Description

Technical Field

[0001] This invention relates to the technical field of steel processing, specifically to a drawing and rolling apparatus for steel processing. Background Technology

[0002] In the steel processing field, rolling and drawing are two key plastic forming processes: rolling achieves efficient processing of steel with large deformation through the crushing action of rolls, and is suitable for rapid diameter reduction or pre-forming; drawing, on the other hand, stretches steel through dies to achieve higher dimensional accuracy and surface quality. However, rolling alone is difficult to meet the tolerance requirements of precision products (usually above ±0.1mm), while drawing alone is prone to material fracture and low efficiency when processing large deformation. There is an urgent need to develop a drawing and rolling device that can combine the advantages of the two processes to achieve efficient continuous production while taking into account both processing accuracy and material properties.

[0003] Existing steel processing drawing and rolling equipment typically uses two separate devices for drawing and rolling steel, resulting in low operating efficiency and an inability to meet the processing needs of large quantities of steel. Furthermore, the lack of application of cold drawing oil to the steel pipe during drawing causes severe friction between the steel and the die hole wall, affecting the drawing process and the service life of the die, resulting in poor performance.

[0004] To address the above problems, a drawing and rolling device for steel processing is proposed. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Through the cooperation of components such as servo motor C, driving bevel gear, driven bevel gear, screw, straight plate, threaded sleeve B, U-shaped plate, rolling roller, and T-shaped limiting ring, the steel pipe entering the T-shaped limiting ring is rolled. The distance between the front and rear rolling rollers can also be adjusted as needed, resulting in good rolling effect. Through the cooperation of components such as conveying roller, rotating rod, servo motor B, and support frame, the steel pipe is conveyed, which is conducive to the rolling and drawing of the steel pipe.

[0020] 2. Through the cooperation of components such as drive motor, drive gear, rotating gear ring, arc-shaped rotating plate, hydraulic push rod, L-shaped rod, oiling brush, oil dripping pipe and suction pump, lubricating oil can be dripped onto the surface of the steel pipe during the drawing process. At the same time, it can also drive the oiling brush to rotate on the surface of the steel pipe, which is conducive to the more uniform application of lubricating oil to the surface of the steel pipe. This avoids the steel from violently rubbing against the hole wall of the drawing die seat during drawing. The lubricant can reduce the coefficient of friction, avoid the drawing die seat from wearing out too quickly and scratching the material surface, improve the drawing effect and extend the service life of the drawing die seat.

[0021] 3. Through the cooperation of the servo motor A, fixed frame, transmission gear, driven gear, threaded rod, threaded sleeve A, guide plate, guide rod, upright plate, limit frame, hollow plate, moving rod, hinge rod A, hinge rod B and arc-shaped clamping plate, the arc-shaped clamping plates on all four sides can be driven to move inward synchronously, so that they are in contact with the surface of the steel pipe, thereby playing a role in guiding the steel pipe to be transported, and also playing a role in stabilizing the steel pipe during rolling.

[0047] Working principle: During use, the operator can place the steel pipe to be processed on the feed seat 2, extending one end of the steel pipe into the inner cavity of the rolling mill 5. At this time, the servo motor A41 will start. When the servo motor A41 runs, it will drive the transmission gear 42 to rotate. When the transmission gear 42 rotates, it will drive the threaded rod 44 to rotate through the driven gear 43. When the threaded rod 44 rotates, it will drive the threaded sleeve A45 to move to the right. When the threaded sleeve A45 moves to the right, it will drive the hollow plate 46 to move to the right through the moving rod 461. When the hollow plate 46 moves to the right, it will drive the adjacent hinge rod B48 through the hinge rod A47. The steel pipe swings inward, causing the adjacent arc-shaped clamping plate 49 to swing inward as well, thus contacting the surface of the steel pipe and guiding the steel sleeve during transport. Next, the servo motor B62 starts, which in turn drives the conveying roller 6 to rotate via the rotating rod 61, thus transporting the steel pipe to the right. During this rightward transport, the steel pipe enters the T-shaped limiting ring 79, at which point the servo motor C71 starts. The servo motor C71 then drives the driving bevel gear 72 to rotate, which in turn drives the driven bevel gears 73 on the front and rear sides to rotate. This rotation causes the adjacent screw 74 to rotate, which in turn causes the adjacent threaded sleeve B76 to move relative to each other. The relative movement of the threaded sleeve B76, in turn, causes the U-shaped plates 77 on the front and rear sides to move relative to each other via the adjacent upright 761, which in turn causes the adjacent rolling rollers 78 to move relative to each other, thus rolling the passing steel pipe. During this process, the steel pipe continuously moves to the right. Once it has moved to the right and passed through the drawing die seat 8, the hydraulic push rod 95 can be activated. When the hydraulic push rod 95 is in operation, it will position the oil brush 97 to ensure it is in contact with the surface of the steel pipe. Immediately afterwards, the drive motor 91 and the suction pump 99 will rotate, facilitating suction. When pump 99 rotates, it draws lubricating oil from collection tank 10 and delivers it to oil dripping pipe 98, which then drips onto the steel pipe. When drive motor 91 runs, it drives drive gear 92 to rotate. When drive gear 92 rotates, it drives rotating gear ring 93 to rotate. When rotating gear ring 93 rotates, it drives front and rear arc-shaped rotating plates 94 to rotate synchronously. At this time, it also drives oiling brush 97 to rotate and apply oil to the outside of the steel pipe, so that lubricating oil can be evenly applied to the steel pipe. Then, the drawing machine body 30 clamps one end of the steel pipe and pulls it to the right, so that the steel pipe can be drawn under the action of drawing die seat 8.

