after the aluminum raw material is extruded, the pushing mechanism 6 can drive the pushing plate 7 to push the extruded aluminum raw material to the right side, the left end of the pushing cylinder 62 automatically turns under the connection effect of the hinge when the pushing cylinder 62 performs the extension motion, the pushing cylinder 62 enables the pushing plate 7 arranged at the right end of the pushing cylinder 62 to be always attached to the lower side wall of the blanking frame 3 under the downward pressure effect of the downward pressing spring 63, the positioning wheel 56 can roll the aluminum raw material when the aluminum raw material is pushed to the right side, the tilting height of the extruded aluminum raw material is limited, and the arc-shaped protrusion on the positioning wheel 56 can increase the rolling effect of the aluminum raw material;

when the aluminum raw material moves to the position of the guide frame 35, the guide frame 35 can guide the moving angle of the extruded aluminum raw material, the righting roller 36 can limit the longer aluminum raw material to prevent the upper end of the aluminum raw material from turning when the aluminum raw material slides downwards, and the decelerating roller 37 can decelerate the aluminum raw material to a certain degree, so that the aluminum raw material is prevented from splashing when moving into the smelting furnace 2; when the aluminium raw materials landing is in smelting furnace 2, control propelling movement cylinder 62 and contract for when the right-hand member of deflector 71 contacts with propelling movement plate 7, propelling movement plate 7 can carry out the upward movement along the structure of deflector 71, prevents that propelling movement plate 7 from hindering the conveying of aluminium raw materials, card on deflector 71 when oblique baffle 72 can prevent the conveying of aluminium raw materials.

The invention can respectively lock the inner side surface and the outer side surface of the ball valve seat, so that the position of the ball valve seat is positioned, the rotating stability of the ball valve seat is increased, and the cutting precision of the ball valve seat is increased.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
