Background technology
1. discontinuous PU main frames are also known as laminating machine, during work, two boards are carried out live injection, foaming, solidification it is same
When, other two boards are loaded and unloaded, therefore also referred to as 2 plus 2 laminating machinees.The machine feature be equipment volume than larger, quality weight, so
During discontinuous PU main frames matched moulds and molding, it is desirable to which guiding accuracy when upper mould is moved is high, to ensure die joint
Positional precision.
2. at present, guiding mechanism is mainly by guide pillar guide pin bushing, Timing Belt, leading screw, rack-and-pinion to realize.Its feature
It is：
(1) the characteristics of guide pillars, guide pin bushing：Guide pillar, guide pin bushing are the most frequently used guiders in design of stamping die, are continuous
The strength member of upper and lower mould, can guarantee that blade clearance, harmful effect of the pressing equipment to mould when reducing punching, and can bear
The side force produced during punching.
(2) the characteristics of Timing Belts：Bearing capacity will widen belt when larger, drive length can not be too big, otherwise needs to examine
Consider larger elastic deformation and vibrations, transmission distance is not particularly suitable for being accurately positioned continuity motion control greatly.
(3) the characteristics of leading screws：Common trapezoidal screw can be with self-locking, and this is great advantage, but transmission efficiency is low, than
Guide pillar guide pin bushing, both Timing Belts efficiency it is much lower, tell round transmission so inadaptable.Have the disadvantage to have put into practice long drive gap
Greatly, backhaul precision.
The content of the invention
The technical problems to be solved by the invention are：A kind of discontinuous PU main frames template lifting synchronization steering mechanism is provided,
Solve the problems, such as PU main frames template lifting actuator low precision, poor synchronization in the prior art.
The present invention uses following technical scheme to solve above-mentioned technical problem：
A kind of discontinuous PU main frames template lifting synchronization steering mechanism, including falsework, the downward vertical of falsework
Many one sides are set with serrate tooth bar, horizontal and vertical power transmission shaft is set on tooth bar, the both sides per toothed rack are relative
Set a pair of bearing, fixed gear and guide wheel between two bearing blocks, wherein, the engagement of wheel and rack, guide wheel with
Gear is relatively arranged on the both sides of tooth bar.
The falsework is rectangle, and tooth bar is symmetricly set on the side long of the falsework, and two falseworks are long
While sharing a longitudinal drive shaft respectively with two tooth bars of one end, the tooth bar of each side center section long of falsework is total to
With a horizontal power transmission shaft.
The flank of tooth of falsework side two ends tooth bar long towards end outside.
The center section on each falsework side long respectively includes two toothed racks.
Connector is set between falsework and tooth bar.
The connector includes the clamping thing being fixed on falsework side long, and one end of tooth bar is arranged at the folder of clamping thing
Portion is held, and is fixed by steady pin.
The side of tooth bar is engaged with gear, and opposite side coordinates with guide wheel.
Compared with prior art, the invention has the advantages that：
1st, rack-and-pinion, bearing capacity is big, high transmission accuracy, up to 0.1 millimeter, can indefinite length docking continuity, transmission speed
Degree can be very high, up to 2 metre per second (m/s)s.
2nd, transmission power is big, efficiency high.
3rd, long lifespan, stable working, reliability is high.
4th, constant gearratio is can guarantee that, the motion of the between centers of any angle two can be transmitted.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model lifting synchronization steering mechanism.
Wherein, being designated in figure：1- gears；2- tooth bars；3- guide wheels；4- transverse direction power transmission shafts；5- bearing blocks；6- is longitudinally passed
Moving axis；7- falseworks.
Specific embodiment
Structure of the present utility model and the course of work are described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of discontinuous PU main frames template lifting synchronization steering mechanism, including falsework 7, falsework
7 downward vertical sets 8 toothed racks 2, and horizontal and vertical power transmission shaft is set on tooth bar 2, and the both sides per toothed rack 2 are relative to be set
A pair of bearing 5 is put, fixed gear 1 and guide wheel 3 between two bearing blocks 5, wherein, the engagement of gear 1 and tooth bar 2 is led
Wheel 3 is relatively arranged on the both sides of tooth bar 2 with gear 1.
The falsework 7 is rectangle, and tooth bar 2 is symmetricly set on the side long of the falsework 7, two falseworks
7 sides long share a longitudinal drive shaft 6 respectively with two tooth bars 2 of one end, each the side center section long of falsework 7
Tooth bar shares a horizontal power transmission shaft 4.
The flank of tooth of the side two ends tooth bar 2 long of falsework 7 towards end outside.
The center section on each side long of falsework 7 respectively includes two toothed racks.
Connector is set between falsework and tooth bar.
The connector includes the clamping thing being fixed on falsework side long, and one end of tooth bar is arranged at the folder of clamping thing
Portion is held, and is fixed by steady pin.
Tooth bar side is engaged with gear, to realize the synchronous effect of mechanism；And opposite side coordinates with guide wheel, to realize mechanism
Guide effect.Tooth bar, gear and guide wheel three are achieved that the synchronization of mechanism and the double action of guiding.
The embodiment uses steady pin, can also be fixed by other means, such as screw etc., as long as can be real
The fixed function of existing effect.
The operation principle of the lifting synchronization steering mechanism of the present embodiment is as follows：
Pinion and rack, is exactly the mechanism for completing linear motion and rotating mutually conversion.Its each several part relation and function
It is as follows：
Rack pinion is the linear reciprocating motion that the gyration of gear is changed into tooth bar, or by the reciprocal of tooth bar
Linear motion is changed into the gyration of gear.
Lifting synchronization steering mechanism of the present utility model is the revolution fortune that the linear reciprocating motion of tooth bar is changed into gear
It is dynamic, by gear and the engaged transmission of tooth bar, it is ensured that synchronization during falsework lifting process.In addition, passing through directive wheel and tooth
The cooperation transmission of bar, it is ensured that the positioning and guiding effect of falsework lifting.
If the processing installation accuracy of the equipment is poor, drive noise can be caused big, big problem of wearing and tearing, it is therefore desirable to pacify
To ensure its precision during dress.
The typical use of the device：Big space of a whole page steel plate.
