[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a bending machine for automobile plates, including a bending machine body 1, an upper pressure head 2 is movably installed on the top of the bending machine body 1, a front plate 20 is fixedly installed in front of the upper pressure head 2, a lower mold 3 is fixedly installed on the bottom of the bending machine body 1 below the upper pressure head 2, a main controller 4 is fixedly installed on one side of the bending machine body 1, and a foot controller 5 is also movably installed on the bending machine body 1 below the main controller 4, a supporting plate 6 is fixedly installed on the bending machine body 1 in front of the lower mold 3, a limit rod 7 is movably installed below the supporting plate 6, a protective rod 8 is arranged on the supporting plate 6, and the protective rod 8 is movably installed on the supporting plate 6 through a support rod 15.

[0021] like Figure 2-Figure 3As shown, the support plate 6 is an inverted L-shaped structure, and a plurality of support plates 9 are fixedly installed at the angle position in the support plate 6. A mounting groove 12 is provided in the support plate 9. The mounting groove 12 is provided in the support plate 9 to realize the installation of the limit rod 7 and ensure that the limit rod 7 can realize horizontal movement. A storage groove 10 is provided on the top of the support plate 6. By providing the storage groove 10, the protection rod 8 can be stored in the storage groove 10, so that when the plate is bent, the support plate 6 can support one end of the plate, and the plate located at the two ends can be supported. A socket 11 is provided on the top of the support plate 6 between the support plates 9. The setting of the socket 11 can provide conditions for the movable installation of the support rod 15. Connecting screws 13 are inserted and installed at both ends of the limit rod 7. One end of the connecting screw 13 is threadedly connected to the support plate 6. The connecting screw 13 between the support plate 6 and the limit rod 7 is sleeved with a first compression spring 14. A handle 21 is fixedly installed at the front end of the limit rod 7. Through the setting of the limit rod 7 that can be reset by itself, multiple support rods 15 can be limited synchronously;

[0022] like Figure 3-Figure 4 As shown, the upper end of the support rod 15 is fixedly connected to the slot 18, the lower end of the support rod 15 is fixedly installed with a limit block 16, the outer side of the support rod 15 is fixedly installed with a fixing ring 17, the support rod 15 located between the fixing ring 17 and the protective rod 8 is provided with a slot 18, the support rod 15 is inserted and installed in the corresponding socket 11, and the support rod 15 located between the bottom of the storage groove 10 and the fixing ring 17 is also provided with a second compression spring 19.

[0023] It should be noted that the utility model is a bending machine for automobile plates. When the lower mold 3 needs to be cleaned or maintained, the handle 21 can be pushed toward the bending machine body 1, so that the limit rod 7 moves backward in the installation groove 12 of the multiple support plates 9, and the two ends of the limit rod 7 are also moved on the corresponding connecting screws 13 respectively and the first compression spring 14 is compressed toward the bending machine body 1, so that the front end of the limit rod 7 is disengaged from the card slot 18 outside the multiple support rods 15, and then, with the help of the action force of the second compression spring 19, the second compression spring 19 lifts the fixing ring 17, so that The fixing ring 17 cooperates with the support rod 15 to lift the protection rod 8, so that the upper end of the limit block 16 located at the outer position of the support rod 15 abuts against the lower end of the horizontal part of the support plate 6. Then, the hand is separated from the handle 21, and the limit rod 7 can be moved forward in the installation groove 12 by the force of the two first compression springs 14 on the limit rod 7, and the limit rod 7 is placed at the lower ends of multiple limit blocks 16. Therefore, multiple support rods 15 can be supported and limited synchronously, so as to realize the rapid lifting and limiting of the protection rod 8, and then the protection rod limits the downward movement of the front plate 20 to protect the operator's hand;

[0024] When storing the protective rod 8, first use the hand force to push the handle 21 toward the direction of the bending machine body 1, and then move the limit rod 7 backward as mentioned above, and then press the protective rod 8 downward, so that the protective rod 8 drives the multiple support rods 15 to move downward in the corresponding sockets 11 and compress the second compression spring 19 to the bottom of the storage groove 10. When the protective rod 8 is stored in the storage groove 10, release the handle 21, and use the force of the first compression spring 14 to make the limit rod 7 move forward in the installation groove 12 and snap into the slot 18 on the outside of the multiple support rods 15, so as to limit the support rod 15.
