Background technology
Nearly ten years, the automobile light weight with the high speed development of automobile industry, with global energy-conservation, low-carbon (LC), reduction of discharging as purport
Change, become the important topic of automobile industry development.Global Ge great main engine plants give sufficient strength, lower big work(all on body lightening
Husband, carbon fiber therein, aluminium alloy and high just plate, become the main direction of studying of automotive light weight technology.
In body of a motor car, body structural member as important in A, B, C post, collision prevention girders, front/rear collision bumper etc., for adapting to lightweight
Require, how using high just plate more than tensile strength 800Mpa.And the press capacity reply tensile strength of traditional Wedge mechanism
The steel plate of below 500MPa still, towards the punching press of high just plate, then due to the intensity of Wedge mechanism itself and unloading performance not
Foot so that the high just punching deburring of plate inefficient it is impossible to form synchronization with normal metal punching.
Above-mentioned this traditional Wedge mechanism has been widely used nearly hundred in stamping press field, especially automobile stamping field
Year, in the face of high just plate punching press, traditional Wedge mechanism has following deficiency：The drive block of the main element of mechanism, take-up housing, slide block etc.
Multiselect cylinder iron material, the strength grade of its material cannot break through more than tensile strength 800MPa, then this Wedge mechanism exists
The ability completing the anti-load impacting of Sheet Metal Forming Technology is just greatly limited.
The lubricating system of traditional Wedge mechanism, adopts no oil supply mode, that is, more：By arranging on the sliding surface of friction pair
Graphite pores add graphite and immersion oil is processed.So, copy the relative slip of friction pair, the heat of generation makes to be immersed in graphite hole gap
Saturation oil molecule overflow, play certain lubrication.But the oil molecule in the graphite hole gap that immersion oil is processed after all is limited, makes
After using certain jig frequency, lubricant effect can become, not as the past, the impaired aggravation of rubbing surface, to accelerate the initial failure of Wedge mechanism.
Again due to some graphite pores having been opened on friction pair, impact certainly will be produced on friction pair individuality intensity, 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 slide block, angle design is usual
For 120 °, so it is applied to the moment of flexure on two V-type faces, big with respect to the V-type face of larger angle design, and the face tolerating
Pressure is relatively small, and this is also the main cause causing slide block initial failure.
