Description
Technical field
The utility model relates to a kind of one-time-shaped mould of Z-type fingertip used for high-voltage switch.
Background technology
Z-type fingertip is the key components and parts in the high-voltage switch gear such as breaker, GIS electric equipment products, and its design and crudy directly have influence on the arc extinction performance of switch.The performance of Z-type fingertip is except design factor, depend primarily on material and the crudy of fingertip, the structure of Z-type fingertip is as shown in figure 12: Z-shaped fingertip 45 comprises fingertip body, the middle part of fingertip body has sweep 45-1, left blind hole 45-2 is provided with on the downside of the left end of fingertip body, be provided with right blind hole 45-3 on the downside of the right-hand member of fingertip body, the Axis Extension direction of left and right blind hole tilts to intersect, and the front and back bilateral symmetry of fingertip body is furnished with two ear 45-4 processed.At present, the Z-type fingertip that China's high-voltage switch gear uses is all that procurement cycle is long from external import, and parts cost is high, and this is that the long term growth of China's High-Voltage Electrical Appliances industry brings inconvenience.
The making of Z-type fingertip is a technical barrier of this area always, and the material of Z-type fingertip is copper, and copper is the metal of face-centered cubic lattice, changes, have higher plasticity, be suitable for extruded without ppolymorphism.Analysis is carried out from the manufacturability of part, key three positions of forming parts are left respectively, right blind hole, the ear processed of middle sweep and bilateral symmetry distribution, from without, technique is not very complicated, but due to workpiece small volume, the axis of two blind holes has the angle of certain angle, and blind hole and ear processed have required precision, analyze the flowing of metal in die cavity known, fingertip body both ends fill type mainly by the transfer of blind hole metal, a filling part for both sides ear is the transfer of right blind hole metal, a part is the transfer of left blind hole metal, from the path analysis of metal flow, the metal transfer of right blind hole is larger to the difficulty at ear place processed, therefore the filling of ear processed mainly keeps left the metal transfer at blind hole place, so the shaping of this part has certain difficulty, if also have workpiece first order buckling profile angle excessive, copper material workpiece will produce bending springback, cause the design shape and the performance requirement that are difficult to guarantee Z-type fingertip.
Utility model content
The purpose of this utility model is the one-time-shaped mould providing a kind of Z-type fingertip used for high-voltage switch, to solve the excessive and resilience problem easily caused of Z-type fingertip first order buckling profile angle.
In order to solve the problem, the technical solution of the utility model is:
The one-time-shaped mould of Z-type fingertip used for high-voltage switch, comprise one-shot forming upper male mould and the one-shot forming lower cavity die with one-shot forming die cavity, one-shot forming die cavity comprise left forming cavity, right forming cavity and be connected between left and right forming cavity with the sweep shape adaptation of corresponding Z-type fingertip bend to die cavity, be all horizontally disposed with at the bottom of the chamber of left and right forming cavity.
The compacted under be provided with at the bottom of the chamber of left forming cavity for the left blind hole of shaping Z-type fingertip is protruding, and one-shot forming upper male mould has the upper shaping projection of the right blind hole for shaping Z-type fingertip.
One-shot forming die cavity also comprises the ear forming cavity processed of the both sides ear for shaping Z-type fingertip be connected with left forming cavity.
One-shot forming die lower bolster is provided with on the downside of described one-shot forming lower cavity die, the forming convax mould that axis extends along the vertical direction is coated with in one-shot forming lower cavity die, one-shot forming die lower bolster coordinates with forming convax mould lower end block and moves down to limit forming convax mould, and described compacted under projection is made up of the upper end of described forming convax mould.
On described one-shot forming upper male mould, guiding movement is set with lower end for contacting the first flanging block pushing up press-fit with the epicoele opening's edge of one-shot forming die cavity, one-shot forming upper male mould is fixedly arranged on one-time-shaped mould upper bolster, is provided with the first flanging spring applying active force in downward direction to the first flanging block between one-time-shaped mould upper bolster and the first flanging block.
On described first flanging spring and one-time-shaped mould upper bolster, guiding is equipped with the first guide post, the lower end of the first guide post is fixed on described first flanging block, the upper end of the first guide post is provided with outer turning edge, and one-time-shaped mould moves down the limit with the spacing cooperation that turns edge with what limit the relative one-time-shaped mould upper bolster of the first guide post outward.
The beneficial effects of the utility model are: for avoiding Z-shaped fingertip one-shot forming angle excessive and the problem of easy bending springback, the forming process of Z-type fingertip is divided into two steps, blank is first squeezed into middle product by the first step, middle product is squeezed into final Z-type fingertip by second step, one-time-shaped mould in the utility model is the mould for realizing blank to be squeezed into middle product in a first step, because left, all be horizontally disposed with at the bottom of the chamber of right forming cavity, therefore in the middle of product left end bottom and be level bottom right-hand member, the left end of middle product is connected by sweep with right-hand member, post forming mould only need be used subsequently by bending for middle product right-hand member extruding, in the extruded process of one-time-shaped mould to blank, there is not the phenomenon that first order buckling profile angle is excessive, therefore the resilience problem of metal can effectively be avoided.
