Description

Technical Field

[0001] This utility model relates to the field of bending die technology, specifically to stamping bending dies. Background Technology

[0002] A bending die is a tool used to assist in bending and shaping sheet metal. It mainly changes the physical state of the material (mainly metal sheet) by applying bending pressure, thereby changing the material's shape to obtain the desired shape.

[0003] In practical use, bending dies often need to be replaced due to changes in sheet metal dimensions to accommodate bending of different sizes. However, the disassembly and assembly of bending dies is cumbersome, mostly involving vertical disassembly, which is inconvenient for quick replacement. Furthermore, some stamping bending machines have poor applicability and are not suitable for bending dies of different sizes, resulting in low efficiency in sheet metal bending. Therefore, we propose stamping bending dies to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a stamping and bending die to solve the problems mentioned in the background art, such as the poor applicability of some current stamping and bending machines to bending dies and the inconvenience of disassembling and assembling bending dies.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping and bending die, comprising a supporting body, on which a hydraulic cylinder is mounted, and a lower stamping seat is fixed at the output end of the hydraulic cylinder. The lower stamping seat is located on the upper side of the supporting body, and a stabilizing rod is fixed on the lower side of the lower stamping seat. The stabilizing rod is connected through the supporting body. A bending die is mounted on the outer side of the lower stamping seat via a fixing bolt. Limiting seats are provided on both sides of the lower stamping seat, and the limiting seats are fixed on the supporting body. A meshing rack and gear are provided inside the limiting seats, and a rotating rod is fixed on the gear. A bending assembly for bending sheet metal is mounted on the rotating rod. A supporting frame is fixed on the supporting body, and a second hydraulic cylinder is mounted on the supporting frame. An upper stamping seat is fixed at the output end of the second hydraulic cylinder. The upper stamping seat and the lower stamping seat are vertically aligned. A second stabilizing rod is fixed on the upper side of the upper stamping seat and is connected through the supporting frame.

[0006] Preferably, the bending die is semi-cylindrical in shape, and the upper side of the stamping lower seat is tangent to the outer side of the bending die. The bending die and the stamping lower seat are detachably connected by fixing bolts.

[0007] Preferably, the lower end of the rack is fixedly connected to the output end of the hydraulic cylinder three, the hydraulic cylinder three is mounted on the support body, and the rack forms an up-and-down moving structure within the limiting seat through the hydraulic cylinder three.

[0008] Preferably, the gear is connected to the limiting seat via a bearing, and the gear moves up and down via the rack to form a rotating structure within the limiting seat. The rotation angle of the gear is limited to 0-180° by the rotating rod.

[0009] Preferably, the connection position between the central axis of the gear and the lower stamping seat and the bending die is located on the same vertical plane, and the central axis of the gear and the central axis of the bending die are the same straight line.

[0010] Preferably, the bending assembly includes a bending rod, a limiting link, and a nut. The bending rod is movably sleeved on the limiting link, and the two ends of the limiting link are threaded with nuts. The two ends of the limiting link are fixedly connected to the rotating rod by the nuts.

[0011] Preferably, the rotating rod has a through-hole structure in the middle, and the position of the limiting link on the rotating rod can be changed up and down.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

At the same time, there are rotating rods on both sides of the stamping lower seat, and bending rods are provided between the rotating rods. This enables the sheet metal to be bent by fitting the bending die under the extrusion of the bending rods.

[0014] (2) The lower stamping seat can be moved up and down by a hydraulic cylinder, so that the center of the bending die of different sizes is aligned with the rotation center of the rotating rod, thus ensuring the normal operation of the bending work.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-7 The present invention provides a technical solution: a stamping and bending die, including a support body 1, a hydraulic cylinder 2 installed on the support body 1, a stamping lower seat 4 fixed on the output end of the hydraulic cylinder 2, the stamping lower seat 4 being located on the upper side of the support body 1, and a stabilizing rod 3 fixed on the lower side of the stamping lower seat 4, the stabilizing rod 3 being connected through the support body 1, which enables the stamping lower seat 4 to move up and down stably.

[0025] A bending die 5 is installed on the outer side of the stamping lower seat 4 via a fixing bolt 15.

[0026] Furthermore, the bending die 5 is semi-cylindrical in shape, and the upper side of the stamping lower seat 4 is tangent to the outer side of the bending die 5, ensuring that the sheet metal is stably bent while adhering to the stamping lower seat 4 and the bending die 5. The bending die 5 and the stamping lower seat 4 are detachably connected by a fixing bolt 15, which facilitates the disassembly and replacement of the bending die 5.

