Technical field

The utility model relates to cutting machine, in particular to a kind of cutter device of cutting machine.

Background technique

It is frequently necessary to cut raw material during machine components processing, and raw material are usually cylindrical Bar, and cutting for bar is generally carried out by cutting machine.

Currently, the Chinese invention patent that Authorization Notice No. is CN100393461C discloses a kind of rod material automatic cutting machine Cutting mechanism, including motor and the blade being fixed on machine shaft, blade is at the discharging of cutting machine；Further include one to hang down Straight setting and the connecting rod that opposite can be moved up and down with fuselage, the upper end of connecting rod and motor are connected, and lower end press can in a card tooth With the edge of the cam of rotation；Go out to be equipped with a supporting block in the discharging of cutting machine, a cross bar is laterally set in fuselage, A compression bar is vertically arranged in fuselage, there are the strut kong passed through for bar, lower end and the cross bar phase of compression bar in the upper end of compression bar Connection.

Cutting machine with this cutting mechanism, when cutting bar, mainly moving up and down come to stick by blade What material was cut, but this cutting machine is found during use, during cutting, Cutting Length is bar Judged by the experience of worker, therefore is easy to cause mismachining tolerance.

Utility model content

The purpose of the utility model is to provide a kind of cutter devices of cutting machine, can be cut by mechanical structure to bar It cuts length to be adjusted, reduces the error that artificial judgment generates, to achieve the purpose that improve bar segmentation precision.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of cutting of cutting machine Device is provided in the rack for adjusting bar Cutting Length including rack, the cutting mechanism being slidably connected in rack Regulating mechanism, the regulating mechanism includes the fixing seat being fixed in rack, the locating piece being slidably connected in fixing seat, solid It is described due in rack and being located at mounting base of the fixing seat far from bar side, the adjusting screw rod being threadedly connected in mounting base One end that adjusting screw rod passes through mounting base is rotationally connected on locating piece, and the direction of motion of the locating piece is parallel to bar Feedstock direction.

By using above scheme, when needing the Cutting Length to bar to be adjusted, adjusting screw rod is rotated first, is adjusted Section screw rod its distance between mounting base and fixing seat during rotation can change；Since adjusting screw rod passes through One end of mounting base is rotationally connected on locating piece, therefore adjusting screw rod will drive locating piece in positioning seat in the process of movement Upper generation sliding, and then cause the variation of distance between locating piece and saw blade；And the distance between locating piece and saw blade, it is exactly stick The Cutting Length of material, therefore the position for adjusting locating piece can adjust the Cutting Length of bar；Have certainly due to being threadedly coupled Lock property, therefore in the case where not rotating adjusting screw rod, the distance between locating piece and saw blade are fixed, the i.e. cuttings of bar Length is also fixed, therefore the bar being cut into this way compares the bar for manually judging to be cut into, and size is more It is close, therefore can be improved the cutting accuracy of bar.

The utility model is further arranged to: the cutting mechanism includes the pedestal being slidably connected in rack, fixation In on pedestal cutting motor, reduction gear box, be fixed on reduction gear box output shaft on saw blade, be set in rack and Feed component for driving bar to move towards saw blade is set in rack and for driving pedestal along perpendicular to bar length The feeder assembly of linear reciprocating motion is done in direction, and linkage belt wheel, the reducing gear are fixed on the output shaft of the cutting motor It is fixed with passive belt wheel on the input shaft of roller box, is linked between the linkage belt wheel and passive belt wheel by belt.

By using above scheme, when needing to cut bar, starting is fed component first, and bar transportation is arrived In cutting work station；Then start cutting motor, cutting motor will drive saw blade rotation during starting；Then restart into To component, feeder assembly drives entire pedestal to move towards bar, and pedestal in the process of movement, will drive saw blade and bar produces Raw contact, and it is gradually that bar is sawed-off, to achieve the purpose that be split bar.

The utility model is further arranged to: the feed component is separate including being fixed in rack and being located at fixing seat The rotation seat of mounting base side, be rotationally connected on rotation seat and along the feedstock direction of bar distribution feed roller, pass through binder Component is liftably slidably connected to the nip rolls on rotation seat, between the side wall being recessed inwardly on the nip rolls and feed roller Be formed with for for bar pass through to material space, the nip rolls is set on the rack between adjacent two feed rollers It is equipped with the driving assembly for driving feed roller to rotate.

By using above scheme, rotation seat is used to install for feed roller and nip rolls, and driving assembly is for driving feed Roller rotation when clamping bar by feed roller and nip rolls, can be driven towards saw blade by feed roller and move, so that bar is in quilt After segmentation, charging can be continuously replenished；And set nip rolls between adjacent two feed rollers, so that bar is being given When material roller and nip rolls are clamped, feed roller and nip rolls can form at least two supporting points on the length direction of bar, because This can form bar and limit, so that bar be made to be not easy to generate offset during cutting.
