Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of hardware processing, and in particular, to a bending device for processing of hardware. BACKGROUND

[0002] In power engineering, hardware is used to connect and fasten various types of wires and cables, ensuring the stability and reliability of power transmission. The processing of hardware involves a variety of complex processes, among which the bending process is a key link that determines the quality and applicability of the hardware.

[0003] Traditional hardware bending devices have many limitations. On the one hand, the clamping assemblies of most existing devices have poor flexibility. When facing hardware of different shapes and sizes, it is difficult to quickly and accurately adjust the clamping. Manual operation is often required multiple times, which not only consumes a lot of time and labor, but also easily causes displacement of the hardware during the bending process due to unstable clamping, seriously affecting the processing precision and quality of the product. For example, when processing hardware with special curvature or irregular shape, the clamping assembly of the traditional fixed structure cannot closely fit the hardware profile, resulting in bending angle deviation and increasing the scrap rate.

[0004] On the other hand, the driving bending assembly of existing bending devices has a single function. The common bending mechanism can only achieve simple single-angle bending. For some hardware that needs complex multi-angle bending, it cannot meet the processing needs. Moreover, the driving power is insufficient, and when bending hardware made of high-strength metal material, problems such as incomplete bending and surface scratching of the hardware are easily caused, greatly limiting the application range and product performance improvement of the hardware.

[0005] In addition, the traditional device also has obvious defects in overall coordination and automation. There is a lack of effective linkage mechanism between the components, and the operator needs to control multiple links such as clamping, turning, and bending independently. The operation process is complicated, the work efficiency is low, and it is difficult to adapt to large-scale and high-efficiency modern production needs. CONTENT OF THE INVENTION

[0035] As shown in Figures 1-4 , which shows a bending device for processing connecting fittings in an embodiment of the present disclosure, comprising:

[0036] A processing plate 1, the bottom of the processing plate 1 is provided with a supporting leg 2;

[0037] An adjusting and clamping assembly 3 is arranged on the processing plate 1;

[0038] A driving and bending assembly 4 is arranged at the bottom of the processing plate 1;

[0039] The adjusting and clamping assembly 3 includes a driving shaft 3-1 inserted into the processing plate 1, a self-rotating sleeve 3-2 is sleeved on the driving shaft 3-1, a turnover arm 3-3 is arranged on the side wall of the self-rotating sleeve 3-2, a fixed clamp 3-4 is arranged at the end of the turnover arm 3-3, a sliding cavity 3-5 is arranged in the fixed clamp 3-4, a driving gear 3-6 is arranged in the sliding cavity 3-5, an engaging rack 3-7 is arranged on the side wall of the driving gear 3-6, an insertion strip 3-8 is connected at the end of the engaging rack 3-7, and an extension arm 3-9 is arranged at the end of the insertion strip 3-8. The extension arm 3-9 is fixedly connected with the self-rotating sleeve 3-2.

[0040] The driving and bending assembly 4 includes a bending slot 4-1, a bending arm 4-2 is arranged in the bending slot 4-1, a supporting disc 4-3 is arranged at the bottom of the processing plate 1, a large-torque motor 4-4 is arranged on the side wall of the supporting disc 4-3, a driving sleeve 4-5 is arranged at the output end of the large-torque motor 4-4, the driving sleeve 4-5 is fixedly connected with the bending arm 4-2, and the upper end of the bending arm 4-2 extends out of the bending slot 4-1.

[0041] In some examples, after the self-rotating sleeve 3-2 rotates, the self-rotating sleeve 3-2 on the processing plate 1 drives the turnover arm 3-3 to rotate, the two turnover arms 3-3 rotate at the same time, and the fittings are clamped by the two corresponding fixed clamps 3-4. At this time, the driving gear 3-6 can be driven to rotate by the motor, the turnover arm 3-3 can be driven to extend and retract by the engaging rack 3-7, the extension arm 3-9 is extended, and the fixed clamp 3-4 is extended to clamp the fittings.

