Description

Technical Field

[0001] The utility model relates to the technical field of door panel processing, in particular to a machining milling cutter. Background Art

[0002] In the production and processing of door panels, there is a process of using a milling cutter to process the lock hole, hinge groove, top groove on the top surface of the door panel, and bottom groove on the bottom surface of the door panel. In the traditional door panel processing technology, 5 machining equipment are required. The 5 machining equipment are distributed in sequence along the conveying direction of the door panel, and are used to process the vertical surface of the lock hole, the horizontal surface of the lock hole, the top groove, the bottom groove and the hinge groove in sequence. They are single machines with single functions, and the whole processing system is costly and occupies a large factory space.

[0003] In order to reduce the cost of the entire processing system and reduce the space occupied by the entire processing system, an improvement plan is proposed to integrate 5 machining equipment into a door panel processing center. Based on this, the requirements for the milling cutter are very high and need to run at high speed to meet the speed-up processing requirements. However, the existing milling cutter has the following defects:

[0004] 1. If a traditional spiral edge milling cutter is used, although the processing speed is faster, it is easy to break the edge during the processing;

[0005] 2. If a traditional straight-edge milling cutter is used, although it is not easy to break the blade, its chip removal is poor and the processing speed cannot be increased. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a machining milling cutter which has a faster machining speed and does not break the cutting edge.

[0007] To achieve the above-mentioned purpose, the utility model provides a machined milling cutter, comprising a connected milling cutter shank and a milling cutter blade, and a plurality of spiral blades formed on the periphery of the milling cutter blade, the plurality of spiral blades being distributed at intervals along the circumference of the milling cutter blade, a chip groove being formed between two adjacent spiral blades, and along the cutting direction of the milling cutter blade, the distances of the plurality of spiral blades from the axis of the milling cutter blade decrease successively, so that the cutting amount of the plurality of spiral blades increases successively.

[0008] Furthermore, the rotation directions of the plurality of spiral blades are the same.

[0009] Furthermore, there are three spiral blades; along the cutting direction of the milling cutter blade, the three spiral blades are respectively a first spiral blade, a second spiral blade and a third spiral blade, and the first spiral blade, the second spiral blade and the third spiral blade are distributed at 120° intervals along the circumference of the milling cutter blade.

[0010] Furthermore, the cutting amount of the first spiral blade is 1 / 3 of the total cutting amount, the cutting amount of the second spiral blade is 2 / 3 of the total cutting amount, and the cutting amount of the third spiral blade is the total cutting amount.

[0011] Furthermore, the cutting amount of the first spiral blade is 1 / 5 of the total cutting amount, the cutting amount of the second spiral blade is 3 / 5 of the total cutting amount, and the cutting amount of the third spiral blade is the total cutting amount.

[0012] As described above, the machining milling cutter involved in the utility model has the following beneficial effects:

[0013] The distances between the several spiral blades and the axis of the milling cutter blade in the present application decrease successively, and the radial direction of the milling cutter blade forms a layered structure, so that the cutting amount of each spiral blade is different and increases successively, that is, the latter spiral blade continues to cut on the basis of the cutting of the previous spiral blade. After adopting this structure, the rotation speed of the machining milling cutter during cutting is effectively improved, and the feed speed of the machining milling cutter can also be improved, and finally the processing time of a single door panel can be shortened; at the same time, the load of each spiral blade can also be reduced, which also reduces the vibration of the machining milling cutter during cutting and avoids chipping. In addition, the actual cutting amount of each spiral blade is a part of the total cutting amount of the machining milling cutter during one cutting. Compared with the traditional milling cutter, the cutting amount of each spiral blade is reduced, thereby improving the surface smoothness of the processed part. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0025] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0026] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.

