Crimping tool structure of electric reactor coil terminal

Abstract

Disclosed is a crimping tool structure of an electric reactor coil terminal. The crimping tool structure comprises an upper tool body, a lower tool body, an upper pressing die and a lower pressing die, wherein the upper tool body comprises a column body and a guiding column; a counter bore is formed in the upper end plane of the column body; a piston rod is inserted in the counter bore; a mounting plate extends perpendicularly and backwardly at the bottom of the column body; the top of the guiding column is perpendicularly fixed on the mounting plate; the lower tool body comprises a bottom plate, a stand column and a guiding plate; the guiding plate is perpendicularly connected with the upper part of the stand column; a positioning hole is formed in the guiding plate; in a working state, the guiding column is inserted in the positioning hole; the upper pressing die is fixed at the bottom end of the column body, and the bottom end of the upper pressing die concaves inwardly to form a first trapezoid-shaped groove; the lower pressing die is fixed at the top end of the stand column; a second trapezoid-shaped groove is formed in the top end of the lower pressing die; and the first trapezoid-shaped groove and the second trapezoid-shaped groove are formed in a corresponding manner. The crimping tool structure is convenient and safe to operate, accurate and unified in dimensions, firm and reliable in crimping and high in working efficiency.

Description

technical field [0001] The invention specifically relates to a reactor coil terminal crimping tooling structure. Background technique [0002] The reactor is mainly composed of an iron core and a coil. The reactor coil includes a skeleton 1, a coil 2 and a terminal 3; the crimping between the coil 2 and the terminal 3 has five major requirements: [0003] (1) The terminals 3 of two different specifications are respectively crimped with matching flat copper (or aluminum) wires. The difference between the two terminals 3 of different specifications lies in: the size of the inner hole D and the center of the bolt hole 321 to the crimping end 31 The distance L between the end faces is different; [0004] (2) Coil 2 has an odd number of layers [such as Figure 1a , Figure 1c as shown] or double-numbered layers (such as Figure 1b , Figure 1d As shown), the outlet positions of the two are different; [0005] (3) There are two crimping methods in different directions between...

AI Technical Summary

Problems solved by technology

[0007] (5) The current passing through is relatively large, and the crimping between the coil and the terminal must be firm and reliable, otherwise it will cause heat or even burn out

[0008] 1. It is difficult to keep the size requirements right, which will affect the operation of subsequent processes and even cause rework;

[0009] 2. Low production efficiency and high cost
