Abstract
Theinvention provides a chip-free cutting knife tooling for an aluminum flat pipe with large hole pitch. The chip-free cutting knife tooling comprises a knife rest, wherein one side of the lower end of the knife rest is provided with a press plate groove; a press plate is arranged in the press plate groove; press heads are arranged at the lower ends of the press plate and the knife rest; the middle part of the lower side of the press plate is provided with a cutting knife groove; the press plate at both sides of the cutting knife groove is provided with deburring knife grooves; a cutting knife is arranged in the cutting knife groove, and is arranged on the press plate through a cutting knife fixing bolt; a deburring knife is arranged in each deburring knife groove, and is arranged on the press plate through a deburring knife rest; the upper end of each deburring knife rest is connected with a deburring knife adjusting handle. The chip-free cutting knife tooling has the advantages that by arranging the deburring knives at both sides of a knife blade, after the pipe wall is cut by the cutting knife, the aluminum burrs, higher than the pipe wall, of the outwards folded aluminum chips are directly scraped by the following deburring knives in the working state; the action forces of the cutting knife and deburring knives on the surface of the pipe wall are parallel with the pipe wall, the collapsing of the pipe wall is avoided, and the hole height of the cut cross section is better than the two existing chip-free cutting types.
Description
Technical field
The present invention relates to heat exchanger aluminium flat conduit process equipment, specially a kind of big hole pitch aluminium flat conduit chipless cutting off tool work
Dress.
Background technology
At present, existing automobile and business air conditioner heat exchanger aluminium flat conduit, wall thickness is less than 0.4mm, and pitch of holes is less than 1.5mm,
After cut-out, do not allow incision to have any aluminium skimmings, therefore draw to have no progeny using upper down tube face and break, for ensureing production efficiency, cutting knife is past
Multiple cutting-up.When pitch of holes is more than 1mm, existing hobboing cutter, because during cut-out, flat tube surface is streaked in blade rotation, thus in cut-out
When, cutting knife flat tube surface forms inward pressure, and blade gos deep into the aluminum burr that tube wall squeezed out can together descend in pressure pipe, cause
After making cut-out, incision hole high convergency, and then reduce the actual internal area of original design heat transferring medium.
And the piece knife of crescent shape, although not rotating, streaks flat tube surface, cutting knife power of being formed in cut-out switchs to parallel
In flat tube surface, incision hole height also obtain maximum guarantee, but in cutting-up, with the change of stress, incision is deep because of blade
Enter the aluminum burr that tube wall squeezed out to turn up, will eminence tube wall, so will result in otch thickness become big it is impossible to insertion afflux
Pipe, does not solve this problem, is loaded on piece knife both sides using ball or roller at present, after cutting knife streaks, ball or roller roll and turn up
Aluminum burr, and in roller compaction process, aluminium flat conduit equally inwardly has certain collapsing, and that is, hole height diminishes, but because dynamics diminishes, cuts
Oral pore is higher than hobboing cutter otch.
And for pitch of holes in the aluminium flat conduit of 1～1.5mm, adopt in the industry piece knife at present, because the change of span is big, cut bearing
When knife cuts off or removes the grinding pressure of thorn device, wall thickness is too thin, and holding capacity is not enough, causes otch to subside seriously, tube wall is in incision
Present wavy, have the just height that muscle supports, do not have is just low, but meets the requirements in front, after pitch of holes is more than 1.5mm, otch
Subside serious, be unable to reach technical requirements, at present, thus can only produce big using the cut-out of high-speed rotation saw blade in the industry
Amount aluminium skimmings, and need also exist for removing otch burr, in pipe aluminium skimmings remove very difficult, and cannot thorough cleaning clean, this
Just to supporting after parts, aluminium skimmings will enter in whole machine heat-exchange system sample, and drawback is fairly obvious.
Content of the invention
Technical problem solved by the invention is to provide a kind of big hole pitch aluminium flat conduit chipless cutting off tool frock, to solve
The certainly problem in above-mentioned background technology.
Technical problem solved by the invention employs the following technical solutions to realize: a kind of big hole pitch aluminium flat conduit chipless is cut
Breaking has frock, comprising: knife rest, described knife rest lower end side is provided with pressing plate groove, is provided with pressing plate, pressing plate and knife rest in pressing plate groove
Lower end is provided with pressure head, and under pressing plate, middle side part is provided with cutting knife groove, and the pressing plate of cutting knife groove both sides is provided with deburring cutter groove, described cutting knife
Cutting knife is installed in groove, cutting knife is arranged on pressing plate by cutting knife fixing bolt, in deburring cutter groove, burring knife is installed, goes
Deburring cutter is arranged on pressing plate by burring knife knife rest, and burring knife knife rest upper end is connected with burring knife adjusting handle, unhairing
Bayonet adjusting handle is arranged on knife rest upper end, is threaded connection between burring knife adjusting handle and knife rest.
Angle between the outside of described burring knife and pressing plate is 30-80 °, the angle between the interior side guide of burring knife
Spend for 90 °, the angle between cutting knife both sides and pressing plate is 30-80 °.
Described pressing plate is arranged in pressing plate groove by pressing plate fixing bolt, and the size of pressing plate is consistent with pressing plate groove.
Compared with disclosed technology, there is advantages below in the present invention: the present invention is assembled with burring knife in blade both sides,
During the cutting-up of left and right, during cutter advance cutting-up, before direction of advance, go bayonet not work, after go bayonet to work, such cutting knife scratches
Tube wall, the aluminum burr of eminence tube wall is subsequently directly struck off by the aluminium skimmings turned up by the bayonet that goes immediately following working condition, because of cutting knife and
Burring knife tube wall surface active force all with tube walls parallel, just do not produce tube wall and collapse, otch section hole height is superior to existing
There are two kinds of chipless cut-out modes.
