Description

Continuously operating press
Technical field
The utility model is related to a kind of continuously operating press.
Background technology
Continuously operating press can be generally used when large scale industry produces timber flitch.In these forcing presses, such as Described in the C2 of DE 39 13 991 like that, press power is delivered on pressing plate and heating plate and subsequent by hydraulic regulation component It is delivered on binder via steel band, these steel bands supportedly turn round arrangement via rolling element blanket (rolling bar).For in hydraulic regulation The power stream of the power produced in component is transmitted and supported basically by hydropress frame.The further remodeling of this forcing press is visible The C2 of the DE 40 17 791 and B4 of DE 43 40 982.
It is common for all these prior arts, continuously operating press is divided into some along compacting circuit Region.It is initially feed zone, the feed zone is hereinafter ignored, because this is related to the particular configuration of the first compressional zone (as known to the C2 of DE 43 01 594), and the wedge-shaped compacting machine of so-called charging also is known as the art.It is this Compacting machine receives the pressure pad from feeding device and is compacted the pressure pad according to the main compacting profile for mixing up in advance.If Compacting gap substantially achieves the thickness of final products, and material is located at high-pressure area (HD), intermediate pressure section in subsequent material arrival And area of low pressure (ND) (MD).Substantially heated and plastified in the first two region.These regions are due to the height needed for it Press power and there is substantially solid hydropress frame.Area of low pressure (ND) generally gives the plate of material time to complete solidification.
The basic distinction in these three regions is the different configuration of hydropress frame, these different configurations for it is different most Big power is designed, with cost-effective in production.The difference slave unit technical standpoint in these regions is seen and is:Framework structure The different materials intensity made, be the number and size of the hydraulic cylinder that each row (transverse to production mode reform) are used, be to make Pressure plare spacing of supporting etc. needed for hydropress frame is carried out.In addition it is known and for technical staff, herein for machinery It is distinctive for engineer to be, for the same area use identical part as far as possible with identical set and symmetrically Arrange these parts.
Therefore, it is known to arrange various bare bones along continuously operating press for different regions (HD, MD, ND) Frame, wherein, in each area using identical hydropress frame, and hydropress frame and its form of implementation Jin Liangge areas Just there is difference transition part office between domain.
Due to the possibility of the FEM that the cost rising of metal and steel construction and the constructing technology supported with modern PC are combined, The amount of spent metal is always reduced more and more.This can cause current forcing press no longer with required rigidity. But purpose is still to compensate deformation and life due to the forcing press that temperature is caused by the bending of forcing press plate and regulation simultaneously Produce final products reported as precisely as possible.
But for producing optimal final products with dimensional stability reported as precisely as possible disadvantageously, directly by The forcing press plate of hydraulic cylinder loading is in its Longitudinal extending and extends laterally with inexactness on direction, because adding in no pressure Area inner pressure machine plate meeting " breathing " of load and along sweep bend.Thus, produced at plate of material to be produced poor Thickness tolerance.
