DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 4As shown, the utility model is a forming jig for bending a temperature equalizing plate, comprising an upper cover plate 1 connected to a base 2, a punch 3 fixedly connected to the upper cover plate 1, a first movable die 4 connected to the upper right side of the base 2, a second movable die 5 provided on the left side of the first movable die 4, the second movable die 5 is connected to a fixed block 7 through a first spring 6, a connecting rod 10 is connected to the right side of the first movable die 4, and the connecting rod 10 is connected to a fixed rod 12 on the base 2 through a second spring 11. The upper cover plate 1 and the base 2 are respectively connected to the hot pressing machine tool. The hot pressing machine tool is started to clamp the tooling upper cover plate 1 and the base 2. The temperature-averaging plate is bent under the action of force. The first movable mold 4 and the second movable mold 5 on the base 2 are in the same plane and are matched with the temperature-averaging plate. The rotating shafts on both sides of the first movable mold 4 are movably connected with the axial holes on the base 2; when the temperature-averaging plate is bent, the punch 3 presses the temperature-averaging plate, and the second movable mold 5 moves downward accordingly. The right side of the first movable mold 4 also moves downward during the pressing process. The first spring 6 and the second spring 11 play a buffering role on the one hand, and can reset the second movable mold 5 and the first movable mold 4 respectively on the other hand. It is convenient and efficient to use and has good practicality.

[0021] The utility model further comprises that the first movable mold 4 is connected to the base 2 through a support column 9. The right side of the first movable mold 4 is supported by the support column 9, and the length of the support column 9 can be adjusted according to the bending requirements, thereby adjusting the height of the first movable mold 4, so that the bending tooling can be widely used.

[0022] The utility model further has positioning posts 8 fixedly connected to the upper surface of the second movable mold 5 and symmetrically arranged. The symmetrically arranged positioning posts 8 can be sleeved and fixed to the temperature balancing plate to prevent the temperature balancing plate from sliding in the mold and causing damage.

[0023] The utility model further has the sliders on both sides of the second movable mold 5 connected to the tracks on the base 2. The sliders on the second movable mold 5 are slidably connected to the tracks on the base 2 to avoid shaking of the second movable mold 5, and facilitate bending of the temperature equalizing plate, which has good practicality.

[0024] In the present invention, the cross section of the male mold 3 is a trapezoid. The male mold 3 with a trapezoidal cross section can be set according to the bending requirements of the temperature equalizing plate, and the upper bottom side is an inclined surface.

[0025] The utility model further provides that the left edge of the first movable mold 4 is provided with a rounded corner, and the range of the rounded corner is R10-R50. The rounded corner on the left side of the first movable mold 4 can avoid damage to the temperature equalizing plate during the bending process.

[0026] The utility model further has two second springs 11 and two fixing rods 12, and the two second springs 11 are arranged in a triangle. The two second springs 11 are respectively connected to the fixing rods 12 and form a triangle, which has a shock absorbing effect on the one hand and is conducive to the reset of the first movable mold 4 on the other hand.

[0027] The description and application of the utility model here are illustrative and are not intended to limit the scope of the utility model to the above-described embodiments.
