Make.
In order to which technical scheme of the present invention is more clearly understood, with reference to the fatigue test of certain folding door, to this hair
Bright essential characteristics and advantage are further described, but the invention is not limited in listed embodiments.Specific experiment process
It is as follows:
The first step:Folding door is installed on main frame 1, as shown in Figure 1, folding door installs afterwards, it can be achieved that folding door
Opening and closing;
Second step:First cylinder and the second cylinder are installed, and combine the installation of four connectors, it can be achieved that cylinder
360 ° of rotations;
Third walks:Cylinder and external air source are connected, cylinder system is constituted, then connects solenoid valve and relay, is led to
It crosses and controls relay with test control module, to realize the reciprocal fortune of the first cylinder of control and second cylinder the two cylinders
It is dynamic.
Wherein, during fatigue test, the loop control process of a complete folding door is as follows:First, experiment control
Molding block is by controlling the first relay switch so that the piston rod of the first cylinder 2 is stretched out, and the first folding door 8 is made to be opened to 90 °
Then angle controls the second relay switch so that the piston rod of the second cylinder 3 is stretched out, and the second folding door 9 is made also to be opened to 90 °
Thus the opening state of entire folding door is completed at angle;Then, by controlling the second relay switch so that the work of the second cylinder 3
Stopper rod is shunk, and so that the second folding door 9 is closed angle, and make the second folding door 9 and the first folding door 8 at horizontality, then,
The first relay switch is controlled again so that the piston rod of the first cylinder 2 is shunk, so that the first folding door 8 is closed into 0 ° of angle,
Thus the closed state for completing folding door is finally completed loop control operation, realize folding door of control unlatching and
Closed circulation.
It therefore,, can when user needs to test some folding door and whether can switch and be closed 10,000 times on concrete practice
By test control module, default 10,000 loop controls operation is repeated, if after being finished, there are no appearance
Phenomena such as connector of door connecting portion damages, configuration part falls off and fails on door (can need also to define according to user
These phenomenons), judge that folding door can reach 10,000 service life, otherwise (i.e. midway is broken down), judgement, which is not inconsistent, to be shared
Service life demand of the family to folding door.
Therefore, for fatigue test system provided by the present invention, the demand of folding door fatigue test is fully met, is tied
Structure is simple, and cost is relatively low.The invention can be applied to similar folding door and open and close fatigue test, have preferable versatility and practicality
Property.
