Description

Technical Field

[0001] The invention relates to the technical field of brazing, in particular to a tool brazing heat treatment tool. Background Art

[0002] Brazing refers to a welding method in which the solder with a lower melting point than the weldment and the weldment are heated to the melting temperature of the solder at the same time, and the gap of the solid workpiece is filled with liquid solder to connect the metals. When brazing, the oxide film and oil stains on the contact surface of the parent material must be removed first, so as to facilitate the capillary to play a role after the solder melts, increase the wettability and capillary fluidity of the solder. In the field of cutting tools, the tool head and the blade are often connected by brazing. Before welding, it is necessary to add flux and dry and heat treat it.

[0003] During the heat treatment process, the cutter head and blade with added brazing flux need to be placed in a drying box for drying and heat treatment, and then taken out for brazing. However, the existing drying device generally adopts rotary drying for uniform heating. As a result, during the drying process, the blade sometimes deviates from the cutter head or even detaches from the cutter head, resulting in the subsequent brazing position being unstable. Summary of the invention

[0004] In order to solve the problem in the prior art that the blade and the cutter head are easily separated during the brazing heat treatment process, which affects the firmness of subsequent brazing, the present invention provides a tool brazing heat treatment tool.

[0011] The insert rod is inserted into each of the limit insertion holes, and the outer wall of the insert rod is in contact with the outer wall of the blade.

[0012] By adopting the above technical scheme, the position of the cutter head is restricted from the inside by utilizing the movement of the arc-shaped sleeve, so as to prevent the cutter head from moving arbitrarily during processing and the blade from falling off, and the movement of each arc-shaped sleeve is controlled by utilizing the expansion clamping mechanism, so that the tooling is suitable for clamping different types of cutter heads, thereby improving the applicability of the tooling, and utilizing the threaded rotation connection between the threaded rod and the threaded sleeve in the blade clamping mechanism to adjust the extension length of the threaded rod to press the blade, so as to prevent the blade from shaking during the heat treatment and detaching from the cutter head, thereby ensuring the stability of the clamping, and fixing both the cutter head and the blade, effectively solving the problem that the blade and the cutter head are easily separated during the heat treatment, which affects the firmness of the subsequent brazing, and then the blade is limited at multiple points by the insertion rod in conjunction with the threaded rod, thereby improving the firmness of the limit.

[0013] Optionally, the expansion clamping mechanism includes a support platform and a shaft rod, the shaft rod is rotatably connected to the support platform and passes through the support platform, the support platform is fixedly connected to the inner side of the connecting plate and is arranged on the inner side of each arc-shaped sleeve, the shaft rod is fixedly connected to two driving gears respectively located on the upper and lower sides of the support platform, the upper surface of the support platform is fixedly connected to two slide rails a, the lower surface of the support platform is fixedly connected to two slide rails b, the slide rails a and the slide rails b are both slidably connected with sliders, one end of the slider is fixedly connected to the inner wall of the arc-shaped sleeve, and the outer walls of the different sliders are respectively provided with tooth plates a and tooth plates b meshing with the driving gears.
