Description

Technical Field

[0001] The utility model relates to the technical field of steel production, and particularly relates to a cutting system for round bar production. Background Art

[0002] At present, a cold shear is usually used to cut round bars. Specifically, a conveying device is arranged on one side of the feeding end of the cold shear to convey the round bars, and a lifting roller and a pressing roller are installed on one side of the feeding end of the cold shear. The pressing roller is located above the lifting roller. The lifting roller is used to lift one end of the round bar close to the cold shear to lift one end of the round bar above the lower cutting knife, and the pressing roller is used to press the round bar downward so that the cutting knife assembly can stably cut the round bar. The cold shear internally has a cutting knife assembly, which includes an upper cutting knife and a lower cutting knife. The upper cutting knife is located above the lower cutting knife, and the upper cutting knife and the lower cutting knife are staggered. A plurality of first cutting knife grooves are provided on the upper edge of the lower cutting knife, and a plurality of second cutting knife grooves are provided on the lower edge of the upper cutting knife. The first cutting knife grooves and the second cutting knife grooves cooperate to cut the round bar.

[0003] When cutting the round bar, multiple round bars on the conveying device gradually approach the cold shear as the conveying device operates until one end of the round bar is conveyed close to the lower cutting knife. At this time, the end of the round bar extending into the cold shear exceeds the lifting roller. Then, the lifting roller lifts the end of the round bar extending into the cold shear so that the end of the round bar extending into the cold shear is higher than the lower cutting knife. Then, the conveying device continues to operate so that the end of the round bar extending into the cold shear exceeds the lower cutting knife. Then, the worker uses a long rod to push each round bar so that each round bar just enters each first cutting knife groove of the lower cutting knife. Finally, the pressing roller presses the round bar downward, and the upper cutting knife moves downward to cooperate with the lower cutting knife to cut a section of the round bar exceeding the lower cutting knife.

[0004] Since currently, it relies on manual use of a long rod to pick the round bar to place one end of the round bar into the first cutting knife groove of the lower cutting knife in the cold shear, and it is impossible to automatically place one end of the round bar into the first cutting knife groove of the lower cutting knife, resulting in low work efficiency. Moreover, due to the narrow space inside the cold shear, there are many safety hazards in manual feeding, high labor intensity, and it is easy to cause safety accidents such as mechanical injuries.

[0032] The conveyor roller on the top of the conveyor table conveys the round rod until the end of the round rod facing the cold shear machine is placed on the protrusion on the top of the workbench, and then the closing assembly closes the round rods so that multiple round rods are brought together toward the middle position of the conveyor table surface, and multiple round rods enter the predetermined position. At this time, each dividing head is located directly above the gap between the multiple round rods, and then the lifting roller moves upward to lift the right end of the round rod so that the right end of the round rod is higher than the lower cutting knife. Then the dividing device moves toward the table surface of the conveyor table to lower the height of the scissors frame mechanism, so that multiple dividing heads on the scissors frame mechanism are simultaneously inserted into the gap between the round rods, and then the two-way driving device drives the two ends of the scissors frame mechanism away from each other, and any two symmetrical first nodes on the scissors frame mechanism also move away from each other, thereby simultaneously driving the dividing heads on any two symmetrical first nodes to move away from each other, and finally multiple dividing heads move outward at the same time to push multiple round rods to move outward at the same time, so that the gap between any two adjacent round rods is adjusted to the set value, and at this time, multiple round rods just move to directly above the multiple first cutting grooves of the lower cutting knife. Then the dividing device moves toward the direction away from the conveyor table, so that the dividing head is pulled out from the gap between the two round bars, and then the lifting roller moves down, and the right end of each round bar enters into the first cutting groove on the cutter respectively, and finally the lower pressure roller mechanism presses down the round bar, and the upper cutter moves down to cooperate with the lower cutter to cut the round bar.

[0033] Therefore, there is no need to manually use a long rod to move the round bars to the first cutting groove of the lower cutting knife, which greatly improves work efficiency, reduces labor intensity, avoids safety accidents caused by manual material selection, and improves safety.

[0054] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0055] As Figures 1 - 17As shown in the figure, an embodiment of the present utility model provides a round bar production cutting system, including a cold shear 1, a closing assembly, and a material distribution device. The cold shear 1 includes a lower cutting knife and an upper cutting knife. A plurality of first cutting knife grooves are provided on the lower edge of the upper cutting knife, and a plurality of second cutting knife grooves corresponding to the first cutting knife grooves one by one are provided on the upper edge of the lower cutting knife. A set of first and second cutting knife grooves cooperate to cut a round bar;

[0056] The cold shear 1 includes a conveying table 101, which is arranged at the feeding end of the cold shear 1, and a conveying roller path for conveying round bars is provided on the conveying table 101;

[0057] The closing assembly is used to close the round bars towards the middle of the conveying table 101;

[0058] The material distribution device includes a scissors frame mechanism, a bidirectional driving device, and a plurality of material distribution heads. The material distribution device is arranged above the conveying table 101 and can be close to or away from the table surface of the conveying table 101. The scissors frame mechanism includes a plurality of scissors arms. The point where the middle of any one scissors arm is connected to the middle of an adjacent scissors arm forms a first node, and a material distribution head is installed at the bottom of each first node;

[0059] The bidirectional driving device is used to drive the two ends of the scissors frame mechanism to approach or move away from each other.

