The 150 ton hydraulic press is the ideal shop press for manufacturing, auto repair and general mechanical work. Crafted from heavy-duty welded steel construction and designed to withstand years of usage in any shop environment.
It features a sliding ram pressing head with left/right movement for maximum workpiece flexibility, while its hydraulic system is powered by an electric motor to provide controlled ram pressure.
A hydraulic press machine's power unit consists of the engine assembly that supplies electricity for its pumping system. This typically includes a radiator for cooling the engine as well as air intake and exhaust systems; additionally it usually features a control panel/throttle, base or feet for supporting it as well as tank accumulators that help build and maintain pressure in actuators.
In most instances, an accumulator is outfitted with a fast-stroking device to quickly charge and discharge pressure when necessary. Furthermore, temperature switches may also be installed to shut the motor pump off when temperatures increase; additionally, pressure switches can help monitor and notify operators if pressure levels decrease dangerously low levels.
Hydraulic Cylinders are one of the primary components of any hydraulic press, typically functioning in dual action to deliver hydraulic oil to both sides of its platen. Tonnage refers to how much pressure this cylinder can deliver; this amount is determined by multiple factors including guide rails that keep the Slide Table parallel with Bolster Table and Daylight which measures distance from top of Slide Table to bottom Bolster Table as well as piston stroke length among others.
Utilizing hydraulic pressure, the cylinder produces linear actuation by pushing or pulling. The larger its rod inside is, the greater the force it can produce.
Cylinders come in various materials depending on their intended use and operating environment, with stainless steel often the material of choice when working in harsh mining conditions or other harsh environments. Furthermore, this choice can help prevent corrosion which could corrode seals and metal components of hydraulic systems quickly over time.
Hydraulic fluid enters and exits a hydraulic cylinder through ports located on each end of its tube and piston, as well as through two ports at either end. For safety's sake, each port must be tightly sealed as any leak could result in loss of valuable hydraulic fluid under high pressure. To make sure they're up for the job ahead, a hydraulic cylinder should be thoroughly inspected after every disassembly operation and repackaged for reuse after each dismantle session.
Visual inspection should include checking for damage that requires repair or replacement before beginning the rebuilding process, to avoid costly mistakes such as discovering broken components that go undetected until after assembly has begun. It's also wise to verify all necessary tools are present before commencing with repacking; any missing tool could delay or even halt your efforts - these include hydraulic cylinder rod scrapers, pick and spring pullers and action testers for testing the hydraulic cylinder action.
Hydraulic pumps are devices used to generate an uncontrolled flow of pressurized liquid through a pipe (known as "drive pipe"). When building one, the appropriate materials must be selected; stainless steel is often chosen due to its superior strength, durability, and corrosion-resistance; cast iron may be utilized due to its cost effectiveness and good mechanical properties while alloys like bronze and brass provide low friction properties as well as resistance against wear and tear.
Hydraulic cylinders tend to move more quickly than pneumatic ones because they use pressurized fluid instead of air pressure as power transmission source. But in order for it to function efficiently, its fluid must meet certain criteria; otherwise it may cause increased friction among its moving parts, ultimately slowing or stopping operation altogether.
Increase the pressure applied to a hydraulic cylinder by adding liquid or installing a higher-pressure spring, such as by increasing its volume or volumetric flow rate. However, be wary as an increase in pressure can make your hydraulic cylinder dangerous to work with and lead to overheating or leaks in operation.
Hydraulic hoses are key pieces of equipment in any hydraulic system, and their failure can be very costly. Failure is often due to improper installation or constant movement like being attached to a forklift or flatbed truck. For proper crimping of hydraulic hoses it is necessary to purchase an affordable hydraulic crimper online like those sold by Parker 4300 tube fitting catalog; you may also find this useful in having specific crimp specifications on hand.
Once the hose is of appropriate size, it can be cut with a hose saw to length. Marking its insertion depth using a line helps ensure when installing crimp fittings they line up perfectly with this mark. Also be sure to clean both ends post cutting to eliminate contamination and assembly failure.
Step two is to assemble the hydraulic hoses and connectors. First, take threaded piping and connect it to plastic tubing before attaching the caps with glue. Step three requires creating the plunger with more plastic disks attached to hosed section before finally inserting hose and testing for leaks - if none exist you're all set to start using your 150 ton hydraulic press!
Hydraulic Hose Fittings
Utilizing fittings that match both the type and size of hose is paramount to creating an efficient hydraulic hose assembly. In particular, over- or undersized fittings could compromise seal integrity or lead to leaks; additionally, their material should be compatible with the working hydraulic fluid - typically petroleum-based or water-based depending on its properties.
Next, the hose and fitting must be assembled. Field attachable fittings offer the easiest method, featuring threaded stems with mating sleeves or ferrules that easily snap together; these fittings can be ideal for emergency repairs or occasional use on equipment not generally kept operational - though they do require more time for assembly than their crimped counterparts.
If you opt for a crimping machine, select and lubricate an appropriate die set for the hose and fittings you intend to crimp. Marking its insertion point with paint marker or another means will help ensure it fits securely within the machine.
Make sure your hoses are long enough to have a minimum bend radius at their connectors, as short ones cannot provide sufficient flexibility to withstand axial tension, leading to failure. Furthermore, long enough hoses should allow for expansion and contraction due to pressurization (a pressurized hose can expand/contract by up to 4%) which should ensure optimal results.
Hydraulic presses are integral parts of many industrial and manufacturing operations, used for tasks as varied as stamping, forming metal powder products, cold extrusion, forging, straightening, flanging, punching and light stretching.
Hydraulic presses utilize liquid as the working medium and, thus, are capable of creating much higher forces than mechanical ones. Their capacity ranges from several tons for manual models all the way up to thousands when powered by motor.
Hydraulic presses can be modified and tailored to the unique production or assembly applications they are used in, by changing pressure, stroke speed and process position settings. They can even be used to produce large components requiring substantial deformation.
C-frame hydraulic presses offer easy operation due to having open piston and cylinder pistons and cylinders on both sides, but have lower levels of rigidity than welding frame presses.
Redline 150 Ton Hydraulic Shop Press features an electric hydraulic pump for heavy-duty pressing, an adjustable ram cylinder that moves left and right, a crank style carriage winch for quick adjustment of middle carriage and tonnage gauge so users can see exactly how much pressure is being applied - an invaluable addition to any workshop or garage!
