In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only one embodiment of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without any inventive work.
Fig. 1 is a schematic structural diagram of the die structure of the stamping part of the present invention.
In the figure: the device comprises a shearing punch 1, an air blowing device 2, an air blowing hole 3, a pneumatic valve 4, an ejector rod 5, a stripping pin 6, an air flow channel 7, an air passage 8, a stamping part 9 and a material belt 10
Detailed Description
The following further description is made with reference to the accompanying drawings and examples,
as shown in fig. 1, a die structure of a stamping part, including a shearing punch 1, a lower die plate, the shearing punch 1 is fixed in the lower die plate, the die structure further includes a push rod 5, a stripping pin 6, an air flow channel 7 and an air blowing device 2, the position of the air blowing device 2 corresponds to the air flow channel 7, the stripping pin 6 is installed right above the shearing punch 1, the shearing punch 1 punches a strip 10 into a stamping part 9 with consistent burr direction, the stamping parts 9 all fall into the stripping pin 6, an air channel 8 is arranged on the side surface below the stripping pin 6, the height of the air channel 8 is greater than the thickness of the stamping part 9, the push rod 5 is movably installed in the stripping pin 6, and when the push rod 5 downwards pushes down the stamping part 9 in the stripping pin 6, the air blowing device 2 blows the stamping part 9 into the air flow channel 7 through the air channel 8. Because take off material round pin 6 and install directly over shearing drift 1, when shearing drift 1 from bottom to top to work piece (generally adopt material area 10) when punching press, stamping workpiece 9 shaping back, its deckle edge direction is downward and stamping workpiece 9 all falls into takes off in the material round pin 6 to form the stamping workpiece 9 that deckle edge direction is unanimous.
In practical application, in order to make the structure more reasonable, the central line of the ejector rod 5 and the central line of the stripping pin 6 are superposed with the central line of the shearing punch 1, and the weight of the stamping part 9 is generally not more than 50g, so that the air blowing device 2 can smoothly blow the stamping part 9 into the air flow channel 7. In addition, the die structure of the utility model also comprises a stripper plate and a material belt 10, the airflow channel 7 is generally positioned at the bottom of the stripper plate, the stripper pin 6 is positioned in the stripper plate, when the material belt 10 is fixed on the lower template, the stripper plate and the lower template clamp the material belt 10, the shearing punch 1 punches the material belt 10 from bottom to top into a stamping part 9 with consistent burr direction, after the shearing is completed, the stamping part 9 falls into the stripper pin 6, at the moment, the ejector rod 5 can downwards and easily eject the stamping part 9 in the stripper pin 6 (when the ejector rod 5 pushes the stamping part 9 downwards, the gravity of the stamping part 9 is also utilized), when the stamping part 9 falls down, the blowing device 2 can blow the stamping part 9 into the airflow channel 8, because the blowing device 2 continuously blows a large amount of air to the horizontal direction of the stripper pin 6, the airflow is strong, and then blows the stamping part 9 in the airflow channel 8 into the airflow channel 7, therefore, the stamping part 9 is automatically detached from the die, personnel are not needed to participate, the operation is very safe, and the labor cost is also saved.
