Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1 to 4, a shaping mechanism of a bending die comprises an upper die holder 1, an upper padding plate 2, an upper clamping plate 3, a stop plate 4, an upper stripper plate 5, a lower die plate 6, a lower padding plate 7, a lower die holder 8, a push rod 9, a shaping positioning block 10, a shaping sliding block 14, a limiting block 15 and a spring 16, wherein the push rod 9 is connected to the upper clamping plate 3 and the stop plate 4 in a penetrating manner, the bottom of the push rod 9 is abutted to a rectangular groove 150 at the top of the limiting block 15, the shaping positioning block 10 is arranged on the lower padding plate 7, a leaning block 13 is arranged in the middle of the shaping positioning block 10, the limiting block 15 is connected to the upper stripper plate 5, the shaping sliding block 14 is connected to the limiting block 15 in a sliding manner, the spring 16 is arranged in a U-shaped groove 140 on the side surface of the shaping sliding block 14, and the top end of the spring 16 is connected to the bottom end of the limiting block 15, the bottom end of the spring 16 is connected to the U-shaped groove 140.
