Abstract
The present invention relates to a kind of capacitor flange and manufacture method thereof.Existing capacitor flange adopts common process manufacture, no matter mechanical strength, and profile radian and brightness are short of all to some extent, and assembly reliability is poor when connecting capacitor, and sealing is not good.Pin of the present invention is characterized in that forming centre bore by ring wall, and the upper end of described ring wall forms the umbrella shape edge be connected with ring wall one, and described umbrella shape marginal center forms arc convex.The manufacture method of capacitor flange, first descends blank, then to blank central punch, trimming, utilize punch press and grinding tool punch forming, punching course divides four-stage, carries out annealing operation after shaping, and shaping after annealing, cleans after shaping, finally pack shipment.The present invention adopts exclusive processing technology to process capacitor flange, and technical process is simply efficient, the drain pan of the flange energy precision-matched capacitor made, and connection reliability is good, assembles fasteningly not easily to be subjected to displacement.
Description
Technical field
The present invention relates to a kind of capacitor flange and manufacture method thereof.
Background technology
Existing capacitor flange adopts common process manufacture, no matter mechanical strength, and profile radian and brightness are short of all to some extent, and assembly reliability is poor when connecting capacitor, and sealing is not good.
Summary of the invention
The present invention is directed to the defect that prior art exists, a kind of capacitor flange and manufacturing process thereof are provided, effectively promote the mechanical strength of capacitor flange, and good with capacitor matching connection degree, sealing is good.
For this reason, the present invention takes following technical scheme: a kind of capacitor flange, it is characterized in that forming centre bore by ring wall, and the upper end of described ring wall forms the umbrella shape edge be connected with ring wall one, and described umbrella shape marginal center forms arc convex.
The outward-dipping extension in outer end at described umbrella shape edge.
The manufacture method of above-mentioned capacitor flange, first descend blank, again to blank central punch, trimming, utilizes punch press and grinding tool punch forming, punching course divides four-stage, stamping pressure is respectively 35 tons, 25 tons, 25 tons, 5 tons, carries out annealing operation after shaping, shaping after annealing, clean after shaping, finally pack shipment.
Be annealed into vacuum annealing, annealing temperature is 1000-1200 DEG C.
The present invention adopts exclusive processing technology to process capacitor flange, and technical process is simply efficient, the drain pan of the flange energy precision-matched capacitor made, and connection reliability is good, assembles fasteningly not easily to be subjected to displacement.Owing to adopting the Sheet Metal Forming Technology punch forming in 4 stages, mechanical strength is stronger, and adopt vacuum annealing operation be convenient to shaping and promote intensity, stainless steel reduction degree is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of invention
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Capacitor flange as shown in Figure 1, forms centre bore 2 by ring wall 1, and the upper end of ring wall 1 forms the umbrella shape edge 3 be connected with ring wall 2 one, forms arc convex 4 in the middle part of umbrella shape edge 3.The outward-dipping extension in outer end at umbrella shape edge 3.
The manufacture process of above-mentioned capacitor flange is as follows: adopt stainless steel blank, to blank central punch, and trimming, utilize punch press and grinding tool punch forming, punching course divides four-stage, and stamping pressure is respectively 35 tons, 25 tons, 25 tons, 5 tons, carries out annealing operation after shaping, shaping after annealing, clean after shaping, finally pack shipment, be annealed into vacuum annealing, annealing temperature is 1000-1200 DEG C, is preferably 1050 DEG C.
It needs to be noted, the mode of above-described embodiment is only limitted to describe embodiment, but the present invention is confined to aforesaid way incessantly, and those skilled in the art can modify accordingly without departing from the scope of the present invention easily, therefore scope of the present invention should comprise disclosed principle and the maximum magnitude of new feature.
