Description

Technical Field

[0001] This invention belongs to the field of pipe processing technology, specifically relating to a stainless steel pipe processing apparatus and method. Background Technology

[0002] Stainless steel pipes are widely used in chemical, food, pharmaceutical, and construction industries due to their excellent corrosion resistance and strength. During pipe installation, stainless steel pipes often require length cutting, end beveling, and finishing processes such as deburring and chamfering.

[0003] When processing stainless steel pipes, clamping mechanisms are needed to fix and limit the pipe material for cutting and other processing operations. However, existing clamps are not easy to replace and cannot fix different types of pipes. At the same time, the heat generated during pipe processing accumulates rapidly in the tool / pipe contact area or weld area, causing the tool to fail due to rapid dulling at high temperature. The workpiece experiences significant thermal deformation and internal stress, which seriously affects dimensional accuracy and welding quality. Furthermore, the debris generated during processing cannot be disposed of in a timely manner, polluting the working environment and affecting work efficiency.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a stainless steel pipe processing apparatus and method.

[0025] 2. This invention employs a network of annular cooling pipes and branch pipes surrounding the machining area, along with an inclined first and second nozzle, to uniformly and precisely cover the entire contact area between the tool and the workpiece with atomized cooling medium.

Detailed Implementation

[0042] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0043] like Figures 1 to 6 As shown, a stainless steel pipe processing device according to an embodiment of the present invention includes a frame 1, a clamping mechanism 2, a processing mechanism 3, a cooling and chip removal integrated system 4, and a control system. The clamping mechanism 2 includes a first mounting cylinder 21, a second mounting cylinder 22, and a pair of limiting cylinders 23. The first mounting cylinder 21 is fixedly connected to the frame 1 at the left side position. The second mounting cylinder 22 is mounted on the frame 1 at the right side position in a manner that allows it to slide left and right and is coaxial with the first mounting cylinder 21. The pair of limiting cylinders 23 are detachably and coaxially mounted in the first mounting cylinder 21 and the second mounting cylinder 22, respectively. The processing mechanism 3 includes a processing tool 31 and a driving unit. The processing tool 31 is mounted on the frame 1 through the driving unit, and under the action of the driving unit, the processing tool 31 can slide left and right. The cooling and chip removal integrated system 4, which moves back and forth, includes a cooling unit and a chip removal unit. The cooling unit includes an annular cooling pipe 41 and multiple first nozzles 42. The annular cooling pipe 41 is coaxially installed between the first mounting cylinder 21 and the second mounting cylinder 22. The multiple first nozzles 42 are fixedly connected to the side wall of the annular cooling pipe 41 at equal intervals, and the multiple first nozzles 42 are all set in an inclined manner towards the central axis of the annular cooling pipe 41. The chip removal unit is located below the cooling unit for collecting and processing the chips generated during workpiece processing. The control system is signal-connected to the clamping mechanism 2, the processing mechanism 3 and the cooling and chip removal integrated system 4, and is used to control each unit to coordinate its actions according to a preset program to complete the clamping, processing, cooling and chip removal of the workpiece.

[0044] The working principle of this stainless steel pipe processing device is as follows: A combination of a slidingly adjustable second mounting cylinder 22 and a replaceable limiting cylinder 23 enables rapid, centered clamping of stainless steel pipes of different diameters and lengths. Through an annular cooling pipe 41 integrated between the two mounting cylinders and its inclined first nozzle 42, the cooling medium is precisely and evenly sprayed onto the contact area between the tool and the pipe during processing, achieving forced cooling and effectively suppressing thermal deformation and tool wear. A chip removal unit located below the cooling unit collects and initially separates the chips and coolant generated during processing, maintaining a clean working environment. Finally, a unified control system coordinates the clamping, processing, cooling, and chip removal units to work in sequence, thereby efficiently and effectively completing the cutting or end-face processing of stainless steel pipes in a single clamping operation, while simultaneously addressing heat dissipation and cleaning issues.

