Description

Technical Field

[0001] The utility model belongs to the technical field of furniture production, and in particular relates to a tool for bending metal closing lines. Background Art

[0002] At present, in the field of furniture production, the edge trimming line (also known as the edge trimming strip) is a widely used edge trimming method for furniture panels. It has the advantages of being beautiful, durable, and not easy to fall off. In the process of furniture production, it is inevitable that some furniture countertops or panels have curvatures, which requires the edge trimming line to be bent along with the panel. In the prior art, the edge trimming line is often bent manually, but this method of bending the metal edge trimming line will mostly cause irregular deformation defects. Taking the U-shaped aluminum alloy edge trimming line as an example, the manual bending method will cause deformation defects such as warping of the narrow edge, depression of the wide edge, or uneven bending curvature, which will seriously affect the aesthetics of the furniture made using it.

[0019] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a folding tool for closing strip of the present utility model with reference to the accompanying drawings.

[0020] As Figures 1-3 shown, the folding tool for closing strip of the present utility model includes a mold roller 1, which corresponds to the closing strip. A pressing device 2 corresponding to it is arranged on one side of the mold roller 1. The two cooperate to work, and the corresponding surfaces of the two are the working surfaces of the two. The closing strip corresponding to the pressing device 2 is tightly pressed on the mold roller 1, and then bent into a corresponding arc. A clamping device 3 corresponding to it is arranged on the side of the corresponding working surfaces of the mold roller 1 and the pressing device 2. In this embodiment, the pressing device 2 is arranged on the right side of the mold roller 1, and the two cooperate to work in a left-right correspondence. The clamping device 3 is arranged at the rear of the corresponding working surfaces of the two. During work, the pressing device 2 rotates clockwise to bend the closing strip between it and the mold roller 1 into a corresponding arc. During this process, the clamping device 3 assists the pressing device 2 and the mold roller 1 to work. It clamps the closing strip to prevent the closing strip from sliding during the folding process and avoid deformation defects caused by its sliding. The above components are all arranged on the corresponding base 4. The folding tool can directly use the base 4 as a workbench, or it can also be externally connected to the corresponding bench through the base 4 for use.

[0021] The die roller 1 includes a die wheel body 11. The outer diameter dimension of the die wheel body 11 corresponds to the radius of the arc that the closing line needs to be bent. A corresponding die wheel shaft 12 is provided at the axis of the die wheel body 11, and the two are rotatably connected. The die wheel body 11 is fixedly installed on the base 4 through the die wheel shaft 12. In this embodiment, the die roller 1 is vertically arranged, and the base 4 is arranged below it. The lower end of the die wheel shaft 12 is fixedly connected to the base 4. An annular clamping groove 13 is provided on the outer side wall of the die wheel body 11. The clamping groove 13 corresponds to the narrow side of the closing line. The center of the clamping groove 13 is at the axis of the die wheel body 11. During use, the narrow side of the closing line is embedded in the clamping groove 13, and the clamping groove 13 clamps it. The wide side of the closing line is attached to the outer side wall of the die wheel body 11 under the action of the pressing device 2. Thus, as the pressing device 2 rotates, the closing line is bent into an arc with the same outer diameter as the die wheel body 11.

[0022] Furthermore, a plurality of clamping grooves 13 are provided on the outer side wall of the die wheel body 11. The size of the clamping groove 13 and the distance between adjacent clamping grooves 13 can be set as needed. Thus, the same die wheel body 11 can be used for the same-arc bending processing of various different models of closing lines. In this way, not only can the manufacturing cost of the die wheel body 11 be saved, but also when processing closing lines of the same arc and different models, there is no need to frequently replace the tooling, reducing the working hours and making the processing efficiency higher.

[0023] Furthermore, the die wheel body 11 is made of a nylon rod, and its material has a certain elasticity, which can play a better clamping role on the narrow side of the closing line.

[0024] The pressing device 2 includes a pressing roller 21 and a pressing mechanism 5. The pressing roller 21 is arranged on one side of the die roller 1, and its axis is parallel to the axis of the die roller 1. A corresponding pressing wheel shaft 22 is provided at its axis, and the two are rotatably connected. The pressing roller 21 is connected to the pressing mechanism 5 through the pressing wheel shaft 22. It can move left and right relative to the die wheel body 11 and can also rotate around the axis of the die roller 1 under the action of the pressing mechanism 5. During work, the pressing mechanism 5 adjusts the distance between its outer side wall and the outer side wall of the die wheel body 11 by controlling the left and right movement of the pressing roller 21, so that the pressing roller 21 presses the closing line entering the gap between it and the die wheel body 11 against the die wheel body 11. Then, by rotating the pressing roller 21 around the die wheel body 11, the closing line is bent into an arc with the same size as the outer diameter of the die wheel body 11.

