Description
Technical field
The present invention relates to a kind of plastic tap water channel Vibration welding technique, mainly apply to shower faucet, kitchen dragon
In the production technology of the plastic tap water channel such as head, tap for washbasin.
Background technology
As living standards of the people are increasingly improved, to life environmental quality requirement also more and more higher, in family kitchen, health
Between tap used cross water water channel and use copper material mostly, the chemistry that certain proportion lead, arsenic etc. are harmful is contained in copper material
Composition, causes consumer's body hidden danger disease, at present many bathroom companies all to copper material cross tap water channel and other are matched somebody with somebody
Part carries out technological innovation, replaces copper material using the plastic material for meeting U.S.'s NSF certifications, with more plastics such as at present
The engineering plastics such as POM, PPO, PPS, PA, PPA.The plastic material that tap water channel material is changed to meet NSF by copper material is crossed,
Material cost and part processing cost are greatly lowered, and reduce copper material and cross injury of the heavy metal to human body contained by water water channel, from
And lift the competitiveness of product in market.
When routinely injection cannot produce plastic tap water channel, prior art is mainly using hot plate Welding, rotation welder
The Joining Technology methods such as skill, laser Welding, supersonic welding technique, these approach applications are primarily present following when engineering plastics
Problem：
Hot plate welding：
1. welding deformation is big, and postwelding flash is more, and easy plug-hole influences flow, and flash easily to drop into drinking water,
It is unhealthful；
2. pre- influence of thermal deformation is received, weld size and sealing cannot be ensured.
Spin welding：
1. weld strength is unstable；
2. weld length is difficult to control.
Laser Welding：
1. material needs two kinds, a kind of printing opacity, a kind of extinction；
2. weld strength is unstable.
Supersonic welding：
1. weld strength is unable to reach requirement.
For this reason, it may be necessary to design a kind of weld strength stabilization, it is easy to control, it is ensured that the plastic tap water channel of connection sealing
Welding method.
The content of the invention
The present invention is improved to above mentioned problem, i.e., the technical problem to be solved in the present invention is that a kind of guarantee connection of design is close
The welding method of the plastic tap water channel of envelope property.
To achieve the above object, the present invention provides following technical scheme：A kind of plastic tap water channel Vibration welding work
Skill, it is to weld sub-assembly to use plastic tap water channel, including epimere and hypomere, and epimere is deck portion, and hypomere is water way portion,
Two sections are welded by face wheel profile surface, and two sections use engineering plastics injection moulding, first in vibration friction welding (FW) during welding
Epimere and hypomere are fixed on fixture on picking are welded.
Preferably, described welding parameter condition is as follows：Vibration frequency is 220~260Hz, 0.4~1.8mm of amplitude, weldering
It is in the range of 20sec, 1.3~1.8mm of weld penetration to meet 200~1000Kg.f of pressure, weld interval.
Further, described vibration friction welding (FW) is purely mechanic welding, in welding process using between two workpiece through too strong
The heat that strong linear contact vibration friction is produced, is melted weld material, and postwelding is processed by the pressurize of a period of time again,
Spread by the mutual infiltration in weld seam both sides, connect together both sides workpiece, traditional fusion welding method can be prevented effectively from
Because of defects such as weld contamination, stomata, the crackles using additive appearance.Using vibration friction welding (FW), melt material connection is being realized
On the basis of, pressurize can be processed after vibrating friction welding (FW) again, by strengthening the dense structure's property of commissure, realize that weld strength is carried
Rise.
Further, when the epimere is welded with hypomere, it is respectively arranged in weld seam or so outside for welding end surface specification
One Flash traps, to control flash to move towards, weld width ratio in narrow/wide side designs 2/3 to design Flash traps, by optimization
The interrelated geometrical parameters of part weld seam, it is ensured that the Homogeneouslly-radiating at each position of weld seam in welding process, and butt welding practices midwifery raw flash
Play guide functions.
In addition, to avoid fixture and the epimere improper friction of generation occur in welding process, outside epimere deck portion
Design Orientation muscle increases the effective friction between weldment at.
Compared with prior art, the beneficial effects of the invention are as follows：Current plastic tap water channel is this method solve, especially
Easily there is weldering using methods such as hot plate Welding, rotation Welding, laser Welding, supersonic welding techniques in engineering plastics articulated
Connect intensity difference, deflection is big, and flash is more, the problems such as sealing cannot be ensured, so as to reduce production cost, improve production matter
Amount, the present invention is defined by terms of welding procedure, welding structure, welding parameter etc., is capable of achieving larger fusion penetration, lifting
Bonding strength level and its distributing homogeneity on whole weld seam, assembly precision etc., and Member Welding deformation is reduced, meet and produce
Product design, manufacture demand.
