Introduction to the main machine structure and main machine specifications of the universal material testing machine

　　 Universal material testing machine is also called universal tensile machine or electronic tensile machine.

Independent servo loading system, high-precision broadband electro-hydraulic servo valve, to ensure the system is high-precision, high-efficiency, low-noise, and fast response; independent hydraulic clamping system to ensure low-noise and stable operation of the system, and the test process sample is firm Clamping without slipping. Now let’s introduce the host structure and host specifications of the universal material testing machine.　　1. The mainframe structure of the universal material testing machine 　　Universal material testing machine is mainly composed of support, hydraulic control box, appearance force display, and electrical system. Some of its body has weighing, column, upper and lower flexural equipment, cylinder, frame, bottom plate, etc. The measuring surface is installed on the upper right side of the rack. Some hydraulic operations are installed in the lower part of the right side of the universal data testing machine frame, and the lower anti-folding equipment is installed on the top of the piston, with guide plates on both sides, which can maintain the same up and down movement direction of the anti-folding table. The anti-folding table is equipped with a ruler, two limiters are equipped with guide plates on both sides, and the anti-folding span can be adjusted arbitrarily. The drag roller can move up and down, so that it can achieve a balance effect when the force is applied. Two positioning columns are fixed under the crossbeam through U-turn bolts, with a ball head and a ball seat in between. The bolts are equipped with tension springs to balance the upper anti-flex equipment, and the drag roller can move up and down.　　 During the flexural test, the universal data testing machine can actively adjust the orientation according to the appearance of the test piece, so that the arc surface of the indenter is in a straight line with the test piece to ensure the accuracy of the test. Dust-proof rings are installed on the oil cylinder and the plane to avoid or reduce the dust entering between the piston and the oil cylinder when the piston rises and lowers, which will accelerate the wear of the two. In the compression test, as long as the compression pad and the lower plate are placed in the center of the anti-folding table, and the anti-folding equipment is removed under the beam, the compression test can be carried out. There is a sealing ring between the piston and the cylinder to avoid oil Overflow, an annular groove is opened on the top of the cylinder, and there is an oil leakage channel, through the plastic pipe, the oil overflows back to the oil tank.　　 2. The host specifications of the universal material testing machine 　　 host specifications: A. High-precision force sensor: 0~10KN 20ton. The force accuracy is within ±0.5. B. Capacity segmentation: Seven gears in the whole journey: × 1, × 2, × 5, × 10, ×

20, × 50, × 100%. The maximum resolution of full force is 1/1000,00 C. Power system: Taiwan inverter + AC frequency conversion motor + worm gear reducer + T-type screw. D. Control system:

Pulse Command control method is adopted to make the control more precise, and the speed control range is 5~250 mm/min. With fast coarse adjustment and slow fine adjustment functions. After the test, it will automatically return to the origin and be stored automatically.

E. Data transmission method: RS232 transmission F. Display method: UTM107+WIN-XP test software LCD screen display. G. Concise linear double correction system for the full range of one gear and precise full range of seven gears.

H. Luxurious test interface software can realize constant speed, positioning shift, constant load control mode plus multi-level control mode to meet common test requirements. I. Test space: Test width is about 400 mm (standard specification), walking space 800

mm (without fixture) (standard specification) J. Full displacement: Encoder 1800 P/R, 4 times higher accuracy, using LINE

DRIVE encoder has strong anti-interference ability and displacement resolution is 0.001mm. Small deformation: metal extensometer, resolution 0.001mm (optional)

K. Safety device: overload emergency stop device, upper and lower stroke limit device, leakage automatic power-off system, automatic break point shutdown function. M. Manual control method: a manual operation box can be added. The above is the mainframe composition and mainframe specifications of the universal material testing machine. I believe that everyone has a certain understanding of this after reading it. If you have any problems in the operation, you can call the company's service hotline through the webpage. The staff will answer you one by one. Welcome your call and support!