[0025] The pressing mechanism 5 includes a fixed frame 51 and a pressing screw 52. The fixed frame 51 is arranged on one side of the die wheel body 11 corresponding to the pressing roller 21. The pressing device 2 is rotatably connected to the die wheel shaft 12 through the fixed frame 51. The pressing screw 52 is arranged on the fixed frame 51 on the opposite side of the pressing roller 21 and the die wheel body 11. Its axis is located on the extension line of the midline connection line of the die wheel shaft 12 and the pressing wheel shaft 22. A support frame 53 corresponding to the pressing roller 21 is arranged at the inner end of the pressing screw 52. The pressing roller 21 is installed on the support frame 53 through the pressing wheel shaft 22. The pressing screw 52 can drive the pressing roller 21 to move left and right through the support frame 53, thereby adjusting the distance between the pressing roller 21 and the die roller 1. In this embodiment, before the fixed frame 51 rotates, it is arranged on the right side of the die wheel body 11. It includes a pair of fixed rods 55 that are parallel to each other up and down. The right ends of the two fixed rods 55 are respectively rotatably connected to the upper and lower sides of the die wheel shaft 12. The left ends of the two fixed rods 55 are provided with corresponding fixed blocks 56. The upper and lower ends of the fixed block 56 are respectively fixedly connected to the corresponding fixed rods 55 on the corresponding side. The pressing screw 52 is arranged on the fixed block 56 of the fixed frame 51, and the two can be adjustably fixedly connected. In this embodiment, the two are threadedly connected. An external thread is arranged on the outer side wall of the pressing screw 52, and a threaded hole 57 corresponding to the pressing screw 52 is arranged in the middle of the fixed block 56. The inner end of the pressing screw 52 passes through the threaded hole 57 and is connected to the outer side wall of the support frame 53, and the two can be rotatably connected. The pressing screw 52 can adjust the length of its inner end extending into the fixed frame 51 by rotation, thereby driving the pressing roller 21 to move through the support frame 53 and adjusting the distance between it and the die roller 1. It can also be tightened through the threaded fit between it and the threaded hole 57, making itself not easy to loosen, so it is not easy to break away from the fixed frame 51, and can better provide a pressing force for the closing strip through the pressing roller 21. Again, through the pressing screw 52, it is more convenient to apply a rotational force to the fixed frame 51 and the pressing roller 21, so that the closing strip is bent along the outer side wall of the die wheel body 11.

[0026] Further, a pair of sliding grooves 58 corresponding to the pressing wheel shaft 22 are arranged on the two fixed rods 55. Both sliding grooves 58 are parallel to the connection line of the midlines of the die wheel shaft 12 and the pressing wheel shaft 22. The upper and lower ends of the pressing wheel shaft 22 are respectively inserted into the corresponding sliding grooves 58 on the upper and lower sides. When the pressing roller 21 moves left and right driven by the pressing screw 52, the sliding grooves 58 provide a guiding function for it.

[0027] Further, a corresponding handle 54 is arranged at the outer end of the pressing screw 52. The axis of the handle 54 is perpendicular to it. The pressing screw 52 can be rotated more conveniently and labor - savingly through the handle 54.

[0028] The clamping device 3 includes a fixed seat 31 which is arranged on one side of the corresponding working surfaces of the die roller 1 and the pressing device 2. In this embodiment, the fixed seat 31 is arranged at the rear side of the pressing device 2, at the position of the right rear side of the die wheel body 11. Its left side surface faces the working surface of the pressing device 2 and serves as the fixing surface for the closing strip. A corresponding clamp 32 is arranged on the left side surface of the fixed seat 31. When the pressing device 2 rotates and bends the closing strip relative to the die roller 1, the clamp 32 clamps the corresponding side of the closing strip to prevent it from sliding during the bending process. A pair of mounting holes 33 are arranged on the fixed seat 31, and a pair of mounting grooves 41 corresponding to the mounting holes 33 are arranged on the base 4. The two mounting grooves 41 are parallel and corresponding. The fixed seat 31 can be fixed at different positions of the mounting grooves 41 through corresponding bolts according to different die wheel bodies 11. During use, after determining the position of the fixed seat 31, pass the corresponding bolts through the mounting holes 33 and the mounting grooves 41 in sequence, and then use the corresponding nuts to cooperate with the bolts and tighten them, then the fixed seat 31 can be fixed at the determined position. When its position needs to be adjusted, loosen the nut, and then repeat the above steps again.

[0029] During use, first select a suitable die wheel body 11 according to the specifications of the closing strip and the radian it needs to be bent, install it on the bending tooling, and then rotate the pressing screw 52 to adjust the distance between the pressing roller 21 and the die wheel body 11, so that the corresponding closing strip is pressed against the die roller 1. At this time, the narrow side of the closing strip is embedded in the clamping groove 13, and the clamping groove 13 clamps it. The wide side of the closing strip fits against the outer side wall of the die wheel body 11 under the action of the pressing device 2. Then, adjust the position of the fixed seat 31 and the die wheel body 11 and fix them at the corresponding positions. Clamp and fix the corresponding side of the closing strip through the clamp 32. At this time, apply a rotational force to the fixed frame 51 and the pressing roller 21 through the pressing screw 52. The fixed frame 51 rotates around the die wheel shaft 12 to provide a guiding effect for the pressing roller 21. The pressing roller 21 rotates around the outer side wall of the die wheel body 11, and presses the closing strip tightly against the outer side wall of the die wheel body 11, so that the closing strip is bent into the corresponding radian along the outer side wall of the die wheel body 11.

[0030] The clamping of the narrow side of the closing strip by the clamping groove 13 of the closing strip bending tooling of the present utility model makes it not easy to deform during bending. The pressing device 2 makes the wide side of the closing strip closely adhere to the outer side of the die wheel body 11 during bending. The two cooperate with each other to greatly reduce the probability of deformation defects. The closing strip bending tooling of the present utility model makes the closing strip bend in a uniform radian. Compared with the traditional manual operation, the bent closing strip is more uniform and beautiful, improving the aesthetics of the furniture made of the closing strip bent by it. Its structure is simple, the operation is convenient, and it is easy to operate.
