Description
Technical Field
The invention relates to a mold, in particular to a composite material round-link chain forming mold.
Background
The round-link chain is also called as an annular chain, the structure is a common chain structure, a single round-link chain link comprises an upper round ring, a lower round ring and a middle section, a long-chain structure is formed by adopting a mode that the round rings are mutually sleeved with the round rings, and the round-link chain has the advantages of high load-carrying strength, good operation flexibility and the like. The method is applied to the fields of heavy machinery such as cranes, airplane hangar tying, mining equipment, ships, roadways, wharf transportation and the like.
As early as 1999, the general code for mooring rigging of ship helicopter released by the people's liberation force of china stipulates the technical requirements of the circular chain in steel mooring rigging of ship helicopter, quality assurance and preparation for delivery. The load capacity of the mooring rigging is required to have no permanent deformation and damage under a verification load, the load before breakage is required to be not less than a specified value, the load capacity of the mooring rigging with the chain diameter of 14mm is required to be not less than 124kN in use, the verification load is not less than 173.6kN, the breakage load is not less than 248kN, and the mooring rigging is required to have proper impact resistance without damage and crack when repeatedly falling to a clamping plate. Until now, round link chains have been widely used, particularly for load carrying equipment. The related standard of crane short-chain is released in 1999, and the specific size of the steel short-chain and the related requirements of the welding seam are specified.
However, most of the existing round-link chains adopt a metal structure, and each section of the round-link chain is welded after being sleeved, so that the steel-structure round-link chain is high in quality, time and labor are wasted during operation, in addition, the requirement on the welding seam of the round-link chain is high, the processing difficulty of the sleeved round-link chain is high, and meanwhile, the welding seam also easily generates certain defects to influence the properties of the linked mechanics and the like and reduce the product qualification rate. Markforged, U.S. 3D printing company, used 72 hours in 2016 to print a segment of a circular chain using carbon fiber material and conducted experiments to eventually break the link at 22000 pounds (about 10 tons). It has the advantages of heavy load, high strength, light weight and the like.
Nowadays, the development of the composite material round-link chain is slow, few manufacturers in China can integrally manufacture the round-link chain meeting the requirements, the density of the composite material is far lower than that of steel materials, and the strength of the composite material is far higher than that of steel materials, so that the composite material becomes the best material for manufacturing the round-link chain.
In addition, because the composite material round-link chain is of a closed-loop structure, the mold is complex in design and difficult to form, and a mature manufacturing process does not exist. The invention can solve the key problem of the structure forming of the closed round-link chain and can manufacture the round-link chain with high quality.
Disclosure of Invention
The invention aims to provide a composite material round-link chain forming die which can integrally form a composite material round-link chain and manufacture a high-quality and qualified composite material round-link chain.
The die is made of high-quality alloy steel, the material is subjected to preliminary heat treatment, after rough milling, further heat treatment is carried out, then electric machining and finish milling are adopted to obtain die parts, and finally the whole die is obtained through fitter trimming.
Because the combined material round-link chain is closed loop structure, this need concatenate an organic whole by every ring chain when making its shaping, simultaneously, for making things convenient for the circular arc interface drawing of patterns, should carry out the blocking processing to every ring chain link. The invention closes each circular chain link by a method of pressing four circular chain link die sleeves, and simultaneously, each section of circular chain link die sleeve is vertically staggered and positioned in the middle of an upper die and a lower die for pressing.
In the composite material round-link chain forming die, each round-link chain is firstly wound by prepreg fibers and is pre-pressed by a special tool, after pre-pressing forming, each round-link chain is sleeved into a round-link chain die sleeve and is placed at the forming part of a lower die, and finally the upper die is covered and the die is subjected to hot pressing for a certain time to obtain the whole round-link chain. The ring chain link that the level was placed can carry out the compression moulding through the forward pressure of upper and lower mould, and the ring chain link of vertical placing, when upper and lower mould extrusion, ring chain link die sleeve will produce certain horizontal pressure through the concentric arc surface of ring chain link in the upper and lower mould to can make the ring chain link of vertical placing obtain better suppression effect.
Compared with the prior art, the invention has the following advantages:
1. the invention can quickly and integrally manufacture and mold the high-quality composite material round-link chain.
2. The mould adopts a ring chain link mould sleeve structure to ensure that the composite material ring chain can obtain better pressing effect.
3. The invention can perfectly solve the problem of closed series connection of the composite material round-link chain.
