Abstract
The utility model relates to reinforcing steel processing equipment, in particular to a reinforcing steel stretching device and a reinforcing steel stretching, aligning and cutting machine. The reinforcing steel stretching device comprises a rack, wherein a plurality of first idler wheels are arranged on the front and the rear of the rack, and is characterized in that the first idler wheels are connected with a power source, the rotating speed of the first idler wheels positioned at the rear of the rack is greater than the rotating speed of the first idler wheels positioned at the front of the rack, a driven wheel is arranged between each two adjacent first idler wheels, and each driven wheel is provided with a vertically-sliding adjusting device on the rack. The reinforcing steel stretching, aligning and cutting machine comprises the reinforcing steel stretching device. Because the reinforcing steel stretching device has the above technical characteristics, the reinforcing steel stretching device and the reinforcing steel stretching, aligning and cutting machine have the advantages of simple structure and small noise.
Description
Technical field
The utility model relates to the reinforcing bar process equipment, specifically relates to steel bar stretching device and steel bar stretching aligning cutting-off device.
Background technology
The reinforcing bar of architectural use, often adopt cold drawn, to eliminate prestressing force; The equipment of stretching reinforcing bar is steel bar stretching device and steel bar stretching aligning cutting-off device, the steel bar stretching device reinforcing bar that can only stretch, and function ratio is more single; And the steel bar stretching aligning cutting-off device is stretching, straightening, blocks the machine into one, and the steel bar stretching device is parts of steel bar stretching aligning cutting-off device, and the steel bar stretching device can only be finished the operation of stretching.In the prior art, the structure of steel bar stretching device is such: it has a frame, be provided with the draw-gear of a band driving wheel in the frame, frame is provided with a plurality of driven rollers, the reinforcing bar of front twines through driving wheel, and the reinforcing bar of back twines through driven roller set, under the traction of driving wheel, reinforcing bar reaches the effect of stretching, and such stretching device has complex structure, shortcoming that noise is big.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and a kind of simple in structure, steel bar stretching device that noise is little and steel bar stretching aligning cutting-off device simple in structure, that noise is little are provided.
The technical scheme of the utility model steel bar stretching device is: the steel bar stretching device, comprise frame, first roller that has a plurality of front and back to arrange on the frame, it is characterized in that: described a plurality of first rollers are connected with power source, are positioned at the rotating speed of first roller of frame back greater than the rotating speed of first roller that is positioned at the frame front.
Further say, in the middle of described two first rollers, be provided with driven pulley.
Say that further described driven pulley has the adjusting device that slides up and down in frame.
The technical scheme of the utility model steel bar stretching aligning cutting-off device is: the steel bar stretching aligning cutting-off device, comprise the steel bar stretching device, and the steel bar stretching device has above-mentioned technical characterictic.
The beneficial effects of the utility model, such steel bar stretching device and steel bar stretching aligning cutting-off device have advantage simple in structure, that noise is little.
Description of drawings
The structural representation of Fig. 1 the utility model steel bar stretching device.
Wherein: 1, frame 2, first roller 3, driven pulley 4, adjusting device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the steel bar stretching device comprises frame 1, first roller 2 that has a plurality of front and back to arrange on the frame 1, it is characterized in that: described a plurality of first rollers 2 are connected with power source, are positioned at the rotating speed of first roller of frame back greater than the rotating speed of first roller that is positioned at the frame front.
Described a plurality of first roller 2 is connected with power source, and this power source can arrange motor in frame, drives first roller, and first roller that is positioned at the frame back switches through the bigger motor of speed, can realize the effect that rotating speed is high; Also the opposite side of passable frame arranges transmission devices such as chain, same chain of a plurality of first roller, 2 usefulness drives, select the sprocket wheel of suitable connection first roller 2, also can reach the purpose of different rotating speeds (being positioned at the rotating speed of first roller of frame back greater than the rotating speed of first roller that is positioned at the frame front), the similar techniques scheme can be designed many.
The rotating speed of first roller of back greater than first roller that is positioned at the frame front rotating speed, the roller of the back reinforcing bar that will stretch like this, play the purpose of this utility model, maximum adjusting range is set, can control before and after the rotating speed ratio of first roller, also just guarantee within the scope of extensibility, to make it to be no more than the scope of national regulation.
Further say, in the middle of described two first rollers, be provided with driven pulley 3.
Like this, reinforcing bar is in the process that stretches, and what can twine is more, and the path is longer, and resistance is more, more is conducive to the stretching of reinforcing bar.
Say that further described driven pulley has the adjusting device 4 that slides up and down in frame.
Like this, can adjust adjusting device at the reinforcing bar of different-diameter, have and use advantage more easily.
The technical scheme of the utility model steel bar stretching aligning cutting-off device is: the steel bar stretching aligning cutting-off device, comprise the steel bar stretching device, the steel bar stretching device comprises frame again, first roller 2 that has a plurality of front and back to arrange on the frame 1, it is characterized in that: described a plurality of first rollers are connected with power source, be positioned at the frame back first roller rotating speed greater than first roller that is positioned at the frame front rotating speed.
Further say, in the middle of described two first rollers, be provided with driven pulley.
Say that further described driven pulley has the adjusting device that slides up and down in frame.
