Description

Technical Field

[0001] The invention belongs to the field of cutting equipment, in particular to a fast cutting equipment for steel bars of equal length. Background Art

[0002] Rebar is an important building material, mainly used in reinforced concrete structures to enhance the tensile properties of concrete. During the construction process, the cutting of rebar is an indispensable link. Due to the complexity and diversity of building structures, the rebar needs to be cut and adjusted according to actual conditions to ensure the smooth progress of construction. By cutting with equal length, it can be ensured that the length of each section of rebar is consistent, which is crucial to ensure the overall stability and strength of the structure.

[0003] The invention patent with announcement number CN107813015A discloses a mechanical steel bar equal length cutting device. The technical problem to be solved by the invention is to provide a mechanical steel bar equal length cutting device that does not require human hands. In order to solve the above technical problems, the invention provides such a mechanical steel bar equal length cutting device, including a bottom plate, a first support rod, a roller, a first transmission bar, a second support rod, a guide sleeve, a third support rod, etc.; the first support rods are connected to the left and right sides of the upper side of the bottom plate, and the two first support rods are rotatably connected to the upper front sides of the two first support rods. A first transmission bar is connected between the two rollers, and steel bars are placed on the first transmission bar. The second support rod is connected to the left side of the upper side of the bottom plate. The invention achieves the effect of equal length cutting without human hands. The second motor drives the first motor and the saw blade to move downward to cut the steel bar, so that people do not need to hold the electric saw to cut, reducing the possibility of harm to users.

[0004] However, the above technical solution still has the following deficiencies in practical application: When the steel bar is cut, debris will be generated. These debris will splash to the surroundings, which not only pollutes the working environment, but also increases the difficulty of cleaning. Moreover, if the debris splashes onto the machine, it may cause wear or damage to the machine, thereby shortening the service life of the machine. Moreover, these debris will splash to parts of the steel bar other than the cutting part, causing the appearance quality of the steel bar to be affected, thereby affecting the smooth progress of subsequent steel bar processing operations. For example, before spraying the anti-corrosion coating on the steel bar, the surface of the steel bar needs to be cleaned to keep it clean. If the debris splashed onto the surface of the steel bar during the cutting process is relatively scattered, it will increase the difficulty of cleaning the steel bar, which is not conducive to the processing operation.

