Description

Technical Field

[0001] The present application relates to the technical field of steel bar processing, and in particular to a steel bar cutting mechanism for an automatic steel bar processing production line. Background Art

[0002] Rebar processing occupies an important position in construction projects. With the continuous expansion of the scale of modern projects and technological advancement, rebar processing operations are gradually developing towards mechanization and automation.

[0003] The current mainstream steel bar processing equipment is mostly focused on the realization of single functions, such as separate steel bar bending machines, cutting machines, etc., but these devices often operate independently, and there are obvious deficiencies in integration and efficiency. In recent years, fully automatic steel bar processing production lines have become an important trend in the development of the industry. The production line integrates multiple links such as steel bar stretching, cutting, and coiling. The steel bar cutting equipment is used to shear the steel bar after the stretching is completed. Subsequently, the cut steel bar is coiled. The steel bar cutting operation is a part of the production line. The production line needs to produce materials without stopping. When the position where the steel bar needs to be cut is transported to the cutting mechanism, the hydraulic cylinder drives the cutting knife to cut the cutting point of the steel bar. One end is coiled to complete the processing operation, and the other end continues to transport. However, when the steel bar cannot be cut or the cutting speed is slow, the steel bar will not stop being transported, and the arch steel phenomenon is prone to occur, causing the production line to stop, thereby making the steel bar processing efficiency low. Summary of the Invention

[0004] In order to reduce the possibility of steel bar arching and improve the processing efficiency of steel bars, the present application provides a steel bar tangent mechanism for an automatic steel bar processing production line.

[0005] This application provides a steel bar tangent mechanism for an automatic steel bar processing production line, which adopts the following technical solution:

[0006] A steel bar cutting mechanism for an automatic steel bar processing production line, comprising:

[0007] a frame connected to a first driving member;

[0008] A connecting seat is connected to the frame, and the connecting seat is connected to a guide assembly for guiding the movement of the steel bars;

[0009] The movable seat slides with the frame, the moving direction of the movable seat is parallel to the conveying direction of the steel bars, the movable seat is slidingly provided with a cutting knife, and the first driving member is used to drive the cutting knife to cut the steel bars;

[0010] The clamping assembly is arranged on the movable seat and is used for clamping the steel bars when cutting.

[0011] By adopting the above technical solution, the steel bar is inserted into the guide assembly, and the steel bar moves from the top of the movable seat. When the steel bar needs to be cut, the place where the steel bar needs to be cut is moved to the clamping assembly, and the clamping assembly is started to firmly clamp the steel bar. After the steel bar is clamped, the movable seat drives the clamping assembly to move synchronously with the steel bar, so that the movable seat, the clamping assembly and the steel bar are in a stationary state, and the first driving member is started, and the first driving member drives the cutting knife to cut the steel bar. By setting the clamping assembly, the steel bar will not move due to external force during the cutting process, thereby improving the shearing force and speed of the shearing knife, reducing the possibility of the steel bar not being cut or cutting slowly, thereby reducing the possibility of inaccurate cutting or arching of the steel bar during the cutting process, and improving the processing efficiency of the steel bar.

[0012] Optionally, the movable seat is located between the connecting seat and the frame, the connecting seat includes a fixed frame, a fixed plate, a baffle and a locking piece, the fixed frame is connected to the frame, the fixed plate is connected to the fixed frame, the fixed plates are symmetrically arranged at the top and bottom of the baffle, and the baffle is fixed to the fixed plate by a locking piece.

[0013] By adopting the above technical solution, when the movable seat or the clamping assembly is damaged, the baffle plate can be disassembled from the fixed plate through the locking piece, which facilitates the repair or replacement of the internal structure such as the movable seat or the clamping assembly, thereby improving convenience.

[0014] Optionally, the fixed plate is L-shaped, one side of the baffle plate is in contact with the side of the fixed frame away from the frame, the side of the baffle plate away from the fixed frame is in contact with the fixed plate, and the top wall and bottom wall of the baffle plate are respectively in contact with the two fixed plates.

