Description
Technical field
The present invention relates to a kind of wire feeder device of wire rod aligning cutting-off device, particularly automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus.
Background technology
The device of fixing, move up and down of traction wheel and bearing holder (housing, cover) is one of vitals on the automatic wire aligning cutting-off device.The wire rod straightener that the most manufacturers of present China are produced is 4-8,4-12,4-14 type, usually by the motor part, and the under drive gear device, wire feeder device, the straightening part, cutting out section is formed.Wherein wire feeder device presses traction wheel and main shaft traction wheel to form by preceding going up.By driven by motor deceleration belt pulley, reduction gearing, drive the conveyance gear axle by reduction gearing again, the conveyance gear axle is furnished with the traction wire rod and carries initiatively preceding traction wheel down.Passive conveying roller axle mentions that by the limit on both sides on the driving shaft wheel drives, on press traction wheel to drive by the upper pressure wheel gear shaft.When carrying the wire rod reinforcing bar, the steel plate clamping screw on the upper pressure wheel axle sleeve is tightened, last simultaneously pressure traction wheel is pressed on wire rod in the middle of the delivery wheel roller groove, under the driving of motor and gear, produce towing tension, make wire rod be fed forward, thereby reach the purpose that traction is carried.In order to solve the difference of straightener straightening gauge or diameter of wire, for this reason, preceding last pressure traction wheel and bearing holder (housing, cover), last conveyance gear assembly one cover, must design has enough spaces that moves up and down.Traction wheel diameter and the active of drawing up and down on the wheel shaft simultaneously, ring gear diameter is subjected to the restriction of straightening discharging speed, it is much smaller to drive reduction gearing than gearbox, cause traction wheel pressing shaft and gear design to be installed with axle shaft gear axially parallel in the gearbox, so, can only increase the cover gap bridge limit identical on gearbox driving shaft next door and mention wheel with the traction rollers diameter, thereby reach the identical rotating speed of traction wheel up and down, because the limit that increases mentions that wheel diameter is subjected to the restriction of casing size, can only will carry the wheel pressing shaft bearing to make cubic type, a round bearing hole is opened in the centre, is used to install bearing and axle and gear, the roller assembly.Profile shaft bearing sleeve both sides, four directions must have two parallel grooves, are connected with casing square opening tongue.It is one that upper pressure wheel square bearing cover and gear-box gear cooperate.There is a short arc steel plate square bearing cover top, a screw pressing plate is joined in the steel plate top, there is a turnbuckle handle pressing plate top, be used to compress steel plate, the short arc steel plate compresses the square bearing cover again, with and regulate the space between the traction wheel up and down, reinforcing bar is applied suitable pressure, reach the purpose of traction feeding.
This automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus has the following disadvantages in actual production and use:
Reduction gearing diameter on the said machine casing main shaft is bigger, the upper pressure wheel axle can not be installed on same axis with deceleration mainshaft gear axle, must increase by a cover limit and hang the gap bridge reduction gearing, simultaneously the upper pressure wheel bearing holder (housing, cover) can only be designed to cubic type, must on casing, open one rectangular mouthful, the square hole both sides need process two parallel tongues, two grooves are opened on square bearing cover both sides, be used for fixing and install the wheel pressing shaft bearing sleeve, casing and square bearing cover process by cast member, processing technology is complicated, and cost is higher.
During straightener work, upper pressure wheel and bearing holder (housing, cover) are under the reversal interlocking relay of straightening drum wire rod, profile shaft bearing sleeve groove both sides, four directions and casing connector tongue produce the pulling force skew, upper pressure wheel square bearing cover both sides groove is easy to wear, cracking,, excesssive gap, cause up and down that traction wheel swings, is offset, the traction wheel limit mentions that wheel and upper pressure wheel and mainshaft gear are badly damaged about making, make machine be difficult to bar straightening, and institute's reinforcing bar that accesses appears to running on one side, be difficult to enter automatically the phenomenon in the straightener runway scale groove, the machine cisco unity malfunction.
Profile shaft bearing size in four directions own is restricted, and causes the short arc steel plate length that compresses usefulness shorter, does not have enough elastic spaces that moves up and down, and the upper pressure wheel bearing holder (housing, cover) moves up and down the space also to be reduced.When installation, start; steel bar end can't need shutdown that steel plate is tightened up a screw and spend blue handle to back-out automatically with preceding upward traction wheel jack-up, will go up the lower pressure wheel spade with a word bottle opener and open certain space; could install in the middle of manually steel bar end being inserted the upper pressure wheel groove, time-consuming, dangerous.Simultaneously, because curved plate pressure is not enough, when back blowing disk wire rod reinforcing work only remained 1-3 rice to the end, reinforcing bar was under the high speed rotation of straightening drum, and obviously " rope skipping of rolling about " phenomenon appears in machine afterbody reinforcing bar tail, is absolutely unsafe.For this reason, must shut down straightening piece pressure screw is loosened, sets level, reinforcing bar could be remained tail and transfer, but tail still can not reach the straightening effect.
Summary of the invention
The object of the present invention is to provide a kind of automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus.
This automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus is that reinforcing bar traction wheel and traction wheel bearing holder (housing, cover) move up and down device automatically on the automatic straightener of wire rod, and going up wherein presses the traction wheel limit to hang that fixed rack structure is simple, processing is simple, durable, production cost is low.
Technical scheme of the present invention is:
Automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus comprises that forming pressure traction wheel limit by upper pressure wheel bearing holder (housing, cover), middle brace rod, fixed cover hangs fixed mount; The upper pressure wheel axle; Wherein: an end of middle brace rod is fixedlyed connected with the upper pressure wheel bearing holder (housing, cover), and the other end of middle brace rod is fixedlyed connected with straight beam in the frame by fixed cover.
Automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus, wherein: also comprise and press traction wheel, the dome post, last pressure traction wheel is fixedly sleeved in the upper pressure wheel bearing holder (housing, cover), one end of dome post is fixedlyed connected with the upper pressure wheel axle, the dome post other end contacts with the upper pressure wheel bar steel plate, and an end of upper pressure wheel bar steel plate is put the beams in place with frame and is connected, and the other end of upper pressure wheel bar steel plate links to each other with hand clamping screw.
Automatic wire rod aligning cutting machine reinforcing wire traction wheel apparatus, wherein: fixed cover inside has the limit to hang fixed screw middle brace rod is fixed in the frame on the straight beam, one end of upper pressure wheel bar steel plate is put the beams in place with frame by the bar steel plate fixed cover and is fixedlyed connected, hand clamping screw passes the frame upper beam and is fixed on frame by clamping nut and puts the beams in place, and fixedlys connected with screw handle in hand clamping screw upper end.
