Kiefer Tool excels at making exact specification replacement parts for companies that are using presses that are no longer supported by the original OEM. Kiefer Tool also specializes in manufacturing, machining and repairing components of stamping presses such as bolster plates (large blocks of metal) which are attached on top of stamping press beds. For more information on the design and function of a bolster plate (or bed), click here. When our technicians manufacture and install replacement parts for presses, whenever possible, they refer to engineering documents that detail how specific models of hydraulic, forging and stamping presses work, in order to determine material selections, optimal machining processes, finishes, geometrical requirements, tolerancing specifications and coordinate dimensions. For more information about purchasing replacement parts for presses and acquiring press maintenance manuals, click here. We fix hydraulic presses because these machines need constant maintenance. If ram seals are not replaced in a timely fashion, hydraulic or mechanical component repair services may be required. Kiefer Tool rebuilds hydraulic and mechanical presses because the never ending vibration and shock in the press can cause parts to deform, or in some cases, crack or break. Oil and fluid leaks are another reason why parts go bad. Hydraulic cylinders can fail due to aging rod bearings or weakening piston rods. Bushings may simple wear out. Repairs and regular maintenance comes with the territory of operating hydraulic and mechanical presses in an industrial setting. Manufacturers and stampers alike rely on Keifer Tool to keep the production equipment in their facilities operating at maximum efficiency.http://www.smadie.fr/how-to-sled-pull-with-a-manual.xml

Although Kiefer Tool repairs hydraulic machine components and hydraulic equipment for manufacturing firms all across the United States, most of the hydraulic press repair and large part machining work we do is for industrial companies in Ohio, Indiana, Michigan, New York and Pennsylvania. To maximize your hydraulic press’ uptime and reliability, it is important to take care of your company’s press by performing preventative maintenance work. To avoid hydraulic press problems and ensure optimal press functionality, be sure to follow the preventive-maintenance (PM) schedule provided by the hydraulic-press manufacturer, if this document is available. When manufacturing companies relay on hydraulic presses to stamp the products they sell, they rely on their operators to keep their presses running.When a hydraulic press simply stops working, the problem may be an electrical issue. If a piston is jerky, you may need to bleed the hydraulic system. If your manufacturing facility is having problems with double acting hydraulic cylinders, your maintenance crew will need to do some troubleshooting. If you factory’s hydraulic press won’t hold pressure, your firm’s mechanic may need to adjust the pump and valves. Dake has published a table online that lists the most common problems hydraulic press operators face, their inherent causes and possible solutions. If the frame of your hydraulic press is cracked, Kiefer Tool can weld it to fix it. However, you may have to consider eventually replacing your hydraulic press if the frame has cracked, if the press can no longer build up pressure or the press has continual electrical problems. Kiefer Tool builds and manufactures new hydraulic presses from the ground up for manufacturing companies in the United States. For the latest news on fixing hydraulic presses, click here.

We manufacture custom replacement parts for hydraulic presses. Since the 1940’s, we have known the impressive power of a workshop press, and its many advantages to those who use them. What is a manual hydraulic press. A manual hydraulic pres s is a device consisting of a hydraulic cylinder, typically fitted in a vertical orientation. This hydraulic cylinder contains a piston that has pressure exerted upon it by the confined oil pressure, generated by a hydraulic pump within the hydraulic system. When the piston advances, due to hydraulic pressure, it produces a compressible force on a stationary baseplate. The hydraulic press is widely used in the metal forming industry, and anywhere that large forces are required. Hydraulic Press Advantages There are a variety of uses of a hydraulic press as well as many advantages for using workshop presses. Simple Design Hydraulic presses are simple in design, which in turn makes them easy to operate. Plus, the hydraulic press will work effectively for many years if maintained properly. Since there aren’t many moving parts, upkeep is minimal, keeping costs down. High Volume A hydraulic workshop press, when properly set up, can be extremely beneficial for high-volume production increasing efficiencies and minimising waste within your facility.

Cost-Cutting Replacement parts for manual workshop presses typically are not expensive, are easy to find, and are not complex to fix. All components are readily available from RHTC Profi Press, or from a local industrial supply stockist. More Control With RHTC Manual Profi Workshop Presses, the ability for multi-action operation, either by hand or by foot, is a huge benefit. This is due to the fact you can eliminate the risk of damaging your machine or tools by readily and accurately being able to control the piston position. You can also control the pressure of the press to suit the job. The ram force, pressure release, the direction and the speed can all be adjusted to suit the requirements of the job. Smooth Pressing A workshop press, including a manual hydraulic press, will give you smooth, even pressure throughout the ram stroke. This allows accurate tonnages to be achieved at any point of the ram travel. Versatile The possibilities are endless when it comes to using manual workshop presses. This is because they can perform a huge variety of jobs within the tonnage range. Here are just a few examples: Bearing pressing Press braking Metal folding Punching Broken tool removal Forging Clinching Moulding Blanking Deep drawing Metal forming All of these processes require precise control and repeatability. Trust the Experts in Hydraulic Presses As you can see, there are plenty of advantages to using a manual hydraulic press for industrial purposes due to its simple working mechanism and use of quality components. However, the RHTC manual hydraulic Profi Press has many more benefits to offer.

