Staggered steel bars are embedded in the concrete foundation to improve the strength of the foundation. According to actual needs, the ends of some steel bars need to be processed. During processing, the steel bars need to be fixed before subsequent processing can be carried out.

[0003] In the related art, a Chinese patent with publication number CN109290978A discloses a steel bar support frame for steel bar processing, the technical highlights of which are: it includes a base plate and a pressure plate, the top of the base plate is fixedly connected with an electric connecting rod, the top of the electric connecting rod is fixedly connected with a processing plate, the top of the pressure plate is fixedly connected with a motor, the rotating shaft of the motor extends to the inner cavity of the pressure plate and is fixedly connected with a large gear, the large gear is meshed with a small gear, both sides of the top of the processing plate are fixedly connected with pads, and grooves are provided on both sides of the bottom of the pressure plate and the top of the pad.

[0004] When the above device is used, two steel bars need to be placed in the grooves on the pad first, and then the motor is started, the motor drives the pressing plate to move down, clamps the steel bars on the pad, and then processes the ends of the steel bars; after the processing is completed, the motor drives the pressing plate to move up, and then the steel bars are taken out; then the next steel bar is put in, and the above process is repeated. When the number of steel bars to be processed is large, the operator needs to continuously move the steel bars, the work process is relatively cumbersome, the overall continuity is not strong, and it is easy to affect work efficiency. Summary of the invention

[0005] In order to improve the continuity of the steel bar processing process, the present application provides a support frame that is convenient for processing threaded steel bars.

[0006] The present application provides a support frame that facilitates the processing of threaded steel bars, which adopts the following technical solution:

[0007] A support frame for facilitating the processing of threaded steel bars, comprising:

[0008] A frame, the frame comprising a support plate and support legs arranged on the support plate;

[0009] A transfer mechanism, the transfer mechanism comprises a rotating power member, a rotating drum and a baffle frame, the rotating power member is fixedly arranged on a support plate, the rotating drum is rotatably arranged on the support plate, the rotating drum and the output end of the rotating power member are coaxially fixedly connected, an installation groove for placing steel bars is opened on the outer wall of the rotating drum along its own axial direction, a plurality of the installation grooves are arranged and arranged at intervals in a circle, the baffle frame is fixedly arranged on the support plate and surrounded by the outer side of the rotating drum, the two ends of the baffle frame are respectively the feeding side and the discharging side of the rotating drum, so that the steel bars entering the installation groove on the feeding side of the rotating drum can rotate with the rotating drum and then fall from the discharging side of the rotating drum;

[0010] A material dropping mechanism, used to make a steel bar in a pile of steel bars fall down; the material dropping mechanism comprises a charging box, a partition, a support block, a limit assembly and a driving assembly, the charging box is fixedly arranged on the support plate, the partition is arranged in the charging box, a plurality of the partitions are arranged and arranged in parallel and spaced apart, the partition divides the interior of the charging box into a plurality of accommodating cavities, the number of the support blocks is the same as the number of the accommodating cavities, each of the support blocks is vertically slidably arranged in one of the accommodating cavities, the limit assembly is arranged between the support block and the charging box, and is used to lock the support block after sliding upward in the current position, and the driving assembly is arranged on one side of the support block, and is used to drive the support block to slide upward;

[0011] A feeding mechanism is used to move the steel bars dropped by the dropping mechanism to the mounting groove on the feeding side of the rotating drum; the feeding mechanism comprises a first power telescopic member and a push plate, the first power telescopic member is fixedly arranged on the support plate, and the push plate is fixedly arranged on the movable end of the first power telescopic member;

[0012] A clamping mechanism for securing the steel bars dropped from the mounting slot on the discharge side of the drum;

[0013] The unloading mechanism is used to move the steel bars in the clamping mechanism to the outside of the support plate; the unloading mechanism includes a connecting rod and a push block, the connecting rod is fixedly arranged on the push plate, the push block is arranged at the end of the connecting rod, and the push block can be against the steel bars placed in the clamping mechanism.

