【product description】
This equipment is suitable for testing various mechanical properties and fatigue resistance (repeated opening and closing) performance of doors and windows. Widely used in various materials for construction with side doors, windows, sliding doors, windows, top-hung, middle-hung, bottom-hung and casement bottom-hung and sliding-hung windows. Applicable inspection items include: locking device (handle) switching force, window opening and closing force, hanging weight, warping or bending deformation, twisting, diagonal deformation, support, opening limiter, strong closing, Repeated opening and closing performance (with handle switch action) is an ideal testing equipment for quality inspection departments, construction inspection, door and window processing, and five-piece production enterprises.

【Execution standard】
GB/T 29739-2013 "Test method for durability of doors and windows with repeated opening and closing"
GB/T 9158-2015 "Testing methods for mechanical properties of building doors and windows"

The equipment is divided into two types: manipulator and servo motor.
The manipulator is an upgraded version. Its advantages: 1. Reduce the consumption of experimental consumables; 2. The manipulator adopts bionic design, which can carry out special experiments and meet the needs of research topics.

【Equipment composition】
This equipment consists of four parts: control unit, door and window mounting frame, deformation measurement unit, and repeated opening and closing execution unit.

1. Control unit:
The function of the control unit is to apply the required test load to the doors and windows, send control signals to the repeated opening and closing device to control its action, and receive, organize and store the deformation signals measured by the deformation measuring device. The control unit adopts advanced microcomputer control technology, modular design, stable and reliable system, strong anti-interference ability.

2. Door and window mounting bracket:
The function of the door and window mounting frame is to install and fix the doors and windows. It is welded by section steel, with high strength and stability.

3. Deformation measurement unit, repeated opening and closing unit:
The function is to complete repeated opening and closing actions under the control of the host. Imported cylinders and pneumatic components are used, with long service life, stable and durable, and the uniquely designed device can complete complex handle twisting actions. The two-stage air source filter effectively eliminates the moisture brought by the air pump during operation and prolongs the service life of the pneumatic components.

【Technical Features】
1. Powerful function: In addition to completing the conventional mechanical performance test of doors and windows, the uniquely designed device can complete the complex handle twisting action, which fully meets the requirements of the national standard and is currently the leading technology in China.
2. The rigidity of the whole machine is large: the frame of the whole machine is welded by section steel, which has high strength and strong stability.
3. Strong durability: It adopts imported cylinder and pneumatic components, and has two-stage air source filter device, which ensures the fatigue life of more than 500,000 times.
4. Precise control and powerful functions: It adopts advanced microcomputer control technology, modular design, integrates a variety of door and window opening action methods, and has a wide range of applications. It has the functions of power-off memory and data automatic saving. The test can be continued after the test.
