Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a bending test device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal industry are called sheet metal parts. When using sheet metal parts to manufacture some curved products, the sheet metal parts need to be bent. The width of the bending body on the hydraulic cylinder of the traditional bending device is fixed. When bending a sheet metal part with a larger width, uneven extrusion pressure will occur, and indentations of the bending body will appear on the surface of the sheet metal. When indentations appear on the sheet metal part, it will affect the normal function and aesthetics of the sheet metal part.

[0003] In response to the above problems, the prior art patent publication number CN218775417U discloses a bending test device for sheet metal processing. The first motor can drive the entire bending column to bend the sheet metal plate. The bending can be performed as a whole, which can avoid extrusion and indentation on the sheet metal. The driving motor can drive the bending column to adjust up and down to facilitate the bending of sheet metal plates of different thicknesses. This solves the problem that the existing bending device will have uneven extrusion force when bending sheet metal parts with a larger width, and the indentation of the bending body will appear on the sheet metal surface.

[0004] However, in the above method, it is impossible to ensure that the sheet metal parts are perpendicular to the bending columns when they are placed, resulting in poor bending quality. Utility Model Content

[0005] The purpose of the utility model is to provide a bending test device, which aims to solve the technical problem in the prior art that when placing sheet metal parts, it is impossible to ensure that the sheet metal parts are perpendicular to the bending column, resulting in poor bending quality.

[0006] To achieve the above-mentioned purpose, the present invention adopts a bending test device, which includes a working frame, a placement frame, a bending assembly, an alignment mechanism and a pressing assembly, wherein the placement frame and the bending assembly are arranged on the working frame, and the pressing assembly is arranged on the working frame;

[0007] The alignment mechanism includes two sliders, two L-rods, two connecting rods, two groups of alignment components, two slide rods, two springs, a block, a motor and an elliptical plate. The placement frame has two slide slots, and the two sliders are slidably connected to the corresponding slide slots respectively. The two L-rods are fixedly connected to the corresponding sliders respectively. The two ends of the connecting rod are fixedly connected to the corresponding L-rods and the corresponding alignment components respectively. One end of the slide rod passes through one of the sliders and is fixedly connected to the other slider. The block is fixedly connected to one end of the slide rod away from the slider. The two ends of the spring are fixedly connected to the corresponding sliders respectively. The motor is installed on the working frame. The output end of the motor is fixedly connected to the elliptical plate. The elliptical plates are in contact with the block and the corresponding sliders.

[0008] Wherein, the alignment assembly includes a support plate, two brackets and two alignment rollers, the support plate is fixedly connected to the corresponding connecting rod, the two brackets are fixedly connected to the support plate, and the alignment rollers are arranged on the corresponding brackets.

[0009] The clamping assembly includes a clamping cylinder, a connecting plate and a clamping piece. The clamping cylinder is installed on the work frame. The output end of the clamping cylinder is fixedly connected to the connecting plate. The clamping piece is fixedly connected to the connecting plate.

[0010] Wherein, the bending test device further includes a pushing assembly, and the pushing assembly is arranged on the working frame.

[0011] Among them, the pushing assembly includes two electric slide rails, two sliding sleeves, a cross bar, a U-shaped rod and a push plate. The two electric slide rails and the two sliding sleeves are respectively adapted to the corresponding electric slide rails, the two ends of the cross bar are respectively fixedly connected to the corresponding sliding sleeves, the U-shaped rod is fixedly connected to the cross bar, and the push plate is fixedly connected to the U-shaped rod.

[0012] Wherein, the pusher assembly further includes a protective plate, which is arranged on the pusher plate.

[0013] The cam is driven by the motor to rotate the elliptical plate, and the cam is driven by the motor to move the elliptical plate so as to abut against the movement of the block and the slider close to the elliptical plate to slide in the corresponding slide groove, thereby making the two sliders move toward each other, and the two sliders drive the two L rods to move, and the two L rods drive the two sets of alignment assemblies to align the sheet metal to be tested on the placing frame through the two connecting rods. After that, the motor drives the elliptical plate to reverse so that each component is reset, and then the pressing assembly is used to press and bend it. In this way, the technical problem that the sheet metal cannot be ensured to be perpendicular to the bending column when placing the sheet metal in the prior art, resulting in poor bending quality, can be solved.
