Description
Technical field
The present invention relates to a kind of building iron bender, relate in particular to eccentric eccentric throw and the design of relative accessory size in a kind of angle bender, belong to building machinery design and manufacturing technology field.
Background technology
Be widely used at present the angle bender in the construction, the length of its body is long, volume is large, weight is large, highlights the body clumsiness, and energy consumption is high, price is high, transportation is inconvenient, thereby cost performance is undesirable.Therefore building unit wishes to have small and exquisite, the cheap but also stirrup bender that can satisfy the reinforcing steel bar hoop bending needs of a kind of not only volume to apply in the construction.Researching and analysing the root that causes above-mentioned drawback, be not difficult to find that its eccentric eccentric throw design is unreasonable in the machinery, is the basic reason that causes the existing huge clumsiness of angle bender body.Eccentric eccentric throw design is excessive in the existing stirrup bender, and the torque that brings thus reductor is excessive and power is increased, and because eccentric throw is crossed the corresponding increase of ratio member that ambassador is correlated with, causes the bulky of whole machinery.Therefore design a kind of rational eccentric wheel eccentric throw and with the rational proportion size of its associated components be the key of stirrup bender smaller volume, weight saving.
Summary of the invention
Present angle bender body is huge in order to solve, the high many drawbacks brought of energy consumption, the invention provides a kind of building iron bender.
To achieve these goals, Bian of the present invention gets following technical scheme and implements: it comprises frame, motor, reductor, eccentric wheel, connecting rod, adjusting nut, frid, crane, pin, elevating lever, tooth bar, link stopper, central shaft, scratch diskette, gear shaft, gear, connecting pin, trough with straight angle, lever, reinforcing bar, bending hoop pin, it is characterized in that described eccentric eccentric throw a is designed between 60～70mm; The two-way flute length l=5/6 a of trough with straight angle; Bending radius r=0.7 a of scratch diskette; ɑ during 90 ° of angles of bending=(the 360 °/2r ∏ (d is the connecting pin diameter in the formula) of 2 a-l-d), ɑ ' during 135 ° of angles of bending=360 °/2r of 2 a ∏.Because the present invention has dwindled eccentric throw at the eccentric large eccentricity of traditional angle bender apart from the basis, thereby dwindled the eccentric throw reduction volume of twice at the length direction of body, in addition same the dwindling owing to the eccentric wheel eccentric throw of relative trough with straight angle length, thereby its range of movement is also being dwindled, make the length of body obtain further minimizing, and dwindling in the situation of body, because relative dimensions forms ratio, thereby the present invention can be settled at one go when the bending reinforcing bar.
The advantages such as the volume that the present invention has compact conformation, complete machine is little, lightweight, energy consumption is low, cost performance is good.

The specific embodiment
Shown in accompanying drawing 1,3,5, the eccentric throw a of eccentric wheel 4 is designed to 60mm, and make the two-way flute length of trough with straight angle 18 respectively equal 5/6 a, and select the respective diameters of bending hoop pin 21 according to the diameter of institute's bar bending 20, make the bending radius of scratch diskette 14 equal 0.7 a, simultaneously ɑ=(the 360 °/2r ∏ (d is the connecting pin diameter in the formula) of 2 a-l-d) selects modulus and the diameter of tooth bar 11, gear 16 under the condition of ɑ ' during 135 ° of angles of bending=360 °/2r of 2 a ∏ when satisfying 90 ° of angles of bending.Such as accompanying drawing 1,2,3, shown in 4, when reinforcing bar 20 needs 90 ° of angles of bending, the motor 2 that starts in the frame 1 drives reductor 3 rotations, when the limit on the right-right-hand limit position of the limit on the left position row of eccentric wheel 4 from Fig. 1 to Fig. 2, eccentric wheel 4 drivening rods 5, frid 7, trough with straight angle 18 is made the rectilinear motion of idle stroke, when the horizontal left end of trough with straight angle 18 can promote connecting pin 17 motion, connecting pin 17 band carry-over bars 11 are moving linearly to the right, tooth bar 11 promotes gear 16, gear shaft 15, scratch diskette 14, bending hoop pin 21 is done turning clockwise as shown in Figure 4, reinforcing bar 20 is at link stopper 12, do 90 ° of bendings under the acting in conjunction of bending hoop pin 21 and central shaft 13, thereby finish 90 ° bending operation.Shown in accompanying drawing 5,6,7,8, when reinforcing bar 20 needs 135 ° of angles of bending, the pin 9 of stepping on lever 19 drive elevating levers 10 and being fixed on the elevating lever 10 moves upward, pin 9 jack-up cranes 8 and the frid 7, connecting rod 5, the trough with straight angle 18 that are fixedly connected on the crane 8 make connecting pin 17 enter vertical lower end of trough with straight angle 18.During the limit on the right-right-hand limit position of the limit on the left position row of eccentric wheel 4 from Fig. 5 to Fig. 7, eccentric wheel 4 drivening rods 5, frid 7, trough with straight angle 18, connecting pin 17 band carry-over bars 11 are moving linearly to the right, tooth bar 11 promotes gears 16, gear shaft 15, scratch diskette 14, bending hoop pin 21 and does turning clockwise as shown in Figure 8, reinforcing bar 20 is done 135 ° of bendings under the acting in conjunction of link stopper 12, bending hoop pin 21 and central shaft 13, thereby finishes 135 ° bending operation.Because the present invention is when 90 ° of angles of bending, eccentric wheel 4 drivening rods 5 one section trough with straight angle 18(l-d that passed by) idle stroke, thereby the stroke of tooth bar 11 is 2a-l-d; When 135 ° of angles of bending, the stroke that eccentric wheel 4 drivening rods 5, tooth bar 11 are passed by tooth bar 11 is 2a, this shows: as long as design accurately horizontal flute length of trough with straight angle 18,90 ° of angles of bending and 135 ° of angles just can be realized, and do not need to increase the adjusting device of trough with straight angle 18 horizontal flute length, the length space of therefore having saved body.Because the present invention is when the bending reinforcing bar, frid 5 exists the motion process of 2 times of eccentric throws, thereby when its space of design, must be at the right-hand member of frid 5 and be fixed on to leave between tooth bar seat 10 left ends on the frame and allow the locus of its motion, the eccentric throw of this position and eccentric wheel 4 is made substantial connection, eccentric throw is larger, the increase of the necessary twice in its locus of leaving, otherwise will cause in frid 5 motion processes and the bump between the tooth bar seat 10.Facts have proved that only when the eccentric throw of eccentric wheel 4 designed between 60～70mm, this mechanical volume space minimum, that intensity is best, mechanism leaves was the most reasonable.Because the present invention is designed to 5/6 a with the two-way flute length l of trough with straight angle 6, thereby can make bending angle ɑ=(2 a-l-d) 360 °/2r ∏=90 ° of establishments (d is the connecting pin diameter in the formula).Rotation adjusting nut 6 can be made trace with respect to the position of trough with straight angle 18 to connecting pin 17 and regulate.
