Spring Tensile / Compression Testing Machine testing machine is a special instrument for testing the deformation and load relationship characteristics of tensile and compression springs. It is suitable for working load test of tension and compression spring under a certain working length. The UnitedTest testing machine dedicated to spring testing machines (compression and tension tests for spring character or quality control) specialize in the development of testing machines, spring guide rods, accessories and software for springs of all types.

The Computer Controlled Spring Testing Machine mechanical structure, working principle, design, etc. learn from the advanced experience of foreign manufacturers, the machine structure, stiffness in strict accordance with the National Ministry of Machinery industry standards and designed for the precision detection of small springs, manufacturing. The machine is particularly suitable for a variety of precision-grade spiral springs, small disc springs, shrapnel and special spring detection, mainly used in spring production enterprises laboratory precision testing, spring use enterprises, quality inspection, metering, various types of institutions mechanics laboratory and other places.  

Key features:

 Preset different types of test methods, eliminating the hassle of setting up before each test;

 Four test methods, two types of test, can be connected to the three-color indicators to light the results;

 In order to ensure accuracy, repeatability under the premise of high-speed acquisition, high degree of automatic detection, one-click finish

 into the whole test process, greatly improve the test efficiency;

 Repeat batch detection can be set for a single type of spring, improving the efficiency of online detection;

 Electronic handwheel fast and slow loading, the minimum can achieve 1 m (micron) deformation movement;

 The display is industrial-grade 9.7-inch LCD screen (non-commercial), 1024 x 768 resolution,

 It has the advantages of full interface control, precise touch, long life, stable performance, wide viewing angle and small eye damage.

 Test control the whole process can be selected with a stylus, control click accurately, reduce mishandling;

 The main components are selected from foreign brands or domestic high-quality brands;

 Automatic judgment of data results, automatic analysis, real-time display;

Main testing function

The main functions of the full-interface touch system introduction (the following features are unique in the spring test industry):

★ A set of measurement and control software specially developed for spring pull test machine, which integrates data collection, motion control and data analysis, and has completely independent copyright.

compared with the previous generation of software, 

★ has better human-machine interactivity, higher test accuracy, stronger stability, higher test efficiency;

★ full-touch input mode of human-computer interaction, you can use click, double-click, keyboard input three modes, to achieve instructions, parameter entry and other operations, more in line with the current operating habits;

★ display sensor conversion data, can refresh the data in real time, can double-click zeroing, keyboard settings and other operations;

★ In response to the physical and mechanical deformation caused by springs with high rigidity and force values, the equipment can automatically compensate and correct the mechanical stiffness, making the measurement data more accurate.

★ adaptive display test waveform, the data change trend in the whole playback test process, is suitable for both rapid detection and laboratory accurate analysis.

★ button control is divided into one-click trigger and long-press trigger according to function, one-click trigger is used for full function control to achieve automatic control, and long-press trigger is used for motion control to improve safety and prevent mishandling;

★ has detailed test data for analysis, including measuring points, results, allowable upper limit, judgment, segmented stiffness, average stiffness, average softness, free height;

★ four test methods, two types of test, can set backhaul detection, reciprocating detection, etc.

★ the whole process of running at a uniform speed, to avoid the machine and deceleration caused interference to the test force, the real reduction of the test process;

★ system comes with a sample library, preset 20 kinds of specimens, users can set the corresponding parameters according to the needs, test can be directly accessed, improve test efficiency, reduce the difficulty of operation;

★ test data automatically stored, can store 100 sets of data, can view, print, export and other operations;

★ motion control sampling full digital sine wave control, smooth operation without impact, faster response;

★ based on fast sensor data conversion, high-speed parallel disk, one-click set compression height zero point;

★ load units include Newton (N), kN, kf, kgf, pound force (lbf), kip 6 kinds of international common units, users can set their own according to the needs;

★★★ protection measures:

★ overcurrent, voltage protection function;

★ load sensor two-way overload protection, 01 machine uplink in the process of two hooks touch, the load increases rapidly, when the controller detected more than the protection range, the machine immediately shut down;

★ displacement over-limit protection, 01 machine uplink, beyond the protection travel (test space), the machine immediately shut down, 2 machine downlink, over the limit travel (0mm, the machine immediately stopped;
