Shrapnel bending machine

Abstract

The invention discloses a shrapnel bending machine, which belongs to the technical field of shrapnel bending. Including the frame, the frame is equipped with a positioning tool suitable for the injection molded part, the injection molded part is injected with a shrapnel, and the upper part of the positioning tool is provided with a pressure block driven by the first power device and used to compress the injection molded part; and the shrapnel The frame on the corresponding side is provided with a rotating shaft driven by the second power unit, and the rotating shaft is provided with a turning arm that deviates from the axis of the rotating shaft. Bending rollers are installed on the turning arm. The cross section does not intersect with the axis of the rotating shaft; in the initial state, the shrapnel is located above the bending roller, and the center of the pre-bending fillet of the shrapnel is basically located on the axis of the rotating shaft; both the first power device and the second power device are connected to the electronic control unit. The structure is simple, one-step bending is realized and the precision is high, the production efficiency is greatly improved, the production cycle is saved, the product quality is effectively guaranteed, the requirements of mass production are met, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of shrapnel processing, in particular to a shrapnel bending machine. Background technique [0002] In electro-acoustic components, in order to solve the problem of reliable and convenient passage of two components, elastic contact is usually used, that is, the contact of one component adopts the method of shrapnel. When the two components are in contact, the shrapnel will be elastic under pressure. Deformation, so that it can be in close contact with the contact of another component under the action of elastic force, so as to realize reliable connection and facilitate disassembly and assembly. [0003] At this stage, the shrapnel is mostly used as an insert and injected on the injection molded part by in-mold injection molding technology. Affected by the technology, it is impossible to realize the bending before injection molding. Bending) is generally divided into two methods: manual bending and multi-step...

AI Technical Summary

Problems solved by technology

Manual bending has low efficiency, poor quality, and high cost, and is mostly used in small batch production; while multi-step batch bending needs to decompose the entire bending process into more than three steps for stamping and bending. The process is cumbersome and the efficiency is low. Unable to meet the demand for large-scale delivery
