Abstract
The invention provides a method for milling a large diameter thread of titanium alloy or high-temperature alloy material pieces, which particularly aims at machining threads, with a large bore diameter over M30, of a difficult-to-machine material such as high-temperature alloy or titanium alloy. Due to the adoption of the digital control technology and the analysis of parameters of the large diameter thread, a thread milling cutter is determined; spiraling is mainly realized by the motions of a machine tool during machining, so the important thing of thread milling is how to control the motions of the machine tool, and particularly the thread milling has higher requirements on the machining parameters; and the method improves the machining efficiency and simultaneously ensures the thread verticality and the thread surface finishment, so the quality of thread machining is greatly improved.
Description
Technical field
The present invention relates to a kind of Screw thread process method, be specifically related to a kind of titanium alloy or high-temperature alloy material spare method for milling large diameter thread
Background technology
For difficult-to-machine materials such as high temperature alloy and titanium alloy particularly the major diameter screw thread more than the M30 process, generally all be to use the Hand tap tapping to process.
Adopt difficult-to-machine material major diameter screw threads such as manual processing high temperature alloy and titanium alloy to have a lot of difficult problems, because tapped bore is relatively large, operator's labour intensity height, and the perpendicularity of screw thread can not guarantee, therefore cause bigger rigging error, adopt manual machining screw surface quality and surperficial luminosity poor, machining accuracy is not enough, and percent defective is higher relatively.Especially for producing screw thread in enormous quantities, because manual working (machining) efficiency is low, labour intensity is huge, the percent defective that produces also can be higher relatively, machining accuracy can not guarantee, has made very big difficulty for next step assembling process, has become the bottleneck problem in the production assembling process.
Summary of the invention
The working (machining) efficiency that particularly exists in the major diameter screw thread more than the M30 at manual machining titanium alloy or high-temperature alloy material in the prior art is low, processing labour intensity is big, screw thread perpendicularity and thread surface quality can not guaranteed technical barriers, the invention provides a kind of titanium alloy or high-temperature alloy material spare method for milling large diameter thread, this method is the working (machining) efficiency height not only, reduce operator's labour intensity, and significantly reduced the percent defective that causes owing under screw thread perpendicularity and the thread surface quality.
The present invention adopts following technical scheme:
A kind of titanium alloy or high-temperature alloy material spare method for milling large diameter thread, special in the large aperture more than the M30, material is the screw thread processing of high temperature alloy or titanium alloy difficult-to-machine material, adopt Numeric Control Technology, by analysis to the major diameter thread parameter, determine screw cutter, spiral in the processing is mainly realized by the motion of lathe, so it focuses on how controlling the motion of lathe milling thread, on the parameter of processing higher requirement is arranged especially, concrete processing technology step is as follows:
In the 1st step, adopt bore cutter auger shell line bottom outlet, rotating speed S=250～500 revolutions per second, amount of feeding F=20～70 millimeter/change;
In the 2nd step, screw cutter moves to the workpiece security plane fast;
In the 3rd step, screw cutter is to depth of thread size;
In the 4th step, screw cutter is cut screw thread starting point with circular arc;
The 5th step, screw cutter is made the moving interpolation of X, Y direction around the axis of thread, do simultaneously to parallel to the axis+motion of Z direction, promptly whenever around 360 ° of axis of thread operations, pitch of edge+Z direction rising, cutter three-shaft linkage movement locus is a helix, and cutting rotational speeds is S=500～1600 revolutions per second, amount of feeding F=30～100 millimeter/change;
The 6th the step, screw cutter with circular arc from the starting point withdrawing;
In the 7th step, screw cutter retreats to the workpiece security plane fast, prepares next hole of processing.
When described security plane is meant cutter fast feed and the plane of the safe distance that keeps of part guarantees that cutter can safety movement before the incision part and after cutting out part, does not interfere and collides with part and frock.
Beneficial effect of the present invention:
When improving working (machining) efficiency, also reduced operator's labour intensity significantly, clamping of digital control processing will guarantee the screw thread perpendicularity better, reduce the component assembling error.And can not produce the waste product that causes owing to human factor under the normal condition, and its surface quality and surperficial luminosity improve greatly, and repair rate is zero, thereby improves the quality of products.The processing method of numerical control milling screw thread will replace traditional processing method.Under rational machined parameters, estimate that its working (machining) efficiency and machining accuracy improve 50%, especially for the screw thread of producing in enormous quantities, effect is more obvious.The machining titanium alloy part is saved nearly 1 times of cost, nearly 3 times of working (machining) efficiency.When the processing high temperature alloy, cost-saved nearly 20 times, working (machining) efficiency also increases.
