Problems solved by technology

[0007] Although in this way a modification of the manufacturing process of hardened components with complex shapes can be achieved, it has also been shown that components produced in this way in the prior art, especially in their end regions (i.e. the introduction of fluid into the hollow area of ​​the workpiece location) does not have satisfactory quality
In particular this does not provide a fully hardened profile along its entire length
The degree of deformation of the workpiece in these areas is also unsatisfactory, which may lead to premature material failure
For this reason, it is often necessary to remove the ends of such components or profiles after forming or hardening, but this leads to excessive material waste or waste ratios and thus impairs the economics of the method

Embodiment Construction

[0058] figure 1 A part of a first exemplary embodiment of a device 1 for shaping a workpiece 2 to produce a shaped component is shown in section. The workpiece 2 consists of hardenable steel and in this case is a tubular workpiece formed from a tubular profile. The workpiece 2 additionally has a hollow region 2a. The device 1 comprises a tool 4 having two shaped mold halves 4a and 4b and an axially displaceable butt punch 6 . The shape of the profile to be produced is determined by the shaped inner peripheral surfaces of the mold halves 4a and 4b. The workpiece 2 has already been inserted into the tool 4 , wherein the opening of the hollow region 2 a of the workpiece 2 is closed sealingly by the counter punch 6 . For this purpose, the counter punch 6 rests with its surface 6 a designed as a sealing region in a sealing manner against the inner circumference of the workpiece 2 in the end region. For this purpose, the counter punch 6 is adapted to the workpiece 2 and is in this...

Abstract

The present invention relates to a method for producing a shaped component by means of a device, wherein a workpiece, which has a cavity and which consists at least partially of a steel material, is inserted into a tool of the device, and wherein a fluid is introduced under pressure into the cavity of the workpiece located in the tool by means of a docking stamp of the device, and the workpiece is hot-formed in the device. The problem of providing a method that allows for economic production of components, even of complex geometrical design, and simultaneously allows for satisfactory hardening of the components, is solved by counteracting the cooling of the workpiece in the region of the docking stamp. The invention further relates to a device, in particular for performing the method.

Description

technical field [0001] The invention relates to a method for producing shaped components by means of a plant, wherein a workpiece having a hollow region and consisting at least partially of steel is introduced into a tool of the plant, and wherein a fluid is introduced under pressure via a counter punch of the plant The hollow area of ​​the workpiece is located in the tool and the workpiece is thermoformed in the device. The invention furthermore relates to a device for forming a workpiece having a hollow area and consisting at least partially of steel, having a tool for receiving the workpiece and at least one butt punch for forming Fluid is introduced into the hollow area of ​​the workpiece located in the tool. Background technique [0002] It is known in the prior art that workpieces made of steel, such as pipes or slabs, or components made of workpieces, such as profiles, harden during or after their forming. Here, depending on the type of steel, the workpiece or compo...