[0014] By adopting the above technical scheme, a plurality of steel bars are installed in the top of the support block in each accommodating cavity along the vertical direction, and the driving component drives the support block to slide upward, and the support block can push the steel bars in the accommodating cavity to move upward, so that the topmost steel bar moves to the outside of the accommodating cavity, so that the topmost steel bar can fall from the top of the charging box after losing support, thereby realizing the dropping process of one steel bar, and the dropping mechanism can make one steel bar in the pile of steel bars fall down each time; then the loading mechanism moves the fallen steel bar to the installation groove on the feeding side of the rotating drum, and then the rotating power part drives the rotating drum to rotate, so that the steel bars in the installation groove rotate with it, until the installation groove rotates to the discharging side of the rotating drum, and then the steel bars in the installation groove fall down, and then clamped The mechanism can clamp and fix the steel bar, and then process the fixed steel bar. After the processing is completed, the steel bar is removed through the unloading mechanism, thereby automatically completing the loading, clamping and unloading processes of the steel bar; the operator only needs to put the steel bar into the unloading mechanism, so the continuity of the processing process is stronger; when the first power telescopic member drives the push plate to move, the push plate can drive the push block to move through the connecting rod, so that when the push plate pushes the steel bar into the mounting groove on the rotating drum, the push block can simultaneously push out the processed steel bar in the clamping mechanism, thereby completing the loading and unloading processes of the steel bar; both the unloading process and the loading process of the steel bar can be driven by the first power telescopic member, thereby reducing the required power source and being more energy-efficient.

[0015] Optionally, the end face of the top end of the charging box is inclined, and the top end of the support block is provided with an inclined surface, and the inclination direction of the inclined surface is the same as the inclination direction of the end face of the top end of the charging box.

[0016] By adopting the above technical solution, during the blanking process, the support block in the accommodating cavity at the lower end of the charging box is first moved upward. When the support block moves to the top of the charging box, the inclined surface on the top of the support block is parallel to the end surface of the top of the charging box. At this time, during the blanking process, the steel bars in the adjacent accommodating cavity can slide downward along the inclined surface on the support block at the top of the charging box after being ejected, and then fall. Therefore, the inclined surface on the top of the support block and the inclined setting of the top of the charging box both help the steel bars to fall smoothly after being ejected.

[0017] Optionally, the limiting assembly includes a limiting claw, a blocking claw and a first elastic member, the limiting claw is fixedly provided on the support block, the blocking claw is rotatably provided on the loading box, a plurality of blocking claws are provided and are arranged at intervals along the sliding direction of the support block, and the first elastic member is provided between the blocking claw and the loading box, so that when the support block moves upward, the blocking claw rotates to avoid, and when the support block has a tendency to move downward, the blocking claw is pressed against the limiting claw.

[0018] By adopting the above technical solution, the support block can be locked in the current position after moving upward, so the support block only needs to slide upward the same distance each time to drop a steel bar, which helps the steel bar dropping process to proceed smoothly.

[0019] Optionally, a holding rod is provided on one side of the blocking claw, and the holding rod is arranged along the sliding direction of the support block, and the holding rod and each of the blocking claws are rotationally connected.

[0020] By adopting the above technical solution, when all the steel bars in the charging box have fallen down, the charging box is in an empty state. At this time, each support block in the charging box is located at the top of the charging box. Through the holding rod, multiple claws in the vertical direction can be rotated synchronously, so that the claws are disengaged from the abutment with the limit claws. At this time, the support blocks can be moved downward to the bottom of the charging box, so as to facilitate the subsequent loading of new steel bars into the charging box.

[0021] Optionally, the driving assembly includes a driving rack, a driven rack, a driving gear, a driven gear, a transmission component and a locking piece, the driving rack is fixedly set on the push plate, the driven rack and the support block are detachably connected by a locking piece, the driving gear and the driven gear are both rotatably set on the support plate, the driving gear can mesh with the driving rack, the driven gear is meshed with the driven rack, and the transmission component is set between the driving gear and the driven gear, so that the driving gear can only drive the driven gear to rotate in one direction.

[0022] By adopting the above technical solution, the first power telescopic member enables the push plate to drive the active rack to slide when the push plate is reset. When the active rack is meshed with the active gear, the active rack drives the active gear to rotate. The active gear drives the driven gear to rotate in the same direction through the transmission component. The driven gear drives the driven rack to slide, and the driven rack drives the support block to move upward. That is, the support block can also be driven to move upward during the resetting process of the push plate. The movement of the support block does not require an additional power source, and is therefore more energy-efficient.

[0023] Optionally, a support plate is fixedly provided on the support plate, a mounting block is slidably provided on the support plate in a vertical direction, the driven rack is slidably provided on the mounting block in its own width direction, and a second elastic member is connected between the driven rack and the mounting block.

[0024] By adopting the above technical solution, under normal conditions, the second elastic member makes the driven rack and the driven gear in a meshing state. When the support block slides to the top of the charging box, the support block and the driven rack can be disassembled first, and then the driven rack can be slid to one side to disengage the driven rack from the meshing with the driven gear. At this time, the driven rack can be moved downward and then connected to another adjacent support block. When the driven rack moves downward, it will not drive the driven gear to rotate. Therefore, the downward movement of the driven rack will not cause the push plate to move, which is helpful for the push plate to work normally afterwards.

