Metal bar processing device

Abstract

The present application relates to the technical field of bar processing, and discloses a metal bar processing device, including a support frame, a polygonal cylinder, a first optical axis, a first support, a first rotating shaft, a truncated cone, a transmission member, a first driving member, and a second driving member. When in use, a plurality of truncated cones distributed in a circular pattern on adjacent sides rotate in opposite directions around the center lines of the plurality of polygonal cylinders. Thereby, the bar is straightened in both clockwise and counterclockwise directions, so that the torque on the surface of the bar is in a balanced state to prevent the bar from rotating around its axis. At the same time, under the drive of the transmission member, when each polygonal cylinder rotates, the plurality of first rotating shafts inside it will rotate accordingly. This in turn drives the plurality of truncated cones to rotate simultaneously, and ultimately drives the bar to move along its axis to automatically load the bar. Since the bar can only move along its axis and cannot rotate around its axis during the straightening process, radial runout of the end of the bar when it is long can be avoided, and safety during unloading can be improved.

Description

Technical Field

[0001] The present application relates to the technical field of bar processing, and in particular to a metal bar processing device. Background Art

[0002] Currently, metal bar straightening is a common metalworking technology used to restore bent or deformed metal bars to a straight state. Related technology (Announcement No.: CN118162507B) discloses a metal bar straightening machine. This machine, through the provision of a steering adjustment assembly, can adjust the straightening direction of the upper and lower straightening wheels, thereby effectively straightening the metal bars. Related technology (Announcement No.: CN115532884B) discloses a metal bar straightening device. Under the limit of a limit mechanism, this metal bar straightening device can drive the driven roller to move up and down when the rotating shaft rotates, thereby accommodating bars of different sizes.

[0003] In the process of implementing the technical solution of the present disclosure, it was found that there are at least the following problems in the related technology:

[0004] This metal bar straightening machine is unable to move the bar axially during the straightening process for automatic loading. While the metal bar straightening device can move the bar along its axis, it also causes it to rotate around its axis. Therefore, the bar rotates rapidly during the straightening process. When the bar is long, the end of the bar is prone to continuous radial runout, affecting the straightening effect. Furthermore, the rapidly rotating bar can easily cause safety accidents during unloading.

Under the guiding support of multiple sets of paired first optical axes, the multiple first supports within each polygonal tube move closer or farther apart, ultimately driving the multiple truncated cones within each polygonal tube to move closer or farther apart, so that the positions of the multiple truncated cones within each polygonal tube match the dimensions of the bar. The first drive member is then controlled to rotate the two adjacent polygonal tubes in opposite directions. This in turn drives the two adjacent sets of circularly arranged first rotating shafts in opposite directions, ultimately driving the multiple circularly arranged cones on both sides to rotate in opposite directions about the centerlines of the multiple polygonal tubes. This straightens the bar in both clockwise and counterclockwise directions, balancing the torque on the bar surface and preventing the bar from rotating about its axis. Simultaneously, driven by the drive member, the multiple first rotating shafts within each polygonal tube rotate accordingly. This in turn drives the multiple truncated cones to rotate simultaneously, ultimately moving the bar along its axis for automatic loading. When the other side of the bar is positioned between the two circularly arranged truncated cones on the other side, the first drive element is controlled to stop and the second drive element is reset, and unloading can begin. Because the bar can only move along its axis during the straightening process and cannot rotate around it, radial runout of the end of the long bar is avoided, and safety during unloading is improved.

