Description

Technical Field

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

[0002] Steel bars refer to steel materials used for reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, and sometimes square with rounded corners, including plain round bars, ribbed bars, and twisted bars. Steel bars play a major load-bearing role in buildings and are one of the essential materials in building construction. When carrying out building construction, the steel bars straightened by a straightening machine need to be further cut into the required lengths.

[0003] When cutting steel bars, generally, the spacing of the area where the steel bars pass through is first adjusted to be slightly larger than the diameter of the steel bars to improve the stability during the steel bar cutting process. After the steel bars are cut, it is necessary for workers to manually remove the cut steel bar parts from the cutting station. During the large-scale cutting of steel bars, workers perform heavy physical labor, which is likely to cause worker fatigue and strain. This not only easily leads to misoperations and improper operations but also affects production efficiency and delays the production progress. Summary of the Invention

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0035] Example 1, referring to Figure 1-2 , which is the first embodiment of the present invention, provides a steel bar cutting device for building construction, including a frame body 1, a cutting machine 2 is installed on the frame body 1, a bracket 3 is connected to the rear end of the frame body 1, steel bars are placed on the frame body 1 and the bracket 3 together, support pallets 4 are symmetrically connected to the frame body 1 with respect to the cutting machine 2, a gap adjustment component is installed on the frame body 1, the gap adjustment component includes multiple groups of cylinders installed on the frame body 1, the output end of the cylinder is connected with a push plate, a fixing plate is connected to the position corresponding to the push plate on the frame body 1, a space with adjustable width is formed on the frame body 1 by the push plate and the fixing plate, the gap of this space is adjusted according to the diameter of the steel bar, the gap is slightly larger than the diameter of the steel bar, and the steel bar passes through this area to improve the stability during the movement and cutting of the steel bar.

[0036] Referring to Figure 1-4, a cutting auxiliary unit is also installed on the frame body 1; the cutting auxiliary unit includes a discharging component installed on the frame body 1, a pressing component installed on the discharging component, and a feeding and transporting component installed at the front end of the frame body 1; the front end of the steel bar is pressed and movably arranged on the feeding and transporting component; the discharging component includes a pin shaft 5, the cutting machine 2 and the frame body 1 are rotationally connected through the pin shaft 5, the discharging component further includes a support block 6 connected to the frame body 1, a transmission shaft 7 connected to one end of the pin shaft 5, a special-shaped driving disk 8 connected to the other end of the transmission shaft 7, a pneumatic transmission pipe 9 connected to the frame body 1, a pressurizing plug column 10 hermetically and slidably connected inside one end of the pneumatic transmission pipe 9, a discharging plug column 11 hermetically and slidably connected inside the other end of the pneumatic transmission pipe 9, and a pneumatic recovery component connected between the pneumatic transmission pipe 9 and the pressurizing plug column 10.

[0037] Referring to Figure 3-4 , a circular slow inlet is arranged on the special-shaped driving disk 8, and the top of the column end of the pressurizing plug column 10 is arranged in the slow inlet; the support block 6 is located between the gap adjusting component and the feeding and transporting component, the column ends of the pressurizing plug column 10 and the discharging plug column 11 are both arranged outside the pneumatic transmission pipe 9, the column end of the pressurizing plug column 10 is arranged corresponding to the position of the special-shaped driving disk 8, and the column end of the discharging plug column 11 is movably arranged between the support block 6 and the gap adjusting component.

[0038] Specifically, the steel bar on the frame body 1 is further supported by the support block 6. When the cutting machine 2 presses down, the pin shaft 5 drives the special-shaped driving disk 8 to rotate through the transmission shaft 7. During the process that the cutting machine 2 approaches and cuts the steel bar, the special-shaped driving disk 8 does not contact the column end of the pressurizing plug column 10 until the cutting machine 2 cuts the steel bar and then continues to press down. The special-shaped driving disk 8 then contacts the column end of the pressurizing plug column 10, pushing the pressurizing plug column 10 to move in the pneumatic transmission pipe 9 to compress the air, pushing the discharging plug column 11 upward, lifting one end of the cut steel bar upward, causing the steel bar to tilt and automatically slide off the cutting station on the frame body 1. When a certain number of steel bars to be cut are stacked on one side of the frame body 1, they are then transported onto the transport vehicle at one time, eliminating the need for manual removal of the steel bars after each cut, thus improving work efficiency.

