Abstract
The invention discloses a dedicated end-face welding screw molding die, comprising an upper die and a lower die, wherein the upper die is provided with an upper mold; the lower die is equipped with a lower mold; both the upper mold and the lower mold are made of sintered carbide materials; a head-shaped cavity and a pilot arc point shaped cavity are arranged at the bottom of the upper mold, wherein the head-shaped cavity matches with the head of the end-face welding screw, and the pilot arc point shaped cavity communicates with the head-shaped cavity; a rod shaped cavity of the end-face welding screw is arranged in the lower mold and provided with an inverted-cone bottom; and a product ejector pin is also positioned in the lower mold. The scheme in the invention analyses structures of non-standard screws and designs a special mold so that the raw material is pre-processed to produce qualified non-standard end-face welding screws through the special mold; and the invention is characterized by simple and convenient production, capability of continuous production and no need for machining processes, thus greatly improving the production efficiency and reducing the production cost.
Description
Technical field
The present invention relates to a kind of mould, relate 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.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of special-purpose end face welding screw mould of producing nonstandard end face welding screw.
Technical solution of the present invention is achieved in that a kind of special-purpose end face welding screw mould, comprises upper die and lower die, is 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 present invention compared with prior art has advantage:
The special-purpose end face welding of the present invention screw mould 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 technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of special-purpose end face welding screw mould of the present invention;
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 the present invention is described.
Accompanying drawing 1 is a kind of special-purpose end face welding screw mould of the present invention, 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.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