[0041] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0042] Combine Figures 1 to 11As shown, an embodiment of the present disclosure provides a metal bar processing device, comprising a support frame, a polygonal tube 3, a first optical axis 4, a first support 5, a first rotating shaft 6, a truncated cone 7, a transmission member, a first driving member, and a second driving member. The support frame comprises a bottom plate 1 and a top plate 2, whose planes are parallel to each other. Along the height of the support frame, the bottom plate 1 is located below the top plate 2. The bottom plate 1 and the top plate 2 are respectively used to support the relevant components of the mounting device. The polygonal tubes 3 are evenly distributed along the length of the support frame between the opposing surfaces of the bottom plate 1 and the top plate 2. The centerlines of the multiple polygonal tubes 3 coincide with each other, and each polygonal tube 3 has an even number of sidewalls. The first optical axes 4 are slidably disposed through the sidewalls of each polygonal tube 3 and are evenly distributed throughout each polygonal tube 3. The multiple first optical axes 4 on each polygonal tube 3 are evenly distributed in a circular pattern around the centerline of the polygonal tube 3. The first optical axes 4 on each sidewall of each polygonal tube 3 are arranged in pairs, and the two first optical axes 4 in each pair serve as guides and supports. The first supports 5 are mounted on the paired first optical axes 4 and located inside the polygonal tubes 3. Guided by the paired first optical axes 4, the first supports 5 within each polygonal tube 3 can move closer or further apart. First rotating shafts 6 are rotatably mounted on the first supports 5, with their axes perpendicular to the centerlines of the tubes 3. These first rotating shafts 6 are used to support and mount a circular platform 7. The circular platforms 7 are mounted at both ends of each first rotating shaft 6 and located inside the first supports 5. The circular platforms 7 within each polygonal tube 3 are evenly distributed around the centerline of the tube 3 and are used to abut against the rod. Transmission members are mounted between each polygonal tube 3 and the first rotating shafts 6 within it. Each transmission member is connected to the base plate 1, transmitting driving force so that the first rotating shafts 6 within each polygonal tube 3 rotate accordingly. A first driving member is mounted between the base plate 1 and the tubes 3, providing driving force to drive two adjacent polygonal tubes 3 in opposite directions. The second driving member is installed between the top plate 2 and the plurality of first supports 5 for providing a driving force to drive the plurality of first supports 5 in each polygonal tube 3 to move closer to or apart from each other.

[0043] The disclosed embodiments provide a metal bar processing device. After inserting one end of the bar into two sets of circularly arranged truncated cones 7 on one side, the second drive member is controlled to operate. Under the guiding and supporting action of multiple sets of paired first optical axes 4, the multiple first supports 5 within each polygonal tube 3 move closer or farther apart, ultimately driving the multiple truncated cones 7 within each polygonal tube 3 to move closer or farther apart, so that the positions of the multiple truncated cones 7 within each polygonal tube 3 match the dimensions of the bar. The first drive member is then controlled to rotate the two adjacent polygonal tubes 3 in opposite directions. This in turn drives the two adjacent sets of circularly arranged first rotating shafts 6 in opposite directions, ultimately driving the multiple circularly arranged cones 7 on both sides to rotate in opposite directions about the centerline of the multiple polygonal tubes 3. This straightens the bar in both clockwise and counterclockwise directions, maintaining a balanced torque on the bar surface and preventing the bar from rotating about its axis. Simultaneously, driven by the drive member, the multiple first rotating shafts 6 within each polygonal tube 3 rotate accordingly. This in turn drives the simultaneous rotation of the multiple circular platforms 7, ultimately moving the bar along its axis for automatic loading. Once the other side of the bar is positioned between the two circularly arranged sets of circular platforms 7 on the other side, the first drive element is deactivated and the second drive element is reset, allowing unloading to proceed. Since the bar can only move along its axis during the straightening process, rather than rotating around it, radial runout of the end of a long bar is avoided, improving safety during unloading.

[0044] Optionally, combined Figure 1 、 Figure 2 、 Figure 7 and Figure 9 As shown, the second bearing with a seat is also included. The second bearing with a seat is respectively mounted on both ends of each first rotating shaft 6 and is respectively installed on multiple first supports 5.

[0045] In the disclosed embodiment, the plurality of second seated bearings are used to reduce the friction between the plurality of first rotating shafts 6 and the plurality of first supports 5 and to improve the precision of the plurality of first rotating shafts 6 when rotating relative to the plurality of first supports 5 .

