In the process of agricultural modernization, the seed drill is a key equipment to improve agricultural production efficiency, and its performance directly affects the seeding quality and farmland operation efficiency. From metal raw materials to formed frames, laser pipe cutting machines, laser plate cutting machines, pipe bending machines and laser welding machines work together to create a solid frame that can adapt to harsh agricultural operations with exquisite craftsmanship.
1. Pipe cutting - Precision cutting of laser pipe cutting machines
The laser pipe cutting machine achieves high-precision cutting of pipes with high-energy-density laser beams, laying the foundation for the structural stability of the frame. The laser pipe cutting machine has the following advantages:
High-precision component adaptation: The cutting accuracy of the laser pipe cutting machine can reach ±0.1mm, which can ensure that the dimensional error of each pipe component of the frame is controlled within a very small range.
Special-shaped cutting meets complex structural design: The laser pipe cutting machine can accurately control the cutting path through the CNC system, and easily complete complex processing such as bevel cutting and waist-shaped hole cutting of pipes. For example, long circular holes are cut on the frame crossbeams for adjusting the seeding row spacing, which supports the versatility of the equipment.
2. Plate processing - Fine carving of laser plate cutting machine
The laser plate cutting machine uses a high-energy laser beam to accurately cut the steel plate to give the frame components precise shapes and sizes. Laser cutting machines have the following features:
High-quality cuts improve connection strength: The edges of steel plates cut by laser plate cutting machines are flat and burr-free, and the cuts are highly vertical and can be directly used for welding without secondary grinding.
Large-format cutting adapts to large-scale component processing: The work surface of the laser plate cutting machine can meet the processing needs of such large plates, and can complete the cutting of the entire plate at one time, reducing the splicing process and improving production efficiency.
Complex graphic cutting realizes functional integration: Cutting precise installation holes, weight-reducing holes and reinforcement rib contours on the steel plate is the strength of the laser plate cutting machine.
3. Pipe bending - shaping assistance of pipe bending machine
Some pipes of the planter frame (such as handrails, guardrails, and special-shaped support beams) need to be bent into specific angles and arcs to adapt to the convenience of human-machine operation and the overall structural layout of the equipment. The pipe bending machine applies external force to the pipe through the die, causing it to plastically deform and form the desired shape.
(I) Equipment function
Precise angle control ensures structural symmetry: The CNC system of the pipe bending machine can accurately control the bending angle with an error of ≤±0.5°, which can ensure that the bending angles of the symmetrical parts on both sides of the frame are consistent.
Anti-wrinkle bending ensures the strength of the pipe: The pipe bending machine driven by CNC servo, with anti-wrinkle die and pressure die, can apply uniform pressure to the inner and outer walls of the pipe during the bending process.
Multi-stage bending and one-time forming improves efficiency: The pipe bending machine can be controlled by program to achieve multi-angle and multi-radius bending in one clamping, reduce the number of clamping times, and improve processing efficiency and dimensional consistency.
(II) Operation process
Mold selection and installation: According to the pipe diameter and bending radius, select the appropriate bending mold, clamping mold and anti-wrinkle mold, install them to the corresponding position of the pipe bending machine and calibrate the central axis to ensure that they coincide with the pipe axis.
Pipe clamping and parameter setting: Insert one end of the steel pipe into the clamp of the pipe bending machine and clamp it.
Bending operation and real-time monitoring: Start the pipe bending machine, and the equipment completes the bending action according to the program. During the process, the bending angle is monitored in real time through the angle sensor, and it stops automatically when it reaches the preset value; the operator observes whether there are scratches or wrinkles on the surface of the pipe.
4. Component assembly and welding - Firm connection of laser welding machine
Laser welding machine uses high energy density laser beam to achieve precision welding between components, ensuring the overall strength and stability of the frame.
(I) Equipment advantages
Deep melting welding ensures connection strength: Laser welding machine can form deep and narrow welds with a melting depth of 3-10mm.
Low heat input reduces welding deformation: The heat-affected zone of the laser welding machine is small (usually ≤0.5mm).
Automated welding improves consistency: The laser welding machine equipped with a robot can realize the automated welding of complex welds, and adjust the welding path in real time through the visual tracking system to ensure the consistency of each weld, reduce human operation errors, and improve the stability of the frame welding quality.
From high-precision cutting to strong welding, laser pipe cutting machines, laser plate cutting machines, pipe bending machines, and laser welding machines work together to create a high-quality structure with strength, precision, and durability for the seed drill frame.
