The clamping table 20 is slidably connected to the frame 10 and can move along the long edge direction of the frame 10, so that the heat dissipation base clamped on the clamping table 20 is sequentially moved to the initial pressing assembly 40, the roller pressing assembly 50 and the milling flat assembly 60, and then the copper pipes on the heat dissipation base are sequentially subjected to initial pressing assembly, roller pressing assembly and milling flat operation.

[0040] Specifically, heat dissipation is a very important part of electronic equipment. With the popularity and continuous performance improvement of electronic equipment, heat dissipation technology is also constantly updated. At present, water-cooled heat dissipation and air-cooled heat dissipation are two common heat dissipation technologies. Among them, the heat pipe radiator in air-cooled heat dissipation has been widely used due to its high heat dissipation efficiency and stable heat dissipation effect.

[0049] As shown in Figure 1 and Figure 3 Preferably, the clamping table 20 is also provided with a clamping cylinder 27 and a clamping plate 29. The clamping plate 29 and the clamping cylinder are installed on both sides of the supporting bracket 21, so as to clamp the copper pipe which needs to be assembled, so that the copper pipe will not be separated from the heat dissipation base during the assembly process.

[0050] Specifically, the clamping plate 29 is preferably installed on the side of the clamping table 20 close to the initial pressure assembly 40, and the clamping cylinder 27 is installed on the side away from the initial pressure assembly 40.

[0056] And the second briquetting 47 can also be made of steel material with good wear resistance and toughness, so that it can protect the copper pipe from damage during the initial pressure process, and can be replaced according to the specifications of the copper pipe, or replaced after a certain period of use.

At the same time, a through hole can be provided at the position where the roller electric cylinder 54 is installed on the roller fixed plate 52, so that the piston rod can penetrate through the through hole and form a fixed connection with the roller moving plate 53 below, so that the roller electric cylinder 54 can operate to drive the roller moving plate 53 to move downward and compact the copper pipe clamped in the heat dissipation base clamping groove.

[0059] Secondly, the initial pressure cylinder 44 and the roller electric cylinder 54 can be set as the existing electric cylinder products. The electric cylinder product is a modular product designed by integrating a servo motor and a screw, which can convert the rotary motion of the servo motor into linear motion, and can convert the best advantages of the servo motor, i.e. accurate speed control, accurate rotation control and accurate torque control, into accurate speed control, accurate position control and accurate thrust control; It realizes the existing products of high-precision linear motion series.

[0062] Secondly, in order to further compact the copper pipe, the clamping table 20 can be driven by the horizontal moving assembly 30 to move back and forth multiple times under the rolling assembly 50, so that the roller 56 of the roller mechanism 55 can compact the copper pipe multiple times to make it more firmly pressed into the clamping groove of the heat dissipation base.

[0063] As shown in Figure 1 and Figure 6 Preferably, the milling assembly 60 is provided with a milling support 61, a milling guide rail 62, a milling sliding block 63, a milling screw 64, a milling motor 65 and an electric spindle 66.

The milling cutter 67 can be a product, which is a rotating cutter with one or more teeth used for milling processing. During work, each tooth cuts off the excess of the workpiece intermittently.
