Description

TECHNICAL FIELD

[0001] The utility model relates to the field of head processing technology more specifically, it relates to a forming device for head processing. BACKGROUND

[0002] In the field of modern industrial head processing, hot stamping forming technology as an important metal forming process, is widely used in the manufacture of various precision parts, however, the traditional hot stamping technology has many technical bottlenecks and process defects, first, in the traditional stamping process, the operator usually places the profile heated to high temperature in the die directly for stamping forming, the most serious problem of this simple and direct stamping mode is the lack of accurate guiding mechanism, leading to the upper die and lower die not easy to accurately align in the stamping process, position deviation and deformation are prone to occur, seriously affect the size accuracy and geometric quality of the final product, and the traditional hot stamping technology generally ignores the cooling process of the profile after stamping, cooling as a crucial link in hot working process, its efficiency directly determines the internal organization structure and surface quality of the product, however, the existing technology often adopts extremely primitive and inefficient cooling mode, not only the cooling speed is slow, this unreasonable cooling process not only prolongs the production cycle, but also may lead to uneven residual stress in the profile, seriously affect the mechanical properties and service life of the product.

[0003] In order to improve the cooling efficiency, part of the advanced equipment begins to open the heat dissipation groove in the inner side of the upper die and the lower die, and tries to realize heat exchange cooling through the flow of cooling liquid in the heat dissipation groove, however, this seemingly advanced cooling scheme still has fatal defects, the most prominent problem is that the cooling liquid conveying speed lacks effective adjustment mechanism, leading to the cooling process completely depends on the fixed liquid flow rate, in actual production, different materials and different thickness of the profile often need differentiated cooling strategy, but the existing technology cannot realize accurate cooling speed regulation, can only passively accept a single cooling mode, this technical limitation seriously restricts the flexibility and adaptability of hot stamping process.

[0004] More worrying is that even if part of the equipment tries to introduce cooling liquid speed regulation device, its technical scheme is extremely simple, these adjustment mechanisms generally have the problems of simple structure and extremely low stability, in the actual stamping working environment, the vibration of the equipment when closing the die and the impact of the pipeline can cause the flow rate regulated carefully to fail instantly, this unreliable adjustment system not only cannot play the expected function, but also will bring more uncertainty, bring huge technical risk to precision machining, the instability of cooling liquid conveying directly affects the cooling quality, ultimately will inevitably reduce the consistency and reliability of the product.
