Product Description

Fin Die

1.Fin Die Features:
The Fin Die is an independent sub-unit from the the large mold base, where the blade-edge unit has an independent guide column and guide sleeve.
Each processing step as follow:
1.1) Drawing unit: According to the calculated data, a certain height and diameter convex hull is pre-drawn on the strip material. Among them, each channel has an independent adjustment device, and a position display indicator can record the corresponding number of adjustment heights of the channel punch for later convenient adjustment.
1.2) Louver forming unit:Flush the louver-type crack on the strip material as required by the fin scheme. The unit has an independent guide column and guide sleeve to ensure reasonable clearance between the upper and lower molds.
1.3) Punching flanging unit: flipping out the straight edge and the electro-thermal hole on the strip material with punched convex hull. The unit has an independent guide column and guide sleeve to ensure reasonable clearance between the upper and lower molds.
1.4) Double Flanging unit: On a flanging cylinder, turn the straw hat outward. There is an independent adjustment device, and a position display indicator can record the corresponding number of adjustment heights of the flanging of the track.
1.5) Slitting unit: Use three screws to adjust the position of the upper knife to determine the number of rows of the slits.
The unit has an independent guide column and guide sleeve to ensure reasonable clearance between the upper and lower molds.
1.6) Embossing unit: Pressing the fin edge pattern. Adjust the knife position with three screws to determine the number of rows of embossing.
1.7) Feeding unit: There is a small claw raised into the fin mouth to pull the strip forward one step.
1.8) Leveling unit:
1.9) Cutting unit: Cuts the strip material in accordance with the preset number of holes.
The above units are assembled in a large formwork to ensure the relative position of each unit.
