Description

Technical Field

[0001] This invention relates to the field of stainless steel seamless tube technology, specifically to a production process and equipment for corrosion-resistant duplex stainless steel seamless tubes used in new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Since duplex stainless steel seamless tubes are required in the production and manufacturing process of new energy vehicles, corresponding equipment is needed to produce duplex stainless steel seamless tubes into the specifications required for new energy vehicles.

[0004] Duplex stainless steel pipes have good weldability. Compared with ferritic stainless steel and austenitic stainless steel, they are not like the weld heat-affected zone of ferritic stainless steel, where the toughness and plasticity are greatly reduced due to severe grain coarsening, nor are they as sensitive to weld hot cracking as austenitic stainless steel.

[0005] Due to its unique advantages, duplex stainless steel is widely used in industrial fields such as petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, and papermaking machinery.

[0006] However, existing equipment for producing corrosion-resistant duplex stainless steel seamless tubes, such as duplex stainless steel seamless tube cutting equipment, has a limited number of duplex stainless steel seamless tubes that can be cut at one time, which affects the processing efficiency. At the same time, the processing function is relatively simple and cannot be matched with various processing heads to perform different processing on duplex stainless steel seamless tubes, thus having significant limitations.

[0007] Therefore, it is essential to invent a production process and equipment for corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles. Summary of the Invention

[0008] The purpose of this invention is to provide a production process and equipment for corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles, in order to solve the problems of existing duplex stainless steel seamless tube cutting equipment. In the process of cutting duplex stainless steel seamless tubes, the number of tubes cut at one time is limited, which affects the processing efficiency of duplex stainless steel seamless tubes. At the same time, the processing function is relatively simple and cannot be matched with various processing heads to perform different processing on duplex stainless steel seamless tubes, thus having great limitations.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A production process for corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles, comprising the following steps:

[0010] When cutting duplex stainless steel seamless tubes, select a cutting blade that is compatible with the processing head connector.

[0012] The first step is to select duplex stainless steel seamless tubes for new energy vehicles and place them sequentially on a semi-circular plate.

[0013] The second step is to retract the bidirectional electric push rod, which drives the two tube racks to move the duplex stainless steel seamless tubes between the rear H-frame plate and the front H-frame plate.

[0014] The third step involves using the linear guide to drive the electric gripper on the H-frame plate to approach the duplex stainless steel seamless tube on the tube rack. Once the gripper extends into the interior of one end of the duplex stainless steel seamless tube, the movement stops, allowing the gripper to open and abut against the inner wall of the duplex stainless steel seamless tube, thus completing the fixation of the duplex stainless steel seamless tube.

[0015] Fourth step, continue to drive the linear guide rail to move the H-frame plate to one side of the front H-frame plate, so that one end of the duplex stainless steel seamless tube passes into the corresponding positioning hole two, and then stop moving;

[0016] Fifth step: The hydraulic cylinder retracts, the semi-circular plate separates from the corresponding duplex stainless steel seamless tube, and the bidirectional electric push rod unfolds, so that the two tube racks move out from between the rear H-frame plate and the front H-frame plate, and the first step is repeated.

[0017] Step 6: Continue to drive the linear guide rail one to move the H-frame plate to one side of the front H-frame plate, so that one end of the duplex stainless steel seamless tube protrudes from the corresponding positioning hole two by the required length, and then stop moving.

[0018] Step 7: Start the drive motor to drive all the electric grippers and rotate the corresponding duplex stainless steel seamless tubes.

[0019] Step 8: Drive the processing head connecting seat with the linear guide rail 2 to move the cutter to one side of the front H-frame plate, so that the cutter plate 1 contacts the duplex stainless steel seamless tube on one side of the front H-frame plate. Under the rotation of the duplex stainless steel seamless tube, the duplex stainless steel seamless tube is cut. After cutting, drive the processing head connecting seat with the linear guide rail 2 to move the cutter to the other side of the front H-frame plate, so that the cutter plate 2 contacts the duplex stainless steel seamless tube on the other side of the front H-frame plate. Under the rotation of the duplex stainless steel seamless tube, the duplex stainless steel seamless tube is cut.

