Specific implementation process：According to the features of shape of workpiece 41, by workpiece 41 be placed on the different supporting rod 25 of angle or
On auxiliary rod 27, so that workpiece 41 can more be stablized.Can play to a certain extent prevents workpiece 41 from supporting rod
25 and auxiliary rod 27 drop to probability on ground, so as to play the role of workpiece 41 of conveniently taking.It is controlled by numerical control box 14
Cutter device 13 is processed workpiece 41, reduces the wear extent of supporting rod 25 and auxiliary rod 27 using Wear-resistant, high-temperature resistant coating,
And reduce the amount that supporting rod 25 and auxiliary rod 27 are worn by workpiece 41, enable workpiece 41 it is more stable be placed on supporting rod 25
On auxiliary rod 27, so as to reduce the probability that workpiece 41 drops from supporting rod 25 and auxiliary rod 27, workpiece of conveniently taking is played
41 effect.
Embodiment 2：A kind of gantry steel-plate cutter, as shown in Figures 4 and 5, can difference lies in frame 24 with embodiment 1
It is moved in braced frame 22.
22 upper end of braced frame is fixedly connected with the guide rail 31 parallel with rack 11, and 24 lower end of frame is equipped with and is rolled with guide rail 31
The guide wheel 32 of dynamic connection, promotes frame 24, is rolled by guide wheel 32 on guide rail 31, you can easily make frame 24 and supporting rod
25 move in braced frame 22.It, can be by frame 24 and support when there is workpiece 41 to be inadvertently fallen off from supporting rod 25 to ground
Bar 25 is removed, and then directly drops to ground without being taken with arm through supporting rod 25 from workpiece 41 of taking on the ground
Workpiece 41, so as to play the effect for workpiece 41 of conveniently taking.Guide rail 31 is located in braced frame 22, prevents from falling from supporting rod 25
Fall and accumulate the movement that waste material on the ground stops guide wheel 32, so that being rolled on guide rail 31 of can more smoothing out of guide wheel 32
It is dynamic, so as to play the role of being moved easily frame.Also the effect that guide wheel 32 is prevented to be rolled into the workpiece 41 on the ground that drops can be played
Fruit plays the role of protecting workpiece 41.
Frame 24 is fixedly connected with the protective cover 34 parallel with guide rail 31, and protective cover 34 is arranged on 31 top of guide rail.It utilizes
Protective cover 34 prevents the thermal-flame generated during the work time to be directly injected to guide rail 31, can also prevent from supporting rod 25 or auxiliary
The workpiece fallen down on bar 27 41 and waste material is helped to injure guide rail 31 by a crashing object, so as to play the role of improving 31 service life of guide rail.It protects
Shield 34 tilts down so that the waste material dropped on protective cover 34 can slide from protective cover 34, prevent protective cover 34 from accumulating
Excessive waste material is subject to crushing protective cover 34, improves 34 service life of protective cover.
As shown in Figure 4 and Figure 6, braced frame 22 is equipped with the fixing piece of locking frame 24, and 24 bottom of frame is equipped with mounting hole,
Braced frame 22 is fixedly connected with fixed plate 33, and fixing piece is the fixed pin for being threadedly coupled with fixed plate 33 and being clamped with mounting hole
35.When needing to cut workpiece 41, fixed pin 35 is rotated in fixed plate 33, fixed pin 35 is moved up, and is inserted into
In mounting hole, fixed pin 35 and mounting hole clamping, so that frame 24 is locked in braced frame 22 so that supporting rod 25 and auxiliary
It helps the workpiece 41 on bar 27 can be more stable, can reduce what workpiece 41 dropped from supporting rod 25 and auxiliary rod 27 to a certain extent
Probability, so as to play the role of workpiece 41 of conveniently taking, meanwhile, it prevents frame 24 from moving in process, can also play
Ensure the effect of machining accuracy.
35 upper end of fixed pin is equipped with taper surface 36, and mounting hole is set to the bellmouth 38 being bonded with taper surface 36.Processed
Cheng Zhong, the high temperature that cutter device 13 produces may be such that frame is heated and deforms.By taper surface 36, even if bellmouth
38 become smaller when heated, and taper surface 36 is also inserted into bellmouth 38, realizes the locking of frame 24, can so as to play raising
By the effect of property.35 lower end of fixed pin is fixedly connected with handle 37, and the work for facilitating and rotating fixed pin 35 can be played using handle 37
With achieving the effect that easy to use.
Specific implementation process：Frame 24 is promoted to enable workpiece 41 convenient to suitable position in braced frame 22
It is placed on supporting rod 25 and auxiliary rod 27, plays effect easy to use.Then frame 24 is promoted again, is moved to workpiece 41
13 lower section of cutter device.Swing handle 37 moves up fixed pin 35, so that taper surface 36 is inserted into bellmouth 38,
Frame 24 is locked in braced frame 22.Then using numerical control box 14 cutter device 13 is controlled to cut workpiece 41.If
Workpiece 41 is inadvertently fallen off from supporting rod 25 and auxiliary rod 27, can move down fixed pin 35, makes taper surface 36 and bellmouth 38
Then the status releasing of clamping promotes frame 24, people can directly take workpiece 41 from ground, so as to fulfill workpiece of conveniently taking
41 effect.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model be subject to Patent Law.
