Abstract
The present invention provides a kind of big pitch of holes aluminium flat conduit chipless cutting off tool frock, including：Knife rest, knife rest lower end side is provided with pressing plate groove, pressing plate is installed, pressing plate and knife rest lower end are provided with pressure head, and middle side part is provided with cutting knife groove under pressing plate in pressing plate groove, the pressing plate of cutting knife groove both sides is provided with deburring cutter groove, cutting knife is installed, cutting knife is arranged on pressing plate by cutting knife fixing bolt, and burring knife is provided with deburring cutter groove in the cutting knife groove, burring knife is arranged on pressing plate by burring knife knife rest, and burring knife knife rest upper end is connected with burring knife adjusting handle.The present invention is assembled with burring knife in blade both sides, so cutting knife scratches tube wall, the aluminium skimmings turned up then are gone bayonet directly to strike off the aluminium burr of eminence tube wall immediately following working condition, because cutting knife and burring knife tube wall surface active force all with tube walls parallel, tube wall collapse is not just produced, and otch section hole height is superior to existing two kinds of chipless cut-out mode.
Description
Technical field
The present invention relates to heat exchanger aluminium flat conduit process equipment, specially a kind of big pitch of holes 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 are less than 0.4mm, and pitch of holes is less than 1.5mm,
After cut-out, do not allow incision there are any aluminium skimmings, therefore use upper down tube face stroke to have no progeny and break, it is past for guarantee production efficiency, cutting knife
Multiple cutting-up.When pitch of holes is more than 1mm, existing hobboing cutter, during because of cut-out blade rotation streak flat tube surface, thus cutting off
When, cutting knife flat tube surface forms inward pressure, and blade, which gos deep into the aluminium burr that tube wall is squeezed out, together to be descended in pressure pipe, causes
After making cut-out, incision hole high convergency, and then reduce the actual internal area of former design heat transferring medium.
And the piece knife of crescent shape, although not rotating, flat tube surface is streaked, the power that cutting knife is formed in cut-out switchs to parallel
In flat tube surface, incision hole height also obtain maximum guarantee, but in cutting-up, as the change of stress, incision are deep because of blade
Enter the aluminium burr that tube wall is squeezed out to turn up, will eminence tube wall, so will result in otch thickness and become big, afflux can not be inserted
Pipe, this problem is not solved, piece knife both sides are loaded on using ball or roller at present, after cutting knife streaks, ball or roller are rolled and turned up
Aluminium burr, and in roller compaction process, aluminium flat conduit equally inwardly has certain collapse, i.e. hole height diminishes, but because dynamics diminishes, cuts
Oral pore height is higher than hobboing cutter otch.
And use piece knife in the industry at present for pitch of holes, because the change of span is big, bearing to cut in 1~1.5mm aluminium flat conduit
When knife cuts off or removes the grinding pressure of thorn device, wall thickness is too thin, endurance deficiency, causes otch to collapse seriously, tube wall is in incision
Wavy, to have muscle to support just height is presented, no is just low, but meets the requirements in front, after pitch of holes is more than 1.5mm, otch
Collapse seriously, be unable to reach technical requirements, at present, high speed rotating saw blade can only be used to cut off in the industry, thus produced big
Measure aluminium skimmings, and need also exist for removing otch burr, aluminium skimmings remove very difficult in pipe, and can not thorough cleaning it is clean, this
Sample just to support parts after, aluminium skimmings will enter complete machine heat-exchange system in, drawback is fairly obvious.
The content of the invention
Technical problem solved by the invention is to provide a kind of big pitch of holes aluminium flat conduit chipless cutting off tool frock, with solution
The problem of in certainly above-mentioned background technology.
Technical problem solved by the invention is realized using following technical scheme：A kind of big pitch of holes aluminium flat conduit chipless is cut
Breaking has frock, including：Knife rest, knife rest lower end side are provided with pressing plate groove, pressing plate, pressing plate and knife rest are provided with pressing plate groove
Lower end is provided with pressure head, and middle side part is provided with cutting knife groove under pressing plate, and the pressing plate of cutting knife groove both sides is provided with deburring cutter groove, the cutting knife
Cutting knife is installed, cutting knife is arranged on pressing plate by cutting knife fixing bolt, is provided with burring knife in deburring cutter groove, goes in groove
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 connected through a screw thread between burring knife adjusting handle and knife rest.
Angle between the outside of the 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 °.
The 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, go bayonet not work before direction of advance, after go bayonet to work, such cutting knife is scratched
Tube wall, the aluminium skimmings turned up then are gone bayonet directly to strike off the aluminium burr of eminence tube wall 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 collapse, otch section hole height is superior to existing
There are two kinds of chipless cut-out modes.