[0060] It should be noted that, as Figure 1 shown, a conveying table 101 is provided at the left feeding end of the cold shear 1. The right end of the conveying table 101 extends into the feeding end of the cold shear 1. A conveying roller path is provided on the top of the conveying table 101. The conveying roller path is composed of a plurality of conveying rollers, and the plurality of conveying rollers are arranged in sequence along the length direction of the conveying table 101 for conveying round bars. As Figure 2 and Figure 3 shown, the cold shear 1 has a workbench 102 inside. The workbench 102 is located at the left feeding end of the cold shear 1. The conveying table 101 is arranged on the left side of the workbench 102 and is close to the workbench 102. An integral raised platform is provided on the top of the right side of the conveying table 101. The raised platform is connected to the raised part on the top of the workbench 102, and the upper surface of the raised platform is flush with the upper surface of the raised part on the top of the workbench 102. It should be noted that a plurality of conveying rollers are provided on the conveying table 101 along its length direction. A groove adapted to the lifting roller is provided on the upper surface of the raised platform on the right side of the conveying table 101. The cutting knife assembly is located on the right side of the raised part on the top of the workbench 102, and the lower cutting knife is higher than the upper surface of the raised part on the top of the workbench 102. Further, a lower pressing roller mechanism 103 is installed at the left feeding end of the cold shear 1. It should be noted that the conveying table 101, the workbench 102, the lifting roller, and the lower pressing roller mechanism 103 all belong to the prior art, and the improvement points of this application do not lie in the conveying table 101, the workbench 102, the lifting roller, and the lower pressing roller mechanism 103.

[0061] In the past, the conveyor roller on the top of the conveyor platform 101 conveyed the round rod until the end of the round rod facing the cold shear machine 1 was placed on the top protrusion of the workbench 102, and then the lifting roller moved upward to lift the right end of the round rod, so that the right end of the round rod was higher than the lower cutter, and then the conveyor roller continued to move the round rod, so that the right end of the round rod exceeded the lower cutter, that is, the right end of the round rod moved to the right side of the lower cutter, and then the worker used a long rod to move the round rod, so that each round rod was adjusted to be directly above the first cutting groove on the lower cutter, and then the lifting roller moved down, and the right end of each round rod entered the first cutting groove on the cutter respectively, and finally the lower pressure roller mechanism 103 pressed down the round rod, and the upper cutter moved down to cooperate with the lower cutter to cut the round rod.

[0062] Different from this, in this embodiment, the conveyor roller on the top of the conveyor platform 101 conveys the round rods until the end of the round rods facing the cold shearing machine 1 is placed on the top protrusion of the workbench 102, and then the assembly is closed to bring the round rods together, so that the multiple round rods are brought together toward the middle position of the conveyor platform 101 table surface, and the multiple round rods enter the predetermined position. At this time, each material dividing head is located directly above the gap between the multiple round rods.

[0063] Then the lifting roller moves upward to lift the right end of the round rod so that the right end of the round rod is higher than the lower cutting knife. Then the dividing device moves toward the table surface of the conveying table 101 to lower the height of the scissors frame mechanism, so that the multiple dividing heads on the scissors frame mechanism are inserted into the gap between the round rods at the same time. Then the two-way driving device drives the two ends of the scissors frame mechanism away from each other, and any two symmetrical first nodes on the scissors frame mechanism also move away from each other, thereby driving the dividing heads on any two symmetrical first nodes away from each other at the same time. Finally, multiple dividing heads move outward at the same time to push multiple round rods to move outward at the same time, so that the gap between any two adjacent round rods is adjusted to the set value. At this time, multiple round rods just move to the top of the multiple first cutting grooves of the lower cutting knife. Then the material dividing device moves toward the direction of the table surface away from the conveying table 101, so that the material dividing head is pulled out from the gap between the two round rods, and then the lifting roller moves down, and the right end of each round rod enters into the first cutting groove on the cutter respectively, and finally the lower pressure roller mechanism 103 presses down the round rod, and the upper cutter moves down to cooperate with the lower cutter to cut the round rod.

[0064] It can be seen that in this embodiment, there is no need to manually use a long rod to move the round rods to move each round rod into the first cutting groove of the lower cutting knife. The work efficiency is greatly improved, the labor intensity is reduced, the safety accidents caused by manual material selection are avoided, and the safety is improved.

[0065] It should be noted that if Figure 12As shown, the scissors lift mechanism includes a plurality of X-shaped scissors forks, which are sequentially hinged to each other. The scissors fork includes a first scissors arm 726 and a second scissors arm 727. The middle parts of the first scissors arm 726 and the second scissors arm 727 in the scissors fork are hinged to each other. A first hinge plate 724 and a second hinge plate 725 are formed on the left side of the scissors lift mechanism. One end of the first hinge plate 724 is hinged to one end of the second hinge plate 725. The other end of the first hinge plate 724 is hinged to one end of the first scissors arm 726 in the adjacent scissors fork. The other end of the second hinge plate 725 is hinged to one end of the second scissors arm 727 in the adjacent scissors fork. On the right side of the scissors lift mechanism, there are a third hinge plate 728 and a fourth hinge plate 729. Among them, one end of the third hinge plate 728 is hinged to one end of the fourth hinge plate 729. The other end of the third hinge plate 728 is hinged to one end of the first scissors arm 726 in the adjacent scissors fork. The other end of the fourth hinge plate 729 is hinged to one end of the second scissors arm 727 in the adjacent scissors fork.

[0066] It should be particularly noted that the point where the middle parts of the first scissors arm 726 and the second scissors arm 727 in the scissors fork are hinged forms a first node. Taking Figure 12 the direction into the paper surface as the top view direction, a first included angle is respectively formed on the left and right sides of the first scissors arm 726 and the second scissors arm 727 in each scissors fork. A second included angle is respectively formed on the front and back sides of the first scissors arm 726 and the second scissors arm 727 in each scissors fork. Figure 12 In it, the first included angle is an obtuse angle and the second included angle is an acute angle.

