DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0019] The present application provides a method for manufacturing a wire feeding hose 4, and the method for manufacturing a wire feeding hose 4 comprises: Step 1, hot air drying the thermoplastic elastomer TPE raw material, the drying temperature is 100-110° C., and the drying time is 3-5 hours; Thermoplastic elastomer TPE raw materials produce byproduct water during the manufacturing process. Hot air drying can effectively remove this residual moisture and prevent defects such as bubbles and air marks in the thermoplastic elastomer TPE during processing. The dried thermoplastic elastomer TPE raw materials have better fluidity and plasticity, which helps to improve the processing efficiency and product quality of the wire feeding hose 4.

[0020] Step 2, heating and melting the dried thermoplastic elastomer TPE raw material at a heating temperature of 140-150° C.; Step 3, the molten thermoplastic elastomer TPE is extruded into a wire feeding hose 4 through an extruder, the extrusion temperature is 140-180° C., and the extruder includes three different temperature zones from the feed port to the extrusion port: a first temperature zone with a temperature range of 140-153° C., a second temperature zone with a temperature range of 153-167° C., and a third temperature zone with a temperature range of 167-180° C.; The first temperature zone is located near the feed port of the extruder, which is also the feeding section or feed section. It is mainly responsible for the preheating and initial softening of the raw materials. Since the raw materials have just entered the extruder from room temperature, a certain amount of heat is required to soften them and prepare for the next stage of plasticization. The temperature of the first temperature zone is set between 140 and 153 ° C. This temperature range can ensure that the raw materials are evenly heated and gradually softened, without causing degradation or burning of the raw materials due to excessive temperature.

[0021] The second temperature zone is located in the middle part of the extruder, which is the junction of the compression section and the melting section. It is used to further heat and plasticize the raw materials. Based on the initial softening in the first temperature zone, the second temperature zone requires a higher temperature to completely melt the raw materials and reach a plasticized state. The temperature of the second temperature zone is set between 153 and 167 ° C. This temperature range can ensure that the raw materials are completely melted and reach an ideal plasticized state, while avoiding degradation problems caused by overheating.

[0022] The third temperature zone is located near the exit of the extruder, that is, the metering section, die head and die part, which is used to ensure that the raw materials maintain an appropriate temperature during the extrusion process to prevent problems such as increased raw material viscosity, increased die head pressure or rough product surface caused by temperature reduction. At the same time, the third temperature zone is also responsible for evenly extruding the molten raw materials. The temperature of the third temperature zone is set between 167 and 180 ° C. This temperature range can ensure that the raw materials maintain sufficient heat and fluidity during the extrusion process, so as to obtain good quality extruded products.

[0023] Step 4, cooling and solidifying the extruded wire feeding hose 4, the cooling temperature is 40°C-50°C, after the wire feeding hose 4 is solidified, the hardness range of the wire feeding hose 4 is 57-61 degrees Shore.

[0024] The cooling temperature has an important influence on the physical properties of TPE. TPE solidified at a lower cooling temperature has higher hardness and strength, but TPE solidified at a higher cooling temperature has better flexibility and elasticity. The present application sets the cooling temperature to 40°C~50°C, so that the wire feeding hose 4 has a certain hardness to guide the welding wire; has good flexibility to adapt to the range of motion of the welding robot; and can withstand large bends without permanent deformation.

[0025] The present application adopts thermoplastic elastomer TPE to manufacture the wire feeding hose 4. Thermoplastic elastomer TPE is a polymer material that has the characteristics of both rubber and plastic. It exhibits rubber-like elasticity at room temperature, and has plasticity and can be formed at high temperature. The basic structural feature of the thermoplastic elastomer TPE polymer chain is that certain plastic segments (hard segments) and rubber segments (soft segments) with different chemical compositions are connected in series or grafted at the same time. The present application adjusts the ratio of the thermoplastic elastomer TPE hard segment and the soft segment to control the hardness range of the wire feeding hose 4 to 57-61 degrees Shore A, so that the wire feeding hose 4 has a certain hardness to guide the welding wire; has good flexibility to adapt to the movement range of the welding robot; can withstand large bending without permanent deformation.

[0026] Specifically, in step 1, the manufacturing method of the wire feeding hose 4 also includes a manufacturing method of a thermoplastic elastomer TPE raw material, and the manufacturing method of the thermoplastic elastomer TPE raw material includes: Step 101, copolymerizing 1,4-butylene phthalate and polybutanol under vacuum conditions to produce a thermoplastic elastomer TPE raw material, the reaction temperature is 200-230° C., the mass component ratio of 1,4-butylene phthalate and polybutanol is 68:22-72:28, and the reaction equation is: .

