Description

Technical Field

[0001] This utility model relates to the field of rolling die technology, and in particular to an adjustable rolling die. Background Technology

[0002] In metal processing, plastic molding, and other fields, roll forming dies are widely used in forming, embossing, or leveling processes for sheet metal, pipes, or other profiles. Traditional roll forming dies typically employ a fixed-gap rotating roller structure, with its working width and pressure being non-adjustable. This necessitates frequent die changes or equipment adjustments when dealing with workpieces of different sizes or thicknesses, which not only increases operational complexity but also reduces production efficiency, especially in small-batch, multi-variety production scenarios. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where traditional rolling dies typically employ a fixed-gap rotating roller structure, whose working width and pressure are not adjustable. This results in the need for frequent die replacements or equipment adjustments when dealing with workpieces of different sizes or thicknesses, which not only increases operational complexity but also reduces production efficiency. The invention provides an adjustable rolling die.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable rolling die, including a base, a groove formed on the outer surface of the base, a motor sleeved on the inner wall of the groove, the motor being placed inside the base, a bidirectional lead screw fixedly connected to one end of the motor, a moving rod sleeved on the outer surface of the bidirectional lead screw, a connecting rod fixedly connected to the outer surface of the moving rod, a bearing fixedly connected to one end of the bidirectional lead screw, the bearing being placed inside the base, a second rotating roller sleeved on the outer surface of the connecting rod, two second rotating rollers being provided in total, and a collar sleeved on the outer surface of the connecting rod.

[0005] In a preferred embodiment, a support frame is fixedly connected to the outer surface of the base, a hydraulic pump is fixedly connected to the outer surface of the support frame, a telescopic rod is fixedly connected to one end of the hydraulic pump, and a first rotating roller is sleeved on one end of the telescopic rod. Two first rotating rollers are provided.

[0006] In a preferred embodiment, a fixing frame is fixedly connected to the outer surface of the base, a fixing rod is fixedly connected to one end of the fixing frame, and a first rotating rod is sleeved on the outer surface of the fixing rod, with the first rotating rod rotatably connected to the fixing rod.

[0007] In a preferred embodiment, the inner wall of the collar is threaded to the outer surface of the connecting rod.

[0008] In a preferred embodiment, the inner wall of the second rotating roller is rotatably connected to the outer surface of the connecting rod.

[0009] In a preferred embodiment, the outer surface of the movable rod is provided with a screw hole, which is threadedly connected to a bidirectional lead screw.

[0010] In a preferred embodiment, the bearing is fixedly connected to the inner wall of the base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention provides a good working environment for other components through the base, limits the movement of the moving rod through the slide groove to ensure that the moving rod does not rotate, and drives the bidirectional lead screw to rotate inside the bearing through the motor. Since the bidirectional lead screw is threadedly connected to the screw hole, the rotation of the bidirectional lead screw drives the two moving rods to move in opposite directions, thereby adjusting the distance of the second rotating roller, which makes it convenient for workers to roll molds of different specifications. The connecting rod is threadedly connected to the collar to ensure that the second rotating roller will not fall off. The rotational connection between the second rotating roller and the connecting rod ensures that the rolling operation is normal. Attached Figure Description

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: an adjustable rolling die, including a base 1, a groove 11 on the outer surface of the base 1, a motor 13 sleeved on the inner wall of the groove 11, the motor 13 being placed inside the base 1, a bidirectional lead screw 14 fixedly connected to one end of the motor 13, a moving rod 6 sleeved on the outer surface of the bidirectional lead screw 14, a screw hole 15 on the outer surface of the moving rod 6, the screw hole 15 being threadedly connected to the bidirectional lead screw 14, a connecting rod 16 fixedly connected to the outer surface of the moving rod 6, a bearing 12 fixedly connected to one end of the bidirectional lead screw 14, the bearing 12 being placed inside the base 1, a second rotating roller 10 sleeved on the outer surface of the connecting rod 16, two second rotating rollers 10 being provided in total, and a collar 9 sleeved on the outer surface of the connecting rod 16.

[0022] In this embodiment, the base 1 provides a good working environment for other components. The slide groove 11 limits the movement of the moving rod 6 to prevent it from rotating. The motor 13 drives the bidirectional lead screw 14 to rotate inside the bearing 12. Since the bidirectional lead screw 14 is threadedly connected to the screw hole 15, the rotation of the bidirectional lead screw 14 drives the two moving rods 6 to move in opposite directions, thereby adjusting the distance of the second rotating roller 10. This allows the operator to roll molds of different specifications. The connecting rod 16 is threadedly connected to the collar 9 to ensure that the second rotating roller 10 will not fall off. The rotational connection between the second rotating roller 10 and the connecting rod 16 ensures that the rolling operation is carried out normally.

[0023] Example 2

[0024] like Figures 1-4 As shown, a support frame 2 is fixedly connected to the outer surface of the base 1, a hydraulic pump 3 is fixedly connected to the outer surface of the support frame 2, a telescopic rod 4 is fixedly connected to one end of the hydraulic pump 3, a first rotating roller 5 is sleeved on one end of the telescopic rod 4, and two first rotating rollers 5 are provided. A fixing frame 7 is fixedly connected to the outer surface of the base 1, a fixing rod 8 is fixedly connected to one end of the fixing frame 7, and the first rotating roller 5 is sleeved on the outer surface of the fixing rod 8. The first rotating roller 5 is rotatably connected to the fixing rod 8.

[0025] In this embodiment, the hydraulic pump 3 is fixed by the support frame 2 to provide an installation environment. The hydraulic pump 3 drives the telescopic rod 4 to move. The movement of the telescopic rod 4 drives the first rotating roller 5 to adjust its height, thereby performing rolling work on the rolling die of different specifications. The fixing frame 7 provides a working environment for the first rotating roller 5. The fixing rod 8 ensures that the first rotating roller 5 will not fall. The fixing rod 8 is rotatably connected to the first rotating roller 5 to ensure that the rolling work is carried out normally.

[0026] Working principle:

[0027] like Figures 1-4 As shown, in this utility model, during rolling, the operator adjusts the mold according to its specifications. The motor 13 drives the bidirectional lead screw 14 to rotate inside the bearing 12. Since the bidirectional lead screw 14 is threadedly connected to the screw hole 15, the rotation of the bidirectional lead screw 14 drives the two moving rods 6 to move in opposite directions, thereby adjusting the distance of the second rotating roller 10. Then, the connecting rod 16 is threadedly connected to the collar 9 to ensure that the second rotating roller 10 will not fall off. Then, the hydraulic pump 3 drives the telescopic rod 4 to move. The movement of the telescopic rod 4 drives the first rotating roller 5 to adjust its height. The fixing frame 7 provides a working environment for the first rotating roller 5. The fixing rod 8 ensures that the first rotating roller 5 will not fall off. The second rotating roller 10 is rotatably connected to the connecting rod 16 and the first rotating roller 5 is rotatably connected to the fixing rod 8, so that the mold can be rolled and formed normally during the rolling operation.
