Description

Technical Field

[0001] The present invention relates to the technical field of steel bar shearing, and particularly relates to a steel bar shearing device. Background Art

[0002] In construction projects, as the main structural material, the length and shape of steel bars need to be precisely cut according to specific construction design requirements. Through shearing, the steel bars can be cut into the required lengths to ensure that they can perfectly fit into the concrete structure and meet the bearing capacity and stability requirements of the building design.

[0003] Chinese Patent with Publication No. CN112643124B discloses a cold shearing device and shearing process for precision rolled threaded steel, including a base, a first electric telescopic rod, a support seat, a second electric telescopic rod, a shearing knife, a fixed arm, a fixed foot, an auxiliary support assembly, and a threaded steel storage assembly. By opening a first limiting groove on the base, the arrangement time of the threaded steel can be reduced; by fixedly connecting a lifting rod and a support roller on the outside of the base, it can not only support the threaded steel entering the shearing area, but also support the cut spare threaded steel segments, so that the threaded steel always remains horizontal during the shearing process, without manual support, ensuring smooth feeding.

[0004] However, in the actual implementation of the above patent, when the conveyor belt transports the threaded steel to the support roller, it cannot ensure that the threaded steel on the conveyor belt is in a flat state, nor can it ensure that the threaded steel on the conveyor belt is aligned with the third limiting groove on the support roller. Therefore, some threaded steel will abut against the support roller and cannot enter the third limiting groove, resulting in unsmooth feeding and requiring manual cooperation to flatten and arrange the threaded steel on the conveyor belt, which not only consumes labor but also affects work efficiency.

[0005] Therefore, there is a need in the art for a steel bar shearing device to solve the above problems. Summary of the Invention

[0006] The present invention provides a steel bar shearing device, aiming to solve the problem that the steel bar shearing device in the related art cannot flatten and arrange the steel bars at the feeding position, resulting in unsmooth feeding and shearing and affecting work efficiency.

[0007] A steel bar shearing device of the present invention includes a frame, a cutting knife mechanism and a feeding mechanism arranged on the frame. The feeding mechanism is used to transport steel bars to the cutting knife mechanism. Defining the feeding direction of the feeding mechanism as the front, the feeding mechanism includes feeding rollers and a material gathering plate. The feeding rollers are arranged at intervals in the front-rear direction, and a plurality of feeding grooves are evenly arranged at intervals in the left-right direction on the outer circumference of the feeding rollers. A first driving component for driving the feeding rollers to rotate and a second driving component for driving the feeding rollers to move in the left-right direction are arranged on the frame;

[0008] The gathering plates are spaced apart along the front-to-back direction, and one end of the gathering plates is rotatably connected to the frame. The frame is provided with a driving component three for driving the gathering plates to rotate. When the gathering plates are tilted downward from left to right, the steel bars are gathered on the feed roller near the right end. When the gathering plates rotate to a horizontal state, the driving component two drives the feed roller to move to the right, and the frame pushes the gathered steel bars down into the feed trough on the feed roller.

[0009] The steel bars delivered to the feed roller are gathered to one side of the feed roller by the gathering plate, and the feed roller is pulled to make the frame push the gathered steel bars to fall into the feed trough, so as to achieve the flattening of the steel bars, thus avoiding the problem of unsmooth feeding caused by the accumulation of steel bars. Then, the drive component is controlled to drive the feed roller to rotate, and the feed roller conveys the neatly arranged steel bars to the bottom of the cutting knife mechanism for shearing, thus avoiding the problem of large shearing resistance or even failure of smooth shearing caused by the accumulation of steel bars.

[0010] Preferably, the driving component includes a rotating shaft rotatably connected to the frame and a motor driving the rotating shaft to rotate. The number of the rotating shafts corresponds to the number of feed rollers. The feed rollers are connected to the corresponding rotating shafts and are coaxially arranged. The rotating shafts are connected through a transmission component. The motor is fixedly mounted on the frame, and the output end of the motor is fixedly connected to one of the rotating shafts.

