The upper and lower arc anvil combined tool comprises an upper arc anvil combined part and a lower arc anvil combined part, and is of an upper arc-shaped and lower arc-shaped structure connected by spring seat guide pins, positioning pins and high-strength springs. The upper and lower arc anvil combined tool has the advantages that by designing upper and lower arc anvils in specifications with diameter larger than phi 450mm for producing large shaft type forged parts, production material cost is reduced, machining allowance is decreased, and the upper and lower arc anvil combined tool has considerable economic benefits and promising market prospect; by specially designing upper and lower spring seats and a lower anvil seat, actual production and demounting are more convenient and flexible and higher in efficiency, service life is longer and more importantly, the upper and lower arc anvils are applied in medium and large hydraulic presses more than 2500 in tons.
Description
Technical field
The utility model relates to a kind of good in order to 2500 tons of above large-scale dydraulic forging moulding large axis forgings and forging roundness, axle class upper and lower arc anvil frock forging molding for for the little large-scale hydraulic press of machine-finish allowance, tooling device field is used in the manufacture of genus large axis forging.
Background technology
1, CN202555754U, title " arc anvil ", it comprises two arc anvil bodies, arc anvil body comprises coattail strip, support section and working portion, coattail strip is arranged at the bottom of support section, working portion is arranged at the top of support section, the end face of working portion is to the recessed cambered surface of just working, and a side of working portion is the side work cambered surface concaving; The central angle of the cambered surface of just working is less than or equal to 180 °, and the central angle of side work cambered surface is less than or equal to 90 °; Two arc anvil bodies are opposed in vertical direction.See accompanying drawing 7.Its weak point: be only suitable for the small-sized forging enterprise in the following optical axis forging of professional production ￠ 400mm, and this arc anvil is for forging hammer, is fixed on anvil block, be inconvenient to load and unload, for also inapplicable on press.
2, in current forging industry, use upper and lower arc anvil to produce the producer of forged shaft, be mostly on forging hammer equipment or having 1600 tons of miniature water press or forging soon in the enterprise of formula hydraulic press and use, and the arc anvil specification using is all below ￠ 400mm～￠ 450mm.Meanwhile, upper arc anvil and lower arc anvil are made by steel plate fixingly utilizes both sides that the operation principle that dual spring is realized is installed respectively with Triangulum, not only service life short, and often need to change spring.For having 2500 tons with forging enterprise upper, large-scale hydraulic press, if adopt traditional upper and lower arc anvil to produce large axis forging, roundness is poor often for the product of not only manufacturing, and machine-finish allowance is large, waste of material is large, and cannot use.
Utility model content
Purpose of design: avoid the weak point in background technology, design one can be used on hydraulic press more than 2500 tons, dimensions, more than ￠ 450mm, has again long service life, the large-scale hydraulic press use axle class of flexible and convenient operation upper and lower arc anvil frock for forging molding.
Design: in order to realize above-mentioned purpose of design.The application's key is to solve the no longer simple upper and lower flat-anvils stretching that passes through of the above major diameter forged shaft of ￠ 450mm and produces, and makes product machine-finish allowance large, the problem that cylindrical roundness is inadequate.Design one can make the above forged shaft of ￠ 450mm produce by upper and lower arc anvil pulling with upper, large-scale hydraulic press at 2500 tons, better controls machine-finish allowance and circle product external roundness.The application is in structural design, 1, adopt and make the fixing Triangulum of using that upper and lower spring base forging has replaced steel plate to make, the object of design is like this: spring base forging is more firm than steel plate Triangulum, the pressure can bear is larger, particularly on large press, produce large axis forging and need not often change spring base, but steel plate Triangulum is not accomplished.2, the object that under design specialized, anvil block connects upper and lower arc anvil is: when forging large axis forging and forging other products, can not conflict, if need to use upper and lower flat anvil to forge time, only need lower anvil block and upper and lower arc anvil Integral lifting to go out workspace, rational in infrastructure, handling are flexible, greatly save the time of changing frock.
Technical scheme: a kind of large-scale hydraulic press use forged shaft upper and lower arc anvil for forging molding, it comprises arc anvil body and lower arc anvil body, lower anvil block is groove shape structure and lower arc anvil body bottom and is positioned at the groove of lower anvil block, upper arc anvil body and lower arc anvil body, be connected and go to upper and lower arc overall structure with alignment pin and high-strength spring by spring base guide pillar.
The utility model is compared with background technology, the one, the upper and lower arc anvil of the above major diameter specification of design ￠ 450mm is for the production of large axis forging, both reduce production material cost, reduced again machine-finish allowance, there are extremely considerable economic benefit and market prospects; The 2nd, designed special upper and lower spring base, make actual production more convenient operation flexible, efficiency is higher, longer service life, the more important thing is realized upper and lower arc anvil at 2500 tons with the application on upper, large-scale hydraulic press.
