[0021] like Figure 1 As shown, an aluminum flattening die,
[0022] The positioning upper pressing block 1 is inserted into the middle axial groove of the upper punch fixing plate 2, and the bottom end of the positioning upper pressing block 1 contacts the upper side of the aluminum mold. The upper punch fixing plate 2 is suspended above the lower punch fixing plate 6 and the aluminum mold is placed horizontally between the two. The upper extrusion punches 3 are symmetrically installed on the left and right sides of the bottom end of the upper punch fixing plate 2. The upper punch fixing plate 2 is screwed and connected with the top ends of the two upper extrusion punches 3 by countersunk bolts. The bottom end of the upper extrusion punch 3 contacts the upper parts of the two ends of the aluminum mold, and the lower extrusion punch 4 It is inserted on the left and right sides of the lower punch fixing plate 6 and connected by screws. The top of the lower extrusion punch 4 is in contact with the lower parts of the two ends of the aluminum mold. A matching V-shaped positioning support block 5 is embedded in the middle axial groove of the lower punch fixing plate 6. The ball at the top of the V-shaped positioning support block 5 is in rolling contact with the lower side of the aluminum mold. The positioning upper pressure block 1, the upper punch fixing block 2 and the upper extrusion punch 3 form the upper mold part, and the lower extrusion punch 4, the V-shaped positioning support block 5 and the lower punch fixing plate 6 form the upper and lower mold parts.
[0023] Embodiment 1:
[0024] like Figure 1 and Figure 2 As shown, the aluminum mold product is loaded onto the V-shaped positioning support block 5, and the flanges on both sides of the aluminum mold product are close to the lower extrusion punch 4. The equipment is started. After the equipment is running, the upper mold part moves downward to form an extrusion process with the lower mold part. During the downward process, the upper extrusion punch 3 and the lower extrusion punch 4 contact the aluminum mold product and deform to produce a plane and thickness. When the product is extruded to the required thickness, it is flattened and formed. After flattening, the equipment automatically rises and positions the upper pressure block 1 for upper punching. After flattening, the equipment automatically rises and the V-shaped positioning support block 5 is used to push the material. The extrusion is completed, and finally the flattening and forming operation of the aluminum mold product is completed. The material is returned up and down, and the material return action is stable.
