Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting, in particular to a numerical control shearing device for automatically cutting steel bars. Background Art

[0002] As an indispensable skeleton material in modern building structures, the strength, toughness and durability of steel bars are directly related to the overall stability and service life of the building. As the first step in steel bar processing, the precision and efficiency of cutting steel bars directly affect the quality and progress of subsequent construction. Although the steel bar shears in the prior art can cut steel bars with smaller diameters, they can only cut one steel bar at a time, and their working efficiency is low.

[0003] In response to the above problems, a patent document with authorization announcement number CN219616616U discloses a steel bar cutting device, which is provided with a mounting seat and a steel bar fixing piece on a base, and a plurality of fixing grooves for fixing steel bars are arranged at intervals on the steel bar fixing piece, one end of a first connecting rod is hinged to the mounting seat, and the other end is hinged to one end of a second connecting rod, and the other end of the second connecting rod is hinged to a force applying rod, and a cutting piece is arranged on the first connecting rod and rotates synchronously with the first connecting rod. When in use, the steel bars to be cut are placed in each fixing groove respectively, and the force applying rod is driven to move by a force mechanism, thereby driving the cutting piece to rotate around its end, and utilizing the extrusion effect between the cutting piece and the steel bar fixing piece to cut the steel bars in each fixing groove, so that multiple steel bars can be cut at the same time, thereby improving work efficiency.

[0004] It can be seen that although the above-mentioned steel bar cutting device can cut multiple steel bars at a time, it needs to drive the second connecting rod and the first connecting rod to rotate in turn after applying force to the force rod, thereby driving the cutting piece to rotate, but its driving process is relatively complicated, requiring precise coordination and synchronization between the two connecting rods and the force rod. There will be accumulated errors between the force rod and the two connecting rods during the transmission process, resulting in a deviation between the actual position of the cutting blade and the preset position, thereby affecting the cutting accuracy and reducing the quality of the cutting surface.

[0005] The utility model provides a numerical control shearing device for automatically cutting steel bars, so as to solve the technical problem in the prior art that the driving process of the cutting piece is complicated, resulting in error accumulation during the cutting process, thus affecting the cutting accuracy and cutting quality.

[0006] In order to solve the above problems, the numerical control shearing device for automatically cutting steel bars provided by the utility model adopts the following technical solutions:

When in use, the steel bar passes horizontally through the positioning hole on the guide piece, and the driving mechanism drives the transmission rod to move downward, thereby driving the cutting tool to move downward, so that the steel bar can be cut off. Only one transmission rod is used to drive the cutting tool to move, and the structural form is simple, which avoids the occurrence of error accumulation in the transmission process due to the use of multiple transmission rods, and improves the cutting accuracy and cutting quality.
