preparation example Construction

[0013] The invention provides a preparation method of a corrosion-resistant mechanical arm. The preparation method comprises:

[0014] 1) Mix ductile iron, silicon carbide particles, graphite fibers, manganese, nickel, chromium, ceria and vanadium pentoxide, and then conduct the first smelting to obtain molten iron M1;

[0015] 2) adding manganese trioxide, pentlandite, boron nitride, molybdenum sulfide, carbon black and niobium into the molten iron M1, followed by a second smelting to obtain the molten iron M2;

[0016] 3) Casting the molten iron M2 to obtain a parison, and performing heat treatment on the parison to obtain the corrosion-resistant mechanical arm.

[0017] In the above technical solution, the specific amount of each raw material used can be selected within a wide range, but in order to further improve the strength and anti-electromagnetic interference performance of the manufactured mechanical arm, preferably, in parts by weight, the The dosage ratio of ducti...

Embodiment 1

[0026] 1) After mixing ductile iron, silicon carbide particles, graphite fibers, manganese, nickel, chromium, ceria and vanadium pentoxide, smelting at 1700°C for 4 hours to obtain molten iron M1;

[0027] 2) Dimanganese trioxide (average particle size 20 μm), pentlandite (average particle size 25 μm), boron nitride (average particle size 30 μm), molybdenum sulfide (average particle size 20 μm), carbon black (the average particle size is 30 μm) and niobium are added to the molten iron M1, followed by smelting at 1500° C. for 2 hours to obtain the molten iron M2;

[0028] 3) Casting the molten iron M2 to obtain a parison (the temperature of the parison is 750°C), and keeping the parison at 800°C for 2 hours, then cooling down to 600°C at a rate of 10°C / min for 5 hours, The most direct water cooling after heat preservation is to obtain the corrosion-resistant mechanical arm, denoted as A1.

[0029] Wherein, in parts by weight, the ductile iron, silicon carbide particles, graphi...

Embodiment 2

[0031] 1) After mixing ductile iron, silicon carbide particles, graphite fibers, manganese, nickel, chromium, ceria and vanadium pentoxide, smelting at 1750°C for 3 hours to obtain molten iron M1;

[0032] 2) Dimanganese trioxide (average particle size 25 μm), pentlandite (average particle size 25 μm), boron nitride (average particle size 30 μm), molybdenum sulfide (average particle size 20 μm), carbon black (the average particle size is 30 μm) and niobium are added to the molten iron M1, followed by smelting at 1550° C. for 2 hours to obtain the molten iron M2;

[0033] 3) Cast the molten iron M2 to obtain a parison (the temperature of the parison is 800°C), and keep the parison at 850°C for 1 hour, then cool it down to 500-600°C at a rate of 15°C / min and keep it warm 3-5h, the most direct water cooling after heat preservation, that is, the corrosion-resistant mechanical arm is produced, which is recorded as A2.

Abstract

The invention discloses a corrosion-resistant manipulator and a preparation method thereof. 1) firstly mix nodular cast iron, silicon carbide particles, graphite fibers, manganese, nickel, chromium, ceria and vanadium pentoxide and then carry out the first smelting to obtain Molten iron M1; 2) adding manganese trioxide, pentlandite, boron nitride, molybdenum sulfide, carbon black and niobium into the molten iron M1, followed by a second smelting to obtain molten iron M2; 3) adding the The molten iron M2 is casted to obtain a parison, and the parison is heat-treated to obtain the corrosion-resistant mechanical arm. The excellent corrosion resistance of the robotic arm enables it to be exposed to the production workshop for a long time, which ensures the progress of production, reduces the maintenance probability of the robotic arm, and greatly improves the service life of the robotic arm working in the workshop.

Description

technical field [0001] The invention relates to the field of industrial assembly, in particular to a corrosion-resistant mechanical arm and a preparation method thereof. Background technique [0002] The robotic arm is a high-precision, high-speed dispensing robotic arm. The robotic arm is a complex system with multiple inputs and multiple outputs, highly nonlinear, and strong coupling. Because of its unique operational flexibility, it has been widely used in industrial assembly, safety explosion-proof and other fields. [0003] The industrial robotic arm is a mechatronic device that anthropomorphizes the functions of the arm, wrist and hand. A mechatronic device that anthropomorphizes the functions of the human arm, wrist and hand; it can move any object or tool according to the time-varying requirements of the spatial posture (position and attitude), so as to complete the operation requirements of an industrial production. Such as clamping welding tongs or welding torche...
