Definitions

the present invention relates to a die-holder/tray assembly for machines used for the die-forming of materials such as steel and the like, comprising means for constraining the relative rotation/rotary translation of the tray with respect to the said die-holder.
Said dies are normally housed inside support trays which are in turn inserted in the die-holders which consist of an apparatus formed by two parts - i.e. an upper part, integral with the press ram and movable therewith and a lower part fixed to the bottom of the press - which are joined together by suitable guiding and centring devices.
fixing of the tray is envisaged by means of keys projecting from the die-holders and designed to be inserted in corresponding seats of the tray so as to prevent the movements thereof on the bottom surface.
Locking in a perpendicular (vertical) direction with respect to the said bottom surface is performed by means of wedges or similar inclined surfaces.
the technical problem which is posed is that of providing die-holder/tray assemblies for the hot-pressing of steel or other material which are designed to prevent both the relative movements of the die-holders and the relative rotational/rotary translatory movement of the tray with respect to its die-holder.
the tray should also be able to be inserted into the associated die-holder by means of a translational movement while resting on the surface of the lower die-holder or on corresponding guides in the case of the upper die-holder.
a die-holder/tray assembly for machines used for the die-forming of materials such as steel and the like, comprising first means for the relative positioning and locking of the tray with respect to the die-holder and second means for constraining the rotation/rotary translation of the tray with respect to the said die-holder.
the die-holder device 10 consists of an upper die-holder 11 and a lower die-holder 12 which are connected together by columns 3 for guiding the relative translatory movement in the vertical direction.
a longitudinal direction X-X, a transverse direction Y-Y and a vertical direction Z-Z are indicated.
each bottom surface 12a of the associated die-holder element 12 has a first seat 13 arranged in the vicinity of the closed rear side 12b of the said die-holder 12.
Said seat 13 is designed to contain partially an insert 20 - in the example with a parallelepiped shape - which once inserted in the seat 13 will project partially in the vertical direction from the surface 12a (Fig. 4).
said insert is formed by a parallelepiped which is totally contained in the seat 13 and by a projection protruding vertically from said parallelepiped and therefore from the base of the die-holder.
Each bottom surface 12a is also provided with a second seat 16 arranged on the open front side of the die-holder and in turn open towards said front side.
Said seat is designed to house a second insert 30 (Fig. 3) which is in turn provided with a cavity 31 open towards the said front side of the die.
the tray 40 to which the die (known per se and therefore not shown) is applied has, in the bottom surface 41a of the base 41, a first seat 43 which is open towards the rear side 12b of the die-holder and has dimensions corresponding to those of the projection 13 emerging from the bottom surface 12a of the die-holder 12.
the front side of the bottom surface 41a of the said base 41 of the tray 40 is also provided with a projection 42 extending towards the outside in the vertical direction and having a shape and dimensions such as to mate precisely with the second front seat 31 of the bottom surface of the die-holder.
the engagement between said front projection 42 of the tray 40 and second seat 31 of the base 12a is designed to prevent rotation of the tray 40 and consequently the die with respect to the associated die-holder 12.
the arrangement of the said seats in the tray and the die-holder which are open on the rear side and front side of the die-holder respectively, allows insertion of the tray into the said die-holder by means of a translatory movement of the former which remains resting on the latter, avoiding the need for complex equipment for gripping, transporting and releasing the tray into its die-holder.
the tray is locked in the longitudinal direction X-X and vertical direction Z-Z by means of wedge elements 50 with a double inclination which project from corresponding seats 50a formed in the sides of the die-holder and upon operation of respective means such as oil-hydraulic cylinders or the like, not illustrated.
the means for locking rotation/rotary translation of the tray 40 with respect to the die-holder 12 may also be provided with means for adjusting the position of the tray in the transverse direction Y-Y.
the male rear block 220 and the female front block 230 have, passing through them in the longitudinal direction, respective holes 222,232 with a female thread; said holes 222,232, once the blocks have been inserted into their respective seat 113,116, are arranged coaxially with further through-holes 18 formed in the die-holder 12.
a threaded bar 150 which is arranged inclined with respect to the longitudinal axis X-X and can be manoeuvred on the front side of the die-holder and which is designed to engaged with the respective female threads of the two said inserts 220,230 so that operation of the screw in one direction or the other causes displacement, simultaneously and in the same manner, of the two said inserts either towards the rear or towards the front of the die-holder.
both the rear seat 113 and front seat 116 of the die-holder 12 and the associated blocks 220,230 have sides which are parallel, but inclined with respect to the longitudinal axis of symmetry of the die-holder; on the other hand the associated projection 220b and seat 231 of each block are parallel to said axis of symmetry, since they have to allow engagement with the corresponding seat and projection on the bottom side of the tray.
the tray 40 may still be inserted into the die-holder by means of a translatory movement while resting on the base of the die-holder and subsequent operation of the threaded bar 150 causes a displacement, in the longitudinal direction, of the elements 220,230 and, consequently, a displacement of the tray 40 in the transverse direction in a sense (Fig. 7a,7b) depending on the sense of rotation of the bar 150, this movement in the transverse direction allowing precise adjustment of the position of the tray.
the configuration of the adjustment and locking devices described above is moreover particularly strong since it is achieved by inserting the anti-rotation means inside the tray 40, which allows all the resistive forces resulting from the precise insertion thereof into the die-holder to be used.
the means for adjusting the position of the tray 40 may also consist of two elements, i.e. rear element 320 and front element 330, which are arranged coaxial with each other and the threaded bar 150 which in this case is arranged parallel to the longitudinal axis of the die-holder/tray assembly.
the rotation of the threaded bar 150 in one direction or the other causes the simultaneous displacement in one direction or the other of the two inserts and therefore the displacement of the tray 40 in the transverse direction.
Fig. 9 shows a further embodiment of the front insert 420 and rear insert 430 which in this case are a mirror-image of each other; in this configuration the respective female threads have oppositely directed threading so that operation of the threaded bar 150 which is again arranged parallel to the longitudinal axis of the die-holder/tray assembly causes a symmetrical movement of the two inserts towards/away from each other and therefore the displacement in one sense or the other along the transverse direction Y-Y of the tray 40.
the anti-rotation means have been illustrated positioned along the front edge of the die-holder/tray assembly, the position thereof in the longitudinal direction is not limiting and during practical implementation it will be taken into account that the greater the distance from the rear locking means the greater will be the resistance torque produced.
