[0002] The welding methods of copper and copper alloys include brazing, resistance welding, fusion welding, etc. Among them, fusion welding is the most widely used method, which mainly adopts processes such as arc welding.

[0003] Traditional copper welding equipment lacks preheating, resulting in significant thermal stress during the welding process, which can cause defects such as cracks. In addition, after welding, natural cooling is often used, which has a poor cooling effect. Utility Model Content

[0004] The main purpose of the utility model is to provide a copper welding device for metal ceramic material and tungsten carbide hard alloy material, so as to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A copper welding device for metal ceramic material and tungsten carbide cemented carbide material includes a welding table with clamping assemblies on each side. An installation cavity is provided inside the welding table between the clamping assemblies, a horizontal movable plate is provided at the upper end of the installation cavity, a driving assembly is installed below the movable plate, and the driving assembly is used to drive the movable plate to translate back and forth in the installation cavity. A first groove and a second groove are provided side by side at the upper end of the movable plate, a fan that blows air upward is provided in the first groove, and an electromagnetic heating coil is provided in the second groove. A plurality of through holes connected to the installation cavity are provided on the upper end surface of the welding table. A fixed frame is provided in the center of the welding table, a vertical first cylinder is installed on the fixed frame, and a welding gun is fixedly connected to the telescopic rod of the first cylinder.

[0007] Furthermore, the clamping assembly includes a second cylinder and a pressure plate. The second cylinder is vertically installed on the welding table, and a horizontal pressure plate is fixed to the upper end of the telescopic rod of the second cylinder.

[0008] Furthermore, the drive assembly includes a dual-axis motor, a rotating shaft, and gears. The dual-axis motor is centrally mounted at the bottom of the mounting cavity. The power output shafts on either side of the dual-axis motor are each connected to a rotating shaft, and both rotating shafts are equipped with gears. A rack is provided at the bottom of the movable plate, meshing with the gears.

[0009] Furthermore, guide rails are installed on the left and right sides of the installation cavity, and sliding grooves that cooperate with the guide rails are opened on both sides of the movable plate.

[0010] The present invention also includes other components that enable the copper welding device for cermet and tungsten carbide to function properly. These devices and components utilize conventional techniques in the art. Furthermore, devices and components not otherwise specified in the present invention utilize conventional techniques in the art, such as the first and second cylinders described herein. During implementation, appropriate device or component models may be selected based on the specific work scenario.

[0011] The working principle of the present invention is as follows: During welding, the telescopic rod of the second cylinder in the clamping assembly shortens, and the pressure plate moves downward to clamp the weld. Simultaneously, the dual-axis motor is activated, which drives the gears to rotate via the rotating shaft. The gears and racks mesh with each other, moving the second groove of the movable plate directly below the weld. The electromagnetic heating coil in the second groove is energized to preheat the weld. After preheating, the welding gun descends to perform welding. After welding is completed, the dual-axis motor drives the first groove of the movable plate to move directly below the weld, and the fan in the first groove is activated.
