Description

Technical Field

[0001] The utility model relates to the field of steel bar cutting devices, in particular to a steel bar cutting device for construction. Background Art

[0002] Architecture is a general term for buildings and structures. It is an artificial environment created by people to meet the needs of social life, using the material and technical means they have mastered, and applying certain scientific laws and aesthetic principles. The objects of architecture range from comprehensive environmental design and construction, including regional planning, urban planning, landscape design, and related construction processes before the formation of a community, to the production of indoor furniture and small objects. Its usual objects are units within a certain site. When constructing a building, we will use a steel bar cutting device to cut the steel bars;

[0003] The Chinese patent with the publication number CN211465674U discloses a steel bar cutting device for construction, including a fixed plate, a cutting machine is fixedly connected to the middle position of one side of the fixed plate, a bottom plate is fixedly connected to the bottom position of one side of the fixed plate, a workbench is fixedly connected to the top of the bottom plate, and steel bar placement blocks are fixedly connected to the two sides of the top of the workbench. The steel bar cutting device for construction can prevent the scrap iron from splashing outward along the direction of the blade rotation when the steel bar is cut through the setting of the baffle plate, and the scrap iron is softly contacted when it falls on the baffle plate through the setting of the anti-scalding rubber pad, which can reduce the noise of the scrap iron falling on the baffle plate, and the anti-scalding rubber pad can buffer the impact force of the scrap iron falling on the baffle plate, and the setting of the magnetic plate can generate a large magnetic force to adsorb the scrap iron falling on the baffle plate, so that the scrap iron is gathered on the baffle plate, which is convenient for users to clean.

[0004] When cutting steel bars, the steel bar cutting device of the above patent first fixes the steel bars and then uses a blade to cut the steel bars. However, during the cutting process, the steel bars are fixed and the cutting direction of the blade is also fixed. Therefore, when the blade cuts the steel bars, since the cutting direction of the blade is from top to bottom, the final cut section is also biased downward, which looks unsightly. Utility Model Content

[0005] The utility model aims to provide a steel bar cutting device for construction, wherein a rotating motor is arranged on a fixed block, a three-jaw self-centering chuck is arranged on the output end of the rotating motor, a ground contact base is arranged at the lower end of the fixed block, a connecting block is arranged on the ground contact base, and a stabilizing roller is arranged on the connecting block. When a user inserts a steel bar into the three-jaw self-centering chuck, the rotating motor drives the three-jaw self-centering chuck to rotate. At this time, in order to prevent the steel bar from being unstable in gravity during rotation due to excessive length, the steel bar is placed on two stabilizing rollers to ensure the stability of the steel bar during rotation, and then the cutting blade is started. The rotating direction of the cutting blade is opposite to the rotating direction of the three-jaw self-centering chuck. The cutting blade is pressed down to cut the steel bar. The cutting blade in the opposite direction to the rotating direction of the steel bar can cut toward the center of the steel bar step by step from multiple angles when cutting the steel bar, thereby ensuring the smoothness of the incision and solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction steel bar cutting device, comprising a ground-contacting base, a connecting block is arranged on the ground-contacting base, a rotating bearing is arranged on the connecting block, a stabilizing roller is arranged on the movable end of the rotating bearing, and a slide rail is arranged in the ground-contacting base, a mounting block is arranged on the slide rail, a hydraulic cylinder is arranged on the mounting block, a fixed block is arranged on the movable end of the hydraulic cylinder, a rotating motor is arranged on the fixed block, a three-jaw self-centering chuck is arranged on the output end of the rotating motor, and a support column is arranged on the ground-contacting base.

[0007] Preferably, a damping rotation shaft is provided on one end of the support column away from the ground contacting base, and the fixed end of the damping rotation shaft is bolted to the support column.

[0008] Preferably, a cutting blade is provided on the movable end of the damping rotating shaft.

[0009] Preferably, a handle is provided on the cutting blade housing.

[0010] Preferably, a connecting base is provided at the lower end of the ground contacting base, and the connecting base and the ground contacting base are integrally provided.

[0011] Preferably, a bolt hole is provided on the connecting base, and the bolt hole and the connecting base are integrally arranged.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model is provided with a rotating motor on a fixed block, and a three-claw self-centering chuck is provided on the output end of the rotating motor, and a ground contact base is provided at the lower end of the fixed block, and a connecting block is provided on the ground contact base, and a stabilizing roller is provided on the connecting block. When a user inserts a steel bar into the three-claw self-centering chuck, the rotating motor drives the three-claw self-centering chuck to rotate. At this time, in order to prevent the steel bar from being unstable in gravity center during rotation due to excessive length, the steel bar is placed on two stabilizing rollers to ensure the stability of the steel bar during rotation, and then the cutting blade is started, and the rotating direction of the cutting blade is consistent with the rotating direction of the three-claw self-centering chuck. In the opposite direction, the cutting blade is pressed down to cut the steel bar. The cutting blade in the opposite direction to the rotation direction of the steel bar can cut toward the center of the steel bar gradually from multiple angles when cutting the steel bar, ensuring the smoothness of the incision. This effectively avoids the problem that the existing steel bar cutting device fixes the steel bar first and then uses the blade to cut the steel bar when cutting the steel bar, but the steel bar is fixed during the cutting process and the cutting direction of the blade is also fixed. Then when the blade cuts the steel bar, because the cutting direction of the blade is from top to bottom, the final incision section is also biased downward, which looks unsightly.
