Abstract
The invention relates to a pneumatic demolding type constant-pressure cup punching mold, which comprises an upper template, a lower template and a punching head, wherein the punching head is arranged on the upper template and comprises a constant-pressure cavity and a punching rod, the upper end of the punching rod is a piston rod, the lower end of the punching rod is provided with a wear-resistance press head, the piston end is arranged in the constant-pressure cavity and is in an air cylinder structure, a demolding air passage is arranged in the punching rod, an opening formed at one end of the demolding air passage is positioned at the side wall of the piston end, an opening formed at the other end of the demolding air passage is positioned at the lower end of the wear-resistance press head, a buffer spring is arranged at the bottom of the constant-pressure cavity, the bottom is provided with an air inlet for being communicated with a high-pressure air source, an air passage is arranged in the side wall, one end of the air passage is communicated with the air inlet, the other end of the air passage is provided with an opening at the inner side wall of the constant-pressure cavity, and when the piston end moves to the lower end part of the constant-pressure cavity, the demolding air passage opening positioned at the side wall of the piston end is communicated with the air passage opening positioned on the inner side wall of the constant-pressure cavity. The constant-pressure cavity of the air cylinder structure is arranged on a punching head body, the punching pressure change caused by resistance force in the metal deformation process is avoided, air spraying passages are arranged in the punching rod and the constant-pressure cavity, and the air spraying demolding is carried out when the punching rod is lifted up.
Description
Technical field
The invention belongs to cup shaped metal pressing equipment technical field, particularly relate to a kind of Pneumatic demould formula constant voltage and rush 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 pressure in punching course non-constant, this just causes the cup quality problems after punching press, simultaneously owing to extruding 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 by this invention is to provide a kind of Pneumatic demould formula constant voltage and rushes cup mould, the constant voltage chamber of air cylinder structure is set with it at drift, the principle that application pneumatic system pressure is constant, stamping pressure will be caused to change because of the drag in flow of metal process in punching course, jet channel is set in jumper bar and constant voltage chamber, the jet demoulding when jumper bar is mentioned.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of Pneumatic demould formula constant voltage to rush cup mould, comprise cope match-plate pattern, lower bolster and drift, described cope match-plate pattern is equipped with drift, 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 in 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 open is positioned at piston end sidewall, other end opening is positioned at wear-resisting pressure head lower end, bottom described constant voltage chamber, buffer spring is installed, high-pressure air source is communicated with air inlet bottom described constant voltage chamber, with air flue in the sidewall of described constant voltage chamber, described air flue one end is communicated with air inlet, the other end arranges opening in constant voltage chamber inner sidewall, when described piston end moves to constant voltage chamber lower end, be positioned at demoulding airway open and the constant voltage chamber inner sidewall epithelium healing open communication of piston end sidewall.
Described constant voltage chamber lower port is equipped with end cap, installs linear bearing between described end cap and jumper bar.
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 invention has the advantages that, the constant voltage chamber of air cylinder structure is set with it at drift, the principle that application pneumatic system pressure is constant, stamping pressure will be caused to change because of the drag in flow of metal process in punching course, jet channel is set in jumper bar and constant voltage chamber, the jet demoulding when jumper bar is mentioned.
