Description

Technical Field

[0001] The utility model belongs to the technical field of steel wire preheating, and in particular relates to a steel wire preheating device. Background Art

[0002] Steel wire is one of the four major varieties of steel: plate, tube, profile and wire. It is a reprocessed product made of hot-rolled wire rod by cold drawing. Heater is a modern word and a proper noun. It refers to a glass fiber reinforced refractory fiber layer wrapped around the multi-strand resistance wire strands, and a metal wire reinforced refractory fiber layer woven outside the refractory fiber layer. The double-layer coating layer tightly combined and distributed along the entire length of the resistance wire strands and the resistance wire strands at its center form an integral direct heating monomer that can be bent as needed and can be in close contact with the heated part. The core of the heater principle is energy conversion. The most widespread is the conversion of electrical energy into thermal energy. In addition, there are energy conversion modes such as nuclear energy and wind energy, but they generally need to be converted into electrical energy for use. In steel wire production, heating devices are often used to heat the steel wire to make it more convenient to shape the steel wire.

The utility model discloses an energy-saving preheating device for steel wire production. By setting a fixing block, a threaded rod, a push plate and a clamping plate, the steel wire can be fixed very conveniently and effectively, thereby saving staff time and improving production efficiency. However, the clamping structure is relatively simple, and unstable clamping may cause the position of the steel wire to move during the preheating process, thereby affecting the heat treatment effect of the steel wire and making it impossible to guarantee the quality of the final product. Therefore, it is necessary to provide a steel wire preheating device to solve the above problems. Utility Model Content

The design of the serrated structure can avoid scratches or damage to the surface of the steel wire. During the clamping process, the serrated structure can produce relative sliding with the steel wire, thereby reducing friction and wear on the surface of the steel wire.
