[0033] Referring to Figure 2 , a first screw 41 is arranged through the bottom of the two first sliding blocks 4, the first screw 41 is a bidirectional screw, and the two first sliding blocks 4 are threadedly connected to two threaded sections of the first screw 41 respectively, one end of the first screw 41 is rotatably connected to the side wall of the box 1, the other end of the first screw 41 is welded with a gear seat 411, the gear seat 411 is engaged with a bevel gear 421, a first transmission rod 42 is arranged through the bottom of the box 1, one end of the first transmission rod 42 is located outside the outer wall of the box 1 and connected with a first hand wheel 43, the other end of the first transmission rod 42 is connected to the bevel gear 421, a second sliding block 5 is slidably arranged on the two first sliding blocks 4, two inclined surfaces are formed on the bottom of the second sliding block 5, and the two inclined surfaces are respectively attached to the inclined surfaces of the two first sliding blocks 4, a second screw 51 is arranged through the second sliding block 5, the second screw 51 is threadedly connected with the second sliding block 5, both ends of the second screw 51 are rotatably connected to the side wall of the box 1, one end of the second screw 51 close to the first hand wheel 43 is welded with a second transmission rod 52, and the other end of the second transmission rod 52 away from the second screw 51 is located outside the box 1 and connected with a second hand wheel 53.

[0034] Referring to Figure 2The bottom of the support rod 2 is machined into a spherical end, and the top of the second slider 5 is machined into an inclined surface. Two inclined surfaces are symmetrically arranged on the top of the second slider 5 and are located on both sides of the length direction of the second slider 5. The two inclined surfaces on the second slider 5 have opposite inclination directions. The spherical ends of the four support rods 2 slide on the two inclined surfaces of the second slider 5 respectively. The top of the box 1 is provided with a sleeve 11. Four sleeves 11 are provided and are respectively fitted on the periphery of the four support rods 2. The end of the sleeve 11 near the mounting plate 3 is slidably connected to the top of the box 1. The end of the sleeve 11 away from the box 1 is machined into an inclined opening that fits the inclined surface of the second slider 5. The top of the box 1 is provided with a support bolt 6.

[0035] When using the progressive die leveling structure, set the corresponding number of leveling structures according to the number of sub-dies of the progressive die, and install the sub-dies on the mounting plate 3. Place the mounting plate 3 on the top of the housing 1 and insert the four support rods 2 into the four sleeves 11 respectively. At this time, the spherical end of the bottom of the support rod 2 abuts against the inclined surface of the second slider 5. By rotating the second handwheel 53, the second transmission rod 52 and the second lead screw 51 are rotated. At this time, the second slider 5, which is threaded to the second lead screw 51, slides on the two first sliders 4.

The support bolt 6 inserted into the positioning hole 32 can increase the stability of the support bolt 6 supporting the mounting plate 3 and increase the stability of the progressive die during stamping. The sleeve 11 can ensure that the spherical end of the support rod 2 slides smoothly along the inclined surface of the second slider 5. At the same time, it can increase the stability of the connection between the mounting plate 3 and the support rod 2 and the housing 1, and ensure the stability of the die on the mounting plate 3 when the progressive die is used. The inclined opening at the bottom of the sleeve 11 can ensure that the spherical end of the support rod 2 slides smoothly along the inclined surface of the second slider 5. By adjusting the sliding of the second slider 5, the position of the support rod 2 and the inclined surface of the second slider 5 can be adjusted to adjust the height of the contact point between the second slider 5 and the spherical end of the support rod 2. This can adjust the tilt angle of the mounting plate 3, reduce the operation steps when leveling the mounting plate 3, reduce the operation steps when leveling the progressive die, and facilitate the leveling of the progressive die.

[0037] When the leveler structure for the progressive die is used, rotating the first hand wheel 43 drives the first transmission rod 42 and the bevel gear 421 to rotate, at this time, the bevel gear 421 drives the gear seat 411 engaged with it to rotate, the gear seat 411 drives the first lead screw 41 to rotate, and the two first sliding blocks 4 move away from each other or move towards each other, so as to adjust the height of the second sliding block 5, and the height of the second sliding block 5 is adjusted through the sliding of the two first sliding blocks 4, and the distance between the mounting plate 3 and the box body 1 is adjusted, so as to adjust the height of the progressive die on the mounting plate 3, reduce the working steps when leveling the progressive die, and facilitate the leveling work of the progressive die.

[0038] Referring to Figure 2 and Figure 3 , the first transmission rod 42 and the second transmission rod 52 are respectively inserted into the first hand wheel 43 and the second hand wheel 53, and the end of the first transmission rod 42 and the second transmission rod 52 close to the first hand wheel 43 is machined to form a sliding key 7, the first hand wheel 43 and the second hand wheel 53 close to the box body 1 are machined to form a key groove 71 matched with the sliding key 7, the first hand wheel 43 and the second hand wheel 53 are both provided with a rotating cavity 72, the sliding key 7 can slide along the inner wall of the rotating cavity 72, and the rotating cavity 72 is communicated with the key groove 71, the first transmission rod 42 and the second transmission rod 52 are both sleeved with a pointer 8 away from the box body 1, the pointer 8 is attached to the outer wall of the box body 1, and the box body 1 is machined to form a scale disc 81 matched with the pointer 8, and the scale disc 81 is provided with two and located at the positions where the two box bodies 1 are attached to the pointer 8.

[0039] When the leveler structure for the progressive die is used, the first hand wheel 43 or the second hand wheel 53 is pulled away from the box body 1 and rotated, so that the sliding key 7 is matched with the key groove 71, at this time, rotating the first hand wheel 43 or the second hand wheel 53 can adjust the leveler structure to the progressive die, and when adjusting, the pointer 8 rotates with the first transmission rod 42 or the second transmission rod 52, indicating the rotation angle of the first lead screw 41 or the second lead screw 51, facilitating the leveling work of the progressive die, and after leveling, the first hand wheel 43 and the second hand wheel 53 are pushed to be attached to the outer wall of the box body 1, at this time, the sliding key 7 is no longer matched with the key groove 71, which can reduce the risk that the first hand wheel 43 or the second hand wheel 53 is accidentally touched after the progressive die is leveled and drives the first transmission rod 42 or the second transmission rod 52 to rotate, and ensure the safety and stability of the leveler structure during work.
