Problems solved by technology

When stirring, the stirring rod is in contact with the metal material, and the heat in the metal material will be transferred to the stirring rod. Since the material of the stirring rod is usually mixed with other impurities such as carbon, the melting point of these impurities is usually low. After the temperature rises, these impurities will be melted and mixed into the metal material, so that there will be impurities in the final slurry, and the impurities will adversely affect the performance of the semi-solid die-casting workpiece

The vertical power part 32 in this embodiment adopts a hydraulic cylinder, and the push rod of the vertical power part 32 faces downward. The upper mounting base 4 is located below the mounting frame 3, and the push rod of the vertical power part 32 is connected to the top of the upper mounting base 4 through a flange, and the front and rear ends of the upper mounting base 4 are connected with a first flange through a flange. The guide rod 31 , the upper end of the first guide rod 31 penetrates the mounting frame 3 upwards, and cooperates with the mounting frame 3 in clearance...

Embodiment 2

[0050] On the basis of Example 1, such as image 3 As shown, the collecting tank 2 in the present embodiment is provided with a positioning cylinder, the positioning cylinder is vertically welded on the bottom of the collecting tank 2, the opening of the positioning cylinder is upward, and the inner diameter of the positioning cylinder is the same as the outer diameter of the stirring part 7, And the shape of the bottom of the positioning cylinder is the same as the shape of the bottom of the stirring part 7 . In this embodiment, when the stirring rod needs to be replaced, since the lower part of the stirring part 7 is in contact with the slurry, the surface of the stirring part 7 is slightly melted, and when the stirring rod slides downward, the lower end of the stirring part 7 can slide into the positioning cylinder Inside.

[0051] When replacing the stirring rod, manually start the vertical power part 32, so that the lower end of the stirring part 7 slides into the positi...

Embodiment 3

[0054] On the basis of Example 2, such as Figure 4 As shown, the rotating shaft 51 in this embodiment is not welded to the top of the connecting block 5 , and the lower mounting base 6 is no longer fixed to the housing 9 . The lower end of the rotating shaft 51 in this embodiment is rectangular, and the top of the connecting block 5 is provided with a rectangular guiding channel, and the lower end of the rotating shaft 51 is located in the guiding channel and fits with the guiding channel. In addition, the bottom of the upper mounting base 4 in this embodiment is fixed with an adjusting power part 41 by bolts. The adjusting power part 41 in this embodiment adopts a hydraulic cylinder, and the push rod of the adjusting power part 41 passes through the flange plate and the lower mounting base 6. fixed at the top.

[0055] The top of the connecting block 5 is provided with a connecting ring 42, the connecting ring 42 is sleeved on the rotating shaft 51 and has an interference f...

Description

technical field [0001] The invention relates to the field of die forging, in particular to a semi-solid pulper for die forging. Background technique [0002] Die forging is a forging method that uses a die to form a blank into a forging. The size of the forging processed by die forging is accurate, and the subsequent machining allowance is small. The traditional processing method is to melt the metal material into a liquid state first, then process the liquid metal material into a blank, and then use a mold to process the blank into a forging, and the molten metal material has a higher strength after solidification, so it needs to be stronger. The mold and high pressure can deform the blank, and the processing difficulty is also relatively large. [0003] Semi-solid die-casting is a die-casting method that can process metal materials into workpieces before the molten metal is completely solidified into a solid state. Unlike traditional die forging, semi-solid die-casting do...
