Abstract
The invention discloses equipment for a flat steel shaping and machining set, in particular to cross cut shears for slitting and leveling flat steel. The cross cut shears comprise a stand, wherein the stand is provided with a hold-down hydraulic cylinder; the two sides of the stand are provided with upright posts; the upright posts are provided with hydraulic pressing mechanisms; a piston rod of the hold-down hydraulic cylinder is connected to a sliding stand; the sliding stand is arranged on a guide post; the two ends of the guide post are connected to the stand; the stand is provided with a lower knife rest; the lower knife rest is provided with a lower blade; the lower end of the sliding stand is provided with an upper blade; the upper blade consists of two blades which are arranged in a reverse V shape; the hydraulic pressing mechanism comprises a fixed cross beam; the fixed cross beam is provided with a pressing hydraulic cylinder; the two sides of the pressing hydraulic cylinder on the fixed cross beam are provided with guide rods; the lower parts of the pressing hydraulic cylinder and the guide rods on the two sides are provided with pressing blocks; and the lower plane of the pressing block is lower than the lower end of the upper blade. Because the upper blade is arranged by adopting a reverse V-shaped design, a plate is uniformly stressed during the shearing process and the problems of easy lateral bending of a spring, easy pass-line deflection of the plate and the like of a conventional normal oblique blade cutting mechanism during the pressing of the spring are prevented; and thus the working stability of the cross cut shears is ensured and the shearing quality and the service life of the blade are greatly improved.
Description
Technical field
The present invention relates to a kind of equipment of band steel processing and forming unit, be specially the hydraulic pressure cross cut shears.
Background technology
Existing hydraulic pressure cross cut shears, for common oblique sword is cut, under the driving effect of hydraulic cylinder, utilize spring structure that sheet material is compressed, cutter, bottom knife are sheared the cut-out processing that realizes sheet material, the shortcoming of this structure is, in frequent shear history up and down reciprocatingly, when spring produces fatigue failure or axial load when excessive, spring can produce lateral thrust and loss of stability, and this common oblique sword is cut when cutter is depressed shearing, and is easier of angle direction sideslip, shearing quality is affected, and cutter is sustained damage.
Summary of the invention
At the problems referred to above, it is more stable to the invention provides a kind of shear history that can make, and improves shearing quality, and can effectively protect the cross cut shears for slitting and leveling flat steel of cutter.
Technical scheme of the present invention is:
A kind of cross cut shears for slitting and leveling flat steel, comprise frame, frame is equipped with hydraulic cylinder for reduction system, and the both sides of frame are provided with stand, stand is provided with the hydraulic pressure hold-down mechanism, the piston rod of hydraulic cylinder for reduction system is connected on the sliding frame, and sliding frame is arranged on the guide pillar, and the two ends of guide pillar are connected on the frame, frame is provided with lower slide, lower slide is provided with bottom knife, and the lower end of sliding frame is equipped with cutter, and cutter is made up of two blades that are the splayed installation.
Described hydraulic pressure hold-down mechanism comprises fixed cross beam, be equipped with on the fixed cross beam and compress hydraulic cylinder, the both sides that compress hydraulic cylinder on the fixed cross beam are provided with guide rod, and the bottom that compresses hydraulic cylinder and both sides guide rod is provided with briquetting, and the lower plane of briquetting is lower than the lower end of cutter.
Beneficial effect: the cutter mounting means among the present invention, owing to adopt the splayed design, make sheet material stressed even in shear history, avoided existing common oblique sword shearing machine structure, by spring compression the time, spring easily produces lateral bending, and problems such as sideslip easily take place sheet material, shearing quality and cutter life-span are affected, thereby have guaranteed the job stability of cross cut shears, improved shearing quality and blade service life greatly.Employing compresses hydraulic cylinder and drives guide rod to drive briquetting descending, and briquetting compresses sheet material, and hydraulic is stable, makes sheet material be difficult for sideslip more.
