Description

Automobile bumper punching die

Technical Field

The application belongs to the technical field of mould plastics, especially, relate to an automobile bumper cut-out press.

Background

For plastic parts of automobile bumpers, there are two types, outer type and inner type. Aiming at large-area back-off at both sides of all automobile bumpers, external parting and internal parting can be adopted. The selection of the two types of parting modes mainly depends on the requirements of the automobile host factory of the final client on the bumper, generally, European and American automobiles mostly adopt an internal parting technology, and Japanese automobiles mostly adopt an external parting technology. The two parting modes have the advantages and disadvantages, the outer parting bumper needs to be treated to clamp wires, the processing procedures are increased, and the cost and the technical difficulty of the outer parting bumper are lower than those of the inner parting bumper. The internally-divided bumper perfectly molds the bumper once through a secondary orbital transfer control technology, so that the appearance quality of the bumper is ensured, the processing procedure and the processing cost of a plastic part are saved, but the internally-divided bumper has the defects of high mold cost and high mold technical requirement. When the external parting automobile bumper is produced and manufactured, a special die is needed when a position needing punching is arranged. And a punching die is added for products with holes, so that the hole requirement of the products is met.

Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, unless otherwise specified, "a plurality" means two or more.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art through specific situations.

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The utility model provides an automobile bumper cut-out press, belongs to stamping die, including mould main part 1, backup pad 4, clamp plate 2 and briquetting 3, mould main part 1 is the U type of transversely placing, and backup pad 4 is fixed in 1 bottom of mould main part, and clamp plate 2 is connected with 1 top of mould main part is portable, and briquetting 3 is fixed in 2 bottoms of clamp plate, treats that punching a hole bumper 5 arranges U type mould main part 1 middle part space in, and backup pad 4 supports treats that punching a hole bumper 5, clamp plate 2 pushes down and drives briquetting 3 and extrude the hole on treating punching a hole bumper 5.

In one embodiment, the supporting plate 4 is provided with a groove corresponding to the pressing block 3, and the pressing block 3 can go deep into the groove when being pressed down so as to ensure that the hole on the bumper 5 to be punched is completely pressed out.

According to different orifice shape requirements, in one embodiment, the compact 3 is a cylinder.

According to the requirements of different orifice shapes, the pressing block 3 is a cuboid in one embodiment.

In one embodiment, the platen 2 is connected to a power source for driving the platen 2 to move up and down, and the power source is a hydraulic pump.

In one embodiment, the pressing block 3 is detachably fixed at the bottom end of the pressing plate 2. The detachable pressing block 3 can meet the requirements of holes and holes as required, namely the bumper 5 to be punched can be processed with holes after the pressing block 3 is installed, and the bumper 5 to be punched can be processed with holes after the pressing block 3 is detached.
