Description

Technical Field

[0001] This utility model belongs to the field of processing technology, and specifically relates to a bending mechanism. Background Technology

[0002] During assembly, in order to improve the connection strength between two sets of components, it is often necessary to add corner connectors at the connection corners between the two components. However, in actual assembly, due to design reasons or assembly accuracy reasons, the angle of the corner cannot match the existing corner connectors, which makes assembly impossible.

[0003] Currently, the common practice is to reprocess or remanufacture a matching corner connector on the assembly site. This necessitates the use of a bending mechanism during assembly. However, the applicant has found that while bending mechanisms are readily available on the market, inexpensive mechanisms often fail to achieve precise bending of the corner connector, resulting in significant errors and failing to meet usage requirements. Mechanisms that offer stable performance and comfortable use are generally more complex, leading to higher costs. Therefore, finding a streamlined mechanism that meets usage requirements is of high practical value. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0029] Example 1

[0030] See Figure 1-5As shown, a bending mechanism includes a base 1, on which a lead screw 2 is rotatable. A limiting plate 3 is provided on the threaded portion of the lead screw 2. The limiting plate 3 can slide on the base 1 by being driven by the lead screw 2, thereby realizing the adjustment and control of the dimensions on both sides of the corner connector through the limiting plate 3. A pressing device 4 is provided above the base 1, which presses and fixes the corner connector to be bent on the base 1. A bending device 5 is hinged to the front of the base 1, which bends the corner connector.

[0031] For further details, please refer to [link / reference]. Figure 1 As shown, in this embodiment, a receiving groove 11 is provided on the upper surface of the base 1, and the limiting plate 3 sinks into the receiving groove 11 and can slide in the receiving groove 11; in this embodiment, the front side walls of the receiving groove 11 are beveled.

[0032] For further details, please refer to [link / reference]. Figure 3 As shown, in this embodiment, the pressing device 4 includes a pair of support guide shafts 41 disposed on the base 1. A pressing plate 42 that can slide up and down is disposed on the pair of support guide shafts 41. A spring 43 is respectively sleeved on the support guide shafts 41 located between the pressing plate 42 and the base 1. A crossbeam 44 is disposed at the upper end of the pair of support guide shafts 41. A pressing module 45 that can drive the pressing plate 42 to press down is disposed on the crossbeam 44. During bending, the pressing module 45 drives the pressing plate 42 to move downward along the pair of support guide shafts 41, thereby pressing and fixing the corner connector to be bent on the base 1 by the pressing plate 42. At this time, the spring 43 is in a compressed state. After the corner connector is bent, the pressing module 45 releases the pressing on the pressing plate 42. Under the rebound force of the spring 43, the pressing plate 42 moves upward, releasing the pressing on the bent corner connector.

[0033] In this embodiment, the lower pressure plate 42 is inverted "convex" shape; the small diameter portion of the lower pressure plate 42 is adapted to the areas with beveled angles on both sides of the front end of the receiving groove 11; it should be noted that the lower pressure plate 42 is preferably flush with the front end surface of the base 1 when it does not protrude.

[0034] Furthermore, in this embodiment, see also... Figure 3As shown, the pressing module 45 includes a screw 451 and a first pad 452. The screw 451 passes vertically downward through the crossbeam 44 and is threadedly connected to the crossbeam 44. The first pad 452 is disposed at the lower end of the screw 451. During operation, by rotating the screw 451, the screw 451 is moved up and down in the crossbeam 44, thereby pressing down or releasing the pressing plate 42 through the first pad 452. In this embodiment, rotating the screw 451 clockwise moves it downward, and rotating it counterclockwise moves it upward.

[0035] Further details can be found by referring to [link / reference]. Figure 3 As shown, in this embodiment, the bending device 5 includes a hinge seat 51 connected to the base 1. A hinge plate 52 is disposed on the hinge seat 51, and a drive module 53 is disposed on the hinge plate 52 to drive its rotation. The drive module 53 drives the hinge plate 52 to rotate towards the base 1, thereby performing a bending action on the corner connector to be bent. In this embodiment, to achieve more precise control of the bending angle, see [reference needed]. Figure 2 As shown, the hinge base 51 is provided with an angle scale 511, and an arrow 521 is provided on the hinge axis to which the hinge plate 52 belongs on the same side as the angle scale 511; it should be noted that, in this embodiment, the bending angle can be between 0 and 90°, that is, as shown Figure 4 Angle at point a shown.

[0036] In this embodiment, the drive module 53 is a drive rod, which is fixed to the hinge plate 52 by welding; or, the drive rod is detachably connected to the hinge plate 52 by threaded connection; during operation, the drive rod is driven manually, thereby causing the hinge plate 52 to perform a bending action.

[0037] Example 2

[0038] Unlike Example 1, see details below. Figure 5 As shown, the pressing module 45 includes a pressing cylinder 453 fixed vertically downward on the crossbeam 44. The piston rod of the pressing cylinder 453 passes through the crossbeam 44 and is connected to a second pad 454. A guide rod 455 is provided at both ends of the second pad 454. The guide rod 455 can slide through the crossbeam 44. The driving module 53 is a driving cylinder. The rear end of the driving cylinder is hinged to the base 1, and the front end of the piston rod of the driving cylinder is hinged to the hinge plate 52.

[0039] When the corner connector to be bent is pressed down and fixed, the second pad 454 is driven to move up and down along the guide rod 455 by the pressing cylinder 453, thereby pressing down or releasing the pressing plate 42; and when the corner connector to be bent is bent, the hinge plate 52 is driven to rotate towards the base 1 by the driving cylinder, thereby realizing the bending action.

[0040] The working principle of this utility model is as follows:

[0041] During operation, first rotate the lead screw 2 to adjust the limiting plate 3 to the appropriate position, then place the corner connector to be bent into the receiving groove 11 and hold the limiting plate 3 in place; then drive the pressing plate 42 downward through the pressing module 45 to press and fix the corner connector to be bent onto the base 1; then drive the hinge plate 52 through the driving module 53 to bend it.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