[0025] Optionally, the transmission component includes a ratchet, a pawl and a third elastic member, the ratchet is coaxially fixedly connected to the driving gear, the pawl is rotatably arranged on the driven gear, the third elastic member is connected between the pawl and the driven gear, and one end of the ratchet is against the pawl.

[0026] By adopting the above technical solution, the driving gear can drive the ratchet to rotate when it rotates. Since the ratchet pawl is pressed against the ratchet at this time, the rotation of the ratchet can drive the driven gear to rotate through the ratchet pawl; when the driving gear rotates in the opposite direction, the ratchet can rotate along with it, and the ratchet pawl can rotate to avoid it, so the rotation of the driving gear will not drive the driven gear to rotate; that is, the driving gear can only drive the driven gear to rotate in one direction, so when the push plate is reset, the driving gear can rotate forward, and the driven gear can rotate forward with it, and the driven rack moves up, thereby driving the support block to move up; when the push plate slides to the side close to the rotating drum, the driving gear can rotate in the opposite direction, and the driven gear and the driven rack both remain stationary, so the locking state of the support block can be maintained.

[0027] Optionally, a second power telescopic member is provided at the top of the charging box along its own inclination direction, and a sensor and a controller are provided at the top of the charging box, and the controller is electrically connected to the sensor and the second power telescopic member respectively.

[0028] By adopting the above technical solution, when the support block moves up and pushes the steel bars in the accommodating cavity to move upward, the topmost steel bar is outside the accommodating cavity. At this time, the sensor can detect the steel bar located outside the accommodating cavity, so that the controller can extend the movable end of the second power telescopic part to push the steel bar down, thereby preventing the steel bar located at the top of the loading box from staying on the loading box, which is conducive to the smooth progress of the subsequent steel bar processing process.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The operator only needs to put the steel bars into the loading box, and the dropping mechanism can automatically make the steel bars in the loading box fall down, and then the loading mechanism will move the steel bars to the installation slot on the feeding side of the drum, and then the drum will rotate to make the steel bars in the installation slot fall from the discharging side of the drum and fall into the clamping mechanism, and then the clamping mechanism will clamp and fix the steel bars to process them. After the processing is completed, the unloading mechanism will move the steel bars out to complete the processing of the steel bars; therefore, the processing is more continuous, which helps to reduce the workload and improve work efficiency.

[0031] 2. After the push plate pushes the steel bar into the installation groove on the rotating drum, the push plate is reset. During the reset process of the push plate, the support block can be driven upward by the driving component. Therefore, there is no need to set up other power sources during the upward movement of the support block, which is more energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following is combined with Figure 1-11 This application is described in further detail. Example 1

[0057] The embodiment of the present application discloses a support frame that facilitates the processing of threaded steel bars. Figure 1The support frame for processing threaded steel bars includes a frame body, which includes a support plate 1 and support legs 2. The support plate 1 is horizontally arranged, and four support legs 2 are provided and respectively fixedly connected to the four corners of the bottom end of the support plate 1. A mounting plate 14 is fixedly connected to the top wall of the support plate 1; two mounting plates 14 are provided and are symmetrically arranged.

[0058] Reference Figure 1 and Figure 2 , a transfer mechanism 3 is provided on the support plate 1, and the transfer mechanism 3 includes a rotating power member 31, a rotating drum 32 and a baffle 33. The rotating power member 31 is a motor, and the rotating power member 31 is fixedly connected to one of the mounting plates 14 by bolts, and the output shaft of the rotating power member 31 is arranged along the length direction of the support plate 1. The rotating drum 32 is arranged between the two mounting plates 14, and the two ends of the rotating drum 32 are respectively rotatably connected to the two mounting plates 14. One end of the rotating drum 32 is coaxially fixedly connected to the output shaft of the rotating power member 31. An installation groove 321 is provided on the outer wall of the rotating drum 32 along its own axial direction, and the installation grooves 321 are provided with four and arranged in a circumferential array, and the installation grooves 321 can be used to accommodate the steel bars 19. The baffle frame 33 is fixedly connected between the two mounting plates 14, and the main body of the baffle frame 33 is arranged in an arc shape; the baffle frame 33 is arranged around the outer side of the rotating drum 32. One end of the baffle 33 is the feeding side of the rotating drum 32, for the steel bars 19 to enter the mounting groove 321 on the rotating drum 32; the other end of the baffle 33 is the discharging side of the rotating drum 32, for the steel bars 19 in the mounting groove 321 on the rotating drum 32 to fall out.

