Abstract
The invention discloses an engine exhaust pipeline connector device and a production method thereof. The engine exhaust pipeline connector device comprises a carbon fiber tube and a joint. The production method comprises the following steps: reaming one end of the carbon fiber tube, and performing folding and insertion weaving; inserting the thickened end of the carbon fiber tube from the small-caliber end of the joint, thickening the end of the carbon fiber tube, uniformly distributing the thickened carbon fiber tube in a casting cup, and casting the carbon fiber tube in the casting cup to cast the end of the carbon fiber tube with the joint; solidifying the cast part in a natural manner or a heating manner; pre-tensioning the cast joint and the thickened part to uniformly stress fibers of the thickened part so as to improve the entire breaking tension. Compared with the prior art, the engine exhaust pipeline connector device has the advantages that the problem of casting strength of a soft rigging and the like is solved; particularly, the effect on a high-strength fiber rope, such as a fiber rope made from aramid, a fiber rope made from an ultra high molecular weight polyethylene material and a fiber rope made from a PBO (poly-p-phenylenebenzobisthiazole) material, is obvious.

Technical field
The present invention relates to a kind of engine exhaust pipeline interface arrangement and production method thereof, belong to exhaust pipe of engine technology for making field.
Background technology
Waste pipe needs noise reduction process, so interface position is higher to the performance requirement of material, structure.
Summary of the invention
In order to make joint casting and cordage have equal strength design, improve fiber utilization rate, to promote the application of fiber casting rigging, the invention provides a kind of pipe interface device.
Object of the present invention is carried out specific implementation by the following technical programs:
Engine exhaust pipeline interface arrangement, comprises carbon fiber pipe and joint, by the reaming of carbon fiber pipe one end, gets 1/3 left and right, is folded and spliced, and then pre-stretch-draw, increases cable body end portion diameter thick;
The link of described joint has taper hole, large 2 to 3 millimeters of carbon fiber pipe end diameter after described joint selects taper hole small-caliber end than overstriking, taper hole length is 3-5 times of the carbon fiber pipe end diameter after overstriking, tapering is got 12-15 degree, then, the carbon fiber pipe end after overstriking is penetrated from the small-caliber end of joint, again the end of carbon fiber pipe is increased thick, fiber is dispersed in the pouring cup of joint inside, and keeps carbon fiber pipe and taper hole coaxial
Then carbon fiber pipe is increased and is slightly evenly distributed in pouring cup, and the carbon fiber pipe in pouring cup is cast, the end of carbon fiber pipe and joint are cast on together, the resinae adhesive that cast material selection intensity is high;
Then casting position is carried out natural consolidation or added hot consolidation;
Finally, to Casting Joint and the pre-stretch-draw of thickened portion, make the fiber of thickened portion stressed evenly, to improve overall rupture pull force.
The production method of engine exhaust pipeline interface arrangement, adopts one end of carbon steel pipe to be spliced the direct overstriking of method;
The link of described joint has taper hole, large 2 to 3 millimeters of carbon steel pipe end diameter after described joint selects taper hole small-caliber end than overstriking, taper hole length is 3-5 times of the carbon steel pipe end diameter after overstriking, tapering is got 12-15 degree, then, the carbon steel pipe end after overstriking is penetrated from the small-caliber end of joint, again the end of carbon steel pipe is increased thick, fiber is dispersed in the pouring cup of joint inside, and keeps carbon steel pipe and taper hole coaxial
Then the end of carbon steel pipe is increased and is slightly evenly distributed in pouring cup, and cast in the end of the carbon steel pipe in pouring cup, the end of carbon steel pipe and joint are cast on together, the resinae adhesive that cast material selection intensity is high;
Then casting position is carried out natural consolidation or added hot consolidation;
Finally, to Casting Joint and the pre-stretch-draw of thickened portion, make the fiber of thickened portion stressed evenly, to improve overall rupture pull force.
Engine exhaust pipeline interface arrangement of the present invention and production method thereof, compared with prior art, solved soft rigging equal strength casting problem, especially, for example, for high strength fibre pipe: aramid fiber, superhigh molecular weight polyethylene material fibre pipe, PBO material fiber pipe texts is obvious.
