[0019] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. The following embodiments can enable those skilled in the art to understand the present utility model more comprehensively, but do not limit the present utility model within the scope of the embodiments.

[0020] As Figure 1 and Figure 2 shown, the following technical solution is adopted in this specific embodiment: It includes a rotating seat 1. The rotating seat 1 is of a cylindrical structure. A cylindrical protrusion 2 is provided on the top of the rotating seat 1. The protrusion 2 is located at the middle position of the rotating seat 1. The rotating seat 1 and the protrusion 2 are integrally provided, and the protrusion 2 coincides with the central axis of the rotating seat 1.

[0021] The rotating base 1 is provided with a rotating hole 3 and two locking holes 4. One rotating hole 3 and two locking holes 4 are both arranged outside the protrusion 2, and one rotating hole 3 and two locking holes 4 are evenly distributed on a circular ring. The circular ring is concentric with the rotating base 1. A rotating shaft is fitted in the rotating hole 3, and the rotating base 1 is connected to the stamping mechanism through the rotating shaft. The stamping mechanism is not shown in the figure. The structure and principle of the stamping mechanism

[0022] are both mature existing technologies and will not be elaborated here. A locking bolt is fitted in the locking hole 4, and the rotating base 1 is fixed to the stamping mechanism through the locking bolt. When stamping, the rotating base 1 is fixed to the stamping mechanism. After stamping, the rotating base can be rotated to take out the blank of the shoe.

[0023] A placing groove 5 is provided at the center of the rotating base 1 and the protrusion 2. The placing groove 5 is of a stepped structure, with the diameter of the upper part of the placing groove 5 larger than that of the lower part. A through hole 6 communicates with the bottom of the placing groove 5. The diameter of the through hole 6 is smaller than that of the lower part of the placing groove 5. The bottom of the through hole 6 communicates with an empty groove 7. The diameter of the empty groove 7 is larger than that of the through hole 6. The copper cylindrical material after intermediate frequency heating is placed in the placing groove 5 for stamping. A stop block 8 is fitted in the placing groove 5. The stop block 8 is of a T-shaped structure. The lower part of the stop block 8 is arranged in the placing groove 5, and the upper part of the stop block 8 is placed on the top of the protrusion 2 and is connected and fixed to the protrusion 2 through a bolt. The through hole 6 and the empty groove 7 are arranged in cooperation with the reset ejector rod 9 of the stamping mechanism. After stamping, the blank of the shoe 10 is ejected through the reset ejector rod 9 to complete the material taking.

[0024] Working principle: The rotating base 1 is connected and fixed to the stamping mechanism by passing a bolt through the locking hole 4. The copper cylindrical material after intermediate frequency heating is placed in the placing groove 5 of the tooling. After being blocked by the stop block 8, the stamping rod of the stamping mechanism passes through the empty groove 7 and the through hole 6 to stamp the cylindrical material. After stamping, the fixation between the rotating base 1 and the stamping mechanism is released, and the rotating base 1 is rotated so that the positions of the empty groove 7 and the through hole 6 correspond to the reset ejector rod 9 of the stamping mechanism. Then, the stop block 8 is removed, and the stamped cylindrical material is ejected through the reset ejector rod 9 of the stamping mechanism to obtain the blank of the shoe 10. The solid cylindrical material can be pre-cast in the state of the shoe product, avoiding the problems of large material waste and low machining efficiency caused by machining. The process is shortened, the production efficiency is improved, and there is no need to clean the chips after machining, reducing the labor intensity and production cost.

[0025] Such as Figure 3As shown, the structure of this Embodiment 2 is the same as that of Embodiment 1 in other aspects, except that: the stopper 8 is completely disposed within the placement groove 5. The stopper 8 is connected to the driving rod of the driving cylinder 11. The driving cylinder 11 is disposed inside the protrusion 2 and is mounted on the side of the placement groove 5. A moving groove for the translation of the stopper 8 is communicated with the side of the placement groove 5. The stopper 8 is driven to translate by the driving cylinder 11 to achieve shielding and removal. When shielding is required before stamping, the driving cylinder 11 drives the stopper 8 to move into the placement groove 5 to shield the cylindrical material. After the stamping is completed, the driving cylinder 11 drives the stopper 8 to move into the moving groove to release the shielding of the cylindrical material, facilitating subsequent discharging operations.
