Description

Technical Field

[0001] The invention relates to the technical field of punching assistance, and in particular to a punching assistance device. Background Art

[0002] Punching of hardware parts usually uses a punching machine to perform the punching operation of the workpiece. When the punching machine is used for punching operation, personnel should avoid being too close to the punching end of the punching machine. During the punching process, once the workpiece splashes or the mold explodes, the workpiece fragments or mold fragments flying around have a strong impact force. Once personnel are too close, the flying fragments can easily cause impact injuries to personnel, leading to safety accidents. However, when the existing punching machine is used for punching, it is impossible to limit the safe standing position of the staff, and it is also impossible to prevent other personnel from approaching the punching machine, which has defects.

[0044] The specific usage and function of this embodiment are as follows:

[0045] When punching the hardware, the workpiece is limited and fixed at the punching end of the punching machine 1, and then the switch button for controlling the punching of the punching machine 1 is pressed to realize the punching of the workpiece;

[0046] In order to ensure that the present invention avoids safety accidents when punching the workpiece, the position of the staff controlling the punching of the workpiece is limited, and the surrounding personnel are monitored to see if there are any people near the punching machine 1. The specific operation is as follows:

[0047] Staff station restrictions:

[0048] After the worker fixes the workpiece limit at the punching end of the punching machine 1, when the worker needs to press the switch button for controlling the punching of the punching machine 1, because the switch button is stored in the switch storage groove 106, the worker needs to move to the front of the front end of the punching machine 1 and stand on the pressure plate 203. At this time, under the pressure of the worker's own weight, the pressure plate 203 will slide down along the pressure groove 2015, and it will press the rubber support block 208, and the rubber support block 208 will be compressed and deformed. When the pressure plate 203 is stepped on, the button end of the electromagnetic on-off switch a205 is pressed, and the electromagnetic on-off switch a205 is in a pressed start state. The electromagnetic on-off switch a205 gives a feedback signal to the microcontroller 2016, and the microcontroller 2016 controls the electromagnetic adsorption member a5 to be powered on and started. The electromagnetic adsorption member a5 will magnetically attract the iron block 6, and the iron block 6 will slide to the right along the embedded groove 103 through the roller 602 until the right end surface of the iron block 6 is magnetically in contact with the electromagnetic adsorption member a5. At this time, the pressure plate 203 is pressed on the button end of the electromagnetic on-off switch a205, and the electromagnetic on-off switch a205 is in a pressed start state. The electromagnetic on-off switch a205 gives a feedback signal to the microcontroller 2016, and the microcontroller 2016 controls the electromagnetic adsorption member a5 to be powered on and started. The electromagnetic adsorption member a5 will magnetically attract the iron block 6, and the iron block 6 will slide to the right along the embedded groove 103 through the roller 602 until the right end surface of the iron block 6 is magnetically in contact with the electromagnetic adsorption member a5. The mating opening b601 corresponds to the switch storage slot 106 and the press-fit opening a303. At this time, the staff can press the switch button by pressing the mating opening a303 and the press-fit opening b601 to realize the punching operation; and when the staff leaves the pressing plate 203, under the reset rebound of the reset spring b2014, the pressing plate 203 will no longer press the button end of the electromagnetic opening and closing switch a205. At this time, the electromagnetic adsorption part a5 will be powered off and closed, and there will be no electromagnetic adsorption. Under the magnetic attraction of the attachment a5, the reset spring c604 will reset and rebound, so that the iron block 6 slides to the left along the embedded groove 103 through the roller 602, and moves again to the state where the left end face of the iron block 6 contacts the electromagnetic adsorption component b4. At this time, the press-fit opening b601 is offset from the switch storage groove 106 and the press-fit opening a303, so the staff will not be able to press the switch button to perform the punching operation. Therefore, through this design of the present invention, the staff can realize the position limitation;

[0049] Monitor whether there are people approaching:

[0050] When people approach the punching machine 1, except for the safe area in front of the front end of the punching machine 1, when people approach the punching machine 1 from other areas, they will inevitably stand on the concave pressure plate 202, and under the pressure of the person's own weight, the concave pressure plate 202 will slide down along the concave pressure groove 204, and the concave pressure plate 202 will press against the concave rubber support block 206, and the concave rubber support block 206 will be compressed and deformed. At this time, the concave pressure plate 202 will also press against the button end of the electromagnetic opening and closing switch b2011, and the electromagnetic opening and closing switch b2011 is in a pressed and started state. The electromagnetic opening and closing switch b2011 will give a feedback signal to the microcontroller 2016, and the microcontroller 2016 will control the electromagnetic adsorption component b4 to be energized. Start, because the magnetic force of the electromagnetic adsorption component b4 of the present invention is greater than the magnetic force of the electromagnetic adsorption component a5, when a person stands on the concave pressure plate 202, even if the staff stands on the stepping plate 203 at this time, the electromagnetic adsorption component b4 and the electromagnetic adsorption component a5 are both in the power-on start-up state, at this time, under the magnetic attraction of the electromagnetic adsorption component b4, the iron stopper 6 will be in magnetic contact with the electromagnetic adsorption component b4, and the press-fit opening b601 will also be offset from the switch storage groove 106 and the press-fit opening a303, so the staff will not be able to press the switch button to perform the punching operation. Therefore, when it is monitored and determined that a person approaches the punching machine 1 from other areas, the punching operation cannot be performed to avoid the occurrence of safety accidents.

[0051] Embodiment 2: A punching auxiliary device is provided based on the first embodiment, and the punching auxiliary device also includes: a square protective frame plate 101 is fixedly installed on the top surface of the punching machine 1 body adjacent to the front edge, and a tempered glass 102 is fixedly installed in the inner frame area of ​​the square protective frame plate 101.