[0015] By adopting the above technical solution, the baffle is positioned, reducing the possibility of the guide assembly installation position being offset due to the baffle position offset, thereby improving the accuracy of the steel bar conveying direction.

[0016] Optionally, the guide assembly includes a guide cylinder, which is provided with a guide hole, the diameter of the guide hole is larger than the diameter of the steel bar, and the guide cylinder is connected to the connecting seat.

[0017] By adopting the above technical solution, the steel bars are inserted into the guide holes, and the steel bars slide along the bottom wall of the guide holes to support the steel bars, thereby reducing the possibility of slow transportation efficiency caused by deformation of the steel bars. The diameter of the guide holes is set to be larger than the diameter of the steel bars to reduce friction, thereby improving the accuracy of the steel bar transportation speed and reducing the possibility of arching steel.

[0018] Optionally, one end of the guide cylinder away from the connecting seat is connected to a guide member, the guide member is trumpet-shaped, and the inner wall of the guide member is rotatably connected to a guide roller, and the guide roller is convex in the middle.

[0019] By adopting the above technical solution, when the steel bars are transported, the steel bars are located at the top bulge of the guide roller. When the steel bars are sheared, the shearing knife has a pushing force on the steel bars, causing the steel bars to pause briefly. However, the transportation of the steel bars as a whole does not stop at this time. The steel bars are blocked by the shearing knife, which may easily lead to the possibility of arching of the steel bars. A bulge is set in the middle of the guide roller, and the two ends of the guide roller are concave. When the steel bars are blocked, the guide roller guides the steel bars so that the steel bars move toward the two ends, providing a deformation range of the breaking stroke for the steel bars, thereby reducing the possibility of shutdown caused by arching of the steel bars.

[0020] Optionally, the clamping assembly is slidably connected to the movable seat, the clamping assembly is connected to a first elastic member, and the first elastic member is connected to the movable seat.

[0021] By adopting the above technical solution, at the moment of shearing the steel bar, the movable seat continues to move, and the first elastic member is provided, which can quickly reset the clamping assembly and pull the steel bar at the same time, so that the slightly deformed parts of the steel bar can be quickly restored, further reducing the possibility of arching steel and improving processing efficiency.

[0022] Optionally, a controller is provided on one side of the frame, and a mounting plate is connected to one side of the frame. The mounting plate is connected to a half-cut sensor and a full-cut sensor. The half-cut sensor is used to sense when the steel bar is cut to the center of the steel bar, and transmits a signal to the controller. The controller controls the output end of the first drive member to be away from the steel bar; the full-cut sensor is used to sense when the steel bar is cut to the point where the steel bar is cut, and transmits a signal to the controller. The controller controls the output end of the first drive member to be away from the steel bar.

[0023] By adopting the above technical solution, a half-cut sensor and a full-cut sensor are set up, so that the steel bars are cut at least twice. The steel bars are cut through multiple cutting and rapid cutting, reducing the possibility of the cutting knife continuously blocking the steel bar transportation and causing arched steel, thereby improving the processing efficiency of the steel bars.

[0024] Optionally, a placement plate is connected to the bottom of the rack, a top wall of the placement plate is connected to a reinforcing rib, and the reinforcing rib is connected to the rack.

[0025] By adopting the above technical solution, the placement plate provides a placement basis for the frame, so that the frame is stably placed on the ground. Reinforcing ribs are provided to support the frame, reducing the possibility of the frame tipping over under the strong drive of the first driving member, thereby improving the cutting stability.

[0026] Optionally, the cutting knife is connected to a fourth elastic member, the end of the fourth elastic member away from the cutting knife is connected to the clamping assembly, the cutting knife is slidably connected to the clamping assembly, a push plate is provided at the end of the cutting knife away from the clamping assembly, and the output end of the first driving member is connected to the push plate.

[0027] By adopting the above technical solution, the cutting knife moves synchronously with the clamping assembly, the first driving member drives the pushing plate to move, and the pushing plate then pushes the cutting knife to cut the steel bar, so that the clamping assembly moves stably and smoothly, and the steel bar can be cut multiple times at the same time, thereby improving the cutting efficiency.

