Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coil processing, in particular to a coil processing tool. BACKGROUND

[0002] In the field of coil processing, cold drawing technology plays a crucial role. Its core principle is to apply precise tension to the pipe material with the help of special equipment, so that the pipe material undergoes controllable plastic deformation under the constraint of specially designed molds. This process is like a skilled sculptor who can achieve precise shaping of key size parameters such as coil outer diameter, inner diameter and wall thickness through careful sculpting of the pipe material. The dimensional accuracy can reach ±0.05mm or even higher, which is a model of modern industrial precision manufacturing.

[0003] High-precision coils are like precision gears in equipment operation, and can seamlessly integrate with other components during installation and use. This precise fit greatly reduces the leakage problem caused by dimensional deviation, like adding a solid defense line to the sealing system of the equipment, effectively preventing the leakage of the medium and ensuring the stability of the internal environment of the equipment. At the same time, it can also significantly reduce the vibration during equipment operation, like installing an efficient shock absorber for a high-speed running machine, making the equipment run more smoothly and stably, thereby greatly improving the running stability and reliability of the equipment, prolonging the service life of the equipment and reducing maintenance costs.

[0004] However, the current cold drawing process still faces many problems to be solved in practical application, which makes it difficult to achieve the ideal state of cold drawing effect.

[0005] In the existing cold drawing process, the friction between the mold and the pipe surface is a key factor affecting the surface quality. Since the mold is fixed, the pipe material has a large and uneven friction with the inner wall of the mold when passing through the mold. This friction is like sandpaper repeatedly polishing the surface of the pipe, which not only causes scratches, scratches and other defects on the surface of the pipe, but also increases the surface roughness. Rough surfaces are prone to adsorbing impurities and pollutants in the medium, forming a scale layer. The scale layer not only reduces the heat exchange efficiency of the coil, like wearing a thick cotton coat on the heat exchanger, hindering the transfer of heat; also accelerates the corrosion of the pipe material, shortens the service life of the coil. In some chemical and refrigeration equipment with high requirements for heat exchange efficiency, the coil with poor surface quality will seriously affect the performance and production efficiency of the equipment.

[0006] The plastic deformation in the cold drawing process can cause significant changes in the internal structure of the pipe material, such as grain refinement and dislocation density increase, which have an important influence on the mechanical properties of the coil. However, due to the uneven stress distribution in the existing cold drawing process, the deformation degree of each part of the pipe material is different, which further causes the internal structure and performance to be uneven. For example, in some areas, due to the excessive deformation, grain refinement may occur, and even cracks and other defects may be generated; in other areas, the deformation is insufficient, the grain refinement effect is not obvious, and the mechanical properties cannot be effectively improved. This unevenness of the internal structure and performance makes the coil have different load-bearing capacities at different parts, and during the operation of the equipment, local stress concentration is easy to occur, which leads to premature failure of the coil and increases the safety hazards of the equipment.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1、The present application, after the pipe clamping is completed, through the specific electromagnetic valve state setting, makes the lubricating oil spray to the processing part through the liquid outlet pipe, lubricates the pipe and the extrusion sleeve being processed. This lubrication method greatly reduces the friction between the pipe and the extrusion sleeve, avoids the surface damage caused by friction as in the traditional process, thereby effectively reducing the generation of surface quality defects.

[0021] 2、There is a cold drawing process due to uneven stress distribution, resulting in different deformation degrees of each part of the pipe, and internal organization performance is not uniform, such as excessive grain refinement in some areas even cracks, and insufficient deformation and unobvious grain refinement effect in other areas.

[0023] 4、The present application realizes the reciprocating motion of the second piston cylinder by driving the circular plate, connecting rod and other components through the driving structure, and then accurately controls the flow of lubricating oil, drives the first moving piston to drive the extrusion rod and the pressing plate to clamp and release the pipe. When the pipe moves to a certain position and the pressure sensor detects the set pressure value, the controller can timely control the electromagnetic valve to act, so as to realize accurate resetting and re-clamping of the pressing plate. This precise control method ensures stable clamping of the pipe during processing, avoids pipe shaking or deformation caused by unstable clamping, and ensures the stability of the processing quality.

[0024] 5、During pipe processing, through the cooperation of the pressure sensor and the controller, automatic loosening and re-clamping of the pressing plate is realized, so that the pipe can continuously and stably enter the extrusion sleeve for processing. This continuous processing method improves the production efficiency, and further ensures the stability and consistency of the coil processing quality due to the accuracy of the pipe position ensured by each clamping.

