Description

Technical Field

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

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

[0003] The Chinese patent with the announcement number CN112643124B discloses a cold shearing device and shearing process for fine-rolled rebar, including a base, an electric telescopic rod 1, a support seat, an electric telescopic rod 2, a shearing knife, a fixed arm, a fixed foot, an auxiliary support assembly and a rebar storage assembly. The patent can reduce the arrangement time of the rebar by opening a limit groove 1 on the base; by fixing the lifting rod and the support roller on the outside of the base, it can support the rebar entering the shearing area and the spare rebar segment cut off, so that the rebar always remains in a horizontal state during the shearing process, without manual support, to ensure smooth feeding.

[0004] However, in the actual implementation process of the above patent, when the conveyor belt conveys the rebar to the support roller, it is impossible to ensure that the rebar on the conveyor belt is in a flat state, and it is also impossible to ensure that the rebar on the conveyor belt is aligned with the limiting groove three on the support roller. Therefore, some rebars will be pressed against the support roller and unable to enter the limiting groove three, resulting in the inability to feed smoothly. Manual cooperation is required to lay and place the rebar on the conveyor belt, which is not only labor-intensive but also affects work efficiency.

[0005] Therefore, the art needs 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 place the steel bars at the feeding place, resulting in failure to smoothly feed and shear, thus affecting work efficiency.

[0007] A steel bar shearing device of the present invention comprises a frame, a cutting knife mechanism and a feeding mechanism arranged on the frame, wherein the feeding mechanism is used to feed steel bars to the cutting knife mechanism, the feeding direction of the feeding mechanism is defined as the front, the feeding mechanism comprises a feeding roller and a gathering plate, the feeding rollers are spaced apart along the front-back direction, and a plurality of feeding grooves are evenly spaced apart on the outer circumference of the feeding rollers along the left-right direction, and a driving component 1 for driving the feeding rollers to rotate and a driving component 2 for driving the feeding rollers to move along the left-right direction are arranged on the frame; 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] Preferably, the right end of the material gathering plate is rotatably connected to the frame, and a receiving groove is opened on the left side of the frame. A spring is fixedly connected in the receiving groove to support the left end of the material gathering plate. When the material gathering plate is not subjected to external force, the spring pushes the left end of the material gathering plate against the top of the receiving groove, and the material gathering plate is in a state of tilting downward from left to right.

[0015] By setting spring one, the left end of the gathering plate is supported so that the gathering plate can remain in an inclined state. At the same time, when the driving component three drives the gathering plate to rotate, the gathering plate can overcome the elastic force of the spring and move to a horizontal state, thereby preventing the gathering plate from affecting the flattening of the steel bars.

[0016] Preferably, the driving component three includes a driving member and a pulling block. A through slot extending in the left-right direction is opened on the frame. The pulling block is slidably arranged in the through slot. A fixed plate is fixedly connected to the bottom of the material gathering plate near the right end. A pulling plate is extended upward from the top of the pulling block. The pulling plate is located on the left side of the fixed plate. When the driving member drives the pulling block to move to the right, the pulling plate pushes the fixed plate to drive the material gathering plate to rotate downward.

[0017] Preferably, the pull block is slidably connected to the limit block in the vertical direction, and the limit block is elastically connected to the pull block through the second spring. When the left end of the material gathering plate abuts against the top of the accommodating groove, the limit block is located in the through groove, and the second spring is in a stretched state; The driving member is connected with the limit block through the limit structure 1. The driving member pulls the limit block and the pull block to the right through the limit structure 1. When the limit block is out of the accommodating groove, the spring 2 drives the limit block to move downward. The limit block rests on the frame. The limit structure 1 cancels the connection between the driving member and the limit block, and the gathering plate is in a horizontal state.

[0018] By setting a limit block, when the driving member drives the pull block to move rightward until the limit block is out of the through slot, the limit block can move downward to cooperate with the frame to limit the current position of the pull block without the driving member continuing to act on the pull block.

