DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-6 This application is described in further detail.

[0021] The present application embodiment discloses a personal safety protection mechanism for a bending machine. Figure 1-2 , including a bending machine body 1, a slide groove 2 is opened on both sides of one end of the bending machine body 1, a protective component 3 is connected to one end of the bending machine body 1, a lifting component 4 is connected to one end of the bending machine body 1, the lifting component 4 drives the bending plate 5 to move up and down to bend the parts, the lower end of the lifting component 4 is connected to the bending plate 5, one end of the bending machine body 1 is connected to a placement seat 6, the upper end of the placement seat 6 is opened with a clamping groove 7, the lower end of the protective plate 33 is located inside the clamping groove 7, so that the protective plate 33 is clamped with the placement seat 6, the protective component 3 includes a moving block 31 slidably installed on one side of the inside of the slide groove 2, one end of the moving block 31 is penetrated and connected with a round rod 32, and both ends of the round rod 32 are connected to both sides of the inner wall of the slide groove 2.

[0022] Reference Figure 3-6 , one end of the moving block 31 is connected to a protective plate 33, which protects the bending plate 5 during the bending process and plays a blocking role. If a part breaks during the bending process, the protective plate 33 performs blocking protection. The lower end of the protective plate 33 is located inside the clamping groove 7, and one side of the lower part of the protective plate 33 is connected to a support rod 34, one end of the support rod 34 is connected to a protective rod 35, and one end of the support rod 34 extends through and extends to the inside of the protective rod 35 and is connected to a pressure plate 36, one side of the inside of the protective rod 35 is connected to an air cushion 37, and one side of the outside of the protective rod 35 is connected to an elastic strip 38, and one end of the elastic strip 38 is connected to a rubber plate 39. The rubber plate 39 and the elastic strip 38 absorb the impact force generated by the collision of the broken parts to prevent the parts from directly contacting the protective plate 33. A slide plate 310 is connected to one side of the block 31, and a pull rod 311 is connected to one end of the slide plate 310. One end of the pull rod 311 extends through and extends to the outside of the protective plate 33. A spring 312 is sleeved on the outside of the pull rod 311. The spring 312 applies pressure to the slide plate 310, so that the fixed block 313 is plugged into the inside of the fixed groove 314, thereby fixing the protective plate 33 when not in use. One end of the spring 312 is connected to one side of the slide plate 310, and the other end of the spring 312 is connected to one side of the inner wall of the moving block 31. A fixed block 313 is connected to one end of the slide plate 310, and the fixed block 313 extends through and extends to the inside of the round rod 32. A fixed groove 314 is provided at the point where the round rod 32 corresponds to the penetration of the fixed block 313, and the fixed block 313 is located inside the fixed groove 314.

[0023] The implementation principle of a personal safety protection mechanism for a bending machine in the embodiment of the present application is as follows: when in use, in the initial state, the fixed block 313 is located inside the fixed groove 314, and the protective plate 33 is fixed at the upper part of the bending machine body 1. When the part needs to be bent, the part is placed inside the bending machine body 1, and the pull rod 311 is pulled to one side. The pull rod 311 drives the slide plate 310, and the slide plate 310 drives the fixed block 313 to move, so that the fixed block 313 moves to the outside of the fixed groove 314. At this time, the moving block 31 is no longer fixedly connected to the round rod 32, and the protective plate 33 falls downward into the inside of the clamping groove 7 under the action of gravity. , and then the protective plate 33 protects the opening of the bending machine body 1. When the bending plate 5 breaks during the processing of parts, the parts will not fly around under the protection of the protective plate 33, ensuring the safety of the staff. At the same time, the broken parts contact the rubber plate 39. Under the energy absorption of the rubber plate 39 and the elastic strip 38, the impact force of the parts is reduced. At the same time, the protective rod 35 moves to the side of the support rod 34, and the air cushion 37 contacts the pressure plate 36. Under the buffering of the air cushion 37, the impact force of the parts is further reduced, avoiding contact between the parts and the protective plate 33, damaging the protective plate 33, and extending the service life of the protective plate 33.
