Below in conjunction with description of drawings the present invention is done further explanation.
A kind of stirrup bender of the present invention; Comprise: left cabinet, middle cabinet 3, right cabinet, discharging frame assembly 6, clutch box 7, decelerator 8, motor 9, foot accelerator clutch assembly 10, right end plate 11, holding pad 12, preceding beam assembly 13, cam swing assembly 14, protective cover 15, first member plate 16, frame 17, upper cover plate 18, curved cam 19, roller 20, tooth bar 21, tooth bar back-moving spring 22, hollow gear shaft 23, mandrel 24, dial assembly 25, cam collision block 26, driving lever collision block 27, driving lever 28, group slot 29, beam 30, adjustment nut 31, adjustment screw 32, adjusting rod 33, cotter pilotage 34, pivoted arm 35, dial 36, baffle plate 37; It is characterized in that: frame 17 left and right sides two parts combine and assemble; Upper cover plate 18 is arranged at the top, and first member plate 16, right end plate 11 are equipped with in two ends; Middle cabinet is fixed in frame 17 inner middle parts; Cabinet 3 both sides in the middle of left side cabinet, right cabinet are located at; Power transmission shaft end on clutch box 7, decelerator 8, the installation of motor 9 combine and assemble and the right end plate 11; Discharging frame assembly 6 is located on the frame 17, its trough places the cabinet top; Foot accelerator clutch 10 is located at the right end plate bottom: first member plate 16 is provided with cam swing assembly 14, protective cover 15.
Described a kind of stirrup bender has five cabinets, and middle cabinet 3 is fixed, and left cabinet and right cabinet are adjustable complete machine case.
Said left cabinet, middle cabinet 3, right cabinet are by curved cam 19, roller 20, tooth bar 21, tooth bar back-moving spring 22, hollow gear shaft 23 and place mandrel coaxial with it in its axis hole 24, dial assembly 25, cam collision block 26, driving lever collision block 27 and driving lever 28 to constitute, and the final drive shaft of curved cam 19 crosses in the dead eye of each curved cam 19 and crosses in left cabinet, middle cabinet, right cabinet; Mandrel 24 and tooth bar back-moving spring 22 are housed in the hollow gear shaft 23, and there are fork slot 29 and beam 30 and adjustment nut 31 in mandrel 24 lower ends.
Described dial assembly 25 is made up of adjustment screw 32, adjusting rod 33, cotter pilotage 34, pivoted arm 35 and dial 36, and wherein dial 36 is connected with described hollow gear shaft 23 keys, and pivoted arm 35 is connected with adjusting rod 33 usefulness cotter pilotages 34, makes that dial 36 angles are fine-tuning.
Described a kind of stirrup bender, upper cover plate 18 is arranged at frame 17 tops, and upper cover plate 18 is provided with the automatic feeding of inclination.
Described a kind of stirrup bender operation principle: motor 9 connection reducers 8, clutch 7; Drive is crossed in the final drive shaft of the curved cam 19 of left cabinet (1,2), middle cabinet 3, right cabinet (4,5); Each standalone chassis utilizes curved cam 19 to rotate and promotes tooth bar 21 rectilinear motions, and tooth bar 21 drives hollow gear shaft 23 and makes half circular motion.Each stirrup have five curved, so the combination bending machine has five cabinets, the brake forming of stirrup is accomplished in the curved cam of five cabinets interval that shares out the work successively.Reinforcing bar is by after curved, and cam collision block 27 is depressed driving lever 28, and the mandrel 24 that drives in the dial assembly 25 is accomplished the action of loosing core; Mandrel 24 descends, and makes workpiece slip over from mandrel 24 tops, thereby is curved next curved creating conditions; Repeat above-mentioned working procedure then, thus accomplish on every stirrup five curved.
Described a kind of stirrup bender frame is made up of left frame and right frame two parts, and first combine and assemble, screw are fastening, covers upper cover plate 18 and is put on the ground, power supply and gauge tap is connected, and connected ground protection block.Press gauge tap, whether inspection motor direction of rotation is correct, makes its idle running 5-10 minute.To lubricant housings filling lubricating oil, foot accelerator clutch makes its running and lubricated, turns round no abnormally can operate adjustment.
Open upper cover plate 18 earlier before the crooked work, adjust left cabinet according to the specification of the stirrup of want bending successively through stationary rack, adjust right cabinet again, the cabinet trip bolt of screwing after the adjustment carries out the exemplar bending.Curved good stirrup exemplar is carried out dimension control.After exemplar is qualified that the reinforcing bar length location-plate at two ends is fastening, can carry out normal crooked work.Single can operation during this machine bending work, the reinforcing bar of the fixed length that alignment is good is put into curved slot successively, can only put into a bar bending at every turn.The foot accelerator clutch plate promptly carries out bending work.The curved ditch at left side cabinet 1 and right crooked two ends of 5 while of cabinet, after the brake forming, the mandrel of left cabinet 1 and right cabinet 5 can descend automatically; Workpiece slips over from the mandrel top, the bending work after getting into, and left cabinet 2 and right cabinet 4 be the curved ditch in crooked two roads of while subsequently; The mandrel of left side cabinet 2 and right cabinet 4 descends automatically, and workpiece slips over from the mandrel top, the middle cabinet 3 last brake formings of accomplishing stirrup; Middle cabinet 3 mandrels descend, and workpiece ejects from mandrel 24 tops.Through foot accelerator clutch control, but the single-piece brake forming, but also continuous bend moulding, the stirrup of moulding falls from movable platform successively.
For realizing that a clamping accomplishes a plurality of curved actions on the stirrup continuously, be designed with especially that whenever curved once curved back mandrel descends automatically mechanical function, make workpiece slip over, so that the follow-up several curved action of continuous bend from the mandrel top.
During bar bending, if when factors such as rebar sizes change, bending the angle that has also and can change.The structural design of the dial assembly 25 bending hoop devices that described curved cam 19, tooth bar 21 transmissions, angle are fine-tuning makes the moment reinforcement angle to finely tune according to the variation of actual conditions, to guarantee the angle requirement of crooked stirrup.
The present invention is in the moment reinforcement operation, and mandrel 24 can descend automatically, makes workpiece slip over smoothly the side from it, realizes that a clamping is moulding, so the stirrup steady quality of moulding, the dimensional uniformity of bending finished product is good; The per hour brake forming of 1260 stirrups when being implemented in high speed, the per hour brake forming of 850 stirrups when low speed; And this machine is cheap, easy and simple to handle, can be adaptable across dissimilar construction sites.
