Abstract
The utility model provides a swing band saw machine, which is characterized by improvement on prior large vertical saw machine that a connecting board is arranged between a bow rack and a roller plate that are articulated through a center axle; the roller plate in one outer side of the connecting board is provided with a swing mechanism that drives a boring bar by way of a servo motor and a deceleration box and makes the boring bar match and move up and down in the side stage of a swallow-tail guiding rail; through the slide groove in the slide stage flank, the slide block of the connecting board is driven to move up and down to lead the bow rack repetitively to rotate around the center axle, so that the band saw is driven to swing repeatedly within a relatively small slant angle, traditional band saw straight line sawing and cutting style is changed, band saw abrasion is reduced, and service life and sawing efficiency is enhanced. The utility model is applicable in large steel or die factories.
Description
Affiliated technical field
The utility model relates to the sawing machine of machining equipment, and particularly a kind of swing band saw sawing machine is fit to large shape factory or template processing factory and uses.
Background technology
The band saw sawing machine is a kind of process equipment that cuts large shape.Known band saw sawing machine is made up of workbench, shelf, sawing mechanism and walking mechanism.The saw band of sawing mechanism is installed on the driven saw wheel and the active saw wheel by motor and reduction box drive of shelf.The roller of walking mechanism is installed on the roller plate and rear pillar of front, shelf bottom, walk along the guide rail on the support by servomotor and reduction box driving rolls, the saw band on the shelf is cut along the material that the gap between the workbench of front and back is opposite in the work of front and back.This sawing machine its saw band when the sawing workpiece is moving to be 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 saw band 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 provides a kind of saw band long service life, sawing efficient height and saw kerf straight swing band saw sawing machine.
Above-mentioned task realizes by this way: this sawing machine includes workbench, shelf, saw band, driven saw wheel, the active saw wheel, motor and reduction box, roller plate, roller, servomotor and reduction box, guide rail and support, it is characterized in that connecting plate in addition, slide unit, screw mandrel, slide block, dovetail guide, the swing mechanism that servomotor and reduction box constitute, connecting plate places between shelf and the roller plate and with shelf and links together, connecting plate and shelf are hinged by central shaft and roller plate, dovetail guide is located on the roller plate in the connecting plate outside, slide unit cooperates with dovetail guide and places on the dovetail guide with the dovetail guide groove of its bottom, place in the slide unit with the slide unit threaded-fit screw rod, its termination is connected with the reduction box of servomotor, and the slide block that is located at connecting plate one end places in the chute on the slide unit.
The purpose of this utility model also can take following measure to realize:
Can be affixed on the roller plate in order to guarantee that connecting plate has, center with the connecting plate central shaft is that the center of circle respectively is provided with a block pressur plate on four angles of same radius, and is connected with nut by the through hole that a bolt passes the circular hole of pressing plate through hole, connecting plate and roller plate pressing plate, connecting plate and roller plate are linked together.
Described screw mandrel adopts ball screw, improves service life to reduce wear.
The angle of oscillation 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 saw band wabbler mechanism, when saw band is carried out work, the just continuous positive and negative rotation of servomotor, make the also continuous positive and negative rotation of screw mandrel by reduction box, the slide unit that is threaded is with it constantly moved up and down along dovetail guide, and the guide groove by the one side makes the slide block that cooperates with it and be located on the connecting plate make arcuate movement up and down around the center of central shaft again.Because slide block is fixed on the connecting plate, connecting plate and shelf are also rotated repeatedly around the central shaft center, driving saw band swings in a less inclination angle scope repeatedly, thereby the sawing work of saw band is carried out under swinging condition, the contact area of saw band and workpiece when therefore having reduced sawing, cooling easily, wearing and tearing reduce, improved the service life of saw band, and can improve sawing speed and increase work efficiency, the phenomenon of meanwhile also having avoided saw kerf to depart from takes place, and overcomes the deficiency of existing saw band sawing machine effectively.
