1 Double General Description of WCMSH / WCMS FOR NEGATIVE ANGLE FORMING Double cam unit WCMS series is the optimum part for drilling the flat countersunk head screw holes at the door inner panel lock. UDesignation of mounting surface (View A) MFL MFR (90n125) (90n125) UDimensional designation of backup surface (View B) BFL BFR (75n125) (75n125) qtypes and Features of Double Working cam holder Mounting surface A Working cam slider Backup surface B Guide Cam Y Cam slider returns safely by positive return. YSince the cam is an aerial type, the overall design is made compact. Y If the working angle is changed, the cam shut height is constant. Y Available angle is 0.0 to.0 at increments of 0.5. The angle can be specified at increments of 0.1 from 1. to. Y Dimensions for the working cam mounting surface and the guide cam backup surface can be designated from the center line. YThe standard working force is 98 kn and the travel of the guide cam is mm. YTwo types with/without the guide cam holder are available. Select the type without holder for direct mounting on the die. Dimension can be designated from the center line in the range of 90 to 125 for the left (MFL) and the right (MFR). (Increments of 5mm) Dimension can be designated from the center line in the range of 75 to 125 for the left (BFL) and the right (BFR). (Increments of 5mm) To maintain the same relation as the mounting surface, L and R are determined when viewed from the back of the backup surface (View B). qspring specification For double cam unit WCMS series, the pressure source can be selected. Either ISO type coil spring or gas spring (aller) can be selected.

3 Double General Description of WCMSH / WCMS FOR NEGATIVE ANGLE FORMING qstructure and Assembly/Disassembly of WCMSH qstructure and Assembly/Disassembly of WCMS r Note) Assembly and disassembly procedures are the same as WCMSH on the left page. e UDisassembly method of a w 1) Remove hexagon socket head bolt ( ) and remove stopper plate (@0). 2) Pull and remove cam slider(e) from cam holder B(r) to the rea. Guide cam (w) can be removed upward by removing spring stopper (!9) and cam upper plate (t). Cam Upper plate Guide Cam Side Plate t Stopper!9 Cam Guide Spring Stopper Spring Stopper Block Wear Plate UAssembly method of WCMSH 1) Assemble components in the reverse order of disassembly. Y Make sure that there is no foreign matter on the sliding area and assemble components. Y The clearance between the cam slider and the cam holder is controlled. Match the stamped serial number on the holder and slider before assembly. Y When cam is disassembled and then reassembled, please do not forget to assemble all bolts provided. Y The guide cam mounting surface (mounting surface of wear plate) is machined for mounting the stopper and the spring stopper block. Y Side plate A wall surface for forward/backward movement of the guide cam is provided. Fixing and sliding is controlled with the Cam upper plate
