DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 9As shown, the embodiment of the utility model provides a multi-saw linkage steel bar fixed length sawing machine device, including a reversible steel bar discharge mechanism 1 for placing steel bars to be sawed, a lifting and flipping mechanism 2 for picking up steel bars, a ring-shaped steel bar conveying line for conveying steel bars in a ring direction, and a servo fixed length component for positioning the length of steel bars. Preferably, the ring-shaped steel bar conveying line includes a plurality of steel bar conveying mechanisms arranged in parallel on the side of the lifting and flipping mechanism 2 away from the steel bar discharge mechanism 1 and distributed in a rectangular shape. In this embodiment, there are four conveying lines, namely, a first steel bar conveying mechanism 41, a second steel bar conveying mechanism 42, a third steel bar conveying mechanism 43, and a fourth steel bar conveying mechanism 44, which are distributed in a matrix. The second steel bar conveying mechanism 42 is arranged at the end of the first steel bar conveying mechanism 41 along the steel bar conveying direction, the third steel bar conveying mechanism 43 is arranged at the side of the second steel bar conveying mechanism 42 and is parallel to the second steel bar conveying mechanism 42, and the fourth steel bar conveying mechanism 44 is arranged at the side of the first steel bar conveying mechanism 41 and is parallel to the first steel bar conveying mechanism 41, and is also connected to the third steel bar conveying mechanism 43.

[0035] Furthermore, a first electric saw 31 for sawing the head of the steel bar is installed in a liftable manner at the end of the lifting and flipping mechanism 2 and the first steel bar conveying mechanism 41, and a second electric saw 32 for sawing the middle and tail of the steel bar is installed between the first steel bar conveying mechanism 41 and the second steel bar conveying mechanism 42, and the second electric saw 32 is provided with two groups.

[0036] Furthermore, if Figure 4 3 is a schematic diagram of the structure of the second electric saw 32 in this embodiment. Specifically, a first electric saw bracket 321 is installed between the first steel bar conveying mechanism 41 and the second steel bar conveying mechanism 42. The electric saw bracket 321 is installed with a guide rail 322 in the height direction. The second electric saw 32 is driven by a servo electric cylinder 323 to slide on the guide rail 322. A clamping claw module 324 for clamping steel bars is installed at the bottom of the electric saw bracket 321 below the second electric saw 321. Two sets of clamping claw modules 324 are provided below each second electric saw 32. The clamping claw module 324 includes a plurality of clamping claw modules 324, each of which includes a plurality of clamping claw modules 324. The clamping base 3241 is arranged below the second electric saw 32, and two clamping plates 3243 are installed on the clamping base 3241 and can be moved in the same or opposite directions at the same time by the clamping driving member 3242 to clamp or loosen the steel bars. Optionally, the clamping driving member 3242 can be set as a cylinder and connected to the clamping plate 3243. The clamping plate 3243 is a sheet metal plate body, and a slot is provided on the side facing the steel bar. When working, the cylinder drives the sheet metal plate body to move toward the direction close to the steel bar, and the steel bar is clamped into the slot to achieve the clamping effect. It should be noted that the structure of the first electric saw 31 in this embodiment is the same as that of the second electric saw 32, so it is not repeated.

[0037] See also Figure 1 , Figure 7 and Figure 8 As shown, the lifting and turning mechanism 2 includes a plurality of lifting frames 201 which are spaced apart from each other between the steel bar discharging mechanism 1 and the first steel bar conveying mechanism 41, and a lifting trough 203 which is driven by a lifting motor 202 and can be lifted and lowered on the plurality of lifting frames 201. The plurality of lifting frames 201 are inclinedly installed with guide plates 204 at the top along the height direction for lifting the steel bars through the lifting trough 203 and then sliding them to the first steel bar conveying mechanism 41.

[0038] Furthermore, a lifting shaft 205 is rotatably mounted on the top of the lifting bracket 201, a first rotating gear 506 is coaxially connected to the lifting shaft 5, and a second rotating gear ( Figure 7 201 ), and the first rotating gear 506 and the second rotating gear are connected by a meshing chain 207. It should be noted that in this embodiment, the steel bar is turned to the lifting trough 203 by the steel bar discharging mechanism 1. After the first electric saw 31 works to cut the end of the steel bar, the lifting trough 203 is driven by the lifting motor 202 and is lifted to the top of the lifting bracket 201 by the mutual cooperation of the first rotating gear 506, the second rotating gear and the chain 207. After reaching the position, the steel bar slides along the guide plate 204 to the first steel bar conveying mechanism 41.

