3. Introduction 1

4. INTRODUCTION One of the earliest common machine tools is the hydraulic press. It is a machine press that uses a hydraulic cylinder to generate compressive force. It uses hydraulics to mimic a mechanical lever and was also known as a Bramah press after its English designer, Joseph Bramah . Modern hydraulic presses can sometimes be more effective in settings where mechanical presses have historically been more common. The performance and dependability of modern hydraulic presses is good.

5. INTRODUCTION (CONT’D The ability of hydraulic presses to perform has been improved by new fast acting valves, electrical components, and more effective hydraulic circuits. Forging, clinching, molding, punching, deep drawing, and metal forming processes are frequently performed with hydraulic presses. Compression tests are used to analyze how a product or material responds to compression, squashing, crushing, or flattening by evaluating how the material behaves under a compressive stress. It gives information on the integrity and safety of materials and products, assisting manufacturers in ensuring that their completed goods are fit for purpose and produced to the highest standards.

6. PROBLEM STATETEMENT This project is to show the application of hydraulic press in compression testing of: Aluminum C arbon steel Brass .

7. AIM OF STUDY The main purpose of this study is to use the hydraulic press to perform a compression test to determine the yield stress of some samples.

8. OBJECTIVES OF STUDY The main objectives of this project are namely

9. SCOPE OF STUDY

12. LITERATURE REVIEW Author Study Findings/ Gap Malachy et al (2011) Design, Manufacture and evaluation of a 30-ton Hydraulic Press The machine subjected two compression spring of 9N/mm to compression test with change in length of 300mm using a Load of 10KN The machine performance didn’t meet its design specification.

13. LITERATURE REVIEW Author Study Findings/ Gap Nwankwojike and Chukwunonso (2017) Development and evaluation of a Manually operated Hydraulic Press and pull machine. The machine was analyze with a load of 1000N. Its shows a deflection of 4.367 e 3 mm The machine is only useful for small and medium scaled workshops.

20. MACHINE COMPONENT Hydraulic cylinder A hydraulic cylinder, also known as a linear hydraulic motor, is a type of mechanical actuator that delivers a single force during a single stroke. Pressurized hydraulic fluid, which is commonly oil, provides the hydraulic cylinders with their power. A piston and piston rod coupled to a cylinder barrel make up the hydraulic cylinder, which oscillates back and forth.

21. MACHINE COMPONENT Hydraulic Hand Pump A hydraulic hand pump uses direct personal effort to transfer hydraulic fluid under pressure. It is an apparatus that transforms mechanical energy into hydraulic energy (hydrostatic energy i.e., flow, pressure). It produces flow with sufficient force to counteract the pressure brought on by the load at the pump outlet.

22. MACHINE COMPONENT Pressure Gauge A pressure gauge is a mechanical instrument designed to measure the internal pressure and/or vacuum of a vessel or system. Pressure Gauges are offered in a variety of styles, sizes, and wetted part materials to meet the demands of standard and special applications

23. MACHINE COMPONENT Steel Frame The hydraulic cylinder, hydraulic hand pump, and pressure gauge are all supported by this frame. The upper cross beam, heel block, setting plate, upper plate, and under plate make up the frame, along with the post, press bed frame, base section, and lower cross member. Bolts, nuts, washers, and lock washers are used to secure the various components together.

32. Conclusion and Recommendation 5

33. The compression test carried out was able to determine the yield stress of the three samples of brass, carbon steel and aluminium . This test showed that CONCLUSION

34. It is also recommended that the safety precaution be followed while performing the compression test. RECOMMENDATION The hydraulic press should be implemented into the mechanical engineering world because it makes works that involve high pressure to be performed easily and quickly . This compression test should be implemented in every material production industry to determine the maximum stress of materials
