The speed of min at the uniform velocity moves down, and moves down cone-shaped end bar at the uniform velocity, obtains metal liquid stream.
Step 3, coagulation forming: adjusting vertical guide rod makes vertical distance between cylindrical coil and the top of sample to be prepared
For 10mm；It is powered to cylindrical coil, Overheating Treatment is carried out to molten metal stream with the power of 1kw, obtains over-heat metal liquid stream, is opened certainly
Autocontrol system moves guide plate along the x axis, connects object plate and moves along the y axis, while molten drop constantly falls into and connects object
Quick solidification after on plate, obtains the entity of bottom model, controls vertical guide rod and move along Z-direction, carries out second bottom model
The preparation of entity, in this way Layer by layer solidification from bottom to top, every layer, with a thickness of 0.1mm, finally obtains and three in automatic control system
The fine copper alloy three-dimensional part that D Data Model matches.
The shaping speed of fine copper alloy forming part prepared by this method is 0.08kg/min, and horizontal direction dimensional accuracy is missed
Difference is in<0.6mm, consistency>99.8% of sample.
As can be seen from the above embodiments, the alloy material that present device can be prepared is varied, applied widely, and
Fabricated part consistency is high, fully meets industrial requirement；The shaping speed that the present invention prepares product is significantly larger than laser gain material system
Technology is made, is thus substantially shorter the process time, and then reduce forming cost；The present invention directlys adopt alloy bar material as original
Material manufactures compared to the laser gain material for using powder material as raw material, can substantially reduce increasing material manufacturing cost, mention for increases material manufacturing technology
New method is supplied.
X-direction mentioned in the present invention is left and right directions, and Y direction is front-rear direction, and Z-direction is up and down direction；
The specification of raw bar material is diameter < 100mm, length < 1000mm in the present invention；Equipment of the invention can be according to sample to be prepared
The setting is placed in vacuum atmosphere or inert atmosphere or air atmosphere by property.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modification and variations of the invention belong to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
