Problems solved by technology

However, this steel bar bending machine cannot control the bending angle of the steel bar very well, and in addition, it can only bend the steel bar to a certain fixed value of the bending radius of curvature, so the scope of application is narrow

Embodiment 1

[0023] A semi-automatic steel bar bending machine, such as figure 1 As shown, a machine tool is included, and the upper part of the machine tool is provided with a working plate 2 which is connected to the machine tool. A rotating disk 3 is provided at the center of the working disk 2. The rotating disk 3 is connected to a power mechanism inside the machine tool, and the power mechanism can drive the rotating disk 3 to rotate around its own axis. A number of positioning shaft holes 5 and clamping shaft holes 7 are uniformly distributed on the rotating disk 3 along the circumferential direction of the rotating disk 3, and the distance between the positioning shaft holes 5 and the clamping shaft holes 7 is adapted to the diameter of the steel bar to be bent , A number of positioning shaft holes 5 are distributed in a circle on the rotating disk 3, and the center of the circular positioning shaft holes 5 coincides with the center of the rotating disk 3; the clamping shaft hole 7 ca...

Embodiment 2

[0026] On the basis of the first embodiment, the working disk 2 and the rotating disk 3 are also provided with scale lines 10, and the number of scale lines 10 on the rotating disk is more than the number of scale lines 10 on the working disk 2, and the working disk 2 And the rotating disk 3 are marked with "0" scale line 1.

[0027] In this embodiment, the number of scale lines 10 on the working disk 2 is 32, the angle between two adjacent scale lines 10 on the working disk 2 is 11.25°; the number of lines 10 on the rotating disk is 36, The angle between two adjacent graduation lines 10 on the rotating disk is 10°. When the "0" scale line 1 of the working disc 2 and the rotating disc 3 coincide, the angle between the first scale line 10 is 1.25°. Such as figure 1 As shown, at this time, the “0” scale line 1 of the working plate 2 and the rotating plate 3 overlaps, and the steel bar is not bent; but as figure 2 As shown, at this time, the "0" scale line 1 of the working disk 2 ...

Embodiment 3

[0029] On the basis of the first or second embodiment, the positioning shaft 4 is provided with a positioning collar 41; the clamping shaft 6 is provided with a clamping collar 61. The positioning clamp ring 41 is set on the positioning shaft 4, which can effectively prevent the steel bar from sliding during the bending process, and ensure the bending accuracy and bending quality of the semi-automatic steel bending machine; the clamp shaft 6 is provided with a clamp clamp ring 61, which can To further prevent the steel bar from sliding during the bending process.

Abstract

The invention discloses a semiautomatic steel bar bender, which relates to the technical field of steel bar-bending equipment. The invention aims to provide the semiautomatic steel bar bender which can deal with steel bars with different bending radii. The technical scheme of the invention is as follows: the semiautomatic steel bar bender comprises a machine bed, a working plate which is connected with the machine bed is arranged on the top of the machine bed, a rotary disk is arranged at the center of the working plate, the rotary disk is connected with a power mechanism in the machine bed and can rotate around the axis of the rotary disk, a plurality of positioning shaft holes and clamping shaft holes are evenly distributed along the circumferential direction of the rotary disk on the rotary disk, the positioning shaft holes form a plurality of concentric circles on the rotary disk, positioning shafts and clamping shafts are respectively correspondingly placed in the positioning shaft holes and the clamping shaft holes, backing pin blocks and rollers are arranged on both sides of the working plate, and backing pins are arranged on the backing pin blocks. The invention is applicable to steel bar bender.

Description

Technical field [0001] The invention relates to the technical field of steel bar bending and forming equipment, in particular to a steel bar bending machine. Background technique [0002] With the gradual development of my country’s economic construction, civil engineering projects are being carried out all over the country, and various residential, office buildings, road projects and other under-construction projects are being built. However, no matter whether it is on the construction sites of many under-construction projects or steel bar production workshops, it is often necessary to Large quantities of steel bars are bent. For the bending of steel bars, the more traditional method is mainly operated manually, but manual bending of steel bars not only requires a lot of manpower, but also takes up a lot of construction space. Therefore, in order to solve this problem, a commonly used steel bar processing machine, a steel bar bending machine, has appeared in the prior art. T...
