Description

Technical Field

[0001] This utility model relates to the field of hooking and cutting device technology, and in particular to a hydraulically driven bidirectional hooking and cutting device for U-shaped roll forming plates. Background Technology

[0002] U-shaped channel steel is a common structural component in the fields of building steel structures, automotive parts, and warehouse racking. It is usually manufactured from coils through a continuous roll forming production line. At the end of the production line, the continuously formed U-shaped material needs to be cut into fixed-length products. The hydraulically driven bidirectional hook-cutting device for U-shaped roll forming plates is a special equipment adapted to the processing scenarios of U-shaped roll forming plates. Its design is closely integrated with the actual operation requirements of plate processing. The device uses hydraulic drive as the core power source and can achieve stable operation of the hook-cutting mechanism through precise hydraulic control, meeting the force and speed requirements of bidirectional hook-cutting operations. It can simultaneously perform hook-shaped cutting on both sides of the U-shaped roll forming plate according to the processing specifications, and can also flexibly adjust the hook-cutting depth and angle to adapt to the processing standards of different sized plates.

[0003] During use, the device's positioning structure provides a stable clamping grip on the U-shaped roll-formed plate, preventing deviation during cutting and ensuring the flatness and precision of the cut. Simultaneously, the hydraulic system's buffer design reduces the impact during cutting, protecting the plate edges from damage and extending the lifespan of the device components. This type of device efficiently completes the cutting process of U-shaped roll-formed plates, enabling continuous processing without complex manual intervention. This provides reliable equipment support for the mass production of U-shaped roll-formed plates. However, current cutting devices use large punch presses and molds for vertical punching. Due to the instantaneous vertical force, burrs and even minor deformations are easily generated when cutting thick plates, affecting the product's cross-sectional quality. Furthermore, the investment and maintenance costs of the punching equipment are high, thus reducing the device's efficiency. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides a hydraulically driven bidirectional hooking and cutting device for U-shaped roll forming plates, including a base 10, a workbench 16 fixedly connected to the top of the base 10, a conveying device 13 provided on the top of the workbench 16, an H-shaped plate 7 fixedly connected to the top left of the conveying device 13, hydraulic driving devices 6 fixedly connected to the front and rear sides of the H-shaped plate 7, the output end of the hydraulic driving device 6 passing through the front and rear sides of the H-shaped plate 7 and fixedly connected to hooking and cutting knife units 3, a back-facing slider mechanism 9 provided on the top of the hooking and cutting knife units 3, hooking and cutting blades 8 provided between adjacent hooking and cutting knife units 3, an upper mold base 2 provided on the inner side of the hooking and cutting knife units 3, a lower mold base 1 provided on the front side of the upper mold base 2, a supporting and positioning U-shaped profile cavity 4 provided on the inner bottom of the lower mold base 1, and a hooking and cutting slide rail 5 provided on the inner top of the H-shaped plate 7.

[0028] Specifically, the conveying device 13 is responsible for conveying materials. An H-shaped plate 7 is firmly fixed to the top left side of the conveying device 13, providing a stable support platform. Hydraulic drive devices 6 are fixedly connected to the front and rear sides of the H-shaped plate 7, respectively. These hydraulic drive devices 6 have strong power output capabilities, and their output ends pass through the front and rear sides of the H-shaped plate 7 and are fixedly connected to the hook-cutting unit 3, providing power support for the movement of the hook-cutting unit 3. A back-sliding slider mechanism 9 is provided on the top of the hook-cutting unit 3, enabling the hook-cutting unit 3 to achieve the required trajectory movement during operation. Hook-cutting blades 8 are precisely positioned between adjacent positions of two hook-cutting units 3, and the hook-cutting blades 8 perform the cutting task. In addition, an upper mold base 2 is provided inside the hook-cutting unit 3, and a lower mold base 1 is provided at the corresponding position on the front side of the upper mold base 2. The upper mold base 2 and the lower mold base 1 cooperate with each other to complete specific processing operations.

[0029] Please see the appendix Figure 4 - Appendix Figure 6 A storage box 12 is slidably connected to the bottom left side of the workbench 16. A support frame 11 is fixedly connected to the bottom front and rear sides of the lower mold base 1. An anti-slip pad 17 is fixedly connected to the bottom of the support frame 11. A baffle 15 is fixedly connected to the top right side of the workbench 16. A handle 14 is fixedly connected to the front center of the storage box 12. Multiple hydraulic drive devices 6 and hook cutting knife units 3 are all designed symmetrically.

[0030] Specifically, a baffle 15 is fixedly connected to the top right side of the clearance workbench 16. The baffle 15 serves to block and position materials or parts from accidentally slipping during processing. In conjunction with the storage box 12, a handle 14 is fixedly connected to the center of its front side, while an anti-slip pad 17 is fixedly connected to the bottom of the support frame 11. The anti-slip pad 17 can effectively increase the friction with the contact surface, preventing the device from sliding due to vibration during operation, and further improving the stability and safety of the device.

[0031] Working principle: Initially, the upper mold base 2 is in the upper position, and the hook-cutting blade 8 is located inside the center of the U-shaped profile. The forming plate is fed forward to the set length under the drive of the conveying device 13, and then pressed and moved downward. At this time, the hydraulic drive device 6 pushes the upper mold base 2 to move. Then, the lower mold base 1 presses the inside of the U-shaped profile and firmly fixes it in the cavity 4 of the lower mold support to prevent movement during the shearing process. With the continued movement of the upper mold base 2, the components fixed on it push the two back-to-back slider mechanisms 9. The two back-to-back slider mechanisms 9 carry the hook-cutting blade 8 and precisely slide along the horizontal guide rail to both sides of the U-shaped profile to complete the shearing. When the cutting edge of the hook-cutting blade 8 slides during the sliding process, it starts from the middle position inside the U-shaped profile and gradually shears towards the root on both sides. Since the shearing force is applied symmetrically, the lateral force is completely absorbed. The opening size of the U-shaped profile remains unchanged. When the upper die 2 reaches the dead point, the blade completely cuts off the two side roots of the U-shaped profile. Then, the hydraulic drive device 6 pushes the upper die 2 to move. After that, the opposing slider mechanism 9 moves towards each other under the action of the hydraulic drive device 6, driving the hook-cutting blade 8 to return to the initial center position from both sides of the cut workpiece, waiting for the next work cycle. Therefore, it can achieve high precision and no deformation. It adopts a cutting method from the inside out and synchronous left and right symmetrical, which perfectly cancels the lateral force generated by single-sided cutting. At the same time, the cutting quality is good, and the cutting process is stable and continuous. Compared with stamping cutting, the cutting is burr-free, flat and smooth, and no secondary processing is required. It can be directly used as the end face of the finished product. At the same time, it can realize the full automation of feeding, positioning, cutting and unloading, and the production efficiency is high.

[0032] 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.
