Description
Technical field
The present invention relates to a kind of swing door structure, the swing door structure of especially a kind of heating furnace.
Background technique
With releasing one after another for the mandatory rules of law such as national automobile central collision, side impact, discharge, body of a motor car steel with material just increasingly
It is faced with formidable challenges, automobile is become using advanced high-strength steel, such as DP steel, TRIP steel, high reaming steel also undisputedly
The main trend of material.It by the thinned and high-strength Proper Match of bodywork parts, not only can effectively mitigate car body weight, reduce oil
Consumption, and may insure, improve safety and the comfort of vehicle；But for process for stamping and forming, be thinned and it is high-strength be dislike
The double factor for changing formability not only makes bodywork parts be easy cracking in forming process, but also is easy to produce excessive rebound,
Influence the subsequent assembly of vehicle body；In addition, the high-strength service performance to bodywork parts itself is thinned, especially stiffness characteristics are generated not
Benefit influences.It is more than the high-strength steel of 1000M Pa for intensity, conventional ones technique is often helpless, a kind of novel forming work
The drop stamping technology of skill, special high-strength steel sheet is come into being.Drop stamping technology is to utilize the principle of metallized thermoplastic forming, energy
It is enough to realize while forming to the quenching heat treatment of plate, the forming property of material is improved, high-intensitive superelevation is greatly expanded
For strength steel in the application range of auto parts, this technology is that the plate of wanted punching press is put into heating furnace to be preheated to 900 ° or more
When, it is taken out in dysphoria with smothery sensation stamping die in heating furnace, then carry out punching press.
Through retrieving, as Chinese patent literature discloses a kind of thermoforming stove [application number: 01820373674.X；It is open
Number: CN 208042779U].This thermoforming stove, it is characterised in that: including hot stove ontology, the first limited block, adjustment bolt,

It is connected in the middle part of bar with gantry rotation, the actuator that the actively fork other end can be such that it swings up and down with one is connected, driven lever one
End and fire door rotation connection, the driven lever other end are connected with gantry rotation.
Using the above structure, pass through the structures such as actively fork, driven lever and actuator, so that it may realize fire door unlatching or
Person closes operation, is not in the stuck phenomenon of fire door, can be to avoid unnecessary shutdown, and stability in use is good.
The actively fork is straight-bar.
As another situation, the actively fork is curved bar.
The actuator is cylinder, and the cylinder body of cylinder is connect with gantry rotation, the piston rod end of cylinder and actively fork
Other end rotation connection.
As second situation, the actuator is hydraulic cylinder, and the cylinder body of hydraulic cylinder is connect with gantry rotation, and hydraulic cylinder
Piston rod end and the actively fork other end be rotatablely connected.
As the third situation, the actuator is push-rod electric machine, and the fuselage of push-rod electric machine is connect with gantry rotation, and is pushed away
The push rod end of bar motor and the actively fork other end are rotatablely connected.
Reinforcement screen frame is further fixed on the fire door.
Using the above structure, it is deformed by reinforcing the avoidable fire door of screen frame.
Also have between the actuator and actively fork and adjusts component.
The adjusting component includes adjusting rod, movable block and locking bolt, and adjusting rod one end and actuator are fixedly connected with, and is adjusted
The bar other end has sliding slot, and movable block is slidably arranged in sliding slot, and movable block and the actively fork other end are rotatablely connected, and locks spiral shell
Bolt is threaded on movable block, and locking bolt end can lean with movable block.
It using the above structure,, can be square by adjusting rod, movable block and locking bolt in the case where being changed without impeller
Just the unlatching size of fire door is regulated and controled, so that the heat treatment of different workpieces is better met, it is practical.
Also there is graduation mark on the adjusting rod.
Compared with prior art, the swing door structure of this heating furnace has the advantages that this:
Pass through the structures such as actively fork, driven lever and actuator in the present invention, so that it may realize unlatching or the pass of fire door
Operation is closed, is not in the stuck phenomenon of fire door, can be to avoid unnecessary shutdown, stability in use is good.
