一般工厂所用的淬火提钩是一个直弯头的,提取工件很不方便.后来,我们把它改成如附图所示的形式,在淬火加热和冷却时用来提取一般小型的用铁丝绑扎的零件方便得很.假如提取一般淬火加热用的卡具,可以将淬火提钩的铁棍加粗,并概据实际需要决定提钩的长短。 Quenching hook used in the general factory is a straight elbow, the extraction of the workpiece is very inconvenient. Later, we put it into the form as shown in the drawings, quenching heating and cooling used to extract the general small wire banding Of the parts is very convenient.If the general extraction of quenching with the fixture, the hook can be hardened to mention iron bar thicker, and according to the actual needs of the decision to mention the length of the hook.