[0019] Preferably, the limiting structure comprises a mounting plate and a mounting rod fixedly connected to the mounting plate, a stopper and an L-shaped push block are fixedly connected to the bottom of the mounting rod, and an inclined wedge surface is provided on the right side of the limit block near the bottom, and the limit block is located between the stopper and the L-shaped push block when in the through slot, and during the rightward movement of the mounting plate, the stopper pulls the limit block and the pull block to move rightward, and the limit block is disengaged from the stopper when the limit block moves outside the through slot, and during the leftward movement of the mounting plate, the lateral part of the L-shaped push block squeezes the inclined wedge surface to drive the limit block to move upward until the limit block is disengaged from the contact with the right side wall of the frame, and the limit block follows the mounting rod into the through slot.

[0020] Preferably, the driving member includes a threaded section arranged on the rotating shaft and a limit rod cooperating with the threaded section, the mounting plate slidably cooperates with the two adjacent rotating shafts in the left and right directions, the threaded section is arranged on one of the rotating shafts, the limit rod vertically penetrates the mounting plate, the top of the limit rod is fixedly connected to the limit cap, the connecting plate is fixedly connected with a lifting structure, and the frame is fixedly connected with a limit structure 2. During the rightward movement of the feed roller, the lifting structure lifts the limit rod to make the limit rod break away from the contact with the threaded section, and the connecting plate pushes the mounting plate to move to the right. When the feed roller moves to the left, the limit structure 2 limits the mounting plate to follow the connecting plate. The lifting structure cancels the lifting of the limit rod, and the limit rod falls into the threaded section. When the rotating shaft rotates, the mounting plate is driven to move to the left through the cooperation of the threaded section and the limit rod.

[0021] Preferably, the second limiting structure includes a connecting rod fixedly connected to the frame, a baffle plate fixedly connected to the bottom of the connecting rod, a protrusion extending from the right side of the mounting plate, a spring block elastically connected to the top of the protrusion, and inclined planes 1 are respectively provided on the left and right sides of the spring block. When the mounting plate moves to the right until the spring block contacts the baffle plate, the baffle plate squeezes inclined plane 1 on the right side to make the spring block move downward. When the mounting plate moves to the left, the baffle plate squeezes inclined plane 1 on the left side to make the spring block move downward. The lifting structure includes a lifting plate symmetrically arranged on the connecting plate front and back, a second inclined plane and a flat surface are provided on the top of the lifting plate. When the limiting rod is located in the threaded section, the lifting plate pushes the limiting cap through the second inclined plane to make the limiting rod move upward.

[0022] The beneficial effects of the present invention are as follows: the present invention realizes automatic paving and arranging of steel bars, so that the steel bars entering under the cutter are arranged neatly, which is not only conducive to smooth feeding and shearing, but also eliminates the need for manual coordination to arrange the steel bars, thus saving labor and improving work efficiency.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 10As shown, a steel bar shearing device of the present invention comprises a frame 1, a cutting knife mechanism and a feeding mechanism arranged on the frame 1. The feeding mechanism is used to feed steel bars to the cutting knife mechanism, and the feeding direction of the feeding mechanism is defined as the front. The cutting knife mechanism comprises a mounting frame 11 mounted on the frame 1 and a cutting knife (not shown in the figure) connected to the mounting frame 11 along a vertical sliding manner. The mounting frame 11 is provided with an electric push rod 12 for driving the cutting knife to move up and down. A pressing mechanism is also arranged at the rear of the cutting knife mechanism, and the pressing mechanism comprises an electric push rod 2 13 mounted on the mounting frame 11 and a pressing plate 14 fixedly connected to the driving end of the electric push rod 2 13. The electric push rod 2 13 drives the pressing plate 14 to press the steel bars on the frame 1 downward to ensure the stability of the steel bars when being cut by the cutting knife, and to avoid the shaking of the steel bars during the shearing process, resulting in problems such as uneven steel bar cuts.

