Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In order to illustrate technical scheme, illustrated below by specific embodiment.
An embodiment of the present invention provides a kind of production technology of hand-held head curved boom, as shown in figure 1, production technology includes
Following steps:
S1. die cast:Zinc alloy material is cast into curved boom skeleton.
In this step, specifically, as shown in Fig. 2 being the curved boom skeleton obtained after just zinc alloy material die casting.
S2. injection moulding:Crook of the arm skeleton is put into plastic mould and is molded, formed outside plastics with the side of curved boom skeleton
Shell.
In this step, specifically, being specially the step of the side of curved boom skeleton forms plastic casing in step S2:
Plastic casing is moulded on the edge of curved boom skeleton and is linked to be a circle, so that plastic casing is formed with curved boom skeleton
One dented space, as shown in figure 3, finally giving hand-held head curved boom.
Further, also include after step S2:
S3. it is surface-treated:Curved boom skeleton is surface-treated.
Wherein, step S3 is specially:
S31. sanding and polishing:Curved boom skeleton is polished.
S32. wash:Curved boom skeleton shell after polishing is cleaned.
The plastic casing is composed of the following components by weight:48.5 parts of polyphenylene sulfide, 10 parts of carbon fiber, glass
40 parts of glass fiber, processes 0.5 part of heat stabilizer, 1 part of lubricant;
Further, the processing heat stabilizer is antioxidant -1010 or antioxidant -168;
Further, the lubricant is lignite wax, OPE, wax ester or polyalcohol wax.
Another kind embodiment of the invention provides a kind of hand-held head curved boom, and hand-held head curved boom includes curved boom skeleton 10 and modeling
Material shell 20, plastic casing 20 is arranged on the side of curved boom skeleton 10.
Specifically, as shown in figure 3, plastic casing 20 is formed in the side of curved boom skeleton 10 by injection.
Specifically, as shown in Fig. 2 curved boom skeleton 10 include connecting portion 102, first end 101 and the second end 103,
First end 101 is connected with the second end 103 by connecting portion 102, and connecting portion 102 is arc, first end 101 and second
End 103 is circle.
Further, plastic casing 20 is arranged on the edge of curved boom skeleton 10 and is linked to be a circle, with the shape of curved boom skeleton 10
Into a dented space.
The plastic casing is composed of the following components by weight:48.5 parts of polyphenylene sulfide, 10 parts of carbon fiber, glass
40 parts of glass fiber, processes 0.5 part of heat stabilizer, 1 part of lubricant;
Further, the processing heat stabilizer is antioxidant -1010 or antioxidant -168;
Further, the lubricant is lignite wax, OPE, wax ester or polyalcohol wax.
Polyphenylene sulfide have high temperature resistant, corrosion-resistant, radiation hardness, non-ignitable, nontoxic, mechanical performance and excellent electrical property,
Product size good stability, the advantages of secondary operation can be carried out to product, it is combined according to a certain ratio with carbon fiber and glass fibre
Use, the not enough shortcoming of its tensile strength, bending strength can be improved, and its fire-retardant, antistatic property is reached underground coal mine
It is required that.
Another kind embodiment of the invention provides a kind of hand-held head, including above-mentioned hand-held head curved boom, support arm, rotation
Part and mounting seat;
Support arm and mounting seat are arranged on the first end of hand-held head curved boom or the second end by tumbler.
A kind of hand-held head curved boom, production technology and hand-held head that the present invention is provided, and are added using machine in the prior art
Work produces some simple profiles differences, and curved boom skeleton is obtained by die casting, obtains being arranged on curved boom skeleton by injection
Plastic casing, ultimately form hand-held head curved boom, compared with prior art, greatly reduce cost, saved many processing
Time, production efficiency is improved, and due to using mold, baroque moulding can be made, increased U.S. of product
Sense.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention,
Some equivalent substitutes or obvious modification are made on the premise of not departing from present inventive concept, and performance or purposes are identical, all should
