Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment technology, specifically to a processing equipment and method for metal pipe production. Background Technology

[0002] In the metal pipe manufacturing industry, efficient and precise processing equipment is crucial for meeting market demands and improving product quality. Metal pipe processing equipment is mainly used for cutting and shaping metal raw materials to produce metal pipe products that meet specifications and performance requirements. The performance of this equipment directly affects the dimensional accuracy, surface quality, and production efficiency of the metal pipes, and it has wide applications in industries such as construction, machinery manufacturing, and chemicals.

[0003] However, traditional metal pipe processing equipment has some significant shortcomings. In terms of cutting efficiency and automation, manual clamping and cutting are typically required, which is not only labor-intensive but also cumbersome, resulting in low efficiency and failing to meet the demands of large-scale production. Regarding pipe diameter adaptability, most equipment uses fixed clamping devices, making it difficult to adapt to metal pipes of different diameters, limiting the equipment's versatility and practicality. Furthermore, during the cutting process, factors such as friction can easily cause the metal pipe to rotate, affecting cutting accuracy and stability, and potentially damaging the cutting equipment. Additionally, the equipment's heat dissipation and debris removal functions are weak, failing to effectively reduce the temperature of the cutting area and remove debris in a timely manner, easily leading to decreased cutting quality and equipment malfunction. In conclusion, traditional metal pipe processing equipment urgently needs improvement and innovation to enhance production efficiency, quality, and automation levels. Summary of the Invention

The two positioning rings are fixedly connected to each other, and the positioning rings are fixedly connected to the middle upper surface of the base plate.

[0010] Preferably, a second bearing ring is rotatably connected to the inner surface of the resistance ring, and a second drive wheel is rotatably connected to the bottom outer surface of the second bearing ring. The second drive wheel is fixedly sleeved on the output shaft of the motor. The output shaft of the motor is rotatably connected to the connecting shaft, and damping is provided between the connecting shaft and the output shaft of the motor.

[0011] Preferably, a pressure block is slidably connected to the inner surface of the second bearing ring, and a first mounting groove is formed on the outer surface of the pressure block. A rotating plate is rotatably connected inside the first mounting groove. The outer side of the rotating plate is arc-shaped, and a cutting blade is fixedly connected to the outer surface of the rotating plate. The cutting blade is initially set outside the first mounting groove.

[0012] Preferably, an elastic plate is fixedly connected to the inner surface of the rotating plate. The elastic plate is V-shaped. The side of the elastic plate away from the rotating plate is fixedly connected to the inner surface of the first mounting groove. A corrugated plate is fixedly connected to the outer end of the elastic plate. The corrugated plate is disposed in the first mounting groove.

[0013] Preferably, the outer surfaces of the two sides of the second bearing ring are provided with a second sliding groove, the second sliding groove is arc-shaped and passes through the second bearing ring, wherein the second bearing ring is slidably connected to the resistance ring through the second sliding groove, the rotating plate is provided with an air gathering groove inside, the air gathering groove is connected to the inner cavity of the elastic plate, and the outlet of the air gathering groove is located at the tail of the cutting blade.

[0014] Preferably, the inner surface of the pressure block is provided with a second mounting groove. There are two second mounting grooves symmetrically arranged on the same pressure block. The second mounting grooves are symmetrically arranged on both sides of the first mounting groove. A compression bladder is fixedly installed inside the second mounting groove.

[0015] Preferably, a pressure plate is fixedly connected to the outer surface of the compression bladder, the pressure plate is elastically slidably connected in the second mounting groove, and the outer end of the pressure plate is initially set outside the second mounting groove. A fitting roller is rotatably connected to the outer surface of the pressure plate.

[0016] Preferably, the outer surface of the resistance ring is fixedly connected to a plug ring, the inner surface of the positioning ring is provided with a pressure groove, the pressure groove is set as an annular shape, the plug ring is inserted into the pressure groove, the two outer surfaces of the plug ring are pressed and fitted with friction rings, the friction rings are symmetrically slidably connected in the pressure groove, and the pressure groove communicates with the internal cavity of the compression bladder.

[0017] A processing method for a processing equipment used in metal tube production includes the following steps:

[0018] S1. Insert the metal tube through the middle of the mounting ring on one side of the fixing mechanism, and pass it through the cutting mechanism until it exits from the middle of the mounting ring on the other side of the fixing mechanism;

[0019] S2. Start the motor, which drives the connecting shaft to rotate, causing the first drive wheel to rotate the first bearing ring. Under the limiting action of the first slide groove, the positioning clamp begins to retract inward until it is firmly attached to the outer surface of the metal tube. At this time, as the motor continues to rotate, the positioning clamp can no longer retract, and the output shaft of the motor begins to rotate relative to the connecting shaft.

