Description
Technical field
The utility model belongs to cup-shaped metal stamping equipment technical field, particularly relates to a kind of Pneumatic demould formula constant voltage punching cup mould.
Background technology
The cup-shaped punching press of metal is widely used, as commodity such as stainless steel cup, washbowls, various covers, shell etc. in commercial Application, in punching course, pressure is very crucial parameter, but inevitably metal produces drag to drift in deformation process, therefore cause in punching course pressure non-constant, this just causes the cup quality problems after punching press, simultaneously owing to pushing mutually with drift in flow of metal process in punching course, cause cup to be stuck on drift and be difficult to the demoulding, in practical operation, affect production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Pneumatic demould formula constant voltage punching cup mould, the constant voltage chamber of air cylinder structure is set with it at drift, the principle of application pneumatic system constant pressure, in punching course, can not cause stamping pressure to change because of the drag in flow of metal process, in jumper bar and constant voltage chamber, jet channel is set, the jet demoulding in the time that jumper bar is mentioned.
The utility model solves the technical scheme that its technical problem adopts: an a kind of Pneumatic demould formula constant voltage punching cup mould is provided, comprise cope match-plate pattern, lower bolster and drift, on described cope match-plate pattern, drift is housed, described lower bolster is provided with punching, the punching of described drift lower end aligned, described drift comprises constant voltage chamber and jumper bar, described jumper bar upper end is piston end, described piston end is arranged in constant voltage chamber and is air cylinder structure, described jumper bar slides up and down along constant voltage cavity axis, demoulding air flue is set in described jumper bar, wear-resisting pressure head is installed in described jumper bar lower end, described demoulding air flue one end opening is positioned at piston end sidewall, other end opening is positioned at wear-resisting pressure head lower end, buffer spring is installed in bottom, described constant voltage chamber, bottom, described constant voltage chamber is communicated with high-pressure air source with air inlet, described constant voltage chamber sidewall is interior with air flue, described air flue one end is communicated with air inlet, the other end arranges opening in constant voltage chamber madial wall, when described piston end moves to constant voltage chamber lower end, be positioned at air flue open communication on the demoulding air flue opening of piston end sidewall and constant voltage chamber madial wall.
Described constant voltage chamber lower port is equipped with end cap, between described end cap and jumper bar, linear bearing is installed.
Described jumper bar length is identical with the constant voltage chamber degree of depth.
Between described cope match-plate pattern and lower bolster, guide pillar is installed.
Beneficial effect
The utility model has the advantage of, the constant voltage chamber of air cylinder structure is set with it at drift, the principle of application pneumatic system constant pressure, in punching course, can not cause stamping pressure to change because of the drag in flow of metal process, in jumper bar and constant voltage chamber, jet channel is set, the jet demoulding in the time that jumper bar is mentioned.
