Description
Technical field
The invention belongs to metal material increases material manufacturing technology field, more specifically to a kind of based on electroslag remelting
Increasing material manufacturing device, suitable for the manufacture of hot-work die, cold-working mould and other stamped metal parts.
Background technology
Increasing material manufacturing (3D printing) technology as a kind of RP technique rapidly change people the mode of production and
The developed countries such as life style, America and Europe and emerging economies country are one after another as strategic emerging industries.
Metal increases material manufacturing technology is generally regarded as the leading edge developments direction of increases material manufacturing technology field most difficulty, is pressed
Heat source can be divided into 3 class of laser, electron beam and electric arc.Past mainly research using laser, electron beam as heat source powder Base Metal
Increases material manufacturing technology, such as：Laser near-net-shape technology LENS, selective laser melt SLM, laser melts deposition LMD etc.[1-3],
By constantly melting or sintered metal powders continuously successively prepare labyrinth parts, applied to aerospace, national defence
The high-grade, precision and advanced preamble key components and parts such as military project, but its shaping rate is slow, and equipment is expensive, and powder based raw material manufacturing cost
It is excessive with use cost[4].Therefore, certain limitation is shown during existing technology shaping large scale complex structural member, and base
The low cost that grows up in technique for overlaying, high efficiency electric arc increases material manufacturing technology WAAM are subject to some scholars to pay close attention to.
WAAM manufactures metal solid component using electric arc as beam is carried by the way of product is successively melted.Compared to laser, electron beam
Increasing material manufacturing, the material scope of application is wider, and forming efficiency is high, and cost is low, and dense structure, be adapted to large-size components it is low into
Originally, efficient quick near-net-shape[5-7].Wang Guilan etc. increases material shaping new method with the micro- casting of electric arc and produces 45 steel high intensity zero
Part, with respect to 45 steel forgings, the micro- rolling casting bonding drip molding hardness of electric arc improves 25.9%, and tensile strength improves 43.3%, elongation
Improve 5.9%[8].Ouyang et al. researchs point out that influence forming dimension precision, the key point of surface quality are arc length, substrate
The accurate control of preheating temperature and interlayer temperature[9].Almeida et al. studies the deposition forming technique of titanium alloy, profit
The power " source " disturbed with magnetic control stabilising arc technical controlling heat input and molten bath, obtains the higher thin-wall member of surface quality[10].English
State Cranfield university research people systems, which have studied the parameters such as weldering speed, wire feed rate, gage of wire, WAAM shaping patterns
The affecting laws such as width, surface wave are imitated, different angle degree is realized and closes the increasing material shaping of thin-wall part[11]。
Also there are related patents to disclose on electric arc increases material manufacturing technology WAAM in the prior art, such as patent publication No.：CN
106312069 A, publication date：On 01 11st, 2017, invention and created name was：A kind of molten bath control method of increasing material manufacturing,
This application discloses the molten bath control technology that a kind of electric arc increases the material method of forming and fusion sediment increasing material manufacturing method, its key is
An outline border or profile that can be limited molten metal and flow is built in melt tank edge using other materials, utilizes the table of liquid in itself
Face tension force and the repulsion to other materials, constrain the flowing of liquid metal.When carrying out the shaping of metal material, pacify on workbench
The shock module of dress, which can carry out molten bath vibrations, makes liquid metal uniformly to be spread out in the region constrained by profile.But should
Application case is disadvantageous in that：For electric arc increases material manufacturing technology WAAM relative to conventional metallurgical manufacturing process, efficiency does not have still can
Degree of purity than property, and product is completely dependent on the degree of purity of silk material, and silk material manufacture craft is also complex, limits drip molding
Development of the material to high-quality and diversity direction.
