Metal bar machining device

Abstract

The invention relates to the technical field of bar machining, and discloses a metal bar machining device which comprises a supporting frame, a polygonal barrel, a first polished shaft, a first support, a first rotating shaft, a circular truncated cone, a transmission part, a first driving part and a second driving part. During use, the circular truncated cones which are circularly distributed on the two adjacent sides reversely rotate around the center lines of the polygonal cylinders. Therefore, the bar is straightened in the clockwise direction and the anticlockwise direction, the torque borne by the surface of the bar is in a balanced state, and the bar is prevented from rotating around the axis of the bar. Meanwhile, under the transmission of the transmission part, when each polygonal barrel rotates, the multiple first rotating shafts on the inner side of the polygonal barrel can rotate along with the polygonal barrel. And finally, the bars are driven to move along the axes of the circular truncated cones, so that the bars are automatically fed. Due to the fact that the bar can only move along the axis of the bar and cannot rotate around the axis of the bar in the straightening process, radial run-out of the end of the bar when the bar is long can be avoided, and safety in the discharging process is 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] At present, straightening of metal bars is a common metal processing technology, which is used to restore bent or deformed metal bars to a straight state. The related technology (Announcement No.: CN118162507B) discloses a metal bar material straightening processing machine, which can adjust the straightening direction of the upper straightening wheel and the lower straightening wheel by setting a steering adjustment component, so as to better straighten the metal bar. The related technology (Announcement No.: CN115532884B) discloses a straightening device for metal bars, which can drive the driven roller to move up and down when the rotating shaft rotates under the limit of the limit mechanism, so as to adapt to bars of different sizes.

[0003] In the process of implementing the technical solution of the present disclosure, it is found that there are at least the following problems in the related technology: The metal bar material straightening machine cannot drive the bar to move along its axial direction during the straightening process to automatically load the material. Although the straightening device of the metal bar can drive the bar to move along its axis, it will also drive the bar to rotate around its axis. Therefore, during the straightening process, the bar will rotate rapidly. When the bar size is long, the end of the bar is prone to continuous radial runout, thereby affecting the straightening effect. In addition, the rapidly rotating bar is prone to cause safety accidents when the material is unloaded too late.

[0027] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0028] Combined with Figures 1 to 11As shown in the figure, an embodiment of the present disclosure provides a metal bar processing device, which includes a support frame, a polygonal cylinder 3, a first optical axis 4, a first support 5, a first rotating shaft 6, a frustum 7, a transmission member, a first driving member, and a second driving member. The support frame includes a bottom plate 1 and a top plate 2 whose planes are parallel to each other. Along the height direction of the support frame, the bottom plate 1 is located below the top plate 2, and the bottom plate 1 and the top plate 2 are respectively used to support and install relevant components of the device. The polygonal cylinders 3 are evenly distributed between the opposite surfaces of the bottom plate 1 and the top plate 2 along the length direction of the support frame. The center lines of the multiple polygonal cylinders 3 coincide with each other, and the number of side walls of each polygonal cylinder 3 is an even number. The first optical axes 4 are respectively slidably inserted through the side walls of each polygonal cylinder 3 and are evenly distributed on each polygonal cylinder 3. The multiple first optical axes 4 on each polygonal cylinder 3 are evenly distributed in a circular shape around the center line of the polygonal cylinder 3. The first optical axes 4 on each side wall of each polygonal cylinder 3 are distributed in pairs, and the two paired first optical axes 4 are both used for guiding and supporting. The first supports 5 are respectively installed on the multiple paired first optical axes 4 and are respectively located inside the multiple polygonal cylinders 3. Under the guiding and supporting action of multiple groups of paired first optical axes 4, the multiple first supports 5 in each polygonal cylinder 3 can approach or disperse from each other. The first rotating shafts 6 are respectively rotatably installed on the multiple first supports 5, and the axes of the multiple first rotating shafts 6 are all perpendicular to the center lines of the multiple polygonal cylinders 3 and are respectively used to support and install the frustum 7. The frustums 7 are respectively installed at both ends of each first rotating shaft 6 and are respectively located inside the multiple first supports 5. The multiple frustums 7 in each polygonal cylinder 3 are evenly distributed in a circular shape around the center line of the polygonal cylinder 3 and are all used to abut against the bar. The transmission members are respectively installed between each polygonal cylinder 3 and the multiple first rotating shafts 6 inside it and are all connected to the bottom plate 1, and are used to transmit driving force so that when each polygonal cylinder 3 rotates, the multiple first rotating shafts 6 inside it will rotate accordingly. The first driving member is installed between the bottom plate 1 and the multiple polygonal cylinders 3 and is used to provide driving force to drive two adjacent polygonal cylinders 3 to rotate in opposite directions. The second driving member is installed between the top plate 2 and the multiple first supports 5 and is used to provide driving force to drive the multiple first supports 5 in each polygonal cylinder 3 to approach or disperse from each other.

