[0002] In industrial production, the production industry involves the cutting process of steel bars and steel pipes. Because they are long and heavy, the cutting efficiency is low when they are cut manually, and the labor intensity is high. With the continuous development of technology, some technical solutions that can realize the automatic cutting of rods have also appeared on the market, such as the Chinese utility model patent submitted by the applicant of this application on December 28, 2022, with application number 202223510082.3 and patent name "A circular saw device for cutting steel bars". However, the existing technology including this technical solution generally has the following problems: because the length of the rod is long before cutting, it is difficult to ensure that the axis of the rod is a straight line, that is, the rod itself generally has a certain curvature, and the bending direction of the rod is difficult to determine. Since it is generally necessary to clamp and fix the rod during cutting, the clamping mechanism in the traditional cutting device is relatively fixed in its direction of activity and the distance moved during clamping when it is in action. When there is a certain curvature in the rod, it is difficult to ensure the reliability of clamping. Utility Model Content

DETAILED DESCRIPTION

[0031] Figures 1 to 14 It is the best embodiment of the utility model, and the following Figures 1 to 14 The utility model is further described.

[0032] like Figure 1 As shown, a rod cutting device includes a cutting device 5, wherein the two ends of the cutting device 5 are a feeding end and a discharging end, respectively. A feeding mechanism 6 is arranged at the feeding end of the cutting device 5, and a discharging conveyor 2 is arranged at the discharging end of the cutting device 5. The feeding mechanism 6 is formed by connecting a plurality of independently arranged feeding conveyors end to end. At the two ends of the feeding mechanism 6, unpacking racks 7 are arranged on the same side of the two feeding conveyors at the end. The unpacking racks 7 are arranged vertically with the feeding conveyors, and the two unpacking racks 7 are connected with the corresponding two feeding conveyors respectively. After the whole raw material rod 1 is unpacked at the unpacking racks 7, the raw material rod 1 is transferred to the feeding mechanism 6, and is sent into the cutting device 5 under the joint action of all the feeding conveyors in the feeding mechanism 6.

[0033] The whole raw material rod 1 is cut into a predetermined length in the cutting device 5 to obtain a finished rod 3. After being output by the cutting device 5, the finished rod 3 is sent to the discharge conveyor 2. At the end of the discharge conveyor 2, there is a turning mechanism to transfer the finished rod 3. A sizing mechanism 4 is also provided at the discharge end of the cutting device 5. In this rod cutting device, the specific implementation method and working principle of the sizing mechanism 4 are the same as those in the prior art. See the technical solution disclosed in the Chinese utility model patent filed by the applicant of this application on July 22, 2020, with application number 202021465475.5 and patent name "A Sizing Mechanism for a Sawing Machine", which will not be repeated here.

[0034] like Figure 2 As shown, the discharge conveyor 2 includes a discharge conveyor frame 13 arranged at the outlet of the cutting device 5, and the discharge conveyor frame 13 is arranged along the transmission direction of the finished rod 3. A plurality of discharge rollers 9 are arranged at intervals on the surface of the discharge conveyor 13. A discharge drive motor 11 is arranged below the end of the discharge conveyor frame 13, and all the discharge rollers 9 are connected in sequence at the motor shaft of the discharge drive motor 11 (or through a reducer) through a sprocket chain mechanism known in the art, and the finished rod 3 is placed on the surface of the discharge roller 9 and moves under the drive of the discharge drive motor 11. The above-mentioned sizing mechanism 4 is fixed to the side of the discharge conveyor frame 13.

[0035] At the end of the discharging conveyor frame 13, a discharging baffle 10 is erected, and two turning racks are arranged at intervals on the front side of the discharging baffle 10: a first turning rack 8 and a second turning rack 12, and the first turning rack 8 and the second turning rack 12 are respectively erected above the discharging conveyor frame 13. The first turning rack 8 and the second turning rack 12 are respectively hinged to the two ends of the discharging conveyor frame 13, and oil cylinders for driving the first turning rack 8 and the second turning rack 12 to rotate are respectively arranged in the discharging conveyor frame 13. When the piston rod of the corresponding oil cylinder is output, the first turning rack 8 or the second turning rack 12 swings to both sides of the discharging conveyor frame 13. Since the ends of the raw material rod 1 often have quality defects such as burrs, the ends of the raw material rod 1 need to be separately recovered after cutting. By setting a first turning rack 8 and a second turning rack 12, the first turning rack 8 (or the second turning rack 12) turns the end containing the end of the raw material rod 1 to one side of the discharge conveyor 2, and the several sections of finished rods 3 in the middle part of the raw material rod 1 after cutting are turned to the other side of the discharge conveyor 2 by the second turning rack 12 (or the first turning rack 8), thereby realizing the separate recovery of the finished rods 3 after the raw material rod 1 is cut.

