Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing, and in particular to a high-temperature resistant and pressure-resistant flat belt for wire traction machines. Background Technology

[0002] Large cross-section wire (10mm) 2 -105mm 2 During production and processing, the drive belts used in track traction are generally flat belts. During operation, the upper and lower flat belts need to be clamped together to move the wire forward horizontally. Due to the weight of large-section wires, to prevent slippage between the upper and lower flat belts of the traction machine, the clamping force applied to the belts is very large, which can easily cause the wire to flatten. Once the wire is flattened to a certain extent, its ellipticity will exceed the requirements, increasing the difficulty of wire splicing, reducing the reliability of the splice, and thus adversely affecting the wire's service life and reliability.

[0003] Large-section wires with fluoroplastic insulation (such as polytetrafluoroethylene film wrapping insulation) have a short distance from the high-temperature sintering furnace to the traction machine. After the large-section wires are cooled by air over this short distance, their surface temperature remains high.

[0004] Existing neoprene and polyurethane belts will age rapidly under prolonged exposure to such high temperatures, resulting in problems such as belt hardening, surface cracking, and surface pitting. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high-temperature resistant and anti-flattening belt for a wire pulling machine. It can withstand high temperatures, reduce the clamping force on large cross-section wires during operation, and make the clamping force distribution more uniform, thereby preventing the wires from being flattened. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant and pressure-resistant flat belt for an electric wire traction machine, comprising a large-section electric wire, an upper belt assembly, and a lower belt assembly. One end of the large-section electric wire is connected to a lead wire. An upper belt traction machine and a lower belt traction machine are respectively installed on the upper and lower sides of the large-section electric wire. The lower belt traction machine contains the lower belt assembly, and the upper belt traction machine contains the upper belt assembly. The upper belt assembly comprises an outer upper belt layer, an intermediate upper belt layer, and a bottom upper belt layer. The traction machine pulley in the upper belt traction machine contacts the bottom upper belt layer. An intermediate upper belt layer is installed on the outer side of the bottom upper belt layer, and an outer upper belt layer is installed on the outer side of the intermediate upper belt layer. The outer upper belt layer, the intermediate upper belt layer, and the bottom upper belt layer are tightly bonded together.

[0007] When producing large-section wires, lead wires are required. The outer diameter of the lead wires is generally much smaller than that of the large-section wires. The upper and lower belt assemblies are used to allow the lead wires to pass through for processing large-section wires. The outer layer of the upper belt is made of fluorosilicone rubber, the middle layer of the upper belt is made of silicone rubber, the thickness of the middle layer of the upper belt is 3-6mm, and the bottom layer of the upper belt is made of polyurethane for assembly.

[0008] Furthermore, the lower belt assembly includes an outer lower belt layer, a middle lower belt layer, and a bottom lower belt layer. The traction pulley in the lower belt traction machine contacts the bottom lower belt layer. The middle lower belt layer is disposed on the outer side of the bottom lower belt layer. The outer side of the middle lower belt layer is connected to the outer lower belt layer. The outer lower belt layer, the middle lower belt layer, and the bottom lower belt layer are tightly bonded together. A large cross-section wire passes through the lower belt assembly and the upper belt assembly.

[0009] The outer layer of the lower belt is made of fluorosilicone rubber, the middle layer of the lower belt is made of silicone rubber, the thickness of the middle layer of the lower belt is 3-6mm, and the bottom layer of the lower belt is made of polyurethane, for the assembly device.

The outer surfaces of the lower belt outer layer and the upper belt outer layer are provided with snap-fit ​​grooves, and each snap-fit ​​groove is provided with a flexible reinforcing rod. A high-temperature resistant layer and a flexible reinforcing mesh are respectively provided between the lower belt outer layer and the lower belt middle layer, and between the upper belt outer layer and the upper belt middle layer. The lower belt outer layer, the high-temperature resistant layer, the flexible reinforcing mesh, and the lower belt middle layer are tightly bonded together, and the upper belt outer layer, the high-temperature resistant layer, the flexible reinforcing mesh, and the upper belt middle layer are also tightly bonded together.

[0011] The flexible reinforcing rod is made of para-aramid material to enhance strength and facilitate reinforcement. The high-temperature resistant layer is made of flexible ceramic film to enhance strength and facilitate heat insulation protection. The flexible reinforcing mesh is made of flexible material with a mesh structure to enhance strength, extend the service life of the device, and facilitate use.

[0012] Furthermore, it also includes isosceles trapezoidal structures. The outer surfaces of the outer layers of the upper and lower belts are provided with 1-3 longitudinal isosceles trapezoidal structures. The isosceles trapezoidal structures on the outer layers of the upper belt are upright trapezoids, and the isosceles trapezoidal structures on the outer layers of the lower belt are inverted trapezoids. The isosceles trapezoidal structures on the outer layers of the upper and lower belts are completely fitted together.

[0013] The isosceles trapezoidal structure increases the contact surface with large-section wires, thereby making the clamping force distribution more uniform and reducing the clamping force, effectively preventing the wire from being flattened and improving the ellipticity performance of the wire.

[0014] Furthermore, it also includes a tensile core layer, wherein a tensile core layer is provided between the upper belt middle layer and the upper belt bottom layer on the upper belt assembly, and a tensile core layer is provided between the lower belt middle layer and the lower belt bottom layer on the lower belt assembly.

[0015] The tensile core layer is made of para-aramid material to enhance strength, prevent the belt from being flattened, and facilitate use.

[0016] Furthermore, it also includes a toothed structure, wherein the inner surfaces of the upper belt bottom layer and the lower belt bottom layer are respectively provided with toothed structures, and all the toothed structures match the tooth grooves of the pulleys in the corresponding upper belt traction machine and lower belt traction machine.

[0017] The convex tooth structure is used to facilitate matching with the corresponding traction machine pulley tooth groove, so as to facilitate quick installation and use.

[0019] This electric wire traction machine uses a high-temperature resistant and pressure-resistant flat belt, which has the following advantages:
