Description

Technical Field

[0001] The invention relates to the field of pipe processing, in particular to a stainless steel pipe internal thread processing device. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel strip whose surface has been specially treated to resist oxidation and corrosion, thereby maintaining a rust-free state for a long time. Stainless steel pipe is widely used in industrial fields such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, etc. as a conveying pipeline and mechanical structural components due to its excellent corrosion resistance, high strength, good processing performance and beautiful appearance.

[0003] The processing flow of stainless steel pipes mainly includes the following steps: material preparation, forming, smelting and rolling, annealing, internal thread processing, finished product processing, surface treatment, finished product testing, packaging and delivery. Internal thread processing is one of the important steps in stainless steel pipe processing. Internal thread processing can ensure that the stainless steel pipe forms a tight connection with other pipe fittings, valves or equipment with external threads.

[0004] During the existing internal thread processing of stainless steel pipes, it is usually necessary to spray cutting fluid on the processing surface to clean the debris. During production and observation, it was found that when the cutting fluid is sprayed on the stainless steel surface, the cutting fluid entering the stainless steel pipe will carry the debris into the stainless steel, resulting in debris remaining inside the processed stainless steel pipe threads. It takes more working time to clean the inner wall of the stainless steel pipe, which makes the internal thread processing of the stainless steel pipe by the device more cumbersome.

After the electric push rod 104 is started, it will drive the fixing seat 105 to bring the first connecting tube 106 closer to the stainless steel pipe. When the first connecting tube 106 moves, it will bring the tool 111 along When the third connecting pipe 112 rotates, it will drive the second connecting pipe 108 and the liquid outlet pipe 109 to rotate together. When the cutting fluid flows inside the first connecting pipe 106, the auger 110 will rotate under the action of the water flow. When the auger 110 rotates, it will also drive the third connecting pipe 112 to rotate together. When the third connecting pipe 112 rotates, it will drive the second connecting pipe 108 and the liquid outlet pipe 109 to rotate together. When the cutting fluid flows inside the first connecting pipe 106, it will pass through the The cutting fluid enters the interior of the second connecting tube 108 through the third connecting tube 112, and then enters each liquid outlet pipe 109 through the second connecting tube 108 and sprays onto the inner wall of the stainless steel tube. Because the liquid outlet pipe 109 is located inside the stainless steel tube at this time, the cutting fluid will spray from the inside of the stainless steel tube to the outside. When the cutting fluid lubricates and cools the inner wall of the stainless steel tube, it will also remove the debris generated by the processing, so that the debris is discharged to the outside of the stainless steel tube together with the cutting fluid; after the cutting fluid enters the liquid outlet pipe 109 through the liquid inlet pipe 107, the debris will be flushed from the inside of the stainless steel tube to the outside, reducing the debris remaining inside the thread when the device processes the internal thread of the stainless steel tube, thereby improving the convenience of the device for cleaning the stainless steel tube.

[0034] See also Figure 4 and Figure 5As shown, a plurality of first elastic springs 2 are fixedly connected to the inner side wall of the first connecting tube 106; a first connecting plate 22 is fixedly connected to the end of the adjacent first elastic spring 2; a square plate 23 is fixedly connected to the top of the first connecting plate 22; the square plate 23 and the first connecting tube 106 are slidably connected and are arranged through; a plurality of first cleaning rods 24 are fixedly connected to the top of the square plate 23; when the cutting fluid flows inside the first connecting tube 106, the first connecting plate 22 will be affected by the water flow and slide along the first connecting tube 106. When the first connecting plate 22 moves, the first elastic spring 2 is in a stretched state. At the same time, the first connecting plate 22 will move with the square plate 23 and the first cleaning rod 24. When the first cleaning rod 24 moves, it will come into contact with the inner wall of the stainless steel pipe. Because the first cleaning rod 24 is made of flexible material, the first cleaning rod 24 will bend when rubbing against the inner wall of the stainless steel pipe and clean the inner wall of the stainless steel pipe. The first connecting plate 22 will make the first cleaning rod 24 approach the inner wall of the stainless steel pipe under the action of water flow and clean it, further improving the cleaning ability of the device on the inner wall of the stainless steel pipe, reducing debris attached to the inner wall of the stainless steel pipe, and reducing the impact of debris accumulated on the inner wall of the stainless steel pipe on the processing process.

