Description
Technical field
The present invention relates to a kind of measurement mechanism, specifically, relate to the horizontal drift hammer coaxality measuring mechanism of a kind of multi-ram forging hydropress.
Background technology
Multi-ram forging triple-valve body forging produce in, about hydropress two horizontal punch be arranged on respectively left and right horizontal perforation cylinder piston rod on and coaxial with its maintenance, and left and right horizontal bore a hole cylinder be arranged on machine frame inside both sides respectively.Because hydraulic press frame itself makes and alignment error, be difficult to ensure that left and right horizontal perforation cylinder piston rod right alignment numerical value is in desirable deviation range, is namely difficult to ensure that left and right two horizontal punch right alignment numerical value are in desirable deviation range.If use its horizontal punch right alignment numerical value of initial stage just to there is an enough large deviation at hydropress, even if this deviation numerically seems very little, but due to about 800 tons of the huge 40MN of its horizontal forging force, 120MN's is larger.Suppose that coaxiality deviation numerical value is 1mm, in reality, this numerical value may be run far deeper than.Now planar forces even number value is 800*1000*9.8*0.001=7840N*M.If the action effect of couple to upper punch is moment of flexure during this bias direction in the vertical direction, it is then moment of torsion time in the horizontal direction, and generally this bias direction is always between the two, so generally upper punch is subject to the effect of moment of flexure and moment of torsion simultaneously, just sometimes be subject to the effect of moment of flexure more greatly, be sometimes subject to the effect of moment of torsion more greatly.According to plane couple theory briefly, namely hydropress this couple when normal work can damage it by frequent repeat function on forging die, especially upper punch is comprised to the drift being in the condition of high temperature and horizontal punch causes serious fatigure failure, cause the generation of fatigue crack.Along with the impact that effect and the frame itself aborning by forging force is out of shape, this coaxiality deviation also has the trend expanded, this has a great impact (such as going up upright opening bias, lateral aperture decentraction etc.) the final forming dimension of forging, but the more important thing is, it has a strong impact on causing the serviceable life of forging die, not only reduce the bulk life time of forging die, and be one of major reason of impelling drift to rupture suddenly.Therefore, level monitoring drift coaxiality deviation numerical value also adjusts at any time becomes urgent task.
