Description
Technical field
The utility model belongs to rotary-cut machinery field, more particularly to a kind of cam control constant pressure peeler.
Background technology
At present to improve the uniformity of no-jamming timber rotary cut rotary cut venner, in addition to Numeric Control Technology is widely adopted, improve
The pressure condition of nose bar roller is also most important, and it is opposite with nose bar roller that automatic adjustment knife crack between a door and its frame gap namely automatically adjusts peeling knife
Position and then change nose bar roller to the pressure of timber, in practice it has proved that effectively, progressively promoted in recent years, but there is also some not
Foot.Most equipment manufacturers replace curve pair rail with straight line pair rail, and equalitarianism is not careful accurate enough, and effect is had a greatly reduced quality, separately
The amplification of outer knife seam can bring the decline of veneer smoothness.Automatic tool setting mechanism is a kind of method and measure, and the purpose is to adjust
For nose bar roller to the pressure of timber, this is the inherent technological requirement of timber rotary-cut.A set of mechanism can be designed, is basically unchanged in knife seam
In the case of achieve the purpose that adjust nose bar roller to the pressure of timber, it is smooth to take into account veneer while the veneer uniformity is ensured
Degree is to improve the important subject that peeler performance need to capture.
The content of the invention
The purpose of the utility model is to overcome insufficient in the prior art, it is long to provide a kind of service life, high precision machining
Cam controls constant pressure peeler.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of cam controls constant pressure peeler, including nose bar roll assembly, nose bar roll assembly pedestal, nose bar roll assembly pedestal
Shaft, compression relief cam, camshaft, Cam bearing pedestal, idler wheel, sprocket wheel, tensioner sprocket wheel, chain, knife platform component, peeling knife, double roller
Component, rack；The nose bar roll assembly is packed on nose bar roll assembly pedestal, and nose bar roll assembly is fixed on the knife platform component
Base shaft, Cam bearing pedestal, tensioner sprocket wheel, the nose bar roll assembly pedestal kink, can on nose bar roll assembly base shaft
Small-scale swing is done around nose bar roll assembly base shaft, is provided with what is contacted with cam holding on the nose bar roll assembly pedestal
Idler wheel, the double roller component are fixed in rack, and the knife platform component does the reciprocal into withdrawing of horizontal direction along rack upper rail
Movement, the sprocket wheel, tensioner sprocket wheel are done with knife platform component back and forth into withdrawing, and the chain both ends being engaged with are each attached to rack
On, with the sprocket wheel that cam coaxial is fixedly mounted with rotation fortune is done around cam center when Sui Daotai components do and back and forth move along a straight line into withdrawing
Dynamic, the rotation of cam by keeping the idler wheel of contact that nose bar roll assembly pedestal is driven to do small-scale swing therewith, so as to change
The relative position of nose bar roller and peeling knife, and then in time control pressure of the nose bar roller to timber.
Preferably, the surface of the nose bar roller and double roller is equipped with netted lines, in processing, it is made to produce wood surface
The frictional force of raw bigger, prevents timber from skidding in rotation process, influences machining accuracy.
Advantageous effect is shown the utility model compared with prior art：
The cam of rotary cutting machine pressure-bar roller constant pressure control is based on timber Archimedes's appearance curve in itself and unique
Correct squeezing rate calculation formula（Professional standard remains to be discussed with the formula in specification）, kept constant with the variation of timber diameter
Squeezing rate do it is accurate calculate design, the making of part is process through techniques such as spark cutting, quenching, grindings, and existing
Straight line pair rail automatic knife gap adjusting mechanism, averagely firmly size diameter is difficult to take into account, the raising for rotary-cut technology, existing straight
The problem of what line pair rail automatic knife gap adjusting mechanism solved is from scratch, it is qualitative correct but quantitative rough, and cam control constant pressure
Power peeler it is qualitative correct, quantitative accurate, better than existing straight line pair rail automatic knife gap adjusting mechanism；
The oscillation center i.e. nose bar roll assembly base shaft of nose bar roller are in the back upper place of position of tool tip, and cam controls
Nose bar roller track and knife spine contour line substantially in parastate, therefore cam is adjusting the rotary-cut process of nose bar roller pressure
In maintain knife seam and be basically unchanged, after batch production is launched, user's long-time production testing, the veneer uniformity and smooth
Degree is superior to still belong to progressive automatic knife gap adjusting mechanism at present；
Cam directly drives idler wheel, and the pendulum radius of idler wheel is more than the pendulum radius of nose bar roller, and cam stress is more directly driven
Dynamic pressure ruler roller is moved horizontally will reduce from knife gap adjusting, and cam is more reliable durable, equally be to be by the transform linear motion of knife platform
The rotary motion of cam, sprocket wheel link chain mechanism are more preferable compared with rack and pinion mechanism processability of product structure, more simple and practical.
