Gluing process used for gluing of metal

Abstract

The invention discloses gluing processes used for gluing of metal. According to procedures of the gluing process used for gluing of the metal, nylon particles are selected as gluing materials, the nylon particles are dried and then are placed in a heating area of an injection molding machine so that the nylon particles are heated and melt into fluid and then flow to connecting positions of metal pieces at uniform velocity; the injection molding machine is adjusted, the injection molding space of the injection molding machine is adjusted to be matched with the overall dimension length of the metal after connection, and then temperature time is set; and the injection molding machine is started, material feeding is conducted from a front face and a back face for injection molding, and demolding is carried out to take out a finish product piece after the injection molding is finished. By means of the gluing process used for gluing of the metal, the glued finish product piece is good in intensity and other performance, can be solidified rapidly after gluing, can come into service in the first time, does not affect the effect, and is easily popularized and applied in actual production.

Description

technical field [0001] The invention relates to a bonding process, in particular to a fast solidifying bonding process for bonding metals. Background technique [0002] At present, epoxy resin infusion is usually used to bond metal parts together in the production process. For example, the bonding process for bonding insulating gauge tie rods is as follows: fix the seamless steel pipe on the perfusion frame, Install a rubber pad in the center to isolate the pull rods at both ends and prevent glue leakage; pour the prepared epoxy resin (20% accelerator should be added when adjusting) into the seamless steel pipe; insert one end in time Fix the pull rod on the pouring rack, dry it, turn it around after solidifying for 12 hours, and pour the other end according to the method of the second part, and dry and solidify for 12 hours before taking it off the shelf for inspection (according to the iron standard TB / T2492-2004 standard ) Insulation, bending vector, total length, tensi...

[0002] At present, epoxy resin infusion is usually used to bond metal parts together in the production process, such as the bonding process for bonding insulating gauge tie rods The process is as follows: fix the seamless steel pipe on the pouring frame, and install a rubber pad at the center of the pipe, which can play the role of isolating the pull rods at both ends and preventing glue leakage; the prepared epoxy resin (should be added when adjusting 20% accelerator) into the seamless steel pipe; insert one end of the pull rod in time to fix it on the perfusion rack, dry it, turn it around after solidifying for 12 hours, and then pour the other end according to the method of the second part, and dry and solidify for 12 hours. Only then can it be removed from the shelf for inspection (according to the iron standard TB / T2492-2004 standard), insulation, bending vector, total length, tensile performance (3% random inspection is done on the testing machine for tensile test), appearance and other inspections (the thread length at both ends is 350 Pre-inspection); although this method can also bond them together, the curing time takes about a week, which is too long to be put into use quickly, and the strength, insulation and other properties are not very good, which cannot meet the needs of production. application requirements
