Abstract
The utility model is a sizing straightening device for a reinforcing bar hoop bending machine. An alveated straightening wheel (10) and an adjustable pressing wheel (9) are mounted on the base (1); the sizing straightening device further comprises an upper sizing wheel (5) and a lower sizing wheel (7) which are tangent to each other and placed at the front ends of the alveated straightening wheel (10) and the adjustable pressing wheel (9); wherein, the upper sizing wheel (5) is mounted on a upper sizing wheel shaft (4) through a needle bearing; the lower sizing (7) is mounted on a lower sizing wheel shaft (6) through a needle bearing; both the upper sizing wheel shaft (4) and the lower sizing wheel shaft (6) are mounted on the base (1); and arc-shaped concave-groove (12) are formed in the circumferential direction on both the upper sizing wheel (5) and the lower sizing wheel (7). Reinforcing bar obtains a reinforcing bar section of the consistent shape and size by pressing a vaulted groove on the upper sizing wheel and the lower sizing, which effectively prevents reinforcing bar from being twisted, and the subsequent shaping operation can be further omitted.
Description
Technical field the utility model relates to a kind of machine straightening device of stirrup bender band sizing mechanism.
Background technology is as same reinforcing bar of bending hoop raw material, and the diverse location diameter all exists ± difference of 0.2--± 0.5 millimeter.Reinforcing bar can produce and reverse in the bending hoop processing, and two broken ends that cause stirrup not in one plane do not need follow-up shaping, have not only increased processing cost, and because of being provided with of trimming increased the production floor space, and influenced production efficiency.
On the other hand, existing stirrup bender generally has roller straightening mechanism, and the straightening of being adopted up and down wheel is the flute profile wheel.Have the gap between the reinforcing bar of straightening race and the race about the process, reinforcing bar can produce equally and reverse.
Utility model content technical problem to be solved in the utility model is: a kind of sizing straightening device of steel bar hoop bending machine is provided, at first through sizing processing, obtained section consistent in shape and size, and then avoid reinforcing steel bar twisting before reinforcing bar is by straightening.The utility model also raises the stability that through ship further improves the reinforcing bar operation by improving.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of sizing straightening device of steel bar hoop bending machine, comprise the base that is fixed on the stirrup bender body, flute profile straightening wheel and adjustable contact roller are installed on base, it is characterized in that: also comprise being positioned at described flute profile straightening wheel and adjustable contact roller front end, the last sizing of mutual tangent installation is taken turns and following sizing is taken turns; Wherein, last sizing wheel is installed on the sizing wheel shaft by needle bearing; Following sizing wheel is installed in down on the sizing wheel shaft by needle bearing; The inner of last sizing wheel shaft and following sizing wheel shaft is installed on the base; All circumferentially offer the arc race on last sizing wheel and the following sizing wheel.
Also comprise the installing plate that be arranged in parallel with base, this installing plate is fixed on the base by connecting bolt; The outer end of last sizing wheel shaft and following sizing wheel shaft is installed on this installing plate; Last sizing wheel and following sizing wheel are between base and installing plate.
Wherein, the installing hole height of last sizing wheel is greater than the diameter of last sizing wheel shaft, and the adjustment bolt that is used to hold out against the sizing axle vertically is being installed respectively on base and the installing plate.
Arc race on last sizing wheel and the following sizing wheel is two of setting parallel to each other.
Adjustable contact roller is flat wheel.
Good effect of the present utility model is:
(1), reinforcing bar at first under the arc race extruding on last sizing wheel and the following sizing wheel by sizing mechanism, obtain reinforcing bar section consistent in shape and size, effectively avoided reinforcing steel bar twisting, and then can omit follow-up shaping and operate.
(2), will go up sizing wheel and following sizing wheel and pull down the back upset and reinstall for 180 °, another group arc race is on the reinforcing bar circuit, can realize that the sizing of different size reinforcing bar is processed, and has improved the machine service efficiency.
(3), adjustable contact roller is designed to flat wheel, reinforcing bar during through straightening mechanism with up and down between the straightening wheel for better 3 of stability contacts, further improved the stability that reinforcing bar moves.
Description of drawings Fig. 1 is a structural representation of the present utility model.For show internal structure, cutd open installing plate among this figure.
Fig. 2 is an A-A cross-sectional schematic of the present utility model.Compare with Fig. 1, increased installing plate among this figure.
Fig. 3 is the schematic side view of flute profile straightening wheel.
Fig. 4 is the schematic side view of adjustable contact roller.
The specific embodiment further describes the utility model below in conjunction with accompanying drawing and instantiation.
As shown in Figure 1, in this example, base 1 is fixed on the stirrup bender body by several fastening bolts 11.On base 1, two flute profile straightening wheels 10 are installed, above two flute profile straightening wheels 10, two adjustable contact rollers 9 are installed by axle and ball bearing by axle and ball bearing.Wherein, adjustable contact roller 9 is a flat wheel shown in Figure 3, and flute profile straightening wheel 10 has V-shape circumferential recess 14 shown in Figure 4.Bolt 8 is installed on base 1, can regulates the thrust size of adjustable contact roller 9 by it.Reinforcing bar through between adjustable contact roller 9 and the flute profile straightening wheel 10 time by straightening.
The installing plate 13 that be arranged in parallel with base 1 is fixed on the base 1 by connecting bolt 2; The inner of last sizing wheel shaft 4 and following sizing wheel shaft 6 all is fixedly mounted on the base 1, and the outer end of last sizing wheel shaft 4 and following sizing wheel shaft 6 all is fixedly mounted on this installing plate 13; Last sizing wheel 5 is installed on the sizing wheel shaft 4 by needle bearing, and following sizing wheel 7 is installed in down on the sizing wheel shaft 6 by needle bearing, last sizing take turns 5 and following sizing take turns 7 between base 1 and installing plate 13.
Circumferentially offer arc race 12 on last sizing wheel 5 and the following sizing wheel 7.Arc race 12 on last sizing wheel 5 and the following sizing wheel 7 is two of setting parallel to each other.Two arc wheel channel opening width that a sizing is taken turns are different, and two arc race sizes of corresponding (being the position correspondence) always up and down.Reinforcing bar through two arc races of up and down corresponding (being the position correspondence) after by sizing, to go up and overturn 180 ° after sizing wheel 5 and following sizing wheel 7 are pulled down, the interior outside is exchanged, and reinstalls, another group arc race is on the reinforcing bar circuit, can realize the sizing processing of different size reinforcing bar.
The installing hole of last sizing wheel 5 is a slotted eye, and the installing hole height is greater than the diameter of last sizing wheel shaft 4, and the adjustment bolt 3 that is used to hold out against sizing axle 4 vertically is being installed respectively on base 1 and the installing plate 13.Adjust bolt 3 lower ends and hold out against sizing axle 4 for these two during work, need dismounting to go up sizing and take turns and unclamped these two adjustment bolts 3 at 5 o'clock and get final product latter location.The effect of this adjustment bolt 3 also has following two aspects, and first, can be by regulating the height of sizing wheel 5 in its apical position adjustment, and then adjust the sizing size; The second, can become flexible this easily and adjust bolt 3, be beneficial to successfully reinforcing bar be penetrated in the sizing race.