[0036] The feed conveyor includes three independently arranged parts: a translation component, a transfer component and a feeding component. The translation component and the transfer component are arranged vertically with the feeding component respectively. The translation components in the feed conveyor at both ends of the feeding mechanism 6 are docked with the unpacking rack 7 respectively. The translation component and the transfer component are arranged alternately, and the end of the transfer component is docked with the feeding component. The feeding components in all the feed conveyors are docked head to tail to form a conveying path for the raw material rod 1. After the raw material rod 1 is unpacked in the unpacking rack 7, it is transferred to the translation components in all the feed conveyors at the same time through the translation components in the feed conveyors at both ends. And it is transferred to the transfer components of all the feed conveyors under the drive of all the translation components, and then the transfer components in all the feed conveyors transfer the raw material rod 1 again to the conveying path composed of the feeding components in all the feed conveyors, and then sent into the cutting device 5.

[0037] like Figure 3~4 As shown, the translation assembly includes a translation frame 23, a translation conveyor belt 22 is arranged on the top of the translation frame 23, a driving pulley and a driven pulley are arranged on both sides of the translation conveyor belt 22, and the translation conveyor belt 22 is sleeved outside the driving pulley and the driven pulley. A translation drive motor 21 is arranged at the bottom of the translation frame 23, and the translation drive motor 21 is connected to the driving pulley.

[0038] The feeding assembly includes a feed conveyor frame 19, on the upper surface of which a plurality of feed rollers 18 are spaced apart, a feed drive motor 20 is disposed at the lower portion of the feed conveyor frame 19, and all the feed rollers 18 are connected in sequence at the motor shaft of the feed drive motor 20 (or through a reducer) through a sprocket chain mechanism well known in the art, and the raw material rod 1 is driven by the feed rollers 18 in all the feed assemblies to enter the cutting device 5.

[0039] At least one feed roller 16 is also provided on the upper part of the feed conveyor frame 19, and two feed rollers arranged in a "V" shape are provided inside the feed roller 16. The feed roller 16 supports the raw material bar 1 to assist in conveying. A plurality of feed guide columns 17 are also provided at intervals at both ends of the upper surface of the feed conveyor frame 19 to guide the raw material bar 1.

[0040] The transfer assembly includes a transfer rack, which is staggered with a translation rack 23, and is arranged vertically with a feed conveyor rack 19, and the transfer rack and the feed conveyor rack 19 are butted end to end. A translation cylinder 24 is arranged on the surface of the transfer rack, and the piston rod of the translation cylinder 24 faces one side of the feeding assembly. Transfer rails are respectively arranged on both sides of the upper surface of the transfer rack, and a translation plate 15 is slidably mounted on the surface of the transfer rails on both sides. The translation plate 15 is mounted on the end of the piston rod of the translation cylinder 24, and the translation plate 15 moves back and forth along the transfer rack driven by the translation cylinder 24.

[0041] A lifting cylinder is fixed at the bottom of the translation plate 15, and the piston rod of the lifting cylinder is vertically upward, and the piston rod of the lifting cylinder passes through the translation plate 15 from bottom to top. A lifting block 14 is fixed on the top of the piston rod of the lifting cylinder, and a "V"-shaped groove for clamping the raw material rod 1 is provided on the surface of the lifting block 14. Translation limit frames 25 are respectively provided on both sides of the transfer frame, and the translation limit frames 25 on both sides are symmetrically fixed. On the side of the translation limit frame 25 facing away from the feeding assembly is a tilting rod, and the bottom of the tilting rod is combined with the transfer frame to form an angle for limiting the raw material rod 1.

