Problems solved by technology

This crimping tool has structural defects such as oil leakage, oil circuit cracking, oil circuit blockage, etc., and the tool is large in size and heavy in weight, making it inconvenient to carry and use
Another example: Chinese patent CN101497186A discloses an electromechanical crimping tool that realizes crimping action through mechanical transmission. This electromechanical crimping tool realizes crimping force increase and transmission through three-stage gear reduction, and the force increase is not enough Large, and there is no automatic control of the crimping process, the operator needs to rely on the main switch to control the crimping action process, the practicality of this tool has problems, it cannot meet the crimping of general pipelines, and it is basically not suitable for engineering use

Abstract

The invention discloses an electric press plier which comprises a shell, wherein a switch is arranged on the shell, the inside of the lower end of the shell is provided with a power supply and a circuit control device, the inside of the upper end of the shell is provide with a motor and a speed reducer, a drive gear is arranged on an output shaft of the speed reducer and mutually matched with a driven gear fixedly arranged on a screw barrel, the screw barrel is sleeved on a screw in the shell and mutually and helically matched with the screw, a knocking block is arranged on the screw, the shell is internally and respectively provided with a front stroke switch and a rear stroke switch which are mutually matched with the knocking block, a digital display device is arranged on the rear end of the shell, and the front end of the screw is mutually matched with a plier assembly arranged at the front end of the shell. The invention has the advantages of avoidance of structural defects of hydraulic compression joint, convenience for compression joint, small volume, light weight, convenience for carrying, high automation, convenience for use and management because the compression joint frequency is measured by a control system and displayed by the digital display device, and the like.

Description

technical field [0001] The invention relates to an electric crimping pliers, in particular to an electric crimping pliers for crimping pipe joints or cables. Background technique [0002] Existing electric crimping pliers for crimping pipe joints or cables, such as the crimping tool disclosed in Chinese patent CN1274433C, realizes hydraulic compression through a hydraulic mechanism. This crimping tool has structural defects such as oil leakage, oil circuit cracking, oil circuit blockage, etc., and the tool is large in size and heavy in weight, so it is inconvenient to carry and use. Another example: Chinese patent CN101497186A discloses an electromechanical crimping tool that realizes crimping action through mechanical transmission. This electromechanical crimping tool realizes crimping force increase and transmission through three-stage gear reduction, and the force increase is not enough Large, and there is no automatic control of the crimping process, the operator needs ...
