Preferably, a magnet is fixedly connected to one side of the blocking rod close to the die core.
Preferably, the screw groove is formed in the blanking die, and the power screw is meshed in the blanking die, so that the power screw cannot be meshed with the rotating shaft immediately after rotating.
Preferably, the triangle is scraped the inside extrusion spring that is provided with of pole, scrapes the pole at the triangle and breaks away from the centrifuging tube time, because the triangle scrapes the inside extrusion spring that sets up of pole, and the pole takes place to deflect is scraped to the triangle, becomes the straight line shape by the toper.
Preferably, a limiting spring is arranged at the top of the distance adjusting shaft and is rotatably connected with the distance adjusting shaft.
Preferably, the side of the distance adjusting shaft is provided with an arc-shaped bulge, and when the blocking rod moves towards the direction far away from the die center, the arc-shaped bulge arranged on the side of the distance adjusting shaft is extruded, so that the distance adjusting shaft moves downwards and is not rotated when being separated from the rotating shaft.
Preferably, the one-way clamping plate is meshed with the bottom of the blanking die in a one-way mode, and the meshing direction is towards the die center.
(III) advantageous effects
Compared with the prior art, the invention provides the plate punching die capable of preventing burrs from occurring, and the plate punching die has the following beneficial effects:
1. this can prevent panel cut-out press that burr appears scrapes the cooperation of pole through pressure-sensitive switch and triangle and uses, when punching a hole to panel, when appearing the clearance between drift and blanking die hole, after the drift extrudees panel break-through, the burr can appear by the perforation department lower limb in panel.
When the drift gets into the blanking mould in, can produce the extrusion to the pressure switch, make the motor of control power screw rod start, the screw channel internal rotation that the power screw rod was seted up inside the blanking mould, and remove to the pivot direction gradually, meanwhile, the stripper bar is extruded by the pressure switch, power-off rod synchronous motion, when clearance does not appear between drift and the blanking mould hole, the stripper bar drives disconnected pole and removes and extrude the conducting rod, the conducting rod is extruded to bracing piece one end emergence deflection and breaks away from each other, lead to the motor outage, the power screw rod is not rotating.
When the clearance appears between drift and the blanking die hole, the outage pole can't produce the extrusion to the conducting rod, power screw rod can continue to rotate, contact with the pivot and produce the meshing transmission afterwards, the pivot rotates the centrifuging tube that drives the top and rotates, under the effect of centrifugal force, the centrifuging rod drives the triangle and scrapes the pole and remove to keeping away from the axle center direction, when the pole breaks away from the centrifuging tube is scraped to the triangle, because the inside extrusion spring that sets up of pole is scraped to the triangle, the triangle scrapes the pole and takes place to deflect, become the straight line shape by the toper, its top and panel bottom are equal height, and be located the below of the department edge of leaving a hole, the pivoted triangle scrapes the pole and can strike off the uncooled burr in panel department edge that punches a hole, thereby reached when the clearance appears in drift and blanking die, the effect.
2. The plate punching die capable of preventing burrs is used by matching the magnet and the blocking rod, because the inner hole of the blanking die expands, the symmetrical magnets arranged in the blanking die are separated from the action point due to the enlarged distance, and the blocking rod does not move towards the die center under the action of the extension spring arranged on the side surface under the mutual repulsion, the adjusting rod moves upwards under the action of the top limiting spring and is inserted into the bottom of the rotating shaft to synchronously rotate, under the action of centrifugal force, the impact rod continuously impacts the lever, so that the lever continuously drives the one-way clamping plate to move under the action of the supporting rod arranged on the side surface of the lever, because the one-way clamping plate is engaged with the bottom of the blanking die in one way, the one-way clamping plate can drive the blanking die to move towards the die center, when the magnet moves to the inner hole of the blanking die and is normal, the symmetrical magnets reach an action point, and the magnets repel each other.
Under the effect of magnetic force, stop the pole and remove to keeping away from the mould heart direction, extrude the arc arch that the distance adjusting axle side set up for the distance adjusting axle moves down, breaks away from the pivot and is not rotating, thereby has reached the effect of automatic recovery blanking die hole size.
