Air conditioner fin cold-punching die capable of preventing waste material jumping

Abstract

The invention discloses an air conditioner fin cold-punching die capable of preventing waste material jumping. The air conditioner fin comprises a base, a lower female die is arranged over the top of the base, and supporting rods are fixedly connected to the two sides of the base respectively; a guiding plate is fixedly connected to the tops of the supporting rods, a first installing hole penetrating through the guiding plate is formed in the top of the guiding plate, and a guiding block is slidably installed in the first installing hole; a connecting block is fixed to the top of the guiding block, an upper male die is fixed to the bottom of the guiding block, a connecting plate is fixedly connected to the outer side of the end, close to the upper male die, of the guiding block in a sleeving mode, two first springs are fixed to the bottom of the connecting plate, a material pressing plate is fixed to the bottoms of the first springs, and an exhaust fan is fixed to the end, close to the base, of each supporting rod. According to the air conditioner fin cold-punching die capable of preventing waste material jumping, through cooperative use of the structures such as L-shaped rods and second springs, waste materials attached to the upper male die can be scraped off, and the condition that the punching work is influenced due to the fact that the upper male die brings out of the waste materials is avoided.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to an air-conditioning fin cold stamping die for preventing jumping waste. Background technique [0002] Stamping die is a special process equipment for processing materials into parts in cold stamping processing, called 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] At present, in the stamping process of air-conditioning fins, due to the small punching holes and punches, it is easy to skip waste during the stamping process, and cause a large number of defective products, which affects the progress of mass production. At the same time, during the return process of the punch, waste materials are easily adsorbed at the bottom of the punch, and will be taken out of the punching hole as the punch...
