Description

Technical Field

[0001] The invention relates to the technical field of metal powder processing and forming, and in particular to a metal powder stamping and forming processing device. Background Art

When the metallurgical powder is pressed and compressed into shape, a part of the metallurgical powder is squeezed to fly out in all directions and fall into the inside of the material receiving mechanism. The metallurgical powder slides inside the material receiving mechanism and enters the inside of the collecting mechanism to collect the metallurgical powder. The driving mechanism is installed inside the support table, and the driving mechanism is installed inside the collecting mechanism. The collecting mechanism and the stamping mechanism are respectively installed at the bottom and the top of the moving mechanism. When the stamping mechanism extrude the metallurgical powder, the stamping mechanism drives the gas of the compression mechanism to move.

Then, when the stamping die moves upward to reset, the magnetic plate is in magnetic contact with the sliding ring to limit the limiting rod, so that the limiting rod limits the stamped part and separates it from the stamping die. The ejecting assembly is installed between the lower die and the movable seat, and is used to drive the stamped part to move upward to the outside of the lower die. The unloading assembly is installed between the loading frame and the movable seat, and is used to discharge the metal powder into the lower die.

Then, when the stamping die moves upward and resets, the magnetic plate and the sliding ring cooperate to limit the limit rod, and the limit rod limits the parts. The limited parts are smoothly separated from the stamping die moving upward to prevent the stamped parts from adhering to the stamping die and affecting subsequent stamping, thereby improving the efficiency of metal powder stamping.

[0017] 2. Under the action of the striking plate, whenever metal powder falls into the lower die, the reciprocating swing of the striking plate can strike and vibrate the lower die, so that the metal powder is evenly dispersed in the lower die, which can prevent the metal powder from concentrating in one position and causing quality problems in the stamped parts, thereby ensuring the quality of the stamped parts.

[0018] 3. Under the action of the brush, whenever the loading frame moves to the right, the L-shaped rod can drive the brush to move to the right. The brush moves to the right to remove the metal powder attached to the bottom of the stamping die, which can prevent a large amount of metal powder from adhering to the bottom of the stamping die and affecting subsequent stamping, thereby ensuring the subsequent stamping quality.

[0033] First, pour a proper amount of metal powder into the charging frame 5, and the metal powder is discharged into the discharge pipe 14 and contacts the screw conveying shaft 141, then start the telescopic rod of the cylinder Ⅰ4 to drive the movable seat 3 to move right, the movable seat 3 moves right to drive the discharge pipe 14 and the charging frame 5 to move right, the movable seat 3 moves right to drive the trigger rod 134 to move right, the trigger rod 134 moves right to drive the swing plate 135 to move upward, the swing plate 135 drives the contact plate 133 to move upward, the contact plate 133 drives the movable frame 132 to move upward, the movable frame 132 drives the push rod 13 to move upward, and when the trigger rod 134 continues to move right and contacts the contact plate 133, the swing plate 135 and the contact plate 133 stop moving upward, and the trigger rod 134 slides on the contact plate 133. When the trigger rod 134 moves to the right and loses contact with the contact plate 133, due to the effect of gravity, the movable frame 132 drives the push rod 13 and the contact plate 133 to move downward and reset, and the contact plate 133 drives the swing plate 135 to move downward and reset, and then the discharge pipe 14 moves to the right so that the discharge end corresponds to the lower mold 2, the cylinder Ⅰ4 is closed, and the servo motor 142 is started to drive the screw conveying shaft 141 to reverse, and the screw conveying shaft 141 reverses and drives the metal powder to move to the right and be discharged from the discharge pipe 14, and the discharged metal powder falls into the lower mold 2 and contacts the push rod 13. When the lower mold 2 is filled with an appropriate amount of metal powder, the servo motor 142 is closed, and the cylinder Ⅰ4 is started to drive the movable seat 3 to move to the left and reset, and the movable seat 3 drives the trigger rod 134 to move to the left and contacts When the top of the plate 133 slides upward and the trigger rod 134 contacts the right side of the swing plate 135, the trigger rod 134 drives the swing plate 135 to swing downward, the torsion spring 136 is compressed, and the trigger rod 134 resets and disengages from the swing plate 135. Due to the action of the torsion spring 136, the swing plate 135 swings upward and resets, and then the stamping position of the stamping die 7 is started to heat, and then the cylinder II 8 is started to drive the stamping die 7 to move downward, and the stamping die 7 drives the limit rod 9 and the magnetic plate 10 to move downward, and the stamping die 7 moves downward and contacts the metal powder, and the stamping die 7 cooperates with the lower die 2 to stamp and form the metal powder, and the metal powder is stamped into the required parts. At this time, the limit rod 9 contacts the parts, and the magnetic plate 10 is in magnetic contact with the sliding ring 12, and the cylinder II 8 can be started to drive the stamping The die 7 moves upward to reset. Due to the magnetic adsorption of the magnetic plate 10 and the sliding ring 12, the magnetic plate 10 and the sliding ring 12 cooperate to limit the limit rod 9, and the limit rod 9 limits the stamped parts, so that the parts can be smoothly separated from the stamping die 7 moving upward to prevent the stamped parts from adhering to the stamping die 7 and affecting subsequent stamping, thereby improving the efficiency of metal powder stamping. The stamping die 7 moves upward to compress the compression spring 11. When the compression spring 11 is compressed to the maximum stroke, the stamping die 7 drives the limit rod 9 to move upward through the compression spring 11 to break contact with the parts, and the limit rod 9 drives the magnetic plate 10 to move upward to break contact with the sliding ring 12. Due to the action of the compression spring 11, the limit rod 9 shrinks to the inside of the stamping die 7 and resets.Start the cylinder Ⅰ4 again to drive the movable seat 3 to move rightward, so that the push rod 13 moves upward to drive the stamped parts to move upward to the outside of the lower die 2, and then the movable seat 3 moves rightward to move the stamped parts to the right and drop them from the workbench 1 for collection.
