The specific embodiment
The mould schematic perspective view that has flexible die that Fig. 1 provides for the utility model embodiment, Fig. 2 treat towards the workpiece sketch map for the mould that has flexible die using the utility model embodiment and provide, the structural representation of the partly cut-away of the mould that has flexible die that Fig. 3 provides for the utility model embodiment; Fig. 4 is the partial enlarged drawing of Fig. 3, and the utility model embodiment provides a kind of mould that has flexible die, is applicable to the punching press of sheet material spare; For example; Can be used for as shown in Figure 2 the treating towards workpiece 8 of punching press, wherein this mould comprises upper bolster 1 and die shoe 2, and upper bolster 1 can be used as die and uses; Treat towards workpiece 8 and carry out punching press; This upper bolster 1 has a cavity under shed, is set with cushion 3 in the cavity, and the shape of cavity can be set with actual conditions; For easy to process, can be set to as shown in Figure 1 rectangular-shaped; The upper surface of die shoe 2 is used to install punch 9, and the upper end of this die shoe 2 can cooperate in the cavity that inserts upper bolster 1, and when cavity is set to when rectangular-shaped, die shoe 2 upper ends also relative set are rectangular-shaped; When upper bolster 1 and die shoe 2 closures, the die shoe 2 that punch 9 is installed inserts cavitys, and upper bolster 1 moves downward under the effect of forcing press, the workpiece on the cushion 3 extruding punch 9, thus make Workpiece shaping.Because cushion 3 can be with treating that the shape towards workpiece 8 pushes variation,,, practiced thrift cost so when the trial-production of new product, workpiece size is carried out also mold exchange more of certain change even some error of the size of a collection of workpiece also can adaptively be fitted.
When cushion 3 was fixed in the cavity, along with lifting of upper bolster 1, cushion 3 had the danger that comes off; For this reason, the mould that has flexible die that present embodiment provides also is provided with stopping means, like Fig. 3 and shown in Figure 4; This stopping means comprises spacer pin 4 and wedge block 5, and spacer pin 4 is kept out below cushion 3, and this spacer pin 4 passes the side wall surface of cavity; And expose from the internal face of cavity, its exposed portions serve is set to inclined-plane 15; Correspondingly, wedge block 5 is embedded on the sidewall of die shoe 2 upper ends, when upper bolster 1 descending; The inclined-plane 15 of spacer pin 4 produces relatively with wedge block 5 and slides; Spacer pin 4 stressed retractions do not move downward thereby can not influence upper bolster 1, when upper bolster 1 runs to a high position; Cushion 3 can not deviate under the effect of spacer pin 4, has improved the reliability of work.
Wherein the retraction of spacer pin 4 is realized in the following manner: as shown in Figure 4, and spacer pin 4 is set is the multidiameter shape, its end near the cavity inner wall face is big footpath 13; End near the chamber outer wall face is a path 14, is provided with spring 10 in the outer cover of path 14, correspondingly; Cavity wall is offered the hole that supplies spacer pin 4 to pass and also is set to stepped; And the outside wall surface of cavity is fixed with spring stop piece 11, to keep out spring 10, prevents that spring 10 from coming off.
In the present embodiment, the upper surface of die shoe 2 also is set with counterdie backing plate 12, and the upper end sidewall of the sidewall of counterdie backing plate 12 and die shoe 2 forms the side that is connected as a single entity, and said wedge block 5 is embedded on this side.According to the difform punch 9 of practical application, can change counterdie backing plate 12, when changing counterdie backing plate 12, pull down wedge block 5 earlier, change again.
The working state schematic representation of the mould that has flexible die that Fig. 5 provides for the utility model embodiment; As shown in Figure 5, adopt the mould of said structure, as long as the corresponding simple convex 9 of want shaping workpiece is installed on the counterdie backing plate 12; To treat again to be placed on the punch 9 towards workpiece 8; When mould closes, utilize the extrusion modling of 3 pairs of workpiece of cushion, can solve punching press different size workpiece and the problem of frequent change punch-die; And the surface of the work of cushion 3 extrusion modlings do not have scuffing, and quality is higher.
Preferably, upper bolster 1 has patrix flange 6, and patrix flange 6 can be fixedly connected with upper bolster 1, also can be one-body molded, be used for upper bolster 1 is fixedly connected on the lower surface of forcing press upper table.
Likewise, die shoe 2 has counterdie flange 7, is used for die shoe 2 is fixedly connected on the upper surface of forcing press lower table.
Further, cushion 3 can be selected rubber blanket commonly used in the prior art, highly versatile for use.
The mould that has flexible die that the utility model embodiment provides is through being provided with cavity at upper bolster; In cavity, fixedly install cushion, when stamped workpieces, because cushion can be with the variable characteristics of the workpiece elasticity of shape; When making the stamping parts of punching press different size; Needn't the frequent change die, the mould highly versatile has reduced production cost.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
