AI Technical Summary
When the existing vacuum furnace door is opened, the weight is entirely supported by the hinge, which causes excessive stress on the hinge pin, making it prone to deformation and resulting in a short service life.
A vacuum furnace door hinge device was designed. The downward pressure of the furnace door weight is transferred to the furnace body through the support component, which reduces the pressure on the first pin. The soft pad is used to avoid rigid contact and improve the service life of the hinge.
It effectively prevents hinge pin deformation, extends service life, ensures normal use of the furnace door, and improves practicality by using soft pads to prevent damage.
