Continuous progressive die for waisted type cooling fin

Abstract

The invention belongs to the technical field of die structures, and provides a continuous progressive die for a waisted type cooling fin. The continuous progressive die comprises a die hold assembly,a feeding assembly, a punching assembly, a flanging guide assembly and a discharging assembly, wherein the feeding assembly, the punching assembly and the flanging guide assembly are sequentially arranged in the length direction of the die holder assembly; the die holder assembly comprises a first die assembly and a second die assembly which are oppositely arranged; the punching assembly comprisespunching female die bodies and first punch parts, wherein the female die bodies are arranged on the first die assembly, and the first punch parts are connected to the second die assembly; the flanging guide assembly comprises flanging female die bodies and second punch parts, wherein the flanging female die bodies are arranged on the first die assembly, and the second punch parts are used for flanging openings punched by the punch parts; the first punch parts are in the shape of a ladder; the front end surfaces of the first punch parts are arc-shaped; and guide parts are further arranged at the front end parts of the second punch parts. The continuous progressive die has the advantage that by means of the design, the problems that an existing die structure cannot realize continuous production, and meanwhile, the production efficiency is low due to the fact that the design of a punch structure is incomplete can be solved.

Description

technical field [0001] The invention belongs to the technical field of mold structures, and in particular relates to a waist-retracting heat sink continuous progressive mold. Background technique [0002] The waist heat sink is the core part of the car air conditioner. The car air conditioner factory developed the waist heat sink in order to improve the cooling effect of the air conditioner. The waisted heat sink is used for the core parts of the car air conditioner, and the thickness of the single heat sink is only 0.07mm, the width is 16mm or 24mm, and the length is in the range of 300-500mm. The maximum stamping speed of the mold can reach 250 times / min , The punch and die gap is 0.005mm. Furthermore, the mold requirements for the production of heat sinks are relatively high. The traditional mold structure punch structure is not strong enough, and the hole pattern after punching is unstable, which makes it difficult to stack heat sinks and install flat tubes. In addition...
