Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically a bending device for thin sheet metal parts. Background Technology

[0002] Sheet metal parts are products manufactured from thin metal sheets through processes such as shearing, punching, cutting, compounding, bending, welding, riveting, splicing, and forming. These processes endow sheet metal parts with diverse structures and functions, and they are widely used in various fields such as automobile manufacturing, machining, electronic equipment, and architectural decoration. Sheet metal parts not only possess good strength and stability but also enable lightweight design, meeting the stringent requirements of different industries for product appearance and performance. During bending processes, they are generally completed using the cooperation of upper and lower dies.

[0003] In existing technologies, the lower die is usually not adjustable and can only bend sheet metal parts to a fixed angle, which makes the bending device less versatile and flexible, and difficult to meet the processing requirements of sheet metal parts with different specifications and bending angles.

[0004] Therefore, this utility model provides a bending device for thin sheet metal parts. Utility Model Content

[0005] To overcome the shortcomings of existing technology and solve the problem that the lower mold cannot be adjusted and can only bend sheet metal parts to a fixed angle, resulting in poor versatility and flexibility of bending devices, making it difficult to meet the processing requirements of sheet metal parts with different specifications and bending angles.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a thin sheet metal bending device of this utility model, including a base plate, wherein a bending mechanism is provided on the base plate, and the bending mechanism includes:

[0007] The lower mold assembly includes a pair of fixed blocks fixed to the top of the base plate. A pair of lower templates are rotatably connected between the opposite side walls of the pair of fixed blocks via a pair of first rotating shafts. A pair of arc-shaped rods are fixed to the side walls of the lower templates. A set of sliding holes is fixed to the top of the base plate. The arc-shaped rods are slidably connected in the sliding holes. An adjustment assembly for adjusting the pair of lower templates is provided on the base plate.

[0008] The upper mold assembly is set on the base plate and is used to extrude sheet metal parts.

[0009] Preferably, the adjustment assembly includes a pair of first concave blocks fixed to the top of the base plate, and a first electric actuator is rotatably connected between the opposite sidewalls of the first concave blocks via a second rotating shaft.

[0010] Preferably, a second concave block is fixedly connected to the side of the lower template near the first concave block, and the telescopic end of the first electric actuator is rotatably connected between the opposite sidewalls of the second concave block via a third rotating shaft.

[0011] Preferably, the upper mold assembly includes a pair of upright plates fixed to the top of the base plate, each upright plate having a sliding groove, a sliding block being slidably connected within the sliding groove, a fixing plate being fixed to the side wall of the sliding block, and a pair of upper modules being rotatably connected between the opposite side walls of the pair of fixing plates via a pair of fourth rotating shafts.

[0012] Preferably, a pair of arc-shaped grooves are provided on the fixed plate, and sliding rods are fixedly connected to both sides of the upper module. The sliding rods are slidably connected in the arc-shaped grooves. A first support plate is fixedly connected to the top of the pair of upright plates, and a pair of second electric push rods are fixedly connected to the bottom of the first support plate. The telescopic ends of the second electric push rods are fixedly connected to the top of the sliding block.

[0013] Preferably, the upper module has an extrusion groove on its side wall, a second support plate is fixedly connected to the top of the pair of fixed plates by a set of fixed rods, a pair of third electric push rods are fixedly connected to the bottom of the second support plate, and an extrusion roller is fixedly connected to the telescopic end of the pair of third electric push rods, and the extrusion roller is located between the pair of extrusion grooves.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The sheet metal bending device of this utility model can solve the problem in the prior art that the lower mold is usually not adjustable and can only bend the sheet metal parts to a fixed angle, which makes the bending device less versatile and flexible and difficult to meet the processing requirements of sheet metal parts with different specifications and bending angles by adjusting the angle of a pair of lower molds through the setting adjustment components.

[0016] 2. The sheet metal bending device of this utility model allows the extrusion roller to be raised and lowered via a third electric push rod. This, in turn, causes a pair of sliding blocks to descend via a second electric push rod. When a pair of upper modules are positioned between a pair of lower templates, the descending extrusion rollers extrude pressure onto the walls of the extrusion grooves on the upper modules. This allows the upper modules to rotate around a fourth rotating axis, ensuring that the sidewalls of the upper modules remain parallel to the lower templates. This improves bending accuracy and ensures that the sheet metal parts do not skew or deform during the bending process. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a sheet metal bending device according to an embodiment of the present invention includes a base plate 1, on which a bending mechanism is provided. The bending mechanism includes: a lower die assembly, including a pair of fixing blocks 2 fixed to the top of the base plate 1, a pair of lower templates 3 rotatably connected between the opposite side walls of the pair of fixing blocks 2 via a pair of first rotating shafts, a pair of arc rods 4 fixed to the side walls of the lower templates 3, a set of sliding holes 5 fixed to the top of the base plate 1, the arc rods 4 slidably connected in the sliding holes 5, and an adjustment assembly for adjusting the pair of lower templates 3 provided on the base plate 1; and an upper die assembly, provided on the base plate 1 for extruding the sheet metal part.

