Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending device technology, and in particular to a sheet metal bending device. Background Technology

[0002] A mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by changing the physical state of the material being shaped. Bending is frequently involved in sheet metal processing, hence the development of various bending dies to meet production standards.

[0003] Most existing bending dies require the use of a punch press, which not only makes the die structure complex, but also causes metal debris generated by the deformation of the sheet metal parts during the bending process to remain inside the die, affecting the accuracy of subsequent sheet metal processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where residues in sheet metal forming molds affect processing accuracy, and to propose a sheet metal bending device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a sheet metal bending device, including a base, with sliding bases fixed to both sides of the base, a slide rail slidably fitted on the sliding base, an incomplete mold fixed to the slide rail, an electric cylinder fixed to the base, a connecting plate fixed to the output end of the electric cylinder, a punch head fixed to the connecting plate, and a driving structure on the base to drive the slide rail to move on the sliding base.

[0007] Preferably, the drive structure includes a rotating shaft rotatably mounted on a base, a drive gear fixedly connected to the rotating shaft, a driven gear rotatably mounted on the sliding base, the drive gear and the driven gear being matched, and a second rack fixedly connected to the bottom of the incomplete mold, the driven gear being matched with the second rack.

[0008] Preferably, the connecting plate is provided with a rotating structure to drive the rotating shaft to rotate. The rotating structure includes a bearing seat, which is fixedly connected to the base. A worm gear is rotatably installed inside the bearing seat. A worm wheel is fixedly connected to the rotating shaft. The worm gear and the worm wheel are matched. A first rack is fixedly connected to both sides of the connecting plate. A transmission gear is fixedly connected to the worm gear along the same axis. The first rack is matched with the transmission gear.

[0009] Preferably, the distance between the two sliding bases is not less than the length of the stamping head.

[0010] Preferably, the shape of the stamping head matches the internal structure of the two incomplete molds.

[0011] The sheet metal bending device proposed in this utility model has the following advantages: When bending sheet metal parts, the sheet metal parts are placed between two incomplete molds. Then, the electric cylinder is activated, and the electric cylinder drives the punch head to apply pressure to the sheet metal parts through the connecting plate. During the application of pressure, the two incomplete molds connect together to form a complete mold. Under the pressure of the punch head, the sheet metal parts are bent to the required angle within the complete mold. After the sheet metal parts are bent, the punch head moves up and resets, and the two incomplete molds move away from each other. During this process, under the action of gravity, the bent sheet metal parts fall between the two incomplete molds, thus completing the blanking process. Furthermore, the debris generated during the bending process is also cleaned out of the two incomplete molds under the action of gravity, preventing residual debris from affecting the shape of subsequent bending processes.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-2A sheet metal bending device includes a base 1, with sliding bases 2 fixedly connected to both sides of the base 1. A slide rail 4 is slidably fitted on the sliding base 2, and an incomplete mold 3 is fixedly connected to the slide rail 4. The distance between the two sliding bases 2 is not less than the length of the punch head 5. An electric cylinder 6 is fixedly connected to the base 1, and a connecting plate 7 is fixedly connected to the output end of the electric cylinder 6. A punch head 5 is fixedly connected to the connecting plate 7. The shape of the punch head 5 matches the internal structure of the two incomplete molds 3. A driving structure is provided on the base 1 to drive the slide rail 4 to move on the sliding base 2.

[0019] When bending sheet metal parts, the sheet metal part is placed between two incomplete molds 3. Then, the electric cylinder 6 is activated, which drives the punch head 5 through the connecting plate 7 to apply pressure to the sheet metal part. During the application of pressure, the two incomplete molds 3 connect to form a complete mold. Under the pressure of the punch head 5, the sheet metal part is bent to the required angle within the complete mold. After the sheet metal part is bent, the punch head 5 moves upward and resets, and the two incomplete molds 3 move away from each other. During this process, under the action of gravity, the bent sheet metal part falls between the two incomplete molds 3, thus completing the blanking process. Furthermore, the debris generated during the bending process is also cleaned out of the two incomplete molds 3 under the action of gravity to prevent residual debris from affecting the shape of subsequent bending processes.

[0020] like Figure 3-4 As shown, a rotating shaft 12 is rotatably mounted on the base 1, a bearing seat 11 is fixedly connected to the base 1, a worm gear 10 is rotatably mounted inside the bearing seat 11, a worm wheel 13 is fixedly connected to the rotating shaft 12, the worm gear 10 and the worm wheel 13 are matched, a first rack 8 is fixedly connected to both sides of the connecting plate 7, a transmission gear 9 is coaxially fixed to the worm gear 10, the first rack 8 and the transmission gear 9 are matched, a driving gear 16 is fixedly connected to the rotating shaft 12, a driven gear 14 is rotatably mounted on the sliding base 2, the driving gear 16 and the driven gear 14 are matched, a second rack 15 is fixedly connected to the bottom of the incomplete mold 3, the driven gear 14 and the second rack 15 are matched.

[0021] During the movement of the connecting plate 7 driven by the electric cylinder 6, the first rack 8 on the connecting plate 7 drives the transmission gear 9 to rotate. The rotation of the transmission gear 9 drives the worm 10 to rotate, the rotation of the worm 10 drives the worm wheel 13 to rotate, the rotation of the worm wheel 13 drives the rotating shaft 12 to rotate, the rotation of the rotating shaft 12 drives the driving gear 16 to rotate, the rotation of the driving gear 16 drives the driven gear 14 to rotate, the rotation of the driven gear 14 drives the second rack 15 to move, and the movement of the second rack 15 will cause the incomplete mold 3 to slide on the sliding base 2, thereby controlling the opening and closing of the two incomplete molds 3.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