[0039] See also Figure 1 and Figure 5 As shown, the steel bar conveying mechanism 42 is installed on the supporting base frame 6. Taking the second steel bar conveying mechanism 42 as an example, the steel bar conveying mechanism includes a steel bar conveying trough 421 arranged along the conveying direction of the steel bars and a plurality of rollers 422 arranged at intervals at the bottom of the steel bar conveying trough 421. The steel bars are movably placed in the steel bar conveying trough 421, and the steel bar conveying trough 421 is installed with a turning shaft 423 at the edge of one side away from the lifting and turning mechanism 2 along the axial direction of the steel bar conveying trough 421 through a driving device 424. The turning shaft 423 is supported by a support bearing 425. It should be noted that the steel bars are conveyed by the friction force generated by the rolling of the roller 422, and after being conveyed to the fixed-length adjustment mechanism 52 and cut by the second electric saw 32, the turning shaft 423 is rotated to drive the steel bar conveying trough 421 to turn the steel bars to the adjacent steel bar conveying mechanism. In this embodiment, the first steel bar conveying mechanism 41, the third steel bar conveying mechanism 43 and the fourth steel bar conveying mechanism 44 have the same structure as the second steel bar conveying mechanism 42, so they are not repeated here.

[0040] Furthermore, in this embodiment, the driving device 424 can adopt a high-power motor, and one end of the flip shaft 423 is externally connected to the driving device 424. The flip shaft 423 is driven to rotate by the high-power motor. The flip shaft 423 drives the entire steel bar conveying trough 421 and the steel bars inside it to flip to one side with the flip shaft 423 as the axis, and the steel bars are poured out of the steel bar conveying trough 421, thereby facilitating the transportation of steel bars. The steel bar conveying trough 421 adopts a U-shaped groove that is wide at the top and narrow at the bottom. The inner wall of the U-shaped groove can cooperate with the inclined structure of the induction plate 551 in the steel bar sensing mechanism 55, and play a certain guiding role, so that the induction plate 551 can be accurately and stably inserted into the steel bar conveying trough 421, ensuring that the limiting position of the induction plate 551 on the steel bar accurately meets the fixed length requirements of the steel bar cutting. It should be noted that the main structure of the steel bar discharging mechanism 1 in this embodiment is the same as the structure of the steel bar conveying mechanism, both of which include a steel bar conveying trough for conveying steel bars, a roller for driving the steel bar conveying trough to work and convey steel bars, and a turning shaft for driving the steel bar conveying trough to turn the steel bars to the lifting trough 203 of the lifting and turning mechanism 2, and the end of the turning shaft is externally connected to a driving device, and the driving device can use a high-power motor, so it is not repeated here.

[0041] See also Figure 1 and Figure 6 As shown, in this embodiment, there are two groups of servo sizing components, namely, a servo sizing component 1 501 located directly above the first steel bar conveying mechanism 41 and the fourth steel bar conveying mechanism 44, and a servo sizing component 2 502 located directly above the second steel bar conveying mechanism 42 and the third steel bar conveying mechanism 43, and respectively used for positioning the middle and end parts of the steel bar when sawing. The servo sizing components include a linear guide rail 51 arranged in parallel above the plurality of steel bar conveying mechanisms, a fixed length adjustment mechanism slidably mounted on the linear guide rail 51 driven by a servo motor 522, and a servo sizing component 502 disposed on the linear guide rail 51. 52. A swing arm mechanism 53 swingably connected to the fixed-length adjustment mechanism 52, and a steel bar sensing mechanism 55 which is liftably installed on the swing arm mechanism 53 through a lifting mechanism 54 and is used to abut the steel bars placed on the steel bar conveying mechanism. It should be noted that through the setting of the fixed-length adjustment mechanism 52, the position of the steel bar sensing mechanism 55 on the steel bar conveying mechanism can be automatically adjusted according to the cutting length of the steel bars, so that when the steel bar conveying mechanism transports the steel bars to abut against the steel bar sensing mechanism 55, the steel bar sensing mechanism 55 is triggered to stop the transportation of the steel bars and perform the cutting operation, thereby improving the steel bar processing efficiency.

[0042] Furthermore, the fixed length adjustment mechanism 52 includes a motor base 521 slidably mounted on the linear guide rail 51 and interconnected with the servo motor 522, a reducer 523 mounted on the output end of the servo motor 522 and located at the bottom of the motor base 521, and a gear 524 coaxially connected to the output end of the reducer 523. A rack 525 is mounted on the side end surface of the linear guide rail 51, and the gear 524 is rollingly meshed with the rack 525. In this embodiment, the cooperation between the servo motor 522 and the reducer 523 can be used to adjust the speed of the gear 524, so as to ensure the stable linear motion of the motor base 521 along the linear guide rail 51. The gear 524 and the rack 525 are meshed and transmitted, so as to drive the motor base 5 to drive the steel bar sensing mechanism 55 to move forward or backward along the linear guide rail 51 to the positioning position required for steel bar cutting, so as to control the cutting accuracy.

