Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip processing technology, specifically a heat dissipation structure for stainless steel strip processing. Background Technology

[0002] Stainless steel strip is a narrow and long steel plate, usually an extension of ultra-thin stainless steel sheet, mainly used to meet the needs of different industrial sectors in the industrial production of various metal or mechanical products.

[0003] Heat dissipation is a critical step in the processing of stainless steel strips. While water spray cooling is a common heat dissipation method that can quickly reduce the temperature, it also brings a series of process challenges.

[0004] When the surface of a high-temperature steel strip comes into contact with cooling water, the instantaneously generated steam forms an unstable vapor film on the metal surface. This vapor film effect is like covering the steel strip with an uneven heat insulation blanket, resulting in significant differences in the cooling rate of different areas. This uneven cooling not only causes an imbalance in the internal stress distribution of the material at the microscopic level, but also manifests as deformation defects such as wavy edges or warping during subsequent processing.

[0005] The problem of water stains stems from the unique properties of stainless steel surfaces. When water droplets evaporate, the trace minerals they carry leave ring-shaped marks on the smooth metal surface. These marks can evolve into stubborn oxide spots during subsequent annealing processes. Even more problematic is that chloride ions in certain types of water can react with chromium in stainless steel, forming pitting corrosion sources. These tiny corrosion points pose a risk to the long-term use of the product in humid environments. Utility Model Content

[0006] The purpose of this utility model is to provide a heat dissipation structure for processing stainless steel strips. It has the advantages of facilitating heat dissipation for stainless steel strips of different thicknesses, eliminating the need for direct water spraying, preventing uneven cooling and water stains, and improving heat dissipation efficiency. It solves the problem that when processing stainless steel strips, heat dissipation is usually achieved by spraying water, which causes a "vapor film effect" (leading to uneven local cooling) and results in water stains or oxidation spots on the stainless steel strip.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for processing stainless steel strip, comprising a workbench and a steel strip body. A long plate is fixed on one side of the upper surface of the workbench, and movable plates are movably connected to the upper and lower ends of one side of the long plate. A rotating rod is rotatably connected to one side of the movable plate, and a copper alloy roller is fixed to one side of the rotating rod. A water inlet pipe is rotatably connected to one side of the copper alloy roller, and a water outlet pipe is rotatably connected to the other side of the copper alloy roller. The steel strip body passes through the space between the upper and lower copper alloy rollers.

[0008] Preferably, four pillars arranged in a rectangular array are fixed to the lower surface of the worktable. The four pillars support the worktable, making the entire device stable.

[0009] Preferably, a through slot is provided on one side of the upper surface of the worktable. The through slot facilitates the installation of a motor at the bottom end of the long plate.

[0010] Preferably, the long plate has long grooves at both the top and bottom ends on one side, and a connecting block is inserted into the long groove. The upper surface of the connecting block has a threaded hole. The long plate has round holes at both the top and bottom ends, and motors are fixed to both ends of the long plate. The bottom end of the drive shaft of the motor extends into the round hole, and a screw is fixed to the bottom end of the drive shaft. The bottom end of the screw passes through the threaded hole and is threadedly connected. A movable plate is fixed to one side of the connecting block. The drive shaft of the motor fixes the screw, providing power for its rotation. This allows the connecting block, movable plate, and copper alloy roller to move up and down as needed, facilitating heat dissipation for steel strips of different thicknesses.

[0011] Preferably, the width of the long groove in the long plate matches the width of the connecting block. By matching the width of the long groove with the width of the connecting block, the long groove can limit the rotation of the connecting block, preventing the screw from rotating. The connecting block rotates with the screw, facilitating the up-and-down movement of the connecting block and the copper alloy roller.

