[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] like Figures 3-6 The figure is a schematic diagram of the structure of the bending mechanism for the heat dissipation spring of the utility model. The bending mechanism is usually used to Figure 1The heat dissipation spring is folded into Figure 2 the shape shown.

[0031] The heat dissipation spring comprises a spring body 22, a first extension section 23, a second extension section 24 and a through slot 25, wherein the first extension section 23 is integrally connected at one end of the spring body 22, the second extension section 24 is integrally connected at the other end of the spring body 22, and the through slot 25 penetrates the spring body 22, the first extension section 23 and the second extension section 24 in a form-fitting manner. In use, cooling water is fed into the through slot 25, thereby improving the heat dissipation effect.

[0032] The heat dissipation spring is integrally manufactured by a spring manufacturing machine Figure 1 , wherein the first extension section 23 and the second extension section 24 are both perpendicular to the axial line of the spring body 22, at this time, the heat dissipation spring is a semi-finished product, and the first extension section 23 and the second extension section 24 need to be folded into Figure 2 the shape shown.

[0033] The heat dissipation spring folding mechanism is used for folding the first extension section 23 and the second extension section 24, and can avoid folding the hollow first extension section 23 and the second extension section 24 flat, thereby avoiding blocking the through slot 25 and affecting the normal flow of the cooling water.

[0034] As shown in Figures 3-6 , the folding mechanism comprises a bottom plate 1, an abutting plate 2, a first spring slot 3, a pivot rod 4, a push plate 5, a second spring slot 6, a positioning column 7, an avoiding slot 8, a fixing plate 9, a vertical plate 10, a pressing plate 11, a baffle 12, a mounting plate 13, an adjusting bolt 14, an adjusting plate 15, an adjusting slot 16, an arc-shaped part 17, an abutting part 18, a handle 19, a through hole 20 and a pressing rod 21. The bottom plate 1 is a rectangular metal plate, which is used for fixing the remaining parts and is convenient to carry.

[0035] The abutting plate 2 is fixed on the top of the bottom plate 1 by screw fastening, the push plate 5 is movably arranged on one side of the abutting plate 2, the first spring slot 3 is arranged on the side of the abutting plate 2 close to the push plate 5, and the second spring slot 6 is arranged on the side of the push plate 5 close to the abutting plate 2. When the push plate 5 moves forward, the semi-finished spring body 22 is clamped between the first spring slot 3 and the second spring slot 6, and when the first extension section 23 and the second extension section 24 are folded, the spring body 22 is prevented from swinging and affecting the folding effect.

[0036] The mounting plate 13 is fixed on the top of the bottom plate 1 and is located on the side of the push plate 5 away from the abutting plate 2, and threaded holes are formed in the mounting plate 13, and the adjusting bolt 14 is screwed into the threaded holes and abuts against the outer side of the push plate 5. When the operator screws the adjusting bolt 14 inward, the adjusting bolt 14 will move towards the abutting plate 2 and clamp the spring body 22 between the first spring groove 3 and the second spring groove 6 (the push plate 5 and the adjusting bolt 14 are not fixedly connected, but only abut against each other, when the operator screws the adjusting bolt 14 outward, the adjusting bolt 14 is separated from the push plate 5, and the operator can pull the push plate 5 backward to remove the heat dissipation spring).

[0037] The driving mode of the push plate 5 is not limited to the mounting plate 13 and the adjusting bolt 14, and a cylinder can also be used to push the push plate 5.

[0038] The positioning column 7 is fixed on the top of the bottom plate 1 and abuts against one side of the push plate 5, the fixing plate 9 is fixed on the top of the bottom plate 1, the vertical plate 10 is fixed on the top of the fixing plate 9 and abuts against the other side of the push plate 5, and the pressing plate 11 is fixed on the top of the vertical plate 10 and abuts against the upper surface of the push plate 5.

[0039] The fixing plate 9, the vertical plate 10 and the pressing plate 11 form a limiting groove therebetween, and the push plate 5 is arranged in the limiting groove, and the movement of the push plate 5 is guided and limited by the positioning column 7 and the limiting groove, so that the position of the push plate 5 is prevented from being deviated to affect the clamping of the heat dissipation spring.

[0040] The baffle 12 is fixed on one side of the push plate 5 and moves synchronously with the push plate 5, and when the push plate 5 moves inward to clamp the spring body 22 between the first spring groove 3 and the second spring groove 6, the baffle 12 is clamped on one side of the spring body 22. When the pressing rod 21 is subsequently bent at the first extension section 23 or the second extension section 24, the baffle 12 abuts against one side of the spring body 22, so that the spring coils in the spring body 22 that are in close contact with each other are prevented from being separated.

[0041] The adjusting plate 15 is arranged on the top of the bottom plate 1 and abuts against one side of the abutting plate 2, and the adjusting groove 16 is formed in the adjusting plate 15 to adjust the position of the adjusting plate 15, so as to satisfy the bending at different positions and have higher universality.

[0042] The arc-shaped part 17 is arranged on the side of the adjusting plate 15 close to the abutting plate 2, and when the pressing rod 21 is bent at the first extension section 23 or the second extension section 24, the first extension section 23 or the second extension section 24 is bent along the arc-shaped part 17, and the arrangement of the arc-shaped part 17 can prevent the bent part from being flattened and affect the circulation of the cooling water in the through groove 25.

[0043] The abutment portion 18 is provided on one side of the adjustment plate 15 and is connected to the arcuate portion 17. When the actual bending is performed, the rotating pressure rod 21 abuts against the side of the abutment portion 18. The abutment portion 18 can block and limit the rotating pressure rod 21 to avoid excessive bending.

[0044] The avoidance groove 8 is opened on the side of the push plate 5 close to the baffle 12. The avoidance groove 8 is used to accommodate the pressure rod 21. When the push plate 5 moves inward until the spring body 22 is clamped between the first spring groove 3 and the second spring groove 6, the pressure rod 21 is set in the avoidance groove 8.

[0045] like Figure 6 As shown, the through hole 20 passes through the handle 19 and cooperates with the pivot rod 4. The pressure rod 21 is integrally connected to the bottom of the handle 19. During actual bending, the through hole 20 is inserted into the pivot rod 4, and the pressure rod 21 is inserted into the avoidance groove 8. When the handle 19 is rotated, the pressure rod 21 rotates around the pivot rod 4 as the center of the circle, and the pressure rod 21 bends against the first extension section 23 of the spring body 22 until it abuts the abutment portion 18.

[0046] To avoid excessive bending, the distance between the adjusting plate 15 and the pivot rod 4 on the side away from the abutting plate 2 is a, and the distance between the pressing rod 21 and the pivot rod 4 is b, wherein a is not less than b.

[0047] The bending principle of the bending mechanism for the heat dissipation spring of the utility model is as follows:

[0048] First, place the heat dissipation spring to be bent between the abutment plate 2 and the push plate 5, push the push plate 5 inward to clamp the spring body 22 between the first spring groove 3 and the second spring groove 6. At this time, the baffle 12 is stuck on one side of the spring body 22, and the through hole 20 is inserted on the pivot rod 4. At this time, the pressure rod 21 is inserted into the avoidance groove 8, and the handle 19 is turned. At this time, the pressure rod 21 rotates with the pivot rod 4 as the center of the circle, and the pressure rod 21 bends against the first extension section 23 of the spring body 22 until it abuts against the abutment portion 18.
