Description

Technical Field

[0001] This utility model relates to the field of door sill forming and processing technology, specifically to a roll forming machine for processing door sills of fire-fighting equipment. Background Technology

[0002] The door sills of vehicles transporting fire-fighting equipment (such as fire trucks and emergency rescue transport vehicles) need to have high structural strength and anti-slip performance. They are usually made by rolling metal sheets with a roll forming machine to form specific patterns.

[0003] The forming rollers of existing roll forming machines are mostly integrated structures. On the one hand, the outer layer is in direct contact with the metal sheet during the roll forming process, which is prone to wear due to friction. After wear, the entire forming roller needs to be replaced, which is costly. On the other hand, if different pattern types of door sill plates need to be processed, the entire forming roller assembly needs to be replaced. Keeping multiple forming rollers in stock will increase the equipment investment cost, and the replacement will take a long time, affecting production efficiency and making it difficult to meet the diverse processing needs of fire equipment door sill plates. Utility Model Content

[0004] In view of the problems existing in the roll forming machine for processing door sill plates of fire-fighting equipment, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a roll forming machine for processing fire equipment door sill plates, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A roll forming machine for processing fire equipment door sill plates includes a base plate and a turntable. The turntable is rotatably mounted on one side of the upper surface of the base plate. A first vertical plate is fixedly mounted on the upper surface of the turntable. A second vertical plate is slidably mounted on the upper surface of the base plate, on the side away from the turntable. A transmission mechanism for moving the second vertical plate is mounted on the upper surface of the base plate, below the second vertical plate. Two rotating rods are rotatably mounted from top to bottom on the side of the first vertical plate closest to the second vertical plate. A pressure roller is fixedly sleeved on the wall of each rotating rod. Patterned convex sleeves and patterned concave sleeves are respectively sleeved on the outer walls of the two pressure rollers. Limiting mechanisms for restricting the movement of the patterned convex sleeves and patterned concave sleeves are provided on both sides of the pressure rollers. Two first motors are fixedly mounted on the side of the first vertical plate away from the second vertical plate. The output ends of the two first motors are respectively fixedly connected to one end of the corresponding rotating rod.

The slider is slidably disposed inside the groove, and the lead screw is rotatably disposed inside the groove. The slider and the wall of the lead screw are threadedly connected. A second motor is fixedly disposed on one side of the base plate, and the output end of the second motor is fixedly connected to one end of the lead screw.

[0009] Preferably, the limiting mechanism includes a first retaining ring and a second retaining ring. The first retaining ring is fixedly disposed on the side of the pressure roller away from the second vertical plate. A fixed plate is rotatably fixedly disposed on the side of the second vertical plate close to the pressure roller and at a position corresponding to the pressure roller. The second retaining ring is rotatably sleeved on the outer wall of the fixed plate. The two ends of the patterned convex sleeve and the patterned concave sleeve respectively abut against the corresponding first retaining ring and the second retaining ring. A wedge-shaped groove is provided on one side of the pressure roller. A wedge-shaped block is engaged inside the wedge-shaped groove.

[0012] Preferably, both the patterned convex sleeve and the patterned concave sleeve are coated with a wear-resistant coating.

[0013] Preferably, both of the first motors are geared motors.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a roll forming machine for processing fire equipment door sill plates.

[0025] Reference Figure 1-4 A roll forming machine for processing fire equipment door sill plates includes a base plate 1 and a turntable 2. The turntable 2 is rotatably disposed on one side of the upper surface of the base plate 1. A first vertical plate 3 is fixedly disposed on the upper surface of the turntable 2. A second vertical plate 9 is slidably disposed on the upper surface of the base plate 1 on the side away from the turntable 2. A transmission mechanism for driving the second vertical plate 9 is disposed on the upper surface of the base plate 1 and below the second vertical plate 9. Two rotating rods 4 are rotatably disposed from top to bottom on the side of the first vertical plate 3 near the second vertical plate 9. A pressure roller 5 is fixedly sleeved on the rod wall of the rotating rod 4. The outer walls of each pressure roller 5 are respectively fitted with patterned convex sleeves 6 and patterned concave sleeves 7. The surfaces of the patterned convex sleeves 6 and patterned concave sleeves 7 are coated with wear-resistant coatings to improve their wear resistance. Limiting mechanisms are provided on both sides of the pressure roller 5 to restrict the movement of the patterned convex sleeves 6 and patterned concave sleeves 7. Two first motors 8 are fixedly installed on the side of the first vertical plate 3 away from the second vertical plate 9. The output ends of the two first motors 8 are respectively fixedly connected to one end of the corresponding rotating rod 4. Both first motors 8 are geared motors, which can provide a large and stable transmission force.

