Abstract
The utility model discloses a kind of durable Wedge mechanism, comprise upper bed-plate, drive block, sliding shoe, it is characterized in that: described sliding shoe comprises sliding shoe body, slide-and-guide piece, described slide-and-guide piece bottom is provided with boss, and described slide-and-guide piece top is provided with screw via hole; Described sliding shoe body is provided with the groove matching with boss, and described bottom portion of groove arranges screwed hole; Described screw is connected with the screwed hole in sliding shoe body recess through the screw via hole of slide-and-guide piece.Described boss is set to ellipsoidal structure, and described groove is set to the ellipsoidal structure matching with boss.The durable Wedge mechanism of one that the utility model provides, simple in structure, easy to process.In the direction of motion, shearing force is disperseed along circular arc, avoids stress to concentrate.Through evidence, direction of motion tensile strength and fatigue resistance more than 30%, have effectively extended the service life of Wedge mechanism than common cross key slot type link enhancement.
Description
Technical field
The utility model relates to a kind of durable Wedge mechanism, belongs to die assembly technical field.
Background technology
Wedge mechanism, as a kind of consumable accessory of diel, in industrial production, is particularly widely used in Press Tools for Automobiles.Its normal structure is made up of upper bed-plate, drive block and sliding shoe three parts.Wherein, in the time of sliding shoe complex structure, sliding shoe is difficult to monoblock cast and machine-shaping, so often sliding shoe is split into sliding shoe body, two parts of slide-and-guide piece.As shown in Figure 1, sliding shoe body and slide-and-guide piece tradition connected mode are to connect with rectangle key and screw.This connected mode, will open horizontal groove in the middle of slide-and-guide piece, concentrates because the right angle place of bottom land can produce stress, causes wedge usually because the fatigue fracture of slide-and-guide piece was lost efficacy.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of durable Wedge mechanism.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of durable Wedge mechanism, comprises upper bed-plate, drive block, sliding shoe, and described sliding shoe comprises sliding shoe body, slide-and-guide piece, and described slide-and-guide piece bottom is provided with boss, and described slide-and-guide piece top is provided with screw via hole; Described sliding shoe body is provided with the groove matching with boss, and described bottom portion of groove arranges screwed hole; Described screw is connected with the screwed hole in sliding shoe body recess through the screw via hole of slide-and-guide piece.
Described boss is set to ellipsoidal structure, and described groove is set to the ellipsoidal structure matching with boss.
As preferred version, described screw via hole, screwed hole quantity are all set to two.
Beneficial effect: the durable Wedge mechanism of one that the utility model provides, simple in structure, easy to process.In the direction of motion, shearing force is disperseed along circular arc, avoids stress to concentrate.Through evidence, direction of motion tensile strength and fatigue resistance more than 30%, have effectively extended the service life of Wedge mechanism than common cross key slot type link enhancement.
Brief description of the drawings
Fig. 1 is the structural representation of sliding shoe tradition connected mode;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the top view of slide-and-guide piece;
Fig. 4 is sliding shoe structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 2, Figure 3, Figure 4, a kind of durable Wedge mechanism, comprises upper bed-plate 1, drive block 2, sliding shoe, and described sliding shoe comprises sliding shoe body 3, slide-and-guide piece 4, described slide-and-guide piece 4 bottoms are provided with boss 5, and described slide-and-guide piece 4 tops are provided with screw via hole; Described sliding shoe body 3 is provided with the groove 6 matching with boss 5, and described groove 6 bottoms arrange screwed hole; Described screw 7 is connected with the screwed hole on sliding shoe body 3 grooves 6 through the screw via hole of slide-and-guide piece 4.
Described boss 5 is set to ellipsoidal structure, and described groove 6 is set to the ellipsoidal structure matching with boss 5.
As preferred version, described screw via hole, screwed hole, screw 7 quantity are all set to two.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