During the construction process, steel bar cutting is an indispensable link. Due to the complexity and diversity of building structures, steel bars need to be cut and adjusted according to actual conditions to ensure the smooth progress of construction. By cutting the steel bars in equal length, the length of each section of steel bars can be ensured to be consistent, which is essential to ensure the overall stability and strength of the structure. During the use of existing steel bar equal length cutting equipment, when the steel bars are cut, debris will be generated. These debris will splash to the surrounding area, which not only pollutes the working environment, but also increases the difficulty of cleaning. Moreover, if the debris splashes onto the machine, it may cause wear or damage to the machine, thereby shortening the service life of the machine. Moreover, these debris will splash onto the parts of the steel bars other than the cutting part, resulting in the appearance quality of the steel bars being affected, thereby affecting the smooth progress of subsequent steel bar processing operations. For example, before spraying the anti-corrosion coating on the steel bars, the surface of the steel bars needs to be cleaned to keep it clean. If the debris splashed onto the surface of the steel bars is relatively scattered during the cutting process, it will increase the difficulty of cleaning the steel bars, which is not conducive to the processing operation. Therefore, in order to solve the above problems, when the present embodiment is in use, when the steel bar is being cut, it will pass through the axis of the two shells 20, and then the motor 6 42 is started to drive the bidirectional threaded rod 10 to rotate, so that the frame 8 on both sides slides and approaches each other at the same time, so that the shells 20 on both sides approach each other until they fit together, and then according to the diameter of the steel bar, the motors 4 22 on both sides are started at the same time, and the motors 4 22 drive the gear 24 on one side to rotate, and with the cooperation of the gear ring 23, multiple gears 24 rotate at the same time, and when the gear 24 rotates, multiple aggregation blocks 45 slide at the same time, so that the aggregation blocks 45 are close to the steel bar, and at the same time, the rectangular area formed by the multiple aggregation blocks 45 becomes smaller, so that the aggregation blocks 45 are as close to the steel bar as possible without touching the surface of the steel bar, and when the saw blade 41 descends, the closing block 39 will fit with the groove above the shell 20, The opening at the upper end of the shell 20 is blocked, and most of the debris in the cutting process will be intercepted in the cavity formed by the two shells 20. In addition, since the distance between the polymer block 45 and the steel bar is small, the amount of debris splashing out from the rectangular hole of the shell 20 is reduced. In addition, since the dust suction port 26 faces downward, under the action of the exhaust fan 43, a small amount of debris splashing from the rectangular hole is sucked in and enters the dust collecting box 44 after passing through the hard tube 25 and the hose 9, which can largely avoid the debris splashing to the surrounding area, protect the working environment, reduce the difficulty of cleaning, and avoid the debris splashing onto the machine, causing wear or damage to the machine, thereby shortening the service life of the machine. In addition, it also avoids the debris splashing to the parts of the steel bar other than the cutting part, reducing the difficulty of cleaning the debris on the surface of the steel bar for subsequent processing; When the steel bar is cut, the rectangular hole of the shell 20 is regarded as the middle part. If the steel bar on the left side of the rectangular hole is longer than the steel bar on the right side of the rectangular hole, the cut steel bar will fall onto the aggregation block 45 and tilt to the left, and fall into the collection box 2 with the blanking plate 30. If the steel bar on the right side of the rectangular hole is longer than the steel bar on the left side of the rectangular hole, the cut steel bar will tilt to the right, and then the cut steel bar cannot fall normally into the collection box 2 for collection, and will be stuck in the inner cavity of the shell 20, affecting the subsequent cutting work. Therefore, when the steel bar is cut, the electric push rod 28 will drive the lifting block 31 to rise, so that the steel bar on the right side of the rectangular hole is lifted, which can make the steel bar tilt to the left again, so that the steel bar can fall from the blanking plate 30 to the collection box 2, which can avoid the situation that the steel bar tilts to the right when it is cut and cannot fall normally, thereby ensuring the smooth progress of the subsequent cutting work; After the shell 20 has been used for a period of time, a certain amount of debris will still adhere to its inner wall. In order to prevent the debris from falling through the inner wall of the shell 20 to the surface of the subsequent steel bar, thereby causing repeated contamination of the debris, the two shells 20 can be driven to separate after a whole steel bar is cut to equal length, and then the motor 3 18 is started to drive the shell 20 to rotate 90 degrees, so that the opening of the shell 20 faces downward, and then the motor 2 14 is started to drive the connecting rod 1 15 to rotate. Under the action of the connecting rod 2 16, the mounting plate 17 moves back and forth up and down, and the sliding rod 2 12 slides back and forth in the inner cavity of the sleeve 11, so that the shell 20 can be shaken up and down, so that the debris attached to the inner cavity wall falls into the collection box 2 3, thereby realizing self-cleaning of the inner cavity wall of the shell 20, avoiding the debris from falling through the inner wall of the shell 20 to the surface of the subsequent steel bar to be cut, thereby causing repeated contamination of the debris, and further ensuring the surface quality of the steel bar; Therefore, by utilizing the auxiliary material-feeding anti-splash mechanism, the position of the aggregation block 45 can be adjusted according to the diameter of the steel bar, so that the aggregation block 45 can be as close to the steel bar as possible without affecting the movement and cutting of the steel bar. Then, with the cooperation of the aggregation block 45 and the shell 20, the cutting part of the steel bar can be enclosed to reduce the range of debris splashing to a large extent, thereby protecting the working environment, reducing the difficulty of cleaning, and preventing debris from splashing onto the machine, causing wear or damage to the machine, thereby shortening the service life of the machine. In addition, it also prevents debris from splashing onto parts of the steel bar other than the cutting part, reducing the difficulty of cleaning the debris on the surface of the steel bar for subsequent processing, and, After the steel bar is cut, the right side of the steel bar can be lifted so that the steel bar can fall smoothly into the collection box 2 through the blanking plate 30 under the action of gravity for collection, thereby preventing the steel bar from falling onto the aggregation block 45 and tilting to the right when being cut, and being unable to fall and be collected normally, thereby ensuring the smooth progress of subsequent cutting work; and, after a whole steel bar is cut to equal length, the shell 20 can be separated, and the debris attached to the inner wall can be shaken off, thereby realizing self-cleaning of the inner wall of the shell 20, thereby preventing the debris from falling through the inner wall of the shell 20 to the surface of the steel bar to be cut later, thereby causing repeated contamination of the debris, thereby further ensuring the surface quality of the steel bar.