[0020] S3. When the motor starts, it will simultaneously drive the second drive wheel to rotate. The second drive wheel will drive the second bearing ring to rotate. At this time, under the limiting action of the second slide groove, the pressure block will begin to shrink inward until the inner surface of the contact roller is in contact with the outer surface of the metal tube. As the motor continues to rotate, the pressure block can no longer shrink. The second slide groove will drive the resistance ring to rotate, causing the cutting edge that is pressed on the outer surface of the metal tube to start to rotate and cut until the metal tube is finally cut.

[0021] S4. The reverse drive motor disengages the fixing mechanism and the cutting mechanism from the metal tube, and the cut metal tube is removed. This cycle continues to cut the metal tube.

[0022] The end of the metal tube to be cut is inserted through the through hole of the mounting ring on one side, then passes through the cutting mechanism and exits through the through hole of the mounting ring on the other side. The motor is then started, causing its output shaft to rotate, which in turn causes the connecting shafts on both sides to rotate, thus causing the first drive wheel to rotate. The rotation of the first drive wheel drives the first bearing ring to rotate. The positioning clamp, which is slidably connected inside the first bearing ring, is connected to the mounting ring through the first groove. When the first bearing ring starts to rotate, it causes the positioning clamp to tighten inwards, ultimately firmly adhering to the outer surface of the metal tube, thus automatically fixing the metal tube. When the positioning clamp is firmly adhering to the outer surface of the metal tube, the first drive wheel can no longer rotate under the pressure. At this point, the motor's output shaft begins to rotate relative to the connecting shaft, driving the second drive wheel to continue rotating, forcing the cutting mechanism to continue working, thereby completing the cutting of the metal tube.

[0023] This invention provides a processing equipment and method for producing metal tubes. It has the following beneficial effects:

[0024] (I) This processing equipment and method for metal pipe production, by linking the fixing mechanism and the cutting mechanism, can automatically clamp and fix both sides of the metal pipe when cutting it, which greatly reduces the cutting process, improves the cutting smoothness, and also improves the cutting efficiency. By setting a movable and retractable positioning clamp, this equipment can be matched with metal pipes of different diameters, which also greatly improves the practicality of this equipment. When the second drive wheel rotates, it will drive the second bearing ring to rotate, forcing the pressure block to start to tighten synchronously, that is, the pressure block gradually approaches the metal pipe. When the pressure block contacts and adheres to the outer surface of the metal pipe, the pressure block cannot continue to retract due to the limiting effect of the second sliding groove, which in turn drives the resistance ring to start to rotate, so that the resistance ring and the second bearing ring rotate synchronously. The cutting blade in the first mounting groove on the pressure block is used to rotate and cut the metal pipe. That is, after automatically fixing the metal pipe, it can also automatically adapt to the diameter of the metal pipe and perform the cutting operation, further improving the automation level of this equipment.

[0025] (II) The processing equipment and method used for metal pipe production involves the following: When the pressure block approaches the metal pipe, the contact rollers come into contact with the metal pipe, and the contact rollers clamp and fix the two sides of the cutting part of the metal pipe. While achieving the positioning effect, the rotational characteristics of the contact rollers also reduce the friction between the pressure block and the metal pipe, thereby preventing the metal pipe from rotating during the cutting process and greatly improving the stability of the cutting process. At the same time, when the contact rollers and the metal pipe come into contact and are squeezed, the pressure plate is pressed into the No. 2 mounting groove under pressure, and the extrusion bladder is squeezed, causing the extrusion bladder to deliver its internal air pressure into the pressure groove. As the internal air pressure of the pressure groove increases, it will push the friction rings on both sides closer to each other, thereby greatly increasing the friction between the friction rings and the insertion rings. This ensures that the resistance rings themselves can always support stable operation, further improving the working stability of the equipment. At the same time, it also avoids the problem of high subsequent maintenance costs caused by the rapid decrease in friction due to traditional contact friction.

