Description
Technical field
The present invention relates to high just plate punch forming technical field, more particularly to a kind of compact high-rigidity Wedge mechanism.
Background technology
Nearly ten years, with the high speed development of automobile industry, using global energy-conservation, low-carbon, emission reduction as purport automobile light weight
Change, turn into the important topic of automobile industry development.The major main engine plants in the whole world are all on body lightening to sufficient strength, lower big work(
Husband, carbon fiber therein, aluminium alloy and high firm plate, turn into the main direction of studying of automotive light weight technology.
In body of a motor car, such as important body structural member of A, B, C post, collision prevention girders, front/rear collision bumper, to adapt to lightweight
It is required that use more than tensile strength 800Mpa high firm plate more.And the press capacity reply tensile strength of traditional Wedge mechanism
Below 500MPa steel plate is fine, towards the punching press of high just plate, then due to Wedge mechanism itself intensity and unloading performance not
Foot so that the high just punching deburring of plate it is inefficient, can not be formed with normal metal punching synchronous.
Above-mentioned this traditional Wedge mechanism has been widely used nearly hundred in stamping press field, especially automobile stamping field
Year, there is following deficiency in face of high just plate punching press, traditional Wedge mechanism：The drive block of the main element of mechanism, take-up housing, sliding block etc.
Cylinder iron material, the strength grade of its material can not be broken through more than tensile strength 800MPa multiselect, then this Wedge mechanism exists
The ability for completing the anti-load impacting of Sheet Metal Forming Technology is just greatly limited.
The lubricating system of traditional Wedge mechanism, it is more using without oil supply mode, i.e.,：By being set on the sliding surface of friction pair
Graphite pores addition graphite and immersion oil processing.So, the relative slip of friction pair is copied, caused heat to be immersed in graphite hole gap
Saturation oil molecule overflow, play certain lubrication.But the oil molecule after all in the graphite hole gap of immersion oil processing is limited, makes
After using certain jig frequency, lubricant effect can become to aggravate not as in the past, rubbing surface is damaged, and accelerate the initial failure of Wedge mechanism.
Again due to having opened some graphite pores on friction pair, friction pair individual intensity certainly will be had an impact, this is also to make
Obtain the weak point of the high just plate Sheet Metal Forming Technology of traditional Wedge mechanism reply.
Traditional Wedge mechanism, for playing the V-type guide plate of Self-centering Action and the V-type face of sliding block, angle design is usual
For 120 °, the moment of flexure being so applied on two V-type faces, relative to the V-type face of larger angle design face that is big, and being resistant to
Press relatively small, this is also the main reason for causing sliding block initial failure.
The content of the invention
In order to overcome the weak point of the high just plate punching press of above tradition Wedge mechanism reply, it is an object of the invention to provide one
Kind can be applicable the compact high-rigidity Wedge mechanism of high just plate punch forming technology.
The used to achieve the above object technical scheme of the present invention is：A kind of compact high-rigidity Wedge mechanism, it is special
Sign is：Upper slide and baffle plate are connected on take-up housing, connects compact strength nitrogen spring on sliding block, take-up housing passes through with sliding block
Two sideskids connect and compose the execution unit of Wedge mechanism；V-type guide plate connects and composes the driving list of Wedge mechanism with drive block
Member；Driver element is connected by anti-wedge arm-tie with execution unit, and drives execution unit to realize compact Wedge mechanism to Gao Gang
The punching press of plate；
The place of being slidably matched of the sideskid and sliding block optimizes processing using semi-circular structure, and oiling is set on sideskid
Mouthful, corresponded on pouring orifice and pump nozzle is installed, at the interactive cooperation by pump nozzle oil supply to sideskid and sliding block；
Pouring orifice is set on the take-up housing, installation pump nozzle is corresponded on pouring orifice, between take-up housing and sliding block
Upper slide is provided with the cross-drilled hole and vertical hole of corresponding pump nozzle and sliding block top surface oil groove, lubricating oil is injected by pump nozzle, by horizontal stroke
Hole and vertical hole are implemented the slip to the upper slide on sliding block and take-up housing and lubricated in oil groove；
