Abstract
The invention relates to a method for stamping magnesium alloy in a cold state. The method is characterized in that the magnesium alloy in a cold state is blanked by a stamping die, a blanking gap Z ranges from 0.5% of delta to 7.0% of delta, and the delta refers to the thickness of a material. The blanking gap is reasonably set at the room temperature, a section effect of precision stamping process can be obtained by the common stamping method, the brightness of the stamped section of a magnesium alloy plate can reach 90% at least and is higher than that of the stamped section of an existing magnesium alloy plate formed by means of conventional stamping process in the prior art by 20%, dressing of the section of a blanked part after the magnesium alloy is stamped in the cold is omitted, accordingly, production efficiency is high, production cost is low, technological applicability of the magnesium alloy is improved, and conditions for expanding application of the magnesium alloy are created.
Description
Technical field
The present invention relates to a kind of magnesium alloy cold conditions process for stamping.
Background technology
The proportion of magnesium is 1.74g/cm
3, have only aluminium 2/3, titanium 2/5, steel 1/4; Magnesium alloy is lighter by 36% than aluminium alloy, lighter by 73%, lighter by 77% than steel than kirsite.Magnesium alloy is the lightest structural metallic materials, has become the environmental protection engineering material that the world attracts people's attention most, has broad application prospects.
At present, magnesium alloy is a foundry goods as the maximum of structure applications, and ratio reaches more than 90%.Though main cause is the existing very big progress of the research of magnesium alloy punched technology, also there is a big difference with production application.Because the magnesium alloy crystal is a close-packed hexagonal structure; Its plasticity under cold conditions is relatively poor, belongs to fragile material, with traditional Sheet Metal Forming Technology parameter magnesium alloy plate is carried out punch process; The euphotic belt of its section is no more than 20%, and this state can't satisfy the instructions for use of most of pressed parts.Need under heated condition, process aborning, perhaps need rebuild processing to the blanking part section after the cold conditions punching press and just can meet the demands, so production efficiency be lower, production cost is high.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of euphotic belt width up to the thick magnesium alloy cold conditions process for stamping more than 90% of material.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of magnesium alloy cold conditions process for stamping is provided, utilizes diel that the magnesium alloy of cold conditions is carried out stamping-out, and blade clearance Z=0.5% δ～7.0% δ, δ is thick for material.
Wherein, said diel comprises punch and die, and said punch is the plano-convex mould.
Wherein, said blade clearance Z=0.5% δ～3.0% δ.
Wherein, said sheet thickness δ is 3-6mm, shears surplus >=2mm.
Wherein, said plate model is AZ21X, AZ31X or AM50.
The magnesium alloy of cold conditions described in the present invention is meant magnesium alloy at room temperature, that do not do the heating and cooling processing.
The invention has the beneficial effects as follows: because magnesium alloy cold conditions process for stamping of the present invention is at room temperature through rationally being provided with the blade clearance; Adopt the method for common punching press, just can obtain the section effect of precision stamping technology, the punching press section euphotic belt of magnesium alloy plate is reached more than 90%; Substantially exceed that the high energy of conventional Sheet Metal Forming Technology reaches in the prior art 20%; Do not need after the cold conditions punching press blanking part section is rebuild processing, so production efficiency is higher, production cost is low; Improve the technology applicability of magnesium alloy, for the expanding application of magnesium alloy has been created condition.

The specific embodiment
By specifying technology contents of the present invention, structural feature, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
Embodiment as magnesium alloy cold conditions process for stamping of the present invention; See also Fig. 1 and Fig. 2; Magnesium alloy cold conditions process for stamping is to utilize diel that the magnesium alloy 3 of cold conditions is carried out stamping-out, and diel comprises punch 1 and die 2; Blade clearance Z=0.5% δ～7.0% δ, δ are that the material of magnesium alloy 3 is thick.
According to the stamping-out basic principle and the condition of palsticity; Change the stress state of plate when cutting off through changing parameters such as mould blade clearance Z, punch blade angle α, excision amount L; The fracture mode of plate is different under the different stress, and then obtains different section states.Because magnesium alloy plasticity is relatively poor, when punch during to incision, also not switching to the end will rupture; Because the direction of crack propagation of magnesium alloy section is different with common plastic material, the crackle of magnesium alloy shows the seminess of outwards protruding from the punch cutting edge again, and this is a very large new discovery; Like this; When punch continues when descending, punch will be rebuild section, so under a stamping-out stroke; Accomplished punching and trimming two procedures, thereby made section reach the requirement of wide euphotic belt.
See also accompanying drawing 2, through change plate when the punching stress so that change the crackle height h1 and the height h2 that subsides.H1 helps trimming when one desired value is arranged, the then more little area that can rebuild of h2 is big more, and then the light face is bigger more than regular meeting after the punching.When blade clearance Z=0.5% δ～7.0% δ, the section euphotic belt reaches more than 90%.
Embodiment one: following is that 5.7mm, width are that the AZ21X magnesium alloy billot of 15mm carries out punching press to select sheet thickness δ for use; Shear surplus >=5mm; Adopt process for stamping of the present invention; Punch adopts plano-convex mould (be α=0 °), adopts the method processing of not smoothing after thrusting can get euphotic belt width such as following table:
| The blade clearance | ?0.5％δ | 1.5％δ | 3.0％δ | 4.5％δ | 6.0％δ | 7.0％δ |
| Euphotic belt width (%) | ?96 | 95 | 94 | 93 | 92 | 91 |
Embodiment two: be that 3mm, width are that the AZ21X magnesium alloy billot of 15mm carries out punching press to select sheet thickness δ for use again; Shear surplus >=5mm; Adopt process for stamping of the present invention, punch adopts plano-convex mould (be α=0 °), adopts the method processing of not smoothing after thrusting can get euphotic belt width such as following table:
| The blade clearance | ?0.5％δ | 1.5％δ | 3.0％δ | 4.5％δ | 6.0％δ | 7.0％δ |
| Euphotic belt width (%) | ?96 | 96 | 95 | 93 | 92 | 91 |
