Auxiliary device for welding of large ironware

Abstract

The invention discloses an auxiliary device for welding of large ironware. The auxiliary device comprises a side frame, a truss is horizontally welded to the side frame, and a water cooling assembly and a limiting assembly are respectively arranged on the truss. According to the auxiliary device, a collector filled with cooling liquid is arranged below the truss, the collector is used for providing movable support for a bearing rod and a bearing table, a rotating transmission gear is used for being in engaged connection with a driving rack and a driven rack, the driven rack and a driving piston move upwards, and a limiting clamping plate is further promoted to horizontally move so as to clamp and limit a to-be-welded object; and the collector slidably provided with the bearing rod and a high-pressure piston in a sleeving mode is arranged, a cooling sleeve is mounted through a discharging pipe and a backflow pipe, thus the cooling liquid in the collector enters the cooling sleeve under the action of heavy pressure, it is ensured that the heated cooling liquid can directionally flow in the collector and the cooling sleeve, thus the periphery of the to-be-welded object is subjected to low-temperature conduction, the circumstance that the to-be-welded object is in a high-temperature state overall is avoided, and cooling shaping of the welding position of the to-be-welded object can also be accelerated.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an auxiliary device for welding large pieces of ironware. Background technique [0002] The progress of the economic level is inseparable from the development of heavy industry. Heavy industry is the industry that provides the main means of production for the material and technological basis of various sectors of the national economy, mainly including iron and steel industry, metallurgical industry, machinery, energy (electricity, petroleum, coal, natural gas, etc.) It provides raw materials, power, technical equipment and other labor materials and labor objects for various departments of the national economy (including industry itself), and is the material basis for realizing social reproduction and expanded reproduction. [0003] As the most common raw material and object of action in heavy industry, ironware has always played an important role. With the needs of the developm...
