Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
According to a kind of novel curved hole drill bit of Fig. 1-present invention shown in Fig. 3, including made of lathe and Thermal-resistance tool steel
Drill bit 1, the lathe include main shaft, and the spindle nose center is equipped with drill bit fastener, and drill bit 1 is mounted on drill bit fastener, institute
Stating in the middle part of drill bit 1 is cylindrical drill body 12, and upper part and lower part are respectively arranged with drillstock 11, drill point 13,1 one of drill bit at
Type, 12 diameter of drill body are greater than drillstock 11 and drill point 13, and the drillstock 11 is fixed by installs fixture and machine tool drill fastener
Connection.
The drill point 13 is threaded cylindrical body, and the lathe is provided with fixture, and the fixture is used for gripping and fixed plate
Material 2, the drill bit fastener are arranged right above fixture and can be axially moved.
A kind of boring method, the packing method the following steps are included:
A) by aluminium panels 2 to be processed, it is placed into the fixture corresponding position of lathe, fixture fixes to clamp plate 2；
B) fixture stationary state is manually checked, it is ensured that plate 2 will not shift on fixture, fall off when work；
B) start lathe, main shaft drives drill bit fastener to be moved to 2 top corresponding position of plate, and starting lathe is high by drill bit 1
Speed rotation；
C) manipulation drill bit fastener moves down, until drill point 13 protrudes into plate 2, it is drill point that the drill point 13, which protrudes into depth,
13 whole at least 90%, make between 12 lower surface of 2 upper surface of plate and drill body there are certain interval, the gap for drill point 13 with
After 2 frictional heat generation of plate, the excessive material generated after intense plastic strain deposition occurs for plate 2；
E) machine tool chief axis drives high-speed rotating drill bit 1, slowly moves from one end of plate 2 to the other end, superplasticity
The material of deformation is gradually deposited at the behind of drill bit 1, due to the lower surface and the 2 upper surface gap You Ge of plate of drill body 12, makes it
The a part of material for forming hole is overflowed, then rapid upset, play the role of removing surface film oxide, just completion is internal takes hole
A kind of method of outer surface upset welding.
The machine tool chief axis can drive the oscilaltion of drill bit fastener and move left and right, and drill bit fastener is arranged in fixture
Lower section, the drill bit 1 are mounted on drill bit fastener, and when carrying out plate 2 and processing, drill bit 1 carries out high speed rotation, drill point 13 and plate
2 frictional heat generation of material, plate 2 is gradually melted, and then drill point 13 slowly protrudes into inside plate 2, and plate 2 is drilled out one by upper surface
A hole, the drill point 13 protrude into 90% or more that the length inside plate 2 is entire length, and the length reserved is on plate 2
Surface and drill body reserve gap between 12 lower surface, and after hole depth reaches requirement, lathe drives high-speed rotating drill bit 1 by plate
One end of material 2 is mobile to the other end, and depth of the drill point 13 inside plate 2 is still kept while drill bit 1 is mobile, high when mobile
Speed rotation melts plate 2 persistently with 13 contact surface of drill point, and is forced upwardly spilling by the material that drill point 13 squeezes fusing, overflows
Material deposited in gap between 2 upper surface of plate and drill body 12,12 diameter of drill body is greater than drill point 13, therefore the material deposited
Expect the 12 lower surface upset of drill body being moved in synchronization welding, when water channel length is enough, machine tool chief axis stops rotating, and drives brill
First 1 is raised above by plate 2, and the subsequent surface to upset welding carries out polishing or polishing treatment, water channel complete the process.
A kind of novel curved hole drill bit of the present invention and processing method, structure is simple, easy to operate, additional by machine tool
Drill bit, using the processing of friction welding (FW) principle progress water channel hole, high production efficiency, production cost is low.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For the those of ordinary skill of technical field of the present invention,
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
