Portable charging regular hexagon die-exchange-free crimping machine for electronic stepless adjustment control copper-aluminum cable terminal and connecting sleeve and operation method

Abstract

The invention provides a portable charging regular hexagon die-exchange-free crimping machine for an electronic stepless adjustment control copper-aluminum cable terminal and a connecting sleeve and an operation method in the technical field of crimping of electric wires comprising coaxial cables. The portable charging regular hexagon die-exchange-free crimping machine is characterized by comprising a die-exchange-free crimping head, an adapter, a charging hydraulic tool and an electronic stroke control box, wherein the adapter is connected to a hydraulic oil cylinder of the charging hydraulic tool and then the other end is connected with the die-exchange-free crimping head; the electronic stroke control box is arranged at the upper part of the die-exchange-free crimping head; the die-exchange-free crimping head comprises a crimping head and a movable module; the crimping head is fixedly connected to the top end of the adapter; the movable module is arranged in the adapter, one end of the movable module is matched with the crimping head and the other end is connected with a push rod of the hydraulic oil cylinder; an inductor is arranged at the top of the movable module and is matched with an inductor in the electronic stroke control box; and after the two inductors generate signals, the charging hydraulic tool stops supplying electricity to the hydraulic oil cylinder.

Description

technical field [0001] The invention is used in the technical field of crimping electric wires and cables including coaxial cables, and particularly relates to the electronic control technology of crimping size and the combination with rechargeable hydraulic tools to produce a brand-new portable wire and cable crimping tool. [0002] The invention also relates to an operation method of a portable wire and cable crimping tool. Background technique [0003] The crimping of copper-aluminum wire and cable terminals has long required the use of fixed crimping dies to connect wires and cables with terminals or splice sleeves. The general crimping technology is based on the matching of stranded wires with fixed standard terminals. With a fixed compression ratio, measure to judge whether the crimping quality meets the grip force required by the wire and cable for terminal crimping. Generally, the compression ratio of the regular hexagonal crimping is 1:0.827. With the diversificatio...

Problems solved by technology

All the rechargeable hydraulic tools currently on the market use the pressure switch to achieve the function of automatic stop or automatic reset of the working pressure, which cannot accurately control the stroke of the piston, especially in the crimping. Only the crimping method needs to replace the fixed-size mold, and the fixed-size mold requires a high size for the crimping terminal or the sleeve and the wire. A slight change in size will easily lead to incomplete crimping, which may cause crimping. Large flashes after connection lead to the discharge of the cable after power transmission, or insufficient crimping size leads to insufficient grip between the terminal / sleeve and the wire, resulting in the wire and the terminal / sleeve falling off or poor contact High temperature leads to problems such as wire fire
