Description

Technical Field

[0001] The present invention relates to the technical field of seamless steel pipe processing devices, and in particular to a high-precision seamless steel pipe automatic processing equipment. Background Technique

[0002] A steel pipe made of a whole piece of metal without seams on the surface is called a seamless steel pipe. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, pipe jacking pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and special-shaped. Special-shaped pipes have various complex shapes such as square, oval, triangular, hexagonal, melon seed-shaped, star-shaped, and finned pipes. Seamless steel pipes are mainly used as oil geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] After retrieval, it is found that the prior art publication number is CN111299686B, which discloses an automatic processing equipment for stainless steel seamless steel pipes, belonging to the technical field of seamless steel pipe processing. It includes a support plate, the upper surface of the support plate is fixedly connected to the lower surface of the support plate, the lower surface of the inner wall of the support plate is lapped with the bottom of the steel pipe body, the top of the steel pipe body is lapped with the upper surface of the inner wall of the pressing plate, the upper surface of the pressing plate is fixedly connected to the upper surface of the inner wall of the top plate through an electric hydraulic rod, the lower surface of the top plate is fixedly connected to the upper surface of the support plate, and two first bearings are clamped on the left side surface of the top plate. This scheme can cut the two ends of the steel pipe body simultaneously by setting a motor, a rotating shaft, a threaded column, a connecting block, a cutting machine, and an electric push rod, and can quickly cut the whole steel pipe body.

[0004] Therefore, based on the above retrieval and in combination with the existing technology, in the prior art, when using a cutting tool to cut a steel pipe, if the wall thickness of the steel pipe is relatively large, the cutting tool will encounter relatively large resistance during direct cutting. The high temperature generated during the cutting process may cause local deformation of the steel pipe, change in material properties, or generate thermal stress, which may in turn cause more burrs to appear on the cutting edge and even trigger microcracks, thus affecting subsequent processing or use. During the cutting process of using a cutting tool to cut a relatively thick steel pipe, the tool may crack, affecting production safety. For this reason, we propose a high-precision seamless steel pipe automatic processing equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-precision seamless steel pipe automatic processing equipment to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: An automated processing device for high-precision seamless steel pipes, including a frame. Inside the frame, there are multiple brackets for lifting the steel pipes. At the inner bottom end of the frame, there are multiple lifting electric push rods, and the telescopic ends of the lifting electric push rods are fixedly connected to the brackets. A sliding plate is slidably connected to the upper end of the frame. One end of the sliding plate close to the frame is provided with a collar. Inside the collar, there is a cutting device for cutting the steel pipe. An activity frame is slidably connected to the inner end of the frame, and inside the activity frame, there is a grinding device for grinding the outer surface of the steel pipe.

The output shaft of the driving motor is connected to the contact disc.

[0007] As a further aspect of the present invention, the cutting device includes a rotating ring. The rotating ring is rotatably connected to the outer surface of the collar. The inner end of the collar is rotatably connected to two arc plates through a rotating shaft. The inner ends of the two arc plates are respectively rotatably connected to a support wheel and a cooling wheel. A cutting wire is tensioned and sleeved between the support wheel and the cooling wheel. At the end of the arc plate close to the collar, there are cutting motors. The output shafts of the cutting motors are fixedly connected to the cooling wheel.

[0008] As a further aspect of the present invention, a liquid infusion pump is provided at the left end of the arc plate, and the liquid infusion pump is sleeved on the outer surface of the output shaft of the cutting motor. Inside the liquid infusion pump, there is a vortex fan, and the vortex fan is fixedly sleeved on the outer surface of the output shaft of the cutting motor. Two liquid cylinders are provided at the inner end of the collar through a clamp. The output end of the liquid cylinder is connected to the input end of the liquid infusion pump through a liquid infusion pipe.

[0009] As a further aspect of the present invention, a plurality of liquid seepage holes are opened at the inner end of the cooling wheel, and the liquid seepage holes extend to the outer surface of the cooling wheel. The output end of the vortex fan corresponds to the liquid seepage holes at the inner end of the cooling wheel. When the vortex fan rotates, the coolant in the liquid cylinder is transported through the liquid infusion pipe to the liquid seepage holes of the cooling wheel, which can ensure that the coolant evenly penetrates the surface of the cooling wheel, improve the cooling efficiency, and at the same time reduce the risk of local overheating.

