Description
Technical Field
The invention belongs to the technical field of machining, and particularly relates to a semi-automatic wire crimping device.
Background
The crimping type electric connector is widely applied due to the characteristics of strong environmental adaptability, high density, small volume, high electrical property, strong reliability and the like. The traditional crimping process uses a plurality of types of crimping tools and is complex in operation, and an operator needs to select a corresponding combination of crimping pliers and a positioner according to the type of a connector and the requirement of a wire gauge by referring to a crimping tool guide for operation. In order to ensure the crimping quality, an operator must repeatedly check the correctness of a crimping tool, the type of a connector and a wire gauge, so that the problems of low crimping efficiency, poor product consistency, unstable crimping quality and the like are caused.
At present, the traditional manual crimping has the defects
The drawbacks of the crimping process of the manual crimping pliers mainly include the following two points:
1. the connector which is made of harder material needs larger holding power of hands when being pressed, the natural hand strength of general female workers is insufficient, the operation is laborious, even male workers have insufficient back strength when being pressed by the hand frequently, and the efficiency is reduced;
2. the specification of the commonly used lead is more than 5, the model of the commonly used contact element is more than 6, the lead is matched with the contact element, namely the specification of the lead is correspondingly matched with the specification of the contact element, and the arrangement combination can generate a plurality of results, namely the type selection of the positioner. If the wire is not properly mated with the contact, the gap between the wire and the contact crimping barrel may be too large or too small. The gap is too small, so that the end part of the contact piece can crack after being crimped and crush the lead; if the gap is too large, the deformation of the end of the wire and the contact is too small, and the wire is easily pulled out from the terminal connecting cylinder, which affects the crimping strength. The positioner is selected to not cause over-voltage and under-voltage faults. The over-voltage can cause metal chipping and core breakage at the contact termination, and the under-voltage can cause the contact to have a gap with the wire contact end, reducing electrical performance and termination level. The strength of the indentation has a direct influence on the tensile strength and the conductivity of the crimp joint.
In order to improve the crimping efficiency and quality, a universal positioner is used, the crimping operation steps are simplified, and the universal process of the crimping operation is perfected, so that the crimping efficiency is improved by more than 90%. The pre-designed semi-automatic crimping device replaces manpower by machinery, and after parameters are set, the crimping strength and the crimping resistance are guaranteed to be high in consistency, and the crimping quality is stable and reliable.
