Abstract
The invention discloses a steel bar bender allowing the bending radius of a steel bar to be selected. The steel bar bender comprises a bender body, a motor, a motor output shaft and a central pin shaft located in a working face of the blender body. The motor output shaft penetrates the central pin shaft and is connected with a rotating disc. The blender body is provided with a plurality of semicircular rings which are concentric with the central pin shaft, and a curve track is formed between the adjacent semicircular rings. A clamping device is arranged in the curve track and comprises a shell. The shell is internally provided with a pressing block, and a rotating handle is arranged on the pressing block and connected with the shell in a threaded fit manner. A telescopic device is rotationally connected between the clamping device and the rotating disc. The telescopic device comprises a threaded rod and a roller, and the threaded rod and the roller are connected in a threaded fit manner. The roller and the rotating disc are rotationally connected, and the threaded rod is connected with the clamping device. The cost can be reduced and the efficiency can be improved.
Description
Technical field
The present invention relates to the angle-bender in building machinery field, in particular to a kind of angle-bender selecting bar bending radius.
Background technology
Along with the progressively development of China's economic construction, all parts of the country, all busy at putting up installations, built the projects in construction such as various house, office building, road engineering, but no matter are in numerous project in construction construction sites, or reinforcing bar workshop, all usually needs to carry out bending process to reinforcing bar in enormous quantities.
Traditional angle-bender is at the U-shaped reinforcing bar of bending different-diameter, and need multiple stage angle-bender could bend out different-diameter U-shaped reinforcing bar, thus meet the needs of site operation, but the cost that multiple stage angle-bender causes is higher, production efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of angle-bender selecting bar bending radius, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is: a kind of angle-bender selecting bar bending radius, comprises body, motor, motor output shaft, is positioned at the central pin shaft of body working face; It is characterized in that: described motor output shaft is connected with rotating disc through central pin shaft; Described body is provided with multiple semicircular ring, and multiple semicircular ring is all concentric with central pin shaft, forms warp rail between adjacent semicircular ring; Be provided with clamping device in described warp rail, described clamping device comprises housing, is provided with compact heap in housing, and compact heap is provided with rotary handle, and rotary handle is connected with housing threaded engagement; Be rotatably connected between described clamping device and rotating disc retractor device; Described retractor device comprises threaded rod and cylinder, and threaded rod is connected by threaded engagement with cylinder, and cylinder and rotating disc are rotatably connected, and threaded rod is connected with clamping device.
The invention has the beneficial effects as follows, because multiple semicircular ring forms multiple annular curved track, need to select different warp rails according to on-the-spot bar bending radius.Threaded rod extended by rotating rotating cylinder or shortens, allowing clamping device enter on above-mentioned selected warp rail, thus realize the bending of different U-shaped reinforcing bar radius.
Accompanying drawing explanation
Fig. 1 is the face structure schematic diagram selecting the angle-bender of bar bending radius provided by the invention.
Fig. 2 is that this can select the angle-bender internal structure schematic diagram of bar bending radius.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the angle-bender selecting bar bending radius provided by the invention, comprise body 1, motor 2, first semicircular ring 8, housing 9, rotary handle 10, threaded rod 11, cylinder 13, rotating disc 14, central pin shaft 15, second semicircular ring 16 and motor output shaft 21.Described central pin shaft 15 is positioned at body 1 working face; Described motor output shaft 21 is connected with rotating disc 14 through central pin shaft 15; Described body 1 is provided with multiple semicircular ring, and multiple semicircular ring is all concentric with central pin shaft 15, forms warp rail between adjacent semicircular ring; Be provided with clamping device in described warp rail, described clamping device comprises housing 9, is provided with compact heap in housing 9, and compact heap is provided with rotary handle 10, and rotary handle 10 is connected with housing 9 threaded engagement; Be rotatably connected between described clamping device and rotating disc 14 retractor device; Described retractor device comprises threaded rod 11 and cylinder 13, and threaded rod 11 is connected by threaded engagement with cylinder 13, and cylinder 13 and rotating disc 14 are rotatably connected, and threaded rod 11 is connected with clamping device.
Because multiple semicircular ring forms multiple annular curved track, need to select different warp rails according to on-the-spot reinforcing bar 25 bending radius.Making threaded rod 11 extend or shorten by rotating rotating cylinder 12, allowing clamping device enter on above-mentioned selected warp rail, thus realizing the bending of different U-shaped reinforcing bar radius.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
