Description
Technical field
The utility model relates to a kind of die self-opening device that is used for pressing equipment, belongs to the pressing equipment field.
Background technology
Be illustrated in figure 1 as the pressing equipment of mould up and down is installed in the prior art, as seen patrix 3 is the bottoms that are fixed on the slider of punch 1 of top, counterdie 6 is the tops that are fixed on the punch press platform 2 of below, guide pin bushing 4 is the bottoms that are fixed on patrix 3, and the guide pillar 5 that is complementary with guide pin bushing 4 is the tops that are fixed on counterdie 6.When carrying out the punch ram of big stroke, slider of punch 1 moves to top dead-centre, and patrix 3 will break away from counterdie 6, and guide pin bushing 4 also breaks away from guide pillar 5.From top dead-centre punch press platform 2 motion processes downwards, guide pin bushing 4 does not have guide pillar 5 channeling conducts at slider of punch 1, and this just will lean on the precision of lathe self to guarantee fully.If if mould does not have clamping to put in place up and down, the cutter phenomenon will occur gnawing in clamping, promptly Xia Fang guide pillar 5 is bended by the patrix 3 of top, can have a strong impact on the precision of equipment like this, even can make the mould damage of whole pressing equipment.
Summary of the invention
The utility model provides a kind of die self-opening device that is used for pressing equipment, is subjected to the influence of stroke to solve the mould of pressing equipment in the market, and guide pillar is bended by patrix and the defective that has a strong impact on even damage mould easily in the process of big stroke.
The structure of the die self-opening device in the pressing equipment of the present utility model is as follows: it comprises the counterdie at the top of the punch press platform that is fixed on the below, be fixed on the guide pin bushing and the guide pillar that is fixed on the top of counterdie of the bottom of patrix, there is bolt to be vertically fixed on the top of counterdie, bolt guide pin bushing and bolt mate and are vertically fixed on the bottom of patrix, spring entangles bolt and bolt guide pin bushing and its top and is fixed on patrix, the bottom is fixed on the counterdie, patrix is fixed on the top of counterdie by spring, during the nature of spring when not being subjected to the slider of punch impulsive force, the horizontal plane at place, guide pin bushing bottom is higher than the horizontal plane at place, guide pillar top.Can make upper and lower mould in the bootup process of guide pillars and bushes, move by such structural design always, and guide pillar can not break away from guide pin bushing, effectively avoided may the bend defective of guide pillar of under big stroke slider of punch, the service precision and the service life of having improved equipment.
In order to prevent that further guide pillar breaks away from guide pin bushing, further, the internal diameter of the bolt guide pin bushing of bolt guide pin bushing bottom bottom guide hole is less than the external diameter of the bolt head at bolt top.Like this, bolt can slide in the bolt guide pin bushing and can not break away from, and guarantees that simultaneously guide pillar does not break away from guide pin bushing.
The beneficial effect of the die self-opening device in the pressing equipment of the present utility model is: by the die self-opening device in this pressing equipment, can be so that upper and lower mould moves in the bootup process of guide pillars and bushes always, and guide pillar can not break away from guide pin bushing, effectively avoided may the bend defective of guide pillar of under big stroke slider of punch, the service precision and the service life of having improved equipment.

The 1-slider of punch, 2-punch press platform, 3-patrix, 4-guide pin bushing, 5-guide pillar, 6-counterdie, 7-bolt guide pin bushing, 71-bolt guide pin bushing bottom guide hole, 8-bolt, 81-bolt head, 9-spring.
The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
Be illustrated in figure 1 as the structural representation of pressing equipment in the prior art.As seen patrix 3 is the bottoms that are fixed on the slider of punch 1 of top, and counterdie 6 is the tops that are fixed on the punch press platform 2 of below, and guide pin bushing 4 is the bottoms that are fixed on patrix 3, and the guide pillar 5 that is complementary with guide pin bushing 4 is the tops that are fixed on counterdie 6.When carrying out the punch ram of big stroke, slider of punch 1 moves to top dead-centre, and patrix 3 will break away from counterdie 6, and guide pin bushing 4 also breaks away from guide pillar 5.From top dead-centre punch press platform 2 motion processes downwards, guide pin bushing 4 does not have guide pillar 5 channeling conducts at slider of punch 1, and this just will lean on the precision of lathe self to guarantee fully.If if mould does not have clamping to put in place up and down, the cutter phenomenon will occur gnawing in clamping, promptly Xia Fang guide pillar 5 is bended by the patrix 3 of top, can have a strong impact on the precision of equipment like this, even can make the mould damage of whole pressing equipment.
Structural representation after being illustrated in figure 2 as die self-opening device in the utility model pressing equipment and resetting.As seen, counterdie 6 is fixed on the top of the punch press platform 2 of below, guide pin bushing 4 is fixed on the bottom of patrix 3, guide pillar 5 is fixed on the top of counterdie 6, there is bolt 8 to be vertically fixed on the top of counterdie 6, the bottom that bolt guide pin bushing 7 and bolt 8 mate and be vertically fixed on patrix 3, spring 9 entangles bolt 8 and bolt guide pin bushing 7 and its top and is fixed on patrix 3, the bottom is fixed on the counterdie 6, patrix 3 is fixed on the top of counterdie 6 by spring 9 and breaks away from the slider of punch 1 of top, during the nature of spring 9 when not being subjected to slider of punch 1 impulsive force, the horizontal plane at place, guide pin bushing 4 bottom is higher than the horizontal plane at place, guide pillar 5 top.
Be illustrated in figure 4 as the die self-opening device partial structurtes schematic diagram in the utility model pressing equipment, as seen, (internal diameter of the bolt guide pin bushing bottom guide hole 71 of 7 bottoms is less than the external diameter of the bolt head 81 at bolt 8 tops for the bolt guide pin bushing.
Structural representation before being illustrated in figure 3 as die self-opening device in the utility model pressing equipment and resetting.As seen, spring 9 compresses when being subjected to the impulsive force of slider of punch 1, and simultaneously, guide pillar 5 slides in guide pin bushing 4, and bolt 8 slides in bolt guide pin bushing 7.When slider of punch 1 moves upward and breaks away from patrix 3, patrix 3 resets under the elastic force effect of spring 9, and owing to bolt head 81 is stopped by bolt guide pin bushing bottom guide hole 71, therefore, spring 9 can further not move up, guarantee that further guide pillar 5 remains in the guide pin bushing 4, and shuttling movement again and again.
Below only be specific embodiment of the utility model, any those skilled in the art can think variation all drop within protection scope of the present invention.