[0011] Preferably, the transmission assembly includes a transmission wheel and a transmission belt, each rotating shaft is fixedly connected with a transmission wheel, and the transmission wheels of two adjacent rotating shafts are connected by a transmission belt.

[0012] The motor drives the rotating shaft connected to it to rotate, and the rotating shaft drives other rotating shafts to rotate synchronously through the cooperation of the transmission wheel and the transmission belt, thereby driving all the feeding rollers to rotate synchronously and realizing the synchronous transportation of the steel bars.

[0013] Preferably, the feed roller is sleeved on the outer periphery of the rotating shaft, and a convex strip extending along its axial direction is fixedly connected to the rotating shaft, and a slide groove adapted to the convex strip is opened in the feed roller. The feed roller is slidably connected to the rotating shaft along the left and right directions through the cooperation of the slide groove and the convex strip. The driving component 2 includes an electric push rod fixedly mounted on the frame and a sleeve slidably connected to the rotating shaft. The sleeve is rotatably connected to the corresponding feed roller, and the sleeves on each rotating shaft are fixedly connected through a connecting plate. The driving end of the electric push rod is fixedly connected to the connecting plate, and the electric push rod drives the connecting plate to drive each sleeve and the feed roller to move left and right.

[0014] Through the cooperation of the slide groove and the convex strip, the feeding roller can not only rotate synchronously with the rotating shaft, but also slide left and right relative to the rotating shaft.

[0015] Preferably, the right end of the material collecting plate is rotatably connected to the frame. A receiving groove is formed on the left side of the frame. A first spring for supporting the left end of the material collecting plate is fixedly connected in the receiving groove. When the material collecting plate is not affected by external forces, the first spring pushes the left end of the material collecting plate against the top of the receiving groove, and the material collecting plate is in a state of inclining downward from left to right.

[0016] By arranging the first spring, the left end of the material collecting plate is supported, so that the material collecting plate can maintain an inclined state. At the same time, when the third driving component drives the material collecting plate to rotate, the material collecting plate can overcome the elastic force of the spring and move to a horizontal state, avoiding the influence of the material collecting plate on the flat laying of steel bars.

[0017] Preferably, the third driving component includes a driving member and a pulling block. A through groove extending in the left-right direction is formed on the frame. The pulling block is slidably arranged in the through groove. A fixing plate is fixedly connected to the bottom of the material collecting plate near the right end. A pulling plate extends upward from the top of the pulling block. The pulling plate is located on the left side of the fixing plate. When the driving member drives the pulling block to move rightward, the pulling plate pushes the fixing plate to drive the material collecting plate to rotate downward.

[0018] Preferably, a limiting block is slidably connected to the pulling block in the vertical direction. The limiting block is elastically connected to the pulling block through a second spring. When the left end of the material collecting plate abuts against the top of the receiving groove, the limiting block is located in the through groove, and the second spring is in a stretched state;

[0019] The driving member is cooperatively connected with the limiting block through a first limiting structure. The driving member pulls the limiting block and the pulling block to move rightward through the first limiting structure. When the limiting block disengages from the receiving groove, the second spring drives the limiting block to move downward. The limiting block abuts against the frame, and the first limiting structure cancels the connection between the driving member and the limiting block. The material collecting plate is in a horizontal state.

[0020] By arranging the limiting block, when the driving member drives the pulling block to move rightward until the limiting block disengages from the through groove, the limiting block can move downward to cooperate with the frame to realize the limitation of the current position of the pulling block, without the driving member continuing to act on the pulling block.

[0021] Preferably, the first limiting structure includes a mounting plate and a mounting rod fixedly connected to the mounting plate. A stop block and an L-shaped pushing block are fixedly connected to the bottom of the mounting rod. An inclined wedge surface is arranged at a position near the bottom on the right side of the limiting block. When the limiting block is in the through groove, it is located between the stop block and the L-shaped pushing block. During the process of the mounting plate moving rightward, the stop block pulls the limiting block and the pulling block to move rightward. When the limiting block moves out of the through groove, it disengages from contact with the stop block. During the process of the mounting plate moving leftward, the horizontal part of the L-shaped pushing block presses the inclined wedge surface to drive the limiting block to move upward until the limiting block disengages from contact with the right side wall of the frame, and the limiting block enters the through groove following the mounting rod.

