Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] like figure 1 and figure 2 As shown, a passive roller traction biaxially stretched tube continuous molding equipment includes a die body 1, a mandrel 2 is arranged inside the die body 1, and a gap 3 is reserved between the die body 1 and the mandrel 2 , the gap 3 is used for material circulation, and the gap 3 gradually becomes smaller along the forward direction of the material, which helps to gradually increase the extrusion force on the material, so that the material can be fully kneaded and mixed. A feed port 4 is provided, and the feed port 4 communicates with the gap 3, and the material is input into the gap 3 from the feed port 4; the die body 1 is a...

Abstract

The invention provides a passive rolling wheel traction type bidirectional stretching tube continuous forming device and method, and relates to the technical field of mechanical devices. The device comprises a die head body, a core rod is arranged in the die head body, a gap is reserved between the die head body and the core rod, the gap is gradually reduced in the advancing direction of a material, a feeding port is formed in the die head body, and the feeding port communicates with the gap; and a mouth die is further arranged on the die head body, a conical sleeve is arranged at the front end of the mouth die, the conical sleeve is connected with the mouth die, the front end of the conical sleeve is connected with a traction machine, a plurality of groups of rolling wheels are annularlyarranged in the conical sleeve, and a discharging channel for allowing a pipe blank to be discharged is formed between the rolling wheels and the inner wall of the conical sleeve. The device has the advantages of being simple in structure, convenient to operate and good in forming effect.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a passive roller traction type continuous forming equipment for biaxially stretched tubes. Background technique [0002] At present, the stretching orientation process of polymer materials is that the material is at a temperature between the glass transition temperature and the melting temperature, through certain flow field control and control of molding processing conditions (temperature, force, etc.) to make the polymer chain structure The distribution and distribution show a strengthening trend, and they are arranged preferentially along the direction of force. The process by which molecules change from disordered arrangement to ordered arrangement. Due to the orderly arrangement of the polymer chains, the material changes from isotropy to anisotropy, that is, the strength of the material along the molecular orientation direction increases greatly. Utilizing th...
