Description

A kind of cold upsetting die of car manufacturing flat side's stud
Technical field
The utility model relates to five metals parts and makes field, refers in particular to a kind of cold upsetting die of car manufacturing flat side's stud.
Background technology
Traditional flat side's stud structure is simple, and cost is low, but in use insecure, uses also dumb, and concentricity, Product Precision are also arrived requirement.Flat side's stud structure is special, structural requirement is higher, the manufacturing process of existing flat side's stud is machining work center and produces, its existing technological process is: will cut material deliver to machining center carry out turning, milling, thread rolling 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 purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of disposable cold-heading molding, does not need lathe instrument to process, more saves material, the cold upsetting die of car of low cost of manufacture.
For achieving the above object, technical scheme provided by the utility model is: a kind of cold upsetting die of car manufacturing flat side's stud, it includes the upper die and lower die cooperatively interacted, described counterdie includes lower die model core, counterdie fixed cover, lower model fixing seat, counterdie overcoat, wherein, lower die model core main body is 25mm by diameter, height is that the cylinder of 85mm is formed, main center top is provided with the lower nut die cavity that diameter is 13.7mm, and lower nut die cavity is communicated with the stepped counterdie nibs running through lower die model core main body; Counterdie nibs is up big and down small syllogic mechanism, its stepped cavity diameter be communicated with lower nut die cavity is 9.1mm, and be highly 45.6mm, middle part stepped cavity diameter is 7.4mm, lower step chamber diameter is 5.4mm, connects between adjacent steps chamber by being tilted over filter chamber; Lower die model core main body is sleeved in counterdie fixed cover, and counterdie fixed cover periphery top contraction forms stepped retainer ring, and is contained in counterdie overcoat top by this Fixing shrink ring; Flush bottom lower die model core, counterdie fixed cover and be assemblied on lower model fixing seat, lower model fixing seat main body is sleeved on counterdie overcoat bottom; Lower model fixing seat center is provided with and the counterdie push rod chamber be connected bottom counterdie nibs.
Described patrix includes lower die model core, patrix overcoat, wherein, lower die model core is sleeved in patrix overcoat lower central groove, lower die model core main body is 20mm by diameter, it is highly the cylinder formation of 25mm, place of lower die model core main center is provided with the patrix nibs matched with counterdie nibs, and patrix overcoat top is provided with the patrix push rod chamber be communicated with patrix nibs.
The utility model is by the improvement to mould, make flat side's stud adopt cold-heading one-shot forming, thus decrease the program of instrument processing, ensure that concentricity and improve the precision of flat side's stud, 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 utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, the cold upsetting die of car of the flat side's stud of the manufacture described in the present embodiment includes the upper die and lower die cooperatively interacted, described counterdie includes lower die model core 1, counterdie fixed cover 2, lower model fixing seat 3, counterdie overcoat 4, wherein, lower die model core 1 main body is 25mm by diameter, height is that the cylinder of 85mm is formed, main center top is provided with the lower nut die cavity 6 that diameter is 13.7mm, lower nut die cavity 6 is communicated with the stepped counterdie nibs 5 running through lower die model core 1 main body, counterdie nibs 5 is up big and down small syllogic mechanism, its stepped cavity diameter be communicated with lower nut die cavity 6 is 9.1mm, and be highly 45.6mm, middle part stepped cavity diameter is 7.4mm, lower step chamber diameter is 5.4mm, connects between adjacent steps chamber by being tilted over filter chamber, lower die model core 1 main body is sleeved in counterdie fixed cover 2, and counterdie fixed cover 2 periphery top contraction forms stepped retainer ring, and is contained in counterdie overcoat 4 top by this Fixing shrink ring, flush bottom lower die model core 1, counterdie fixed cover 2 and be assemblied on lower model fixing seat 3, lower model fixing seat 3 main body is sleeved on counterdie overcoat 4 bottom, lower model fixing seat 3 center is provided with and the counterdie push rod chamber 7 be connected bottom counterdie nibs 5.Patrix includes lower die model core 8, patrix overcoat 9, wherein, lower die model core 8 is sleeved in patrix overcoat 9 lower central groove, lower die model core 8 main body is 20mm by diameter, it is highly the cylinder formation of 25mm, place of lower die model core 8 main center is provided with the patrix nibs 10 matched with counterdie nibs 5, and patrix overcoat 9 top is provided with the patrix push rod chamber 11 be communicated with patrix nibs 10.Raw material are cut into predetermined length workpiece by shearing by this programme; Forward extrusion becomes the cylindrical workpiece of predetermined length, to form bar portion and head; Backward extrusion head, to form predetermined bulb, 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 then carry out thread rolling to the bar portion of flat side's stud, thread-rolling screw is shaping, obtains described flat side's stud.Whereby, this programme working (machining) efficiency is high, more saves material, and cost of goods manufactured is low.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
