Description

Technical Field

[0001] This utility model relates to the field of milling cutter processing technology, and more specifically, to a PCB milling cutter holder tempering device. Background Technology

[0002] The milling cutter used in PCB manufacturing is also called a router cutter. It is used in the post-processing of PCB manufacturing. Its main purpose is to cut the finished circuit board into individual PCS or SPNLs. PCB milling cutters are mainly used for cutting. The cutting edge and the direction of force are in the transverse direction, which can easily cause deformation of the PCB milling cutter shank. During the production of PCB milling cutters, the PCB milling cutter shank needs to be tempered to enhance its hardness, wear resistance and strength. Common methods include quenching, annealing and tempering.

[0003] For example, patent CN221854703U discloses a PCB milling cutter holder tempering device, including a high-frequency quenching equipment body and a spiral inductor. The spiral inductor is made of a hollow copper tube, which runs through the top and bottom and forms an induction heating zone at the center of the interior. In order to facilitate the support of the PCB milling cutter holder in the spiral inductor, when the high-frequency quenching equipment body is started, the alternating magnetic field formed in the spiral inductor generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, strong on the surface and weak in the interior, which can achieve the effect of rapid heating of the workpiece surface.

[0004] When the above-mentioned device is in use, it can not only improve the support stability of the PCB milling cutter holder during quenching and heating, prevent it from deviating from the center of the spiral inductor, and ensure a uniform heating effect, but also keep the operator away from the main body of the equipment during the quenching and heating process, reducing the risk of being burned and thus improving operational safety. However, the operation is relatively cumbersome when changing the PCB milling cutter, which affects the work efficiency of the staff. Utility Model Content

[0026] This utility model provides a PCB milling cutter holder tempering device, such as... Figure 1 and 2 As shown, it includes a high-frequency quenching equipment body 1, a support plate 5 is provided on the upper side of the outer end face of the high-frequency quenching equipment body 1, and a spiral induction coil 9 is provided on the outer end of the support plate 5.

[0027] The high-frequency quenching equipment body 1 is provided with electric telescopic rods 6 on both sides of the support guard plate 5 on the end face of the high-frequency quenching equipment body 1, and a support guide rail 11 is provided on the lower side of the support guard plate 5 on the outer end face of the high-frequency quenching equipment body 1. The high-frequency quenching equipment body 1 is provided with a control panel 2 at the upper end.

[0028] The control panel 2 is equipped with a display screen 3 and control buttons 4 on its end face. It can control the high-frequency quenching equipment body 1 to work through the control panel 2. The high-frequency quenching equipment body 1 will drive the spiral cleaning coil 9 to work. The electric telescopic rod 6 is provided with mounting ear plates 7 on both sides of its lower end. The outer end of the mounting ear plate 7 is provided with multiple hexagon socket bolts 8. The threaded rods of one end of the multiple hexagon socket bolts 8 can pass through the inside of the mounting ear plate 7 and be screwed into the inside of the high-frequency quenching equipment body 1, making the installation of the electric telescopic rod 6 more convenient. The mounting ear plate 7 is connected to the outer shell of the high-frequency quenching equipment body 1 through the hexagon socket bolts 8.

[0029] The high-frequency quenching equipment body 1 has a support base plate 10 on the lower side of the support guide rail 11 on the outer end face of the body. The upper end of the support base plate 10 is provided with a damper 12, and the outer end face of the damper 12 is provided with a support spring 13.

[0030] The spiral induction coil 9 and the electric telescopic rod 6 are both connected to the control panel 2 via wires, and the control panel 2 is electrically connected to an external power source via a power cord.

[0031] like Figure 3 and 4 As shown, a support block 14 is movably installed on the upper side of the outer end face of the support guide rail 11. The support block 14 can be supported by the damper 12 and the support spring 13. The operator can drive the electric telescopic rod 6 to work through the external control device.
