Description

Technical Field

[0001] This utility model proposes a mold, which relates to the field of metal plate bending mold technology, and specifically to a quick-release structure for bending mold. Background Technology

[0002] Bending metal sheets is one of the main methods for making integrated cabinets. A whole metal sheet is bent at the required angle according to the required size, and then the two ends of the sheet are connected by welding and riveting to obtain a cabinet with good sealing effect.

[0003] Existing technology uses three adjustable rollers to bend sheet metal into an arc shape by applying pressure through a hydraulic system. This makes the metal sheet gradually bend into an arc shape as it rolls continuously. This bending process is complex and inefficient. However, this three-roller structure is troublesome to operate when changing the mold, and a large amount of the structure needs to be removed before the top roller can be replaced.

[0004] Based on the difficulties of existing technologies, those skilled in the art have proposed a quick-release structure for bending dies, which enables the rapid assembly and disassembly of the top roller. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick-release structure for bending dies. The top roller of the existing integrated structure is divided into two parts: the top roller and the mounting base plate. The two parts are fixed together by connecting screws. When changing the die, only the top roller needs to be removed for replacement, without disassembling the base plate, thus avoiding the trouble of removing the associated base plate mounting structure.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-release structure for a bending die, including a top roller. The top roller is a circular roller structure in a three-roller structure used to hold the inner side of the plate for bending. It is usually directly fixed to the equipment. When changing the die, many parts need to be removed before the top roller can be replaced.

[0007] This installation method ensures that the top roller is stably installed inside the equipment, but it is not conducive to changing the mold. Therefore, those skilled in the art have proposed an improvement scheme.

[0008] A connecting screw is fixed to the side of the top roller. The connecting screw is integrally welded to the top roller, and at least two connecting screws are provided on the side of the top roller to ensure stable installation.

[0009] The top roller is fixed to the base plate by a connecting screw. The top roller is installed in the bending equipment through the base plate. The base plate does not need to be removed when changing the mold. It is only necessary to release the limiting position between the connecting screw and the base plate and replace the corresponding top roller.

[0010] The existing integrated top roller and associated mounting structure are separated into a separate top roller and base plate. When changing the mold, only the top roller needs to be replaced without removing the base plate. This ensures the stable installation of the base plate and the bending equipment, and also facilitates quick mold disassembly.

[0011] Preferably, the side of the substrate has a mounting groove corresponding to the connecting screw, and the connecting screw fixes the top roller to the top of the substrate through the mounting groove.

[0012] The mounting groove corresponds to the diameter of the connecting screw, allowing the top roller with the connecting screw to be easily pushed into the mounting groove from one side for installation.

[0013] Preferably, a fastening nut is threaded onto the side of one end of the connecting screw that extends into the mounting groove. The fastening nut tensions the connection between the top roller and the base plate, ensuring stable installation and preventing the top roller from detaching from the mounting groove when subjected to thrust.

[0014] Preferably, a V-shaped groove is provided on the top of the substrate, and the top roller is tightened and clamped to the top of the substrate through the V-shaped groove. The V-shaped groove has a limiting effect on the top roller under the tension of the fastening nut.

[0015] This utility model discloses a quick-release structure for bending dies, which has the following beneficial effects:

[0016] This quick-release bending die structure separates the existing integrated top roller and base plate into two separate parts. The base plate is fixed to the bending equipment to ensure the stability of the top roller during the bending process. When changing the bending die, it is not necessary to remove the base plate. Simply release the limit between the base plate and the top roller to replace the top roller, thus avoiding the trouble of disassembling a large number of structures required for base plate assembly and disassembly.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model discloses a quick-release structure for a bending die;

[0024] According to the appendix Figure 1-3 As shown, it includes a top roller 1, which is a round roller structure in a three-roller structure used to press against the inner side of the plate for bending. It is usually directly fixed to the equipment. When changing the mold, many parts need to be removed before the top roller 1 can be replaced.

[0025] This installation method ensures that the top roller 1 is stably installed in the equipment, but it is not conducive to changing the mold. Therefore, those skilled in the art have proposed an improvement plan.

[0026] A connecting screw 2 is fixed to the side of the top roller 1. The connecting screw 2 is integrally welded to the top roller 1, and at least two connecting screws 2 are provided on the side of the top roller 1 to ensure stable installation.

[0027] The top roller 1 is fixed to the base plate 3 by the connecting screw 2. The top roller 1 is installed in the bending equipment through the base plate 3. The base plate 3 does not need to be removed when changing the mold. Just release the limit between the connecting screw 2 and the base plate 3 and replace the corresponding top roller 1.

[0028] The existing integrated top roller 1 and associated mounting structure are separated into a separate top roller 1 and a base plate 3. When changing the mold, only the top roller 1 needs to be replaced without removing the base plate 3. This ensures the stable installation of the base plate 3 with the bending equipment and also facilitates quick mold disassembly.

[0029] The side of the substrate 3 has a mounting groove 4 corresponding to the connecting screw 2. The connecting screw 2 fixes the top roller 1 to the top of the substrate 3 through the mounting groove 4.

[0030] One side of the mounting groove 4 does not penetrate the substrate 3. When the top roller 1 is installed on the top of the substrate 3 through the connecting screw 2, the part of the mounting groove 4 that does not penetrate has a unilateral limiting effect on the connecting screw 2. This not only ensures that the top roller 1 is installed in place on the top of the substrate 3, but also prevents the top roller 1 from being damaged by force.

[0031] The mounting groove 4 corresponds to the diameter of the connecting screw 2, which allows the top roller 1 with the connecting screw 2 to be easily pushed into the mounting groove 4 from one side for installation. The structure of the mounting groove 4 also facilitates the limiting of the tightness of the connecting screw 2, tightening the installation of the top roller 1 at the end of the base plate 3.

[0032] The connecting screw 2 extends into the mounting groove 4 and has a fastening nut 5 threaded on one side. The fastening nut 5 tensions the connection between the top roller 1 and the base plate 3, ensuring stable installation and preventing the top roller 1 from detaching from the mounting groove 4 when subjected to thrust.

[0033] A V-groove 6 is provided on the top of the substrate 3. The top roller 1 is tightened and clamped to the top of the substrate 3 through the V-groove 6. The V-groove 6 has a limiting effect on the top roller 1 under the tension of the fastening nut 5.

[0034] Furthermore, as a second embodiment, different mounting methods are provided for the top roller 1 and the base plate 3. The inner wall of the mounting groove 4 near the top roller 1 can also be provided with a groove with a diameter larger than that of the connecting screw 2. A limiting cylinder is fitted into the groove, and the limiting cylinder slides and engages with the groove. Then, the connecting screw 2 on the side of the top roller 1 is inserted into it, which can help limit the connecting screw 2.

[0035] The quick-release structure of the bending die separates the existing integrated top roller 1 and base plate 3 into two separate parts. The base plate 3 is fixed to the bending equipment to ensure the stability of the top roller 1 during the bending process. When changing the bending die, it is not necessary to remove the base plate 3. Simply release the limit between the base plate 3 and the top roller 1 to replace the top roller 1, thus avoiding the trouble of disassembling a large number of structures required for the disassembly and assembly of the base plate 3.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
