The number of the punches is plural.

The beneficial effect of the present invention is that: through the above-mentioned structural arrangement, at least two punches are arranged on the turntable along the rotation direction of the turntable. Specifically, the two punches may be different. When in use, the required punch is delivered to the punch station through the turntable, so that the punch can punch and shape the end of the pipe fitting on the clamping station. When different punches need to be used, the corresponding punches can be switched to the punching station through the rotation of the turntable, so that the punches can shape and punch the ends of the pipe fittings on the clamping station. In the rotary die changing device of the pipe end machine of the present invention, through the setting of the turntable, the rotation switching of each punch is realized, so as to meet the stamping needs of different pipe fittings, the operation is simple, the use is convenient, the production efficiency is effectively improved, and the Mass production of various types of pipe fittings.

Detailed ways

Below, in conjunction with accompanying drawing and specific embodiment, the present invention is further described:

1 to 3 , a rotary die changing device for a pipe end machine includes a turntable 1 , a punch station 2 and a clamping station 3 . On the turntable 1 and along the rotation direction of the turntable 1 , at least There are two punches 4, and the turntable 1 is used to rotate the punches 4 to convey the punches 4 to the punch station 2, and the clamping station 3 is arranged in the punching direction of the punch station 2. At the front end, the clamping station 3 is used for clamping the pipe 9 so that the punch 4 of the punch station 2 punches the end of the pipe. Wherein, the turntable can be driven to rotate by a servo motor; the number of punches 4 can be multiple, specifically, it can be six or eight. Of course, other quantities are also possible; the pipe fittings can be copper pipes and other pipe fittings.

Through the above-mentioned structural arrangement, at least two punches are arranged on the turntable along the rotation direction of the turntable. Specifically, the two punches may be different. When in use, the required punch is delivered to the punch station through the turntable, so that the punch can punch and shape the end of the pipe fitting on the clamping station. When different punches need to be used, the corresponding punches can be switched to the punching station through the rotation of the turntable, so that the punches can shape and punch the ends of the pipe fittings on the clamping station. In the rotary die changing device of the pipe end machine of the present invention, through the setting of the turntable, the rotation switching of each punch is realized, so as to meet the stamping needs of different pipe fittings, the operation is simple, the use is convenient, the production efficiency is effectively improved, and the Mass production of various types of pipe fittings.