[0046] Optionally, combined Figures 7 to 10As shown, the transmission member includes a spline shaft 8, a first spline sleeve 9, a first bevel gear 10, a first support plate 11 and a second bevel gear 12. The spline shafts 8 are rotatably installed in multiple first supports 5, and the axes of the multiple spline shafts 8 are perpendicular to the center lines of the multiple polygonal cylinders 3. The intersection points of the axes of the multiple spline shafts 8 on each polygonal cylinder 3 coincide with its center line. The first spline sleeves 9 are slidably mounted on one end of the multiple spline shafts 8 located outside the multiple first supports 5, and are rotatably installed on the side walls of the multiple polygonal cylinders 3, and are used to transmit torque. While the multiple spline shafts 8 can slide relative to the multiple first spline sleeves 9, the multiple first spline sleeves 9 can drive the multiple spline shafts 8 to rotate. The first bevel gears 10 are respectively installed on the outer walls of the multiple first spline sleeves 9, and are respectively located outside the multiple polygonal cylinders 3. The first support plates 11 are respectively sleeved on the multiple polygonal cylinders 3 and are all installed on the top surface of the base plate 1. Each first support plate 11 includes a first conical tooth located on its side. The multiple first conical teeth are respectively engaged with the multiple first bevel gears 10 to jointly transmit the driving force and change the direction of the force. The second bevel gears 12 are respectively installed on one end of the multiple spline shafts 8 located on the inner side of the multiple first supports 5. Among them, each first rotating shaft 6 includes a second conical tooth located on its side. The second conical teeth of each first rotating shaft 6 are located between the two frustums 7 on it. The multiple second conical teeth are respectively engaged with the multiple second bevel gears 12 to transmit the driving force and change the direction of the force. The multiple second conical teeth on the inner side of two adjacent polygonal cylinders 3 are engaged with the multiple second bevel gears 12 in opposite directions, so that the multiple groups of multiple frustums 7 distributed in a circular shape can rotate in the same reverse direction, thereby continuously conveying the rods.

[0047] In the embodiment disclosed herein, when the multiple polygonal cylinders 3 rotate, the meshing action between the multiple first conical teeth and the multiple first bevel gears 10 can drive the multiple first spline sleeves 9 to rotate, thereby driving the multiple spline shafts 8 to rotate. Then, the meshing action between the multiple second conical teeth and the multiple second bevel gears 12 can drive the multiple first rotating shafts 6 to rotate. This in turn drives the multiple frustums 7 to rotate, thereby continuously conveying the bar material. Only through mechanical transmission can the function of rotating the multiple first rotating shafts 6 inside each polygonal cylinder 3 be achieved, without the need for a large number of power sources to drive each first rotating shaft 6 to rotate separately. This can avoid the phenomenon of power lines getting tangled as the multiple polygonal cylinders 3 rotate, reducing the difficulty of subsequent wiring. In addition, through the design of the multiple spline shafts 8 and the multiple first spline sleeves 9, torque can be transmitted while sliding. This allows each group of multiple frustums 7 to still rotate around their axis when they are close to or dispersed, thereby avoiding interference.

[0048] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 4、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the transmission member further includes a third seat bearing, which is respectively sleeved on each spline shaft 8 and respectively installed on the plurality of first supports 5.

[0049] In the disclosed embodiment, the plurality of third seated bearings are used to reduce the friction between the plurality of spline shafts 8 and the plurality of first supports 5 and to improve the precision of the plurality of spline shafts 8 when rotating relative to the plurality of first supports 5 .

[0050] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the transmission member further includes a fourth bearing with a seat. The fourth bearing with a seat is respectively sleeved on the outer wall of each first inter-flowered sleeve and is respectively installed on the multiple polygonal cylinders 3.

[0051] In the disclosed embodiment, the plurality of fourth seated bearings are used to reduce the friction between the plurality of first spline sleeves 9 and the plurality of polygonal cylinders 3 and to improve the precision of the plurality of first spline sleeves 9 when rotating relative to the plurality of polygonal cylinders 3 .

