Description

[0002] In the traditional power tower angle steel production line, the angle steel cutting device mainly includes: positive V-shaped power roller conveyor line, magnetic suction flip mechanism, inverted V-shaped power roller cutting processing conveyor line and positioning stop mechanism, dual robot plasma cutting device and other equipment.

[0003] The existing angle steel cutting process mainly has the following technical defects:

[0004] 1. When using a traditional positive V-shaped power roller conveyor line, the conveying driving force is provided by the friction between the contact surface of the conveyor roller and the angle steel. During the start-up and speed-up stage of the conveyor line, due to the small static friction or the uneven contact surface of the angle steel, the angle steel is not fully in contact with the power roller, etc., there will be slippage, resulting in too long transportation time for the angle steel; 2. When the dual-robot plasma angle cutting device encounters angle steel that requires double-end angle cutting, it adopts a serial processing method, that is, the end angle cutting processing is completed first, and then it is transported to the front processing position through the angle cutting processing conveyor line, and the front end angle cutting processing is completed after the angle steel is re-positioned.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0040] like Figure 1 As shown, the angle steel intelligent double-end laser angle cutting processing system includes a feeding channel 2, a material pressing and conveying mechanism 4 is arranged above the left end of the feeding channel 2, and the material pressing and conveying mechanism 4 is fixedly installed on the ground through a frame 5 below, a turning mechanism 1 is arranged at the front side of the feeding channel 2, and a transverse conveying mechanism 6 is arranged at the front side of the turning mechanism 1, and the laser angle cutting mechanism 3 is installed above the transverse conveying mechanism 6. The length directions of the feeding channel 2, the turning mechanism 1 and the transverse conveying mechanism 6 are arranged in parallel.

[0041] like Figure 2 , 3As shown in Figures 4 and 5, the frame 5 is a profile welded frame structure, including a bottom rectangular frame placed on the ground and an upper side mounting frame fixedly mounted on the upper left side of the bottom rectangular frame, and the frame 5 plays a role of fixed installation and support. The press conveying mechanism 4 includes a press base 11, which is fixedly mounted on the inner side of the upper end of the upper side mounting frame. A pair of parallel vertical guide rails are arranged at both ends of the front side of the press base 11. A press slide slidably connected to the vertical guide rails is movably arranged at the front end of the press base 11. The lower end of the press slide is connected to the upper end of the piston rod of the second adjustment cylinder 19. The bottom of the second adjustment cylinder 19 is fixedly mounted on the bottom rectangular frame, and the second adjustment cylinder 19 is used to control the press slide to move up and down. A driven base 8 is fixedly arranged at the front end of the press slide, and the driven base 8 moves up and down with the press slide. A plurality of groups of vertical guide rails are arranged at the front end of the driven base 8, and a roller base 9 is slidably connected to each group of vertical guide rails. A plurality of first adjusting cylinders 7 are fixedly arranged on the upper end of the driven base 8. The push rods of the first adjusting cylinders 7 are connected to the roller base 9 through floating joints, so as to control the roller base 9 to move up and down.

