2 Wedge clamp, double-acting for dies ith tapered clamping edge pplication: safe clamping of dies ith a tapered clamping edge for clamping of dies on a press bed and slide for clamping of dies in injection moulding machines Hardened edge clamping insert ushings Design: Double-acting edge clamp for clamping dies on a press bed or slide or for clamping dies in injection moulding machines. The edge clamp consists of a hydraulic block cylinder and a piston guided in a housing. The clamping bolt is proided ith 20 beel to clamp on the beelled clamping surface of the die. ased on the internal design of the edge clamp and the 20 clamping beel the system is proiding internal friction. For reasons of safety and in order to comply ith the specifications of the Machinery directie no. ML98/37/EG, hydraulic pressure must alays be maintained. When upper dies are clamped by edge clamps, they must be secured mechanically hen maintenance ork is carried out. Retrofit: In many cases, existing dies can be standardised by adding edge inserts. Max. hardness: 50 HRc. The occurring transerse forces must be absorbed by bushings to be drilled into the fixture plate (see table for accessories) Please note: In case of incorrect operation of the edge clamping element, the clamping bolt may fully retract into the guide housing and thus cause the upper die falling off the slide. Special features: aailable in sizes beteen 25 kn and 1250 kn high functional reliability ensured by position monitoring and an automatic cycle rugged and ell-proen clamping element ith high degree of safety and long serice life The greasing interals (high-temperature grease) should be scheduled in accordance ith the operating conditions. Greasing of the clamping bolt should only be made ith the elements being retracted. Clamping elements ith edge clamping bolt must be protected against dirt, scale, sarf, coolant, etc. by means of a suitable coering. Dies clamped by means of edge clamping elements are subject to transerse forces hich may be strong enough to displace them. Therefore, location pins or suitable limit stops should be proided, in order to keep the dies in their correct position. When using edge clamping elements on the press slide, it is recommended that multiple-circuit hydraulic supply of the clamping elements and pilot-controlled check ales are used in the clamping lines for securing hydraulic clamping. Clamping circuit Safety circuit Unclamping circuit Principle of die clamping In general, dies ith round geometry are clamped using three clamping elements for each half, hereas dies ith square or rectangular geometry are clamped using four clamping elements for each half

15 Wedge clamp, double-acting, type for dies ith straight clamping edge Type - Clamping force axially applied to the clamping edge pplication: safe clamping of dies ith straight clamping edge for clamping of dies in injection moulding machines for clamping of dies on press bed and slide Design: Double-acting edge clamp for clamping dies on the press bed or slide or for clamping dies in injection moulding machines according to Euromap mounting grid. Unclamping stroke 200 bar The edge clamp consists of a hydraulic block cylinder connected ith a clamping bolt in a floating manner. Clamping cycle: the clamping bolt hich is inclined by 5 performs an idle stroke and simultaneously a clamping stroke. The clamping bolt is loered axially onto the clamping edge. The 5 angle of the housing has been determined so as to ensure that despite frictional engagement on the clamping edge the hydraulic pressure required for unclamping is sufficient. Clamping operation Extending and simultaneous loering/clamping Since the clamping force is ertically transmitted to the clamping point, only lo transerse forces occur. The edge clamp is aailable ith or ithout position monitoring. Please note In case of incorrect operation of the edge clamping element, the clamping bolt may fully retract into the guide housing and thus cause the upper die to fall off the slide. When using edge clamping elements on press slides or ertical presses it is recommended that multiple-circuit hydraulic supply of the clamping elements and pilot-controlled check ales are used in the clamping lines for securing hydraulic clamping. The greasing interals (high-temperature grease) should be scheduled in accordance ith the operating conditions (at least once a eek). Greasing of the clamping bolt should only be made ith the elements retracted. Special features: transerse forces are accommodated by drill bushes; high functional reliability ensured by position monitoring and automatic cycle rugged and compact design ell-proen clamping element ith high degree of safety and long serice life retracting clamping bolt ensures unrestricted die change clamping and unclamping pressures are different Position monitoring The integrated position monitoring system is coupled to the clamping bolt and signals: 1.