[0042] After the raw material bar 1 is unpacked in the unpacking rack 7, it is further transferred to all the translational assemblies through the translational assemblies in the feeding conveyors at both ends. And it is transferred to the side of the feeding assembly under the drive of the translational conveyor belt 22 in all the translational assemblies, and is first transferred to the surface of the transfer assembly during the transfer process. A detection element (such as a proximity switch) is provided at the translational limit frame 25 in the transfer assembly. When the detection element detects the raw material bar 1, the translational drive motor 21 in the corresponding feeding conveyor stops working until the translational drive motor 21 in all the feeding conveyors stops working. At this time, it means that the raw material bar 1 is moved as a whole to the translational limit frame 25 in the transfer assembly. Since the axis of the raw material bar 1 will have a certain angle deviation with the feeding mechanism 6 after being released from the unpacking rack 7, the control of the translational drive motor 21 by the detection element can ensure that the raw material bar 1 corrects the angle deviation between the raw material bar 1 and the feeding mechanism 6 at the transfer assembly.

[0043] After the raw material bar 1 is positioned as a whole at the translation limit frame 25, the piston rod of the lifting cylinder at the bottom of the translation plate 15 is output, and when the lifting block 14 contacts the raw material bar 1, the raw material bar 1 is clamped on the surface of the lifting block 14. And through multiple lifting cylinders, the raw material bar 1 is lifted to a certain height (higher than the translation limit frame 23). Then the piston rods of all translation cylinders 24 are output, and the lifted raw material bar 1 is output and sent to the top of the feeding assembly. Finally, the piston rod of the lifting cylinder is reset, and the raw material bar 1 is transferred to the surface of the feed roller 18 on the surface of the conveying assembly. The raw material bar 1 is driven by the feed roller 18 to be sent into the cutting device 5.

[0044] like Figures 5 and 6 As shown, the cutting device 5 includes an outer cover 27, and a defogger 26 is arranged on the top of the outer cover 27. The cutting device 5 includes a cutting base 31, and a cutting conveying assembly is arranged in the middle of the upper surface of the cutting base 31. Through the cutting conveying assembly, the auxiliary feeding mechanism 6 realizes the transmission of the raw material rod 1 in the cutting device 1. A cutting machine 28 is arranged on the rear side of the cutting conveying assembly, and a chip conveyor 38 is arranged on the side of the cutting machine 28.

[0045] On the side of the cutting and conveying assembly facing the entrance of the raw material bar 1, a lifting assembly 34, a feeding horizontal clamping assembly 33 and a feeding vertical clamping assembly 32 are sequentially arranged. The feeding horizontal clamping assembly 33 and the feeding vertical clamping assembly 32 are used to fix the raw material bar 1 horizontally and vertically on the feeding side. The feeding vertical clamping assembly 32 is fixed to the end of the feeding conveyor near the cutting device 5 and is located on the outside of the outer cover 27 as a whole. On the side of the cutting and conveying assembly facing the exit of the raw material bar 1, a follow-up clamping assembly 30 and a discharge vertical clamping assembly 35 are sequentially arranged, and the discharge vertical clamping assembly 35 is fixed at the exit of the follow-up clamping assembly 30. The follow-up clamping assembly 30 and the discharge vertical clamping assembly 35 are used to fix the raw material bar 1 horizontally and vertically on the discharge side.

[0046] Combination Figure 7-8 A cutter base 37 is provided on the surface of the base 31, and the cutter base 37 is located at the rear side of the cutting and conveying mechanism. The surface of the cutter base 37 is an inclined surface, and two guide rails are arranged side by side on the surface of the inclined surface of the cutter 28, and the cutter 28 is slidably mounted on the surface of the cutter base 37 through the two guide rails. An oil cylinder is provided on the rear side of the cutter base, and the piston rod of the oil cylinder is fixed to the rear of the cutter 28, and the cutter 28 is controlled by the oil cylinder to slide up and down along the inclined surface of the cutter base 37. When the cutter 28 slides along the inclined surface of the cutter base 37, the saw blade of the cutter 28 gradually contacts with the raw material bar 1 and cuts.