[0059] Therefore, after the steel bar 19 enters the installation groove 321 on the rotating drum 32 from the feeding side, the rotating power member 31 drives the rotating drum 32 to rotate, and the rotating drum 32 can drive the steel bar 19 to rotate; the blocking frame 33 can block the steel bar 19 in the installation groove 321 to prevent the steel bar 19 from falling out of the installation groove 321. When the installation groove 321 rotates to the discharge side of the rotating drum 32, the opening of this installation groove 321 faces downward, so after losing the blocking of the blocking frame 33, the steel bar 19 in the installation groove 321 can fall.

[0060] Reference Figure 3 A guide plate 15 is fixedly connected to the top wall of the support plate 1, and the guide plate 15 is located between the two mounting plates 14; the guide plate 15 is arranged in a V shape, and the opening of the guide plate 15 faces upward. The guide plate 15 is located on one side of the rotating drum 32, and the side of the guide plate 15 close to the rotating drum 32 faces the feeding side of the rotating drum 32.

[0061] Reference Figure 4, a feeding mechanism 5, a clamping mechanism 6 and a feeding mechanism 7 are also provided on the support plate 1. The feeding mechanism 5 includes a first power telescopic member 51 and a push plate 52. The first power telescopic member 51 is arranged along the width direction of the support plate 1, and two first power telescopic members 51 are provided and are respectively located at both ends of the support plate 1. The first power telescopic member 51 is an electric push rod, and the fixed end of the first power telescopic member 51 is fixedly provided on the support plate 1. The push plate 52 includes a connecting portion 521 and a push portion 522, and the connecting portion 521 is arranged along the length direction of the support plate 1; the two ends of the connecting portion 521 are respectively fixedly connected to the movable ends of the two first power telescopic members 51. The push portion 522 is vertically fixedly connected to the connecting portion 521, and two push portions 522 are provided and are respectively located at both ends of the connecting portion 521; the guide plate 15 is located between the two push portions 522. Therefore, when the steel bar 19 falls onto the top surface of the guide plate 15, the first power telescopic member 51 drives the push plate 52 to slide toward the side close to the rotating drum 32, and the push plate 52 can push the steel bar 19 on the guide plate 15 to slide until the steel bar 19 is pushed into the installation groove 321 on the feeding side of the rotating drum 32.

[0062] Reference Figure 2 and Figure 4 The clamping mechanism 6 includes a bottom plate 61, a pressure plate 62 and a driving member 63. The bottom plate 61 and the pressure plate 62 are both arranged along the length direction of the support plate 1; the bottom plate 61 is fixedly connected to the top wall of the support plate 1, and a V-shaped groove is provided on the top of the bottom plate 61; the pressure plate 62 is arranged directly above the bottom plate 61, and the pressure plate 62 is slidably arranged in the vertical direction; a rubber pad is fixedly bonded to the bottom wall of the pressure plate 62. There are two driving members 63, and they are respectively located at the two ends of the pressure plate 62. The driving member 63 is an electric push rod, and the driving member 63 is arranged vertically; the fixed end of the driving member 63 is fixedly arranged on the mounting plate 14, and the movable end of the driving member 63 is fixedly connected to the pressure plate 62. A guide plate 16 is also arranged on the support plate 1 below the rotating drum 32, and the guide plate 16 is fixedly connected between the two mounting plates 14, and the guide plate 16 is arranged obliquely. The higher end of the guide plate 16 is located at the discharge side of the drum 32, and the lower end of the guide plate 16 is located at one side of the bottom plate 61. Therefore, the steel bar 19 dropped from the mounting groove 321 at the discharge side of the drum 32 can roll down along the guide plate 16 to the bottom plate 61, and then the driving member 63 drives the pressing plate 62 to move downward, so that the rubber pad on the pressing plate 62 can be pressed against the top wall of the steel bar 19, thereby clamping and fixing the steel bar 19. The device for processing the steel bar 19 is placed at one end of the support plate 1, so that the end of the clamped steel bar 19 can be processed.

[0063] The unloading mechanism 7 includes a connecting rod 71 and a push block 72. The connecting rod 71 is arranged along the width direction of the support plate 1, and two connecting rods 71 ​​are provided and fixedly connected to the two ends of the push plate 52 respectively. There are two push blocks 72 and they correspond to the two connecting rods 71 ​​respectively, and the push blocks 72 are fixedly connected to the ends of the connecting rod 71; the push blocks 72 are arc-shaped blocks. Therefore, when the first power telescopic member 51 drives the push plate 52 to slide toward the side close to the rotating drum 32, the push plate 52 drives the push block 72 to slide through the connecting rod 71, and the two push blocks 72 can respectively press against the two ends of the steel bar 19 placed on the bottom plate 61, and then the push block 72 can push the steel bar 19 down when sliding, thereby completing the unloading process of the processed steel bar 19. Among them, the connecting rod 71 and the push plate 52 are detachably connected by bolts, so the installation position of the connecting rod 71 can be adjusted according to the length of the steel bar 19, so that the push block 72 at the end of the connecting rod 71 can abut against the end of the steel bar 19.

