Fixed bead ring processing method

Abstract

The invention discloses a fixed bead ring processing method which can ensure locating hole machining precision, save work materials and shorten processing cycle. The fixed bead ring processing method comprises the following steps: cutting; punching a bottom hole of a 16 taper hole by a punching die; punching the inner / outer diameter of a fixed bead ring by a punching die, and processing front and rear fixed bead rings by different dimensions of moulds; softly grinding the front planes and the reverse planes of the fixed bead rings; drilling two locating holes and chamfer angles by a locating hole jig; premilling a 16-hole conical surface; softly grinding the front planes and the reverse planes of the fixed bead rings; turning the inner / outer diameters of a fixed bead rings and chamfer angles; processing round position hole and chamfer angles, including processing the front fixed bead ring: drilling round position holes and the chamfer angles by a jig; and processing the rear fixed bead ring: drilling semi-circle position holes and chamfer angles by a milling die; quenching with a continuous furnace, and tempering with a chamber furnace; hard grinding the front plane and the reverse plane of the fixed bead ring; precisely processing the diameter of the 16 bottom hole to the required demands with the aid of a bottom hole ream die and a reamer; reaming the two locating holes with a locating hole ream die; aligning 16-taper hole datum plane chamfer angles by using an explorator; precisely grinding the front plane and the reverse plane of the fixed bead ring; and boring and milling the 16-hole conical surface.

Description

technical field [0001] The invention relates to a processing method of a bead ring. Background technique [0002] The fixed bead ring is a component used on the scroll type automotive air-conditioning compressor. The publication number is CN101380711, and the publication date is a Chinese patent application on March 11, 2009, which discloses a processing method for a bead ring. The above processing method includes the following steps, step 1: cutting materials; step 2: punching Punch the bottom hole of 16 taper holes with the hole die; Step 3: Punch the inner and outer diameters of the bead ring with the punching die; Step 4: Stabilize the bead ring to eliminate processing stress; Step 5: Softly grind the front and back of the bead ring A plane; Step 6: Drill two positioning holes and chamfer with the positioning hole jig; Step 7: Drill the position hole and chamfer with the position hole jig; Step 8: Pre-mill 16-hole cone; Step 9: Soft grinding the bead The front and back...

Problems solved by technology

Moreover, since the inner and outer diameters of the front bead ring and the rear bead ring are different, if only one set of molds is used in the process of stamping the inner and outer diameters of the bead ring, the processing materials will be wasted, and the subsequent process "car setting" will be increased. Bead ring inner diameter and outer diameter and chamfering" workload

In addition, after many experiments in practice, it was found that the two processes of stabilization treatment and stress relief in the existing processing methods have little effect on improving product quality
