Description

Technical Field

[0001] This invention relates to the field of stainless steel pipe production technology, and in particular to a seamless stainless steel pipe outer surface drawing process and processing device. Background Technology

[0002] Metal brushing is a manufacturing process that repeatedly uses sandpaper to scrape lines onto an aluminum plate. The main steps consist of three parts: degreasing, sanding, and washing. During the brushing process, a special film technology applied after anodizing creates a film layer containing the metal's components on the metal surface, clearly revealing each fine brush mark and giving the matte metal a subtle, hair-like sheen. In recent years, an increasing number of products have adopted metal brushing for their metal casings, achieving both aesthetic appeal and corrosion resistance, thus combining fashion and technological elements. This is one of the reasons for the process's popularity.

[0003] Chinese Patent Announcement No.: CN 217942931 U, Announcement Date: December 2, 2022. This utility model discloses a stainless steel pipe outer surface wire drawing processing device, including a bearing base, two support plates, a rotating positioning component, and a limiting component that can be inserted into both ends of a steel pipe to fix the steel pipe. The two support plates are respectively movably arranged on the left and right sides of the top surface of the bearing base. The support plates have through holes. The two parts of the rotating positioning component are respectively disposed on the side walls of the two through holes. The two parts of the limiting component pass through the two through holes and can rotate in the corresponding through holes. The two parts of the rotating positioning component abut against the two parts of the limiting component. By inserting the two main bodies into both ends of the steel pipe, the abutting parts are pressed against the inner side walls of both ends of the steel pipe by the driving part to achieve the effect of fixing the steel pipe. The shortcomings of this technical solution are: 1. The main support supports both ends of the tube, so the tube is still deformed when the stress is uneven, especially in the middle; 2. The tube is drawn from the side and flipped, which reduces efficiency and causes misalignment.

[0004] In summary: the equipment suffers from drawbacks such as easy deformation of the steel pipe body, low pulling efficiency, and low precision during processing. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing technology in the processing of steel pipes, such as easy deformation of the steel pipe body, low drawing efficiency and accuracy, and provides a seamless stainless steel pipe outer surface drawing process and processing device that prevents steel pipe body deformation and improves drawing efficiency and accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seamless stainless steel pipe outer surface wire drawing processing device includes a base, a fixed bracket, a movable seat, and a pushing assembly connected to the base. The movable seat and the pushing assembly are both movably connected to the base. There are two movable seats with relative movement directions. A main bracket and a secondary bracket are detachably connected to the fixed bracket. The main bracket is placed between the two movable seats. Secondary brackets are provided on both sides of the two movable seats. A wire drawing assembly and a waste collection assembly are detachably connected to each movable seat. The wire drawing assembly, the main bracket, and the secondary bracket are all provided with pipe body connection holes. Inner support rollers are inserted into the pipe body connection holes. A cooling groove is provided on the movable seat.

[0008] A fixed bracket is installed on the base to connect and support the main bracket and the secondary bracket. The main bracket and the secondary bracket support and connect the steel pipe body. The movable seat, along with the wire drawing assembly and the waste collection assembly, is installed on the base. The cooling tank on the movable seat holds coolant to facilitate timely cooling of the wire drawing assembly. The movable seat can move on the base, allowing the wire drawing assembly and the waste collection assembly on the movable seat to draw the steel pipe body installed on the main bracket and the secondary bracket and collect the waste generated after wire drawing. This enables the equipment to draw wire efficiently, and the repeated flipping and moving of the steel pipe body affects the wire drawing effect and efficiency. At the same time, the relative movement of the two wire drawing assemblies on the two movable seats can further improve the efficiency of wire drawing and reduce the wire drawing time of individual structures, thereby shortening the service life. In addition, the coolant in the cooling tank on the movable seat facilitates efficient cooling of the wire drawing assembly to reduce wear and tear. The waste collection function provides on-site collection of waste, making the equipment suitable for efficient continuous production. The wire drawing assembly, main bracket, and slave brackets all have tube connection holes on the same central axis, allowing the steel tube to be moved within the wire drawing assembly for grinding and wire drawing. The tube connection holes include inner support rollers, which are inserted into the tube body to support the steel tube, ensuring the tube maintains its shape and does not deform under external forces such as clamping and wire drawing. The main bracket and two slave brackets form a three-section support connection, balancing the force on the steel tube, reducing deformation, and enhancing stability for easier wire drawing. It facilitates wire drawing from the end of the steel tube, making the process comprehensive and convenient. The detachable main bracket, slave brackets, wire drawing assembly, and waste collection assembly allow the equipment to be used with steel tubes of different sizes, improving its practicality. The equipment achieves efficient and comprehensive wire drawing, reduced structural loss, immediate waste collection, facilitating continuous production, high strength to ensure the steel tube does not deform, and high applicability and practicality.