[0026] (III) The processing equipment and method used in metal pipe production, during the process of the contact roller contacting the outer surface of the metal pipe, also causes the tail of the cutting blade to contact the metal pipe first. Then, under the action of extrusion pressure, the tail of the cutting blade retracts into the first mounting groove along with the rotating plate until the cutting blade is in complete contact with the outer surface of the metal pipe. The elastic force provided by the elastic plate and the corrugated plate further increases the extrusion pressure of the cutting blade on the metal pipe, thereby ensuring a smooth cutting process. As the cutting progresses, the tail of the cutting blade gradually moves in and out of the first mounting groove. Even when the tail of the cutting blade automatically expands to match the larger wall thickness of the metal pipe, a smooth cutting process can still be maintained. At the same time, compared with commonly used rotary cutting methods... Cutting via a cutting gear significantly reduces the pressure on the cutting edge during operation, extending its service life. When the rotating plate moves into the first mounting slot under pressure, the elastic plate contracts, compressing its internal cavity and transferring the internal air pressure to the air-gathering groove inside the rotating plate. This pressure is then discharged through the tail of the cutting edge. Since the pressure on the cutting edge during operation is not constant, the air pressure in the air-gathering groove fluctuates, releasing pressure outwards at times. This not only helps cool the cutting area but also blows away debris, preventing cutting quality issues caused by blade misalignment during operation. Attached Figure Description

[0040] First embodiment: as follows Figures 1 to 10As shown, the present invention provides a technical solution: a processing equipment for metal pipe production, including a base plate 1, a motor 2 fixedly mounted on the upper surface of the middle part of the base plate 1, the motor 2 being a dual-axis motor 2, and further comprising:

[0047] An elastic plate 49 is fixedly connected to the inner surface of the rotating plate 47. The elastic plate 49 is V-shaped. The side of the elastic plate 49 away from the rotating plate 47 is fixedly connected to the inner surface of the first mounting groove 46. A corrugated plate 410 is fixedly connected to the outer end of the elastic plate 49. The corrugated plate 410 is set in the first mounting groove 46.

[0048] The outer surfaces of the two sides of the second bearing ring 43 are provided with second sliding grooves 411. The second sliding grooves 411 are arc-shaped and pass through the second bearing ring 43. The second bearing ring 43 is slidably connected to the resistance ring 42 through the second sliding grooves 411. The rotating plate 47 is provided with an air gathering groove 412.

[0050] A pressure plate 415 is fixedly connected to the outer surface of the compression bladder 414. The pressure plate 415 is elastically slidably connected in the second mounting groove 413, and the outer end of the pressure plate 415 is initially set on the outside of the second mounting groove 413.

The friction rings 419 are symmetrically slidably connected in the pressure groove 418. The pressure groove 418 is connected to the internal cavity of the compression bladder 414.

[0052] A processing method for a processing equipment used in metal tube production includes the following steps:

[0053] S1. Insert the metal tube through the middle of the mounting ring 31 on one side of the fixing mechanism 3, and through the cutting mechanism 4 until it is output from the middle of the mounting ring 31 on the other side of the fixing mechanism 3.

[0054] S2. Start motor 2, which drives the connecting shaft 34 to rotate, causing the first drive wheel 33 to drive the first bearing ring 32 to rotate. Under the limiting action of the first slide groove 36, the positioning clamp 35 begins to retract inward until it is firmly attached to the outer surface of the metal tube. At this time, as the motor 2 continues to rotate, the positioning clamp 35 can no longer retract, and the output shaft of the motor 2 begins to rotate relative to the connecting shaft 34.

[0055] S3. When motor 2 starts, it will simultaneously drive the second drive wheel 44 to rotate. The second drive wheel 44 drives the second bearing ring 43 to rotate. At this time, under the limiting action of the second slide groove 411, the pressure block 45 begins to shrink inward until the inner surface of its contact roller 416 is in contact with the outer surface of the metal tube. At this time, as motor 2 continues to rotate, the pressure block 45 can no longer shrink. The second slide groove 411 drives the resistance ring 42 to rotate, causing the cutting blade 48 pressed on the outer surface of the metal tube to start rotating and cutting until the metal tube is finally cut.

[0056] S4. Reverse drive motor 2 causes the fixing mechanism 3 and cutting mechanism 4 to disengage from the metal tube, and the cut metal tube is removed. This cycle is repeated to form a continuous cutting process.

