[0002] In the field of metal processing, steel pipe reaming is a common machining process, widely used in pipe connections, mechanical assembly and other applications.

[0003] Currently, common steel pipe reaming equipment on the market mainly consists of a clamping mechanism and a reaming mechanism. Its working principle is to first fix the steel pipe on the clamping mechanism, and then use a reaming mandrel to expand the inner diameter of the steel pipe. During the reaming process, in order to reduce the friction between the reaming mandrel and the inner wall of the steel pipe, lubricating oil is usually added. However, the steel pipe reaming equipment on the market currently lacks a cleaning function. After the reaming is completed, the lubricating oil remaining on the surface of the steel pipe needs to be cleaned manually or allowed to drip onto the ground, which increases costs and easily pollutes the working environment. Therefore, improvements are needed. Utility Model Content

[0019] Reference Figures 1-4According to an embodiment of the present invention, a steel pipe reaming machine includes a machine base 11, on which a clamping mechanism and a reaming mechanism are provided. The clamping mechanism is used to lock the steel pipe, while the reaming mechanism is used to ream the steel pipe.

[0020] In this embodiment, the clamping mechanism includes a first support plate 21 fixed on the machine base 11, and a pressure plate 22 is provided on the upper side of the first support plate 21. Arc-shaped grooves for accommodating and positioning steel pipes are respectively provided on the sides of the first support plate 21 and the pressure plate 22 that are close to each other. It also includes a lifting control component for controlling the up and down movement of the pressure plate 22.

[0021] like Figure 1 As shown, the lifting control assembly includes a bracket 51 fixed on the machine base 11. A horizontal plate is fixed on the top surface of the bracket 51, and a second cylinder 52 is fixed on the horizontal plate. The piston rod inside the second cylinder 52 is connected downward to the upper end of the pressure plate 22. In addition, a plurality of first guide rods are provided on the upper end of the pressure plate 22, which penetrate upward through the horizontal plate to ensure the stable lifting of the pressure plate 22.

[0022] In this embodiment, when it is necessary to clamp the steel pipe, the operator controls the pressure plate 22 to be raised to the highest position by the second cylinder 52, and then places the steel pipe in the arc groove in the first support plate 21. After that, the operator controls the pressure plate 22 to sink until the steel pipe is clamped between the pressure plate 22 and the first support plate 21 to complete the locking, which facilitates the subsequent hole enlargement work.

[0023] In order to limit the left and right position of the steel pipe when it is clamped, a rear abutment plate 61 and a second support plate 62 are also fixed on the machine base 11. The second support plate 62 is located between the first support plate 21 and the rear abutment plate 61, and the upper side of the second support plate 62 is also provided with the arc-shaped groove. The rear abutment plate 61 has a vertical surface perpendicular to the axis of the arc-shaped groove.

[0024] When installing the steel pipe, the workers place the steel pipe on the first support plate 21 and the second support plate 62, and make the right end of the steel pipe abut against the rear abutment plate 61. Then, the pressure plate 22 is lowered and locked. This process ensures that the left and right positions of each steel pipe are consistent after locking, and ensures that the enlarged hole area is consistent.

[0025] The reaming mechanism includes a sliding cavity 31 located on the upper side of the machine base 11. A sliding block 32 is slidably connected to the sliding cavity 31 from left to right, and a mounting base 33 is slidably connected to the sliding block 32 from front to back. The mechanism also includes a drive assembly for controlling the movement of the sliding block 32 and the mounting base 33. A reaming mandrel 34 and a cleaning assembly are fixedly mounted on the side of the mounting base 33. An outlet pipe 35 is fixedly mounted on the side of the mounting base 33, directly opposite the reaming mandrel 34.

[0026] The outlet pipe 35 can discharge the lubricating fluid that falls on the reaming mandrel 34 in a timely manner, so as to reduce the wear of the reaming mandrel 34 and the inside of the steel pipe during the reaming operation. The cleaning component is used to clean the lubricating fluid that remains on the steel pipe after the reaming is completed, so as to prevent the lubricating fluid from dripping down after the steel pipe is unloaded and contaminating the working environment.