[0036] The feeding mechanism includes a feeding roller 2 and a gathering plate 3. The feeding rollers 2 are spaced apart in the front-to-back direction, and a plurality of feeding grooves 21 are evenly spaced apart on the outer circumference of the feeding roller 2 in the left-to-right direction. The frame 1 is provided with a driving component 1 for driving the feeding roller 2 to rotate and a driving component 2 for driving the feeding roller 2 to move in the left-to-right direction. The gathering plate 3 is spaced apart in the front-to-back direction, and the right end of the gathering plate 3 is rotatably connected to the frame 1. The frame 1 is provided with a driving component 3 for driving the gathering plate 3 to rotate.

[0037] like Figures 1 to 4 As shown, when the steel bars are conveyed to the feed roller 2, the gathering plate 3 is tilted downward from left to right. Under the guidance of the gathering plate 3, the steel bars will gather at a position near the right end of the feed roller 2. By controlling the drive component 3 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, the drive component 2 is controlled to drive the feed roller 2 to move to the right, so that the frame 1 pushes the steel bars gathered at the right end of the feed roller 2 to roll to the left and fall into the feed trough 21 on the feed roller 2, thereby achieving the flattening of the steel bars and avoiding the problem of unsmooth feeding caused by the accumulation of steel bars. In this embodiment, the left end of the feed roller 2 is fixedly connected with a stop plate 22 to prevent the accumulated steel bars from falling from the feed roller 2 when rolling to the left. Then, the drive component 1 is controlled to drive the feed roller 2 to rotate, and the feed roller 2 conveys the neatly arranged steel bars to the bottom of the cutter for shearing, avoiding the problem of large shear resistance caused by the accumulation of steel bars, or even the problem of failure to shear smoothly.

[0038] The present invention realizes automatic paving and arranging of steel bars, so that the steel bars entering under the cutter are arranged neatly, which is not only conducive to smooth feeding and shearing, but also eliminates the need for manual coordination to arrange the steel bars, thus saving labor and improving work efficiency.

[0039] Continue reading Figure 1The driving assembly 1 includes a rotating shaft 8 rotatably connected to the frame 1 and a motor 15 driving the rotating shaft 8 to rotate. The number of the rotating shafts 8 corresponds to the number of the feeding rollers 2, and the feeding rollers 2 are connected to the corresponding rotating shafts 8 and are coaxially arranged. Each rotating shaft 8 is fixedly connected to 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 to one of the rotating shafts 8. The motor 15 drives the rotating shaft 8 connected thereto to rotate, and the rotating shaft 8 drives the other rotating shafts 8 to rotate synchronously through the cooperation of the transmission wheel 82 and the transmission belt 83, thereby driving all the feeding rollers 2 to rotate synchronously and realizing the synchronous transportation of the steel bars.

[0040] like Figure 1 and Figure 7 As shown, the feed roller 2 is sleeved on the outer periphery of the rotating shaft 8, and a convex strip (not shown in the figure) extending along the axial direction of the rotating shaft 8 is fixedly connected to the rotating shaft 8, and a slide groove (not shown in the figure) adapted to the convex strip is opened in the feed roller 2. The feed roller 2 is slidably connected with the rotating shaft 8 along the left and right directions through the cooperation of the slide groove and the convex strip, so that the feed 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 component includes an electric push rod 3 90 fixedly mounted on the frame 1 and a sleeve 23 slidably connected to the rotating shaft 8. The sleeve 23 is rotatably connected to the corresponding feed roller 2, and the sleeves 23 on each rotating shaft 8 are fixedly connected through a connecting plate 9. The driving end of the electric push rod 3 90 is fixedly connected to the connecting plate 9, and the electric push rod 3 90 drives the connecting plate 9 to drive each sleeve 23 and the feed roller 2 to move left and right.

[0041] like Figure 4 As shown, a receiving groove 31 is opened on the left side of the frame 1, and a spring 32 supporting the left end of the gathering plate 3 is fixedly connected in the receiving groove 31. When the gathering plate 3 is not subjected to external force, the spring 32 pushes the left end of the gathering plate 3 against the top of the receiving groove 31, and the gathering plate 3 is in a state of tilting downward from left to right.

