Description

Technical Field

[0001] The utility model relates to a diffusion welding graphite electrode, belonging to the technical field of graphite electrode improvement. Background Art

[0002] In the prior art, the welding steps of soft copper bar products generally include first fixing the graphite electrode to the positioning block, visually correcting the positions of the upper and lower graphite electrodes, then placing the soft copper bar product on the surface of the lower graphite, and starting to weld the soft copper bar product. Such an operation has the advantage of simple processing of the graphite electrode, but the product correction time is long, and the usage frequency of a single graphite electrode is only one, resulting in high grinding and procurement costs of the graphite electrode. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a diffusion welding graphite electrode with short product correction time, capable of using a single graphite electrode four times, and capable of reducing the grinding and procurement costs of the graphite electrode.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is as follows:

[0005] A diffusion welding graphite electrode includes an upper graphite electrode and a lower graphite electrode arranged up and down. Positioning holes are respectively formed in the upper graphite electrode and the lower graphite electrode. A positioning pin is installed in the positioning holes arranged up and down. A soft copper bar product is placed between the upper graphite electrode and the lower graphite electrode. An upper electrode panel is arranged above the upper graphite electrode. A first upper positioning block and a second upper positioning block for respectively positioning the upper graphite electrode are installed below the upper electrode panel. A lower electrode panel is arranged below the lower graphite electrode. A first lower positioning block and a second lower positioning block for respectively positioning the lower graphite electrode are installed above the lower electrode panel.

[0006] The first upper positioning block and the second upper positioning block are L-shaped, and the first upper positioning block and the second upper positioning block are respectively located at two diagonal positions of the upper graphite electrode.

[0007] The first upper positioning block and the second upper positioning block are fixed on the upper electrode panel by pin nails.

[0008] The first lower positioning block and the second lower positioning block are L-shaped, and the first lower positioning block and the second lower positioning block are respectively located at two diagonal positions of the lower graphite electrode.

[0009] The first lower positioning block and the second lower positioning block are fixed on the lower electrode panel by pin nails.

[0010] There are two positioning holes on the upper graphite electrode, symmetrically distributed on both sides of the upper graphite electrode. There are two positioning holes on the lower graphite electrode, symmetrically distributed on both sides of the lower graphite electrode.

[0011] A base is connected to the upper surface of the upper electrode panel and the lower surface of the lower electrode panel.

[0012] The upper graphite electrode and the lower graphite electrode are symmetrically mirror - set in the up - down direction.

[0013] The beneficial effects of the present utility model: The present utility model provides a diffusion - welded graphite electrode. By installing a first upper positioning block and a second upper positioning block for respectively positioning the upper graphite electrode under the upper electrode panel, and a first lower positioning block and a second lower positioning block for respectively positioning the lower graphite electrode on the upper surface of the electrode panel, the graphite electrode can be positioned four times and can be used four times. Compared with visual correction, the product correction time is short. In addition, since a single graphite electrode can be used four times, the grinding and procurement costs of the graphite electrode can be reduced. Description of the Drawings