[0067] In this embodiment, a material distributing head is installed at the bottom of each first node. After the plurality of material distributing heads on the scissors lift mechanism are simultaneously inserted into the gaps between the round bars, the two-way driving device drives the two ends of the scissors lift mechanism to move away from each other. The angle of the first included angle between the first scissors arm 726 and the second scissors arm 727 in any one scissors fork gradually decreases while the second included angle gradually increases, that is, the distance between two adjacent scissors forks gradually increases, so that any two symmetric first nodes on the scissors lift mechanism also move away from each other accordingly, thereby driving the material distributing heads on any two symmetric first nodes to move away from each other at the same time. Finally, the plurality of material distributing heads move outward simultaneously to push the plurality of round bars to move outward simultaneously, so that the gap between any two adjacent round bars is adjusted to a set value, thereby playing a role in uniformly pushing the round bars to both sides, enabling each round bar to just move into the first cutting groove of each lower cutting knife.

[0068] As a preferred embodiment, as Figure 2As shown in the figure, the cutting system for round bar production includes a support frame assembly, a moving frame 6, and a linear drive device 11. Among them, the support frame assembly includes two support frames 4, which are respectively fixedly installed on the stepped surfaces on the front and back of the conveying table 101, and the right end of the support frame 4 extends to the upper surface of the workbench 102 and is connected to the upper surface of the workbench 102. Both ends of the moving frame 6 are slidably connected to the two support frames 4, and the linear drive device 11 is used to drive the moving frame 6 to reciprocate along the conveying direction of the round bar on the support frame 4. Further, the material distribution device is installed on the moving frame 6 and moves together with the moving frame 6.

[0069] Preferably, as Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 shown in the figure, the material distribution device includes a main shaft 702, two side plates 701, two connecting plates 703, a bidirectional threaded rod 705, a drive device, a first threaded sleeve 718, a first moving sleeve, a fixed sleeve, and a second threaded sleeve 721.

[0070] Among them, as Figure 6 shown in the figure, the main shaft 702 is rotatably installed on the moving frame 6, and the main shaft 702 is arranged along the width direction of the conveying table 101, that is, the length direction of the main shaft 702 is perpendicular to the conveying direction of the conveying roller path. The same ends of the two side plates 701 are fixedly installed at both ends of the main shaft 702, and the two connecting plates 703 are respectively fixedly installed at the ends of the two side plates 701 away from the main shaft 702. The bidirectional threaded rod 705 is rotatably installed between the two connecting plates 703, and the drive device is installed on one side plate 701 and is used to drive the bidirectional threaded rod 705 to rotate around its own axis.

[0071] Further, as Figure 9As shown in the figure, the fixed sleeve is fixed along the axial position of the middle part of the bidirectional threaded rod 705 relative to the middle part of the bidirectional threaded rod 705. There is no thread provided in the middle part of the bidirectional threaded rod 705, and threads with opposite thread directions are provided at both ends thereof. The first threaded sleeve 718 and the second threaded sleeve 721 are respectively screwed onto both ends of the bidirectional threaded rod 705. A plurality of first moving sleeves are respectively arranged between the first threaded sleeve 718 and the fixed sleeve and between the second threaded sleeve 721 and the fixed sleeve. The first moving sleeves are slidably mounted on the bidirectional threaded rod 705. Along the axis of the bidirectional threaded rod 705, the left and right ends of the scissors mechanism are respectively hinged to the first threaded sleeve 718 and the second threaded sleeve 721, that is, the hinge joint of the first hinge plate 724 and the second hinge plate 725 in the scissors mechanism is connected to the top surface of the first threaded sleeve 718, and the hinge point of the third hinge plate 728 and the fourth hinge plate 729 in the scissors mechanism is connected to the top surface of the second threaded sleeve 721. A plurality of first nodes of the scissors mechanism are sequentially connected between the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve, the fixed sleeve, and the first moving sleeve between the fixed sleeve and the second threaded sleeve 721. A material distributing head is provided at the bottom of each of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721.

[0072] Furthermore, as Figure 10 shown in the figure, locking columns are screwed onto the tops of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721. A circular ring is coaxially provided at the top of the locking column. When installing the scissors mechanism onto the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721, first place the scissors mechanism on the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721, and align the circular hole at the connection of the first hinge plate 724 and the second hinge plate 725 with the threaded hole on the first threaded sleeve 718, align the plurality of first nodes on the scissors mechanism with the threaded holes on the first moving sleeve and the fixed sleeve at the same time, and align the circular hole at the connection of the third hinge plate 728 and the fourth hinge plate 729 with the threaded hole on the second threaded sleeve 721. Then, sequentially tighten the plurality of locking columns into the threaded holes on the first threaded sleeve 718, the threaded holes on the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve, the threaded holes on the fixed sleeve, the threaded holes on the first moving sleeve between the fixed sleeve and the second threaded sleeve 721, and the threaded holes on the second threaded sleeve 721.

[0073] When the driving device drives the bidirectional threaded rod 705 to rotate about its own axis, since the thread directions at both ends of the bidirectional threaded rod 705 are opposite, the first threaded sleeve 718 and the second threaded sleeve 721 are driven to move towards both sides simultaneously, causing the scissor mechanism to gradually unfold towards both sides. As the scissor mechanism gradually unfolds towards both sides, the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve drives the material dividing head on the first moving sleeve to move towards one side, and the first moving sleeve between the second threaded sleeve 721 and the fixed sleeve drives the material dividing head to move towards the other side, causing the gap between adjacent material dividing heads to gradually increase, thereby playing a role in adjusting the distance between adjacent round bars to move each round bar directly above the first cutting groove of the lower cutter.

