Many lab-quality automatic hydraulic presses are now programmable, allowing you to make custom settings for specific jobs so that pressing the same piece of metal repeatedly takes less time and effort than it used to. This makes your work more consistent and efficient, but before you buy one of these fantastic machines, there are some things you should know about programmable hydraulic test presses in general and the features that come with each of them so that you can decide which one will best meet your needs.
Why Use A Programmable Hydraulic Test Press?
A programmable hydraulic test press can be used for various welding quality control and destructive testing applications. These include molding, clinching, forging, punching, and other welding operations requiring high pressures. They are particularly suited for large laboratory presses where large volumes of tests need to be carried out quickly to meet customer requirements. However, when selecting a programmable hydraulic test press, you'll need to consider different factors, including the maximum pressure rating, the size, weight, and portability of the unit, as well as the range of operating temperatures it is designed to work within.
Popular Methods of Programmable Hydraulic Testing
1. Bend testing
This method is best known for measuring ductility, or the ability of a material to deform and return to its original shape without breaking, by applying a load on the workpiece and then measuring the amount of deformation at various loads. Destructive Testing (DT) is often used as a quality control technique to examine samples of products or materials that are suspected of being defective.
2. Tensile testing
This assesses the strength and maximum elongation by measuring the force required to pull apart two ends of a sample and by comparing this measurement with those obtained from other samples under identical conditions. Destructive Testing can inspect welds for cracking, porosity, slag inclusion, distortion, or incomplete penetration to identify if they were made with sufficient skill and care.
3. Compression testing
This method evaluates compressive and elasticity strength and toughness by measuring the force required to push together two ends of a sample and can gauge how resistant it will be to fracture when subject to sudden impact. It also determines whether or not a metal has enough tensile strength to withstand fatigue without losing elasticity.
4. Nick break testing
This method analyzes joint fusion of the welds and ductility of both base metals by performing destructive tests and gauging their performance in bending tests. The nick break testing provides welding quality control through destructive testing and can gauge the performance of both base metals in bending tests. In addition, this type of test press is typically considered for industrial use because of its heavy-duty construction, which provides significant features such as wide range movements; high-torque capacity; ergonomic design; power levers for controlling large clamping forces; digital readouts for precise adjustments to position settings; quick release clamps.
Conclusion
A programmable hydraulic test press offers many benefits. It is used for welding quality control in large laboratory presses and has made processes easier and more efficient. These units can be programmed, allowing one to adjust the pressure at any time while running the tests. They also offer greater accuracy in determining welds that were done correctly. Just ensure that you invest in high-quality equipment that will last you for years.
