Technical Field
[0001] This utility model relates to the field of lithium ingot cutting technology, specifically to a lithium ingot cutting device. Background Technology
[0002] In the production of lithium ingots, the head of the cast lithium ingot is prone to porosity due to the uneven flow of molten lithium within the mold during the initial pouring stage, and the tail of the ingot often develops deep shrinkage cavities after cooling. Therefore, the head and tail portions do not meet the quality requirements of the finished lithium ingot and need to be trimmed according to the desired product length. Due to the unstable chemical properties of lithium, these operations must be performed within a sealed chamber.
[0003] Application No. 201911115712.7 discloses an adjustable-gap lithium ingot cutting device, which mainly uses steel wire to cut lithium ingots. Using steel wire for cutting is prone to the following problems: 1. The direction of the tension on the steel wire is unstable during cutting, resulting in uneven cuts and poor cutting effect; 2. The service life of the cutting steel wire is short, increasing production costs; 3. Frequent replacement of steel wire reduces production efficiency, and workers need to operate in a sealed chamber, resulting in high labor intensity. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] like Figures 1 to 4 As shown, a lithium ingot cutting device includes a cutting cylinder 1, a lifting bracket 2, a fixed blade holder 3, a material support platform 4, a cutting blade 5, and a pressing cylinder 6.
[0025] The upper surface of the material support platform 4 is provided with an arc-shaped groove for placing lithium ingots, and the lithium ingots are placed in the groove on the material support platform 4. The pressure cylinder 6 is located above the material support platform 4, and the lower surface of the pressure cylinder 6 is provided with an arc-shaped groove. The material support platform 4 and the pressure cylinder 6 together fix the lithium ingots. The cutting cylinder 1 is located above the pressure cylinder 6, and the lower end of the piston rod of the cutting cylinder 1 is provided with a lifting bracket 2. The cutting blade 5 is mounted on the lifting bracket 2 through a fixed blade holder 3.
[0026] The pressure cylinder 6 is provided with a vertically penetrating first guide groove 7 for the cutting blade 5 to pass through. The cutting blade 5 passes through the first guide groove 7 on the pressure cylinder 6 to cut the lithium ingot. Under the action of the first guide groove 7, the cutting blade 5 cuts the lithium ingot along the direction of the first guide groove 7, ensuring the flatness and perpendicularity of the cut and improving the product quality of the lithium ingot. The cutting cylinder 1 drives the cutting blade 5 to move downward to cut the lithium ingot.
[0027] As a preferred embodiment of this invention, the cutting blade 5 is provided in two sets: a first cutting blade and a second cutting blade. The first cutting blade is located to the left of the second cutting blade. The first cutting blade is used to cut one end of the lithium ingot, and the second cutting blade is used to cut the other end of the lithium ingot. By setting up two sets of cutting blades 5, the beginning and end of the lithium ingot can be cut simultaneously, which greatly improves the cutting efficiency compared to traditional wire cutting, which can only cut one end of the lithium ingot at a time. Correspondingly, the left and right parts of the pressure cylinder 6 are provided with first guide grooves 7 for the insertion of the cutting blades 5, which provide guidance for the cutting of the first cutting blade and the second cutting blade, respectively.
[0028] As a preferred embodiment of this invention, the outer surface of the pressure cylinder 6 is provided with an annular protrusion, and the first guide groove 7 is a vertically formed slot on the annular protrusion that communicates with the arc-shaped groove of the pressure cylinder 6. The length of the first guide groove 7 in the longitudinal direction is greater than the diameter of the lithium ingot and the length of the cutting blade 5, and the width of the first guide groove 7 in the transverse direction is greater than the thickness of the cutting blade 5 by 2-3 mm. This allows the cutting blade 5 to be inserted into the pressure cylinder 6 through the first guide groove 7 on the annular protrusion to cut the lithium ingot located below the pressure cylinder 6. The larger the outer diameter of the annular protrusion, the longer the length of the first guide groove 7 in the vertical direction, resulting in a better guiding effect. This prevents the cutting blade 5 from bending and deforming under force when in contact with the lithium ingot, and further ensures the flatness of the cut surface of the lithium ingot, preventing tilting.
[0029] The pressing cylinder 6 is parallel to the axial direction of the lithium ingot in the horizontal direction, corresponding to the X-axis in the coordinate system, the Y-axis in the vertical direction, and the Z-axis in the vertical direction.
[0030] As a preferred technical solution of this utility model, the lifting bracket 2 is provided with a limiting through hole 8, the fixed knife seat 3 is provided with a positioning through hole, and the positioning pin passes through the positioning through hole on the fixed knife seat 3 and the limiting through hole 8 on the lifting rod bracket to fix the fixed knife seat 3 to the lifting bracket 2.
[0031] The connection between the fixed tool holder 3 and the lifting bracket 2 is not limited to locating pins; bolts and nuts can also be used to connect and fix the two. This allows for a detachable connection between the fixed tool holder 3 and the lifting bracket 2, facilitating tool replacement.
[0032] As a preferred embodiment of this invention, the lifting bracket 2 has several sets of limiting through holes 8, which are evenly arranged along the transverse direction of the lifting bracket 2. By setting these limiting through holes 8, the specific connection position between the fixed blade holder 3 and the lifting bracket 2 can be adjusted, allowing for adjustable spacing between the two sets of cutting blades 5 to accommodate lithium ingot cutting of different lengths, and simultaneously enabling adjustable lithium ingot cutting length. Correspondingly, the pressure cylinder 6 also has several sets of first guide grooves 7, corresponding to the limiting through holes 8 on the lifting bracket 2, so that the first guide grooves 7 on the pressure cylinder 6 can match the adjustment of the cutting blades 5 on the lifting bracket 2.
[0033] As a preferred embodiment of this invention, the system further includes a lifting cylinder 10 and a lifting guide frame 11. The lifting cylinder 10 is located on one side of the material support platform 4. The lifting guide frame 11 is located above the lifting cylinder 10 and has a guide hole through which the piston rod of the lifting cylinder 10 passes. The piston rod of the cylinder passes through the guide hole on the lifting guide frame 11 and connects to the pressure cylinder 6. The lifting cylinder 10 drives the pressure cylinder 6 to move up and down. When the lithium ingot is placed on the material support platform 4, the piston rod of the lifting cylinder 10 retracts, driving the pressure cylinder 6 to cooperate with the material support platform 4 to clamp the lithium ingot. The lifting function of the pressure cylinder 6 provides ample operating space for the loading and unloading of lithium ingots, effectively avoiding rubbing within the cylindrical mold and improving the surface quality of the lithium ingot.
[0034] The first guide groove 7 on the pressure cylinder 6 alone only allows the cutting blade 5 to cut lithium ingots longer than the support platform 4, thus limiting the use of the support platform 4. To solve this problem, as a preferred embodiment of this invention, the support platform 4 is provided with a vertically arranged second guide groove 9. Several sets of the second guide groove 9 are evenly distributed along the transverse length of the support platform 4. A corresponding set of first guide grooves 7 is provided on the pressure cylinder 6 above each second guide groove 9 on the support platform 4. This allows the cutting blade 5 to pass through the first guide groove 7 and the second guide groove 9 to cut the lithium ingot. The first guide groove 7 and the second guide groove 9 work together to further guide the cutting direction of the cutting blade 5.
[0035] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be included within the protection scope of the present invention.
