Abstract
The present invention relates to a kind of Constant pressure type cup punching die, including cope plate, lower template and drift, drift is housed on the cope plate, the lower template is provided with punching, the drift lower end aligned punching, the drift includes constant pressure chamber and jumper bar, the jumper bar upper end is piston end, it is in air cylinder structure that the piston end, which is arranged on constant pressure intracavitary, the jumper bar is slided up and down along constant pressure cavity axis, linear bearing is installed, buffer spring is installed in constant pressure bottom of chamber portion, and constant pressure bottom of chamber portion connects high-pressure air source with air inlet between the constant pressure chamber lower port and jumper bar.The constant pressure chamber of air cylinder structure is set with drift, using the principle that pneumatic system pressure is constant, because of the drag during flow of metal stamping pressure will not be caused to change in punching course, it is ensured that cup quality.
Description
Technical field
The invention belongs to cup shaped metal pressing equipment technical field, more particularly to a kind of Constant pressure type cup punching die.
Background technology
The cup punching press of metal is widely used, such as stainless steel cup, washbowl commodity, various covers in commercial Application,
Shell etc., pressure is very crucial parameter in punching course, but inevitably metal is produced in deformation process to drift
Raw drag, therefore cause pressure in punching course non-constant, this results in the cup quality problems after punching press.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of Constant pressure type cup punching die, and air cylinder structure is set with drift
Constant pressure chamber, will not be because of the drag during flow of metal in punching course using the principle that pneumatic system pressure is constant
Stamping pressure is caused to change, it is ensured that cup quality.
The technical solution adopted for the present invention to solve the technical problems is：A kind of Constant pressure type cup punching die is provided, including cope plate,
On lower template and drift, the cope plate be equipped with drift, the lower template be provided with punching, the drift lower end aligned punching,
The drift includes constant pressure chamber and jumper bar, and the jumper bar upper end is piston end, and it is in cylinder that the piston end, which is arranged on constant pressure intracavitary,
Structure, the jumper bar is slided up and down along constant pressure cavity axis, installs linear bearing between the constant pressure chamber lower port and jumper bar, institute
State constant pressure bottom of chamber portion and buffer spring is installed, constant pressure bottom of chamber portion connects high-pressure air source with air inlet.
The jumper bar length is identical with constant pressure chamber depth.
Guide pillar is installed between the cope plate and lower template.
Beneficial effect
It is an advantage of the current invention that the constant pressure chamber of air cylinder structure is set with drift, using the original that pneumatic system pressure is constant
Reason, will not cause stamping pressure to change, it is ensured that cup matter in punching course because of the drag during flow of metal
Amount.
Brief description of the drawings
Fig. 1 is ram piston end of the present invention and constant pressure chamber mounting portion structural representation.
Fig. 2 is schematic structural view of the invention.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments be merely to illustrate the present invention and
It is not used in limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As illustrated in fig. 1 and 2, a kind of Constant pressure type cup punching die, including cope plate 1, lower template 2 and drift 3, it is described on
Drift 3 is housed, the lower template 2 is provided with punching, the lower end aligned punching of drift 3, the drift 3 in template 1
Including constant pressure chamber 4 and jumper bar 5, the upper end of jumper bar 5 is piston end 6, and the piston end 6, which is arranged in constant pressure chamber 4, is in
Air cylinder structure, the jumper bar 5 is slided up and down along the axis of constant pressure chamber 4, is installed between the lower port of constant pressure chamber 4 and jumper bar 5
Buffer spring 8 is installed in linear bearing 7, the bottom of constant pressure chamber 4, and the bottom of constant pressure chamber 4 connects height with air inlet 10
Pressurized air source.
The length of jumper bar 5 is identical with the depth of constant pressure chamber 4.
Guide pillar 9 is installed between the cope plate 1 and lower template 2.
In actual motion, cope plate 1 and lower template 2 are closed up first, and drift 3 is controlled whole in cope plate by pressing equipment
The downward stamped metal blank of body, the inner air pressure of constant pressure chamber 4 is setting stamping pressure, and drift and blank are mutual in punching course
Phase separation and make blank deformation, now blank is extruded mutually with drift, as metal stock distortional stress constantly changes,
The elastic force of metal stock reacts on drift, and when drift stress is more than constant pressure 4 inner air pressure of chamber, jumper bar 5 is retracted perseverance
Press chamber 4 in, the stamping press suffered by metal stock is identical with the inner air pressure of constant pressure chamber 4 in the case, and with jumper bar 5 with
And the overhang of drift 3 is completely irrelevant, it is ensured that metal stock suffered stamping press in deformation overshoot is constant.
