Description

Technical Field

[0001] This utility model relates to the field of conveyor chain production technology, specifically a heat treatment furnace for conveyor chain production. Background Technology

[0002] Like drive chains, precision conveyor chains consist of a series of bearings fixed by restraining chain plates, with highly precise positional relationships between them. Each bearing includes a pin and a sleeve upon which the chain rollers rotate. Both the pin and sleeve are surface-hardened, allowing them to hinge together under high pressure and withstand the load pressure transmitted through the rollers and the impact of meshing. Conveyor chains of varying strengths have a range of different chain pitches: the minimum chain pitch depends on the required strength of the sprocket teeth, while the maximum chain pitch is typically determined by the rigidity of the chain plates and the general-purpose chain. If necessary, the rated maximum chain pitch can be exceeded by reinforcing the sleeves between the chain plates, but clearance must be maintained in the sprocket teeth to clear the sleeves. Conveyor chains require heat treatment during production.

[0003] Utility model patent CN217578995U discloses a heat treatment furnace for the production of microcrystalline iron cores, relating to the field of heat treatment technology. Specifically, it is a heat treatment furnace body, with a mounting base fixedly installed at the bottom of the furnace body. Support frames are provided at both ends of the mounting base, and a conveyor chain plate is movably installed inside the support frames. A drive motor is fixedly installed on the front of the right side of the support frame. This heat treatment furnace for microcrystalline iron core production places the workpiece on top of a placement plate. The drive motor drives the conveyor chain plate and placement plate to move, causing the workpiece to move intermittently and transport it to different chambers inside the furnace body for processing. During workpiece movement, multi-stage hydraulic rods control the opening and closing of different high-temperature resistant central partitions and guide sliders, achieving uninterrupted processing of the workpiece and improving heat treatment efficiency.

[0004] Currently, the doors of heat treatment furnaces are designed to isolate the inside and outside of the furnace, and the closing effect of the doors is subject to very strict requirements. However, since some heat treatment furnace doors are opened and closed manually by workers, it is not only troublesome, but also prone to incomplete closure, which brings a lot of inconvenience to the heat treatment work. At the same time, a large amount of fumes are generated during heat treatment, and the fumes need to be moved to the purifier located at the top of the heat treatment furnace for treatment. The sludge accumulated inside the purifier after treatment has an adverse effect on the usable area of ​​the purifier. Utility Model Content
