Technical Field

[0001] The utility model relates to the technical field of precision stamping dies, in particular to an automatic part-taking mechanism for precision stamping dies. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: after the stamping is completed, the existing precision stamping die needs to be manually removed from the inside of the cavity. Due to the friction between the stamping part and the inside of the cavity, the stamping part is difficult to remove, which affects the efficiency of removing the stamping part; therefore, in order to solve the above problem, an automatic removal mechanism for precision stamping dies is proposed.

[0007] Preferably, a limiting groove is provided on the side of the through hole, and a limiting block is fixedly installed on the surface of the push rod, and the limiting block is adapted to the size of the limiting groove.

[0008] The effect achieved by the above components is: by setting the limit groove and the limit block to cooperate with each other to limit the push rod, the push rod is prevented from being stored in the inside of the through hole, causing the top of the push rod and the top of the through hole to be not at the same level, affecting the stamping effect of the stamping part.

[0009] Preferably, second springs are fixedly mounted on both sides of the top of the connecting plate, and the top of the second spring is fixedly connected to the bottom of the bottom plate.

[0018] The utility model provides a punching cylinder to drive the punching head to move downward, so that the punching head punches the punching part inside the punching die, and provides a first spring to bounce the punching head upward for reset. When the punching head completes the punching, the side plate presses the second push switch, so that the second push switch controls the punching cylinder to close, so that the punching head moves up and resets under the elastic force of the first spring. The first push switch and the extrusion column cooperate with each other to control the opening of the picking cylinder. When the punching head moves upward after the punching is completed, The side plate drives the extrusion column to move upward, so that the extrusion column squeezes the first push switch, and then the first push switch controls the picking cylinder to open. The picking cylinder is set to drive the connecting plate to move upward, and the connecting plate drives the push rod to move upward, so that the push rod pushes out the stamping parts inside the stamping die, thereby facilitating the removal of the stamping parts. At the same time, it solves the problem that after the stamping is completed, the existing precision stamping die needs to manually remove the stamping parts from the cavity. Due to the friction between the stamping parts and the inside of the cavity, the stamping parts are difficult to remove, which affects the efficiency of taking out the stamping parts.

An extrusion column 13 is fixedly installed on the top of the side plate 8, and the top of the extrusion column 13 is against the first push switch 12. Through holes 15 are provided on both sides of the bottom of the inner cavity of the stamping die 7. A mounting frame 18 is fixedly installed on the bottom of the base plate 1, and a pick-up cylinder 19 is fixedly installed on both sides of the inner side of the mounting frame 18.