[0047] The cutting and conveying mechanism includes a cutting and conveying motor 40, a reducer is arranged at the motor shaft of the cutting and conveying motor 40, two cutting rollers 39 are arranged side by side on the side of the cutting and conveying motor 40, and the cutting and conveying motor 40 is connected to the two cutting rollers 39 in sequence through the reducer and the sprocket chain mechanism.

[0048] The lifting assembly 34 includes a lifting drive motor 42, a screw lift is provided at the motor shaft of the lifting drive motor 42, and a lifting plate 36 is horizontally provided at the top of the lifting rod of the screw lift. Because the raw material bar 1 is long before cutting, it is difficult to ensure that its axis is a straight line. According to the above, after the raw material bar 1 is fixed horizontally and vertically on the feeding side and the discharging side respectively before cutting, if the raw material bar 1 has a certain bending, the raw material bar 1 itself will have a certain elastic force. At the moment when the cutting machine 28 cuts off the raw material bar 1, the raw material bar 1 is prone to cause its own elastic force and cause the rod to jump. If the cutting surface of the raw material bar 1 is against the side of the saw blade of the cutting machine 28 after the rod jump occurs, it will hinder the rotation of the saw blade and cause damage to the motor of the cutting machine 28.

[0049] In the rod cutting device, the lifting plate 36 is raised by the lifting drive motor 42 before cutting. When the lifting plate 36 is against the bottom of the raw material rod 1 and cannot continue to rise, the motor shaft of the lifting drive motor 42 cannot rotate, causing its working current to rise. By detecting the working current of the lifting drive motor 42, it is determined whether the lifting plate 36 has achieved reliable contact with the raw material rod 1. After the lifting plate 36 and the raw material rod 1 are in reliable contact, the cutting machine 28 performs cutting. Since the raw material rod 1 is limited by the lifting plate 36 in advance, at the moment when the cutting machine 28 cuts the raw material rod 1, the raw material rod 1 is prevented from contacting the saw blade of the cutting machine 28 due to the release of its own elastic force, thereby avoiding damage to the cutting machine 28.

[0050] The feed horizontal clamping assembly 33 includes two horizontal clamping plates 43 arranged opposite to each other. After the raw material bar 1 enters the cutting device 5, it passes between the two horizontal clamping plates 43. One of the two horizontal clamping plates 43 is a fixed clamping plate, and the other is a movable clamping plate. A horizontal clamping oil cylinder 41 is arranged on the side of the movable clamping plate. The piston rod of the horizontal clamping oil cylinder 41 is connected to the movable clamping plate. When the piston rod of the horizontal clamping oil cylinder 41 is output, the raw material bar 1 is clamped in the horizontal direction on the feed side.

[0051] like Fig. 9 As shown, the feed vertical clamping assembly 32 includes a feed fixing frame 48, which is mounted above the discharge end of the feed conveyor near the cutting device 5. Fixed plates 51 are respectively provided on both sides of the lower end of the feed fixing frame 48, and are fixed to both sides of the feed conveyor frame 19 in the corresponding feed conveyor through the fixed plates 51 on both sides.

[0052] A feed upper clamping oil cylinder 45 is provided on the top beam of the feed fixing frame 48, and the piston rod of the feed upper clamping oil cylinder 45 is vertically downward and penetrates the top beam of the feed fixing frame 48. A feed guide shaft 46 is provided on both sides of the feed upper clamping oil cylinder 45, and the two feed guide shafts 46 penetrate the top beam of the feed fixing frame 48 respectively, and are fixed at the upper part of the two feed guide shafts 46 by the feed connecting plate 44. A feed pressing plate 47 is provided at the lower part of the top beam of the feed fixing frame 48, and the feed pressing plate 47 is fixed to the piston rod of the feed upper clamping oil cylinder 45 and the lower ends of the two feed guide shafts 46 at the same time.

[0053] A feed lower clamping oil cylinder 50 is provided on one side of the lower part of the feed fixing frame 48, and the piston rod of the feed lower clamping oil cylinder 50 passes through the side beam on one side of the feed fixing frame 48, and a feed clamping inclined plate 49 is fixed at the end of its piston rod, and the feed clamping inclined plate 49 is located below the feed pressing plate 47. When the piston rods of the feed upper clamping oil cylinder 45 and the feed lower clamping oil cylinder 50 are output, the raw material rod 1 is clamped from the upper and lower sides from the feed side through the feed pressing plate 47 and the feed clamping inclined plate 49 respectively.