[0022] Preferably, the driving member includes a threaded section provided on the rotating shaft and a limiting rod that cooperates with the threaded section. The mounting plate is slidably engaged with two adjacent rotating shafts in the left-right direction. The threaded section is provided on one of the rotating shafts, and the limiting rod penetrates the mounting plate vertically. A limiting cap is fixedly connected to the top of the limiting rod. A lifting structure is fixedly connected to the connecting plate, and a second limiting structure is fixedly connected to the frame. During the rightward movement of the feeding roller, the lifting structure jacks up the limiting rod, causing the limiting rod to disengage from the threaded section. The connecting plate pushes the mounting plate to move rightward. When the feeding roller moves leftward, the second limiting structure restricts the mounting plate from moving with the connecting plate. The lifting structure cancels the jacking of the limiting rod, and the limiting rod drops into the threaded section. When the rotating shaft rotates, through the cooperation of the threaded section and the limiting rod, the mounting plate is driven to move leftward.

[0023] Preferably, the second limiting structure includes a connecting rod fixedly connected to the frame. A baffle is fixedly connected to the bottom of the connecting rod. A convex block extends from the right side of the mounting plate. A resilient block is elastically connected to the top of the convex block. First inclined surfaces are respectively provided on the left and right sides of the resilient block. When the mounting plate moves rightward until the resilient block contacts the baffle, the baffle squeezes the right first inclined surface to cause the resilient block to move downward. When the mounting plate moves leftward, the baffle squeezes the left first inclined surface to cause the resilient block to move downward. The lifting structure includes lifting plates symmetrically arranged on the front and rear of the connecting plate. Second inclined surfaces and flat surfaces are provided on the top of the lifting plates. When the limiting rod is located within the threaded section, the lifting plates push the limiting cap through the second inclined surfaces, causing the limiting rod to move upward.

[0024] The beneficial effects of the present invention are as follows: The present invention realizes the automatic flattening and sorting of steel bars, making the steel bars entering below the cutting knife arranged neatly. This not only facilitates the smooth feeding and shearing, but also eliminates the need for manual cooperation in sorting the steel bars, saving labor and improving work efficiency at the same time.

Detailed implementation manners

[0037] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] As Figures 1 to 10As shown in the figure, a steel bar shearing device of the present invention includes a frame 1, a cutting tool mechanism and a feeding mechanism arranged on the frame 1. The feeding mechanism is used to convey steel bars to the cutting tool mechanism, and the feeding direction of the feeding mechanism is defined as the front. The cutting tool mechanism includes a mounting frame 11 mounted on the frame 1 and a cutting tool (not shown in the figure) slidably connected to the mounting frame 11 in the vertical direction. An electric push rod 12 for driving the cutting tool to move up and down is arranged on the mounting frame 11. A pressing mechanism is further arranged behind the cutting tool mechanism. The pressing mechanism includes an electric push rod 13 mounted on the mounting frame 11 and a pressing plate 14 fixedly connected to the driving end of the electric push rod 13. The electric push rod 13 drives the pressing plate 14 to press down the steel bar on the frame 1 to ensure the stability of the steel bar during cutting by the cutting tool, and to avoid problems such as shaking of the steel bar and uneven cutting of the steel bar during the process of shearing the steel bar.

[0039] The feeding mechanism includes feeding rollers 2 and gathering plates 3. The feeding rollers 2 are distributed at intervals in the front-rear direction, and a plurality of feeding grooves 21 are evenly arranged at intervals in the left-right direction on the outer periphery of the feeding rollers 2. A first driving assembly for driving the feeding rollers 2 to rotate and a second driving assembly for driving the feeding rollers 2 to move in the left-right direction are arranged on the frame 1. The gathering plates 3 are distributed at intervals in the front-rear direction, and the right end of the gathering plate 3 is rotatably connected to the frame 1. A third driving assembly for driving the gathering plate 3 to rotate is arranged on the frame 1.