[0039] Referring to Figure 4 , the pneumatic recovery component includes a reset ring 12 connected to the inner pipe wall of the pneumatic transmission pipe 9, and a reset member 13 installed between the reset ring 12 and the discharging plug column 11. The reset member 13 can be a spring; both ends of the pneumatic transmission pipe 9 are connected with pipe covers, and the column ends of the pressurizing plug column 10 and the discharging plug column 11 both movably penetrate through the pipe covers.

[0040] Specifically, when the special-shaped drive disk 8 applies a force to the pressure plug column 10 and the pressure plug column 10 moves within the pneumatic transmission tube 9, the air pressure inside the pneumatic transmission tube 9 increases, pushing the discharge plug column 11 upward and compressing the reset member 13 until the special-shaped drive disk 8 disengages from the pressure plug column 10. The compressed reset member 13 then pushes the discharge plug column 11 downward to reset, causing the pressure plug column 10 to also reset.

[0041] During use, place the steel bar to be cut on the frame body 1, the bracket 3, and the two support plates 4, and adjust the position of the steel bar so that the position to be cut on the surface of the steel bar is directly below the cutting machine 2. Then start the cutting machine 2 and press down. When the cutting machine 2 presses down, it drives the special-shaped drive disk 8 to rotate synchronously through the pin shaft 5 and the transmission shaft 7 until after the cutting machine 2 cuts the steel bar, the special-shaped drive disk 8 contacts and applies a force to the pressure plug column 10, pushing the pressure plug column 10 to compress the air inside the pneumatic transmission tube 9. The discharge plug column 11 compresses the reset member 13 and moves upward to push one end of the cut steel bar, causing the steel bar to tilt and automatically slide off the cutting station on the frame body 1. Then lift the cutting machine 2 upward, and the compressed reset member 13 pushes the discharge plug column 11 and the pressure plug column 10 to reset. Repeat this step. When a certain number of steel bars to be cut accumulate on one side of the frame body 1, carry them onto the transport vehicle at one time, eliminating the need for manual removal of the steel bars after each cut, improving work efficiency, and reducing the labor intensity of workers.

[0042] Example 2, referring to Figure 1-2 and Figure 5-6 , is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the pressing component includes a rubber rope 14 connected to the support plate 4 on the side close to the bracket 3. When the rubber rope 14 is not stressed, it is arc-shaped to allow the steel bar to pass through smoothly. A transmission auxiliary rope 15 is connected to the other end of the rubber rope 14, a transmission main board 16 is connected to the end of the transmission auxiliary rope 15, a movable pulley 17 is slidably arranged on the frame body 1, a fixed pulley 18 is connected to the frame body 1, a transmission disk 31 is sleeved on the shaft wall of the transmission shaft 7, a damping sliding component is installed between the frame body 1 and the movable pulley 17, and a transmission main rope 32 is connected between the transmission main board 16 and the transmission disk 31. The transmission main rope 32 is arranged to bypass the movable pulley 17 and the fixed pulley 18 in sequence.

[0043] Specifically, when the cutting machine 2 is pressed down, the pin shaft 5 drives the transmission disc 31 to rotate through the transmission shaft 7, and applies tension to the transmission main rope 32. After the transmission main rope 32 is stressed, it pulls the transmission main board 16 downward, and applies downward tension to the rubber rope 14 through the transmission auxiliary rope 15 until the rubber rope 14 is tightly clamped on the steel bar to be cut. As the cutting machine 2 continues to be pressed down, the transmission main rope 32 continues to be tightened by the transmission disc 31. Under the pressure of the transmission main rope 32, the movable pulley 17 compresses the damping sliding component, so that the movable pulley 17 slides to the side of the fixed pulley 18, so that the rubber rope 14 is no longer stretched while meeting the rotation requirement of the transmission disc 31 until the cutting is completed;

[0044] When the cutting machine 2 is cutting the steel bars, the steel bars are automatically clamped, thereby improving the stability during the steel bar cutting process.

[0045] Reference Figure 6 The damping sliding assembly includes a damping frame 19 symmetrically connected to the frame body 1 about the movable pulley 17, a transmission block 20 slidably sleeved on the damping frame 19, a damping member 21 connected between the damping frame 19 and the transmission block 20, the damping member 21 can be a spring, and the transmission block 20 is arranged on the side wall of the movable pulley 17.

