[0019] Please see Figure 1-5 This utility model provides a quartz crystal lead wire bending tool, including a fixed frame 2, a hydraulic cylinder 1 screwed onto the fixed frame 2, and the piston rod of the hydraulic cylinder 1 screwed onto the working plate 8. At the same time, bending pressure rollers 12 are installed on both sides of the bottom of the working plate 8, and pressure rods 15 are installed on the inner side of both sets of bending pressure rollers 12. The bottom of the pressure rods 15 is screwed onto the limiting plate 10.
[0020] The bottom of the fixed frame 2 is screwed to the workbench, and the mold 6 is fixed in the middle of the workbench. At the same time, positioning grooves 7 are opened on both sides of the surface of the mold 6, and quartz crystal resonators 11 are installed inside the two sets of positioning grooves 7. Two sets of leads are set on the quartz crystal resonator 11. The limiting plate 10 moves downward and presses the roots of the two sets of leads on the quartz crystal resonator 11.
[0021] Working principle: First, the quartz crystal resonator 11, whose leads need to be bent, is placed on the positioning groove 7. At this time, the external switch of the hydraulic cylinder 1 is activated, and the piston rod of the hydraulic cylinder 1 drives the working plate 8 to move downward, so that the limiting plate 10 and the bending pressure roller 12 move downward synchronously. The limiting plate 10 presses the root of the lead of the quartz crystal resonator 11, and the bending pressure roller 12 bends the outer extension of the lead of the quartz crystal resonator 11, rolling over the crystal lead during rolling. The bending is achieved. During the bending process, the root of the lead will not generate stress on the surrounding sealing glass, avoiding the quartz crystal resonator 11 from leaking and failing in subsequent temperature shock tests, or affecting the long-term reliability of use.
[0022] In a preferred embodiment, guide seats 4 are fixedly installed at both ends of the working plate 8, and guide holes are opened inside the guide seats 4. At the same time, guide rods 3 are inserted into the guide seats 4, and guide rods 3 are fixedly installed on the fixed frame 2.
[0023] like Figure 1 As shown: When the working plate 8 is raised and lowered, the guide rods 3 are inserted into the guide seats 4 at both ends, which can limit and guide the working plate 8 during the raising and lowering process, so as to prevent the working plate 8 from tilting during the raising and lowering process, and so that the limiting plate 10 and the bending pressure roller 12 can accurately act on the leads of the quartz crystal resonator 11.
[0024] In a preferred embodiment, two sets of limiting cylinders 9 are evenly installed on the working plate 8, and a sliding groove 13 is opened inside the limiting cylinder 9. At the same time, the sliding groove 13 is adapted to the size of the slider 5, and the slider 5 is slidably disposed inside the sliding groove 13.
[0025] like Figure 1 and Figure 5 As shown: the working plate 8 drives the limiting plate 10 and the bending pressure roller 12 to move downward. When the limiting plate 10 moves downward and covers the root of the lead wire, the bending pressure roller 12 continues to move downward and bends the outside of the lead wire. At this time, the slider 5 on the limiting plate 10 compresses the spring 14.
[0026] In a preferred embodiment, a pressure rod 15 is inserted into the middle of the inner part of the limiting cylinder 9, and a slider 5 is fixedly installed on the pressure rod 15. At the same time, a spring 14 is installed on the slider 5, and the spring 14 is inserted into the pressure rod 15.
[0027] In a preferred embodiment, the limiting plate 10 is a rectangular structure made of plastic, and two sets of pressing grooves are provided at the bottom of the limiting plate 10. The cross-section of the two sets of pressing grooves is arc-shaped, and the bottom of the limiting plate 10 covers the two sets of lead wires respectively through the two sets of pressing grooves.
[0028] like Figure 1-5 As shown: The bottom of the limiting plate 10 is covered by two sets of pressure grooves on the two sets of leads respectively; by setting the pressure grooves, the friction between the limiting plate 10 and the leads can be increased, and no misalignment will occur when the limiting plate 10 presses down on the root of the leads.
[0029] In a preferred embodiment, the limiting plate 10 and the bending pressure roller 12 move downward synchronously, the limiting plate 10 presses the root of the lead wire of the quartz crystal resonator 11, and the bending pressure roller 12 bends the outer extension of the lead wire of the quartz crystal resonator 11.
[0030] like Figure 1-5 As shown: The lead wire bending forming tool can ensure that the root of the lead wire is clamped and fixed first during the lead wire bending process of the quartz crystal resonator 11. The lead wire bending is carried out by the bending pressure roller 12 to reduce stress.
[0031] The quartz crystal resonator 11 is fixed onto the positioning groove 7. The positioning groove 7 allows for quick positioning and installation of the quartz crystal resonator 11 onto the mold 6.
