На фиг. 1 изображено предлагаемое устройство , вид сбоку; на фиг. 2 - то же, вид сверху; на фиг. 3 - разрез А-А на фиг. 1.FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one.

Устройство дл  сварки полимерных материалов газообразным теплоносителем содержит корпус 1 с окном 2, на котором смонтирована подвижна  рама 3, установленна  в подшипниках 4 скольжени , привод 5 возвратно-поступательного движени  рамы с кулисой 6 и т гой 7. Рама 3 св зана с т гой 7 шарнирно. Устройство содержит также ресивер 8 с соплами 9 дл  подачи в зону сварки нагретого газа и полую камеру 10, выполненную с обращенной в зону сварки продольной прорезью 11, в которой установлены подпружиненные при- каточные валки 12,A device for welding polymeric materials with a gaseous coolant comprises a housing 1 with a window 2, on which a movable frame 3 is mounted, mounted in slide bearings 4, a drive 5 of a reciprocating frame movement with link 6 and link 7. Frame 3 is connected with tension 7 pivotally. The device also contains a receiver 8 with nozzles 9 for supplying heated gas to the welding zone and a hollow chamber 10, made with a longitudinal slot 11 facing the welding zone, in which spring-loaded flush rollers 12 are installed,

Валки 12 расположены с зазором друг относительно друга, образу  окна 13 против каждого сопла 9 ресивера 8 дл  нагрева кромок термопласта струей газа. Сопла 9 расположены над валками по оси симметрии соседних валков на рассто нии 4-5 мм от плоскости свариваемого материала, что создает камеру 14 дл  газовой подупти, ограниченной вертикальными стенками камеры 10 и ресивером 8.

Возвратно-поступательное движение камере 10 в процессе сварки сообщает рама 3.The rolls 12 are arranged with a gap relative to each other, forming windows 13 against each nozzle 9 of receiver 8 for heating the edges of the thermoplastic with a stream of gas. The nozzles 9 are located above the rolls along the axis of symmetry of the adjacent rolls at a distance of 4-5 mm from the plane of the material being welded, which creates a chamber 14 for the gas sub-bounded by the vertical walls of the chamber 10 and the receiver 8. The amount of overpressure of the gas pillow in chamber 14 is set to 50-65% of the pressure of the gas jet coming out of the nozzles 9, and regulate through the exhaust channels 15.

Устройство работает следующим образом.The device works as follows.

На свариваемый участок шва накладывают антиадгезионную эластичную пленку, и устройство став т на стык таким образом , что продольна  ось щва находитс  посередине окна 2 корпуса 1. Собственным весом устройства или посредством механизма (не показан), воздействующего на корпус I, свариваемые кромки термопласта плотно прижимают друг к другу без зазора . Усилие прижима 0,05-0,2 МПа.An anti-adhesive elastic film is applied to the weld area of the seam, and the device is placed on the joint in such a way that the longitudinal axis of the seam is in the middle of the window 2 of the housing 1. The self-weight of the device or by means of a mechanism (not shown) acting on the housing I press the edges of the thermoplastic tightly to each other without a gap. The clamping force of 0.05-0.2 MPa.

От нагревател  (не показан) газ-теплоноситель подают в ресивер 8 через штуцер 16 и далее в зону сварки. Одновременно включают привод 5 и сообщают камере 10 с валками 12 в течение всего цикла сварки возвратно-поступательное движение.From the heater (not shown), the heat transfer gas is supplied to the receiver 8 through the fitting 16 and further to the welding zone. At the same time, the drive 5 is turned on and a reciprocating movement is communicated to the chamber 10 with the rollers 12 during the entire welding cycle.

При нагревании материал кромок термопласта разм гчаетс  и деформируетс . Под действием упругих сил объемного температурного расширени  термопласт прогибает вверх эластичную пленку между прикатывающими валками. Величина прогиба с ростом температуры нагрева материала возрастает и увеличивает объемную деформацию полимера.When heated, the material of the edges of the thermoplastic softens and deforms. Under the action of elastic forces of bulk temperature expansion, the thermoplastic bends upward the elastic film between the press rolls. The magnitude of the deflection with increasing temperature of the material increases and increases the volumetric deformation of the polymer.

Соверща  возвратно-поступательное движение , прикатывающие валки создают касательные к плоскости свариваемого материала силы К, которые накладывают деформации сдвига на материал и его расплав. Термопласт до начала сварки помещен в ограниченный объем, и деформации объемного сжати , создава  силы дл  взаимного соприкосновени  и проникновени  макромолекул в плоскости сваривани  расплава кромок теромпласта, обеспечивают перемешивание и активацию макромолекул термопласта по сечению и оси шва.By reciprocating, the pressing rolls create tangential forces K to the plane of the material being welded, which impose shear deformations on the material and its melt. Prior to welding, the thermoplastic is placed in a limited volume, and the deformations of volumetric compression, creating forces for the mutual contact and penetration of macromolecules in the plane of welding of the melts of the thermoplastic edges, ensure the mixing and activation of macromolecules of the thermoplastic along the section and axis of the seam.

Нагрев кромок прекращают при достижении ими температуры в зкотекучего состо ни  или температуры сварки, т.е. прекра- ш,ают подачу газа-теплоносител , а наложение сдвиговых и объемного сжати  деформаций продолжают до окончани  цикла сварки, включающего нагрев термопласта и формировани  сварного шва до охлаждени  (достижение термопластом температуры стекловани ).The heating of the edges is stopped when they reach the temperature in the flowing state or the welding temperature, i.e. The heat carrier gas flow ceased, and the shear and bulk compression deformations continue until the end of the welding cycle, which includes heating the thermoplastic and forming a weld before cooling (reaching the glass transition temperature by the thermoplastic).

По окончании сварки выключают привод 5 и устройство перенос т на другой участок щва дл  последующей сварки.At the end of welding, turn off the drive 5 and the device is transferred to another area of the joint for subsequent welding.
