Description

Изобретение относится к сварке, а имен- , но к устройствам для сварки по копиру деталей криволинейного контура, например, канистр.The invention relates to welding, and name-, but to devices for welding by copying parts of a curved contour, for example, canisters.

^! По основному авт. св. № 766805 известно устройство для автоматической сварки криво- 5 линейных изделий, преимущественно с прямолинейными и закругленными участками,содержащее смонтированные йа основании сварочную головку, кронштейн с ложементом для изделия и копиром, ведущий ролик, взаимо- ^,0действующий с внутренней поверхностью копира, и подпружиненный рычаг с ведомым роликом, взаимодействующим с копирной дорожкой, смонтированной на наружной поверхности копира. При этом на наружной ¹⁵поверхности копира параллельно основной смонтирована дополнительная копирная дорожка, на прямолинейном участке каждой дорожки выполнена канавка, причем на одной из дорожек. канавки размещены по одну сторону от закрепленного участка копира, соединяющего два прямолинейных участка, а на другой дорожке канавки размещены по другую сторо2 ну от этого участка, при этом на рычаге смонтирован дополнительный ведомый ролик, взаимодействующий с дополнительной дорожкой копира (1]. ^! According to the main author. St. № 766 805 discloses a device for automatic welding of articles along curved line 5, preferably with straight and curved portions, comprising mounted ya based welding head, with a lodgment bracket for the product and the cam, the drive roller ^{interacting, 0} acting from the inside surface of the copier, and a spring loaded a lever with a driven roller interacting with a copy path mounted on the outer surface of the copier. Moreover, on the outer ¹⁵ surface of the copier, an additional copy path is mounted parallel to the main one, a groove is made in a straight section of each track, moreover, on one of the tracks. the grooves are located on one side of the fixed portion of the copier connecting the two straight sections, and on the other track, the grooves are placed on the other side of this section, and an additional driven roller interacting with the additional path of the copier is mounted on the lever (1].

Недостатком этого устройства является низкое качество свариваемого изделия, заключающееся в выпучивании зоны шва из-за жесткости закрепления изделия между ложементом и копиром.The disadvantage of this device is the low quality of the welded product, which consists in buckling of the weld zone due to the rigidity of fixing the product between the tool tray and the copier.

Цель изобретения - повышение качества изделия путем исключения выпучивания зоны шва.The purpose of the invention is to improve the quality of the product by eliminating buckling of the weld zone.

Поставленная цель достигается тем, что устройство снабжено компаратором деформации изделий, выполненным в виде эластичных прокладок, установленных на обращенных друг к дру!у плоскостях ложемента и копира.This goal is achieved by the fact that the device is equipped with a comparator for deformation of products made in the form of elastic gaskets mounted on the planes of the tool tray and the copier facing each other!

На фиг. 1 изображено предлагаемое устройство, общий вид; на фиг. 2 — сечение А—А на фиг. 1.In FIG. 1 shows the proposed device, a General view; in FIG. 2 - section A — A in FIG. 1.

Устройство для автоматической сварки содержит смонтированные на основании 1 двухшарнирный кронштейн 2 с поворотным валом 3, пневмоцилиндром 4 для зажатия заготовок изделия и закрепленным на валу 3 копиромA device for automatic welding comprises a double-hinged bracket 2 mounted on the base 1 with a rotary shaft 3, a pneumatic cylinder 4 for clamping the workpieces of the product and a copier mounted on the shaft 3

5. На основании установлены также электродвигатель 6, кинематически связанный с ведущим роликом 7, взаимодействующим с внутренней поверхностью копира 5, соответствую- j щей контуру свариваемого изделия 8, а также рычаг 9 со смонтированными на оси 10 роликами 11 и 12 и горелка 13· со следящим роликом 14.5. On the basis of the installed electric motor 6, kinematically connected with the drive roller 7, interacting with the inner surface of the copier 5, corresponding to the j contour of the welded product 8, as well as the lever 9 with the rollers 11 and 12 mounted on the axis 10 and the burner 13 follower 14.

На плоскости копира 5 и верхнего ложемента 15 установлены прокладки 16, обеспечивающие зажатие заготовок, изделия 8 только на закругленных участках. В процессе сварки нагрузка от пневмоцилшздра 4 передается на заготовки изделия 8 через верхний ложемент Л5 и прокладки 16, тем самым обеспечивается надежная фиксация стыка заготовок по всему контуру и вместе с тем свободное, тепловое расширение изделия при сварке.On the plane of the copier 5 and the upper lodgement 15, gaskets 16 are installed, providing clamping of the blanks, products 8 only in rounded areas. In the process of welding, the load from the pneumocylsdra 4 is transferred to the workpieces of the product 8 through the upper lodgement L5 and gaskets 16, thereby ensuring reliable fixation of the joint of the workpieces along the entire contour and, at the same time, free, thermal expansion of the product during welding.

Использование предлагаемого изобретения по сравнению с известным позволяет повысить качество свариваемых изделий за счет исключения выпучивания зоны шва.The use of the invention in comparison with the known one allows to improve the quality of welded products by eliminating buckling of the weld zone.

Claims

The invention relates to welding, in particular to devices for welding on a copy of parts of a curvilinear contour, for example, canisters. According to the main author. St. No. 766805 discloses a device for automatic welding of curvilinear products, preferably with straight and rounded sections, comprising a ha-mounted welding head, a bracket with a dp product and a copier, a drive roller interacting with the inside surface of the copier, and a spring-loaded lever with a driven roller interacting with a copier track mounted on the outer surface of the copier. At the same time, an additional copier track is parallel to the main copy surface of the copier, a groove is made on the straight section of each track, with one of the more expensive grooves located on one side of the fixed section of the copier connecting the two straight lines and the other track of the groove Placed on the other side of this section, with an additional driven roller mounted on the lever, which interacts with the copier's additional track {. The disadvantage of this device is the low quality of the product being welded, which consists in the buckling of the zone of the seam due to the rigidity of the fixation of the product between the cradle and the copier. The purpose of the invention is to improve the quality of the product by eliminating the bulging of the seam area.

FIG. 1 depicts the proposed device, the communities view; in fig. 2 is a section A-A in FIG. I. The automatic welding device dp contains 1 double-hinged bracket 2 mounted on the base with a rotary shaft 3, 4 dp pneumatic workshop and 3 98 products are fixed with a copier fixed on the shaft 3 5. The base also has an electric motor 6, kinematically connected with the driving roller 7 interacting with the inner surface of copier 5, corresponding to the contour of the product to be welded 8, as well as lever 9 with rollers I and 12 and the burner 13 mounted on the axis 10 with the following roller 14. On the plane of copier 5 and the upper lodgement 15 SET zhleny gasket 16, obespechivayuishe clamping workpieces article 8 only at the rounded portions. In the process of welding, the load from the pneumatic cylinder 4 is transferred to the workpieces 8 through the upper cradle 15 and gaskets 16, thereby ensuring reliable fixation of the blanks from the whole contour and at the same time free, thermal expansion of the product during welding. The use of the present invention in comparison with the known one allows to improve the quality of the products being welded by eliminating the bulging of the seam zone. The invention The device for automatic welding of curvilinear products according to ed. St. N 766805, characterized in that, in order to twist the products by eliminating the bulging of the seam zone, the device is equipped with a deformation compensator for the products made in the form of elastic pads installed on the planes of the lodgement and the copier facing each other.
