Description

Technical Field

[0001] The utility model relates to the technical field of spring steel wire processing, in particular to a cutting device for spring steel wire processing. Background Art

[0002] Spring steel wire is a kind of steel wire used to make springs or steel wire parts. 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 with lower requirements (referred to as mattress steel wires), spring steel wires for shock absorbers, spring steel wires for suspension springs, spring steel wires for engine valves, 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 wires can also be classified according to the manufacturing process, such as raw spring steel wires (not quenched in a lead bath before drawing), lead quenched spring steel wires, galvanized spring steel wires, oil quenched spring steel wires, etc.

[0003] A cutting device for wire processing disclosed in the Chinese utility model patent application disclosure CN 213496190 U includes a base and a crossbeam, wherein the crossbeam is fixed directly above the base through a support beam, and the support beam is fixed on both sides of the surface of the base, a first electro-hydraulic push rod is fixedly installed at the lower left side of the crossbeam, an upper knife seat is fixed at the bottom of the first electro-hydraulic push rod, and an upper cutting knife is installed in the upper knife seat, a lower knife seat is fixed on the surface of the base directly below the upper knife seat, and a lower cutting knife is installed in the lower knife seat, a support plate is fixed to the upper support of the base on the right side of the lower knife seat, and a pressure plate is fixed to the bottom of the crossbeam above the support plate through a second electro-hydraulic push rod. The utility model fixes a support plate on a base between an upper cutting knife and a lower cutting knife, and fixes a pressure plate above the support plate by a second electro-hydraulic push rod. After the steel wire is cut, it is transmitted to the right side, and then the pressure plate is pressed down, so that the unbroken steel wire can be broken by the pressure plate at the cutting position, thereby improving the cutting efficiency of the steel wire. Although the utility model has a faster steel wire cutting rate, the utility model cannot position the steel wire during cutting, and the steel wire is easily misaligned due to the friction of the cutting knife, resulting in offset in the cutting. In addition, the steel wire cut by the utility model will remain on the work table, hindering the transmission of the steel wire to be cut later. If a worker reaches out to take the cut steel wire, there will be production safety problems and reduced work efficiency. Utility Model Content

[0028] When in use, first clamp one end of the cut spring steel wire between the two conveying rollers 2, and the conveying rollers 2 are driven to rotate by a conventional mechanism such as a motor, and the spring steel wire is conveyed to the right by the friction between the two conveying rollers 2 and the spring steel wire. When the spring steel wire is conveyed to the right of the cutting knife 305 and the length meets the requirements, the spring steel wire is provided with a column 3, a top plate 301, a cylinder 302, a mounting plate 303, a limiting hole 304, a cutting knife 305, a cylinder 306, a sliding column 307, a compression spring 308 and a pressing plate 309, so that the cutting device for processing spring steel wire has the function of pressing and positioning the spring steel wire, and the cylinder 302 is started.
