Continuous forming die for connecting terminal

Abstract

A continuous forming die for a connecting terminal comprises a forming core bridge, a male die, a swing female die, a bearing column, a stripper ejector rod and a limit ejector rod. The forming core bridge is a rod-shaped horizontal cantilever, the swing female die is hinged to a cantilever end on the outer side of the forming core bridge and is capable of swinging around a hinge shaft, a concave cavity is arranged on the lower side of the outer end of the swing female die, the male die is arranged below the outer end of the swing female die, a projection opposite to the concave cavity is arranged at the upper end of the male die, the bearing column is arranged above the outer end of the swing female die and is abutted to the outer end of the swing female die in a downwardly movable manner, the stripper ejector rod is arranged above the inner end of the swing female die and is abutted to the inner end of the swing female die in a downwardly movable manner, and the limit ejector rod is arranged in a body of the forming core bridge and outwardly abutted to the side of the inner end of the swing female die. The continuous forming die can be used for continuously bending and punching the closed annular electrical connecting terminal with inner convex ribs on a pair of dies, so that machining efficiency is improved, product cost is reduced, and the quality of the connecting terminal is improved.

Description

technical field [0001] The invention relates to a processing device for electrical metal parts, in particular to a continuous molding die for a closed ring electrical terminal with an inner convex rib, belonging to the technical field of metal stamping processing. Background technique [0002] my country is the fastest growing low-voltage electrical appliance market in the world. According to statistics from the China Electrical Equipment Industry Association, the average annual compound growth rate of the domestic low-voltage electrical appliance market was over 15% from 2000 to 2010. In 2010, the sales revenue of the entire industry was about 43.7 billion yuan; Markets such as India and Russia also maintain an average annual compound growth rate of less than 10%. However, my country's electrical appliance manufacturers generally have problems of low manufacturing technology and low technical content of products, resulting in a lack of competitiveness in the international ma...
