Description
(1) technical field
The utility model relates to a kind of machine tool, what be specifically related to is that a kind of heat exchanger tube head and weld seam are cut device with drawing.
(2) background technology
The tubular heat exchanger series products phenomenons such as tube head spalling, commissure defective occur and reaches useful life period changing heat exchanger tube through regular meeting.To this, before the utility model occurred, the main way that can take was cut and turning the tubulation that tube head spalling or breakage occur nothing more than, destroys heat exchanger tube even tube sheet.Though be to have taken off this tubulation like this, but caused great waste inevitably.Time-consuming in addition, effort, the operation complexity, product cost also raises.
(3) summary of the invention
The purpose of this utility model just provides a kind of heat exchanger tube head and the weld seam that operation is simple, efficient and product cost is lower and cuts device with drawing.
The technical scheme that adopts is:
A kind of heat exchanger tube head and weld seam are cut device with drawing, comprise drive unit, reducing gear, guiding mechanism, retaining mechanism, cutting mechanism, drive unit comprises motor, shaft coupling, motor mounting has shaft coupling, reducing gear comprises the deceleration body, the reductor power shaft, speed reducer output shaft, the deceleration body is equipped with the reductor power shaft, speed reducer output shaft, drive unit is connected with reducing gear by the mode that shaft coupling and reductor power shaft join, it is characterized in that: cutting mechanism is installed on the speed reducer output shaft, in the deceleration body guiding mechanism is installed, retaining mechanism is connected with guiding mechanism by the mode among the axle sleeve of the pull bar insertion guiding mechanism of retaining mechanism.
Above-mentioned guiding mechanism comprises axle sleeve, adjusts cover, adjusts in the cover axle sleeve is installed;
Above-mentioned cutting mechanism comprises knife rest, cutting knife, and cutting knife is installed on the knife rest;
Above-mentioned retaining mechanism comprises handle, pull bar, spacer, lock sleeve, locking nut, one end of pull bar is equipped with handle, near on the pull bar outer wall at handle place spacer is installed, on the pull bar outer wall in the knife rest outside lock sleeve is installed, pull bar stretches out the outer end of axle sleeve locking nut is installed.
When using this instrument, in the end insertion heat exchanger tube with lock sleeve, pull handle, lock sleeve is expanded in the circumferencial direction distortion, play the locking effect, rotate then and adjust cover, reducing gear and cutting mechanism are moved axially along axle sleeve, realize the feed and the withdrawing of knife rest.
Advantage of the present utility model is: device is dexterous, and is simple to operate, easy to carry; Save consumption reduction; Method than before can be raised labour productivity 10～12 times, has remarkable economic efficiency.