[0045] like Figure 10 As shown, multiple limiting grooves 24 are equally spaced along the circumference on the inner walls of both the first mounting cylinder 21 and the second mounting cylinder 22. Multiple limiting rods 25 are integrally formed on the outer wall of the limiting cylinder 23, and these rods 25 are slidably connected to the multiple limiting grooves 24. Multiple elastic limiting strips 26 are fixedly connected at equal intervals along the circumference on the inner wall of the limiting cylinder 23. By opening limiting grooves 24 on the inner sides of the first mounting cylinder 21 and the second mounting cylinder 22 and correspondingly setting limiting rods 25 on the outer side of the limiting cylinder 23, rapid positioning and anti-rotation installation of the limiting cylinder 23 are achieved, ensuring its coaxiality with the mounting cylinder. Simultaneously, the elastic limiting strips 26 on the inner side of the limiting cylinder 23 can adapt to different pipe diameters, providing flexible clamping force, protecting the pipe surface, enhancing clamping stability, and further improving the adaptability and reliability of the clamping mechanism.

[0046] like Figure 11 As shown, a pair of mounting plates 27 are provided on the frame 1. A rotating shaft 28 is rotatably connected to each of the mounting plates 27 in a left-right through manner. A sleeve 29 is fixedly connected to the side wall of the first mounting cylinder 21 and the second mounting cylinder 22. A limit block 210 is fixedly connected to one end of the rotating shaft 28. The limit block 210 is sleeved in the sleeve 29. A fixing screw 211 is installed on the sleeve 29 and the limit block 210. The mounting plate 27 on the left side is fixedly connected to the frame 1. A slide groove 213 is opened on the frame 1 on the right side. A first slider 214 is slidably connected in the slide groove 213. The mounting plate 27 on the right side is fixedly connected to the first slider 214. The mounting plate 27, rotating shaft 28, sleeve 29 and limiting block 210 work together to achieve reliable bearing and circumferential limiting of the mounting cylinder; the second mounting cylinder 22 can flexibly adjust the distance between the two mounting cylinders to adapt to different pipe lengths through the sliding cooperation of the first slider 214 and the slide groove 213; the fixing screw 211 provides a quick locking function so that the overall clamping mechanism remains rigidly fixed after adjustment, thereby ensuring the centering and processing rigidity when clamping long pipe fittings.

[0047] like Figures 1 to 5 As shown, a first motor 212 is installed at one end of the rotating shaft 28 that is mounted with the first limiting cylinder 21. The first motor 212 is used to drive the first limiting cylinder 21 to rotate, so as to drive the pipe fixed by the first limiting cylinder 21 and the second limiting cylinder 22 to rotate, thereby improving the processing efficiency and accuracy of the pipe through the rotation of the pipe.

[0048] like Figure 2 and Figure 7As shown, the drive unit includes a transverse drive unit and a longitudinal drive unit. The transverse drive unit includes a first mounting rail 32, a second slider 33, a first lead screw 34, and a second motor 35. The first mounting rail 32 is fixedly connected to the frame 1. The second slider 33 is slidably connected to the first mounting rail 32 in a left-right sliding manner. The first lead screw 34 is mounted inside the first mounting rail 32 in a left-right through-type and rotatable manner. The second slider 33 is threadedly connected to the first lead screw 34. The drive end of the second motor 35 is connected to one end of the first lead screw 34. The transverse drive unit drives the second slider 33 to move precisely left and right along the first mounting rail 32 via the first lead screw 34, providing transverse feed power to the machining tool 31 and realizing CNC positioning of the workpiece's transverse machining position. Its structure is compact and the transmission is smooth, providing basic motion guarantee for automated machining.

