Problems solved by technology

[0005] In order to overcome the disadvantage that although the current steel bar bending device can cut the steel bar, it cannot fix the cut steel bar, and it is easy to make the steel bar roll freely after the steel bar is cut, causing injury to the workers. The technical problem to be solved is: provide a A bending steel bar cutting device for building construction that can fix the cut steel bars and prevent them from rolling freely

Embodiment 1

[0021] A bending steel bar shearing device for building construction, such as Figure 1-3 As shown, it includes a mounting frame 1, a handle 2, a guide assembly and a shearing assembly. The upper part of the mounting frame 1 is fixed with the handle 2 through bolts, the lower part of the mounting frame 1 is provided with a guiding assembly, and the lower part of the mounting frame 1 is provided with a shearing assembly.

[0022] When using the device to cut the bent steel bar, first put the device on the ground, then place the bent steel bar on the inside of the guide assembly, the direction of the part to be cut is upward, and then the worker holds the handle 2 Press down to drive the mounting frame 1 to move downward, thereby driving the shearing assembly to move downward. The guide assembly can ensure that the mounting frame 1 and the shearing assembly move vertically downward, and the bending assembly will bend during the vertical downward movement. The steel bar is cut, a...

Embodiment 2

[0028] On the basis of Example 1, such as Figure 4 and 5 As shown, it also includes a second slide rail 14, a third slide block 15, a third spring 16, a U-shaped bar 17 and a splint 18, and the middle part of the installation frame 1 is symmetrically connected with the second slide rail 14 by bolts front and back. In the two slide rails 14, the third slide block 15 is arranged symmetrically on the left and right, and the third spring 16 is connected between the third slide block 15 and the second slide rail 14, and the third slide block 15 is fixed by bolts. A U-shaped bar 17 is connected, and the U-shaped bar 17 is slidably matched with the second slide rail 14, and splints 18 are fixedly connected between the U-shaped bars 17 on the left and right sides by bolts.

[0029] Before placing the bent steel bar, the U-shaped bar 17 can be pulled to the left and right sides, so that the splint 18 is far away from the third slider 15. At this time, the third spring 16 is compresse...

Abstract

The invention relates to a shearing device, in particular to a bent steel bar shearing device for building construction. The bent steel bar shearing device for building construction can fix sheared steel bars and prevent the sheared steel bars from randomly rolling. The bent steel bar shearing device for building construction comprises an installation frame, a handle, a guide assembly and a shearing assembly, the handle is installed on the installation frame, the guide assembly is installed on the installation frame, and the shearing assembly is installed on the installation frame. According to the device, bent steel bars can be sheared by pressing the handle after the bent steel bars are placed, the handle is loosened after the bent steel bars are sheared, and the device can reset automatically; and the bent steel bars can be clamped and fixed before being sheared, so that the condition that the bent steel bars fall and roll freely after being sheared and easily injure workers is effectively prevented.

Description

technical field [0001] The invention relates to a shearing device, in particular to a bending steel bar shearing device for building construction. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars are mostly used in construction and are responsible for the support of heavy objects. However, when using steel bars that do not need to be bent during construction, it is necessary to cut the bent steel bars. [0003] The patent authorization notification number is CN207325836U, which discloses a steel bar breaking machine for construction, including a workbench, the top of the workbench is fixedly connected with a U-shaped plate, and the top and bottom of the inner wall of the U-shaped plate are movably connected with Rotating shaft, the top of the rotating shaft pas...
