Description

Technical Field

[0001] This utility model belongs to the field of C-shaped steel technology, specifically a transmission device for a C-shaped steel forming machine. Background Technology

[0002] C-shaped steel is automatically formed by C-shaped steel forming machines. In recent years, with social progress and the continuous development of the construction industry, the demand for C-shaped steel is increasing year by year.

[0003] Traditional flanging devices rely on independent clamping mechanisms or manual adjustments, which can easily lead to inconsistent flanging angles or workpiece displacement, affecting the dimensional accuracy of C-shaped steel. During stamping and flanging, the steel plate may shift due to uneven force, resulting in uneven flanging or forming errors. To address this, we propose a transmission device for a C-shaped steel forming machine. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution: a transmission device for a C-shaped steel forming machine, including a base and a worktable. A stabilizing block is provided on the worktable, and an arc plate is installed on the stabilizing block. Adjusting plates are hinged to both ends of the arc plate. Columns are provided on both sides of the worktable, and a top plate is connected between the tops of the two columns. A cylinder is installed on the top plate, and the telescopic end of the cylinder penetrates downward through the top plate and is connected to a connecting plate. A punch head is installed at the bottom of the connecting plate. Through holes are provided at both ends of the connecting plate, and the through holes are slidably connected to the columns. A rack is provided on the columns, and a transmission mechanism is provided in the through holes. The transmission mechanism is meshed with the rack, and the transmission mechanism includes two traction ropes, which are respectively connected to the ends of the two adjusting plates.

[0005] Furthermore, the transmission mechanism also includes gears and connecting rods. The gears can mesh with the rack. There are two gears, which are rotatably disposed in two through holes. The two ends of the connecting rod are fixedly connected to the two gears respectively. A winding part is provided in the middle of the connecting rod, and one end of the two traction ropes is fixedly connected to the winding part.

[0006] Furthermore, a locking structure is provided at the bottom of the end of the adjusting plate near the arc plate.

[0007] Furthermore, a tension spring is connected between the end of the adjusting plate away from the arc plate and the worktable.

[0008] Furthermore, a guide post is provided between the stamping head and the connecting plate, and a compression spring is sleeved on the guide post.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model utilizes a transmission mechanism composed of a rack, pinion, connecting rod, and traction rope to convert the downward pressing motion of the stamping head into the flanging and clamping action of the adjusting plate. This avoids the need for an additional drive device, resulting in a simple structure and good synergy. During the stamping process, the compression spring provides a buffering effect, reducing impact force and extending the service life of the equipment. The tension spring allows the adjusting plate to automatically reset after stamping, improving operational efficiency, reducing manual intervention, and making it suitable for automated production environments.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figure 1 The present invention includes a base 1 and a workbench 2. A stabilizing block 3 is provided on the workbench 2. An arc plate 5 is installed on the stabilizing block 4. Adjusting plates 6 are hinged to both ends of the arc plate 5. Columns 7 are provided on both sides of the workbench 2. A top plate 8 is connected between the tops of the two columns 7. A cylinder 9 is installed on the top plate 8. The telescopic end of the cylinder 9 passes through the top plate 8 and is connected to a connecting plate 10. A punch head 11 is installed at the bottom of the connecting plate 10. Through holes 13 are provided at both ends of the connecting plate 10. The through holes 13 are slidably connected to the columns 7. A rack 14 is provided on the columns 7. A transmission mechanism is provided in the through holes 13. The transmission mechanism is meshed with the rack 14. The transmission mechanism includes two traction ropes 15, which are respectively connected to the ends of the two adjusting plates 6.

[0017] Depend on Figure 2 The transmission mechanism also includes a gear 16 and a connecting rod 17. The gear 16 can mesh with the rack 14. There are two gears 16, which are rotatably disposed in two through holes 13 respectively. The two ends of the connecting rod 17 are fixedly connected to the two gears 16 respectively. A winding part 18 is provided in the middle of the connecting rod 17, and one end of the two traction ropes 15 is fixedly connected to the winding part 18.

[0018] A locking structure is provided at the bottom of the end of the adjusting plate 6 near the arc plate 5. By setting the locking structure, the opening angle of the adjusting plate 6 can be limited, and the adjusting plate 6 can be prevented from over-rotating.

[0019] A tension spring is connected between the end of the adjusting plate 6 away from the arc plate 5 and the worktable 2. By setting the tension spring, when the adjusting plate 6 flips inward, the tension spring can be stretched to store energy. At the end of the stamping stage, the energy stored in the tension spring is released, which can drive the adjusting plate 6 to reset.

[0020] A guide post 19 is provided between the stamping head 11 and the connecting plate 10. A compression spring 12 is sleeved on the guide post 19. By providing the compression spring 12, the stamping head 11 can be pressed against the top of the workpiece, providing buffer during the continued pressing process, and enabling the connecting plate 10 to continue to descend, thereby driving the transmission mechanism to work.

[0021] Working principle: After the workpiece is placed on the arc plate 5, the adjusting plate 6 maintains its initial position under the action of the tension spring, and its opening angle is limited by the locking structure to ensure the workpiece is stably fixed. After the cylinder 9 is started, its telescopic end pushes the connecting plate 10 downward. The connecting plate 10 slides on the column 7 through the through hole 13. At the same time, the punch head 11 is pressed down smoothly under the action of the guide column 19 and the compression spring 12 to ensure the stability of the punching process. When the punch head 11 contacts the workpiece and continues to compress downward, the compression spring 12 provides buffering, allowing the connecting plate 10 to continue to descend, thereby driving the transmission mechanism to work. As the connecting plate 10 descends, the gear 16 inside the through hole 13 meshes with the rack 14 on the column 7 and rotates. The gear 16 transmits power through the connecting rod 17, causing the winding part 18 to drive the two traction ropes 15 to tighten. The other end of the traction ropes 15 is connected to two adjusting plates 6 respectively, causing the adjusting plates 6 to flip inward, thereby clamping the workpiece to further stabilize its position. When the stamping is completed, the cylinder 9 returns and drives the connecting plate 10 to rise. The gear 16 rotates in the opposite direction under the action of the rack 14, the traction ropes 15 loosen, and the adjusting plates 6 reset under the action of the tension spring, releasing the workpiece and completing the entire stamping work cycle.
