    摘要： Modular extrusion die tools for extruding an extrudable material into an extruded article. In at least some embodiments, an extrusion die tool comprises a base, a sizing plate, a mandrel, and a die holder. When the sizing plate and mandrel are removably inserted into the base, and the base is removably inserted into the die holder, a billet of extrudable material may be injected under high pressure into the die tool. As it exits the die tool, the material is extruded into a desired shape. Because of the extreme forces to which the extrusion die tools are repeatedly subjected, some portions of the die tools can wear out relatively rapidly. Other portions, however, wear at a much slower pace. Consequently, certain portions of the die tool may need to be replaced more frequently than other portions. Because the extrusion die tools of the present invention are modular, the highly-worn portions of a die tool may be replaced without replacing the entire tool.

    摘要翻译： 用于将可挤出材料挤出成挤压制品的模块化挤出模具。 在至少一些实施例中，挤出模具工具包括基座，定径板，心轴和模座。 当定型板和芯棒可拆卸地插入到基座中，并且基座可移除地插入模具座中时，可将高可挤压材料坯料高压注入模具工具中。 当它离开模具工具时，材料被挤出成所需的形状。 由于挤出模具工具被重复施加的极大力量，模具工具的一些部分可能相对较快地磨损。 然而，其他部分的穿着速度要慢得多。 因此，模具工具的某些部分可能需要比其他部分更频繁地更换。 由于本发明的挤压模具是模块化的，因此可以更换模具的高磨损部分而不替换整个工具。

    摘要： A hollow extruding die for extruding a hollow section of a zinc-containing aluminum alloy is provided. The die is protected from cracks and has an extended life, without requiring any substantial structural changes to the die. In the die mandrel of the die a mandrel is connected by bridges with an outer cylindrical member. The bridges have a tapered projection facing toward the mandrel. A 3 mm thick coating composed of a nickel alloy is bonded on the surface of the projection by padding the welding material. Instead of coating the bridges, a covering can be attached to the surface of the bridges. To receive the covering, an engaging groove extends from the root of the mandrel and along the surface of the bridges to the outer cylindrical member of the die mandrel. The covering is composed of the same steel material as that of the die or of the nickel alloy. The covering has a through hole for receiving the mandrel formed on the base. At the opposite sides of the through hole, the covering has projecting portions that are disposed parallel to the mandrel and the covering is tapered along the bridges.

    摘要： A method of forming an extrusion die comprises forming an extrusion aperture in a die piece, forcing a flowable material partly through the extrusion aperture so that the leading surface of the material becomes deformed in the extrusion direction, and then removing the exposed surface of the extrusion aperture, by chemical or electro-etching, so that the effective axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location. The axial bearing depth of the completed die at any location is thus inversely proportional to the resistance to flow at that location, resulting in substantially uniform flow over the whole of the die aperture.

    摘要翻译： 形成挤出模头的方法包括在模片中形成挤出孔，迫使可流动材料部分地穿过挤压孔，使得材料的前表面在挤出方向上变形，然后去除挤出的暴露表面 孔，通过化学或电蚀刻，使得在其周边的任何位置处的挤出孔的有效轴向深度对应于在该位置处的可流动材料的前表面的变形。 因此，任何位置处的完整的模具的轴向轴承深度与该位置处的流动阻力成反比，导致在整个模头孔口上的基本均匀的流动。

    摘要： The subject invention relates to a new method for manufacturing extrusion die tools that eliminates the step of hardening the steel after cutting the steel to form the desired extrusion die tool design. The new method involves the steps of cutting and finishing steel to form the desired extrusion die tool design, coating the die tool, or parts thereof, and hardening the coated die tool. The new method for manufacturing extrusion die tools reduces the time and the cost involved in their manufacture.

    摘要： The present invention provides a novel die assembly for extruding and drawing ferrous and non-ferrous metal, and also to a method of making the same. The die assembly according to the present invention comprises a die core (3); at least one pre-stressed ring (2) placed around the die core (3); and a die casing (1) surrounding the ring (2), wherein the ring (2) is plastically deformed and hardened by press fitting it to the casing (1) so that the ring has compression stress exceeding its material yield limit by 10-40%, and the mating geometric feature (5) of the core and the ring is tapered towards the exit, to thereby obtain a rigid container system in which a die core can be press fitted with a great force without die cracking. As a result, a long lasting die assembly with surprisingly high performance, small dimension and low production cost is obtained by assembling the die core by a great force without die cracking.

    摘要： An improved method of machining slots and material feed holes in a molding die such as an extrusion die designed to form a honeycomb structure of ceramics employed as a catalyst carrier of a catalytic converter for automotive vehicles. In one of the preferred embodiments, shallow holes are drilled in a die material and subjected to electrochemical machining to remove material from the bottoms of the shallow holes so that they communicate with the material feed holes without any burrs. In the other embodiment, the slots are cut using a rotary cutter in a given order which will balance reaction forces exerted on the cutter from both side walls of each slot to minimize deformation of the cutter during cutting of the slots, thereby preventing the slots from being curved undesirably.
