Description
Technical field
The utility model relates to drawing die technical field, particularly relates to a kind of toilet basin transition segment negative sense drawing die.
Background technology
The structure of toilet basin is generally up big and down small, excreta is delivered to other positions by pipeline by bottom, coupling part sectional area to pipeline bottom toilet basin sharply reduces, and need to use cambered surface rounding off, general use transition segment connects toilet basin and pipeline, in order to avoid leaking, the most handy tube extrusion of transition segment is shaping.Fig. 1 is the structural representation of a kind of aviation closestool basin and transition segment, for saving space, the approximate horizontal layout of the pipeline be connected with toilet basin, causes transition segment to curving, if cause using extrusion die to extrude, the shaping rear workpiece of this crooked position cannot exit from mould.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of toilet basin transition segment negative sense drawing die, and it extrudes workpiece by deformable epoxy resin block in die, makes Workpiece shaping, and die cost is low, easy to process.
The utility model solves the technical scheme that its technical problem adopts: a kind of toilet basin transition segment negative sense drawing die, it comprises die shoe, die, punch, upper bolster, described die is fixedly connected with described die shoe, described die is provided with the die cavity corresponding with transition segment finished form, described punch comprises flexible epoxy resin block, the bottom of described punch is stretched in described die cavity, the top of described punch is provided with reserved boss, the fairlead be socketed on outside described reserved boss is provided with above described groove, the depression bar for described reserved boss being pressed into described die cavity is provided with on the downside of described upper bolster, described depression bar is socketed in described fairlead.
The top of described die cavity arranges the cylinder die cavity for holding non-stretched part.
The cumulative volume of described punch is 1.1 times of transition segment hollow space volume.
The top of described fairlead is provided with pressing plate, and when described depression bar comes downwards to minimum point, conflict the upside of described pressing plate in the downside of described upper bolster.
The beneficial effects of the utility model are: a kind of toilet basin transition segment negative sense drawing die, it comprises die shoe, die, punch, upper bolster, described die is fixedly connected with described die shoe, described die is provided with the die cavity corresponding with transition segment finished form, described punch comprises flexible epoxy resin block, the bottom of described punch is stretched in described die cavity, the top of described punch is provided with reserved boss, the fairlead be socketed on outside described reserved boss is provided with above described groove, the depression bar for described reserved boss being pressed into described die cavity is provided with on the downside of described upper bolster, described depression bar is socketed in described fairlead, the utility model scientific structure, forming shape is limited by die, deformable punch carries out extrusion stretching to workpiece, after machining, punch easily exits from die, this die cost is low, easy to use.

Detailed description of the invention
Being described in further detail the utility model below in conjunction with the drawings and specific embodiments, is not that practical range of the present utility model is limited to this.
Be illustrated in figure 1 the structural representation of transition segment 8 using state of the present embodiment processing, it is connected with two ends toilet basin 7, connecting plate 9.As shown in Figure 2, the toilet basin transition segment negative sense drawing die of the present embodiment, it comprises die shoe 1, die 2, punch 3, upper bolster 4, described die 2 is fixedly connected with described die shoe 1, described die 2 is provided with the die cavity 21 corresponding with transition segment finished form, described punch 3 comprises flexible epoxy resin block, the bottom of described punch 3 is stretched in described die cavity 21, gap is left between die cavity 21 and punch 3, the top of described punch 3 is provided with reserved boss 31, the fairlead 5 be socketed on outside described reserved boss 31 is provided with above described groove 2, the depression bar 6 for described reserved boss 31 being pressed into described die cavity 21 is provided with on the downside of described upper bolster 4, described depression bar 6 is socketed in described fairlead 5, the present embodiment scientific structure, by die 2 limit transition segment shaping after shape, deformable punch stretches in workpiece and carries out extrusion stretching to workpiece, after machining, punch easily exits from die, this die cost is low, easy to use.
Further, the top of described die cavity 21 arranges the cylinder die cavity for holding non-stretched part, and this cylindrical mold cavity is used for vertically putting into die cavity 21 when workpiece does not stretch, for cylindric when workpiece does not stretch.
Further, the cumulative volume of described punch 3 is 1.1 times of transition segment hollow space volume.
Further, the top of described fairlead 5 is provided with pressing plate 51, when described depression bar 6 comes downwards to minimum point, conflict the upside of described pressing plate 51 in the downside of described upper bolster 4, prevent in extrusion stretching process, excesssive gap between fairlead 5 and die 2, punch 3 is extruded from fairlead 5 and die 2.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