[0020] In the ninth step, the cut duplex stainless steel seamless tubes will fall onto the guide plate, which will then guide them to one side.

[0053] This invention provides a manufacturing process for corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles, comprising the following steps:

[0054] When it is necessary to cut the duplex stainless steel seamless tube 10, select a cutter 8 that is compatible with the processing head connector 7;

[0055] In the initial state, the bidirectional electric push rod 5 and the hydraulic cylinder 65 are in the fully extended state, the two tube racks 6 are on both sides of the rear H-frame plate 3 and the front H-frame plate 4 respectively, the rear H-frame plate 3 is at the initial end of the linear guide rail 2, and the cutter 8 is in the middle position of the front H-frame plate 4.

[0056] The first step is to select duplex stainless steel seamless tubes 10 for new energy vehicles and place them on the semi-circular plate 63 in sequence.

[0057] The second step is to retract the bidirectional electric push rod 5, which drives the two tube racks 6 to move the duplex stainless steel seamless tube 10 between the rear H-frame plate 3 and the front H-frame plate 4.

[0058] The third step is to drive the electric gripper 9 on the H-frame plate 3 to approach the duplex stainless steel seamless tube 10 on the tube rack 6 via the linear guide rail 2. After the gripper 9 of the electric gripper 9 extends into the interior of one end of the duplex stainless steel seamless tube 10, stop moving and let the gripper 9 of the electric gripper 9 open up and abut against the inner wall of the duplex stainless steel seamless tube 10 to complete the fixation of the duplex stainless steel seamless tube 10.

[0059] Fourth step, continue to drive the linear guide rail 2 to move the rear H-frame plate 3 to one side of the front H-frame plate 4, so that one end of the duplex stainless steel seamless tube 10 passes into the corresponding positioning hole 41, and then stop moving.

[0060] Fifth step, the hydraulic cylinder 65 retracts, the semi-circular plate 63 separates from the corresponding duplex stainless steel seamless tube 10, and the bidirectional electric push rod 5 unfolds, so that the two tube racks 6 move out from between the rear H-frame plate 3 and the front H-frame plate 4, and the first step is repeated.

[0061] Step 6: Continue to drive the linear guide rail 2 to move the rear H-frame plate 3 to one side of the front H-frame plate 4, so that one end of the duplex stainless steel seamless tube 10 protrudes from the corresponding positioning hole 41 by the required length, and then stop moving.

[0062] Step 7: Start the drive motor 33 to drive all the electric grippers 9 to rotate the corresponding duplex stainless steel seamless tubes 10.

[0063] Step 8: Drive the processing head connecting seat 7 via the linear guide to move the cutter 8 to one side of the front H-frame plate 4, so that the first cutter plate 81 contacts the duplex stainless steel seamless tube 10 on one side of the front H-frame plate 4.

[0064] In the ninth step, the cut duplex stainless steel seamless tube 10 will fall onto the guide plate 13, and the guide plate 13 will guide the cut duplex stainless steel seamless tube 10 to one side.

[0065] Step 10: Repeat steps 6 to 9 until the entire duplex stainless steel seamless tube 10 is cut; then repeat this cycle.

[0066] This invention also relates to a production equipment for corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles, comprising a base 1, a linear guide rail 2, a rear H-frame plate 3, a front H-frame plate 4, and a duplex stainless steel seamless tube 10. The linear guide rail 2 has the H-frame plate 3 and the front H-frame plate 4 fixedly mounted on it. The linear guide rail 2 drives the H-frame plate 3 to push the duplex stainless steel seamless tube 10 through the front H-frame plate 4.

