Abstract
The utility model relates to a belt saw machine which relates to the sawing equipment of the mechanical industry, particularly a belt saw machine with a workpiece rotating device. The belt saw machine mainly comprises a belt saw machine seat and a saw frame composed of a saw frame body, a belt wheel and a saw belt guide bracket, and is characterized in that a workpiece rotating device is arranged on the belt saw machine seat and comprises a motor and a speed change box; the speed change box is matched with a bearing sleeve by an output end of the speed change box; the bearing sleeve is movably matched with a bearing frame. Two or more claws are arranged on the bearing sleeve used for fastening sawed workpieces. The belt saw machine has the advantages of stable running, small variation for the cutting force, high geometric accuracy for cutting the cross section, and high cutting efficiency.
Description
The utility model relates to a kind of sawing equipment of mechanical field, specifically is meant a kind of band sawing machine with Workpiece rotating device.
Existing band sawing machine all carries out sawing in the inactive state that workpiece is held, and cutting force, heat in metal cutting, the saw band length of cut of each workpiece in the sawing process has bigger variation.Especially round steel, round steel pipe, saw band is easy to generate broken belt, broken teeth during sawing, and saw band is short service life, and sawing efficient is poor.
The utility model purpose is to overcome above-mentioned defective, and sawing is the rotation sawing under the part inactive state of exchanging work, thereby a kind of band sawing machine with Workpiece rotating device is provided.
Described band sawing machine mainly comprises sawing machine seat and saw frame, and saw frame is made up of saw frame body and the belt wheel, the saw band guiding trestle that are installed on the saw frame body.The technical program is characterised in that the sawing machine seat is provided with Workpiece rotating device, and this device comprises motor and gearbox.Gearbox cooperates with bearing holder (housing, cover) by its output, and bearing holder (housing, cover) and bearing bracket stand work are joined, and the claw more than two or two is installed on the bearing holder (housing, cover), are used for fastening by the workpiece of sawing.
The utility model is because workpiece is made rotary cutting, and the cutting cross-sectional length changes minimum, makes the sawing machine running steadily, and cutting force changes little.Because the cutting overall process from axially being the tangent line processing of the circle that dwindles gradually, has improved the geometric accuracy in cutting cross section, reduced the cutting power drain again.This sawing machine cuts 1/2 diameter, round steel pipe cutting wall thickness to round steel and promptly finishes blanking, reduces empty cutter, improves work efficiency.Logical this workpiece rotation sawing can realize that saw band pursues the tooth stress equalization, and blade is stressed little, prolongs the service life of saw band.
The utility model is described in further detail below in conjunction with Figure of description, and provide embodiment.
Fig. 1 is the band sawing machine structural representation.
This sawing machine agent structure comprises sawing machine seat 1 and saw frame 5, and belt wheel 10 is set on the saw frame 5, is used for swelling and transmission saw band 9, and guiding trestle 11 is used for clamping, supports and reverses saw band 9.Workpiece rotating device is installed on the sawing machine seat 1, comprises motor 12, gearbox 3, and gearbox 3 is provided with gear change hand lever 4.Gearbox 3 is cooperated with bearing holder (housing, cover) 6 by gears engaged by its output; Also can pass through sprocket wheel, chain drive cooperation; Or cooperate by various ways such as frictional drive.Bearing bracket stand 2 is used for back shaft bearing sleeve 6 and joins with bearing holder (housing, cover) 6 work.Claw 7 more than two or two is set on the bearing holder (housing, cover) 6, and workpiece 8 is by bearing holder (housing, cover) 6 endoporus and fastening by claw 7.When sawing machine was worked, saw band 9 was with saw frame 5 downward cut workpiece 8, and motor 12 drives gearbox 3 and rotates with the bearing holder (housing, cover) 6 that is mated, and the workpiece 8 that are fastened in the bearing holder (housing, cover) 6 and then rotate, and realize two motion sawings of saw band, workpiece.The direction of rotation of workpiece is opposite with the sawing of saw band trend.
