Material splashes from both sides, reduces loss of material.Even more preferably, anti-43 plate of guard block is transparent, and can directly observe lithium metal particle
It whether is flow to the case where blocking in basin and with the presence or absence of mold 13 that turns in extruded product after contacting anti-43 plate of guard block, while
Convenient and healthy cleaning, it is simple and convenient.Technical solution still more preferably are as follows: the anti-43 plate transversal cross-section shape of guard block is recessed
Type groove shape, anti-43 plate of the guard block left and right sides are integrally formed the flange for being provided with and extending towards the cutter assembly 23 bending.
In this way, anti-43 plate transversal cross-section shape of guard block is concave channel-shaped and both ends are arranged towards the curved flange of rotary cutter device, it is recessed
43 plate of anti-guard block of type groove shape can prevent material from splashing from both sides, reduce loss of material, to improve the product of lithium metal particle
The rate of recovery；Flange further decreases loss of material and splashing.
A kind of process units of metallic lithium sand of the invention, correlation that please refer to figs. 1 to 4 is each to be schemed, in front technical solution
On the basis of it may also is that 14 height of lithium slot of leading lower than the 13 front height 1-3mm of mold.In this way, it is high to lead lithium slot 14
Degree 1-3mm low compared with the height of mold 13, so that the 131 strip metal lithium silk of portalling in mold 13 is easily accessible and leads in lithium slot 14,
It is not easy to block.
The method of the process units of a kind of metallic lithium sand of the invention, comprising the following steps: mold 13 is fixed on mould by a.
Have on pedestal 15；B. start lithium sand shear 2；C. lithium metal ingot is put into squeeze cylinder 12；D. start lithium sand pressurizing unit 1
On extruding program, driving pressure ram 11, which advances, squeezes the lithium metal ingot that has been placed in squeeze cylinder 12, and lithium metal ingot is squeezed into
The strip lithium silk of the limited specification of mold 13；E. strip lithium silk is led lithium slot 14 and carries out automatic shearing by lithium sand shear 2, is led to
Overregulate the metallic lithium sand of dimensions needed for squeeze pressure obtains；F. it after the lithium metal in each squeeze cylinder 12 has squeezed, squeezes
Pressure driven by program pressure ram 11 exits squeeze cylinder 12, and retreats at from 12 30-40cm of squeeze cylinder；G. above-mentioned c-f step is repeated
Suddenly, consecutive production obtains metallic lithium sand.In this way, the metallic lithium sand size produced through the above steps is controllable uniformly, product matter
