(54) DEVICE FOR ASSEMBLING UNDER WELDING BEAMS

(57) The invention relates to welding and can be used, for example, when assembling I-beam beams consisting of a wall and two sidewalls for welding. The purpose of the invention is to increase reliability, reduce energy costs and expand technological capabilities. The sidewalls 2 of the assembled beam are laid on the lodgments 5, and the wall 1 is placed on the supporting surface 4. When the rods of the rotational drives 11 are lowered down, the lodgements 5 with the sidewalls 2 rotate 90 ° before interacting with the stops 13. In this position, the sidewalls 2 are welded to the wall 1 After welding by means of actuators 9, they tilt the pillars 6 by an angle a, ensuring the free removal of the finished beam. After removing the finished product, the device is reset. In this case, the tilt drives 9 press the supports 6 to the limiting stops 10, and the cradle 5 is set to its initial position, raising the rods of the turning actuators 11 and turning 90 ° due to the offset center of mass. This design provides increased reliability, reduced energy consumption by reducing drive power, and the ability to adjust allows you to assemble beams of various sizes. 1 z p f-ly. 5 yl

The invention relates to welding, in particular to ancillary equipment for assembly and welding, and can be used, for example, in assembling I-beams consisting of a wall and two sidewalls.

The purpose of the invention is to increase reliability, reduce energy costs and expand technological capabilities.

FIG. 1 shows a device for assembling beams for welding, the initial position; in fig. 2 - the same, intermediate position; in fig. 3 - the same working position; in fig. 4 is a view along arrow A in FIG. 3; in fig. 5 - the same position when removing the product.

A device for assembling beams for welding, consisting of wall 1 and two sidewalls 2, contains a base 3 with a supporting surface 4 for a wall 1 of the assembled product, lodgments 5 for sidewalls 2 Lodgements 5 are mounted on racks 6 with a 90 ° rotation, with centers the masses of the cradle are located relative to the horizontal axis of rotation 7 in such a way that in the unloaded state the cradle spontaneously occupy the initial position. Racks 6 are mounted on sliders 8 with the possibility of deviating to one side from the vertical plane by an angle a. The tilt of the pillars 6 is carried out using drives 9, also mounted on the floor 00

zoonah 8. To prevent the racks 6 from tilting in the opposite direction and keeping them in a vertical position at an angle of 90 ° relative to the horizontal plane, the device is provided with stops 10. Rotation of the cradle 5 is carried out using actuators 11 made in the form of tilted relative to the vertical supports of the power cylinders, the rods of which are connected to the cradles through the hinge rods 12. To restrict the turn of the cradles 5 to an angle greater than 90, the pillars 6 are provided with stops 13. To readjust the cradles 5 for different types The dimensions of the sides of the assembled beams of the cradle are equipped with adjustable stops 14. For the synchronization of the operation of the device, links 15 are used that connect the cradle 5 located on one side of the device.

The assembly for welding works as follows.

Depending on the dimensions of the batch of products, the device is adjusted using sliders 8 and adjustable stops 14 to the given size according to the formulas:

X - with the height of adjustable stops 14, greater than or equal to 6g (see Fig. 1), where X is the distance from the axis of symmetry of the device to the axis of rotation 7 of the cradle 5:

Y is the distance from the axis of rotation of 7 lodgements 5 to adjustable stops 14;

W - wall width 1;

B2 - sidewall width 2;

(5i - wall thickness 1;

(52 - sidewall thickness 2;

a is the distance from the axis of rotation of 7 lodgements 5 to their surface;

b is the distance from the axis of rotation 7 of the cradle 5 to the support surface 4.

In the initial position, the rods of the actuators 11 are in the extreme upper position, and the cradle 5 is in the horizontal position. The actuators 9 clamp the pillars 6 to the limiting stops 10. The sides 2 of the assembled product are laid horizontally on the cradle 5 until they interact with the adjustable stops 14, the wall 1 of the I-beam is laid horizontally on the + supports (52 + a;

4 surface (see. Fig. 1). When lowering the rods of the rotational drive drives 11, the lodgements 5 with the sidewalls of 2 I-beams turn 90 ° to interact

with stops 13. In this case, the sidewalls 2 become vertical. In such a position, sticking or welding 2 with the wall of 1 I-beam is made (see Fig. 2 and 3). For product removal, tilt drivers 9 tilt

stand 6 at an angle a, thereby contributing to the free removal of the product from the device (see Fig. 5). After removing the product, the device is set to its original position. At the same time, the tilting actuators 9

they press the pillars 6 to the limiting stops 10, the rods of the swivel drives 11 rise upwards, and the cradle 5 are set to the initial position, turning 90 ° due to the offset center

masses Such a device design allows to automate the operation of assembling and welding various sizes of long beams of predominantly I-beams, to increase reliability,

improve production culture, reduce energy consumption of equipment.