[0040] As Figures 1 to 4 shown, when the steel bar is conveyed onto the feeding roller 2, the gathering plate 3 is in a state of inclining downward from left to right. Under the guidance of the gathering plate 3, the steel bars will gather at the position near the right end of the feeding roller 2. By controlling the third driving assembly to drive the gathering plate 3 to rotate to a horizontal state, the gathering effect of the gathering plate 3 on the steel bars is cancelled. Then, by controlling the second driving assembly to drive the feeding roller 2 to move to the right, the frame 1 pushes the steel bars gathered at the right end of the feeding roller 2 to roll to the left and fall into the feeding grooves 21 on the feeding roller 2, thereby realizing the flattening of the steel bars and avoiding the problem of unsmooth feeding caused by the accumulation of steel bars. In this embodiment, a stop baffle 22 is fixedly connected to the left end of the feeding roller 2 to prevent the stacked steel bars from falling off the feeding roller 2 when rolling to the left. Then, by controlling the first driving assembly to drive the feeding roller 2 to rotate, the feeding roller 2 conveys the neatly arranged steel bars to be sheared under the cutting tool, avoiding the problems of large shearing resistance caused by the accumulation of steel bars and even unable to shear smoothly.

[0041] The present invention realizes the automatic flattening and sorting of steel bars, making the steel bars entering under the cutting tool neatly arranged, which is not only conducive to smooth feeding and shearing, but also does not require manual cooperation to sort the steel bars, saving labor and improving work efficiency at the same time.

[0042] Continue to refer to Figure 1, the first driving assembly includes a rotating shaft 8 rotatably connected to the frame 1 and a motor 15 for driving the rotation of the rotating shaft 8. The number of the rotating shafts 8 corresponds to the number of the feeding rollers 2. The feeding rollers 2 are connected to the corresponding rotating shafts 8 and are coaxially arranged. Each rotating shaft 8 is fixedly connected with a transmission wheel 82, and the transmission wheels 82 of two adjacent rotating shafts 8 are connected by a transmission belt 83. The motor 15 is fixedly installed on the frame 1, and the output end of the motor 15 is fixedly connected with one of the rotating shafts 8. The motor 15 drives the rotating shaft 8 connected thereto to rotate, and this rotating shaft 8 drives other rotating shafts 8 to rotate synchronously through the cooperation of the transmission wheel 82 and the transmission belt 83, so as to drive all the feeding rollers 2 to rotate synchronously and realize the synchronous conveying of the steel bars.

[0043] As Figure 1 and Figure 7 shown, the feeding roller 2 is sleeved on the outer periphery of the rotating shaft 8. A rib extending along its axial direction (not shown in the figure) is fixedly connected to the rotating shaft 8. A sliding groove (not shown in the figure) adapted to the rib is formed in the feeding roller 2. The feeding roller 2 is slidably connected to the rotating shaft 8 in the left-right direction through the cooperation of the sliding groove and the rib, so that the feeding roller 2 can not only rotate synchronously with the rotating shaft 8, but also slide left and right relative to the rotating shaft 8. The second driving assembly includes an electric push rod three 90 fixedly installed on the frame 1 and a sleeve 23 slidably connected to the rotating shaft 8. The sleeve 23 is rotatably connected to the corresponding feeding roller 2. The sleeves 23 on each rotating shaft 8 are fixedly connected by a connecting plate 9. The driving end of the electric push rod three 90 is fixedly connected to the connecting plate 9, and the electric push rod three 90 drives the connecting plate 9 to drive each sleeve 23 and the feeding roller 2 to move left and right.

[0044] As Figure 4 shown, a receiving groove 31 is formed on the left side of the frame 1. A first spring 32 for supporting the left end of the material collecting plate 3 is fixedly connected in the receiving groove 31. When the material collecting plate 3 is not subjected to external force, the first spring 32 pushes the left end of the material collecting plate 3 to abut against the top of the receiving groove 31, and the material collecting plate 3 is in a state of inclining downward from left to right.

