Reinforced spool and manufacturing method thereof

Abstract

The invention provides a reinforced spool and a manufacturing method thereof. The reinforced spool has a spool base body made by a hot-pressing technology in an integrated manner, interlocking pieceswhich are assembled on flange surfaces of the spool base body by spot welding, and an axle tube assembled between axes of the interlocking pieces by spot welding, and positioning steps which are usedto place the interlocking pieces and are formed by turning on the flange surfaces. The spool has the following advantages: (1) an original three-segment combined structure of two sheets of flanges anda cylinder is adjusted to the integrated spool base body, gaps do not exist, and a wire clamping and breaking problem is prevented; (2) the flange surfaces being provided with the positioning steps by turning, the positioning steps being used to place the interlocking pieces, the spool is assembled by spot welding, and spool integrated concentricity is effectively improved; (3) with the axle tubeas datum, a wire winding surface is formed by turning, ensuring that concentricity is controlled to be lower than 0.1 mm, and axis run-out of the flange surface is controlled to 0.1 mm from original1 mm; (4) the hot-pressing technology is used to manufacture a spool body, integrated strength is much higher than that of a stamping and welding spool, and manufacturing cost is much lower than thatof an integrated spool which is formed by forging and turning.

Description

technical field [0001] The invention relates to a package for winding ropes, silks, belts, wires, strips and other materials, in particular to a reinforced I-shaped wheel and a manufacturing method thereof. Background technique [0002] The I-shaped wheel is a tool used for winding metal wire or steel wire rope. According to the different materials and specifications of the wire rope to be wound, the specifications and materials of the I-shaped wheel are also different. The I-shaped wheel for winding steel wire generally uses a steel plate structure. [0003] Now conventionally used steel I-wheels are made of flanges, interlocking parts, welded on the cylinder and the shaft tube. On the surface of the cylinder where the wire rope is stored, flanges are connected at both ends; but the cylinder and the shaft are connected. The flange is a spliced ​​and welded structure, and there is a gap of more than 0.1-0.5mm. When the I-shaped wheel is used to wind extra-fine steel wires, s...

AI Technical Summary

Problems solved by technology

However, with the wide and in-depth application of ultra-fine steel wire, there is a new technology that requires conductive treatment of the steel wire during the winding process, that is, the steel wire needs to be charged through the I-shaped wheel, and the surface of the conventional steel I-shaped wheel is sprayed with anti- The rust paint layer has a good insulation effect, which makes it unable to meet the new production process requirements
