Description

Technical Field

[0001] The utility model belongs to the technical field of steel processing, in particular to equipment for forming U-shaped steel. Background Art

[0002] Bent U-shaped steel is used as a supporting member in buildings, bridges, tunnels, mine support and other fields. Generally, the U-shaped steel is cold-bent using a three-roll bending machine.

[0003] Currently, a Chinese utility model with publication number CN211637858U discloses a U-shaped steel bending tool, comprising a base plate, a fixing mechanism and a bending mechanism provided on the base plate, the fixing mechanism comprising a fixed pressure plate and a movable pressure plate arranged perpendicular to the base plate, the movable pressure plate being detachably connected to the fixed pressure plate via an adjusting bolt, and a positioning block provided on the fixed pressure plate; the bending mechanism comprising a fixed plate fixedly connected to the base plate, movable arms rotatably connected at the center of the circle on both sides of the fixed plate, a movable plate provided between the two movable arms, a gap formed between the movable plate and the fixed plate for the U-shaped steel to pass through, and gaps formed between the axial sides of the movable plate and the two movable arms for inserting the side edges of the U-shaped steel. This utility model can bend and shape U-shaped door and window frames, effectively solving the problem of bending and deformation of the two sides of the U-shaped steel during processing, and has a simple structure, is convenient and quick to use, and is easy to promote.

[0004] During the processing of existing U-shaped steel, a cylinder typically drives a central roller to press against the rollers on either side. The central roller bends the center of the steel into an arc, while the rollers on either side squeeze the ends of the steel, forming a U-shape. However, the cylinder needs to be reset before it can re-activate the central roller for bending. During this reset, the cylinder exerts little force and is therefore unable to bend the steel. Consequently, existing equipment can only perform a single bend in each reciprocating movement of the central roller against the rollers on either side, resulting in low steel forming efficiency. Furthermore, since the three rollers cannot be adjusted in position, the steel cannot be bent into U-shaped grooves of varying sizes, making it less practical. Utility Model Content

[0005] The purpose of the utility model is to provide a U-shaped steel forming device, which has the advantage that the stamping roller can alternately bend the steel placed on both sides during the reciprocating motion, thereby improving the processing efficiency and facilitating the bending of the steel into a variety of U-shapes with different inner diameters.

[0006] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: U-shaped steel forming equipment includes a workbench, the top of the workbench is slidably connected to a sliding plate, one side of the bottom of the workbench is bolted to a motor, the output end of the motor is bolted to a reciprocating screw connected to the workbench for rotation, the surface thread of the reciprocating screw is sleeved with a screw sleeve bolted to the bottom of the sliding plate, limit blocks are provided on both sides of the top of the workbench, the bottom of the limit block is provided with a support block connected to the workbench for sliding, the top of the support block is welded with a rotating shaft connected to the limit block for rotation, both ends of the limit block are bolted to bending rollers, and both sides of the top of the sliding plate are provided with stamping rollers, and the stamping rollers are installed between the two limit blocks.

[0007] Using this technical solution, a motor drives a reciprocating screw, which engages the screw sleeve thread, allowing the stamping rollers on either side of the top of the sliding plate to reciprocate between two limit blocks, thereby alternately stamping and bending the steel into a U-shape. This improves the efficiency of steel processing and forming. The two limit blocks allow the position to be adjusted by sliding on the top of the workbench, while the stamping rollers can be removed and replaced from the top of the sliding plate. The stamping rollers and two bending rollers can stamp and bend the steel into U-shapes of varying inner diameters, thereby improving the practicality of the equipment and facilitating processing according to production needs.

[0012] The utility model is further configured as follows: a supporting base plate is bolted to the bottom of the supporting column.

[0013] By adopting the above technical solution, the ground contact area at the bottom of the support column is increased, thereby improving the stability of the workbench when it is placed.

[0014] The utility model is further configured as follows: both ends of the reciprocating screw rod surface are fixedly sleeved with limit disks, and a buffer pad used in conjunction with the screw rod sleeve is adhered to one side of the two limit disks close to each other.

[0015] By adopting the above technical solution, the left and right sliding positions of the screw sleeve are limited and buffered, thereby reducing the vibration caused by the collision.

[0016] The utility model is further configured as follows: both sides of the top of the sliding plate are bolted with pull-back blocks used in conjunction with the punching roller.

[0017] By adopting the above technical solution, after the stamping roller slides out from between the two limit blocks, the steel material bent into the U shape can be brought out by using the pull-back block.

[0022] 2. The position of the workbench can be adjusted by sliding on the top of the workbench through two limit blocks. At the same time, the stamping roller can be removed and replaced from the top of the sliding plate. The stamping roller and two bending rollers can bend the steel into U-shaped shapes with different inner diameters, thereby improving the practicality of the equipment and facilitating processing according to production needs.

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1: Reference Figure 1 、 Figure 2 The equipment for forming U-shaped steel includes a workbench 1, a sliding plate 2 is slidably connected to the top of the workbench 1, a motor 3 is bolted to one side of the bottom of the workbench 1, the output end of the motor 3 is bolted to a reciprocating screw 4 rotatably connected to the workbench 1, and the surface of the reciprocating screw 4 is threadedly sleeved with a screw sleeve 5 bolted to the bottom of the sliding plate 2. Limit blocks 7 are provided on both sides of the top of the workbench 1, and a support block 12 slidably connected to the workbench 1 is provided at the bottom of the limit block 7. A rotating shaft 13 is welded to the top of the support block 12 and is rotatably connected to the limit block 7. Bending rollers 8 are bolted to both ends of the limit block 7, and stamping rollers 6 are provided on both sides of the top of the sliding plate 2. The stamping rollers 6 are installed between the two limit blocks 7. The reciprocating screw 4 is driven by the motor 3 to engage with the screw sleeve 5, so that the stamping rollers 6 on both sides of the top of the sliding plate 2 can reciprocate between the two limit blocks 7, thereby alternately stamping and bending the steel into a U shape. Improve the efficiency of steel processing and forming.

