Upsetting-extruding forming method for conical check ring

Abstract

The invention discloses an upsetting-extruding forming method for a conical check ring. The upsetting-extruding forming method is used for punch forming of a check ring with a tapered end face on oneside, and comprises the following steps:1, taper angle forming of the check ring is realized by using an angle upsetting die; and 2, leveling of the horizontal end face and the taper angle end face ofthe check ring is achieved through a separating and leveling die, and the check ring is separated from the waste materials. According to the upsetting-extruding forming method, high-precision machining of the check ring is achieved by conducting the angle upsetting procedure and the separating and leveling procedure on the check ring, and meanwhile the machining efficiency is effectively improved.

Description

technical field [0001] The invention discloses a retaining ring forming method, which belongs to the technical field of stamping, and specifically discloses a conical retaining ring upsetting extrusion forming method. Background technique [0002] The tapered retaining ring is a variety used on the engine. It belongs to the open C-shaped retaining ring. The end face of the C-shaped retaining ring has a taper, and the flatness of the other end requires 0.1. The inner and outer circles are eccentric, without burrs, and the taper The accuracy requirements of flatness and flatness are higher than those of ordinary retaining rings, and the tapered retaining rings that do not meet the design accuracy requirements cannot be accurately installed on the engine. [0003] Generally, the processing technology of the tapered retaining ring includes the following two methods: stamping forming or machining forming; the stamping forming method includes the following steps: blanking - mechan...

Problems solved by technology

[0002] The tapered retaining ring is a variety used on the engine. It belongs to the open C-shaped retaining ring. One side of the C-shaped retaining ring has a taper, and the other side has a flatness requirement of 0.1. The inner and outer circles are eccentric, without burrs, and the taper The precision requirements for flatness and flatness are higher than those of ordinary retaining rings, and the tapered retaining rings that do not meet the design accuracy requirements cannot be accurately installed on the engine

[0003] Generally, the processing technology of the tapered retaining ring includes the following two methods: stamping forming or machining forming; the stamping forming method includes the following steps: blanking - mechanical turning taper - punching inner shape - punching two small holes - completing the product; machining The forming method includes the following steps: blanking-car outer circle-car taper-car inner circle-punching two small holes-finishing the product; the above two methods are cumbersome in process and long in cycle. pcs / month) tapered retaining ring can hardly be prepared
