The utility model discloses a die for cutting off round steel on a large scale. The die for cutting off round steel on a large scale is installed on a universal crank press to operate, comprises a cutting-off blade fixed on an upper die, a round steel cutting-offf length regulating screw rod fixed on a lower die, an adjustable cutting-off concave die and the like, and has no cut waste materials; and the cutting-off production efficiency is equal to operating frequency at the press continuous operating mode. The round steel cutting-off die is simple in structure, is high in production stability, and is easy to implement. The mass one-piece weight error of the cut cross section flatness of cut steel bars are suitable for the first raw material cutting-off working procedure of mass production of die forging, extrusion and the like. The die for cutting off round steel on a large scale provided by the utility model also can be used for cutting off other round steel.
Description
Affiliated technical field
The utility model relates to a kind of steel cutting mould, is installed on the general crank press to work.This mould cuts off batch single-piece weight error and the section flatness of rod iron, and the first raw material that is applicable to the batch productions such as die forging, extruding cuts off operation, also can be used for the cut-out of other round steel.
Background technology
Present known steel cutting mould is to be made of upper and lower mould.Wherein patrix is comprised of die shank, cutting knife pressing plate, cutoff tool etc.Counterdie consists of counterdie cut-out length adjusting mechanism by the monoblock buting iron of removable location, adjusts the round steel shearing length by the position of mobile monoblock buting iron; And the counterdie die mechanism that is formed by die, die bearing; This shearing length guiding mechanism and die mechanism and counterdie seat board connect to form the part of the lower die.Working clearance during installation between adjustment and assurance die side and the cutoff tool side.During work, round steel is sent into by die, and the round steel front end contacts with the monoblock buting iron determines shearing length, and then the patrix cutoff tool moves downward and finishes the round steel cut-out.But the tight fit of die and die bearing makes the assembling difficulty, can't adjust owing to the die position simultaneously, so that the working clearance between die side and the cutoff tool side is adjusted difficulty; Adjust the round steel shearing length by the running fix of monoblock buting iron and also be not easy to operation.
The utility model content
For the working clearance that overcomes between existing steel cutting mould die side and the cutoff tool side is adjusted difficult problem, and the operation inconvenience problem of adjusting the round steel shearing length by the running fix of monoblock buting iron, the utility model provides a kind of steel cutting mould, this steel cutting mould is not only regulated the working clearance between die side and the cutoff tool side easily, and just the shearing length adjustment is simplified.
The technical scheme that its technical problem that solves the utility model adopts is: combining structure is adopted in the part of the upper die, comprise by cutoff tool, cutting knife pressing plate, tool rest, die shank and forming, be connected to become the part of the upper die by screw thread pair, the impulsive force of cutoff tool directly acts on tool rest during work, and is replaceable when the tool rest deformed damaged.Adjusting screw(rod), locking nut and adjustment seat form the shearing length guiding mechanism of counterdie, this mechanism is connected with the counterdie seat board by screw thread pair, the round steel end face of sending to from die and adjusting screw(rod) end contact are to determine shearing length, adjust its endface position by the rotation adjusting screw(rod), and make adjusting screw(rod) location by screwing locking nut, realize the shearing length adjustment; Die cooperates with the die bearing by the opening gripping sleeve diametrically, and it is fastening to carry out radiai adjustment by lock-screw and locking nut.The axial location of die is by axial cover and swivel nut and die bearing screw thread pair is connected and fixed and by nut check; the working clearance of cutoff tool side and die side is regulated when realizing work thus; this swivel nut tail end is connected with nut and consists of support to cutting off round steel; be convenient to feeding operation, consist of thus the die mechanism of counterdie.This die mechanism connects by screw thread pair counterdie seat board, jointly consists of the part of the lower die with the shearing length guiding mechanism.Part of the upper die and part of the lower die consist of steel cutting mould.Determine the round steel shearing length by the distance of adjusting screw(rod) end face and die side during work, adjust cutoff tool circular arc edge of a knife center line crossing and vertical with the die longitudinal center line, adjust the working clearance between cutoff tool side and the die end face, mould can be started working.One of every cut-out is by manually the round steel axial feeding being pushed against the adjusting screw(rod) end face.
The beneficial effects of the utility model are, when finishing round steel and cutting off, the shearing length adjustment are realized by adjusting screw(rod), make easy and simple to handle; The die that can move axially the location has simultaneously made things convenient for the adjustment of cutoff tool and die side working clearance.Mold integral is simple in structure.