[0028] Optionally, the frame is connected to a second driving member, the movable seat is threadedly connected to a transmission screw, the output end of the second driving member is connected to the transmission screw, and the end of the transmission screw away from the second driving member is rotatably connected to the frame.

[0029] By adopting the above technical solution, the second driving member is started, and the second driving member drives the transmission screw to rotate, and the rotation of the transmission screw drives the moving seat to move, thereby adjusting the moving speed of the moving seat to a constant speed, so that the moving speed of the moving seat is consistent with the conveying speed of the steel bars, and there is no need to drive the moving seat to move by the steel bars, further reducing the possibility of steel bars feeding during shearing, thereby improving the processing efficiency of the steel bars.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The steel bar is inserted into the guide assembly, and the steel bar moves from the top of the moving seat. When the steel bar needs to be cut, the place where the steel bar needs to be cut moves to the clamping assembly, and the clamping assembly is started to firmly clamp the steel bar. After the steel bar is clamped, the moving seat drives the clamping assembly to move synchronously with the steel bar, so that the moving seat, the clamping assembly and the steel bar are in a stationary state, and the first driving member is started. The first driving member drives the cutting knife to cut the steel bar. By setting the clamping assembly, the steel bar will not move due to external force during the cutting process, thereby improving the shearing force and speed of the shearing knife, reducing the possibility of the steel bar not being cut or the cutting speed being slow, thereby reducing the possibility of inaccurate cutting or the arching of the steel bar during the cutting process, and improving the processing efficiency of the steel bar;

[0032] 2. When the steel bar is being transported, the steel bar is located at the top bulge of the guide roller. When the steel bar is sheared, the shear knife pushes the steel bar, causing the steel bar to pause briefly. However, the steel bar as a whole does not stop being transported at this time. The steel bar is blocked by the shear knife, which may easily lead to the possibility of steel arching. The middle part of the guide roller is convex, and the two ends of the guide roller are concave. When the steel bar is blocked, the guide roller guides the steel bar, causing the steel bar to move toward the two ends, providing a deformation range for the steel bar to break the stroke, reducing the possibility of steel arching causing shutdown;

[0033] 3. At the moment of shearing the steel bar, the moving seat continues to move, and the first elastic member is provided to quickly reset the clamping assembly and pull the steel bar at the same time, so that the slightly deformed part of the steel bar can be quickly restored, further reducing the possibility of arching steel and improving processing efficiency.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] The embodiment of the present application discloses a steel bar cutting mechanism for an automatic steel bar processing production line.

[0044] Reference Figure 1 and Figure 2A steel bar cutting mechanism for an automatic steel bar processing production line includes a frame 1, a connecting seat, a moving seat 3 and a clamping assembly 4. A mounting groove is opened on one side of the frame 1. The groove wall of the mounting groove away from the groove is fixedly connected to a first driving member 12. The connecting seat is fixedly connected to the side of the frame 1 close to the mounting groove. The side of the connecting seat away from the frame 1 is fixedly connected to a guide assembly. The guide assembly is used to guide the movement of the steel bar. The moving seat 3 slides with the frame 1. The moving direction of the moving seat 3 is parallel to the conveying direction of the steel bar. The frame 1 is close to the mounting groove. A conveying groove is provided on one side of the connecting seat, and the connecting seat is blocked by the conveying groove. The bottom wall of the conveying groove is fixedly connected to a conveying guide rail 13. The movable seat 3 slides along the conveying guide rail 13. The conveying guide rail 13 guides the moving direction of the movable seat 3. The movable seat 3 is slidingly provided with a cutting knife 121. The first driving member 12 is used to drive the cutting knife 121 to cut the steel bars. The clamping assembly 4 is provided at the top of the movable seat 3. The clamping assembly 4 is used to clamp the steel bars when cutting. In this embodiment, the first driving member 12 adopts a driving motor.

