Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] see Figure 1-Figure 6 , is an extrusion device 100 provided by the present invention. The extrusion device 100 can be applied to extrusion processing of various cylindrical workpieces by means of rolling extrusion, especially suitable for extrusion processing of tungsten sponge. Squeeze, so as to seal the pores densely covered on the surface of the tungsten sponge body.

[0031] Such as figure 1 As shown, an extrusion device 100 provided by the present invention includes a horizontal mounting plate 101 and a vertical mounting plate 102 arranged perpendicularly to each other, through w...

Abstract

The invention provides an extrusion device. The extrusion device comprises a bearing assembly used for driving a product to rotate along the axis of the product, a lower pressing block abutting against the product from top to bottom, a first driving assembly used for driving the lower pressing block to move in the vertical direction, and a lower pressing assembly used for elastically connecting the lower pressing block with the first driving assembly; two first mounting shafts and a second mounting shaft located at the centers of the bottoms of the two first mounting shafts are arranged at the bottom of the lower pressing block; the second mounting shaft is sleeved with a first tungsten steel sleeve; and each first mounting shaft is sleeved with at least one bearing. According to the extrusion device provided by the invention, the first driving assembly drives the lower pressing block to move towards the product on the bearing assembly, and thus the product is extruded; and the bearing assembly is used for driving the product to rotate along the axis of the product, rolling extrusion of the product is achieved through cooperation of the bearing assembly and the lower pressing block, and force borne by the lower pressing block is transmitted to the bearings when the lower pressing block extrudes the product.

Description

technical field [0001] The invention relates to the technical field of automatic processing equipment, in particular to an extrusion device. Background technique [0002] Tungsten sponge is the main carrier of an impregnated barium tungsten cathode, which is made by powder metallurgy. The voids in the tungsten sponge are used to store the launch material and at the same time serve as a delivery channel for the launch material. After the tungsten sponge is made, diffuse and seamless-walled pores are formed on its outer surface. When making a barium tungsten cathode, it is necessary to squeeze the outer peripheral surface of the tungsten sponge to seal all the pores on the outer peripheral surface of the tungsten sponge. However, none of the extrusion equipment currently on the market is suitable for the extrusion processing of tungsten sponge, either cannot meet the hardness requirements of tungsten sponge, or cannot meet the extrusion requirements of the cylindrical struct...
