Description

A kind of upper and lower inner chamfer milling cutter of whole hard alloy

Technical field

The utility model relates to a kind of angle cutting tool, in particular to inner chamfer milling cutter above and below a kind of whole hard alloy.

Background technique

Angle cutting tool refers to the chamfered part for milling workpiece.There are many structures, for example radius end mill also belongs to chamfering milling Knife, milling workpiece circular arc chamfering also have the angle cutting tool faced directly certainly.

The processing request for meeting client is realized to use PCD cutter always before upper and lower inner chamfer angle milling cutter, it is whole Hard alloy cutter is because difficulty of processing is big, and there are vacancy, PCD cutter is generally welding structure, and material property is suitable for finishing Work is not suitable for the big cutting environment of machining allowance, therefore when surplus is big, cutter life is not high, increases CNC processing cost.For this purpose, It is proposed that inner chamfer milling cutter above and below a kind of whole hard alloy.

Utility model content

The main purpose of the utility model is to provide inner chamfer milling cutters above and below a kind of whole hard alloy, can effectively solve Certainly the problems in background technique.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of upper and lower inner chamfer milling cutter of whole hard alloy, including knife bar, joining rod and cutter head, the joining rod are located at knife Bar one end, the cutter head are located at joining rod one end, and described cutter head one end is inlaid with No.1 angle cutter blade, the No.1 angle cutter The blade other end is welded with No. two angle cutter blades, mutually hangs down between the No.1 angle cutter blade and No. two angle cutter blades Directly, described knife bar one end is inlaid with caudal peduncle.

Further, the No.1 angle cutter blade and No. two angle cutter blade surfaces offer cutting groove.

Further, the bit interface offers cutting slot.

Compared with prior art, the utility model has the following beneficial effects:

1, inner chamfer milling cutter is convenient right by the knife bar and joining rod of the setting being arranged up and down for this kind of whole hard alloy Entire angle cutting tool carries out material recovery, so that the use cost of entire angle cutting tool is reduced, one inlayed by cutter head one end Number angle cutter blade and No. two angle cutter blades of No.1 angle cutter blade other end welding, when convenient satisfactions processes object Required cutting angle.

2, inner chamfer milling cutter passes through No.1 angle cutter blade and No. two angle cutter blade tables to this kind of whole hard alloy up and down The cutting groove opened up is ground in face, is strengthened demand when processing to cutting member to accuracy, is opened up by bit interface Cutting slot meets common cutting demand when angle cutting tool uses.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

As shown in Figure 1-3, inner chamfer milling cutter above and below a kind of whole hard alloy, knife bar 1, joining rod 2 and cutter head 3 are described Joining rod 2 is located at 1 one end of knife bar, and the cutter head 3 is located at 2 one end of joining rod, and described 3 one end of cutter head is inlaid with No.1 angle cutter knife Sword 4,4 other end of No.1 angle cutter blade are welded with No. two angle cutter blades 5, the No.1 angle cutter blade 4 and No. two It is mutually perpendicular between angle cutter blade 5, described 1 one end of knife bar is inlaid with caudal peduncle 6.

In the present embodiment, as shown in Figure 1, being opened up by No.1 angle cutter blade 4 and No. two 5 surface grindings of angle cutter blade Cutting groove 7, strengthen demand when processing to cutting member to accuracy.

Wherein, the No.1 angle cutter blade 4 and No. two 5 surfaces of angle cutter blade offer cutting groove 7.

In the present embodiment, as shown in Figure 1, the cutting slot 8 opened up by 3 surface of cutter head, when meeting angle cutting tool use Common cutting demand.

Wherein, 3 surface of cutter head offers cutting slot 8.

It should be noted that the utility model is a kind of whole hard alloy inner chamfer milling cutter up and down, including knife bar 1, rank Extension bar 2, cutter head 3, No.1 angle cutter blade 4, No. two angle cutter blades 5, caudal peduncle 6, cutting groove 7, cutting slots 8, component is logical Component with standard component or as known to those skilled in the art, structure and principle are all that this technology personnel can pass through technical manual It learns or is known by routine experiment method, it is convenient to entire by the knife bar 1 and joining rod 2 of the setting of setting when work Angle cutting tool carries out material recovery, so that the use cost of entire angle cutting tool is reduced, the bugle inlayed by 3 one end of cutter head No. two angle cutter blades 5 for spending knife blade 4 and the welding of 4 other end of No.1 angle cutter blade, when convenient satisfaction processes object Required cutting angle, while whole structure type improves the intensity of entire angle cutting tool, passes through No.1 angle cutter blade 4 The cutting groove 7 opened up with No. two 5 surface grindings of angle cutter blade, strengthens need when processing to cutting member to accuracy It asks, the cutting slot 8 opened up by 3 surface of cutter head, meets common cutting demand when angle cutting tool uses.
