Abstract
The invention relates to the technical field of CNC high-speed cutting and processing of large mould manufacturing, and specifically discloses a mould surface high-speed processing and cutting device. The device comprises a cutter hub and a cutter, and the cutter is composed of two blades; wherein the two blades can be spliced to form a semi-spherical surface, and the connection deviation is less than 0.05 mm, each blade is provided with two screw holes with a same diameter and a positioning pin, and the installation and positioning of the blades on the cutter hub are accord with the six-point positioning principle. The device has the advantages that during the high-speed processing process, the blade will not crack due to the uneven heating on the blade, the broken blade will not damage the cutter hub; at the same time, the positioning is precise and reliable, interchange precision is high, repetition precision can be guaranteed, and economy is good.
Description
Technical field
The present invention relates to CNC high-speed cutting machining large technology of die manufacturing field, refer to the die face High-speed machining topping machanism being applied to the industries such as aviation, wind-powered electricity generation, steam turbine especially.
Background technology
At present, welded topping machanism can only meet the demand of slow-speed of revolution processing, and cutting edge roundness damages the process complexity that repairs a die, and needs reconditioning cutter on special lathe.Cutter may be caused greatly to scrap as damaged.
Along with modern processing raising especially High-speed Computer number control five axle gantry machining center widely use having high requirements to cutter at die industry.What casting mould adopted is that timber is as stock, lathe adopts high-speed cutting processing profile, add the speed of mainshaft in man-hour at more than 10000rpm/min, feed speed is at 3000-5000mm/min, in such High-speed machining state, welded cutter high rotating speed add man-hour cutting edge cut produce a large amount of heat in metal cuttings to cutter hub transmission, because of welding blade adopt is brazing, the heat cut makes copper melt, and blade snaps the cutter that comes off and cannot use.
Summary of the invention
The object of this invention is to provide a kind of die face High-speed machining topping machanism, this structure have employed the cutter of mechanical fasteners blade, and cutter adopts screw clamping, solve blade to come off problem, blade exchange is convenient and simple, improves efficiency and decreases non-cutting time, and breaks down can not damage cutter hub.
To achieve these goals, present invention employs following technical scheme: a kind of die face High-speed machining topping machanism, comprises cutter hub and cutter, described cutter forms semicircle sphere by two overlap joints and the blade that sphere overlap joint error is less than 0.05mm forms; Described blade is provided with the screw hole that two diameters are identical, described blade is fixed by screws on cutter hub, is located between described cutter hub and cutter by alignment pin.
Further, the described screw hole accuracy of manufacture is that the diameter error in hole is less than 0.02mm, pitch-row error ± 0.02mm.
Further, the surperficial extra coarse degree Ra0.4 of described blade locating surface, flatness reaches whole plane and is less than 0.01mm, ensures to contact more than 90% with cutter hub locating surface.
Beneficial effect of the present invention is: after using said structure, compared with prior art, when High-speed machining, because blade non-solder is on cutter hub, and can not snap because cutting caloric value causes greatly, cutting edge comes off; Or breaks down causes cutter to scrap, need to be equipped with a large number of blade guarantee working angles and normally run.Adopt said structure only need configure the blade of some, and breaks down can not damage cutter hub, simultaneously good economy performance.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention technical scheme, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only that the present invention is in order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is cutter structure front view of the present invention;
Fig. 3 is cutter structure side view of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of die face High-speed machining topping machanism as shown in Figure 1, Figure 2 and Figure 3, comprise cutter hub (1) and cutter (2), described cutter (2) forms semicircle sphere by two overlap joints and the blade (3) that sphere overlap joint error is less than 0.05mm forms; Described blade (3) is provided with the identical screw hole (4) of two diameters and an alignment pin (5); Described blade (3) is fixed by screws on cutter hub (1), by alignment pin (5) location between described cutter hub (1) and cutter (2), the installation positioning combination principle of six-point fixing of described blade (3) on cutter hub (1), namely location technology was adopted, blade (3) bottom surface is main locating surface, blade (3) side is guide-localization face, and alignment pin estimates position till (5).When High-speed machining, only need configure the blade (3) of some, and blade (3) damage can not damage cutter hub (1).Accurate positioning is simultaneously reliable, and exchange precision is high, and repeatable accuracy is guaranteed, good economy performance.
In the present embodiment, employing two screw holes (4) installed by described blade (3), and major diameter sphere screw clamps, and clamp force distribution is even, reliable clamping, install firmly.The heat that (3) contact area of this screw and blade (3) produces when adding and also can absorbing cutting uniformly man-hour greatly, will concentrate blade (3) inequality of being heated to cause blade (3) to ftracture because of heat.Described screw hole (4) accuracy of manufacture requires that the diameter error in hole is less than 0.02mm, and screw hole (4) is apart from error ± 0.02mm.The surperficial extra coarse degree Ra0.4 of described blade (3) locating surface, flatness reaches whole plane and is less than 0.01mm, ensures to contact more than 90% with cutter hub (1) locating surface.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
