Description

Graphite fixture for outer square inner circle

Technical Field

The present application relates to the technical field of graphite processing, and in particular to a clamping fixture for outer square inner circle graphite.

Background Art

Graphite is one of the allotropes of carbon, with the chemical formula C. There are two types of graphite: hexagonal and trigonal. When heated above a certain temperature, the latter transforms into the former, making the system more stable. Due to its high melting point, corrosion resistance, and acid insolubility, graphite is used to make high-temperature crucibles for smelting; it is slippery and used as a lubricant in the machinery industry; it has good electrical conductivity and is used to make electrodes, etc. The so-called high-carbon graphite with a relatively pure composition can be used as a neutron moderator in atomic reactors.

Upon checking, the disclosure (announcement) number: CN218169166U discloses a graphite clamping jig for welding. This technology discloses "including an electrode plate, a limiter and a pressure block. The electrode plate is used to be fixed on the welding equipment and used to support the lower surface of the graphite block. The limiter is fixed on the electrode plate. The limiter has a graphite clamping limiter surface facing the rear side. The graphite clamping limiter surface is used to cooperate with the front side stop of the graphite block. The pressure block is detachably fixed on the electrode plate. Two pressure blocks are relatively arranged. The two pressure blocks are used to clamp the left and right sides of the graphite block to limit the displacement of the graphite block in the up and down directions and the left and right directions.
