PC steel rod reducing spinning device

Abstract

A high-strength steel wire neck-spinning device comprises a lower guide rail block, a radial feeding mechanism, a rotary mechanism, an outer circle machining mechanism and a ball screw mechanism. The two sides of a steel wire are both provided with a rotary wheel and a supporting wheel of the device, when the steel wire reaches a machining position, a hydraulic cylinder piston stretches to enable the rotary wheels to move in the radial direction, and meanwhile a hydraulic cylinder of the left supporting wheel pushes the rotary wheels to move in the radial direction; when the radial mechanism moves, a motor drives a ball screw to rotate; circumferential movement of the ball screw is converted into axial movement of the guide rail block through a ball and a nut, the rotary wheel and the supporting wheel are rotated due to a motor, the radial mechanism provides rolling reduction of the rotary wheel and provides pressing force for the supporting wheel, an axial feeding mechanism provides axial displacement of a rotary wheel system, the rotary wheel squeezes the steel wire so that the steel wire can generate plastic deformation, and accordingly a steel wire outer circle is machined. By means of the device, the two ends of the steel wire can be machined at the same time, manual feeding is omitted, harm to workers caused by vibration of materials in the machining process is avoided, and steel wire machining efficiency is improved.

Description

technical field [0001] The invention relates to spinning processing equipment, in particular to high-strength steel wire outer circle diameter reducing equipment. Background technique [0002] High-strength steel wire (PC steel rod) is a kind of prestressed steel with high technical content developed by Japan's High Frequency Thermal Refining Co., Ltd. in the 1960s. It has high strength, toughness, low relaxation, and concrete grip. Strong, good weldability, upsetting forgeability, material saving and other characteristics, has been widely used in high-strength and stress or concrete centrifugal pipe piles, electric poles, viaduct piers, railway sleepers and other prestressed components abroad; at present Rolling forging is used to process the outer circle of both ends of the steel wire. During rolling forging, the bar can only be fed in and taken out from one end of the rolling forging machine. This method requires manual feeding and processing, and workers need to take it ...

[0002] High-strength steel wire (PC steel rod) is a kind of prestressed steel with high technical content developed by Japan's High Frequency Thermal Refining Co., Ltd. in the 1960s. It has high strength, toughness, low relaxation, and concrete grip. Strong, good weldability, upsetting forgeability, material saving and other characteristics, has been widely used in high-strength and stress or concrete centrifugal pipe piles, electric poles, viaduct piers, railway sleepers and other prestressed components abroad; at present Rolling forging is used to process the outer circle of both ends of the steel wire. During rolling forging, the bar can only be fed in and taken out from one end of the rolling forging machine. This method requires manual feeding and processing, and workers need to take it out after processing one end. Continue to process the other end. This method consumes manpower, is inefficient, and has certain damage to the human body.