[0074] Among them, it should be noted that a bearing is connected in cooperation with the middle part of the bidirectional threaded rod 705, and the fixed sleeve is coaxially arranged on the bearing. In this way, when the bidirectional threaded rod 705 rotates, the fixed sleeve will not rotate accordingly, so that the fixed sleeve can be fixed axially along the bidirectional threaded rod 705 relative to the middle part of the bidirectional threaded rod 705.

[0075] Furthermore, in this embodiment, as Figure 10 and Figure 11 shown, there are three first moving sleeves between the first threaded sleeve 718 and the fixed sleeve, and there are also three first moving sleeves respectively arranged between the second threaded sleeve 721 and the fixed sleeve. That is, there are a total of 7 first nodes.

[0076] In this embodiment, since the material dividing heads are only installed on the lower surfaces of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721, the actual number of round bars that can be toggled is small. In order to further enhance the efficiency of the material dividing device so as to simultaneously toggle more round bars onto the corresponding first cutting grooves of the lower cutter.

[0077] Preferably, as Figure 8 、 Figure 9 、 Figure 10 and Figure 11 , among any two adjacent scissor forks of the scissor mechanism, the point where the first end of the first scissor arm 726 of the first scissor fork is hinged to the first end of the second scissor arm 727 of the second scissor fork is the second node, and the point where the second end of the second scissor arm 727 in the first scissor fork is hinged to the second end of the first scissor arm 726 in the second scissor fork is the third node. That is, the second node and the third node are respectively located on both sides of the width direction of the scissor mechanism, and the first node is located between the second node and the third node. As Figure 8 shown, the second node is located on the right side of the third node, that is, the second node is closer to the cold shear machine 1.

[0078] Furthermore, as Figure 8As shown, the material distribution device further includes a first sliding rod 706, a second sliding rod 707, a plurality of second moving sleeves 719, and a plurality of third moving sleeves 720. Among them, a first limiting hole 714 and a second limiting hole 715 are respectively formed in each connecting plate 703. The length directions of the first limiting hole 714 and the second limiting hole 715 are perpendicular to the axis direction of the bidirectional threaded rod 705, that is, the length directions of the first limiting hole 714 and the second limiting hole 715 are consistent with the length direction of the conveying table 101. Both ends of the first sliding rod 706 are slidably installed between the first limiting holes 714 of the two connecting plates 703. Both ends of the second sliding rod 707 are respectively slidably installed between the second limiting holes 715 of the two connecting plates 703. The first sliding rod 706 is located on the right side of the bidirectional threaded rod 705, and the second sliding rod 707 is located on the left side of the bidirectional threaded rod 705. The axes of the first sliding rod 706, the second sliding rod 707, and the bidirectional threaded rod 705 are located in the same horizontal plane.

[0079] Further, a plurality of second moving sleeves 719 are slidably installed on the first sliding rod 706, and a plurality of third moving sleeves 720 are slidably installed on the second sliding rod 707. A material distribution head is installed at the bottom of each second moving sleeve 719. In order to distinguish this material distribution head from the material distribution head at the above-mentioned first node, this material distribution head is named the second material distribution head 717, and the material distribution heads at the bottoms of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721 are named the first material distribution head 716. Combining Figure 11 and Figure 12 , a plurality of second nodes are sequentially connected to the second moving sleeves 719, and a plurality of third nodes of the scissors mechanism are sequentially connected to the plurality of third moving sleeves 720. Further, the hinge point between the second hinge plate 725 and the adjacent scissor fork is connected to the second moving sleeve 719, the hinge point between the first hinge plate 724 and the adjacent scissor fork is connected to the third moving sleeve 720, the hinge point between the third hinge plate 728 and the adjacent scissor fork is connected to the second moving sleeve 719, and the hinge point between the fourth hinge plate 729 and the adjacent scissor fork is connected to the third moving sleeve 720.

[0080] When the bidirectional threaded rod 705 rotates, it will first drive the first threaded sleeve 718 and the second threaded sleeve 721 to move towards both sides respectively. Since the fixed sleeve is axially stationary relative to the bidirectional threaded rod 705, as the first threaded sleeve 718 and the second threaded sleeve 721 move towards both sides simultaneously, the scissor frame mechanism gradually unfolds towards both sides at the same time. The angle of the first included angle in each scissor fork gradually decreases, and the second included angle gradually increases, thereby pulling the first sliding rod 706 and the second sliding rod 707 closer to each other. As the scissor frame mechanism gradually unfolds towards both sides at the same time, the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve drives the first material distributing head 716 on the first moving sleeve to move towards the first side. At the same time, several second moving sleeves 719 on one side of the first sliding rod 706 drive the second material distributing head 717 to also move towards the first side. And the first moving sleeve between the second threaded sleeve 721 and the fixed sleeve drives the first material distributing head 716 to move towards the second side. Several second moving sleeves 719 on the other side of the first sliding rod 706 drive the second material distributing head 717 to move towards the second side. Finally, the gap between adjacent first material distributing heads 716 reaches the set value, and the gap between adjacent second material distributing heads 717 reaches the set value. In this way, the first material distributing head 716 and the second material distributing head 717 can simultaneously push each round bar towards the outside, so as to simultaneously deflect more round bars and improve production efficiency.

[0081] Optionally, a material distributing head is installed at the bottom of each third moving sleeve 720. At this time, no material distributing head is installed at the bottom of the second moving sleeve 719.

