Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending devices, in particular to a building steel bar bending device. Background Art

[0002] The background technology of the building steel bar bending device involves the treatment of steel bar structures in construction. During the construction process, when reinforcing and pouring structures such as floor slabs, beams, and columns, it is usually necessary to use steel bars to fill the skeleton to increase the strength of the concrete structure. In order to ensure the stability of the steel bar structure, the steel bars need to be bent according to specific construction requirements so that they can be used in conjunction with the construction.

[0003] At present, in the prior art, some small-sized hydraulic steel bar bending devices that are easy to carry often lack protective devices on the surface of the bending devices, so that when the steel bar bending devices bend some steel bars with hidden damage inside, the hidden damage on the steel bars will tear, causing the steel bars to collapse, which can easily cause injuries to operators. In view of this, we propose a construction steel bar bending device. Utility Model Content

[0004] The main purpose of the utility model is to provide a construction steel bar bending device, which can solve the problems raised in the above technical background.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a construction steel bar bending device, including a device body, the inner wall of the device body is provided with a protective device, and the protective device includes:

[0006] A reed, one end of which is fixedly connected to the inner wall of the device body, the other end of which is fixedly connected to the upper surface of the protective shell, and the inner wall of the protective shell is slidably connected to the surface of the device body.

[0007] Preferably, a V-shaped groove is formed on the inner wall of the protective shell, and a pressing block is slidably connected to the inner wall of the protective shell.

[0008] Preferably, the surface of the pressing block is in contact with the surface of the L-plate, and the surface of the L-plate is rotatably connected to the inner wall of the protective shell.

[0009] Preferably, one protective shell and one reed are a group, two groups are provided in total, and the protective shell is hinged to another protective shell.

[0010] Preferably, the device body comprises a base plate, a stopper is fixedly connected to the upper surface of the base plate, a hydraulic sleeve is fixedly connected to the upper surface of the base plate, and a hydraulic rod is slidably connected to the inner wall of the hydraulic sleeve.

[0011] Preferably, an extrusion head is fixedly connected to the end surface of the hydraulic rod, a baffle is fixedly connected to the surface of the extrusion head, and a pressing groove is fixedly connected to the upper surface of the bottom plate, and the pressing groove cooperates with the extrusion head.

[0012] Beneficial Effects

[0013] The utility model provides a construction steel bar bending device, which has the following beneficial effects:

[0014] (1) The construction steel bar bending device has a protective shell. When the steel bar needs to be bent, the steel bar is placed on the upper surface of the block, and the external hydraulic device is started, so that the power of the hydraulic device is transmitted to the hydraulic rod through the hydraulic sleeve. The hydraulic rod moves downward, and the hydraulic rod pushes the protective device and the extrusion head to move downward, so that the extrusion head bends the surface of the steel bar. As the bending angle of the steel bar surface increases, the protective shell rotates, so that the surface of the protective shell is more closely attached to the surface of the steel bar, so that the V-shaped groove inside the protective shell can tightly clamp the steel bar to prevent the steel bar from breaking during excessive bending, thereby protecting the user.

[0015] (2) The construction steel bar bending device has a pressure block. As the steel bar is bent, the protective shell and the steel bar surface are more closely fitted, so that the steel bar presses the pressure block, which causes the pressure block to move backward, thereby squeezing the L-plate, causing the L-plate to rotate, so that the L-plate applies a downward force to the steel bar surface, so that the steel bar is firmly fixed in the middle by the L-plate and the block, further enhancing the protective capability of the protective device.
