Description
Technical field
The utility model relates to a kind of machining equipment, particularly a kind of sheet metal pipe clamp processing mold for the fixing metal pipe fitting.
Background technology
At present, it is relatively more difficult that the machining of sheet metal class pipe clamp part relies on operator's first order buckling to be shaped merely, and need school shape repeatedly, and interchangeability is relatively poor, and the time spent is longer, does not substantially satisfy the design drawing requirement, and production efficiency is low.Utilize existing Mould Machining sheet metal class pipe clamp part, its technical process that adopts is blanking, bending forming, reparation and boring; Its pipe clamp that processes all is right angle and straight flange, and needing manually flexural deformation again, especially pipe clamp transition angle is arc, and manually processing is very difficult again; The top of patrix is cylindricality, its strength that presses on the blank is even, because the position of exterior angle, arc-shaped transition angle sweep changes in BENDING PROCESS, material has the elongation phenomenon when bending, its outer angular shape is inaccurate, vertical edge attenuation, the whole part that processes are prone to the buckling deformation phenomenon, and mould only is applicable to the occasion that the spares bend height is not too high; And the counterdie of this mould is unit construction mo(u)ld, and the part that processes can not automatic demoulding, and the artificial demoulding is wasted time and energy, and especially calotte shape part needs the auxiliary demoulding of baroque extractor.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provide a kind of blank first order buckling that makes to be shaped, precision height, mould are not subjected to the spares bend limitation in height, 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 utility model is: a kind of processing mold of sheet metal pipe clamp, and it comprises upper die and lower die, supports positioning seat, blank fixation kit and resilience limit assembly; Patrix is that a top is back taper, outstanding position, the bottom punch identical with the interior shape of the part negative area that is processed into; Recess half die identical with the external shape of the part negative area that is processed into formed after two splicings that counterdie is identical by shape, be symmetrically distributed; The thickness of upper die and lower die is not less than the thickness of blank, after the two lumps together, between the slit be the workpiece shape that is processed into; Support positioning seat and be made up of the back and front supporting location-plate, two and half dies are symmetrically distributed and also rotatably are clamped in the left and right two ends of back and front supporting location-plate; The resilience limit assembly that two and half dies are fixedly arranged respectively between the back and front supporting location-plate in the lower right corner of the lower left corner of half die of left end, half die of right-hand member; Inwall preceding or the back support positioning plates has the gathering sill of patrix in the position on the left and right axis of symmetry top that is positioned at two and half dies, fixedly there is guide finger the lower end of the left and right center line of patrix, and after the installation, guide finger is positioned at gathering sill; Between patrix and two and half dies, on the upper left side of two and half dies and the top-right back and front supporting location-plate blank fixation kit is arranged fixedly.
Blank fixation kit described above comprises horizontal strip hole, pinching screw and the pad that has on preceding or the back support positioning plates.During use, at first blank is clipped between the back and front supporting location-plate, and aligning strip hole, after mixing up the center of blank, by pinching screw and pad it is held out against fixing, the setting in strip hole, the length range that makes it adapt to blank is bigger, the scope of application is wideer, makes things convenient for the position of blank to adjust and fixing.
Blank fixation kit described above comprises that also profile is the positioning key that square, the inwall that is complementary with the strip hole and pinching screw are complementary; During use, positioning key places in the strip hole, and in positioning key, the top holds out against on blank pinching screw by spacers.
Resilience limit assembly described above comprises limited block and the torsion spring that is fixed between the back and front supporting location-plate; The inner end of limited block withstands on one of them half die, on two and half dies of this end below torsion spring fixed leg and torsion spring limited post is arranged fixedly; Torsion spring is fixed on the torsion spring fixed leg, and the one end is supported on the limited block, and the other end is supported on one of them half die.
The utility model is to remedy the resilience that occurs in the brake forming process, the punch upper design is in an inverted cone, when shearing blanking, take into full account the rebound direction of bool and the size of springback capacity, to guarantee the unanimity of springback capacity, simultaneously by calculating springback capacity, strengthen or reduce compensation rate at mould.Punch top is done in an inverted cone, has reduced in punching course the pressure of vertical edge, avoid as far as possible vertical edge attenuation, avoid whole part phenomenons such as buckling deformation, ductile rupture to occur.Counterdie adopts split-type design, reduces the friction of part to be processed and counterdie, is convenient to the part location.Greatly reduce bending force simultaneously, required press tonnage is less.Adopt the resilience limit assembly, make the part that is processed into realize automatic demoulding, especially the resilience assembly uses the bigger torsion spring of elastic force, makes the easier demoulding of workpiece of processing.Support positioning seat and the gathering sill of patrix and the structure of guide finger, when crooked, guide-localization is more accurate.The utility model is not subjected to the restriction of spares bend height.
In a word, the utility model can make the part to be processed first order buckling be shaped, and precision height, mould are not subjected to the spares bend limitation in height, can automatic demoulding, and in the forming process, the material phenomenon that do not stretch, only need pure bending power, so required press tonnage is lower, do not damage the rapidoprint self structure.
