Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.

[0065] In order to overcome the collapse problem of the existing blanking die frame structure in the production process, the present invention proposes a blanking die frame structure with a supporting device, which supports the reciprocating movement of the shuttle rod without affecting the normal operation of the die. Under the premise, realize the support of the blanking mold frame when the mold is opened, and prevent the frame from collapsing due to its own gravity, which is applicable to all blanking molds.

Abstract

The invention relates to the field of dies, in particular to a blanking die frame structure. The blanking die frame structure comprises a die base, a frame, a shuttling rod and a push-pull wedge, wherein the shuttling rod is connected with the push-pull wedge, installed in the die base and located directly below a frame component; the push-pull wedge is fixed on the side surface of the die base and is positioned outside the frame; when a die is in an open state, the push-pull wedge moves to a retreating position, the shuttling rod is driven to move synchronously, and the shuttling rod is attached to the frame to provide support for the frame; and when the die is in a closed state, the push-pull wedge moves downwards to a push-out position along with a press sliding block, the shuttling rod is driven to move synchronously, the shuttling rod is separated from the frame, and supporting to the frame is relieved. According to the blanking die frame structure provided by the invention, the collapse problem caused by the dead weight of the frame in the stamping production process is solved, and the blanking die frame structure is suitable for all blanking dies and is simple in mechanism principle, compact in structure, stable in operation, low in cost and high in reliability.

Description

technical field [0001] The invention relates to the field of molds, and more specifically relates to a blanking mold frame structure. Background technique [0002] The blank frame is the main working part in the blanking die, and its main function is to provide support for the coil transmission: [0003] When the mold is opened, the nitrogen spring under the frame lifts up the frame, so that the coil material is separated from the cutting edge; [0004] When the mold is closed, the pressing block of the upper mold presses down the frame and separates it from the coil material. [0005] Blanking is completed by edge trimming knife, the position and quantity of the pressing block of the upper die and the nitrogen spring of the lower die must be exactly the same, otherwise the frame will be deformed due to partial load. [0006] The pressing block of the upper mold and the nitrogen spring of the lower mold can only be located on both sides of the coil material transmission di...
