Description

Bar straightener
technical field:
the utility model relates to a kind of bar straightener.
background technology:
former mechanical type straightening fixed-length cutting machine is total, and reinforcing bar out enters this cylinder afterwards by biscuit frame, and suitably the adjustment screw of adjustment straightener cube, is fastened on straightener cube on different eccentric positions, to carry out straightening to different size or reinforcing bar of different nature.The scheme of straightening has Gaussian curve type, sinusoidal and cosine curve type, is applicable to different-diameter respectively, the reinforcing bar of different yield strength.After straightening polydisc reinforcing bar, straightener cube can produce wearing and tearing, now, should mend eccentric to ensure straightening effect.Straightener main transmission box and traction pressure roller, reduced motor speed by mechanical reduction gear in transmission case, and drive initiative compression roller (upper pressure roller) to rotate.During material loading, rotate an eccentric handle, pressure roller is lifted, by reinforcing bar through the V-type groove upper pressure roller and lower compression roller (by dynamic pressure roller), then rotate backward eccentric handle, pressure roller is put down, upper and lower two pressure rollers are in clamping reinforcing bar state.Material is pressed between two pressure rollers, is depended on the chucking power between pressure roller by the size of adjustment reinforcing bar strength.The connecting rod be connected with upper pressure roller machinery there is a spring to be attached thereto, this spring implements pressurization to upper pressure roller, the tractive force of pressure roller is directly proportional to pressure, therefore should select different spring pressures to different-diameter from the reinforcing bar of material, thus grips preferably and draw reinforcing bar.Meanwhile, for preventing the company when shearing from cutting phenomenon, when reinforcing bar is stopped by top, between reinforcing bar and pressure roller, obvious skidding should be able to be there is.Therefore the adjustment of spring pressure is the key that can straightener normally work.In transmission case, the double-slider mechanism of eccentric shaft drives tup to do the straight reciprocating motion of vertical direction, and in the square cutter platform of cutting mechanism, lower cutter is housed, when the cutting knife in the side's of being contained in cutter platform enters below tup, upper cutter is realized bar cutting work by hammering.After reinforcing bar is interrupted, square cutter platform resets by pull-rod spring.By the fixed length mechanism that bin is aligning cutting-off device, frame there is the sizing plate for fixed length, the good position of sizing plate in lacing wire of length adjustment as required, and adjust the pressure of lacing wire spring, make to be straightened reinforcing bar can push sizing plate and advance, and be cut off rear cutter platform at reinforcing bar again and can reset in time.When being pushed sizing plate advance by tune reinforcing bar and putting in place, sizing plate drives lacing wire to move, and the side's of dragging cutter platform enters below tup and realizes shearing.After shearing completes, square cutter platform resets by pull-rod spring.When reinforcing bar is cut off, open discharging by bin, after reinforcing bar falls, close immediately by bin, accept next root reinforcing bar.During by bin discharging, the length of opening the time is controlled by the time relay.The method error of traditional cut-out reinforcing bar is large, time-consuming, effort, and inefficiency, otch is irregular.
utility model content:
the purpose of this utility model is to provide a kind of bar straightener.
above-mentioned object is realized by following technical scheme:
a kind of bar straightener, its composition comprises: motor, described motor drives straightening drum, conical gear respectively by two V belt wheels, described conical gear is connected with gear C is coaxial, described gear C engages with gear A, described gear A is connected with gear B is coaxial, and described gear B engages with traction wheel, described conical gear is provided with crankwheel, the crank end of described crankwheel is provided with tup, fixed length pull bar is installed below described tup, described fixed length pull bar is provided with slip cutter platform, described fixed length pull bar is fixed with two Compress Springs, is provided with fixed length baffle plate in described fixed length pull bar one end.
beneficial effect:
1. to have modulation effect good for the utility model, cuts off the features such as accurate, easy to learn, rational in infrastructure, easy and safe to operate, otch is neat, error is little, performance is good.
the utility model has rational in infrastructure, the feature such as reliably easy and safe to operate, is applicable to the straightening of chicken coop, rabbit-hutch, building mesh sheet, various welding wire, leisure plate plugging wire Trimmed sums abnormity mesh sheet silk.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.In figure, 12 is reinforcing bar.
detailed description of the invention:
embodiment 1:
a kind of bar straightener, its composition comprises: motor 1, described motor drives straightening drum 2, conical gear 6 respectively by two V belt wheels, described conical gear and gear C, piece number: 5 coaxial connections, described gear C and gear A, piece number: 3 engagements, described gear A and gear B, piece number: 4 coaxial connections, described gear B engages with traction wheel 14, described conical gear is provided with crankwheel 7, the crank end of described crankwheel is provided with tup 8, fixed length pull bar 10 is installed below described tup, described fixed length pull bar is provided with slip cutter platform 13, described fixed length pull bar is fixed with two Compress Springs 9, is provided with fixed length baffle plate 11 in described fixed length pull bar one end.