[0082] As a preferred embodiment, as Figure 3 、 Figure 5 and Figure 7 shown, the material distributing assembly 7 is installed on the moving frame 6. A carrying rail 12 is installed on the inner side of each of the two support frames 4. The carrying rail 12 is arranged along the conveying direction of the conveying roller path. The carrying rail 12 includes a straight rail and a bending part 1201 connected in sequence. The bending part 1201 is located at the right end of the straight rail, that is, the bending part 1201 is closer to the cold shear machine 1. The end of the bending part 1201 away from the straight rail is lower than the straight rail. A gap for the round bar to pass through is formed between the straight rail and the conveying roller path. The end of the bending part 1201 away from the straight rail is lower than the height of the round bar on the conveying table 101. Further, at least one walking wheel 712 is installed at the bottom of each of the two side plates 701. The walking wheels 712 on the two side plates 701 slide on the carrying rail 12 respectively.

[0083] When the round bar moves, the moving frame 6 is higher than the round bar at this time. The side plate 701 of the material distributing assembly 7 is placed on the straight rail of the bearing rail 12. Since the gap between the straight rail and the tabletop of the conveying table 101 is sufficient for the round bar to pass through, the material distributing assembly 7 is higher than the round bar. As the round bar moves on the conveying table 101 along with the conveying roller path on the conveying table 101 to the workbench 102, the lifting roller moves upward to lift the right ends of multiple round bars, making the right ends of multiple round bars higher than the lower cutting knife. Then the conveying roller path continues to drive the round bar to move to the right until the right end of the round bar exceeds the lower cutting knife. Then the closing assembly closes multiple round bars toward the middle position of the conveying table 101, making multiple round bars move to the set position. Subsequently, the moving frame 6 drives the material distributing assembly 7 to move to the right. The material distributing assembly 7 slides on the straight rail. When the material distributing assembly 7 moves to the bending part 1201, the main shaft 702 in the material distributing assembly 7 rotates naturally relative to the moving frame 6, thereby driving the side plate 701, the bidirectional threaded rod 705, the scissors frame mechanism, etc. to rotate. The scissors frame mechanism gradually approaches the round bar, so that multiple first material distributing heads 716 and multiple second material distributing heads 717 are simultaneously inserted into the gaps between the round bars. Subsequently, when the bidirectional threaded rod 705 rotates, it will drive the first threaded sleeve 718 and the second threaded sleeve 721 to move toward both sides respectively. Since the fixed sleeve is axially stationary relative to the bidirectional threaded rod 705, as the first threaded sleeve 718 and the second threaded sleeve 721 move toward both sides simultaneously respectively, the scissors frame mechanism gradually unfolds toward both sides at the same time. The angle of the first included angle in each pair of scissors forks gradually decreases, and the second included angle gradually increases, thereby pulling the first sliding rod 706 and the second sliding rod 707 to approach each other. As the scissors frame mechanism gradually unfolds toward both sides at the same time, finally the gap between adjacent first material distributing heads 716 reaches the set value, and the gap between adjacent second material distributing heads 717 reaches the set value, thereby pushing multiple round bars toward both sides simultaneously. Finally, the gap between adjacent two round bars reaches the set value. At this time, each round bar is respectively located directly above each first cutting knife groove of the lower cutting knife. Subsequently, the moving frame 6 moves to the left to drive the material distributing assembly 7 to withdraw from the bending part 1201 and move to the straight rail. Then the pressing roller presses down the round bar, and the upper cutting knife moves downward to cut short the round bar.

[0084] It can be seen that in this embodiment, the shearing work of the round bar can be completed automatically without manually using a long rod to stir the round bar to pick each round bar into the first cutting knife groove of the lower cutting knife respectively. The work efficiency is greatly improved, the labor intensity is reduced, the safety accidents caused by manual material feeding are avoided, and the safety is improved.

[0085] Preferably, as Figure 7 and Figure 8As shown, a bearing 713 is respectively installed on two connecting plates 703, and both ends of a bidirectional threaded rod 705 are respectively connected to the two bearings 713. The driving device includes a main gear 708, a transmission gear 709, a fixed gear 710 and a driving motor 711. Among them, the fixed gear 710 is fixedly installed at one end of the bidirectional threaded rod 705. A transmission gear 709 and a fixed gear 710 are successively rotatably installed on a side plate 701. The main gear 708, the transmission gear 709 and the fixed gear 710 are successively meshed with each other. The driving motor 711 is fixedly installed on the side plate 701, and the output end of the driving motor 711 is connected to the main gear 708 for driving the main gear 708 to rotate around its axis.

[0086] Optionally, in order to protect the scissors frame mechanism and the material distributing head, as Figure 6 , Figure 7 and Figure 8 shown, a protective cover 704 is installed between the two connecting plates 703.

[0087] Optionally, in order to further enhance the stability of the material distributing assembly 7 during material distribution, as Figure 10 and Figure 11 shown, there are two scissors frame mechanisms. Among them, the first scissors frame mechanism 722 is located above the first threaded sleeve 718, the first moving sleeve, the second moving sleeve 719, the third moving sleeve 720 and the second threaded sleeve 721, and the second scissors frame mechanism 723 is located below the first threaded sleeve 718, the first moving sleeve, the second moving sleeve 719, the third moving sleeve 720 and the second threaded sleeve 721.

[0088] Preferably, as Figure 11 shown, the material distributing head is integrally cylindrical, and its bottom is sharp, so as to be inserted into the gap between the round bars.

