Description

Technical Field

[0001] This utility model relates to the field of cold bending forming machine technology, and in particular to a guide device for a cold bending forming machine. Background Technology

[0002] A cold bending forming machine is a machine that uses sequentially arranged multi-pass forming rollers to continuously bend metal sheets and strips laterally to produce profiles with specific cross-sections. The front end of the pressure rollers in a cold bending forming machine is equipped with a guiding device to direct the movement of the coil and prevent it from shifting during travel.

[0003] Patent CN218310498U discloses a guiding device for a cold bending forming machine. This device uses the elastic force of springs to bring two sets of movable plates closer together, which in turn brings the fixed shafts on both sides closer to the guide wheels. The two sets of guide wheels contact the steel coil, thus limiting its lateral movement. The rotation of the guide wheels relative to the fixed shafts guides the steel coil. While this device can quickly compress and limit coils of different widths, it relies on springs to compress the two sets of movable plates and guide wheels to compress and limit the coil. If the compression force is insufficient, the coil will still shift laterally, affecting the cold bending effect. Furthermore, over long-term use, wear occurs at the contact points between the guide wheels and the coil, causing surface depressions and deteriorating the limiting and guiding effect. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a guide device for a cold bending forming machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a guide device for a cold bending forming machine, comprising a table, with support feet fixedly connected to the four corners of the lower surface of the table, a rectangular opening in the middle of the table, two symmetrical guide components slidably connected inside the rectangular opening, an adjusting component for driving the two guide components to move installed on the lower surface of the table, a gantry frame fixed on the upper surface of the table and located on one side of the rectangular opening, a pressing component inside the gantry frame, and a screw for driving the pressing component to rise and fall installed at the top of the gantry frame.

[0006] Furthermore, both of the guide components include C-shaped plates with their openings facing each other. The top walls of the C-shaped plates are provided with a plurality of perforations at equal intervals. A shaft is slidably inserted inside each perforation. A rotatable guide roller is sleeved on the surface of the shaft and is located inside the C-shaped plate.

[0007] Furthermore, the bottom surface of the shaft is provided with threads, the inner bottom wall of the C-shaped plate is provided with a threaded groove for screwing the shaft in, and a knob is fixedly connected to the top of the shaft.

[0008] Furthermore, the adjustment assembly includes a first U-shaped plate fixed to the lower surface of the platform, a guide rod fixed inside the first U-shaped plate, and two symmetrical movable seats slidably connected to the surface of the guide rod. The top ends of the two movable seats are respectively fixedly connected to the bottom ends of the two C-shaped plates.

[0009] Furthermore, a bidirectional lead screw is rotatably connected inside the first U-shaped plate via a bearing. The bidirectional lead screw passes through two movable seats and is threadedly connected to the two movable seats. One end of the bidirectional lead screw passes through the first U-shaped plate and is fixedly connected to a handwheel.

[0010] Furthermore, the pressing assembly includes a second U-shaped plate, a pressure roller is rotatably connected inside the second U-shaped plate, side rods are fixed on both sides of the second U-shaped plate, a sliding sleeve is fixedly connected to the other end of the side rod, the sliding sleeve is sleeved on the surface of the gantry frame and slidably connected to the gantry frame, the screw passes through the gantry frame and is threadedly connected to the gantry frame, and the bottom end of the screw is rotatably connected to the upper surface of the second U-shaped plate through a bearing.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a guide device for a cold bending forming machine is disclosed, comprising a table 1, with support feet 7 fixedly connected to the four corners of the lower surface of the table 1, a rectangular opening 101 in the middle of the table 1, two symmetrical guide components 2 slidably connected inside the rectangular opening 101, an adjustment component 3 for driving the two guide components 2 to move installed on the lower surface of the table 1, a gantry frame 4 fixed on the upper surface of the table 1 and located on one side of the rectangular opening 101, a pressing component 5 provided inside the gantry frame 4, and a screw 6 for driving the pressing component 5 to rise and fall installed at the top of the gantry frame 4.

