Description

(54) STAND FOR ASSEMBLING UNDER WELDING SHEET

TOTAL

one

The invention relates to a device for butt welding of sheet panels used in chemical and petroleum engineering, boiler building, etc.

A stand for assembling sheet panels for welding, comprising support drive rollers mounted on the base for transporting panels and a flux feeder with a lifting mechanism made in the form of a tray 1 mounted on the bracket.

The disadvantage of such a stand is that in the case of production of a large nomenclature of panels from different steel grades with high mechanization of all auxiliary operations, manual change of flux in flux streamers reduces the plant capacity, i.e., limits its technological capabilities.

The purpose of the invention is to increase productivity by ensuring the welding of panels of various materials.

This goal is achieved by the fact that in a stand for assembling sheet panels for welding, containing support drive rollers mounted on the base for transporting panels and a flux liner

With its lifting mechanism, made in the form of a tray mounted on the bracket, the flux layer is provided with an additional bracket and tray, and the lifting mechanism of both trays is made as mounted on the base with the possibility of reciprocating movement of the water trolley with axles fixed on it. two drive tg and trolleys mounted on each axle on both sides of the longitudinal axis of the device are two hinged double-arm levers, one shoulder of each of which is fixed on the brackets, the tray, and the other on wate r t.

Claims (1)

The stand for assembling the sheet metal for welding contains a horizontal beam 1, along the guides of which the welding unit 2 moves, mounted on the base of the support-drive rollers 3 for transporting the panels from one working place to another for welding the joints and flux cushion 4, made as separate trays 5 and 6 located in the working position in different horizontal planes. The trays with brackets 7 are mounted on double-arm levers 8, set in pairs on axis 9. The axles are fixed in supports 10 of the frame of the trolley 11 and rigidly connected with hinge pins 12 moved by means of pneumatic cylinders 13. The trolley 11 has reciprocating motion relative to the joint a strictly fixed value equal to the center-to-center distance of the flux sheet trays, which is achieved by installing adjustable stops 14. The movement of the trolley is carried out using a cable system 15. The proposed stand works as follows. The assembled floor 11, 1, e is transferred by the rollers 3 and is stopped so that the joint. Kd VI And oU1 J 1 and G1C1 Dvl ri UCJ- 1. Д 1 LJ, I. . . s . -l prepared for welding, was placed above the opening for the flux feeder 4. Flux streams 6 and 5 are filled with fluxes of different brands. Depending on the destination, the carriage 11 is moved to the left or to the right of the adjusted stops 14, while the trays are in the lower position. With one of the pneumatic cylinders 13, through a hinge rod 12 and two shoulders levers 18, one of the trays with a flux and fire is lifted to the junction of the cloth. The welding unit is welding the joint. At the end of welding, the flux tray is lowered using the same pneumatic cylinder and the same system of levers. The proposed stand allows welding of the panels in case of changing the hoist types and the need to use different flux types without stopping the operation of the inertial line operating in the automatic cycle. Invention Stand for assembly for sheet welding -, -. ... . panels containing base-mounted drive rollers for transporting panels and a flux layer with a lifting mechanism made in the form of a tray mounted on the bracket, characterized in that, in order to increase productivity by providing welding of panels of various materials, the flux cushion is provided with an additional a crate tray, and the lifting mechanism of both trays is designed as mounted on the base with the possibility of reciprocating movement of the drive carriage with two axle gears attached to it, and trolleys mounted on each axle on both sides of the longitudinal axis of the device of two double-arm double-arm levers, one shoulder of each of which is fixed on the bracket of the tray, and the other on the drive one.
