Description
Technical field
The utility model relates to the technical field of metal forging crackle control.
Background technology
Conventionally forging is used as shown in Figure 1, and it is made up of the identical upper flat anvil 1 of shape and lower flat anvil 2, to carrying out forging molding processing at this common flat anvil after bar or sheet material heating; But because the plasticity of metal is poor, resistance of deformation is large, the metal material of strain hardening and strain-rate sensitivity and narrow forging temperature, simultaneously because viscosity is large, poor fluidity, malleability is quite low, can be because being out of shape wayward and alloy plasticity is poor in flat-anvils stretching forges, cause the formation of forge crack and forging polishing misrun seriously or is directly scrapped, percent defective is high, and production efficiency is lower.This will increase forging cost virtually, and production efficiency reduces.
Utility model content
Technical problem to be solved in the utility model is: avoid metal forging crackle in flat-anvils stretching forging stock process because deflection is wayward, stress is concentrated, cause the formation of forge crack and make forging polishing misrun seriously or directly scrap problem, cause product percent of pass lower, forge the high problem of cost.
The technical solution of the utility model is: a kind of swage block that prevents metal forging crackle, comprise laterally zygomorphic upper swage block 1 and lower swage block 2, the V-type groove 3 of more than one different size is set on the lower surface of upper swage block 1, the dimensions of V-type groove 3 size and shape required with the forging process of forging is corresponding, and V-type groove 3 carries out chamfered with the intersection of lower plane and the drift angle place of V-type groove.The number of described V-type groove 3 is determined by the required size of the forging process of forging.Described chamfer dimesion is determined by V-type groove size and forging deflection.
Described upper swage block 1 and lower swage block 2 adopt mould steel, preferably adopt the affiliated 5CrNiMo mould steel of Cr-Ni-Mo steel series die.
The beneficial effects of the utility model are: on the basis at original forging flat anvil, by prefabricated laterally zygomorphic upper swage block 1 and the lower swage block 2 of comprising, the V-type groove 3 of more than one different size is set on the lower surface of upper swage block 1, the dimensions of V-type groove 3 size and shape required with the forging process of forging is corresponding, and V-type groove 3 carries out chamfered with the intersection of lower plane and the drift angle place of V-type groove.The number of described V-type groove 3 is determined by the required size of the forging process of forging.Described chamfer dimesion is determined by V-type groove size and forging deflection.
Adopt the method to forge and solved forge crack and size Control problem, improved forging quality, qualification rate and forged the problems such as cost.

Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail
It is that in Mg-Zn-Zr system, plasticity magnesium alloy manufacture of materials is that example illustrates that the part of certain type machine is prepared required forging MB15 alloy, its shape is made up of the square-section of three sections of different sizes, sectional dimension is respectively 90mm, 80mm, 70mm, and length dimension is respectively the axle type free forging of three steps of 130mm, 115mm, 100mm.
Because of the MB15 alloy to forging rate sensitivity, resistance of deformation is large, very responsive to rate of deformation and hammering weight while forging on hammer, while forging with flat anvil, flat process rate of deformation is slightly fast or hammering is slightly heavy may occur the large crackle of penetrability in forging stock two ends clapping, when pulling because edges and corners temperature is scattered and disappeared very fast, side corner angle are prone to large crackle, when occurring must stopping after crackle to forge, after row's wound, reheat forging stock, often forging stock seriously can not meet the demands and scrap because of polishing misrun.And the forging method of special V font swage block for employing the utility model: first by prefabricated laterally zygomorphic upper swage block 1 and the lower swage block 2 of comprising of 5CrNiMo mould steel, the V-type groove 3 of 3 different sizes is set on the lower surface of upper swage block 1, the dimensions of V-type groove 3 size required with the forging cross section of forging is corresponding, and V-type groove 3 carries out with the intersection of lower plane and the drift angle place of V-type groove that chamfering is distributed as R20, R15, R10 and R15, R10, R8 process.Described chamfer dimesion is determined by V-type groove size catercorner length 130mm, 115mm, 100mm and forging deflection 30%～35%.
Above-mentioned upper swage block and lower swage block are preheated to 250 DEG C of left and right with heat material, then by after 400 ± 10 DEG C × 280min of MB15 magnesium alloy rod heating of diameter 110mm, long 288mm, raw material bar is put into the die cavity that Diagonal Dimension is 130mm, forge 90 × L to by applicable forging frequency, forging equipment is 2t electricity liquid hammer; Then middle forging stock is taken out and melted down after heating 135min, then to put into Diagonal Dimension be that the die cavity of 115mm pulls out 80 × L to; Again middle forging stock is taken out and melt down after heating 120min, carry out after suitable sub-material again, the die cavity of first a termination being put into Diagonal Dimension and be 100mm pulls out to the size of 70 × L, again symmetry operation is carried out in another termination, there is crackle in above-mentioned fire time middle contingency, after the row's of polishing wound, proceed next fire; Finally by the extremely required waste type of arc of special bending swage block forging and stamping shaping for the forging stock after pulling.
Technological requirement completes relevant forging process on flat-die hammer, but common flat anvil cannot ensure the requirement for crackle control in the open die forging pulling of this material at all, causes producing and can not normally complete.If with the V-type anvil of this invention, can complete smoothly production task.
By once forging in 3 different size type grooves on V-type anvil to bar, mobile, the operations such as reversion realize sizes control and the crackle prevention of forging on forging hammer, constraint by V-type anvil to forging process for fuel stress and the variation of size Control, change the point of application and the application of force direction of stress to forging, solve the different cross section dimensional requirement problem of forge crack problem and forging requirement, complete the translation on the forging hammer of these 3 kinds of sectional dimensions, upset, the complex operations such as chamfering, thereby avoid the generation of forge crack, meet open die forging and produced this forging middle section size Control, pulling, frock replacements etc. are to requiring.
Adopt this V-type anvil to produce the forging of step circle or square-section, can reduce the O&M of the replacing process of the swage block of different shaped groove in production process, reduce the cost of forging molding processing.