[0049] like Figure 2 and Figure 7 As shown, the longitudinal drive unit includes a first support plate 36, a second mounting rail 37, a third slider 38, a second lead screw 39, a third motor 310, and a second support plate 311. The first support plate 36 is fixedly connected to the second slider 33, the second mounting rail 37 is fixedly connected to the first support plate 36, the third slider 38 is slidably connected to the second mounting rail 37 in a back-and-forth sliding manner, the second lead screw 39 is installed in the second mounting rail 37 in a left-right through-hole and rotatable manner, the third slider 38 is threadedly connected to the second lead screw 39, the drive end of the third motor 310 is connected to one end of the second lead screw 39, the second support plate 311 is fixedly connected to the third slider 38, and the processing tool 31 is fixedly connected to the second support plate 311 in a detachable manner. The longitudinal drive unit drives the third slider 38 to move back and forth along the second mounting rail 37 via the second lead screw 39. Combined with the transverse drive unit, it realizes the precise positioning of the processing tool in the horizontal plane with two-axis linkage. The second support plate 311 facilitates the quick disassembly and replacement of the processing tool, enabling the device to adapt to various processing tasks such as cutting, beveling, and deburring, thereby improving the functionality and flexibility of the equipment.

[0050] like Figures 1 to 3 and Figure 8The cooling unit also includes a branch pipe 44 and a cooling medium delivery unit. The branch pipe 44 is located on one side of the annular cooling pipe 41. The gap between the annular cooling pipe 41 and the branch pipe 44 is used for machining the pipe fitting. A connecting pipe 43 is fixedly connected between the annular cooling pipe 41 and the branch pipe 44. Multiple second nozzles 45 are installed on the side wall of the branch pipe 44 in a downward-sloping manner facing the side wall of the annular cooling pipe 41. By adding the branch pipe 44 and connecting it to the annular cooling pipe 41 through the connecting pipe 43, a cooling channel network surrounding the machining area is formed, expanding the cooling coverage. At the same time, the cooling medium is sprayed onto the other side of the pipe fitting through the multiple second nozzles 45, achieving cooling of the pipe fitting and machining tools while also recycling and collecting machining debris to avoid environmental pollution. The cooling medium delivery unit provides cooling medium to this network, ensuring the formation of a continuous and uniform cooling mist field in the tool-workpiece contact area, effectively suppressing local high temperatures, and improving cooling efficiency and machining quality.

[0051] like Figure 3 and Figure 6 As shown, the cooling medium delivery unit includes a medium delivery pipe 46, a two-fluid mixing chamber 47, a coolant delivery pipe 48, a compressed air delivery pipe 410, a collection tank 412, and a delivery pump 414. The medium delivery pipe 46 is fixedly connected to the side wall of the annular cooling pipe 41. The two-fluid mixing chamber 47 is fixedly connected to the end of the medium delivery pipe 46 away from the annular cooling pipe 41. The coolant delivery pipe 48 is fixedly connected to the inlet of the two-fluid mixing chamber 47. A cooling medium delivery pump is installed on the coolant delivery pipe 48. The first regulating valve 49 and the compressed air delivery pipe 410 are fixedly connected to the air inlet of the dual-fluid mixing chamber 47. A second regulating valve 411 is installed on the compressed air delivery pipe 410. The liquid collection tank 412 is fixedly connected to the bottom of the frame 1. The delivery pump 414 is located on one side of the liquid collection tank 412. An inlet pipe 413 is fixedly connected between the delivery pump 414 and the liquid collection tank 412. The end of the coolant delivery pipe 48 away from the dual-fluid mixing chamber 47 is installed at the outlet of the delivery pump 414. The cooling medium delivery unit mixes and atomizes the coolant and compressed air through the dual-fluid mixing chamber 47 to form an aerosol cooling medium with better cooling effect. The first regulating valve 49 and the second regulating valve 411 can independently adjust the flow rate and ratio of coolant and air to achieve precise control of cooling intensity and mode. The system forms a closed loop with the liquid collection tank 412 and the delivery pump 414, which improves the utilization rate of the cooling medium and reduces consumption and cost.

[0052] like Figure 5 and Figure 9As shown, the chip removal unit includes multiple through holes 415, a mounting groove 416, a first filter screen 417, and a second filter screen 418. The multiple through holes 415 are arranged in an array and extend vertically through the frame 1. The mounting groove 416 is located on the frame 1 and above the multiple through holes 415. The first filter screen 417 is installed in the mounting groove 416, and the second filter screen 418 is detachably installed in the liquid collection tank 412. The chip removal unit collects falling debris and coolant through the through holes 415 on the frame 1, and performs preliminary solid-liquid separation using the first filter screen 417. The second filter screen 418 performs secondary filtration in the liquid collection tank 412 to ensure the cleanliness of the recovered coolant, effectively preventing pipe blockage and pump wear, and achieving a clean processing environment and coolant recycling.