[0023] Both guide components 2 include C-shaped plates 21 with their openings facing each other. The top wall of the C-shaped plates 21 has several perforations 22 at equal intervals. A shaft 23 is slidably inserted inside each perforation 22. A rotatable guide roller 24 is sleeved on the surface of the shaft 23 and is located inside the C-shaped plate 21.

[0024] When the roll passes through the two C-shaped plates 21, it can move between the two C-shaped plates 21. The side of the roll is in contact with the guide roller 24. During the movement of the roll, the guide roller 24 guides the roll and prevents the roll from shifting laterally.

[0025] The bottom surface of the shaft 23 is threaded, and the inner bottom wall of the C-shaped plate 21 is provided with a threaded groove 26 for screwing the shaft 23 in. A knob 25 is fixedly connected to the top of the shaft 23.

[0026] When the guide roller 24 needs to be replaced, the bottom end of the shaft 23 can be unscrewed from the threaded groove 26, and then the shaft 23 can be pulled out from the top through hole 22 to disassemble the guide roller 24. When installing the guide roller 24, place the guide roller 24 into the C-shaped plate 21, then pass the bottom end of the shaft 23 through the through hole 22 and the inside of the guide roller 24, and screw the shaft 23 into the bottom threaded groove 26.

[0027] The adjustment assembly 3 includes a first U-shaped plate 31 fixed to the lower surface of the platform 1. A guide rod 32 is fixed inside the first U-shaped plate 31. Two symmetrical movable seats 33 are slidably connected to the surface of the guide rod 32. The top ends of the two movable seats 33 are respectively fixedly connected to the bottom ends of the two C-shaped plates 21.

[0028] The movable seat 33 can move along the guide rod 32, and the movable seat 33 will drive the C-shaped plate 21 of the guide assembly 2 to move synchronously.

[0029] The first U-shaped plate 31 is rotatably connected to a bidirectional lead screw 34 via a bearing. The bidirectional lead screw 34 passes through two movable seats 33 and is threadedly connected to the two movable seats 33. One end of the bidirectional lead screw 34 passes through the first U-shaped plate 31 and is fixedly connected to a handwheel 35.

[0030] By rotating the double-acting screw 34 via the handwheel 35, the double-acting screw 34 will drive the two moving seats 33 to move closer or further apart, ultimately achieving the movement of the two C-shaped plates 21 closer or further apart.

[0031] The pressing assembly 5 includes a second U-shaped plate 51, a pressure roller 52 is rotatably connected inside the second U-shaped plate 51, side rods 53 are fixed on both sides of the second U-shaped plate 51, and a sliding sleeve 54 is fixedly connected to the other end of the side rod 53. The sliding sleeve 54 is sleeved on the surface of the gantry frame 4 and slidably connected to the gantry frame 4. The screw 6 passes through the gantry frame 4 and is threadedly connected to the gantry frame 4. The bottom end of the screw 6 is rotatably connected to the upper surface of the second U-shaped plate 51 through a bearing.

[0032] The second U-shaped plate 51 can move up and down along the gantry 4 via the sliding sleeve 54. After rotating the screw 6, the second U-shaped plate 51 can be moved, thereby driving the pressure roller 52 to press on the surface of the roll material.

[0033] Working principle: When guiding and limiting roll materials of different widths, the handwheel 35 can be rotated to drive the bidirectional lead screw 34 to rotate. The bidirectional lead screw 34 drives the two guide components 2 to move closer or further apart, so that the guide rollers 24 of the guide components 2 are in contact with both sides of the roll material. Then, by rotating the screw 6, the pressure roller 52 is driven to descend, and the pressure roller 52 presses against the surface of the roll material to limit the top of the roll material. When the roll material moves between the two guide components 2, it will not deviate laterally.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
