Description

A kind of floating type evagination wrap molding mould
Technical field
The utility model relates to a kind of mould, especially relates to a kind of floating type evagination wrap molding mould.
Background technology
In industries such as electronics, electrical equipment, medical treatment, automobile, instrument, instrument, there is the power transmission shaft end of many power set usually will design dustproof end cap, convenient in order to guarantee installation and maintenance, general end cap adopts process of sheet forming, and outside 3~4 of drawing part sidepiece designs convex closure, be used for and the groove interference fit at seal shaft end place, be used for blocking end cap.Be shaped for the normal method that adopts vertical belling bag and calibration to combine of the outer convex closure of end cap at present, the position of 3~4 convex closures is difficult to guarantee as a result, and the convex closure size that extrudes is inhomogeneous, and it is inconsistent that the result assembles the back tightness; If adopt polyamine fat rubber to come bulging, because the convex closure size is little, unit pressure is excessive, is difficult for realizing; Because this class die forming must be implemented on mechanical press, so noise is big, the cost height.
The utility model content
The purpose of this utility model be exactly provide a kind of stable and reliable operation in order to overcome the defective that above-mentioned prior art exists, the convex closure size and dimension precision height after being shaped, and the floating type evagination wrap molding mould that can reduce noise pollution, reduce production costs.
The purpose of this utility model can be achieved through the following technical solutions: a kind of floating type evagination wrap molding mould, it is characterized in that, this mould is mainly by the patrix pressure head, counterdie is formed, described counterdie comprises standing part and floating part, floating part is arranged on standing part inside, described standing part comprises cover plate, overcoat, bearing, seat board, shaped bar, described bearing is arranged on the seat board, described outer being set on the bearing, described cover plate is connected with overcoat, described shaped bar is fixedlyed connected with seat board, described floating part comprises floating bushing, spring, location-plate, floating punch, floating cavity die, described floating bushing is set on the shaped bar, described location-plate is set on the shaped bar, and is connected with floating bushing, described floating punch, floating cavity die and floating bushing are slidingly connected, be provided with spring between described floating cavity die and the floating bushing, be provided with spring between described floating bushing and the bearing.
Be connected and fixed by interference between described shaped bar and the seat board.
This mould also comprises backing plate, and backing plate is arranged on the below of seat board.
Compared with prior art, the utlity model has following advantage:
1, for high-quality, high efficiency, the outer convex closure end cap class part of low-cost production provide a kind of new equipment, has very high use value;
2, the design by floating type punch and die, and move up and down in conjunction with floating bushing cooperates the conical surface of overcoat and shaped bar again, form accuracy, dimensional accuracy and the positional precision of the back convex closure that guaranteed accurately to be shaped;
3, movable part all adopts to be slidingly matched and has guaranteed the stationarity and the functional reliability of motion;
4, the last mode structure of traditional moulds that adopted this designs simplification can be realized punching press on pneumatic or gas-liquid pressure-boosting forcing press, avoided adopting that traditional punching machine implements that the punching press noise is big, troublesome poeration, defect of high cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is that seat board, 2 is that shaped bar, 3 is that location-plate, 4 is that floating cavity die, 5 is that spring, 6 is that pressure head, 7 is that cover plate, 8 is that floating punch, 9 is that floating bushing, 10 is that overcoat, 11 is that bearing, 12 is that backing plate, 13 is a straight pin among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of floating type evagination wrap molding mould is made up of patrix pressure head 6 and counterdie, and counterdie is made up of standing part and floating part.
Standing part is made up of cover plate 7, overcoat 10, bearing 11, backing plate 12, straight pin 13, seat board 1, shaped bar 2.Cover plate 7 adopts four screws to be connected with overcoat 10; Shaped bar 2 adopts interference fit to fix with seat board 1; Seat board 1, bearing 11, backing plate 12 and seat board 1 adopt four screws to fix and 2 straight pin 13 location; The Top Runby of cover plate 7 restriction floating bushings 9, the inner conical surface of overcoat 10 provides the displacement of floating cavity die 4, and the conical surface of shaped bar 2 provides the compression distance of floating punch 8.
Floating part is made up of floating bushing 9, spring 5, location-plate 3, floating punch 8, floating cavity die 4 etc.Adopt interference fit between location-plate 3 and the floating bushing 9; Adopt between floating bushing 9 and the floating cavity die 4 to be slidingly matched, rely on spring 5 to reset; Adopt between floating bushing 9 and the overcoat 10 to be slidingly matched, adopt little matched in clearance between floating bushing 9 and the bearing 11, rely on spring 5 to reset; Between floating punch 8 and the floating bushing 9 for being slidingly matched; For being slidingly matched, be pressed into the convex closure degree of depth between shaped bar 2 upper ends and the location-plate 3 by the control of the conical surface on it.After standing part and the floating part assembling, drive corresponding floating cavity die 4 and floating punch 8, guaranteed to extrude the form accuracy and the degree of depth uniformity of convex closure by the conical surface of floating bushing 9 and the conical surface of shaped bar 2.
When using this device, blank material behind the pull and stretch is inserted on the location-plate 3, pressure head 6 descending drive location-plates 3 and floating bushing 9 are descending, subsequently floating cavity die 4 along perpendicular square to moving, displacement is by the control of the conical surface in the overcoat 10, compress blank, then, floating punch 8 along continuous straight runs move finishes the convex closure shaping, displacement is by the conical surface control of shaped bar 2, get off, pressure head 6 is up, and spring 5 is with floating bushing 9 jack-up, spring 5 is released floating cavity die 4 levels, taking-up is behind part, and floating punch 8 moves inward, and whole process finishes.
