Abstract
The invention belongs to the improvement of braided steel wire enhancing sebific duct centreless weaving.Be characterized in braided steel wire to the second layer or the above enhancement layer of the second layer in interior pipe, keep high in pressure and do not have under the state of the braided steel wire shape of the mouth as one speaks and carry out.Thereby the interlayer that reduces adjacent enhancement layer is poor, has guaranteed that middle film fills fullly between enhancement layer, and the globality of sebific duct is strengthened, and withstand voltage properties such as its pulse life-span, burst pressure improve.
Description
The present invention relates to the improvement that a kind of braided steel wire strengthens sebific duct centreless weaving.
At present, the production technology of braided steel wire enhancing trombone slide can be divided into two kinds substantially: a kind of is that the core weaving is arranged, and another kind is the centreless weaving.Advantages such as the latter has the production efficiency height than the former, and production procedure is short, and joint length is long, and production cost is low, it is big to have braided steel wire density again simultaneously aspect product structure, helps body enhancement layer withstand voltage properties and improves.But, in the sebific duct with two-layer or multilayer braided steel wire is produced, it is big to exist enhancement layer interlayer difference, and the time have the middle film of interlayer to fill discontented phenomenon to occur, cause the globality of sebific duct poor, its pulse life-span and burst pressure descend thereupon, the centreless weaving is used in industrialization promotion be restricted.
The objective of the invention is that braided steel wire is strengthened sebific duct centreless weaving improves, provide a kind of interlayer that reduces the braided steel wire enhancement layer poor, the middle film filling that guarantees interlayer is full, thereby improves the globality of sebific duct and the weaving of its withstand voltage properties of assurance.
The object of the present invention is achieved like this: with the interior pipe sizing material behind the heat refining through Rubber Extruder, extrude the interior pipe of required specification, coil the semi-cure of pipe in carrying out immediately, in semivulcanized, charge into compressed air then in the pipe, make it well-pressed, through beater inner tube outer surface is carried out scutching and handle, the pressure that charges into air is at 0.2-0.4Mpa, then, in adjusting in the pipe air pressure be 0.1-0.2Mpa, finish through wire knitting machine that film carries out the first enhancement layer braided steel wire operation in the coating.Air pressure is (reduction with the inner tube diameter specification is increased) between the 0.5-1.1Mpa in the interior pipe of adjustment again, the braided steel wire shape of the mouth as one speaks on the removal braider, film enhancement layer braided steel wire in coating again, with the regulation enhancement layer count up to after, body coats outer glue through extruder, franking curls into sulfurizing pot vulcanization on the sulfuration drum.Sebific duct after the sulfuration is let out and is removed air pressure in the interior pipe, coils packing and gets final product.
The present invention is the improvement of carrying out on the basis of former centreless weaving, adopted to second or the above enhancement layer of the second layer high in press, no braided steel wire shape of the mouth as one speaks state weaves down, the advantage that has not only kept former centreless braided steel wire technology, and the interlayer difference of adjacent enhancement layer is reduced, film fully fills up therebetween in the interlayer, sebific duct globality after Bao Gaonei presses sulfuration improves, its pulse life-span and burst pressure also improve naturally, " playing cover " phenomenon when weaving is simultaneously eliminated, and also can save the enhancement layer steel wire.
Sebific duct with the two-layer braided steel wire of internal diameter φ 16mm is an example below, specify implementation process of the present invention: the internal diameter of extruding through Rubber Extruder be the interior pipe of 16mm coil finish into vulcanizing tank in the semi-cure operation of pipe, inwardly charge into compressed air in the pipe then, and keep-up pressure and be 0.2-0.4Mpa, and by beater to its outer surface scutching.Air pressure is to 0.1-0.2Mpa in the pipe in then adjusting, and warp loom finishes that the steel wire of film and first enhancement layer has the shape of the mouth as one speaks of braiding knitting process in the coating.In adjusting again in the pipe air pressure and lay down the braided steel wire shape of the mouth as one speaks on the braider, adjustment steel wire number of share of stock, braided pitch and angle of weave, the braided steel wire of the film and second enhancement layer in coating to 0.8-1.0Mpa.After finishing, press in the maintenance, coat outer glue, dipping, franking, curling, people's sulfurizing pot vulcanization on the sulfuration drum.Sebific duct after the sulfuration is let out and is removed interior pipe gas pressure, coils packing.
Claims (1)
1, a kind of braiding technology for braided steel wire reinforce ment of rubber hose, it is characterized in that the interior pipe sizing material behind the heat refining through Rubber Extruder, extrude the interior pipe of required specification, coil the semi-cure of pipe in carrying out immediately, in semivulcanized, charge into compressed air then in the pipe, make it well-pressed, through beater inner tube outer surface being carried out scutching handles, the pressure that charges into air is at 0.2-0.4Mpa, then, in adjusting in the pipe air pressure be 0.1-0.2Mpa, finish through wire knitting machine that film carries out the first enhancement layer braided steel wire operation in the coating; Air pressure is between the 0.5-1.1Mpa in the interior pipe of adjustment again, the braided steel wire shape of the mouth as one speaks on the removal braider, film enhancement layer braided steel wire in coating again, with the regulation enhancement layer count up to after, body coats outer glue through extruder, on sulfuration drum, curl, let out at last and remove in the interior pipe air pressure and coil packing into sulfurizing pot vulcanization.