[0012] Preferably, the copper alloy roller has a circular groove inside. A mounting hole is formed at the upper end of one side of the copper alloy roller, and a sealing shaft is installed in the mounting hole. One side of the water inlet pipe extends into the sealing shaft and is rotatably connected. A valve is installed on one side of the outer wall of the water inlet pipe, and a flexible hose is sleeved at the top of the water inlet pipe. A second mounting hole is formed at the lower end of the other side of the copper alloy roller, and a second sealing shaft is installed in the mounting hole. One side of the water outlet pipe extends into the sealing shaft and is rotatably connected. A valve is installed on one side of the outer wall of the water outlet pipe, and a flexible hose is sleeved at the bottom of the water outlet pipe. By having the water inlet pipe extend into the sealing shaft and be rotatably connected, and the water outlet pipe extend into the sealing shaft and be rotatably connected, the water inlet and outlet pipes can remain stationary when the copper alloy roller rotates. This facilitates the introduction of cooling water into the circular groove, promoting heat dissipation for the steel strip body. The water inlet and outlet pipes also facilitate the circulation of cooling water within the circular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a long plate fixed to one side of the upper surface of a workbench. Movable plates are connected to the upper and lower ends of one side of the long plate. A rotating rod is rotatably connected to one side of the movable plate, and a copper alloy roller is fixed to one side of the rotating rod. When heat dissipation of the steel strip body is required, the steel strip is passed between the upper and lower copper alloy rollers. The motor is then started, causing the screw to rotate and the upper and lower copper alloy rollers to move. The upper copper alloy roller is in contact with the upper surface of the steel strip body, and the lower copper alloy roller is in contact with the lower surface of the steel strip body, thus achieving the effect of facilitating heat dissipation for stainless steel strips of different thicknesses.

[0015] 2. This utility model uses a copper alloy roller with a water inlet pipe rotatably connected to one side and a water outlet pipe rotatably connected to the other side. The steel strip body passes between the upper and lower copper alloy rollers. When it is necessary to dissipate heat from the steel strip body, cooling water is introduced into the water inlet pipe as the copper alloy roller rotates. The cooling water entering the circular groove is then discharged through the water outlet pipe, achieving the effect of not needing to directly spray water for heat dissipation, preventing uneven cooling and water stains, and improving the heat dissipation effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7 The present invention provides two embodiments:

[0026] Example 1: A heat dissipation structure for processing stainless steel strip includes a workbench 2 and a steel strip body 4. A long plate 3 is fixed on one side of the upper surface of the workbench 2. Movable plates 13 are movably connected to the upper and lower ends of one side of the long plate 3. A rotating rod 14 is rotatably connected to one side of the movable plate 13. A copper alloy roller 6 is fixed to one side of the rotating rod 14. A water inlet pipe 15 is rotatably connected to one side of the copper alloy roller 6. A water outlet pipe 18 is rotatably connected to the other side of the copper alloy roller 6. The steel strip body 4 passes through the space between the upper and lower copper alloy rollers 6.

[0027] Four pillars 1 arranged in a rectangular array are fixed on the lower surface of the workbench 2;

[0028] A through groove 7 is provided on one side of the upper surface of the workbench 2;

[0029] Long slots 11 are provided at the top and bottom ends of one side of the long plate 3. A connecting block 9 is inserted into the long slots 11. A threaded hole 10 is provided on the upper surface of the connecting block 9. Round holes 12 are provided at the top and bottom ends of the long plate 3. Motors 5 are fixed at the top and bottom ends of the long plate 3. The bottom end of the drive shaft of the motor 5 extends into the round hole 12. A screw 8 is fixed at the bottom end of the drive shaft of the motor 5. The bottom end of the screw 8 passes through the threaded hole 10 and is threadedly connected. A movable plate 13 is fixed on one side of the connecting block 9.

[0030] The drive shaft of the motor 5 is fixed with a screw 8, which provides power for the rotation of the screw 8, so that the upper and lower copper alloy rollers 6 can move as needed. The two copper alloy rollers 6 can respectively fit against the upper and lower surfaces of the steel strip body 4, which facilitates heat dissipation treatment for steel strip bodies 4 of different thicknesses.

