Problems solved by technology

[0008] It can be seen that the traditional integral extrusion shaft structure has two major disadvantages: 1. When extruding steel pipes with different inner diameters, it is necessary to use mandrels corresponding to different diameters
Therefore, in order to extrude steel pipes of different specifications, it is necessary to keep extrusion shafts of different specifications. At the same time, these extrusion shafts will be idle most of the time, resulting in a certain degree of waste.
In addition, the maintenance, maintenance and renewal of too many integral extrusion shafts also require a lot of cost, which makes the cost of the mold too high; The overall replacement cost is also higher

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] see figure 1 As shown, an extrusion machine with a combined extrusion shaft includes a frame 1 fixed on the foundation through a frame support 11 . The frame 1 also includes a lower arch beam 12, an upper arch beam 13 and uprights 14, and there are at least four uprights 14. The lower arch beam 12 and the upper arch beam 13 are respectively fixed to the lower end and upper end of the column 14 by steel wire winding or screw connection. The column 14 of the frame 1 is screwed on the frame support 11, and the frame support 11 is fixed on the foundation.

[0029] The frame 1 also includes a lower pad beam 15 and an upper pad beam 16 . The lower backing beam 15 is s...

Abstract

The invention provides an extruding machine with a combined extruding shaft. The extruding machine comprises a workbench mounted at the bottom a machine frame. An extruding shaft body of a hollow structure is fixedly arranged on the upper side of the workbench. A mandril which moves up and down in the vertical direction and is used for extruding blanks for forming is arranged in the hollow structure of the extruding shaft. An extruding pad with a hollow hole channel matched with the outer diameter of the mandril is fixedly connected to the upper end of the extruding shaft body. A movable die mechanism used for being matched with the mandril to extrude the blanks for forming is arranged on the extruding pad. The extruding machine with the combined extruding shaft can effectively improve the working efficiency and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of production of large-diameter seamless pipes, and more specifically, to an extrusion machine with a combined extrusion shaft. Background technique [0002] Extrusion machine is the most important equipment to realize metal extrusion processing by using metal plastic pressure forming. Its main feature is to process and shape the metal blank at one time, with fast processing speed and reliable quality. [0003] Large-diameter pipe extrusion machines are divided into two types: long-distance extrusion machines and short-distance extrusion machines. The short-stroke extruder means that the stroke of the master cylinder is shorter than that of the conventional master cylinder, which can reduce the idle stroke time and improve the efficiency. The relative position of the extrusion shaft and the mandrel of the long-distance extruder is fixed, so the extrusion shaft and the mandrel need to move a longer stroke t...
