Abstract

The invention relates to welding, in particular, to the design of a stand for welding products with a curved surface, mainly finned floorings of the shells of combine harvesters such as Don-1200 and Don-1500. The aim of the invention is the expansion of technological capabilities. The stand comprises a housing 6 rotatable on axis 5 for the product to be welded 3, a portal with a guide 9 on which a carriage 10 with a power cylinder 13 is mounted. A support roller 14 and a welding torch are mounted on the cylinder rod 13. The rotary body 6 is equipped with a mechanism for installing the product 3 into the welding position, made in the form of a cable 18 and tapping blocks 19. The ends of the cable 18 are connected to the ends of the body 6. When the carriage 10 moves, the support roller 14 presses on the product 3, and the body 6 rotates. provides welding of products of different curvature, since the copier is the contour of the product being welded 3. 5 Il. i (L

The invention relates to welding, in particular, to the design of a stand for welding products with a curved surface, mainly finned floorings of the headers of combine harvesters such as Don-1200 and Don-1500.

The aim of the invention is the expansion of technological capabilities by ensuring the manufacture of products of different curvature.

Figure 1 shows the proposed stand for welding products with a curved surface, top view; in d.2 - view A in figure 1} in fig. 3 - view B in figure 2 in figure 4 - node I in figure 2, in figure 5, the kinematic scheme. ma booth for welding.

The stand for welding products with a curved surface contains control equipment 1 mounted on the base, a trolley 2 for moving the product 3 (flooring) to the stand a portal with support posts 4 to which the rotary body 6 and beams 7 and 8 with guides are attached to the stand 5. 9. Along the guides 9, the carriages 10 and 11 move in front of the welding torch 12 in a horizontal plane. The welding torch 12 is connected to the stem of the power cylinder 13. The support rollers 14 are mounted on the stem of the power cylinder 13. Welding contains fixed on the base stops 15, made with inclined surfaces for centering the product 3 and stops 16 to drive them from the cylinders 17. The ends B and C of the housing are connected by a cable 18, which passes through the tap-off blocks 19 fixed on the portal.

Stand for welding products with a curved surface, mainly decking hull headers, works as follows.

The flooring 3 enters the Stand with the help of the trolley 2, which raises it to the required level and locks the cylinders 17c here with the help of the stops 15 and 16 in space with simultaneous straightening on the centering surfaces of the stops 15. Then the welding torch 12 bypasses by a given apparatus 1 program management

all weld sites and welds according to the following cycle: from the initial position using carts 10 and 11

the burner 12 moves along the guides 9 to the welding point, and then the power cylinder 13 moves the burner 12 vertically down to the floor 3 and receives a sheet by supporting rollers 14

to the stiffening ribs of the flooring, and in the curvilinear sections it also rotates the body 6 around the axes 5 of the CMM so that the welding torch 12 is perpendicular to

surfaces of the welded flooring 3. When the welding torch is moved, welding and rotation of the housing 6 takes place, and its sides B and C make equal movements, and the cable 18

also moves along side blocks 19 and eliminates all unacceptable floor deflection in all positions of housing 6.

The bench for welding products with a curved surface has wider technological possibilities due to the provision of welding products of different curvature, since the copier is the contour of the product being welded.

Claims (1)

Invention Formula Stand for welding products with a curvilinear surface, predominantly ribbed deck for the header shells, containing a housing for the product to be welded with the product installation mechanism in the welding position, a portal mounted on the base, and a carriage mounted on it with the ability to move with a pressure cylinder attached to one of them on stock the copier roller and welding torch are installed, which differs from the fact that, in order to expand technological capabilities by providing welding of products of different curvature, the mechanism of installation of the product into the welding position is provided with a cable, bypass blocks and stops, while the bypass blocks are fixed to the portal, the cable through the tap-off units is connected with its ends to the ends of the rotary body, and the stops are fixed on the base at the end sections of the rotary body.
