Technical Field

The invention belongs to the technical field of brazing clamps, and particularly relates to a graphite strip brazing clamp.

Background

Brazing, which is a welding method that after brazing filler metal lower than the melting point of a weldment and the weldment are heated to the melting temperature of the brazing filler metal at the same time, the liquid brazing filler metal is used for filling the gaps of solid workpieces to connect the metals. During brazing, an oxide film and oil stains on a contact surface of a base material are removed firstly, so that a capillary tube can play a role after the brazing filler metal is melted, and the wettability and the capillary fluidity of the brazing filler metal are improved. Brazing is divided into brazing and soldering according to the melting point of the brazing filler metal.

Based on the above, the inventor finds that the existing brazing fixture made of stainless steel is used for brazing in a brazing furnace, nitriding is repeatedly carried out in the brazing furnace before use, and after the brazing fixture is used for a period of time, the welding flux can form crystals on the surface of the fixture, so that the welding quality and stability of the product are seriously affected.

In view of the above, research and improvement are made on the existing structure and defects, and a graphite strip brazing clamp is provided to achieve a more practical purpose.

Disclosure of Invention

In order to solve the technical problems, the invention provides a graphite strip brazing clamp, which aims to solve the problems that the existing brazing clamp for brazing a product in a brazing furnace is made of a stainless steel material, the product needs to be repeatedly nitrided in the brazing furnace before use, and after the product is used for a period of time, a welding flux can form crystals on the surface of the clamp, so that the welding quality and the stability of the product are seriously affected.

The purpose and the effect of the graphite strip brazing clamp are achieved by the following specific technical means:

a graphite strip brazing clamp comprises a device body, wherein graphite placing plates in the left-right direction are arranged at the top and the bottom of the device body, and three fixing connecting plates which are orderly arranged in the left-right direction in the up-down direction are arranged among the graphite placing plates in a welding mode; the inside removable graphite strip of direction about all inserting spacing installation in graphite place board the place ahead.

Furthermore, the convex support bar of placing of left and right sides direction is provided with in the middle of the removable graphite strip place terminal surface, and the arris all is provided with the transition fillet about the removable graphite strip places support bar place the place ahead tip.

Furthermore, the graphite placing plate is internally provided with a rectangular hole which penetrates left and right, a stretching groove in the left and right direction is formed in the middle of the front end face of the graphite placing plate, and three limiting grooves which are orderly arranged left and right are formed in the inner side end face of the graphite placing plate.

Furthermore, the upper end face and the lower end face of the fixed connecting plate are provided with limiting convex blocks.

Compared with the prior art, the invention has the following beneficial effects:

graphite places the setting of board, and convenient removable graphite strip inserts inside and carries out spacing installation and do benefit to the damage and change, adopts removable graphite strip to avoid many harmful factors of stainless steel anchor clamps, and at first, graphite has fine stability, and chemical properties is inactive, and is corrosion-resistant, difficult reactions such as acid, alkali are difficult for taking place chemical reactions such as oxidation under high temperature, and graphite has good heat conductivility again, non-deformable under high temperature, and the heat conduction is stable.
