Abstract
A furnace door structure of a trolley type gas heat treatment furnace comprises a furnace door body composed of a furnace door framework and a door board, wherein the furnace door framework is in a square grid shape, two side faces of the furnace door framework are respectively and fixedly connected with the door board, and two compressing arms which are symmetrically arranged are respectively mounted on the upper and lower edges of the furnace door body. The compressing arms are screwed up through bolts, two tensioning arms which are symmetrically arranged are mounted on one side where a handle is arranged on the furnace door body, and the tensioning arms are provided with preloaded springs to prepress. The furnace door structure of the trolley type gas heat treatment furnace presses tightly a furnace door through the compressing arms, and enables a seal effect to be better after the furnace door is closed through the tensioning arms. The furnace door framework can ensure the furnace door to be provided with enough rigidity, so that the furnace door can be ensured to be provided with strong mechanical performance on the whole, especially seal performance and ability to deformation resistance in a high temperature condition are ensured.
Description
Technical field
The utility model relates to a kind of door structure of bogie type gas heat treatment furnace.
Background technology
Heat treatment furnace is the general designation of metal works being carried out the industrial furnace of various metal heat treatmets.Heat treatment furnace can adopt the type of furnace of various process furnace, but requires more strictly to control furnace temperature and furnace atmosphere etc.Heat treatment furnace uses the geseous fuel heating mostly, in order accurately to control furnace temperature, the heat treatment furnace electrically heated that has.Modern thermal treatment (particularly thermo-chemical treatment) technique is increasingly sophisticated, and the form of heat treatment furnace is also a lot.For continuous thermal treatment flow process, must be equipped with suitable continuous heat treating furnace; For cycling thermal treatment process, operating machine and the automatization that adopt the controlled atmosphere of pump circulation and make stove.
Such as the patent No. 200720040085 disclosed a kind of heat treatment furnace structures, purpose provides the less heat treatment furnace of a kind of floor space.It comprises solid solution furnace, the aging oven that is provided with roller bar type e Foerderanlage, quenching tank, and material is transported to the grass-hopper of aging oven from solid solution furnace through quenching tank, solid solution furnace, aging oven are arranged up and down, and liftable grass-hopper is set below the end of solid solution furnace; The bottom surface of the solid solution furnace above grass-hopper has with bottom surface and becomes the split type movable discharge door that is connected; The below of grass-hopper is quenching tank; One side of quenching tank is aging oven; At grass-hopper roller bar type e Foerderanlage is set, the roller rod on grass-hopper, solid solution furnace, the aging oven parallels.
Traditional door structure and common door and window are as good as, so in order to guarantee the structural strength of fire door, particularly the intensity under hot environment just need to make an effort in the size of fire door, but the larger manufacturing cost of size is higher, use also just all the more inconvenient.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of door structure of simple in structure, bogie type gas heat treatment furnace that mechanical property is strong is provided.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of door structure of bogie type gas heat treatment furnace, comprise the oven door body that is consisted of by fire door skeleton and door-plate, described fire door skeleton is pattern, two sides of fire door skeleton are fixedly connected with door-plate respectively, be separately installed with two clamping arms that are arranged symmetrically with on the up and down both sides of oven door body, described clamping arm is by bolt tightening, and a side that is provided with handle in oven door body is equipped with two tension arms that are arranged symmetrically with, and described tension arm is provided with preloading spring and carries out precompressed.
The door structure of bogie type gas heat treatment furnace described in the utility model, by clamping arm fire door is compressed, better by the sealing effectiveness of straining after arm is closed fire door, and the fire door skeleton can guarantee that fire door has enough rigidity, so can guarantee that on the whole fire door has stronger mechanical property, particularly the ability of the stopping property under hot conditions and resistance to deformation.
Described clamping arm and tension arm adopt respectively paired setting, and the position is symmetrical, can guarantee like this stress equalization of oven door body structure, guarantee sealing effectiveness and rigidity.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure iron of the door structure of bogie type gas heat treatment furnace described in the utility model.
Fig. 2 is the vertical view of the door structure of bogie type gas heat treatment furnace described in the utility model;
Fig. 3 is the side-view of the door structure of bogie type gas heat treatment furnace described in the utility model.
Embodiment
As Figure 1-3, the door structure of the described bogie type gas heat treatment furnace of the utility model embodiment, comprise the oven door body that is consisted of by fire door skeleton 1 and door-plate 2, described fire door skeleton 1 is pattern, two sides of fire door skeleton 1 are fixedly connected with door-plate 2 respectively, be separately installed with two clamping arms that are arranged symmetrically with 3 on the up and down both sides of oven door body, described compression 3 is tightened by bolt 5, a side that is provided with handle in oven door body is equipped with two tension arms 4 that are arranged symmetrically with, and described tension arm 4 is provided with preloading spring 6 and carries out precompressed.
The door structure of bogie type gas heat treatment furnace described in the utility model, by clamping arm fire door is compressed, better by the sealing effectiveness of straining after arm is closed fire door, and the fire door skeleton can guarantee that fire door has enough rigidity, so can guarantee that on the whole fire door has stronger mechanical property, particularly the ability of the stopping property under hot conditions and resistance to deformation.
