1 High Thrust Air Cylinder PNEUMATIC POWER CYLINDER Generates high thrust of tons or higher from air pressure alone. The special mechanism allows for high speed operation. HIROTAKA MFG. CO.,LTD.

2 Overview The pneumatic power cylinder is a compact all-in-one unit that combines a hydraulic cylinder with the popular pneumatic booster developed by HIROTAKA SEIKI. The long stroke cylinder delivers high thrust and high speed performance for hydraulic operations. In addition to the standard model, the product line has been expanded with the introduction of a compact miniature series. Other models are available with switches, for easy output of motion signals, and with stop valves for emergency stop and inching motion. Clean room compatible products are available for applications where oil must be avoided. Head Cover Pressure Intensifying Piston Pressure Intensifying Tube Air Hydraulic Converter Pressure Intensifying Ram Middle Cover Hydraulic Piston Tie Rod Switch Hydraulic Piston Rod Rod Cover Flange Feature Generates high thrust of 1 to 40 tons via air pressure alone. Stroke can be lengthened. (100 mm or higher) Special mechanism allows for high speed operation. (0 mm at 0.5 seconds or less) Simple mechanism ensures trouble-free operation. Controllable by pneumatic valve alone. Delivers variable thrust by means of modifying the air pressure. Available with switch (Model with code "W"). Standard products allow for position detection using a timer, limit switch or other device. Models with switches deliver easy position detection by installing a lead switch to the hydraulic cylinder Available with valve (PCMV*, PCSV* and PCHV* models). Includes two valves to reduce piping labor. The user simply provides piping to the pressure source. Available with valve and switch (PCMV*W, PCSV*W and PCHV*W models). Includes valves and switch for optimum ease of use. The operation valved models can be installed Sandwich regulator for adjustment of the high thrust only, fall prevention valve for supply air disappears. Available with stop valve. Performs emergency stop and inching motion. (Usable only for long stroke motion during die replacement, and for high thrust during working operation.) 2

3 Mechanisms and Operating Principles Pneumatic Thrust Stroke High Thrust Stroke Return Drive Intermediate Stop The oil pressure piston advances at high speed when it supplies compressed air to port 3. The pressure is equivalent to the air pressure. The booster piston advances when it supplies compressed air to port 1. The oil of the hydraulic chamber is sealed up, and high oil pressure is caused by Pascal s principle, and the oil cylinder gets the high thrust. The booster piston and the oil cylinder return at high speed when it supplies compressed air to port 2 and 4. The cylinder suddenly stops when it supplies compressed air to port 4 at the same time to stop a atop valve in the middle of pneumatic thrust stroke. In the case of a return stroke, only stop a stop valve.

(If the punch must be separated from the workpiece by 70 mm during the removal and loading of the workpiece, the total stroke including the margin is 100 mm.) (2) Next, determine the high thrust required for the working air pressure. (If a thrust of 60,000N is required at 0.5 MPa, use the thrust table to choose PCH-08, which produces 62,7N.) (3) Determine the stroke required for the thrust derived in steps (2). (If the operation involves punching a material with a sheet thickness of 1.6 mm using a thrust of 6,000N, the theoretic thickness is 1.6 mm. However, this is increased to 5 mm to allow for the margin. Therefore, PCH should be chosen for this application.)

13 Oil Film Compatible Product Option model : PCM -B PCS -B PCH -B With the packings commonly used today, the oil leakage from the piston rod caused by the sliding of the hydraulic cylinder is not in itself categorized as "leakage". However, a single drop of oil can result in defective product for such operations as crimping operations and the forming of electronic parts, etc. These applications have created demand for oil film compatible products. The PCS and PCH series of products have been introduced in order to meet the demands of such applications. (Oil film compatible products are marked by the Internal construction The sliding of the piston (1) generates a thin film of oil adhering to the inside of the hydraulic tube (2). The film of thin oil flows down to the rod packing (3). The rod packing (3) seals the air pressure and cannot completely cut off the oil film. The oil film is discharged externally through the rod (4). Before the oil film is discharged externally, the attached oil seal (6) draws out and removes the oil film, which is then discharged externally through the drain port (5). Oil Piston Tube Rod Rod packing Drain port Oil seal About the 0il Film Compatible Product The definition "oil film compatibility" refers only to the piston. Separate countermeasure should be implemented for the drain port, SOL exhaust port, etc. SOL Exhaust port As shown in the illustration, the solenoid valve should be exhausted through a mist separator or similar device. (These drawings supplement the "Air Piping Application Examples" shown on page 12 and 13.) Recommendation : Exhaust cleaner (Maker : SMC, CKD, etc) Alternatively, install concentrated exhaust piping as a means of exhausting to the outside. Concentrated exhaust piping Drain port As shown in the illustration, install concentrated exhaust piping as a means of exhausting to the outside. Drain port Concentrated exhaust piping 13

18 Usage Precautions 1 About the Installation Direction Install the piston rod of Pneumatic Power Cylinder in a downward direction. Air release valve Air hydraulic converter Pneumatic Power Cylinder must be installed in the orientation shown in the illustration if you will need to install the piston rod of cylinder in a upward direction or sideways direction. The standard model cannot use it. The bubbles cannot be bled if the product installed in the improper orientation. Please contact us in advance. (Special model) Bracket Low pressure type Hydraulic piping Low pressure type Hydraulic piping Bracket Installation method of air-hydro converter When it install an air-hydro converter separately, install it in the equipment frame with the mounting bracket of each type. Arrange piping in low pressure hydraulic hose between cylinder and air hydraulic converter. In the case of upward direction type of PCH model, there is the type that an air release valve is attached in the tip of the rod. Release any internal air every one or two months. Low pressure type Hydraulic piping Bracket Air hydraulic converter Low pressure type Hydraulic piping 2 Hydraulic Fluid Quantity An oil level is located on the side of the air hydraulic converter. When oil falls down than an oil level, supply oil. 3 Punching Operations The pneumatic power cylinder differs from a typical hydraulic cylinder, in that there is a chamber containing oil and a separate chamber containing a mixture of oil and air. This causes the piston rod and ram to be expelled in proportion to the load factor of the workpiece, in the same way as an air current. As a result, the piston rod and ram can break. Breakage can be avoided by positioning the pressure intensifying stroke in a lengthwise position, and installing an external shock absorbing stopper made of a material such as urethane rubber. If a stopper cannot be installed, please consult with your distributor. Examples: Deburring machine for castings, destruction testing machine, drilling of thick objects. Low pressure type Hydraulic piping Bracket Upward direction Air hydraulic converter Low pressure type Hydraulic piping Sideways direction Install the converter regardless of the setting direction of the cylinder so that P3 port becomes the top. 4Precautions for Heavy weight JIG, DIE To mount the pneumatic power cylinder with a piston rod downward, it will have an affect with the slow return speed or the no-return on cylinder s operation when a load of JIG or DIE are high factor to the return thrust of cylinder. In that case, the problem may be improved with larger thrust if it will be supply more high pressure in P4 port. Then, it can enlarge return thrust with a support air cylinder without changing the air supply pressure as shown in Fig. 18
