Abstract
The invention discloses a machining method of operating mechanism spindle components for circuit breakers and load switches. A spindle and operating blocks of an operating mechanism spindle component are machined according to product requirements. The machined operating blocks are sleeved on the spindle one by one and are placed on a special positioning rack for precision positioning. After two points are fixed by argon arc welding, two surfaces of a joint of each positioned operating block with the spindle are evenly filled with copper-base solder paste by a pressure gun. After filling of the copper-based solder paste, the operating mechanism spindle component is placed on a mesh-belt electric furnace for soldering, wherein ammonia decomposition protecting gas is introduced continuously into the mesh-belt electric furnace and the mesh-belt electric furnace is pushed forward at constant speed. The operating mechanism spindle component machined by the method is smooth, flat and non-deforming and has tensile strength, larger than 250N/mm<2>, meeting the user requirements.
Description
Technical field
The present invention relates to power-supply device process technology, particularly the processing method of a kind of breaker, load switch operation mechanism spindle assemblies.
Background technology
Have operating mechanism in existing high pressure breaker, on-load switch, what particularly power was larger all uses operating mechanism main shaft assembly to drive opening and closing of breaker, on-load switch, and operating mechanism main shaft assembly is one of significant components of device systems.Spindle assemblies is the design attitude at main shaft, is fixed with polylith operating block respectively.Because operating mechanism main shaft assembly is when reality uses, powerful axial impact force and tensile force be born, require that tensile strength is greater than 250N/mm according to user
2, axial shearing force is greater than 62300N.Polylith operating block will drive other corresponding mechanical action simultaneously, and therefore polylith operating block position on main shaft is wanted accurately, and operating block can not be out of shape.Current process operation mechanism spindle assemblies, what main shaft and polylith operating block fixed employing is welding technology, mainly contains Laser Welding, argon arc welding.Because melting welding is office's step molten solder thing, easily produces the phenomenon such as pore, rosin joint, directly affect the intensity of product, be heated during welding uneven yielding, affect product installation quality, general yield rate, below 85%, be improved the quality of products and will have masterful technique workman.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides the processing method of a kind of breaker, load switch operation mechanism spindle assemblies, namely adopt guipure electric furnace brazing technology, the defect easily producing rosin joint, pore, distortion can be overcome.
To achieve these goals, the processing method of a kind of breaker of the present invention, load switch operation mechanism spindle assemblies, comprise the steps: (1) by designing requirement orderly ready-made operating block is packed into main shaft one by one, be placed on special locating rack and accurately locate, 2 points of each operating block and main shaft junction are fixed with argon arc welding, prevent operating block to be shifted, guarantee the exact position of each operating block on main shaft; (2) to the sixth of the twelve Earthly Branches location each operating block and the two sides of main shaft junction, evenly inject copper base pricker cream with pressure gun; (3) the operating mechanism main shaft assembly injected after copper base pricker cream is placed on the guipure electric furnace that at the uniform velocity advances and carries out soldering, with 30 minutes through 60 ~ 900 DEG C of preheating zones, 60 minutes through 900 ~ 1150 DEG C of high temperate zones, within 30 minutes, through 900 ~ 60 DEG C of progressively salbands, complete whole operating mechanism main shaft assembly brazing process.
In above-mentioned steps (2), pressure gun evenly injects copper base pricker cream is red copper base solder paste, can ensure high temperature brazing.
Be connected with ammonolysis craft protection gas when above-mentioned steps (3) guipure electric furnace carries out soldering in guipure electric furnace continuously, prevent product from after high temperature, producing oxidation.The beneficial effect of the preparation method of a kind of breaker of the present invention, load switch operation mechanism spindle assemblies:
With the operating mechanism main shaft assembly that the inventive method makes, smooth, smooth, indeformable, through appliance special for detecting detected intensity, yield rate reaches 100%, and department is detected after testing, and the tensile strength of operating mechanism main shaft assembly reaches 350N/mm
2, axial shearing force is greater than 89000N.
Accompanying drawing illustrates:
Fig. 1 is operating mechanism main shaft modular construction schematic diagram.
In figure: operating block a (1), operating block b (2), main shaft (3), brazed portions (4).
Detailed description of the invention:
Below in conjunction with the enforcement of accompanying drawing to the processing method of a kind of breaker of the present invention, load switch operation mechanism spindle assemblies, be described in further detail.
By main shaft (3) and operating block a (1), the operating block b (2) of the good operating mechanism main shaft assembly of product requirement fine finishining; Orderly packs into main shaft (3) by figure one by one by ready-made operating block a (1) and operating block b (2), be placed on special locating rack and accurately locate, 2 points of each operating block and main shaft junction are fixed with argon arc welding, prevent operating block to be shifted, guarantee the exact position of each operating block on main shaft; Each operating block of locate the sixth of the twelve Earthly Branches and the two sides of main shaft junction brazed portions (4), evenly inject copper base pricker cream with pressure gun; The operating mechanism main shaft assembly injected after copper base pricker cream is placed on and at the uniform velocity advances; be connected with continuously ammonolysis craft protection gas guipure electric furnace on soldering; with 30 minutes through 60 ~ 900 DEG C of preheating zones; 60 minutes through 900 ~ 1150 DEG C of high temperate zones; within 30 minutes, through 900 ~ 60 DEG C of progressively salbands, complete whole operating mechanism main shaft assembly brazing process.
The operating mechanism main shaft assembly of soldering on guipure electric furnace, through appliance special for detecting detected intensity, what reach standard becomes the product that dispatches from the factory.
Claims (1)
1. the processing method of a breaker, load switch operation mechanism spindle assemblies, it is characterized in that comprising the steps: (1) by designing requirement orderly ready-made operating block is packed into main shaft one by one, be placed on special locating rack and accurately locate, fix 2 points of each operating block and main shaft junction with argon arc welding; (2) to the two sides of oriented each operating block and main shaft junction, copper base pricker cream is evenly injected with pressure gun; (3) the operating mechanism main shaft assembly injected after copper base pricker cream is placed on the guipure electric furnace that at the uniform velocity advances and carries out soldering; with 30 minutes through 60 ~ 900 DEG C of preheating zones; 60 minutes through 900 ~ 1150 DEG C of high temperate zones; within 30 minutes, through 900 ~ 60 DEG C of progressively salbands, during soldering, in guipure electric furnace, be connected with ammonolysis craft protection gas continuously.