[0052] Optionally, combined Figures 1 to 6As shown, the first drive member includes a second support plate 13, a cylinder 14, a first synchronous pulley 15, a first bearing block 16, a second rotating shaft 17, a second synchronous pulley 18, and a toothed belt 19. The second support plates 13 are evenly mounted on the top surface of the base plate 1 along the length of the support frame and are located lateral to the multiple polygonal cylinders 3, respectively, for supporting and mounting the rotatable cylinders 14. The cylinders 14 are rotatably mounted through the multiple second support plates 13 and connected to the end surfaces of the multiple polygonal cylinders 3. The axes of the multiple cylinders 14 coincide with the centerlines of the multiple polygonal cylinders 3, and the multiple polygonal cylinders 3 rotate under the drive of the multiple cylinders 14. The first synchronous pulley 15 is mounted on the outer walls of the multiple cylinders 14. The first bearing block 16 is mounted on the bottom surface of the base plate 1 and located below each cylinder 14 along the height of the support frame, respectively, for supporting and mounting the rotatable second rotating shaft 17. The second rotating shaft 17 is installed on each first belt seat bearing 16 along the length direction of the support frame, and the axes of the multiple second rotating shafts 17 coincide with each other. Supported by the multiple first belt seat bearings 16, the multiple second rotating shafts 17 can rotate around their axes respectively. The second synchronous pulleys 18 are respectively mounted on the multiple second rotating shafts 17 and are respectively opposite to the multiple first synchronous pulleys 15. The toothed belts 19 are respectively mounted between the opposite first synchronous pulleys 15 and second synchronous pulleys 18, and both pass through the base plate 1 and are used to transmit driving force. Among them, the two adjacent second rotating shafts 17 can be controlled to rotate in opposite directions to drive the two adjacent polygonal cylinders 3 to rotate in opposite directions.

[0053] In the disclosed embodiment, driven by an external force, two adjacent second rotating shafts 17 rotate in opposite directions, thereby driving the adjacent second synchronous pulleys 18 to rotate in opposite directions. Multiple belts can then drive the adjacent first synchronous pulleys 15 to rotate in opposite directions. This in turn drives the adjacent cylinders 14 in opposite directions, ultimately achieving the opposite rotation function of the adjacent polygonal cylinders 3. Furthermore, the design of multiple second rotating shafts 17 and other transmission components located below the base plate 1 prevents dust or other debris from the rod material from directly falling onto the surfaces of the relevant transmission components, thereby ensuring effective transmission.

[0054] Optionally, combined Figures 1 to 5 As shown, the first driving member further includes a first bearing. The first bearings are respectively installed between the plurality of second support plates 13 and the plurality of cylinders 14.

[0055] In the embodiment of the present disclosure, the plurality of first bearings are used to reduce the friction between the plurality of cylinders 14 and the plurality of second support plates 13 and to improve the precision of the plurality of cylinders 14 when rotating relative to the plurality of second support plates 13 .

[0056] Optionally, combined Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the first driving member also includes a third rotating shaft 20, a third bevel gear 21 and a fourth bevel gear 22. The third rotating shaft 20 is rotatably mounted on the bottom surface of the base plate 1 along the height direction of the support frame, and is respectively located between two adjacent second rotating shafts 17, and is respectively used to support and install the third bevel gear 21. The third bevel gears 21 are respectively mounted on multiple third rotating shafts 20. The fourth bevel gear 22 is respectively engaged with the multiple third bevel gears 21, and is respectively mounted on the opposite ends of two adjacent second rotating shafts 17, jointly transmitting the driving force and changing the direction of the force. Among them, any second rotating shaft 17 can be controlled to rotate to drive the two adjacent polygonal cylinders 3 to rotate in opposite directions.

