Abstract
The invention provides a cold-heading die for manufacturing an external-hexangular ball-head pin of an automobile. The cold-heading die comprises an upper die and a lower die which are matched with each other, wherein the lower die comprises a lower forming die main body, a fixing sleeve and a cold-heading die sleeve, the lower forming die main body is cylindrical, the cold-heading die sleeve sleeves the outer peripheral surface of the lower forming die main body, the fixing sleeve sleeves the outer side of the cold-heading die sleeve, and a plurality of inwardly-concave lower inclined grooves are formed in the outer peripheral surface of the fixing sleeve; a forming cavity which penetrates through the upper and lower ends is formed in the center of the lower forming die main body and is of a multistage-ladder shape with a big upper part and a small lower part, and the top of the forming cavity expands outwards to form a lower ball head groove; an upper ball head groove matched with the lower ball head groove is formed in the bottom of an upper forming die main body. According to the cold-heading die, through improving a process design method of the die, the concentricity and accuracy are guaranteed, the generation of relatively more wastes is avoided, and human, physical and financial resources and the like are saved.
Description
Technical field
The present invention relates to auto parts and components manufacture, refer in particular to a kind of cold upsetting die of car manufacturing automobile outer-hexagonal ball stud.
Background technology
Traditional 22-10264 ball stud structure is simple, and cost is low, but in use insecure, uses also dumb, and concentricity, Product Precision are also arrived requirement.22-10264 ball stud structure is special, structural requirement is higher, the manufacturing process of existing 22-10264 ball stud is machining work center and produces, its existing technological process is: will cut material deliver to machining center carry out turning, milling instrument processing, finally carry out the packing of product.But machining equipment is expensive, and working (machining) efficiency is low, and concentricity does not ensure, and Product Precision is also arrived requirement, and simultaneously because adopting instrument to process, can produce more waste material, therefore its metal streamline is also destroyed, and product strength is low.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of cold upsetting die of car that structure is simple, low cost of manufacture, working (machining) efficiency are high manufacturing automobile outer-hexagonal ball stud is provided.
For achieving the above object, technical scheme provided by the present invention is: a kind of cold upsetting die of car manufacturing automobile outer-hexagonal ball stud, it includes the upper die and lower die cooperatively interacted, wherein, counterdie includes anvil swage main body, fixed cover, cold-heading die sleeve, wherein, anvil swage main body is cylindrical, cold-heading die sleeve is sleeved on anvil swage main body outer peripheral face, is set with fixed cover outside cold-heading die sleeve, fixed cover outer peripheral face has the lower skewed slot of several indents; Place of anvil swage main center is provided with the die cavity running through upper and lower two ends, big up and small down multistage stepped of die cavity, and die cavity top forms lower bulb groove to external expansion; Top swage bottom part body is provided with the upper bulb groove matched with lower bulb groove, the downward convex shaped forming cone of upper bulb groove inner chamber sphere centre; Top swage main body is nested in patrix fixed cover, and patrix fixed cover outer peripheral face is up-small and down-big stepped; Its less stepped periphery is provided with skewed slot, and patrix fixed cover center is provided with the ladder die cavity be connected with upper bulb groove.
Described patrix fixed cover height is 232mm, and the cascaded surface diameter of the larger end in its underpart is 89mm, is 75mm compared with the cascaded surface of small end; Ladder die cavity upper diameter is 50mm, and become diameter 8mm hole to be connected with upper bulb groove to downward-extension 115mm after-contraction, upper bulb well width is 26.5mm, is highly 11mm.
The maximum order ladder type chamber diameter that described die cavity top is communicated with lower bulb groove is 15.2mm, and middle part ladder die cavity diameter is 13mm, and lower step die cavity diameter is 11mm, between adjacent steps die cavity by for 3mm be tilted over filter chamber.
This programme is by improving the process design method of mould, particularly the cold-heading one-shot forming that six sides make 22-10264 ball stud is increased to the improvement of mold cavity, thus decrease the program of lathe, instrument processing, ensure that concentricity and precision, avoid and produce more waste material, save manpower, physics, financial resources etc.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the invention will be further described, preferred embodiment of the present invention is: see accompanying drawing 1, the cold upsetting die of car manufacturing automobile outer-hexagonal ball stud described in the present embodiment includes the upper die and lower die cooperatively interacted, wherein, counterdie includes anvil swage main body 1, fixed cover 3, cold-heading die sleeve 7, wherein, anvil swage main body 1 is cylindrical, cold-heading die sleeve 7 is sleeved on anvil swage main body 1 outer peripheral face, be set with fixed cover 3 outside cold-heading die sleeve 7, fixed cover 3 outer peripheral face have the lower skewed slot 4 of several indents; Anvil swage main body 1 center is provided with the die cavity 2 running through upper and lower two ends, big up and small down multistage stepped of die cavity 2, and die cavity 2 top forms lower bulb groove 6 to external expansion; The maximum order ladder type chamber diameter that die cavity 2 top is communicated with lower bulb groove 6 is 15.2mm, and middle part ladder die cavity diameter is 13mm, and lower step die cavity diameter is 11mm, between adjacent steps die cavity by for 3mm be tilted over filter chamber.The upper bulb groove 8 matched with lower bulb groove 6 is provided with, the downward convex shaped forming cone 12 of upper bulb groove 8 inner chamber sphere centre bottom top swage main body 5; Top swage main body 5 is nested in patrix fixed cover 9, and patrix fixed cover 9 outer peripheral face is up-small and down-big stepped; Its less stepped periphery is provided with skewed slot 10, and patrix fixed cover 9 center is provided with the ladder die cavity 11 be connected with upper bulb groove 8.Patrix fixed cover 9 is highly 232mm, and the cascaded surface diameter of the larger end in its underpart is 89mm, is 75mm compared with the cascaded surface of small end; Ladder die cavity 11 upper diameter is 50mm, becomes diameter 8mm hole to be connected with upper bulb groove 8 to downward-extension 115mm after-contraction, and upper bulb groove 8 width is 26.5mm, is highly 11mm.During making, by shearing, raw material are cut into predetermined length workpiece; Forward extrusion becomes the cylindrical workpiece of predetermined length, to form bar portion and head; Backward extrusion head, to form predetermined bulb and circular hole, forms pre-fixed pole portion in bulb lower end; Figure begins to take shape shaping guiding, and be finally formed in same die cavity, the forward extrusion of bar portion forms six sides, and bar portion and six side one step shapings put in place.It is high that this programme has working (machining) efficiency, and cost of goods manufactured is low; Produce without cutting, material is lossless; Not easy to wear, product size precision is easy to ensure; Especially pipelining in enormous quantities is applicable to.
