Abstract

The utility model is a horizontal swing cross-cut sawing machine, which is the improvement of the current large horizontal saws. The arch is pivot connected with the center hole of the arch through the central rotating shaft of the slide block. The slip mechanism of one side of the arch is equipped with a swing mechanism composed of a servo-actuator, a decelerator, a screw mandrel, a sliding table working in with the screw mandrel, a dovetail lead rail fixed to the slide plate and working in with the dovetail groove. A sliding block working in coordination with the sliding table and the sliding groove is arranged at the arch. The utility model enables the band saw to swing repeatedly within an inclination angle, which changes the traditional straight-line sawing. Therefore the utility model reduces the abrasion of the band saw and extends the life span and sawing efficiency. The utility model is applied to the large scale steel factories or molding manufactories.

Description

Horizontal swing saw

Affiliated technical field

The utility model relates to machining equipment, and particularly a kind of horizontal swing saw is fit to large shape or Mould Machining factory and uses.

Background technology

The band saw sawing machine is a kind of process equipment that cuts large shape, and known horizontal swing saw is made up of workbench, horizontal shelf, sawing mechanism and walking mechanism.The saw band of sawing mechanism is installed on the shelf by on motor and reduction box driving wheel driven and the driven pulley, and the feed of walking machine is to drive two rhizoid bars respectively and rotate and the slide plate that is attached thereto is walked about along the rolling guide on workbench two root posts drive the shelf that is attached thereto and move up and down and realize by being installed on two motors on the crossbeam and reduction box.This sawing machine its saw band when the sawing workpiece is straight-line, and the length that saw band contacts with workpiece is exactly the thickness or the width of workpiece.There is following weak point in this sawing machine always: first band saw and workpiece contact-making surface are big, are difficult for cooling, wearing and tearing easily, and service life is short; It two is that saw kerf departs from easily, makes the workpiece of sawing out produce angle; It is three when being the too thick workpiece of sawing, because contact-making surface is big, therefore heating easily will reduce feed speed, influences stock-removing efficiency.

Summary of the invention

The purpose of this utility model is to solve the problem that existing band saw sawing machine exists, and a kind of band saw long service life is provided, the high and straight horizontal swing saw of saw kerf of sawing efficient.

Above-mentioned task is that such mode realizes: this sawing machine comprises workbench, place two root posts and rolling guide on the workbench, place crossbeam and two walking mechanisms that constitute by motor reducer and screw mandrel of column end face, be positioned at the crossbeam below with the inboard slide plate that contacts and be connected with rolling guide in its two ends with screw mandrel, the shelf that is connected with slide plate and placing on the shelf by motor, decelerator, driving wheel, the sawing mechanism that driven pulley and band saw constitute, it is characterized in that shelf be by sliding central rotating shaft and its centre bore articulate and slip together, on the slide plate of shelf one side, also be provided with one by servomotor, decelerator, screw mandrel, the slide unit that cooperates with wire rod thread, cooperate and be fixed in the swing mechanism of the dovetail guide composition on the slide plate with the slide unit dovetail groove, on shelf, be provided with a slide block that cooperates with the slide unit chute.

The purpose of this utility model also can take following measure to realize:

Both sides are that radiuses such as center have four deep-slotted chip breakers with the centre bore on shelf, are provided with four guide fingers that cooperate with deep-slotted chip breaker on slide plate.

The screw mandrel of described swing mechanism is a ball screw, to reduce screw mandrel because of the wearing and tearing that frequent rotation is produced, improves its service life.

The pendulum angle of the utility model saw band is suitable with 2 °.

The utility model is work like this: as above-mentioned improvement project, because the utility model is provided with the band saw swing mechanism, when band saw carries out work, allow the continuous positive and negative rotation of servomotor, make the also continuous positive and negative rotation of screw mandrel by decelerator, the slide unit that is threaded is with it moved up and down along dovetail guide, by the chute of slide unit and the slide block on the shelf, make shelf do slight swing around central rotating shaft, driving band saw swing repeatedly in a less inclination angle scope of sawing mechanism, is to carry out under swinging condition thereby make the sawing work of band saw.The contact area of band saw and workpiece when therefore having reduced sawing, cooling easily, wearing and tearing reduce, improved the service life of band saw, and can improve sawing speed, increased work efficiency, the phenomenon of meanwhile also avoiding saw kerf to depart from takes place, and overcomes the deficiency of existing band saw sawing machine effectively.

Fig. 3 is the amplification view at B place among Fig. 1.

The specific embodiment

Referring to figs. 1 through Fig. 2, the utility model includes workbench 1, places column 2 and rolling guide 3 on the workbench 1, places walking mechanism that the crossbeam 4 of column 2 end faces and two are made of motor 5, decelerator 6 and screw mandrel 7, is positioned at that its two ends, crossbeam 4 belows are inboard to be contacted with rolling guide 3 and the slide plate 8 that is connected with screw mandrel 7, the shelf 9 that is connected with slide plate 8 and the sawing mechanism that is made of motor 10, decelerator 11, driving wheel 12, driven pulley 13 and band saw 14.

Shelf 9 of the present utility model is to articulate with slide plate 8 by the central rotating shaft 15 of slide plate 8 and its centre bore 16 to link together, and whole shelf 9 can be around central rotating shaft 15 swings.Slide unit 20 that the swing mechanism of shelf 9 is threaded by servomotor 17, decelerator 18, screw mandrel 19, with screw mandrel 19 and the dovetail guide 21 that cooperates with slide unit 20 are formed, and are arranged on the slide plate 8 of shelf 9 sides.The slide block 23 that cooperates with slide unit 20 side guide grooves 22 is arranged on the shelf 9.On shelf 9, be that radiuses such as center have four deep-slotted chip breakers 24, the corresponding position is provided with four guide fingers 25 that cooperate with deep-slotted chip breaker 24 on slide plate 8 with central rotating shaft 15 centers.The pivot angle of shelf 9, promptly the pendulum angle of band saw 14 is suitable with 2 °.

26 is that workpiece, 27 is the band saw strainer among Fig. 1.