[0010] As a further aspect of the present invention, a compression cylinder is fixedly installed at the upper end of the sliding plate. A screw rod passes through the inner end of the compression cylinder. One end of the screw rod away from the compression cylinder is provided with a traction wire, and the free end of the traction wire is fixedly connected to the outer surface of the rotating ring. A toothed ring is fixedly installed at the inner end of the rotating ring. A gear is fixedly installed at the end of the arc plate close to the rotating ring, and the gear meshes with the toothed ring. When the rotating ring rotates, it drives the arc plate to rotate, so as to realize that the cutting wire can fit more closely to the outer surface of the steel pipe to cut it.

[0011] As a further solution of the present invention, a pushing spring is sleeved on the outer surface of the screw rod. An adjusting sleeve is penetrated through the inner end of the compression cylinder. The adjusting sleeve is sleeved on the outer surface of the screw rod, and the left end of the pushing spring abuts against the right end of the adjusting sleeve, so that the pushing spring can provide a stable elastic effect when sleeved on the outer surface of the screw rod.

[0012] As a further solution of the present invention, the grinding device includes a driving wheel. The driving wheel is rotatably connected to the left end of the movable frame. A grinding motor is fixedly installed at the upper end of the movable frame. Tension wheels are fixedly installed on the outer surfaces of the rotating shafts of the grinding motor and the driving wheel, and a transmission belt is tensioned and sleeved between the two tension wheels. Two extension frames are arranged at the left end of the movable frame. Support cylinders are fixedly installed at the ends of the two extension frames away from the movable frame. Support sleeves are sleeved on the left and right ends of the support cylinder, and a grinding sand belt is tensioned and sleeved between the driving wheel and the support sleeve.

[0013] As a further solution of the present invention, a plurality of tensioning plates are rotatably connected to the left and right ends of the support cylinder. The tensioning plates are arranged in a ring shape, and the outer surface of the tensioning plate contacts the inner wall of the support sleeve. Pushing plates are arranged at the left and right ends of the support cylinder. By arranging a plurality of tensioning plates and arranging them in a ring shape, the tension of the grinding sand belt can be evenly distributed, avoiding the deviation or jitter of the grinding sand belt during high-speed operation, thereby improving the stability and precision of the grinding process.

[0014] As a further solution of the present invention, the outer surface of the pushing plate fits with the inner walls of the plurality of tensioning plates. Triangular blocks are fixedly installed on the inner walls of the tensioning plates. The outer surface of the pushing plate is chamfered. When the pushing plate moves away from the support cylinder, after contacting the inclined plane of the triangular block, by driving a plurality of tensioning plates to rotate outward, the working range of the tensioning plates is effectively expanded, realizing more stable clamping or releasing of the target component, and improving the adaptability and operation convenience of the device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention is used, by precisely adjusting the position and tension of the cutting wire and combining with the continuous rotation of the steel pipe, high-precision and high-stability circular cutting is achieved, thereby improving the cutting precision and quality, preventing the cutting wire from breaking, enhancing the automation degree of the equipment, reducing the maintenance cost, meeting the cutting requirements of steel pipes of different specifications, and improving the working environment at the same time; 2. When the present invention is used, through the coordinated action of the air pump, the movable plug and the pushing plate, automatic chamfering treatment after the steel pipe is cut is realized, thereby improving the chamfering precision and surface finish, reducing manual intervention, adapting to steel pipes of different specifications, reducing equipment wear, improving the working environment, and quickly switching the processing mode, thus significantly improving the processing efficiency and quality; 3.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1 - Figure 3 , a high-precision seamless steel pipe automatic processing device, including a frame 1.

A plurality of lifting electric push rods 101 are fixedly connected to the inner bottom end of the frame 1 through bolts, and the telescopic ends of the lifting electric push rods 101 are fixedly connected to the brackets 102 through bolts. After the steel pipe is placed above the brackets 102 from the lower area, the lifting electric push rods 101 lift the steel pipe to the working height, eliminating the need for manual lifting and thus avoiding the occurrence of falling accidents. A sliding plate 301 is slidably connected to the upper end of the frame 1. A collar 3 is fixedly connected to one end of the sliding plate 301 close to the frame 1. A cutting device for cutting the steel pipe is arranged inside the collar 3.

