Embodiment Construction

[0014] Figure 1a Is for passenger car B-pillar 10, said pillar / product / component is formed by press hardening.

[0015] The product 10 is manufactured from a heated flat metal billet, then formed in a forming tool and cooled while held in an extrusion / forming tool to achieve the desired hardness. The manufacturing method described above is called press hardening and enables dimensionally precise sheet metal products to have high strength due to the fact that the sheet metal parts are pressed during the hardening process.

[0016] The product 10 shown has a central part in the form of a hat-shaped cross-section, comprising a central flange 15 , two sheet parts 16 , 17 and lateral flanges 18 , 19 . The product 10 has at its upper and lower ends parts 25, 26 connected to the chassis of the vehicle.

[0017] A press hardening tool (not shown) comprises upper and lower tools that are semi-form fit to form the configuration of the desired end product.

Abstract

The invention relates to a method of manufacturing a product (10) formed in a pressing tool, wherein the tool is also designed to carry out a cutting and / or punching operation on the product. The cutting operation / punching operation is incomplete, such that waste / scrap (33, 41; 52; 64) resulting from the cutting / punching operation remains with the product (10) when the product leaves the pressing tool. The waste / scrap (33, 41; 52; 64) is removed during a subsequent finishing. The waste / scrap (33, 41; 52; 64) remains with the product (10) via at least one connecting bridge (31, 42; 51; 61) or the like.

Description

technical field [0001] The invention relates to a method for producing shaped products in an extrusion tool according to the preamble of claim 1 . The invention also relates to the use of the method according to the invention. Background technique [0002] For example, in so-called press-hardened sheet metal products, subsequent cutting or subsequent stamping is sometimes necessary to meet specified profile requirements and / or achieve desired hole configurations, etc., sometimes with high tolerance requirements combined to consider. A significant problem in cutting / punching is how, for example, press-hardened tools remove cutting / punching waste from the tool in a reliable and efficient manner. [0003] Therefore, one of the problems encountered when performing such cutting / punching operations in extrusion tools is the need to remove the resulting cuts / punchings from the extrusion tool before a new initial blank is fed to the extrusion tool. scrap. This adversely affects ...