[0064] Reference Figure 1 and Figure 5 , a blanking mechanism 4 is also provided on the support plate 1, and the blanking mechanism 4 includes a charging box 41, a partition 42, a support block 43, a limit assembly 44 and a driving assembly 45. The charging box 41 is fixedly connected to the top wall of the support plate 1, and the charging box 41 is located above the guide plate 15. The charging box 41 is a rectangular box body with an open top. The length direction of the charging box 41 is parallel to the length direction of the support plate 1, and the partition 42 is arranged along the length direction of the charging box 41; there are multiple partitions 42, and they are arranged in parallel at intervals inside the charging box 41; the partition 42 divides the inside of the charging box 41 into multiple accommodating cavities 411 of the same width. The support block 43 is arranged along the length direction of the partition 42, and the number of the support blocks 43 is the same as the number of the accommodating cavities 411, and each support block 43 corresponds to a accommodating cavity 411. In each accommodating cavity 411, a plurality of steel bars 19 are installed at the top of the support block 43, and the plurality of steel bars 19 are stacked in the vertical direction.

[0065] Reference Figure 5, vertical guide rods 412 are welded on the bottom walls at both ends of the accommodating chamber 411, and guide holes 432 are provided at both ends of the support block 43. The guide rods 412 are slidably inserted into the guide holes 432, so that the support block 43 is slidably arranged in the accommodating chamber 411 along the vertical direction. Furthermore, a protrusion can be provided at the top of the guide rod 412 to limit the support block 43 and prevent the support block 43 from directly sliding out of the guide rod 412. Both ends of the support block 43 are fixedly connected with protrusions 433, and the side walls at both ends of the accommodating chamber 411 are provided with sliding grooves 413 along the vertical direction; one end of the protrusion 433 passes through the sliding groove 413, and the protrusion 433 can slide along the sliding groove 413. Therefore, after the support block 43 moves upward for a distance, the steel bars 19 above the support block 43 can move upward along with it, and the topmost steel bars 19 can move to the outside of the accommodating cavity 411, and then fall from the top of the charging box 41 to the guide plate 15 below.

[0066] The end surface of the top of the charging box 41 is inclined, and the top of the support block 43 is provided with an inclined surface 431 in the same inclined direction as the top of the charging box 41. Therefore, the steel bars 19 in the smallest accommodating cavity 411 can be dropped first, and when the steel bars 19 in this accommodating cavity 411 have all dropped, the steel bars 19 in the adjacent accommodating cavity 411 can be dropped; after the steel bars 19 move to the top of the charging box 41, they can first drop onto the inclined surface 431 above the top support block 43, then drop down along the inclined surface 431, and finally drop onto the guide plate 15 below.

[0067] Reference Figure 6 , the limiting assembly 44 is arranged on the outside of the charging box 41. The limiting assembly 44 includes a limiting claw 441, a stopper 442 and a first elastic member. There are multiple groups of limiting claws 441, and each group of limiting claws 441 corresponds to a protrusion 433 at the end of a support block 43; both sides of the protrusion 433 are fixedly connected with the limiting claws 441, and the two limiting claws 441 are symmetrically arranged. There are multiple rows of stoppers 442, and each row of stoppers 442 corresponds to a support block 43; each row of stoppers 442 includes multiple groups evenly spaced in the vertical direction; each group includes two symmetrically arranged stoppers 442, and the stoppers 442 are hinged to the outer wall of the end of the accommodating cavity 411. The first elastic member is a torsion spring, and the number of the first elastic members is the same as the number of the stoppers 442, and each first elastic member corresponds to a stopper 442. The first elastic member is fixedly connected between the stopper 442 and the outer wall of the end of the accommodating cavity 411. A stopper 414 is fixedly connected to the outer wall of the accommodating cavity 411 below each stopper 442 . The first elastic member causes the stopper 442 to press against the stopper 414 , and the stopper 414 prevents the stopper 442 from further rotating downward.

[0068] Therefore, when the support block 43 moves upward, the protrusion 433 can be driven to move upward, and the stop claws 442 on both sides can rotate upward to avoid the support block 43; when the support block 43 tends to move downward, the limit claws 441 are pressed against the stop claws 442, and the stop claws 442 can no longer rotate downward, thereby limiting the downward movement of the support block 43. That is, the setting of the limit assembly 44 allows the support block 43 to only move upward, but not downward.