[0035] See also Figure 4 and Figure 5 As shown, a plurality of first fixing slots 3 are provided in the middle of the first connecting tube 106; a plurality of first spring telescopic rods 32 are fixedly connected in the middle of the first fixing slots 3; a cross plate 33 is fixedly connected to the top of the adjacent first spring telescopic rods 32; a plurality of fixing holes 34 are provided in the middle of the cross plate 33; the fixing holes 34 and the first cleaning rod 24 are correspondingly arranged and slidably connected; when the first cleaning rod 24 slides along the first connecting tube 106 along with the first connecting plate 22, the first cleaning rod 24 will slide along the fixing holes 34 and rub against the fixing holes 34, and the fixing holes 34 will clean the debris attached to the surface of the first cleaning rod 24, so that the device can clean the first cleaning rod 24. At the same time, when the first cleaning rod 24 contacts the inner wall of the stainless steel pipe, the first cleaning rod 24 will be supported by the fixing holes 34 and the bending curvature is reduced, thereby increasing the contact area between the first cleaning rod 24 and the stainless steel pipe, thereby enhancing the cleaning effect of the first cleaning rod 24 on the stainless steel pipe.

[0036] See also Figure 3 and Figure 6As shown, a plurality of second spring telescopic rods 4 are fixedly connected to the middle of the fixing seat 105; the ends of the adjacent second spring telescopic rods 4 are fixedly connected to a second connecting plate 42; the middle of the second connecting plate 42 is fixedly connected to a hole plate 43; the first connecting pipe 106 is located inside the hole plate 43; the end of the hole plate 43 is fixedly connected to a first vertical plate 44; the middle of the first vertical plate 44 is fixedly connected to a plurality of second elastic springs 46; the ends of the adjacent second elastic springs 46 are fixedly connected to a second vertical plate 45; the middle of the second vertical plate 45 is rotatably connected to a plurality of first balls 47; when the fixing seat 105 moves toward the three-jaw chuck 103, it will also bring As the second spring telescopic rod 4 moves, the second spring telescopic rod 4 will move with the second connecting plate 42 and the orifice plate 43, and the orifice plate 43 will connect with the first vertical plate 44 and the second vertical plate 45 to approach the stainless steel pipe. When the second vertical plate 45 moves, it will come into contact with the outside of the three-jaw chuck 103. At this time, the stainless steel pipe will be inside the orifice plate 43. When the three-jaw chuck 103 rotates, the first ball 47 will also rotate under the action of friction, reducing the wear caused by friction between the three-jaw chuck 103 and the second vertical plate 45. At the same time, the debris splashed when the device processes the stainless steel pipe will be intercepted by the orifice plate 43, reducing the debris remaining on the surface of the device.

[0037] See also Figures 6 to 9As shown, a pair of slides 5 are fixedly connected to the middle part of the orifice plate 43; the slide 5 is an arc-shaped structure; a plurality of third spring telescopic rods 52 are fixedly connected to the middle part of the three-jaw chuck 103; the ends of the third spring telescopic rods 52 are fixedly connected to the third connecting plate 53; the middle part of the third connecting plate 53 is fixedly connected to a convex rod 54; the middle part of the third connecting plate 53 is fixedly connected to a plurality of second cleaning rods 55; when the second connecting plate 42 approaches the three-jaw chuck 103, the slide 5 will also move together, and the convex rod 54 will come into contact with the slide 5, because when the three-jaw chuck 103 rotates, the third spring telescopic rod 52, the third connecting plate 53 and the convex rod 54 will rotate together, and when the convex rod 54 rotates, it will slide along the surface of the slide 5, because the slide 5 is an arc-shaped structure, so that the convex rod 54 will carry the third connecting plate 53 to move along the second connecting plate 42, and when the third connecting plate 53 moves, the length of the third spring telescopic rod 52 will change The third connecting plate 53 will follow the protruding rod 54 to drive the second cleaning rod 55 to make reciprocating motion along the orifice plate 43 and enable the second cleaning rod 55 to dredge and clean the orifice plate 43, thereby realizing the cleaning of the orifice plate 43 by the device, ensuring that the orifice plate 43 can intercept debris and prolong the service life of the orifice plate 43.