[0009] Preferably, the tube body connection hole includes a first connection hole, and the wire drawing assembly includes a wire drawing plate, a positioning block, and a fixing screw.

The holes on the wire drawing plate for placing the steel pipe and inner support roller are the first connection holes in the pipe connection hole. The positioning block connects the wire drawing plate to the moving base through the positioning groove. The positioning grooves on the mounting holes in the moving base are of different sizes to position the connection between the wire drawing plate and the moving base, so that the wire drawing plates on both sides can be connected to the moving base accordingly. The foolproof design prevents the lines drawn by the grinding teeth on the two wire drawing plates from not coinciding, thereby further improving the structural connection accuracy and ensuring the wire drawing effect. In addition, the wire drawing plate is further fixed to the moving base by the fixing screw to further improve the structural connection strength and operation accuracy. This achieves the effect of improving the efficiency and strength of the structure and improving the accuracy of the wire drawing operation.

[0010] Preferably, the pipe body connection hole includes a second connection hole, the bracket includes a movable block and a first connecting plate, the movable block is connected to a nearby movable seat, the fixed bracket is provided with a sliding groove, one end of the movable block is slidably connected to the sliding groove, the other end of the movable block is provided with a first mounting groove, one end of the first connecting plate is inserted into the first mounting groove, the second connection hole is located at the other end of the first connecting plate, the movable block is connected with a first rotating rod, the first rotating rod is provided with a first locking piece, the first locking piece is provided with a first rotating hole, the first rotating rod is inserted into the first rotating hole, the first locking piece is rotatably connected to the first connecting plate, the first locking piece is located at the opening of the first mounting groove, and the moving direction of the movable block in the sliding groove is perpendicular to the moving direction of the first connecting plate inserted into the first mounting groove. The movable block slides in a groove on the fixed bracket. The movement of the bracket is achieved through the linkage between the movable block and the movable seat, thus simplifying the structure. Connecting hole two in the pipe body is placed on connecting plate one. Connecting plate one is quickly connected to the movable block via an insertion joint. Connecting plate one is inserted into mounting groove one and connected to the movable block. After insertion, locking piece one is rotated to fix connecting plate one and prevent it from dislodging from mounting groove one. The direction of movement of the movable block in the groove is perpendicular to the direction of movement of connecting plate one inserted into mounting groove one. When connected plate one is under force, it is further prevented from dislodging. This achieves the effects of convenient installation, disassembly, replacement, and maintenance, as well as high structural connection strength.

[0011] Preferably, the tube body connection hole includes a third connection hole, and the main bracket includes a fixing block and a second connecting plate. One end of the fixing block is movably connected to the fixing bracket, and the other end of the fixing block is provided with a second mounting groove. One end of the second connecting plate is inserted into the second mounting groove. The third connection hole is located at the other end of the second connecting plate. A rotating rod is connected to the second connecting plate, and the rotating rod is provided with a second locking piece. The second locking piece is provided with a second rotating hole, and the rotating rod is inserted into the second rotating hole. The second locking piece is rotatably connected to the second connecting plate, and the second locking piece is located at the opening of the second mounting groove. The fixing block is movably connected to the fixing bracket, allowing the fixing block to be fixed and moved on the fixing bracket, facilitating the handling of the tube body portion connected to the main bracket. The third connection hole in the tube body connection hole is located on the second connecting plate, and the second connecting plate is quickly connected to the fixing block by insertion. The second connecting plate is inserted into the second mounting groove and connected to the fixing block. After insertion and connection, the second connecting plate is fixed by rotating the second locking piece to prevent the second connecting plate from falling out of the second mounting groove. This achieves the effects of convenient installation, disassembly, replacement and maintenance, and high structural connection strength.

