Description

Heat treatment apparatus with easy mesh belt alignment The present invention relates to a heat treatment device that facilitates mesh belt alignment, and more specifically, to a heat treatment device that facilitates mesh belt alignment by continuously aligning the mesh belt so that the mesh belt does not deviate from the track. Generally, a mesh belt conveyor is a conveyor connected by a metal belt having multiple through holes between a pair of sprockets, and most mesh belt conveyors are installed to pass inside a high-temperature heating furnace. Heat treatment refers to the process of heating or cooling metals or machine parts to alter their properties and achieve the required strength. This process typically consists of a heat treatment furnace and a cooling device, and a mesh belt conveyor is used as a means to transport metal materials or machine parts into the furnace and cooling device. FIG. 1 is a perspective view illustrating a mesh belt for heat treatment according to the prior art, and FIG. 2 is a partial enlarged view illustrating a side portion of a mesh belt for heat treatment according to the prior art. Referring to Fig. 1, the mesh belt has a simple mesh shape and undergoes thermal expansion due to the characteristics of the metal material as it continuously passes through the inside of a high-temperature heating furnace. The material of such a mesh belt is typically a nickel and chromium alloy steel, and its heat resistance is approximately 1000°C to 1100°C. However, as the mesh belt described above simply has a mesh shape in which ring chains (200) are interwoven, frequent friction occurs with the heating device installed inside the heat treatment furnace while it is being transported into the heat treatment furnace, and the mesh belt itself frequently fails to withstand the heat and is damaged. As can be seen by referring to FIGS. 1 and 2, the mesh belt of the prior art is formed in the shape of a mesh belt by having a plurality of support pins (100) arranged at regular intervals and ring chains (200) connected between the support pins (100). At this time, the leftover portions at the side ends of the support pin (100) and the ring chain (200) are bent to be connected to each other, and the side portions of the mesh belt are fixed by partial welding of the connected portions. However, there is a problem in that the joint force weakens and the welded portion where the support pin (100) and the ring chain (200) are bent and connected to each other weakens as they repeatedly pass through the inside of a high-temperature heating furnace, and the shape of the mesh belt easily deforms as the welded portion becomes soft. As a result, the deformed mesh belt does not allow for smooth orbital movement by the drive roller, and there is a problem in that the deformed part may get caught in the drive roller, causing the mesh belt to break or the conveyor to stop operating, thereby halting work. Meanwhile, mesh belts that continuously move in orbit have a force that tends to change their trajectory due to the conveying speed and applied load, so it is necessary to limit and guide this. FIG. 1 is a perspective view illustrating a mesh belt for heat treatment according to the prior art. FIG. 2 is a partial enlarged view illustrating a side view of a mesh belt for heat treatment according to the prior art. FIG. 3 is a perspective view illustrating a mesh belt assembly and a guide roller assembly according to one embodiment of a heat treatment device that facilitates mesh belt alignment according to the present invention, and shows the shape when the mesh belt assembly passes under the heating furnace in an endless track trajectory.