[0045] When the steel bar is in the production line, the steel bar is inserted into the guide assembly, and the steel bar moves from the top of the movable seat 3. When the steel bar needs to be cut, the place where the steel bar needs to be cut is moved to the clamping assembly 4, and the clamping assembly 4 is started to firmly clamp the steel bar. After the steel bar is clamped, the movable seat 3 drives the clamping assembly 4 to move synchronously with the steel bar, so that the movable seat 3, the clamping assembly 4 and the steel bar are in a stationary state, and the first driving member 12 is started. The first driving member 12 drives the cutting knife 121 to cut the steel bar. By setting the clamping assembly 4, the steel bar will not move due to external force during the cutting process, thereby improving the shearing force and speed of the shearing knife, reducing the possibility of the steel bar not being cut or the cutting speed being slow, thereby reducing the possibility of inaccurate cutting or the arching of the steel bar during the cutting process, and improving the processing efficiency of the steel bar.

[0046] The bottom wall of the frame 1 is fixedly connected to a placement plate 11, and the top wall of the placement plate 11 is fixedly connected to a reinforcing rib 14. One side of the reinforcing rib 14 is fixedly connected to one side of the frame 1. The reinforcing rib 14 is evenly distributed along the outer wall of the frame 1 to enhance the stability of the frame 1.

[0047] The movable seat 3 is located between the connecting seat and the frame 1. The connecting seat includes a fixed frame 2, a fixed plate 21, a baffle plate 22 and a locking member 23. One side of the fixed frame 2 is fixedly connected to the side of the frame 1 close to the mounting groove, and one side of the fixed plate 21 is fixedly connected to the side of the fixed frame 2 away from the fixed frame 2. The fixed plate 21 is symmetrically arranged at the top and bottom of the baffle plate 22. The baffle plate 22 is provided with a through hole, and the fixed plate 21 is provided with a threaded groove. The locking member 23 is inserted into the through hole, and the head of the locking member 23 is tightly against the fixed plate 21. The tail of the locking member 23 matches the thread of the threaded groove, so that the locking member 23 is threadedly connected to the fixed plate 21. In this embodiment, the locking member 23 adopts a bolt, and the baffle plate 22 is fixed to the fixed plate 21 through the locking member 23, so that the baffle plate 22 blocks the conveying trough.

[0048] The fixing plate 21 is L-shaped, and one side of the baffle plate 22 is in contact with the side of the fixing frame 2 away from the frame 1, and the side of the baffle plate 22 away from the fixing frame 2 is in contact with the fixing plate 21, and the top wall and bottom wall of the baffle plate 22 are respectively in contact with the two fixing plates 21, thereby positioning the baffle plate 22 and facilitating the installation of the baffle plate 22.

[0049] A through groove is provided on one side of the baffle plate 22 close to the fixed plate 21, and the guide assembly includes a guide cylinder 5, which is provided with a guide hole. The guide hole is connected to the through groove, and the diameter of the guide hole is larger than the diameter of the steel bar. One side of the guide cylinder 5 is fixedly connected to the side of the baffle plate 22 where the through groove is provided.

[0050] A guide member 51 is fixedly connected to the side of the guide cylinder 5 away from the baffle 22. The guide member 51 is in the shape of a trumpet, and the end of the guide member 51 with a smaller trumpet opening is fixed to the guide cylinder 5 around the guide hole. The guide member 51 is rotatably connected to the inner wall of the side away from the guide cylinder 5. The length direction of the rotating axis of the guide roller 52 is perpendicular to the direction of steel bar transportation. The guide roller 52 is convex in the middle, and the height of the convex top wall of the guide roller 52 is not lower than the height of the bottom wall of the guide hole, and the height distance is 0cm to 5cm. When the guide roller 52 supports the steel bar, the bottom wall of the guide hole can also support the steel bar. When the steel bar is deformed, the guide roller 52 guides the steel bar so that the steel bar is slightly deformed toward the concave parts at both ends of the guide roller 52, providing a buffer space for the normal transportation of the steel bar.

