Description
Technical field
The invention belongs to train wheel processing technology field, more particularly, relate to a kind of train wheel and produce the comprehensive pressure machine.
Background technology
China's train wheel production has had the history in more than 50 year till now since 1964, its production technology belongs to four unit production technologies." four units " refers to that the main nucleus equipment of this production line is comprised of upsetting press, forming press, mill for rolling center disctype wheels, press-bending puncturing machine, its technological process is: the steel billet that heats carries out jumping-up, impression through sending into upsetting press behind the dephosphorize by high pressure water, and then send into forming press and carry out forging forming, the blank of forging forming is sent into mill for rolling center disctype wheels and is rolled, and rolling good blank is sent into the punching of bending of press-bending puncturing machine again.
In August, 2000, the l7 volume, the 34th page of " steel rolling " of the 4th phase discloses one piece of name and has been called " technological transformation of horse steel train wheel production system " (author: Zhang Gaoping, Wu Licang, document Liu Huiqiang), point out that wherein Ma Gang carries out after the new technology transformation wheel knowhow and the international standard requirement with reference to industrially developed country, adopt process for machining after the first heat treatment, technique is: and steel ingot cutting → heating → 30MN hydraulic press pier is thick → and 80MN hydraulic press moulding → horizontal wheel mill milling → 30MN hydraulic press bends, punching, printing → isothermal → quenching → tempering → performance checking → ball blast de-scaling → semi-finished product dimensional gaughing → machined → cold typewriting → ultrasonic examination → magnetic powder inspection → ball blast (reinforcement disc) → static balancing test
→Bore boring oil filler point → finished product (size and hardness) inspection → oiling, the packing → steps such as warehouse-in.Technique before improving is: steel ingot cutting → heating → 30MN hydraulic press pier slightly → 80MN hydraulic press moulding → horizontal wheel mill milling → 30MN hydraulic press press-bending, punching, printing → isothermal → quenching → tempering → inspection → warehouse-in.
In the 5th phase in 2003 " forging technology ", the document that one piece of name is called " train wheel Research of Forming Technology and finite element modelling " (author Guo Xiaoxia) is disclosed, second portion is pointed out about the description of train wheel forming technology in the literary composition, at present, the wheel manufacturing process mainly contains casting, full die forging and forges rolling both at home and abroad.Forge rolling and claim again the pressure rolling method, be widely applied all over the world.Its production comprises that heating steel billet, jumping-up, preform, wheel hub punching, former bend, rectification, heat treatment, machined, wheel detection and the test etc. of wheel geometry size.The wheel blank crushed element is generally finished with some hydraulic presses and a chaptrel milling train, and its heat forming technology is:
(1) to steel billet segmentation blanking, at the cake blank that behind dephosphorize by high pressure water, is upset as certain altitude on the hydraulic die press;
(2) utilize piece pre-forming die at 60MN pull-down hydraulic die press, blank is carried out the processing of preform work step, shaping wheel hub and wheel rim and part former thickness;
(3) carry out punching with 10MN double action punching hydraulic press;
(4) on the horizontal milling train of seven rollers to the spoke roll off, make the diameter that radially reaches hot forging of wheel rim, the thickness of spoke reduces, tread is shaped;
(5) with the crooked former of 30MN double-action drawing press-bending hydraulic press, make it to meet the requirements of thickness, and make wheel shape obtain proofreading and correct.
More than two pieces of documents confirmed that all jumping-up, impression (being also referred to as moulding) they all are to need respectively two forcing presses in the existing train wheel production technology both domestic and external, so carry out needing to dispose three forcing presses on the forging forming production line.The price comparison of forcing press is expensive, and the production cost of enterprise is high, carries out if jumping-up, indentation process can be incorporated on the forcing press, will save a forcing press, reduces greatly the production cost of enterprise.But being, its Major Difficulties finishes jumping-up, impression at a forcing press, utilizing so existing forcing press can only be to adopt forming press, but jumping-up on forming press, its performance accuracy are difficult to guarantee that eccentric possibility appears in compacting blank out have been increased greatly.How solving precision problem is key point.In addition, finishing jumping-up, impression at a forcing press needs the forcing press function to increase, and the operation of forcing press is also more difficult.
Summary of the invention
The technical problem that invention will solve
In existing train wheel production technology, need three forcing presses, the problem that production cost is high, the invention provides a kind of train wheel and produce the comprehensive pressure machine, it can finish jumping-up, indentation process at a machine, so that reduce by a forcing press in the train wheel production process, reduce production costs.