[0026] Reference Figure 1-4 The transmission mechanism includes a lead screw 11 and a slider 10. A groove is provided on the upper surface of the base plate 1 and below the second vertical plate 9. The slider 10 is slidably disposed inside the groove, and the lead screw 11 is rotatably disposed inside the groove. The slider 10 is threadedly connected to the wall of the lead screw 11. A second motor 13 is fixedly disposed on one side of the base plate 1. The output end of the second motor 13 is fixedly connected to one end of the lead screw 11. A slider 12 is arranged parallel to one side of the lead screw 11. The two ends of the slider 12 are fixedly connected to the inner wall of the corresponding groove. One side of the slider 10 is movably sleeved with the slider 12, so that the slider 10 can slide stably.

[0027] Reference Figure 1-4 The limiting mechanism includes a first retaining ring 14 and a second retaining ring 16. The first retaining ring 14 is fixedly disposed on the side of the pressure roller 5 away from the second vertical plate 9. The second vertical plate 9 is rotatably fixedly disposed on the side of the pressure roller 5 and at the position corresponding to the pressure roller 5. The second retaining ring 16 is rotatably sleeved on the outer wall of the fixed plate 15. The two ends of the patterned convex sleeve 6 and the patterned concave sleeve 7 respectively abut against the corresponding first retaining ring 14 and the second retaining ring 16. A wedge-shaped groove is opened on one side of the pressure roller 5. A wedge-shaped block is engaged inside the wedge-shaped groove. One side of the wedge-shaped block is fixedly connected to the corresponding patterned convex sleeve 6 and the patterned concave sleeve 7. Multiple through holes are opened on the surface of the second retaining ring 16. A limiting rod 17 is slidably disposed inside the through holes. One end of the limiting rod 17 is fixedly connected to the corresponding pressure roller 5, so that the second retaining ring 16 can rotate with the pressure roller 5.

[0028] In this invention, during use, the second motor 13 is first started, driving the lead screw 11 to rotate. Since the slider 10 is threadedly connected to the lead screw 11 and movably connected to the slide rod 12, the slider 10 slides along the slide groove and drives the second vertical plate 9 to move away from the first vertical plate 3, exposing one end of the pressure roller 5. At this time, the turntable 2 is rotated, driving the first vertical plate 3 and the pressure roller 5 to rotate, rotating the end of the pressure roller 5 to a forward position. At this point, the limiting position can be released: by operation, the second retaining ring 16 slides along the fixed plate 15, and the limiting rod 17 moves within the through hole. When the second retaining ring 16 separates from the patterned convex sleeve 6 and the patterned concave sleeve 7, since the patterned convex sleeve 6 and the patterned concave sleeve 7 are engaged with the wedge groove of the pressure roller 5 by a wedge block, only axial force is needed to remove the patterned convex sleeve 6. The sleeve 6 and the patterned concave sleeve 7 are removed from the pressure roller 5. If the worn patterned sleeve needs to be replaced, the wedge blocks of the new patterned convex sleeve 6 and the patterned concave sleeve 7 are aligned with the wedge grooves of the pressure roller 5 and inserted, so that the two ends of the patterned sleeve abut against the first retaining ring 14 and the second retaining ring 16 respectively. Then, the second motor 13 is started in reverse, so that the second vertical plate 9 is close to the first vertical plate 3, driving the second retaining ring 16 to press the patterned sleeve. After the replacement is completed, the first motor 8 is started. The first motor 8 drives the rotating rod 4 and the pressure roller 5 to rotate, and feeds the metal plate between the two pressure rollers. The plate is rolled by the patterned convex sleeve 6 and the patterned concave sleeve 7 to form a sill plate with a specific pattern, which meets the needs of transporting fire-fighting equipment. In the whole process, the patterned sleeve can be replaced individually, reducing maintenance costs, and different patterns can be easily replaced to adapt to diverse processing needs.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
