Embodiment Construction

[0014] see Figure 1-2 The device for high-speed impact sheet metal forming of the present invention includes a light gas compression launch system, a bullet recovery chamber 3, a support 4, a single-axis high-speed impact rod 5, a base 6 and a forming and clamping system, and the entire device adopts a transverse structure. Among them, the light gas compression launch system provides high-speed pulse power for the whole device, and is composed of a light gas compression gun 1 and bullets 2. The bottom of the light gas compression gun 1 is fixed on the base 6, and the light gas compression gun 1 is equipped with bullets 2 . A bullet recovery chamber 3 is set at a distance directly in front of the bullet 2, and the bullet after impact is recovered immediately. The bottom of the bullet recovery chamber 3 is fixed on the base 6. The rear end of the horizontally arranged uniaxial high-speed striking rod 5 stretches in the bullet recovery chamber 3, and the front of the uniaxial ...

Abstract

The invention discloses a method and a device for forming a sheet metal by high velocity impact of bullets. A light-gas compression launching system consists of bullets and a light-gas compression gun loaded with bullets. A forming and clamping system comprises a punching base, a fixer and a steel mould base. A bullet recovery chamber is arranged right ahead the bullets. The rear end of a mono-shaft high velocity impact rod arranged horizontally extends into the bullet recovery chamber. The punching base is arranged right ahead the mono-shaft high velocity impact rod. The fixer with a hole in the middle is arranged right ahead the punching base. The steel mould base is arranged right ahead the fixer. The light-gas compression gun drives the bullet to move and to collide with the rear end surface of the mono-shaft high velocity impact rod right ahead at high velocity so as to impact the punching base right ahead. A punch at the front part of the punching base impacts the plate through the middle hole of the fixer and the plate is compressed toward the steel mould base to copy the shape of mould so as to produce and form the material synchronously. And the strain rate of machined material is controlled within a range of 103-104/S-1 precisely.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a method and device based on high-speed impact forming, which is suitable for high-efficiency forming of sheet metal and also suitable for forming of sheet metal. Background technique [0002] At present, there are many methods for plastic forming of metal sheets at home and abroad. Among them, stamping forming is the most common forming method. This method is mainly used for forming low-carbon thin plates, aluminum alloy plates, copper plates and some brass plates. Compared with traditional forming methods, high-speed forming has the characteristics of high pressure, short pressure duration, and fast deformation of workpieces, so it is especially suitable for forming materials that are difficult or impossible to form by conventional methods. [0003] Typical high-speed forming methods include the following: electromagnetic forming, explosive forming, and electro-hydraul...