[0069] Furthermore, vertical gripping rods are provided on both sides of the protrusion 433, one of which is hinged to the stopper 442 on one side, and the other is hinged to the stopper 442 on the other side. Therefore, by sliding the two gripping rods toward the side away from each other, the stopper 442 on both sides can be rotated upward, so that the stopper 442 is separated from the contact with the limit claw 441, thereby releasing the restriction on the sliding of the support block 43, facilitating the support block 43 at the top of the charging box 41 to slide to the bottom of the charging box 41, and completing the reset of the support block 43.

[0070] Reference Figure 6 and Figure 7 The driving assembly 45 includes an active rack 451, a driven rack 452, a driving gear 453, a driven gear 454, a transmission component 455 and a locking member. The active rack 451 is arranged along the width direction of the support plate 1, and the active rack 451 is fixedly connected to the end of the push plate 52. The driven rack 452 is arranged vertically, and the driven rack 452 is slidably arranged along the vertical direction; a connecting strip 4521 is welded to the top of the driven rack 452, and the connecting strip 4521 is parallel to the active rack 451. The connecting bar 4521 is provided with a plurality of through holes 45211 evenly spaced along its length direction, and each protrusion 433 at the end of each support block 43 is provided with a threaded hole 4331; the spacing between two adjacent threaded holes 4331 is the same as the spacing between two adjacent through holes 45211, so when the connecting bar 4521 and the protrusion 433 are at the same height, the through holes 45211 on the connecting bar 4521 and the threaded holes 4331 on the protrusion 433 are in a coaxial state. The locking member is a locking bolt 456, which is inserted into one of the through holes 45211 and threadedly connected with the corresponding threaded hole 4331, so that the connecting bar 4521 and the corresponding protrusion 433 can be fixedly connected, so that when the connecting bar 4521 moves upward, the corresponding support block 43 can be driven to move upward.

[0071] Reference Figure 7The support plate 1 is also provided with a receiving groove 18, in which the driving gear 453 and the driven gear 454 are both arranged. The driving gear 453 and the driven gear 454 are coaxially arranged, and the axes of both are parallel to the axis of the drum 32; the driving gear 453 and the driven gear 454 are both rotatably arranged on the inner wall of the receiving groove 18. The top of the driving gear 453 can mesh with the driving rack 451, and the driven gear 454 meshes with the driven rack 452. The transmission component 455 is arranged between the driving gear 453 and the driven gear 454, and is used to transmit the rotation of the driving gear 453 to the driven gear 454.

[0072] Reference Figure 8 , Fig. 9 and Fig.10 The transmission component 455 includes a ratchet 4551, a pawl 4552 and a third elastic member. The ratchet 4551 is coaxially fixedly connected to the side of the driving gear 453 close to the driven gear 454. The pawl 4552 is arranged on the side of the driven gear 454 close to the driving gear 453. There are multiple pawls 4552, which are arranged in a circular array; the pawl 4552 is hinged to the driven gear 454, and the hinge axis of the pawl 4552 is parallel to the axis of the driven gear 454. The third elastic member is a torsion spring, and the number of the third elastic members is the same as the number of the pawls 4552, and each third elastic member corresponds to a pawl 4552; the third elastic member is fixedly connected between the pawl 4552 and the driven gear 454.

[0073] When the push plate 52 slides, it drives the active rack 451 to slide. When the active rack 451 and the active gear 453 are meshed, the sliding of the active rack 451 can make the active gear 453 rotate. The active gear 453 drives the ratchet 4551 to rotate. The ratchet 4551 is pressed against the pawl 4552. Therefore, the rotation of the ratchet 4551 can make the pawl 4552 rotate accordingly, so that the driven gear 454 rotates. The driven gear 454 drives the driven rack 452 to slide. The driven rack 452 drives the corresponding support block 43 to move upward, so that the steel bar 19 above the support block 43 moves upward for a distance, and then the topmost steel bar 19 falls from the loading box 41 to the top surface of the guide plate 15.

[0074] When the push plate 52 slides toward the side closer to the rotating drum 32, the push plate 52 can push the steel bar 19 that falls on the guide plate 15 to move, and at the same time, the active rack 451 drives the active gear 453 to rotate, and the active gear 453 drives the ratchet 4551 to rotate, and at this time the ratchet pawl 4552 can rotate to avoid, so that the driven gear 454 can remain stationary, thereby making the driven rack 452 remain stationary, and the support block 43 can remain at the current position without moving.

