Problems solved by technology

However, it is not applicable to certain types of punching devices (such as those applied to lead frames), because: in order to avoid splashing of waste materials, the punches of this type of punching device and the through holes on the die are structures that match the shape. There is no extra space in the assembly structure. If a gas device is installed on the cutting edge of the punch, the punch cannot be punched at the position where the gas device is installed, resulting in incomplete punching.
In addition, in order to solve this problem, there is another solution: install a suction device under the blanking of the entire mold, and the blanked waste is completed by negative pressure, so as to solve the difficulty of blanking the small waste of the lead frame trimming. problem, but this method has a large working power and requires additional large auxiliary equipment, resulting in high production costs

Embodiment 1

[0024] refer to Figure 1 to Figure 5 As shown, a preferred punching device provided in this embodiment includes: a punch 20, a stripping plate 30, a die 40, and the punching edge of the punch 20 is provided with a ventilation groove 201 with a length of L. , the stripper plate 30 and the die 40 are provided with a stripper plate through hole 301 and a die through hole 401 matching the shape of the punch, and the side of the stripper plate 30 to the position of the stripper plate through hole 301 is provided with a The air channel 302 corresponding to the ventilation groove 201 of the punch 20, the thickness of the discharge plate 30 is H, and the distance from the air channel 302 to the bottom surface of the discharge plate 30 is h, then the length L of the ventilation groove 201 satisfies h≤L≤H .

[0025] In this embodiment, the length L of the ventilation groove 201 satisfies h≤L≤H, so as to ensure that during the punching operation, the airflow of the air passage 302 blow...

Embodiment 2

[0031] In this embodiment, the structure of the punch 20 and the die 40 is the same as that of the first embodiment, the only difference is that the inlet of the air channel 302 of the discharge plate 30 of this embodiment is located on the upper surface of the discharge plate 30, During the punching operation, the gas of the gas device enters through the inlet of the air passage 302 on the upper surface of the unloading plate 30, and the air flow of the air passage 302 flows to the ventilation groove 201 of the punch 20, and then is guided to the die by the ventilation groove 201 In the direction of the through hole 401 , after the cutting product 10 is punched, its waste 101 is blown out of the through hole 401 of the die under the drive of the airflow.

[0032] In this embodiment, the inlet of the air passage 302 of the unloading plate 30 is arranged on the upper surface of the unloading plate 30, which can shorten the time for setting the air passage 302 when the through ho...

Abstract

The invention relates to a punching device which is simple and convenient to operate, low punching waste drop rate and low in production cost. The punching device comprises a convex die, a concave die and a discharging plate, wherein an air channel is formed in the side surface of the discharging plate; a vent groove is formed in a punching cutting edge of the convex die; high-pressure of the air channel flows into the vent groove of the punching cutting edge of the convex die and is guided by the vent groove to be discharged by a through hole of the concave die during operation of punching; when the high-pressure air is discharged, the punched waste is pushed to drop smoothly. The punching device is high in waste drop rate, simple and convenient to operate and low in production cost.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a punching device with simple operation, high drop rate of small punching waste and low production cost. Background technique [0002] The existing punching device generally includes a frame, a conveying mechanism, a die, a punch and a lifting control mechanism for the punch, the size and shape of the punch match the size and shape of the die, and the conveying mechanism and the die are installed on the machine. On the rack, the punch is above the die and connected with the punch lifting control mechanism. The function of the punch lifting control mechanism is to drive the punch to move up and down, usually powered by an electric motor, a hydraulic cylinder or an air cylinder. Usually the above-mentioned punching device is also equipped with a guide mechanism, which can guide the position of the punch and the die to close the die accurately. The guide mechanism generally includes a guid...
