The utility model discloses large -scale powder blank has been solved effectively in the produced influence of sintering process metal accessory power.
Description
Technical field
This utility model is related to a kind of rare metal powder smelting device, relates in particular to rare metal industry production big
A kind of novel powder being used during type powder smelting blank smelts vacuum sintering furnace.
Background technology
General vacuum-sintering equipment in rare metal powder under vacuum sintering process, by compressing metal dust
Can occur during blank first to expand after-contraction phenomenon, although the metal creep power producing therefrom is less, to whole sintering process
Can have adverse effect on, even result in sintering and cannot be carried out.Existing powder metallurgy billet about in the range of 5～12kg, and with
The development in market, the market demand is bigger powder metallurgy billet, need to sinter large-scale blank it is therefore necessary to traditional
Vacuum sintering furnace is transformed.
Its operation principle of the vacuum sintering furnace being used now can see accompanying drawing 1: using upper and lower two electrodes, by powder batch
It is held between upper/lower electrode, after energising, utilize blank self-heating to heat up；Top electrode is fixing, and bottom electrode adopts two to determine
Pulley determines the direction of power so as to can move up and down, and equilbrium position during work is to be completed by increasing and decreasing counterweight；Upper/lower electrode
It is integrally placed in a vacuum chamber, in sintering process when powder batch expands, bottom electrode can move down, and works as powder
When blank shrinks, bottom electrode can move up, and overcomes the impact caused by metal creep power with this.Because electrical power increases
Greatly, the electrode of its equipment also increases therewith, and weight increases, because fixed pulley is not laborsaving, for asking power energy counterweight similarly to increase
Plus, now the inertia force of bottom electrode movable device increases also with the increase of electrode, and metal creep power is not enough to overcome
So big inertia force enables bottom electrode to move up and down, so now not reaching the impact effect eliminating metal creep power.
Utility model content
The deficiency existing for above-mentioned technology, for eliminating the metal creep power producing during vacuum-sintering, this utility model carries
For a kind of novel powder smelt vacuum sintering furnace, this utility model by using increase by two groups of running blocks solve Top electrode live
The problem that motivation structure inertia increases, thus can make the inertia force of bottom electrode movable device will not increase because of the deadweight of bottom electrode
And be multiplied.
For achieving the above object, this utility model provides a kind of novel powder to smelt vacuum sintering furnace, by Top electrode (1),
Upper grip (2), powder batch (3), body of heater (4), lower chuck (5), bottom electrode (6), fixed pulley one (7), fixed pulley two (8), lead
Messenger (9), movable pulley (10), counterweight (11) composition, it is characterized by: it is fixing that upper grip (2) is passed through in powder batch (3) one end
It is connected in Top electrode (1), powder batch (3) other end is connected on bottom electrode (6) by lower chuck (5), Top electrode (1)
For fix, bottom electrode (6) is equipped with two groups of fixed pulleys one (7) and fixed pulley two (8), fixed pulley one (7) and fixed pulley two (8)
Movable pulley (10) is connected by pull rope (9), pull rope (9) end is connected with counterweight (11).
Advantage of the present utility model is: to be solved using two groups of running blocks, what Top electrode movable device inertia increased asks
Topic.Because dynamic sliding group can be laborsaving, when electrode weight increases instantly, the weight of its counterweight does not need to be multiplied.Thus make
The inertia force of energy bottom electrode movable device, will not be multiplied because the deadweight of bottom electrode increases, this utility model is effectively
Solving large-scale powder batch is affecting produced by sintering process metal creep power.
This utility model successfully solves large-scale powder batch to be affected produced by sintering process metal creep power.
Brief description
Fig. 1 is schematic diagram before improvement；
Fig. 2 is structural representation of the present utility model；
Marginal data:
Top electrode (1), upper grip (2), powder batch (3), body of heater (4), lower chuck (5), bottom electrode (6), fixed pulley one
(7), fixed pulley two (8), pull rope (9), movable pulley (10), counterweight (11).
Specific embodiment
With reference to Fig. 2, the utility model is described in further detail:
This utility model provides a kind of novel powder to smelt vacuum sintering furnace, by Top electrode (1), upper grip (2), powder base
Material (3), body of heater (4), lower chuck (5), bottom electrode (6), fixed pulley one (7), fixed pulley two (8), pull rope (9), movable pulley
(10), counterweight (11) composition, it is characterized by: powder batch (3) one end is fixedly connected on Top electrode by upper grip (2)
(1) on, powder batch (3) other end is connected on bottom electrode (6) by lower chuck (5), and Top electrode (1) is fixing, under
Equipped with two groups of fixed pulleys one (7) and fixed pulley two (8), fixed pulley one (7) and fixed pulley two (8) pass through pull rope (9) to electrode (6)
Connect movable pulley (10), pull rope (9) end is connected with counterweight (11).
In sintering process, powder batch (3) is placed in body of heater (4), upper/lower electrode is integrally placed in a vacuum chamber,
Equilbrium position during work is to be completed by increasing and decreasing counterweight, and two groups of running blocks are solving the increase of Top electrode movable device inertia
Problem.Because dynamic sliding group can be laborsaving, when electrode weight increases instantly, the weight of its counterweight does not need to be multiplied.Thus
Enable the inertia force of bottom electrode movable device, will not be multiplied in practice it has proved that this side because the deadweight of bottom electrode increases
Method successfully solves large-scale powder batch to be affected produced by sintering process metal creep power.