[0042] The driving assembly 3 includes a driving member and a pulling block 4. A through slot 16 extending in the left-right direction is provided on the frame 1. The pulling block 4 is slidably arranged in the through slot 16. A fixed plate 33 is fixedly connected to the bottom of the material gathering plate 3 near the right end. A pulling plate 41 extends upward from the top of the pulling block 4. The pulling plate 41 is located on the left side of the fixed plate 33. When the driving member drives the pulling block 4 to move rightward, the pulling plate 41 pushes the fixed plate 33 to drive the material gathering plate 3 to rotate downward.

[0043] like Figure 4 and Figure 5As shown, the pull block 4 is slidably connected to the limit block 42 in the vertical direction, and the limit block 42 is elastically connected to the pull block 4 through the spring 2 (not shown in the figure). When the left end of the material gathering plate 3 abuts against the top of the accommodating groove 31, the limit block 42 is located in the through groove 16, the spring 2 is in a stretched state, and the bottom of the limit block 42 is tightly against the bottom of the through groove 16. When the driving member drives the pull block 4 to move rightward until the limit block 42 is separated from the through groove 16, the limit block 42 moves downward under the elastic force of the spring 2, and the material gathering plate 3 rotates to a horizontal state. At this time, even if the material gathering plate 3 has a tendency to rotate upward under the push of the spring 1 32, the pull block 4 cannot move to the left along the through groove 16 because the limit block 42 abuts against the right side of the frame 1, and the material gathering plate 3 can only maintain the current state. Through the cooperation of the limit block 42 and the frame 1, the position of the pull block 4 is limited, and there is no need for the driving member to continue to act on the pull block 4.

[0044] like Figure 5 and Figure 6 As shown, the driving member is connected with the limit block 42 through the limit structure 1, and the limit structure 1 includes a mounting plate 5 and a mounting rod 51 fixedly connected to the left side of the mounting plate 5, and a stopper 52 and an L-shaped push block 53 are fixedly connected to the bottom of the mounting rod 51. An inclined wedge surface 43 is provided on the right side of the limit block 42 near the bottom.

[0045] When the limit block 42 is in the through groove 16, it is located between the stop block 52 and the L-shaped push block 53. During the movement of the mounting plate 5 to the right, the stop block 52 pulls the limit block 42 and the pull block 4 to move to the right. When the limit block 42 moves to the outside of the through groove 16, it moves downward under the action of the spring 2 and disengages from the stop block 52, canceling the connection between the pull block 4 and the mounting rod 51, completing the pulling of the aggregation plate 3 and keeping the aggregation plate 3 in a horizontal state.

[0046] like Figure 4 , Fig. 9 and Fig.10 As shown, when it is necessary to release the restriction of the limit block 42 on the position of the pull block 4, the mounting plate 5 moves to the left, and the lateral part of the L-shaped push block 53 will squeeze the inclined wedge surface 43 on the limit block 42, so that the limit block 42 moves upward and breaks away from the abutment with the frame 1. The limit block 42 enters between the stop block 52 and the L-shaped push block 53, and follows the movement of the mounting plate 5 into the through groove 16. The pull block 4 drives the pull plate 41 to move to the left, and the gathering plate 3 is pushed upward by the spring 32 to return to the state of tilting downward from left to right.

[0047] like Figure 2 , Figures 6 to 8As shown, the driving member includes a threaded section 81 disposed on the rotating shaft 8 and a limiting rod 6 matched with the threaded section 81. The mounting plate 5 is slidably matched with two adjacent rotating shafts 8 in the left-right direction, and the threaded section 81 is disposed on one of the rotating shafts 8. The limiting rod 6 vertically penetrates the mounting plate 5, and the top of the limiting rod 6 is fixedly connected to a limiting cap 61.

