Embodiment 1

[0017] Example 1, please refer to Figures 1 to 3 , the molding die that is used for high-strength " ∞ " shape part processing method, comprises upper template 11, the upper mold 12 that is fixed on the upper template 11, lower template 21 and the lower mold 22 that are fixed on the lower template 21, described upper mold 12 is provided with an upper mold cavity 13, and the lower mold 22 is provided with a lower mold cavity 23. The upper mold cavity 13 and the lower mold cavity 23 cooperate to form a "∞"-shaped inner cavity; the lower mold cavity 22 is adapted to the lower mold cavity 23 The cavities on both sides of the middle position are respectively provided with a guide plate 3 and a pair of positioning rods 4 movable relative to the guide plate 3. The positioning rods 4 are stuck between the guide plate 3 and the inner wall of the metal pipe 7; , the positioning rod 4 can roll down along the edge of the guide plate 3, and finally fall into the "∞"-shaped inner cavity.

Abstract

The invention discloses a forming die for a machining method for high-strength transverse 8-shaped parts. The forming die comprises an upper template, an upper die fixed on the upper template, a lower template and a lower die fixed on the lower template, wherein the upper die is provided with an upper die cavity; the lower die is provided with a lower die cavity; the upper die cavity is matched with the lower die cavity to form a transverse 8-shaped inner cavity; a guide plate and a pair of locating rods moving relative to the guide plate are arranged in two side cavities on the lower die adapted with the middle position of the lower die cavity respectively; and the locating rods are clamped between the guide plate and the inner wall of a metal tube. The forming die solves the problems that the machining accuracy of the current die cannot be ensured easily and the machined transverse 8-shaped parts have a short service life, and meets the requirement of a customer better.

Description

technical field [0001] The invention belongs to the field of metal stamping processing, and in particular relates to a forming die used in the processing method of high-strength "∞" shaped parts (such as chain inscribed). Background technique [0002] The "∞"-shaped part produced by the processing method of the present invention is an important connecting part on the chain, which is mainly used in high-power mechanical chains. Its precision and strength determine the quality and life of the entire chain. The existing processing methods are divided into welding type and casting type. The welding type process steps are flat strip cutting→pre-folding→primary bending→secondary bending→correction→welding sealing. The process of this process is long, the process is troublesome, and the delivery is often not up to the requirements, and the welding performance is poor, the workpiece is not easy to meet the technical requirements, and the life of the chain cannot be guaranteed. If t...
