Abstract
The invention relates to a molding process for a nonwovens-wound type automobile intake tube, comprising the following steps of: (1) cutting a nonwovens raw material into strips with the width of 10-50mm; (2) uniformly and obliquely winding the nonwovens strips on a core rod in a running direction towards one side of the core rod, simultaneously and synchronously winding hard nylon yarns with the diameter of 1-5mm on the nonwovens strips, and uniformly brushing gluewater on the nonwovens strips on the side of the hard nylon yarns in the running direction of the nonwovens strips along the core rod; and (3) after winding is completed, baking or naturally airing for molding, and taking down a finished product from the core rod. By the steps of uniformly winding the nonwovens strips and the hard nylon yarns on the core rod at intervals in a small angle as well as bonding and molding, the advantages of simple manufacturing process and short molding period are achieved, and the obtained nonwovens-wound type automatic intake tube has the assembly properties of strength, flexibility, noise reduction, distortion resistance, ageing resistance and the like, can meet rigid requirements on any certain bending for the butt joint of an automobile engine and an air filter under different assembly working conditions, and has the advantages of long service life, recyclability and no waste pollution.
Description
Technical field
The present invention relates to a kind of forming method of automotive air intake pipe, a kind of specifically forming method that utilizes nonwovens to be wound in the automotive air intake pipe.
Background technique
The orthodox car air feeder structure adopts the polypropylene injection molding part to be connected on the motor car engine by Stamping Steel Ribbon, and the polypropylene injection molding part needs to customize according to installing space in the car, and component are many, and the cost of production height is assembled loaded down with trivial details, poor for applicability.Existing automotive air intake pipe adopts rubber corrugated pipe, rubber corrugated pipe power consumption of polymer processing height, cost height, intensity is low after bending is installed, and aging quality resistance is poor, in case aging breakage can greatly influence the working life of motor, can not reduce noise effectively, reclaim the not easy secondary pollution that causes.
Summary of the invention
The automotive air intake pipe adopts the polypropylene molding and forming in the prior art in order to solve, its complex structure, component are many, assemble loaded down with trivial details, poor for applicability, and employing rubber corrugated pipe, its fabricating cost height, the flexural strength poor performance, aging quality resistance is poor, noise reduction is poor, working life is short, easily cause deficiencies such as secondary pollution, the invention provides a kind of nonwovens winding type motor suction tude moulding process, this forming method technology is simple, shaping speed is fast, combine the soft or hard characteristic of nonwovens and hard nylon wire after the moulding, overall flexibility is good, the intensity height, the bending hardness height, high temperature resistant, low temperature, anti-aging, long service life is convenient to reclaim.
The technical solution used in the present invention is: a kind of nonwovens winding type motor suction tude moulding process is characterized in that may further comprise the steps:
(1) the nonwovens raw material is cut into wide rectangular of 10-50mm;
(2) the rectangular inclination uniform winding of above-mentioned nonwovens is walked on one side to plug on plug, simultaneously the hard nylon wire of diameter 1-5mm is wound in synchronously nonwovens rectangular on, and on the rectangular nonwovens along hard nylon wire one side on the plug direction of travel of nonwovens is rectangular even brushing glue, any circle nonwovens rectangular with hard nylon wire parcel compress through glue be bonded in the rectangular last circle nonwovens of an above-mentioned circle nonwovens rectangular on;
(3) twine finish after, through baking moulding in 1-2 hour, or natural airing 20-25 hour moulding, take off by plug after the moulding and get final product.
Described hard nylon wire is baking when twining and partly melts state.
Described nonwovens rectangular with the plug angle be 80-87 °.
Described hard nylon wire along the rectangular width direction center line of nonwovens be wound in nonwovens rectangular on.
After adopting above technological scheme, the beneficial effect that the present invention reaches is: the rectangular small angle that is of nonwovens twines on plug, be pressed on the rectangular width direction center line of nonwovens by partly melting state, the two circle nonwovens that twine mutually are rectangular adhesion-molded through glue, nonwovens is small angle and twines, the whole tensile strength height in Wrapping formed back; The hard nylon wire is partly melting the plug winding of state lower edge, and it is convenient to twine, effective at the aftershaping that cools down, and plays skeleton and supports the nonwovens effect; Nonwovens is rectangular through glue the hard nylon wire is bonded in wherein for two circles that mutually twine, combine the soft or hard characteristic of nonwovens and hard nylon wire, good, the anti-twist intensity height of pliability after the moulding, can satisfy motor car engine and any crooked certain rigid requirement of empty filter butt joint needs under the different assembling operating modes, overall structure is with short production cycle, technology is simple, and processing cost is low; Nonwovens plays sound-absorbing and reduces the effect of making an uproar, hard nylon wire high-and low-temperature resistance, anti-aging, and long service life is convenient to recycling, no secondary pollution.
Automotive air intake pipe of the present invention adopt nonwovens rectangular with the hard nylon wire evenly be at interval small angle on plug, twine, adhesion-molded, preparation process is simple, molding cycle is short, reach intensity, pliability, noise reduction, assembly performance characteristic such as anti-twist, anti-aging, can satisfy motor car engine and any crooked certain rigid requirement of empty filter butt joint needs under the different assembling operating modes, long service life, recyclable utilization again, no waste is polluted.