[0026] Working principle: place one end of the steel bar to be cut between the two clamping blocks 35, then manually rotate the two-way threaded rod 2 33 to drive the two clamping blocks 35 to move simultaneously and approach each other, so that one end of the steel bar can be clamped, and then according to the required cutting length, start the motor 1 5 to drive the threaded rod 4 to rotate, so that the displacement plate 7 slides from right to left on the slide bar 1 6, so that the saw blade 41 is aligned with the position of the steel bar to be cut, and then stop moving the steel bar, and then start the electric push rod 2 37 and the motor 5 40 at the same time, the electric push rod 2 37 drives the closing block 39 to descend, the slide bar 5 38 slides on the frame 2 36, and the motor 5 40 drives the saw blade 41 to rotate, and then the steel bar can be cut. When cutting the steel bar, after cutting a section, continue to drive the steel bar to move, and the moving distance of the steel bar each time is certain, so that the steel bar can be cut at equal length. In addition, compared with manually holding the steel bar for equal length cutting, the process of measuring the cutting length is omitted, and the whole cutting process is relatively fast. When the steel bar is in the cutting process, it will pass through the axis of the two shells 20, and then start the motor six 42 to drive the bidirectional threaded rod one 10 to rotate, so that the frame one 8 on both sides slides at the same time and approaches each other, so that the shells 20 on both sides are close to each other until they fit together, and then according to the diameter of the steel bar, start the motor four 22 on both sides at the same time, and the motor four 22 drives The gear 24 on one side rotates, and with the cooperation of the gear ring 23, multiple gears 24 rotate at the same time. When the gear 24 rotates, multiple aggregation blocks 45 slide at the same time, so that the aggregation block 45 is close to the steel bar. At the same time, the rectangular area formed by the multiple aggregation blocks 45 becomes smaller, so that the aggregation block 45 is as close to the steel bar as possible without contacting the surface of the steel bar. When the saw blade 41 descends, the closing block 39 will fit into the groove above the shell 20, so that the opening at the upper end of the shell 20 is blocked, and most of the debris in the cutting process will be intercepted in the cavity formed by the two shells 20. In addition, since the distance between the aggregation block 45 and the steel bar is small, the friction between the aggregation block 45 and the steel bar is reduced. The number of debris splashing out from the rectangular hole of the housing 20 is reduced, and because the dust suction port 26 faces downward, a small amount of debris splashing out from the rectangular hole is sucked in by the exhaust fan 43, and enters the dust collecting box 44 after passing through the hard tube 25 and the hose 9, which can largely avoid the debris splashing to the surrounding area, protect the working environment, reduce the difficulty of cleaning, and avoid the debris splashing onto the machine, causing wear or damage to the machine, thereby shortening the service life of the machine. In addition, it also avoids the debris splashing to the parts of the steel bar other than the cutting part, reducing the difficulty of cleaning the debris on the surface of the steel bar for subsequent processing;When the steel bar is cut, the rectangular hole of the shell 20 is regarded as the middle part. If the steel bar on the left side of the rectangular hole is longer than the steel bar on the right side of the rectangular hole, the cut steel bar will fall onto the aggregation block 45 and tilt to the left, and fall into the collection box 2 with the blanking plate 30. If the steel bar on the right side of the rectangular hole is longer than the steel bar on the left side of the rectangular hole, the cut steel bar will tilt to the right, and the cut steel bar will not be able to fall normally into the collection box 2 for collection, and will be stuck in the inner cavity of the shell 20, affecting the subsequent cutting work. Therefore, when the steel bar is cut, the electric push rod 28 will drive the lifting block 31 to rise, so that the steel bar on the right side of the rectangular hole is lifted. The steel bar can be tilted to the left again, so that the steel bar can fall from the blanking plate 30 into the collection box 1 2, which can avoid the situation that the steel bar tilts to the right and cannot fall normally when being cut, thereby ensuring the smooth progress of subsequent cutting work; after the shell 20 has been used for a period of time, a certain amount of debris will still adhere to its inner wall. In order to prevent the debris from falling through the inner wall of the shell 20 to the surface of the subsequent steel bar, thereby causing repeated contamination of the debris, the two shells 20 can be driven to separate after an entire steel bar is cut to equal length, and then the motor three 18 is started to drive the shell 20 to rotate ninety degrees, so that the opening of the shell 20 faces downward, and then the motor two 14 is started to drive the connecting rod one 15 to rotate, and under the action of the connecting rod two 16 Under the action of the auxiliary material feeding type splash-proof mechanism, the position of the polymer block 45 can be adjusted according to the diameter of the steel bar, so that the polymer block 45 can be as close to the steel bar as possible without affecting the movement and cutting of the steel bar, and the steel bar can be cut at the cutting position with the cooperation of the polymer block 45 and the shell 20. The enclosure can greatly reduce the scope of debris splashing, protect the working environment, reduce the difficulty of cleaning, and avoid the debris splashing onto the machine, causing wear or damage to the machine, thereby shortening the service life of the machine. In addition, it also avoids the debris splashing to the parts of the steel bar other than the cutting part, reducing the difficulty of cleaning the debris on the surface of the steel bar for subsequent processing. In addition, after the steel bar is cut, the right side of the steel bar can be lifted so that the steel bar can fall smoothly into the collection box 2 through the blanking plate 30 under the action of gravity for collection, avoiding the situation that the steel bar falls onto the aggregation block 45 and tilts to the right when the steel bar is cut, and cannot be normally dropped and collected, thereby ensuring the smooth progress of subsequent cutting work;Moreover, after a whole steel bar is cut to equal length, the shell 20 can be separated and the debris attached to the inner wall can be shaken off, thereby realizing self-cleaning of the inner wall of the shell 20, avoiding the debris from falling through the inner wall of the shell 20 to the surface of the steel bar to be cut later, thereby causing repeated contamination of the debris, and further ensuring the surface quality of the steel bar. ;
