An ultra-high-strength fastener and its manufacturing process and device

Abstract

The invention discloses an ultra-high-strength fastener and its manufacturing process and device. The processing technology in this scheme includes a raw material treatment, b cold heading treatment, c thread processing cold treatment, and d surface treatment, wherein the thread processing cold treatment is applied to the device The thread rolling processing assembly is connected with an oil cooling assembly for cold processing of bolts, and one side of the thread rolling processing assembly is connected with a transfer assembly for processing and transporting the processed bolts one by one. Processing, since the thread rolling processing in this scheme includes the transfer components used to transfer the bolts one by one, it is convenient to process the processed bolts one by one, which reduces the extrusion accumulation during bolt processing and avoids the gap between the bolt and the nut. The extrusion wear improves the processing strength between the bolt and the nut. At the same time, the oil cooling component is used to facilitate the oil cooling treatment during the thread processing, so as to avoid the wear of the outer ring thread and the thread processing mechanism during thread processing.

Description

technical field [0001] The invention relates to the technical field of fastener processing, in particular to an ultra-high-strength fastener, a manufacturing process and a device. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments All kinds of fasteners can be seen on the , chemical industry, instruments and supplies, etc., which are the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people also refer to a class of fasteners with existing national standar...

AI Technical Summary

Problems solved by technology

[0003] Fasteners need to undergo cold heading, thread processing and surface treatment during processing. When processing fasteners such as bolts, thread processing must be performed on the surface of the bolts through a thread rolling machine. The existing The bolt fastener has a thread structure at the rod-shaped part, and a mounting cap at the top of the rod. When threading the bolt fastener, the rod-shaped part of the processed bolt needs to be pushed into two opposite thread rolling threads. The barrel is easy to be pressed into a thread shape, but because there is a nut structure at the top of the bolt, the nut bears against the thread rolling barrel, so it is not convenient to push the rods of the bolts into the thread rolling barrel one by one for threading Processing, when the previous bolt processing is completed, the bolt is not taken out, at this time, the subsequent bolt will squeeze the processed bolt, causing the wear between the bolt rod and the nut to increase, causing the bolt to be processed at the nut Insufficient strength, for this reason, we propose an ultra-high-strength fastener manufacturing device
