Description

A blanking forming device

technical field

The utility model belongs to the technical field of moulds. the

Background technique

Nowadays, molds are often used to manufacture parts with regular shapes and large quantities. When using molds for production, three processes are generally used to complete the production and manufacture of parts; the three processes are: the first sequence: blanking, the second sequence: forming, and the third sequence: trimming and punching. These three processes respectively use three sets of molds: blanking mold, forming mold and punching mold. Using such process steps and molds can complete the manufacturing process of parts from blanking to forming to finished products. At the same time, the utilization rate of materials can be increased through layout; but the three processes require three sets of different molds to complete, which greatly increases It not only increases the cost of molds and products, but also increases the installation of molds, increases the labor intensity of operators, and reduces production efficiency. the

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems in the existing technology, and propose a blanking and forming device, which can complete the two processes of blanking and forming of the workpiece at the same time, saving the cost of the mold and improving the production of the product efficiency. the

The purpose of this utility model can be achieved through the following technical solutions: a blanking forming device, which includes a lower template and an upper template arranged above the lower template, and a guide column 1 is arranged between the upper template and the lower template. A concave forming die is fixedly attached to the side of the template facing the lower template, and a convex forming punch is fixedly connected to the side of the lower template facing the upper template and facing the forming die. A ring-shaped blanking die is sheathed on the mold, and the upper plane of the blanking die is higher than the upper plane of the forming punch. the

Place the workpiece on the forming die, and as the upper template moves toward the lower template, the workpiece is first blanked under the action of the cutting force of the forming die and the blanking die to form a blanking sheet for forming. The blank falls onto the forming punch; then the upper template continues to move towards the lower template, and when the forming die moves to the bottom dead center of the mold, the blank sheet completes the forming of the workpiece under the cooperation of the forming die and the forming punch. The blanking and forming mold of this structure combines the blanking and forming processes into one process, which reduces the design and development cost of the mold.
