Embodiment Construction

[0010] Referring to the accompanying drawings, a method for rapid flanging of a casing includes the following steps:

[0011] a, make the flanging mold, the flanging mold includes an upper template 3, a lower template 7, the upper template 3, the lower template 7 are respectively equipped with a corresponding upper flanging punch 4, a lower flanging punch 8, and an upper template 3, a guide sleeve 5 is fixedly installed on the lower template 7, and a guide post 6 that guides and cooperates with the guide sleeve 5 is fixedly installed on the lower template 7. Set, the upper flanging punch and the lower flanging punch have arc transition surfaces; the lower template 4 is fixed with a limit column 2;

[0012] b. First put 9 sets of sleeves to be assembled on the lower flanging punch 8, then place 1 set of tubular workpieces outside the sleeve 9 that needs to be flanged, start the press to drive the upper template and the upper flanging convex The mold moves downward, and the upp...

Abstract

The invention discloses a quick flanging method of a casing, which comprises the following step of: a, manufacturing a flanging mold, wherein the flanging mold comprises an upper mold plate, and a lower mold plate; an upper flanging convex mold and a lower flanging convex mold corresponding to the lower flanging convex mold are mounted on the upper mold plate and the lower mold plate respectively, guide sleeves are fixedly mounted on the upper mold plate, guide columns matched with the guide sleeves are fixedly mounted on the lower mold plate, the upper flanging convex mold and the lower flanging convex mold are sleeved with the internal apertures of the two ends of the casing respectively, and provided with arc transitional surfaces, and limiting columns are fixed on the lower mold plate. With the adoption of the method, the flanging molding of the casing is quick, the flanging effect is good, the assembling rejection rate is decreased, and the quick flanging method is suitable for mass assembling; and with the adoption of the structure, the work efficiency is improved, the product quality is ensured, and the scrap rate is decreased.

Description

technical field [0001] The invention relates to the field of flanging forming, in particular to a method for quickly flanging a casing. Background technique [0002] Many tubular workpieces processed by machinery factories need to be equipped with a sleeve, and the two ends of the sleeve must be flanged to be fixed with the tubular workpiece. At present, in the production process, there is no special flanging tool and suitable assembly method for assembling between the tubular workpiece and the casing, and the scrap rate is high. Contents of the invention [0003] The purpose of the present invention is to provide a method for fast flanging of casing, which is fast in forming the flanging of the casing, has good flanging effect, reduces assembly waste rate, and is suitable for mass assembly. [0004] Technical scheme of the present invention is as follows: [0005] A method for quick flanging of a casing, comprising the following steps: [0006] a. Make the flanging...
