Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a steel bar cutting machine for construction engineering. Background Art

[0002] The steel bar cutting machine converts the rotary motion into the reciprocating linear motion of the blade by a crankshaft connecting rod mechanism. When the steel bar is placed at the specified position, with the reciprocating motion of the blade, the blade and the fixed blade (or anvil) form a shearing effect. When the blade applies sufficient pressure to the steel bar, the steel bar will be cut off; during the construction of the cast-in-place slab, during the steel bar binding process of the slab, the stirrup bars are used to support the upper layer of steel bars, preventing the upper steel bars from sinking and shifting during the concrete pouring process, ensuring the correct position and the cover thickness of the steel bars. The production length requirements of the stirrup bars are relatively strict. If the length of the stirrup bars is inaccurate, it may lead to the inability to effectively support the upper steel bars, affecting the positioning of the steel bars and the cover thickness, and may further have an adverse impact on the safety and durability of the structure. Generally, precise calculation and production are required according to the specific slab thickness, steel bar specifications, design requirements, etc. to meet the construction quality requirements;

[0003] When the existing steel bar cutting machine is used to process and manufacture stirrup bars, a sufficiently long steel bar needs to be continuously cut into multiple stirrup bars. The length of the stirrup bars needs to be in accordance with the actual construction requirements. When cutting the steel bar, it is necessary to ensure that the length of the cut stirrup bars meets the design standards. When cutting the steel bar, it is necessary to adjust the position of the steel bar on the cutting tool head, and the position of the steel bar needs to be positioned. At the same time, a large number of stirrup bars of the same size need to be manufactured, and the required sizes of the stirrup bars are different in the lengths of each pouring slab surface. The staff needs to position the steel bar according to the stirrup bars of each length. Therefore, it is not conducive for the staff to carry out batch and rapid processing work on stirrup bars of different lengths. Content of the Utility Model

[0017] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions: including a cutting machine body 1, two fixed blocks 11 are installed on one side of the cutting machine body 1, an arc-shaped plate 111 is fixedly connected between the two fixed blocks 11, a support rod 12 is fixedly connected to the fixed block 11, one end of the support rod 12 is fixedly connected to a fixed plate 3, a lower motor 31 is fixedly connected to one side of the fixed plate 3, the driving end of the lower motor 31 is fixedly connected to a lower threaded rod 32, an adjusting plate 33 is threadedly connected to the lower threaded rod 32, a support plate 34 corresponding to the arc-shaped plate 111 is slidably connected to the adjusting plate 33, a connecting plate 4 and a limit plate 35 are fixedly connected to the inner wall of the support plate 34, a vertical plate 41 is fixedly connected to the connecting plate 4, an upper motor 44 is fixedly connected to the adjusting plate 33, and the driving end of the upper motor 44 is fixedly connected to an upper threaded rod 42, and the upper threaded rod 42 is threadedly connected to the vertical plate 41.

[0018] In this implementation: The cutting machine body 1 is used to cut steel bars. By placing the steel bar at the telescopic position at one end of the cutting tool head, the cutting tool head can cut the steel bar. The fixed block 11 installed on the cutting machine body 1 can fix the chute 13 when the steel bar is cut, so that the steel bar can be placed below the steel bar. The arc-shaped plate 111 fixedly connected between the fixed blocks 11 can support and limit the steel bar, so that when the steel bar is on the arc-shaped plate 111, it can be supported by the chute 13 fixedly connected to the fixed block 11. The adjusting plate 33 slidably connected to the chute 13 can slide on the chute 13 to adjust the distance between it and the cutting machine body 1. At the same time, the fixed plate 3 fixedly connected to one end of the chute 13 can install and fix the lower motor 31, and the driving end of the lower motor 31 can drive the lower threaded rod 32, so that the lower threaded rod 32 can rotate to adjust the position of the adjusting plate 33 on the chute 13, thereby adjusting the distance between the support plate 34 slidably connected to the adjusting plate 33 and the cutting machine body 1. The limiting plate 35 fixedly connected to the inner wall of the support plate 34 can limit one end of the steel bar, so that when the steel bar is cut, at this time, one end of the steel bar can support on the limiting plate 35 to limit its position, so that the distance between the cutting head of the steel bar on the cutting machine body 1 and the limiting plate 35 can be adjusted when adjusting the position of the adjusting plate 33, so that the device can adjust the position of the limiting plate 35 according to actual needs, and thus fix the position of the limiting plate 35 according to the required length of the stirrup bar. After one end of the steel bar supports on the limiting plate 35 and is cut by the cutting head on the fixed block 11, the section of the steel bar between the limiting plate 35 and the cutting head is cut into a stirrup bar. At this time, the upper motor 44 fixedly connected to the top of the adjusting plate 33 can drive the upper threaded rod 42. When the upper threaded rod 42 rotates, the vertical plate 41 threadedly connected to the outer wall of the upper threaded rod 42 can adjust its position on one side of the adjusting plate 33. After the connecting plate 4 fixedly connected to the bottom end of the vertical plate 41 is fixed to the inner wall of the support plate 34, the position of the limiting plate 35 can be adjusted by the rotation of the upper threaded rod 42. When the cut steel bar slides to the left side of the adjusting plate 33, a section of the cut steel bar can be separated and displaced from the support plate 34, so that it can fall downward, thus facilitating the separation of the cut steel bar. After separation, the upper motor 44 drives the upper threaded rod 42 to rotate to reset the position of the limiting plate 35, so that the remaining uncut part of the steel bar can support on the limiting plate 35 again, and the device can adjust the position of the adjusting plate 33, so that the device can adjust to the position required for the length of the stirrup bar according to the position of the limiting plate 35, thus facilitating the device to process and manufacture the stirrup bar according to actual needs.

