Amorphous alloy hot press forming device and method and hot press formed part

Abstract

The invention discloses an amorphous alloy hot press forming device and method and a hot press formed part. The hot presses forming device and method and the hot press formed part comprise the following steps that the device is provided and comprises a bottom plate, a heating device, a lower module and an upper module, and a containing space for containing amorphous alloy plate materials is formedbetween the upper module and the lower module; the surface of the amorphous alloy plate materials is sprayed with a high-temperature-resistance coating; a heating plate is heated to the superplastictemperature of the adopted amorphous alloy plate materials; the amorphous alloy plate materials are fed into the material heating plate and heated to the superplastic temperature of the amorphous alloy plate materials; the amorphous alloy plate materials start to be subjected to the forming or sheet metal working procedure; and the high-temperature-resistance coating on the surface of the amorphous alloy plate materials is removed. By adopting the method, gas in a cavity does not need to be replaced with inert gas, hardware continuous die blanking, punching, flanging, shaping and other processes can be carried out, parts in complex shapes can be manufactured, production time is short, the efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of die-casting molding of amorphous alloys, in particular to a hot-press forming equipment, method and hot-press formed parts of an amorphous alloy. Background technique [0002] The publication number is "CN104259432A", and the Chinese invention patent application titled "A hot-press forming method and a hot-press forming machine for an amorphous alloy" discloses a hot-press forming method and a hot-press forming machine for an amorphous alloy, The hot press forming machine for amorphous alloy includes a vacuum chamber, a die-casting part arranged in the vacuum chamber, and an infrared heating device arranged outside the vacuum chamber for heating the vacuum chamber; the die-casting part includes a die-casting chamber and a die-casting The inert atmosphere pipeline connected to the cavity; the die-casting cavity is provided with an upper mold, a lower mold, an upper middle plate group arranged above the upp...

AI Technical Summary

Problems solved by technology

[0003] When this form of amorphous alloy hot-press forming method and hot-press forming machine are used as amorphous alloy sheet equipment with equal wall thickness, the cavity first needs to be sealed; secondly, the air in the sealed cavity should be replaced with an inert gas, In order to prevent the material from being oxidized when the amorphous alloy sheet is heated, it takes a lot of time to heat the amorphous alloy material in the mold cavity each time; secondly, the above-mentioned patent uses a vacuum method to make the amorphous alloy sheet adsorb on the surface of the cavity, so many processes of the stamping die cannot be carried out, such as blanking, punching, flanging, shaping and other processes

This processing method and equipment can only form simple products at one time, which has many restrictions on the shape of the product, and the forming time is long and the cost is high, so it is not suitable for mass production