[0054] like Fig.10 As shown, the material discharging vertical clamping assembly 35 includes an upper material discharging fixing frame 58 and a lower material discharging fixing frame 57 which are arranged at intervals. An upper material discharging clamping oil cylinder 52 is arranged on the upper surface of the upper material discharging fixing frame 58. The piston rod of the upper material discharging clamping oil cylinder 52 is vertically downward and penetrates the upper material discharging fixing frame 58. A material discharging guide shaft 53 is arranged on both sides of the upper material discharging clamping oil cylinder 45. The two material discharging guide shafts 53 penetrate the upper material discharging fixing frame 58 respectively and are fixed at the upper part of the two material discharging guide shafts 53 by a material discharging connecting plate 59. A material discharging pressing plate 54 is arranged at the lower part of the upper material discharging fixing frame 58. The material discharging pressing plate 54 is fixed to the piston rod of the upper material discharging clamping oil cylinder 52 and the lower ends of the two material discharging guide shafts 53 at the same time.

[0055] A discharging lower clamping oil cylinder 56 is provided on the side of the discharging lower fixed frame 57, and a discharging clamping inclined plate 55 is fixed to the end of the piston rod of the discharging lower clamping oil cylinder 56. When the piston rods of the discharging upper clamping oil cylinder 52 and the discharging lower clamping oil cylinder 56 are output, the raw material rod 1 is clamped from the upper and lower sides from the discharging side through the discharging pressing plate 54 and the discharging clamping inclined plate 55 respectively.

[0056] like Figures 11-12 As shown, the follower clamping assembly 30 includes a follower fixing frame 62, which is mounted on the surface of the base 31. The raw material rod 1 passes through the opening at the bottom of the follower fixing frame 62, and a feed guide plate 64 is tiltedly arranged on both sides of the feed end of the bottom opening of the follower fixing frame 62. The discharge lower fixing frame 57 and the discharge upper fixing frame 58 in the above-mentioned discharge vertical clamping assembly 35 are respectively fixed to the side of the follower fixing frame 62, and the discharge lower fixing frame 57 and the discharge upper fixing frame 58 are respectively located on the upper and lower sides of the bottom opening of the follower fixing frame 62.

[0057] Combination Figures 13 and 14 A horizontal top plate 61 is arranged on the top of the follower fixing frame 62, and a bottom plate 67 is arranged horizontally below the top plate 61. Limiting plates 66 are vertically fixed at both ends of the top plate 61 and the bottom plate 67, and limiting openings 65 are respectively opened in the middle of the limiting plates 66 on both sides. A follower clamping oil cylinder 60 is arranged between the top plate 61 and the bottom plate 67, and a follower clamping claw 63 is respectively fixed at the end of the output end of the follower clamping oil cylinder 60 and the end of the piston rod of the follower clamping oil cylinder 60, and the two follower clamping claws 63 extend downward to the opening at the bottom of the follower fixing frame 62. The limiting plates 66 on both sides limit the follower clamping claws 63 on both sides respectively.

[0058] As can be seen from the above, due to the large length of the raw material rod 1, it is difficult to ensure that its axis is a straight line. When the raw material rod 1 is clamped by the follower clamping oil cylinder 56, if the follower clamping claw 63 at one end of the piston rod of the follower clamping oil cylinder 60 contacts the raw material rod 1 first, the follower clamping claw 63 and the raw material rod 1 are in a relatively fixed state, and at this time, the body of the follower clamping oil cylinder 56 will approach the raw material rod 1 with the hydraulic pressure until it contacts the other side of the raw material rod 1; if the follower clamping claw 63 at one end of the body of the follower clamping oil cylinder 60 contacts the raw material rod 1 first, the follower clamping claw 63 at one end of the piston rod will be driven to contact the raw material rod 1 by the same logic. Therefore, through the follower clamping assembly 30, it can be ensured that the raw material rod 1 is fixed from both ends in the horizontal direction on the discharge side of the cutting device 5.