[0029] The present disclosure provides a metal bar processing device. After inserting one end of the bar into two groups of circularly distributed truncated cones 7 on one side, the second driving member is controlled to work. Under the guiding and supporting action of multiple groups of paired first optical axes 4, multiple first supports 5 in each polygonal tube 3 are brought closer or dispersed, and finally multiple truncated cones 7 in each polygonal tube 3 are driven to move closer or dispersed, so that the positions of multiple truncated cones 7 in each polygonal tube 3 match the size of the bar. Then the first driving member is controlled to work, so that the two adjacent polygonal tubes 3 can be rotated in the opposite direction. Then the two adjacent groups of circularly distributed first rotating shafts 6 are driven to rotate in the opposite direction, and finally multiple truncated cones 7 on both sides of the adjacent polygonal tubes 3 can be driven to rotate in the opposite direction around the center line of multiple polygonal tubes 3. Thus, 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 transmission of the transmission member, when each polygonal tube 3 rotates, multiple first rotating shafts 6 inside it will rotate accordingly. Then, multiple truncated tables 7 are driven to rotate simultaneously, and finally the rods are driven to move along their axes, so as to automatically load the rods. When the other side of the rod is located at the two groups of circularly distributed truncated tables 7 on the other side, the first driving member is controlled to stop working and the second driving member is reset, and then the rods can be unloaded. Since the rods can only move along their axes and not rotate around their axes during the straightening process, the radial runout of the ends of the rods can be avoided when they are long, and the safety during unloading can be improved.

[0030] 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 a plurality of first supports 5.

[0031] In the disclosed embodiment, the plurality of second seat 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 .

[0032] Optionally, combined Figures 7 to 10As shown in the figure, the transmission components include 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 shaft 8 is respectively rotatably inserted through a plurality of first supports 5, and the axes of the plurality of spline shafts 8 are all perpendicular to the center line of the plurality of polygon cylinders 3. The intersection points of the axes of the plurality of spline shafts 8 on each polygon cylinder 3 coincide with its center line. The first spline sleeve 9 is respectively slidably sleeved on one end of the plurality of spline shafts 8 located outside the plurality of first supports 5, and is respectively rotatably inserted through the side walls of the plurality of polygon cylinders 3, and is all used for transmitting torque. While the plurality of spline shafts 8 can slide relative to the plurality of first spline sleeves 9, the plurality of first spline sleeves 9 can drive the plurality of spline shafts 8 to rotate. The first bevel gears 10 are respectively installed on the outer walls of the plurality of first spline sleeves 9, and are respectively located outside the plurality of polygon cylinders 3. The first support plates 11 are respectively sleeved on the plurality of polygon cylinders 3, and are all installed on the top surface of the bottom plate 1. Each first support plate 11 includes a first conical tooth on its side surface, and the plurality of first conical teeth are respectively meshed with the plurality of 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 plurality of spline shafts 8 located inside the plurality of first supports 5. Among them, each first rotating shaft 6 includes a second conical tooth on its side surface, and the second conical tooth of each first rotating shaft 6 is located between the two frustums 7 on it. The plurality of second conical teeth are respectively meshed with the plurality of second bevel gears 12, and are all used for transmitting the driving force and changing the direction of the force. The meshing directions of the plurality of second conical teeth and the plurality of second bevel gears 12 on the inner sides of two adjacent polygon cylinders 3 are opposite, so that the plurality of frustums 7 distributed in a circular shape can rotate in the same reverse direction, so as to continuously convey the bar stock.