[0025] During operation, the angle of a pair of lower templates 3 can be adjusted by the set adjustment components, which solves the problem in the existing technology that the lower mold is usually not adjustable and can only bend sheet metal parts to a fixed angle, resulting in poor versatility and flexibility of the bending device, making it difficult to meet the processing requirements of sheet metal parts with different specifications and bending angles.

[0026] The adjustment assembly includes a pair of first concave blocks 6 fixed to the top of the base plate 1, and a first electric push rod 7 is rotatably connected between the opposite side walls of the first concave blocks 6 via a second rotating shaft.

[0027] The lower template 3 is fixed to the side of the first concave block 6 with the second concave block 8. The telescopic end of the first electric push rod 7 is rotatably connected between the opposite side walls of the second concave block 8 through the third rotating shaft.

[0028] During operation, by setting the extension and retraction of the first electric push rod 7, the lower template 3 can be pulled by the second concave block 8 to rotate around the first rotating axis, thereby adjusting the angle of the lower template 3 so that it can cooperate with the lower template 3 on the other side to complete the adjustment of the bending angle, thus adapting to different bending angles.

[0029] The upper mold assembly includes a pair of upright plates 9 fixed to the top of the base plate 1. A sliding groove 10 is provided on the upright plate 9. A sliding block 11 is slidably connected in the sliding groove 10. A fixing plate 12 is fixed to the side wall of the sliding block 11. A pair of upper modules 13 are rotatably connected between the opposite side walls of the pair of fixing plates 12 through a pair of fourth rotating shafts.

[0030] A pair of arc-shaped grooves 14 are provided on the fixed plate 12. Sliding rods 15 are fixed to both sides of the upper module 13. The sliding rods 15 are slidably connected in the arc-shaped grooves 14. A first support plate 16 is fixed to the top of a pair of upright plates 9. A pair of second electric push rods 17 are fixed to the bottom of the first support plate 16. The telescopic end of the second electric push rod 17 is fixed to the top of the sliding block 11.

[0031] The upper module 13 has an extrusion groove 18 on its side wall. A pair of fixed plates 12 are fixed to the top of a second support plate 19 by a set of fixed rods. A pair of third electric push rods 20 are fixed to the bottom of the second support plate 19. An extrusion roller 21 is fixed to the telescopic end of the pair of third electric push rods 20, and the extrusion roller 21 is located between the pair of extrusion grooves 18.

[0032] During operation, the third electric push rod 20 can raise and lower the extrusion roller 21, which in turn drives the second electric push rod 17 to lower a pair of sliding blocks 11. When the pair of upper modules 13 are located between the pair of lower templates 3, the extrusion roller 21 lowers and extrudes the walls of the extrusion grooves 18 opened on the pair of upper modules 13. This allows the upper modules 13 to rotate around the fourth rotating axis, so that the side wall of the upper module 13 can remain parallel to the lower template 3, improving the accuracy of bending and ensuring that the sheet metal parts will not be skewed or deformed during the bending process.

[0033] Working principle: By adjusting the angle of a pair of lower templates 3 using the set adjustment components, the problem of the lower mold being unable to be adjusted in the existing technology, which can only bend sheet metal parts to a fixed angle, is solved. This results in poor versatility and flexibility of the bending device, making it difficult to meet the processing requirements of sheet metal parts with different specifications and bending angles.

[0034] By setting the extension and retraction of the first electric push rod 7, the lower template 3 can be pulled by the second concave block 8 to rotate around the first rotating axis, thereby adjusting the angle of the lower template 3 so that it can cooperate with the lower template 3 on the other side to complete the adjustment of the bending angle, thus adapting to different bending angles.

[0035] The third electric push rod 20 allows the extrusion roller 21 to rise and fall. The second electric push rod 17 drives a pair of sliding blocks 11 to descend, so that when a pair of upper modules 13 are located between a pair of lower templates 3, the extrusion roller 21 descends and extrudes the walls of the extrusion grooves 18 opened on the pair of upper modules 13. This allows the upper modules 13 to rotate around the fourth rotating axis, so that the side walls of the upper modules 13 can remain parallel to the lower templates 3, improving the accuracy of bending and ensuring that the sheet metal parts will not be skewed or deformed during the bending process.