[0027] More specifically, the manufacturing method of the wire feeding hose 4 also includes: during the cooling and solidification process of the extruded wire feeding hose 4, a polyester fiber mesh is coated on the surface of the wire feeding hose 4, at which time the surface temperature of the wire feeding hose 4 is 115~125℃, and the surface of the wire feeding hose 4 is in a semi-molten state.

[0028] The polyester fiber mesh is woven from high-strength, high-modulus, low-creep polyester industrial filaments in the warp and weft directions, and has high tensile strength and node strength. The high-strength characteristics of the polyester fiber mesh can significantly improve the load-bearing capacity of the wire feeding hose 4, making it more durable; and the wire feeding hose 4 has a certain tensile strength, and is not stretched as much as possible when pushing the welding wire or being stressed. In addition, the polyester fiber mesh has a certain flexibility, which can make the wire feeding hose 4 have good bending performance while maintaining strength. In addition, the flame retardant and antistatic properties of the polyester fiber mesh can improve the safety of the wire feeding hose 4 and reduce the risk of fire and static hazards.

[0029] More specifically, the manufacturing method of the thermoplastic elastomer TPE raw material also includes: after copolymerization for 5 to 6 hours under vacuum and reaction temperature of 200 to 230°C, nitrogen is passed to normal pressure, antioxidant and anti-aging agent are added, the reaction is continued for 1.8 to 2.2 hours, the reaction product is transferred to a cooling kettle, cooled to 90 to 110°C and then pelletized. In the present application, the mass component ratio of 1,4-butylene phthalate, polybutanol, antioxidant and anti-aging agent is: 68 to 72:22 to 28:1:0.5.

[0030] After the copolymerization reaction is completed, the reaction system is restored to normal pressure by introducing nitrogen. Nitrogen is an inert gas that can prevent the oxygen in the air from reacting unnecessarily with the reaction products, thereby protecting the reaction products. After nitrogen purging, antioxidants and anti-aging agents are added to the reaction system. These additives can significantly improve the thermal stability, oxidation resistance and weather resistance of the polymer, thereby extending the service life of the polymer. After adding the additives, the reaction is continued for 1.8 to 2.2 hours. This stage is mainly to allow the additives to be fully dispersed in the polymer and interact with it to achieve the best modification effect.

[0031] The present application also provides a wire feeding hose 4, which is manufactured by the manufacturing method of the wire feeding hose 4. The wire feeding hose 4 manufactured by the above method has a certain hardness to guide the welding wire; has good flexibility to adapt to the movement range of the welding robot; and can withstand large bending without permanent deformation.

[0032] like Figure 1As shown, the present application also provides a welding robot cable, which includes: a wire feeding hose 4, an inert gas tube 5, at least one current conductor wire 1, at least one network cable 6, at least one shielded communication wire, at least one power line 9 and an outer sheath 10. The wire feeding hose 4, the inert gas tube 5, at least one current conductor wire 1, at least one network cable 6, at least one shielded communication wire, and at least one power line 9 are all located in the outer sheath 10. Among them, the wire feeding hose 4, the inert gas tube 5, at least one current conductor wire 1, at least one network cable 6, at least one shielded communication wire, and at least one power line 9 are respectively covered with an insulating layer 2. The gap between the outer sheath 10 and the wire feeding hose 4, the inert gas tube 5, at least one current conductor wire 1, at least one network cable 6, at least one shielded communication wire, and at least one power line 9 is filled with a tensile aramid fiber 3 filling layer.

[0033] The wire feeding hose 4 is used for feeding the welding wire. The inert gas tube 5 is used to transport inert gas, such as argon, helium, etc., which is mainly used as a shielding gas during the welding process. They have stability and low reactivity, can effectively isolate the surrounding air, and prevent the metal material from reacting with oxygen in the air during the welding process, thereby avoiding adverse reactions such as oxidation and nitridation, and ensuring the welding quality. In addition, the inert gas can also provide a stable arc environment, which is conducive to the formation and beauty of the weld. The current conductor line 1 is used to transmit the welding current, and the current generated by the welding power supply is safely and stably transmitted to the welding part to achieve the melting and connection of the metal. The network cable 6 is used to transmit the welding robot command signal. The shielded communication line is used to control the action of the welding robot. The power cord 9 is used to provide the welding robot with power supply / welding power supply.

[0034] The welding robot cable can not only adapt to the movement range of the welding robot, but also play a role in guiding the welding wire.

