15 left side of inclined plane slide block of the delay structure A is equipped with unloading bolt 12, spring 1, stripper insert successively
14, stripper insert 14 is fixedly mounted on stripper 3, unloading bolt 12 sequentially pass through spring 1, stripper insert 14, tiltedly
Face sliding block 15, spring 2 16 are mounted on stripper sliding block 17.When upper mold moves upwards, spring 1 pushes unloading bolt 12
Initial position is returned to stripper sliding block 17.
Delay structure B (not shown) is arranged on the right of upper mold, and delay structure B includes the beveled punch mounted on fixed plate 2,
On stripper 3 stripper sliding block, bullet are disposed with the matched inclined plane slide block of beveled punch, inclined plane slide block left side
Spring two, inclined plane slide block are connect by spring two with stripper sliding block.
Stripper insert, spring one, unloading bolt, stripper are equipped on the right side of the inclined plane slide block of the delay structure B successively
Insert is fixedly mounted on stripper 3, and unloading bolt sequentially passes through spring one, stripper insert, inclined plane slide block, spring two and installs
On stripper sliding block, when upper mold moves upwards, spring one pushes unloading bolt and stripper sliding block to return to initial position.
Three-dimensional compressive stress structure includes the cavity plate sliding block 22 of corresponding top cutting punch 8, is mounted on nitrogen gas spring 2 20
On supporting plate 24, the mandril one installed between mandril 2 21, cavity plate sliding block 22 and supporting plate 24 that 24 the right and left of supporting plate is respectively arranged
23, concave template 4 is extended in the upper end of both sides mandril 2 21.Three-dimensional compressive stress structure is upward to product, to the left, have certain force to the right
Effect, ensure product punching face it is smooth, especially use nitrogen gas spring 2 20, nitrogen bigger than common spring elastic force in lower die
Gas spring 2 20 provides product power upward enough by mandril 1 and cavity plate sliding block 22, coordinates both sides mandril 2 21, right
Product formation three-dimensional compressive stress meets requirement of the part punching press to smoothness.
The operation principle of the utility model is specifically described below, with reference to the working condition one of figure 1, upper mold is under
Mould is in separated position, and when upper mold starts to move downward, upper mold presses against material strip 32 and also moves downward therewith；With reference to the work of figure 2
State two, when material strip 32 touches lower die, the meeting stop motion of stripper 3, upper die holder 1 and the continuation of fixed plate 2 move down, press
Contracting nitrogen gas spring 1, and the lower guild of upper die holder 1 and fixed plate 2 drives cutting punch 8 and beveled punch 11 to move downward, tiltedly

Because stripper sliding block 17 is blocked by mandril 25, so stripper sliding block 17 cannot slide at this time；With reference next to the work of Fig. 3
State three, 8 downlink punching material strip 32 of cutting punch are cut out product 40 from material strip 32, and press against cavity plate by product 40 and slide
Block 22, mandril 1, mandril 2 21, supporting plate 24 move downward, and nitrogen gas spring 2 20 is compressed, when upper mold moves to minimum point,
Mandril 2 21 is forced into minimum point at this time, and stripper sliding block 17 slides into the upper of mandril 2 21 because of the lateral force that spring 2 16 provides
Side.Upper mold moves upwards, and upper die holder 1, fixed plate 2, cutting punch 8, the beveled punch 11 of upper mold is driven to move upwards, and discharging
Plate 3 is because there is nitrogen gas spring 1 to push down and do not move temporarily, and since beveled punch 11 is upward, stripper sliding block 17 returns to initially
Position, after nitrogen gas spring 1 restores, the stripper bolt 9 in fixed plate 2 drives stripper 3 to move upwards, stripper sliding block 17
The mandril 2 21 that the position conceded makes also moves up, and product 40 is ejected lower die, and entire punching course terminates.