[0045] The third driving assembly includes a driving member and a pulling block 4. A through groove 16 extending in the left-right direction is formed on the frame 1. The pulling block 4 is slidably arranged in the through groove 16. A fixing plate 33 is fixedly connected to the bottom of the material collecting plate 3 near the right end. A pulling plate 41 extends upward from the top of the pulling block 4, and the pulling plate 41 is located on the left side of the fixing plate 33. When the driving member drives the pulling block 4 to move to the right, the pulling plate 41 pushes the fixing plate 33 to drive the material collecting plate 3 to rotate downward.

[0046] As Figure 4 and Figure 5As shown, the pulling block 4 is slidably connected to the limiting block 42 in the vertical direction. The limiting block 42 is elastically connected to the pulling block 4 through a second spring (not shown in the figure). When the left end of the material collecting plate 3 abuts against the top of the receiving groove 31, the limiting block 42 is located in the through groove 16, the second spring is in a stretched state, and the bottom of the limiting block 42 closely abuts against the bottom of the through groove 16. When the driving member drives the pulling block 4 to move rightward until the limiting block 42 disengages from the through groove 16, the limiting block 42 moves downward under the elastic force of the second spring, and the material collecting plate 3 rotates to the horizontal state. At this time, even if the material collecting plate 3 has a tendency to rotate upward under the pushing of the first spring 32, since the limiting block 42 abuts against the right side of the frame 1, the pulling block 4 cannot move leftward along the through groove 16, and the material collecting plate 3 can only maintain its current state. Through the cooperation of the limiting block 42 and the frame 1, the position of the pulling block 4 is restricted, and there is no need for the driving member to continue to act on the pulling block 4.

[0047] As Figure 5 and Figure 6 shown, the driving member is cooperatively connected to the limiting block 42 through a first limiting structure. The first limiting structure includes a mounting plate 5 and a mounting rod 51 fixedly connected to the left side of the mounting plate 5. A stop block 52 and an L-shaped pushing block 53 are fixedly connected to the bottom of the mounting rod 51. An inclined wedge surface 43 is provided at a position near the bottom on the right side of the limiting block 42.

[0048] When the limiting block 42 is in the through groove 16, it is located between the stop block 52 and the L-shaped pushing block 53. During the process of the mounting plate 5 moving rightward, the limiting block 42 and the pulling block 4 are pulled rightward through the stop block 52. When the limiting block 42 moves out of the through groove 16, it moves downward under the action of the second spring and disengages from the stop block 52, canceling the connection between the pulling block 4 and the mounting rod 51, completing the pulling of the material collecting plate 3, and keeping the material collecting plate 3 in the horizontal state.

[0049] As Figure 4 , Figure 9 and Figure 10 shown, when it is necessary to release the restriction of the limiting block 42 on the position of the pulling block 4, the mounting plate 5 moves leftward, and the horizontal part of the L-shaped pushing block 53 squeezes the inclined wedge surface 43 on the limiting block 42, causing the limiting block 42 to move upward, disengaging from the abutment with the frame 1. The limiting block 42 enters between the stop block 52 and the L-shaped pushing block 53 and enters the through groove 16 following the movement of the mounting plate 5. The pulling block 4 drives the pulling plate 41 to move leftward, and the material collecting plate 3 rotates upward under the pushing of the first spring 32 to return to the state of inclining downward from left to right.

[0050] As Figure 2 , Figures 6 to 8As shown, the driving member includes a threaded section 81 provided on the rotating shaft 8 and a limiting rod 6 that cooperates with the threaded section 81. The mounting plate 5 is slidably engaged with two adjacent rotating shafts 8 in the left-right direction, and the threaded section 81 is provided on one of the rotating shafts 8. The limiting rod 6 vertically penetrates the mounting plate 5, and a limiting cap 61 is fixedly connected to the top of the limiting rod 6.

