Abstract
The utility model relates to a novel average pressure ball comprises a top cover provided with a cover hole, a base provided with a bottom hole and a flange provided with a middle hole, wherein, the radial direction of the flange is provided with a outward convex platform, both sides of which are provided with arc outstretched surfaces; the upper and the lower side faces of the convex platform contact with the side walls of the top cover and the base respectively and are welded on the joint of the top cover, the convex platform and the base. The workload can be reduced because of the design with the above structure. During the making process, the average pressure ball is processed into two haves, the flange is lathed with a convex platform and an arc transition surface, the there parts are integrated as one and welded outside with a burnishing welding scar and burnished, washing, packing. The prior there welding lines are reduced into one welding line, which saves 2/3 welding cost and decreases the difficulty of the technique greatly without doing the inside welding technique.
Description
Technical field
The utility model relates to a kind of structure technology of voltage equalizing ball.
Background technology
Usually when the processing voltage equalizing ball, being earlier voltage equalizing ball to be made loam cake and base two halves when connecting shell and flange,---flange is put in, and------flange is placed on size positions, and------the lathe car removes the crator on flange both sides, and---polishing sanding---cleaning---is packed on the welded flange both sides for the welding shell and the inwall crator of polishing earlier.This method for production, the weld seam intractability is big, takes a lot of work, time-consuming, expense material.
The utility model content
The purpose of this utility model is to invent a kind of novel voltage equalizing ball of convenient welding.
The utility model comprises and is provided with the loam cake that covers the hole, is provided with the base of bottom outlet and is provided with the flange of mesopore, flange radially be provided with outside boss, be provided with the arc extended surface in the both sides of boss, the upper and lower two sides of boss are contacted with the sidewall of loam cake and base respectively, in the welding of the junction of loam cake, boss and base.
Because above-mentioned design reduces workload, when making, voltage equalizing ball is processed into two halves, and---the flange car is gone out boss and arc transiting surface---is three-in-one then, externally welding---polishing crator and sanding---cleaning---packing.Original three road weld seams are economized to one weld seam, can be saved welding cost 2/3, and needn't carry out the welding procedure of the inside, greatly reduce technology difficulty.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 lid hole, 2 loam cakes, 3 flanges, 4 boss, 5 arc extended surfaces, 6 bases, 7 bottom outlets, 8 mesopores.
Specific embodiment
The flange 3 that is provided with mesopore 8 continues at the middle part and radially boss 4, the width of boss 4 can be identical with the wall thickness of loam cake 2, base 6, upper and lower both sides at boss 4 are provided with arc extended surface 5, by boss 4 flange 3 is arranged in 2 of base 6 and loam cakes, and arc extended surface 5 is matched with the inwall of loam cake 2 and base 6 respectively, by welding sequence the three is carried out the crator sanding again after affixed with the outside of base 6 at boss 4, loam cake 4.
Claims (1)
1, novel voltage equalizing ball, comprise and be provided with the loam cake that covers the hole, be provided with the base of bottom outlet and be provided with the flange of mesopore, what it is characterized in that flange radially is provided with outside boss, be provided with the arc extended surface in the both sides of boss, the upper and lower two sides of boss are contacted with the sidewall of loam cake and base respectively, in the welding of the junction of loam cake, boss and base.
