraulic pressure increases, the sliding tube 8 slides first, the pushing rod 23 slides again, and the lifting block 38 slides last. At this time, the connecting rod 35 releases the connection with the limit gear ring 33, so that the drive shaft 5 can rotate freely. At this time, the metal tube 48 will drive the transmission belt 6 to rotate synchronously during the rotation process, and the rolling friction greatly reduces the resistance to the rotation of the metal tube 48. The metal tube 48 is only subjected to the resistance of the second grinding rod 11 for outer wall grinding, and the operation is smoother and more stable. Example 3

[0034] See also Figure 1-Figure 6 Embodiment 3 is described. This embodiment further describes Embodiment 1. The control component 32 shown in the figure includes a storage cylinder 39 fixedly installed in the body 1. One end of the storage cylinder 39 is connected to the middle part of the fixed tube 30. A first electric telescopic rod 40 is fixedly connected in the body 1. The telescopic end of the first electric telescopic rod 40 is fixedly connected to a driving plate 41. The driving plate 41 is connected to the inner wall of the storage cylinder 39 in a horizontal sliding direction. The fixed frame 2 is provided with a control key 47 for monitoring and adjusting the hydraulic strength in the fixed tube 30.

[0035] 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 to increase the liquid pressure in the fixed cylinder. Conversely, the driving plate 41 is driven to slide in the opposite direction to reduce the hydraulic pressure in the fixed cylinder. The liquid pressure value in the fixed cylinder is controlled by the control key 47. When the value is T0, it means that the liquid pressure in the fixed cylinder is 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 value is reached, the liquid pressure 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 will not drive the lifting plate 34 to move downward. At this time, it is the inner wall grinding state. When the value reaches T2 value, the liquid pressure is relatively large, and the lifting plate 34 can be pressed down to release the limit on the drive shaft 5. At the same time, the first grinding rod 9 is in close contact with the inner wall of the metal tube 48, and the metal tube 48 can be driven by the first grinding rod 9 to rotate synchronously to realize the outer wall grinding operation.
