Description
Technical field
The utility model relates to a kind of pay-off of automatic wire straightener, particularly with the back material feeding pressing wheel device of the automatic wire straightener of handle compacting part.
Background technology
At present, most of automatic wire aligning cutting-off device model that China straightener manufacturer is produced is CT 4-8, CT 4-12, CT 4-14 type, that the most generally uses on the construction market is CT 4-14 type, because of the drive mechanism difference of this model straightener, will the back feeding, reload, material-pouring device design puts in place.In the actual use of straightener, specification because of the wire rod reinforcing bar, the difference of diameter, when reloading installation, the wire rod reinforcing bar that has in the straightener straightening drum must be pulled out, the installation of just reloading, because of this 4-14 type straightener can not reverse, in actual straightening wire rod process, the wire rod reinforcing bar can only be pulled out discharging forward, when reloading installation, the wire rod reinforcing bar can't be poured out in straightening drum automatically, in the time of need reloading, machine can only be stopped, straightening drum straightening piece screw is back-outed, also preceding pinch roller clamping screw to be back-outed simultaneously, again reinforcing bar manually firmly be pulled out backward.When filling with substance needs straight 1-1.5 rice is turned round in one section craft of reinforcing bar head, with preceding pinch roller with the word breach that warps out, again reinforcing bar is inserted in the straightening drum, pull with hand that change on the straightening drum limit, tear open on the limit, after the reinforcing bar head being inserted into the traction race, again front spring pinch roller screw is tightened with hand, simultaneously straightening piece pressure screw is adjusted, can start shooting, in actual use, bring very burden to operating personnel, be absolutely unsafe, time-consuming.
Because of above-mentioned situation, the professional straightener of China's part manufacturer has increased that back feeding is drawn, reloaded, material-pouring device on original 4-12 type.In design, basic structure with reference to former 4-14 type front haulage wheel, this structure traction wheel bearing block up and down manufactures cubic type, and a round bearing hole need be opened in the centre, is used to install bearing and axle and gear roller assembly etc.Profile shaft bearing sleeve both sides, four directions must have two parallel grooves, use this square bearing seat must on frame, increase the long iron plate in plane of a block length 1500mm, wide 500mm, thick 20mm, be used to install and fix straightening drum both sides bearing block and front and back traction wheel, cubic profile shaft bearing square thickening iron prop frame.On the thick iron plate at charging position behind the straightening drum, weld the square long 400mm of two block lengths, wide 120mm, thick 35mm thickening straight beam iron prop, both sides in the cubic type straight beam iron prop are split into tongue, be used to install and fix back feeding traction wheel metal (upper cover, on the rectangle iron prop frame of back, increase by a block casting iron and connect the fixing thick pressing plate in iron prop frame both sides, in the middle of pressing plate and square bearing cover, join a short pressing spring, open a screw hole in the middle of the cast iron pressing plate, above pressing plate, join a turnbuckle handle, be used to compress the short compression spring that square bearing puts, be furnished with bearing in the middle of the square bearing cover, axle, traction is the feeding roller initiatively, driven gear is an one.Is furnished with following initiative traction wheel square bearing cover in the square iron prop frame, be furnished with bearing, axle, active feeding roller, main driven wheel in the bearing holder (housing, cover), main driven wheel cooperates with the top driven gear, is furnished with chain pitch wheel on the driving shaft, connects as one by chain and front haulage wheel spindle sprocket.When installation is reloaded, pressing plate turnbuckle handle on the rear haulage wheel is back-outed, steel bar end is inserted in the back feeding traction rollers groove, again the pressing plate turnbuckle is tightened, under the pressure of spring, reinforcing bar is compressed, start the machine, back feeding roller makes traction wheel rotate forward under the transmission of motor and reduction gearing, chain, with and reach automatically feed purpose, when needs reload, the machine two-direction switch is left backward the traction wheel counter-rotating, reinforcing bar is pulled out, with and reach reload, the purpose of batch turning.
Machine is found following deficiency in the actual production use:
Less than 1:
Because of going up the fixing needs of feeding traction wheel square groove bearing block in the back, must on this frame, increase the plane iron plate of a block length 150mm, wide 500mm, thick 20mm, increase feeding traction shifting roller square bearing seat in the back position of iron plate again the rectangle iron prop frame of usefulness is installed, two tongues need be opened in both sides in the iron prop frame, it connects the processing technology more complicated, need many professed machine equipment just can machine, cause production cost too high.
Less than 2:
Use spends blue handle to tighten the method for compression spring.Need the manual blue handle screw of spending on will back pinch roller compression spring tighten during installation, because of the reason of the diameter configuration of spring, spring diameter is too thick, causes to spend blue tension, can't twist; Join tinyly as spring diameter, spring pressure is not enough, and back material feeding pressing wheel can't compress reinforcing bar, causes reinforcing bar to be difficult to enter in the straightening drum automatically.Because of the back material feeding pressing wheel tightens by craft or loosens and spend blue screw handle in actual use, wire rod reinforcing bar per ton on average needs more reloader, feeding, batch turning 8 one 12 times, because of this method can not disposablely compress the back pinch roller or loosen, bring very big inconvenience to operation.
Less than 3:
Square moves up and down after bearing holder (housing, cover) groove and the thick iron plate tongue of frame connect, during machine works, upper pressure wheel and bearing holder (housing, cover) are under the reversal interlocking relay of straightening drum wire rod, simultaneously, square bearing cover groove and thick iron plate tongue connector tongue produce the pulling force skew, noticeable wear, excesssive gap appear in upper pressure wheel square bearing cover both sides groove, ftracture, cause up and down that traction wheel swings, is offset, so, the traction wheel roller shaft is not worked on same axis up and down, and traction wheel gear and upper pressure wheel and mainshaft gear are badly damaged about causing simultaneously.
