Title:
NON-METAL COMPOSITE PIPE FLARING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/217727
Kind Code:
A1
Abstract:
A non-metal composite pipe flaring device, relating to the technical field of plastic pipe manufacturing devices. The non-metal composite pipe flaring device comprises a device chassis (8); a clamping mechanism used for clamping a composite pipe, a driving structure, and a flaring structure are arranged at the upper portion of the device chassis (8); the clamping mechanism is arranged corresponding to the flaring structure; and the driving structure drives the flaring structure to perform a flaring operation on the composite pipe (1) mounted on the clamping mechanism. Flaring dies (9) are driven by means of arc-shaped grooves (1201) on a large gear (12) to move in the radial direction, and a servo motor (18) is used to drive the large gear (12), and therefore, the forward rotation and backward rotation of the large gear (12) are controlled, i.e., the inward shrinkage and flaring of the flaring dies (9) are automatically adjusted. In the flaring mode, the flaring of the pipe is achieved by means of the radial outward flaring of eight flaring dies (9), and therefore, the present invention avoids that the pipe is damaged due to the fact that an inner layer is extruded when the composite pipe (1) is flared in an existing flaring mode.
