Abstract
The invention discloses a front and rear pilot mechanism for a longitudinally cutting die. The mechanism comprises upper and lower longitudinally cutting fixing plates which are fixed with upper and lower longitudinally cutting cutters respectively, wherein the upper longitudinally cutting fixing plate is provided with front and rear pilot male dies on two sides of the upper longitudinally cutting cutter; front and rear pilot female dies which are matched with the front and rear pilot male dies are arranged on the lower longitudinally cutting fixing plate; and a fixed stripper plate is arranged above the front and rear pilot female dies. The front and rear pilot mechanism for the longitudinally cut mold is provided with the front and rear pilot male dies on the upper longitudinally cutting fixing plate and the front and rear pilot female dies which are matched with the front and rear pilot male dies on the lower longitudinally cutting fixing plate, and combines the front and rear pilot and longitudinal cutting in a pair of sub-die. Therefore, the front and rear pilot mechanism has the advantages of capacity of reducing accumulated errors of processing and assembling, simple structure, easy implementation and high pilot accuracy.
Description
Technical field
The present invention relates to a kind of mould structure, particularly relate to a kind of front and rear pilot mechanism for longitudinally cutting die.
Background technology
At present, air-conditioner fin die is a kind of high-accuracy cold punching progressive die of special production air-conditioner fin, air-conditioner fin is exactly the fin that is used for heat exchange in air-conditioning, most fin material is aluminium and copper, traditional longitudinal cutting structure just is provided with the correcting structure in the rip cutting front, and the back does not have, and correcting structure and longitudinal cutting structure are to be installed separately on large form, this correcting structure Design can't be carried out accurate correcting to material, tend to make the product both sides owing to rip cutting cross cut produce burr and long must, and then have influence on the performance and the outward appearance of product.
Summary of the invention
The object of the present invention is to provide a kind of front and rear pilot mechanism for longitudinally cutting die, it has simple in structure, is easy to realize; The characteristics that the correcting precision is high.
The objective of the invention is to be achieved through the following technical solutions:
A kind of front and rear pilot mechanism for longitudinally cutting die, it comprises the rip cutting upper and lower fixing plate that is fixed with the upper and lower cutter of rip cutting respectively, wherein, described rip cutting upper mounted plate is provided with forward and backward correcting punch in the both sides of top slitter, cooperate forward and backward correcting punch to be provided with forward and backward correcting die in the rip cutting bottom plate, described forward and backward correcting die top is provided with positive stripper.
The upper and lower cutter of described rip cutting is fixed on the rip cutting upper and lower fixing plate by the upper and lower cutter fixed block of rip cutting, and the top of described top slitter fixed block is provided with cushion block.
Described top slitter fixed block is fixed on the top slitter fixed head by fixed screw.
Beneficial effect of the present invention is, described front and rear pilot mechanism for longitudinally cutting die is provided with forward and backward correcting punch in the rip cutting upper mounted plate, cooperate forward and backward correcting punch to be provided with forward and backward correcting die in the rip cutting bottom plate, and front and back correcting and rip cutting are combined in the secondary submodule, can reduce the accumulated error of processing, assembling, not only simple in structure, be easy to realize; And correcting precision height.
