One end of the upper surface of the lower layer plate is convexly provided with a lower blocking edge perpendicular to the side edge, and the lower surface of the upper layer plate is convexly provided with an upper blocking edge which is in limit fit with the lower blocking edge.

The frame is convexly provided with a limiting surrounding edge which surrounds the periphery of the working table plate after the working table plate descends.

And a supporting edge which is matched with the lower surface of the working table plate in a supporting way after the working table plate descends is arranged on the rack.

The lifting mechanism is a hydraulic cylinder group, the cylinder body of each hydraulic cylinder is fixed on the frame, and the piston rod of each hydraulic cylinder is fixed with the lower surface of the working table plate.

The utility model discloses a work platen passes through hydraulic pressure elevating system and sets up in the frame to the work platen includes upper plate and lower plywood, lay axis of rotation and draw runner vertically roller on the lower plywood, the lower surface and each roller roll cooperation of upper plate, the steel sheet that the cutting is good can be placed on the upper plate, because upper plate and lower plywood can convenient relative movement, can be convenient push away from upper plate and steel sheet together, be in the part of workstation top when avoiding the operation, take away the steel sheet away that just can be convenient.

Detailed Description

In fig. 1, 2, 3 and 4, a frame 1 is provided with a work table 2 by lifting a hydraulic cylinder group, a cylinder body of each hydraulic cylinder 3 is fixed on the frame 1, and a piston rod of each hydraulic cylinder 3 is fixed to the lower surface of the work table 2. The working table plate 2 is provided with an upper plate 4 and a lower plate 5, sliding strips 6 are convexly arranged on two sides of the lower surface of the upper plate 4, the two sliding strips 6 are arranged in parallel with the side edges of the upper plate 4, guide sliding chutes 7 which are respectively in one-to-one corresponding sliding fit with the two sliding strips are formed in the upper surface of the lower plate 5, rollers 8 are arranged between the outer side groove walls of the two guide sliding chutes 7 and the corresponding side walls of the sliding strips 6, the rollers 8 are arranged on the side walls of the guide sliding chutes 7 through roller frames, the roller frames are strip-shaped bodies and are fixed on the groove walls of the guide sliding chutes 7, the rollers 8 are rotatably assembled on the roller frames, the rollers 8 are spherical rollers, and the sliding strips 6 are in rolling fit with the rollers 8, so that the guide between the upper plate and the lower plate is realized, and the common structure form for reducing friction is not detailed here. And the roller shafts 10 with the rotating axes vertical to the sliding strips 6 are distributed below the upper plate 4, the lower surface of the upper plate 4 is in rolling fit with the roller shafts 10, and two ends of each roller shaft 10 are rotatably assembled on the mounting strips 9 convexly arranged on the upper surface of the lower plate 5. Therefore, the upper plate can easily slide relative to the lower plate.

A lower retaining edge 11 is convexly arranged at one end of the upper surface of the lower layer plate 5, the lower retaining edge 11 is perpendicular to the side edge of the lower layer plate 5, and an upper retaining edge 12 which is in limit fit with the lower retaining edge 11 is convexly arranged on the lower surface of the upper layer plate 4, so that the upper layer plate can only slide in one direction relative to the lower layer plate.

A limiting surrounding edge 13 which surrounds the periphery of the working table plate 2 after the working table plate 2 descends is convexly arranged on the frame 1.

The frame 1 is also provided with a supporting edge 14 which is matched with the periphery of the lower surface of the working bedplate 2 after the working bedplate 2 descends, so that the support of a hydraulic cylinder group is not needed after the working bedplate 2 descends, the energy is saved, the supporting edge is stable in support, and the operation of the working bedplate can be reliably ensured.

When the cutting device is used, the working table plate is in a descending state and supported on the supporting edge, after the cutting operation is completed, the working table plate ascends under the action of the hydraulic cylinder group to be separated from the limitation of the limiting surrounding edge, then the upper plate is pushed to take the cut steel plate away from the cutting tool and the accessory structure thereof, the cut steel plate can be taken away by bypassing the limitation of the upper plate, therefore, the position of the cutting tool does not need to be adjusted every time when the same-size steel plate is cut, the working time is saved, and the cutting efficiency is improved.
