Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a steel bar cutting machine for construction. Background Technology

[0002] In building construction, steel bars need to be cut using a cutting machine. When steel bars need to be connected to components of different lengths (such as beams, columns, and slabs), they need to be cut into uniform lengths according to design requirements to ensure joint strength.

[0003] In the current technology, when cutting steel bars into multiple lengths, it is generally necessary to use a marker and a measuring tape to mark the surface of the steel bars, and then cut them one by one according to the marked positions, which is quite inconvenient. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a steel bar cutting machine for construction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a construction steel bar cutting machine, including a cutting table, a cutting groove is provided on the top of the cutting table, a cutting mechanism for cutting steel bars is provided on the cutting table, a placement groove extending to both sides of the cutting table is provided on the top of the cutting table, the cutting groove and the placement groove are connected, an L-shaped limiting seat is slidably provided on the cutting table, a discharge through hole is provided through the horizontal section of the limiting seat, and a displacement component for driving the limiting seat to move is provided on the cutting table.

[0006] By adopting the above technical solution, the reinforcing bar to be cut is first placed in the placement groove, with one end of the reinforcing bar aligned with the vertical section of the limiting seat. Then, the cutting mechanism cuts the reinforcing bar, and finally, the cut reinforcing bar is moved away from the limiting seat through the discharge hole. The displacement component moves the limiting seat, thereby adjusting the distance between the vertical section of the limiting seat and the cutting table, thus achieving the purpose of cutting reinforcing bars of various lengths. This eliminates the cumbersome operation of marking the surface of the reinforcing bar using a marker and measuring tape, as in existing technologies, making it easier for workers to use.

[0007] Furthermore, a threaded groove is provided on the side wall of the cutting table near the limiting seat. The displacement assembly includes a displacement screw rod that is rotatably connected to the limiting seat, a rotating wheel that is fixedly sleeved on the displacement screw rod, and an insert rod that is fixed on the cutting table. The displacement screw rod is inserted into the threaded groove and threadedly connected. The limiting seat is provided with an insertion hole that engages with the insert rod.

[0008] By adopting the above technical solution, the rotating wheel drives the displacement screw to rotate. Since the insertion rod and the insertion hole are connected, the displacement screw is threadedly connected to the threaded groove, thereby achieving the purpose of moving the limit seat.

[0009] Furthermore, the cutting mechanism includes a cutting assembly, which includes an L-shaped mounting bracket fixed to the top of the cutting table, an electric cutting saw mounted on the mounting bracket, and an electric hydraulic push rod mounted on the mounting bracket. The push rod end of the electric hydraulic push rod is fixedly connected to the electric cutting saw. The cutting saw on the electric cutting saw is located above the cutting groove. The cutting mechanism also includes a moving mechanism for driving the electric cutting saw to move.

[0010] By adopting the above technical solution, after the electric hydraulic push rod is working, its push rod end extends and retracts, which enables the electric cutting saw fixed to the push rod end of the electric hydraulic push rod to work, thereby achieving the purpose of cutting steel bars by the cutting saw on the electric cutting saw.

[0011] Furthermore, the horizontal section of the mounting frame is an annular structure, and the moving mechanism includes a motor fixed to the mounting frame, a slider slidably connected to the horizontal section of the mounting frame, and a moving screw rotatably installed in the horizontal section of the mounting frame and threadedly connected to the slider. The motor is used to drive the moving screw to rotate. The electro-hydraulic push rod is fixed to the slider, and the push rod end of the electro-hydraulic push rod passes through the slider and is slidably engaged. Multiple placement slots are provided, and the inner diameter of each placement slot is different.

[0012] By adopting the above technical solution, after the motor works, it drives the moving screw to rotate, which causes the slider threadedly connected to the moving screw, the electric hydraulic push rod fixed to the slider, and the electric cutting saw fixed to the push rod end of the electric hydraulic push rod to move, thereby adjusting the cutting distance position. Since there are multiple placement slots, each with a different inner diameter, it can be used with the electric cutting saw to cut steel bars of various diameters, thus expanding the applicability of the device.

[0013] Furthermore, the electric cutting saw is provided with a positioning component, which includes a fixed plate fixed to the electric cutting saw, a vertical rod that passes through the fixed plate and is slidably engaged, a clamping plate fixed to the lower end of the vertical rod, a limiting block fixed to the upper end of the vertical rod, and a spring fixed between the limiting block and the fixed plate. The distance between the bottom of the clamping plate and the top of the cutting table is less than the distance between the bottom of the cutting saw and the top of the cutting table.