[0046] Specifically, when the movable pulley 17 is forced to move toward the fixed pulley 18, the movable pulley 17 compresses the damping member 21 through the transmission block 20 and slides on the damping frame 19, thereby driving the movable pulley 17 to move synchronously until the movable pulley 17 loses the pulling force, and the compressed damping member 21 pushes the transmission block 20 and the movable pulley 17 to reset.

[0047] Reference Figure 1-3 The two side walls of the transmission main board 16 are connected to the limit blocks 30, and the position corresponding to the limit blocks 30 on the frame body 1 is connected to the limit shaft 22, and the limit shaft 22 movably penetrates the corresponding limit block 30. A push-up member 33 is commonly connected between the frame body 1 and the limit block 30. The push-up member 33 can be a spring, and the force required for the deformation of the push-up member 33 is less than the force required for the deformation of the damping member 21.

[0048] Specifically, through the limit block 30 on the limit shaft 22, the transmission main board 16 can only move in the vertical direction, and when the transmission main board 16 descends, the transmission main board 16 will compress the push-up piece 33 through the limit block 30; the cutting machine 2 is lifted upward, the transmission disk 31 gradually loosens the tightened transmission main rope 32, the damping sliding assembly first pushes the movable pulley 17 to reset, and the push-up piece 33 pushes the transmission main board 16 and the rubber rope 14 to reset.

[0049] When the cutting machine 2 is in use, the pin shaft 5 drives the transmission plate 31 to rotate through the transmission shaft 7, and the transmission main rope 32 pulls the transmission main board 16 down, and the transmission main board 16 drives the limit block 30 to compress the upper push piece 33, and exerts a downward pulling force on the rubber rope 14 through the transmission auxiliary rope 15, so that the rubber rope 14 is tightly clamped on the steel bar to be cut, and the steel bar on the supporting support plate 4 is limited. As the cutting machine 2 continues to be pressed down, the main transmission rope 32 exerts a pushing force on the movable pulley 17, and the movable pulley 17 drives the transmission block 20 to compress the damping member 21 and slide to one side of the fixed pulley 18, so that the rubber rope 14 is no longer stretched while meeting the rotation requirement of the transmission plate 31. Until the cutting is completed, the cutting machine 2 is lifted up again, and under the action of the upper push piece 33 and the damping member 21, the pressing components are reset in sequence, and the rubber rope 14 releases the fixation of the steel bar, so that the residual steel bar on the frame body 1 and the bracket 3 can move normally;

[0050] When the cutting machine 2 is cutting the steel bars, the steel bars are automatically clamped, which improves the stability during the steel bar cutting process. When the steel bar cutting is completed, the steel bars are automatically released.

[0051] The remaining structures are the same as those of Example 1.

[0052] Example 3, reference Figure 1-8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the top material transportation component includes a conveyor belt 23 installed on the frame body 1, an auxiliary column 24 connected to the front end of the frame body 1, a sleeve 25 slidably sleeved on the auxiliary column 24, a support seat 26 connected to one end of the sleeve 25 close to the steel bar, a button groove corresponding to the position of the steel bar is opened on the support seat 26, a self-resetting push-type start button 27 installed in the button groove, and a positioning component installed on the sleeve 25 and the auxiliary column 24, the self-resetting push-type start button 27 and the conveyor belt 23 are controlled and connected by a wire, the steel bar is movably arranged on the conveyor belt 23, the self-resetting push-type start button 27 is pressed and started by the top pressure of the steel bar, and after the self-resetting push-type start button 27 is pressed, the starting end is flush with the side of the support seat 26 close to the frame body 1, and the cutting machine 2 and the conveyor belt 23 are powered by an external power supply.

[0053] Specifically, the steel bars are placed on the conveyor belt 23, and the conveyor belt 23 drives the steel bars to move. The steel bars touch and press the self-resetting push-type start button 27. After the self-resetting push-type start button 27 is activated, the conveyor belt 23 is automatically powered off and the steel bars stop moving; until the cut part of the steel bars is lifted up from the rack body 1 and slides off the rack body 1, the self-resetting push-type start button 27 loses the pressing and resetting function and resets itself out of the button slot, and the conveyor belt 23 continues to be powered on to transport the steel bars.

[0054] Reference Figure 1-3, the positioning component includes a scale value 28 provided on the auxiliary column 24 and positioning bolts 29 provided on the sleeve 25 and the auxiliary column 24.