[0042] After the large torque motor 4-4 drives the driving sleeve 4-5 to rotate, the bending arm 4-2 extends out of the bending groove 4-1, and a huge force is applied to the fitting through the bending arm 4-2, so that the fitting is bent and formed.

[0043] As shown in Figures 1-4 The embodiment provides a vertical frame 3-10 on the bottom surface of the processing plate 1, a strip-shaped groove 3-11 is opened on the vertical frame 3-10, a driving motor 3-12 is arranged on the vertical frame 3-10, the driving motor 3-12 is fixedly connected between the output end and the driving shaft 3-1, and the driving motor 3-12 is fixedly connected with the strip-shaped groove 3-11 through screwing.

[0044] In some examples, the driving motor 3-12 on the vertical frame 3-10 drives the rotating sleeve 3-2 to rotate, thereby providing the rotating power of the rotating sleeve 3-2.

[0045] For example, as shown in Figure 2 The large torque motor 4-4 is fixedly screwed between the support disc 4-3 through a bolt.

[0046] In some examples, the large torque motor 4-4 is fixedly screwed on the support disc 4-3, so that the large torque motor 4-4 is fixed.

[0047] For example, as shown in Figure 4 The inner side wall of the sliding cavity 3-5 is provided with an extension groove 5, and one end of the meshing rack 3-7 is inserted into the inside of the extension groove 5.

[0048] In some examples, the extension groove 5 can increase the movement of the meshing rack 3-7, and the extension distance of the extension arm 3-9 is increased.

[0049] For example, as shown in Figure 1 The number of the turnover arms 3-3 is three, the three turnover arms 3-3 are equidistantly arranged on the side wall of the rotating sleeve 3-2, and the structures of the fixed clamps 3-4 at the ends of each turnover arm 3-3 are different.

[0050] In some examples, different fixed clamps 3-4 are selected by switching through the plurality of turnover arms 3-3.

[0051] For example, as shown in Figure 1 The plurality of fixed clamps 3-4 are respectively in arc-shaped structures, straight plate structures and semicircular structures.

[0052] In some examples, the fixed clamps 3-4 of different specifications are used in cooperation for fittings of different shapes.

[0053] For example, as shown in Figure 1As shown, the support leg 2 is a triangular steel structure, which is located at the bottom of the four corners of the processing plate 1, and the output end of the driving motor 3-12 is movably connected to the processing plate 1 through a bearing.

[0054] In some examples, the support leg 2 of the triangular steel structure is more stable.

[0055] According to the shape and size of the connecting fitting, a fixed clamp 3-4 with a suitable structure is selected, for example, if the fitting is circular, a fixed clamp 3-4 with a circular arc structure can be selected. Rotate the driving gear 3-6, drive the insertion strip 3-8 and the extension arm 3-9 to move through the meshing rack 3-7, thereby adjusting the opening size of the fixed clamp 3-4, placing the fitting in the fixed clamp 3-4, and then rotating the driving gear 3-6 in the opposite direction to make the fixed clamp 3-4 clamp the fitting. Start the driving motor 3-12, which drives the driving shaft 3-1 to rotate, which drives the rotation sleeve 3-2 to rotate, and the turnover arm 3-3 on the rotation sleeve 3-2 and the fixed clamp 3-4 rotate accordingly, realizing the switching between different fixed clamps 3-4. Start the large-torque motor 4-4, which drives the bending arm 4-2 to rotate through the driving sleeve 4-5, and the bending arm 4-2 exerts a bending force on the fitting in the fixed clamp 3-4, so that the fitting is bent in the bending groove 4-1 for bending processing. After the processing of one fitting is completed, the fixed clamp 3-4 is loosened, the processed fitting is taken out, and a new fitting to be processed is placed in the fixed clamp 3-4. Repeat the above operations to process the next fitting.