[0075] Therefore, each time the push plate 52 performs reciprocating motion, it can drive the support block 43 to move the same distance upward, and after pushing down a steel bar 19 at the top of the corresponding accommodating cavity 411, the support block 43 stays at the current position; it reciprocates in this way until the support block 43 moves to the top of the charging box 41, at which time all the steel bars 19 in this accommodating cavity 411 are pushed out.

[0076] Reference Figure 8 Furthermore, the support plate 1 is also fixedly connected with a support plate 8, which is arranged vertically; the support plate 8 is slidably provided with a mounting block 9 in the vertical direction, and two mounting blocks 9 are provided and arranged at intervals in the vertical direction. The mounting block 9 is fixedly connected with a limiting block 10, and a limiting groove 81 is provided in the vertical direction on the support plate 8, and the limiting block 10 is slidably provided in the limiting groove 81. The mounting block 9 is fixedly connected with a support rod 11, and the support rod 11 is arranged along the length direction of the support plate 1. The driven rack 452 is provided with a mounting hole for the support rod 11 to penetrate, and the support rod 11 is slidably penetrated on the driven rack 452. An anti-dropping block 111 is fixedly connected to one end of the support rod 11 passing through the driven rack 452, so that the driven rack 452 can be prevented from sliding out of the end of the support rod 11. A second elastic member 12 is fixedly connected between the driven rack 452 and the mounting block 9, and the second elastic member 12 is sleeved on the outside of the support rod 11. The second elastic member 12 is a spring, and the second elastic member 12 is in a compressed state. Therefore, under normal conditions, the driven rack 452 is meshed with the driven gear 454, and the driven rack 452 can slide in the vertical direction; in addition, the driven rack 452 can also slide in the horizontal direction until it is disengaged from the driven gear 454.

[0077] After all the steel bars 19 in one of the accommodating chambers 411 have fallen, it is necessary to unscrew the locking bolt 456 connected between the connecting bar 4521 and the corresponding support block 43, and then slide the driven rack 452 to a state separated from the driven gear 454; then slide the driven rack 452 downward to reset the driven rack 452 to its initial state; then release the driven rack 452, and the second elastic member 12 drives the driven rack 452 to slide, so that the driven rack 452 is meshed with the driven gear 454. Then, the connecting bar 4521 at the top of the driven rack 452 and the protrusion 433 at the end of the support block 43 in the next accommodating chamber 411 are fixedly connected by the locking bolt 456, and the steel bars 19 in the second accommodating chamber 411 can be dropped. Then, this process is repeated until all the steel bars 19 in each accommodating chamber 411 have fallen, and at this time, the loading box 41 is in an empty state, and each support block 43 is located at the top of the loading box 41. Then the holding rod can be slid to rotate the stop claw 442, thereby canceling the locking of the limit claw 441, and then the support block 43 is slid to the bottom end of the charging box 41, and then the steel bar 19 to be processed is placed in the charging box 41.

[0078] In this embodiment, the support block 43 is set to slide in the vertical direction, and the limiting assembly 44 and the driving assembly 45 are only set at one end of the support block 43 to complete the locking of the support block 43; in other embodiments, the limiting assembly 44 and the driving assembly 45 can be set at both ends of the support block 43, so as to enhance the supporting effect of the support block 43 and further improve the stability of the support block 43 after locking.

[0079] Reference Figure 4 In addition, in order to enhance the consistency of processing of the steel bar 19, a pusher 17 for adjusting the installation position of the steel bar 19 is also provided on the support plate 1. The pusher 17 is an electric push rod. The pusher 17 is fixedly connected to the top wall of the support plate 1. The pusher 17 and the bottom plate 61 are located in the same straight line direction, and the movable end of the pusher 17 faces the bottom plate 61. Therefore, after the steel bar 19 in the installation groove 321 falls onto the bottom plate 61 through the guide plate 16, the pusher 17 can push the steel bar 19 to move a certain distance along the length direction of the bottom plate 61; therefore, even if the length of each steel bar 19 is different and the position of the steel bar 19 in the installation groove 321 is different, after being pushed by the pusher 17, the processing end of the steel bar 19 can be in the same position, thereby ensuring the consistency of processing of each steel bar 19.

[0080] The implementation principle of Example 1 is as follows: the operator first loads the steel bars 19 into the loading box 41 in sequence, and then fixes and subsequently processes the steel bars 19. During the processing, the first power telescopic member 51 drives the push plate 52 to move toward the side close to the rotating drum 32, and the push plate 52 can push the steel bars 19 on the guide plate 15 to move until the steel bars 19 are pushed into the mounting groove 321 on the feeding side of the rotating drum 32. At the same time, the push plate 52 can drive the push block 72 to move through the connecting rod 71, push down the processed steel bars 19 on the bottom plate 61, and complete the unloading process of the steel bars 19.

