Compared with the prior art, the utility model discloses descend at the formpiston, the in-process of the bed die impresses, the formpiston can push down the apron, make the apron, connecting rod and piston move down, and then impress the air in the cavity in the gas tank (the check valve is in the state of opening), the air is discharged from the outlet duct again in the storage tank, thus, most air can rush into the top of bed die, and under the guide effect of apron, produce the motion trend of horizontal direction, and then realize sweeping to the bed die surface, effectively clear away the diamond powder at bed die top, it is reliable to have prevented to produce between diamond powder and the formpiston, ensure that the shaping is effectual.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a female die; 2. a male mold; 3. a containing groove; 4. a cavity; 5. a piston; 6. a connecting rod; 7. a cover plate; 8. a gas tank; 9. an air outlet pipe; 10. an air inlet pipe; 11. a one-way valve; 12. a spring.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, the double-channel roller press forming die comprises a female die 1 and a male die 2, wherein the male die 2 is positioned above the female die 1, one side of the top of the female die 1 is provided with an accommodating groove 3 and a cavity 4 which are communicated with each other, the cavity 4 is cylindrical, a piston 5 is arranged in the cavity 4 in a matching manner, the top of the piston 5 is provided with a connecting rod 6 and a cover plate 7, and the cover plate 7 is arranged in the accommodating groove 3 in a matching manner;
an air box 8 is arranged outside the female die 1, an air outlet pipe 9 is arranged at the upper part of the outer wall of the air box 8, an air inlet pipe 10 is arranged at the lower part of the outer wall, the air inlet pipe 10 is communicated with the bottom of the cavity 4, and the air outlet pipe 9 is communicated with the accommodating groove 3;
and the air outlet pipe 9 is provided with a one-way valve 11. Initially, the cover plate 7 is located above the accommodating groove 3, when the male die 2 descends and is pressed into the female die 1, the male die 2 presses down the cover plate 7, the connecting rod 6 and the piston 5 move downwards, air in the cavity 4 is further pressed into the air box 8 (the one-way valve 11 is in an open state), and the air is discharged into the accommodating groove 3 from the air outlet pipe 9, so that most of the air can be flushed into the upper part of the female die 1 and generates a movement trend in the horizontal direction under the guiding action of the cover plate 7, so that the surface of the female die 1 is purged, the diamond powder at the top of the female die 1 is effectively removed, reliability between the diamond powder and the male die 2 is prevented, and a good forming effect is ensured.
One end of the connecting rod 6 is fixedly connected with the bottom of the cover plate 7, and the other end of the connecting rod 6 is fixedly connected with the top of the piston 5. Therefore, the cover plate 7, the connecting rod 6 and the piston 5 are reliably connected, the overall strength is improved, the cover plate 7 can be pressed and the overall movement can be driven by the descending of the male die 2, and the air flows and the air pressure in the air box 8 rises.
The sum of the length of the connecting rod 6 and the thickness of the piston 5 is greater than or equal to the depth of the cavity 4. That is, after the cover plate 7 completely enters the accommodating groove 3, the piston 5 just or not yet touches the bottom of the cavity 4, thereby ensuring that the top of the cover plate 7 is aligned with the notch of the accommodating groove 3, so that the cover plate 7 is integrated with the female mold 1.
The outer wall of the cover plate 7 is attached to the inner wall of the accommodating groove 3, and the thickness of the cover plate 7 is equal to the depth of the accommodating groove 3.
The height of one side of the air outlet pipe 9 communicated with the air box 8 is lower than that of one side of the air outlet pipe 9 communicated with the accommodating groove 3. Thus, the air can overflow to the upper part of the containing groove 3 to the maximum extent after being discharged from the air outlet pipe 9, and the purging effect on the diamond powder is further ensured.
A spring 12 is arranged between the bottom of the piston 5 and the bottom of the cavity 4. Through the effect of spring 12, be convenient for apron 7 to reset to the top of storage tank 3.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
