Description

Technical Field

[0001] The invention relates to the technical field of pipe processing equipment, in particular to a processing equipment and a processing method for metal pipe production. Background Art

[0002] In the field of metal tube production, efficient and accurate processing equipment is essential to meet market demand and improve product quality. Metal tube processing equipment is mainly used to cut and shape metal raw materials to produce metal tube products that meet specifications and performance requirements. The performance of these equipment directly affects the dimensional accuracy, surface quality and production efficiency of metal tubes, and is widely used in construction, machinery manufacturing, chemical industry and other industries.

[0003] However, traditional metal tube processing equipment has some obvious shortcomings. In terms of cutting efficiency and automation, manual clamping and cutting are usually required, which is not only labor-intensive, but also cumbersome in the cutting process, resulting in low cutting efficiency and unable to meet the needs of large-scale production. In terms of pipe diameter adaptability, the clamping devices of most equipment are fixed and unchanged, making it difficult to adapt to metal pipes of different diameters, limiting the versatility and practicality of the equipment. In addition, during the cutting process, due to the influence of factors such as friction, the metal pipe is prone to self-rotation, affecting the cutting accuracy and stability, and may also cause damage to the cutting equipment. In addition, the heat dissipation and debris cleaning functions of the equipment are weak, and it is impossible to effectively reduce the temperature of the cutting part and remove the debris in a timely manner, which can easily lead to reduced cutting quality and equipment failure. In summary, traditional metal tube processing equipment is in urgent need of improvement and innovation to improve production efficiency, quality and automation level. Summary of the invention

[0014] A processing method for a processing device for producing a metal pipe comprises the following steps: S1. Insert the metal tube from the middle of the mounting ring on the fixing mechanism on one side, and pass through the cutting mechanism until it is output from the middle of the mounting ring on the fixing mechanism on the other side; S2, start the motor, drive the connecting shaft to rotate through the motor, and drive the No. 1 bearing ring to rotate through the No. 1 driving wheel. Under the limiting action of the No. 1 slide slot, the positioning clamp starts to shrink inward until it is firmly attached to the outer surface of the metal pipe. At this time, as the motor continues to rotate, the positioning clamp cannot continue to shrink, and the output shaft of the motor starts to rotate relative to the connecting shaft; S3, when the motor is started, it will drive the No. 2 driving wheel to rotate, and the No. 2 bearing ring will rotate through the No. 2 driving wheel. At this time, the pressure block starts to shrink inward under the limiting effect of the No. 2 slide slot, until the fitting roller on its inner surface fits the outer surface of the metal tube. At this time, as the motor continues to rotate, the pressure block cannot continue to shrink, and the resistance ring is driven to rotate through the No. 2 slide slot, so that the cutting blade accumulated on the outer surface of the metal tube starts to rotate and cut, until the metal tube is finally cut; S4, reverse driving the motor to make the fixing mechanism and the cutting mechanism break away from the contact with the metal pipe, and take out the cut metal pipe, and this cycle forms continuous cutting.

[0015] The end of the metal pipe to be cut is inserted into the through hole of the mounting ring on one side, then passes through the cutting mechanism and comes out from the through hole of the mounting ring on the other side, and then the motor can be started. When the motor is started, its output shaft will start to rotate, thereby prompting the connecting shafts on both sides to start to rotate, and then the No. 1 driving wheel will start to rotate. When the No. 1 driving wheel starts to rotate, it will drive the No. 1 bearing ring to start rotating, and the positioning clamp block slidingly connected in the No. 1 bearing ring is connected to the mounting ring through the No. 1 slide groove, that is, when the No. 1 bearing ring starts to rotate, the positioning clamp block will be tightened inwardly, and finally firmly fit on the outer surface of the metal pipe, thereby automatically completing the fixation of the metal pipe, and when the positioning clamp block is firmly fitted on the outer surface of the metal pipe, the No. 1 driving wheel cannot continue to rotate under the action of the extrusion force, and at this time the output shaft of the motor begins to make relative rotational motion relative to the connecting shaft, thereby driving the No. 2 driving wheel to rotate continuously, forcing the cutting mechanism to continue working, thereby completing the cutting of the metal pipe.

[0016] The present invention provides a processing device and a processing method for metal pipe production, which have the following beneficial effects: (I) The processing equipment and processing method for metal pipe production can automatically clamp and fix the two sides of the metal pipe when cutting the metal pipe by linking the fixing mechanism with the cutting mechanism, which greatly reduces the cutting process, improves the cutting fluency, and also improves the cutting efficiency. By setting a movable and retractable positioning clamp, the equipment can match metal pipes of different diameters, which also greatly improves the practicality of the equipment. When the No. 2 driving wheel rotates, it will drive the No. 2 bearing ring to rotate, forcing the pressure block to start to tighten synchronously, that is, finally making the pressure block gradually approach the metal pipe. When the pressure block contacts and fits the outer surface of the metal pipe, the pressure block cannot continue to shrink due to the limiting effect of the No. 2 slide groove, and then drives the resistance ring to start rotating, that is, the resistance ring and the No. 2 bearing ring rotate synchronously, and the cutting blade in the No. 1 mounting groove on the pressure block is used to perform rotational cutting on the metal pipe, that is, after the metal pipe is automatically fixed, it also automatically adapts to the diameter of the metal pipe and performs the cutting operation, further improving the automation degree of the equipment.

