Triple phase cutting hole machining tool and machining process for copper cooling wall

Abstract

The invention discloses a triple phase cutting hole machining tool and a triple phase cutting hole machining process for a copper cooling wall. According to the machining tool and the machining process, a drill bit body is provided with a guide groove; the drill bit body can realize direction guidance in a deep hole machining process by virtue of the guide groove; meanwhile, when the machining tool is used for machining a region of which the hole position is relatively deep, the drill bit body is additionally provided with a drill bit extension bar; the outer wall of the drill bit extension rod is provided with a plurality of guide bumps; by the structure setting, the drill bit body adopts a shape design that a spiral guide groove is provided, the guidance effect of the spiral guide groovecan reduce the vibration, at the inlet, of the drill bit body, can improve the guidance capability of the drill bit body, and can reduce hole deflection; and when the machining tool is used for machining a relatively deep hole, a plurality of guide bumps on the outer wall of the drill bit extension bar can effectively realize extension guidance so as to further guarantee the stability in machining of a center hole.

Description

technical field [0001] The invention relates to the technical field of processing three-link phase cutting holes of copper cooling walls, and specifically discloses a cutting tool and a processing technology for three-link phase cutting holes of copper cooling walls. Background technique [0002] At present, in the field of iron and steel smelting technology, in order to achieve a better physical cooling effect, a cooling device is generally installed in the blast furnace, and the copper stave with three consecutive rings of cut holes is widely used in the industry as a component with high heat dissipation efficiency. Its specific structure is as figure 1 As shown, the copper stave three-link cut hole is composed of three connected holes. [0003] When the existing common BTA internal chip removal deep hole drill is used to process the three-link phase cutting hole of the copper stave, when the middle hole is processed, the left and right sides of the tool have no support a...
