Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As depicted in figs. 1 and 2, this comprises frame for location adjusting device of reinforcing steel bar truss forming machine and to be installed in frame and one group of positioning track 10 for placing waveform reinforcing bar, frame is provided with and positioning track 10 one group of positioning component one to one, positioning component comprises the level pressure pin unit be connected with frame and the multiple dynamic pressure pin unit be flexibly connected with frame, each dynamic pressure pin unit can simultaneously near or away from level pressure pin unit, each presser feet unit is all for pressing solidly waveform reinforcing bar at corresponding positioning track 10.
On reinforcing steel bar truss forming machine, reinforcing bar first carries out bending through wave forming device, then welding sequence is entered into, in order to meet the demand of steel bar girder different size structure, waveform spacing and the size waveforms of the waveform reinforcing bar produced in wave forming device all can change with the need, and detent mechanism positions to waveform reinforcing bar according to waveform spacing, need correspondingly to change location spacing.
For this reason, the present invention devises a kind of location adjusting device for reinforcing steel bar truss forming machine, while meeting strong fix can according on operation size adjustment location spacing of the waveform spacing of waveform reinforcing bar of producing, to adapt to the location requirement of the waveform reinforcing bar of different size structure.
Waveform reinforcing bar after bending and molding moves along positioning track 10 when entering welding sequence, then waveform reinforcing bar presses solidly on positioning track 10 by each presser feet unit, positioning track 10 and the work of each presser feet unit matching make waveform reinforcing bar positioning stablity, are convenient to carry out welding job.
Wherein, each dynamic pressure pin unit can simultaneously near or away from level pressure pin unit, namely can correspondingly reduce according to the waveform spacing size of waveform reinforcing bar or increase and locate spacing.
Preferably, level pressure pin unit comprises rack-mounted level pressure pin 23 and for driving the first oil cylinder 22 of level pressure pin 23, each dynamic pressure pin unit includes mount pad 31, mount pad 31 is provided with dynamic pressure pin 33 and for driving the second oil cylinder 32 of corresponding dynamic pressure pin 33, level pressure pin 23, each dynamic pressure pin 33 equidistantly distribute along the axial direction of corresponding positioning track 10 successively, and each mount pad 31 all can related correspondence dynamic pressure pin 33 simultaneously near or away from level pressure pin 23.
Preferably, positioning track 10 axially offers locating slot 11, each oil cylinder can drive corresponding presser feet to be pressed solidly in locating slot 11 by waveform reinforcing bar.
Particularly, what directly contact with waveform reinforcing bar is each presser feet, each presser feet presses solidly stable for waveform reinforcing bar under the effect of the oil cylinder of correspondence, and the position that each presser feet contacts with waveform reinforcing bar is the wave trough position of waveform reinforcing bar, therefore, the distance (location spacing) between two adjacent presser feets and the distance (waveform spacing) between corresponding adjacent two troughs consistent.
Due to, each the waveform configuration shape in same waveform reinforcing bar is consistent, and namely each waveform spacing is equal, so just needs each location spacing equal.Therefore level pressure pin 23, each dynamic pressure pin 33 are equidistantly distributed along the axial direction of positioning track 10 successively, the direction that alternatively level pressure pin 23, each dynamic pressure pin 33 extend along waveform reinforcing bar successively equidistantly distributes, and so just can ensure that each location spacing is equal.
Each mount pad 31 all can related correspondence dynamic pressure pin 33 simultaneously near or away from level pressure pin 23, such setting is then the location requirement of the waveform reinforcing bar in order to meet various different structure size, while waveform spacing changes, location spacing also needs corresponding change, each presser feet is made to press solidly wave trough position at waveform reinforcing bar, thus guarantee that location is firm, be convenient to carry out welding job.
The setting of locating slot 11 is the positions in order to locate trough, avoids waveform reinforcing bar to offset, and ensures that welding sequence steadily carries out.
In the present embodiment, middle part and the frame of preferred level pressure pin 23 are articulated and connected, and level pressure pin 23 one end is connected with the first oil cylinder 22, and the other end can be pressed in locating slot 11; The middle part of each dynamic pressure pin 33 is articulated and connected with corresponding mount pad 31 respectively, and one end of each dynamic pressure pin 33 is all connected with the second corresponding oil cylinder 32, and the other end all can be pressed in locating slot 11.
When positioning, waveform reinforcing bar presses solidly in locating slot 11 by presser feet corresponding to each hydraulic oil cylinder driving, and after welding job completes, initial position got back to by each oil cylinder, and corresponding presser feet then can depart from waveform reinforcing bar.
Each oil cylinder vertically arranges, each presser feet can be thought horizontally disposed, when continual positioning work, when oil cylinder reciprocating works, corresponding presser feet rotates around it self pin joint, so, can reduce the impulse stroke of oil cylinder and presser feet to a certain extent, structure is compacter, reduces taking of locus.
What deserves to be explained is, level pressure pin 23 is positioned at one end that waveform reinforcing bar enters location adjusting device at the beginning, and when reinforcing bar carries out bending work, level pressure pin 23 carries out pressuring action for reinforcing bar, to make reinforcing bar not offset at Forging Process, keeps stable state.Level pressure pin 23 is also for waveform reinforcing bar carries out compression location when welding simultaneously, and such structural design makes overall structure compacter, saves working space, is also convenient to the carrying out of whole production work.
