Introduction

 KJ-WDW-300D microcomputer control electronic universal testing machine


,introduction:

WDW - 300D is a new generation of microcomputer control electronic universal testing machine. Mainly used for all kinds of metal, nonmetal and composite material tensile, compression, bending, shear and peel, tear and mechanical properties test. System USES computer closed loop control, has the broad accurate loading speed and load range of load, displacement measurement and control have higher accuracy and sensitivity. This equipment is suitable for metal, adhesive, pipes, profiles, aerospace, petroleum chemical industry, waterproofing materials, wire and cable, textile, fiber, rubber, ceramics, food, pharmaceutical packaging, geotextile, film, wood, paper and other manufacturing and product quality supervision departments at all levels, and at the same time also applies to colleges and universities teaching demonstration work.


The design of the host machine with artistic appearance, easy to operate, stable and reliable performance characteristics, no pollution, low noise, high efficiency. The design and main auxiliary equipment matching, the structure for wedge translation type, manual rotation clamping, sample from additional force. Holding is convenient, reliable and not slip.


This tester using speed control high precision, stable performance of Taiwan east yuan company digital ac servo control system and motor as drive system; Specially designed timing belts reduction system and ball screw pair drive the machine moving beam movement; With Windows for operating platform based on the database technology control and data processing software using the virtual instrument technology instead of traditional digital tube, oscilloscope, realized the test force, test force peak, beam displacement, specimen deformation and test curve screen display, all the test operation all can on the computer screen with the mouse input manner, has the good man-machine interface, convenient operation; Cartridge in the PC machine in the double channel full digital programmable amplifier has enabled the real physical zero, gain adjustment and test force measurement automatic shift, zero and calibration, without any analog control link, the control circuit highly integrated, completely canceled potentiometer mechanical adjustment device, the structure is simple, reliable performance. The comprehensive application of the technology to ensure the machine can realize test force, specimen deformation and beam displacement and parameter of the closed loop control, which can realize constant force, constant displacement, constant strain, such as speed loading cycle, such as speed deformation circulation test. User can use PC machine expert system independent setting constant stress, constant strain, constant displacement control mode, all kinds of control mode can smooth switching between. SPC mode to meet the national standard GB/T228-2002 "metal material room temperature tensile test method", GB/T7314-1987 "metal compression test method" requirement, realize the accord with GB, ISO, JIS, ASTM, DIN and so on the many kinds of standard data processing, especially has good expansibility, treatment results can be ASCII code in the form of disk storage. For test data and analysis, database management, network transmission and post-processing provides convenient.


Because this machine realized the test process of automatic control and test results of information processing, can make the operation personnel convenient, independently set test SPC steps. In the tensile test, can make the experimenter clear observation of low carbon steel, cast iron, etc the whole test process. Through the in different curve segment of repeated loading, by force, displacement (deformation) curve, can direct validation hooke's law and observation cold work hardening phenomenon. For no obvious physical yield phenomenon of materials, can choose hysteresis ring method or gradually approximation method determination rules non-proportional extension strength. In the compression process, convenient for observation mild steel compressive yield phenomenon and strengthening phenomenon, cast iron compression failure process and the fracture shape.


二,Structure and principle:

Host from the beam, mobile beam and table through the post, ball screw connection into rigid desktop frame structure, Taiwan east yuan ac servo motor and ac servo control system installed in the table below, ac servo motor through the timing belts retarding mechanism drive double ball screw rotation, thus promote mobile beam do move in order to realize the sample loading (mobile beam and table are installed between compression, bending affix, may to the metal or nonmetal material sample was compression and bending test; mobile beam and beam are installed between the tensile affix, may to the metal or nonmetal material specimen tensile test). Force transducer installed in the bottom of the move beam, used to measure the size of the test force; Ac servo motor built-in displacement measurement system for measuring sample displacement, also can approximate instead of sample deformation; For some metal materials, testing machine configuration specimen elongation of special measuring device - extended meter, amplify meter of double clip clamps sample scale distance two, real time measurement sample scale distance two separation distance, namely sample deformation, microcomputer control test process, and realize the data processing and output.


三,working conditions:

1. The room temperature:10-35 .

2. Relative humidity 80%

3. Surrounding no vibration, no corrosive medium, without strong magnetic field interference.

4. Power supply voltage fluctuation not more than 10% of the rated voltage.

5. On solid ground level installation, levelness of 0.2/1000.


,performance and characteristics:

1. Adopt Taiwan east yuan ac servo motor and ac servo control system to control the experiment process, control precision and quality greatly improved, steady, high efficiency, low noise (low speed basically no noise) and control speed range greatly widened (0.005-400 mm/min), is advantageous to conventional materials of low speed test (metal, cement, concrete, etc.), and for non-metallic materials (rubber, etc.) high speed test, at the same time can also be used to when there is no quick adjustment test space, save auxiliary test time. The test speed to meet the present domestic all the usual metal and non-metallic materials testing speed requirements.

2. The timing belts, precision ball screw pair of "powerful" hand even of reduction mechanism so that the structure more concise, lively, the transmission efficiency greatly improved, the host next table position height and host height also fall subsequently, the outward appearance is more coordination.

3. The tensile and compression independent double space structure, convenient operation, to avoid the tensile and compression bending in the same space change of different test affix loaded down with trivial details.

4. But according to demand of different specifications of sensor, make the test range greatly widened to meet different test load measurement requirements.

5. Host appearance shell, modelling is easy, beautiful.

6. USES the advanced control technology, has the stress, strain and displacement three closed loop control mode, each control between ring can be automatically switching, and in every way to switch between when no impact to realize smooth transition, synchronous display test force, peak, displacement, speed, test condition, test curve, etc.

7. Can test force, deformation, displacement and speed control and maintain.

8. Can realize sample when clamping beam fast/slow lifting adjustment, flexible operation, arbitrary switching.