[0057] During operation, the end of the metal tube to be cut is inserted through the through hole of the mounting ring 31 on one side, then passes through the cutting mechanism 4 and exits through the through hole of the mounting ring 31 on the other side. The motor 2 is then started, causing its output shaft to rotate, which in turn causes the connecting shafts 34 on both sides to rotate, thus causing the first drive wheel 33 to rotate. When the first drive wheel 33 rotates, it drives the first bearing ring 32 to rotate. The positioning clamp 35, which is slidably connected inside the first bearing ring 32, is connected to the mounting ring 31 through the first sliding groove 36. Therefore, when the first bearing ring 32 starts to rotate, it causes the positioning clamp 35 to tighten inwards, ultimately firmly adhering to the outer surface of the metal tube, thus automatically fixing the metal tube. When the positioning clamp 35 is firmly attached to the outer surface of the metal tube, the first drive wheel 33 cannot continue to rotate under the pressure. At this time, the output shaft of the motor 2 begins to rotate relative to the connecting shaft 34, thereby driving the second drive wheel 44 to rotate continuously, forcing the cutting mechanism 4 to continue working, thus completing the cutting of the metal tube. By linking the fixing mechanism 3 with the cutting mechanism 4, the two sides of the metal tube can be automatically clamped and fixed during the cutting process, greatly reducing the cutting process, improving the cutting smoothness, and also increasing the cutting efficiency. By setting the movable and retractable positioning clamp 35, this equipment can be matched with metal tubes of different diameters, which also greatly improves the practicality of the equipment. The second drive wheel 44 rotates... This will cause the second bearing ring 43 to rotate, forcing the pressure block 45 to begin to tighten synchronously. Ultimately, the pressure block 45 gradually approaches the metal tube. When the pressure block 45 contacts and adheres to the outer surface of the metal tube, it cannot continue to contract due to the limiting effect of the second sliding groove 411. This causes the resistance ring 42 to begin rotating, ensuring that the resistance ring 42 rotates synchronously with the second bearing ring 43. The cutting blade 48 in the first mounting groove 46 on the pressure block 45 then performs a rotary cut on the metal tube. This achieves automatic adaptation to the diameter of the metal tube after automatic fixing and cutting operation, further improving the automation level of the equipment. When the pressure block 45 approaches the metal tube, the contact roller 416 contacts the metal tube, ultimately achieving contact through the contact roller. The rollers 416 clamp and fix the metal tube on both sides of the cutting area. While achieving a positioning effect, the rotational characteristics of the rollers 416 also reduce the friction between the pressure block 45 and the metal tube, thereby preventing the metal tube from rotating during the cutting process and greatly improving the stability of the cutting process. At the same time, when the rollers 416 come into contact with and squeeze the metal tube, the pressure plate 415 is pressed into the second mounting groove 413 under pressure, and squeezes the compression bladder 414, causing the compression bladder 414 to transfer its internal air pressure into the pressure groove 418. As the internal air pressure of the pressure groove 418 increases, it pushes the friction rings 419 on both sides closer together, thus greatly increasing the friction between the friction rings 419 and the insertion ring 417.This ensures that the resistance ring 42's own resistance can always support stable operation, further improving the working stability of the equipment. It also avoids the problem of high maintenance costs caused by the rapid decrease in friction due to traditional contact friction methods, which often require frequent repairs. During the contact between the roller 416 and the outer surface of the metal tube, the tail of the cutting blade 48 first contacts the metal tube. Then, under the pressure, the tail of the cutting blade 48 retracts into the first mounting slot 46 along with the rotating plate 47 until the cutting blade 48 is in complete contact with the outer surface of the metal tube. The elasticity provided by the elastic plate 49 and the corrugated plate 410 further increases the pressure of the cutting blade 48 on the metal tube, ensuring a smooth cutting process. As cutting progresses, the tail of the cutting blade 48 gradually moves in and out of the first mounting slot 46, allowing the tail of the cutting blade 48 to automatically expand to match the metal tube. Even with thicker walls, the cutting process remains smooth. Furthermore, compared to the commonly used gear-based cutting method, the rotary cutting significantly reduces the pressure on the cutting edge 48 during operation, resulting in a longer service life. When the rotating plate 47 moves into the first mounting slot 46 under pressure, the elastic plate 49 contracts, compressing its internal cavity and transferring the internal air pressure to the air-gathering groove 412 inside the rotating plate 47. This pressure is then discharged through the tail of the cutting edge 48. Since the pressure on the cutting edge 48 during operation is not constant, the pressure in the air-gathering groove 412 fluctuates, releasing pressure outwards at times. This not only helps cool the cutting area but also removes debris, preventing cutting quality issues caused by the cutting edge 48 shifting during operation.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
