For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a bending and positioning device for automotive longitudinal beams, comprising:

[0033] The frame 1 is equipped with a bending and positioning mechanism. It should be noted that the bending and positioning mechanism is used to bend and position the longitudinal beam of the car to ensure the accuracy of bending.

[0034] The bending positioning mechanism includes a top frame 3, a rotating shaft 4, a sleeve 5, a torsion spring 6, a threaded cylinder 8, a limit plate 9, a hydraulic cylinder 10, a pressure plate 11, a cylinder 15, and a positioning rod 16.

[0035] The top of the top frame 3 is fixedly connected to the frame 1. The rotating shaft 4 is rotatably installed on the top frame 3. The sleeve 5 is fixedly sleeved on the outside of the rotating shaft 4. The torsion spring 6 is fixedly installed between the sleeve 5 and the top frame 3. The threaded cylinder 8 is fixedly connected to the limiting plate 9. It should be noted that the function of the limiting plate 9 is to limit the longitudinal beam of the car, that is, by blocking one side of the longitudinal beam of the car by the limiting plate 9, the longitudinal beam of the car is placed in the designated position.

[0036] The bottom of the hydraulic cylinder 10 is fixedly installed on the frame 1. The hydraulic rod of the hydraulic cylinder 10 is fixedly connected to the pressure plate 11. The cylinder 15 is fixedly installed on the rotating shaft 4. The positioning rod 16 is fixedly installed on the top of the pressure plate 11. The positioning rod 16 is engaged with the cylinder 15.

[0037] Using the aforementioned bending and positioning mechanism, the automotive longitudinal beam is placed on the automotive longitudinal beam placement seat 2, so that the left side of the automotive longitudinal beam contacts the limiting plate 9, thereby limiting the automotive longitudinal beam. Then, the hydraulic cylinder 10 is activated, causing the positioning rod 16 to move out of the cylinder 15. At this time, the torsion spring 6 resets and drives the rotating shaft 4 to rotate, which in turn causes the threaded cylinder 8 to drive the limiting plate 9 to rotate, thus separating the limiting plate 9 from the automotive longitudinal beam. This does not affect the subsequent bending work of the automotive longitudinal beam, until the pressure plate 11 presses and positions the automotive longitudinal beam.

[0038] Specifically, the bending positioning mechanism also includes a lead screw 7 and a slide rod 13. The lead screw 7 is rotatably mounted on the rotating shaft 4 and is threadedly connected to the threaded cylinder 8. The slide rod 13 is fixedly mounted on the threaded cylinder 8. Two sliding grooves are opened at the end of the rotating shaft 4, and the slide rod 13 is slidably mounted in the sliding grooves.

[0039] By rotating the lead screw 7, the threaded cylinder 8 can drive the limiting plate 9 to move laterally. This allows the position of the limiting plate 9 to be adjusted to meet the positioning and bending requirements of automotive longitudinal beams of different sizes.

[0040] Specifically, the bending positioning mechanism also includes a car longitudinal beam placement seat 2. The bottom of the car longitudinal beam placement seat 2 is fixedly connected to the frame 1. Two movable holes are opened on the top of the car longitudinal beam placement seat 2, and the pressure plate 11 is vertically slidably installed in the two movable holes.

[0041] The above-mentioned bending and positioning mechanism is used to place the automobile longitudinal beam on the automobile longitudinal beam placement seat 2. The setting of the moving hole allows the pressure plate 11 to move stably in the vertical direction.

[0042] Specifically, the bending positioning mechanism also includes a second hydraulic cylinder 17 and a bending plate 18. The second hydraulic cylinder 17 is fixedly installed on the top frame 3, and the hydraulic rod of the second hydraulic cylinder 17 is fixedly connected to the bending plate 18.

[0043] After the automotive longitudinal beam is positioned using the aforementioned bending and positioning mechanism, hydraulic cylinder 17 is activated, causing the bending plate 18 to move downwards and bend the positioned automotive longitudinal beam.

[0044] Specifically, a rubber pad 12 is fixedly installed at the bottom of the pressure plate 11. It should be noted that this can protect the pressing part.

[0045] Specifically, the top frame 3 has a vertical hole, and the positioning rod 16 contacts the inner wall of the vertical hole. It should be noted that this facilitates the vertical movement of the positioning rod 16.

[0046] Specifically, a stop bar 14 is fixedly installed on the frame 1. The stop bar 14 is located in front of the limit plate 9. It should be noted that the limit plate 9 can be blocked and limited.

[0047] Specifically, a knob is fixedly installed at the end of the lead screw 7. It should be noted that the lead screw 7 is rotated by the knob.

[0048] Working principle:

[0049] S1: Place the car longitudinal beam on the car longitudinal beam placement seat 2 so that the left side of the car longitudinal beam contacts the limiting plate 9 to limit the car longitudinal beam. Then start the hydraulic cylinder 10 to move the pressure plate 11 down. The pressure plate 11 drives the positioning rod 16 down, so that the positioning rod 16 moves out of the cylinder 15. At this time, the torsion spring 6 resets and drives the rotating shaft 4 to rotate, which in turn allows the threaded cylinder 8 to drive the limiting plate 9 to rotate, so that the limiting plate 9 separates from the car longitudinal beam. This does not affect the subsequent bending work of the car longitudinal beam until the pressure plate 11 presses and positions the car longitudinal beam.

[0050] S2: The stop bar 14 can block and limit the limit plate 9. The limit plate 9 can be rotated to move it to the initial position and then locked into the cylinder 15 by the positioning rod 16 to limit it.

[0051] S3: Rotating the lead screw 7 allows the threaded cylinder 8 to move the limiting plate 9 laterally, thus adjusting the position of the limiting plate 9 to meet the positioning and bending requirements of automotive longitudinal beams of different sizes.

[0052] S4: Start hydraulic cylinder 17 to move bending plate 18 down and bend the positioned automotive longitudinal beam.

[0053] The present invention provides a detailed description of an automotive longitudinal beam bending and positioning device. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