[0029] refer to Figure 1 、 Figure 2 The four corners of the bottom of the workbench 1 are each provided with a support column 17. An extension column 18, bolted to the workbench 1, is slidably connected to the interior of the support column 17. A limit bolt 19, threadedly connected to the extension column 18, is threadedly connected to one side of the support column 17. By sliding the extension column 18 up and down within the support column 17 and tightening it with the limit bolt 19, the height of the workbench 1 can be adjusted, making it easier for workers to work.

[0030] refer to Figure 1 、 Figure 2 The bottom of the support column 17 is bolted with a support base plate 20. The ground contact area of ​​the bottom of the support column 17 is increased to improve the stability of the workbench 1 when it is placed.

[0031] refer to Figure 2The two ends of the reciprocating screw 4 are fixedly sleeved with limit plates 21, and the side of the two limit plates 21 close to each other is bonded with a buffer pad 22 used in conjunction with the screw sleeve 5. The left and right sliding position of the screw sleeve 5 is limited and buffered, thereby reducing the vibration caused by collision.

[0032] Brief description of the usage process: By turning on the motor 3 to drive the reciprocating screw 4 to rotate, so that the reciprocating screw 4 and the screw sleeve 5 are threadedly engaged, the workbench 1 is used to limit the sliding plate 2, thereby driving the sliding plate 2 to slide back and forth on the top of the workbench 1. When the stamping roller 6 on one side of the top of the sliding plate 2 slides between the two limit blocks 7, the stamping roller 6 and the two bending rollers 8 cooperate with each other to extrude and deform the steel, thereby bending the center of the steel into a U shape. At the same time, the friction between the bending roller 8 and the surface of the steel drives the limit block 7 to rotate on the top of the support block 12 using the rotating shaft 13, thereby allowing the limit block 7 to rotate a certain distance, so that the two bending rollers 8 can fully extrude the two ends of the steel, so that the two ends of the steel are also squeezed into a U shape. At this time, the stamping roller 6 on the other side slides out from between the two limit blocks 7, and new steel can be put in. Therefore, when the motor 3 drives the screw sleeve 5 to slide to the other side, the steel originally bent into a U shape can slide out from between the two limit blocks 7 and the stamping roller 6, and the newly put in steel can be used for a new round of stamping and bending.

[0033] Example 2: Reference Figure 1 、 Figure 2 、 Figure 3 , equipment for forming U-shaped steel materials, threaded shafts 9 that are slidably connected to the punching roller 6 are welded on both sides of the top of the sliding plate 2, a support plate 10 is welded on the surface of the bottom of the threaded shaft 9, and a threaded pressure ring 11 that is clamped to the top of the punching roller 6 is threadedly sleeved on the surface of the top of the threaded shaft 9. A sliding block 14 that is slidably connected to the workbench 1 is welded to the bottom of the support block 12, and the sliding block 14 is rotatably connected to a threaded push rod 15 that is threadedly connected to the workbench 1 on the side away from the sliding plate 2, and a rotating plate 16 is welded on the end of the threaded push rod 15 that is away from the sliding block 14. The position can be adjusted by sliding on the top of the workbench 1 through two limit blocks 7, and the punching roller 6 can be disassembled and replaced from the top of the sliding plate 2. The punching roller 6 and the two bending rollers 8 can punch and bend the steel into U-shapes with different inner diameters, thereby improving the practicality of the equipment and facilitating processing according to production needs.

[0034] refer to Figure 1 、 Figure 2 The two sides of the sliding plate 2 top are all bolted with the pull-back block 23 used in conjunction with the punching roller 6. After the punching roller 6 slides out between the two limit blocks 7, the pull-back block 23 can be utilized to bring the steel material bent into the U shape out.

[0035] refer to Figure 1, the top of the workbench 1 is respectively close to both sides of the two limit blocks 7 and are marked with a scale 24 used in conjunction with the support block 12. It is convenient to finely observe and adjust the moving distance of the limit block 7, thereby ensuring that the moving distance of the limit blocks 7 on both sides is consistent.

[0036] Brief description of the usage process: Remove the threaded pressure ring 11 from the threaded shaft 9 by twisting it, and replace the punching roller 6 according to the size of the U-shaped groove to be bent into the steel. After the threaded shaft 9 passes through the punching roller 6, place the punching roller 6 on the top of the support plate 10, and then re-twist the threaded pressure ring 11 to engage with the thread of the threaded shaft 9 to fix the punching roller 6 on the surface of the threaded shaft 9. After that, the threaded push rod 15 is rotated by rotating the rotating plate 16 to engage with the thread of the workbench 1, so that the workbench 1 limits the sliding block 14 to slide. The sliding block 14 can drive the top limit block 7 of the support block 12 to slide on both sides of the workbench 1, adjust the distance between the bending roller 8 and the punching roller 6, and make the bending roller 8 adapt to the punching roller 6 with different inner diameters, so that the punching roller 6 and the two bending rollers 8 can bend the U-shape of the steel into different inner diameters.