[0042] The lower end of each roller base 9 is provided with a chain drive assembly 20. The sprocket in the chain drive assembly 20 can adopt a double-row sprocket, which is more stable and has higher transmission efficiency than a single sprocket. The front end of the roller base 9 is provided with a reduction motor 12. The output shaft of the reduction motor 12 is connected to the chain drive assembly 20. The front end of the rotating shaft of each chain drive assembly 20 is rotatably connected to the pressure roller 10. A cylindrical roller group 18 is provided below the pressure roller 10. The cylindrical roller group 18 is fixedly installed at the upper end of the bottom rectangular frame. The cylindrical roller group 18 is provided with two rows, which are parallel and symmetrically distributed. The cylindrical rollers on the two rows of cylindrical roller groups 18 are all tilted. The two opposite cylindrical rollers form a structure that matches the positive V-shaped angle steel. The two rows of cylindrical roller groups 18 are used to support and convey the angle steel. A push base is provided between the two rows of cylindrical roller groups 18. An inner thread hole is provided at the lower end of the push base, which is connected to the screw extending from the rotating shaft of the push motor 17. The push motor 17 is fixedly mounted on the right end of the bottom rectangular frame, and the push base can be controlled to move left and right by the push motor 17. The upper end of the push base is rotatably connected to the right end of the push claw 21 through a pin shaft. Because the connection point is close to the right end of the push claw 21, the left end of the push claw 21 sinks due to gravity, and the right end of the push claw 21 is lifted to form a slope for the angle steel to pass through. The lower surface of the push base is slidably mounted on the push guide rail, which is fixedly mounted on the bottom rectangular frame. The push guide rail supports and limits the push base. A first proximity switch is installed on the bottom rectangular frame on the left side of the pressure roller 10. The first proximity switch is used to detect whether the angle steel has reached the pressure roller 10. A support frame 13 is arranged above the cylindrical roller group 18 at the right end, and the lower end of the support frame 13 is fixedly connected to the bottom rectangular frame. A press cylinder 14 is fixedly installed on the upper end of the support frame 13, and a position sensor is installed on the bottom rectangular frame on the left side of the press cylinder 14. A connecting rod 15 is arranged below the press cylinder 14. The leftmost end of the connecting rod 15 is rotatably connected to the support frame 13 through a pin, and the middle part of the connecting rod 15 is movably connected to the push rod of the press cylinder 14. A damping wheel 16 is arranged at the rightmost end of the connecting rod 15, which can drive the damping wheel 16 to swing and press the angle steel by controlling the press cylinder 14. A second proximity switch is installed at the rightmost end of the bottom rectangular frame, and the second proximity switch is used to detect whether the angle steel has been pushed out of the frame 5 as a whole and transported to the feeding channel 2 as a whole. A first photoelectric sensor is installed on the frame 5 below the push claw 21, and the first photoelectric sensor is used to detect whether the left end of the angle steel has passed through the push claw 21 as a whole.

[0043] like Figure 5 As shown, the left end of the feeding channel 2 is close to the right end of the pressing and conveying mechanism 4, and the feeding channel 2 includes a plurality of feeding brackets fixedly mounted on the ground, and a plurality of positive V-shaped non-powered rollers are rotatably mounted above the feeding brackets, and the plurality of non-powered rollers form a feeding roller path for the angle steel to pass through. A certain gap is left between two adjacent feeding brackets for placing the equally divided disc 22 in the turning mechanism 1.

[0044] like Figure 6 , 7 As shown in Figure 8, the flip mechanism 1 includes a flip shaft 24, an equally divided disc 22 and a flip motor 26. The flip shaft 24 is supported by a plurality of vertical flip brackets 23. The flip shaft 2 is rotatably mounted on the top of the flip bracket 23 in a horizontal direction. The bottom of the flip bracket 23 is fixedly connected to a horizontal bracket bottom plate. An anchor screw through hole is provided at the edge of the bracket bottom plate. The flip bracket 23 is fixedly mounted on the ground by passing the anchor screw through the anchor screw through hole to ensure the support stability of the flip bracket 23. A bearing seat is fixedly mounted on the top of the flip bracket 23. The flip shaft 2 is rotatably connected to the bearing seat. The bearing seat can reduce the friction force when the flip shaft 2 rotates. A flip motor 26 is fixedly arranged at the right end of the flip shaft 24, and the rotating shaft of the flip motor 26 is connected to the right end of the flip shaft 24 through a motor reducer 25 and a coupling. A support frame is fixedly installed below the motor reducer 25. A plurality of equally divided discs 22 are fixedly arranged on the flip shaft 24, and the equally divided discs 22 rotate synchronously with the flip shaft 24. The spacing between each equally divided disc 22 gradually increases from left to right. The spacing between the equally divided discs 22 at the left end is set relatively small to prevent the shorter angle steel from being suspended in the air when flipping. Such an arrangement structure of the equally divided discs 22 can ensure that angle steels of various lengths can be effectively supported to avoid the angle steels being suspended too long.

[0045] The outer circumference of the equally divided circular disc 22 is evenly distributed with eight notches for grabbing and placing angle steels. The notches for grabbing and placing angle steels are used to grab and place angle steels and then cut the angle steels into inverted V shapes using a laser angle cutter 38. The equally divided circular disc 22 can grab and flip multiple angle steels at the same time. A limiting protrusion is integrally formed on the upper right end of the notch for grabbing and placing angle steels. The protruding direction of the limiting protrusion is consistent with the rotation direction of the equally divided circular disc. The limiting protrusion makes the angle steel grabbing more stable. The surface of the equally divided circular disc 22 is evenly distributed along the center of the circle with a number of relatively large-diameter weight-reducing holes. The weight-reducing holes are used to reduce the weight of the equally divided circular disc 22 itself. Eight relatively small-diameter detection holes 27 are evenly distributed on the outer side of the weight-reducing holes along the center of the circle. A second photoelectric sensor 28 is fixedly provided on the right side of the equally divided circular disk 22 in the middle position. Every time the second photoelectric sensor 28 detects that a detection hole 27 passes by, it means that the equally divided circular disk 22 has rotated one-eighth of a circle and needs to pause intermittently. The second photoelectric sensor 28 cooperates with the detection hole 27 to realize automatic control of the intermittent circular motion of the equally divided circular disk 22 through the host computer.

