51φ6H72ーM8 depth 20renateRiAir cylinder direction alterationTLC（0）Ball plunger installationBPC（1,200）Process a bolt hole on switch sensor, and install a ball plunger on the bottom of the body.Features●Compact design enables usage in limited working space. Punching performance will not be affected by shortened select bar.●High-rigid body is durable, and the design of small opening can prevent malfunction caused by entrance of scrap.●For the select ring ② with stop flat alteration, high-precision location can be achieved when combined with special shaped punches.●A ball plunger is mounted on the bottom of air cylinder ⑥ after alteration BPC, in order to prevent select bar ③ from moving when the air pressure is low.●Change retainers can also be used for side·top punchingSteps of operation1.Press the punch into the retainer.2.Tighten the plunger on the side of select ring. Note: Over-tightened plunger may cause deformation of punch.3.Put springs into the 2 spring holes, and press the select ring mounted with punch into the retainer. Lay grease or lube on the punch or the punch mounting part of retainer. 4.Mount the select bar. Select bar works when pressure air is loaded. Lay grease or lube on the select bar and the side of select ring.5.Confirm if the select bar is higher than retainer surface,then mount the backing plate ④. Confirm if the screw hole or dowel hole for mounting is in right position.6.Connect the air tube, and confirm the working performance of retainer before mounting it into the mold.Notes for the above items●The set stroke of change retainer is 8mm. ●Please select the air tube of external diameter 6mm, internal diameter 4mm.●Prevent lowered air pressure when working, and 0.5〜1.0MPa（5.1〜10.2kgf/cm2） air pressure is recommended. For alteration, a ball plunger is mounted, and the position of punch（at the end of stroke）is retained after punching.●Screw hole alteration of φ5.8 is applied on dowel holes of retainer body. Adjust the mounting position, and combined using with the mold. ●Mount the screw plugs (accessory) to prevent slotted pins falling.●Alter the head thickness of punch through alteration RC. In standard tolerance, the higher the projecting part of punch to retainer, the higher the probability of malfunction is. （Punches with centre hole can be used directly.）●Change retainers can’t be used for punching in molds of small clearance.Code No.（TLC,BPC…etc）GCAR10 −TLC270ーBPCAdd.Code（@/P）Alter the air cylinder direction.StandardTLC270Spec.TLC90TLC180Add.Code（@/P）JNC（ー200）Cancel the joint from air cylinder.Joint cancellingJoint alterationJLC（0）Dowel hole precision processingNSC（1,500）Process the dowel hole to φ6H7.The dimension tolerance between punch and dowel holes K2 is ±0.01.Dimension tolerance between dowel holes is ±0.01.Product unit price＋Addition unit price.Price discount is also available for addition.17Spec.
