The processing and production method of the protecting cover of the mower has the following production steps: A, nylon and glass fiber are used as materials, dried and then placed into an injection molding machine; and B, the thread bush is arranged on a mold before injection and finally the injection processing and the molding are carried out.
Description
Technical field
The present invention relates to a kind of small mechanical parts and method for producing thereof, especially relate to the method for producing of a kind of grass cutter protection cap and these parts.
Background technology
At present, the hand-held mower on the market, because of do not have closed protective cover above the rope of beating the grass, so the normal out-of-flatness that pruning occurs when cutting the grass on a lawn, the lawn of repairing is uneven; And the weeds of being cut when cutting the grass on a lawn disorderly fly, and have brought the inconvenience in the work to the operator.Therefore, the technical staff thirsts for prior art is improved, and increases a protective cover on the basis of existing technology, and the weeds of being cut when avoiding cutting the grass on a lawn disorderly fly.And in order better to save cost, the technical staff also develops the processing method of protective cover, achieves large-scale production.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of grass cutter protection cap and method for producing thereof, so that this protective cover can well be used on the existing mower.
For achieving the above object, the present invention is realized by following technical solution:
A kind of grass cutter protection cap, comprise cover body 1, rotating shaft bar 2,3, described cover body 1 is a circular flat, there is the moving head hole 8 of a circle centre, rotating shaft bar 2,3 be located at cover body 1 bottom and with cover body 1 single injection-molded, inner round side also is provided with a tool rest 14 outside cover body 1 bottom, and a tool rest hole 15 is arranged on the tool rest 14; The two ends of rotating shaft bar 2,3 respectively are provided with a shaft hole 4,5,6,7, are provided with screwed hole 9 and square groove 11 on thread bush fixed body 10, also are provided with two reinforcements 12,13 in rotating shaft bar 2,3 outsides.
For making this protective cover can better industrial applications, the present invention also provides a kind of method for producing of grass cutter protection cap,
The production stage of this method for producing is:
A, with raw material oven dry, drop into then in the injection machine,
On mould, install swivel nut before B, the injection moulding, last injection moulding machine-shaping.
Raw material in the described steps A are nylon and glass fibre.
Beneficial effect of the present invention is: more simple and convenient aspect the mould depanning, depanning is time saving and energy saving soon; Owing to adopt circular protective cover, the running track when beating the grass the rope cutting during with mowing is consistent; And good looking appearance is convenient to cleaning, and main is circle economical with materials to greatest extent, reduces production costs.
Description of drawings
For ease of understanding the present invention, the spy is illustrated the present invention in conjunction with the accompanying drawings.
Fig. 1 is a protective cover master TV structure schematic diagram of the present invention;
Fig. 2 is a protective cover side portion structure schematic diagram of the present invention;
Fig. 3 is a protective cover backsight structural representation of the present invention.
Embodiment
For ease of better understanding protective cover of the present invention and its method for producing, the spy is illustrated in conjunction with specific embodiments, but these embodiment should not regard any limitation of the invention as.
In conjunction with Fig. 1, grass cutter protection cap of the present invention, comprise cover body 1, rotating shaft bar 2,3, described cover body 1 is a circular flat, there is the moving head hole 8 of a circle centre, rotating shaft bar 2,3 be located at cover body 1 bottom and with cover body 1 single injection-molded, inner round side also is provided with a tool rest 14 outside cover body 1 bottom, and a tool rest hole 15 is arranged on the tool rest 14; The two ends of rotating shaft bar 2,3 respectively are provided with a shaft hole 4,5,6,7, are provided with screwed hole 9 and square groove 11 on thread bush fixed body 10, also are provided with two reinforcements 12,13 in rotating shaft bar 2,3 outsides; Hand-held operate after holding up bar to pass from moving head hole 8.
The method for producing of protective cover of the present invention is:
A, with raw material oven dry, drop into then in the injection machine,
On mould, install swivel nut before B, the injection moulding, last injection moulding machine-shaping.
Raw material in the described steps A are nylon and glass fibre.
