By using above-mentioned technical proposal, connecting hole inner sidewall and gas-guide tube lateral wall are equipped with sealing ring one, guarantee connection Leakproofness between hole and gas-guide tube is equipped with sealing ring two between air entry inner sidewall and guiding tube lateral wall, guarantee suction hole Leakproofness between sucker, to guarantee that sucker stabilization adsorbs plate.

Further, the groove inner sidewall is fixed with protective plate close to workbench lateral wall one end.

By using above-mentioned technical proposal, by adding protective plate, corresponding part is hidden in inside workbench, people is prevented Member touches corresponding part, to play a protective role to it.

Further, the protective plate is rotationally connected with groove inner sidewall.

By using above-mentioned technical proposal, protective plate is rotatably connected on groove inner sidewall, in this way, protective plate can along its with it is recessed It is rotated at slot inner sidewall rotation connection, in this way, when corresponding part need to be repaired or replaced, without removing protective plate, with It is anti-lost.

Further, the protective plate is equipped with knob far from groove side.

By using above-mentioned technical proposal, staff can hold knob, rotate protective plate, facilitate the behaviour of staff Make.

In conclusion the utility model has the following beneficial effects:

1, plate is placed on the table, and sucker is connected to the bottom surface of plate, at this point, starting negative pressure pump, extracts sucker out Air between plate, makes sucker suction live plate, and having makes plate keep stable advantage in bending；

2, protective plate is rotatably connected on groove inner sidewall, in this way, protective plate can along its at groove inner sidewall rotation connection Rotation, in this way, when corresponding part need to be repaired or replaced, without removing protective plate, with anti-lost.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment:

A kind of bending machine tool, referring to Fig.1 comprising rack 1, knife rest 3 and workbench 2, the lateral wall of workbench 2 offer Groove 4；The inner sidewall of groove 4 is equipped with protective plate 9 close to 2 lateral wall one end of workbench, and protective plate 9 is connected to by pin rotation 4 inner sidewall of groove, protective plate 9 are fixedly connected with knob 91 by screw far from 4 side of groove, and staff can pull knob 91, rotate protective plate 9 at 4 rotation connection of groove along it, to facilitate the operation of staff.

Referring to Fig. 2 and Fig. 3, the bottom of groove 4 is equipped with column 5, and column 5 is far from 4 bottom end of groove by being welded and fixed It is connected with fixed plate 6；Support rod 61 is fixed with by screw in fixed plate 6,61 one end of support rod is fixedly connected by screw There is link block 62, runs through on link block 62 and be equipped with connecting hole 621,621 inner sidewall of connecting hole is connected with gas-guide tube 64, connecting hole Sealing ring 1 is equipped between 64 lateral wall of 621 inner sidewalls and gas-guide tube, to guarantee between connecting hole 621 and gas-guide tube 64 Leakproofness；Link block 62 is equipped with the suction hole 622 communicated with connecting hole 621, and 622 inner sidewall of suction hole is connected with sucker 63, Sucker 63 is equipped with the guiding tube 631 that can be inserted into suction hole 622, sets between 631 lateral wall of 622 inner sidewall of suction hole and guiding tube There is sealing ring 2 6221, to guarantee the leakproofness between suction hole 622 and sucker 63.

Referring to Figure 1 and Figure 3, the upper surface of workbench 2, which is run through to be equipped with, stretches out hole 21, stretches out at the top of hole 21 and groove 4 and communicates, Sucker 63, which is located at, to be stretched out in hole 21；The bottom of groove 4 is equipped with negative pressure pump 7, and supervisor 71, the supervisor 71 are connected on negative pressure pump 7 For flexible plastic pipe, supervisor 71 is connected far from 7 one end of negative pressure pump with gas-guide tube 64.

Referring to Fig. 4,4 bottom of groove is equipped with fixed block 8 by screw, and fixed block 8 is equipped with the sliding being inserted into for column 5 Hole 81,5 lateral wall of column are arranged with spring, and for spring as elastic component 51, spring one end is connected to 6 bottom surface of fixed plate, spring The other end is connected to 8 upper surface of fixed block, is acted on by the elastic force of spring, realizes moving up and down for column 5.

Referring to Fig. 4, the inner sidewall cementation of slip hole 81 is equipped with rubber layer 811, when column 5 moves up and down under the effect of elasticity When, column 5 applies resistance, prevent column 5 it is mobile it is too fast cause it is unstable；The bottom cementation of slip hole 81 is equipped with resilient cushion 812, when column 5 moves down under the effect of elasticity, abuts to 81 bottom of slip hole, play the role of damping.

Working principle is as follows:

When bending need to be carried out to plate, plate is placed on workbench 2, plate bottom surface is connected to sucker 63, this When, protective plate 9 is rotated, negative pressure pump 7 is started, so that air between sucker 63 and plate bottom surface is along gas-guide tube 64, using Supervisor 71 is extracted, so that sucker 63 be made to adsorb plate, realizes the fixation to plate.

At this point, knife rest 3 moves down, bending is carried out to plate, plate two sides are upturned, under spring force effect, Column 5 moves down, and drives sucker 63 to move down, so that sucker 63 be made to fall off from plate.

Column 5 is moving down, until abutting to sliding trench bottom, under spring force effect, column 5 is moved up, It and so on moves up and down, until stopping.In the process, rubber layer 811 effectively slows down the movement speed of column 5, reduces The frictional dissipation of column 5；812 column 5 of resilient cushion plays damping effect.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
