Description

The processing mold of sheet metal pipe clamp
Technical field
The present invention relates to a kind of machining equipment, particularly a kind of sheet metal pipe clamp processing mold for fixing metal pipe fitting.
Background technology
At present, the machining of sheet metal class pipe clamp part relies on merely operator's direct bending forming more difficult, and need school shape repeatedly, and interchangeability is poor, and the used time is longer, substantially can not meet design drawing requirement, and production efficiency is low.Utilize existing Mould Machining sheet metal class pipe clamp part, its technical process adopted is blanking, bending forming, reparation and boring; Its pipe clamp processed is all right angle and straight flange, need artificial flexural deformation again, and especially pipe clamp transition angle is arc, manually again processes very difficult; The top of patrix is cylindricality, its strength pressed on blank is even, position due to exterior angle, arc-shaped transition angle sweep is change in BENDING PROCESS, material has elongation phenomenon when bending, its outer angular shape is inaccurate, easily there is buckling deformation phenomenon in vertical edge whole part that is thinning, that process, mould is only applicable to the not too high occasion of spares bend height; And the counterdie of this mould is unit construction mo(u)ld, the part processed can not automatic demoulding, and the artificial demoulding is wasted time and energy, especially calotte shape part, the extractor assisted demoulding of Structure of need complexity.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, there is provided one can make blank direct bending forming, precision is high, and mould is not by spares bend height limitation, can automatic demoulding, do not damage the processing mold of the sheet metal pipe clamp of rapidoprint self structure.
For achieving the above object, technical solution of the present invention is: a kind of processing mold of sheet metal pipe clamp, and it comprises upper die and lower die and supporting and location seat; It is characterized in that: it also comprises blank fixation kit and resilience limit assembly; Patrix is the punch that a top is back taper, lower projections position is identical with the interior shape of the part negative area be processed into; Half die that after two splicings that counterdie is identical by shape, symmetrical, recess is identical with the outer shape of the part negative area be processed into forms; The thickness of patrix and the thickness of counterdie are not less than the thickness of blank, after upper die and lower die are combined, between gap be the workpiece shapes be processed into; Supporting and location seat is made up of back and front supporting location-plate, and two and half dies are symmetrical and be rotatably clamped in the left and right two ends of back and front supporting location-plate; Be fixed with the resilience limit assembly of two and half dies between back and front supporting location-plate, the resilience limit assembly on the left side is positioned at the lower left corner of half die of left end, and the resilience limit assembly on the right is positioned at the lower right corner of half die of right-hand member; Inwall that is front or rear support location-plate has the gathering sill of patrix in the position on the left and right axis of symmetry top being positioned at two and half dies, the lower end of the left and right center line of patrix is fixed with guide finger, and after installation, guide finger is positioned at gathering sill; Blank fixation kit, between patrix and two and half dies, is fixed on the top-right back and front supporting location-plate of the upper left side of half die of left end, half die of right-hand member; Described resilience limit assembly comprises and is fixed on limited block between back and front supporting location-plate and torsion spring; The inner end of limited block withstands on half die of left end or right-hand member, the back and front supporting location-plate below this end is fixed with torsion spring fixed leg and torsion spring limited post; Torsion spring is fixed on torsion spring fixed leg, and its one end is supported on limited block, and the other end is supported on half die of left end or right-hand member.
blank fixation kit described above comprises horizontal elongate holes, pinching screw and pad that front or rear support location-plate have.During use, first blank is clipped between back and front supporting location-plate, and aim at elongate holes, after mixing up the center of blank, held out against fixing by pinching screw and pad, the setting of elongate holes, the length range making it adapt to blank is larger, the scope of application is wider, facilitates the position adjustment of blank and fixes.
It is the positioning key that square, corresponding with the pinching screw inwall that matches with elongate holes and pinching screw match that blank fixation kit described above also comprises profile; During use, positioning key is placed in elongate holes, and pinching screw is fixed in positioning key by pad, and top holds out against on blank.
The present invention makes up the resilience occurred in brake forming process, by in an inverted cone for punch upper design, when expecting under shear, take into full account the rebound direction of bool and the size of springback capacity, to ensure the consistent of springback capacity, simultaneously by calculating springback capacity, mould carries out strengthen or reduce compensation rate.Punch top is done in an inverted cone, reduces the pressure to vertical edge in punching course, avoid as far as possible vertical edge thinning, avoid whole part to occur the phenomenon such as buckling deformation, ductile rupture.Counterdie adopts split-type design, reduces the friction of part to be processed and counterdie, is convenient to part location.Greatly reduce bending force, required press tonnage is less simultaneously.Adopt resilience limit assembly, make the part be processed into achieve automatic demoulding, especially resilience assembly uses the torsion spring that elastic force is larger, makes the easier demoulding of the workpiece of processing.The gathering sill of supporting and location seat and patrix and the structure of guide finger, time bending, guide-localization is more accurate.The present invention is not by the restriction of spares bend height.
In a word, the present invention can make part to be processed direct bending forming, and precision is high, and mould is not by spares bend height limitation, can automatic demoulding, and in forming process, material does not stretch phenomenon, only need pure bending power, therefore required press tonnage is lower, does not damage rapidoprint self structure.
