Description

Technical Field

[0001] The present application relates to the field of metal processing equipment technology, and in particular, to a metal strip coiling device for cold-drawn bar production. Background Art

[0002] Since the mid-20th century, the GH2132 superalloy has become a highly regarded research focus in the field of materials science. Its initial R & D intention was to solve the material failure problems of core components such as aero-engine turbine blades and combustion chambers under extreme working conditions of high temperature and high pressure. In the early stage, this alloy was based on nickel, and by carefully proportioning and adding elements such as chromium (Cr), molybdenum (Mo), titanium (Ti), and aluminum (Al), the high-temperature strength and oxidation resistance of the alloy were effectively optimized, and a strengthening system centered on the γ' phase (Ni3(Al,Ti)) was constructed. With the continuous progress of materials science, in the late 20th century, by further introducing elements such as niobium (Nb) and cobalt (Co) into the GH2132 alloy, its creep resistance and corrosion resistance were significantly improved, and the composition range was precisely regulated to nickel (55 - 60%), chromium (19 - 22%), molybdenum (8 - 10%), and the contents of trace carbon (C) and silicon (Si) were strictly controlled to further optimize the processing characteristics.

[0003] In the fine production process of GH2132 alloy cold-drawn bars, a series of rigorous technological steps are closely linked, including smelting steel billets, preheating and heating square billets, rolling into coils, coiling the coils, pickling the coil bars to remove oxide scales, drawing the coil bars to improve dimensional accuracy and mechanical properties, annealing treatment to eliminate internal stress, and finally straightening and polishing to ensure the surface finish and dimensional accuracy of the product. Among them, coil coiling, as a key step connecting the front and back processes, its efficiency and quality are directly related to the smoothness of the entire production process and the quality of the final product.

[0004] However, in the coiling process, traditional coiling devices mostly use winding rollers to fix and wind metal strips. This method has significant drawbacks: the strip is easily tightened on the outer wall of the winding roller during the coiling process, resulting in a sharp increase in friction force, which not only increases the wear degree of the equipment, but also makes it extremely difficult to unload the strip. Moreover, the friction between the equipment and the strip during unloading further exacerbates the damage to the strip surface, seriously affecting the processing efficiency and surface quality of the metal strip. Summary of the Invention

[0005] In order to facilitate the operator to unload the metal strip coil on the coiling device and improve the processing efficiency of the metal strip, the present application provides a metal strip coiling device for cold-drawn bar production.

[0008] By adopting the above technical scheme, the driving component drives the winding frame to rotate to achieve the winding effect of the metal strip. The baffle and the baffle rod are located on both sides of the winding frame to limit the metal strip roll on the rotating frame. When unloading is required, the operator drives the baffle rod to flip through the second driving component to release the limiting effect on the metal strip roll, and then drives the winding frame to shrink through the first control component to release the supporting effect on the inner circle of the metal strip roll, so as to facilitate the unloading of the metal strip roll, which is beneficial to improve the processing efficiency of the metal strip roll and can reduce the wear of the metal strip roll during unloading.

[0010] By adopting the above technical solution, the operator drives the second sprocket to rotate through the motor, and under the transmission action of the chain, the first sprocket, the rotating frame and the winding frame are driven to rotate, thereby achieving the winding effect of the metal strip.

[0011] Optionally, the first control component includes a rotating shaft axially passing through the rotating frame, a control unit for controlling the axial sliding of the rotating shaft is arranged on the cantilever, a first connecting rod is hinged on the support plate, an end of the first connecting rod away from the support plate is hinged on the rotating shaft, a second connecting rod is hinged on the rotating frame, a sliding seat is hinged on the second connecting rod, the sliding seat is slidably arranged on the support plate, and the middle position of the first connecting rod is hinged to the middle position of the second connecting rod.

[0012] By adopting the above technical solution, the control unit drives the rotating shaft to move relative to the rotating frame, and then drives the first connecting rod and the second connecting rod to flip over each other, thereby controlling each support plate to move closer to or away from the rotating frame to achieve expansion or contraction of the winding frame.