[0027] The lower stamping seat 4 is provided with limit seats 6 on both sides. The limit seats 6 are fixed on the support body 1. The limit seats 6 are provided with meshing racks 7 and gears 8. A rotating rod 9 is fixed on the gear 8. A bending component for bending sheet metal is installed on the rotating rod 9.

[0028] Furthermore, the lower end of the rack 7 is fixedly connected to the output end of the hydraulic cylinder 3 18, which is mounted on the support body 1. The rack 7 forms an up-and-down moving structure within the limit seat 6 via the hydraulic cylinder 3 18. The gear 8 is connected to the limit seat 6 via a bearing. The gear 8 moves up and down via the rack 7, forming a rotating structure within the limit seat 6. The rotation angle of the gear 8 is limited to 0-180° by the rotating rod 9, and the rotation of the rotating rod 9 can be controlled by the rack 7.

[0029] Furthermore, the connection between the central axis of gear 8 and the lower stamping seat 4 and the bending die 5 is located on the same vertical plane, and the central axis of gear 8 and the central axis of bending die 5 are on the same straight line. By moving the lower stamping seat 4 up and down, the center of bending die 5 can be aligned with the center of gear 8, thus ensuring that bending rod 10 rotates stably outside bending die 5, thereby achieving normal bending work.

[0030] A support frame 11 is fixed on the support body 1. A hydraulic cylinder 12 is installed on the support frame 11. A stamping upper seat 14 is fixed on the output end of the hydraulic cylinder 12. The stamping upper seat 14 and the stamping lower seat 4 are aligned vertically. A stabilizing rod 13 is fixed on the upper side of the stamping upper seat 14. The stabilizing rod 13 is connected through the support frame 11 to ensure the stable vertical displacement of the stamping upper seat 14, thereby cooperating with the stamping lower seat 4 to achieve stable extrusion and fixing of the sheet metal.

[0031] Furthermore, the bending assembly includes a bending rod 10, a limiting link 16, and a nut 17. The bending rod 10 is movably sleeved on the limiting link 16, ensuring that the bending rod 10 can move freely on the limiting link 16, which facilitates the rotational bending operation. Nuts 17 are threaded to both ends of the limiting link 16, and the two ends of the limiting link 16 are fixedly connected to the rotating rod 9 through the nuts 17. This facilitates the disassembly and assembly of the limiting link 16 and ensures that the limiting link 16 is stable in its working state on the rotating rod 9.

[0032] Furthermore, the rotating rod 9 has a through-hole structure in the middle, and the position of the limiting link 16 on the rotating rod 9 can be changed up and down, so that the limiting link 16 can be used with plates of different thicknesses and bending dies 5 of different sizes to perform bending work, thereby increasing the applicability of the bending die.

[0033] Specifically, when using this stamping and bending die, the bending die 5 is first installed on the side of the lower stamping seat 4 by the fixing bolt 15. Then, by the extension and retraction of the hydraulic cylinder 2 and the action of the stabilizer rod 3, the lower stamping seat 4 moves stably up and down on the support body 1. Through the up and down movement of the lower stamping seat 4, the center of the bending die 5 is aligned with the center of the gear 8, ensuring the normal rotation and bending operation of the bending rod 10.

[0034] Then, place the sheet metal to be bent onto the lower stamping seat 4, and adjust the position of the bending rod 10 so that the bending rod 10 can contact the upper side of the sheet metal. Lock the connection between the rotating rod 9 and the limiting link 16 with the nut 17 to ensure the stable working state of the bending rod 10.

[0035] Then, by extending and retracting the hydraulic cylinder 12, the upper stamping seat 14 is moved down stably on the support frame 11 via the stabilizer bar 13, and the upper stamping seat 14 can cooperate with the lower stamping seat 4 to squeeze and clamp the sheet metal.

[0036] Then, by extending and retracting the hydraulic cylinder 18, the rack 7 moves upward within the limit seat 6, and the gear 8, which meshes with the rack 7, rotates. Through the rotating rod 9, the bending rod 10 rotates around the outside of the bending mold 5. During the rotation of the bending rod 10, it can press the plate against the outside of the bending mold 5, thereby achieving the bending and forming of the plate.

[0037] Finally, the upper stamping seat 14 is moved upward to end the extrusion and fixing of the sheet metal. The bent sheet metal can then be pulled out directly from the outside of the bending die 5, thus completing the working process of the stamping and bending die. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