[0017] (II) The processing equipment and processing method for metal pipe production, when the pressure block approaches the metal pipe, the fitting roller will contact the metal pipe, and finally the two sides of the cutting part of the metal pipe will be clamped and fixed by the fitting roller. While achieving the positioning effect, the friction between the pressure block and the metal pipe is reduced by the rotation characteristics of the fitting roller, thereby avoiding the self-rotation of the metal pipe during the cutting process, greatly improving the stability of the cutting process. At the same time, when the fitting roller contacts and squeezes the metal pipe, the pressure plate will be pressed to slide into the second installation groove under the action of pressure, and the extrusion bag will be squeezed, prompting the extrusion bag to transmit its internal air pressure to the pressure groove. As the internal air pressure of the pressure groove increases, the friction rings on both sides will be pushed closer to each other, that is, the friction between the friction ring and the plug-in ring will be greatly increased, thereby ensuring that the resistance of the resistance ring itself can always support stable work, further improving the working stability of the equipment, and at the same time avoiding the problem of high subsequent maintenance costs caused by the traditional contact friction method causing the friction to drop too quickly, resulting in frequent maintenance.

[0018] (III) The processing equipment and processing method for metal tube production, in the process of the contact between the fitting roller and the outer surface of the metal tube, the tail of the cutting blade will also be in contact with the metal tube first, and then under the action of the extrusion force, the tail of the cutting blade will shrink into the No. 1 mounting groove along with the rotating plate until the cutting blade is completely in contact with the outer surface of the metal tube. The elastic force provided by the elastic plate and the corrugated plate further increases the extrusion force of the cutting blade on the metal tube, thereby ensuring the smoothness of the cutting process. As the cutting proceeds, the tail of the cutting blade begins to gradually move out of the No. 1 mounting groove, so that the tail of the cutting blade automatically expands to match the wall thickness of the metal tube. When the wall thickness is large, the cutting process can still be maintained smoothly. At the same time, compared with the commonly used rotary cutting method, Cutting by cutting gear greatly reduces the pressure on the cutting blade during operation, making the working life of the cutting blade longer, and when the rotating plate moves into the No. 1 mounting groove under the pressure, the elastic plate will begin to shrink, thereby squeezing its internal cavity, and transmitting its internal air pressure to the air gathering groove inside the rotating plate and exporting it through the tail of the cutting blade. The pressure value to which the cutting blade is subjected during operation is not fixed, so the change in pressure value is used to make the air pressure in the air gathering groove in a changing state, and occasionally releasing the air pressure to the outside, which can not only help cool the cutting part, but also blow away the debris in the cutting part, thereby avoiding cutting quality problems caused by the deviation of the cutting blade during operation.

[0032] A processing method for a processing device for producing a metal pipe comprises the following steps: S1, passing the metal pipe through the middle of the mounting ring 31 on the fixing mechanism 3 on one side, and passing through the cutting mechanism 4 until it is output from the middle of the mounting ring 31 on the fixing mechanism 3 on the other side; S2, start the motor 2, drive the connecting shaft 34 to rotate through the motor 2, and drive the No. 1 bearing ring 32 to rotate through the No. 1 driving wheel 33. Under the limiting action of the No. 1 slide groove 36, the positioning clamp 35 begins to shrink inward until it is firmly attached to the outer surface of the metal pipe. At this time, as the motor 2 continues to rotate, the positioning clamp 35 cannot continue to shrink, and the output shaft of the motor 2 begins to rotate relative to the connecting shaft 34. S3, when the motor 2 is started, it will drive the No. 2 driving wheel 44 to rotate, and the No. 2 carrying ring 43 to rotate through the No. 2 driving wheel 44. At this time, under the limiting action of the No. 2 slide groove 411, the pressure block 45 begins to shrink inward until the fitting roller 416 on its inner surface fits the outer surface of the metal tube. At this time, as the motor 2 continues to rotate, the pressure block 45 cannot continue to shrink, and the resistance ring 42 is driven to rotate through the No. 2 slide groove 411, so that the cutting blade 48 accumulated on the outer surface of the metal tube starts to rotate and cut, until the metal tube is finally cut; S4, reverse driving the motor 2, so that the fixing mechanism 3 and the cutting mechanism 4 are separated from the contact with the metal pipe, and the cut metal pipe is taken out, and this cycle forms continuous cutting.