[0033] In the embodiment of the present disclosure, the plurality of polygon cylinders 3 perform rotational motion. Through the meshing action between the plurality of first conical teeth and the plurality of first bevel gears 10, the plurality of first spline sleeves 9 can be driven to rotate, and then the plurality of spline shafts 8 can be driven to rotate. Then, through the meshing action between the plurality of second conical teeth and the plurality of second bevel gears 12, the plurality of first rotating shafts 6 can be driven to rotate. Further drive the plurality of frustums 7 to rotate, so as to continuously convey the bar stock. Only through mechanical transmission, the function that when each polygon cylinder 3 rotates, the plurality of first rotating shafts 6 inside it rotate accordingly can be realized, without a large number of power sources respectively driving each first rotating shaft 6 to rotate. The phenomenon that the power cord is wound as the plurality of polygon cylinders 3 rotate can be avoided, and the subsequent wiring difficulty is reduced. And, through the design of the plurality of spline shafts 8 and the plurality of first spline sleeves 9, torque can be transmitted while sliding. So that each group of the plurality of frustums 7 can still rotate around its axis when approaching or dispersing from each other, thus avoiding interference.

[0034] Optionally, in combination with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , the transmission member further includes a third pedestal bearing. The third pedestal bearings are respectively sleeved on each spline shaft 8 and are respectively mounted on a plurality of first supports 5.

[0035] In the embodiment of the present disclosure, the plurality of third pedestal bearings are used to reduce the friction force between the plurality of spline shafts 8 and the plurality of first supports 5 and improve the accuracy when the plurality of spline shafts 8 rotate relative to the plurality of first supports 5.

[0036] Optionally, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , the transmission member further includes a fourth pedestal bearing. The fourth pedestal bearings are respectively sleeved on the outer walls of each first spline sleeve and are respectively mounted on a plurality of polygonal cylinders 3.

[0037] In the embodiment of the present disclosure, the plurality of fourth pedestal bearings are used to reduce the friction force between the plurality of first spline sleeves 9 and the plurality of polygonal cylinders 3 and improve the accuracy when the plurality of first spline sleeves 9 rotate relative to the plurality of polygonal cylinders 3.

[0038] Optionally, as shown in Figures 1 to 6 Figures 1 to 6 ​​​​​​​​​​​​​​​​​​As shown in the figure, the first driving member includes a second support plate 13, a cylinder 14, a first synchronous pulley 15, a first bearing pedestal bearing 16, a second rotating shaft 17, a second synchronous pulley 18, and a toothed belt 19. The second support plates 13 are evenly installed on the top surface of the bottom plate 1 along the length direction of the support frame, and are respectively located on the sides of a plurality of polygonal cylinders 3, and are respectively used to support and install the rotatable cylinders 14. The cylinders 14 are respectively rotatably inserted through the plurality of second support plates 13, and are respectively connected to the end faces of the plurality of polygonal cylinders 3. The axes of the plurality of cylinders 14 respectively coincide with the center lines of the plurality of polygonal cylinders 3, and the plurality of polygonal cylinders 3 respectively rotate driven by the plurality of cylinders 14. The first synchronous pulleys 15 are respectively sleeved on the outer walls of the plurality of cylinders 14. The first bearing pedestal bearings 16 are installed on the bottom surface of the bottom plate 1, and are respectively located below each cylinder 14 along the height direction of the support frame, and are respectively used to support and install the rotatable second rotating shafts 17. The second rotating shafts 17 are respectively installed on each first bearing pedestal bearing 16 along the length direction of the support frame, and the axes of the plurality of second rotating shafts 17 coincide with each other. The plurality of second rotating shafts 17 can respectively rotate around their axes under the support of the plurality of first bearing pedestal bearings 16. The second synchronous pulleys 18 are respectively sleeved on the plurality of second rotating shafts 17, and are respectively opposite to the plurality of first synchronous pulleys 15. The toothed belts 19 are respectively sleeved between the opposite first synchronous pulleys 15 and second synchronous pulleys 18, and all pass through the bottom plate 1, and are all used to transmit driving force. Among them, two adjacent second rotating shafts 17 are controlled to rotate reversely to drive two adjacent polygonal cylinders 3 to rotate reversely.

[0039] In the embodiment of the present disclosure, under the drive of an external force, after two adjacent second rotating shafts 17 rotate reversely, the adjacent second synchronous pulleys 18 can be driven to rotate reversely. Through a plurality of belts, the adjacent first synchronous pulleys 15 can be driven to rotate reversely. Furthermore, the adjacent cylinders 14 are driven to rotate reversely, and finally the reverse rotation function of the adjacent polygonal cylinders 3 is realized. Moreover, by adopting the design that a plurality of transmission components such as the plurality of second rotating shafts 17 are located below the bottom plate 1, it is possible to prevent dust or other sundries on the surface of the bar from directly falling on the surfaces of the relevant transmission components, thereby ensuring the transmission effect.

