What are the models of spring test machines? What are the factors that affect the life of spring test machines?

Spring testing machine is a specialized instrument for testing springs. After the spring is produced, it must pass strict testing before it can be put into use, because most of the springs are the main components used on machinery and vehicles. It is concluded that the main function of the spring test machine is to test and analyze the tensile force, pressure, displacement, stiffness and other strengths of the spring tester, such as tension springs, compression springs, disc springs, tower springs, leaf springs, clamp springs, leaf springs, composite springs, gas springs, mold springs, opposite-sex springs and other precision springs. So what are the models of spring test machines? What are the factors that affect the life of spring test machines? Let’s take a look together.

1. What are the models of spring test machines?

1. The vertical manual spring tension tester is the simplest one among the tensile machines and is also a grade-level one. Its measurement range is less than 5000Nmm. When it operates, it transmits torque and torque angle through an angle sensor and a torque sensor. It adopts amplification, acquisition, and closed-loop control to make the display stable, high accuracy and convenient to use, and has the characteristics of stable rotation, low noise and long service life. It has the function of overload protection, the minimum reading value of torque is 0.1Nmm, the minimum reading value of torque is 0.1 degrees, the test machine level is level 1, and the power supply is 220v, 50HZ.

2. The horizontal spring tension tester mainly conducts torsion tests on various torsion springs and worm springs. Determining the torque of the spring at a certain rotation angle, or measuring the rotation angle of the spring at a certain rotation torque, can also be used for torsional performance tests of other elastic components and friction mechanisms. This spring test machine is mainly used in spring manufacturing plants, electrical appliance manufacturers, power machinery factories, colleges and universities and related scientific research units. Word amplification, acquisition, and closed-loop control are adopted to make the display stable, the accuracy is high and the use is convenient. High-precision reducer, with smooth transmission, low noise and long service life; large LCD display in real time, can display test torque, angle, peak value, etc., with generous appearance, easy to use, simple operation; it has automatic overload protection.

2. What are the factors that affect the life of the spring tester?

As a high-precision detection instrument, the spring tester must be checked when purchasing. The internal configuration directly affects the service life of the spring tester itself. In many cases, the spring tester is damaged by a certain part of the components, which causes the spring tester to fail to operate.

1. The host stiffness is the maximum amount that the host can withstand. Don’t buy ones that look very small in the same tonnage. After using it for a period of time, it will deform and be discarded directly, and it will not work at all. Therefore, remember to handle this carefully when choosing this.

2. It is the ball screw. The bead screw is the key to the spring test machine. It can be operated because of its equipment. It plays a driving role in it. If you buy it, you must make sure it is a ball screw, not a trapezoidal screw.

3. In terms of motors, many people choose domestic motors, mainly cheap, but their quality and accuracy are relatively inferior to imported motors. So you must remember this point that the motor must be imported servo motors, because this motor has a good reputation and quality in the testing equipment.

4. Spring tester fixtures and fixtures do not have to be hydraulic, unless the weight of the sample measured by your spring tester is particularly large, because this is difficult to operate by manual fixtures, and manual fixtures are different. They are relatively convenient to use and more reliable to operate. Therefore, the most popular one in the fixture industry is manual fixtures, which are more user-friendly to the equipment.

In fact, our common types of spring testing machines include vertical manual spring tension testing machines and horizontal spring tension testing machines. Generally speaking, we encounter more of these two types of test machines. The above is the relevant introduction to the model of the spring testing machine introduced to you and the factors that affect the life of the spring testing machine. I hope it can help you.