[0014] By adopting the above technical solution, during the descent of the electric cutting saw, the fixed plate fixed to the electric cutting saw, the vertical rod connected to the fixed plate, the clamping plate connected to the vertical rod, the limiting block connected to the clamping plate, and the spring connected to the limiting block all descend. The clamping plate initially contacts the surface of the rebar and remains stationary. As the electric cutting saw continues to descend, the fixed plate continues to move, and the limiting block is gradually stretched until the cutting saw cuts the rebar. After cutting, the electric cutting saw rises and resets, causing the fixed plate fixed to the electric cutting saw, the vertical rod connected to the fixed plate, the clamping plate connected to the vertical rod, the limiting block connected to the clamping plate, and the spring connected to the limiting block to rise and reset, so that they can be used for the next cutting operation. The positioning components improve the stability during rebar cutting.

[0015] Furthermore, a horizontal plate is fixed on the limiting seat, an indicator needle is fixed at the upper end of the horizontal plate, and a scale line is provided on the side wall of the cutting table near the position of the indicator needle.

[0016] By adopting the above technical solution, the setting of the horizontal plate, indicator needle and scale line makes it easy to read the degree of the required cutting length. The length of the steel bar is equal to the distance between the vertical section of the limit seat and the middle of the cutting groove.

[0017] Furthermore, the vertical section of the limiting seat is provided with a limiting groove that communicates with the discharge through hole, and the number of limiting grooves is equal to the number of placement grooves and their positions correspond one-to-one.

[0018] By adopting the above technical solution and setting the limiting groove, the stability during steel bar cutting is improved.

[0019] In summary, this utility model has the following beneficial effects: In this application, by setting a limiting seat and a displacement component, the cumbersome operation of marking the surface of the steel bars with a marker and a measuring tape, as required by the prior art, is eliminated, making it easier for workers to use.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] like Figure 1-5 As shown in the illustration, this application discloses a rebar cutting machine for construction, including a cutting table 1, a displacement component 6, a cutting mechanism 3, and a positioning component 9. The top of the cutting table 1 has a cutting groove 2. Placement grooves 4 extending to both sides of the cutting table 1 are also provided on the top of the cutting table 1. A threaded groove 7 is provided on the side wall of the cutting table 1 near the limiting seat 5. The cutting groove 2 communicates with the placement groove 4. An L-shaped limiting seat 5 is slidably mounted on the cutting table 1, with a discharge through hole through its horizontal section. First, the rebar to be cut is placed in the placement groove 4, and one end of the rebar is aligned with the vertical section of the limiting seat 5. Then, the rebar is cut by the cutting mechanism 3. Finally, the cut rebar is removed from the limiting seat 5 through the discharge through hole. The displacement component 6 moves the limiting seat 5, thereby adjusting the distance between the vertical section of the limiting seat 5 and the cutting table 1, thus achieving the purpose of cutting rebar of various lengths. This eliminates the cumbersome operation of marking the surface of the rebar with a marker and measuring tape, as required by existing technologies, making it easier for workers to use.

[0024] The displacement assembly 6 is mounted on the cutting table 1 and is used to drive the limiting seat 5 to move. The displacement assembly 6 includes a displacement screw 61, a rotating wheel 62, and a insertion rod 63. The displacement screw 61 is inserted through and rotatably connected to the limiting seat 5. The displacement screw 61 is inserted into the threaded groove 7 and threadedly connected. The rotating wheel 62 is fixedly sleeved on the displacement screw 61. The insertion rod 63 is fixed to the cutting table 1, and the limiting seat 5 has a through-hole 8 for insertion and engagement with the insertion rod 63. Rotating the rotating wheel 62 drives the displacement screw 61 to rotate. Because the insertion rod 63 engages with the through-hole 8, the displacement screw 61 is threadedly connected to the threaded groove 7, thereby achieving the purpose of moving the limiting seat 5.

