The computer controls the rotation of the AC servo motor through the speed regulation system, and after deceleration by the deceleration system, drives the moving crossbeam to rise and fall through the ball screw pair, completing mechanical performance tests and analysis research on metal and non-metal specimens such as tension, compression, bending, shear, tearing, and peeling. It can automatically calculate test parameters such as ReH, ReL, Rp0.2, Fm, Rt0.5, Rt0.6, Rt0.65, Rt0.7, Rm, E, etc., and can conduct tests and provide data according to GB, ISO, DIN, ASTM, JIS, etc. This model can adopt a dual space or single space design. No pollution, low noise, with a very wide speed range and beam movement distance. Mainly used for detecting materials such as steel, cast iron, stainless steel, aluminum alloy, copper, titanium alloy, etc., it is an ideal testing equipment for factories, mines, research institutes, universities, quality supervision and other industries.

2. The testing machine adopts an AC servo speed control system with high speed regulation accuracy and stable performanceUsing communication servo motors as drive systems; The control and data processing software based on database technology using Windows XP as the operating platform adopts virtual instrument technology instead of traditional digital tubes and oscilloscopes, realizing the screen display of test force, peak test force, beam displacement, sample deformation, and test curve. All test operations can be completed on the computer screen by mouse input, with a good human-machine interface and convenient operation; The dual channel fully digital programmable amplifier inserted into the PC realizes true physical zeroing, gain adjustment, and automatic zeroing and calibration of test force measurement, without any analog adjustment links.

Structural performance:

1High strength host:The product adopts a dual space door structure, with the upper space stretched and the lower space compressed and bent. The host part consists of four guide columns, an upper crossbeam, a middle crossbeam, and a workbench, forming a floor standing frame. The speed control system is installed at the lower part of the workbench. The AC servo motor with high speed regulation accuracy, wide range, and stable performance drives the ball screw pair to rotate through the synchronous toothed belt reduction system. The ball screw pair drives the middle crossbeam and drives the stretching auxiliary tool (or compression, bending and other auxiliary tools) to move up and down, realizing the loading and unloading of the sample. This structure ensures that the rack has sufficient rigidity while achieving efficient and smooth transmission.

Portal frame structure, integral stamped shell, clean and elegant appearance.

Ball screws only withstand tensile forces, effectively extending their lifespan and rigidity stability

The loading method of the screw pair, double nut back tightening to eliminate clearance, ensures high rigidity and high dynamic performance of the system

2Structural principle:Adopting circular arc synchronous pulley deceleration and zero clearance ball screw pair transmission, the transmission is seamless, ensuring the control of test force and deformation speed. The motor drives the screw to rotate after being decelerated by a three-stage synchronous pulley, thereby driving the moving crossbeam to perform linear motion at a selected speed to achieve various experimental functions

3Host framework:The surface is treated with passivation, primer, topcoat and other processes.

4. Ball screw pair: Ball screw pair is used to ensure seamless transmission and control accuracy. The double set ball screw is installed on both sides of the frame, with the upper end connected to the upper crossbeam bearing, the ball nut fixedly connected to the middle movable crossbeam, and the lower end connected to the lower end of the frame table with wheels. The rotation of the wheels drives the ball screw to rotate, causing tension or pressure to rise and fall on the middle crossbeam. The use of the central crossbeam for rapid lifting can also adjust the testing space.

4Transmission system:Installed at the bottom of the workbench, it consists of a synchronous toothed belt and synchronous toothed belt pulley. This transmission system can effectively eliminate clearances and slip phenomena during the transmission process, ensuring control performance. The system adopts a two-stage deceleration, consisting of two synchronous toothed belts and five synchronous belt pulleys. This machine does not use a reducer and adopts a direct reduction method with a transmission system. The advantages of this reduction method are twofold: low noise and maintenance free.

5Host crossbeam:Divided into upper crossbeam and middle crossbeam, made of medium thickness carbon steel plate, the upper crossbeam is a fixed crossbeam installed at the upper end of the main engine. The middle crossbeam is a movable crossbeam connected to ball screws through ball nuts. The middle crossbeam is also a key component for loading. Sensors are installed at the lower end of the middle crossbeam, and one end of various test attachments is also suspended above the middle crossbeam. The lifting and lowering of the middle crossbeam can generate tension and pressure.

6Clamp body:The wedge-shaped structure used for tensile testing is made of cast steel blanks, with one side closed and the other side used for installing sliding card plates and clamping blocks, with surface electroplating. Divided into upper clamp body and lower clamp body, the upper clamp body is connected to the sensor installed on the movable crossbeam, and the lower clamp body is connected to the worktable.

7Mobile control box:Used for quickly lifting and lowering the moving crossbeam when adjusting the test space, it has multiple operation modes such as fast/slow and step, and can be freely attached and pasted to the easy to operate parts of the host.

8Framework pillar:The four pillars are made of electroplated bright rods, with two in one group, installed on the outside of the ball screw. The upper and lower ends are fixedly connected to the upper crossbeam and workbench respectively, mainly used for frame support and installation of surface buckle plates.

9Dust cover:Installed on the inner side of the portal frame to prevent the ball screw from being damaged by dust.

10Outer cover:Made of materials such as aluminum alloy and color steel, it is mainly used to cover the internal parts of the machine, making the appearance of the machine beautiful. In addition, it can also provide protection for the internal parts of the machine.

The high-temperature tensile testing machine is produced by Jinan Zhongyan and has guaranteed after-sales service.