The rear H-frame plate 3 is slidably connected to the base 1, ensuring the stability of each electric gripper 9. A bidirectional electric push rod 5 is fixedly mounted on the base 1. By setting up the bidirectional electric push rod 5, the tube rack 6 can be driven to carry the duplex stainless steel seamless tube 10 close to the H-frame plate 3 and the front H-frame plate 4 and away from the H-frame plate 3 and the front H-frame plate 4, so as to automatically feed the tubes. The two output ends of the bidirectional electric push rod 5 are each fixedly installed with a tube rack 6. The tube rack 6 facilitates the placement of the corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles and ensures the stability of the corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles. The tube rack 6 is slidably connected to the base 1. The two tube racks 6 are located on both sides of the rear H-frame plate 3 and the front H-frame plate 4, and are set in a mirror position with the rear H-frame plate 3 and the front H-frame plate 4 as the center. The duplex stainless steel seamless tubes 10 are evenly distributed on the tube rack 6.

[0067] It should be noted that when the bidirectional electric push rod 5 is fully retracted, the two pipe racks 6 are located between the H-frame plate 3 and the front H-frame plate 4, and the maximum distance between the H-frame plate 3 and the front H-frame plate 4 is greater than the length of the pipe rack 6.

[0068] In this embodiment, several electric grippers 9 for fixing duplex stainless steel seamless tubes 10 are evenly and rotatably installed on the two vertical plates on the side of the rear H-frame plate 3 facing the front H-frame plate 4. By setting the electric grippers 9, the duplex stainless steel seamless tubes 10 can be fixed to ensure the stability of the duplex stainless steel seamless tubes 10 during the production and processing process. The grippers 9 extend into the interior of one end of the duplex stainless steel seamless tubes 10 and abut against the inner wall of the duplex stainless steel seamless tubes 10.

[0069] The electric gripper 9 uses existing technology, such as the existing dual-jaw electric gripper, so it will not be described in detail here.

[0070] In this embodiment, several positioning holes 41 are evenly distributed and penetrated on each of the two vertical plates of the front H-frame plate 4. The positioning holes 41 ensure the stability of the duplex stainless steel seamless tube 10 between the front H-frame plate 4 and the rear H-frame plate 3. Each positioning hole 41 corresponds to an electric gripper 9. An electric heating wire is fixedly installed in the positioning hole 41, and the controller of the electric heating wire is fixedly installed in the electrical control box 15. The electric heating wire can heat the duplex stainless steel seamless tube 10 passing through the positioning hole 41. A linear guide rail is fixedly installed on the horizontal plate on the opposite side of the front H-frame plate 4 and the rear H-frame plate 3. The linear guide rail 2 enables the machining head connector 7 to carry the cutter 8 or other machining heads to reciprocate between the two vertical plates of the front H-frame plate 4. The machining head connector 7 is fixedly installed on the linear guide rail 2. The machining head connector 7 facilitates the replacement of different machining tools for the duplex stainless steel seamless tube 10. The cutter 8 is detachably fixedly installed on the machining head connector 7. The cutter 8 can cut the duplex stainless steel seamless tube 10 that passes through the positioning hole 41 on the front H-frame plate 4. One end of the duplex stainless steel seamless tube 10 passes through the corresponding positioning hole 41.

[0071] In this embodiment, the rear H-frame plate 3 has an internal mounting cavity 31 that matches its shape. The mounting cavity 31 provides operating space for the gear and gear 91, ensuring stability between them. Several positioning holes 32 are provided on the two vertical plates of the rear H-frame plate 3. These positioning holes 32 ensure smooth and stable rotation of the electric grippers 9. The positioning holes 32 communicate with the mounting cavity 31. A drive motor 33 is fixedly mounted on the horizontal plate of the rear H-frame plate 3. Through the interaction between the drive motor 33 and the gear and gear 91, all electric grippers 9 can be driven to rotate 360 ​​degrees. The output end of the drive motor 33 rotates into the mounting cavity 31, and a gear is fixedly mounted on its output end. The gear is rotatably mounted in the mounting cavity 31 and meshes with the corresponding electric gripper 9. The electric gripper 9 is rotatably mounted in the corresponding positioning hole 32.