[0040] Optionally, in combination with Figures 1 to 5 As shown in the figure, 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.

[0041] 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 improve the accuracy when the plurality of cylinders 14 rotate relative to the plurality of second support plates 13.

[0042] Optionally, in combination with Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the first driving member further 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 bottom plate 1 along the height direction of the support frame, and is respectively located between two adjacent second rotating shafts 17 for supporting and mounting the third bevel gear 21. The third bevel gears 21 are respectively mounted on a plurality of third rotating shafts 20. The fourth bevel gears 22 are respectively engaged with a plurality of third bevel gears 21, and are respectively mounted on opposite ends of two adjacent second rotating shafts 17 to jointly transmit the driving force and change the direction of the acting force. Among them, any one of the second rotating shafts 17 can be controlled to rotate to drive two adjacent polygon barrels 3 to rotate in opposite directions.

[0043] In the embodiment of the present disclosure, under the drive of an external force, after any one of the second rotating shafts 17 is controlled to rotate, with the support of a plurality of third rotating shafts 20 and the meshing action between a plurality of third bevel gears 21 and a plurality of fourth bevel gears 22, the remaining second rotating shafts 17 can rotate in opposite directions or in the same direction. The two adjacent second rotating shafts 17 rotate in opposite directions, and finally the reverse rotation function of the adjacent polygon barrels 3 is realized. Through the design of a plurality of third bevel gears 21 and a plurality of fourth bevel gears 22, while transmitting the driving force, the direction of the acting force can be continuously changed. Thus, the reverse rotation of the adjacent polygon barrels 3 is realized without separately driving each second rotating shaft 17 to rotate, avoiding complex electrical interlocks.

[0044] Optionally, in combination with Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the first driving member further includes a fifth bearing with a seat.

[0046] Optionally, in combination with Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the first driving member further includes a motor 23 and a coupling 24. The motor 23 is mounted on the bottom surface of the bottom plate 1 for providing a 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 for transmitting the driving force.

[0047] In the embodiments of the present disclosure, by controlling the operation of the motor 23 and through the coupling 24, the second rotating shaft 17 connected thereto can be driven to rotate. Finally, the reverse rotation of two adjacent polygonal cylinders 3 and the continuous rotation function of multiple groups of multiple cylinders 14 distributed in a circular shape can be realized. Therefore, by using a single power source, the required rotational motion function of the device can be achieved, greatly reducing the number of power sources and facilitating control.

[0048] Optionally, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 , 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 respectively sleeved on multiple polygonal cylinders 3, and the axes of the multiple hollow spline shafts 25 respectively coincide with the center lines of the multiple polygonal cylinders 3. Each hollow spline shaft 25 is used to support and install a rotatable second spline sleeve 28 and multiple second supports 26. The second supports 26 are respectively and evenly installed on the outer wall of each hollow spline shaft 25 and are respectively used to support and install a rotatable triangular block 27. One corner of the multiple triangular blocks 27 is respectively rotatably installed on the multiple second supports 26. The second spline sleeves 28 are respectively slidably sleeved on the outer walls of the multiple hollow spline shafts 25, rotate driven by the multiple hollow spline shafts 25, and can slide relative to the multiple hollow spline shafts 25. The third supports 29 are respectively and evenly installed on the outer wall of each second spline sleeve 28, and the multiple third supports 29 on the outside of each second spline sleeve 28 and the multiple triangular blocks 27 are relatively distributed. The first connecting rods 30 are respectively rotatably installed between the other corners of the relatively distributed third supports 29 and triangular blocks 27 and are all used to transmit driving force. The fourth supports 31 are respectively installed on the multiple first supports 5, and the multiple fourth supports 31 inside each polygonal cylinder 3 and the multiple triangular blocks 27 on its outside are relatively distributed. The second connecting rods 32 are respectively rotatably installed between the remaining corners of the relatively distributed fourth supports 31 and triangular blocks 27 and are all used to transmit driving force. The connecting plates 33 are respectively and evenly connected between the outer walls of the multiple polygonal cylinders 3 and the inner walls of the multiple hollow spline shafts 25, and are used to determine the relative positions of the multiple polygonal cylinders 3 and the multiple hollow spline shafts 25 and to make the multiple hollow spline shafts 25 rotate as the multiple polygonal cylinders 3 rotate. Among them, the multiple second spline sleeves 28 are controlled to slide relative to the multiple hollow spline shafts 25 respectively to drive the multiple supports in each polygonal cylinder 3 to approach or disperse from each other.

