Description

Technical Field

[0001] This utility model relates to the field of disassembly device technology, specifically to a device for disassembling a truncated cone spiral spring. Background Technology

[0002] In the field of non-ferrous metal smelting, truncated cone spiral springs are widely used in various smelting furnaces and kilns due to their unique shape and excellent mechanical properties. These springs offer high elasticity and restoring force while occupying minimal space, making them suitable for use in furnace and kiln transmission, sealing, and vibration damping devices. Their contraction and expansion accurately reflect the furnace's production status. However, during equipment maintenance, repair, or replacement, these springs often need to be disassembled. Due to the significant compressive force they experience, traditional disassembly methods often require the use of hammers, wrenches, and other tools for striking and prying, which is not only cumbersome and inefficient but also prone to damaging the spring itself and surrounding mechanical components. More seriously, the sudden release or ejection of the spring during disassembly can pose a safety hazard to operators, causing personal injury. Utility Model Content

[0005] A device for disassembling a truncated cone spiral spring includes a first baffle, a second baffle, a jack, an inner nut, an outer nut, and a spring baffle. The truncated cone spiral spring is fitted onto a support rod. The first baffle, the second baffle, and the spring baffle each have a hole at their center with a diameter larger than the outer diameter of the support rod. All three baffles are fitted onto the support rod. The spring baffle presses against the top of the truncated cone spiral spring. The inner nut is located on the side of the spring baffle away from the truncated cone spiral spring, and the outer diameter of the spring baffle is larger than the outer diameter of the inner nut. The first baffle is located on the side of the inner nut away from the spring baffle, and there is a distance between the first baffle and the inner nut. The second baffle is fitted over the inner nut and is tightly against the spring baffle. A jack is located between the first baffle and the second baffle. The outer nut is located on the side of the first baffle away from the jack.

[0006] Furthermore, the jack includes a vertical jack, a spiral jack, a split jack, or a rack and pinion jack.

[0007] Furthermore, the first baffle and the second baffle are provided with grooves that are adapted to the jack.

[0008] Furthermore, the inner walls of both the inner nut and the outer nut are threaded, and the surface of the support rod is provided with threads that match the inner nut and the outer nut.
