Abstract

The utility model relates to a auxiliary fixtures of processing heat exchanger specifically is grooving ware in release of stress groove on processing heat exchanger tube sheet. The problem of the last release of stress groove of heat exchanger tube sheet lacks suitable machining tool or frock is solved. This grooving ware comprises grooving ware body, tool section and fastening bolt, grooving ware body comprises the tool section fixed part by the transition portion at clamping part, middle part and lower part at top, and the tool section fixed part passes through the hollow cylinder of bottom plate shutoff for the bottom, and it has tool section fixing hole to open on hollow cylinder's the face of cylinder, and tool section fixing hole's axis intersects vertically with hollow cylinder's axis, and it has the screw to open on hollow cylinder's the bottom plate, the both ends on a long limit of tool section are equipped with the cutting part symmetrically, the tool section wear in the tool section fixing hole and two cutting parts that make the tool section hollow cylinder outside, be hollow cylinder's axis symmetry and perpendicular downward, fastening bolt twists in the screw and makes its tight tool section in tip top. It the ideal instrument of heat exchanger processing.

Description

The Slot digger of the stress relief grooves on processing heat exchanger tube sheet
Technical field
The utility model relates to the auxiliary mould of the processing heat exchanger particularly tube sheet of falling-film heat exchanger, is specially the Slot digger of the stress relief grooves on processing heat exchanger tube sheet.
Background technology
In the process of heat exchanger tube sheet, need machining stress release groove around the pore on tube sheet.At present, owing to lacking suitable machining tool or frock, the process of stress relief grooves is more complicated, and working (machining) efficiency is lower, and the crudy of stress relief grooves is also difficult to ensure.
Summary of the invention
The stress relief grooves that the utility model solves on heat exchanger tube sheet lacks suitable machining tool or the problem of frock, provides a kind of Slot digger of the stress relief grooves processed on heat exchanger tube sheet.
The utility model is achieved by the following technical solution: the Slot digger of the stress relief grooves on processing heat exchanger tube sheet, is made up of Slot digger body, tool section and fastening bolt; Slot digger body being formed by the tool section fixed part of the transition part at clamping part, middle part and bottom by top, tool section fixed part is the hollow cylinder of bottom by base plate shutoff, the face of cylinder of hollow cylinder has tool section fixed via, the axis of tool section fixed via and the intersect vertical axis of hollow cylinder, the base plate of hollow cylinder has screw; The two ends on one long limit of described tool section are provided with blade symmetrically, tool section to be through in tool section fixed via and make that two blades of tool section are external at hollow cylinder, axisymmetrical in hollow cylinder and vertically downward; Described fastening bolt to be twisted in screw and is made its end hold out against tool section.This Slot digger is installed on radial drilling machine as accurate drill bit when using, Slot digger bodies top be held on radial drilling machine by clamping part, the tool section fixed part of hollow cylinder shape is made to stretch into pore on heat exchanger tube sheet, Slot digger rotates under drilling machine drives, and two blades of tool section will dig out stress relief grooves.By regulating the parameter of drilling machine and tool section, reach the grooving degree of depth of art work sheet requirement and the object of size.
Slot digger structural design described in the utility model is simple, novel, unique, practical, not only working (machining) efficiency can be improved, saving human and material resources, and ensure that the quality of dug stress relief grooves, is the ideal tools of the special falling-film heat exchanger processing of heat exchanger.
