Abstract

The invention discloses a bending die structure, and relates to the field of die forging. Aiming at the problems that an existing bending die structure is large in tonnage, and when a blank is bent, cracks are easily generated on the surface by galling, and a finished product is inconvenient to take after the blank is bent, the following scheme is proposed that: the structure comprises a main oilcylinder, a first extrusion rod is fixedly mounted at one end of the main oil cylinder, a bending lower die is fixedly mounted at the end, away from the main oil cylinder, of the first extrusion rod,the bending lower die is arranged in an extrusion box, a bending upper die is fixedly mounted on the side, away from the bending lower die, of the extrusion box, a feeding port is formed below the end, close to the bending lower die, of the bending upper die, and an ejector plate is arranged below the feeding port. The bending die structure is novel in structure, manual discharging is omitted, itis avoided that a finished product is not easy to take down after being bent, and the problems that the bending die is large in structure tonnage, cracks are prone to being generated on the surface ofa bent blank due to galling, and the finished product is inconvenient to take down after the blank is bent are solved.

Description

technical field [0001] The invention relates to the field of die forging, in particular to a bending die structure. Background technique [0002] The mold of the bending machine is a tool used by the bending machine to form and process the sheet material. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the shape of the item through the change of the physical state of the formed material. The processing is used to make the blank into a tool with a specific shape and size under the pressure of the bending machine. The bending die refers to the punching die that bends the blank or semi-finished product into a certain shape. The structure of the bending die is the same as that of the general The structure of the punching die is similar, and it is divided into upper and lower parts. It is composed of convex and concave dies, positioning, unloading, guiding and fasteners, etc., but the bending die has its own characterist...
