Description

Technical Field

[0001] This utility model relates to the field of mechanical bending, and in particular to a bending device for supporting connecting parts. Background Technology

[0002] Currently, the support connectors are bent manually. During the bending process, it has been found that manual bending is very time-consuming and cannot meet the needs of mass production, resulting in low efficiency. At the same time, the bending operation is unstable and prone to various defects, such as surface cracks or whitening, unstable dimensions, uneven creases, and bending line deviation, resulting in unstable quality of the bent support connectors.

[0003] Chinese patent CN221775243U discloses an automatic bending device for plastic parts, comprising: a worktable (1); a positioning assembly disposed on the worktable (1), including positioning fixtures (5) arranged opposite each other, and rotary clamping cylinders (3) disposed at both ends of the positioning fixtures (5), wherein the positioning fixtures (5) are used to place the two ends of the plastic parts, and the rotary clamping cylinders (3) are used to clamp the ends of the plastic parts; and a bending assembly disposed on the worktable (1), which is located between the rotary clamping cylinders (3) arranged opposite each other, for bending the weak points of the plastic parts. This patent relies solely on lever cylinders to apply vertical pressure, and there is no pressing mechanism in the middle of the workpiece, which leads to stress concentration and warping when bending thin-walled parts. Utility Model Content

[0004] The purpose of this invention is to provide a bending device for supporting connectors. Through targeted optimization, the bending device provided by this invention can significantly reduce the defect rate of manual bending. For high-precision parts, mechanical bending is used to meet quality requirements.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A bending device for supporting a connector, comprising:

[0007] Fixing plate;

[0008] Fixed fixture: It is fixed above the fixed plate;

[0009] Movable fixture: It is slidably disposed above the fixed plate. The two movable fixtures are respectively located on the front and rear sides of the fixed fixture. The movable fixtures are used to place the two ends of the support connector.

[0010] First cylinder: It is located above the fixed plate. The two first cylinders are respectively connected to a movable tool. The first cylinder is used to push the two movable tools to move towards each other, thereby driving the support connector to bend inward.

[0011] The second cylinder: one end of the second cylinder is fixed above the fixed plate, and the other end of the second cylinder is located above the fixed fixture. The second cylinder is used to press the support connector.

[0012] In one embodiment of this utility model, the bending device further includes a frame, and the fixing plate is disposed above the frame.

[0013] In one embodiment of this utility model, the bending device further includes a sliding component, and the movable fixture is slidably connected to the fixed plate through the sliding component.

[0014] In one embodiment of this utility model, the sliding assembly includes a guide rail and a slider. The guide rail is fixed to a fixed plate, and the slider is fixed below the movable fixture. The slider and the guide rail are slidably connected.

[0015] As a preferred technical solution, the guide rail is equipped with a position sensor, which is used to accurately detect the travel position of the moving tooling.

[0016] In one embodiment of this utility model, the second cylinder is provided with a pressure head at one end above the fixed fixture. The pressure head is positioned directly above the fixed fixture and can be moved up and down reciprocally by the second cylinder. The pressure head is used to press the support connector.

[0017] As a preferred technical solution, a pressure sensor is provided below the pressure head. The pressure sensor is used to monitor the bending force and pressing force in real time to ensure that the applied force is within a preset safe and effective range, and to avoid overload damage to the workpiece or underpressure leading to poor forming.

[0018] In one embodiment of this utility model, the bending device further includes an electrical control box, which is connected to the first cylinder and the second cylinder.

[0019] In one embodiment of this utility model, the electrical control box is equipped with a power switch, an emergency stop button, and a working indicator light.

[0020] In one embodiment of this utility model, the length of the bending device is 700-800mm, preferably 775mm.

[0021] In one embodiment of this utility model, the width of the bending device is 350-450mm, preferably 400mm.

[0022] In one embodiment of this utility model, the height of the bending device is 1100-1200mm, preferably 1135mm.

[0023] As a preferred technical solution, the maximum external dimensions of the support connector are: length 111.65mm, width 19.89mm, and height 6.8mm.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This utility model is a process for precisely bending support connectors using specialized equipment through mechanical bending. Compared with manual bending, automatic mechanical bending is a process that achieves high precision and high efficiency bending of plastic parts through the coordinated work of CNC equipment tooling and automated systems. Its structural design has significant features. Through structural optimization, this bending device achieves high precision and high efficiency batch processing.

[0026] 2. This invention achieves symmetrical bending force control by driving two moving fixtures on both sides to move towards each other along the guide rail and the slider using a first cylinder. Combined with the vertical pressing action of the pressure head driven by the second cylinder directly above the fixed fixture, a stable downward pressure is applied to the middle fixed part of the support connector during the bending process. This three-point coordinated force application mechanism (the two moving fixtures pull inward, and the middle pressure head presses downward) effectively overcomes the warping deformation problem caused by stress concentration when bending thin-walled parts. At the same time, the continuous pressing force of the pressure head helps to completely eliminate the springback deformation of the material, ensuring accurate and stable bending angles and a uniform bending state. This significantly improves the bending consistency, production efficiency, and product yield of the support connector, meeting high-standard quality requirements.

[0027] 3. The bending device provided by this utility model adopts mechanical bending, which has high production efficiency, is suitable for batch processing, has high processing accuracy, stable quality, reduces reliance on manual labor, reduces human defects, lowers costs, reduces defect rate, and saves time.