Driven by the telescopic end of the stable electric push rod 204, the integration plate 2 can move left and right on the upper end of the frame 1. The left end of the support shaft 201 is rotatably connected with an adjustment disk 203. The left end of the adjustment disk 203 is provided with a support frame 206, and the support frame 206 is fixedly welded to the support shaft 201; A plurality of expansion plates 202 are slidably connected to the outer surface of the support shaft 201. The expansion plates 202 are arranged in a ring shape, and the outer surface is arc-shaped and chamfered to avoid scratching the outer wall (or inner wall) of the steel pipe. The left end of the adjustment disk 203 is fixedly welded with a threaded disk 205. One end of the plurality of expansion plates 202 close to the adjustment disk 203 is provided with a threaded groove, and the threaded groove is connected to the threaded disk 205. Rotating the adjustment disk 203 drives the threaded disk 205 to rotate, so that the expansion plates 202 expand outwards or gather towards the center of the circle under the rotation of the threaded disk 205, so as to match steel pipes of different sizes.

[0021] Example 2: Please refer to Figure 1 , Figure 4 - Figure 7 , a high-precision seamless steel pipe automatic processing device, which is different from that of Example 1 in that the cutting device includes a rotating ring 304. The rotating ring 304 is rotatably connected to the outer surface of the collar 3. The inner end of the collar 3 is rotatably connected with two arc plates 308 by a rotating shaft. The inner ends of the two arc plates 308 are respectively rotatably connected with a support wheel 311 and a cooling wheel 313. Specifically, there are two support wheels 311, one is located at the end of the arc plate 308, and the other is located at the center of the arc plate 308. A cutting wire 306 is tensioned and sleeved between the support wheel 311 and the cooling wheel 313. The cutting wire 306 is made of alloy steel wire to meet the strength required for cutting the steel pipe. One end of the arc plate 308 close to the collar 3 is fixedly connected with a cutting motor 309, and the output shaft of the cutting motor 309 is fixedly connected with the cooling wheel 313; As Figure 6As shown in the figure, the left end of the arc plate 308 is fixedly connected to an infusion pump 312, and the infusion pump 312 is sleeved on the outer surface of the output shaft of the cutting motor 309. The inner end of the infusion pump 312 is provided with a vortex fan 314, and the vortex fan 314 is fixedly sleeved on the outer surface of the output shaft of the cutting motor 309. The inner end of the collar 3 is fixedly connected to two liquid cylinders 307 through a clamp. The output end of the liquid cylinder 307 is connected to the input end of the infusion pump 312 through an infusion tube 310. Specifically, a liquid supply system is provided inside the frame 1 for continuously supplying liquid to the liquid cylinder 307. This liquid supply system is a conventional configuration in the machining field, and its working principle is the same as that of a common industrial liquid supply system, mainly including functions such as liquid storage, pressure transmission, flow control, and circulation filtration to ensure stable and uniform liquid supply in the liquid cylinder 307. The specific working principle will not be elaborated here; A plurality of liquid seepage holes 315 are opened at the inner end of the cooling wheel 313, and the liquid seepage holes 315 extend to the outer surface of the cooling wheel 313 (i.e., the outer surface in contact with the cutting wire 306). The output end of the vortex fan 314 corresponds to the liquid seepage holes 315 at the inner end of the cooling wheel 313. When the vortex fan 314 rotates, the coolant inside the liquid cylinder 307 is pumped into the infusion pump 312 through the infusion tube 310, and then sprays out from the output end of the infusion pump 312 and submerges in the liquid seepage holes 315 inside the cooling wheel 313. Under the action of pressure, the coolant flows into the liquid seepage holes 315 and cools the cutting wire 306.

