Description

Technical Field

[0001] This utility model relates to the field of steel cross and longitudinal beam pressing technology, and in particular to a hot-forming steel cross and longitudinal beam pressing equipment with a composite bending mold structure. Background Technology

[0002] The hot-formed steel cross and longitudinal beam pressing equipment with composite bending die structure is a precision machining equipment for hot-formed high-strength steel, mainly used for pressing and forming automotive body structural parts (such as cross and longitudinal beams, A-pillars, sill beams, etc.).

[0003] Currently, single-sided drive is commonly used for limiting mechanisms of hot-formed steel horizontal and vertical beams. Single-sided drive requires only a single power source (such as an electric actuator or cylinder) and a small number of transmission components, simplifying the mechanical structure design and reducing the difficulty of processing and assembly. Single-sided drive occupies little space, making it particularly suitable for scenarios where equipment installation space is limited, saving lateral installation space.

[0004] Although the single-sided drive structure is simple, it is usually only equipped with a single guide rail or a single slider, which is difficult to resist the lateral force during the pressing process. The limit plate is prone to shaking, resulting in poor positioning repeatability. After long-term use, the single-sided guide component wears faster due to the concentrated force, which further aggravates the positioning deviation. Frequent calibration or replacement of components is required, increasing maintenance costs. To solve the above problems, a hot-formed steel cross and longitudinal beam pressing equipment with a composite bending die structure is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hot-forming steel cross and longitudinal beam pressing device with a composite bending mold structure, which aims to improve the problem of ineffective stable positioning in the prior art.

[0023] This utility model has the following beneficial effects:

[0024] 1.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 5 and Figure 6 The present invention provides an embodiment of a hot-formed steel cross and longitudinal beam pressing device with a composite bending mold structure, including a shell 1, a lifting pressing component provided on the inner side of the shell 1, limit components provided on both sides of the shell 1, a baffle 2 fixedly connected to the side of the shell 1, and a conveying component provided on the inner side of the baffle 2.

[0036] The limiting assembly includes a connecting plate 18, which is fixedly connected to the inner side of the outer shell 1. A housing 16 is fixedly connected to the side of the connecting plate 18. An electric push rod 17 is disposed inside the housing 16 and is fixedly connected to the side of the connecting plate 18. A limiting plate 9 is fixedly connected to the other end of the electric push rod 17. The electric push rod 17 serves as a power source, fixed to the side of the connecting plate 18, and its extension and retraction directly drive the lateral movement of the limiting plate 9. When the electric push rod 17 extends, it pushes the limiting plate 9 towards the center of the equipment; when it retracts, it pulls the limiting plate 9 back to its original position. The limiting assembly also includes multiple hinge frames 20, which are respectively disposed at both ends of the limiting plate 9 and the connecting plate 18. Connecting frames 19 are slidably connected to both sides of the housing 16. Sliding sliders 21 are slidably connected to the inner sides of both connecting frames 19, and two sliding sliders 21 are respectively disposed on the sides of the multiple hinge frames 20. When the limiting plate 9 moves, the hinge frame 20 swings accordingly. Its angle change is guided by the sliding of slider 1 21 within the connecting frame 19, ensuring that the limiting plate 9 always moves horizontally and avoids tilting. The limiting assembly also includes two sliders 22, which are fixedly connected to the sides of the two connecting frames 19 and slidably connected to the inner sides of both ends of the housing 16. The connecting frame 19 is slidably connected to the sliding grooves at both ends of the housing 16 via sliders 22, forming a second layer of guidance to ensure smooth movement of the connecting frame 19, thereby driving the entire hinge frame 20 system to move synchronously.

[0037] Reference Figure 2 , Figure 3 and Figure 4The lifting and pressing assembly includes two electric push rods 6, which are fixedly connected to both ends of the outer casing 1. A fixing plate 7 is fixedly connected to the ends of the two electric push rods 6, and a mold 8 is fixedly connected to the side of the fixing plate 7. The two electric push rods 6, fixed to both ends of the outer casing 1, achieve linear telescopic movement via an internal lead screw or hydraulic cylinder driven by a motor. When the pressing program is started, the electric push rods extend downwards synchronously, driving the fixing plate 7 and mold 8 connected to them to move vertically downwards. A second mold 10 is fixedly connected to the bottom of the outer casing 1. A pressing groove 13 is provided on the inner side of the second mold 10, and mold 8 is slidably connected to the inner side of the pressing groove 13. As the fixing plate 7 descends, mold 8 gradually inserts into the pressing groove 13 of the second mold 10, forming a closed structure of upper and lower molds. The lifting and pressing assembly also includes two heating tubes 14, both of which are located inside the mold 8. The input ends of the two heating tubes 14 are located inside the fixing plate 7. The two heating tubes 14 are integrated into the mold 8 and connected to the circuit via a power interface inside the fixing plate 7. When powered on, the heating tubes 14 generate heat, which is conducted to the surface of the mold 8, maintaining the mold 8 at a preset temperature. A second heating tube 15 is installed inside the mold 10, with its input end located at the end of the mold 10. The second heating tube 15 is integrated into the mold 10 and powered by an end interface, maintaining the mold 10 and the pressing groove 13 at a temperature matching that of the mold 8.

[0038] Reference Figure 1 and Figure 2 The conveying assembly includes two pulleys 11, which are rotatably connected to the inner side of the baffle 2. A conveyor belt 3 is fitted around the outer side of the two pulleys 11. A drive motor 12 is fixedly connected to the outer side of the baffle 2, with one of the pulleys 11 fixedly connected to the output end of the drive motor 12. The drive motor 12 drives the pulleys 11 to rotate, causing the conveyor belt 3 to run and convey the hot-formed steel crossbeams to be processed to the pressing groove 13 of the mold 10. A protective shell 5 is fixedly connected to the outer side of the baffle 2, and the protective shell 5 is fixedly connected to the outer side of the drive motor 12. During the conveying process, the protective shell 5 isolates the drive motor 12, preventing high temperature and dust from affecting the motor's lifespan. Multiple bases 4 are fixedly connected to the bottom of the outer shell 1 and the baffle 2. The bases 4 serve as the basic support components of the equipment, evenly distributing the overall weight of the equipment to the ground and preventing the equipment from tilting or collapsing due to gravity.

[0039] Working principle: First, start the drive motor 12 to drive the pulley 11 to rotate, so that the conveyor belt 3 runs and transports the hot-formed steel cross and longitudinal beams to be processed to the pressing groove 13 of the mold 2 10.

[0040] Then, the electric push rod 17 is activated to move the limiting plate 9 inward, thus limiting the steel laterally and ensuring its accurate positioning during the pressing process. As the limiting plate 9 moves, the hinge frame 20 moves accordingly and slides within the connecting frame 19 via the slider 21. Simultaneously, the connecting frame 19 slides on the housing 16 via the slider 22, forming a stable parallelogram structure. This ensures that both sides of the limiting plate 9 move synchronously, improving positioning accuracy.

[0041] Heating tube 14 and heating tube 15 heat molds 18 and 20 respectively, bringing the steel to the temperature required for thermoforming. When the electric push rod 6 drives the fixing plate 7 to descend, it moves mold 18 towards the pressing groove 13 of mold 20, applying pressure to the steel to complete the composite bending and pressing. Finally, the operator removes the pressed steel from the pressing groove 13 using external equipment.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
