The multicomponent composite tungsten electrode is produced with tungsten bar blank after being swaged in the B203 stage, and through three swage steps in the B202 stage, including the first one from 6.0 mm to 5.6 mm at 1450-1500 deg.c, the second one from 5.2 mm to 4.8 mm at 1400-1450 deg.c and the third one from 4.4 mm to 4.1 mm at 1400-1450 deg.c; and the two swage steps in the B201 stage, including the first one from 3.9 mm to 3.6 mm at 1400-1450 deg.c and the second one from 3.3 mm to 3.0 mm at 1350-1400 deg.c, to obtain the multicomponent composite tungsten electrode. The present invention has simplified production process, high production efficiency and low power consumption.
Description
Technical field
Swaging apparatus and process for multicomponent composite tungsten electrode belongs to rare earth refractory metal material manufacture field.
Technical background
Tungsten, molybdenum and other refractory metals poor in processability, thereby usually adopt the processing mode of swaging had both been revolved hammer and done radially reciprocating motion in rotation at a high speed, thereby made the homogeneous deformation of base bar.For the processing of tungsten and tungsten alloy, it is normal that what adopt is that singly the swage equipment of swaging of head is processed, in the original application patent (200710099090.4), promptly adopt the swager of this unit head for the disconnected processing of revolving of multiplex composite rare-earth tungsten electrode, electrode material of multielement composite rare earth tungsten need be through 6 procedures in the B202 stage, need be in the B201 stage through 4 procedures, complex procedures, labour intensity is big, for improving working (machining) efficiency, revolving the hammer machine with two, to constitute jointly that a cover string sets be an effective way fully, had similar devices to be used for the molybdenum materials manufacture field at present, and for tungsten, particularly rare earth doped tungsten material, do not have this type of Special Equipment to use at present, this mainly be since the processability of tungsten than molybdenum difference, particularly rare earth doped after, the rare earth second phase particle changes the crisp transition temperature of moulding of tungsten material to the influence of material structure, thereby do manual work for the skill for string, except that requiring the charging rate unanimity, it is also particularly important to join the system of touching and processing temperature.
Summary of the invention
At above technical problem, main purpose of the present invention is exactly the mechanical property that adapts to electrode material of multielement composite rare earth tungsten, adopt the string technology of beating to realize tungsten material highly-efficient processing, the present invention adopts by two same models, same frequency, with the swager (B201-B201 of speed, B202-B202) string of Zu Chenging sets the B202 that carries out electrode material of multielement composite rare earth tungsten fully, the processing in B201 stage is characterized in that:
(1) at first first heating furnace, 1, the second heating furnace 4 is warmed up to 1450～1500 ℃, the diameter after will swaging through B203 then is that the electrode material of multielement composite rare earth tungsten of Φ 6.5 is sent into 2～3m/min speed and revolved hammer string and set and begin processing fully;
(2) need be in the B202 stage through the processing of three passages, process system is:
First road: first revolves hammer machine 2 apolegamy Φ 6.0 moulds; Second revolves hammer machine 5 apolegamy Φ 5.6 moulds; First heating furnace 1, second heating furnace, 4 temperature are set to: 1450～1500 ℃;
Second road: first revolves hammer machine 2 apolegamy Φ 5.2 moulds; Second revolves hammer machine 5 apolegamy Φ 4.8 moulds; First heating furnace 1, second heating furnace, 4 temperature are set to: 1400～1450 ℃;
The 3rd road: first revolves hammer machine 2 apolegamy Φ 4.4 moulds; Second revolves hammer machine 5 apolegamy Φ 4.1 moulds; First heating furnace 1, second heating furnace, 4 temperature are set to: 1400～1450 ℃;
(3) process through two passages in the B201 stage, its process system is:
First road: first revolves hammer machine 2 apolegamy Φ 3.9 moulds; Second revolves hammer machine 5 apolegamy Φ 3.6 moulds; First heating furnace 1, second heating furnace, 4 temperature are set to: 1400～1450 ℃;
Second road: first revolves hammer machine 2 apolegamy Φ 3.3 moulds; Second revolves hammer machine 5 apolegamy Φ 3.0 moulds; First heating furnace 1, second heating furnace, 4 temperature are set to: 1350～1400 ℃;
Can obtain the electrode material of multielement composite rare earth tungsten of Φ 6-Φ 3 by above processing.。
The B203 that is mentioned in the above-mentioned steps, B202, B201 are the common process process in the tungsten processing, are generally used for segmenting rotary swaging process, are meant the processing of swaging of adopting B-203, B-202, B-201 swager to carry out.B-203, B-202, B-201 are the unit type of swager, and the stroke maximum is hammered in revolving of B-203 swager into shape, the big workpiece of suitable processing; The hammer stroke that revolves of B-202 swager takes second place, suitable processing small workpiece; The stroke minimum is hammered in revolving of B-203 swager into shape, generally is used for processing littler workpiece.Die change system Φ 6 grades that above-mentioned steps is mentioned are meant that the minimum machining diameter of touching of swaging is 6mm.
This apparatus and process laid down by is to formulate according to the Changing Pattern of organizing of electrode material of multielement composite rare earth tungsten, the Deformation structure of electrode material changes in the process, recovery temperature and recrystallization temperature also change according to deformation extent, therefore for avoiding electrode material of multielement composite rare earth tungsten that crystallization embrittlement phenomenon again takes place, also need to change processing temperature it is remained on more than the recovery temperature, below the recrystallization temperature.Therefore every technical parameter of this apparatus and process is complementary, and only limit to the production and processing of multiplex composite rare-earth tungsten electrode, this technology major advantage is: (1) one procedure is through 2 moulds of swaging, 6 procedures in the former B202 technology are reduced to 3 roads, 4 procedures in the B201 technology are reduced to present 2 roads, and working (machining) efficiency doubles.(2) adopt string to beat technology, the base bar passes through last revolving and enters next after the hammer machine forges fast and revolve the hammer machine and forge, and has avoided the loss of heat, thereby economical and energy saving.
