Problems solved by technology

It sinters the ceramic roller of the furnace door and the ceramic furnace door plate to form a whole, which meets the requirements of high temperature resistance and still has a certain strength at high temperature, but because the ceramic is relatively brittle and cannot withstand thermal stress, the ceramic roller and Ceramic plates often chip
As long as one part breaks, the entire furnace door will be scrapped and cannot be repaired, which affects the normal use of the equipment, increases maintenance costs and repair time, and affects normal production

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 , figure 2 and image 3 As shown, a furnace door of a thermoforming furnace is rotatably connected to the bearing seats on both sides of the thermoforming furnace body. The furnace door includes a door body 100 for closing the furnace body inlet or outlet, and a door body 100 A fixedly connected rotating body, the rotating body includes a rotating shaft 201 fixedly connected to the door body 100, a detachably connected shaft head 202 at both ends of the rotating shaft 201, and the shaft heads 202 at both ends are respectively installed in rotation with the bearing seats on both sides, The shaft head 202 is made of heat-resistant steel, and a heat insulation mechanism is provided between the rotating shaft 201 and the shaft head 202 .

[0026] Specifically, the shaft head 202 is formed with ...

Abstract

The invention relates to a furnace door of a thermal forming furnace. The furnace door is rotationally connected to bearing blocks on the two sides of a furnace body of the thermal forming furnace, and the furnace door comprises a door body and a rotating body, wherein the door body is used for sealing an inlet or an outlet of the furnace body, and the rotating body is fixedly connected with the door body; the rotating body comprises a rotating shaft and shaft heads, the rotating shaft is fixedly connected with the door body, the shaft heads are connected to the two ends of the rotating shaft,and the shaft heads at the two ends are rotationally matched with bearing blocks on the two sides to be installed respectively, the shaft heads are made of heat-resistant steel materials, and a heatinsulation mechanism is arranged between the rotating shaft and the shaft heads. According to the furnace door, the heat radiation of the furnace door is reduced, and the heating efficiency of a furnace is improved; the influence of high temperature on the service life of the bearing blocks is avoided through the heat insulation mechanism, and damage is avoided; and the time of production halt caused by damage of the furnace door is avoided, and the utilization rate of the furnace is improved.

Description

technical field [0001] The invention relates to the field of industrial heat treatment, in particular to a furnace door of a thermoforming furnace. Background technique [0002] Steel sheet hot stamping is a new technology developed in the automotive industry in the past ten years, and one of its core equipment is a roller hearth thermoforming furnace (PH furnace). Roller hearth furnaces are equipped with two doors, one at the inlet and one at the outlet. It has a very important function to reduce the atmosphere and heat loss in the furnace when feeding and discharging materials. The furnace door of the common thermoforming furnace adopts heat-resistant steel structure, and the furnace door opens up and down, which has poor thermal insulation performance and is easy to deform. [0003] There is also a structure using a revolving furnace door. What it adopts is ceramic material, when the tablet comes out of the furnace, the furnace door swings open, otherwise it closes. I...