[0027] To prevent excessive lubricant from dripping into the equipment, an oil receiving plate 36 is fixed on the slide 32. The oil receiving plate 36 is located below the enlarged core rod 34. The guide groove 37 on the upper side of the oil receiving plate 36 is designed as an inclined surface with a lower front and a higher back. A guide pipe is provided at the lowest point of the guide groove 37 so that the lubricant falling into the oil receiving plate 36 can be discharged smoothly.

[0028] Specifically, the cleaning assembly includes an inner column 41 and a hollow tube 42 fitted over the inner column 41. The outer curved surface of the inner column 41 and the inner curved surface of the hollow tube 42 are respectively equipped with cleaning cotton to absorb excess lubricating oil. Furthermore, the right edges of the inner column 41, the hollow tube 42, and the enlarged core rod 34 do not extend to the right side of the oil receiving plate 36, so that the oil receiving plate 36 can be effective.

[0029] Detailed hole enlargement process: After the steel pipe is clamped, the axis of the steel pipe and the axis of the expanding mandrel 34 are at the same height. Then, a certain amount of lubricating fluid flows out of the liquid outlet pipe 35 and lubricates the expanding mandrel 34. Excess lubricating fluid will fall into the oil receiving plate 36 and be recycled or disposed of. Then, the slide block 32 moves to the right to insert the expanding mandrel 34 into the steel pipe and realize the expanding work of the steel pipe. After the hole enlargement is completed, the slide block 32 moves to the left and the mounting base 33 moves backward until the hollow tube 42 and the inner column 41 are directly opposite the steel pipe. Then the slide block 32 moves to the right again so that the cleaning cotton inside the inner column 41 and the hollow tube 42 is attached to the inner and outer walls of the steel pipe, thereby absorbing excess lubricating oil on the surface of the steel pipe. Then the slide block 32 retracts to the left to complete the hole enlargement and cleaning work of the steel pipe.

[0030] In the second embodiment of the steel pipe expanding machine, in order to achieve the oil squeezing operation of the cleaning cotton and avoid reducing its oil absorption function, a compression ring 43 is slidably connected between the inner column 41 and the hollow tube 42. A first cylinder 44 for controlling the left and right position of the compression ring 43 is fixed on the mounting base 33. After the slide block 32 moves to the left and resets, the first cylinder 44 can control the compression ring 43 to move to the right and then reset to the left. This process can squeeze the lubricating oil in the cleaning cotton into the oil receiving plate 36, ensuring the oil absorption effect of the cleaning cotton.

[0031] In addition, the drive assembly includes a third cylinder 71 installed in the machine base 11, and the piston rod in the third cylinder 71 is connected to the right side of the slide block 32. The rear side of the slide block 32 is equipped with a fourth cylinder 72, and the piston rod inside the fourth cylinder 72 is connected to the rear side of the mounting base 33.

[0032] That is, the operator can control the left and right positions of the slide 32 and the mounting base 33 through the third cylinder 71, and control the front and back positions of the mounting base 33 through the fourth cylinder 72, so as to complete the enlargement and cleaning of the steel pipe.

[0033] It should be noted that, as Figure 3 As shown, the connection between the first cylinder 44 and the extrusion ring 43 is as follows: a semi-circular disk is installed at the end of the piston rod inside the first cylinder 44, and multiple sliding rods connected to the extrusion ring 43 are installed on the side of the semi-circular disk to avoid the phenomenon of jamming caused by uneven force on the extrusion ring.

[0034] It should be noted that the liquid supply device for supplying liquid to the outlet pipe may include a liquid storage tank and an electrically controlled pump, wherein the electrically controlled pump can controllably pressurize the lubricating oil in the liquid storage tank into the outlet pipe 35 to discharge liquid; The guide pipe functions as a liquid outlet pipe and can be directly connected to the waste lubricating fluid treatment system. The aforementioned components, control methods, and systems are all conventional setups in the prior art and will not be described in detail here.

[0035] In addition, the piston rod in the third cylinder 71 needs to be reinforced and its center of gravity adjusted with respect to the slide block 32 to prevent it from being misaligned under stress and thus reducing the service life of the third cylinder.

[0036] In addition, a second oil receiving plate can be placed at the bottom of the sliding cavity 31 or on the ground to receive the lubricating oil (not shown in the figure) that drips from the expanded core rod 34 when it is detached from the steel pipe and the steel pipe has not yet been cleaned by the cleaning cotton.

[0037] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