[0022] As Figure 4 , Figure 5 , Figure 8 As shown in the figure, a compression cylinder 302 is fixedly installed at the upper end of the sliding plate 301 through bolts. A screw rod 404 passes through the inner end of the compression cylinder 302. One end of the screw rod 404 away from the compression cylinder 302 is fixedly connected to a traction wire 303, and the free end of the traction wire 303 is fixedly connected to the outer surface of the rotating ring 304. Specifically, an auxiliary wheel 305 is rotatably installed at the upper end of the sliding plate 301, and the outer surface of the traction wire 303 is in contact with the outer surface of the auxiliary wheel 305. A toothed ring is fixedly installed at the inner end of the rotating ring 304, and a gear is fixedly installed at one end of the arc plate 308 close to the rotating ring 304. The gear meshes with the toothed ring. When the rotating ring 304 rotates, it drives the arc plate 308 to rotate, thereby enabling the cutting wire 306 to fit more closely to the outer surface of the steel pipe to achieve cutting; A driving spring 403 is sleeved on the outer surface of the screw rod 404. Specifically, a rectangular groove is formed on the outer surface of the screw rod 404, and a rectangular block is fixedly installed at the inner end of the compression cylinder 302. The rectangular block penetrates inside the rectangular groove, enabling the screw rod 404 to only move left and right and preventing self-rotation. An adjusting sleeve 401 penetrates through the inner end of the compression cylinder 302. The adjusting sleeve 401 is sleeved on the outer surface of the screw rod 404, and the left end of the driving spring 403 abuts against the right end of the adjusting sleeve 401. When the adjusting sleeve 401 rotates, it can move left and right on the outer surface of the screw rod 404. When moving towards the right, the driving spring 403 is compressed by a certain distance. A limiting ring is fixedly installed at the inner end of the compression cylinder 302, and a contact ring is fixedly sleeved on the outer surface of the adjusting sleeve 401. When the adjusting sleeve 401 moves a certain distance to the right, the driving spring 403 will push the adjusting sleeve 401 to move left during the reset process, thereby releasing a longer stroke distance; As Figure 9 shown, a passive ring 405 is slidably connected to the outer surface of the compression cylinder 302. The inner end of the passive ring 405 is fixedly connected to the outer surface of the compression cylinder 302. A passive wheel 402 is rotatably connected to the upper end of the passive ring 405. An anti-slip groove is fixedly installed at the upper end of the compression cylinder 302. An anti-slip rubber sleeve is fixedly sleeved on the outer surface of the passive wheel 402 and is closely fitted in the anti-slip groove at the upper end of the compression cylinder 302. When the passive ring 405 moves left and right on the outer surface of the compression cylinder 302, the passive wheel 402 starts to rotate at this time. A clamping ring 406 is fixedly installed at the upper end of the passive ring 405. A plurality of card slots are formed on the outer surface of the clamping ring 406, and the clamping ring 406 penetrates inside the passive wheel 402. A support plate 408 is fixedly installed at the inner end of the passive wheel 402, and a plurality of movable blocks 407 are slidably installed at the inner end of the support plate 408. The movable blocks 407 and the support plate 408 are connected by micro-motion springs. When the passive wheel 402 rotates too fast, the movable blocks 407 are thrown out under the action of inertia and are clamped on the outer surface of the clamping ring 406.

[0023] Example 3: Please refer to Figure 1 、 Figure 10 - Figure 12 A high-precision seamless steel pipe automatic processing device, which is different from that in Example 1 in that the grinding device includes a driving wheel 503. The driving wheel 503 is rotatably connected to the left end of the movable frame 4. A grinding motor 501 is fixedly installed at the upper end of the movable frame 4 through bolts, and tensioning wheels are fixedly installed on the outer surfaces of the rotating shafts of the grinding motor 501 and the driving wheel 503, and the two tensioning wheels are tightly sleeved by a transmission belt 502. Two extension frames 507 are arranged at the left end of the movable frame 4. Support cylinders 512 are fixedly installed at the ends of the two extension frames 507 far away from the movable frame 4. Support sleeves 509 are sleeved on the left and right ends of the support cylinders 512, and the driving wheel 503 and the support sleeve 509 are tightly sleeved by a grinding sand belt 504; Specifically, the inner end of the movable frame 4 is rotatably connected with an adjusting handle 506. A locking bolt is sleeved on the outer surface of the adjusting handle 506 in a threaded manner. An arc-shaped hole is formed on the outer surface of the movable frame 4. The locking bolt is inserted into the arc-shaped hole. After the adjusting handle 506 rotates at any angle, it can be fixed at the current angle through the locking bolt. Among the two extension frames 507, the lower one is fixedly connected with the movable frame 4, and the upper extension frame 507 is fixedly connected with the adjusting handle 506, so as to control the tension degree of the grinding sand belt 504 or be able to sleeve grinding sand belts 504 with different circumferences.