To keep all of your shop's equipment in good working condition, try developing and implementing a written routine preventive maintenance schedule. An Ounce of Prevention Press operators play a big part in keeping the equipment running efficiently. Maintenance should address immediately strange noises, vibrations, or something that doesn't look right. The sooner problems are detected and corrected, the better, which can often mean a less expensive fix. Figure 1 Replace the ram seal when drops of oil are visible on the ram itself. The ram should run dry or with a very light, even film of oil on it. Bronze bushings should be greased as necessary. Sometimes it's the small preventive measures that keep a hydraulic press up and running. A daily maintenance check list should include the following: Check for oil leaks on all hydraulic lines. A small leak can turn into a big mess. Tighten leaky fittings and wipe off excess oil. Keeping a press clean will help pinpoint new leaks and keep the press running cooler.

Check the oil level and, if necessary, top it off. Most presses have an oil tag listing the type of oil needed. Check for loose bolts around the tooling area. Some dies can cause press vibration and shock, which loosen bolts. Check lubrication on guided platens. Some bushings have fittings that should be greased to maintain a thin lubrication film over the rod. Do not overgrease because this causes dirt to accumulate, causing the bearing to wear prematurely. Other bushings have a check valve-type fitting. These bushings have graphite impregnated into the bronze and require little maintenance. Never put grease into this type of bearing. Figure 2 Oil the motor oil nippler as recommended by the motor manufacturer. Check the oil temperature. When the press has reached its normal operating temperature, check the oil temperature. It should be around 120 degrees F. Check the ram. A press's ram should be moist but not dripping oil (see Figure 1 ). Check light curtains. One way to do this is to break the beam while the ram is traveling down. The press should stop immediately. Breaking the beam on the upstroke might not stop the press. Refer to the owner's manual for proper function. Oil Maintenance Besides performing daily maintenance, maintenance personnel should closely monitor a press's oil health (see Figure 2 ). Similar to an automobile, a hydraulic press can't run optimally on low or dirty oil. Figure 3 Always replace the air-cooled heat exchanger's filter screen when it's dirty. Keeping a press's oil in new condition is fairly easy to do. Dirt and heat are the principal enemies of a hydraulic press. Not maintaining the proper oil levels and quality will rapidly reduce the life of a machine. The ideal operating temperature is approximately 120 degrees F, which can be maintained by air or water coolers. Probes are inserted into the oil reservoir, and its temperature is maintained with a thermostat. Air coolers use a radiator to separate the heat with an electric fan.

Water coolers use water or gylcol. The radiator should always be clean (see Figure 3 ). Its vanes tend to collect dirt and dust, which prevent the airflow from traveling at maximum capacity. Attaching an inexpensive filter such as one used in heating and air-conditioning units to the heat exchanger will help keep the unit clean. Water-cooled systems work similarly, except water instead of air travels through the vanes. Three primary methods of cooling with water are city water, rooftop-mounted exchangers, and chillers. Running city water through an exchanger can be expensive and has a tendency to rust the exchanger. Also, many municipalities discourage using city water because of local water restrictions and codes. To inspect water-cooled heat exchangers, remove the end caps and check to make sure the passage is clear. Flush with cleaning solvent if necessary. Rooftop-mounted units can collect dust and dirt, which may clog the exchanger and cause rust if there is no rust inhibitor in the water. Placing a filter in the water line removes most fine particles. Again, inspect this equipment yearly. Figure 4 The red-yellow-green dial located in the lower left corner indicates when to change the oil filter. Water chillers are an efficient method to dissipate heat because the inlet temperature can be adjusted and antirusting agents can be added to the water. A yearly equipment inspection is recommended. An oil sampling should be performed yearly. Hydraulic fluids should be sampled and tested to ensure contamination and fluid properties are within acceptable levels. This sampling shows how many different-sized particles are in the oil, if the oil has water in it, and the oil's lubricity properties. In most cases, it's unnecessary to change the oil, but certain chemical additives may be needed to restore lubricity properties.

A sampling also determines if oil filters are being changed at proper intervals and if the correct filtration micron level is being achieved (see Figure 4 ). Simple hydraulic systems require code 10 filters. More complex systems with proportional or servo valves require code 03 filters. Electrical Maintenance Although modern electronics are reliable, they don't last forever. Coils on valves normally have a life cycle of approximately 3 million strokes, and relays have a life cycle of about 1 million strokes. Replacing them before they fail eliminates or reduces hours of troubleshooting and downtime. Installing an hour meter and a nonresettable cycle counter helps maintain accurate records and assists with scheduling maintenance. Control wiring should be checked annually to ensure all connections are tight and the wiring is in good condition. Loose wiring should be placed in wire ways or tied with wire ties (see Figure 5 ). All spare or unused wires should be capped off or removed. Any dust or dirt also should be removed from enclosures. Figure 5 Be sure to check the electrical cabinet for any loose wiring. Keeping your hydraulic press clean helps keep it in good working order. Never put off a problem for the next person to report or repair. Preventive maintenance is a small price to pay to keep your press running.View the Digital Edition Easily access valuable industry resources now with full access to the digital edition of The WELDER.