[0051] Reference Figure 2 and Figure 3 A second driving member 31 is fixedly connected to the side of the frame 1 away from the fixed frame 2, and the movable seat 3 is threadedly connected to a transmission screw 32. The output end of the second driving member 31 is connected to one end of the transmission screw 32, and the end of the transmission screw 32 away from the second driving member 31 is rotatably connected to the frame 1. In this embodiment, the second driving member 31 adopts a driving motor.

[0052] When the movable base 3 is driven to move, the second driving member 31 is started, and the second driving member 31 drives the transmission screw 32 to rotate. Under the guidance of the conveying guide rail 13, the movable base 3 is driven to move in a directional manner, thereby facilitating the adjustment of the moving speed of the movable base 3.

[0053] The end of the clamping assembly 4 away from the fixed frame 2 is slidingly connected to the sliding rod 33, the sliding direction of the sliding rod 33 is parallel to the moving direction of the moving seat 3, the end of the sliding rod 33 away from the clamping assembly 4 is fixedly connected to the moving seat 3, the clamping assembly 4 is slidingly connected to the moving seat 3 through the sliding rod 33, one side of the clamping assembly 4 is fixedly connected to the first elastic member 34, the end of the first elastic member 34 away from the clamping assembly 4 is fixedly connected to the end of the moving seat 3 close to the sliding rod 33, the first elastic member 34 is sleeved on the sliding rod 33, and in this example, the first elastic member 34 is a spring.

[0054] Reference Figure 3 and Figure 4 The clamping assembly 4 includes a first clamping member 41, a second clamping member 42, a sliding column 43, a limit member 44, a second elastic member 45, a sliding plate 46, an unlocking member and a locking member. The first clamping member 41 is in contact with the wall of the conveying trough. The end of the first clamping member 41 away from the fixed frame 2 is slidably connected to the sliding rod 33, thereby guiding the sliding direction of the first clamping member 41 on the movable seat 3. The end of the first clamping member 41 away from the fixed frame 2 is provided with an unlocking groove. 413, the unlocking groove 413 is square, and the height of the unlocking groove 413 is equal to the diameter of the sliding column 43, so that the sliding column 43 can slide directionally in the unlocking groove 413, and the end of the sliding column 43 away from the unlocking groove 413 is fixedly connected to the side of the second clamping member 42 away from the fixed frame 2. The second clamping member 42 is slidably connected to the first clamping member 41 through the sliding rod 33, and the sliding direction of the second clamping member 42 is perpendicular to the moving direction of the movable seat 3. The top of the limit piece 44 is inserted into the unlocking groove 413, and the bottom of the limit piece 44 is slidingly connected to the first clamping piece 41, and the limit piece 44 is fixedly connected to one end of the second elastic piece 45, and the end of the second elastic piece 45 away from the limit piece 44 is fixedly connected to the top wall of the sliding plate 46, and the sliding plate 46 is vertically slidingly connected to the limit piece 44. A sliding groove is provided on the side of the moving seat 3 away from the fixed frame 2, and the sliding plate 46 is slidingly connected to the groove wall of the sliding groove, and the sliding direction of the sliding plate 46 is parallel to the moving direction of the moving seat 3. The unlocking component is located at the end of the moving seat 3 away from the fixed frame 2. The unlocking component is used to release the clamping state of the first clamping piece 41 and the second clamping piece 42 to release the clamping state of the steel bar after cutting is completed. The locking component is located at the end of the moving seat 3 close to the fixed frame 2, and the locking component is used to clamp the first clamping piece 41 and the second clamping piece 42 to clamp the steel bar to be cut. In this embodiment, the second elastic piece 45 adopts a spring.

[0055] Reference Figure 3 and Figure 5 The unlocking component includes a third elastic member 47, an unlocking member 471, a hinge seat 472, a hinge plate 473, a torsion spring 474 and a pushing member 475. One end of the third elastic member 47 is fixedly connected to the first clamping member 41, and the end of the third elastic member 47 away from the first clamping member 41 is connected to the second clamping member 42. When the third elastic member 47 is stationary, the third elastic member 47 is always in a stretched state, and one end of the unlocking member 471 is fixedly connected to the bottom side of the limit member 44. The unlocking member 471 is located just below the second elastic member 45, and the end of the unlocking member 471 away from the limit member 44 is toward the second driving member 31. The unlocking member 471 is horizontally arranged, and the end away from the limit member 44 is dome-shaped. The end of the unlocking member 471 away from the limit member 44 is toward the second driving member 31. The hinge seat 472 is fixedly connected to the top wall of the conveying guide rail 13. The cam 473 is fixed to the cam 472 so that the cam 473 can be rotated to rotate relative to the cam 474.

