The invention relates to a die used for upward hole flanging; the die comprises a lower die seat and an upper die seat; a guiding column which is arranged on the lower die seat is matched with a guiding sleeve which is arranged on the upper die seat; the die of the invention is characterized in that a direction converter is matched with a shaft and connected on a support saddle which is fixed on the lower die seat; a polyurethane spring is arranged between the direction converter and the support saddle; the direction converter can rotate correspondingly to the shaft; a hole-flanging convex die is arranged inside a convex die guiding block and sheathed on a secondary pushing pin (20); a hole-flanging concave die is connected with the upper die seat by a nitrogen spring; a stripping attachment is arranged on the hole-flanging concave die and connected with the convex die guiding block; a pushing block is connected on the upper die seat; a shaping cutter block is arranged on the upper die seat. The die of the invention adopts the direction converter to convert the downward motion of the die into the upward motion, realizes the upward hole-flanging, as well as has the advantages of high precision, stable and reliable motion and low cost.
Description
Technical field
The present invention relates to the hole flanging mould, be specifically related to a kind of mould of flanging upward hole.
Background technology
Hole flanging is meant the processing method for stamping that utilizes mould the peritreme on the plate to be translated into vertical edge.During flanging upward hole, need eccentric swage be set at counterdie, punch is fixed on the die shoe, and this mould structure is comparatively complicated, and causes die cost to increase owing to increasing eccentric swage.
Summary of the invention
The mould that the purpose of this invention is to provide a kind of flanging upward hole, its simple in structure, easy making, production cost is lower.
The mould of a kind of flanging upward hole of the present invention comprises die shoe and upper bolster, and the guide pillar that is located on the die shoe cooperates with the guide pin bushing that is located at upper bolster; Can guarantee the closing precision of upper and lower mould like this; It is characterized in that: a direction converter cooperates with axle by bearing, and is located by connecting on the bearing by key, and bearing is fixed on the die shoe, is provided with polyamine fat spring between direction converter and bearing, and the direction converter can pivot; It is for fear of the bump of direction converter in rotary course that polyamine fat spring is set;
One hole flanging punch is positioned at the punch guide pad and is enclosed within on the secondary pushing pin, the upper end that is located at first spring of secondary pushing pin contacted with the following of punch guide pad, the last end in contact of the lower end of secondary pushing pin and one-level pushing pin, the lower end of one-level pushing pin is located by connecting on the left end of direction converter;
One hole flanging die is connected with upper bolster by nitrogen spring, and its right side cooperates with guide plate on being located at upper bolster, can slide up and down;
One stripping attachment is located on the hole flanging die, and corresponding with the punch guide pad, and stripping attachment moves downward under the effect that is enclosed within second spring on the spring guide pin relatively, thereby workpiece is released from the hole flanging die;
One pushing block is located by connecting on the upper bolster, and the right-hand member with the direction converter below it contacts;
One dressing blade piece is located on the upper bolster, and its lower end is corresponding with the upper right side of die shoe.
One honest dead piece is located on the upper bolster, and is corresponding with the hole flanging die.The effect that honest dead piece is set is to realize mould effect spacing to eccentric swage when bottom dead centre.
The present invention adopts direction switching mechanism that moving downward of mould converted to and moves upward, thereby reaches the purpose that realizes flanging upward hole; Guarantee that by the spring discharging device that is installed on the patrix eccentric swage workpiece is not stuck on the patrix; Can satisfy the needs of workpiece flanging upward hole fully, have precision height, motion stabilization is reliable, die cost is low advantage.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the state diagram before workpiece is realized flanging upward hole.
Fig. 3 is the state diagram after workpiece is realized flanging upward hole.
The specific embodiment
Referring to Fig. 1, the present invention includes die shoe 1 and upper bolster 4, the guide pillar 2 that is located on the die shoe cooperates with the guide pin bushing 3 that is located at upper bolster, and it is in order to guarantee the closing precision of upper and lower mould that guide pillars and bushes is set;
One direction converter 23 cooperates with axle 6 by bearing 7, and be located by connecting on the bearing 27 by key 25, bearing is fixed on the die shoe 1, between direction converter 23 and bearing 27, be provided with polyamine fat spring 24,26, the direction converter can be around axle 6 rotations, and it is for fear of the bump of direction converter in rotary course that polyamine fat spring is set;
One hole flanging punch 18 is positioned at punch guide pad 19 and is enclosed within on the secondary pushing pin 20, the upper end that is located at first spring 21 of secondary pushing pin contacted with the following of punch guide pad 19, the last end in contact of the lower end of secondary pushing pin and one-level pushing pin 22, the lower end of one-level pushing pin is located by connecting on the left end of direction converter 23;
One hole flanging die 15 is connected with upper bolster 4 by nitrogen spring 12, and its right side cooperates with guide plate 9 on being located at upper bolster, can slide up and down;
One stripping attachment 16 is located on the hole flanging die 15, and it is corresponding with punch guide pad 19, spring guide pin 13 is connected with spring bumper cover 11, and stripping attachment moves downward under the effect that is enclosed within second spring 14 on the spring guide pin 13 relatively, thereby workpiece is released from the hole flanging die;
One pushing block 5 is located by connecting on the upper bolster 4, and the right-hand member with direction converter 23 below it contacts;
One dressing blade piece 8 is located on the upper bolster 4, and its lower end is corresponding with the upper right side of die shoe 1.
One honest dead piece 10 is located on the upper bolster 4, and is corresponding with hole flanging die 15.
When mould is opened, ensconce under the effect of the spring 21 of hole flanging punch 18 on being enclosed within secondary pushing pin 20 in the punch guide pad 19 that is fixed on the counterdie, workpiece 28 adopts shape and alignment pin 17 location on mould.
Patrix moves downward, eccentric swage 15 is pushed down workpiece 28 under the effect of nitrogen spring 12, along with the mould continuation is descending, dressing blade piece 8 contact workpieces begin shaping, simultaneously, pushing block 5 contact directional steering devices, make it around axle 6 rotations, thereby directional steering device left end rise, by the transmission of one-level pushing pin 22 and secondary pushing pin 20, impel flanging die to move upward, thereby finish the hole flanging action.
Mould is opened, and stripping attachment 16 moves downward installation relatively under the effect that is enclosed within the spring 14 on the spring guide pin 13, thereby workpiece 28 is released from hole flanging die 15.
