Abstract

The invention discloses a flanging hole machining die device. The flanging hole machining die device comprises a positioning sleeve and a hole drilling and flanging mandrel, wherein the hole drilling and flanging mandrel penetrates through the positioning sleeve; a conical spiral guide sleeve is connected to the hole drilling and flanging mandrel; a hole drilling and flanging positioning piece is connected to the conical spiral guide sleeve; two sets of flanging pins are connected to the two sides of the hole drilling and flanging positioning piece through two sets of screws respectively; a hole drilling and flanging adjusting guide sleeve is arranged in the positioning sleeve; an axial block is connected to the hole drilling and flanging adjusting guide sleeve; a hole drilling and flanging mandrel sheet is arranged on the hole drilling and flanging mandrel; a disc type spring sheet is arranged on the hole drilling and flanging mandrel; and a fixing needle is arranged on the disc type spring sheet. According to the flanging hole machining die device, a conical spiral principle is utilized, and a conical spiral groove is driven by rotation, so that a flanging hole can be machined at one time, the production efficiency is increased, the appearance is uniform, and the quality is stable.

Description

technical field [0001] The invention relates to the technical field of flanging hole processing, in particular to a flanging hole processing mold device. Background technique [0002] At present, when the refrigeration pipe fittings in the refrigeration system are connected to the branch pipe, in order to increase the contact surface and welding strength of the weld, the hole welded with the branch pipe needs to be processed into a flanged hole structure; the traditional flanged hole processing method is A pre-drilled hole is processed first and then drawn into a flanging hole structure. The production efficiency is slow and the appearance of the processed flanging hole is not uniform. [0003] Based on this, the present invention designs a flanging hole processing mold device to solve the above-mentioned problems. Contents of the invention [0004] The purpose of the present invention is to provide a flanging hole processing mold device, using the principle of conical sp...