[0025] A cutting mechanism 3 is mounted on a cutting table 1 and is used to cut reinforcing bars. The cutting mechanism 3 includes a cutting assembly 31 and a moving mechanism 32. The cutting assembly 31 includes a mounting frame 311, an electric cutting saw 312, and an electric hydraulic push rod 313. The mounting frame 311 is fixed to the top of the cutting table 1 and has an L-shaped structure. The horizontal section of the mounting frame 311 is annular. The electric cutting saw 312 is mounted on the mounting frame 311. The cutting saw on the electric cutting saw 312 is located above the cutting groove 2. The electric hydraulic push rod 313 is mounted on the mounting frame 311, and the push rod end of the electric hydraulic push rod 313 is fixedly connected to the electric cutting saw 312. When the electric hydraulic push rod 313 operates, its push rod end extends or retracts, thereby enabling the electric cutting saw 312, which is fixed to the push rod end of the electric hydraulic push rod 313, to operate, thus achieving the purpose of cutting the reinforcing bars with the cutting saw on the electric cutting saw 312.

[0026] The moving mechanism 32 drives the electric cutting saw 312 to move. The moving mechanism 32 includes a motor 321, a slider 322, and a moving screw 323. The motor 321 is fixed to the mounting bracket 311 and drives the moving screw 323 to rotate. The slider 322 is slidably connected within the horizontal section of the mounting bracket 311, and an electro-hydraulic push rod 313 is fixed to the slider 322. The push rod end of the electro-hydraulic push rod 313 passes through the slider 322 and is slidably engaged. The moving screw 323 is rotatably mounted within the horizontal section of the mounting bracket 311 and threadedly connected to the slider 322. Multiple placement slots 4 are provided, each with a different inner diameter. After the motor 321 starts working, it drives the moving screw 323 to rotate, which causes the slider 322 threadedly connected to the moving screw 323, the electro-hydraulic push rod 313 fixed to the slider 322, and the electric cutting saw 312 fixed to the push rod end of the electro-hydraulic push rod 313 to move, thereby adjusting the cutting distance position. Since there are multiple placement slots 4, each with a different inner diameter, they can be used with the electric cutting saw 312 to cut steel bars of various diameters, thus expanding the applicability of the device.

[0027] The positioning component 9 is mounted on the electric cutting saw 312. The positioning component 9 includes a fixed plate 91, a vertical rod 92, a clamping plate 93, a limiting block 94, and a spring 95. The fixed plate 91 is fixed to the electric cutting saw 312, and the vertical rod 92 passes through the fixed plate 91 and slides within it. The clamping plate 93 is fixed to the lower end of the vertical rod 92, and the distance between the bottom of the clamping plate 93 and the top of the cutting table 1 is less than the distance between the bottom of the cutting saw and the top of the cutting table 1. The limiting block 94 is fixed to the upper end of the vertical rod 92, and the spring 95 is fixed between the limiting block 94 and the fixed plate 91. During the descent of the electric cutting saw 312, the fixed plate 91, the vertical rod 92 connected to the fixed plate 91, the clamping plate 93 connected to the vertical rod 92, the limiting block 94 connected to the clamping plate 93, and the spring 95 connected to the limiting block 94 all descend. The clamping plate 93 initially contacts the surface of the rebar and remains stationary. As the electric cutting saw 312 continues to descend, the fixed plate 91 continues to move, and the limiting block 94 is gradually stretched until the cutting saw cuts the rebar. After cutting, the electric cutting saw 312 rises and resets, causing the fixed plate 91, the vertical rod 92 connected to the fixed plate 91, the clamping plate 93 connected to the vertical rod 92, the limiting block 94 connected to the clamping plate 93, and the spring 95 connected to the limiting block 94 to rise and reset for use in the next cutting operation. The positioning component 9 improves the stability during rebar cutting.

[0028] A horizontal plate 10 is fixed on the limiting seat 5, and an indicator needle 11 is fixed at the upper end of the horizontal plate 10. A scale line is set on the side wall of the cutting table 1 near the position of the indicator needle 11. The setting of the horizontal plate 10, the indicator needle 11 and the scale line makes it easy to read the degree of the required cutting length. The length of the steel bar is equal to the distance between the vertical section of the limiting seat 5 and the middle of the cutting groove 2.

[0029] The vertical section of the limiting seat 5 has a limiting groove 12 that communicates with the discharge through hole. The number of limiting grooves 12 is equal to the number of placement grooves 4, and their positions correspond one-to-one. The setting of the limiting grooves 12 improves the stability during steel bar cutting.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
