Carbon steel wire drawing machine production process details
The production process of carbon steel wire drawing machine is a complex system engineering involving mechanical design, material science, precision machining, electrical control and assembly testing. Its core goal is to manufacture equipment that can efficiently and stably draw carbon steel wire rods to the target wire diameter. The main production process is as follows:
1. Design and Engineering Preparation
Requirement Analysis and Scheme Design:
Clarify customer requirements: target wire diameter range, production capacity, line speed, material specifications (such as medium and high carbon steel), degree of automation, special requirements (such as wet drawing/dry drawing).
Conduct mechanical design: determine overall layout, drawing passes, power configuration, transmission scheme (direct connection/gearbox), winding method (I-beam spool/active unwinding).
Conduct electrical and control system design: select motors (AC/DC/variable frequency), PLC, HMI, sensors, frequency converters, lubrication and cooling system control, etc.
Design key components: drawing die box structure (cooling/lubrication channels), spool structure (material, cooling, surface treatment), tension control system, die changing mechanism, etc.
Complete engineering drawings (assembly drawings, sub-assembly drawings, part drawings), BOM list and technical specification sheet.
2.Machining and Manufacturing
Machining:
Large Structural Components Machining: Large milling machines, planers, and boring machines are used to process the frame base, wall plates, etc., ensuring the flatness, parallelism, and accuracy of installation holes, laying the foundation for the stability of the entire machine.
Key Rotating Components Machining:
Main Shaft/Drum: This is the core. It undergoes rough turning, fine turning, and grinding (outer diameter/inner hole) to ensure extremely high dimensional accuracy (especially at the bearing fit) and positional tolerances (roundness, cylindricity, coaxiality). The surface of the drum usually requires high-frequency quenching or carburizing quenching treatment, followed by fine grinding to the required hardness and surface roughness.
Drive Shaft: Turning, grinding, and keyway milling are carried out to ensure dimensional accuracy, coaxiality, and strength. Quenching and tempering treatment is required.
Gears: Hobbing/plug cutting, shaving/grinding (high-precision requirements), and surface quenching treatment of the tooth surface.
Mold Box/Guide Wheel Seat: Precision milling, drilling, and boring to ensure the precise position and perpendicularity/parallelism of the mold installation holes and guide wheel shaft holes.
Machining of Other Components: Turning, milling, drilling, and grinding of various brackets, flanges, couplings, guide wheels, tension arm parts, etc.
Heat Treatment:
Heat treatment of key wear-resistant and load-bearing parts to improve performance:
Drum, guide wheels, mold seats: Surface quenching (induction quenching) or overall quenching + tempering to achieve high hardness and wear resistance while maintaining core toughness.
Shafts, gears: Quenching and tempering (quenching + high-temperature tempering) to obtain good comprehensive mechanical properties (strength, toughness, fatigue resistance).
Some parts may require chemical heat treatments such as carburizing, nitriding, or carbo-nitriding.
Welding (if necessary):
Welding of large structural components such as frames and protective covers. Welding deformation must be strictly controlled, and annealing may be required to relieve stress when necessary.
4. Surface Treatment
Anti-rust and Decoration:
The machined parts undergo processes such as degreasing, rust removal, phosphating/bronzing.
