A continuous processing forming mold for a tapered retaining ring

Abstract

This patent discloses a continuous processing and forming mold for a tapered retaining ring, which is used for stamping and forming a retaining ring with a taper on one end surface, including a blanking die, a C-shaped hole punching die, and an upsetting die arranged in sequence along the feeding direction of the stamping profile. Corner dies, small hole punching dies, separation leveling dies, blanking dies and cut-off dies. The present invention designs a set of retaining ring continuous molds through reasonable layout, and realizes the functions of punching, upsetting, separation and leveling, blanking, and scrap cutting, thereby effectively improving the processing efficiency.

Description

technical field [0001] The invention discloses a method for forming a retaining ring, belongs to the technical field of stamping, and specifically discloses a continuous processing and forming die for a conical retaining ring. Background technique [0002] Conical retaining ring is a variety used on engines. It belongs to an open C-shaped retaining ring. One end of the C-shaped retaining ring has a taper, and the other side is required to have a flatness of 0.1. The inner and outer circles are eccentric, without burrs, and the taper , The precision requirements of flatness are higher than those of ordinary retaining rings. Conical retaining rings that do not meet the design accuracy requirements cannot be accurately installed on the engine. [0003] Generally, the manufacturing process of the conical retaining ring includes the following two methods: stamping or machining; the stamping method includes the following steps: blanking - mechanical turning taper - punching the in...

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