[0046] like Fig. 9 , 10As shown, the transverse conveying mechanism 6 includes a chain plate conveyor 30 and a conveying motor 31. In this embodiment, nine chain plate conveyors 30 are provided. The angle steel is conveyed through a sprocket chain, and the chain plate conveyor 30 is driven by the conveying motor 31. The conveying motor 31 is fixedly installed on the ground in the middle section of the transmission shaft 32. The output shaft of the conveying motor 31 is connected to the driving pulley in the middle of the transmission shaft 32 through a synchronous belt. Nine driven sprockets corresponding to the chain plate conveyor 30 are provided on the transmission shaft 32. The driven sprockets are connected to the chain plate conveyor belt of the chain plate conveyor 30. The chain plate conveyor belt is driven to rotate synchronously by the conveying motor 31 to convey the angle steel. A primary positioning block 29 is fixedly provided in the middle position of the chain plate conveyor 30. A block cylinder 36 is provided below the primary positioning block 29. The primary positioning block 29 is connected to the push rod of the block cylinder 36. A primary proximity switch 35 is fixedly installed at a position corresponding to the primary positioning block 29 on the chain plate conveyor 30, and a secondary positioning block 34 is fixedly provided at the front end of the chain plate conveyor 30. The secondary positioning block 24 is a right-angle L-shaped structure, and a secondary proximity switch 33 is fixedly installed in front of the secondary positioning block 34.

[0047] like Fig.11 , 12 As shown in Figures 1 and 13, the laser angle cutting machine 38 is movably mounted on the three-axis truss 37, and can perform three-dimensional movement on the three-axis truss 37 in the X-axis, Y-axis and Z-axis directions to cut the angle steel on the transverse conveying mechanism 6. The X-axis bracket is arranged parallel to the length direction of the feeding channel 2, and one end of a pair of Y-axis brackets 45 is slidably mounted on both ends of the X-axis bracket through guide rails. The X-axis displacement device 39 is fixedly mounted on the end of the Y-axis bracket 45, and the X-axis displacement device 39 is used to drive the Y-axis bracket 45 to move horizontally along the X-axis bracket. The upper side surface of the fixed plate 41 is slidably mounted on the Y-axis bracket 45 through guide rails, and the Y-axis displacement device 44 is fixedly mounted above the fixed plate 41, and the Y-axis displacement device 44 is used to drive the fixed plate 41 to move horizontally along the Y-axis bracket 45. The Z-axis bracket 43 is slidably mounted on the fixed plate 41 through a guide rail, the Z-axis displacement device 42 is fixedly mounted on a side of the fixed plate 41, the swing motor 40 is fixedly mounted on the lower end of the Z-axis bracket 43, and the laser angle cutter 38 is fixedly mounted on the end of the swing shaft of the swing motor 40. The swing motor 40 controls the swing of the laser angle cutter 38, and the two surfaces of the angle steel end can be cut from two directions respectively, which can reduce cutting slag. The X-axis displacement device 39, the Y-axis displacement device 44 and the Z-axis displacement device 42 are existing technologies, and can be moved by a structure in which gears and racks cooperate.

[0048] The angle steel intelligent double-end laser angle cutting processing method uses the aforementioned angle steel intelligent double-end laser angle cutting processing system, and includes the following steps:

[0049] Step 1: The pressing and conveying mechanism 4 conveys the angle steel to the feeding channel 2.

