Description
Technical field
A kind of bar cutting device of the utility model, for section bars such as shear reinforcements.
Background technology
Reinforcing bar is that a kind of output is large, and purposes is wide, steel wide in variety, especially applies very wide in building and mechanical processing industry.Steel ring is generally cut off in its joint after shaping for flat bar bending, and is welded together at its two ends.On Vehicles Collected from Market, the device cutting off reinforcing bar mainly adopts pneumatic means or hydraulic means, and such device is expensive, and maintenance difficulty is large, and fault rate is high, especially for small mechanic factory workers, to use and uneconomical.Some the mechanical clipping apparatus existed, structure is too complicated, and production efficiency is not high, makes the difficult quality guarantee of product.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of bar cutting device, and its structure is simple, and efficient work is stablized.
The technical scheme that the utility model is taked is:
A kind of bar cutting device, comprise drive sprocket, by movable sprocket, power transmission shaft, tightener sprocket, described drive sprocket is arranged on cam drive axle, is describedly arranged on power transmission shaft by movable sprocket, and tightener sprocket is arranged on chain tensioner spindle, described power transmission shaft is symmetrically installed with two cranks, each crank is connected with a connecting rod, and connecting rod is connected with Cutter apron, and described Cutter apron is provided with cutting knife, Cutter apron is arranged on guide rail, and guide rail is provided with block.
Described block is fixedly mounted on guide rail by two screws.
Described drive sprocket and cam coaxial.
A kind of bar cutting device of the utility model, comprises offset slider-crank mechanism, and this offset slider-crank mechanism is installed in the two ends of power transmission shaft symmetry, to ensure the stress balance of power transmission shaft.Utilize the quick return characteristic of offset slider-crank, when the cutting knife speed on Cutter apron of being arranged on is maximum, reinforcing bar is cut off.
This bar cutting device is connected with indexing mechanism with by movable sprocket by drive sprocket, and reinforcing bar is cut off by gap fast that can be implemented in indexing mechanism interval.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of bar cutting device, comprises drive sprocket 6-1, by movable sprocket 6-2, power transmission shaft 6-3, tightener sprocket 6-4.
A kind of bar cutting device of the utility model, comprise drive sprocket 6-1, by movable sprocket 6-2, power transmission shaft 6-3, tightener sprocket 6-4, described drive sprocket 6-1 is arranged on cam drive axle 2-6, describedly be arranged on power transmission shaft 6-3 by movable sprocket 6-2, tightener sprocket 6-4 is arranged on chain tensioner spindle 6-5, described power transmission shaft 6-3 and chain tensioner spindle 6-5 is installed in frame, described power transmission shaft 6-3 is symmetrically installed with two crank 6-6, each crank 6-6 is connected with a connecting rod 6-7, a connecting rod 6-7 is connected with a Cutter apron 6-8, a Cutter apron 6-8 is provided with a cutting knife 6-9, each Cutter apron 6-8 is arranged on a guide rail 6-10, guide rail 6-10 is arranged in frame, guide rail 6-10 is provided with block 6-11, block 6-11 front and back position can be finely tuned according to lopping diameter, block 6-11 is fixed on guide rail 6-10 by two screws after regulating.
A kind of bar cutting device of the utility model, comprises offset slider-crank mechanism, has quickreturn characteristics, and offset slider-crank is installed in power transmission shaft 6-3 two ends symmetry, ensure that two ends stress balance in shear history.
Described drive sprocket 6-1 and cam coaxial, ensure that the intermittent movement of the quick return of shear and pay-off can precision-fit all the time, cut off rapidly by reinforcing bar in the interval of feed mechanism.
Operation principle of the present utility model is as follows: according to the size of formed reinforcing steel bars, and guide rail 6-10 adjusts the position of block 6-11, is fixed on guide rail 6-10 by block 6-11 after adjustment by two screws.The power transmission shaft 6-3 of this shear is connected with the power transmission shaft 2-6 of feed mechanism 1-2 with by movable sprocket 6-2 by drive sprocket 6-1, ensures that the power transmission shaft 6-3 of shear and the power transmission shaft 2-6 of feed mechanism 1-2 remains synchronized movement.When feed mechanism 1-2 realizes interval, the Cutter apron 6-8 speed in the slider-crank mechanism of this shear 1-6, close to maximum, is arranged on cutting knife 6-9 on Cutter apron 6-8 and block 6-11 and forms a Simple scissors mechanism, fast by bar cutting.
