Description

Technical Field

[0001] The present invention belongs to the technical field of titanium alloy pipe fitting processing, and in particular relates to a hot shrink forming device for titanium alloy pipe fittings and a forming method thereof. Background Art

[0002] The hot shrink forming device for titanium alloy pipe fittings is a special device for hot shrink forming titanium alloy pipe fittings. Titanium alloy pipe fittings are widely used in the industrial field. Due to their good corrosion resistance and high strength characteristics, the device applies heat to the titanium alloy pipe fittings to heat them partially or integrally to a certain temperature, and then uses a special mold to form them. For example, a hot shrink forming device for titanium alloy pipe fittings proposed in the patent publication number CN222058505U.

[0003] When the existing hot shrink forming device processes titanium alloy pipe fittings, it is necessary to heat the pipe fittings first, and then insert the heated pipe fittings into the mold to complete the hot shrink. However, there may be oil stains, lubricants, oxide scales or metal dust generated during processing such as cutting and grinding remaining on the surface of the titanium alloy pipe. During hot shrink forming, these substances will adhere or carbonize with the surface of the mold in a high-temperature environment, forming attachments. At the same time, if the lubricant inside the mold decomposes or volatilizes incompletely at high temperature, substances such as residual coke and carbon deposits may be generated and adhere to the inner wall of the mold to form foreign objects. When there are foreign objects on the inner wall of the mold, during subsequent hot shrink processing of titanium alloy pipe fittings, the foreign objects will scratch the surface of the pipe fittings, thereby affecting the hot shrink quality of the titanium alloy pipe fittings.

[0004] Therefore, a hot shrink forming device for titanium alloy pipe fittings and a forming method thereof are proposed to solve the above problems. Summary of the Invention

