Description

Stamping die with replaceable stamping head Technical Field The utility model relates to the technical field of stamping dies, in particular to a stamping die with a replaceable stamping head. Background Currently, in the related field of pharmaceutical manufacturing, most tablet presses on the market carry a tablet press die to perform rotational movement to produce tablets. In this process, the tablet press die moves up and down along the guide rail of the tablet press to complete the compression process. Key factors affecting the production efficiency of the tablet press include not only the rotational speed of the punch disc itself, but also the dies carried by the punch disc during each revolution. Notably, the mold, as a consumable, requires periodic replacement during use. The punch in the traditional die structure is usually of a fixed design, and when the punch is worn or the punch with different shapes needs to be replaced, the die needs to be integrally disassembled, so that the replacement efficiency is low, and the maintenance cost is high. Disclosure of utility model The present utility model is directed to a die with replaceable punches to solve the above-mentioned problems. In order to achieve the purpose, the utility model provides a die with a replaceable punch, which is characterized by comprising the following components: The middle die is provided with an upper punch and a lower punch at two sides respectively; The upper punch comprises an upper punch body and an upper punch rod connected with the upper punch body, one end of the upper punch body is contacted with an upper pinch roller of a first tablet press through the upper punch rod, and the other end of the upper punch body is connected with the middle die; the lower punch comprises a lower punch body and a lower punch rod connected with the lower punch body, one end of the lower punch body is in contact with an upper pressing wheel of the second tablet press through the lower punch rod, and the other end of the lower punch body is connected with the middle die. Further, the upper punch further comprises an upper fixing pin and an upper punch pin, the upper punch main body is connected with the upper punch rod through the upper fixing pin, and the upper punch pin is connected with the upper punch main body and the middle die. Further, the lower punch further comprises a lower fixing pin and a lower punch pin, the lower punch main body is connected with the lower punch rod through the lower fixing pin, and the lower punch pin is connected with the lower punch main body and the middle die. Further, the upper pinch roller of the first tablet press and the upper punch are arranged on two sides of the middle die in mirror image opposition with the lower punch and the upper pinch roller of the second tablet press. Further, the sizes of the pressing wheel on the first tablet press and the pressing wheel on the second tablet press are consistent. Further, an upper punch cap for connecting the upper punch pin to the upper punch body is arranged on the outer side of the upper punch pin. Further, the upper punch further comprises a guide key, and the guide key is used for plugging the upper fixing pin. Further, the guide key is slidably connected to the upper punch body, and the guide key is slidably connected to the outer side of the upper fixing pin. Further, an undershoot cap for connecting the undershoot nail to the undershoot head main body is arranged on the outer side of the undershoot nail. Further, the end face of the upper punch body and/or the lower punch body, which is far away from the middle die, is arc-shaped. Compared with the prior art, the utility model has the beneficial effects that: The stamping die with the replaceable stamping head realizes rapid replacement of the stamping head through the modularized design of the fixing pin, the stamping nail and the guide key, reduces the downtime, ensures uniform stress in the stamping process due to the mirror symmetry of the layout and the consistency of the dimension of the pressing wheels, improves the quality of finished products, enhances the connection stability of the stamping head and the middle die and reduces the maintenance cost due to the addition of the stamping cap and the guide key.