[0013] Optionally, the control unit includes a first electric push rod fixedly connected to the frame. A rotating seat is rotatably connected to the piston rod of the first electric push rod, and the rotating seat is rotatably connected to the rotating shaft.

[0015] Optionally, the second control component includes a crank fixedly connected to the stop rod. The stop rod is hinged to the rotating frame, a linkage rod is hinged to the crank, and the linkage rod is hinged to the rotating shaft.

[0016] By adopting the above technical solution, when the rotating shaft axially moves relative to the rotating frame, it can drive the linkage rod to push the crank to flip, thereby realizing the flip control of the stop rod, which is used for limiting the metal strip coil, facilitating the winding of the metal strip, or releasing the limit on the metal strip coil for blanking.

[0017] Optionally, a top push rod is movably arranged on the rotating frame. A first movable rod and a second movable rod parallel to each other are hinged to the top push rod. An end of the first movable rod is hinged to a support arm, and the support arm is hinged to the rotating shaft.

[0018] By adopting the above technical solution, when the rotating shaft axially moves relative to the rotating frame, during this process, the support arm pushes the first movable rod to flip. Under the linkage action of the first movable rod and the second movable rod, the top push rod is driven to axially move along the winding frame, thereby applying a thrust to the metal strip coil on the winding frame and further improving the blanking effect of the metal strip coil.

[0019] Optionally, the rotation axis of the rotating frame is vertically arranged, and a receiving seat for receiving the strip is arranged below the rotating frame on the frame. A guiding frame for guiding the strip is arranged on the receiving seat.

[0020] By adopting the above technical solution, the rotation axis of the rotating frame is vertically arranged, and a receiving seat and a guiding frame are arranged below the frame. When the stop rod flips to release the limiting effect on the metal strip coil, the metal strip coil can fall onto the receiving seat along the guiding frame under the action of gravity for blanking.

[0021] Optionally, a receiving groove for accommodating the receiving seat is arranged at the bottom of the frame. A flipping seat is rotatably connected to the frame. A driving unit for controlling the movement of the flipping seat is arranged on the frame. An installation groove for installing the receiving seat is arranged on the flipping seat. The rotation of the flipping seat can drive the receiving groove to align with the installation groove, so that the groove wall of the receiving groove blocks the notch of the installation groove to limit the receiving seat from detaching from the installation groove.

[0022] By adopting the above technical solution, a receiving groove and a flipping seat are provided at the bottom of the rack. By controlling the movement of the flipping seat through the driving unit, the rapid loading and unloading and replacement of the material receiving seat are realized. This structure makes the material receiving process more efficient and convenient.

[0023] Optionally, the driving unit includes a second electric push rod hinged to the rack, and the piston rod of the second electric push rod is hinged to the flipping seat.

[0024] By adopting the above technical solution, the cooperation of the second electric push rod and the flipping seat in the driving unit realizes the stable movement of the flipping seat.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The baffle and the stop rod are located on both sides of the winding rack, limiting the metal strip coil on the rotating rack. When blanking is required, the operator controls the flipping of the stop rod to release the limiting effect on the metal strip coil, and then controls the contraction of the winding rack to release the supporting effect on the inner circle of the metal strip coil, facilitating the blanking of the metal strip coil, which is beneficial to improving the processing efficiency of the metal strip coil and can reduce the wear during the blanking of the metal strip coil;

[0027] 2. Driven by the first electric push rod, the rotating shaft axially moves relative to the rotating rack. During this process, the support rod pushes the support arm to flip, and then drives the top push rod to axially move along the winding rack, thereby applying a thrust to the metal strip coil on the winding rack and further improving the blanking effect of the metal strip coil;

[0028] 3. The rotation axis of the rotating rack is vertically arranged, and a material receiving seat and a guiding frame are provided below the rack.

Detailed implementation manners

[0039] The following further describes the present application in detail Figure 1-8 with reference to the accompanying drawings.

