Description
Technical field
The utility model relates to reinforcing bar process equipment, specifically relates to steel bar stretching straightening shear.
Background technology
Steel bar stretching straightening shear has frame, has machine straightening device and stretching device in frame, when screwing steel bars, first need reinforcing bar to stretch, and then straightening.
In described frame, also have motor and decelerator, motor is connected with transmission device with decelerator.
Described stretching device is such: it comprises multiple upper roller wheels and multiple lower roll wheel, multiple upper roller wheels and multiple lower roll wheel are arranged in frame in tandem, lower roll wheel is below upper roller wheel and be staggered and be arranged in frame, reinforcing bar is through between multiple upper roller wheels and multiple lower roll wheel, track route is the route of " W " shape, and the pulling force in dependence between roller wheel and lower roll wheel is by steel bar stretching.
Described lower roll wheel transmission device connection reducer, dynamic lower roll wheel just can ensure the stretching of reinforcing bar.
Motor is connected with transmission device with decelerator, lower roll wheel transmission device connection reducer, in prior art, these transmission devices are all that belt connects, connect the shortcoming with low precision with belt, in prior art, because multiple lower roll wheel speed ratios are unreasonable, exist larger, the inefficient shortcoming of pulling force in addition.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, and the steel bar stretching straightening that a kind of precision is higher, efficiency is high shear is provided---the steel bar stretching straightening shear of chain drive.
The technical solution of the utility model is: the steel bar stretching straightening shear of chain drive, comprise frame, and in frame, there is machine straightening device and stretching device, in described frame, also have motor and decelerator, motor is connected with transmission device with decelerator; Described stretching device is such: it comprises multiple upper roller wheels and multiple lower roll wheel, multiple upper roller wheels and multiple lower roll wheel are arranged in frame in tandem, lower roll wheel is below upper roller wheel and be staggered and be arranged in frame, lower roll wheel transmission device connection reducer, is characterized in that: described lower roll wheel chain connection reducer.
Say further, in described frame, also there is propelling, extractor, described propelling, extractor is that two relative running rollers are arranged in frame by roller frame, wherein at least one running roller connecting power device, two relative gap positions of running roller are exactly the charging aperture of reinforcing bar, and described running roller connecting power device connects by chain.
Say further, after described multiple lower roll wheels, one is 1.18-1.22 with previous speed ratio.
Best, after described multiple lower roll wheels, one is 1.2 with previous speed ratio.
The beneficial effects of the utility model are: such reinforcing steel bar straightening cutter has the more accurate advantage of adjustment; After described multiple lower roll wheels, one is 1.18-1.22 with previous speed ratio, can reach the advantage that production efficiency is high, power loss is few; After described multiple lower roll wheels, one is 1.2 with previous speed ratio, has advantages of best results.
Brief description of the drawings
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Wherein: 1, frame 2, stretching device 3, motor 4, decelerator 5, upper roller wheel 6, lower roll wheel 7, chain 8 advance, extractor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, 2, the steel bar stretching straightening shear of chain drive, comprises frame 1, has machine straightening device and stretching device 2 in frame 1, also has motor 3 and decelerator 4 in described frame 1, and motor 3 is connected with decelerator 4 use transmission devices; Described stretching device is such: it comprises multiple upper roller wheels 5 and multiple lower roll wheel 6, multiple upper roller wheels 5 and multiple lower roll wheel 6 are arranged in frame in tandem, lower roll wheel is below upper roller wheel and be staggered and be arranged in frame, lower roll wheel transmission device connection reducer, is characterized in that: chain 7 connection reducers for described lower roll wheel.
Say further, in described frame, also there is propelling, extractor 8, described propelling, extractor 8 is that two relative running rollers are arranged in frame by roller frame, wherein at least one running roller connecting power device, two relative gap positions of running roller are exactly the charging aperture of reinforcing bar, and described running roller connecting power device connects by chain.
Say further, after described multiple lower roll wheels, one is 1.18-1.22 with previous speed ratio, and inventor is through exerting pressure, and effect is better like this.
Best, after described multiple lower roll wheels, one is 1.2 with previous speed ratio.
For example, before the speed of first lower roll wheel be 1, the speed of second lower roll wheel is that the speed of 1.2, the three running rollers is 1.44, the most laborsaving like this, inventor is through overtesting, best results like this.Described speed is the linear velocity at running roller contact reinforcing bar position.The diameter those skilled in the art that improve adjustment driving wheel and driven pulley are easy to realize, as long as meet in a word above-mentioned requirements.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed in the scope of the claims of the present utility model.