As shown in Figures 2 to 4, further preferably, frame is provided with and positioning track 10 one group of adjusting screw(rod) 40 one to one, adjusting screw(rod) 40 runs through by each mount pad 31 and each mount pad 31 is all threaded with adjusting screw(rod) 40, and the line number of adjusting screw(rod) 40 and the screw thread of each mount pad 31 junction is that multiple increases along dynamic pressure pin 33 direction of level pressure pin 23 to outermost.
In order to make each dynamic pressure pin 33 simultaneously near or away from level pressure pin 23, adopt an adjusting screw(rod) 40 to run through structural design by each mount pad 31.
When carrying out adjustment work, the dynamic pressure pin 33 adjacent with level pressure pin 23 moves certain distance towards level pressure pin 23 under the effect of adjusting screw(rod) 40, if adjusting screw(rod) 40 is equal everywhere with the line number of the screw thread of each mount pad 31 junction, pitch is equaled and line number is long-pending due to helical pitch, so when pitch is identical, helical pitch is also identical, and the distance of now all dynamic pressure pin 33 movements is all equal, and the distance between adjacent dynamic pressure pin 33 would not change.
But due in initial, each presser feet is equidistantly distribution, and the distance between namely adjacent presser feet is all equal, and the distance now between level pressure pin 23 and adjacent dynamic pressure pin 33 has decreased, but distance between adjacent dynamic pressure pin 33 is constant.So, be not just equidistantly between each presser feet, that is locating spacing is not that each and every one is equal, each presser feet just cannot with the trough one_to_one corresponding of corresponding waveform reinforcing bar, cannot work be positioned.
In order to address this problem, be that multiple increases by the line number of adjusting screw(rod) 40 and the screw thread of each mount pad 31 junction along dynamic pressure pin 33 direction of level pressure pin 23 to outermost, when pitch is identical, the helical pitch of adjusting screw(rod) 40 and each mount pad 31 junction is that multiple increases along dynamic pressure pin 33 direction of level pressure pin 23 to outermost.
Suppose that the mount pad 31 at dynamic pressure pin 33 place adjacent with level pressure pin 23 is a with the helical pitch of adjusting screw(rod) 40 junction, the mount pad 31 at so next dynamic pressure pin 33 place is 2a with the helical pitch of adjusting screw(rod) 40 junction, so down, helical pitch is followed successively by 3a, 4a, 5a etc.
Now adjusting screw(rod) 40 acts on, the dynamic pressure pin 33 adjacent with level pressure pin 23 is the distance of x towards level pressure pin 23 movable length, next dynamic pressure pin 33 moves the distance of 2x towards level pressure pin 23, so down, dynamic pressure pin 33 afterwards moves the distance of 3x, 4x, 5x successively towards level pressure pin 23.And all correspondingly to reduce length between adjacent dynamic pressure pin 33 be the distance of x, so, be still equidistantly distribution between each presser feet, the location to waveform reinforcing bar can not be affected.
In like manner, when adjusting screw(rod) 40 with each dynamic pressure pin 33 away from level pressure pin 23 time, be still equidistantly distribution between each presser feet.
As shown in Figure 1, Figure 2 and Figure 4, preferably, the quantity of positioning track 10 is two and the quantity of adjusting screw(rod) 40 is also two, frame is also provided with the motor 50 for driving two adjusting screw(rod)s 40, motor 50 has output shaft and on output shaft, is arranged with driving gear 61, and each adjusting screw(rod) 40 is all arranged with the driven gear 62 be connected with a joggle with driving gear 61 near motor 50 one end.
In the present embodiment, the quantity of positioning track 10 is preferably two, and two waveform reinforcing bars can be made symmetrical and weld on cross section, the good and steel bar girder anatomic shape formed of symmetry.Correspondingly, the quantity of adjusting screw(rod) 40 and positioning component is also respectively two.
In order to make whole location adjusting device structure more compact, in the present embodiment, in same positioning component, each presser feet is equidistantly distributed in positioning track 10 side along same straight line, and wherein two positioning components divide the opposing side being listed in two positioning tracks 10, facilitate the installation of related components.
Because two waveform reinforcing bars carry out welding job simultaneously, the uniformity needing guarantee two adjusting screw(rod) 40 to regulate, therefore have employed the structure that driving gear 61 is connected with a joggle with two driven gears 62 simultaneously, regulates two adjusting screw(rod)s 40 by motor 50 simultaneously.The setting of motor 50 makes adjustment more convenient, also can avoid producing error because regulating manually, and in addition, two driven gears 62 are connected with a joggle with driving gear 61 respectively, stable drive, regulate more stable.
In addition, between motor 50 and driving gear 61, a reductor can also be installed, make the transmission between motor 50 and driving gear 61 more steady, ensure the stability regulated further.
This is used for the location adjusting device of reinforcing steel bar truss forming machine in an initial condition, and waveform reinforcing bar enters positioning track 10, and waveform reinforcing bar presses solidly in locating slot 11 by each presser feet under the effect of the oil cylinder of correspondence, then just can carry out welding job.When the waveform spacing of waveform reinforcing bar changes, two adjusting screw(rod)s 40 can be driven to regulate accordingly the distance between adjacent presser feet by motor 50, thus corresponding waveform reinforcing bar is positioned.This device is easy to operate, can regulate according to the waveform reinforcing bar of different wave spacing to location spacing, applied widely.
