Inner chamber 501 is provided with 500, the upper end of saw tooth 300 is stretched into the inner chamber 501 of connecting rod 500, and the lower end for sawing tooth 300 passes through ball
First 301 are engaged with the ball seat 700 in worm gear case 600, and sliding block is fixed on worm gear case 600, but the structure has following ask
Topic：
（1）, the adjustment amount that moves up and down of saw tooth be restricted, i.e., mould height adjustment amount is restricted, and is ensureing connecting rod and saw
On the premise of tooth intensity, its mould height adjustment amount is general within 300mm；
（2）, connecting rod punch crank drive under amplitude of fluctuation be restricted；
（3）, saw tooth lower end bulb and ball seat between contact sphere requirement on machining accuracy it is very high, difficulty of processing is big；
（4）, saw tooth and saw tooth nut between lubrication be not suitable for using thin oil lubricant, can only use grease lubrication, but its moisten
Sliding effect is general.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of larger high adjustment amount of mould, high lubricating effect and added
The mould height adjusting device of the simple punch press of work.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of mould height adjusting device of punch press,
Including worm gear case, saw tooth, saw tooth nut and connecting rod, described worm gear case is fixedly connected with slider of punch, in described worm gear case
The worm gear being meshed and worm screw are provided with, described saw tooth nut is arranged in described worm gear case and relatively described worm gear case
Axial restraint, described worm gear is coaxially fixed to be set on described saw tooth nut, described saw tooth nut and described saw tooth
Bolt, described saw tooth axially passes described worm gear case, and the upper end of described saw tooth is fixedly installed connecting seat, described
The lower end of connecting seat and described connecting rod is hinged.
Further, it is fixedly installed at least two keys on the outer circumference surface of described saw tooth nut, described worm gear
Inner surface setting has keyway, and described key is engaged correspondingly with described keyway.
Further, guide sleeve is fixedly installed in described worm gear case, described guide sleeve coaxial sleeve is in described saw
Coordinate on tooth and with described saw diastema.
Further, the lower end of described connecting seat and described connecting rod is hinged by bearing pin.
Compared with prior art, advantage of the present utility model is：
（1）, mould height adjustment amount it is larger, ensure connecting rod and saw tooth intensity on the premise of, its mould height adjustment amount can reach
800mm；
（2）, connecting rod punch crank drive under amplitude of fluctuation do not limited by mould height adjusting device；
（3）, processing it is simple；
（4）, saw tooth and saw tooth nut between lubrication can use thin oil lubricant, high lubricating effect.
