Description
Technical field
The present invention relates to lathe tool technical field, and in particular to a kind of car for being used to process ultra-thin breadth polytetrafluoroethylene film
Cutting knife tool.
Background technology
Polytetrafluoroethylene (PTFE) (PTFE) is commonly called as " King ", and polytetrafluoroethylene (PTFE) has especially advantageous spy among various plastics
Property.Such as：Its heat resistance, lower temperature resistance, resistance to chemical reagents, electric insulation and high frequency characteristics etc. are especially advantageous, but also have
Unique non-adhesive, sealing, low frictional properties and good ageing resistance.If added in polytetrafluoroethylene (PTFE) Product processing
The fillers such as carbon black, glass, carbon fiber, ceramic powder, molybdenum disulfide, its product more improve polytetrafluoroethylene (PTFE) compressive strength,
It is more resistant, increased thermal conductivity, many advantages, such as reducing thermal expansion, with more creep resistant, resistant to chemical etching, low-friction coefficient, low
The performance such as abrasion and rigid good toughness, weatherability.Due to these excellent characteristics, therefore polytetrafluoroethylene (PTFE) product is not only employed
In chemical industry, electric, electronics industry and mechanical industry, and it is also extensively used for from Aeronautics and Astronautics, defense industry to doctor
Treat, the every field of household supplies.
The manufacture of polytetrafluoroethylene film generally has two methods of stretching and turning, and pulling method is for manufacturing microporous barrier
, existing polytetrafluoroethylene film is mostly cut by lathe tool.But these lathe tools are in the process made
In, it is welded to form by blade and blade, and blade is different with the material of blade, when being welded, it may occur that welding
Unstable problem, add the difficulty of welding.In order to solve Welding Problems, blade producer only has reduction edge of a knife hard alloy
Content is directly replaced with high-speed steel, and the oral area of this blade is not hard enough, for cut pure polytetrafluoroethylene (PTFE) be also possible that if
During for cutting the film containing fillers such as carbon black, glass, carbon fiber, ceramic powder, molybdenum disulfide, the easy seam broken of the blade, make
Into next film surface out-of-flatness is cut, using effect is not reached.
The content of the invention
In order to overcome the shortcomings of above-mentioned conventional art, it is an object of the invention to provide a kind of super for processing without welding
The turning cutting tool of thin wide cut polytetrafluoroethylene film, the cutter are connected and fixed with knife rest by bolt.
The purpose of the present invention is achieved through the following technical solutions：
It is a kind of to be used to process the turning cutting tool of ultra-thin breadth polytetrafluoroethylene film, including be disposed over extruding knife,
Tool section and the lower blade being arranged below, the tool section are fixed on lower blade by dismountable movable connection method.
As the preferred technical solution of the present invention, the lower blade is provided with the cutter groove for being used for installing fixed tool section, lower blade
Cutter groove side be provided with clamping screw, the tool section is fixed on lower blade by clamping screw.
As the preferred technical solution of the present invention, the extruding knife and lower blade are connected by fixing bolt with lathe respectively
And fixation.
As the preferred technical solution of the present invention, had on the extruding knife and lower blade and be easy to adjust fixed position
Bolt slot.
As the preferred technical solution of the present invention, the tool section is made up of hard alloy.
As the preferred technical solution of the present invention, the thickness of the hard alloy tool section is 10~15mm, width is 25~
30mm, length are 500~1600mm.
As the preferred technical solution of the present invention, the angle of the hard alloy tool section cutting edge is 30~40 degree.
It is described to extrude knife and lower blade by ordinary carbon steel through forging and quenching system as the preferred technical solution of the present invention
Into.
The effect of extruding knife of the present invention is the cylindrical of the extrusion blank all the time in turning process, reduces film in turning
During thickness deviation, the gap extruded between knife and tool section determines according to the thickness of turning film.The hard alloy
Tool section is to be fastened on clamping screw on lower blade, tool changing or need not dismantle blade when whetting a knife, it is only necessary to unclamps lower knife
The clamping screw of tool section is fixed with it, saves the time of school knife, convenient operation.
The beneficial effects of the invention are as follows：The present invention is used for the turning cutting tool for processing ultra-thin breadth polytetrafluoroethylene film, leads to
Cross bolt to hold blade retention clips on lower blade, the reliable fixation to blade, convenient dismounting, when saving school knife can be realized
Between, so as to solve hard alloy tool section and the problem of common blade welding.Turning cutting tool can not only be effectively ensured in the present invention
Service life, and greatly reduce the cost of charp tool, improve production efficiency.
