Product Description
In the process of chemical self-hardening sand casting, the hardened and solidified sand mold is carried, turned over, and the upper and lower sand molds are assembled together.
The manipulator is a kind of fully automatic modeling auxiliary equipment. Because of its high degree of automation, precise action and reliable performance, it improves the stability and practicability of the entire modeling line. It is mainly used for mold-drawing and box-turning and box-closing of molds in the final stage of modeling. It is suitable for automated production lines and production lines with high modeling accuracy. The parameters of the manipulator are determined non-standard according to the user's productivity and the size of the flask to achieve customized production.
In the chemical self-hardening sand casting process, the hardening, flipping and closing accuracy of the sand mold directly determines the casting yield and production efficiency. With the upgrading of the foundry industry's demand for automation and intelligence, the fully automatic manipulator is becoming the core equipment for modern foundry workshops to achieve "unmanned production" with its high-precision motion control and flexible customization capabilities. This article will deeply analyze how the manipulator enables the intelligent upgrade of the self-hardening sand casting process from the dimensions of technical adaptability, process innovation, customized design and benefit analysis.
1. Process adaptability and core functions
Chemical self-hardening sand casting requires that the sand mold has high strength (compressive strength ≥1.5MPa) and low deformation rate (dimensional tolerance ±0.3mm) after curing. The fully automatic manipulator meets the process requirements through the following functional modules:
Sand mold grabbing and transportation:
Vacuum adsorption system: It adopts a multi-chamber vacuum suction cup (suction range 0.6-1.2MPa), which is suitable for sand molds of different sizes (maximum grab weight 5 tons), and realizes non-destructive grabbing of sand molds through air pressure closed-loop control.
Path planning algorithm: Based on PID motion controller (repeat positioning accuracy ±0.1mm), it can accurately avoid obstacles on the production line and complete the seamless transfer of sand molds from the molding station to the pouring line.
Sand mold flipping and box closing:
Dual-station collaborative operation: The manipulator is equipped with a 360° rotating joint and torque sensor to achieve synchronous flipping and alignment of the upper/lower sand box (angle error <0.5°), solving the problem of misalignment rate of traditional manual box closing (box closing gap ≤0.2mm).
Visual correction system: Integrated laser profiler and CCD camera, real-time detection of sand mold parting surface flatness (accuracy 0.02mm), automatic compensation of box closing deviation, to ensure the sealing of the casting mold.
2. Technological innovation and customized design
For the complex working conditions of self-hardening sand casting, the manipulator achieves a breakthrough in process adaptability through modular architecture and intelligent sensing technology:
Flexible actuator:
Multi-axis linkage design: Adopts a 6-DOF manipulator (maximum arm span 4.5m), supports the composite actions of sand mold grabbing, flipping, and closing, and the operating range covers the sand box size of 0.5-3.5 meters.
Quick-change fixture system: Provides a variety of end effectors such as electromagnetic grippers and pneumatic grippers to adapt to the physical properties of different molding sands such as resin sand and water glass sand (such as surface roughness and air permeability).
Intelligent control technology:
Digital twin simulation: Preview the manipulator's motion trajectory through the virtual debugging platform, optimize the beat time (single closing cycle ≤60 seconds), and reduce the on-site debugging time by 40%.
Fault prediction system: Built-in vibration sensor and temperature monitoring module, real-time analysis of the health status of the reducer and servo motor, early warning of key component failures (MTBF≥10,000 hours).
3. Production scenarios and efficiency improvement
Typical application scenarios of manipulators in self-hardening sand casting lines include:
High-precision molding line integration:
Linked with the vibrating sand-dropping machine, the automatic unpacking of the sand box after pouring and the recycling of old sand are realized, and the single-line production capacity is increased to 40 boxes/hour.
Complex casting production:
Aerospace field: Through the collaborative operation of multiple manipulators (such as synchronous box closing of two machines), the zero-defect assembly of precision castings such as turbine blades (wall thickness ≤ 2mm) is completed.
Automotive parts field: Adapt to medium and large castings such as differential housings and cylinder blocks (weight 1-3 tons), and the box closing qualification rate is increased from 92% to 99.5%
