An upper die is a male die with the upper part being inverted cone-shaped, and the projected part at the lower part of the upper die has the same shape with the interior part of the concave part of a finished part; a lower die consists of two symmetrically arranged half female dies with the same shape, and after the two half female dies are spliced together, the concave part of the spliced female dies has the same shape with the exterior part of the concave part of the finished part; the two half female dies are arranged in symmetry and can be clamped at the left and right ends of front and back support and positioning plates in a rotary manner; rebound limit assemblies of the two half female dies are respectively fixed between the front and back support and positioning plates which are located at the left lower corner and the right lower corner of the mould; a guide slot for the upper die is arranged at the middle position of the front or back support and positioning plate; a guide pin is fixed at the lower end of the upper die; and blank fixing assemblies are fixed above the front and back support and positioning plates. With the mould, the part under processing can be formed through single time of bending with high precision; the mould is free of the height limit of the part and can be demoulded automatically; the press tonnage requirement of the mould is lower; and no damage is caused to the structure of the material under processing.

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 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 merely operator's first order buckling to be shaped, and need repeatedly school shape, 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 again flexural deformation, 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 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, and the part that processes can not automatic demoulding, and the artificial demoulding is wasted time and energy, calotte shape part especially, the extractor assisted demoulding of Structure of need complexity.
Summary of the invention
Purpose of the present invention solves the above-mentioned problems in the prior art exactly, provide a kind of blank first order buckling that makes to be shaped, precision is high, and mould is 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 invention is: a kind of processing mold of sheet metal pipe clamp, and it comprises upper die and lower die, supporting and location 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; Counterdie by identical, symmetrical two splicings of shape after recess half die identical with the external shape of the part negative area that is processed into form; The thickness of upper die and lower die is not less than the thickness of blank, after the two is combined, between the slit be the workpiece shape that is processed into; The supporting and location seat is comprised of the back and front supporting location-plate, and two and half dies are symmetrical and rotatably be clamped in the left and right two ends of back and front supporting location-plate; Be fixed with respectively the resilience limit assembly of two and half dies 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 front or the rear support location-plate 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, the lower end of the left and right center line of patrix is fixed with guide finger, and after the installation, guide finger is positioned at gathering sill; Between patrix and two and half dies, be fixed with the blank fixation kit on the upper left side of two and half dies and the top-right back and front supporting location-plate.
Blank fixation kit described above comprises horizontal strip hole, pinching screw and the pad that has on front or the rear support location-plate.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 larger, the scope of application is wider, 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 pinching screw is fixed in the positioning key by pad, and the top holds out against on blank.
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, is fixed with torsion spring fixed leg and torsion spring limited post on two and half dies of this end below; 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 present invention remedies 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 consistent 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 the 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 simultaneously bending force, 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 larger torsion spring of elastic force, makes the easier demoulding of workpiece of processing.The gathering sill of supporting and location seat and patrix and the structure of guide finger, when crooked, guide-localization is more accurate.The present invention is not subjected to the restriction of spares bend height.
In a word, the present invention can make the part to be processed first order buckling be shaped, and precision is high, and mould is 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, therefore required press tonnage is lower, do not damage the rapidoprint self structure.
