Problems solved by technology

[0003] The existing anti-metal fatigue spring steel wire has a thick diameter, high strength, and requires a smooth cut, so the required shearing force is very large. At the same time, the production of the spring steel wire is continuous. If the spring steel wire produces a slight If there is a long pause, the steel wire in the furnace will be overburned, resulting in decarburization and scrapped. However, most of the steel wire shearing devices now have spring steel wires that have a long pause in production, which reduces the production of spring steel wires. efficiency

[0030] Please refer to Figure 1-Figure 4 , in the first embodiment of the present invention, a kind of anti-metal fatigue spring steel wire processing technology, comprises the following steps:

[0031] S1: First of all, the distance between the lower rotating roller and the upper rotating roller can be adjusted by using the electric lifting lever in the spring steel wire processing equipment to adapt to different sizes of steel wires;

[0032] S2: Then, use the cooperation of the lower rotating roller and the upper rotating roller in the spring steel wire processing equipment to roll the steel wire in advance to prevent the steel wire from bending. After cutting, each section is not the same length, which affects the production quality of the spring;

[0033] S3: Finally, use the up and down movement of the movable tool holder in the spring steel wire processing equipment to cut the spring steel wire, and ensure the continuity of spring steel wire production, and fix the pos...

Abstract

The invention relates to the technical field of springs, in particular to an anti-metal fatigue spring steel wire machining technology. The machining technology comprises the following steps that firstly, the distance between a lower rotating roller and an upper rotating roller can be adjusted by utilizing an electric telescopic rod in spring steel wire machining equipment to adapt to steel wires with different sizes; then, the lower rotating roller and the upper rotating roller in the spring steel wire machining equipment are used in a cooperative mode, a steel wire is rolled straight in advance, and the situation that the production quality of springs is affected due to the fact that the steel wires are bent and the lengths of all sections are different after shearing is avoided; and finally, the spring steel wire is sheared through the up-down movement of a movable tool rest in the spring steel wire machining equipment, the continuity of spring steel wire production is guaranteed, the position of the steel wire is fixed through a steel wire fixing device, and the problems of dragging, irregular notches and the like during shearing are solved. The anti-metal fatigue spring steel wire machining equipment has the advantages of being simple in structure, convenient to use, rapid in shearing and capable of guaranteeing the production continuity of the spring steel wire.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a metal fatigue-resistant spring steel wire processing technology. Background technique [0002] Spring steel wire is a kind of steel wire used to make springs or steel wire shapes. According to the different uses of springs, there are many types of spring steel wires required for making springs, such as spring steel wires for mattress springs, spring steel wires for shock absorbers, spring steel wires for suspension springs, and engine valve wires. Spring steel wires and spring steel wires for camera shutters, etc., although there is no unified standard classification name, the quality requirements of these steel wires are different. Spring steel wire can also be classified according to the manufacturing process, such as raw drawn spring steel wire (without lead bath quenching before drawing), lead quenched spring steel wire, galvanized spring steel wire, oil quenched spring st...
