Description
Technical field
The invention belongs to machinery processing apparatus technical field, be specifically related to a kind of be applicable to tungsten, the end of molybdenum pressed compact bar
Trimmer.
Background technology
Tungsten, molybdenum industry deep-processing process in, more than 20 kilograms tungsten, molybdenum sintered bars, in the follow-up operation of rolling,
The most all can there is shrinkage cavity in its afterbody, in the past, all amputates, the part producing shrinkage cavity if do not amputated, with the molybdenum rod of shrinkage cavity
During wire drawing, defect will be taken in a material, cause the mass defect of a material.Substantial amounts of giving up will be produced if amputated
Material.Through groping for many years, sum up and bar afterbody has been made a conical by its shape, so can be significantly in the operation of rolling
Reduce the waste material amputated.But how bar end makes the taper of solid shape, and factory is by after sintering and through school at first
Straight bar is put on lathe and carries out mechanical car and cut processing, but owing to bar is longer, heavier and there is also certain camber, is adding
Centre frame must be used during work, and want careful adjustment centrad.Not only working (machining) efficiency low per tour separate unit lathe process one
Root bar needs 20-30 minute, two people's operations, and the waste material formed is more, and waste material cannot effectively re-use, and causes
Bigger waste.If the bar just having suppressed out is machined out, then the powder processed can recycle again；
But owing to the bar camber that suppresses is relatively big, center bearing bracket cannot centering, just compacting bar out is more crisp, accidentally in addition
Will rupture, so cannot process on engine lathe.The most how to design a kind of novel bar trimmer, not only to carrying
High efficiency, and the yield rate improving bar is had extremely important meaning.
Summary of the invention
It is an object of the invention to provide and a kind of be applicable to tungsten, the end trimmer of molybdenum pressed compact bar, improve the one-tenth of bar

The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
The present invention is applicable to tungsten, the end trimmer of molybdenum pressed compact bar, and structure is as it is shown in figure 1, include lathe 1, on lathe 1
Being provided with pawl dish 2, pawl dish 2 is provided with special knife rest 3, and the knife rest that drags of lathe 1 is provided with air-actuated jaw 4, and tungsten, molybdenum bar material 5 are pressed from both sides
In air-actuated jaw 4, can move left and right on lathe.Pawl dish 2 is scroll chuck or chuck.
As in figure 2 it is shown, special knife rest 3 include the connection end 3-1 being stuck on pawl dish 2 and be connected end 3-1 connect knife rest
Fixing end 3-2, knife rest fixing end 3-2 is fixed with isosceles trapezoid knife rest 3-3, on two waists of isosceles trapezoid knife rest 3-3 between difference
Every being provided with multiple turning conical surface cutter 3-4, the position of the turning conical surface cutter along one of them waist of axis is adjacent with on another waist
Space between two turning conical surface cuttves is corresponding.Turning conical surface cutter 3-4 is mainly responsible for all conical surfaces in turning bars end, is rotating
During can be cut to the whole conical surface.
The upper end of isosceles trapezoid knife rest 3-3 and the junction of one of them waist are provided with rounding cutter 3-5, rounding cutter 3-5
The main conical surface of being responsible for obtains chamfering with cone junction, baseplane, and it is existing that the seamed edge at elimination right angle is easily generated limit by slight colliding with
As.
The upper end of isosceles trapezoid knife rest 3-3, is provided with two car cone baseplane cutter 3-6, is responsible for tungsten molybdenum bar conical surface end
Plane carries out car light.
One of them car cone baseplane cutter 3-6 is near the center at the upper end of isosceles trapezoid knife rest 3-3, and another car is bored
Baseplane cutter 3-6 is near the position of isosceles trapezoid knife rest 3-3 edge, and there is coincidence at the turning position of two car cone baseplane cutter 3-6,
Ensure that bar end face can be arrived by whole turning.
Turning conical surface cutter 3-4 is square alloy blade, and a blade has four blades, when after a blade passivation, permissible
Turn to use another one blade.
Rounding cutter 3-5 is that square alloy blade is processed through line cutting and mill, forms a blade with angle, folder
The angle at angle changes according to the difference of bar end edge rounding, and general angle is 135 degree here；Turning cone baseplane cutter 3-6
Using triangle alloy blade for saving Spatial General 6 R, a blade has three blades.
Turning conical surface cutter 3-4 is that four angle of throat tools are 3-edge surgical knife tool with car cone baseplane cutter 3-6, when blade is passivated
After, turn on set screw, after cutter is exchanged direction, another blade face can be used.
As it is shown on figure 3, air-actuated jaw 4 includes clamp movement end 4-2 and fixture fixing end 4-1, clamp movement end 4-2 and folder
