Embodiment Construction

[0023] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0024] A processing method for improving the toughness of bars, including the following steps:

[0025] (1) Bar heating: Place the bar in a rotating roller in an electromagnetic induction heating furnace, and keep the rotating roller rotating at a predetermined speed. After the bar is heated to a preset temperature, the bar is heated by an infrared temperature control device The subsequent temperature is stable within the preset temperature floating range; so that the bar is heated uniformly and stably, and the bar can be kept within the preset temperature floating range before twisting, ensuring the stability and uniformity of the bar during twisting, thereby ensuring T...

Abstract

The invention relates to a processing method for improving the toughness of a bar material. According to the processing method, the bar material is heated to a preset temperature through an electromagnetic induction heating furnace, the temperature of the heated bar material is stabilized to be in a preset temperature floating range through an infrared temperature control device, so that heating of the bar material is uniform and stable, moreover, the bar material can be kept in the preset temperature floating range before twisting, the stability and the uniformity of the bar material during twisting are guaranteed, and then the strength coefficient of the formed bar material is uniform and stable; and the strength coefficient of the bar material can be improved by 20-30% by twisting the bar material by a preset angle, one end, mounted close to the rotating end of a twisting device, of the twisted and formed bar material and one end, mounted close to the fixed end of the twisting device, of the twisted and formed bar material are removed, and then the bar material is evenly cut into a plurality of sections so that the different use requirements for supporting strength and installation space in a vehicle can be met, moreover, processing is convenient, and the acquisition is easy.

Description

Technical field [0001] The present invention relates to the technical field of processing methods of bars, in particular to a processing method for improving the toughness of bars. Background technique [0002] With the rapid economic development and the penetration of environmental protection concepts, traditional fuel vehicles have gradually become popular, and modern electric vehicles have gradually entered the market. As drivers and passengers have gradually increased demand for vehicle shock absorption and stability, vehicles The demand for elastic supports and shock absorbers in the vehicle industry is also increasing day by day. Among them, due to the support strength and installation space limitations in vehicles, it is often not possible to directly use springs and other elastic parts, and replace them with elastic parts with better support strength and less installation space. However, existing materials are often not directly used as elastic parts to meet the needs of ...
