Description
Technical field
The present invention relates to a kind of measuring devices, are to be related to a kind of horizontal drift hammer of multi-ram forging hydraulic press specifically
Coaxality measuring mechanism.
Background technology
In the production of multi-ram forging triple-valve body forging, two horizontal punch of hydraulic press or so is separately mounted to left and right horizontal and wears
Keep coaxial on the cylinder piston rod of hole and with it, and left and right horizontal perforation cylinder is separately mounted to machine frame inside both sides.Due to hydraulic press
Rack makes and in itself the reason for installation error, it is difficult to ensure that left and right horizontal is perforated, cylinder piston rod concentricity numerical value is preferably partially
In poor scope, i.e., it is difficult to ensure that two horizontal punch concentricity numerical value of left and right are in preferable deviation range.If make in hydraulic press
With initial stage, its horizontal punch concentricity numerical value there is a sufficiently large deviation, even if this deviation numerically seems very
It is small, but due to about 800 tons of its horizontal huge 40MN of forging force, the bigger of 120MN.Assuming that coaxiality deviation numerical value is 1mm,
This numerical value may be run far deeper than in practice.Planar forces even number value is 800*1000*9.8*0.001=7840N*M at this time.This
If bias direction in the vertical direction when couple be moment of flexure to the effect of upper punch, in the horizontal direction when if be turn round
Square, and this bias direction is always between the two under normal circumstances, thus under normal circumstances upper punch simultaneously bending moment and
The effect of torque, simply the effect of bending moment sometimes more greatly, sometimes by torque effect more greatly.It is sketched according to plane couple is theoretical
It, i.e., hydraulic press in normal work this couple can frequent repeat function on forging die so as to be damaged to it, especially
It is to cause serious fatigue rupture including upper punch and horizontal punch to being in the punch of the condition of high temperature, causes the production of fatigue crack
It is raw.Influenced as the effect in production by forging force and rack deform in itself, this coaxiality deviation also have it is widened become
Gesture, this has a great impact to the final forming dimension of forging（Such as upper upright opening bias, lateral aperture decentraction etc.）, but it is heavier
It wants, it can cause to seriously affect to the service life of forging die, not only reduce the bulk life time of forging die, and be to promote to rush
The one of the major reasons that head process is so broken.Therefore, level monitoring punch coaxiality deviation numerical value and at any time adjustment become urgent
Business.
