The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figs 1-4, a kind of PTFE Large blank sintering rack, including frame body 2, support tube 5 and branch
Support, support tube 5 are fixed on 2 inside of frame body, and support tube 5 is to be in U-shape, and there are gap, supports between support tube 5 and frame body bottom
Frame is installed in the gap of frame body 2 and support tube 5, and support frame includes arc plate 6 and pedestal 7, and arc plate 6 is fixed on pedestal 7, arc plate
6 and the radian of 5 lower part of support tube match but do not contact, the inner wall fitting of support tube 5 is placed with aluminium sheet 8, and aluminium sheet 8 is also in U-shape
Structure is evenly equipped with several ventilation holes on aluminium sheet 8, support tube 5 and arc plate 6.
Several hanging rings 1 are connected on the frame body 2.
The two sides of the support tube 5 are fixed on frame body 2 by mounting plate 9, and mounting plate 9 is L shaped plate, and mounting plate 9 is fixed
Upper surface and lateral surface in frame body 2.
2 upper end of frame body is equipped with slot 10 at the position of hanging ring 1, and when hanging ring 1 is laid flat, hanging ring 1 is inserted into slot 10
It is interior, at this point, the upper surface of hanging ring 1 is under the upper surface of frame body 2.
The frame body 2 is rectangular frame.
Support rod 4 is equipped between the outer wall and frame body 2 of the support tube 5, one end of support rod 4 is fixed on 2 inside of frame body,
The other end of support rod 4 is fixed with supporting bracket 3, and supporting bracket 3 is rubber material, and supporting bracket 3 holds the outer wall of support tube 5.
Each support frame is set there are two pedestal 7, is the gap for ventilation between two pedestals 7.
In use, blank is placed into support tube 5, device connection blank is sent into sintering furnace using crane, branch
Support plays the role of Auxiliary support to the bottom of support tube 5, prevents from causing support tube 5 together with blank one since blank is overweight
It rises and falls.Support rod 4 and supporting bracket 3 also function to lateral support effect to support tube 5.It needs to place 4 simultaneously in one sintering furnace
The rack of a present apparatus, for the state stacked two-by-two, when whole device enters in sintering furnace, hanging ring 1 is due to gravity
