Abstract

The invention relates to welding, in particular to a device for mechanical cutting and butt-welding of thin sheet strips. The aim of the invention is to improve the quality. The device contains tables 7 for laying the strips mounted on the base, keyboard clamps with clamping elements 9 and 10, a cutting tool moving along the welding head 3 and forming a lining 4. Tables are made with T-slots and equipped with drive sliders placed in them Keyboard clamps are mounted on the sliders 11. When moving the sliders 11 with key clamps to the line of the butt of the strips, the waviness of the strips decreases along their butt joints before welding 4 or less. i (L

The invention relates to welding, namely to the construction of a device for mechanical cutting and butt-welding of thin sheet strips.

The aim of the invention is to improve the quality by reducing the waviness of the strips along their joint before welding.

The figo shows the proposed device, the cutting position; Fig 2 is the same in the welding position; in FIGURE 3, node 1 in FIG 2; figure 4 is a section along aa on the fi-goz.

The device contains a cutting tool consisting of disk 1 and side knives 2. moving along the welding torch 3, as well as shock-forming lining 4, clamps 5 and 6, tables 7 and 8 for laying 20 strips , keyboard clamps 9 and 10 with clamping elements, drive sliders 11 and 12 and their drives 13 and 14, as well as side stops 15 and 16 o

. Disk knife 1 is mounted on bearings 1 7 s. rotatable and mounted on a carriage 18 "The drive 19 of the outlet is mounted on the bed 20, the burner 3 is installed on the carriage; 21o A scraper 22 is fixed in front of the burner with the possibility of joint movement with it.

The carriages 18 and 21 are mounted on horizontal guides 23 and 24. The new lining 4 is fixed. When the carriage 18 is moved along the guides 23 and 24, the disk knife 1 is rotated in the bearings 17 and the two ends of the strips superimposed overlap each other are cut.

At the end and cutting of the ends of the strips, the lower trim enters the box, and the upper remains on the strip, turns on the actuator 19 and the knife 2 retracts the actuator 28 and replaces the knife 2 with the retracting device 25 with a backing pad 4, pre-adjusted in height with the help of nuts 26 and screws 27, so that the gap between the ends and the cover plate is set up, which is necessary for high-quality welding. The drives 13 and 14 of the drive sliders 11 and 12 are turned on and the key clamps 9 and 10 move, the protrusions of which lift the upper piece, after which it is positioned between the key 25. The clamps The curvilinear sample at the base of each clamping element ensures that the strip is guaranteed to press against the shock-forming lining 4 independent of its position relative to the level of clamping the strip with clamps 5 and 6 °

When moving the carriage 21 along the guides 23 and 24, the torch 3 welds the strips.

on the diverting device 25, which is sharply strips into a box, mounted

matched with a nut 26, which can be moved along the screw 27, the Bypass device 25 of the shoe-forming pad 4 and its actuator 28 are mounted on the frame 20, and the actuators 29 of the clamps 5 and 6 are mounted on it.

The device works as it should /

The ends of the outgoing and incoming strips are fed into the machine in such a way that the ends of the strips overlap each other about the side stops 15 and 16 of the strips are set in the transverse direction

The actuators 29 are turned on and the clamps 5 and 6 are lifted with the ends of the strips which are clamped between them and the tables 7 and In the Strip at the same time remain superimposed overlapped.

Simultaneously with the activation of the drives 29 of the clamps 5 and 6, the Drive 19 of the lower knife 2 is turned on, which is fed into the cutting zone

in the bed 20

At the end of welding, the driver 28 is turned on and the shoulder-shaped lining 4 is retracted, the side stops 15 and 16 are separated, the drivers 29 are turned on and the clamps 5 and 6 are lowered along with the strip

The welded strip is transported and the burner 3 and the disk knife 1 are returned to their original position.

The use of the proposed device increases the accuracy of the alignment of strips in height due to the convergence of the keyboard clamps before welding, which ensures a decrease in the waviness of the strips along their joint. Improving the precision of the alignment of strips in height improves the quality of the seam.
