Description

Technical Field

[0001] The invention relates to the technical field of graphite crucible support, and in particular to a supporting device suitable for a graphite crucible and a supporting method thereof. Background Art

[0002] The main components of graphite crucible are natural flake graphite and binder, so it has the advantages of fast heat conduction, high temperature resistance, good thermal stability, no reaction with the melt, etc. It is a non-ferrous metal melting and casting device. However, it is very easy to oxidize when used in a high-temperature strong oxidizing atmosphere, so when providing different heat sources, a strong oxidizing atmosphere should be avoided, otherwise its service life will be reduced. However, with the development of production technology, some graphite crucibles currently have multiple layers of special glaze on the surface, which can prevent graphite oxidation and enhance the corrosion resistance of the crucible.

[0003] The graphite crucible needs to be supported by a bracket when in use to ensure the stability of the non-ferrous metal when it is melted; the current support device of the graphite crucible has a simple structure and poor applicability; therefore, we designed a support device and a support method suitable for the graphite crucible to solve the above problems.

[0010] Preferably, the locking mechanism comprises a mushroom block fixedly connected to the rectangular block, two trapezoidal metal springs are fixedly connected to the inner wall of the rectangular groove, and the mushroom block is located between the trapezoidal metal springs and abuts against each other.

[0011] Preferably, a support block is fixedly connected to the rectangular block, and the two support blocks are both against the inner wall of the rectangular groove.

[0012] Preferably, the clamping mechanism includes an L-shaped block rotatably mounted on the upper end of the stepped annular block, an adjusting screw threadedly connected to the upper end of the L-shaped block passes through the upper end of the L-shaped block, a handwheel is fixedly connected to the upper end of the adjusting screw, a clamping block is rotatably connected to the bottom of the adjusting screw, a trapezoidal groove is provided at the bottom of the clamping block, a first sleeve is fixedly connected to the inner top of the L-shaped block, a second sleeve is slidably connected to the inside of the first sleeve, and the second sleeve is fixedly connected to the upper end of the clamping block.

[0017] S4, the staff can hold the handle to take out the stepped annular block from the stepped annular groove, and then take out the graphite crucible. Under the limit of the abutting block, the stability of the graphite crucible can be guaranteed. The staff can rotate the handle to rotate the graphite crucible, so that the metal liquid in the graphite crucible can be poured out, which is safe, convenient and labor-saving.

[0019] 1. Place the graphite crucible in the stepped annular block, with the bottom of the graphite crucible against the upper end of the support plate. At this time, the spherical surface against the outer wall of the graphite crucible. The connecting block and the sliding block can be driven to move under the pressure of the graphite crucible. At this time, the spring is compressed, and finally the shape of the connecting block in the stepped annular block is against the outer wall of the graphite crucible. Through the adaptive cooperation of the connecting block and the spring, it can automatically change with the outer wall of the graphite crucible, and the graphite crucible can be stably supported.

[0020] 2. Manually turn the handwheel. The clamping block cannot rotate under the limit of the first sleeve and the second sleeve. Therefore, when the handwheel rotates and the adjusting screw rotates, the clamping block will be driven downward. Finally, the trapezoidal groove at the bottom of the clamping block will abut against the edge of the graphite crucible. The graphite crucible can be stably limited from both sides to ensure its stability.

[0021] 3. Holding the handle, the stepped annular block can be taken out from the stepped annular groove, and then the graphite crucible can be taken out. Under the limit of the abutting block, the stability of the graphite crucible can be guaranteed. The staff can rotate the graphite crucible by turning the handle, so that the metal liquid in the graphite crucible can be poured out. It is safe, convenient and labor-saving to operate.

[0022] In summary, the present invention can automatically follow the outer wall of the graphite crucible through the adaptive connection block and the spring, and can stably support the graphite crucible. Under the support of the support plate, the stability of the graphite crucible can be further guaranteed, and the graphite crucible can be positioned by the tightening block so that the metal liquid in the graphite crucible can be poured out.
