Spring Mechanical Property Tester Spring Tensile and Compression Testing Machine

I. Product Description:

This testing machine is manufactured in accordance with the technical requirements stipulated in JB/T7796-1995 "Technical Conditions for Spring Tensile and Compression Testing Machines". It is mainly used for testing the strength of various precision helical springs and elastic components, that is, testing the test force of the spring under a certain deformation amount or determining the test force of the spring at a certain height.

This machine can be customized to various testing equipment according to the requirements of users.

II. Main Functions and Features:

Hardware part:

Mainframe: Adopting a single-arm three-column structure. The mainframe frame is analyzed through mechanical finite element analysis, ensuring sufficient stiffness and strength of the frame. The transmission system uses zero-gap ball screw pairs to ensure the accuracy and durability of the test results. The mainframe frame is guided by guide columns to ensure the rigidity of the frame.

Transmission system: Composed of synchronous toothed belts, precision ball screw pairs, and guiding parts, etc.

Drive system: Step motors are used to drive the system.

Measurement control system: The test force measurement control system consists of high-precision load sensors, measurement amplifiers, A/D converters, and stabilized power supplies; the displacement measurement control system consists of photoelectric encoders, frequency doubling shaping circuits, counting circuits, etc. Through various signal processing, it realizes functions such as computer display, control, and data processing.

Safety protection devices: Over 10% overload protection, crossbeam limit position protection, overcurrent, overvoltage, overspeed protection, etc.

Software calibration part

Force value calibration: Using the three-point calibration method to make the test force values more precise and higher in accuracy.

Displacement compensation: The deformation caused by the sensor can be compensated. That is, the deformation caused by the sensor and the overall rigidity of the machine does not affect the accuracy of the displacement.

Safety functions:

Using the high-speed counter function, the upper pressing plate will automatically rotate at a speed of 300mm/min, then automatically set the displacement to zero, determining the lower pressing plate as the zero point of displacement. Then it will automatically return to a position 50mm away from the lower pressing plate and stop. This ensures higher precision of the testing machine and reduces the randomness of manual rotation.

Has limit function. In the tension and compression limit positions, there are limit protection switches for protection against accidental operation.

Has a force setting function, effectively preventing damage to the equipment caused by springs in unexpected situations.

Has displacement protection setting function

Has deformation protection setting function

Has an emergency stop function. If an accident occurs during the test, it can be stopped urgently.

Data printing content description

It can classify the test data of different test modes.

III. Control Software System:

This measurement and control software consists of functional modules such as dynamic communication, data acquisition, result observation, record query, data processing, and printing. It ensures the efficiency and accuracy of data acquisition, and the result output is convenient and fast.

In terms of appearance, this measurement and control software has the advantages of a clear interface, an attractive appearance, and convenient operation.

Different test schemes can be established according to requirements. Under one scheme, multiple batches can be established for batch testing. During the test, real-time data collection and real-time curve drawing are performed. The Access large database is used for data storage, facilitating resource sharing and reanalysis by users. After the test, the data is automatically processed and saved, and the test results can be viewed and printed at any time. The test report format can be changed according to the different requirements of users. The testing machine's data processing for test data fully complies with the standards of the spring testing machine.

Control method: Adopting multiple control methods, specifically as follows:

a) Set the test force P, and detect the deformation amount F of the spring.

b) Set the deformation amount F, and detect the test force P of the spring.

c) Set the test force P, and detect the remaining height H of the spring;

d) Set the remaining height H of the spring, and detect the test force P of the spring;

Ten detection points can be set. The pre-compression height of the spring can be set for pre-compression, and the pre-compression times can be set arbitrarily.

Batch testing greatly facilitates the use of users. After setting the test times, the testing machine will automatically test according to the set times, without the need for manual intervention.

Real-time high-speed approximation and low-speed collection are achieved to ensure the efficiency and accuracy of data acquisition by the testing machine.

The test speed can be set by oneself, and it will automatically return to the initial position after the test is completed.

Has an overload automatic shutdown function. A manual micro-motion feed device is configured. Under various load conditions, micro-motion feed can be achieved, facilitating calibration and fine adjustment of displacement.

It can automatically calculate the segmented stiffness P/ of the compression spring.
