NORMA with good professional knowledge. If the mounted STRACK nitrogen-gas spring is used incorrectly or not for the intended application, menace: Dangers for the health Dangers for the STRACK nitrogen-gas springs and other property holdings of the operator, Dangers for the efficiency of the STRACK nitrogen-gas springs. For all operations at the STRACK side cam, the valid Ordinance on Industrial Safety and Health paragraph 3 has to be considered. Press, tool and peripheral devices have to be suited, prepared and adjusted for the application of the STRACK side cams. Attention: Before and during the service- and maintenance operations at the tool respectively at the STRACK cam there is an increased risk of accident. Therefore these operations may only be effected at cam units which are driven back. Seized cam units at faultless gas springs can cause an abrupt decompression. Thus they can be an injury risk. Damaged gas spring may not be used again. The exchange of individual parts has to be agreed with STRACK NORMA. STRACK NORMA GmbH & Co.

Page 6: Characteristics
These PowerMax cam units consists of: - cam retainer - cam body - driver with the corresponding accessories All PowerMax cam units are equipped with gas springs. In this system, nitrogen with a purity grade of ≥99.8 vol.-% is used as active fluid medium for the gas springs. The cylinder dimension, cylinder number and filling pressure (different at the diverse cam types) determine the reset force which is available. Please consider that all PowerMax cam units are the successful result of a long development work. The resulting advantages optimally develop at the full exploitation of the respective cam stroke during the work process; that means, the stamping- and benching operation of the cam unit should be carried out in the front end position. The complete exploitation of the cam stroke allows the maximal intervention of the active return and the therewith connected highest possible supply of retracting- and stripper forces (about 10 % of the pressing force). In the front endpoint of the cam stroke there is the maximal retraction of the gas spring. Generally applies: The construction and the resulting values, like assembly height and restoring forces, require that the cam unit is mounted in the front end position. STRACK NORMA GmbH & Co. KG · Königsberger Str. 11 · D-58511 Lüdenscheid · Tel +49 2351 8701-0 · www.strack.de... -

Page 9: Preparation Of Tool And Press
6. Preparation of tool and press Tool, press and peripheral devices have to be suited, prepared and adapted according to the indications of STRACK NORMA for the utilisation of the PowerMax cam unit. Drain off fluid (for example water or drawing compounds) well-directed by drainage. You have to take care that punching wastes don’t fall in or on the cam guidance. Cam slide and guidances can seize. Parts falling down can damage the guidances, hereby possibly the running life of the cam reduces. If there is a failure, the cam slide can’t be placed back in the initial position. 7. Shouldering The force distribution of the individual forces in the cams depends on the right shouldering in the tool and the cam angle. If the heights h1 and h2 (see the picture below) reduce in the tool, the forces of the shouldering can’t be completely absorbed.

Page 24: Information Of The Lock-Out-System 5654-Los
10.2.1 Information of the Lock-Out-System SN5654-LOS Distribution of force: The new developed lock out system makes it possible to fix the corresponding standard cam free of play in its front end position. In doing so, the cam body is screwed with the cam reception. The special thing is that the clamping screws act under an angle on the corresponding bearing face. That means the cam body is once pulled by the divided (resulting) force against the prismatically arranged guide rails and at the same time is pulled against the pressure piece. Now the cam body is positioned free of play exactly in its front end position and is prepared for addi- tional machining. Please consider that the Lock-out-System can only be used in dismounted standard cams. At the most Power-Max standard cams the fixing holes are partly covered, if the cam body is in the front end position. STRACK NORMA GmbH & Co.

Page 30: Standstill And Storing
For the transport or storage of the tool with a mounted STRACK nitrogen gas spring system, it is reasonable to discharge the system pressure. Please consider that, according to the construction, components of the tool, during a longer storing, can uncontrollably be pushed together because of the lowering of the system p ressure of the gas springs in the cam units (Accident Prevention Regulation). Please check the system pressure of the gas spring before restarting the tool. If you have to increase the system pressure, act as described in chapter 11.2. 14. Maintenance Guide strips out of steel are hardened and normally are not submitted to any wear. If necessary these strips are adjusted during the mounting in the company STRACK to guarantee a low guide clearance. The fixing screws of these strips are secured with the bolt adhesive Z9093. The guide strips out of bronze with solid lubricant respectively sintered metal are submitted to a greater wear compared with the steel strips. The strips are produced in a narrow tolerance range. The exchange of these elements is thus effected without a new adjustment. If both guide partners are exchanged, the guide clearance has to be examined and if necessary has to be adjusted newly.

Page 31: Adjustment Of The Active Return
Loosen the fixing screws of the active returns (A) and of the adjusting wedge (B). Pull the adjusting wedge back and put the driver on the prism of the cam slide. After the installation of the driver on the cam slide push the active returns on the inserts of the driver and fix them by mov- ing the adjusting wedges in the direction of the arrow. Subsequently fix the screws in the reverse order. Fix the fastening screws of the adjusting wedges and the active returns, subsequently you secure the active return (A) and control the guide clearance with a 0.01 mm preci- sion calibre band. To avoid a tipping of the driver, both sides should be tightened in the same way. STRACK NORMA GmbH & Co. KG · Königsberger Str. 11 · D-58511 Lüdenscheid · Tel +49 2351 8701-0 · www.strack.de... -

Page 36: General Description Of Gas Springs
All STRACK gas springs are supplied with a quality certificate. COMPONENT CHARACTERISTICS Body Developed in one piece up to strokes of 125 mm. In higher strokes they have a tubular construction with a welded lid. As a difference with other brands, STRACK incorporates a threaded joint between the two elements that eliminates the possible fatigue factor in the weld bead. Stem Fatigue-resistant steels are employed, which have specific treatments that ensure a long useful life. STRACK offers the maximum quality MICROFINISH on the surface of all its stems, thus ensuring a longer service life by reducing friction and wear and tear in the seals.. Bushing It incorporates a scraper, an element that avoids the entrance of filth. All bushings are designeavoiding a metal-to-metal contact, recurring to self-lubricating guiding elements. Reference to gastightness, specific seals are used, which have been painstakingly tested and which offer a high working yield even near their maximum limits of use. STRACK NORMA GmbH & Co.

Page 39: Mounting Instructions Gas Springs
A 10 % nominal stroke reserve should be foreseen to prevent irrepearable damage in the gas springs and serious safety hazards. If possible fix the gas spring on the tool using the attachment holes at the bottom of the body or assembly accesories. Do not use threaded hole on the stem to fix the gas spring onto the tool. Do not install the gas spring onto the tool in such a way it makes a free stem ejection possible. The installation of a compressed gas spring is dangerous due to serious safety risks. The gas spring is to work completely perpendicularly to the contact surface. Lateral forces reduce the gas spring’s service life. Protect the gas spring from direct contact with liquid pollution: lubricants, cleaners and so on.. Protect the gas spring against mechanical damage or blows, especially the stem. Any imperfection may bring about a loss of pressure. Service temperature should not exceed 80°C. Higher temperatures will affect the seals, reducing the gas spring’s service life. Do not excede maximum filling pressures established for each Gas spring. Higher pressures will reduce both the gas spring service life and endanger its use. STRACK NORMA GmbH & Co.
