Embodiment 1

[0015] Embodiment 1: ① Carry out fine punching to the baffle. Such as figure 1 As shown, the edge 2 of the baffle 1 is tilted upwards in a "[" shape, and a nozzle 3 is provided on the baffle. Keep the hole spacing and relative position of each hole consistent.

[0016] ②Inner core assembly. The finned tube single tube and the baffle are assembled into one body with the inner core assembly equipment, which can effectively guarantee the accuracy requirements of the assembly size. Such as figure 2 As shown, the front and rear ends of the tube 4 with steel fins are installed in the nozzle 3 of the baffle 1 respectively, and the baffle at the front end is placed on the table top 5 and is blocked by a fixed block 6 arranged on the table top. A fixed plate 7 is arranged on the desktop, and a hole is arranged on the fixed plate, and the shaft 8 passes through the hole, the shaft can rotate in the hole, and the shaft can also be fixed by the bearing; the rear end of the shaft is a...

Abstract

The invention discloses an automatic welding process and tooling of an orifice and a header of a radiator of a steel-made fin tube, relates to the manufacturing of a radiator and includes the sequential processes: (1) performing fine punching of a baffle; (2) inner core assembly: assembling a single pipe of the fin tube and the baffle into one body with an inner core assembly device; (3) automatic welding: the inner core of which the tube and the orifice are initially welded is fixed by an automatic welding fixer of the orifice and welded through a tri-axial numerical control welding torch; (4) location initial welding of the header: the inner core of which the tube and the baffle are completely welded is hung on an initial welding scaffold, and the header is positioned through a header positioner and then the welding torch is used for the initial welding of the header; (5) automatic header welding: the inner core of which the header is welded initially is hung on the welding scaffoldthrough a hanging column and is welded through the tri-axial numerical control welding torch. The process and tooling are remarkable in effect, stable in quality and can improve the good quality rateby more than 30 percent; the work efficiency can be improved and one set of machine can finish the work load equivalent to that of 8 people.

Description

Technical field: [0001] The invention relates to the manufacture of radiators, in particular to the welding process and device of steel finned tube radiators. Background technique: [0002] At present, the products of steel finned tube radiators are all manually operated. The parts are assembled into groups and welded by manual arc welding. Due to too many human factors in this process, the welding quality is unstable and the work efficiency is low. Invention content: [0003] The invention aims at the defects of unstable welding quality and low work efficiency of manual arc welding of steel finned tube radiator products, and utilizes mature CO 2 The shielded welding process and the three-axis CNC automatic operation welding torch device realize the automatic welding of the steel finned tube radiator nozzle and header, with stable quality and improved work efficiency. [0004] The object of the present invention is achieved by the following scheme: a steel finned tube rad...
