Punching die for louver slat

Abstract

The invention discloses a punching die for a louver slat. The punching die comprises a static die A, a static die B and a die punching assembly, the die punching assembly is arranged in the die punching storing space in the static die B, the die punching assembly comprises a punching cutter, a fixed module and a moving module, the fixed module is fixedly arranged at the upper part of the punchingcutter through a pin shaft, the moving module is slidably arranged in the limiting groove in the lower part of the punching cutter through a pin shaft, and a plurality of resetting springs are furtherarranged between the fixed module and the moving module. Compared with the prior art, when a punching device controls the punching cutter to conduct punching on the wooden slat, firstly, the moving module keeps contact with and compresses the slat, the punching cutter overcomes the resistance of the resetting springs and reaches the upper surface of the slat for further punching of a rope penetrating hole during downward recompressing until punching is completed, the moving module makes the slat be in compressed state in the whole process, edge collapsing and position offsetting of the rope penetrating hole of the slat are prevented, the structure is simple, and practicability is high.

Description

technical field [0001] The invention belongs to the field of curtain supplies, and in particular relates to a punching die for a venetian curtain sheet. Background technique [0002] In the field of venetian blinds, wooden curtains are often used in curtain curtains, but rope holes need to be punched on wooden curtains. At present, when the curtains are punched with rope holes, the punching device is directly used to control the punching knife to place on the static mold. Wooden curtains are used for punching operations. Long wooden curtains are generally not fixed and positioned, and they are easy to shift when punching. When punching, it will cause edge collapse around the rope hole and hole position deviation. At the same time, the current industry uses The problem of setting the position of the punching knife edge is generally only to set the V-shaped incision in the horizontal direction of the knife edge. If the curtain is placed slightly uneven, it will cause uneven fo...

Wooden curtains are used for punching operations. Long wooden curtains are generally not fixed and positioned, and they are easy to shift when punching. When punching, it will cause edge collapse around the rope hole and hole position deviation. At the same time, the current industry uses There is a problem with setting the position of the punching knife edge. Generally, only the V-shaped incision is set horizontally on the knife edge. A slight unevenness in the placement of the curtain will also lead to uneven force and edge collapse when the rope hole is punched.