[0048] The connecting plate 9 is fixedly connected with a lifting structure, the mounting plate 5 is located on the right side of the connecting plate 9, and the lifting structure includes a lifting plate 91 symmetrically arranged on the right side of the connecting plate 9, and a space for accommodating the limit rod 6 is formed between the two lifting plates 91. Figure 4 As shown, a flat surface 92 and a second inclined surface 93 are provided on the top of the lifting plate 91, and the second inclined surface 93 is inclined downward from left to right.

[0049] Continue reading Figures 6 to 8 A limiting structure 2 is fixedly connected to the frame 1, and the limiting structure 2 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 protrusion 54 extends from the right side of the mounting plate 5. A mounting groove is provided on the top of the protrusion 54. A spring block 55 is elastically connected in the mounting groove. An inclined surface 56 is respectively provided on the left and right sides of the spring block 55. The inclined surface 56 on the left side of the spring block 55 is inclined upward from left to right, and the inclined surface 56 on the right side of the spring block 55 is inclined downward from left to right.

[0050] When the steel bars gather on the feed roller 2 near the right end, it is necessary to rotate the gathering plate 3 to a horizontal state and pull the feed roller 2 to move to the right. At this time, the limit block 42 on the pulling block 4 is located in the through groove 16 and connected to the mounting rod 51, the limit cap 61 is located on the flat surface 92 of the lifting plate 91, and the bottom end of the limit rod 6 does not contact the threaded section 81.

[0051] When the connecting plate 9 and the feeding roller 2 are pulled to the right by the electric push rod 3 90, the connecting plate 9 pushes the mounting plate 5 to move to the right, and the mounting plate 5 drives the pulling block 4 to move to the right through the cooperation of the stop block 52 and the limit block 42, so that the pulling plate 41 on the pulling block 4 cooperates with the fixed plate 33 on the gathering plate 3, and the gathering plate 3 is rotated to a horizontal state. When the limit block 42 moves to the outside of the through groove 16, it is disconnected from the mounting rod 51, and the connecting plate 9 continues to push the mounting plate 5 to move to the right. When the spring block 55 on the protrusion 54 contacts the baffle 71, the baffle 71 squeezes the inclined surface 56 on the right side of the spring block 55, so that the spring block 55 moves downward, and the spring block 55 pops out after passing over the baffle 71.

[0052] After the steel bars on the feed roller 2 are spread flat into the feed trough 21, it is necessary to drive the feed roller 2 to move to the left so as to transport the steel bars to the cutting mechanism. During the process of the electric push rod 3 90 driving the connecting plate 9 and the feed roller 2 to move to the left, the mounting plate 5 cannot move with the connecting plate 9 due to the blocking effect of the baffle 71 and the spring block 55. The limit cap 61 detaches from the lifting plate 91, and the limit rod 6 falls into the threaded section 81.

[0053] After the feed roller 2 moves to the left and reaches the position, the feed roller 2 is driven to rotate and feed the material. At this time, the rotating shaft 8 drives the mounting plate 5 to move to the left through the cooperation of the threaded section 81 and the limit rod 6. The baffle 71 squeezes the inclined surface 56 on the left side of the spring block 55, so that the spring block 55 moves downward, and the baffle 71 removes the blocking of the spring block 55. After the steel bar is sent to the cutting mechanism, the L-shaped push block 53 on the mounting plate 5 pushes the limit block 42 to move upward, and pushes the limit block 42 and the pull block 4 to move to the left. , the limit on the gathering plate 3 is cancelled, and the gathering plate 3 resumes the inclined state under the action of the spring 1 32. In the process of the mounting plate 5 moving to the left, the limit cap 61 contacts the lifting plate 91 on the connecting plate 9 and moves upward along the inclined surface 2 93 on the lifting plate 91. When the limit cap 61 moves to the flat surface 92 of the lifting plate 91, the bottom end of the limit rod 6 escapes from the threaded section 81, preparing for the mounting plate 5 to follow the connecting plate 9 to move to the right when the steel bars are laid flat next time.
