Abstract
The invention discloses a whole casting molding process of a polyurethane robot track, and relates to a robot track molding process. A main material selected by the method is a high-performance casting polyurethane elastomer material; high-strength and high-modulus aramid fibers are used as a reinforced skeleton layer; a structure mode of a whole ropy winding annular belt is used for combining and simplifying a core gold block, a cladding layer, a buffer layer and a pattern block in a rubber track to the same polyurethane elastometer material; core gold is directly engaged with track wheels; the shape is totally depended on the structure and the size of synchronous teeth of the track wheels; and a covering layer and a pattern rubber block are both positioned on the outermost layer of the track. The process is simple, and is fast in molding; and the prepared polyurethane robot track has such characteristics as light mass, high strength, simple structure, simple process, quick molding and stable quality.
Description
Technical field
The present invention relates to a kind of robot crawler belt moulding technique, particularly relate to a kind of polyurethane robot crawler belt integral pouring forming technology method.
Background technology
Robotics has progressively developed into application branch of learning economy and social development to material impact since being born from the sixties in last century from the checking experimental system mainly as artificial intelligence study.Except industrial circle, robot is accelerating to national security field, major scientific projects field and community service field development.This kind of robot is usually structural environment in workshop unlike industrial robot, in fixed position operation, but is in non-structure environment or wild environment, based on mobile operating, defines robot system miscellaneous.
No matter be explore on celestial body surface, go deep into earthquake or the scene of the accident disaster relief, or want smoothly by high aloft electric wire with cross electric pole and face complexity, the unknown, changeable non-structure environment, present mobile robot has a wide range of applications in each field.Comprise fight against terrorism and violence, emergency management and rescue, polar region detection, electric power facility detection and maintenance and nuclear radiation detection etc., mobile robot often will work in various complexity, extreme environment (high/low temperature, super-pressure, nuclear radiation etc.), various landform (soft or hard ground, beach, meadow, trench etc.), having good adaptability, flexibility, is necessary guarantee to overcome the walking mechanism of the instable robot of environment.
Crawler belt is as an important main ground-engaging element of robot, and the quality of its performance has vital impact to mobile robot.Material, the structure of crawler belt and forming method all decides crawler belt and whether mobile robot can adapt to the extreme environment of various complexity.The kind of current crawler belt mainly comprises metal track and rubber belt track.The shortcoming that metal track is huge because it is heavy, generally seldom uses mobile robot.Rubber belt track is the endless rubber belt that rubber and metal or fibrous material are composited, and generally comprises core gold, strength layer, cushion, clad and decorative pattern blob of viscose composition.Rubber belt track has that ground pressure is little, tractive force is large, it is little to shake, noise is low, good by property, do not damage by face, travel speed fast, the advantages such as quality is low, but rubber belt track also also exists complex process, make loaded down with trivial details, the shortcoming of constant product quality difference.
Summary of the invention
The object of the present invention is to provide a kind of polyurethane robot crawler belt integral pouring forming technology method, present invention process is simple, fast shaping, and the polyurethane robot crawler belt of preparation has the features such as light weight is high-strength, structural reduction, technique are simple, shaping fast, steady quality.
The object of the invention is to be achieved through the following technical solutions:
A kind of polyurethane robot crawler belt integral pouring forming technology method, material of main part selected by described method is high performance casting type polyurethane elastomer material, adopt the aramid fiber of high-strength, high-modulus as powerful casing play, use whole-root rope shape to be wound around the frame mode of endless belt, by rubber belt track core gold bullion, clad, cushion and pattern block merge simplification and become polyurethane elastomer material of the same race; Core gold directly engages with Athey wheel, and shape depends on structure and the size of Athey wheel synchronous gear completely; Cover layer and decorative pattern blob of viscose are all the outermost layers occuping crawler belt, Integratively pouring forming technology will for forming temperature, briquetting pressure, with the impact of molding time for moulded products dimensional stability and mechanical performance, employing factor-function variable method returns pursues optimum process conditions.
Advantage of the present invention and effect are:
1. fast shaping, simplify production technology, save more time and a large amount of equipment investments;
2. the intensity between strength layer and adhesion have been increased substantially;
3. reduce crawler belt sectional dimension, reduce crawler belt weight.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
Embodiment 1:
(1) aramid fiber is arranged in mould with single rope winding 8 delineation;
(2) Integrativelies such as base polyurethane prepolymer for use as, chain extender and other auxiliary agents are poured in the mould of positioning winding aramid fiber rope;
(3) forming temperature is set to 100 ° of C, briquetting pressures and is set to 20MPa;
(4), after shaping 30min, goods are taken out.
Embodiment 2:
(1) aramid fiber is arranged in mould with single rope winding 10 delineation;
(2) Integrativelies such as base polyurethane prepolymer for use as, chain extender and other auxiliary agents are poured in the mould of positioning winding aramid fiber rope;
(3) forming temperature is set to 110 ° of C, briquetting pressures and is set to 20MPa;
(4), after shaping 25min, goods are taken out.
Embodiment 3:
(1) aramid fiber is arranged in mould with single rope winding 12 delineation;
(2) Integrativelies such as base polyurethane prepolymer for use as, chain extender and other auxiliary agents are poured in the mould of positioning winding aramid fiber rope;
(3) forming temperature is set to 120 ° of C, briquetting pressures and is set to 20MPa;
(4), after shaping 20min, goods are taken out.
Claims (1)
1. a polyurethane robot crawler belt integral pouring forming technology method, it is characterized in that, material of main part selected by described method is high performance casting type polyurethane elastomer material, adopt the aramid fiber of high-strength, high-modulus as powerful casing play, use whole-root rope shape to be wound around the frame mode of endless belt, by rubber belt track core gold bullion, clad, cushion and pattern block merge simplification and become polyurethane elastomer material of the same race; Core gold directly engages with Athey wheel, and shape depends on structure and the size of Athey wheel synchronous gear completely; Cover layer and decorative pattern blob of viscose are all the outermost layers occuping crawler belt, Integratively pouring forming technology will for forming temperature, briquetting pressure, with the impact of molding time for moulded products dimensional stability and mechanical performance, employing factor-function variable method returns pursues optimum process conditions.
