Embodiment Construction

[0037] The following is to process on the retarder housing whose material is ADC12 figure 1 , 2 The ring groove of the shown specifications is taken as an example to further illustrate the present invention.

[0038] In order to improve the processing efficiency, we originally designed a composite ring groove milling cutter with cemented carbide inserts. Four identical shaped inserts are evenly and symmetrically arranged around the cutter body. One pass can directly process the figure 1 , 2 Dimensional features required. The processing efficiency of this solution is significantly improved compared with the above-mentioned traditional solution, but the roughness of the bottom of the ring groove cannot meet the requirements of Ra1.6, and after two or three hundred pieces of cutting tools are processed, obvious knife lines appear on the bottom of the groove (the processing effect is as follows Image 6 As shown), the vibration of the knife will also occur from time to time.

Abstract

The invention provides a one-time forming efficient PCD cutter for annular groove machining, and aims to solve the problem that a traditional annular groove machining scheme cannot meet the requirement of mass production. Two of four PCD forming blades on a cutter body are A-type blades, and the other two of the four PCD forming blades on the cutter body are B-type blades; the two A-type blades are distributed on the same straight line, and the two B-type blades are distributed on the same straight line; chip discharging grooves of the A-type blades are formed in the bottom surfaces of the A-type blades and positioned on one sides of inner diameter cutting edges, and penetrate through the inner diameter cutting edges; chip discharging grooves of the B-type blades are formed in the bottom surfaces of the B-type blades and positioned on one sides of outer diameter cutting edges, and penetrate through the outer diameter cutting edges; when bottom surface cutting edges of the A-type bladesand the B-type blades act simultaneously, a complete annular groove bottom shape can be machined; and the inclination angles of notch cutting edges of the A-type blades and the B-type blades are both2-5 degrees. According to the invention, the machining of an annular groove and corresponding fillets can be completely finished through one-time axial cutting, and the machining precision can be met.

Description

technical field [0001] The invention relates to a high-efficiency PCD cutting tool for forming ring grooves at one time. Background technique [0002] Various types of retarder shells and rear covers usually need to process a variety of annular grooves with different specifications but similar structures (such as figure 1 , 2 The ring grooves shown), O-rings will be installed in these ring grooves later to ensure that there is no oil leakage at the inlet and outlet oil passages, so the processing requirements for these ring grooves are relatively high. [0003] At present, in mass production, for the above-mentioned ring groove processing, the traditional processing ideas generally adopted in the industry are: [0004] 1) Use D5 end mill for interpolation; [0005] 2) Design the rounded corners of the inverted notch of the special tool. [0006] The efficiency of the above-mentioned traditional solution is very low, and the size of the chamfer of the notch is very diffic...
