Abstract
The utility model provides a kind of heat exchanger tube head cutter.The cutter is provided with blade screw position on cutter hub, blade screw position is provided with blade fastening screw, power connections and blade are connected by blade fastening screw with cutter hub, and the other end of cutter hub is equipped with bearing and gasket, and is fastened on cutter hub by bearing fixing bolt.The cutter structure, which simply only needs a heat exchanger to make the common electric tube expander source of being used as power, can be operated, and tool bit part is equipped with bearing, and not only stability is good, and more can be reduced the damage that heat pipe inner wall is exchanged when rotation.The cutting speed of the cutter is fast, can greatly improve working efficiency.
Description
Technical field
The utility model relates to arrive cutter and cutter field, it is related specifically to a kind of heat exchanger tube head cutter.
Background technique
In current most of chemical industry equipment manufacturing enterprises, when manufacturing tube-sheet heat exchanger, need exchanger tubes and tubesheets
One welded, welding after the completion of weld tube sheet other end again, in the welding process sometimes due to heat exchanger tube length exist
There is deviation, when guaranteeing that one extension elongation of tube sheet is consistent, tube head stretches out before will result in the other end Tube-sheet Welding of heat exchanger tube
It is different in size, seriously affected Tube-sheet Welding operation and beautiful, need that the tube head of stretching is polished to length with angle grinder it is consistent,
This mode of operation, which exists, to be had disadvantages that: 1, since the tube head that the limitation of angle grinder structure polish all has certain angle；
2, polishing, which will appear many burrs, influences welding quality；3, very big noise and iron filings dust can be generated when being polished with grinding wheel；4,
Grinding wheel loss is larger, and when damage can also hurt sb.'s feelings, and operates time-consuming and laborious, increases processing cost.Therefore a kind of convenience, peace are needed
Entirely, cheaply, efficiently tool come substitute complete tube head cutting work.
Summary of the invention
The purpose of this utility model is to provide a kind of to replace the heat exchanger tube head of polishing to cut using alloy blade cutting
Cut device.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of heat exchanger tube head cutter, comprising: dynamic link part, bearing fixing bolt, gasket, bearing, cutter hub, blade
Fixing screws and blade, the cutter are provided with blade screw position on cutter hub, and blade screw position is provided with the fixed spiral shell of blade
Nail, power connections and blade are connected by blade fastening screw with cutter hub, and the other end of cutter hub is equipped with bearing and gasket, and
It is fastened on cutter hub by bearing fixing bolt, the power connections of cutter hub are connected with external power source.
Compared with prior art, the utility model good effect are as follows:
1, the cutter structure, which simply only needs a heat exchanger to make the common electric tube expander source of being used as power, can be operated；
2, the tool bit part of the cutter is equipped with bearing not only stability is good, and while more can be reduced rotation exchanges heat pipe inner wall
Damage；
3, the blade on the cutter is fixed by screws on knife rest, and the replacement of blade is very operated quickly and conveniently；
4, the cutting speed of the cutter is fast, can greatly improve working efficiency；
5, the cutter does not have burr and dust that the later period is facilitated to weld after cutting on heat exchanger tube head；
6, the smooth tube head that the cutter is cut is not in tilt angle.
Detailed description of the invention
Fig. 1, heat exchanger tube head cutter schematic cross-sectional view.
In figure；1, power connections, 2, blade cut sword, 3, blade screw position, 4, tube sheet, 5, heat exchanger tube, 6, bearing it is solid
Determine bolt, 7, gasket, 8, bearing, 9, cutter hub, 10, blade fastening screw, 11, blade.
Specific embodiment
Clear, complete description further is carried out to the technical solution of the utility model with reference to the accompanying drawing.
Referring to attached drawing 1, first in the blade screw position 3 in cutter hub 9, with blade fastening screw 10, by blade 11 and move
Power connector 1 is attached fixation, gasket 7 and bearing 8 is mounted in the other end of cutter hub 9, and carried out tightly with bearing fixing bolt 6
Gu.After the insertion of cutter hub 9 is mounted in heat exchanger tube 5 on tube sheet 4, power connections 1 are made to drive cutter by external power source
Rotation, the blade cut sword 2 allowed on blade 11, which exchanges heat pipe 5 and stretches out extra part, to be cut, with alloy blade cutting come
Instead of polishing.Long cutter hub 9 set by cutter is used to prevent the swing of blade 11, and the bearing 8 of 9 end of cutter hub setting is for subtracting
Exchange 5 inner wall of heat pipe damage less after cutter hub 9 is inserted into heat exchanger tube 5, allows blade cut sword 2 on blade 11 by the rotation of cutter hub 9
Extra tube head is cut on exchange heat pipe 5, and the tube head length to guarantee heat exchanger tube 5 is consistent.
