Abstract

The invention discloses a high-strength blended chair swing gear and a manufacturing method thereof, comprising the following steps: S1: designing a matching injection mold according to a pre-designed gear structure, and then processing and manufacturing the injection mold; S2: Fully mix the metal powder and the binder, and then granulate; S3: Inject the granulated mixture into a preform through an injection mold; S4: Put the preform into the extraction liquid, and remove the binder; S5: putting the prefabricated body without the binder into the sintering furnace for sintering to obtain the gear member. The high-strength blended chair swing gear and its manufacturing method provided by the present invention replace the existing aluminum die-casting or zinc die-casting manufacturing process, adopt new metal alloy powder injection molding, and greatly improve the various aspects of the swing gear. Mechanical performance, enriching the structural shape of gear parts, bringing various design styles to chair designers.

Description

technical field [0001] The invention relates to a furniture accessory, in particular to a high-strength blended chair swing gear and a manufacturing method thereof. Background technique [0002] The chair rocking gear needs certain mechanical strength, wear resistance and surface hardness due to the rocking back and forth. Most of the components currently on the market use aluminum or zinc as materials, and the products are made by die-casting process. The test standard for the swing gear is: put a 102kg weight on the chair cushion, and then swing it back and forth for 120,000 cycles. It is required that the parts should not have defects such as cracks, deformation, and collapse. Due to the softness of aluminum and zinc materials, they often fail to meet the test requirements. In order to meet the test requirements, it is necessary to thicken and thicken the gear parts, or increase the overall size, which takes up a lot of space, thereby limiting the space for other parts ...
