Abstract
The utility model discloses a pipe head reshaping cutter, which comprises a cutter rest and an alloy blade. The cutter rest comprises a guide rod, a cutter disc and a transmission rod. The cutter disc is provided with a cutter groove along the axis direction, the cutter groove is provided with a bolt hole, the alloy blade is fixed in the cutter groove of cutter disc through a jack screw, and the guide rod and the transmission rod are both provided with bolt holes for installation and positioning of the pipe head reshaping cutter. During work, the guide rod is extended into a pipe fitting, the transmission rod is connected with a driving device which drives the cutter disc and the alloy blade to perform rotary movement on a work face, and a surface to be machined is processed through the alloy blade. Compared with the prior art, the pipe head reshaping cutter has the advantages of being simple in structure, convenient to operate and good in cleaning effect.
Description
Technical field
The utility model relates to a kind of cutter, relates in particular to a kind of tube head shaping cutter.
Background technology
In the machinery production process, many times all to use pipe fitting; Because required pipe fitting length is different; When concrete the use, often to cut, cause tube head to leave the situation that burr causes appearance poor even influence back operation to carry out through regular meeting in the time of cutting pipe fitting.In the production process of heat exchanger, the situation that the defective needs of welding quality between heat exchanger tube and the tube sheet weld again also often appears, when welding again, at first to clean out original welding slag.Usually adopt the method for grinder buffing to overcome the above problems under the prior art situation, and the method for grinder buffing can't guarantee crudy usually, easily tube head caused damage or not thorough, influence follow-up use the tube head cleaning.
The utility model content
The purpose of the utility model is to provide a kind of tube head shaping cutter, to solve the problem that exists in the present tube head scale removal process, has advantage simple in structure, easy to operate, that cleaning effect is good.
The purpose of the utility model is to realize through following technical scheme:
A kind of tube head shaping cutter comprises knife rest, alloy blade, and said knife rest comprises the guide post of front end, middle cutterhead, the drive link of rear end, and said cutterhead is in axial direction offered some cutter grooves, is placed with alloy blade in the said cutter groove.
Have bolt hole on the said cutter groove, said alloy blade is fixed on the cutterhead through jackscrew.
Be provided with said tube head shaping cutter installing and locating on said guide post, the drive link and use bolt hole.
Be with positioning sleeve on the said guide post.
The beneficial effect of the utility model is: through guide post being set, when drive link is worked, guide post being stretched into pipe fitting inside, drive link connects drive unit, makes knife rest and alloy blade do gyration at working surface, through alloy blade tube head is handled.The positioning sleeve wall thickness can be selected according to institute's processing pipe fitting internal diameter size, has strengthened the versatility of tube head shaping cutter, makes things convenient for blade to dismantle reconditioning with the jackscrew fixed blade.The contrast prior art, this tube head shaping cutter has advantage simple in structure, easy to operate, good to the tube head cleaning effect.

The specific embodiment
In Fig. 1～5 illustrated embodiments; The described a kind of tube head shaping cutter of the utility model; Comprise knife rest 1, alloy blade 2, knife rest comprises guide post 11, cutterhead 12, drive link 13, and cutterhead is along having some cutter grooves 14 on the axis direction; Have bolt hole 15 on the cutter groove, alloy blade is fixed on the cutterhead 12 through jackscrew.Guide post 11, drive link 13 are provided with that said tube head shaping cutter is installed, bolt hole use in the location, are respectively applied for guide post 11 installing and locating and overlap 4 and be connected transmission device with drive link 13, and the size of positioning sleeve 4 is selected according to the internal diameter size of heat exchanger tube.
During work; At guide post 11 outside socket positioning sleeves 4, stretch into heat exchanger tube 5 inside then in the lump, make alloy blade 2 be positioned at the solder side of tube sheet 6 and heat exchanger tube 5; Through connect drive unit in drive link 13 ends; The 1 whole rotation of drive device drives knife rest makes alloy blade 2 in the solder side rotation of tube sheet 6 with heat exchanger tube 5, thereby reaches the purpose that welding slag is cleaned out.
