Abstract
The utility model discloses a core which comprises a core head and a core tube and is characterized in that the bottom of the core tube is in a shovel shape; and the core head is integrally formed with the core tube. In a processing technology of a polytetrafluoroethylene pipe, the shovel-shaped core tube provided by the utility model can draw the polytetrafluoroethylene pipe longitudinally or transversely, and the shortcomings of the prior art are overcome.
Description
Technical field
The utility model relates to the device in a kind of polytetrafluoroethylene (PTFE) pipe fitting drawing process, relates in particular to a kind of core.
Background technology
Core is needed device in the polytetrafluoroethyltubing tubing drawing process.In the production process of polytetrafluoroethylene (PTFE), core need to bear larger pressure, and therefore when determining the core size, it is not damaged to need consideration, and this just needs certain diameter and length.The core pipe afterbody of core is cylindrical shape in the prior art, and cross-sectional area is little, can only carry out longitudinal stretching, can not carry out cross directional stretch to polytetrafluoroethyltubing tubing, thereby can't satisfy the existing needs of producing.
The utility model content
The utility model technical issues that need to address provide core a kind of applied widely, easy to use and simple in structure.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of core includes core bedding frame and core pipe, it is characterized in that: the bottom of described core pipe is spade.
Further, described core bedding frame and core pipe are one-body molded.
Compared with prior art, spade is arranged to from simple round tube shape in core pipe of the present utility model bottom, and in the production technology of polytetrafluoroethylene (PTFE), the core pipe of spade can not only stretch longitudinally to polytetrafluoroethyltubing tubing, also can carry out cross directional stretch to it, satisfy the demand.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the utility model relates to a kind of core, and it includes core bedding frame 1 and core pipe 2, and the afterbody of core pipe 2 is set to spade; Core bedding frame 1 is one-body molded with core pipe 2.In the processing technology of polytetrafluoroethyltubing tubing, the core pipe of the utility model spade can not only stretch longitudinally to polytetrafluoroethyltubing tubing, also can carry out cross directional stretch to it, has remedied the defective of prior art.
Claims (2)
1. a core includes core bedding frame and core pipe, it is characterized in that: the bottom of described core pipe is spade.
2. a kind of core according to claim 1, it is characterized in that: described core bedding frame and core pipe are one-body molded.