[0059] After the follow-up clamps 63 on both sides clamp the raw material rod 1, hydraulic oil is continuously introduced into the follow-up clamping cylinder 60. At this time, the lower parts of the follow-up clamps 63 on both sides maintain a constant distance under the action of the raw material rod 1, while the upper parts of the follow-up clamps 63 on both sides continue to approach under the action of the follow-up clamping cylinder 60. At this time, the upper parts of the follow-up clamps 63 on both sides are stuck between the top plate 61 and the bottom plate 67, thereby avoiding relative displacement between the raw material rod 1 and the follow-up clamping assembly 30, thereby achieving the clamping of the raw material rod 1.

[0060] The specific working process and working principle are as follows:

[0061] After the raw material bar 1 is unpacked in the unpacking rack 7, it is further transferred to all the translational components through the translational components in the feeding conveyors at both ends. And it is transferred to the side of the feeding component under the drive of the translation conveyor belt 22 in all the translational components, and is first transferred to the surface of the transfer component during the transfer process. After the raw material bar 1 is located at the translation limit frame 25 as a whole, the piston rod of the lifting cylinder at the bottom of the translation plate 15 is output, and when the lifting block 14 contacts the raw material bar 1, the raw material bar 1 is clamped on the surface of the lifting block 14. And through multiple lifting cylinders, the raw material bar 1 is lifted to a height higher than the translation limit frame 23. Then the piston rods of all the translation cylinders 24 are output, and the lifted raw material bar 1 is output and sent to the top of the feeding component. Finally, the piston rod of the lifting cylinder is reset, and the raw material bar 1 is transferred to the surface of the feeding roller 18 on the surface of the conveying component. The raw material bar 1 is sent into the cutting device 5 under the drive of the feeding roller 18.

[0062] After entering the cutting device 5, the raw material bar 1 passes through the cutting device 5 and is sent to the discharge conveyor 2 under the auxiliary drive of the cutting conveyor mechanism 29. When the length of the raw material bar 1 output reaches a predetermined length, it is positioned under the action of the length-fixing mechanism 4 on the side of the discharge conveyor 2. At this time, the discharge conveyor 2, the feeding mechanism 6 and the cutting conveyor mechanism 29 stop running.

[0063] The upper clamping oil cylinder 45 and the lower clamping oil cylinder 50 in the horizontal clamping assembly 33 of the cutting device 5 are actuated, and the raw material bar 1 is fixed in the vertical direction on the feeding side through the feeding pressure plate 47 and the feeding clamping inclined plate 49. The horizontal clamping oil cylinder 41 is actuated, and the raw material bar 1 is fixed in the horizontal direction on the feeding side through the horizontal clamping plate 43. At the same time, the upper clamping oil cylinder 52 and the lower clamping oil cylinder 56 in the vertical clamping assembly 35 of the discharging are actuated, and the raw material bar 1 is fixed in the vertical direction on the discharging side through the discharging pressure plate 54 and the discharging clamping inclined plate 55; the follow-up clamping oil cylinder 60 in the follow-up clamping assembly 30 is actuated, and the raw material bar 1 is fixed in the horizontal direction on the discharging side through the follow-up clamping claw 63. Finally, the lifting drive motor 42 in the lifting assembly 34 is actuated, and the bottom of the raw material bar 1 is lifted through the lifting plate 36.

[0064] When the cutter 28 slides along the inclined surface of the cutter base 37 under the action of the rear oil cylinder, the saw blade of the cutter 28 gradually contacts the raw material bar 1 and cuts. After the cutting is completed, the cutter 28 rises under the action of the rear oil cylinder and separates from the raw material bar 1 to complete the cutting. After the raw material bar 1 is cut, the finished bar 3 is obtained. Then the lifting assembly 34, the feeding horizontal clamping assembly 33, the feeding vertical clamping assembly 32, the follower clamping assembly 30 and the discharging vertical clamping assembly 35 release the clamping of the finished bar 3. The finished bar 3 is output under the drive of the discharging conveyor 2.

[0065] After the finished rods 3 are transferred to the discharge baffle 10 at the end of the discharge conveyor 2 , the finished rods 3 are transferred by the first turning rack 8 or the second turning rack 12 .
