Can process difform Stamping Steel Ribbon according to concrete application demand.With reference to figure 2～5, be respectively have the stiffening rib housing, the Stamping Steel Ribbon of dull and stereotyped housing, groove housing and part groove housing.Similar with Fig. 1, in Fig. 2～5 21,31,41 and 51 are foaming body, described foaming body is formed by the improvement polyurethane foam of one-component, the surface of described foaming body is coated with one deck can waterproof, polyurethane film 21a, 31a, 41a and the 51a of grease proofing one-component, housing is a working of plastics, its shape is respectively stiffening rib housing 22, dull and stereotyped housing 32, groove housing 42 and part groove housing 52 according to concrete application demand and different.
Introduce the machining process of Stamping Steel Ribbon provided by the utility model below in detail.
At first, housing is carried out pretreatment.
Housing provided by the utility model is the working of plastics housing, and certainly, described housing can also be other material, and for example which kind of material no matter rubber etc. be, all will carry out pretreatment to housing before the preparation Stamping Steel Ribbon.Pretreated purpose is that the part that makes housing be connected with foaming body can have viscosity preferably, is convenient to housing and foaming body bonds together securely.
The utility model adopts plasma high-frequency corona equipment to carrying out ion beam bombardment with the contacted part of foaming body on the housing, the high-energy particle bombardment surface of shell that sends of shockproof air ion bundle by innovation, thereby removed the organic or inorganic dirt of surface of shell, activating surface produces reliably bonding functional group simultaneously.Compare over and adopt expensive poisonous organic solvent to remove the method for the organic dirt on the housing, this method is economy, safety not only, and powerful, effectively, this method makes and has also reduced the discharging of volatile compound with the contacted part of foaming body when forming long-acting all one sides cohesion on the housing.And housing after treatment can not cause scar to treated side, can not influence the gloss of housing yet.
Secondly, debugging foaming machine parameter.
One-component polyurethane mixes by the special-purpose machinery foam device with pressurized air, regulates one-component polyurethane and compressed-air actuated mixed proportion, makes air dispersion in polyurethane, thereby reaches the requirement of corresponding expansion ratio.
The device parameter of described special-purpose machinery foam device specifically is adjusted to:
Gas injection cylinder discharge pressure table: the pressure minimum predefined value is 5MPa, and the pressure maximum predefined value is 30MPa;
Flow setting type cylinder interior pressure gauge: the preset pressure value when discharging gas is 14MPa, and the pressure maximum predefined value is 30MPa;
Degree of vacuum: the pressure minimum predefined value is 0.4MPa, and the pressure maximum predefined value is 0.6MPa;
The gas injection cylinder drives barostat: predefined value is 0.35MPa;
Steady pressure value when pneumatic motor (upper pump) is supplied with material is (8.5 ± 0.5) MPa;
Temperature is (85 ± 5) MPa in the oven.
The 3rd, access program by robot coating one-component polyurethane foam.
The utility model is finished coating one-component polyurethane and then is made it form foaming body by robot by programme controlled method, and the concrete steps of caller are:
1, cursor is moved to first point of formula, speed transfers to low speed, by [advancing] key the mechanical arm of robot is taken to first position.
2, check by [advancing] key whether each formula point is correct, whenever by the key that once [advances], mechanical arm will move a formula point.
3, when cursor is displaced downwardly to non-moving formula row, mechanical arm will can not move to down a bit, and need skip cursor this non-moving formula row this moment, the formula point below continuing to confirm.
4, robot is taken to first position.
5, pin [chain]+[test run] key, mechanical arm will intactly move all formula row of this formula one time.
The 4th, manipulator coating one-component polyurethane foam.
Concrete operating process is:
1, with manipulator one-component is improved polyurethane material and be coated in the foaming mould, the temperature of foaming mould is between 35 ℃～40 ℃.
Here, described foaming mould can be difformity, the different big or small cavity mould of making according to concrete application demand, and the material of described foaming mould is a Teflon.By program control machine hand, the improvement polyurethane material of one-component is coated in the foaming die cavity.
2, housing is bondd with the form of embedding or contact and the improvement polyurethane of one-component, and fixation.
3, whole foaming mould is sent into oven.
The 5th, material cured.
The temperature of oven is arranged between 80 ℃～90 ℃, and the time that whole foaming mould solidifies in oven is set to 5min～6min.
The 6th, lay down the foaming mould, and whether the check Stamping Steel Ribbon has damaged.
Because the foaming mould adopts the Teflon material,, separate than being easier to so the improvement polyurethane of foaming mould and one-component can not bond together.
The machining process of above-mentioned Stamping Steel Ribbon is simple, easy to operate, and low, the long service life of making of Stamping Steel Ribbon cost is used in air-strainer on the various vehicles or the air-strainer on the air-conditioning especially, can also be used in above the door and window firm and durable simultaneously.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