[0040] The embodiment of the present application discloses a metal strip coiling device for cold-drawn bar production. As Figure 1 and Figure 2, The wire rod coiling device for cold-drawn bar production includes a frame 1 as a support structure. The frame 1 is welded from high-strength steel and has sufficient rigidity and stability to ensure the smooth operation of the entire device. The frame 1 is provided with a cantilever 11, and the cantilever 11 is fixedly connected to the frame 1 by welding or bolt connection. The cantilever 11 extends horizontally. A rotating frame 12 is rotatably connected below the cantilever 11. The rotating frame 12 is rotatably connected to the cantilever 11 through a bearing structure. A driving component 2 for controlling the rotation of the rotating frame 12 is provided on the rotating frame 12. The driving component 2 drives the rotating frame 12 to rotate so that the wire rod can be evenly wound on the winding frame 14. In the embodiment of the present application, the rotation axis of the rotating frame 12 is vertically arranged, and the rotating frame 12 is located below the cantilever 11.

[0041] As Figure 2 and Figure 3 , a ring of support plates 13 is movably arranged on the rotating frame 12 around the rotation axis. A plurality of support plates 13 enclose a winding frame 14 for winding the wire rod. A first control component 3 for controlling the mutual approach or separation of the plurality of support plates 13 is provided on the cantilever 11. In the unfolded state of the winding frame 14, the operator controls the rotation of the rotating frame 12 to drive the winding frame 14 to rotate and wind the metal wire rod. In this state, the support plates 13 support the inner ring of the metal wire rod coil; in the contracted state of the winding frame 14, the support effect on the metal wire rod coil is released.

[0042] As Figure 1 and Figure 4 , a baffle 16 is fixedly connected to one end of the rotating frame 12 close to the cantilever 11. A stop rod 17 is provided on the support plate 13 away from the cantilever 11. The baffle 16 and the stop rod 17 cooperate to limit the metal wire rod coil on the winding frame 14.

[0043] As Figure 2 and Figure 4 , wherein the stop rod 17 is hinged to the rotating frame 12. A second control component 4 for controlling the flipping of each stop rod 17 is provided on the rotating frame 12. When the stop rod 17 flips to the unfolded state for limiting the metal wire rod coil on the winding frame 14, when the stop rod 17 flips to the contracted state, the limiting effect is released, which is convenient for the operator to disassemble the metal wire rod coil from the winding frame 14.

[0044] As Figure 1 , the driving component 2 includes a first sprocket 21 fixedly connected to the rotating frame 12. A second sprocket 22 is rotatably connected to the cantilever 11. The first sprocket 21 and the second sprocket 22 are connected by a chain 23. A motor 24 is fixedly installed on the frame 1. The output shaft of the motor 24 is connected to the second sprocket 22 through a coupling or a gear transmission mechanism. When the motor 24 works, it drives the second sprocket 22 to rotate, and then drives the first sprocket 21 and the rotating frame 12 to rotate synchronously through the chain 23, realizing the automatic coiling of the wire rod.

[0045] As Figure 1 and Figure 2 , the first control component 3 includes a rotating shaft 31 that axially penetrates the rotating frame 12. The rotating shaft 31 and the rotating frame 12 share the same central axis, and the rotating shaft 31 is axially slidably arranged on the rotating frame 12, restricting the relative rotation between the rotating shaft 31 and the rotating frame 12. A control unit 35 for controlling the axial movement of the rotating shaft 31 relative to the rotating frame 12 is provided on the frame 1.

[0046] As Figure 5 and Figure 6 , each support plate 13 is provided with a first connecting rod 32 and a second connecting rod 33. One end of the first connecting rod 32 is hinged to the support plate 13, and the other end of the first connecting rod 32 is hinged to the rotating shaft 31. One end of the second connecting rod 33 is hinged to the rotating frame 12, and a sliding seat 34 is hinged to the other end of the second connecting rod 33. The sliding seat 34 is slidably arranged on the support plate 13. The middle parts of the first connecting rod 32 and the second connecting rod 33 are hinged to each other to form a linkage mechanism.

[0047] During the movement of the rotating shaft 31 relative to the rotating seat, it can control multiple support plates 13 to approach or move away from each other through the linkage of the first connecting rod 32 and the second connecting rod 33, thereby adjusting the diameter of the winding frame 14.