[0057] In the disclosed embodiment, driven by an external force, after any second rotating shaft 17 is controlled to rotate, the remaining second rotating shafts 17 can rotate in the opposite direction or in the same direction, supported by the multiple third rotating shafts 20 and the meshing action between the multiple third bevel gears 21 and the multiple fourth bevel gears 22. This causes two adjacent second rotating shafts 17 to rotate in opposite directions, ultimately achieving the function of reverse rotation of adjacent polygonal cylinders 3. Through the design of multiple third bevel gears 21 and multiple fourth bevel gears 22, the direction of force can be continuously changed while transmitting the driving force. This allows the reverse rotation of adjacent polygonal cylinders 3 to be achieved without having to drive each second rotating shaft 17 to rotate separately, avoiding complex electrical interlocking.

[0058] Optionally, combined Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the first driving member further includes a fifth bearing seat. The fifth bearing seats are respectively mounted on the plurality of third rotating shafts 20 and are all installed on the ground of the base plate 1.

[0059] In the disclosed embodiment, the plurality of fifth seated bearings are used to reduce the friction between the plurality of third rotating shafts 20 and the base plate 1 and to improve the precision of the plurality of third rotating shafts 20 when rotating relative to the base plate 1 .

[0060] Optionally, combined Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the first driving member also includes a motor 23 and a coupling 24. The motor 23 is mounted on the bottom surface of the base plate 1 to provide driving force. The coupling 24 is mounted between the rotating end of the motor 23 and one of the two outermost second rotating shafts 17 to transmit the driving force.

[0061] In the disclosed embodiment, the motor 23 is controlled to rotate, via the coupling 24, the second rotating shaft 17 connected thereto. This ultimately achieves the counter-rotation of two adjacent polygonal cylinders 3, as well as the continuous rotation of multiple groups of circularly distributed cylinders 14. Thus, a single power source can achieve the required rotational motion of the device, significantly reducing the number of power sources and facilitating control.

[0062] Optionally, combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 9 As shown, the second driving member includes a hollow spline shaft 25, a second support 26, a triangular block 27, a second spline sleeve 28, a third support 29, a first connecting rod 30, a fourth support 31, a second connecting rod 32, and a connecting plate 33. The hollow spline shafts 25 are sleeved onto the multiple polygonal cylinders 3, with the axes of the multiple hollow spline shafts 25 coinciding with the centerlines of the multiple polygonal cylinders 3. Each hollow spline shaft 25 is used to support and mount a rotatable second spline sleeve 28 and multiple second supports 26. The second supports 26 are evenly mounted on the outer wall of each hollow spline shaft 25 and are respectively used to support and mount a rotatable triangular block 27. A corner of each triangular block 27 is rotatably mounted on the multiple second supports 26. The second spline sleeves 28 are slidably mounted onto the outer walls of the multiple hollow spline shafts 25, rotating under the drive of the multiple hollow spline shafts 25 and sliding relative to the multiple hollow spline shafts 25. The third supports 29 are evenly mounted on the outer wall of each second spline sleeve 28. The third supports 29 and the triangular blocks 27 on the outer side of each second spline sleeve 28 are relatively distributed. The first connecting rods 30 are rotatably mounted between the third supports 29 and the other corner of the triangular blocks 27, each for transmitting driving force. The fourth supports 31 are mounted on the first supports 5. The fourth supports 31 on the inner side of each polygonal cylinder 3 are relatively distributed and the triangular blocks 27 on the outer side are relatively distributed. The second connecting rods 32 are rotatably mounted between the fourth supports 31 and the other corner of the triangular blocks 27, each for transmitting driving force. The connecting plates 33 are evenly connected between the outer walls of the polygonal cylinders 3 and the inner walls of the hollow spline shafts 25, respectively, for determining the relative positions of the polygonal cylinders 3 and the hollow spline shafts 25 and allowing the hollow spline shafts 25 to rotate with the rotation of the polygonal cylinders 3. The plurality of second spline sleeves 28 are controlled to slide relative to the plurality of hollow spline shafts 25 , respectively, so as to drive the plurality of supports in each polygonal tube 3 to move closer to or disperse from each other.

