Description
Technical field
This utility model belongs to technical field of chemical equipment manufacturing, the instrument of a kind of tube sheet end-grain cutting pipe cutting head.
Background technology
In modern society, chemical products have been applied to the every aspect of the daily productive life of people.The quality of chemical products and yield, depend greatly on chemical industry equipment the most qualified, meets high temperature that chemical machinery itself is frequently encountered, high pressure, fine vacuum, ultralow pressure, the particular/special requirement such as inflammable, explosive.
Heat exchanger is as an important branch of chemical industry equipment, and its manufacturing process has a lot of particular criteria, therefore can run into a lot of difficult point in the course of processing.Tube head cutting is a link the most important in heat exchanger processing, and tube head extension elongation directly influences welding difficulty or ease and the welding quality of tube head.In tube head cutting process, the depth of parallelism of facet and tube sheet often has influence on production efficiency and product quality, careless slightly heat exchanger tube will be made to scrap, and What is more can cause damaging tube sheet, directly influences the safety in production of heat exchanger.The shortcomings such as during traditional tube head cutting operation, the facet depth of parallelism requires higher, time and effort consuming, and production efficiency is low, tube head cut quality difference, become the difficult point of making.
Summary of the invention
This utility model is in order to solve the problems referred to above, it is provided that the instrument of a kind of tube sheet end-grain cutting pipe cutting head, and this utility model uses plane fixed emery wheel machine mode, simple to operate, cutting area is big, and cut quality is excellent, save production cost, reduce manpower consumption, it is ensured that the quality of equipment making.
This utility model adopts the following technical scheme that realization: the instrument of a kind of tube sheet end-grain cutting pipe cutting head, including left support frame, right support frame and litter；The end, two ends of left support frame and right support frame is designed with adjusting bolt, being additionally provided with chute in left support frame and right support frame, the both ends of litter lay respectively in the chute in left support frame and right support frame, and litter is provided with roller, it is fixed with larynx hoop on roller, larynx hoop is fixed with abrasive machine.
During use, left support frame and right support frame are positioned on the tube sheet of processing tube head, by positive and negative adjustment bolt, bracing frame is fixed on tube sheet, and regulate the height of adjustment bolt to ensure the length of tube head, on the other hand parallel being fixed on tube sheet of bracing frame is also made, abrasive machine is firmly fixed on litter by larynx hoop, the side-to-side movement that abrasive machine can be realized on litter by the roller on larynx hoop, moving through litter chute in bracing frame before and after abrasive machine to realize, such abrasive machine just can carry out tube head cutting operation in a plane.
The adjustment number of bolts that the instrument of above-mentioned a kind of tube sheet end-grain cutting pipe cutting head, left support frame and each end of right support frame are arranged is two, and one is positive justification bolt, and one adjusts bolt for counter.
The instrument of above-mentioned a kind of tube sheet end-grain cutting pipe cutting head, the end, one end of left support frame and right support frame is additionally provided with slide block, and the adjustment bolt of this end is arranged on slide block.By adjusting two slide blocks of bracing frame, determine the position of fixing point, to adapt to different size of tube sheet.
This utility model has obvious advance compared with background technology, be for tube sheet end cut tube head during drawback and design, secure the cutting planes of abrasive machine, it is possible to along with the difference of tube sheet size, fixed position is changed by the slip of slide block, being suitable for producing, abrasive machine is fixed, and abrasive machine can be with omnibearing activity in fixed pan, cutting area is big, save workman's muscle power, save production cost, it is ensured that the quality of the cutting of tube head.This tool design is advanced, simple in construction, arranges rationally, is the instrument of very good tube sheet end-grain cutting pipe cutting head.