[0025] In summary, the present application realizes high-quality cold drawing processing of the pipe, effectively solves the problems existing in the existing cold drawing process, improves the uniformity of the surface quality and internal organization performance of the coil, and utilizes the structure capable of intermittently clamping the pipe to ensure that the pipe does not rotate, thereby ensuring the processing quality.

[0045] Wherein, the driving shaft 16 is fixed with a circular plate 18, the mounting frame 5 is installed with a second piston cylinder 19, the circular plate 18 is eccentrically hinged with a connecting rod 21, the second piston cylinder 19 is slidably connected with a second moving piston 20, the second moving piston 20 is hingedly connected with the connecting rod 21, the second piston cylinder 19 is connected with a liquid inlet pipe 25 and a liquid outlet pipe 24, the liquid inlet pipe 25 and the liquid outlet pipe 24 are both arranged through the mounting frame 5, the liquid outlet pipe 24 is arranged towards the processing part 22, and a liquid outlet check valve 27 is installed on the liquid outlet pipe 24, the liquid outlet check valve 27 only allows lubricating oil to flow through the second piston cylinder 19 into the liquid outlet pipe 24; a liquid inlet check valve 26 is installed on the liquid inlet pipe 25, the liquid inlet check valve 26 only allows lubricating oil to enter the second piston cylinder 19 through the liquid inlet pipe 25.

[0046] The liquid inlet pipe 25 and the liquid outlet pipe 24 are respectively connected with a first liquid sending pipe 28 and a second liquid sending pipe 29, the first liquid sending pipe 28 and the second liquid sending pipe 29 are connected with a conveying pipe 23, one of the first piston cylinders 36 is installed with a connecting cylinder 38, the conveying pipe 23 is connected with the connecting cylinder 38, the first liquid sending pipe 28 and the liquid inlet pipe 25 are both installed with a first electromagnetic valve 30, the liquid outlet pipe 24 and the second liquid sending pipe 29 are both installed with a second electromagnetic valve 31, and the pressure sensor 33 is connected with the first electromagnetic valve 30 and the second electromagnetic valve 31 through a controller.

[0047] In addition, the rack 1 is provided with a movable movable plate 2, the movable plate 2 is provided with a support rod 3 coaxial with the guide pipe 8, and the support rod 3 is fixed with a resisting disc 4 abutting against the pipe; the movable plate 2 can be moved by hydraulic drive or chain drive, and slides on the rack 1 through a guide rail.

[0048] The principle of the pipe processing of the present application is as follows:

[0049] The end of the pipe to be processed is placed on the support rod 3 of the movable plate 2 and is coaxially supported by the support rod 3, so that the pipe is abutted against the resisting disc 4, and the position of the pipe is stable in the initial stage of processing. Then the movable plate 2 drives the support rod 3 to move so that the pipe is located in the sleeve 39, and then the pipe is clamped.

[0050] Specifically:

[0051] The driving structure 14 is started, the driving structure 14 composed of a reduction box and a reduction motor starts to operate, and the output end drives the driving shaft 16 to rotate. The driving shaft 16 penetrates through the support block 17 and is rotatably connected with the support block 17, so as to ensure the stability of the rotation of the driving shaft 16.

[0052] When the driving shaft 16 rotates, the circular plate 18 fixed on the driving shaft 16 also rotates. The circular plate 18 is eccentrically connected with a connecting rod 21, and the other end of the connecting rod 21 is connected with the second piston cylinder 19. The rotation of the circular plate 18 drives the second piston cylinder 19 to move reciprocatingly in the second piston cylinder 19 through the connecting rod 21.

[0053] At this time, the first electromagnetic valve 30 on the liquid inlet pipe 25 is in the open state, the first electromagnetic valve 30 on the first liquid feeding pipe 28 is in the closed state, the second electromagnetic valve 31 on the liquid outlet pipe 24 is in the closed state, and the second electromagnetic valve 31 on the second liquid feeding pipe 29 is in the open state.

