Material returning device of e-shaped elastic strip winding machine

Abstract

The invention discloses a material returning device of an e-shaped elastic strip winding machine. The material returning device comprises a material returning rack, a bearing seat is assembled and connected to the material returning rack, a pivotal bearing is assembled and connected to the bearing seat, a main shaft is rotationally connected to the pivotal bearing, the pivotal bearing is installed on the main shaft, and a forming mold is fixedly assembled and connected to the left side of the main shaft; the main shaft is assembled and connected with a material returning mechanism; the material returning mechanism comprises a material returning disc slidably connected to the forming die, and the right side of the main shaft is slidably connected with a material pushing disc corresponding to the material returning disc. A plurality of material pushing rods are assembled and connected between the material pushing disc and the material returning disc, and the material pushing rods penetrate through the rotary bearing; the material returning mechanism further comprises a material returning oil cylinder assembled and connected to the right side of the top of the material returning rack, a piston rod of the material returning oil cylinder is assembled and connected with a shifting fork plate, and the shifting fork plate is arranged on the right side of the material pushing disc. The device further comprises a material receiving mechanism arranged on the right side of the top of the material returning rack. By means of the design of the parts of the device, even material returning of the e-shaped elastic strips is achieved, the material taking and positioning precision is higher after material returning, and next-step forming is facilitated.

Description

technical field [0001] The invention belongs to the technical field of e-shaped elastic strip processing, and in particular relates to a material return device for an e-shaped elastic strip winding machine. Background technique [0002] The e-shaped elastic strip is a kind of locking part, which is mainly used as a locking connector on the track. Specifically, on the urban traffic track, the track and the under-rail foundation are integrated through the e-shaped elastic strip. Because of the elastic force of the e-shaped elastic strip, the use of the e-shaped elastic strip can also play a buffering role. [0003] Based on the wide range of e-type clips used, there are many public reports on the technical improvement of e-type clip processing, such as the Chinese patent application number: CN201911398826.7, which discloses an e-type clip pre-pressing machine, and The following technical solutions are proposed: [0004] The pre-pressing machine includes a host and a feeding ...

AI Technical Summary

Problems solved by technology

[0006] Based on this, in the actual processing and production process, there is often an inaccurate push point for pushing the e-shaped elastic strip during the material return process, resulting in low material return accuracy and unable to return material stably and accurately
