Изобретение относитс к обработке металлов давлением, в частности к оснастке дл гофрировани металлической ленты.The invention relates to the processing of metals by pressure, in particular to a tooling for corrugating a metal strip.

Известно устройство дл гофрировани лио товых заготовок, содержащее два взаимодействующих друг с другом через обрабатываемую заготовку параллельн1;1х вращающихс профилированных валка 11 оA device for corrugating cast billets is known, which contains two interacting with each other through the workpiece parallel1; 1x rotating profiled rolls 11 o

Однако это устройство имеет ограниченные технологические возможности, так как не предусматривает одновременно с гофрированием пробивку жалюзей на сторонах ленты.However, this device has limited technological capabilities, since it does not provide for punching of blinds on the sides of the tape simultaneously with the corrugation.

Известно также устройство дл гофрировани и пробивки жалюзей в фольге посредством , двух профилированных роликов, которые выполнены сборными из стальных пластин , выступающие части которых имеют форму ножа дл пробивки жалюзей. У оснований зубьев установлены упругие съемники 2.It is also known a device for corrugating and punching louvers in a foil by means of two profiled rollers, which are made in assemblies of steel plates, the protruding parts of which are shaped like a knife for punching louvers. At the bases of the teeth installed elastic puller 2.

Однако на известном устройстве могут быть изготовлены гофры только трапецевидной формы, что влечет за собой увеличение расхода материала и уменьшение коэффициента оребрени теплообменника.However, only trapezoid-shaped corrugations can be made on a known device, which entails an increase in material consumption and a decrease in the heat exchanger finning ratio.

Цель изобретени - возможность изготовлени пластин с гофрами треугольного сечени с калибровкой углового участка.The purpose of the invention is the ability to manufacture plates with triangular corrugations with calibration of the corner portion.

Поставлегша цель достигаетс тем, что в устройстве дл изготовлени гофрированных пластин теплообменников, содержащем пару зубчатых рюликов, собранных каж;дый из устаиовленных на общей оси пластин с заостренной крЪмкой, а также размещенные в продольных пазах во впадинах зубьев упругие This goal is achieved by the fact that, in a device for the manufacture of corrugated plates of heat exchangers, containing a pair of gear ryuls assembled each of the plates mounted on a common axis with a sharp edge and also placed in the longitudinal grooves in the pits of the teeth are elastic

10 съемники, имеющие форму, соответствующую форме пазов, каждый съемник выполнен в виде цилиндрического валика с продольной канавкой, кромки которой расположе1п.г над поверхност ми зубьев, а профиль выполts нен соответствующим профилю верщи п.1 зуба.10 pullers having a shape corresponding to the shape of the grooves, each puller is made in the form of a cylindrical roller with a longitudinal groove, the edges of which are located above the surfaces of the teeth, and the profile is made corresponding to the corresponding profile of item 1 of the tooth.

На фиг. 1 схематично изображены формующие ролики в зацеплении; на фиг. 2 - узел I на фиг. 1 (профиль зуба и съемники); на фиг, 3 - сечение А-А на фиг. 2 (сталь20 ные пластины зубьев, имеющие форму ножа).FIG. 1 schematically shows the forming rollers in engagement; in fig. 2 — node I in FIG. 1 (tooth profile and removers); FIG. 3 is a section A-A in FIG. 2 (steel plate 20 teeth shaped like a knife).

Claims

The device consists of two spauiaeMbix in opposite directions of the forming rollers 1 with teeth 2, having an angle of 45 points and assembled from steel plates 3, protruding around the periphery of which there is a drop down; in the form of knives. In the cavities there are cylindrical longitudinal grooves 4 for pullers 5, made from an elastic material of a polyurethane type. Each puller has a longitudinal groove 6, the Koropoii profile corresponds to the profile of the tooth tops, and the edges protrude above the lateral surface of the teeth by the amount of elastic deformation of the puller material. In addition, in FIG. 1 shows a corrugated tape 7, and FIG. 2 - the top 8 of the tooth 2.. The device works as follows. We crimp a) belt 7 serves to rotate in opposite directions the forming rollers 1 with teeth 2. The tooth is corrugated with simultaneous cutting. blinds. In view of the fact that the removals 5 are made of an elastic material, the teeth 2 with the vertices 8 deform the grooves 6 and make the minting of a given radius, corrugation. When teeth 2 come out of engagement, the pullers 5 remove the corrugated tape 7. The proposed device provides for making triangular sections in the belt by engaging the teeth of the 45 ° rollers, as well as chasing the top by making the puller with a longitudinal groove, which corresponds to the tooth apex profile and protrudes above the lateral surface of the teeth95 4 ev for the amount of elastic deformation of the material of the puller. In turn, the design of the cooling plate with a triangular cross section of the corrugation saves tape, improving the quality of the brazing of the cooling plate. the heat exchanger tube and the increase in the last ribbing factor. The invention The device for the manufacture of corrugated plates of heat exchangers, containing a pair of toothed rollers, assembled each of a wafer on a common axis of the plates with a pointed edge, and also located in the longitudinal grooves in the cavities of the teeth, elastic pullers having a shape corresponding to the shape of the grooves, characterized by that In order to be able to manufacture plates with triangular corrugations with the calibration of the corner section, each puller is made in the form of a cylindrical roller with a longitudinal groove, the edge of which is second races are put on surfaces of teeth, and about fil formed corresponding to the profile of the tooth top.
