Abstract
The invention discloses an ultrastrong aluminum alloy heald frame for a shuttleless loom and a production process thereof. The ultrastrong aluminum alloy heald frame comprises heald frame beams, guide plates, side rails, connectors and heald penetrating rods, wherein the heald frame beams and the side rails are made from the aluminum alloys with the addition of 0.08%-0.16% of silicon, 0.65%-0.85% of magnesium, 0.10%-0.20% of ferrum, 0.01%-0.06% of copper and 1.00%-8.50% of zinc relative to a total amount in the fusion casting process. The production process of the ultrastrong aluminum alloy heald frame comprises the following steps of: adding the alloys; casting aluminum bars; extruding; carrying out oxidation treatment; cutting; assembling; detecting, and warehousing. The ultrastrong aluminum alloy heald frame has the advantages of high mechanical properties including tensile strength, hardness, and the like, reasonable structure, good straightness, long service life, suitability for the requirements of the current novel high-speed shuttleless loom, and the like.
Description
technical field [0001] The invention relates to a key device for a shuttleless loom, in particular to an alloy aluminum heald frame for a shuttleless loom. Background technique [0002] The existing aluminum alloy heald frames used for shuttleless looms generally have a tensile strength of 220Mpa and a hardness of 75HV, which cannot meet the high speed requirements of international new shuttleless looms above 800r / min in recent years. breakage, short lifespan. Contents of the invention [0003] The purpose of the present invention is to provide a super-strong alloy aluminum heald frame with high mechanical properties such as tensile strength and hardness, reasonable structure, good flatness and long service life, which can meet the weaving needs of today's new high-speed shuttleless looms. Production Process. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions. Super-strong alloy aluminum heald frame...