[0012] Preferably, the waste collection assembly includes a collection frame and a support block. The collection frame has an upper limit hole, a movable seat is inserted into the upper limit hole, and the movable seat has a slot. The support block is inserted into the slot, and the collection frame abuts against the support block. In the collection assembly, the collection frame is mounted on the movable seat in a circular, U-shaped arrangement, resulting in a large collection range and good debris collection effect. The collection frame is connected to the movable seat via a sleeve for easy removal. The support block protrudes from the movable seat surface by engaging with the slot, thus supporting the collection frame and ensuring its stability. This achieves a stable structural connection, easy disassembly, and efficient and comprehensive waste collection and disposal to meet the needs of continuous production.

[0013] Preferably, the connecting hole one includes a guide surface and a grinding surface. The grinding teeth are connected to the grinding surface. The guide surface has a frustum shape, with the smaller diameter end of the guide surface connecting to the grinding surface and the larger diameter end facing outwards. The collecting frame has an inlet, which is positioned on the side of the collecting frame facing the connecting hole one. Both ends of the connecting hole one have frustum-shaped guide surfaces, and the middle grinding surface is cylindrical and connected to the grinding teeth. The frustum-shaped guide surface facilitates the guidance of debris into the inlet of the collecting frame for collection. Simultaneously, the frustum-shaped structure facilitates the guidance of the steel pipe body into the grinding surface. This achieves the effects of improving collection efficiency and comprehensiveness, and facilitating wire drawing operations.

[0014] Preferably, the pusher assembly includes a mounting base and a push rod. The lower end of the mounting base is movably connected to the base, and the push rod is connected to the upper end of the mounting base. A fixing block is engaged with a sliding groove. A limiting hole is provided on the fixing bracket, which communicates with the sliding groove. A locking rod is inserted into the limiting hole and is slidably connected to the limiting hole via the push rod. A locking groove adapted to the locking rod is provided on the fixing block. The pusher assembly includes a mounting base and a push rod. The mounting base is connected to the base and slides on the base. The push rod is connected to the mounting base to stabilize the force applied by the push rod. The fixing block is engaged with the sliding groove and fixed to the fixing bracket by the locking rod to prevent movement, thus facilitating wire drawing. At the same time, the locking rod can move in the limiting hole and move in and out of the locking groove by being pushed by the push rod, so that the fixing block can move in the sliding groove within the fixing bracket under external force, facilitating the wire drawing plate to draw the undrawn part in the middle of the steel pipe. By switching the state of the fixing block, the structural stability and operational flexibility are ensured.

[0015] Preferably, the locking rod has a movable hole with a guide slope on its wall. The guide slope is arranged opposite to the push rod. A first elastic mechanism and a second elastic mechanism are connected to the fixed bracket. The first elastic mechanism is connected to the locking rod, and the second elastic mechanism is connected to the fixed block. The movable hole allows the push rod to be pulled out of the locking groove when it enters through the guide slope. Simultaneously, after exiting the movable hole, the locking rod is reset by the first elastic mechanism and re-enters the fixed block, which is reset by the second elastic mechanism. This improves the automation level and stability of the structure.

[0016] Preferably, the first connecting plate is provided with a locking rod, a top block, and a sliding hole. The sliding hole is connected to the second connecting hole, and the locking rod is inserted into the sliding hole.

