Abstract
The utility model relates to the technical field of electromagnetic forming test devices, in particular to a novel elastic medium electromagnetic direct induction forming tool. A lower base plate is arranged at the bottom inside a die frame, the upper end of the lower base plate is connected with a die seat, a concave die is arranged on the die seat, an elastic medium is arranged on the upper portion of the concave die, the upper end of the elastic medium is connected with a coil through a drive sheet, the coil is connected with an upper base plate, and the upper base plate is arranged at the top end of the inner side of the die frame. Paired rigid dies are not needed based on the electromagnetic forming technology, the die tool is simple, machining is easy, cost is low, and the manufacturing period is short. The tool formed through the pressure transmitting medium should be adopted for sheets which are poor in electrical conductivity or are good in electrical conductivity and have the blank thickness smaller than the penetration depth of a magnetic field, product part precision is high, freezing performance is good, elastic reset deformation is small, and the quite good effect is achieved.
Description
Technical field
The utility model relates to electro-magnetic forming experimental rig technical field, refers in particular to a kind of novel elastic medium electromagnetism and directly responds to fixture for forming.
Background technology
Rupture disk is one of superpressure preventing safety attachment of pressure vessel and pipeline and other pressurized obturators and equipment, and its effect is equivalent to the fuse on electric equipment.Rupture disk is thin plate manufacture, and size can be that the several millimeters of diameter arrive hundreds of millimeter, and traditional process for stamping is gas pressure compacting or hydroforming, is difficult to guarantee its quality and performance requirement.Utilize Electro Magnetic Forming technology to be shaped and not only can obtain good product, can also realize good economic benefit.Bad for electric conductivity, though or the good sotck thinkness of the electric conductivity thin plate material that is less than the magnetic field penetration degree of depth adopt the Mould Machining difficulty of existing electro-magnetic forming, the manufacturing cycle is long, structural design is reasonable not, has affected the production of rupture disk.
Therefore, for overcome the deficiency of above-mentioned technology design for electric conductivity bad, though or the good sotck thinkness of the electric conductivity thin plate material that is less than the magnetic field penetration degree of depth process, mold tooling is simple, handling ease, cost is low, the manufacturing cycle is short; Product parts precision is high, and the property freezed is good, and spring-go is out of shape little a kind of novel elastic medium electromagnetism and directly responds to fixture for forming, inventor's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel elastic medium electromagnetism and directly responds to fixture for forming, it is simple in structure, easy to use, bad for electric conductivity, though or the good sotck thinkness of the electric conductivity thin plate material that is less than the magnetic field penetration degree of depth have extraordinary processing effect, mold tooling is simple, handling ease, cost is low, and the manufacturing cycle is short; Product parts precision is high, and the property freezed is good, and spring-go distortion is little, has extraordinary practical value.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel elastic medium electromagnetism is directly responded to fixture for forming, it is characterized in that: frock comprises mould bases, upper padding plate, coil, driving chip, elastic fluid, die, die holder, lower bolster, lower bolster is arranged on mould bases inside bottom, lower bolster upper end is connected with die holder, on die holder, be provided with die, die top is provided with elastic fluid, elastic fluid upper end is connected with coil by driving chip, coil is connected with upper padding plate, and upper padding plate is arranged on top inside mould bases.
The utility model is compared and is had obvious advantage and beneficial effect in prior art, particularly, and as shown from the above technical solution:
1, the logical Electro Magnetic Forming technology of the utility model does not need paired rigid die, and mold tooling is simple, handling ease, and cost is low, and the manufacturing cycle is short; Bad for electric conductivity, though or the good sotck thinkness of electric conductivity be less than the thin plate material of the magnetic field penetration degree of depth, the frock that should adopt the utility model to utilize transmission medium to be shaped, product parts precision is high, the property freezed is good, spring-go distortion is little, has extraordinary effect.
Accompanying drawing explanation

Accompanying drawing explanation: 1-mould bases; 2-upper padding plate; 3-coil; 4-driving chip; 5-elastic fluid; 6-stock; 7-die; 8-die holder; 9-lower bolster.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is that a kind of novel elastic medium of the utility model electromagnetism is directly responded to fixture for forming structural representation, frock comprises mould bases 1, upper padding plate 2, coil 3, driving chip 4, elastic fluid 5, die 7, die holder 8, lower bolster 9, lower bolster 9 is arranged on mould bases 1 inside bottom, lower bolster 9 upper ends are connected with die holder 8, on die holder 8, be provided with die 7, die 7 tops are provided with elastic fluid 5, elastic fluid 5 upper ends are connected with coil 3 by driving chip 4, coil 3 is connected with upper padding plate 2, and upper padding plate 2 is arranged on mould bases 1 top, inner side.
The utility model is waited in use, utilizes driving chip 4, elastic fluid 5, magnetic field energy is passed to blank 6, realize and paste contour formings by die 7, bad for electric conductivity, though or the good sotck thinkness of electric conductivity be less than the thin plate material of the magnetic field penetration degree of depth, the utility model has increased driving chip 4, elastic fluid 5, the frock of utilizing transmission medium to be shaped, product parts precision is high, and the property freezed is good, spring-go distortion is little, has extraordinary effect.
