Technical Field
[0001] The utility model belongs to the technical field of hot isostatic pressing production, in particular to a grabbing device for a hot isostatic pressing heat insulation screen. Background Art
[0002] The hot isostatic pressing process is to place the product in a closed container, apply equal pressure in all directions to the product and heat it. Under the action of high temperature and high pressure, the product can be sintered and densified. With the rapid development of additive manufacturing technology and the increasing maturity of casting technology, the shapes of processed objects tend to be more complicated. At the same time, the speed of hot isostatic pressing machines towards large-scale development is also getting faster and faster. During the production and operation of hot isostatic pressing machines, the heat shield needs to be taken out with a tool before loading and unloading. With the large-scale hot isostatic pressing equipment, the diameter and height of the hot isostatic pressing equipment are increased accordingly. The increase in the diameter of the equipment increases the difficulty of operation for the operator. The existing heat shield extraction tooling is mostly a connecting rod structure that allows the locking rod to rotate simultaneously, which is equivalent to the operator rotating multiple locking rods at the same time. This extraction tooling has high requirements on the strength of the operator. Therefore, a single-operated, labor-saving heat shield grabbing device is needed. Utility Model Content