[0027] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0028] The present application provides a machining milling cutter for installation in a door panel machining center to machine the lock hole, hinge slot, top slot and bottom slot on the door panel. In order to shorten the machining time of a single door panel, the machining speed of the machining milling cutter needs to be improved. Based on this, Figure 1 and Figure 2As shown, the machining milling cutter provided by the present application includes a connected milling cutter shank 10 and a milling cutter blade 20, and a plurality of spiral blades 30 formed on the periphery of the milling cutter blade 20. The milling cutter shank 10 and the milling cutter blade 20 are coaxial and are an integrally formed structure. The plurality of spiral blades 30 are distributed at intervals along the circumference of the milling cutter blade 20, and a chip groove 40 is formed between two adjacent spiral blades 30. In particular, along the cutting direction of the milling cutter blade 20, the distances of the plurality of spiral blades 30 from the axis A of the milling cutter blade 20 decrease successively, so that the cutting amount of the plurality of spiral blades 30 increases successively. That is to say, along the cutting direction of the milling cutter blade 20, the first spiral blade 30 is at the largest distance from the axis A of the milling cutter blade 20 and its cutting amount is the smallest; the distance between the second spiral blade 30 and the axis A of the milling cutter blade 20 is reduced by one distance compared to the first spiral blade 30, and the second spiral blade 30 continues to cut on the basis of the cutting already done by the first spiral blade 30, and the cutting amount of the second spiral blade 30 will increase compared to the first spiral blade 30; and so on.

[0029] Therefore, the machining milling cutter in the present application has a layered structure in the radial direction of the milling cutter blade 20, so that the cutting amount of each spiral blade 30 is different and increases in sequence. The use of this structure has the following advantages: 1. It effectively improves the rotation speed of the machining milling cutter during cutting, which can also improve the feed speed of the machining milling cutter, so that the machining milling cutter has a faster processing speed, and ultimately shortens the processing time of a single door panel; 2. It reduces the load of each spiral blade 30, which also reduces the vibration of the spiral blade 30 during cutting by the machining milling cutter, and avoids chipping; 3. The actual cutting amount of each spiral blade 30 is a part of the total cutting amount of the machining milling cutter during one cutting, which reduces the cutting amount of each spiral blade 30 compared to the traditional milling cutter, thereby improving the surface smoothness of the processed part and reliably ensuring the processing accuracy.

[0030] Furthermore, the spiral blades 30 have the same rotation direction.

[0031] Furthermore, the number of the spiral blades 30 on the milling cutter blade 20 is determined according to actual needs, and may be three, four, five, or more. Figure 1 and Figure 2In the view shown, there are three spiral blades 30, which are defined as the first spiral blade 31, the second spiral blade 32 and the third spiral blade 33. The first spiral blade 31, the second spiral blade 32 and the third spiral blade 33 are distributed at intervals of 120° along the cutting direction of the milling cutter blade 20. The distance between the first spiral blade 31 and the axis A of the milling cutter blade 20 is L1, the distance between the second spiral blade 32 and the axis A of the milling cutter blade 20 is L2, and the distance between the third spiral blade 33 and the axis A of the milling cutter blade 20 is L3, then L1>L2>L3. When cutting, for the same cutting position on the door panel, the first spiral blade 31 cuts first, then the second spiral blade 32 cuts, and finally the third spiral blade 33 cuts. The first spiral blade 31 cuts a part, the second spiral blade 32 cuts a part, and the third spiral blade 33 cuts a part, so that the cutting position on the door panel is cut once.

[0032] Furthermore, when the machining milling cutter performs one cutting, there are multiple ways to set the cutting amount of the first spiral blade 31, the second spiral blade 32 and the third spiral blade 33. Two preferred setting ways are provided below.

[0033] Method 1: The cutting amount of the first spiral blade 31 is 1 / 3 of the total cutting amount, the cutting amount of the second spiral blade 32 is 2 / 3 of the total cutting amount, and the cutting amount of the third spiral blade 33 is the total cutting amount, and the total cutting amount is the cutting amount of the machining milling cutter in one cutting. For example: the cutting amount of the machining milling cutter in one cutting is 6mm, then the cutting amount of the first spiral blade 31 is 2mm; the cutting amount of the second spiral blade 32 is 4mm, which includes the cutting amount of 2mm of the first spiral blade 31; the cutting amount of the third spiral blade 33 is 6mm, which includes the cutting amount of 4mm of the second spiral blade 32.

[0034] Method 2: The cutting amount of the first spiral blade 31 is 1 / 5 of the total cutting amount, the cutting amount of the second spiral blade 32 is 3 / 5 of the total cutting amount, and the cutting amount of the third spiral blade 33 is the total cutting amount, and the total cutting amount is the cutting amount of the machining milling cutter in one cutting. For example: the cutting amount of the machining milling cutter in one cutting is 10mm, then the cutting amount of the first spiral blade 31 is 2mm; the cutting amount of the second spiral blade 32 is 6mm, which includes the cutting amount of 2mm of the first spiral blade 31; the cutting amount of the third spiral blade 33 is 10mm, which includes the cutting amount of 6mm of the second spiral blade 32.

[0035] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
