Description
Technical field
This utility model relates to a kind of cold-heading device, is specifically related to a kind of for the novel cold-heading device of six sides in workpiece cold-heading.
Background technology
In metal works is carried out cold-heading during six sides.Owing to the dimensional requirement of internal six sides of different workpieces is different, therefore it is generally required to use the clamping and positioning device of different size and the cold upsetting die of car of different model just can complete the manufacture requirements of workpiece.A kind of cold upsetting die of car can only corresponding a kind of model workpiece, it is processed if the workpiece of newly-increased a kind of model needs again to manufacture or buy corresponding cold upsetting die of car, if workpiece is processed in belonging to of this kind of model workpiece on a small quantity, corresponding cold upsetting die of car will leave unused, and the most not only bothers but also wastes resource and production cost is increased.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide one and can not only complete workpiece manufacture requirements and save manufacturing cost, but also can guarantee that a secondary mould can complete six sides in common several specifications are carried out the novel cold-heading device of cold-heading.
A kind of novel cold-heading device, including upper die and lower die.Upper mold includes fixing bar, regulation cushion block, drift, swivel nut, fixed block；Threadeding with swivel nut in the lower end of fixing bar, is provided with spliced eye in fixing bar lower end；Described swivel nut upper end open, lower end is provided with annular plug；Fixed block is the cylinder of an inverted cone and is connected in the annular plug bottom swivel nut；The afterbody of drift is plugged in spliced eye, and the head of drift stretches out outside swivel nut through fixed block；The regulation cushion block for regulating drift inserting depth it is additionally provided with in spliced eye.Lower mold includes stripper, base, regulating block, block rubber.Base is provided with forming cavity, and stripper is fixed on base, and stripper is provided with guide hole corresponding to the position of forming cavity；Regulating block and block rubber are arranged on chassis interior and are positioned at immediately below forming cavity, and regulating block is above block rubber.
Further, stripper one end is provided with installing hole, and the other end is provided with V-type groove, and described slot opening direction is parallel with stripper upper surface；Stripper two ends penetrate being bolted on base of groove by a bolt penetrating installing hole and one.
Further, drift and spliced eye interference fits, drift and fixed block interference fit.
The utility model has the advantage of: reduce processing cost.Comparing with original cold-heading device, this device can be recycled and the workpiece of plurality of specifications can carry out six side's processing in cold-heading.Easy to operate, effectively improve working (machining) efficiency, reduce labor intensity.Location is reliable, and requirement on machining accuracy can be effectively ensured.Flexibly device can be adjusted according to the processing request of manufactured parts, improve its utilization rate.

Detailed description of the invention
The novel cold-heading device of one as shown in Figure 1 and Figure 2, including upper mold 1 and lower mold 7.Described upper mold 1 includes fixing bar 2, regulation cushion block 3, drift 4, swivel nut 5, fixed block 6.Threadeding with swivel nut 5 in the lower end of fixing bar 2, is provided with spliced eye 15 in fixing bar 2 lower end.Swivel nut 5 upper end open, lower end is provided with annular plug 14.Fixed block 6 is the cylinder of an inverted cone and is connected in the annular plug 14 bottom swivel nut 5.The afterbody of drift 4 is plugged in spliced eye 15, and the head of drift 4 stretches out outside swivel nut 5 through fixed block 6；The regulation cushion block 3 for regulating drift 4 inserting depth it is additionally provided with in spliced eye 15.Described lower mold 7 includes stripper 8, base 9, regulating block 10, block rubber 11.Base 9 is provided with forming cavity 12.Described stripper 8 is fixed on base 9, and stripper 8 is provided with guide hole 13 corresponding to the position of forming cavity 12.Regulating block 10 and block rubber 11 are arranged on base 9 inside and are positioned at immediately below forming cavity 12, and regulating block 10 is above block rubber 11.
Further, described stripper 8 one end is provided with installing hole 16, and the other end is provided with V-type groove 17, and described groove 17 opening direction is parallel with stripper 8 upper surface；Stripper 8 two ends penetrate being bolted on base 9 of groove 17 by a bolt penetrating installing hole 16 and one.So after workpiece cold-heading completes, somewhat loosen that root bolt of groove 17 correspondence, then pull that one end, groove 17 place of stripper 8, so that it may make stripper 8 rotate, make forming cavity 12 top limit and remove, in order to take out the workpiece that cold-heading is good.
Further, drift 4 and spliced eye 15 interference fits, drift 4 and fixed block 6 interference fit.It is stuck in workpiece preventing drift 4 from loosening, come off or preventing when upper mold 1 upwards puies forward back punching head 4.
During use, workpiece is loaded in the forming cavity 12 of base 9, then the drift 4 of upper mold 1 is directed at guide hole 13 and is pressed downward against interior six sides, during pressure down, the guide hole 13 of stripper 8 plays guide effect, make drift 4 can press to the required precision of parts warranties workpiece accurately, in workpiece completes cold-heading, block workpiece by stripper 8 after six sides not extract together with drift 4 simultaneously, then that one end, groove 17 place of stripper 8 is pulled, stripper 8 is made to rotate, make forming cavity 12 top limit to remove, part is finally made quickly to be taken out by forming cavity 12 top under the cooperation of regulating block 10 and block rubber 11, and can quickly place next part, the most again pull stripper 8, make stripper 8 rotate and make groove 11 be stuck on the bolt of its correspondence, just can reworking workpiece.Device of the present utility model not only substantially increases the efficiency of work pieces process and also assures that the required precision of part.
The utility model has the advantage of: reduce processing cost.Comparing with original cold-heading device, this device can be recycled and the workpiece of plurality of specifications can carry out six side's processing in cold-heading.Easy to operate, effectively improve working (machining) efficiency, reduce labor intensity.Location is reliable, and requirement on machining accuracy can be effectively ensured.Flexibly device can be adjusted according to the processing request of manufactured parts, improve its utilization rate.
