Description
Technical field
The present invention relates to a kind of device for improving wedge service life.
Background technology
A kind of consumable accessory of the wedge as diel, it is in the industrial production, particularly extensive in Press Tools for Automobiles
Use.Its normal structure is made up of upper and lower base, drive block and sliding shoe.Wherein, when sliding shoe is complicated, more difficult whole
When body casting and machine-shaping, sliding shoe may be split into again slides two parts of block body and slide-and-guide block.
As shown in figure 1, in existing design, slide block body 2 and slide-and-guide block 1 and connected using rectangle key and screw
Connect, such a connected mode, horizontal groove is opened among slide-and-guide block 1, because the right angle of bottom land can produce stress concentration, cause
Wedge usually fails because of the fatigue fracture of slide-and-guide block 1.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of device for improving wedge service life, existing structure is changed
Enter, the stress for concentrating on a slide-and-guide block originally, be distributed to N（N is more than 1）On individual slide-and-guide block, and it is easy to process,
The effective guarantee service life of wedge.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of device for improving wedge service life, including lower bottom base and upper bed-plate, inclination is provided with the lower bottom base
Face, it is characterised in that at least two slide-and-guide blocks are evenly arranged with the inclined plane, between two neighboring slide-and-guide block
Be provided with slip block body, be sequentially arranged between the inclined plane and each slide-and-guide block V-arrangement guide plate and with V-arrangement guide plate phase
First drive block of engaging, the second drive block, second driving are provided between the inclined plane and each slip block body
The setting of block upper surface is fluted, and each block body lower surface of sliding is provided with corresponding projection.
It is preferred that slide-and-guide block and slip block body are arranged on the first drive block and the second drive block by screw respectively
On, the surface of slide-and-guide block and slip block body is located between top surface and the sliding shoe upper surface of same level and upper bed-plate
Angular range is 15-75 °.
It is preferred that the first drive block is in the boss-shaped of kidney-shaped.
It is preferred that it is in tabular to slide block body, the second drive block upper surface is provided with kidney-shaped groove.
The beneficial effects of the invention are as follows：
In traditional wedge structure, only one piece of slide-and-guide block, when wedge volume is relatively large, quality is relatively heavy
When, one piece of slide-and-guide block can not support upper bed-plate for a long time and it is moved in defined guide rail.The present invention is using at least
Two slide-and-guide blocks, which are replaced, slides block body, so in the case where general construction and small product size all do not change, solves
Deficiency in traditional Wedge mechanism, and it is easy to process.Tests prove that wedge of the present invention is in a work direction than traditional wedge
Tensile strength and fatigue resistance enhancing more than 50%, the effective guarantee service life of wedge.

Embodiment
Technical solution of the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that ability
The technical staff in domain can be better understood from the present invention and can be practiced, but illustrated embodiment is not as the limit to the present invention
It is fixed.
Fig. 1 is the wedge structure of existing design, and its corresponding connected mode is as shown in figure 3, slip block body 2 and slip are led
Rectangle key and screw connection are used to block 1, such a connected mode, horizontal groove are opened among slide-and-guide block 1, because of bottom land
Right angle can produce stress concentration, cause wedge usually to be failed because of the fatigue fracture of slide-and-guide block 1.Moreover, only one
Block slide-and-guide block, when wedge volume is relatively large, quality is relatively heavy, one piece of slide-and-guide block can not support for a long time
Base simultaneously makes it be moved in defined guide rail.
As shown in Figures 2 and 4, a kind of device for improving wedge service life, including lower bottom base 4 and upper bed-plate 3, the bottom
Inclined plane is provided with seat 4, at least two slide-and-guide blocks 1, two neighboring slide-and-guide are evenly arranged with the inclined plane
It is provided between block 1 and slides block body 2, namely slide-and-guide block 1 and slip block body 2 is to be staggered installation of.In Fig. 2, slip is led
It is 3 to the quantity of block 1, the quantity for sliding block body 2 is 2, wherein, 3 slide-and-guide blocks 1 are evenly distributed on inclined plane
Both sides and centre position, 2 are slided block body 2 and are arranged between two adjacent slide-and-guide blocks 1.
V-arrangement guide plate has been sequentially arranged between the inclined plane and each slide-and-guide block 1（Cross section is V-shaped）With with V-arrangement
