The machine worked without any challenge as there was no distortion, deformation, no weld failure, no leakages and the operation of hydraulic pump, ram and pump mechanism was quite satisfactory under the varying loads. It was noted that bending of this pate started at a pressure of 15 bar and maximum bending was taken to be 20 bar.
Other press operations which the machine could perform include but not limited to deep drawing, cup drawing, shallow drawing and stamping. Figure 3. The fabricated hydraulic press machine. Figure 4. Figure 5. Figure 6. A hydraulic press machine has been developed. The machine was fabricated using locally made materials. The machine is capable of performing various press works. Various machine parts such as pump, hand lever, ram assembly and pressure gauge worked effectively and efficiently.
Some of press work operations performed on the machine include: bending, punching, drawing and stamping. The machine was also used to press sleeves of internal diameter of 85 mm and external diameter of 89 mm into the cylinder of an automobile engine block at a pressure of 15 bar.
Performance evaluation of the machine shows that it can compete favourably with imported press machines of the same designed capacity. The development of more of this important workshop machine is expected to boost our local manufacturing industries.

Methodology In achieving the aim of this work, component parts of the machine were designed using various design equations. Machine Frame A frame is a structure on which main units of a machine tool are assembled.
Determination of Tensile Stress Due to Stretching of Bolt Initial tension in a bolt based on experiments may be found by the relationship in Equation 4 as given by Sumaila and Ibhadode, Detailed Drawings of the Machine The detailed Isometric view and Orthographic view of the machine are shown in Figure 2 respectively. Machine Fabrication Processes The various processes used in the fabrication of this hydraulic press machine include: Measurement, Marking out, Cutting, Drilling, Welding, Fastening, Grinding and Painting.
Assembly and Welding of Machine Components In welding various components of this machine together, electric arc welding technique was used because of the ease of concentration of heat. Conflicts of Interest The authors declare no conflicts of interest.

I wish I had a picture of my homemade press to share but it was never anything I gave much thought to, so I never took one. I hear you on the vise press, I used to use a length of pipe on my vise handle to get more squash out of it. Im still in playtime mode with the new toy, bent some 10mm square steel rod into hanger brackets for my bicycle, nicely out of the way on the garage beams now.
Introduction: Build a 10 Ton Hydraulic Press. By petercd Follow. More by the author:. About: general bloke type of tinkering More About petercd ». A press is something you dont use often in the home garage, but when you need one, nothing else will do. I needed to straighten a bent bike axle, and after pricing one in a machinery shop I've bought a car for less, admittedly that was in though , I figured I could make one, I mean how hard could it be?
Pretty easy it turns out, all you need is some big bolts, heavy duty steel and a hydraulic jack, after some labour in the shape of welding, drilling, cutting and grinding, a 10 ton press appears. Some research on the topic of presses soon revealed some aspects of design and usage functionality: Some presses had winches to raise the lower work table and had never used that function.
Most presses in the 10 ton range had fixed hydraulic rams, no side to side movement, so everything had to be centered for it to work. Bench presses were limited in their use due to small size and large floor standing ones were heavy and had wasted space. A return spring speeded up the process and made working with the weight of a 7kg jack much easier.
A gauge was nice to have but not a necessity. My intended use was to straighten a bent axle so a gauge wasnt needed and a medium size unit between bench and floor sizes would suit me just fine. I also wanted the bottle jack to be removeable in case it was needed to do duty elsewhere.
A small amount of welding will be needed on the upper and lower bottle jack brackets and also on the stabilizer feet. With that in mind, all the cautions regards welding apply, ie long sleeves, proper welding gloves and helmet for arc welding. Bear in mind that you can get uv burns on the neck area that isnt covered by the bottom of the helmet, especially when welding objects on the floor.
Proper footgear safety boots or at least leather shoes while welding is also a must, its hard to get neat welds while dancing around in slip slops with hot molten metal drippings on the toes. Its very advisable to weld outdoors due to the fumes, be very cautious of welding on gavanised metal because it releases clouds of white toxic smoke.
With that in mind, eye and hearing protection is a must. An angle grinder with a cutoff blade makes a racket which soon causes a ringing in the ear without proper protection, it also sprays a shower of sparks which can bouce back off nearby objects, beware the hot spark bouncing back off a wall over the top of your safety goggles , its not a fun experience.
A pair of work gloves is good insurance against a wire brush if it should slip, as well as cutting down on the vibration being transmitted to your hands. With that in mind, eye protection is a must, its also a caution on the outside of the blu-mol box. When the hole saw binds it can exert force on the work piece, so said work piece should be safely clamped to revent rotation.

Tea-light Lantern by ruths in 3D Printing. Other forms of processing including pushing stock through rollers that bend it into a simple curve. There is no fixed machine design procedure for when the new machine element of the machine is being designed a number of options have to be considered.
When designing machine one cannot apply rigid rules to get the best design for the machine at the lowest possible cost. The designer who develops the habit of following a fixed line of steps for designing the machine or machine elements cannot come out with the best product. Figure 1 shows the design details of the hydraulic pipe bending machine. This project is designed with. Here we are placing the hydraulic bottle cylinder on the based plate, and the pressing tool is fixed in the hydraulic piston rod end.
The working table is placed on the op of the supporting frame. It can be adjusted according to the work piece height by adjusting the lock nuts which is placed at the either side of the work table. The hydraulic bottle cylinder is working with the help of supply of oil from the pumping rod side. Here we have to tight the pressure relief valve then to start pumping with help of pumping rod by pumping, the oil will supply to push the piston upward direction by this pressing tool will move through it to pressing the workpiece.
By the completing the bending process we have to release the pressure relief valve then the piston comes it original position. Used in small and large scale industries and cable wire making industries etc.. This work has provided a n excellent opportunity and experience, to use limited knowledge.
It has gained a lot of practical knowledge regarding, planning, purchasing, assembling and machining while doing this project work.
