Description

Reinforcing bar prestressing, aligning and cutting off machine

The utility model relates to a kind of wire rod processing or processing machine.

In builing industry, the aligning of bound reinforcing bar, cut-out operation, for guaranteeing the reinforced concrete member quality, also must be to reinforcing bar prestressing, normally to reinforcing bar tensioning in advance or again reinforcing bar is carried out tensioning behind placing of concrete, the machinery of being engaged in above-mentioned operation emerges, but the complex structure that has, bulky, cost an arm and a leg, what have can only align and cut off, can not prestressing.

The purpose of this utility model is to overcome the weak point in the above-mentioned background technology, and a kind of reinforcing bar prestressing, aligning and cutting off machine of the economical and efficient that can comprehensively process reinforcing bar are provided, it extensively is suitable for hand building site and reinforced concrete member manufactory.

The purpose of this utility model reaches by taking following proposal:

1, establishes frame 17, two groups of horizontal pressure rollers before and after in frame, establishing, the rotating speed of preceding group pressure roller suitably is higher than the rotating speed of back group pressure roller, the working diameter of driving wheel 4 is less than by the working diameter of driven pulley 3 in the back group of pressure roller of its drive in the group pressure roller promptly, or the working diameter of preceding group of pressure roller is greater than the working diameter of back group pressure roller; Establish a pair of guide wheel 1 in frame rear end reinforcing bar entrance;

2, establish a plurality of radially circular arc grooves on the pressure roller, the arc size of each groove is different, but all pressure rollers on the same group are of similar shape size; The two groups of pressure rollers in front and back can be unified to move axially with roller frame 2, so that make the arc groove that needs usefulness aim at the reinforcing bar inlet; Last pressure roller has the lift adjustment bolt;

3, establish motor and common material cutting mechanism at frame front, its horizontal main shaft left end has big belt pulley 8 and clutch 7 thereof, and right-hand member has eccentric shaft 6; Motor drives big belt pulley, big belt pulley drive the small belt pulley be contained on the axle 19, and the pinion 18 coaxial with small belt pulley drives gear wheels 20, and gear wheel is other its clutch 21, and be coaxial with driving wheel and gear wheel one of in the preceding group of pressure roller; Adopt gear drive between the pressure roller, adopt chain drive between the driven wheel 4,3; Clutch all adopts embedded;

4, before frame, establish slightly Y-shaped vertical unloading rack, this has several pin, several mouthfuls circular arc charge plate 14 up distributes on the not high vertical pipe that is supported by the frame pin overhead, frame pin top left side is stretched out curved boom, fixing left guide plate 10 at the curved boom top, right guide plate 12 and two support plates 13 can in horizontal plane, swinging, the right-hand member of support plate is connecting Dump gate 15, Dump gate constitutes a left side before reinforcing bar is cut off, bottom between the right guide plate, its front end is connecting spring, on a left side, establish the collision block that plays the scale effect 11 that can slide therein between the right guide plate, the collision block top is wire rope fixedly, several wire guide plates that can pass wire rope 9 are arranged at guide plate top, a left side, a left side, several horizontal deflector rolls 16 are arranged at the top between the right guide plate, and the reinforcing bar of being aligned can withstand collision block between deflector roll and Dump gate.

5, if can handle the mechanism and the shedding mechanism of two clutches synchronously, the thin thick seben 22 of back segment of leading portion is housed in the clutch 21 of importing power for prestressing and aligning, when clutch is in bonding state, seben light filling bar plug is in clutch, when thick section of seben begins to fill in clutch, clutch enters released state immediately, simultaneously, give blank and draw back in the clutch 7 of Dump gate input power the thin seben 5 of the thick back segment of leading portion is housed, when prestressing and aligning, this clutch should be in released state, and promptly the thick slug of this seben is in this clutch, when blank, clutch 21 separates earlier, when filling in clutch 7 fully Deng seben 5 light filling bars, the just combination of this clutch, material cutting mechanism is started working, then, when getting back to the summit, pass through connecting rod by eccentric shaft with cutter, wire rope and assembly pulley draw back Dump gate, and the reinforcing bar of cut-out is dropped on the charge plate; Two sebens all have the Long Circle endoporus, and its rear portion is the bolt that is with spring; Based on the seben feature, push collision block by the reinforcing bar front end, collision block spurs two sebens simultaneously and fills in forward in the corresponding clutch by wire rope and assembly pulley, can realize handling synchronously by working programme the requirement of two clutches.

The utility model contrast background technology has following useful effect: the rotating speed of group pressure roller suitably was higher than the innovation thinking of back group pressure roller rotating speed before 1, utilization made, and adopted above-mentioned simple and practical scheme to solve the prestressing problem of reinforcing bar effectively; 2, compact conformation, to account for the place little, cost of production is low; 3, rational in infrastructure, reliable operation, as long as high-effective and labour-saving is after inserting guide wheel and pressure roller and start with steel bar end, just can carry continuously, aligning, prestressing, cut-out, discharging, till a dish reinforcing bar is processed to meet the prestressed reinforcement of technical requirements.

Description of drawings: Fig. 1, reinforcing bar prestressing, aligning and cutting off machine front view; Fig. 2, reinforcing bar prestressing, aligning and cutting off machine vertical view; Fig. 3, unloading rack left view.

The utility model is done further narration below in conjunction with the accompanying drawing illustrated embodiment:

This machine shown in the drawings is in bar straightening, prestressing and has just finished the moment that is about to cut-out, at this moment, clutch 21 still still separates in conjunction with, clutch 7, and eccentric shaft is in 90 ° the position of turning clockwise from last summit, Dump gate is still closed, and steel bar end withstands on the collision block.

When steel bar end continued to move forward, thick section of seben 22 began to fill in clutch 21, and this clutch separates immediately, prestressing and aligning work stop, the power of conveying steel disappears, but the inertia of machine still makes steel bar end advance, and fills in clutch 21 fully until thick section of seben 22, meanwhile, the light filling bar of seben 5 is filled in clutch 7, but must fill in fully, the just combination of this clutch, after its combination, cutter is descending, and eccentric shaft also is rotated down, and Dump gate is opened thereupon, after blank is finished, cutter is up, and eccentric shaft rotates up, and Dump gate is also closed thereupon, the finished product reinforcing bar is fallen on the charge plate, two sebens are return simultaneously immediately, and clutch 7 separates earlier, clutch 21 back combinations, collision block is pulled back thereupon, and work goes round and begins again.The reinforcing bar scale is by changing the position of collision block on wire rope, and the diverse location that the fixing collision block of wire rope is parked between left and right guide plate is realized.
