Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
Referring to Fig. 3, a kind of mechanical type quick-replaceable type aluminium ingot two milling combination cutter of the present embodiment is mainly used in the cutting of metal aluminium ingot, two milling combination cutter comprises 2 symmetrically arranged milling cutters altogether, and 2 similar for the shape and structure of milling cutter, mainly comprises tool rest 1, cutter head 2 and cutter head quick change construction.Referring to Fig. 2, in the present embodiment, the cutter head of tool rest 1 installs inclined-plane 13 relative to the angle of inclination beta of tool rest plane 12 is 51 ° (angle that namely cutter head is installed between inclined-plane 13 and tool rest plane 12 is 51 °).This inclination angle is designed to an innovation of the present embodiment, and inventor points out, at the beginning of the tool rest 1 of two milling combination cutter designs, it is designed to angle [alpha] as shown in Figure 1 according to the inclination angle that cutter head is installed inclined-plane 13 by working experience for many years, and α equals 66 °.The tool rest 1 at this inclination angle once used after a while, but in actual production process, inventor always finds the less effective of Tool in Cutting aluminium ingot, and main manifestations is required great effort for cutting, surface quality is poor, and cutter edge also often bursts apart.Inventor is in order to solve the problem, the inclination angle starting to attempt installing cutter head inclined-plane 13 in conjunction with knowhow is improved, during this, inventor attempted multiple angle, but all to occur or cutting effect is poor or cutting edge easily bursts apart or the various problem such as cutter head and the easy drawing crack of tool rest, it is more suitable within the scope of 50 ~ 55 ° relative to the angle of inclination beta of tool rest plane 12 that final inventor determines that cutter head installs inclined-plane 13, the wherein best results when angle of inclination beta is 51 °.When test of many times show that angle of inclination beta is 51 °, in the cutting process of aluminium ingot, suffered by cutter head 2, cutting resistance value is minimum, and tool rest 1 thickness near cutter head 2 is also more suitable, the junction not easily drawing crack of tool rest 1 and cutter head 2, again because cutter head 2 is stressed lighter, blade mouth crack phenomenon also greatly reduces, and cutter is durable in use, have also been obtained raising to the cutting quality of aluminium ingot.
Another innovation of the present embodiment is tool rest 1 and cutter head 2 to be improved to the mode removably connected from the mode that traditional welding is integrated, this mainly considers that the volume of two milling combination cutter is larger, tool rest 1 and cutter head 2 are welded as a whole, after cutter head 2 blade mouth crack, when using emery wheel to carry out sharpening reparation to cutting edge, the impact of cutter head 2 pairs of emery wheels is comparatively large, easily causes danger and cutting edge reconditioning operation is not easily controlled.Cutter head mounting groove has been offered on the top that the present embodiment installs inclined-plane 13 at cutter head, cutter head 2 is inserted in this cutter head mounting groove, by cutter head quick change construction, cutter head 2 is fixed, described cutter head quick change construction comprises special hold-down bolt 3 and supports head screw 4, one end of special hold-down bolt 3 is elbow, and the sidewall of this special hold-down bolt 3 offers fixing hole 31; Described cutter head 2 offers installing hole 21, accordingly, also hold-down bolt hole 15 is offered in the cutter head mounting groove of tool rest 1, special hold-down bolt 3 through installing hole 21, hold-down bolt hole 15 by spacing for cutter head 2 in cutter head mounting groove, simultaneously, the position of the corresponding fixing hole 31 of upper surface of tool rest 1 offers to head screw hole 16, inserts fixing hole 31 internal fixtion cutter head 2 to head screw 4 by supporting head screw hole 16.The present embodiment, to the ingehious design of cutter head 2 and tool rest 1 syndeton, can not only ensure that cutter head 2 is reliably connected with tool rest 1, and the installation of cutter head 2, dismounting are also very convenient.So, when repairing cutter edge on the one hand, can be pulled down by cutter head fast and carry out emery wheel reconditioning to it separately, reconditioning operation is more easily controlled and be there will not be danger, the cutter head that fast changeable is new in damaged cutter head repair process on the other hand, and the unlikely cutter that affects uses.In addition, cutter head 2 is designed to parallelepiped structure by the present embodiment, and be provided with 2 cutting edges in two side opposite the angles of parallelepiped, cut in aluminium ingot process, first can change after a cutting edge breakage and use another cutting edge, after two cutting edges all breakage, dismantle reconditioning again, the service time of cutter head 2 is longer, save replacing construction, improve production efficiency.
The present embodiment, in order to obtain cutting effect better, extends cutting-tool's used life, has also carried out following structure and has improved:
One, the present embodiment adopts deep-slotted chip breaker 11 transition tool rest plane 12 and cutter head to install inclined-plane 13, and the cambered surface radius of deep-slotted chip breaker 11 is 10mm, and the design of deep-slotted chip breaker 11 can increase the intensity of tool rest 1, contributes to extending cutting-tool's used life.
Its two, the present embodiment devises an overmoving surface 17 at the upper surface of tool rest 1, and this overmoving surface 17 tilt angle gamma is with respect to the horizontal plane 9 ° (referring to Fig. 2 and Fig. 3).The present embodiment design overmoving surface 17, mainly because two milling combination cutter in use needs continuous rotation, the upper surface of its tool rest 1 always can encounter workpiece because of reasons such as vibrations, causes the upper surface of tool rest 1 impaired, affects cutting-tool's used life.Inventor is by repeatedly attempting finally determining, when the tilt angle gamma of overmoving surface 17 with respect to the horizontal plane (state when the corresponding tool rest 1 of horizontal plane is normally positioned over ground herein) is 9 °, the upper surface of tool rest 1 can never encounter workpiece.
They are three years old, the present embodiment is provided with the first clear chamfered groove 142 of clear chamfered groove 141, second and the 3rd clear chamfered groove 143 in cutter head mounting groove, 3rd clear chamfered groove 143 is for holding a cutting edge of cutter head 2, second clear chamfered groove 142 is for holding cutter head 2 limit adjacent with cutting edge, and the first clear chamfered groove 141 is for holding cutter head 2 wedge angle.The cross section of the described second clear chamfered groove 142 and the 3rd clear chamfered groove 143 is semicircle, and radius is 2mm.The effect being designed with two aspects of the clear chamfered groove of the present embodiment, first radius is the effect that the clear chamfered groove 142 of semicircle second of 2mm and the 3rd clear chamfered groove 143 can play fixing cutter head 2, coordinate special hold-down bolt 3, fixing to head screw 4, can ensure that, in cutter use procedure, cutter head 2 does not produce and rocks; Secondly, clear chamfered groove also can play the effect of buffering, protection cutting edge.
The present embodiment is improved by above-mentioned a series of structure, ensure that aluminium ingot two milling combination cutter has good result of use, puts in production and can greatly enhance productivity, and not high to the improving cost of two milling combination cutter, is convenient to apply in producer.
