Description
Technical field
The present invention relates to a kind of hand tools and manufacture method, a kind of specifically pipe wrench and manufacture method, pincers handle body is made up of glass-fiber-reinforced polyamide 66 and the inserts that embeds in it, concentrate the cross section to strengthen to pipe wrench stress, and adopt specific method of manufacturing technology, guarantee that pipe wrench has enough rigidity and intensity.The invention provides a kind of simple in structure, the intensity height, cost is low, and is in light weight, the industrial standard pipe wrench of anticracking and easy operating.
Background technology
Pipe wrench is the indispensable instrument during pipeline is installed, and also is that other industry is as instrument commonly used in the industry such as machinery, boats and ships, chemical industry.Moral formula at present commonly used and American pattern pipe pliers handle casts with metal alloy and are formed, and this pipe wrench handle intensity is higher, but production cost is higher, pipe wrench is heavier, on-insulated, be unfavorable for problem existence such as cold day operation.Form with nylon injection-molding as if the pincers handle, then can cause clamping the handle fracture owing to stress is concentrated, nut is easily pressed nylon and is collapsed during work, as if adding one inserts in pincers handle body, owing to the coupled problem between pincers handle and the nylon ftractures, causes clamping handle and loses efficacy.
Therefore, the structure of nylon pipe wrench needs to optimize, and manufacturing process needs innovation.
Summary of the invention
The purpose of this reality invention by the optimization of nylon tube wrench structure and the innovation of manufacturing process, provides a kind of intensity higher, simple in structure in order to overcome the deficiency of above-mentioned technology, and cost is low, and is in light weight, insulation, the industrial standard pipe wrench of anticracking and easy operating.
The present invention solves the scheme that its technical problem takes:
Inserts strengthens the nylon pipe wrench and is made up of moving jaw, regular jaw, adjusting nut, pincers handle body etc., pincers handle body is by glass-fiber-reinforced polyamide 66(nylon) form with the inserts that embeds in it, inserts (5) is a symmetrical structure, form by whole or two parts, be one " L " type, on be " U " type, be down " worker " type structure.Inserts (5) can adopt inserts A (51), or inserts B(52), or inserts C(53) structure, concentrate cross section (7) to strengthen to pipe wrench stress, or increase the rigidity and the intensity of nylon pincers handle.
Inserts or employing divide the inserts B(52 of body structure), it has assembly (521) and i shaped steel inserts (522) two parts to form; Inserts B(52) be a symmetrical structure, assembly (521) is one " L " type, goes up " U " type, and for falling " recessed " type structure, i shaped steel inserts (522) is the I-shaped structure down.I shaped steel inserts (522) all is embedded in the pincers handle bodies (1), is separated with the nylon layer of one deck 2 ~ 6mm between assembly (521) and i shaped steel inserts (522); Assembly (521) is after pincers handle body is finished injection mo(u)lding, by screw (15) and screw hole A (18) and screw hole B(181) be connected on the pincers handle bodies (1); Inserts or adopt integrally-built inserts C(53), be that two parts of inserts B unite two into one, or following " worker " type structure division of inserts A (51) extends.
I-shaped structure is the design of variable cross-section equal strength along pincers arbor line.The web of the I shape of inserts part can design many eyelets, and filled nylon during injection moulding can strengthen the bond strength of inserts and nylon, tears when preventing work.
Two inwalls of inserts top " U " type structure overlap with the both sides hole wall of pincers handle body installing hole respectively, and inserts end face (8) and end face (9) be 2mm ~ 5mm or concordant apart, and remainder is positioned at and clamps handle body (1), and its surperficial nylon thickness is 2 mm ~ 6mm.
The locating hole A(6 that inserts A (51) in pincers handle body injection mold is is 3mm ~ 6mm by two diameters) and with core (14) surface (12) contacted inwall (13) locate.When injection moulding, i shaped steel inserts (522) is by locating hole B(22) in mould, locate
Between assembly (521) and i shaped steel inserts (522) or do not have a nylon layer, it links to each other by screw (15) is accurate.
Main method of manufacturing technology is: surface treatments such as inserts casting or cutting of material, inserts deburring rounding, inserts shot-peening, inserts coupling processing, inserts preheating, inserts are located assembling, injection moulding, cooling, detection at mould.Inserts A (51), inserts B(52) assembly (521) partly, inserts C(53) adopt the method manufacturing of casting, and carry out heat treatment reinforcement; Inserts B(52) i shaped steel inserts (522) part adopts i shaped steel; The inserts material adopts 0.5mm～8mm thickness.
Surface treatments such as inserts (5) eliminates rust before use, shot-peening are handled the back and were used in 1 ~ 10 hour, otherwise should handle again; The inserts processing that before injection moulding, should be coupled, couplant can adopt NL-6620, NL-6610, nylon glue etc., and processing must evenly put in place, handles the back and is no more than 1 ~ 20 hour with using space before; Needed inserts is carried out suitable preheating before clamping handle body (5) injection moulding, preheat temperature is controlled at 40 ℃～200 ℃, and plastic is noted suitable insulation winter in indoor cooling naturally after the injection moulding; Pincers handle bodies (5) are when injection moulding, and cast gate should be opened near pincers handle body head, should not open at pincers handle body afterbody; Injection machine should have according to the size of pincers handle body selects big model, to guarantee enough injection pressures and pressurize.Plastic is put into water and was boiled 0.5 ~ 2.0 hour after the injection moulding.
Beneficial effect of the present invention: (1) pincers handle of the present invention body is to be made of glass-fiber-reinforced polyamide 66 and inserts, has alleviated the weight of pincers handles greatly, is convenient to operate and carry.
(2) pincers handle body of the present invention also plays a part insulation, and the winter protection in winter has increased user's the comfort and the sense of security.
(3) will clamp the handle body and be embedded in inserts, the stress that can reduce to clamp the handle body is concentrated, and increases the intensity of pipe wrench.
(4) eliminate rust before inserts uses, surface treatment such as shot-peening, processing is coupled before injection moulding, inserts is carried out suitable preheating, plastic is in technologies such as indoor slow cooling after the injection moulding, inserts adopts down increase rigidity such as " recessed " type structure, I-shaped structure, these methods have guaranteed, reduce the slippage of the two when pincers handle body is stressed, prevent to clamp handle body cracking.
(5) adopt inserts end face 8 concordant with end face 9, nut is pressed the phenomenon of collapsing to nylon when having prevented work.
(6) it is higher, simple in structure to the invention provides a kind of intensity, and cost is low, and is in light weight, insulation, the industrial standard pipe wrench of anticracking and easy operating.Adopt inserts A can reach aluminium handle standard; Adopt inserts B or inserts C-structure can reach handspike standard.
