Description

Technical Field

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

[0002] Sheet metal parts are widely used in various industries. Among them, sheet metal parts with rounded corners can not only improve the aesthetics of products, but also improve safety compared to right-angle sheet metal parts in actual use.

[0003] A search revealed that utility model patent CN221133657U discloses a sheet metal bending arc corner flipping mold, comprising a device body, which includes a base, a bending mold, sheet metal, and a stamping mold. The base has an installation groove on its top, the bending mold is installed inside the base, the sheet metal is placed inside the bending mold, and the stamping mold is located above the sheet metal. The bending mold includes a first bending block and a second bending block, which are symmetrically distributed. When the first bending block and the second bending block are joined together, they form a U-shaped structure. A set of guide rods symmetrically distributed on the outer side of both the first bending block and the second bending block are provided.

[0004] Although the aforementioned sheet metal bending arc corner flipping mold can prevent U-shaped sheet metal parts from getting stuck between the first and second bending blocks, after bending, the bent sheet metal parts still need to be manually removed before they can be placed again, which has a certain impact on sheet metal bending efficiency.

[0005] Therefore, it is necessary to invent a sheet metal bending arc corner flipping mold to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a sheet metal bending arc corner flipping mold, which can push out the sheet metal part after stamping without manual removal, saving manpower and effectively improving the bending efficiency of sheet metal parts. This solves the problem mentioned in the background art that after bending, the bent sheet metal part still needs to be manually removed before it can be placed again, which has a certain impact on the bending efficiency of sheet metal.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a sheet metal bending arc corner flipping die, comprising:

[0008] The base is used to install and fix the bending mechanism and the discharge mechanism;

[0009] The bending mechanism includes two symmetrically arranged bending mechanisms, which are used to bend sheet metal parts; and...

[0010] The discharge mechanism includes two side plates, each located between two sets of bending mechanisms. The two side plates are symmetrically arranged. The top of the side plates closest to each other has an outer receiving groove. The inner side walls of the outer receiving groove have inner receiving grooves. A discharge push rod is movably arranged inside the outer receiving groove. A rotating shaft is fixedly installed at the end of the discharge push rod. The rotating shaft passes through the two side plates and is rotatably connected to the two side plates through bearings. Torsion springs are sleeved at both ends of the outer side of the rotating shaft. The torsion springs are located inside the adjacent inner receiving grooves and are fixedly connected between the inner wall of the inner receiving groove and the discharge push rod.

[0011] According to at least one embodiment of the sheet metal bending arc angle flipping mold of the present disclosure, the bending mechanism includes a bending block and a return spring. The bending block is rotatably connected to the base via a hinge, and the return spring is fixedly connected between the bending block and the inner wall of the base.

[0012] According to at least one embodiment of the sheet metal bending arc angle flipping mold of the present disclosure, the discharge mechanism further includes fixing bolts, the two side plates are detachably connected by fixing bolts, and any one of the side plates is fixedly connected to the inner wall of the base.

[0013] According to at least one embodiment of the sheet metal bending arc angle flipping mold of the present disclosure, threaded holes are provided on both side plates, and the fixing bolts are threadedly connected to the inside of the threaded holes.

[0014] A sheet metal bending arc angle flipping die according to at least one embodiment of the present disclosure further includes a stamping die for stamping the sheet metal part, the stamping die being located directly above the base.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a discharge mechanism that allows the return spring to rotate the bending block outward around the hinge after stamping, preventing the stamped U-shaped sheet metal from getting stuck. Meanwhile, the discharge push rod, driven by the torsion spring, rotates and resets around the rotation axis as it enters the outer receiving groove during the stamping process. During this process, one end of the U-shaped sheet metal is lifted upward by the discharge push rod, and then the U-shaped sheet metal slides out between the two bending mechanisms. Compared to existing technologies, this invention allows the sheet metal to be pushed out after stamping without manual removal, saving manpower and effectively improving the bending efficiency of the sheet metal.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of a sheet metal bending arc corner flipping mold according to one embodiment of the present disclosure.

[0028] Figure 2This is a schematic diagram of the bending mechanism 2 of a sheet metal bending arc angle flipping die according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the material discharge mechanism 3 of a sheet metal bending arc angle flipping die according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the sheet metal bending arc corner flipping mold disclosed herein may include components such as: base 1, bending mechanism 2, discharge mechanism 3, and stamping mold 4.

[0031] like Figure 2 As shown in this disclosure, the bending mechanism 2 includes a bending block 21 and a return spring 22. The bending block 21 is rotatably connected to the base 1 via a hinge, and the return spring 22 is fixedly connected between the bending block 21 and the inner wall of the base 1.

[0032] Therefore, when the stamping die 4 moves down to stamp the sheet metal part, the stamping die 4 pushes the inner wall of the bending block 21 through the sheet metal part, thereby causing the two bending blocks 21 to rotate towards each other, so as to cooperate with the discharge mechanism 3 to form a bending groove, so that the sheet metal part is bent into a U shape.

[0033] like Figure 3 As shown, in a preferred embodiment, the discharge mechanism 3 includes two side plates 31, each located between two sets of bending mechanisms 2. The two side plates 31 are symmetrically arranged. The top of the two side plates 31, which are close to each other, is provided with an outer receiving groove 32. The inner side walls of the outer receiving groove 32 are provided with inner receiving grooves 33. A discharge push rod 34 is movably arranged inside the outer receiving groove 32. A rotating shaft 35 is fixedly inserted through the end of the discharge push rod 34. The rotating shaft 35 passes through the two side plates 31 and is rotatably connected to the two side plates 31 through bearings. Torsion springs 36 are sleeved at both ends of the outer side of the rotating shaft 35. The torsion springs 36 are located inside the adjacent inner receiving grooves 33 and are fixedly connected between the inner wall of the inner receiving groove 33 and the discharge push rod 34.

[0034] Therefore, after stamping, the return spring 22 drives the bending block 21 to rotate outward around the hinge, thus avoiding jamming the stamped U-shaped sheet metal part. At this time, the discharge push rod 34, which enters the outer receiving groove 32 during the stamping process, rotates and resets around the rotation shaft 35 under the drive of the torsion spring 36. During this process, one end of the U-shaped sheet metal part is pushed upward by the discharge push rod 34, and then the U-shaped sheet metal part slides out between the two bending mechanisms 2. Compared with the prior art, the sheet metal part can be pushed out after stamping without manual removal, saving manpower and effectively improving the bending efficiency of the sheet metal part.

[0035] like Figure 3 As shown in this disclosure, the discharge mechanism 3 further includes a fixing bolt 37. The two side plates 31 are detachably connected by the fixing bolt 37. Both side plates 31 are provided with threaded holes. The fixing bolt 37 is threaded into the inside of the threaded holes. Either side plate 31 is fixedly connected to the inner wall of the base 1.

[0036] Therefore, the two separate side plates 31 can be connected using fixing bolts 37, and the two separate side plates 31 can be more convenient for installing the discharge push rod 34, the rotating shaft 35 and the torsion spring 36.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
