Detailed Description

Referring to fig. 3 to 7, a necking and expanding mold includes a female mold 8, a cutter inserting mechanism located above the female mold 8, and an expanding punch mechanism located below the female mold 8. The bottom of the female die 8 is provided with a guide column 6, and the expanding punch mechanism is sleeved on the guide column 6 and slides up and down along the guide column 6. Two symmetrical slide blocks 9 are arranged in the female die 8. The female die 8 is internally provided with a sliding groove 83, and the sliding block 9 horizontally slides along the sliding groove 83.

The slotting tool mechanism comprises an upper mounting plate 1, a slotting tool mounting plate 2 fixed at the bottom of the upper mounting plate 1 and two symmetrical slotting tools 3 fixed on the slotting tool mounting plate 2, wherein a slotting tool inclined plane 31 is arranged on the inner side of each slotting tool 3, and the slotting tool inclined plane 31 is 60 degrees.

The expanding punch mechanism comprises a lower mounting plate 4, a punch mounting plate 5 fixed on the top of the lower mounting plate 4 and an expanding punch 7 fixed on the top of the punch mounting plate 5.

The die 8 is provided with an upper clamping plate 81 and a lower clamping plate 82, and the upper clamping plate 81 and the lower clamping plate 82 form a sliding groove 83 together.

The outside of slider 9 is equipped with direction inclined plane 91, and direction inclined plane 91 is 60, and the inboard of slider 9 is equipped with presss from both sides tight cambered surface 92, and the side of slider 9 is equipped with two symmetrical bosss 93, and the boss 93 blocks in spout 9. So that the slide 9 can slide horizontally in the die.

The working principle is as follows: an original workpiece 10 is firstly placed in a cavity of a female die, a flange of the original workpiece 10 is flatly attached to the top surface of the female die, when a slotting tool mechanism moves downwards, two slotting tools move downwards firstly, contact with a guide inclined plane 91 through a slotting tool inclined plane 31, drive two sliding blocks to slide inwards, clamp the workpiece through a clamping arc surface, drive the female die to wrap the whole product to move downwards, and a lower expansion punch enters a cavity hole of the workpiece to start expansion until the expansion punch is in place, so that the workpiece 20 is obtained.

The utility model completes the closing and expansion of the workpiece through the die, and has high precision and high efficiency.
