Problems solved by technology

[0002] The contact tip of the welding torch is connected to the head of the welding torch, which mainly plays the role of conduction and heat dissipation. The body of the contact tip of the welding torch in the prior art is generally 30mm in length, and the tail thread is an M8 standard thread. The high heat dissipation area is not enough, the corresponding heat dissipation effect cannot be achieved, and the burning rate of the contact tip is high

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as Figure 1-2 Shown is a welding torch contact tip, including a contact tip body 1, the tail of the contact tip body 1 is provided with an external thread 2 that matches the threaded hole of the contact tip seat on the head of the welding torch; the external thread 2 is an M9 elongated thread ; The length of the contact tip body 1 is set to be 35 mm longer; the tail of the contact tip body is a threaded connection part 3, and the threaded connection part 3 is set to be 14.8 mm longer.

[0012] The contact tip of the welding torch provided by the present invention has a longer body than the common contact tip, and the length of the threaded part is increased, so that the part where the contact tip is connected to the welding torch is lengthened, so that the conductive contact surface is increased by 1 / 3 compared with the prior art , which increases the cond...

Abstract

The invention discloses a welding gun contact tube which comprises a contact tube body. The welding gun contact tube is characterized in that the tail part of the contact tube body is provided with an external thread which is matched with the thread hole of a contact tube seat at the head part of a welding gun; the external thread is an M9 lengthened thread; the length of the contact tube body is arranged to be 35mm by lengthening; the tail part of the contact tube body is a thread connecting part; the thread connecting part is arranged to be 14.8 by lengthening. According to the welding gun contact tube provided by the invention, the body is longer than the general contact tube, and the length of the thread part is increased, so that the contact tube is lengthened at the welding gun connecting part; and the welding gun contact tube is excellent in contact performance and heat radiating effect aspect, is adaptive to the welding requirement well, can show the excellent performance in each aspect, especially is suitable for high-current welding of 300A above, and shows obviously in welding with aluminum; and the production efficiency of welding is improved, and the burning and damage ratio of the contact tube is reduced.

Description

technical field [0001] The invention relates to a conductive tip of a welding torch. Background technique [0002] The contact tip of the welding torch is connected to the head of the welding torch, which mainly plays the role of conduction and heat dissipation. The body of the contact tip of the welding torch in the prior art is generally 30mm in length, and the tail thread is an M8 standard thread. The high heat dissipation area is not enough, the corresponding heat dissipation effect cannot be achieved, and the burning rate of the contact tip is high. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a welding torch contact tip with better electrical and thermal conductivity. [0004] Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: [0005] The contact tip of the welding torch includes a contact tip ...
