Description

Ultralight major diameter facing cutter

Technical field

The utility model relates to a kind of ultralight major diameter facing cutter.

Background technology

As shown in Figure 1, on the BT40 machining center, during the big planar bracket of Milling Process faying face 4, adopt the minor diameter cutterhead 5 on the BT40 to carry out Milling Process, cause on the support faying face 4 and connect tool marks, and cause 4 leakage of oils of support faying face, so rework rate is very high.Support faying face 4 is generally all very wide, and generally all more than 200mm, and support faying face 4 is sealing surface, do not allow and connects tool marks, in case leakage of oil.Therefore the cutter diameter that requires processing support faying face 4 is more than D250mm; And support is except support faying face 4; The diameter of the required cutterhead of other face is all little, and the machining center of general BT40 can be accomplished, and the facing cutter weight of conventional D250mm all will be about 12kg; Promptly use light-alloy to do to such an extent that cutterhead also will be about 8kg, the weight that can bear considerably beyond the BT40 machining center.To whole to be processed of support all be accomplished on a machining center, must adopt the above machining center of BT50, and the BT50 lathe be much more expensive than the BT40 lathe.The processing of general at present employing operation break-down, the plain mille that is processed in of support faying face 4 is accomplished, and other processing content is accomplished on the BT40 machining center; But there is rigging error in substep processing, influences the perpendicularity of faying face and position, hole, and; Cutterhead 5 is whole rounded, and its diameter is merely Φ 125, and the space is too little between cutter holder; Each tool changing sheet all need take off cutterhead 5, so more time-consuming.

The utility model content

The technical problem that the utility model will solve is to provide a kind of working (machining) efficiency height, low, the lightweight ultralight major diameter of cost facing cutter.

In order to solve the problems of the technologies described above; The ultralight major diameter facing cutter that the utility model provides; Said facing cutter integral body is strip; The left and right sides of said facing cutter is all protruded outwardly and is had radian, and the place, limit, the left and right sides of said facing cutter is provided with a plurality of cutter holders respectively, is fixed with a blade on said each cutter holder.

Preferably, place, the limit, the left and right sides of said facing cutter is provided with 2 cutter holders respectively.

Further, the cutter holder of the said left and right sides is symmetrical with respect to the facing cutter center.

The ultralight major diameter facing cutter of the utility model with original discoid facing cutter, changes present strip into; Weight alleviates greatly, and the quantity of blade significantly reduces, and has practiced thrift cost; Reduced the tool changing difficulty; Shorten tool change time, reduced the machine tool accuracy requirement, improved the efficient of blade clamping.

The specific embodiment

Further specify below in conjunction with the scheme of accompanying drawing the utility model.

As shown in Figures 2 and 3; The ultralight major diameter facing cutter that the utility model provides, facing cutter 1 integral body is strip, the two arc limits up and down of original discoid facing cutter is cut away formed present strip facing cutter 1; The left and right sides of facing cutter 1 is protrusion and have a radian outwardly all; The place, limit, the left and right sides of facing cutter is provided with a plurality of cutter holders 2 respectively, is fixed with a blade 3 on each cutter holder 2, and is as shown in Figure 5.

As shown in Figure 4, the place, limit, the left and right sides of facing cutter 1 is provided with 2 cutter holders 2 respectively, and the cutter holder 2 of the left and right sides is symmetrical with respect to the facing cutter center, guarantees processing stability, has improved working (machining) efficiency simultaneously.

This facing cutter 1 adopts the lighter alloy matrix aluminum of proportion, and adopts the mentality of designing of shoulder pole formula, changes so that cutter hub reaches the gentliest.

For improving the machinability of face milling cutters, as shown in Figure 6, cutter holder 2 installation sites and facing cutter 1 center line have size to be the anterior angle of M on the facing cutter, and M is preferably 5 °, and cutter holder 2 also is that follow-up use reduces maintenance cost when abnormal loss.

The ultralight major diameter facing cutter of the utility model, the facing cutter 1 of employing strip, both sides respectively are provided with cutter holder 2; Gap between the cutter holder 2 is big, changes blade 3 convenience, has reduced the time that fixturing blade uses; Improved efficient; Find that in application efficient has improved 66%, and the workpiece of doing over again significantly reduces, make cost reduce greatly.

The ultralight major diameter facing cutter of the utility model; Because of weight alleviates greatly; In the weight range that the BT40 machining center can bear, therefore can solve the problem that under the situation that does not change lathe, solves the big plane of little machine tooling, promptly the lathe of BT40 can be processed the plane of Φ 250.

Former per tour plane is done over again 150, and two classes of every days are 300, every month 300*22=6600 spare; After adopting the ultralight major diameter facing cutter of the utility model, do not have the workpiece of doing over again, cost declines to a great extent; Every month saving cost of labor etc. reaches 4800 yuan, and annual saving cost of labor etc. reaches 5.8 ten thousand yuan;

The ultralight major diameter facing cutter of the utility model, after process rhythm improves, 21 of per tour raising the output; Former 7.5 minutes=157.5 minutes * of 21 * 2 classes/day=315 minutes/60=5.25 hour,, practice thrift 5.25*90=473 unit every day according to the per hour 90 yuan of calculating of machining center manufacturing expense; Practiced thrift 473*22=10406 unit in every month; The annual 10406*12=124872 unit that practices thrift, the workshop has 2 machining center productions at present, so 124872*2=249744 is first; Therefore through improving, can practice thrift 249744 yuan every year

The ultralight major diameter facing cutter of the utility model because of having reduced the use of cutter holder and blade, makes the use cost of blade decline to a great extent; For example, former Φ 125 cutterheads are with 9 cuttves, because product material problem; But must guarantee the machined surface quality, per tour must be changed cutter No. one time, and one two cutting edges of blade; Can use two order of classes or grades at school, so 9 cuttves of loss every day, existing ultralight major diameter cutterhead is with 4 cuttves; Improve 4 cuttves of back loss every day, practice thrift 5 cuttves at present every day, 69 yuan of blade prices/in 22 days=7590 yuan of/month * 12=91080 unit/years of * 5=345 unit/sky *; 2 device fabrications in workshop at present are so therefore 91080 yuan of * 2=182160 units can practice thrift 182160 yuan through improving annual this blade.

According to above-mentioned statistical conditions, it is 48.99 ten thousand yuan that the annual accumulative total of all kinds of expenses is practiced thrift total amount.
