После окончания прихватки подвижные опоры и плита раскрываются и изделие снимается с кондуктора цеховым краном или специальным грузоподъемным устройством для передачи на сварку.After tacking, the movable supports and plate are opened and the product is removed from the conductor by a workshop crane or a special lifting device for transmission to welding.

Известная конструкция кондуктора для сборки под сварку позволяет производить сборку коробчатых балок без диафрагм путем использования для фиксации элементов балки электромагнитов.The known design of the conductor for assembly for welding allows the assembly of box beams without diaphragms by using electromagnets to fix the elements of the beam.

Однако эта конструкция не решает вопроса съема собранного изделия без ис пользования дополнительных подъемно- . транспортных средств. Потери времени на, 'вспомогательные операции строповки и съема изделий ведут к снижению производительности сборочного контура.However, this design does not solve the issue of removal of the assembled product without the use of additional lifting. Vehicle. Loss of time on, 'auxiliary operations of slinging and removal of products lead to a decrease in the performance of the assembly circuit.

Claims

The invention relates to the mechanization of assembly and welding works, namely, the design of the stand for the assembly of metal structures for welding and can be used in the manufacture of welded metal structures on flow-mechanized lines. A known conductor for assembling, for welding, metal structures from sheet material, comprising a base on which supports and fixed supports are mounted. The stationary support is provided with a plate rotatable in a vertical plane with a plate with drive flanges for the vertical walls of the beam, while the displacement on the support is installed with the possibility of rotation from an individual drive in the vertical plane relatively to the base. Vani. A swivel bracket is mounted on the swiveling side of the movable support, which interacts with the locking bar of the movable support. The conductor works as follows. The vertical box-shaped sheet is mounted on a fixed support and fixed with electromagnets. With the help of a special drive through the levers, the fixed sheet is pressed against his system. The 1 horizontal horizontal sheet and the second vertical sheet are placed on the electromagnets of the folded supports, and on the rotary seal, in its open position, the upper horizontal sheet. After that, the swivel plates with the upper horizontal width are closed. Movable supports are rotated to the working position. The locking plates of the supports interact with the plate brackets, thus forming a closed loop; fixed support, folding plate, movable support. Vertically assembled and horizontal sheets fixed on electromagnets are a formed box section beam, which is ready to be joined by electric welding. After the tacking has been blocked, movable supports and ppita are opened and the product is removed from the conductor by a workshop crane or a special lifting device for transfer on welding. The known design of the conductor for assembly for welding allows assembly of box-shaped beams without diaphragms by using electromagnets for fixing elements of the beam. However, this construction does not solve the problem of removing the assembled product without using additional lifting equipment. Losses of time for auxiliary operations of slinging and removal of products lead to a decrease in the performance of the assembly circuit. Also known is a stand for assembling metal structures for welding, which contains a base on which movable and fixed supports with lodgings are mounted, between which there is a plate mounted on lifting rolling pins symmetrically with respect to the longitudinal axis of the stand, and a diverting inclination. However, the well-known stand is inefficient, since time is great for transferring products from the stand to the discharge ramp. The aim of the invention is to increase productivity by reducing the time taken to transfer the product from the stand to the discharge chute. This goal is achieved by the fact that the plate is pivotally mounted on rolling pins, is located 1X with CTopOHfci of the diverting inclined slope and is freely placed on other rolling pins, and on the diverting inclined slope there is an emphasis interacting with the plate in its inclined position. Fig, 1 schematically shows the main view of the stand; in fig. 2 shows section A-A in FIG. 1. The stand contains a base 1, on which a fixed support 2 and movable supports 3 mounted on hinges 4 and connected articulated to pneumatic chi / | indrom 5 with thrust 6 are mounted. middle element of the product. On the fixed and movable supports there are lodgments 8 and 9, respectively, with base bars 1O and 11, as well as pneumatic grips 12. At the level of the cradle 8 of the fixed support 2, a rotatable plate 13 is mounted, resting freely at one end of .14, ac on the other side with the end 15 through a hinge 16 on rolling pins, respectively, 17 and 18, rigidly connected by the cross member 19 and reciprocating in the guides 21 mounted on the base 1 using the pneumatic cylinder -20, an inclined chute 22 with an emphasis 23 is mounted on the discharge side rasp The inside of the base slats 10 and 11. The stand works as follows. In the initial position, the movable supports are in the diluted state, the pneumatic clamps are retracted from the base of the slats, the swivel plate is in the lowest position at the level of the lugs of the fixed support. First, place the middle element of the assembled product on the cradle 8 of the fixed support 2, orient the middle element c. using a dividing device 7, pressing against the base bars 10, and fixed in this position. Then, the extreme elements are laid on the cradles 9 of the movable supports 3 and fixed by means of pneumatic clamps 12 on the base rails 11. By means of pneumatic cylinder 5, moving pores are made and the extreme elements of the assembled product are set relative to the middle position of the tack, then tack is made. After the tacking is completed, the pneumatic compressors 12 are released, however, the assembled product remains in the stand clamped on the base bars 10 and 11, which are located on the fixed and movable supports. Therefore, the product must be pushed above the base slats, then removed from the stand. To do this, include a pneumatic cylinder 2O, which, through the yoke 19, informs the rolling pins 17 and 18 in the guides 21 forward movement upwards, raising the plate 13, with which the product is pushed out above the base bars 10 and 11. With a further rise, the rotary plate 13 interacts The end 15 with the stop 23 of the inclined chute 22 and on the hinge 16 rotates in the unloading direction, thus forming with the inclined slope a single inclined platform along which the product moves to the accumulator or to the conveyor to perform welding operations. The following welding stands are installed in the flow line, J Equipping the fixed support of the stand with the plate (or below it) on the cradle, supported by the rolling pin, is installed in the base elements with the possibility of reciprocating movement. base films The proposed device allows you to quickly remove the product without resorting to auxiliary devices from the outside. The plate is swivel in a vertical plane, loosely supported on one side and pivotally on the other on rolling pins, and the installation on the basis of an inclined ramp with a stop located above the base slats installed on fixed and movable supports makes it possible to transfer the product from the stand to the drive or conveyor for further technical operations. Such a constructive solution makes it possible to increase productivity by reducing the loss of time spent on product removal and ensures that the stand can be used in production lines without resorting to an auxiliary lift-and-vehicle vehicle. Claims of the Invention Stand for assembly of metal structures for welding, comprising a base with movable and fixed supports with lodgings between which a plate is placed, mounted on lifting rolls symmetrically with respect to the longitudinal axis of the stand, and an inclined chute that differs from that, with an increase in supply chain by reducing the time required to transfer the product from the stand to the discharge chute, the plate is hingedly mounted on rolling pins located on the side of the chute and but it placed on the other pin, and on retraction present oblique ramp adapted abutment with vzaimodeystvuk conductive plate in its tilted position.