[0035] The gaps in the welding robot cable are filled with tensile-resistant aramid fiber 3, which makes the welding robot cable more flexible than traditional mesh belt filling, and the welding robot cable also maintains high tensile resistance. The tensile-resistant aramid fiber 3 can be well filled in the gaps between the wires, which can ensure that there is no shaking and friction between the wires to generate heat energy, and can also keep the welding robot cable round and tight, which can improve the torsion resistance of the welding robot cable and extend the service life of the welding robot cable.

[0036] Specifically, the inert gas tube 5, at least one current conductor line 1, at least one network cable 6, at least one shielded communication line, and the power line 9 are spirally wound around the outer periphery of the wire feeding hose 4. By arranging the wire feeding hose 4 in the middle, the wire feeding hose 4 is used as the central cable of the welding robot cable, so that the hardness of the welding robot cable is close to the hardness of the wire feeding hose 4, and then the welding robot cable has a certain hardness and good flexibility, which can not only adapt to the movement range of the welding robot, but also play a guiding role for the welding wire.

[0037] Specifically, the current conductor line 1 includes a first current conductor line 1 and a second current conductor line 1 .

[0038] The network cable 6 adopts Category 6A network cable 6. The signal transmission frequency of Category 6A network cable 6 can reach 500mhz, supporting 10G network speed. The use of Category 6A network cable 6 has the advantages of small attenuation and small crosstalk, which can improve the delay error. In this way, when inputting instructions, the welding robot can quickly and accurately receive instructions and perform operations.

[0039] The shielded communication line includes a first shielded communication line 7 and a second shielded communication line 8, which can respectively control different actions of the welding robot to make the welding robot more intelligent.

[0040] The power cord 9 includes a power supply cord 9, a first welding power cord 9 and a second welding power cord 9, which serves as a dedicated line to prevent the welding robot from stopping working due to insufficient power supply, and avoids heating of the welding robot due to unstable voltage, thereby preventing safety hazards.

[0041] The present application also provides a method for manufacturing a welding robot cable, the method for manufacturing a welding robot cable comprising: The wire feeding hose 4 is manufactured by adopting the above-mentioned manufacturing method of the wire feeding hose 4; The elastic polyvinyl chloride flexible insulation material is extruded into a tube by a rubber extruder, and the cotton thread is woven on the outer surface of the tubular elastic polyvinyl chloride flexible insulation material by a braiding machine, and the elastic polyvinyl chloride flexible insulation layer 2 is extruded outside the cotton thread braiding layer to form an inert gas tube 5; A current conductor is formed by twisting a plurality of oxygen-free copper wires, an insulating non-woven wiring tape is wound around the outer surface of the current conductor, and an elastic polyvinyl chloride flexible insulating layer 2 is extruded on the insulating non-woven wiring tape to form a current conductor line 1; A shielded communication line conductor is formed by twisting multiple strands of toughened fine tinned soft copper wires, and an elastic polyvinyl chloride flexible insulation material is extruded on the shielded communication line conductor to form a shielded communication line conductor wire, and several shielded communication line conductor wires are twisted into a shielded communication line core, and an insulating non-woven wiring tape is wrapped around the shielded communication line core, and then an elastic polyvinyl chloride flexible insulation material sheath is extruded outside the insulating non-woven wiring tape to form a shielded communication line; The power cord 9 is formed by twisting a plurality of oxygen-free copper wires, an insulating non-woven wiring tape is wrapped around the outer surface of the power cord 9, and an elastic polyvinyl chloride flexible insulation layer 2 is extruded on the insulating non-woven wiring tape to form the power cord 9; The inert gas tube 5, at least one current conductor wire 1, at least one network cable 6, at least one shielded communication wire, and at least one power line 9 are spirally wound around the outer periphery of the wire feeding hose 4 to form a bus bundle; The outer surface of the bus bundle is wound with tensile aramid 3, an insulating non-woven wiring tape is wound on the tensile aramid 3, and a modified polyvinyl chloride-nitrile mixed flexible insulating material outer sheath 10 is extruded on the insulating non-woven wiring tape to form a welding robot cable.

[0042] The outer sheath 10 is made of a modified polyvinyl chloride-nitrile mixed material, which can maintain the softness of the cable and has good wear resistance, as well as oil resistance and corrosion resistance. Therefore, the welding robot cable is suitable for installation in dry or humid indoors, in free continuous reciprocating motion without strong stress relief or forced guidance, and in frequent bending occasions in industrial use environments.
