Flanging die for non-standard hole of air conditioner fin

Abstract

The invention relates to a flanging die for a non-standard hole of an air conditioner fin. The die comprises an upper part and a lower part, a limiting column is arranged between the upper part and the lower part, all parts of the die are connected through screws and pins, a die guide device comprises a guide column and a guide sleeve, and a die hoisting device comprises a lifting bolt; and the upper part comprises an upper die base, an upper wedge block, baffles and a horizontal baffle. The lower part comprises a lower die base, an outer wedge block, an outer stop block, a sliding plate, an inner wedge block, a male die, an outer female die, an inner female die, an ejector, a push plate and an inner stop block, and through machining testing and improvement of a thin-wall air conditioner fin cylinder sheet metal part, the whole flanging die is perfected. The problems of low workpiece quality and low efficiency caused by traditional single-hole flanging forming are solved.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a flanging mold for non-standard holes of air-conditioning fins. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] Flanging refers to the forming method of forming a straight wall or flange with a certain angle along the closed or unclosed curved edge on the flat part or curved part of the blank by using the function of the mold. Hole turning is a forming method of turning the material into a side flange along the inner hole. The existing flanging molds fo...

AI Technical Summary

Problems solved by technology

The existing flanging molds for special-shaped holes need to perform hole turning and flanging operations on the workpiece. Specifically, the internal turning operation is performed on the workpiece first, because it is more convenient to process from the inside to the outside, and it is not easy to be damaged. Turning the hole After finishing, the flanging operation is being carried out; through the step-by-step operation, there are shortcomings: 1. Two sets of molds need to be prepared, which increases the cost, and the two-step operation is complicated, which is not conducive to fast and efficient production; 2. From the inside Distributing operations outside will result in a decrease in accuracy and will be easily damaged during the production process, which is not conducive to product standardization and unification
