Abstract
The utility model relates to a shaping mold for a specific end face welding screw. The mold comprises an upper mold and a lower mold, wherein an upper mold core is arranged inside the upper mold; a lower mold core is arranged inside the lower mold; both the upper mold core and the lower mold core are made of hard alloy materials; a head part shape cavity in match with the head part of the end face welding screw and an arc strike point shape cavity communicated with the head part shape cavity are arranged at the bottom of the upper mold core; an end face welding screw rod part shape cavity is arranged inside the lower mold core; the bottom of the rod part shape cavity is of an inverted cone shape; and a product ejecting pin is further arranged inside the lower mold. According to the scheme of the utility model, by analyzing the structure of a non-standard screw, a specific shaping mold is designed, thus with the adoption of the specific mold, qualified non-standard specific end face welding screws are produced after raw materials are pre-machined; the production is simple and convenient, and continuous production can be carried out without machine work procedures; the production efficiency is improved greatly; and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of special-purpose end face welding screw mould.
Background technology
The welding of end face screw is meant between the end face of metal or metalloid spare and another metal works surface and produces electric arc, exerts pressure rapidly during to be joined fusing, accomplishes a kind of method of welding.This new welding technology is quick, reliable, simple, cost is low; Industries such as bridge, highway, building construction, shipbuilding, automobile, power station, electrical control cubicles have been widely applied at present; But welding low-carbon steel, stainless steel, low-alloy steel, the double-screw bolt of copper, aluminium and alloy material thereof, weldering nail, pin, peg etc.Along with China's car industry development in recent years is rapid, increasingly high to the production technology and the kind requirement of all kinds of securing members, except standard fasteners; Also need the preparing various kinds nonstandard product, to adapt to the needs of industry development: such as special-purpose end face welding screw on the automobile, its head is bigger; Bar portion is more elongated; Regulation steady-state deformation cold forging ratio must be less than 3 times in cold heading technique scientific principle opinion, otherwise leading edge deformation is difficult, is difficult to continuous production; So the end face of this structure welding screw deformation, and the striking dot structure on the end face is difficult to realize on common die, causes this kind production difficulty.
The utility model content
The utility model purpose is that a kind of special-purpose end face welding screw mould of producing nonstandard end face welding screw is provided for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of special-purpose end face welding screw mould, comprise upper die and lower die, and be provided with upper cores in the said patrix; Be provided with down die in the said counterdie; Said upper cores, following die all adopt Hardmetal materials to process; Said upper cores bottom is provided with the head shape chamber that is complementary with end face welding screw head, the striking point shape chamber that communicates with head shape chamber; Be provided with end face welding shank of screw portion shape chamber in the said die down; Bottom, said bar portion shape chamber is back taper.
Preferably, also be provided with the product knock pin in the said counterdie.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The special-purpose end face welding screw mould of the utility model scheme through analyzing the structure of nonstandard screw, is designed a moulding mould special; Make raw material after preprocessing, produce qualified nonstandard special-purpose end face welding screw, produce simple and convenient through this particular manufacturing craft; And can carry out continuity production; Need not to carry out machining processes, improved production efficiency greatly, reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the special-purpose end face welding screw mould of the utility model;
Wherein: 1, patrix; 2, counterdie; 3, upper cores; 4, following die; 5, head shape chamber; 6, striking point shape chamber; 7, bar portion shape chamber; 8, product knock pin.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1 is the described a kind of special-purpose end face welding screw mould of the utility model, comprises patrix 1, counterdie 2, is provided with upper cores 3 in the said patrix 1; Be provided with down die 4 in the said counterdie 2; Said upper cores 3, die 4 all adopts Hardmetal materials to process down; Said upper cores 3 bottoms are provided with the head shape chamber 5 that is complementary with end face welding screw head, the striking point shape chamber 6 that communicates with head shape chamber 5; Be provided with end face welding shank of screw portion shape chamber 7 in the said die 4 down; 7 bottoms, said bar portion shape chamber are back taper; Also be provided with product knock pin 8 in the said counterdie 2, after formed product finishes, product deviate from from following die 4.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
Claims (2)
1. a special-purpose end face welding screw mould comprises upper die and lower die, it is characterized in that: be provided with upper cores in the said patrix; Be provided with down die in the said counterdie; Said upper cores, following die all adopt Hardmetal materials to process; Said upper cores bottom is provided with the head shape chamber that is complementary with end face welding screw head, the striking point shape chamber that communicates with head shape chamber; Be provided with end face welding shank of screw portion shape chamber in the said die down; Bottom, said bar portion shape chamber is back taper.
2. special-purpose end face welding screw mould according to claim 1 is characterized in that: also be provided with the product knock pin in the said counterdie.