The sliding hole is connected to the second connecting hole, and the locking rod is inserted into the sliding hole. The second connecting plate is equipped with a telescopic mechanism, and the top block is connected to the telescopic mechanism. The locking rod is slidably connected to the sliding hole through the top block. The first top block on the connecting plate is moved by the power of the telescopic mechanism, causing the top block to push the locking rod and press the pair of steel pipes onto the connecting plate. Similarly, the second top block on the connecting plate is moved by the power of the telescopic mechanism, causing the top block to push the locking rod and press the steel pipes onto the connecting plate. This further secures the middle of the steel pipe when switching between the wire drawing plate and the ends of the steel pipe, and further secures the sides of the pair of steel pipes on the connecting plate when the wire drawing plate is pulling the middle of the steel pipe. This achieves the effect of improving structural stability and wire drawing quality.

[0017] This invention also provides a seamless stainless steel tube outer surface wire drawing process, including the stainless steel tube to be processed, specifically including the following steps:

[0018] S1: Loading: Insert the inner support rod into the stainless steel tube. The stainless steel tube passes through the connection hole three on the main bracket, so that the middle part is placed in the connection hole three and the two sides face the connection hole one.

[0019] S2: Side wire pulling: Locking rod two locks the middle of the stainless steel tube, and the two moving seats move relative to each other to pull the wire from the end of the stainless steel tube until they move to the main bracket and stop.

[0020] S3: Middle wire pulling: Move one side of the moving seat in the opposite direction, unlock the fixing block through the locking rod, move the other side of the moving seat, lock the stainless steel tube with the locking rod on the moving connecting plate, move the other moving seat to push away from the main bracket and pull the middle of the stainless steel tube, and completely reset the moving seats on both sides.

[0021] S: Unloading: Unlock the second locking rod, remove the stainless steel tube from the main bracket, and remove the inner support roller from the stainless steel tube to end the wire drawing process.

[0022] Insert the inner support roller into the stainless steel tube, so that the outer surface of the inner support roller is in contact with the inner wall of the stainless steel tube, providing full support for the stainless steel tube. Pass the stainless steel tube through the connecting hole three on the tube connection hole of the main bracket, so that the middle part of the stainless steel tube is placed in the connecting hole three, thereby supporting and connecting the stainless steel tube. The two sides of the stainless steel tube face the connecting holes one on the two movable seats. Locking rod two locks the stainless steel tube: Activate telescopic mechanism two, so that top block two moves to press locking rod one against the stainless steel tube, thereby preventing the stainless steel tube from rotating or moving on the main bracket. Activate the linear guide rails on the two movable seats, so that the two movable seats move relative to each other. The stainless steel tube enters the connecting hole one on the wire drawing plate. As the movable seats move, the surface of the stainless steel tube is ground and drawn from the end of the stainless steel tube. The two ends are drawn simultaneously and move relative to each other until the movable seats move to the main bracket and stop. Move one movable seat in the opposite direction, so that the movable seat is withdrawn a certain distance, but the connecting plate one on this side is not completely withdrawn from the stainless steel tube and stops. By activating telescopic mechanism one on the connecting plate one on this side, top block one pushes locking rod one to lock the stainless steel tube. The movable mounting base moves the push rod, which pushes the locking rod through the guide ramp and inserts it into the other side of the movable hole, causing the locking rod to disengage from the locking groove and unlock the fixing block. Moving the other movable base allows the wire-drawing plate on the other movable base to continue drawing the middle of the stainless steel tube. After completion, the entire stainless steel tube is wire-drawn. Resetting the mounting base allows the locking rod to re-enter the locking groove and lock the fixing block under the elastic mechanism. Loosening the first locking rod on connecting plate one and tightening the second locking rod on connecting plate two, then fully resetting both movable bases completes the wire drawing process. Unlocking the second locking rod allows the stainless steel tube to be removed from the main bracket, and the inner support roller to be removed from the stainless steel tube, ending the wire drawing process. This achieves strong support and fixation of the stainless steel tube, eliminates the need to flip the tube during wire drawing, and enables highly efficient wire drawing.

[0023] The beneficial effects of this invention are: efficient and comprehensive wire drawing; reduced structural loss; immediate waste collection; convenient for continuous production; high strength to ensure the steel pipe body does not deform; high applicability and practicality; improved structural efficiency and strength; improved wire drawing operation accuracy; convenient installation, disassembly, replacement and maintenance; improved material collection efficiency and comprehensiveness; improved structural automation and stability, thereby improving wire drawing quality.