[0053] like Figure 5 and Figure 7 As shown, a drain pipe 419 is fixedly connected to the bottom side wall of the collection tank 412, and a connecting rod 420 is fixedly connected to the first support plate 36. The other end of the connecting rod 420 is fixedly connected to the side wall of the annular cooling pipe 41. The drain pipe 419 is used to treat the microparticles deposited at the bottom of the collection tank 412; the connecting rod 420 rigidly connects the annular cooling pipe 41 to the first support plate 36, ensuring that the cooling unit maintains a stable position during processing vibration, thereby ensuring the positioning accuracy of the cooling spray. Under the action of the connecting rod 420, when the transverse drive unit drives the processing tool 31 to move laterally, the connecting rod 420 can drive the annular cooling pipe 41 to move synchronously, so that the processing tool 31 can efficiently cool the processing position when processing pipes at different positions.

[0054] In use, firstly, based on the diameter and length of the pipe to be processed, a suitable limiting cylinder 23 is quickly inserted into the first mounting cylinder 21 and the second mounting cylinder 22, and centering and clamping are completed through the sliding adjustment mechanism of the second mounting cylinder 22. During processing, the control system commands the horizontal and vertical drive units to work together, driving the processing tool 31 to move precisely to the set position for cutting or end face processing of the pipe. At the same time, the cooling medium delivery unit is activated, spraying atomized coolant precisely and evenly onto the contact area between the tool and the workpiece through the first nozzle 42 on the annular cooling pipe 41 and the second nozzle 45 on the branch pipe 44, achieving forced cooling and lubrication. The chips and coolant generated during processing fall through the through hole 415 on the frame 1, and are separated into solid and liquid by the multi-stage filtration and chip removal unit, with the clean coolant being recycled. The entire process realizes a fully integrated and automated operation of "adaptive clamping - CNC machining - synchronous precision cooling - automatic chip removal and recycling", effectively solving three major technical problems: poor versatility of pipe clamping, severe heat damage during processing, and low cleanliness of the working environment.

[0055] Another embodiment of the present invention provides a method for processing stainless steel pipes, comprising the following steps:

[0056] S1: According to the diameter of the stainless steel pipe to be processed, select the appropriate limiting cylinder 23 and install it into the first mounting cylinder 21 and the second mounting cylinder 22 respectively. Adjust the spacing of the limiting cylinder 23 by sliding the second mounting cylinder 22 to adapt to the pipe length. Then rotate the fixing screw 211 to lock the sleeve 29 and the limiting block 210 to complete the clamping and centering of the pipe fitting.

[0057] S2: The processing mechanism 3 is started by the control system. The horizontal drive unit and the vertical drive unit work together to move the processing tool 31 to the preset processing position to cut, bevele or deburr the stainless steel pipe.

[0058] S3: During the processing, the cooling medium delivery unit is activated, and the coolant and compressed air are mixed in the dual fluid mixing chamber 47 and then sprayed onto the contact area between the tool and the workpiece through the first nozzle 42 on the annular cooling pipe 41 and the second nozzle 45 on the branch pipe 44 for forced cooling.

[0059] S4: The debris and coolant generated during processing fall through the through hole 415 on the frame 1. After being initially filtered by the first filter screen 417, the coolant flows into the collection tank 412 and is further filtered by the second filter screen 418. It is then recycled by the delivery pump 414.

[0060] S5: After processing is completed, the processing mechanism 3 is reset, the clamping mechanism 2 is released, and the processed stainless steel pipe is removed.

[0061] The method claims systematically describe the complete process flow of stainless steel pipe processing using the aforementioned device, from clamping and adjustment, CNC machining, synchronous cooling, chip recycling to processing completion. Each step is closely related to the structure and function of the device, reflecting the integrated and automated working logic of the device in "clamping-machining-cooling-chip removal".
