摘要： A heat sink for semiconductor components or similar devices, especially produced from an extruded aluminum alloy. The heat sink comprises cooling ribs which rise at a distance from a base plate and which are clamped in an insert groove made in the surface of the base plate, laterally limited by longitudinal or intermediate ribs with a coupling base that has an approximately rectangular cross-section. The coupling bases are held in their insert grooves in a form-fit and are cold-welded with the base plate at least in some sections. Cross ribs extend at a distance to one another on the surfaces of the intermediate ribs and have the form of upset heels that are linked with the coupling base in a form-fit.

摘要： An extrusion die (10) includes a die body (30) having an upstream face (32) and a downstream face (34) with an extrusion profile (22) passing through the body (30) from the upstream face (32) to the downstream face (34). The walls of the extrusion profile (22) being the bearing (46) of the die (10). A pocket (40) having tapered sidewalls (70) is formed in the upstream face (32) of the die (10) and surrounds the extrusion profile (22). The configuration of the pocket (40) improves the material flow through the die (10). The configuration of the pocket (40) depends on the configuration of the extrusion profile (22). The width of the pocket (40) is small at the fast areas of the extrusion profile (22) while being large at the slow areas of the extrusion profile (22). The pocket (40) alters the entry angle of material as it enters the die (10) thus reducing friction in the die (10) and allowing increased extrusion speeds. In conjunction with the pocket (40), the die (10) has a continuous bearing (46) having a length depending on the configuration of the extrusion profile (22).

摘要： An improved fixed dummy block assembly to be used with a heavy duty metal extrusion assembly including a hydraulic press and a billet container. The assembly includes a stem connected with the press in axial alignment with the billet container so as to be pushed by the press towards an open inlet end of the billet container. Further, the stem, which is generally elongate and includes a first end having an axial socket extending into the stem therethrough, is structured to receive an exterior dummy block member therein within the axial socket. The exterior dummy block member includes an expansion segment and a connector segment, the connector segment being structured to be axially and slidingly inserted into the axial socket of the stem so as to be securely, yet removably locked in place without the use of any threads. The expansion segment of the exterior dummy block member includes an open interior area having a bell head containment portion and a bell stem containment portion into which a compression bell is inserted and secured. The bell itself has a bell head which fits in the bell head containment portion and bell connector stem which extends into the bell stem containment portion and is secured therein in a threadless manner such that the bell head is retained in the bell head containment portion and will protrude slightly from a front end of the expansion segment in order to engage the metal billet first and engage the expansion segment in order to outwardly flex of the surrounding wall structure of the expansion segment.

摘要： A die (1) has a thin rod-shaped mandrel (2) tightly surrounded by the segments (11) of a gripper (3), the mandrel (2) being placed in the axial bore (5) of a mandrel holder (4). The inner peripheral surface of the axial bore (5) is shrinkage-fitted or otherwise fixedly fitted on outer peripheral surfaces of the gripping segments (11), thereby urging them to keep the thin rod-shaped mandrel (2) in place in the holder (4). The mandrel can have an extremely fine orifice forming end (9) of a diameter of 3 mm or less, such an fine can be prepared easily and precisely, and maintenance of the die can be done inexpensively when the orifice forming end will have been worn out or damaged.

摘要： An insert type extrusion die is presented for making small parts for use in electrical, automotive and other industries for manufacturing small component parts. The application of the invented die is illustrated for making multi-cavity flat aluminum tubes, which are used for small heat exchanger components, in automotive air-conditioners, condensors and radiators. The insert die is composed of a male die section having a protrusion part and a female die section having a die cavity is held detachably in a die holder. The male section is a roughly rectangular plate-shaped component, and has an integrally formed twist prevention region which is inserted into the receiver groove of the female section which is integrally formed thereon. The protrusion part defines the cavity shape of the multi-cavity flat tube, and the female section has the die cavity of the required cross sectional shape to define the outer shape of the tube. Because the male section is made as a small independent part, the male section is not only replaceable readily, but the extrusion pressure is low because the port area can be made large compared with the insert dies of the conventional type. The invented insert die is therefore durable and retains the original mechanical precision of a new die during its long service life. The cost of manufacturing the insert die is low because the male section is simple shaped and can be fabricated by such precision fabrication techniques as electric discharge machining.
摘要翻译：提出了一种插入式挤出模头，用于制造用于电气，汽车和其他工业中用于制造小型部件的小零件。示出了本发明的模具的应用，用于制造用于小型热交换器部件的多腔扁平铝管，在汽车空调，冷凝器和散热器中。插入模具由具有突出部分的阳模部分和具有模腔的阴模部分可拆卸地保持在模座中。凸形部分是大致矩形的板状部件，并且具有一体形成的扭转防止区域，其插入到整体形成在其上的阴部分的接收器槽中。突出部分限定多腔扁平管的腔体形状，并且阴部分具有所需横截面形状的模腔以限定管的外部形状。由于阳部形成为小的独立部分，所以阳部不仅可以容易地更换，而且挤出压力低，因为与常规类型的插入模具相比，可以使端口面积大。因此，本发明的插入模具是耐用的，并且在其长使用寿命期间保持新模具的原始机械精度。插入模具的制造成本低，因为阳部分是简单的形状，并且可以通过诸如放电加工的精密制造技术来制造。

摘要： The invention relates to a method and an apparatus for extruding sections from materials, such as aluminium or aluminium alloys, in which material which has been rendered plastic is forced through an extrusion gap formed in a die and in which the extrusion gap is bounded by separate, mutually oppositely situated running surfaces, in which method, as a consequence of the shape and/or length of the running surfaces and/or width of the extrusion gap, the material forced through the extrusion gap experiences a lower resistance at one side of the die than at the other side of the die, more material being forced through the extrusion gap at said one side than at said other side, a curved section being formed as a result of the difference in the amount of material at the one side and at the other side, the longitudinal axis of said section having a curvature with a certain radius. The longitudinally curved section emerging from the die is passed through a curved guide device after leaving the die, the curvature of the guide device essentially matching the curvature of the curved section. After emerging from the die, the section is cooled, after which it is clamped by gripping means and is pulled by the latter in such a way that the rate at which the section is extruded is kept essentially constant.

摘要： Apparatus for continuous extrusion of metals in which feed is introduced into a circumferential groove 26 (FIG. 3) in a rotating wheel 2 to contact arcuate tooling 22 and an abutment 24. The abutment 4 is spaced from the walls of the groove 26 so that in operation a lining of the feed material is produced. Indentations 52 assist in holding the lining in place. The extrusion is generally in a radial direction through an aperture 58. The extrusion orifices (not shown) may be of part annular cross-section of different area. The extrusion aperture may extend from outside the groove 26 to permit of increased orifice area.