[0054] When the second piston cylinder 19 moves away from the liquid inlet pipe 25, a negative pressure is formed in the second piston cylinder 19, the liquid inlet check valve 26 is opened, and the lubricating oil enters the second piston cylinder 19 through the liquid inlet pipe 25; when the second piston cylinder 19 moves towards the liquid outlet pipe 24, the pressure in the second piston cylinder 19 increases, the liquid outlet check valve 27 is opened, and the lubricating oil flows into the delivery pipe 23 through the liquid outlet pipe 24 and the second liquid feeding pipe 29, then flows into the connecting cylinder 38 through the delivery pipe 23, and then flows into the first piston cylinder 36 through the connecting cylinder 38. Under the action of the connecting pipe 37, the lubricating oil flows into the three first piston cylinders 36, the hydraulic oil in the first piston cylinder 36 increases, thereby driving the first moving piston 41 to move, and the first moving piston 41 moves the extrusion rod 43 and the pressing plate 40, and finally the three pressing plates 40 abut against the pipeline, thereby clamping the pipeline, so that the pipeline is not rotated by the extrusion sleeve 11.

[0055] After the pipeline is clamped, the first electromagnetic valve 30 on the liquid inlet pipe 25 is in the open state, the first electromagnetic valve 30 on the first liquid feeding pipe 28 is in the closed state, the second electromagnetic valve 31 on the liquid outlet pipe 24 is in the open state, and the second electromagnetic valve 31 on the second liquid feeding pipe 29 is in the closed state.

[0056] As described above, the lubricating oil is sprayed to the machining part 22 through the liquid outlet pipe 24, so as to lubricate the pipeline and the extrusion sleeve 11 being machined, reduce friction, reduce the generation of surface quality defects, and improve the machining quality.

[0057] At this time, the moving plate 6 is in the initial position, the sliding block 35 is also in the corresponding position in the guide pipe 8, the second spring 34 is in the natural state, and the pressure sensor 33 detects the initial pressure value.

[0058] The first gear 15 on the drive shaft 16 rotates, and since the first gear 15 is engaged with the second gear 12 fixed on the support plate 10, the rotation of the first gear 15 drives the second gear 12 to rotate, and in turn drives the extrusion sleeve 11 fixedly connected with the second gear 12 to rotate on the support plate 10. The extrusion sleeve 11 is provided with a processing portion 22, including a tapered groove for reducing the wall thickness of the pipe and a circular groove for rounding the pipe with reduced wall thickness, and the circular groove is in communication with the tapered groove, preparing for subsequent processing of the pipe.

[0059] While the extrusion sleeve 11 rotates, the pipe is moved horizontally by an external traction device, so that the pipe gradually enters the rotating extrusion sleeve 11. The pipe first enters the tapered groove, and under the action of the tapered groove, the wall thickness of the pipe is gradually reduced, realizing the wall reduction processing. With the continuous movement of the pipe, the pipe enters the circular groove, and the circular groove rounds the pipe after wall reduction, so that the outer diameter and roundness of the pipe meet the requirements, thus completing the wall reduction processing of the elbow pipe.

[0060] With the movement of the pipe, the moving plate 6 drives the connecting rod 9 and the sliding block 35 to slide in the guide pipe 8, and the second spring 34 is compressed. The pressure sensor 33 detects the change of pressure. When the pipe moves to a certain position and the pressure detected by the pressure sensor 33 reaches a set value, the pressure sensor 33 transmits a signal to the controller, and the controller controls the first electromagnetic valve 30 and the second electromagnetic valve 31 to act.

[0061] Specifically, the first electromagnetic valve 30 on the liquid inlet pipe 25 is in a closed state, the first electromagnetic valve 30 on the first liquid feeding pipe 28 is in an open state, the second electromagnetic valve 31 on the liquid outlet pipe 24 is in an open state, and the second electromagnetic valve 31 on the second liquid feeding pipe 29 is in a closed state.

[0062] In this way, the lubricating oil in the plurality of first piston cylinders 36 can be sucked away, the pressure plate 40 can be reset and moved, and the extrusion rod 43 and the pressure plate 40 can be loosened to clamp the pipe. At the same time, under the elastic force of the second spring 34, the sliding block 35 drives the connecting rod 9 and the moving plate 6 to move to the original horizontal position. Subsequently, the controller controls the first electromagnetic valve 30 and the second electromagnetic valve 31 to return to the initial state, and the first moving piston 41 is reset under the action of the first spring 42. The pressure plate 40 clamps the pipe again, and subsequent processing is continued. Since the clamped part of the pipe is close to the extrusion sleeve 11, the pipe can be effectively limited to avoid deformation due to torsion, and the quality of the coil pipe processing is ensured.

[0063] Through the cooperative work of the above components, the coil pipe processing tool realizes high-quality cold drawing processing of the pipe, effectively solves the problems existing in the existing cold drawing process, and improves the surface quality and uniformity of the internal organization performance of the coil pipe.

[0064] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