[0038] See also Figure 7 As shown, a pair of second fixing grooves 6 are provided in the middle of the second connecting plate 42; a plurality of damping springs 62 are fixedly connected in the middle of the second fixing grooves 6; a baffle 63 is fixedly connected to the top of the adjacent damping springs 62; when the protruding rod 54 slides from the edge of the slide plate 5, it will be accelerated by the elastic force of the third spring telescopic rod 52, so that the protruding rod 54 will hit the surface of the second connecting plate 42, and when the protruding rod 54 moves, it will come into contact with the baffle 63 and hit the baffle 63. After the baffle 63 is impacted, the impact force will be transmitted to the damping spring 62, and the damping spring 62 will be rapidly compressed under the impact and absorb the impact energy during the compression process. Then the damping spring 62 will transmit the attenuated impact force to the second connecting plate 42, thereby reducing the impact on the second connecting plate 42 and extending the service life of the second connecting plate 42.

[0039] See also Figure 7As shown, a plurality of vertical rods 7 are fixedly connected to the middle part of the baffle 63; a plurality of third fixing slots 72 are opened in the middle part of the second fixing slot 6; the third fixing slots 72 and the vertical rod 7 are correspondingly arranged and slidingly matched; a plurality of flexible plates 73 are fixed to the middle part of the third fixing slot 72; when the baffle 63 is impacted, it will move toward the second fixing slot 6 as the damping spring 62 is compressed, and the baffle 63 will move with the vertical rod 7 when it moves. When the vertical rod 7 moves, it will enter the interior of the third fixing slot 72 and come into contact with the flexible plate 73. Because the flexible plate 73 is a flexible material, the surface friction coefficient is larger, so that the vertical rod 7 will be subjected to additional friction when sliding inside the third fixing slot 72, reducing the displacement amplitude of the vertical rod 7 and the baffle 63 when they are impacted. At the same time, the third fixing slot 72 can also fill the gap between the vertical rod 7 and the third fixing slot 72, reducing the shaking of the vertical rod 7 when it moves, and also reducing the shaking amplitude of the baffle 63 when it is impacted.

[0040] See also Figure 6 As shown, a plurality of guide plates 8 are fixedly connected to the middle part of the second vertical plate 45; the guide plates 8 are of an arc-shaped structure; when the second vertical plate 45 moves toward the three-jaw chuck 103, the guide plates 8 will come into contact with the surface of the stainless steel tube. Since the guide plates 8 are of an arc-shaped structure, the stainless steel tube will continue to come into contact with the surface of the guide plates 8 until the second vertical plate 45 comes into contact with the three-jaw chuck 103, thereby reducing the direct contact between the second vertical plate 45 and the stainless steel tube when it moves, and reducing the interference effect of the second vertical plate 45 on the fixation of the stainless steel tube.

[0041] See also Figure 6 As shown, the middle part of the guide plate 8 is rotatably connected with a plurality of second balls 9; the second balls 9 are located between the first connecting tube 106 and the second vertical plate 45; when the stainless steel tube and the guide plate 8 come into contact, they will also come into contact with the second balls 9, and the second balls 9 will rotate under the action of friction, so that the sliding friction between the stainless steel tube and the guide plate 8 is converted into rolling friction, thereby reducing the friction between the stainless steel tube and the guide plate 8 and reducing the scratches or damage on the surface of the stainless steel tube due to friction.

