Abstract
The utility model relates to a tension heat shaping roller return pipe fixing device, which comprises a rotating connection rear flange (1), a return water pipe (2), a flange (3) and bolts (4), and is characterized in that the tail end of the return water pipe (2) is provided with an external deflection, the inner wall of the flange (3) is provided with an internal deflection, and the external deflection is matched with the internal deflection; and the flange (3) is arranged outside the return water pipe (2), and the flange (3) is fixedly connected with the rotating connection rear flange (1) through the bolts (4). The utility model has the beneficial effects that: 1, the rotation is prevented, through arranging the external deflection on the return water pipe to match with the internal deflection of the flange, the flange is fixed on the rotating connection rear flange through a fixed bolt, so the shift of the return water pipe caused by rotation is solved; 2, the axial vibration is prevented, external thread is machined on the tail end of the return water pipe, with a thick lock nut and an elastic washer, the axial vibration caused by the loosing of the return water pipe is avoided. The utility model solves the problem of the shift of the return water pipe, improves the stability of the product quality, has long service life and low operating cost.
Description
(1) technical field
The utility model relates to a kind of nervous HEAT SETTING roller return pipe fixture, is mainly used in the production process of chemical fibre.
(2) background technology
In the chemical fibre production process; tow regular meeting in nervous HEAT SETTING process causes product quality influenced because setting temperature is not enough; and in Niu Mage equipment; guaranteeing under the supply gas pressure prerequisite; hydrophobic effect is directly to influence roll surface temperature in the roller; so that influence typing effect; in this equipment; the syndeton of return pipe 2 and swivel coupling rear flange 1 is referring to Fig. 1 and Fig. 2; its return pipe 2 outer walls are provided with flange 3; be equipped with clamp 5 between return pipe 2 and the flange 3, flange 3 is fixedlyed connected with swivel coupling rear flange 1 by bolt 4.This syndeton is in operation, can be loosening between return pipe 2 and the flange 3, and produce rotation displacement relatively earlier, and cause axial motion easily.Thereby because of solid failure, and cause return pipe siphon displacement, cause condensed water to dredge away, directly influence roll surface temperature, also cause the wearing and tearing of clamping device and return pipe, life cycle is short, the operating cost height.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of nervous HEAT SETTING roller return pipe fixture is provided, and has solved return pipe displacement problem, improved the stability of product quality, and life cycle is long, and operating cost is low.
The purpose of this utility model is achieved in that a kind of nervous HEAT SETTING roller return pipe fixture, it comprises swivel coupling rear flange, return pipe, flange and bolt, it is characterized in that: the terminal outer wall of described return pipe is provided with outer flat position, flat position in described flange inner wall is provided with, match with described interior flat position in described outer flat position; Described flange is arranged at outside the described return pipe, and described flange is fixedlyed connected with the swivel coupling rear flange by bolt.
Described return pipe end also is provided with external screw thread, and described external screw thread is provided with the locking high nut, and described locking high nut is arranged at the side of described flange away from the swivel coupling rear flange, is provided with elastic washer between described locking high nut and the described flange.
Compared with prior art, the beneficial effects of the utility model are:
The one, anti-rotation, by flat position outside the processing on return pipe, cooperate with flat position in the flange, flange is fixed on the swivel coupling rear flange by set bolt, solves return pipe rotation displacement problem.
The 2nd, anti-axial motion at the terminal threading of return pipe, is equipped with locking high nut and elastic washer, and is loosening and cause axial motion to solve return pipe.
This covering device has solved return pipe displacement problem, and the stability and the life cycle that have improved product quality greatly are long, and operating cost is low.

(5) specific embodiment
Referring to Fig. 3-4, a kind of nervous HEAT SETTING roller return pipe fixture that the utility model relates to mainly is made up of swivel coupling rear flange 1, return pipe 2, flange 3 and bolt 4;
Described return pipe 2 terminal outer walls are provided with outer flat, flat position in described flange 3 inwalls are provided with, and match with described interior flat position in described outer flat position;
Described flange 3 is arranged at outside the described return pipe 2, and described flange 3 is fixedlyed connected with swivel coupling rear flange 1 by bolt 4;
Described return pipe 2 ends also are provided with external screw thread, described external screw thread is provided with locking high nut 7, described locking high nut 7 is arranged at the side of described flange 3 away from swivel coupling rear flange 1, is provided with elastic washer 6 between described locking high nut 7 and the described flange 3.