[0081] Then the push plate 52 moves to the side away from the drum 32 to reset, and then the rotating power member 31 drives the drum 32 to rotate a certain angle, so that the steel bars 19 in the installation slot 321 rotate accordingly; when the installation slot 321 rotates to the discharge side of the drum 32, the steel bars 19 in the installation slot 321 can fall onto the guide plate 16, and then roll down along the guide plate 16 to the bottom plate 61. Then the push member 17 pushes the steel bars 19 for a distance, so that the end of the steel bars 19 moves to the processing position at one end of the support plate 1. Then the driving member 63 drives the pressing plate 62 to move downward, so that the steel bars 19 can be clamped and fixed between the pressing plate 62 and the bottom plate 61. At this time, the end of the steel bars 19 can be processed.

[0082] When the push plate 52 moves toward the side away from the rotating drum 32, the support block 43 can be moved up a certain distance through the driving assembly 45, so that the topmost steel bar 19 moves to the outside of the accommodating cavity 411, and then the topmost steel bar 19 can fall from the top of the loading box 41 to the top surface of the guide plate 15, completing the dropping of the next steel bar 19.

[0083] After the steel bars 19 on the bottom plate 61 are processed, the driving member 63 moves the pressing plate 62 upward to release the steel bars 19; the pushing plate 52 moves toward the side close to the rotating drum 32, pushes the steel bars 19 on the guide plate 15 into the installation groove 321, and pushes the processed steel bars 19 on the bottom plate 61 down through the pushing block 72; then the rotating power member 31 rotates again, and then moves the steel bars 19 in the installation groove 321 to the bottom plate 61. Then repeat the above process until all the steel bars 19 in the accommodating cavity 411 at the lower end of the charging box 41 are dropped, and at this time, the supporting block 43 in this accommodating cavity 411 is located at the top of the accommodating cavity 411.

[0084] Next, the connecting strip 4521 at the end of the driven rack 452 and the protrusion 433 on the support block 43 at the top of the accommodating chamber 411 are disassembled, and the driven rack 452 is slid to the side away from the driven gear 454, so that the driven rack 452 is disengaged from the driven gear 454; then the driven rack 452 is moved down, so that the connecting strip 4521 at the top of the driven rack 452 and the protrusion 433 on the support block 43 at the bottom of the next accommodating chamber 411 are at the same height, and then the driven rack 452 is loosened, and the second elastic member 12 makes the driven rack 452 and the driven gear 454 mesh again. Then, the connecting strip 4521 at the top of the driven rack 452 and the protrusion 433 on the corresponding support block 43 are fixedly connected by the locking bolt 456. Then, the steel bars 19 in this accommodating chamber 411 can be blanked.

[0085] By analogy, when all the steel bars 19 in the loading box 41 have fallen down, each support block 43 is located at the top of the corresponding accommodating cavity 411; at this time, the blocking claw 442 can be rotated by holding the rod, so that the blocking claw 442 is disengaged from the abutment with the limiting claw 441, thereby sliding the support block 43 downward to the bottom of the accommodating cavity 411, and then the next batch of steel bars 19 can be loaded into the loading box 41. Example 2

[0086] Reference Fig.11, the difference between this embodiment and embodiment 1 is that the top of the charging box 41 in this embodiment is also fixedly connected with a second power telescopic member 13, the second power telescopic member 13 is an electric push rod, the second power telescopic member 13 is arranged along the inclined direction of the top of the charging box 41, and the movable end of the second power telescopic member 13 faces the lower side of the top of the charging box 41. The movable end of the second power telescopic member 13 is fixedly connected with an arc plate 131, and the arc plate 131 is arranged along the length direction of the charging box 41. A controller is arranged on the charging box 41, and a sensor is arranged at the top of the charging box 41, and the sensor is a photoelectric sensor; the detection optical path of the sensor is parallel to the length direction of the second power telescopic member 13, so the sensor can detect whether there is a steel bar 19 at the top of the charging box 41. The controller is electrically connected to the sensor and the second power telescopic member 13, respectively.

[0087] Therefore, when the sensor detects the presence of steel bars 19 at the top of the charging box 41, the sensor can transmit a signal to the controller, and the controller causes the movable end of the second power telescopic member 13 to extend, and the second power telescopic member 13 drives the arc plate 131 to slide, and the arc plate 131 can push the steel bars 19 at the top of the charging box 41 to move downward, thereby pushing the steel bars 19 down, avoiding the steel bars 19 moved to the top of the charging box 41 from getting stuck on the top of the charging box 41, thereby ensuring the smooth progress of the blanking process.

[0088] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