[0089] Preferably, as Figure 1 shown, a pedestal 2 is provided on the left side of the conveying table 101, and a roller conveyor is also installed on the pedestal 2. The closing assembly includes a first closing mechanism 3, a second closing mechanism 9 and a third closing mechanism 10. Among them, the first closing mechanism 3 is installed on the pedestal 2, the second closing mechanism 9 is installed at one end of the conveying table 101 close to the pedestal 2. A groove is opened on the tabletop of the conveying table 101, and the length direction of the groove is perpendicular to the length direction of the conveying table 101. The third closing mechanism 10 is installed in the groove. The first closing mechanism 3, the second closing mechanism 9 and the third closing mechanism 10 are respectively used to close the round bars from the tail end, the middle end and the head end of the round bars, so as to stably close the round bars towards the middle position of the conveying table 101.

[0090] Specifically, the first closing mechanism 3 and the second closing mechanism 9 have the same structure, both including two cylinders. The two cylinders of the first closing mechanism 3 are symmetrically arranged with respect to the pedestal 2 and are installed at the right end face of the pedestal 2. The two cylinders of the second closing mechanism 9 are symmetrically arranged with respect to the conveying table 101 and are installed at the left end face of the conveying table 101.

[0091] As Figure 17 shown, the third closing mechanism 10 includes a support base 1001, guide rails 1002, sliding seats 1003, vertical frames 1004, wheel bodies 1005, vertical seats 1006, two threaded rods 1007 and a second motor 1008. Among them, the support base 1001 is fixedly installed in the groove on the table top of the conveying table 101. A fixed platform is installed at the middle position of the support base 1001. Two guide rails 1002 are respectively fixedly installed on both sides of the top of the support base 1001. A sliding seat 1003 is slidably installed on each guide rail 1002. A vertical seat 1006 is respectively fixedly installed at both ends of the top of the support base 1001. A threaded rod 1007 is rotatably installed between the first vertical seat 1006 and the fixed platform, and a threaded rod 1007 is rotatably installed between the second vertical seat 1006 and the fixed platform. The thread directions of these two threaded rods 1007 are opposite, and these two threaded rods 1007 are connected by a coupling. A vertical frame 1004 is fixedly installed on the top of each sliding seat 1003. The output end of the second motor 1008 is fixedly connected to one end of a threaded rod 1007. Further, a wheel body 1005 is rotatably installed on each vertical frame 1004. Specifically, a wheel body 1005 is installed on the right side of the vertical frame 1004 on the left side of the support base 1001, and a wheel body 1005 is installed on the left side of the vertical frame 1004 on the right side of the support base 1001. Each wheel body 1005 is vertically arranged.

[0092] The second motor 1008 drives the two threaded rods 1007 to rotate simultaneously. Since the thread directions of these two threaded rods 1007 are opposite, the two sliding seats 1003 are driven to drive the two vertical frames 1004 to approach or move away from each other. When the two vertical frames 1004 approach each other, the wheel bodies 1005 on the two vertical frames 1004 respectively push the round rods on the conveying table 101 from the left and right sides of the conveying table 101 at the same time.

[0093] It should be noted that in the past, when cutting long round bars, due to the internal space limitation of the cold shear machine 1 and the fact that the conveying roller path on the conveying table 101 could not be arranged on the workbench 102 because lifting rollers needed to be arranged on the workbench 102, when the long round bar was cut multiple times and only the tail stock remained, the tail stock would fall on the protruding platform on the right side of the conveying table 101, and there was no contact between the tail stock and the conveying roller path. The conveying roller path could not continue to convey the tail stock. Therefore, workers had to use a long rod to reach into the cold shear machine 1 and push the tail stock so that the tail stock passed through the first cutting tool slot of the lower cutting blade and fell into the waste material guide slot of the cold shear machine 1, resulting in high labor intensity and low work efficiency for the workers.

[0094] To solve this problem, in this embodiment, the round bar production and cutting system includes a linear driving device 11 and a tail stock pushing device. The linear driving device 11 is used to drive the moving frame 6 to reciprocate along the conveying direction of the round bar on the support frame assembly.

[0095] The tail stock pushing device includes at least one tail stock pushing member. The tail stock pushing member is installed on the moving frame 6 and has a first state and a second state. When the tail stock pushing member is in the first state, there is a gap for the round bar to pass between the tail stock pushing member and the tabletop of the conveying table 101. When the tail stock pushing member is in the second state, the end of the tail stock pushing member close to the round bar tail stock is lower than the round bar tail stock.

[0096] When it is necessary to push the round bar tail stock into the waste material guide slot, the tail stock pushing member switches to the second state, and the linear driving device 11 drives the moving frame 6 to move towards the waste material guide slot direction, so that the tail stock pushing member pushes the round bar tail stock into the waste material guide slot of the cold shear machine 1.

[0097] In this way, when cutting the long round bar, the tail stock pushing member is in the first state. At this time, there is a gap for the round bar to pass between the tail stock pushing member and the tabletop of the conveying table 101. The long round bar passes through the gap between the tail stock pushing member and the tabletop of the conveying table 101 and enters the workbench 102 and rests on the workbench 102. When the long round bar is cut multiple times and only the tail stock remains, at this time the tail stock pushing member switches to the second state, and then the linear driving device 11 is started. The linear driving device 11 drives the moving frame 6 to move towards the waste material guide slot direction, so that the tail stock pushing member pushes the tail stock and makes the tail stock pass through the first cutting tool slot of the lower cutting tool and then fall into the waste material guide slot of the cold shear machine 1. Subsequently, the linear driving device 11 drives the moving frame 6 to move away from the cold shear machine 1 to drive the tail stock pushing member to withdraw from the cold shear machine 1 and return to the initial position, and the tail stock pushing member switches to the second state to wait for the next tail stock pushing work.