The top block 2 moves within the limiting frame 2 and pushes the locking rod 2, thereby increasing the thrust strength and improving the structural stability.

[0049] The present invention also provides a seamless stainless steel tube outer surface wire drawing process, including a stainless steel tube 48 to be processed, specifically including the following steps:

[0050] S1: Loading: Insert the inner support rod 10 into the stainless steel tube 48. The stainless steel tube 48 passes through the connection hole three on the main bracket 5, so that the middle part is placed in the connection hole three and the two sides face the connection hole one 12.

[0051] S2: Pulling wires on both sides: Locking rod 2 locks the middle part of stainless steel tube 48, and the two moving seats 3 move relative to each other to pull wires from the end of stainless steel tube 48 until they move to the main bracket 5 and stop.

[0052] S3: Middle wire pulling: Move one side of the moving seat 3 in the opposite direction, unlock the fixing block 23 through the locking rod 38, move the other side of the moving seat 3, lock the stainless steel tube 48 with the locking rod 44 on the moving connecting plate 12, move the other moving seat 3 to push away from the main bracket 5 and pull the stainless steel tube 48 in the middle, and completely reset the moving seats 3 on both sides.

[0053] S4: Unloading: Unlock the second locking rod, remove the stainless steel tube 48 from the main bracket 5, and remove the inner support roller 10 from the stainless steel tube 48 to end the wire drawing process.

[0054] The specific operation is as follows: Insert the inner support roller 10 into the stainless steel tube 48, so that the outer surface of the inner support roller 10 is in contact with the inner wall of the stainless steel tube 48, providing full support for the stainless steel tube 48. Pass the stainless steel tube 48 through the connecting hole three of the tube body connecting hole 9 on the main bracket 5, so that the middle part of the stainless steel tube 48 is placed in the connecting hole three, thereby providing support and connection for the stainless steel tube 48. The two sides of the stainless steel tube 48 face the connecting holes one 12 on the two side moving seats 3.

[0055] Locking rod two locks stainless steel tube 48: Activate telescopic mechanism two, causing top block two to move and press locking rod one against stainless steel tube 48, thereby preventing stainless steel tube 48 from rotating or moving on main bracket 5. Activate the linear guide rails on the two moving seats 3, causing the two moving seats 3 to move relative to each other. Stainless steel tube 38 enters the connecting hole 12 on the wire drawing plate 13. As the moving seat 3 moves, the surface of stainless steel tube 48 is ground and wire-drawn from the end of stainless steel tube 48. Both ends are wire-drawn and move relative to each other until the moving seat 3 moves to the main bracket 5 and stops. Move one side of the moving seat 3 in the opposite direction, causing the moving seat 3 to retract a certain distance, but the connecting plate 18 on this side does not completely retract from the stainless steel tube 48 and stops. Activate telescopic mechanism 47 on the connecting plate 18 on this side, causing top block 45 to push locking rod 44 to lock stainless steel tube 48.

[0056] The movable mounting base 35 is moved so that the push rod 36 moves from the guide ramp 41 to push the locking rod 38 and insert it into the other side of the movable hole 40, causing the locking rod 38 to leave the locking groove 39 and thus unlocking the fixing block 23. The movable base 3 on the other side is moved so that the wire drawing plate 13 on the other movable base 3 continues to draw the middle of the stainless steel tube 48. After completion, the entire stainless steel tube 48 is drawn. The mounting base 35 is reset so that the locking rod 38 re-enters the locking groove 39 under the elastic mechanism 1 42 to lock the fixing block 23. The locking rod 1 44 on the connecting plate 1 18 is released, and the locking rod 2 on the connecting plate 2 24 is pressed. Then the movable bases on both sides are fully reset to complete the wire drawing. The locking rod 2 is unlocked, the stainless steel tube 48 is removed from the main bracket 5, and the inner support roller 10 is removed from the stainless steel tube 48, ending the wire drawing process.
