Abstract

The invention relates to the field of welding, in particular to equipment for the assembly and subsequent contact roller welding of metal shells, and can be. Used in various sectors of the national economy. The purpose of the invention is the expansion of technological capabilities by increasing the range of sizes of welded shells, increasing productivity and simplifying the design. Rolled shell using lifting means is installed on support beam 7 with lining and on rollers 12 and 13. The support b is rotated around axis 11 and lifted by a screw pair all the way into beam 7. The overlap mechanism 10 starts on both sides and is fixed with locking elements. A tacking of the ends of the edges of the shell with a welding device is performed. The finished shell along the guides 3 is moved under the welding rods of the machine. The device will allow the assembly of the shell outside the welding machine. Replacing the seam joints with contact roller welding increases the reliability and quality of the shells. 3 il. about S (/) С f

Description

The invention relates to equipment for the assembly and subsequent contact roller welding of metal shells and can be used in various industries of the national economy.

The purpose of the invention is the expansion of technological capabilities by increasing the range of sizes of welded shells, increasing productivity and simplifying the structure.

FIG. 1 shows schematically the proposed device, a general view; in fig. 2 - the same, side view; in fig. 3 is a view A of FIG. t.

The device for assembling the shells consists of a frame 1 mounted on the rollers 2 moving along the rails 3. On the frame 1 is mounted on three pillars. 4-6 support beam 7, to which the conductive forming pad 8 and fixing elements 9 are attached, and Attachment mechanisms 10 are installed at its ends. Supports 4 and 6 are made to rotate around an axis 11 in a vertical plane passing through the longitudinal axis of the support beam, and support 6, in addition, has the ability to be adjusted with a screw pair . In the middle part of the frame 1, the rollers 12, which are the lower support of the shell, and the rollers 13, which are the lateral supports of the shell, are mounted with the possibility of adjustment.

The device works as follows.

The rolled shell using underground means (not shown) is mounted on the beam 7 with the lining 8 and on the rollers 12 and 13, and the support 6 is rotated around the axis 11 and lifted by a screw pair all the way to the ball

7. An overlap mechanism 10 is set up on two sides and fixed by elements 9, then the tips of the edges of the shell are tacked with a welding device (not shown), and the ready shell is guided along guide rails 3 under the welding rollers of the maschine (not shown).

The use of the invention permits the assembly and tacking of the shell outside the welding machine, which results in an increase in the yield yield of the finished products, and the replacement of the fold joints of contact roller welding increases the reliability and quality of the sheaths.