[0098] It can be seen that in this embodiment, there is no need for workers to use a long rod to push the tail stock into the waste material guide slot, and the automatic tail stock pushing work can be realized, which saves time and effort, reduces the labor burden of workers, and improves work efficiency.

[0099] As a preferred embodiment, as Figure 2 and Figure 3 shown, the support frame 4 includes a strip-shaped bearing seat and a plurality of support feet fixedly installed on the lower surface of the bearing seat. The support feet are fixedly installed on the conveying table 101 and the workbench 102. The strip-shaped bearing seat is used to support the moving frame 6.

[0100] Furthermore, a guide rail mechanism 5 is installed on each bearing seat. The guide rail mechanism 5 includes a guide rail 501 and a slider 502. The guide rail 501 is installed in the accommodation cavity of the bearing seat, and the guide rail 501 is arranged along the length direction of the bearing seat. A plurality of sliders 502 are slidably installed on each guide rail 501. Both sides of the bottom of the moving frame 6 are fixedly connected to the sliders 502 on the two guide rails 501 at the same time. In this way, pushing the moving frame 6 drives the slider 502 to slide on the guide rail 501, so as to realize the movement of the moving frame 6 along the length direction of the guide rail 501.

[0101] Furthermore, as Figure 4 shown, the linear drive device 11 includes two toothed plates 1105, two traveling gears 1104, two rotating shafts 1103, a gear box 1101 and a first motor 1102. The two toothed plates 1105 are respectively installed on the bearing seats of the two support frames 4, and the toothed plates 1105 are parallel to the guide rail 501. The gear box 1101 is fixedly installed on the side of the moving frame 6 away from the cold shearing machine 1. The top of the gear box 1101 has an input end, and its left and right sides respectively have output ends. The two output ends are coaxially arranged. For the convenience of distinction, the two rotating shafts 1103 are respectively named the first rotating shaft and the second rotating shaft. Among them, the first rotating shaft is connected to the output end on the left side of the gear box 1101, and a traveling gear 1104 is installed at the other end of the first rotating shaft. Correspondingly, one end of the second rotating shaft is connected to the output end on the right side of the gear box 1101, and a traveling gear 1104 is also installed at the other end of the second rotating shaft. The two traveling gears 1104 are respectively meshed with the toothed plates 1105 on the two bearing seats.

[0102] In this way, when the first motor 1102 is turned on, the first rotating shaft and the second rotating shaft are driven to rotate simultaneously through the transmission of the gear box 1101. The first rotating shaft and the second rotating shaft rotate simultaneously to drive the two traveling gears 1104 to rotate simultaneously, so that the traveling gears 1104 move along the length direction of the toothed plate 1105, so as to drive the moving frame 6 to move along the length direction of the toothed plate 1105, so that the moving frame 6 drives the tail stock pusher to extend into or withdraw from the cold shearing machine 1.

[0103] Preferably, as Figure 3 、 Figure 4 and Figure 13 shown, the tail stock pusher is installed on the side of the moving frame 6 facing the cold shearing machine 1, and is closer to the cold shearing machine 1 than the material distributing assembly 7. Specifically, asFigure 14 , the tail stock pusher includes a frame 801, a rotating frame 802 and a connecting shaft 803. The frame 801 includes two rod bodies and a fixing rod fixed between the two rod bodies. One ends of the two rod bodies close to the moving frame 6 are detachably connected to the moving frame 6. The other ends of the rod bodies are both provided with concave-shaped connecting seats. The connecting shaft 803 is rotatably installed between the two connecting seats of the two rod bodies. A compression spring 804 is arranged in each connecting seat. The compression spring 804 is sleeved on the connecting shaft 803 to limit the excessive rotation of the connecting shaft 803. The rotating frame 802 is fixedly connected to the connecting shaft 803. It should be noted that the frame 801 is parallel to the tabletop of the conveying table 101 and is higher than the top of the conveying table 101, so that a gap for the round bar to pass through is formed between the frame 801 and the conveying roller path at the top of the conveying table 101. It should be noted that in the natural state, due to the limitation of the compression spring 804, the rotating frame 802 is connected to the frame 801 in an inclined state, that is, in the natural state, the rotating frame 802 is not in a vertical state.

[0104] Further, as Figure 3 and Figure 4 shown, on both sides of the top of the conveying table 101, a deflector 14 used in cooperation with the tail stock pusher is respectively installed. The two deflectors 14 are symmetrically arranged with respect to the conveying table 101. The deflector 14 is arranged on the top of the conveying table 101. The deflector 14 has a bearing surface. When the tail stock pusher switches to the first state, the rotating frame 802 is placed on the bearing surface of the deflector 14.

[0105] Specifically, as Figure 16 shown, the deflector 14 includes an angle seat 1401 fixed to the side of the top of the conveying table 101 and a guide plate installed on the inner side wall of the angle seat 1401. Looking from the incoming material direction of the cold shearing machine 1, the angle seat 1401 is L-shaped, which includes a bottom plate and a vertical plate. The bottom plate is fixed to the top of the conveying table 101 by bolts, and the vertical plate is fixedly installed on the bottom plate and perpendicular to the bottom plate. The guide plate includes a connected inclined plate 1403 and a horizontal plate 1402. The horizontal plate 1402 is fixedly installed on the side of the vertical plate. One end of the inclined plate 1403 is connected to the surface of the horizontal plate 1402 facing the cold shearing machine 1. The other end of the inclined plate 1403 is lower than the horizontal plate 1402. The included angle formed between the inclined plate 1403 and the horizontal plate 1402 is an obtuse angle. The horizontal plate 1402 is parallel to the conveying table 101 and higher than the conveying roller path. The upper surface of the horizontal plate 1402 forms a bearing surface.