[0066] The drive motor 91 is bolted to the upper right side of the rolling box 5. Its output shaft is fixedly sleeved with the drive gear 92. The bottom of the drive gear 92 meshes with the rotating gear ring 93. The front and rear sides of the right side of the rotating gear ring 93 are welded with arc-shaped rotating plates 94. The right side of the arc-shaped rotating plates 94 is rotatably mounted on the left side of the drawing die seat 8 via bearings. The top of the front arc-shaped rotating plate 94 is welded with a bearing plate. A hydraulic push rod 95 is installed on the top of the bearing plate. A push plate is welded to the power end of the hydraulic push rod 95. An L-shaped rod 96 is welded to the rear side of the push plate. An oiling brush 97 is installed at the lower end of the L-shaped rod 96.

[0067] A suction pump 99 is installed on the top of the drawing die holder 8. A suction pipe is connected to the front of the suction pump 99, and the lower end of the suction pipe extends into the material collection trough 10. A conduit is connected to the left side of the suction pump 99, and the lower end of the conduit passes through the inner cavity of the oil dripping pipe 98. The oil dripping pipe 98 is fixed to the suction pump 99 by an L-shaped support rod 981. An oil outlet hole is opened at the bottom of the oil dripping pipe 98 for dripping oil onto the steel pipe.

[0068] III. Operating Process of the Device

[0069] (I) Feeding and Positioning

[0070] Place the steel pipe to be processed on the feed seat 2, and push the steel pipe so that its right end passes through the opening of the fixed seat 3 and the rectangular opening of the rolling box 5 in sequence. Start the servo motor A41, and its output shaft drives the transmission gear 42 to rotate. The transmission gear 42 drives the driven gear 43 and the threaded rod 44 to rotate. The rotation of the threaded rod 44 causes the threaded sleeve A45 to move to the right along the guide rod 452, which drives the hollow plate 46 to move to the right through the moving rod 461. When the hollow plate 46 moves to the right, the hinge rod A47 pushes the hinge rod B48 to swing inward, which drives the four arc-shaped clamping plates 49 on both sides to move inward synchronously until they are in contact with the surface of the steel pipe, thus realizing the positioning and guidance of the steel pipe.

[0071] (II) Conveying and Rolling

[0072] Servo motor B62 is started, and its output shaft drives the conveyor roller 6 to rotate via rotating rod 61. The conveyor roller 6 rubs against the surface of the steel pipe, driving the steel pipe to be conveyed to the right at a uniform speed. When the right end of the steel pipe enters the T-shaped limit ring 79, servo motor C71 is started, and its output shaft drives the active bevel gear 72 to rotate, driving the driven bevel gears 73 and screw 74 on the front and rear sides to rotate. The rotation of screw 74 causes threaded sleeve B76 to drive U-shaped plate 77 to move relative to each other along the sliding opening via upright rod 761, adjusting the distance between the front and rear rolling rollers 78 to match the size of the steel pipe. When the steel pipe passes through the rolling rollers 78, the rolling rollers 78 perform rolling processing on the surface of the steel pipe, and the T-shaped limit ring 79 ensures the rolling stability of the steel pipe.

[0073] (III) Oiling and Pulling

[0074] After rolling, the steel pipe continues to be conveyed to the right, passing through the opening on the left side of the drawing die seat 8. The hydraulic push rod 95 is activated, and its power end pushes the L-shaped rod 96 downward, so that the oiling brush 97 contacts the surface of the steel pipe; the suction pump 99 is activated, which draws lubricating oil from the collection tank 10 through the suction pipe and delivers it to the oil dripping pipe 98 through the conduit. The lubricating oil drips onto the surface of the steel pipe through the oil outlet hole; at the same time, the drive motor 91 is activated, and its output shaft drives the drive gear 92 to rotate, which drives the rotating gear ring 93 and the arc-shaped rotating plate 94 to rotate. The arc-shaped rotating plate 94 drives the oiling brush 97 to rotate circumferentially along the surface of the steel pipe, so as to evenly apply the lubricating oil to the surface of the steel pipe.

[0075] When the right end of the steel pipe extends out of the drawing die seat 8, the drawing machine body 30 clamps the right end of the steel pipe, and starts the drawing machine body 30 to pull the steel pipe to the right. The steel pipe completes the drawing and forming under the action of the drawing die seat 8. The whole process realizes continuous operation of rolling and drawing.

[0076] IV. Beneficial Effects of the Examples

[0077] 1. It integrates rolling and drawing functions, eliminating the need for separate equipment operation, thereby improving steel processing efficiency and meeting the demand for large-volume steel processing.

[0078] 2. The positioning component adaptively clamps steel pipes of different diameters through an arc-shaped clamping plate, ensuring the stability of conveying and rolling and improving processing accuracy.

[0079] 3. The rolling assembly can adjust the roller spacing via servo motor C, adapting to the rolling of steel pipes of different specifications, and has strong versatility.

[0080] 4. The coating component uses an oil dripping tube to drip oil and a circumferentially rotating oiling brush to achieve uniform coating of lubricating oil, reduce the coefficient of friction between the steel and the die hole wall during drawing, reduce die wear and material scratches, and extend the service life of the die.

[0081] 5. Each component is automated through transmission structures such as motors, gears, and screws, reducing the intensity of manual operation and improving processing consistency.
