Description

Floating Convex Mode Shear Bending Composite Fine Blanking Die

technical field

The utility model belongs to the field of punching die design, and relates to a shearing and bending composite fine punching die in a floating convex mode.

Background technique

Stamping die is a device used for pressure processing of materials. Its working principle is generally to drive the opening and closing surfaces of the upper die and the lower die through the die under the action of stamping to cut, punch, stretch, etc. the raw materials between them. Set the shape to form stamping parts. The fine blanking die is a new type of die in the field of existing product manufacturing. It is usually composed of a punch and a die that match up and down. The ring plate and the middle support plate are fixed, the die and the lower template are fixed, and the lower mold moves upward during work to complete the production. Composite fine blanking die refers to a fine blanking die structure in which the press completes multiple processes such as punching and blanking at one station in one stamping stroke.

Parts sometimes need to be bent during the processing process. At this stage, there are many processes for bending parts. The general bending die needs to complete at least three processes of pre-cutting, bending and blanking (or fine blanking first) Blanking and then general punching and bending), the efficiency is low and the cost is high.

Utility model content

The purpose of the utility model is to provide a floating convex mode shear bending compound fine punching die, which can have shear bending at one station during the stamping process, has fewer processing steps, high production efficiency and low cost.

The technical scheme that the utility model solves adopted is:

A shearing and bending composite fine-blanking die in a floating convex mode, comprising an upper mold and a lower mold, the upper mold includes an upper template, an upper backing plate, a middle support plate, a ring gear plate and a punch, and the upper backing plate is fixed on the upper template At the bottom, the punch is set at the bottom of the upper support plate, the middle support plate is connected with the upper formwork, the ring gear plate is fixed at the bottom of the middle support plate, the upper support plate passes through the middle support plate, the punch passes through the ring gear plate, and the lower die It includes a lower template, a lower backing plate and a concave die, the lower backing plate is fixed on the top of the lower template, and the concave mold is arranged on the top of the lower backing plate, and it is characterized in that: the punch includes a shearing and bending punch and a floating blanking punch, the shearing The cutting and bending punch is fixed on the upper backing plate. The shearing and bending punch and the floating blanking punch are guided by the ring gear plate. In the mold opening state, there is a certain gap between the floating blanking punch and the upper backing plate. .

The beneficial effects of the utility model are:

In the mold opening state, there is a certain gap between the floating blanking punch and the upper backing plate, the lower die moves upward during stamping, the die and the ring gear plate clamp the material, and within the floating range of the floating blanking punch, the lower die, The strip, the floating blanking punch, the ring gear plate, and the middle support plate move upward together, and the shearing and bending punch cuts and bends the material. When the floating blanking punch and the upper backing plate fit together, the shearing and bending The punch continues to shear the bending material while the floating blanking punch begins to shear the material to form the final part. The utility model can ensure that the bending and shearing of the bending parts can be completed in one stamping process, has fewer processing steps, simple mold structure, high production efficiency and low cost.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1, the layout diagram of the present invention is used for the bending parts 9. In this embodiment, it takes one process to complete the bending and shearing actions from the strip 11 to the final formed part 9.

As shown in Figure 2, a floating convex mode shear bending compound fine punching die includes an upper die and a lower die, and the upper die includes an upper template 1, an upper backing plate 2, a middle support plate 3, a ring gear plate 4 and The punch, the upper backing plate 2 is fixed at the bottom of the upper template 1, the punch is set at the bottom of the upper backing plate 2, the middle support plate 3 is connected with the upper template 1 through the equal height screw sleeve, and the ring gear plate 4 is fixed on the middle support plate 3 At the bottom, the upper backing plate 2 passes through the middle support plate 3, the punch passes through the ring gear plate 4, the lower mold includes the lower template 7, the lower backing plate 6 and the die 5, the lower backing plate 6 is fixed on the top of the lower template 7, The die 5 is located on the top of the lower backing plate 6 . The punch includes a shearing and bending punch 8 (for bending strips 11 and shearing materials, which can cut holes and shapes) and a floating blanking punch 10 (for cutting materials, which can cut holes and shape), the shearing and bending punch 8 is fixed on the upper backing plate 2, the floating blanking punch 10 is connected with the upper backing plate through a screw rod of equal height, the shearing and bending punch 8 and the floating blanking punch 10 Guided by the ring gear plate, there is a certain gap between the floating blanking punch 10 and the upper backing plate 2 in the mold opening state.

The punch of the utility model includes a fixed punch (shearing and bending punch 8) and a floating punch (floating blanking punch 10), and the bending is completed through the fixed punch (shearing and bending punch 8). The shearing is completed by the fixed punch (shearing and bending punch 8) and the floating punch (floating blanking punch 10). When stamping, the lower mold moves upward, the die 5 and the ring gear plate 4 clamp the strip 11, within the floating range of the floating blanking punch 10, the lower mold, the strip 11, the floating blanking punch 10 and the gear ring The plate 4 and the middle support plate 3 move upward together, and the shearing and bending punch 8 cuts the bending strip 11. When the floating blanking punch 10 and the upper backing plate 2 fit together, the shearing and bending punch 8 continues While shearing and bending the strip 11, the floating blanking punch 10 begins to shear the strip 11 to finally form the part 9. The device of the utility model can ensure that the two actions of bending and shearing of the bending parts 9 can be completed in one process of stamping, with less processing steps, simplified mold structure, high production efficiency and low cost.

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present utility model.
