In step S1, the first metal 10 is a magnesium alloy. The receiving hole 11 is formed by punching and cutting.

Stamping specifically includes:

S101: Preheat the mold;

In at least one embodiment, the mold is preheated to 240°C to 260°C.

S102: Put the first metal 10 into a mold and punch the first metal 10 through a punching machine.

During the stamping process, a partial area of the first metal 10 is stamped and recessed to form a receiving groove.

In at least one embodiment, the punching force is 1100 KN.

In at least one embodiment, the pressing is maintained for a certain period of time after punching. Specifically, when the punching angle of the punch is 145°, the pressure is maintained for 12 seconds; when the punching angle of the punch is 180°, the pressure is maintained for 2 seconds.

In at least one embodiment, a heating element is provided in the mold, that is, the first metal 10 is heated by the method of heating in the mold during stamping, so that the temperature of the first metal 10 is uniform throughout.

During the cutting process, the first metal 10 is cut by a numerically controlled machine tool (CNC) to form the receiving hole 11.

When cutting, the bottom wall of the receiving groove is cut to form a through receiving hole 11.

In at least one embodiment, the receiving hole 11 is substantially a square hole. The receiving hole 11 includes a first receiving portion 112 and a second receiving portion 114 that are connected to each other. The first receiving portion 112 and the second receiving portion 114 are respectively formed at opposite ends of the first metal 10.

The hole wall of the receiving hole 11 is generally step-shaped, and includes a bottom wall 116 and a side wall 118. The bottom wall 116 communicates with the side wall 118.

In at least one embodiment, after the receiving hole 11 is formed, a plurality of through holes 1161 are further processed to form the bottom wall 116. The through hole 1161 is used to facilitate the passage of the gel during subsequent glue dispensing.

In at least one embodiment, after the receiving hole 11 is formed, a plurality of fixing holes 13 are further processed along the receiving hole 11 to form a plurality of fixing holes 13. Each of the fixing holes 13 also penetrates the side wall 118 and communicates with the receiving hole 11.

In at least one embodiment, after the receiving hole 11 is formed by cutting, the hole wall is further polished.

The main body 212 is received in the receiving hole 11 and carried on the bottom wall 116. Each fixing block 214 is fixed in a corresponding fixing hole 13.

Please refer to FIG. 5, which is a schematic diagram of an insert 421 in another embodiment. A bonding surface 4201 is formed on the insert 421 by processing. The bonding surface 4201 is used for fixing and bonding with the first metal 10 by dispensing glue. The width C of the bonding surface 4201 is greater than or equal to 5 mm, and a too small width will reduce the fixing force of the gel.

In the embodiment shown in FIG. 5, a glue containing groove 42011 is further processed on the bonding surface 4201. The glue containing groove 42011 is used for containing glue. The depth D of the glue container 42011 is 0.1 mm. The distance E from the glue containing groove 42011 to the edge of the bonding surface 4201 is 1.0 mm.

Please continue to refer to FIGS. 1 to 4. In step S3, the insert 21 is fixed in the receiving hole 11 through glue dispensing and pressing.

In at least one embodiment, after the insert 21 is fixed to the receiving hole 11, the insert 21 and the first metal 10 are further polished to ensure flatness. It can be understood that after polishing, polishing can be performed.

In at least one embodiment, the insert 21 is further subjected to surface treatment to improve its corrosion resistance.

In at least one embodiment, after the insert 21 is fixed to the receiving hole 11, the first metal 10 and the insert 21 are further painted.

The painting may be spray paint or the like, so that the first metal 10 and the insert 21 are integrated in appearance.

When necessary, the gap between the insert 21 and the first metal 10 can also be filled with soil, so that the first metal 10 and the insert 21 can be seamlessly connected.

In at least one embodiment, the receiving hole 11 is slightly larger than the volume of the insert 21. Preferably, the distance between the insert 21 and the side wall 118 is greater than 4 mm.

If the distance between the insert 21 and the side wall 118 is too small, it is not conducive to the polishing operation, especially when soil is filled, it is easy to accumulate soil.
