Brief Patent Description - Full Patent Description - Patent Application Claims
TECHNICAL FIELD [0001] The present invention relates to a tool or a part thereof for carrying out operations such as pressing, cutting, hemming and the like and includes at least a first and a second tool part with different functions in the tool, for example a tool body amid an functional part disposed thereon in order, alone or together with some other additional functional part, or additional tool, to carry out the operation, the first-and the second parts possessing different material properties. [0002] The present invention also relates to a method for manufacturing a tool or a part thereof, for carrying out operations such as pressing, cutting, hemming and the like, and entails that the tool is given different material properties in different parts of the tool. BACKGROUND ART [0003] In the manufacture of a tool for the above-outlined purpose, it has previously been the practice to separately manufacture a tool body which subsequently, ill the example of a cutting tool, is provided with one or more cutters. The manufacture of the tool body may be put into effect by casting or by welding on the basis of suitably dimensioned sheet material of appropriately adapted material composition [0004] In the case of a cast tool body, this often requires heat treatment after the casting, whereafter machining is put into effect in order to obtain the requisite seats, guide pins and bolt holes for securing the cutters, but also in order to make possible securing of the tool body in a machine. [0005] Correspondingly, in the alternative of welding of the tool body, extensive machining is required in order to be able to secure one or more cutters on the tool body and in the correct position, and in order to be able to secure the tool in a machine. [0006] In the manufacture of the functional part or parts, in the above-disclosed example the cutters, which are intended for carrying out the. operations for which the tool has been designed, the point of departure has previously often been rod or bar material in which event the functional parts, in this example the cutters, are machined to the correct configuration, provided with apertures and anchorage bolts, guide pins and the like. This is often followed by a heat treatment, whereafter further machining such as, for example, grinding, is put into effect [0007] To manufacture a tool in the above-outlined maimer is extremely time-consuning and such manufacture is, as a result, often determinative of the time consumption required in the new manufacture of different products. [0008] It is also previously known in the art, in the manufacture of tools by welding, flash welding and similar methods, to apply a material of a different composition, for example to a tool body so that a functional part is formed thereon. By such means, a tool will be obtained which consists of a single material piece, but in which the material composition in different parts thereof differs. [0009] Also in this alternative, extensive machining is required, for example in the form of joint preparation in welding and after-treatment of a weld before additional welding material can be applied When the material application is completed, further machining is required, possibly also heat treatment and subsequent grinding before the tool is ready to be made operational. [0010] When a tool has become obsolescent, for example because the part which is produced in the tool has itself become obsolete, or because the tool has quite simply become worn out the entire tool is scrapped, even though the tool body could very well be re-used. This naturally entails a waste of material, time and money. Problem Structure [0011] The present invention has for its object to obviate the drawbacks inherent in the prior art technology. Principally, the present invention has for its object to shorten the production time for a tool, but also to minimise the need of machining in the manufacture of the tool and to male possible the retro-construction of an obsolescent tool. [0012] Concerning the tool, the present invention has for its object to design the tool or a part thereof such that different parts of the tool display different material compositions adapted so as to impart to the different parts their intended material properties. [0013] Concerning the method, the present invention has for its object to propose a method for the manufacture of a tool or a part thereof in which different parts of the tool may be given different material compositions and, consequently, different material properties. Solution [0014] The objects forming the basis of the present invention will be attained concerning the tool is this is characterised in that the first and the second tool parts are cast in one united piece and that they possess different material compositions. [0015] The objects forming the basis of the present invention will be attained concerning the method if this is characterised in that the tool is cast in one united piece, the casting material of at least two different material compositions being supplied to the different parts of the tool and at least the one casting material being supplied in liquid form.