[0072] In this embodiment, a positioning post 92 is fixedly installed at the tail of the electric gripper 9. The positioning post 92 ensures smoothness and stability during rotation between the electric gripper 9 and the positioning hole 32. A conductive slip ring 93 is sleeved on the outside of the positioning post 92. The conductive slip ring 93 prevents the wiring harness of the electric gripper 9 from becoming entangled during rotation. The positioning post 92 is fixedly connected to the inner ring of the conductive slip ring 93. A gear 91 is fixedly installed at the other end of the positioning post 92. The two gears 91 are evenly distributed and rotatably installed on both sides inside the mounting cavity 31; the gears 91 on every two adjacent electric grippers 9 are meshed and connected, and one of the gears 91 on each side inside the mounting cavity 31 is meshed with a gear; the electric grippers 9 are electrically connected to the wires on the inner ring of the conductive slip ring 93, and the outer ring of the conductive slip ring 93 is fixedly installed on the rear H-frame plate 3 and is coaxial with the corresponding positioning hole 32; the positioning pin 92 is rotatably installed in the corresponding positioning hole 32 and is coaxial with the corresponding positioning hole 32.

[0073] In this embodiment, the base 1 has a positioning cavity 11 and two limiting grooves 12. A guide plate 13 is detachably and fixedly installed at one end of the base 1 near the front H-frame plate 4. The guide plate 13 can guide the cut duplex stainless steel seamless tubes 10 to one side. An electrical control box 15 is fixedly installed on the base 1.

The bidirectional electric push rod 5 is fixedly installed in the positioning cavity 11. The positioning cavity 11 facilitates the installation of the bidirectional electric push rod 5 and ensures the stability of the bidirectional electric push rod 5 during operation. The tube frame 6 is slidably connected to the corresponding limiting groove 12. The limiting groove 12 can ensure the smoothness and stability of the tube frame 6 during movement. The two limiting grooves 12 are set in a mirror position with the positioning cavity 11 as the center.

[0074] The controller uses existing technology, such as PLC, so we will not go into too much detail about it here.

[0075] In this embodiment, the upper surface of the guide plate 13 is inclined, and a limiting plate 14 is fixedly installed at the high end of the inclined surface of the guide plate 13. By setting the limiting plate 14, the cut duplex stainless steel seamless tube 10 can be limited to prevent the cut duplex stainless steel seamless tube 10 from falling in inconsistent positions.

A motor is fixedly installed inside the housing 22, and the output end of the motor rotatably passes through the housing 22 and the support platform 21. 1. One end of the lead screw 26 is fixedly connected. Through the arrangement between the motor, the lead screw 26 and the slide 27, the motor can drive the lead screw 2 to rotate, so that the slide 27 moves on the lead screw 2, thereby carrying the rear H-frame plate 3 closer to or away from the front H-frame plate 4; A through hole 24 is provided through the bottom of the support platform 21. Through the through hole 24, it can be installed together with the bidirectional electric push rod 5.

[0083] In this implementation:

[0084] When it is necessary to cut the duplex stainless steel seamless tube 10 for new energy vehicles, first select the cutter 8 that is compatible with the processing head connecting seat 7, then reverse the motor to move the rear H-frame plate 3 away from the front H-frame plate 4 until the distance between the rear H-frame plate 3 and the front H-frame plate 4 is greater than the length of the tube frame 6. At this time, select the duplex stainless steel seamless tube 10 for new energy vehicles and place the duplex stainless steel seamless tube 10 on the semi-circular plate 63 in sequence. After placement, retract the bidirectional electric push rod 5 to drive the two tube frames 6 to move the duplex stainless steel seamless tube 10 between the rear H-frame plate 3 and the front H-frame plate 4, and adjust the height of the tube frame 6 through the hydraulic cylinder 65 so that the duplex stainless steel seamless tube 10 on the tube frame 6 is coaxial with the corresponding positioning hole 41.

[0085] At this point, the motor is turned forward, driving the electric gripper 9 on the rear H-frame plate 3 to approach the duplex stainless steel seamless tube 10 on the tube rack 6. After the gripper 9 of the electric gripper 9 extends into the interior of one end of the corresponding duplex stainless steel seamless tube 10, the rotation is stopped, allowing the gripper 9 of the electric gripper 9 to open and abut against the inner wall of the duplex stainless steel seamless tube 10, thus completing the fixation of the duplex stainless steel seamless tube 10.

