Definitions

• the present invention relates to a shaping device, particularly for shaping substantially elongated elements. More specifically, the invention concerns a shaping device of the above kind, studied and realised particularly for working the surface of elements, preferably comprised of wood, having different dimensions, under maximum safety and precision conditions.
• a shaping device of the above kind, studied and realised particularly for working the surface of elements, preferably comprised of wood, having different dimensions, under maximum safety and precision conditions.
• the specification will be particularly referred to the working of wood, but it is well evident that the device according to the invention can be used also for working different materials, all these different uses being included within the scope of the present patent application.
• at present machines do not exist which are specifically created for shaping small wood pieces.
• Object of the present invention is that of suggesting a device that can guarantee very precise and safe wood shaping operations. Another object of the present invention is that of suggesting a device that can be realised by low manufacturing costs. A further object of the present invention is that of allowing the realisation a device that can be used in a flexible way, being easily adaptable to the dimensions of wood parts to be worked on. It is therefore specific object of the present invention a shaping device, preferably for shaping substantially elongated elements, characterised in that it comprises at least a shaping tool, a support and containment structure, above which said shaping tool is placed, guide means for said substantially elongated elements, said guide means being placed in said support and containment structure and being provided with means for adjusting the dimensions in function of the working element.
• said structure can comprise a lower base and an upper base, spaced by vertical supports, said upper base providing a hole for the coupling of said shaping tool.
• said adjustment means for said guide means can comprise horizontal guide means, vertical guide means, horizontal adjustment means and vertical adjustment means.
• said horizontal adjustment means can comprise at least two crosspiece elements, faced each other, said crosspiece elements being slidable along guides and coupled to said lower base, and preferably can provide a bevelling in correspondence of two upper corners of the facing surfaces.
• said horizontal adjustment means can comprise at least a worm screw, that can be actuated by a wheel, said worm screw can have half of the threading left-handed and half of the threading right-handed and be coupled with corresponding threaded portions provided on said facing crosspiece elements, in such a way that they can be moved away or approached by the adjustment.
• said horizontal guide means comprise two turrets, each turret being fixed to one of said crosspiece elements.
• each one of said turrets can comprise a notch, on the surface faced toward the other turret, said notch being realised above a tongue or projection, each one of said tongues having a substantially rectangular shape and being suitable to create the lateral edge of a guide channel.
• said horizontal guide means can comprise two substantially rectangular trapezoidal shaped elements, provided under said tongues or projections.
• said vertical guide means can comprise a first triangular element, suitable to create, with its base, the lower edge of said channel guide, said first triangular element being provided above said substantially rectangular trapezoidal elements.
• said vertical adjustment means can comprise an upper gib, a lower gib, each one of said gib elements can have a isosceles triangle section, said upper gib can be engaged in said notches of said turret, said lower gib can be placed on said bevellings of said crosspieces, said vertical adjustment means can provide means for bringing back said upper gib toward said upper base.
• said return means can be comprised of a pre-stressed spring.
• said vertical adjustment means can comprise second return means, preferably a second pre- stressed spring, provided between said first isosceles triangle element and said lower gib, third return means, preferably a third pre-stressed spring provided between said lower gib and said lower base, and fourth return means, preferably two pre-stressed springs, particularly obliquely placed between said crosspiece means and said isosceles trapezoidal elements, all the above in such a way that, as a consequence of the moving away of said crosspiece elements, said turrets, moving away allow to said upper gib to approach to said upper base by the action of said first spring, said first isosceles triangular element lowering by the action of said second spring, said lower gib lowering by the action of said third spring, said isosceles trapezoid elements moving away by the action of said two springs provided according to a oblique orientation.
• second return means preferably a second pre- stressed spring, provided between said first isosceles triangle element and said lower gib
• said structure can comprise coupling means for said shaping tool.
• said shaping tool can be a milling machine.
• Figure 1 shows a front perspective view of the wood shaping device
• Figure 2 shows a lateral perspective view of the shaping device of figure 1
• Figure 3 is a first view of the particular of the assembly of adjustment elements of the shaping device according to figure 1
• Figure 4 is a second view of the adjustment element assembly of figure 3, for the shaping device of figure 1 , suitable for a worked piece
• Figure 5 shows some possible shaping that can be realised by the shaping device of figure 1 .
• device 1 comprises a horizontal basis 2, for example having a substantially square shape and two feet 21 on the corners of said horizontal basis 2, it is possible observing vertical supports 22, on which the upper base 23 is placed.
• Said upper basis 23 provides a substantially central hole 231 .
• Said hole 231 is necessary to apply a working tool 3 (in figures 1 and 2 two different kind of tools are shown, particularly an electro milling machine).
• Said electro milling machine 3 can be any kind already available on the market. More particularly, the one shown in figure 2 provides a milling cutting tip 31 , a support structure 32 and coupling means 33, coupled with the upper base 23. Furthermore, handles 34 are provided.
• An assembly 4 is placed between the lower base 2 and the upper base 23, comprising adjustment elements for the shaping device 1 that will be described in greater detail in the following with reference to figures 3 and 4.
• Said assembly 4 provides a wheel 41 operating on a worm screw 42, and having a half left-handed threading and a half right- handed threading.
• Said worm screw 41 acts on two crosspiece elements 44, slidable along guides 421 , provided on said lower base 2, moving them away and approaching said elements 44, on the basis of the work piece.
• Two turrets 43 are provided above said crosspiece elements
• Said turrets 43 provide lateral tongues 432, on their surfaces faced inwardly, allowing to create a profile suitable to the housing, under a triangular element 45 and two trapezoidal elements 46, provided symmetrically and above an upper gib 491 .
• Said trapezoidal elements 46 are connected to said crosspiece elements 44 by oblique spring 47.
• Said triangular element 45, provided above said trapezoidal elements 46 is connected to a lower gib 49 by a vertical spring 48.
• Said gibs 49 and 491 are respectively coupled with the lower base 2 and with the upper base 23 by vertical springs 481 and 482.
• said gib 491 is provided with a hole, not shown, corresponding with said hole 231 provided on said upper base 23.
• a traverse element 232 is present, fixed to the upper base 23, to fix the distance of said upper base 23 from the turrets 43.