[0056] When the steel bar cutting operation is completed, the moving seat 3 continues to drive the steel bar to move in the direction of the second driving member 31, and the unlocking member 471 contacts the bottom wall of the hinge plate 473. When the moving seat 3 continues to move, the unlocking member 471 moves on the inclined surface of the hinge plate 473, thereby causing the unlocking member 471 to move downward, thereby driving the limiting member 44 to move out of the unlocking groove 413, and the second driving member 31 drives the transmission screw 32 to rotate, and the transmission screw 32 rotates to drive the pushing member 475 to rotate, and the pushing member 475 pushes the sliding column 43 to slide in the direction away from the first clamping member 41, and the sliding column 43 moves to the side of the limiting member 44 away from the first clamping member 41, so that the first clamping member 41 and the second clamping member 42 is away from the steel bar, and the first clamping member 41 and the second clamping member 42 are in a released state. When the unlocking member 471 is separated from the hinge plate 473, the limiting member 44 is inserted into the unlocking groove 413 under the elastic action of the second elastic member 45. Then, the second driving member 31 is started, and the second driving member 31 drives the transmission screw 32 to rotate in the opposite direction, so that the movable seat 3 moves toward the direction close to the fixed frame 2. Under the contraction action of the third elastic member 47, the sliding column 43 is tightly against the limiting member 44, thereby positioning the positional relationship between the first clamping member 41 and the second clamping member 42, so that the first clamping member 41 and the second clamping member 42 can move to one end close to the fixed frame 2 without releasing the contact with the steel bar.

[0057] Reference Figure 6 The locking component includes a locking member 48 and a locking plate 481. The locking member 48 is fixedly connected to the side of the limit member 44 away from the unlocking member 471. The locking member 48 is arranged horizontally, and the end away from the limit member 44 is dome-shaped. One side of the locking plate 481 is fixedly connected to one side of the frame 1, and the locking plate 481 is located at the end of the transmission screw 32 away from the second driving member 31. The side of the locking plate 481 away from the frame 1 is inclined. The inclined side of the locking plate 481 is used to push the locking member 48 downward, so that the limit member 44 slides out of the unlocking groove 413.

[0058] After the first clamping member 41 and the second clamping member 42 are in the relaxed state, the steel bar is freely transported. At this time, the second driving member 31 is in the closed state, and the steel bar continues to slide between the first clamping member 41 and the second clamping member 42. When the steel bar needs to be sheared, the second driving member 31 is started, and the second driving member 31 drives the transmission screw to rotate in the opposite direction, so that the movable seat 3 moves toward the direction of the fixed frame 2. The movable seat 3 drives the locking member 48 to approach the locking plate 481, and the locking member 48 slides along the inclined surface of the locking plate 481. This causes the locking member 48 to move downward, thereby driving the limiting member 44 to slide out of the unlocking slot 413, and the third elastic member 47 contracts, causing the sliding column 43 to move quickly to the unlocking slot 413 close to one end of the first clamping member 41, thereby clamping the steel bar. At this time, the outer wall of the sliding column 43 fits into the groove wall of the unlocking slot 413 and the outer wall of the limiting member 44. Subsequently, the second driving member 31 drives forward, driving the wire transmission rod to rotate forward, so that the movable seat 3 moves in the direction away from the fixed frame 2.

