Description
Technical field: the present invention relates to a kind of manufacture method of the lamp stand that throws light on, relate in particular to a kind of method of utilizing reinforced composite to make hollow illumination lamp stand.
Background technology: at present, widely used traditional lamp stand is hollow metallic rod or Hollow cement pile mostly; Defectives such as these two kinds illumination lamp stands exist all that insulating properties are poor, Heavy Weight, perishable, surface maintenance cost of upkeep height, color are single.For this reason, a kind of hollow illumination lamp stand of being made by reinforced composite such as glass fiber resin arises at the historic moment, this lamp stand have good insulation preformance, in light weight, intensity is high, corrosion-resistant, plurality of advantages such as appearance luster is bright-coloured, cost is low.
Publication number is that the patent of invention that " CN1117552A ", name are called " hollow glass lamp, flag round bar and production method and equipment " discloses a kind of method of making the fiberglass lamp stand, it is glass fabric to be wrapped on the plug and with it send in the conical mould, the start rotary die, treat that glass fabric unclamps and is close to mould inner wall from plug under action of centrifugal force after, take out plug; In mould, spray quantitative resin then and continue rotary die, treat that resin soaks into the back to mold heated with glass fabric, shuts down the demoulding behind the resin solidification.Though this method is fairly simple, there are many shortcomings:
1. only depend on action of centrifugal force the air that accumulates between the glass fabric can not be discharged fully, therefore form a large amount of bubble or cavity easily, reduced the intensity of lamp stand, rupture at fault locations such as bubble, cavities easily;
2. because glass fabric is close to mould inner wall, resin is difficult to that outer surface with lamp stand coats fully or clad is thinner, therefore causes the segment glass fabric exposed easily, has influenced the intensity and the presentation quality of lamp stand;
3. owing to there is not rolling step, thus the lamp stand density of material less, organize more loosely, lamp stand hardness and intensity are lower;
4. because reinforcing bar can't be set in lamp stand, so the rigidity of lamp stand is little, wind loading rating weak, flexural deformation easily, so length is unsuitable long;
5. need after the demoulding to the outer surface of lamp stand polish, surface treatments such as repairing, japanning, operation is various.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of production method of reinforced composite illumination lamp stand, not only hardness is big, rigidity is strong, bending strength is high, presentation quality is good to utilize the lamp stand that this method makes, and lamp stand length can prolong significantly.
To achieve these goals, the present invention is by the following technical solutions:
1) some spirals evenly is fixed in the steel reinforcement cage network framework that forms the circular cone column on the anchor clamps;
2) solidifying the thickness that one deck has color in the mode of centrifugal forming in scribbling the tapered tube shape mould of releasing agent is the gel coating resin of 0.5～1.5mm;
3) glass fabric is wrapped in the surface of described steel reinforcement cage network framework, by described anchor clamps the steel reinforcement cage network framework is inserted in the above-mentioned mould then;
4) utilize the positioning and locking element of anchor clamps that the steel reinforcement cage network framework is fixed in the described mould, guarantee the described gel coating resin 3mm of each reinforcing bar distance, take out the support component of anchor clamps then;
5) pass through the hydraulic haulage machine with steel bar stretching;
6) inject quantitative resin mixture from the small end of mould, treat that opening motor when this resin mixture flow to the big end of mould makes the mould rotation, rotating speed is controlled at 800～1200 rev/mins;
7) treat after described resin mixture is evenly distributed rotating speed to be kept to 250 rev/mins in mould, insert jet pipe, evenly spray haydite or quartz sand that granularity is 1～2mm to big end from mould; Meanwhile, in mould, put into the plug roll extrusion, until resin solidification;
8) shutdown, the demoulding, cut off reinforcing bar, the positioning and locking element is separated with lamp stand.
Described resin mixture is that 20～30% thermosetting resin and 70～80% inserts mix by percentage by weight, described inserts or be 1～2mm haydite or be 1～2mm quartz sand or be the glass fibre of 8～15mm for length for granularity for granularity.
Compared with the prior art, the present invention is owing to adopted technique scheme, and therefore the lamp stand of making has plurality of advantages such as hardness height, rigidity is strong, bending strength good, smooth in appearance is attractive in appearance, makes a concrete analysis of as follows:
1. owing to substituted the plug in the conventional method with anchor clamps, therefore can will make steel reinforcement cage network framework be arranged in the mould by these anchor clamps and finally form the lamp stand skeleton, thereby improved the rigidity and the bending strength of lamp stand, not only can prolong significantly lamp stand length, but also strengthened the wind loading rating of lamp stand;
2. owing to need not to unclamp with being wrapped in the outer glass fabric of steel reinforcement cage network framework, the inwall of glass fabric and mould is the interval certain clearance also, therefore resin mixture can be filled in this gap and with glass fabric and coat fully, retrains, thereby overcome the exposed easily defective of conventional method glass fabric, both improved product presentation quality, improved yield rate, further strengthened the intensity of lamp stand again;
3. owing to having adopted rolling step, the air extrusion that therefore not only can accumulate in glass fabric is discharged, and resin mixture is fully flowed and sized glass fibres cloth, is easy to generate bubble or empty defective thereby eliminated conventional method; In addition, adopt the plug roll extrusion, it is tightr that resin mixture is combined with glass fabric, improved the density of material, and it is more loose to have overcome the conventional lights bar material, the defective that hardness and intensity are lower;
4. sandblast operation both can further improve the intensity of lamp stand, can reduce again resin consumption, reduce cost;
5. owing to set in advance gel coating resin, thus need not after the demoulding to lamp stand polish, polish, surface treatments such as repairing, japanning.