[0042] See also Figure 2 As shown, a collecting box 1001 is fixedly connected to the middle of the fixing seat 105; a filter pad 1002 is fixedly connected to the inner wall of the collecting box 1001; when the device processes the stainless steel pipe, the cutting waste liquid and the splashed debris will flow out from the surface of the second connecting plate 42, and these solid-liquid mixtures will reach the interior of the collecting box 1001 and be filtered by the filter pad 1002. The filter pad 1002 will filter the debris in the mixture, and the cutting waste liquid will reach the interior of the collecting box 1001, thereby realizing the separation and collection of the debris and the cutting waste liquid by the device, and improving the utilization rate of the device.

[0043] Working principle: The stainless steel pipe is put into the inside of the three-jaw chuck 103 and fixed, and then the starting device is started to start the electric push rod 104. After the electric push rod 104 is started, it will drive the fixing seat 105 to bring the first connecting pipe 106 closer to the stainless steel pipe. When the first connecting pipe 106 moves, it will move with the tool 111. At the same time, the power component 102 will rotate with the three-jaw chuck 103 and the stainless steel pipe. When the tool 111 comes into contact with the stainless steel pipe, the inner wall of the stainless steel pipe will be processed with internal threads. At the same time, the staff can connect the liquid inlet pipe 107 to an external water pump to allow the cutting fluid to flow from the liquid inlet pipe 107 to the first connecting pipe 1 06, when the cutting fluid flows inside the first connecting pipe 106, the auger 110 will rotate under the action of the water flow, and when the auger 110 rotates, it will also drive the third connecting pipe 112 to rotate together, and when the third connecting pipe 112 rotates, it will drive the second connecting pipe 108 and the liquid outlet pipe 109 to rotate together. When the cutting fluid flows inside the first connecting pipe 106, it will enter the interior of the second connecting pipe 108 through the third connecting pipe 112, and then enter each liquid outlet pipe 109 through the second connecting pipe 108 and spray on the inner wall of the stainless steel pipe. Because the liquid outlet pipe 109 is located inside the stainless steel pipe at this time, the cutting fluid will be discharged from the stainless steel pipe. When the cutting fluid lubricates and cools the inner wall of the stainless steel pipe, it also removes the debris generated by the processing, so that the debris is discharged to the outside of the stainless steel pipe together with the cutting fluid; when the cutting fluid flows inside the first connecting pipe 106, the first connecting plate 22 will be affected by the water flow and slide along the first connecting pipe 106. When the first connecting plate 22 moves, the first elastic spring 2 will be in a stretched state. At the same time, the first connecting plate 22 will move with the square plate 23 and the first cleaning rod 24. When the first cleaning rod 24 moves, it will come into contact with the inner wall of the stainless steel pipe. Because the first cleaning rod 24 is made of flexible material, the first cleaning rod 24 When the first cleaning rod 24 rubs against the inner wall of the stainless steel pipe, it bends and cleans the inner wall of the stainless steel pipe. When the first cleaning rod 24 slides along the first connecting pipe 106 along the first connecting plate 22, the first cleaning rod 24 slides along the fixing hole 34 and rubs against the fixing hole 34. The fixing hole 34 cleans the debris attached to the surface of the first cleaning rod 24, so that the device can clean the first cleaning rod 24. At the same time, when the first cleaning rod 24 contacts the inner wall of the stainless steel pipe, the first cleaning rod 24 is supported by the fixing hole 34 and the curvature of the bending is reduced, thereby increasing the contact area between the first cleaning rod 24 and the stainless steel pipe.When the fixed seat 105 moves toward the three-jaw chuck 103, it will also move with the second spring telescopic rod 4, and the second spring telescopic rod 4 will move with the second connecting plate 42 and the orifice plate 43. The orifice plate 43 will connect the first vertical plate 44 and the second vertical plate 45 and move closer to the stainless steel pipe. When the second vertical plate 45 moves, it will come into contact with the three-jaw chuck 103. At this time, the stainless steel pipe will be inside the orifice plate 43. When the device processes the stainless steel pipe, the flying debris will be intercepted by the orifice plate 43, reducing the debris remaining on the surface of the device. At the same time, when the tool 111 grinds the inner wall of the stainless steel pipe, it will shake slightly under the extrusion, and the force will be transmitted to the second connecting plate 4 through the first connecting pipe 106. 