Description of the solution

Scheme one: described with reference to fig. 5 is: based on the first-stage assembly 5 in the upper layer position, the upper connecting slide block 501 can move up and down through the guide post 1, and the upper connecting slide block 501 and the guide post are in rotary connection, and the lower connecting slide block 501 in the first-stage assembly 5 in the lower layer position and the transmission shaft of the hydraulic cylinder 7 are in rotary connection, so that the aim is to: when the two first-stage assemblies 5 bear forces in two directions, the lower connecting slide blocks 505 only maintain the movement process in the vertical direction and do not deflect angularly, but when the upper connecting slide blocks 501 and the lower connecting slide blocks 505 are close to each other, the inclined spring plates 503 are pressed and deform, so that in order to meet the deformation process, any one of the upper connecting slide blocks 501 and the lower connecting slide blocks 505 needs to be ensured to rotate, and in this embodiment, the upper connecting slide blocks 501 need to deflect at a small angle, so that during the movement process of the first-stage assemblies 5, except the buffer effect of the connecting springs 4, the deformation process of the inclined spring plates 503 is utilized to play a role in the buffer protection process of the second stage;

scheme II: for the technical content of the first scheme, when the upper connecting slide block 501 deflects with small angle deflection mechanical energy, the upper orientation block 601 and the lower orientation block 604 are respectively driven to deflect, for limiting the deflection directions of the upper orientation block 601 and the lower orientation block 604 by limiting the bending angle of the inclined reed 503, for referring to fig. 6, the inclined directions and the bending radians of the inclined reeds 503 in the two first-stage assemblies 5 are equal, the first-stage assembly 5 at the upper layer position drives the upper orientation block 601 to rotate anticlockwise, and the first-stage assembly 5 at the opposite lower side position drives the lower orientation block 604 to rotate clockwise, so that the movement process between the upper orientation block 601 and the lower orientation block 604 is finally formed, specifically: the butting ejector rod 606 moves in a directional manner in the differential semi-annular groove 605, and because of the height limitation of the position in the differential semi-annular groove 605, the upper directional block 601 and the lower directional block 604 can move slowly and approach to the movement mode and are combined to the position of the directional reed 602, the directional reed 602 is extruded, so that the directional reed 602 contacts the inner wall of the cavity in the guide sleeve 2, and a part of the force is converted into a force in a rotating direction firstly based on a vertical direction, and then the force in the rotating direction is converted into a force in a vertical direction, finally the force in the vertical direction is converted into a force in a horizontal direction, the force born by the whole structure is gradually reduced through a plurality of conversion processes, and finally the force is born by the guide sleeve 2, so that the guide pillar 1/the guide sleeve 2 is prevented from generating larger mechanical friction damage;

Example III

The following describes the procedure of the first and second embodiments:

in the use process of the bidirectional hedging guide sleeve assembly, the guide post 1 and the guide sleeve 2 are respectively arranged at the upper template position and the lower template position in the die, and the following stages are set according to the operation process of the die:

stage one: setting a bidirectional hedging guide sleeve assembly of a die in a die splitting state as an initial stage, wherein in the initial stage, a first-order assembly 5 and a second-order assembly 6 are in initial positions, specifically: the lower connecting sliding block 505 in the first-stage assembly 5 positioned at the upper side is positioned on the same horizontal plane with the inner wall of the upper end of the cavity, and the lower connecting sliding block 505 in the first-stage assembly 5 positioned at the lower side is positioned on the same horizontal plane with the inner wall of the bottom end of the air; the second order component 6 is in a stretched state; and the compensation gap between the first-order component 5 positioned at the lower side and the inner wall of the bottom end of the cavity is at the minimum value;

stage two: when the guide post 1 moves downwards and approaches the guide sleeve 2 in a die closing state, the hydraulic cylinder 7 synchronously provides upward thrust for the first-stage assembly 5 positioned at the lower side, so that a compensation gap is formed between the lower connecting sliding block 505 in the first-stage assembly 5 positioned at the lower side and the inner wall of the air bottom end;

stage three: in the second stage, the inclined reed 503 in the upper connecting slide block 501 and the lower connecting slide block 505 are extruded and drive the upper connecting slide block 501 to rotate at a small angle along the bending direction of the inclined reed 503, wherein the lower orientation block 604 is subjected to vertical upward pressure through the first-stage component 5 positioned on the lower side, the upper orientation block 601 is subjected to vertical downward pressure through the first-stage component 5 positioned on the upper side, and the upper orientation block 601 and the lower orientation block 604 correspondingly rotate through the small angle rotation of the upper connecting slide block 501, so that the orientation reed 602 is subjected to pressure in the upper direction and the lower direction, bends and contacts the inner wall position of the cavity;

stage four: when the two first-order components 5 are pressed and the second-order components 6 are extruded at the same time, the hydraulic cylinder 7 drives the first-order components 5 positioned at the lower side to reset, so that the compensating clearance is restored to the minimum state.

The scheme is as follows: the present embodiment is described in conjunction with the first and second embodiments, in which the vertical downward force applied by the first-stage component 5 is generated by the movement of the mold during the actual operation, and for the second stage, it is necessary to provide the upward pressure by the hydraulic cylinder 7 in the stage synchronization state, which is described in detail below:

in the first stage, or it is understood that in the normal state, the lower first-stage assembly 5 is always located at the bottom position of the cavity, only when the die starts to be closed, an upward acting force needs to be generated by the hydraulic cylinder 7, so that a compensating gap with a certain space is formed between the first-stage assembly 5 and the bottom position of the cavity, and the height of the compensating gap is equal to the movement stroke of the hydraulic cylinder 7, and the movement stroke can be determined according to the production requirement of the accessories, in particular, the deformation height difference during stamping of the accessories;

in the specific operation process, the movement form of the hydraulic cylinder 7 is determined according to the movement stroke of the die, particularly, when the upper die plate and the lower die plate reach the pre-stamping stroke position, the hydraulic cylinder 7 is quickly started to drive the first-order assembly 5 positioned at the lower side to move upwards, and the movement stroke is smaller than the deformation height difference;

when the die continues to move from the stroke position of the pre-stamping, the hydraulic cylinder 7 is slowly reset, which can be understood as follows: the first-order component 5 positioned at the lower side loses upward pressure until the first-order component 5 positioned at the lower side is completely attached to the bottom end position of the cavity, then the contents of the third stage and the fourth stage are combined, and the impulse generated when the die is assembled is dispersed step by step through the second-order movement formed by the movement form of the first-order component 5 to the second-order component 6, the movement form between the two first-order components 5 and the movement form of the second-order component 6, and finally the impulse is borne by the guide sleeve 2, so that larger mechanical friction damage between the guide posts and the guide sleeves is avoided.

To sum up: based on the use principle of the guide sleeve/guide pillar in the die, the current structure is optimized and improved, and the specific scheme is as follows: the two-way opposite impact structure is additionally arranged by the first-order component and the second-order component, the motion process of the two-way opposite impact structure comprises two groups of acting forces which are opposite to each other, the force along the vertical direction is switched into the force in the rotating direction, and then the force in the whole direction is switched into the horizontal force acting on the guide sleeve, and the purpose is that: the stamping device is suitable for small-stroke stamping requirements, reduces the motion bearing force of the guide post/guide sleeve, maintains the center stability in the integral structure, is used for stabilizing the motion precision of the die, and avoids mechanical friction damage of the guide post/guide sleeve under the condition of long-term motion.