[0055] Specifically, by adjusting the position of the sleeve 25 on the auxiliary column 24, the position of the support base 26 is adjusted, and then the sleeve 25 is locked by the positioning bolt 29 to fix the position of the support base 26. Since the distance between the cutting position of the cutting machine 2 and the starting end of the scale value 28 is constant, the distance between the support base 26 and the cutting machine 2 can be clearly known in cooperation with the scale value 28, thereby limiting the distance of the cut steel bar.

[0056] During use, first adjust the position of the sleeve 25 on the auxiliary column 24 according to the length of the required steel bar and lock it with the positioning bolt 29. Then place the steel bar on the frame body 1 and the conveyor belt 23. Subsequently, turn on the external power supply. At this time, the self-resetting push-button start button 27 is not pressed, and the conveyor belt 23 is in the energized state. Push the steel bar forward until it presses the self-resetting push-button start button 27, then the conveyor belt 23 automatically cuts off the power. Then cut the steel bar with the cutting machine 2. After cutting is completed, the cut steel bar is automatically ejected. Subsequently, the self-resetting push-button start button 27 resets, and the conveyor belt 23 continues to convey the steel bar forward. A relay can be added. When the self-resetting push-button start button 27 is in the energized state, the conveyor belt 23 starts with a delay;

[0057] After each cutting is completed, the steel bar is automatically transported and moved forward without manual handling, reducing the labor intensity of workers. Moreover, after the steel bar moves into place, the conveyor belt 23 automatically closes to prevent unnecessary wear on the conveyor belt 23 caused by the steel bar.

[0058] The remaining structure is the same as that of Embodiment 2.

[0059] Combining Embodiments 1-3, the working principle of the present invention is as follows: First, adjust the position of the sleeve 25 on the auxiliary column 24 according to the length of the required steel bar and lock it with the positioning bolt 29. Then adjust the gap adjustment component so that the distance is slightly larger than the diameter of the steel bar. Subsequently, place the steel bar on the frame body 1, the bracket 3 and the conveyor belt 23, turn on the external power supply, and the conveyor belt 23 is started to push the steel bar forward until it presses the self-resetting push-button start button 27, then the conveyor belt 23 automatically cuts off the power.

[0060] Start the cutting machine 2 and press downward, the pin shaft 5 drives the special-shaped driving disk 8 and the transmission disk 31 to rotate through the transmission shaft 7, and the transmission main board 16 is pulled down by the transmission main rope 32. The transmission main board 16 drives the limit block 30 to compress the push-up member 33, and applies a downward pulling force to the rubber rope 14 through the transmission auxiliary rope 15, so that the rubber rope 14 is tightly clamped on the steel bar to be cut, and the steel bar on the support plate 4 is limited. As the cutting machine 2 continues to be pressed downward, the transmission main rope 32 applies a driving force to the movable pulley 17, and the movable pulley 17 drives the transmission block 20 to compress the damping member 21 and slide to the side of the fixed pulley 18, so that the rubber rope 14 is no longer stretched while meeting the rotation requirement of the transmission disk 31. While the cutting machine 2 is pressed downward, the transmission shaft 7 also drives the special-shaped driving disk 8 to rotate synchronously.

[0061] After the cutting machine 2 cuts the steel bar, as the cutting machine 2 continues to be pressed down, the special-shaped driving disk 8 contacts and applies force to the pressurized plug 10, pushing the pressurized plug 10 to compress the air in the pneumatic transmission tube 9, and the unloading plug 11 compresses the reset part 13 to move upward to push one end of the cut steel bar, and the steel bar tilts and automatically slides to the cutting station on the frame body 1. Then the cutting machine 2 is lifted up, and the compressed reset part 13 pushes the unloading plug 11 and the pressurized plug 10 to reset. At the same time, under the action of the push-up part 33 and the damping part 21, the clamping parts are reset in turn, and the rubber rope 14 releases the fixation of the steel bar.

[0062] When the steel bar slides down the cutting station on the frame body 1, the self-resetting push-type start button 27 is no longer pressed, and the conveyor belt 23 continues to convey the steel bar forward until the steel bar presses the self-resetting push-type start button 27, and the conveyor belt 23 is powered off to carry out the next round of cutting. When a certain number of steel bars to be cut are accumulated on one side of the frame body 1, they are transported to the transport vehicle at one time, and there is no need to manually remove the steel bars after each cutting, thereby improving work efficiency.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
