Manufacturing method of oblique sharp angle gardening scissor blade, rough, and product thereof including steps of rough forming, blade back grinding, blade surface grinding, blade grinding, and finished product installation
The present invention relates to a manufacturing method of oblique sharp angle gardening scissor blade, rough, and product thereof. The manufacturing method sequentially includes the following steps: rough forming, blade back grinding, blade surface grinding, blade grinding, and finished product installation. In the present invention, a bending section is formed at a blade tip of a rough. The bending section provides enough grinding allowance when grinding the blade, in order to complete grinding by grinding tools in one time, without performing multiple steps of grinding. Thus an oblique sharp angle is formed at a front end of the blade tip of a finished product, so as to effectively reduce the size of the blade tip portion for cutting a tiny object.本發明係關於一種斜尖角園藝剪刀刃之製造方法、粗胚及其製品,其係有下列步驟,依序包括粗胚成形、刀背研磨、刀面研磨、刀刃研磨及成品安裝;本發明係於一粗胚之刀尖成形有一彎折段,此彎折段提供刀刃研磨時有足夠的研磨裕度,而能夠以研磨工具一次性地完成研磨,無需進行多重道次的研磨,並於一成品的刀尖前端形成一斜尖角,可以有效縮小刀尖部位的尺寸,以利進行細小物品的剪切。S1‧‧‧粗胚成形S2‧‧‧刀背研磨S3‧‧‧刀面研磨S4‧‧‧刀刃研磨
