摘要： A method is used to manufacture a tube having a hollow interior for housing an axle shaft. The tube is formed in a single machine having a fixed base and a single press structure movable toward the fixed base. The single machine includes first and second die assemblies coupled to the fixed base and first and second mandrels coupled to the single press structure. The method includes the steps of placing a billet into the first die assembly, pressing the billet into the first die assembly with the first mandrel to producing a pre-formed billet, and moving the pre-formed billet from the first die assembly to the second die assembly. THE method further includes the steps of pressing the pre-formed billet into the second die assembly with the second mandrel to elongate the pre-formed billet and form a hollow interior therein to produce an extruded tube.

摘要： Disclosed is an impact extrusion can making system that uses induction heating to preheat an extruder punch and an extruder forming die, to increase yield during a cold start. In addition, a highly precise laser measuring device is used to measure dome thickness, so that stroke length and/or position of an extruder and/or extrusion die can be automatically adjusted in a predictive control system. High quality products with high yield are produced using these techniques.

摘要： Systems, devices, and methods are described for extruding a material. In certain embodiments, an extrusion press system includes an extrusion die supported by a first support structure and a centering insert supported by a second support structure, wherein the centering insert guides a material to be extruded into the extrusion die. A positive stop may be coupled to the first support structure and extend towards the second support structure, wherein the positive stop defines a travel distance between the first support structure and the second support structure. In certain embodiments, movement of the second support structure towards the first support structure is limited by the positive stop to the travel distance. In certain embodiments, the positive stop is configured to adjust the travel distance.

摘要： This disclosure relates to a hold down mechanism which is particularly adapted to apply a preselected hold down pressure on an element. It employs a bar which is pivotally mounted on a support member with the bar having a hold down surface thereon so positioned that when the bar is pivoted in a selected direction the hold down surface will engage the element in clamping relation and further pivoting of the bar in the same direction will result in the shifting of the pivot point for the bar from the pivot member to the hold down surface. The pivot member is spring loaded for lifting movement at this time with an associated spring pack providing for a controlled loading by the hold down surface against the element. A movable cam member having a wedge shaped lower end moves between a cam follower carried by the arm and a fixed cam follower to effect the controlled pivoting of the bar.

摘要： The disclosure of this invention pertains to an extrusion, forging or shaping press. The drawings illustrate an extrusion press incorporating three billet containers, the use of which enables three different operating phases to be carried out simultaneously. The disclosure particularly relates to the employment of an hydraulic piston cylinder assembly and rack and gear for providing a finite or definite degree of precise rotation of the containers in their advancement from one phase or station to another phase or station.

摘要： The invention relates to extrusion and pipe presses (1), comprising a press frame consisting of a cylindrical spar (2) and a counter spar (4) connected thereto, in which a mobile billet container holder (7) supporting a billet container (8), which puts a billet (18) to be pressed, which was introduced by a loading device, into a press position in front of the counter spar (4) with the associated tool (38), and a mobile punch crosshead (6) are provided. In the cylindrical spar (2), a main cylinder, or press cylinder, is arranged, which in the cylinder housing (9) thereof receives a press piston (11), which at the front end thereof that is supported by the punch crosshead (6) is connected to a press punch (19). A compensation tank (15), which delivers hydraulic oil to the press piston (11) by way of a slider plate (28), is assigned to a main cylinder housing (9) connected to a tank line. With an extrusion press such as this, the considerable hydraulic expenditure, and in particular the non-productive time, are to be substantially reduced, while making the structural design more compact and simple at the same time. To accomplish this, the advancing and feed motions of the billet container holder (7) and punch crosshead (6) with press piston (11) are carried out by electromotive force, and both the precompression of the billet (18) loaded into the billet container (8) and the subsequent compression of the billet (18) are done by hydraulic loading of the press piston (11). Electric motors (12, 13) are assigned to the punch crosshead (6) and the billet container holder (7) as adjustment drives. A large-scale filling valve (20) is integrated in the cylinder housing (9) of the main cylinder for loading the press piston (11).

摘要： The stem slide device of the present invention in an extruder has a stem vertical movement support (71) and slide guide members (72-1, 2) fastened to the support and forming guide grooves. A stem (6) pushing against a billet loaded in a container is held at the slide table (73) horizontally. The slide table slides in the vertical direction along the vertical face of the support. When the slide table is positioned at the bottom end of the guide groove, the hydraulic cylinders (77-1, 2) are driven so that the rods (78-1, 2) push the back surface of the slide table against the vertical face of the support. Therefore, the axis of the stem is held matched with the axis of the container.
