Abstract
The utility model relates to a stepless adjustment type shearing device and belongs to the technical field of cold bend board machining equipment. The stepless adjustment type shearing device comprises a rack and a shearing part. The rack comprises a cross beam and two side beams; the shearing part comprises oil cylinders, a lower cutter piece and an upper cutter driven by the oil cylinders; the oil cylinders are arranged on the cross beam, the upper cutter is in an M shape and arranged below the oil cylinders, and the lower cutter piece is arranged below the upper cutter. According to the stepless adjustment type shearing device, the upper cutter is in the M shape with a symmetrical structure, the two cylinders drive the upper cutter to move in a bidirectional mode, therefore, a cutting point can be located in the center of a board all the time, stepless adjustment type shearing can be achieved, machining can be completed only through one specification of upper cutters, the amount of waste is small, and cutting accuracy is higher.
Description
Technical field
The utility model relates to a kind of stepless adjustable shear, belongs to clod wash sheet machining apparatus technical field.
Background technology
The occasions such as building purlin commonly used mainly is divided into two kinds of C type and Z-types, the moulding of existing building materials purlin mainly is by smoothing, cold roll forming, punching, shearing rear support C type or Z-shape steel, wherein, conventional cutting operation is mainly sheared by Crocodile type and is finished, and in the shear history, need to use three cutters, respectively a shear knife and two side tools, it is mobile wherein only having a side tool, by the cooperation of shear knife and side tool, realizes cutting work.
Although this mode is easy, but in cutting process, it is the moving direction of the moving direction of side tool and sheet material and inconsistent movably, therefore, after removable side tool moved to certain angle, namely specification was above the upper slitter that will change different size behind the certain size, otherwise will produce misalignment angle, cutter is offset, twists, and causes that the sheet material otch is uneven, cutting edge roundness damages, and can't finish processing work.
Have based on this, make the utility model.
The utility model content
For solving the problems of the technologies described above, the utility model provides the stepless adjustable that a kind of shear precision is high, waste material is few shear.
For achieving the above object, the technical scheme taked of the utility model is as follows:
The stepless adjustable shear comprises frame and cut part, and frame comprises crossbeam and two curb girders, described cut part comprises the upper slitter of oil cylinder, lower cutter spare and hydraulic oil cylinder driving, and oil cylinder is installed on the crossbeam, and upper slitter is the M type, upper slitter is installed in the oil cylinder below, and lower cutter spare is positioned at the below of upper slitter.
For realizing better result of use, further arranging of technique scheme is as follows:
Described oil cylinder is two, is installed in respectively the upper end of upper slitter.
Described lower cutter spare comprises two vertical cuttves and a horizontal cutter, horizontal cutter is installed on the crossbeam by adjustable plate one and adjusting screw(rod), can realize moving up and down of horizontal cutter by adjustable plate one and adjusting screw(rod), two vertical cuttves are installed on the curb girder on frame both sides by adjustable plate two, screw mandrel and upper rail and lower guideway respectively, and screw mandrel drives vertical cutter side-to-side movement in upper rail and lower guideway.
Adopt the utility model without the skew shear, when sheet material is delivered to the cut part, start oil cylinder, the hydraulic oil cylinder driving upper slitter moves down, by adjusting screw(rod) adjustable plate one is moved up and down, make adjustable plate two move left and right by screw mandrel, regulate lower cutter spare, guarantee that sheet material just can be fixed between lower cutter spare and the upper slitter, can finish cutting work.In the utility model because upper slitter is the M shape of symmetrical structure, lower cutter spare can about, move left and right, thereby realize electrodeless adjusting.
Adopt shear of the present utility model, upper slitter is the M type of symmetrical structure, two air cylinder driven upper slitter way movings, guarantee that cut point is positioned at the center of sheet material all the time, can realize stepless adjustable shearing work, only need a kind of upper slitter of specification can finish processing work, waste material is few, and cutting accuracy is higher.
