Abstract

The invention discloses an edge rolling spinning pneumatic boosting system for coin making. The edge rolling spinning pneumatic boosting system comprises a machine body, a center disc and a check ring are arranged on the machine body, the center disc is connected with a corresponding rotation driving device, a plain edge gauge is arranged on the periphery of the center disc, a molding channel for spinning machining of a coin blank cake is formed between the center disc and the plain edge gauge, a cake conveying rotary disc is arranged at the bottom of the check ring, and a coin storage groove is jointly formed by the check ring and the cake conveying rotary disc. The cake conveying rotary disc is connected with a corresponding rotation driving device, a cake conveying outlet is formed in the lateral face of the check ring and communicated with the molding channel through a cake conveying sliding way, pneumatic spraying nozzles are formed at the cake conveying outlet of the check ring and the interior of the cake conveying sliding way and communicated with air sources through corresponding pipes, and the air spraying direction of the pneumatic spraying nozzles is coincident with the movement direction of the coin blank cake. By means of the edge rolling spinning pneumatic boosting system, two-section type dual boosting is carried out at the position of the cake conveying outlet and the position of the cake conveying sliding way, so that the edge rolling efficiency is improved by more than two times, and the edge rolling speed is stable.

Description

technical field [0001] The invention belongs to the technical field of coinage, and in particular relates to an edge spinning pneumatic booster system for coinage. Background technique [0002] Metal spinning technology is an emerging field in modern metal pressure processing. It is a process method that uses the plasticity of metal to form various hollow rotating bodies and rolling flanges, and is a processing method with less cutting and no cutting. At present, it is widely used in metal pressure processing and machinery manufacturing departments. It is mainly used in the defense industry such as high-precision missile heads, cone covers, cone covers, parts of the aviation industry and civilian aluminum pots. However, due to the characteristics of processing parts one by one, the processing efficiency is low. Especially in the production of ordinary circulation coins, factors such as lubricating fluid and slideway friction will affect the efficiency of spinning processi...
