Abstract
The utility model discloses a waste separation device which comprises an upper waste separation knife block and a lower waste separation knife block; the lower bottom surface of the upper waste separation knife block is a first inclined plane; a first knife edge used for cutting off a processed material is arranged at one end of the first inclined plane; the main body of the upper bottom surface of the knife unloading block comprises a second inclined plane and a third inclined plane; a second knife edge used for cutting off waste is arranged at the upper end of the second inclined plane; the second knife edge is connected with the third inclined plane; an acute angle is defined by the second inclined plane and the third inclined plane; and a gap is reserved between the lower knife block and a lower male die on which the processed material is placed. Through the adoption of the waste separation device, the waste iron scale left at the waste edge part can be decreased, and the condition that the iron scale is absorbed in the die body to crush the parts under the magnetic effect of the cutting edges is avoided.
Description
Technical field
The utility model relates to a kind of punching die structure, refers in particular to a kind of waste material separating device.
Background technology
At present, in stamping parts transfer matic production process, every batch of production has waste material to weigh part wounded, causes the follow-up employee work amount of reprocessing to strengthen.Its subject matter is exactly that die trimming waste material separation circuit brings the waste material iron filings to be retained in counterdie waste material cutting edge position always, in the part production process, the friction of upper and lower mould cutting edge gap produces certain frictional static, makes iron filings bring under the cutting edge magnetic action and weighs processed machined material in die ontology wounded.In production process, first inspection finds that part has impression just to stop the line wiping die, causes automated production rhythm slow, and production efficiency can't satisfy the production capacity designing requirement.China Patent Publication No. CN201841201U, open day on May 25th, 2011, name is called waste material and the inserts isolating construction that discloses in the utility model patent of " waste material in a kind of insert hole punching and inserts isolating construction " in a kind of insert hole punching, and it is included on the lower mold holder of perforating die by screw and straight pin be fixedly connected die block, backing plate and add-in card; Die is fixed by screws on backing plate; Location-plate is set above die, and location-plate is positioned on the lower mold holder of perforating die by screw attachment, is arranged on that spring in backing plate ejects location-plate and higher than die.Fix movable supporting plate and rubbermeter with lower nut and lower bolt under the lower mold holder of perforating die.The movable push bar that runs through location-plate and lower mold holder also is set; Push rod one end top pressing palette; Divide into top set bar fixed head and push pedal at backing plate, at least one the waste material push rod that runs through die is fixed on the push rod fixed head; Between push pedal and supporting plate, movable rod is set; The inserts push rod that is fixed on the push rod fixed head also is set, and the length of inserts push rod is slightly longer than the length of waste material push rod.Owing to adopting the structure that ejects for twice, waste material and inserts separation problem have been solved.But this isolating construction just can separate waste material effectively, but still can not solve the problem that easily produces iron filings at the edge of a knife.
The utility model content
The purpose of this utility model is to overcome in prior art die trimming waste material separation circuit to bring the waste material iron filings to be retained in counterdie waste material cutting edge position to cause the defective that weighs processed machined material wounded always, and a kind of waste material separating device that can effectively reduce the waste material iron filings that remain in waste material cutting edge position is provided.
The purpose of this utility model is to be achieved by following technical proposals:
A kind of waste material separating device is characterized in that, comprises cutter piece under waste material separating knife upper cutter block and waste material separating knife, and the bottom surface of upper cutter block is the first inclined-plane, and an end on inclined-plane is for being used for cutting off the first edge of machined material; The main body of the upper bottom surface of lower cutter piece comprises the second inclined-plane and the 3rd inclined-plane, and the upper end on the second inclined-plane is for being used for cutting off the second edge of waste material, and the second edge is connected with the 3rd inclined-plane, and the second inclined-plane and the 3rd inclined-plane consist of wedge angle; Lower cutter piece and lay between the counterdie punch of machined material and be provided with the space.Mould is divided into patrix die and counterdie punch, at first upper mould moves by stamping machine and moves downward, machined material is cut stay the live part of machined material on punch, formed waste material under upper punch, waste material length is long owing to producing, stuck at the waste material runner when easily causing waste material slide-down, cut off therefore carry out waste material by lower waste knife piece, iron filings enter reject chute along the 3rd inclined-plane by the space.
As a kind of preferred version, lower cutter piece and the distance of laying the space between the counterdie punch of machined material are 2mm-4mm.The design of 2mm-4mm guarantees that the waste material iron filings can enter reject chute by the space along the 3rd inclined-plane.
As a kind of preferred version, the angle of the 3rd inclined-plane and horizontal plane is 40 °-50 °.This angle guarantees that waste material can slide smoothly along the 3rd inclined-plane.
As a kind of preferred version, the angle of the first inclined-plane and horizontal plane is 30 °-40 °.This angle has improved the approach of upper cutter block edge, and the assurance iron filings can not brought in die ontology.
The beneficial effects of the utility model are that waste material separating device effectively reduces the waste material iron filings that remain in waste material cutting edge position, avoids iron filings to bring under the cutting edge magnetic action and weighs part in die ontology wounded.
