Description
Technical field
The utility model belongs to roller bottom furnace technical field more particularly to a kind of cylinder of roller bottom furnace temperature uniformity control drives
Motivation structure.
Background technique
Currently, Gun Di stove heating area is to drive the switch of cold blast sliding valve to control cold wind air output by pneumatic actuator.System
System is by thermocouple real-time monitoring furnace temperature, and when the temperature is excessively high, system, which provides, opens cold wind valve signal, and solenoid valve is according to electric signal
Actuator action drives valve is controlled to open；Conversely, system, which provides, closes cold wind valve signal when temperature is reduced to preset value,
Solenoid valve controls actuator action drives valve according to electric signal and closes, and the state that opens or closes of valve is opened by two strokes
It closes and detects and feed back to system.Since the temperature uniformity of roller bottom furnace is more demanding, needed in holding stage actuator and valve
Frequently switching on movement just can guarantee temperature uniformity.And actuator is since its architectural characteristic is not particularly suited for frequent movement occasion,
So frequent the result is that the very easy damage such as internal O-ring and guide ring, cylinder body and piston when serious caused by movement
It will appear different degrees of abrasion, caused actuator that cannot be operating normally or stuck, cause it that cannot be opened according to system command
Cold blast sliding valve is opened and closed, not can be effectively controlled cold wind feed amount, causes in-furnace temperature uniformity out of control, temperature uniformity is caused to become
There is overtemperature or temperature not foot phenomenon in difference.And wear after pneumatic actuator can not repair, buy new price of spare parts by compared with
Height, it is frequently impaired to need to frequently replace, production cost is not only increased, and waste time, seriously affects production efficiency.So
It is badly in need of a kind of mechanism and is used for effect instead of pneumatic actuator.

For 100mm.
Further, the adjustment length range at the driving end of connecting rod is 75-100mm, in this way can be according to the installation position of cylinder
It sets and connecting rod is finely adjusted, reduce the installation difficulty between cylinder, connecting rod and valve.
Further, connecting rod swing angle is 24-31 °, can by adjusting the length of connecting rod and the installation site of air cylinder support
Realize the adjustment of the swing angle of connecting rod, it is convenient, flexible, meet different location requirement.
Utility model has the advantages that
1. needing to connect with roller bottom furnace control system when the utility model is used, pass through control system opening come control valve
Off status, instead of the use of pneumatic actuator；
2. roller bottom furnace, by the adjusting of the progress in-furnace temperature of this cylinder driving mechanism, cylinder driving mechanism is reasonable because of it
Structure is also less prone to abrasion even if frequently switching on, and is less prone to failure, and service life greatly improves；
3. roller bottom furnace can receive signal, movement, feedback signal in time, and pass through the effective regulating stove of cylinder driving mechanism
Interior temperature, temperature uniformity is good, be product obtain good comprehensive performance propose precondition, be the stability of properties of product
Provide strong guarantee；
4. continually can significantly act and improve service life, part replacement facilitates fast compared with pneumatic actuator
Speed, it is cheap, temperature uniformity is not only effectively controlled, but also reduce enterprise's production cost, improves production efficiency.