17 Wedge clamp, double-acting, type V for dies ith straight clamping edge Type V - Clamping force ertically applied to the clamping edge pplication: safe clamping of dies ith straight clamping edge, een in case of pressure loss for clamping of dies in injection moulding machines for clamping of dies on press bed and slide Cable length: 250 mm + plug Design: Double-acting edge clamp for clamping dies on the press bed or slide or for clamping dies in injection moulding machines. The edge clamp consists of a hydraulic block cylinder and a to-piece mechanical clamping bolt. Clamping cycle: the bolt first performs a defined idle stroke. When the inner stop is reached, the bolt is loered onto the clamping edge. The angle of the thrust pad has been determined to ensure that despite self-locking the oil pressure required for unclamping is not higher than that required for clamping. Clamping operation Extending Loering/ clamping Since the clamping force is ertically transmitted to the clamping point, no transerse forces occur. The edge clamp is aailable ith or ithout position monitoring. Please note: In case of incorrect operation of the edge clamping element, the clamping bolt may fully retract into the guide housing and thus cause the upper die falling off the slide. When using edge clamping elements on the press slide, it is recommended that multiple-circuit hydraulic supply of the clamping elements and pilot-controlled check ales are used for securing hydraulic clamping. The greasing interals (high-temperature grease) should be scheduled in accordance ith the operating conditions (at least once a eek). Greasing of the clamping bolt should only be made ith the elements being retracted. Clamping elements ith a edge clamping bolt must be protected against dirt, scale, sarf, coolant, etc. by means of a suitable coering. If penetration of such foreign matters cannot be preented, this type of element should not be used. Special features: the clamping piston does not retract in the case of pressure drop aailable in sizes of 25 kn, 50 kn and 100 kn high functional reliability ensured by position monitoring and automatic cycle rugged and compact design special ersions aailable on request ell-proen clamping element ith high degree of safety and long serice life retracting clamping bolt ensures unrestricted die change Position monitoring The integral position monitoring system is connected to the thrust pad and signals the folloing conditions: 1.

20 Safety leels for the installation of edge clamps Safety requirements are defined by safety regulations and manufacturing technology. In accordance ith up to date practice hydraulic die clamping systems are diided into 3 safety leels. 1 st safety leel: Preferably used in connection ith post-guided dies. Pressure sitches in each clamping circuit for clamping force control as machine safety. To hydraulic circuits independent of each other. Pressure sitch Clamping element Clamping circuit 1 = 50% of the clamping elements in the bed and the slide, respectiely Clamping circuit 2 = 50% of the clamping elements in the bed and the slide, respectiely Clamping circuit 1 Clamping circuit 2 Unclamping circuit If one circuit fails, the upper or loer die is still clamped ith 50% of the total clamping force. Thus, the 2 nd clamping circuit becomes a safety circuit. 2 nd safety leel: Used in connection ith dies that are not post-guided. check ale (pilot-controlled) keeps pressure in the clamping and safety circuit hen pressure drops in the remaining system. Clamping circuit 1 Clamping circuit 2 Unclamping circuit Check ale (pilot-controlled) 3 rd safety leel: Used in connection ith dies on poer presses and car body presses that are not post-guided. Clamping circuit Unclamping circuit Pressure sitch Check ale (pilot-controlled) ll clamping elements are secured by pilot-controlled check ales. In the eent of pressure drop > 20% of the operating pressure, the press is sitched off by a pressure sitch. The check ales ensure that the clamping force is maintained oer many days. For this safety leel, edge clamps ith locking bolts and ale sequence controls are used. Maximum safety by standard edge clamps

21 Extending clamp double-acting, ith mechanical lock pplications: preferably on press beds for clamping and locking dies and moing bolsters in presses Clamping: For clamping, the cylinder piston pushes the clamping leer into the clamping position. Released by the hydraulic sequence control, pressure is then applied to the clamping and locking mechanism. Once the clamping force is built up, the clamping element is self-locking. This mechanical lock preents unintentional unclamping of the die een if there is a loss of pressure. Special features: compact housing and high poer density high functional reliability ensured by position monitoring and automatic cycle self-locking by mechanical lock lo operating pressure of 100 bar easy installation Unclamping: For unclamping, the clamping and locking mechanism is hydraulically unlocked. Released by the hydraulic sequence control, pressure is applied to the cylinder piston hich pushes the clamping leer into the unclamping position. Unclamping and clamping positions are monitored by inductie proximity sitches
