Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting equipment, in particular to a fixed-length cutting device for building steel bars. Background Art

[0002] In the construction industry, steel bars, as an important building material, are widely used in various building structures to enhance the stability and bearing capacity of buildings. Especially in large, heavy, light thin-walled and high-rise building structures, the role of steel bars is indispensable. However, in the construction process, the cutting and size adjustment of steel bars is a common demand.

[0003] The traditional method of cutting steel bars mainly relies on manual operation using steel bar pliers or vises. This cutting method is not only inefficient, but also has low cutting accuracy and requires high physical strength and skills of operators. Long-term operation not only easily makes operators feel tired, but also may lead to poor cutting effect due to improper operation, affecting the subsequent construction quality and safety.

[0004] In addition, there are some steel bar cutting devices on the market, but most of these devices have the following problems:

[0005] 1. Poor fixing effect: During the cutting process, the steel bars are prone to slight movement, resulting in inaccurate cutting position.

[0006] 2. Low cutting efficiency: Traditional cutting devices often require manual operation, which is not only slow but also has unstable cutting effect.

[0007] 3. Low cutting accuracy: Due to the design and manufacturing accuracy limitations of the device itself, as well as errors during operation, the length and shape of the steel bars after cutting do not meet the requirements.

[0008] 4. Loud noise: Some cutting devices will generate loud noise during the cutting process, affecting the working environment and the health of operators.

[0009] In order to solve the above problems and improve the efficiency, accuracy and safety of steel bar cutting, the utility model proposes a fixed-length cutting device for building steel bars. The device realizes automatic fixed-length cutting of steel bars through precise design and advanced control technology, and has the advantages of high efficiency, accuracy, safety and environmental protection, and can meet the needs of modern building construction.

The upper end of the clamping seat 302 is vertically fixedly connected to the end of the piston rod of the first electric cylinder 301, and the left and right ends of the clamping seat 302 are rotatably installed with pressing wheels 303 respectively.

The end of the cutting frame 4 away from the connecting shaft seat 401 is rotatably connected to a lever connecting block 404 through a lever connecting shaft 403. The lever connecting block 404 is a shuttle-shaped structure. The top end of the lever connecting block 404 is rotatably connected to the end of the piston rod of the second electric cylinder 402 through a pin shaft. The other end of the lever connecting block 404 is provided with a U-shaped penetrating connecting shaft groove 40401. The directional sleeve block 405 has a directional slot 40501 vertically formed at a position below the lever connecting block 404 in the directional sleeve block 405. A connecting knife plate 406 is vertically slidably installed in the directional slot 40501. The connecting knife plate 406 is vertically slidably installed in the directional slot 40501 through a directional guard plate 40502. The directional guard plate 40502 and the directional slot 40501 are fixedly connected by bolts. A cutting knife 40601 is fixedly connected to the lower end of the connecting knife plate 406 by bolts. The left end side wall of the cutting knife 40601 is slidably tangent to the right end side wall of the fixed-length pipe box 2.

[0046] Embodiment 2, on the basis of embodiment 1, after the construction steel bar to be cut is in the fixed groove 203, the first electric cylinder 301 works to push the clamping seat 302 downward, the lower end of the pressure wheel 303 is tangent to the upper end of the construction steel bar to be cut, the reciprocating rotating motor 305 works to drive the pressure wheel 303 to rotate, and the construction steel bar to be cut moves to the side where the pressure sensor 204 is located. After the pressure sensor 204 is squeezed and sends a signal, the controller 5 controls the second electric cylinder 402 to work, and the cutting knife 40601 moves downward to cut the construction steel bar.

[0047] The working principle of this embodiment:

[0048] First, one end of the building steel bar to be cut is placed on the discharge guide slope block 201 of the fixed-length pipe box 2. Due to the inclined structure of the discharge guide slope block 201, the building steel bar will naturally slide into the fixed placement groove 203 in the fixed-length pipe box 2. During the sliding process, due to the precise design of the fixed placement groove 203, the building steel bar can be accurately positioned at a preset length position;

[0049] Next, the clamping control frame 3 starts to work. After receiving the command from the controller 5, the first electric cylinder 301 pushes the clamping seat 302 to move downward, and the clamping seat 302 drives the two pressing wheels 303 thereon to move downward until the lower end of the pressing wheel 303 is tangent to the upper end of the building steel bar to be cut. At this time, the pressing wheel 303 plays a role in fixing the position of the building steel bar to prevent it from moving during the subsequent cutting process.

[0050] Then, the reciprocating rotary motor 305 starts to work, which drives one of the pressing wheels 303 to rotate. Since the two pressing wheels 303 are connected by a belt 304, the two pressing wheels 303 rotate at the same speed and in opposite directions. This rotational motion will generate a thrust toward the side where the pressure sensor 204 is located, pushing the construction steel bar to be cut to move along the fixed groove 203 toward the pressure sensor 204;

[0051] When the end of the building steel bar contacts the pressure sensor 204, the pressure sensor 204 will be squeezed and send a signal, and the signal will be transmitted to the controller 5. After receiving the signal, the controller 5 will immediately control the second electric cylinder 402 to start working;

[0052] The piston rod of the second electric cylinder 402 pushes the lever connecting block 404 to move downward. Since the lever connecting block 404 is connected to the connecting blade plate 406, the connecting blade plate 406 will also move downward. The directional sleeve block 405 provides a stable guide for the connecting blade plate 406 to ensure that it remains vertical during the movement. When the connecting blade plate 406 moves downward to a certain position, the cutting knife 40601 at its lower end will contact the right end side wall of the building steel bar and exert sufficient shear force to cut the building steel bar.

[0053] After the cutting is completed, the controller 5 controls the first electric cylinder 301 and the second electric cylinder 402 to return to the initial position so as to perform the next cutting operation. At the same time, the operator can take out the cut building steel bars from the other end of the fixed-length pipe box 2 and continue to put new building steel bars to be cut into the fixed-length pipe box 2.
