The invention provides an electric cutting device and relates to electric heating pipe production equipment. The electric heating pipe production equipment comprises a pipe cutting machine main body, wherein the pipe cutting machine main body comprises a support, an inserting hole is arranged in the support, a cutter is arranged in the inserting hole, the cutter can rotate relative to a copper pipe, a stress sensor for detecting stress variation parameters in the cutting process of the copper pipe and a displacement sensor for detecting displacement variation parameters in the cutting process of the copper pipe are further arranged in the inserting hole, the stress sensor and the displacement sensor are connected with a miniature processor system for carrying out a differential and integral operation function on the stress variation parameters and the displacement variation parameters, the miniature processor system is connected with a cutter state adjustment executing mechanism, and the cutter state adjustment executing mechanism is connected with the cutter. Through differential and integral operation results, the movement condition and stress condition of the copper pipe can be easily grasped in the cutting process, so that the accurate control of the cutter in the whole cutting process is realized, the damage of a resistance wire is further reduced, and the yield rate of electric heating pipes is increased.
