A New Four Side Moulder For European-style Wood Windows

With European-style wood window gradually entering China market, the demandis gradually rising, the market’s prospect is very good. The demand for woodworkingmachinery and equipment to produce top grade European-style wood window isgradually warming up. Now the China factory mainly use two kinds of equipments toproduce such windows: one is imported CNC window’s processing center,in thismachine can produce out main components of the window. The advantage is high gradeof automation,high precision. The disadvantage is the machine’s price is very high, themaintenance cost is also high. Another processing machine is general woodworkingmachinery, the window frames longitudinal processing use the four side moulder, thewindow frames two sides’ horizontal processing use vertical milling machine.Theadvantage is machine’s price is low,the maintenance cost is also low. The disadvantageis when using the four side moulder to make large amount longitudinal processing,itneed several times to finish, and need to work again to finish the rough allowance, theworking efficiency is low. At the same time, the workpiece and feeding roller’stouching area is small, so the feeding strengthe sometimes is weak, the workpiece’sfeeding is stopped or slow. So the substandard and defective products’ quantity will rise.The new four side moulder have the ability to finish the longitudinal processing in onetime, and with additional attachments can do the horizontal processing on two sides ofwindow,Now the domestic market don’t have this kind of four side moulder.On thebackground of gradually demanding of high grade European-style windows,this kind ofnew four side moulder will have broad market prospect.After analyzing the advantage and disadvantage of the existing four sidemoulder,depend on the four side moulder’s processing principle, combined with theprocess of European-style solid wood windows to design the four side moulder whichfit to produce such windows.The four side moulder’s design include machine body,front working table and guider board,feeding mechanism,cutting mechanism,pneumaticclamping mechanism, the elevating mechanism for clamping device,and the electricalcontrol part’s design. The lower horizontal main spindle’s design of the pre-cuttingapparatus cutting the workpiece’s processing reference to depend on a small guide plateguiding, so the workpiece processing don’t need the step of rough work. Left and rightvertical spindles’ design can be equipped with quick-change hydraulic clamping toolchanger, save the changing knives time,because of different window frame shape, this can save costs compared with the wood windows’ CNC vertical machining main spindle.Through experiments and calculations, the choice of the left and right vertical spindlecan have much stronger cutting power compared with the general four side moulder,then new design will more fit the processing of wood window processing. The secondupper horizontal main spindle add saw blade and chopper, to finish the glass beadprocessing at the same time of window frame processing. The left vertical spindle’sdust hood and clamping device can be quickly replaced, the left vertical spindle can bereduced to below the level of working surface, on the basis of adding accessories,themachine can do horizontal processing of the window frame side. Feeding mechanismselects the frequency inverter and frequency conversion motor to control feeding speed,the electrical part include overall electrical control and component selection and thefigures show’s design.
