the reference numerals shown in fig. 1 to 2 are respectively expressed as: the method comprises the following steps of 1-supporting a base body, 2-installing a cavity, 3-air inlet valve seat, 4-air inlet valve, 5-elastic component, 6-sealing cavity, 7-air inlet pipe, 8-spring seat, 9-air inlet valve bush, 10-return spring and 11-clamping ring.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 to 2, a vacuum breaking device for a press machine includes a support base 1, an installation cavity 2 opened inside the support base 1, an air inlet valve seat 3 connected in the installation cavity 2 of the support base 1 in a matching manner, an air inlet valve 4 connected in the air inlet valve seat 3 in a matching manner, and an elastic component 5 arranged on the air inlet valve 4 in a matching manner, wherein a sealing cavity 6 communicated with the installation cavity 2 is arranged at an end portion of the support base 1 far from the air inlet valve seat 3, and an air inlet pipe 7 is connected to an end portion of the sealing cavity 6.
The air inlet valve seat 3 is connected to the support seat body 1 through a bolt, and through mutual matching of the air inlet valve 4, the elastic component 5 and the air inlet pipe 7, the damage of a vacuum layer at the joint of the material pressing head and the paste is effectively realized, so that when the valve core returns, the phenomenon of material adhesion cannot occur on the valve core, the purpose of breaking vacuum is effectively achieved, and the product yield is improved. In the working process, after the pressing head is extruded, the compressed air electromagnetic valve is powered on, after compressed air enters the sealed cavity 6, along with the increase of the area of the compressed air of the sealed cavity 6, when the compressed air is larger than the elastic force of the elastic component 5, the air inlet valve 4 is opened, the compressed air enters the vacuum layer at the joint of the pressing head and the paste and is damaged, and the pressing head is separated from the bonding surface of the paste. When the material pressing head returns, the compressed air electromagnetic valve is powered off, the air inlet valve 4 is closed, the material pressing head returns to the original position, one-time extrusion work is completed, and preparation is not made for the next extrusion.