[0106] It should be noted that the height of the lowest position of the inclined plate 1403 is higher than the conveying roller path on the conveying table 101, so that a gap for the round bar to pass through is formed between the lowest position of the inclined plate 1403 and the conveying roller path of the conveying table 101. Since the height of the horizontal plate 1402 is higher than that of the inclined plate 1403, the height difference between the horizontal plate 1402 and the conveying roller path of the conveying table 101 is sufficient for the round bar to pass through.

[0107] Figure 4 The rotating frame 802 on the tail stock pusher in is placed on the horizontal plate 1402 of the deflecting member 14. Since the height difference between the horizontal plate 1402 and the conveying roller path of the conveying table 101 is sufficient for the long round bar to pass through, the tail stock pusher will not affect the movement of the long round bar towards the cold shear 1, and the long round bar smoothly passes through the bottom of the rotating frame 802.

[0108] When the linear drive device 11 drives the moving frame 6 to drive the tail stock pusher towards the cold shear 1, causing the rotating frame 802 to disengage from the deflecting member 14, the rotating frame 802 returns to its natural state. At this time, the rotating frame 802 is in an inclined state, that is, the end of the rotating frame 802 away from the frame body 801 is lower than its other end. The height difference between the end of the rotating frame 802 away from the frame body 801 and the conveying table 101 is not sufficient for the long round bar to pass through. In this way, when the linear drive device 11 drives the moving frame 6 to drive the tail stock pusher to continue moving into the cold shear 1, the bottom end of the rotating frame 802 will eventually push the long round bar to continuously move towards the cold shear 1 on the raised platform on the right side of the conveying table 101, so that the left end of the long round bar tail stock gradually passes through the first cutting knife groove of the lower cutting knife until the round bar tail stock is pushed into the waste guide groove.

[0109] In this embodiment, when the long round bar is cut multiple times and only the tail stock remains, at this time, the left end of the tail stock rests on the raised platform on the right side of the conveying table 101 and the raised platform on the top of the workbench 102, while the right end of the tail stock rests in the first cutting knife groove of the lower cutting knife. At this time, by starting the first motor 1102, the first rotating shaft and the second rotating shaft are driven to rotate simultaneously through the transmission of the gearbox 1101. The simultaneous rotation of the first rotating shaft and the second rotating shaft drives the two traveling gears 1104 to rotate simultaneously, so that the traveling gears 1104 move along the length direction of the toothed plate 1105, driving the moving frame 6 and the tail stock pusher to move towards the cold shear 1 together. When the rotating frame 802 no longer contacts the guide plate 1202, at this time, the rotating frame 802 rotates relative to the frame body 801 under the action of gravity, so that the rotating frame 802 is in an inclined state, that is, the end of the rotating frame 802 away from the frame body 801 is lower than its other end. As the moving frame 6 and the tail stock pusher continue to move towards the cold shear 1, the tail stock pusher gradually approaches and pushes the round bar tail stock to push the long round bar tail stock into the waste guide groove.

[0110] It can be seen that in this embodiment, there is no need for manual use of a long rod to push the oval bar tailstock, and automatic tailstock pushing can be achieved, greatly improving the work efficiency and saving more time and effort.

[0111] Optionally, as Figure 14 and Figure 15 shown, a plurality of fixing pieces 805 are installed inside the rotating frame 802. The plurality of fixing pieces 805 are uniformly arranged along the length direction of the rotating frame 802, and the fixing pieces 805 are fixedly connected to the connecting shaft 803. Further, there is an opening on the side of the rotating frame 802 away from the frame 801. A circular shaft is installed between every two adjacent fixing pieces 805, and a roller 806 is sleeved on each circular shaft. The roller 806 is located at the opening on the side of the rotating frame 802 away from the frame 801.

[0112] In this way, when the rotating frame 802 is no longer in contact with the guiding plate 1202, the rotating frame 802 gradually rotates to an inclined state, so that the roller 806 in the rotating frame 802 falls on the raised platform on the right side of the conveying table 101, so that the rotating frame 802 can move on the raised platform to more conveniently push the tailstock.

[0113] Preferably, as Figure 6 shown, the moving frame 6 includes a frame in a shape of a Chinese character 'hui' and a triangular support frame mounted on the top of the 'hui'-shaped frame. Considering that if the length of the remaining round bar tailstock is relatively long, it may occur that the tailstock pushing member installed on the right side of the moving frame 6 cannot push. Therefore, a tailstock pushing member is also installed on the left side of the moving frame 6.

[0114] As Figure 2 and Figure 3 shown, in order to facilitate distinction, the two tailstock pushing members are respectively named the first tailstock pushing member 8 and the second tailstock pushing member 13. Among them, the first tailstock pushing member 8 is installed on the right side of the moving frame 6, and the second tailstock pushing member 13 is installed on the left side of the moving frame 6.

[0115] In this way, if the left end of the round bar tailstock exceeds the first tailstock pushing member 8, that is, the left end of the round bar tailstock is located on the left side of the first tailstock pushing member 8, the first tailstock pushing member 8 cannot play a role at this time. At this time, the second tailstock pushing member 13 can be used to push the round bar tailstock. Of course, a deflecting member 14 cooperating with the second tailstock pushing member 13 is also installed on the tabletop of the conveying table 101.
