Description
Technical field
The present invention relates to a kind of band sawing machine equipment, particularly a kind of horizontal metal band sawing machine that is used for sawing ultra-large type hollow circuit cylinder workpiece.
Background technology
At present, general horizontal metal band sawing machine includes lathe bed, is installed in column and saw frame on the lathe bed, is provided with saw wheel and saw band in the saw frame, and saw frame and column flexibly connect, and can be, and be installed on the lathe bed and be positioned at the clamp of saw frame cutting mouthful below along the column oscilaltion.During work, workpiece is clamped by clamp, and saw frame descends to workpiece do cut-out processing then.But, when adopting the hollow circuit cylinder workpiece of general horizontal metal band sawing machine sawing ultra-large type (more than the diameter 3M), have following problem:
1. because the ultra-large workpiece diameter is big, the saw frame on the sawing machine of processing is wanted corresponding amplification, particularly will increase with the corresponding saw frame throat depth of workpiece, thereby make the lathe volume increase greatly.
2. when working owing to the horizontal metal band sawing machine of prior art, its workpiece all is to be fixedly clamped by clamp, and workpiece is only cut off processing up and down, and when sawing hollow circuit cylinder workpiece, its operating efficiency is lower.
Summary of the invention
The present invention provides a kind of horizontal metal band sawing machine of suitable sawing ultra-large type hollow circuit cylinder workpiece for solving the problem that above-mentioned general horizontal metal band sawing machine exists, and makes that the saw frame throat depth is less, operating efficiency is higher.
Technical scheme of the present invention is:
A kind of horizontal metal band sawing machine comprise lathe bed, be installed in the column on the lathe bed and be provided with the saw frame of saw wheel, saw band and guide head, but saw frame is characterized in that along the column oscilaltion: lathe bed is provided with and can supports and drive the V-arrangement workseat that workpiece rotates; Establish a drive roll and passive cylinder respectively above two about this V-arrangement workseat, and drive roll is in transmission connection by chain and reductor and the motor that is installed on the lathe bed; Two foreign sides are respectively equipped with a clamping cylinder about described V-arrangement workseat, the bottom of two clamping cylinders is articulated on the lathe bed respectively, two clamping cylinder push rods are a hinged pressing plate respectively, pressing plate lower end and fixedly vertical rod is hinged, pressing plate is provided with row's roller on one side, can compress turning of work piece at clamping cylinder effect lower platen by roller.
Among the present invention, its drive roll is made up of the barrel that a sprocket wheel and two ends are extended with rotating shaft; Passive cylinder is made of the barrel that two ends are extended with rotating shaft.It is simple in structure, reliable transmission.
Among the present invention, described fixedly vertical rod can be located at about the V-arrangement workseat on the outside.It is easy to connect.
Operation principle of the present invention is: behind the last loop section of the sawing hollow circuit cylinder workpiece that earlier saw frame descended, drive roll on the V-arrangement workseat is driven through reductor by motor and rotates, and drives workpiece and the equidirectional rotation of saw wheel that places on V-arrangement workseat drive roll and the passive cylinder simultaneously.Under the effect of clamping cylinder, two pressing plates will be pressed to workpiece in opposite directions, and by the roller contact and the workpiece pressing that approach most workpiece, the roller on the pressing plate rotates with turning of work piece, and the saw band of running is progressively carried out sawing to other annular section of turning of work piece.Like this, the saw frame throat depth among the present invention can reduce much than general horizontal metal band sawing machine; And the sawing time also can correspondingly reduce.
Therefore, the present invention has that the saw frame throat depth is less, operating efficiency is than advantages such as height.
Description of drawings
Fig. 1 is the structural representation of invention;
Fig. 2 is for being installed in the drive roll enlarged diagram on the V-arrangement workseat among Fig. 1;
Fig. 3 is for being installed in the passive cylinder enlarged diagram on the V-arrangement workseat among Fig. 1.
The specific embodiment
Among Fig. 1-3,1-saw frame, 2-saw wheel, 3-guide head, 4-saw band, 5-column, 6-pressing plate, 7-roller, 8-clamping cylinder, 9-lathe bed, 10-V shape workseat, the passive cylinder of 11-, 12-chain, 13-reductor, 14-motor, 15-drive roll, fixedly vertical rod of 16-, 17-workpiece, 18-rotating shaft, 19-barrel, 20-sprocket wheel.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of horizontal metal band sawing machine, comprise lathe bed 9, be installed in the column 5 on the lathe bed 9 and be provided with the saw frame 1 of saw wheel 2, saw band 4 and guide head 3, but saw frame 1 is fixed with supporting and drives the V-arrangement workseat 10 that workpiece rotates along column 5 oscilaltions on the lathe bed 9; This establishes a drive roll 15 and passive cylinder 11 respectively above V-arrangement workseat about 10 two, and drive roll 15 is in transmission connection by chain 12 and reductor and the motor 14 that is installed on the lathe bed; Described V-arrangement workseat about 10 two foreign sides are respectively equipped with a clamping cylinder 8, the bottom of two clamping cylinders 8 is articulated in respectively on the lathe bed 9, two clamping cylinder push rods are a hinged pressing plate 6 respectively, pressing plate 6 lower ends and fixedly vertical rod 16 is hinged, pressing plate 6 is provided with row's roller 7 on one side, can compress turning of work piece 17 at clamping cylinder 8 effect lower platens 6 by roller 7.
Described drive roll 15 is made up of the barrel 19 that a sprocket wheel 20 and two ends are extended with rotating shaft 18; Passive cylinder 11 is made of the barrel 19 that two ends are extended with rotating shaft 18.It is simple in structure, reliable transmission.
Described two fixedly vertical rod be separately fixed at V-arrangement workseat 10 about the outside on.It is easy to connect.
When the present invention works, first last loop section with saw frame 1 decline sawing hollow circuit cylinder workpiece 2, then, and starter motor 14, the drive roll 15 on the V-arrangement workseat 10 is in transmission connection with motor 14 by reductor 13, chain 12 and sprocket wheel 20, and is driven by motor 14.Drive roll 15 on the V-arrangement workseat 10 drives the workpiece 17 and saw wheel 2 equidirectional rotations that places on V-arrangement workseat drive roll 15 and the passive cylinder 11.Under the effect of clamping cylinder 8, two pressing plates 6 will be pressed to workpiece 17 in opposite directions, and by the roller contact and the workpiece pressing 17 that approach most workpiece, the roller on the pressing plate rotates with turning of work piece, thereby makes 4 pairs of other annular sections of turning of work piece of saw band of running progressively carry out sawing.Because its annular entity of hollow circuit cylinder workpiece can make the saw frame throat depth just can finish this workpiece of sawing less than workpiece radius by sawing in rotation, reduce much than general sawing machine saw frame throat depth, and the sawing time shortens.Be particularly suitable for major diameter flange and other large-scale hollow work-piece that the sawing wind power plant is used.
In addition, when the present invention installed and used, its bed piece can be installed under the ground level, can make work-handling convenient like this.