[0050] After the angle steel is processed in the previous process, the right end of the angle steel is placed on the left end of the cylindrical roller group 18. The machine in the previous process provides thrust to push the right end of the angle steel to the bottom of the pressing roller 10. The first proximity switch sends a signal to the upper computer, and the upper computer controls the start of the second adjustment cylinder 19 to lower the pressing roller 10. The distance between the pressing roller 10 and the cylindrical roller group 18 is slightly smaller than the thickness of the angle steel, completing the compression of the angle steel. The upper computer controls the start of the reduction motor 12, and the pressing roller 10 rotates through the chain transmission assembly 20, driving the angle steel to feed to the right. The position sensor detects that there is an incoming angle steel, and the position sensor sends a signal to the upper computer. The upper computer controls the press cylinder 14 to start, and the push rod of the press cylinder 14 drives the connecting rod 15 to rotate. The connecting rod 15 rotates to move the damping wheel 16 downward, and the angle steel is pressed by the downwardly moved damping wheel 16 to assist in pressing. After the first photoelectric sensor detects that the angle steel has completely passed through the push claw 21, the right end of the push claw 21 is lifted due to the weight of the left end, and the right end of the push claw 21 abuts against the left end of the angle steel. The first photoelectric sensor sends a signal to the upper computer, and the upper computer controls the push motor 17 to start, and the push claw 21 moves to the right through the lead screw drive, and the angle steel is pushed above the feeding channel 2 as a whole. The second proximity switch detects that the left end of the angle steel has left the frame 5, and the second proximity switch sends a signal to the upper computer, and the upper computer controls the push motor 17 to reverse to reset the push claw 21, and the upper computer controls the press cylinder 14 to move in the opposite direction to reset the press cylinder 17.

[0051] Step 2: The turning mechanism 1 turns the positive V-shaped angle steel into an inverted V-shape and places it on the transverse conveying mechanism 6.

[0052] After receiving the signal sent by the second proximity switch, the host computer controls the flip motor 26 to start, and the second photoelectric sensor 28 sends a detection signal to the host computer after scanning the detection hole 27, and the host computer controls the flip motor 26 to pause intermittently; when the host computer does not receive the second proximity switch signal, the flip motor 26 is controlled not to start. The flip motor 26 starts, and the flip motor 26 drives the motor reducer 25 to rotate, and the motor reducer 25 drives the flip shaft 24 and the equally divided circular disc 22 to rotate. The angle steel grabbing and placing notches on the equally divided circular disc 22 can automatically grab the positive V-shaped angle steel on the feeding channel 2. After the equally divided circular disc 22 rotates about half a circle, the first angle steel received by the equally divided circular disc 22 slides onto the transverse conveying mechanism 6. At this time, the sliding angle steel is in an inverted V shape, which automatically completes the flipping of the angle steel from the positive V shape to the inverted V shape, and then the inverted V-shaped angle steel is cut. The equally divided circular disc 22 performs intermittent circular motion, and the host computer controls the flip motor 26 to rotate one eighth of the circle each time.

[0053] Step 3: The transverse conveying mechanism 6 conveys the inverted V-shaped angle steel forward and stops conveying the angle steel at an appropriate position to wait for the angle cutting operation.

[0054] After the primary proximity switch 35 detects that an angle steel is coming in front, it sends a signal to the upper computer, and the upper computer controls the block cylinder 36 to move so that the primary positioning block 29 is raised above the upper surface of the chain plate conveyor 30; after the primary proximity switch 35 detects that the angle steel is blocked by the primary positioning block 29 for a certain period of time (blocking the angle steel for a certain period of time can ensure that the angle steel is completely close to the primary positioning block 29), it sends a signal to the upper computer, and the upper control machine controls the laser cutting mechanism 3 to cut the angle steel. After the cutting is completed, the upper computer controls the block cylinder 36 to reset the primary positioning block 29. The secondary positioning block 34 at the front end of the chain plate conveyor 30 is used to block the angle steel after cutting. After the secondary proximity switch 33 detects that the angle steel is blocked by the secondary positioning block 34 for a certain period of time, it sends a signal to the upper computer, and the upper computer controls other devices to unload the angle steel after cutting.

[0055] Step 4: The laser angle cutting mechanism 3 is used to perform angle cutting operations on angle steels.

[0056] The host computer controls the X-axis displacement device 39, the Y-axis displacement device 44 and the Z-axis displacement device 42 to start working, so that the laser angle cutter 38 at both ends of the three-axis truss 37 moves three-dimensionally until it accurately reaches the top of both ends of the angle steel. The host computer controls the swing motor 40 to start working, and the swing shaft of the swing motor 40 controls the laser angle cutter 38 to swing forward and backward. The laser angle cutter 38 swings forward 45 degrees and backward 45 degrees, and the angle steel is bent, which is convenient for cutting both sides of the angle steel.