[0086] After fixing the duplex stainless steel seamless tube 10, continue to rotate the motor forward, drive the rear H-frame plate 3 to move to one side of the front H-frame plate 4, so that one end of the duplex stainless steel seamless tube 10 passes into the corresponding positioning hole 41, and stop rotating; let the hydraulic cylinder 65 retract, at this time the semi-circular plate 63 separates from the corresponding duplex stainless steel seamless tube 10, and let the bidirectional electric push rod 5 unfold, so that the two tube frames 6 move out from between the rear H-frame plate 3 and the front H-frame plate 4, and then place the duplex stainless steel seamless tube 10 for new energy vehicles on the two tube frames 6.

[0087] After the two tube supports 6 are removed, the motor continues to rotate forward, driving the rear H-frame plate 3 to move to one side of the front H-frame plate 4, so that one end of the duplex stainless steel seamless tube 10 protrudes from the corresponding positioning hole 41 by the required length, and then stops rotating.

[0088] Then start the drive motor 33, which drives all the gears 91 to rotate, thereby causing all the electric grippers 9 to rotate the corresponding duplex stainless steel seamless tube 10 360 degrees. During the rotation of the duplex stainless steel seamless tube 10, the motor rotates forward, driving the processing head connecting seat 7 to move the cutting blade 8 to one side of the front H-frame plate 4, so that the cutting blade 81 contacts the duplex stainless steel seamless tube 10 on one side of the front H-frame plate 4. Under the rotation of the duplex stainless steel seamless tube 10, the duplex stainless steel seamless tube 10 can be cut.

[0089] After cutting, the second motor reverses and drives the processing head connecting seat 7 to move the cutting blade 8 to the other side of the front H frame plate 4, so that the second cutting blade plate 82 contacts the duplex stainless steel seamless tube 10 on the other side of the front H frame plate 4 and cuts the duplex stainless steel seamless tube 10.

[0090] The cut duplex stainless steel seamless tube 10 will fall onto the guide plate 13, which will guide the cut duplex stainless steel seamless tube 10 to one side; then the above method is used until the entire duplex stainless steel seamless tube 10 is cut; finally, this cycle is repeated.

[0091] When it is necessary to polish the duplex stainless steel seamless tube 10 for new energy vehicles, select a polishing plate that is compatible with the structure of the processing head connecting seat 7. The duplex stainless steel seamless tube 10 can be made to protrude from the positioning hole 2 41 in the above manner. Then, the polishing plate is driven by the motor 2 to contact the duplex stainless steel seamless tube 10 protruding from the positioning hole 2 41 and make the duplex stainless steel seamless tube 10 rotate, so as to polish the duplex stainless steel seamless tube 10.

[0092] When it is necessary to heat the duplex stainless steel seamless tube 10 for new energy vehicles, the duplex stainless steel seamless tube 10 is allowed to protrude from the positioning hole 2 41 in the manner described above. During the process of the duplex stainless steel seamless tube 10 protruding from the positioning hole 2 41, the duplex stainless steel seamless tube 10 can be heated by an electric heating wire.

[0093] All components used in this application are standard parts, and the specific connection methods of each part adopt conventional methods such as threads, bolts, and nesting that are mature in the prior art. All structures use conventional materials in the prior art, and will not be described in detail here.

[0094] In summary, the production process and equipment for corrosion-resistant duplex stainless steel seamless tubes for new energy vehicles, through the overall design, can simultaneously cut multiple duplex stainless steel seamless tubes in a reciprocating cycle during the cutting process, thereby improving the processing efficiency of duplex stainless steel seamless tubes.

[0095] When it is necessary to polish and grind duplex stainless steel seamless tubes for new energy vehicles separately, the cutting blade can be replaced with a grinding plate that matches the structure of the processing head connecting seat; at the same time, the duplex stainless steel seamless tubes for new energy vehicles can be heated separately by electric heating wires; thus, the whole system can perform different processing and production methods on duplex stainless steel seamless tubes for new energy vehicles, making the whole system more flexible and convenient.

[0096] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
