Description
Technical field
The present invention relates to leaf springs of car production technical field, be specifically related to a kind of leaf spring end corner cut and squeeze limit composite die.
Background technology
Plate spring sheet needs corner cut in the course of processing, and after corner cut, leaf spring end needs via after-treatment to reaching after requirement width
Meet regulation of dispatching from the factory.Because leaf spring material hardness is very big, no matter it is that the leaf spring end portion width after corner cut or corner cut processes, all needs
Heat and just can carry out.In existing leaf spring production technology, first heating leaf spring end, then by corner cut station to leaf spring end
Carry out corner cut；After corner cut completes, by polishing apparatus, is polished in leaf spring end so that it is width reaches requirement of dispatching from the factory.Above-mentioned
The subject matter that mode exists is: one, production efficiency is low, power consumption height；Two, hand labor intensity is big, produces precision low；
Three, energy waste is serious；Four, leaf spring Repeat-heating, affects product quality.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to: provide a kind of leaf spring end corner cut to squeeze limit composite die, structure
Compact, leaf spring end can be carried out corner cut and crowded limit, improve work efficiency, reduce hand labor intensity, save the energy, improve
Product quality.
The present invention solves that the technical scheme that its technical problem is used is:
Leaf spring end corner cut squeezes limit composite die, including cope match-plate pattern and lower bolster, described cope match-plate pattern is arranged corner cutter and upper squeeze
Limit block, in lower bolster correspondence respectively, corner cutter and upper crowded limit block arrange undercut angles cutter and lower crowded limit block, and undercut angles cutter is fixed on incision
On the tool rest of angle, lower bolster two ends correspondence undercut angles tool rest and lower crowded limit block are respectively provided with corner cut position-limit mechanism and crowded limit position-limit mechanism.
This upper mould plate is fixed on punch press top shoe by upper die shank, during use, the leaf spring after heating is placed on undercut angles
On cutter, and being fixed to corner cut position by corner cut position-limit mechanism auxiliary leaf spring, then punch press top shoe drives cope match-plate pattern to move down, logical
Crossing the relative motion cutting leaf spring end of upper and lower corner cutter, after having cut, upper corner cutter resets, by operator by after corner cut
Leaf spring is transferred to squeeze on the station of limit, and by crowded limit position-limit mechanism auxiliary fixing plate spring, fixes rear punch press top shoe and again drive
Template moves down, and extrudes leaf spring end by upper crowded limit block so that it is width reaches size of dispatching from the factory, punch press top shoe stroke root when squeezing limit
