Technical Field
The present invention relates to worktables for metal band sawing machines, in particular to a worktable having high sawing speed and high precision for a sawing machine.
Background Art
At present, the worktables of sawing machines are mainly categorized into single rear worktables and central sawing worktables. A single rear worktable is arranged behind the saw blade, and the saw-off parts are in an unfixed state; consequently, the sawing teeth of the saw blade may be damaged or broken easily; a central sawing worktable has a single jaw opening, and the saw blade carries out the sawing from the center of the jaw opening; since the worktable has a single jaw opening and the workpiece is not in an ideal state, it is impossible to clamp and fix the workpiece and the saw-off parts at the same time; consequently, the sawing teeth of the saw blade may be damaged or broken easily. All of the worktables described above can't avoid the huge impact of the saw-off parts on the saw blade when the sawing is finished.

Hereunder some preferred embodiments of the present invention will be detailed with reference to the accompanying drawings, in order to enable those skilled in the art to understand the advantages and features of the present invention more easily and define the scope of protection of the present invention more clearly.
As shown in Figs. 1-4, the present invention discloses a high-speed and high-precision worktable for a sawing machine, which comprises a worktable 11, wherein a front clamping device and a rear clamping device are provided on the worktable 11 respectively and operate independently to clamp a workpiece at the same time. The sawing operation is stable and reliable, at high sawing speed and high accuracy. There is no impact on the saw blade when the sawing is finished since the workpiece and the saw-off parts are in a clamped and fixed state; thus the service life of the saw blade is prolonged effectively.
The front clamping device comprises two front micro oil cylinders 8, a first fixed vice 7 and a second fixed vice 9, wherein the two front micro oil cylinders 8 are fixedly connected with the first fixed vice 7 and the second fixed vice 9 respectively and fixed on the worktable 11, and the two front micro oil cylinders 8 can drive the first fixed vice 7 and the second fixed vice 9 to act respectively; the rear clamping device comprises a clamping oil cylinder 13 and a movable vice 12, wherein the clamping oil cylinder 13 is fixedly connected to the worktable 11 through the movable vice 12, and a channel is provided between the movable vice 12 and the worktable 11, thus the movable vice 12 can be moved with respect to the worktable 11; of course, the specific quantities of oil cylinders and vices related to the front clamping device and the rear clamping device may be increased or decreased according to the size of the worktable.
A vice guide rod 14 is fixedly connected to a jaw plate 3 through a self-lubricating bearing 2 and a clamping oil cylinder fixing plate 1 sequentially, and a clamping oil cylinder flange 6 is connected to the jaw plate 3 through threads; the clamping oil cylinder fixing plate 1 is fixed on the worktable 11.
The worktable supporting plate 4 is fixedly connected with the worktable 11, and is used to receive workpieces. The two sides of the worktable supporting plate 4 are fitted with a first worktable hold-down bar 5 and a second worktable hold-down bar respectively.
The first fixed vice 7 and the second fixed vice 9 are provided with a top hold-down device respectively, which is mainly used to prevent the broken pieces of saw blades used in bundle from flying out and injuring the workers, and prevent any broken piece of saw blades from flying out and injuring the workers during high-speed sawing. Thus the worktable has a high safety factor.
The top hold-down device comprises a first top hold-down oil cylinder fixing plate 15, two top hold-down screw rods 16, two top hold-down oil cylinders 17, two top hold-down blocks 18, two top hold-down guide rods 19, and a second top hold-down oil cylinder fixing plate 20, wherein the top hold-down guide rods 19 pass through the first top hold-down oil cylinder fixing plate 15 and can move up and down; the first top hold-down oil cylinder fixing plate 15 and the second top hold-down oil cylinder fixing plate 20 are fitted with the corresponding top hold-down screw rods 16 respectively; the top hold-down oil cylinders 17, the top hold-down blocks 18, the top hold-down guide rods 19, and the two top hold-down screw rods 16 are fixedly connected with the corresponding first fixed vice 7 and second fixed vice 9 respectively.
Working principle and function: after a workpiece is placed on the worktable supporting plate 4, the two front micro oil cylinders can drive the first fixed vice 7 and the second fixed vice 9 to act to clamp the workpiece respectively; at the same time, the clamping oil cylinder 13 drives the movable vice 12 to clamp the workpiece; in that way, the front clamping device and the rear clamping device work together, and both the workpiece and the saw-off parts are in a fixed state, thus the sawing teeth of the saw blade will not be damaged or broken easily.
In the case that saw blades are used in bundle or the sawing operation is carried out at a high speed, the top hold-down devices can be moved down by means of the corresponding top hold-down guide rods 19 respectively, and the corresponding top hold-down blocks 18 hold down the saw blades, so as to prevent any broken piece of the saw blades in bundle from flying out and injuring the workers, and prevent the broken pieces of saw blades from flying out and injuring the workers during high-speed sawing. Thus the worktable has a high safety factor.
