Continuous machining forming die for conical check ring

Abstract

The invention discloses a continuous machining forming die for a conical check ring. The continuous machining forming die is used for punch forming of a check ring with a tapered end surface on one side, and comprises a discharging die, a C-shaped hole punching die, an angle upsetting die, a small hole punching die, a separating and leveling die, a material falling die and a cutoff die which are sequentially arranged in the feeding direction of a punching profile. According to the continuous machining forming die, a set of check ring continuous die is designed through reasonable stock layout,the functions of continuous implementation of punching, upsetting, separating and leveling, material falling and waste material cutting tasks are achieved, and therefore the machining efficiency is effectively improved.

Description

technical field [0001] The invention discloses a method for forming a retaining ring, which belongs to the technical field of stamping, and in particular discloses a continuous processing and forming mold for a tapered retaining ring. 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: ...

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
