Spring is connected between the end lower surface of telescopic rod and the vertical slide rail bottom end.
The ejector retainner plate upper surface is provided with the connector for being connected with the swing rod bottom end, and fixed pin passes through the company
Both ends fasten after corresponding through-hole on fitting and swing rod, and the outer diameter of the fixed pin is less than the internal diameter of the through-hole；The male model
The slide cartridge convenient for Rolldown hem pushing block upward and downward movement is provided in plate, the width of the slide cartridge is greater than the Rolldown hem pushing block
Width.
First telescopic rod, the second telescopic rod and third telescopic rod are electric telescopic rod.
The flat shell is hard metal shell.
The elastic element includes spring.
The circular shaft is connected with rotating electric machine.
Application method of the invention are as follows:
1, mold is opened, and is respectively put into flat shell in the two sides for the side that lower convexity and upper protrusion are combined into, then
Guan Mo；
2, the non-bead portion of flat shell is pushed down in briquetting movement, and circular shaft is close and contacts the crimping of flat shell
End, then proceedes to move in the second groove, and the tilting on one side of flat shell is simultaneously located in third groove, and then Rolldown hem pushes away
Block moves upwards until being in close contact with circular shaft, the tilting side of flat shell is located in the 4th groove at this time, upper crimping pushing block
Until being in close contact with circular shaft, the second groove, third groove and the 4th groove group are combined into cylinder type at this time, approach for movement inwardly
The seamlessly flat shell exterior of outsourcing cans, and circular shaft is then close to the flat shell for being seamlessly located at cans
Crimping is completed in inside.
3, Rolldown hem pushing block moves downward, and briquetting and upper crimping pushing block are moved outward to leave flat shell, circle
Axis is slided on horizontal slide rail to be detached from inside crimping, and circular shaft rotates under the drive of rotating electric machine, conducive to circular shaft is taken off quickly
Inside crimping, then it is opened, it is primary to take out the molding flat shell of two crimpings.

Made of the two sides of side can place flat shell, i.e. double-station, make two flat shells of time processing cans,
Duration shortens half, high production efficiency, and production cost substantially reduces；Circular shaft, the second groove, Rolldown hem pushing block and upper crimping pushing block
Combination settings, circular shaft is located inside crimping, is located at outside crimping after the second groove, Rolldown hem pushing block and the combination of upper crimping pushing block
Portion exerts a force together, guarantee crimping it is inside and outside be circle, without the defects of collapsing, ratio of briquetting is high, high production efficiency；Swing rod is set
Set, make Rolldown hem pushing block can control to do fine tuning movement, the setting of vertical slide rail and spring, make crimping pushing block can upward and downward do
Fine tuning movement, convenient for the second groove, Rolldown hem pushing block and upper crimping pushing block, accurately group is combined into cylindrical shape；The end of second telescopic rod
The setting that end is slidably connected with the horizontal slide rail being located on the male template side wall, enables circular shaft to detach crimping after molding；
The setting of rotating electric machine, makes circular shaft unhinderedly, rapidly detaches crimping after molding, additionally it is possible to rise in circular shaft rotary course
To the effect of polishing crimping inner wall, further make the smoothness of crimping more preferable, circularity is higher.Cooperate between each component of the present invention and closes
Reason, precision cooperation, realizes the double-station flange crimping operation of the high circularity of computer casing.