2 and the orifice plate 43, and then transmitted to the first vertical plate 44 and the second elastic spring 46. When the first vertical plate 44 shakes, the second elastic spring 46 will be in a bent state. The second elastic spring 46 will absorb this part of the kinetic energy, thereby reducing the shaking of the second vertical plate 45 when it is working; when the second connecting plate 42 approaches the three-jaw chuck 103, the slide plate 5 will also move together, and the protruding rod 54 will come into contact with the slide plate 5, because when the three-jaw chuck 103 rotates, it will drive the third spring telescopic rod 52 and the third connecting plate 53 and the protruding rod 54 to rotate together. When the protruding rod 54 rotates, it will slide along the surface of the slide plate 5. Because the slide plate 5 is an arc-shaped structure, the protruding rod 54 will bring the third connecting plate 53 together When the third connecting plate 53 moves along the second connecting plate 42, the length of the third spring telescopic rod 52 will change when the third connecting plate 53 moves. When the protruding rod 54 moves to the end of the slide plate 5, it will fall off the edge of the slide plate 5 and reach the surface of the second connecting plate 42. Then the protruding rod 54 will continue to slide along the surface of the second connecting plate 42 until it comes into contact with another slide plate 5 and repeats the action, so that the third connecting plate 53 will reciprocate with the protruding rod 54. When the third connecting plate 53 moves, it will move with the second cleaning rod 55. Because the second cleaning rod 55 is made of flexible material, the second cleaning rod 55 will bend when it comes into contact with the orifice plate 43, and the second cleaning rod 55 will press the orifice plate 43 when it comes into contact with the orifice plate 43. 3. The surface of the sled 54 is dredged and cleaned to reduce the debris accumulated inside the orifice plate 43. When the protruding rod 54 slides down from the edge of the slide plate 5, it is accelerated by the elastic force of the third spring telescopic rod 52, so that the protruding rod 54 will hit the surface of the second connecting plate 42. When the protruding rod 54 moves, it will come into contact with the baffle 63 and hit the baffle 63. After the baffle 63 is impacted, the impact force is transmitted to the damping spring 62. The damping spring 62 is quickly compressed under the impact and absorbs the impact energy during the compression process. Then, the damping spring 62 transmits the attenuated impact force to the second connecting plate 42, thereby reducing the impact on the second connecting plate 42 and extending the service life of the second connecting plate 42.When the second plate 45 moves toward the three-jaw chuck 103, the guide plate 8 will come into contact with the surface of the stainless steel pipe. Because the guide plate 8 is an arc structure, the stainless steel pipe will continue to contact the surface of the guide plate 8 until the second plate 45 and the three-jaw chuck are in contact. The disc 103 comes into contact with the second vertical plate 45, reducing direct contact between the second vertical plate 45 and the stainless steel tube when it moves, thereby reducing the interference of the second vertical plate 45 on the fixation of the stainless steel tube. When the stainless steel tube comes into contact with the guide plate 8, it also comes into contact with the second ball 9. Under the action of friction, the second ball 9 rotates, converting the sliding friction between the stainless steel tube and the guide plate 8 into rolling friction, reducing the friction between the stainless steel tube and the guide plate 8 and reducing scratches or damage on the surface of the stainless steel tube caused by friction. When the device processes the stainless steel tube, cutting waste liquid and splashing debris will flow out from the surface of the second connecting plate 42. This solid-liquid mixture will enter the interior of the collection box 1001 and be filtered by the filter pad 1002. The filter pad 1002 will filter the mixed debris, while the cutting waste liquid will enter the interior of the collection box 1001. This device can separate and collect the debris and cutting waste liquid, thereby improving the utilization rate of the device.
