Description
Technical field
The utility model is related to a kind of cutting tool, particularly a kind of instrument for cutting multiple material honeycomb sandwich construction product.
Background technology
Multiple material honeycomb sandwich construction floor has been widely used in the multiple fields such as Aeronautics and Astronautics, is needed during production by ground
Plate sheet fabrication is into required given size and shape.Conventional rib tooth milling cutter tool is currently mainly used to carry out floor board
Cutting, the logical excessive speeds of milling cutter smash cellular mode and come milling floor.
But there are some such shortcomings in the cutting of rib tooth milling cutter：1st, because milling cutter smashes honeycomb by side edge, process
Product burr afterwards is more, and otch is irregular, it is necessary to be further processed to burr；2nd, rib tooth milling cutter diameter is small, less than 1cm, its
The cutting mode smashed with side edge, processing feeding is slow, and cutting efficiency is low；3rd, under high rotating speed use state, the rib of diameter very little
Tooth milling cutter is cut repeatedly, causes quick abrasion.
Utility model content
Utility model purpose：In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of multiple material honeycomb interlayer of cutting
The instrument of structural fabrication, reduces the burr produced after cutting, improves cutting efficiency, alleviates tool wear.
Technical scheme：A kind of instrument for cutting multiple material honeycomb sandwich construction product, including angle head, circular saw, the angle
Spend head one is input, and other end is output end, and the input is tied with the output end structure positive presentate output in 90 °
Structure, the circular saw and the output end assembly connection.
Optimal, a diameter of 160~200mm of the circular saw, sawtooth number is 50~60.According to multiple material honeycomb interlayer
The characteristics of structure and sheet metal thickness, design circular saw diameter and sawtooth number, in processing, the linear velocity of circular saw is moderate, and sawtooth can
With the share loads in cutting process, the abrasion of cutter is efficiently reduced, the life-span of cutter is improved.
Optimal, the sawtooth of the circular saw is that the alternate angle between cross structure, two neighboring sawtooth is 150 °, described
The rake angle of sawtooth is 10 °, the angle of back of tooth is 30 °.According to the characteristics of multiple material honeycomb sandwich construction and sheet metal thickness, such angle
Design is sharper when cutting sheet material, and the burr that this tooth Profile Machining product is produced is few, smooth-sided compression candles.
The circular saw passes through flange assembly connection with the output end.
The circular saw includes the saw blade and the sawtooth positioned at outer ring positioned at inner ring, and the saw blade is high-speed steel material, institute
Sawtooth is stated for hard alloy steel material, the saw blade welds to form circular saw with the sawtooth.
Beneficial effect：Compared with prior art, the utility model has the advantages that：The multiple material honeycomb folder of zigzag tooth circular saw processing
Rotating fields, obtained product burr is few, smooth-sided compression candles, product one-shot forming quality-improving；Circular saw rate of cutting can be brought up to
2000mm/min, improves efficiency of numerical control (NC) machining, and tool wear is few, long lifespan；Convenient mounting and clamping when using, reduces tool change time.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limit scope of the present utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
A kind of instrument for cutting multiple material honeycomb sandwich construction product, as shown in Figure 1, including angle head 1, circular saw 2, angle
Degree one of first 1 is input 3, and other end is output end 4, input 3 and the structure of output end 4 positive presentate export structure in 90 °, just
Property is good, circular saw 2 with output end 4 is by flange assembly connection and locks, input 3 is connected with machine tool chief axis.
As shown in Figure 2-4, a diameter of 160~200mm of circular saw 2, sawtooth number is set to 50~60.Circular saw
Sawtooth is cross structure, is staggered between tooth and tooth, and the alternate angle α between two neighboring sawtooth is 150 °, before the tooth of sawtooth
Angle beta is 10 °, angle of back of tooth γ is 30 °.The design of circular saw is according to the characteristics of multiple material honeycomb sandwich construction and sheet metal thickness.First,
The diameter design of circular saw, can prevent using rotate when interfere machine tool chief axis, cutting when angle head will not with it is to be cut
Sheet material is interfered, and will not also collide machine tool chief axis, and can obtain moderate linear velocity, and cutting speed can reach 2000mm/
Min, improves cutting efficiency, and compared to the cutting of existing rib tooth milling cutter, cutting speed can improve about 3 times.Second, rational sawtooth
Number, can in cutting process share loads.The coordinate design of circular saw specification, can efficiently reduce tool wear, improve
Cutter life.3rd, zigzag tooth and its special angle are designed, sharper when cutting sheet material, can make what processing product was produced
Burr is few, smooth-sided compression candles.
Circular saw includes the saw blade and the sawtooth positioned at outer ring positioned at inner ring, and saw blade is high-speed steel material, and sawtooth is hard
Steel alloy material, saw blade welds to form circular saw with sawtooth.
In use, the output end assembling fastening of circular saw and angle head, then the input of angle head and machine tool chief axis are connected
Connect, circular saw and sheet material to be cut are perpendicular, promote cutting.The time is saved in convenient mounting and clamping, tool changing.
