Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel processing, in particular to a high-stability threaded steel shearing device. Background Art

[0002] The rebar shearing device is a device used to cut rebar. Rebar is usually used in buildings, bridges and other engineering structures. Therefore, it needs to be cut to a fixed length at the construction site or steel processing plant for subsequent processing and use.

[0003] After searching, a Chinese patent application with the publication number of CN218134054U has been found to be related to a high-stability threaded steel shearing device, comprising a water tank (2) arranged above the threaded steel (1), a group of spray holes (2a) being arranged at the bottom of the water tank (2), the spray holes (2a) being arranged facing the head of the threaded steel (1), a cooling water external interface (2b) being arranged at the side of the water tank (2), and the cooling water external interface (2b) being connected to an external cooling water pipe (3). The utility model can be used normally by connecting an external cooling water pipe. After the cooling water is connected, the water source enters the spray water tank, and the cooling water in the water tank is sprayed uniformly at the position to be sheared at the threaded steel head through the spray holes at the bottom at the same rate, so that the temperature of this position is rapidly cooled, so that the shearing temperature of the position to be sheared at the position to be sheared after reaching the length setting machine is reduced to below 400°C, thereby effectively avoiding the phenomenon of the threaded steel head shearing head drooping.

[0004] Although the above patent can reduce the shearing temperature to below 400°C by externally connecting a cooling water pipe, thereby effectively avoiding the problem of the head of the threaded steel bar being bent when sheared, the above technology still has the disadvantage that when shearing threaded steel bars, it is necessary to replace clamps of different sizes to clamp the threaded steel bars according to the size of the threaded steel bars when cutting threaded steel bars of different sizes, which takes a lot of time. In addition, the shearing process is prone to large deformation and irregular shapes of the cuts, which makes the quality of the cuts difficult to control, affecting subsequent processing and use, and is not conducive to people's use. For this reason, we propose a high-stability threaded steel shearing device to solve the above problems. Utility Model Content

[0034] Specifically, when it is necessary to clamp the threaded steel bar, the first motor 15 is started to drive the rotating rod 14, and then drive the connecting rod 13 to move on the outside of the limit rod 12, so that the slide plate 11 moves under the limit of the limit rod 12, so that the connecting block 24 moves in the slide groove 6, and then the clamp 5 moves, so that the clamp 5 moves toward the threaded steel bar, and the threaded steel bar is clamped by the anti-slip pad on the clamp 5. The threaded steel bar is a steel bar with threads, and the usual specifications are HRB335 and HRB400, so that the spacing of the clamps can be adjusted, and the clamps can clamp threaded steel bars of different sizes, so that the threaded steel bars are fixed on the workbench. Compared with the prior art, when cutting threaded steel bars of different sizes, it is necessary to replace clamps of different sizes, which saves more time.

[0036] Specifically, the connecting rod 13 moves under the action of the rotating rod 14 driven by the first motor 15, thereby driving the slide plate to move. The slide plate 11 drives the connecting block 24 to move in the slide groove under the action of the limiting rod 12, thereby driving the clamping plate 5 to clamp the threaded steel bar on the workbench 7 through the anti-slip pad.

[0037] Reference Figure 1 , Figure 2 and Figure 5 A mounting groove 9 is provided on the inner side of the bracket 1, and a second motor 21 is fixedly connected inside the mounting groove 9, and a threaded rod 10 is fixedly connected to the output end of the second motor 21, and a slider 22 is threadedly connected to the outer side of the threaded rod 10, and a cylinder 2 is fixedly connected to the bottom side of the slider 22, and a tool holder 26 is fixedly connected to the bottom of the cylinder 2, and a third motor 25 is fixedly connected to the outer side of the tool holder 26, and a blade 3 is fixedly connected to the output end of the third motor 25, and the outer side of the slider 22 is in contact with the inner wall of the mounting groove 9, and the end of the threaded rod 10 away from the second motor 21 is movably connected to the inner wall of the mounting groove 9 through a bearing.

[0038] Specifically, when it is necessary to cut the rebar, the third motor 25 is started to drive the blade 3 to rotate. At the same time, the second motor 21 is started to drive the threaded rod to rotate, and then the slider 22 is driven to move left and right, so that the cylinder 2, the tool holder 26, the blade 3 and the third motor 25 move, and then accurately reach the top of the rebar. At this time, the cylinder 2 is started, so that the output end of the cylinder 2 drives the tool holder 26 to move downward, and then the blade cuts the rebar, thereby clamping the rebar, and then the rebar is fixed on the workbench, so that the position of the blade cutting the rebar can be adjusted.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The dust removal component includes a suction fan 20 and a filter box 16, both of which are fixedly connected to the outside of the bracket 1, the output end of the suction fan 20 is fixedly connected to an air outlet pipe 19, the inner side of the filter box 16 is fixedly connected to a plurality of filter screens 17, one side of the filter box 16 is fixedly connected to an air inlet pipe 18, the other end of the air inlet pipe 18 is fixedly connected to a dust hood 4, and one end of the air outlet pipe 19 is connected to the inside of the filter box 16.

[0040] Specifically, by starting the suction fan 20, the dust is driven into the dust hood, so that the dust enters the filter box 16 through the air inlet pipe 18, and then the dust is filtered through the filter net 17, so that clean air is blown to the workbench, and the dust on the workbench is removed.

[0041] Reference Figure 1 , Figure 2 and Figure 5 Universal wheels 8 are installed at the four corners of the bottom end of the workbench 7.

[0042] Specifically, a high-stability threaded steel shearing device is driven by the universal wheel 8 to change the working scene.

[0043] Working principle: when it is necessary to cut the rebar, start the first motor 15 so that the output end of the first motor 15 drives the rotating rod 14 to rotate, thereby driving the connecting rod 13 to move, and then driving the slide plate 11 to move under the limit of the limit rod 12, thereby driving the connecting block 24 to move in the slide groove 6, so that the two clamps 5 are fitted together, so that the rubber pads on the clamps 5 clamp the rebar, and then the clamp can clamp rebars of different sizes, so that the rebar is fixed on the workbench. Compared with the prior art, it is necessary to replace clamps of different sizes when cutting rebars of different sizes, which saves more time.

[0044] When it is necessary to cut the rebar, the third motor 25 is started to drive the blade 3 to rotate, and the cylinder 2 is started at this time, so that the blade 3 descends to cut the rebar. When it is necessary to adjust the cutting position of the blade, the second motor 21 is started to drive the threaded rod 10 to rotate, and then the slider 22 is driven to move, thereby driving the cylinder 2 and the blade 3 thereon to move, thereby achieving the requirement of adjusting the cutting position.

[0045] In addition, a lot of dust will be generated when cutting threaded steel bars. At this time, by starting the suction fan 20, the filter box 16 reaches a negative pressure state, so that the dust hood 4 sucks in the dust generated when cutting the threaded steel bars, and then enters the filter box 16 through the air inlet pipe 18, so that the dust is filtered through multiple filter screens 17 and then discharged, thereby ensuring that the staff can have a clean working environment when working, which is convenient for people to use.