[0033] During operation, the end of the metal pipe to be cut can be inserted into the through hole of the mounting ring 31 on one side, and then pass through the cutting mechanism 4 and out of the through hole of the mounting ring 31 on the other side, and then the motor 2 can be started. When the motor 2 is started, its output shaft will start to rotate, and then the connecting shafts 34 on both sides will start to rotate, and then the No. 1 driving wheel 33 will start to rotate. When the No. 1 driving wheel 33 starts to rotate, it will drive the No. 1 bearing ring 32 to start to rotate, and the positioning clamping block 35 slidably connected in the No. 1 bearing ring 32 is connected to the mounting ring 31 through the No. 1 slide groove 36, that is, when the No. 1 bearing ring 32 starts to rotate, the positioning clamping block 35 will be tightened inward, and finally firmly fit on the outer surface of the metal pipe, thereby automatically completing the fixation of the metal pipe. When the positioning clamp 35 is firmly attached to the outer surface of the metal pipe, the No. 1 driving wheel 33 cannot continue to rotate under the action of the extrusion force. At this time, the output shaft of the motor 2 begins to rotate relative to the connecting shaft 34, thereby driving the No. 2 driving wheel 44 to rotate continuously, forcing the cutting mechanism 4 to continue working, thereby completing the cutting of the metal pipe. By linking the fixing mechanism 3 with the cutting mechanism 4, the two sides of the metal pipe can be automatically clamped and fixed when the metal pipe is cut, which greatly reduces the cutting process, improves the cutting smoothness, and also improves the cutting efficiency. By providing a movable and retractable positioning clamp 35, the device can be matched with metal pipes of different diameters, which also greatly improves the practicality of the device. The No. 2 driving wheel 44 rotates When the pressure block 45 is in contact with the outer surface of the metal tube, the pressure block 45 cannot continue to shrink due to the limiting effect of the second slide groove 411, thereby driving the resistance ring 42 to start rotating, that is, the resistance ring 42 and the second bearing ring 43 are rotated synchronously, and the metal tube is rotationally cut by the cutting blade 48 in the first mounting groove 46 on the pressure block 45, that is, after the metal tube is automatically fixed, it also automatically adapts to the diameter of the metal tube and performs the cutting operation, further improving the automation degree of the equipment, and when the pressure block 45 is close to the metal tube, the fitting roller 416 is in contact with the metal tube, and finally through the fitting The roller 416 clamps and fixes the two sides of the cutting part of the metal tube. While achieving the positioning effect, the friction between the pressure block 45 and the metal tube is reduced by the rotation characteristics of the fitting roller 416, thereby avoiding the self-rotation of the metal tube during the cutting process, which greatly improves the stability of the cutting process. At the same time, when the fitting roller 416 contacts and squeezes the metal tube, the pressure plate 415 is pressed to slide into the second installation groove 413 under the action of pressure, and the squeezing bag 414 is squeezed, so that the squeezing bag 414 transmits its internal air pressure to the pressure groove 418. As the internal air pressure of the pressure groove 418 increases, the friction rings 419 on both sides are pushed closer to each other, which greatly increases the friction between the friction ring 419 and the plug ring 417.This ensures that the resistance of the resistance ring 42 itself can always support stable operation, further improving the working stability of the device, and at the same time avoiding the problem of high subsequent maintenance costs caused by frequent maintenance due to the traditional contact friction method. In the process of the contact between the fitting roller 416 and the outer surface of the metal tube, the tail of the cutting blade 48 will also contact the metal tube first, and then under the action of the extrusion force, the tail of the cutting blade 48 will shrink into the No. 1 mounting groove 46 along with the rotating plate 47 until the cutting blade 48 is completely in contact with the outer surface of the metal tube. The elastic force provided by the elastic plate 49 and the corrugated plate 410 further increases the extrusion pressure of the cutting blade 48 on the metal tube, thereby ensuring a smooth cutting process. As the cutting proceeds, the tail of the cutting blade 48 begins to gradually move in and out of the No. 1 mounting groove 46, so that the tail of the cutting blade 48 automatically expands to match the metal tube. When the wall thickness is large, the smooth cutting process can still be maintained. At the same time, compared with the commonly used cutting by cutting gear, the rotary cutting method greatly reduces the pressure on the cutting blade 48 during the working process, making the working life of the cutting blade 48 longer. When the rotating plate 47 moves into the No. 1 mounting groove 46 under the pressure, the elastic plate 49 will begin to shrink, thereby squeezing the internal cavity and transmitting its internal air pressure to the air gathering groove 412 inside the rotating plate 47 and exporting it through the tail of the cutting blade 48. The pressure value received by the cutting blade 48 during the working process is not fixed, so the change of the pressure value makes the air pressure in the air gathering groove 412 in a variable state, and sometimes releases the air pressure to the outside, which can not only help cool the cutting part, but also blow away the debris in the cutting part, avoiding the cutting quality problem caused by the deviation of the cutting blade 48 during the working process.

[0034] The above are only 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 in the protection scope of the present invention.
