Abstract
The invention discloses a toothholder stamping die of a brake. The toothholder stamping die of the brake comprises a bent male die, and a female die matched with the bent male die, wherein a lower template is arranged below the female die; a locating plate is arranged at the lower part; a die cavity is arranged inside the female die; a head part plate is arranged inside the die cavity; a post rod capable of ejecting the head part plate upwards is arranged below the head part plate; two grooving beads are arranged at two sides of the bottom part of the bent male die; the heights of the groove beads are 0.2-0.4mm, and the widths are 2-3mm. According to the toothholder stamping die of the brake disclosed by the scheme in the invention, firstly, two grooves are stamped on the parts in a stamping process by providing the two grooving beads at the bottom part of the bent male die; and the grooving beads are embedded into corresponding grooves. Therefore, reduction of bending springback and excursion when the part is stamped again is facilitated; high verticality requirements of the part are guaranteed, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of brake toothholder stamping die.
Background technology
Toothholder is the important structure part in the product brake components, the employing spring steel is made, owing to use the needs on the function, two arms after the requirement bending are vertical with the baseplane, guarantee that perpendicularity requires 0.1mm, this toothholder stamping die comprises the bending punch in the prior art, the die that is used with the bending punch, when bending, because be subjected to force unbalance during spares bend, both sides are diastrophic inconsistent, cause skew and the resilience of part, its two arm and baseplane perpendicularity can only reach about 2mm, cause product percent of pass low, use in the brake if above-mentioned toothholder packed into reluctantly, then can affect the serviceability of brake.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed the resilience of a kind of minimizing part, guaranteed the brake toothholder stamping die of machining accuracy.
Technical solution of the present invention is achieved in that a kind of brake toothholder stamping die, comprises the bending punch, the die that is used with the bending punch; Described die below is provided with lower bolster, and the below is provided with location-plate; Be provided with die cavity in the described die; Be provided with the head part plate in the described die cavity, described head part plate below is provided with the push rod that the head part plate can be made progress jack-up, and described bending punch two bottom sides is provided with two and cuts the geosynclinal convex rib; The described height that cuts the geosynclinal convex rib is 0.2～0.4mm, and width is 2～3mm.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of brake toothholder stamping die of the present invention, cut the geosynclinal convex rib by being provided with two in bending punch bottom, when punching press, first part punching is gone out two grooves, cutting the geosynclinal convex rib embeds in the respective grooves, bending springback and skew when being beneficial to reduce part continuation punching press guarantee the higher perpendicularity requirement of part, and have significantly improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the punching press pre-structure schematic diagram of a kind of brake toothholder stamping die of the present invention;
Accompanying drawing 2 is structural representation after the punching press of a kind of brake toothholder stamping die of the present invention;
Wherein: 1, bending punch; 2, die; 3, lower bolster; 4, location-plate; 5, die cavity; 6, head part plate; 7, push rod; 8, cut the geosynclinal convex rib; 9, part.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is a kind of brake toothholder stamping die of the present invention, comprises bending punch 1, the die 2 that is used with bending punch 1; Described die 2 belows are provided with lower bolster 3, and the below is provided with location-plate 4; Be provided with die cavity 5 in the described die 2; Be provided with head part plate 6 in the described die cavity 5, described head part plate 6 belows are provided with the push rod 7 that head part plate 6 can be made progress jack-up, and described bending punch 1 two bottom sides is provided with two and cuts geosynclinal convex rib 8; The described height that cuts geosynclinal convex rib 8 is 0.2～0.4mm, and width is 2～3mm, is preferably, and the height that cuts geosynclinal convex rib 8 is 0.3mm, and width is 2mm.
Before the punching press, mold open, bending punch 1 disengages with die 2, and to exceeding plane on the die 2, bending punch 1 descends and cooperatively interacts with head part plate 6 push rod 7, with two groove punching presses on the product out with head part plate 6 tops; Subsequently part is carried out punching press, bending punch 1 continues to descend, and head part plate 6 descends thereupon, finally finishes spares bend under the acting in conjunction of bending punch 1 and head part plate 6, die 2.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
