It is gradually expanded to entire arc slope, stress point can be shifted in pressurized process after being arranged in this way, avoid cushion block a certain
Position stress is concentrated, and is prolonged the case where impacting same position always, cause cushion block deformation failure in tens thousand of folding mold process
Cushion block service life is grown.
The further setting of the utility model：If circumferentially corresponding to decile in the first end face and second end face to be provided with
Dry the first block of spiral and the second block of spiral.
Using above-mentioned technical proposal, by circumferentially corresponded in first end face and second end face decile be provided with several
One block of spiral and the second block of spiral so that it is upper that there are multiple stress points between block and lower block, uniformly share stress, and edge
Circumference is arranged, and facilitates screwing up between block and lower block.
The further setting of the utility model：The first block of spiral arc slope upper edge axial screw is provided with guiding
Slot is provided with the guided way extended in guide groove on the second block of spiral arc slope for spiral in an axial direction.
Using above-mentioned technical proposal, pass through the guide groove and guided way of setting so that the first block of spiral and the second block of spiral
Between fitting sliding it is more steady, will not play.
The further setting of the utility model：The cross section of the guide groove and guided way is triangular in shape.
Triangle is utilized by the way that the cross section of guide groove and guided way is disposed as triangle using above-mentioned technical proposal
The acute angle of shape clears up the foreign matter in sliding groove in the sliding process of guide groove and guided way.
The further setting of the utility model：The end face of the upper block far from lower block is equipped with nut counterbore.
Facilitate the nut position of screw to sink in counterbore by the nut counterbore of setting using above-mentioned technical proposal, avoid
Nut position protrudes from cushion block and is collided with liftout plate.
