26 rear portion of plate is connected with discharging cylinder 27, the stock guide 28 be oppositely arranged with discharging push plate 26 and by 10 appearance of lower die-sleeve towards
Outer extension；Two feeding limit plates 6 from two sides realize the blank 100 of feeding is limited, it is ensured that 100 axis of blank of feeding with
11 axis of cavity plate is overlapped, and guarantees the product quality of extrusion forming, and lifting push rod 14, which is realized, releases die cavity for finished product 200 after molding
16, and it is pushed out the present apparatus using discharging push plate 26 and stock guide 28, realize discharging.
As shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of extrusion forming of aluminum component stamping parts of technical solution of the present invention is filled
Setting the course of work is, firstly, molding blank 100 to be extruded is placed in die cavity 16.Start two feeding cylinders 5, so that on two
Material limit plate 6 positions blank from 100 two sides of blank, it is ensured that 100 axis of blank is overlapped with 16 axis of die cavity.Here a kind of
The blank of model corresponds to a set of feeding limit plate 6, and 6 side of feeding limit plate is set as the arc-shaped being adapted with stock side,
Realize that two side arc surfaces are positioned, rather than two o'clock or two lines are positioned so that positioning more by it is accurate.
Then, feeding limit plate 6 is withdrawn from, the press machine connecting with formed punch 8 is started, so that press machine drives formed punch 8 and peace
Cope plate 9 on formed punch 8 moves downward.First the conical portion of 8 front of formed punch realize to the progress of blank 100 downwards and
Extruding outward.After formed punch 8 passes through blank 100, formed punch 8 and 25 point column pressure head is contacted, and column pressure head 25 will be divided to be pressed downward,
It is divided to column pressure head 25 to realize to separate the two section mobile columns 21 that its underpart two sides are arranged in, two section mobile columns 21 are mobile to two sides respectively
And push limited post 20.After limited post 20 is moved fully in cylindrical hole 29, formed punch 8 is by dividing column pressure head 25 to push lifting column
13 move downward.At this point, formed punch 8 enters in bore of the punch 18, after the taper part before formed punch 8 is completely into bore of the punch 18, and
After the lower surface of cope plate 9 enters die cavity 16 and compresses finished product 200, and the shoulder of cope plate 9 is contacted with cavity plate 11, formed punch 8 stops
Only downwards, extrusion forming is completed at this time.Here limited post 20 is across cylindrical hole 29 and cross through hole in reset condition
23, it realizes the limit to lifting column 13, avoids 13 from moving downward under the pressure of blank, blank is avoided to become into bore of the punch 18
Shape guarantees the shape and quality of finished product 200.
Finally, resetting press machine and formed punch 8, start lifting cylinder 15, lifting cylinder 15 pushes lifting push rod 14 by finished product
200 release from die cavity 16, then drop finished product 200 under the action of discharging cylinder 27 and discharging push plate 26 and above push away from stock guide 28
Out, discharging is completed.
Technical solution of the present invention is exemplarily described invention above in conjunction with attached drawing, it is clear that present invention specific implementation
It is not subject to the restrictions described above, changes as long as using the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out
Into, or it is not improved the conception and technical scheme of invention are directly applied into other occasions, in protection scope of the present invention
Within.
