Abstract
Box car inner riveting type lantern ring forming method and mold.Lantern ring is made of the flange of sleeve and interior aperture by interior macropore.Using processes such as blank, 15 station cold-headings, punchings.12 stations are smooth to cold-heading blank both ends of the surface and cold-heading goes out upper and lower chamfering male cone (strobilus masculinus).Three stations to five station cold-headings are from forming flange, sleeve blank, preexisting hole to shaped flange, sleeve and interior three hole.Punching excludes three endoporus waste materials and covers ring forming.Three to five station dies, which have, rushes the dynamic upper tube of core ribbon, can make to block product when reset and move back upwards, be ejected product directly or by thimble and outer ejector sleeve by lower section thimble.Existing turnery processing is substituted with cold-heading, product strength is high；Each stock volume reduces 3 times, and stock utilization improves 3 times, and material utilization amount falls to 1/3.Cold-heading blank is processed on the cold header of six station dies equipped with automatic operating clamp, and at least cold-heading in 1 minute goes out 30 products, and 1 product of existing turnery processing at least wants 5 minutes, and efficiency improves 150 times or more.It can be used for box car inner riveting type lantern ring.
Description
(1) technical field：The present invention relates to a kind of pulling rivet lantern ring cold-heading material molding technologies, belong to connector class
(E06B) and the forging class of metal (B21J).
(2) background technology：
The shape of the inner riveting type pulling rivet lantern ring finished product 7 of box car (lorry) is shown in Fig. 7 and Fig. 8, and lantern ring finished product is by covering
Cylinder 7B and flange 7A (also known as covering take capel) compositions.Sleeve 7B includes two sections:Endoporus be macropore 7.2 book wall cylinder crotch section with
And the locking section composition for the thick cyclinder that endoporus is aperture 7.1.(refer to Chinese invention patent<Detachable locking riveting dismounting
Method and pulling rivet>Patent No. ZL201410650279.8).Flange endoporus is also aperture 7.1, herein referred as aperture in flange
7.1, macropore 7.2 is herein referred as macropore 7.2 in sleeve, is unthreaded hole.
Traditional box car mainly uses turning with inner riveting type pulling rivet lantern ring forming method.See Fig. 7, provides one piece first
Turning blank 8 (see dotted line in Fig. 7), size is:Turning blank outer diameter Φ 8=lantern ring flange outer diameter Φ A+ outer diameter turnery processings
Amount.Turning blank height H8=lantern rings overall length+overall length turnery processing amount, lantern ring overall length=H7A+H7B.General flange outer diameter Φ A
It is 3-4 times of sleeve outer diameter Φ B, so there are following points using turnery processing:1) utilization rate of raw materials is low, production efficiency
It is low, cause of high cost:Because flange and sleeve diameter gap are big, a large amount of material is consumed, and again because processing capacity also causes to imitate greatly
Rate is low.2) low with the intensity of product after turning in turning.
(3) invention content
Box car provided by the invention inner riveting type lantern ring production method and mold exactly solve traditional box car and are drawn with inner riveting type