[0024] The operating principle of the present invention is described as follows: Insert multiple titanium alloy pipe fittings into multiple clamping cylinders 38 respectively, and then send an electrical signal to the controller 2 through an external switch. After receiving the electrical signal, the controller 2 will control multiple clamping hydraulic cylinders 39 to work simultaneously. The clamping hydraulic cylinders 39 will drive the clamping plates 40 to move within the clamping cylinders 38, and use the clamping plates 40 to clamp the titanium alloy pipe fittings. After all the titanium alloy pipe fittings are fixed, the installation positions of the titanium alloy pipe fittings are set. One of the titanium alloy pipe fittings will be located directly below the heating electric coil 8. After the controller 2 finishes controlling the clamping hydraulic cylinders 39 to work, it will control the first hydraulic cylinder 7 on the right to work. The first hydraulic cylinder 7 on the right will drive the heating electric coil 8 to move downward. At the same time, the controller 2 will also control the heating electric coil 8 to be powered on and work, and use the heating electric coil 8 to heat-treat the titanium alloy pipe fitting. When the heating electric coil 8 works for the set time (10 seconds), the controller 2 will control the first hydraulic cylinder 7 on the right to drive the heating electric coil 8 to move upward to the set position and control the heating electric coil 8 to stop working. Then, the controller 2 controls the rotation motor 4 to work. The rotation motor 4 will drive the rotating plate 5 to rotate to the set angle, so that the rotating plate 5 drives the heated titanium alloy pipe fitting to be located directly below the heat shrinkage mold 9, and another titanium alloy pipe fitting is located directly below the heating electric coil 8. Then, the controller 2 repeats the above steps to heat-treat the titanium alloy pipe fitting with the heating electric coil 8. At the same time, the controller 2 will also control the first hydraulic cylinder 7 on the left to work. The first hydraulic cylinder 7 on the left will drive the heat shrinkage mold 9 to move downward. At the same time, the controller 2 will also control the corresponding control motor 41 to work, and use the control motor 41 to drive the clamping assembly 44 and the titanium alloy pipe fitting above to rotate, so that the heat shrinkage mold 9 can be used to perform heat shrinkage treatment on the titanium alloy pipe fitting. When the titanium alloy pipe fitting is heat-shrunk (the heat shrinkage treatment time of the titanium alloy pipe fitting is less than the time used in the heating process), the controller 2 will control the left hydraulic cylinder to drive the heat shrinkage mold 9 to move upward to the initial position, and control the rotation motor 4 to continue working, move another heated titanium alloy pipe fitting below the heat shrinkage mold 9, and move the heat-shrunk titanium alloy pipe fitting beside the vision sensor 43. During the heat shrinkage treatment process of another titanium alloy pipe fitting, the controller 2 will also control the corresponding control motor 41 to work, use the control motor 41 to drive the heat-shrunk titanium alloy pipe fitting to rotate, and the controller 2 will also use the vision sensor 43 to detect the surface of the titanium alloy pipe fitting; When the controller 2 detects a scratch on the surface of the titanium alloy pipe fitting using the vision sensor 43, it indicates that there is an attachment on the inner wall of the heat shrinkage mold 9. The controller 2 will control the heat shrinkage operation to pause. Then, the controller 2 controls the rotary motor 4 to drive the rotating plate 5 to rotate a small angle, so that the titanium alloy pipe fitting below the heat shrinkage mold 9 is moved away. Then, the controller 2 controls the horizontal electric push rod 10 to work. The horizontal electric push rod 10 will drive the moving plate 11 to move forward, and drive the lifting cylinder 122 and the detection cylinder 13 to move to directly below the heat shrinkage mold 9 through the moving plate 11. Then, the controller 2 controls the lifting electric push rod 121 to work. The lifting electric push rod 121 will drive the lifting cylinder 122 and the detection cylinder 13 to move upward together. The detection cylinder 13 will drive the detection box 15 and the arc-shaped detection piece 45 to move into the heat shrinkage mold 9 together. The arc-shaped detection piece 45 and the inner wall of the heat shrinkage mold 9 cooperate with each other. When the lifting electric push rod 121 drives the arc-shaped detection piece 45 to move upward to the set position and the arc-shaped detection piece 45 does not contact the attachment, the controller 2 will control the driving motor 14 to work. The driving motor 14 drives the detection cylinder 13 to rotate a certain angle through the gear and rack transmission assembly, and drives the detection box 15 and the arc-shaped detection piece 45 to rotate a certain angle by using the detection cylinder 13. Then, the controller 2 controls the lifting electric push rod 121 to drive the arc-shaped detection piece 45 to move downward to detect other areas of the inner wall of the heat shrinkage mold 9. When the arc-shaped detection piece 45 contacts the attachment during the downward movement, the arc-shaped detection piece 45 will drive the square rod 17 to rotate around the connecting shaft 16, and the square rod 17 will drive the conductive rod 18 to move downward together. When the size of the attachment is large, the square rod 17 will drive the conductive rod 18 to rotate a large angle, and the conductive rod 18 will contact the position near the upper end or the lower end of the arc-shaped resistance plate 19. The conductive rod 18 is electrically connected to the external power supply, and the two ends of the arc-shaped resistance plates 19 away from each other (the upper end of the upper arc-shaped resistance plate 19 or the lower end of the lower arc-shaped resistance plate 19) are electrically connected to the controller 2, so that the resistance connected to the controller 2 becomes smaller. When the external voltage remains unchanged, the current signal transmitted to the circuit of the controller 2 will increase. When the controller 2 detects a large current signal (exceeding 0.5 mA), it indicates that the size of the attachment is large. The controller 2 will control the driving motor 14 to drive the detection cylinder 13 to immediately rotate 180 degrees, so that the cleaning component 20 moves to this area. Then, the controller 2 controls the cleaning electric push rod 201 to drive the polishing frame 202 and the spherical polishing seat 21 to move to the set position. Then, the controller 2 controls the lifting electric push rod 121 to drive the cleaning component 20 to move upward to polish and clean the large attachment using the spherical polishing seat 21; When the controller 2 detects a smaller current signal (less than 0.5 mA), indicating that the size of the attached object is small, the controller 2 will control the lifting electric push rod 121 to drive the detection cylinder 13 upward to the highest position, and control the air pump 29 to work and control the first control valve 33 to open. The air pump 29 will transport external gas through the air delivery pipe 30 into the installation cylinder 231, increasing the air pressure inside the piston plate 25. The piston plate 25 will drive the scraping frame 26 to move towards the inner wall of the heat shrinkage mold 9 through the adjusting rod 24, so that the grinding strips 28 on the surfaces of the scraping frame 26 and the strip plate 27 come into contact with the inner wall of the heat shrinkage mold 9. And when the controller 2 detects through the set air pressure sensor 31 that the air pressure inside the installation cylinder 231 reaches the set threshold value (0.01 standard atmospheric pressure), the controller 2 will control the air pump 29 to stop working and control the first control valve 33 to close. Then the controller 2 controls the lifting electric push rod 121 to drive the lifting cylinder 122, the detection cylinder 13, the expanded scraping frame 26 and the strip plate 27 to move downward together (the scraping frame 26 and the strip plate 27 form a circle), and uses the grinding strips 28 on the surfaces of the scraping frame 26 and the strip plate 27 to clean the remaining lubricant and smaller attached objects on the inner wall of the heat shrinkage mold 9. When the cleaning work is over, the controller 2 will control the first control valve 33 and the second control valve 34 to open simultaneously, so that the gas inside the installation cylinder 231 and the adjusting cylinder 232 is discharged together through the air delivery pipe 30, the elbow pipe 32 and the multiple nozzles 35; Subsequently, the controller 2 can also control the air pump 29 to work and control the regulating valve 37 and the second control valve 34 to open. The external lubricant conveying mechanism is used to convey the lubricant through the infusion pipe 36 to the air outlet end of the air pump 29. The air pump 29 will use the gas to convey the lubricant to the nozzle 35 through the air delivery pipe 30 and the elbow pipe 32, and use the nozzle 35 to spray out the lubricant. At the same time, the controller 2 will also control the lifting electric push rod 121 and the driving motor 14 to work, so that the detection cylinder 13 drives the nozzle 35 to move up and down and rotate inside the heat shrinkage mold 9, and evenly spray the lubricant onto the inner wall of the heat shrinkage mold 9 to reduce the friction between the heat shrinkage mold 9 and the titanium alloy pipe fitting.