[0024] A plurality of tension plates 511 are rotatably connected to both the left and right ends of the support cylinder 512. The tension plates 511 are arranged in a ring shape, and the outer surface of the tension plates 511 contacts the inner wall of the support sleeve 509. Specifically, a plurality of round holes are formed on the outer surface of the tension plates 511, and balls are inserted into the round holes respectively to further reduce the friction with the support sleeve 509. Push plates 510 are arranged at both the left and right ends of the support cylinder 512, and the outer surface of the push plates 510 fits with the inner walls of the plurality of tension plates 511. Triangular blocks are fixedly installed on the inner walls of the tension plates 511, and chamfers are made on the outer surfaces of the push plates 510. When the push plates 510 move away from the support cylinder 512, after contacting the inclined plane of the triangular blocks, the plurality of tension plates 511 are driven to rotate outward, and the outer surface of the grinding sand belt 504 is bent accordingly, so that it can fit the edge part of the steel pipe, enabling the grinding sand belt 504 to efficiently chamfer the edge of the steel pipe, ensuring the accuracy of the chamfer and the surface finish, and improving the processing efficiency at the same time. An activity plug 513 is slidably connected to the inner end of the support cylinder 512. Both the left and right ends of the activity plug 513 are fixedly connected with the two push plates 510 through driving rods. The activity plug 513 divides the interior of the support cylinder 512 into left and right two chambers. An air pump 505 is fixedly installed at the upper end of the movable frame 4 through bolts. The air pump 505 has the functions of discharging air and inhaling air. The output end of the air pump 505 is fixedly connected with an air delivery pipe 508. The output end of the air delivery pipe 508 is divided into two sub-pipes and is respectively communicated with the left and right two chambers of the support cylinder 512. Specifically, the air delivery pipe 508 is connected with the two sub-pipes through an electromagnetic reversing valve for switching the air flow direction.

[0025] The working principle of the present invention is: During use, the steel pipe is placed above the bracket 102 from the lower area. Subsequently, the electric push rod 101 is lifted to raise the steel pipe to the working height. Then, the adjusting disc 203 is rotated according to the inner diameter of the steel pipe so that the distance between the expansion plates 202 can adapt to the inner diameter of the currently processed steel pipe. Then, under the pushing action of the output end of the stable electric push rod 204, the integration plate 2 is pushed to move. At this time, the steel pipe passes through the inside of the collar 3. Then, the adjusting disc 203 is continuously rotated to clamp the steel pipe and clamp it between the abutting disc 103 and the adjusting disc 203. Then, the driving motor 6 drives the abutting disc 103 to rotate at a low speed. Then, the grinding motor 501 drives the grinding sand belt 504 to rotate through the transmission belt 502, and under the driving action of the adjusting motor 5, the movable frame 4 can move left and right at the upper end of the frame 1 to realize grinding of the outer surface of the steel pipe; Subsequently, the sliding plate 301 is pushed to move to the area where the steel pipe needs to be cut, and the adjusting sleeve 401 starts to move by pushing the passive ring 405, and the spring 403 is pushed to compress. The output end of the cutting motor 309 drives the cooling wheel 313 to rotate, thereby driving the cutting wire 306 to rotate. At this time, the spring 403 is pushed to release its elastic force, and the traction wire 303 is pulled through the screw 404, causing the rotating ring 304 to rotate. Subsequently, the arc plate 308 also starts to rotate through the meshing of the gear and the toothed ring. By adjusting the position of the cutting wire 306, it can fit more closely to the outer surface of the steel pipe. Since the steel pipe rotates continuously during the cutting process, the cutting wire 306 can perform circular cutting along the outer surface of the steel pipe, effectively avoiding the situation where the cutting wire 306 cuts into the inside of the steel pipe, thereby preventing the cutting wire 306 from breaking due to excessive stress, and at the same time ensuring the stability of the cutting process and the cutting quality; Subsequently, after the steel pipe is cut off, the telescopic end of the stable electric push rod 204 drives the integration plate 2 to move to the right, and the steel pipe is thus divided into two. The output end of the air pump 505 fills a chamber in the support cylinder 512 with gas through the air pipe 508. At this time, the movable plug 513 starts to move, causing the push plate 510 to move away from the support cylinder 512 and contact the inclined plane of the triangular block. The push plate 510 squeezes and pushes a plurality of tension plates 511 to rotate outward, and the outer surface of the grinding sand belt 504 is bent accordingly, so that it can fit the edge part of the steel pipe, enabling the grinding sand belt 504 to efficiently chamfer the edge of the steel pipe, ensuring the accuracy of the chamfer and the surface finish, and at the same time improving the processing efficiency; After the processing is completed, the sliding plate 301 is moved to the edge position above the frame 1. Subsequently, the lifting electric push rod 101 is started to drive the bracket 102 to move downward, so that the processed steel pipe slowly descends to a low position, facilitating the operator to carry and transfer it. At the same time, the safety hazard during the handling process is reduced, and the operation efficiency and work safety are improved.

[0026] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