[0049] In the embodiments of the present disclosure, under the drive of an external force, after multiple second spline sleeves 28 slide relative to multiple hollow spline shafts 25 respectively, multiple third supports 29 can be driven to slide. Then, under the push or pull of multiple first connecting rods 30, multiple triangular blocks 27 can rotate relative to multiple second supports 26. Then, under the push or pull of multiple second connecting rods 32 and the guiding and supporting action of multiple first optical axes 4, multiple fourth supports 31 can drive multiple first supports 5 to approach or separate from each other, and finally drive multiple frustums 7 distributed in a circular pattern to approach or separate from each other. Moreover, since the transmission members extend in the circumferential direction of multiple polygonal cylinders 3 instead of in the central line direction of multiple polygonal cylinders 3, the lateral space occupation can be reduced. Thereby, the distance between two adjacent polygonal cylinders 3 can be reduced, and finally the lateral distance of multiple frustums 7 distributed in a circular pattern can be reduced, facilitating the straightening of shorter bars. Meanwhile, when the length dimension of the device is fixed, more groups of frustums 7 can be increased along the length direction.

[0050] Optionally, as shown in Figure 1 , Figure 5 , Figure 6 and Figure 11 , the second driving member further includes a third support plate 34, a fifth support 35, a second optical axis 36 and a hydraulic cylinder 37. The third support plate 34 is respectively sleeved on the outer walls of multiple second spline sleeves 28 rotatably, and while being able to rotate relative to multiple second spline sleeves 28, it drives multiple second spline sleeves 28 to slide. The fifth support 35 is installed on the bottom surface of the top plate 2 and is used to support and install the second optical axis 36 and the hydraulic cylinder 37. The second optical axis 36 is arranged along the length direction of the support frame and is slidably penetrated through the fifth support 35. Along the width direction of the support frame, it is located on both sides of the fifth support 35, and both second optical axes 36 are used for guiding and supporting. Both second optical axes 36 are respectively connected to multiple third support plates 34, and multiple third support plates 34 move under the drive of both second optical axes 36. The hydraulic cylinder 37 is installed on the fourth support 31 along the length direction of the support frame and is located between both second optical axes 36 along the width direction of the support frame, and is used to provide driving force. The moving end of the hydraulic cylinder 37 is connected to the adjacent third support plate 34.

[0051] In the embodiments of the present disclosure, by controlling the hydraulic cylinder 37 to work, the adjacent third support plate 34 can be driven to move. Then, under the drive of both optical axes, the remaining third support plates 34 can move accordingly. Then, multiple second spline sleeves 28 can slide relative to multiple hollow spline shafts 25, and finally drive multiple frustums 7 distributed in a circular pattern to approach or separate from each other. Therefore, by using a single power source, the function of multiple frustums 7 distributed in a circular pattern approaching or separating from each other can be realized, greatly reducing the number of power sources and facilitating control.

[0052] Optionally, as shown in Figures 1 to 5As shown, the second driving member further includes a second bearing. The second bearing is used to enable the multiple third support plates 34 and the multiple second spline sleeves 28 to rotate relative to each other, and enable the multiple second spline sleeves 28 to move under the drive of the multiple third support plates 34.

[0053] Optionally, in combination with Figure 1 、 Figure 5 and Figure 6 As shown, the support frame further includes a first support rod 38. The first support rods 38 are evenly installed between the opposite surfaces of the bottom plate 1 and the top plate 2.

[0054] In the embodiments of the present disclosure, the multiple first support rods 38 are used to determine the relative positions of the bottom plate 1 and the top plate 2, and thus determine the distance between the bottom plate 1 and the top plate 2.

[0055] Optionally, in combination with 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 bottom plate 1 and are all used to abut against the ground.

[0056] In the embodiments of the present disclosure, the multiple second support rods 39 are all used to abut against the ground, thereby supporting the entire device and enabling the relevant transmission components installed on the bottom plate 1 to be above the ground.
