Description

I; .

The invention relates to welding and can be used in the manufacture of cylindrical metal carriages of houses, large-diameter smoke-exhaust pipes, etc.

A device for manufacturing thin-walled containers with stiffening rings, comprising a welding head and a sheet panel table mounted on the base and a turning drum for stiffening rings mounted with the possibility of longitudinal movement and equipped with a cable clamp of the Sheet canvas on stiffening rings. However, this device is manufactured sequentially. winding the sheet of cloth on the ring stiffness and tacking and welding, which reduces the quality of welding and plant performance.

The closest in technical essence and the achieved result to the proposed is the installation for

assembling and welding thin-walled cylinder-hous buildings with stiffness rings J bone, containing mounted on the base of the sheet sheet and a mechanism for winding the sheet tissue onto stiffening rings with welding heads equipped with feed rollers for welding

, wires, as well as the clamping of a sheet of cloth to stiffening rings including supporting and guiding rollers C

The disadvantages of the installation are low productivity, the impossibility of carrying out continuous welding of the sheet to the rings of stiffness and matching the speed of rotation of the drum with the supply of welding wire.

The purpose of the invention is to increase productivity and ensure continuity of winding and welding with a predetermined pitch of the sheet.

to stiffening rings 3 The goal is achieved by the fact that the mechanism for winding a sheet of cloth onto stiffening rings is designed as installed on the base with the possibility of longitudinal movement of two trolleys with a tub mounted on them with a transverse beam installed with the possibility of being turned relative to one of them in the plane, perpendicular the longitudinal axis of the installation, with the guide and support rollers mounted on the respective housings of the welding heads, each guide roller is kinematically connected with rollers for welding wire feed. In addition, on the basis of the mounted, parallel-mounted bolster is a rotating comb for fixing the stiffening rings. Figure 1 shows the installation, General view; figure 2 is the same, top view; fig.Z - the same, axonometric; in fig. 4 - winding mechanism; on fig.Z - the same, top view; figure 6 - section aa on fig.Z. The installation comprises mounted on base 1, table (s) 2 for sheet web 3 and mechanism 4 for winding sheet web 3 on stiffening rings 5. The winding mechanism 4 is made in the form of two carriages 6 and 7 with a beam 8 mounted on them, with the beam fixed on one of the carriages hinged and installed with the possibility of rotation from the actuator 9 Regarding the axis of the hinge, in a plane perpendicular to the longitudinal axis of the installation. The beam 8 hinges the welding heads 10 with the roles 11 for supplying the welding wire 12. The installation is equipped with a clamping sheet, which is fixed to the stiffening rings made in the form of a sprung guide roller 13 fixed to the welding head body and the supporting rollers 14, the Guide the roller 13 is connected to the rollers 11 for feeding the welding wire with intermediate brushings 15. On the uprights 16 of the base, parallel to the beam 8, there is a rotating comb 17 for fixing the stiffening rings. Carts 6 and 7 are moved by winches 18 from Caen 1 to 9. 4 The device operates as follows. Sheet sheet (map) 3 of sheet steel is laid out on the plaz 2. The trolleys 6 and 7 of the winding mechanism 4 are moved by winches 19 to the area of the rotary-comb 17 and stop above the drive 9. The drive, abutting against the support bar of the beam 8, makes it one-sidedly lift (turn relative to the trolley 6J. , then the beam is lowered and secured on the trolley 7. The stiffening rings are pressed against the spring-loaded guide roller 13 to the rolled sheet 3. The comb 17 rotates and fixes the upper ends of the stiffening rings in a vertical position. The winches 18 are turned on, By means of the rope 19, they begin to move the winding mechanism 4. The support rollers 14, supported by stiffening rings, begin to roll them around the plaza. At the same time, the guide rollers 13, rolling along the inner surfaces of the rings, are fed through gears 15 and feed welding wire 12 In the zone of welding of rings with rolled sheets rolled over on them 3. The process of simultaneous welding of rings 5 of rigidity and folding of card 3 into a cylindrical body (shell /) begins. . At the end of the welding, the beam 8 is raised by the actuator 9 and the finished cylindrical body is removed. Then the cycle is repeated. The proposed design allows for a continuous mechanized folding process (winding sheet panels and automatic welding of rigidity rings to these panels. In addition, it eliminates the need to preassemble the rigidity rings on a special frame and then disassemble it and the presence of a person in the welding zone. Invention 1. Installation for Assembly and welding of thin-walled cylindrical shells with stiffening rings, containing a table for sheet metal and fur; winding of sheet nn.no titl on stiffener stud, welding head with rollers mounted on it for supplying welding wire, A. pressing the sheet cloth to stiffening rings, made with supporting and guiding rollers, so that , with an increase in productivity and quality of welding by ensuring continuous winding and welding of sheet panels with stiffening rings, the mechanism of sheet winding on stiffening rings is designed as installed on the base with the possibility of longitudinal movement and with two carriages mounted on them transverse beam mounted pivotally relative to one of them in a plane perpendit l purpose cool molecular longitudinal axis of the apparatus, thus, guide and support Po-. The clamping faces are fixed on the respective housings of the welding heads, and each guide roller is kinematically connected with the rollers for feeding the welding wire. 2. Installation pop. 1, which differs from the fact that, on the base parallel to the winding mechanism beam, there is mounted a rotating comb for fixing the stiffening rings.