[0048] As Figure 1 and Figure 7 , the control unit 35 includes a first electric push rod 36 fixedly connected to the support arm 53. A rotating seat is fixedly connected to the piston rod of the first electric push rod 36, and the rotating seat is rotatably connected to the rotating shaft 31.

[0049] As Figure 5 and Figure 6 , the second control component 4 includes a crank 41 fixedly connected to the stop rod 17. The stop rod 17 is hinged to the rotating frame 12. A linkage rod 42 is hinged to the crank 41, and the other end of the linkage rod 42 is hinged to the rotating shaft 31. When the rotating shaft 31 axially moves, it drives the crank 41 to swing through the linkage rod 42, causing the stop rod 17 to flip around the hinge point to realize the limiting or releasing of the strip.

[0050] As Figure 2 and Figure 6, a push rod 5 is movably arranged at one end of the rotating frame 12 close to the cantilever 11. A first movable rod 51 and a second movable rod 52 which are parallel to each other are hinged on the push rod 5. The middle position of the first movable rod 51 is hinged to the rotating frame 12 through a first rotating shaft, and one end of the first movable rod 51 is hinged to the push rod 5 through a second rotating shaft. One end of the second movable rod 52 is hinged to the rotating frame 12 through a third rotating shaft, and the other end of the second movable rod 52 is hinged to the push rod 5 through a fourth rotating shaft. The axial distance between the first rotating shaft and the second rotating shaft is the same as the axial distance between the third rotating shaft and the fourth rotating shaft, so that when the first movable rod 51 flips, it drives the push rod 5 to move axially along the rotating shaft 31.

[0051] A support arm 53 is hinged to the end of the first movable rod 51 away from the push rod 5, and the end of the support arm 53 away from the first movable rod 51 is hinged to the rotating shaft 31. When the rotating shaft 31 moves, it drives the support arm 53 to push the first movable rod 51 to flip. Under the linkage action of the first movable rod 51 and the second movable rod 52, the push rod 5 moves axially along the rotating shaft 31. The movement of the push rod 5 is used to push the metal strip coil away from the rotating frame 12, reducing the situation that the metal strip coil is stuck on the rotating frame 12 or the winding frame 14, resulting in the abnormal feeding of the metal strip coil.

[0052] The rotation axis of the rotating frame 12 is vertically arranged, so that the strip can vertically fall during the winding process, facilitating the winding operation. A winding seat 6 is placed below the frame 1 for receiving the wound strip. An installation groove 65 is arranged at the bottom of the frame 1, and the size of the installation groove 65 is adapted to the size of the bottom of the winding seat 6. The installation groove 65 is used to accommodate the winding seat 6. A guide frame 61 is arranged at the upper end of the winding seat 6. The guide frame 61 includes a plurality of interconnected guide rods 62. The outer diameter of the upper end of the guide frame 61 is smaller than the outer diameter of the lower end of the guide frame 61, and its internal shape matches the shape of the wound metal strip coil. During the falling process of the strip coil, the guide frame 61 passes through the metal strip coil, so that the guide frame 61 is regularly received on the winding seat 6, ensuring the neatness and stability of the metal strip coil.

[0053] As Figure 7 and Figure 8 , a flipping seat 64 is rotatably connected to the bottom of the frame 1 through a bearing. A driving unit 66 for controlling the rotation of the flipping seat 64 is arranged at the bottom of the frame 1. An installation groove 65 is arranged on the flipping seat 64. The shape of the installation groove 65 matches the shape of the winding seat 6 and is used to install the winding seat 6.

[0054] The driving unit 66 includes a second electric push rod 67 hinged to the bottom of the frame 1, and the piston rod of the second electric push rod 67 is hinged to the flipping seat 64. When it is necessary to replace the material receiving seat 6, the second electric push rod 67 is started, and its piston rod expands and contracts to drive the flipping seat 64 to rotate. When the flipping seat 64 rotates to a proper position, the accommodating groove 63 is aligned with the mounting groove 65, and the groove wall of the accommodating groove 63 will block the notch of the mounting groove 65, thereby restricting the material receiving seat 6 from disengaging from the mounting groove 65. At this time, an operator can conveniently remove the wound material roll from the material receiving seat 6 and install a new material receiving seat 6.

[0055] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