[0031] Motor 5 is a servo motor, an actuator that converts voltage signals into torque and speed. Its core structure includes the motor body, sensors, and a control loop. The motor body typically uses either a DC or AC motor. AC servo motors have stators with excitation and control windings spaced 90° apart electrically, and the rotor is often a squirrel-cage or non-magnetic cup-shaped structure for rapid response. DC servo motors include components such as an armature, permanent magnets, and a commutator. Brushless DC motors use electronic commutation devices to replace traditional brushes, improving reliability. Sensors detect rotor position and speed in real time, converting mechanical motion into pulse signals that are fed back to the control loop. The control loop processes the feedback signals using operational amplifiers, proportional-integral controllers, and other components. After comparing the feedback signals with the setpoint, it outputs adjustment commands, which are then converted into motor drive signals by the driver to form a closed-loop control.

[0032] The working principle is based on electromagnetic induction and closed-loop feedback mechanism. When a voltage with a phase difference is applied to the control winding and the excitation winding, the two-phase winding generates a rotating magnetic field. The rotor conductors cut the magnetic field lines to generate an induced current and form an electromagnetic torque, which drives the rotor to rotate synchronously.

[0033] An electronic synchronizer enables the two motors 5 to rotate synchronously. The synchronizer works by monitoring the speed signals of the two motors 5 in real time. When a speed difference is detected, the controller dynamically adjusts the voltage, current, or frequency of one motor 5 to match its speed with the other. This synchronous control relies on speed feedback provided by an encoder or Hall effect sensor, combined with a PID algorithm for closed-loop regulation, ensuring that the two motors 5 maintain synchronous operation even when the load changes.

[0034] The width of the long slot 11 in the long plate 3 matches the width of the connecting block 9;

[0035] In this embodiment, when it is necessary to dissipate heat from the processed stainless steel strip, the processed stainless steel strip is transported between the upper and lower copper alloy rollers 6. Then, the motor 5 is started, causing the screw 8 to rotate. The connecting block 9, the moving plate 13, and the copper alloy rollers 6 can move up and down as needed, so that the upper copper alloy roller 6 is in contact with the upper surface of the steel strip body 4, and the lower copper alloy roller 6 is in contact with the lower surface of the steel strip body 4, thus achieving the effect of facilitating heat dissipation for stainless steel strips of different thicknesses.

[0036] Example 2:

[0037] The copper alloy roller 6 has a circular groove 21 inside. A mounting hole 23 is opened at the upper end of one side of the copper alloy roller 6. A sealing shaft 22 is installed in the mounting hole 23. One side of the water inlet pipe 15 extends into the sealing shaft 22 and is rotatably connected. A valve 16 is installed on one side of the outer wall of the water inlet pipe 15. A flexible hose 17 is sleeved on the top end of the water inlet pipe 15. A mounting hole 24 is opened at the lower end of the other side of the copper alloy roller 6. A sealing shaft 25 is installed in the mounting hole 24. One side of the water outlet pipe 18 extends into the sealing shaft 25 and is rotatably connected. A valve 29 is installed on one side of the outer wall of the water outlet pipe 18. A flexible hose 20 is sleeved on the bottom end of the water outlet pipe 18.

[0038] One side of the inlet pipe 15 extends into the sealing shaft 22 and is rotatably connected, and the other side of the outlet pipe 18 extends into the sealing shaft 25 and is rotatably connected, so that when the copper alloy roller 6 rotates, the inlet pipe 15 and the outlet pipe 18 will not rotate with it, which facilitates the introduction and discharge of cooling water.

[0039] In this embodiment, when heat dissipation is required for the processed stainless steel strip, the stainless steel strip is directly conveyed between the upper and lower copper alloy rollers 6, and cooling water is introduced into the hose 17. The cooling water enters the circular groove 21 of the copper alloy roller 6 through the inlet pipe 15, and then exits through the outlet pipe 18 and the hose 20. After being cooled, the discharged cooling water is finally introduced into the circular groove 21 through the hose 17. This achieves the effect of eliminating the need for direct water spraying for heat dissipation, preventing uneven cooling and water residue, and improving heat dissipation performance.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
