Cutting by a bucket tooth processing sawing machine
The following are the technical key points and industry application standards of sawing machine cutting in bucket tooth processing, compiled based on current manufacturing standards and practical experience:
I. Sawing Machine Equipment Selection and Technical Characteristics
Vertical band saw machine
It adopts a circular saw band for vertical cutting and is equipped with a servo control system to achieve ±0.02mm stroke positioning accuracy. The clamping force is ≥5 tons to prevent cutting vibration.
Technological upgrade in 2025: The modular fixed mechanism is compatible with billets ranging from φ50 to 200mm, and the sawing height is expanded to 100-800mm.
Metal band saw machine classification
Horizontal : The hydraulic double-column structure ensures smooth cutting and supports 90°/45° Angle cutting (for example, the maximum sawing size of the GB42320 model is 3.2m×3.2m).
Vertical : Optimized chip removal design, with the electric slider driving the cleaning brush to automatically clean the waste chips, improving the continuous operation efficiency.
Ii. Core Cutting Process Parameters
Parameters: high-strength steel (Q500MC) weathering steel (Q295NH) control objective:
Linear velocity 25-40m/min - to prevent material hardening
Coolant flow rate ≥15L/min - suppress the heat-affected zone
The cross-sectional roughness -Ra ≤12.5μm is achieved by laser compound cutting
Length tolerance ≤±0.5mm ≤±0.5mm ensures forging reference
Tool selection : tungsten-cobalt cemented carbide saw teeth (YG8), rake Angle γ=10° to 15°, bending strength ≥3500MPa, saw tooth thickness 1.0-1.2mm.
Iii. Process Connection and Quality Control
Pretreatment requirements
Blunting of edges and corners: The R Angle of the cutting surface should be ≥0.5mm to eliminate the risk of forging stress concentration.
Billet grouping: The weight difference within the same batch is ≤±0.5% to ensure uniform filling in die forging.
Defect detection
Magnetic particle testing is used to inspect cross-sectional cracks (with a sensitivity of ≥0.1mm) and remove internal defects.
The forging process should be transferred within 24 hours after cutting to prevent the thickening of the oxide layer from affecting the quality of the forging.
Iv. Reference for Material Processing Costs
Material type process unit price range applicable scenarios
Q500MC high-strength steel sawing machine cutting + cooling oil ¥4800 per ton excavator bucket tooth base material
Q295NH weathering steel laser composite sawing ¥4,650-4,768 per ton for corrosion-resistant parts of construction machinery
Operating safety specifications :
Before starting, verify the tension of the saw band and the accuracy of the guiding device. The verticality error of the workpiece clamping should be less than 0.5°.
The recommended cutting speed for cast iron parts is 25-35m/min. Hard alloys need to be replaced regularly to prevent breakage.