[0051] A lifting structure is fixedly connected to the connecting plate 9. The mounting plate 5 is located on the right side of the connecting plate 9. The lifting structure includes lifting plates 91 symmetrically arranged front and rear on the right side of the connecting plate 9. A space for accommodating the limiting rod 6 is formed between the two lifting plates 91, as Figure 4 shown. A flat surface 92 and an inclined surface two 93 are provided at the top of the lifting plate 91, and the inclined surface two 93 slopes downward from left to right.

[0052] Continue to refer to Figures 6 to 8 , a limiting structure two is fixedly connected to the frame 1. The limiting structure two includes a connecting rod 7 fixedly connected to the frame 1. A baffle 71 is fixedly connected to the bottom of the connecting rod 7. A convex block 54 extends from the right side of the mounting plate 5. An installation groove is formed at the top of the convex block 54, and an elastic block 55 is elastically connected in the installation groove. Inclined surfaces one 56 are respectively provided on the left and right sides of the elastic block 55. The inclined surface one 56 on the left side of the elastic block 55 slopes upward from left to right, and the inclined surface one 56 on the right side of the elastic block 55 slopes downward from left to right.

[0053] When the steel bars gather at a position near the right end of the feeding roller 2, it is necessary to rotate the material gathering plate 3 to a horizontal state and pull the feeding roller 2 to move to the right. At this time, the limiting block 42 on the pulling block 4 is located in the through groove 16 and is connected to the mounting rod 51. The limiting cap 61 is located on the flat surface 92 of the lifting plate 91, and the bottom end of the limiting rod 6 does not contact the threaded section 81.

[0054] During the process of pulling the connecting plate 9 and the feeding roller 2 to move to the right by the electric push rod three 90, the connecting plate 9 pushes the mounting plate 5 to move to the right. The mounting plate 5 drives the pulling block 4 to move to the right through the cooperation of the blocking block 52 and the limiting block 42, so that the pulling plate 41 on the pulling block 4 cooperates with the fixing plate 33 on the material gathering plate 3 to rotate the material gathering plate 3 to a horizontal state. When the limiting block 42 moves out of the through groove 16, it disconnects from the mounting rod 51. The connecting plate 9 continues to push the mounting plate 5 to move to the right. When the elastic block 55 on the convex block 54 contacts the baffle 71, the baffle 71 squeezes the inclined surface one 56 on the right side of the elastic block 55, causing the elastic block 55 to move downward. After the elastic block 55 passes over the baffle 71, it pops out.

[0055] After the steel bars on the feeding roller 2 are laid flat in the feeding chute 21, it is necessary to drive the feeding roller 2 to move leftward so as to convey the steel bars to the cutting mechanism. During the process that the electric push rod three 90 drives the connecting plate 9 and the feeding roller 2 to move leftward, due to the blocking effect of the baffle 71 and the elastic block 55, the mounting plate 5 cannot move with the connecting plate 9, the limiting cap 61 disengages from the lifting plate 91, and the limiting rod 6 drops into the threaded section 81.

[0056] After the feeding roller 2 moves leftward in place, drive the feeding roller 2 to rotate for feeding. At this time, the rotating shaft 8 drives the mounting plate 5 to move leftward through the cooperation of the threaded section 81 and the limiting rod 6. The baffle 71 presses the inclined surface one 56 on the left side of the elastic block 55, causing the elastic block 55 to move downward, canceling the blocking of the baffle 71 on the elastic block 55. After the steel bars are sent to the cutting mechanism, the L-shaped push block 53 on the mounting plate 5 pushes the limiting block 42 to move upward, and pushes the limiting block 42 and the pulling block 4 to move leftward, canceling the limit on the material gathering plate 3. The material gathering plate 3 returns to the inclined state under the action of the first spring 32. Moreover, during the process that the mounting plate 5 moves leftward, the limiting cap 61 contacts the lifting plate 91 on the connecting plate 9 and moves upward along the inclined surface two 93 on the lifting plate 91. When the limiting cap 61 moves to the flat straight surface 92 of the lifting plate 91, the bottom end of the limiting rod 6 disengages from the threaded section 81, preparing for the mounting plate 5 to move rightward with the connecting plate 9 when laying and arranging the steel bars next time.
