There are many people doing universal testing machine. If you want to choose the one with good quality and high price, you can take a look at Shanghai Farui. The main configuration of fr-103c servo tensile testing machine is as follows:
one high-precision imported American brand sensor
(imported sensor, high precision, good repeatability, no zero drift and rable. The domestic sensor has low sensitivity, can not be cleared, and the deviation of each test data is large.)< 1 set of imported servo control system
1 set of AC imported servo motor
(the imported servo system is a feedback control system through mechanical displacement or displacement speed and acceleration. Its function is to make the output mechanical displacement (or rotation angle) accurately track the input displacement (or rotation angle). Compared with ordinary motor, it has low power consumption, large torque, wide and accurate speed control, High and low running torque is equal, with servo closed-loop control, high-precision braking. Generally used in automation, precision instruments, precision equipment.)
Taiwan high precision ball bearing + ball screw 2 sets
(non trapezoidal screw, trapezoidal screw has large noise, easy wear, large clearance and low precision. The cost of high-precision ball bearing + ball screw is several times higher than that of ordinary trapezoidal screw. It has the advantages of small clearance, high precision of moving distance, uniform linear motion of motor, small friction, small noise and rability
the motor is directly equipped with a set of structure of Taiwan subtraction machine
(adopted by some companies, the belt plus large and small flywheel structure is easy to slip, and the two sides can't be synchronized, so it will often get stuck. Our company is a subtraction machine, the ball screw servo motor adopts the overall structure, and the synchronous belt control reces the transmission error or slip)
the main components of the circuit are imported

the difference of tension range determines the different sensors used, which also determines the structure of the tension machine, but this item has little effect on the price (except the door type). For general flexible packaging manufacturers, the pull range of 1000 kg is enough. Therefore, it is also decided to adopt the single arm type. The structure corresponding to the single arm type is the door type structure, which is suitable for relatively large pulling force, such as one ton or more. So flexible packaging manufacturers basically do not need
the problem of test stroke
according to the needs of flexible packaging film, test performance and requirements, the stroke is 600-800mm. If the material elongation exceeds 1000%, the stroke can be 1000 or 1200mm
standard configuration problem
there are three basic configurations of intelligence: host, microcomputer and printer. If the microcomputer has strong function, it can print directly. In addition, it can also be equipped with ordinary computer. With the help of computers, complex data analysis can be carried out, such as data editing, partial amplification, report format adjustment, and group style statistical analysis
output results
the output results of test results can be set arbitrarily: maximum force value, elongation, tensile strength, constant force elongation, constant force elongation, yield strength, elastic molus and maximum test force. This can be said to be the most comprehensive result of microcomputer operation
in the experimental projects
flexible packaging requires a multi-purpose pulling machine, that is, on the basis of different fixtures, it can be used for stretching, compression, bending, tearing, shearing, 180 degree peeling and 90 degree peeling tests
in addition to the above items, there are some high-end tensile machines on the market, which can also test the friction coefficient because of their high sensor accuracy (some up to one in 200000)
main mechanical configuration of the proct:
transmission, including lead screw transmission and rack transmission, the former is expensive, used for high precision and high repeatability; The latter is cheap, low precision and low repeatability
lead screw plays a decisive role in the measurement of tension accuracy. General ball screw, trapezoidal screw, general screw. Among them, the ball screw has the highest accuracy, but its performance depends on the operation of the computer servo system, and the price of the whole set is relatively expensive. The precision required by soft packaging can be achieved by using general lead screw and trapezoidal lead screw, that is, 0.5-1% precision
transmission. There are gear transmission and chain transmission. The former is expensive and used for high precision; The latter is cheap for low precision
the main cost of the sensor lies in its service life. Photoelectric inction is one of the most advanced technologies, which can be used for more than 100000 times in general. However, the sensor adopted by Shanghai xinrenda Instrument Co., Ltd. is American, which has high precision and can be used for more than 150000 times in general
test speed
some of the equipments on the market are in the range of 10 ~ 500 mm / min, and some are in the range of 0.01 ~ 500 mm / min. the former generally uses the ordinary speed control system, which has low cost and rough influence on the accuracy; The latter uses servo system, the price is expensive, high precision, for soft packaging enterprises, choose servo system, speed range of 1 ~ 500mm / min is enough, so it does not affect the accuracy, the price is within a reasonable range
measurement accuracy. The accuracy includes force measurement accuracy, velocity accuracy, deformation accuracy and displacement accuracy. These precision values can reach up to plus or minus 0.5. But for general manufacturers, 1% accuracy is enough. In addition, the force resolution can almost reach 1 / 250000. Error causes
1. The error caused by the incorrect installation of the testing machine
the uneven installation of the testing machine will increase the friction between the moving parts, affect the vertical installation, and bring error to the testing machine
(1) if the main engine is not installed horizontally, there will be friction between the working piston and the working cylinder, and there will also be friction between the guide wheel between the working platform and one side column of the testing machine, resulting in errors, which are generally positive errors, and the errors decrease with the increase of the load
(2) the installation of the dynamometer is not horizontal
if the front and rear installation of the dynamometer is not horizontal, friction will be generated between the penlum shaft bearings, and the error is generally negative
considering the above two factors, the characteristics of errors are that they have great influence on small load and little influence on large load< (1) the friction resistance of the main engine
the friction resistance of the hydraulic testing machine mainly occurs between the working cylinder and the working piston. In addition to the installation is not horizontal factors, there are dirt in the cylinder, oil viscosity is too large, will also cause increased friction resistance. In addition, the improper position of the guide wheel of the working platform will also increase the friction with one side of the column
(2) friction resistance of dynamometer part
there are many reasons for friction resistance of dynamometer, such as dirt between dynamometer cylinder and dynamometer piston, too high viscosity of oil, high friction of driven needle on indicator device, oil stain and dirt on gear rod or too tight upper limit plate of gear rod, wear and fracture of dynamometer piston belt, etc
error elimination method
for the occurrence of the above errors, it is necessary to first check whether the testing machine is installed horizontally, and level the main engine with a frame level in the two mutually perpendicular directions of the outer ring of the working oil cylinder. For the dynamometer, adjust the front and rear level of the dynamometer on the front of the swing bar, align and fix the edge of the swing bar with the inner scribe line, and adjust the left and right level of the body with a level ruler against the side of the swing bar. Oil can be drained to clean the viscera of the oil cylinder and the oil with appropriate viscosity can be replaced. If the driven needle friction of dynamometer indicator is too large and the gear rod is too dirty, gasoline can be used to clean and adjust the pressing screw and the upper limit piece of the gear rod, and replace the belt on the dynamometer piston. All these can achieve the purpose of eliminating the error and make the testing machine reach the qualified use state
