Description

Technical Field

[0001] This utility model relates to the field of steel formwork equipment technology, and more specifically, to a bending device for steel formwork. Background Technology

[0002] A steel formwork bending device is a piece of equipment used for precise bending of steel formwork. It is widely used in the fabrication of building formwork in construction, bridge, tunnel and other engineering projects. A steel formwork bending device typically consists of the following parts: bending tools: including upper and lower dies, responsible for bending the steel formwork; hydraulic system: providing the necessary pressure and power to ensure smooth bending; control system: used to control the bending angle and speed; some advanced equipment may also be equipped with a CNC system. The steel formwork bending device mainly utilizes the pressure generated by the hydraulic system to clamp the steel formwork between the upper and lower dies. The relative movement of the upper and lower dies causes plastic deformation of the formwork, thereby achieving bending. Since the steel formwork workpiece is moved and its bending position adjusted by the operator during the bending process, and the size of the steel formwork workpiece varies, it is inconvenient for the operator to move and operate when some steel formwork workpieces are large. Therefore, it is necessary to provide bending support for the steel formwork workpiece.

[0003] In related technologies, during the use of a bending machine, a support frame is generally installed on the front side of the bending machine to support the steel template workpiece, so that the operator can adjust the bending position of the steel template workpiece for use.

[0004] However, in the current use of bending machines, the support frame is generally an integrated frame type, which can only support steel template workpieces. When bending larger steel template workpieces by two operators, it is difficult to ensure the synchronization of the two operators' operations, which makes the support operation of steel template workpieces inconvenient and affects the convenience and synchronization of the support operation of the bending machine.

An upper mold 2 is installed at the top inside the bending machine 1, and a lower mold 3 is installed at the bottom inside the bending machine 1. This provides a support medium that can move and follow the steel formwork workpiece. The support range can be adjusted according to the direct support requirements of the external steel formwork workpiece, so that the workers can perform synchronous bending and adjustment operations on the steel formwork workpiece. This avoids the situation where it is difficult to perform synchronous bending adjustments when using the bending machine 1, thus improving the convenience and synchronization of the support operation of the bending machine 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the bending support mechanism includes a support rail 4, which is movably connected to the front side of the bending machine 1. Support seats 5 are slidably connected to both sides of the front side of the support rail 4. A support head 6 is movably connected to the inside of the support seat 5 via a pivot pin. A support frame 7 is movably connected to the front side of the support head 6. A support translation mechanism is fixedly connected to both sides of the support head 6. Based on the required support range of the external steel template workpiece, the support seat 5 is held and the support frame 7 is translated via the support head 6 to adjust the support range of the support frame 7. Then, the support frame 7 is moved forward to adjust its support length. Finally, the external steel template workpiece is placed on top of the support frame 7 and supported by the support... The support frame 7 fixes the steel formwork workpiece, allowing workers to perform synchronous adjustment operations on the support of the steel formwork workpiece. The support translation mechanism includes a translation frame 8, a translation opening 9, and a translation block 10. The translation frame 8 is fixedly connected to both sides of the support head 6, the translation opening 9 is opened on the outside of the translation frame 8, and the translation block 10 is movably connected to the inside of the translation opening 9. The inner side of the translation block 10 is fixedly connected to the outer side of the support frame 7, which allows for translational connection between the support frame 7 and the support head 6. This enables workers to adjust the support position of the support frame 7 according to the support range requirements of the steel formwork workpiece, avoiding situations where it is difficult to adjust the support position when using the support frame 7, thus improving the flexibility of the support frame 7.

The bottom of the screw rod 14 is rotatably connected to the top of the force-applying seat 11, which can provide a medium for the user to apply clamping force to the force-applying frame 12, thus improving the convenience of the force-applying frame 12 clamping operation.

[0033] Reference Figures 2-3 In a preferred embodiment, a slide 15 is fixedly connected to the bottom of the force-applying seat 11, and slide rails 16 are movably connected to both sides of the slide 15. The outer side of the slide rails 16 is fixedly connected to the inner wall of the support frame 7, which can prevent the force-applying seat 11 and the support frame 7 from sliding and thus improve the connection effect between the force-applying seat 11 and the support frame 7. A lifting groove 17 is provided on the front side of the top of the force-applying seat 11 and the slide 15. A lifting column 18 is movably connected inside the lifting groove 17. The top of the lifting column 18 is fixedly connected to the bottom of the force-applying frame 12, which can perform lifting and lowering connection between the force-applying frame 12 and the force-applying seat 11, thus improving the lifting and lowering connection effect between the force-applying frame 12 and the force-applying seat 11.

[0034] Reference Figures 2-4 In a preferred embodiment, adjusting cylinders 19 are fixedly connected to both sides of the front side of the bending machine 1. Adjusting frames 20 are magnetically connected inside the adjusting cylinders 19. The inner side of the adjusting frame 20 is fixedly connected to the outer side of the support rail 4, which provides a medium for users to adjust the height of the support rail 4, thus improving the adaptability of the support rail 4. A screw cylinder 21 is fixedly connected to the top of the front side of the adjusting cylinder 19. A stud 22 is threaded inside the screw cylinder 21. The rear side of the stud 22 contacts the front side of the adjusting frame 20, which can be used to position the adjusted adjusting frame 20 and the adjusting cylinder 19, thus improving the convenience of positioning the adjusting frame 20 and the adjusting cylinder 19.

[0035] Specifically, the working process or principle of this steel formwork bending device is as follows: During use, based on the actual support height requirements of the external steel formwork workpiece, the handheld adjustment frame 20 drives the support rail 4 for lifting and lowering adjustment. The support rail 4 changes the support height of the support base 5, support head 6, and support frame 7. Then, the handheld stud 22 rotates in conjunction with the screw cylinder 21 to tighten and position the adjusted stud and cylinder 19. Next, based on the actual support range requirements of the external steel formwork workpiece, the handheld support base 5 drives the support frame 7 to move horizontally via the support head 6, adjusting the support range of the support frame 7. Then, the handheld support frame 7 moves forward to adjust its support length. At this time, the support base 5 moves outside the support rail 4, performing a horizontal connection between the support head 6, support rod, and support rail 4. Simultaneously, the horizontal block 10 follows the support frame 7, moving inside the horizontal opening 9 through the horizontal frame 8 to perform a horizontal connection between the support frame 7 and support head 6. Subsequently… The external steel template workpiece is placed on top of the support frame 7, behind the force-applying seat 11 and at the bottom of the force-applying frame 12. At this time, the force-applying seat 11 can be held and the force-applying frame 12 can be moved according to the actual placement of the steel template workpiece. The positions of the force-applying seat 11 and the force-applying frame 12 can be adjusted. At the same time, the slide 15 moves with the force-applying seat 11 inside the slide rail 16 to make a sliding connection between the force-applying seat 11 and the support frame 7. Then, the screw 14 is rotated to engage the screw hole 13 to apply a downward threaded force to the force-applying frame 12, so that the force-applying frame 12 can clamp and stabilize the steel template workpiece and the support frame 7. At this time, the lifting column 18 moves with the force-applying frame 12 inside the lifting groove 17 to make a lifting connection between the force-applying frame 12 and the slide 15. Then, the workers can adjust the position of the steel template workpiece according to the actual bending position of the steel template workpiece. During this process, the support frame 7 moves with the steel template workpiece to ensure the synchronization of the support adjustment position of the steel template workpiece.

[0036] It should be noted that the bending machine 1, the upper mold 2 and the lower mold 3 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
