Zusammenfassung: | To provide a wiper that achieves high durability with sufficient strength of adhesion between a lip part and a fitting part, and causes reduced looseness of a fastening bolt during sliding on a cleaning target surface at the tip of the lip part and reduced distortion and deflection of a wiper due to excessive fastening of the fastening bolt.SOLUTION: A wiper 1 that is attached to a machine tool to wipe a cleaning target surface comprises: a belt-shaped installation part 10 having a reinforcement plate 10a made of a rigid material and a back part 10b made of an elastic material provided on the reinforcement plate 10a; and a lip part 11 made of an elastic material, installed on a side surface in a short direction of the installation part 10, and has a sliding part 11a that slides in contact with the cleaning target surface. A thickness of the back part 10b is more than 0 mm and 0.5 mm or less. The reinforcement plate 10a has a Rockwell hardness HRB of less than 65 and a Vickers hardness HV of less than 115.SELECTED DRAWING: Figure 1B
【課題】リップ部と取付部との接着強度が十分で高い耐久性を実現するとともに、リップ部の先端の被清掃面上の摺動中における締付ボルトのゆるみの発生、及び締付ボルトの過剰な締付によるワイパーの歪み及びたわみの発生が抑制されたワイパーを提供する。【解決手段】工作機械に取り付けられて被清掃面を拭き取るワイパー1であって、剛性材料からなる補強板10aと補強板10aに積層して設けられた弾性材料からなる背部10bとを有する、帯状の取付部10と、弾性材料からなり、取付部10の短手方向の側面に取り付けられ、被清掃面に接して摺動する摺動部11aを有するリップ部11と、を備え、背部10bの厚さが0mmより大きく0.5mm以下であり、補強板10aは、ロックウェル硬さHRBが65未満及びビッカース硬さHVが115未満である構成とする。【選択図】図1B |
