Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The high-efficiency plate shearing device as shown in the attached figures 1 to 3 comprises a workbench 2 which is arranged on a plate shearing machine body and used for placing plates. The basic working structure of the shearing machine body is the prior art, a material pressing frame 2 for pressing plates and a shearing tool 1 for shearing the plates are arranged on a workbench 2, and the material pressing frame 2 and the shearing tool 1 are driven to lift by different driving mechanisms respectively.
Be provided with protection machanism on the workstation 2, protection machanism is including the forced induction ware 3 of response staff and the stopper 4 that offsets with workstation 2, forced induction ware 3 inductive probe 9 with stopper 4 is all fixed to be set up on guard plate 5, guard plate 5 vertical motion under lifting unit's drive, the lower extreme of stopper 4 is less than inductive probe 9's lower extreme. The pressure sensor 3 is in signal connection with a controller, and the controller is in signal connection with a power supply cut-off device of the plate shearing machine body.
Before the shearing tool 1 moves downwards to cut, the lifting assembly drives the protection plate 5 to move downwards, if the sensing probe 9 senses a hand of a person, the pressure sensor 3 transmits a signal to the controller, and the controller cuts off a power supply of the plate shearing machine through the power supply cutter, so that the shearing tool 1 is prevented from damaging the hand of the person. If the hand is not in the dangerous area, the limiting block 4 is abutted to the workbench 2, and the induction probe 9 is prevented from being abutted to the workbench 2 to generate a pressure signal.
The lifting component is a material pressing frame 7 which is arranged on the plate shearing machine body and used for pressing plates, the material pressing frame 7 moves vertically under the driving of a hydraulic cylinder, the protection plate 5 moves vertically along with the material pressing frame 7, the whole structure is more simplified and reasonable, and due to the arrangement of the spring part 6, when the limiting block 4 is abutted to the workbench 2, the material pressing frame 7 can continue to move downwards to press the plates to be sheared.
As shown in fig. 3, when the spring element 6 is in a natural state, the lower end of the material pressing frame 7 is higher than the lower end of the induction probe 9. In the process of moving the material pressing frame 7 downwards, the hand of a person can be detected by the induction probe 9 so as to prevent the hand of the person from being pressed by the material pressing frame 7.
The lower end of the induction probe 9 is provided with a hand induction rod 8, the hand induction rod 8 is transversely arranged, the length direction of the hand induction rod 8 is the same as that of the workbench 2, and hands can be better detected through the hand induction rod 8. The lower extreme of people's hand response pole 8 is higher than the lower extreme of stopper 4, when stopper 4 and workstation 2 looks butt, leave the clearance between people's hand response pole 8 and the workstation 2 to avoid pressure sensor 3 to detect pressure.
The lower extreme of stopper 4 is provided with the rubber cushion, reduces the impact to workstation 2 when stopper 4 moves down.
The working principle of the utility model is as follows: the plate to be cut is placed on the workbench 2, the material pressing frame 7 is driven by the hydraulic mechanism to move downwards, the protection plate 5 is driven by the material pressing frame 7 to move downwards, in the process that the protection plate 5 moves downwards, if the hand of a worker is located in a dangerous area below the protection plate 5, the hand induction rod 8 can press the hand of the worker, so that the pressure sensor 3 receives a pressure signal, then the pressure sensor 3 sends a signal to the controller, the controller cuts off the power supply of the plate shearing machine, and the situation that the material pressing frame 2 and the cutting tool 1 continuously move downwards to cause injury to the hand of the worker is avoided; if the hands of the worker are not in the dangerous area below the protection plate 5, the protection plate 5 moves downwards until the limiting block 4 abuts against the workbench 2 and compresses the spring part 6, the pressure sensor 3 cannot receive a pressure signal in the process, the shearing machine works normally, the material pressing frame 2 continues to move downwards and presses the plate, and then the shearing tool 1 moves downwards to shear the plate.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