[0019] Both sides of the rod support 12 are provided with sliding grooves 13. A sliding frame 2 is slidably connected to the rod support 12. A slider 23 matching the sliding groove 13 is fixedly connected to the sliding frame 2. A push rod 21 is slidably connected to the sliding frame 2. A spring 22 is sleeved on the outer wall of the push rod 21. The sliding grooves 13 provided on both sides of the rod support 12 are used to limit the slider 23 fixedly connected to the inner wall of the sliding frame 2. When the sliding frame 2 slides on the rod support 12, the sliding frame 2 can be ensured to be supported under the limitation of the sliding groove 13 and the slider 23. The push rod 21 slides on the sliding frame 2. A downward traction force is provided to the top of the push rod 21 through the spring 22 sleeved on the outer wall of the push rod 21, so that the push rod 21 can slide downward, and the push rod 21 can press the cut steel bars downward, so that the cut steel bars can be discharged.

[0020] A sliding hole 341 matching the support plate 34 is provided at the connection of the adjusting plate 33 and the support plate 34. A lower limiting rod 321 is fixedly connected between the fixed block 11 and the fixing plate 3. The lower limiting rod 321 is slidably connected to the adjusting plate 33. One end of the lower threaded rod 32 is rotatably connected to the fixed block 11. The sliding hole 341 is used to install the support plate 34, so that the support plate 34 can slide on the adjusting plate 33. At the same time, the limiting plate 35 and the connecting plate 4 are limited, so that the support plate 34 will not be separated from the adjusting plate 33. The lower limiting rod 321 is slidably connected to the adjusting plate 33. When the adjusting plate 33 is driven by the lower threaded rod 32 to adjust its position, the lower limiting rod 321 can limit it, ensuring that the adjusting plate 33 slides horizontally on the rod support 12.

[0021] An upper limiting rod 43 is fixedly connected to one side of the adjusting plate 33. The vertical plate 41 is slidably connected to the upper limiting rod 43. The upper limiting rod 43 fixedly connected to one side of the adjusting plate 33 is used to limit the bottom of the vertical plate 41. When the vertical plate 41 adjusts its position on the upper threaded rod 42, under the limitation of the upper limiting rod 43, it can be ensured that it slides horizontally on one side of the adjusting plate 33, pushes the connecting plate 4, and makes the support plate 34 slide.

[0022] The limiting plate 35 and the connecting plate 4 are respectively located on both sides of the adjusting plate 33. The upper limiting rod 43 and the upper threaded rod 42 match the support plate 34. The limiting plate 35 and the connecting plate 4 are respectively located on both sides of the adjusting plate 33, so that while the support plate 34 will not be separated from the sliding hole 341, the amount of the left and right sliding displacement of the support plate 34 is limited. After the position where the limiting plate 35 supports the steel bars is reset, the connecting plate 4 supports on one side of the adjusting plate 33, and quickly and accurately resets it, ensuring the cutting length of the steel bars.

[0023] Working principle and usage process of the utility model: When in use, first drive the lower threaded rod 32 by controlling the lower motor 31, so that the lower threaded rod 32 can rotate to adjust the position of the adjusting plate 33 on the sliding groove 13, thereby adjusting the distance between the support plate 34 slidably connected to the adjusting plate 33 and the cutting machine body 1. When adjusting the position of the adjusting plate 33, support on one side of the adjusting plate 33 through the connecting plate 4 fixedly connected to the inner wall of the support plate 34. Support one end of the steel bar on the limiting plate 35 to limit the position of the steel bar, so as to fix the cutting length of the steel bar according to the position of the limiting plate 35. Fix the position of the limiting plate 35 according to the required length of the stirrup. After one end of the steel bar supports on the limiting plate 35, it is cut by the cutting head on the fixing block 11. After cutting, drive the upper threaded rod 42 by the upper motor 44, so that the vertical plate 41 can move the connecting plate 4 for displacement. Since the connecting plate 4 and the limiting plate 35 are connected through the limiting plate 35, the limiting plate 35 moves outwards, separating the support received by one end of the cut steel bar. After separation, drive the upper threaded rod 42 to rotate by the upper motor 44 to reset the position of the limiting plate 35, so that the remaining uncut part of the steel bar can support on the limiting plate 35 again, enabling the device to adjust the position of the adjusting plate 33, enabling the device to adjust to the position of the required stirrup length according to the position of the limiting plate 35, thereby facilitating the device to process and manufacture stirrups according to actual requirements.