[0059] The first clamping member 41 is rotatably connected to a plurality of first conveying rollers 411, and the first conveying rollers 411 are arranged equidistantly along the conveying direction of the movable seat 3. The second clamping member 42 is rotatably connected to a plurality of second conveying rollers 421, and the first conveying rollers 411 and the second conveying rollers 421 are symmetrically arranged on both sides of the conveying direction of the steel bars. The first conveying rollers 411 and the second conveying rollers 421 are both concave in the middle and convex at both ends. In this example, there are four first conveying rollers 411 and four second conveying rollers 421.

[0060] The cutting knife 121 is T-shaped, and the end of the cutting knife 121 away from the blade is fixedly connected to the fourth elastic member 49, and the end of the fourth elastic member 49 away from the cutting knife 121 is fixedly connected to the side of the second clamping member 42 away from the first clamping member 41. The cutting knife 121 is slidingly connected to the second clamping member 42 and is located between adjacent second conveying rollers 421. The end of the cutting knife 121 away from the second clamping member 42 is provided with a pushing plate 122, and the output end of the first driving member 12 is fixedly connected to the pushing plate 122. The end of the cutting knife 121 away from the pushing plate 122 is provided with a cutting table 412, which is fixedly connected to the first clamping member 41. The cutting table 412 is tangent to the concave point in the middle of the first conveying roller 411 away from the side close to the cutting knife 121. The cutting table 412 provides stable cutting support for the cutting knife 121. In this embodiment, the fourth elastic member 49 is a spring.

[0061] Reference Figure 1A control (not shown in the figure) is provided on one side of the frame 1 for controlling the operation of the equipment. A mounting plate 15 is fixedly connected to the groove wall of the mounting groove, and a half-cut sensor 16 and a full-cut sensor 17 are fixedly connected to the mounting plate 15. The half-cut sensor 16 is located at the end of the full-cut sensor 17 away from the push plate 122. The half-cut sensor 16 is used to sense when the steel bar is cut to the center of the steel bar, and transmit a signal to the controller. The controller controls the output end of the first driving member 12 to be away from the steel bar; the full-cut sensor 17 is used to sense when the steel bar is cut to the steel bar, and transmit a signal to the controller. The controller controls the output end of the first driving member 12 to be away from the steel bar. In this example, both the half-cut sensor 16 and the full-cut sensor 17 use displacement sensors.

[0062] When the steel bar is cut, the second driving member 31 drives the movable seat 3 to move in the direction of the fixed frame 2 until the locking member 48 slides along the inclined surface of the locking plate 481, causing the limit member 44 to slide out of the unlocking groove 413, and the third elastic member 47 contracts, causing the sliding column 43 to stick to the unlocking groove 413 near one end side of the first clamping member 41, and the first conveying roller 411 and the second conveying roller 421 clamp the steel bar. Then, the second driving member 31 drives the movable seat 3 to move in the direction away from the fixed member, so that the movable seat 3 drives the steel bar to move synchronously, and the first driving member 12 is started. The first driving member 12 drives the pushing plate 122 to move rapidly toward the cutting knife 121, and the pushing plate 122 pushes the cutting knife 121, so that The cutting knife 121 cuts the steel bar quickly, and the half-cut sensor 16 senses when the steel bar is cut to the center of the steel bar and transmits a signal to the controller. The controller controls the output end of the first driving member 12 to move away from the steel bar, thereby completing one cutting. Subsequently, the first driving member 12 drives the pushing plate 122 again to push the cutting knife 121 to move, so that the cutting knife 121 cuts the steel bar again. The full-cut sensor 17 senses when the steel bar is cut to the point where the steel bar is cut, and transmits a signal to the controller. The controller controls the output end of the first driving member 12 to move away from the steel bar, thereby completing the cutting operation on the steel bar. The moving seat 3 continues to move until the unlocking member 471 slides downward along the hinged plate 473, and the pushing member 475 pushes the sliding column 43 to the end of the limiting member 44 away from the first clamping member 41, thereby releasing the steel bar and allowing the steel bar to be freely transported, reducing the possibility of the steel bar not being cut or the cutting speed being slow, thereby reducing the possibility of inaccurate cutting or the arching of the steel bar during the cutting process, and improving the processing efficiency of the steel bar.

[0063] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and do not limit the scope of protection of the present application in turn. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
