Numerical-control pipe bending equipment and movable joint pressing block device for restraining bent pipe from becoming elliptic

The invention discloses numerical-control pipe bending equipment and a movable joint pressing block device for restraining a bent pipe from becoming elliptic. The movable joint pressing block device comprises a guide seat mounted on a rack and a plurality of movable joint pressing blocks, the movable joint pressing blocks are distributed side by side and installed on the guide seat in a sliding mode, and every two adjacent movable joint pressing blocks are hinged to each other; semicircular grooves are formed in the right end surfaces of the movable joint pressing blocks, and the semicircular grooves in the movable joint pressing blocks are matched to form a first semicircular groove. According to the technical scheme, the outer side wall of the bent part of a catheter can be sufficiently supported, so that the ellipticity of the bent part of the catheter is further reduced, and the outer side wall of the bent part of the catheter can be effectively prevented from being stretched and fractured. 本发明公开了一种数控弯管设备