[0063] In the disclosed embodiment, driven by an external force, the multiple second spline sleeves 28 slide relative to the multiple hollow spline shafts 25, thereby driving the multiple third supports 29 to slide. Subsequently, driven or pulled by the multiple first connecting rods 30, the multiple triangular blocks 27 rotate relative to the multiple second supports 26. Subsequently, driven or pulled by the multiple second connecting rods 32, and guided and supported by the multiple first optical axes 4, the multiple fourth supports 31 drive the multiple first supports 5 to move toward or away from each other, ultimately driving the multiple circularly distributed truncated cones 7 to move toward or away from each other. Furthermore, because the transmission member extends circumferentially around the multiple polygonal cylinders 3 rather than toward their centerlines, lateral space usage is reduced. This reduces the distance between adjacent polygonal cylinders 3, ultimately reducing the lateral distance between the multiple circularly distributed truncated cones 7, facilitating the straightening of shorter bars. Furthermore, while the device's length is fixed, additional groups of truncated cones 7 can be added along the length.

[0064] Optionally, combined Figure 1 、 Figure 5 、 Figure 6 and Figure 11 As shown, the second driving member also includes a third support plate 34, a fifth support 35, a second optical axis 36, and a hydraulic cylinder 37. The third support plates 34 are rotatably mounted on the outer walls of the plurality of second splined sleeves 28, allowing them to rotate relative to the plurality of second splined sleeves 28 while simultaneously driving the plurality of second splined sleeves 28 to slide. The fifth support 35 is mounted on the bottom surface of the top plate 2 and supports the second optical axis 36, or hydraulic cylinder 37. The second optical axis 36 slidably extends through the fifth support 35 along the length of the support frame and is located on either side of the fifth support 35 along the width of the support frame. The second optical axis 36 on either side serves as a guide. The second optical axis 36 on either side is connected to the plurality of third support plates 34, and the plurality of third support plates 34 move under the drive of the second optical axis 36 on either side. The hydraulic cylinder 37 is mounted on the fourth support 31 along the length of the support frame and is located between the second optical axis 36 along the width of the support frame to provide driving force. The movable end of the hydraulic cylinder 37 is connected to the adjacent third support plate 34 .

[0065] In the disclosed embodiment, controlling the hydraulic cylinder 37 to operate moves the adjacent third support plate 34. Driven by the optical axes on both sides, the remaining third support plates 34 can then move accordingly. The multiple second spline sleeves 28 can then slide relative to the multiple hollow spline shafts 25, ultimately driving the multiple circularly distributed truncated platforms 7 to move toward or away from each other. Thus, a single power source can be used to achieve the function of moving the multiple circularly distributed truncated platforms 7 toward or away from each other, significantly reducing the number of power sources and facilitating control.

[0066] Optionally, combined Figures 1 to 5As shown, the second driving member further includes a second bearing. The second bearing is used to enable the third support plates 34 and the second spline sleeves 28 to rotate relative to each other, and to enable the second spline sleeves 28 to move under the drive of the third support plates 34.

[0067] Optionally, combined Figure 1 、 Figure 5 and Figure 6 As shown, the support frame further includes a first support rod 38. The first support rod 38 is evenly installed between the opposite surfaces of the bottom plate 1 and the top plate 2.

[0068] In the embodiment of the present disclosure, the plurality of first support rods 38 are used to determine the relative position of the bottom plate 1 and the top plate 2 , and further determine the distance between the bottom plate 1 and the top plate 2 .

[0069] Optionally, combined Figure 1 、 Figure 5 and Figure 6 As shown, the support frame further includes a second support rod 39. The second support rods 39 are evenly installed on the bottom surface of the base plate 1 and are used to resist the ground.

[0070] In the embodiment of the present disclosure, the plurality of second support rods 39 are used to abut against the ground, thereby supporting the entire device and allowing the relevant transmission components installed on the base plate 1 to be located above the ground.