[0043] Furthermore, the swing arm mechanism 53 includes a swing cylinder 531 slidably mounted on the bottom of the linear guide rail 51 through a mounting plate (not shown in the figure), and a swing arm 532 whose first end is swingably mounted on a side of the mounting plate (not shown in the figure) away from the swing cylinder 531 through a rotating seat (not shown in the figure), and whose second end is hinged to the telescopic end of the swing cylinder 531, and one end of the mounting seat away from the swing cylinder 531 is connected to the motor seat 521. The swing cylinder 531, the swing arm 532 and the mounting plate (not shown in the figure) form a triangular structure. Under the telescopic drive of the telescopic end of the swing cylinder 531, the swing arm 532 rotates around the rotating seat (not shown in the figure), changing the shape of the triangular structure, thereby realizing the swing of the swing arm 532 in the vertical plane, thereby driving the lifting mechanism 54 and the steel bar sensing mechanism 55 to rotate synchronously. Preferably, the lifting mechanism 54 includes a telescopic cylinder 541 installed on the swing arm 532 and a slide 542 installed on the telescopic cylinder 541. The steel bar sensing mechanism 55 is installed on the swing arm 532 so as to be liftable along the slide 542 through a slider, and the slider (not shown in the figure) is connected to the telescopic end of the telescopic cylinder 541.

[0044] like Figure 6 As shown, the steel bar sensing mechanism 55 includes a sensing plate 551 rotatably mounted on a slider (not shown in the figure) and a blocking plate 552 connected to the sensing plate 551 and used for the sensing plate 551 to be synchronously inserted into the steel bar conveying mechanism. It should be noted that in this embodiment, the sensing plate 551 is a sheet metal plate, and the fixed length adjustment mechanism 52 is driven by a servo motor 522 to accurately move and stop along the linear guide 51. The arm swing mechanism 53 and the lifting mechanism 54 are set to drive the steel bar sensing mechanism 55 to swing up and down and lift, so that the steel bar sensing mechanism 55 can be inserted downward into the steel bar conveying groove 421, which is convenient for positioning the steel bar conveying and cutting position, or moved upward out of the steel bar conveying groove 421, which is convenient for the steel bar sensing component to avoid the steel bar when the steel bar continues to be conveyed or transported, so as to ensure the continuous progress of the steel bar processing process.

[0045] See also Fig. 9 As shown, the working process of the utility model multi-saw linkage steel bar fixed length sawing machine device is as follows:

[0046] S1: The picked-up single steel bar 7 is sent from the steel bar discharging mechanism 1 to the direction of the first electric saw 31. After being transported to the right place, the steel bar 7 is flipped into the lifting groove of the lifting and flipping mechanism 2 and the end is pushed and positioned. The first electric saw 31 presses down to saw the head of the steel bar 7. After the sawing is completed, the lifting and flipping mechanism 2 lifts the steel bar 7 to the first steel bar conveying mechanism 41 through the lifting bracket.

[0047] S2: Move the servo sizing component 1 501 to the set position so that its baffle is at a sawing length from the second electric saw 32, and start the first steel bar conveying mechanism 41 to convey the steel bars toward the servo sizing component 2 502. When the end of the steel bar 7 reaches the baffle, the second electric saw 32 close to the first steel bar conveying mechanism 41 is pressed down for sawing.

[0048] S3: The steel bars 7 of the first steel bar conveying mechanism 41 are turned over to the fourth steel bar conveying mechanism 44 , and at the same time, the steel bars 7 of the second steel bar conveying mechanism 42 are turned over to the third steel bar conveying mechanism 43 .

[0049] S4: The steel bars 7 of the fourth steel bar conveying mechanism 44 are turned over to the following process, and the first steel bar conveying mechanism 41 receives the steel bars 7 of the second cycle.

[0050] S5: The servo-sizing component 1 501 and the servo-sizing component 2 502 move to the set position, and the steel bars of the third steel bar conveying mechanism 43 and the first steel bar conveying mechanism 41 are conveyed toward the baffle. After reaching the position, the two second electric saws 32 work simultaneously to cut the steel bars 7.

[0051] S6: The steel bars 7 of the fourth steel bar conveying mechanism 44 are turned over to the following process, and then the steel bars 7 on the third steel bar conveying mechanism 43 are sent to the fourth steel bar conveying mechanism 44.

[0052] S7: The steel bars 7 on the fourth steel bar conveying mechanism 44 are flipped to the next process. At this time, the first steel bar 7 has completed the cut-to-length sawing action, and then the steel bars 7 of the first steel bar conveying mechanism 41 are flipped to the fourth steel bar conveying mechanism 44. At the same time, the steel bars 7 of the second steel bar conveying mechanism 42 are flipped to the third steel bar conveying mechanism 43.

[0054] The multi-saw linkage steel bar fixed-length sawing machine device of the utility model is adopted to set up multiple saws, and the sequential cutting process is decomposed into several saws sawing at the same time, thereby shortening the overall time for cutting a raw material and improving the overall production rhythm. At the same time, the steel bar cutting optimization algorithm is used to carry out comprehensive steel bar cutting design for the processing data to form a sawing plan, which reduces the loss rate and has certain promotion value.
