Detailed Description

In view of the above technical solutions, preferred embodiments are described in detail with reference to the drawings.

The utility model discloses a toper section of thick bamboo rolling frock, refer to fig. 1 to 3, including lower bed die 10, toper formpiston 20, go up left bed die 30, go up right bed die 40.

The lower female die 10 has a 180-degree conical barrel conical surface cavity formed on the upper surface thereof, and the 180-degree conical barrel conical surface cavity refers to a conical surface structure of a half conical barrel after the conical barrel is divided into two parts from a circle center position (an axis position). The upper left female die 30 and the upper right female die 40 are respectively provided with a conical surface cavity of a 90-degree conical cylinder, and the conical surface cavity of the 90-degree conical cylinder is a conical surface structure of a quarter of the conical cylinder. After the upper left female die 30 and the upper right female die 40 are closed, a cavity of the upper left female die forms a conical surface structure of a half conical cylinder; and after the lower female die, the upper left female die and the upper right female die are assembled, a conical cylinder structure cavity with the size of the outer diameter of the conical cylinder is formed.

The upper left female die 30 and the upper right female die 40 are respectively located on both sides of the upper end surface of the lower female die 10, and can be moved to and from a mold along the upper end surface of the lower female die 10 by an external force of the thrust device 70. The thrust device 70 may be various devices that can apply an external force, such as a jack, etc.

The conical male die 20 is in a conical cylinder shape, and the outer diameter dimension thereof is the inner diameter dimension of the conical cylinder. After the die is closed, the die is positioned in a conical cylinder structure cavity formed by the lower female die, the upper left female die and the upper right female die, the axis of the conical male die 20 is superposed with the axis of the conical cylinder structure cavity formed by the lower female die, the upper left female die and the upper right female die, and the axis of the conical male die 20 is positioned in a plane where contact surfaces of the lower female die, the upper left female die and the upper right female die are positioned.
