Description

Technical Field

[0001] The present application relates to the field of conductive part bending devices, and in particular to a conductive part bending device. Background Art

[0002] In the field of radio frequency communications, metal sheets, as conductive components in RF components, are crucial for optimizing signal transmission performance. With the continuous advancement of communication technology, the processing quality of precision conductive components directly affects system performance and reliability.

[0003] To ensure the precision and stability of conductive parts, sheet metal bending is currently commonly performed using various automated machines or CNC machine tools. These devices significantly improve bending accuracy and production efficiency, demonstrating significant advantages in mass production. Automated machines achieve extremely high precision with each bend through precise programming and control, while CNC machine tools utilize advanced software algorithms and high-precision sensors to precisely bend sheet metal. In addition to automated machines and CNC machine tools, some manufacturers also use traditional pneumatic or hydraulic press brakes. While these machines offer slightly lower precision and efficiency, they can still meet production requirements under specific process requirements.

[0004] However, these large-scale bending machines are expensive to invest in and require significant floor space, making them impractical for small-batch production. Furthermore, if such equipment fails, repairs are costly and difficult, significantly impacting production efficiency. Consequently, existing bending equipment struggles to meet the demands of small-scale production, especially when frequent bending tool changes are required, resulting in a significant lack of flexibility. Utility Model Content

[0008] By employing this technical solution, the lower die on the fixed base is used to position the metal sheet, and the plug-in fit between the ram and the lower die ensures stable clamping of the metal sheet. The pressure rod slides vertically and is driven by the lifting assembly, allowing the ram to accurately enter the lower die during the pressing process, pressing the metal sheet tightly against the groove structure of the lower die, ultimately completing the precise bending operation. This conductive part bending device can achieve precise bending of metal sheets, is suitable for small-scale production needs, and improves the convenience of on-site maintenance.

[0011] Optionally, a threaded hole is provided on the side wall of the mounting portion and connected to the mounting groove. The fastener is a tightening bolt that is threadedly rotated through the threaded hole. The tightening bolt is rotated through the threaded hole and tightens the top of the pressure head against the side wall of the mounting groove away from the threaded hole.

[0012] By adopting the above technical solution, the tightening bolt is rotated to pass through the threaded hole, and the top of the pressure head is tightened against the side wall of the installation groove away from the threaded hole, so that the pressure head can be quickly fixed and replaced, and the flexibility and adaptability of the device are improved.

[0013] Optionally, a mounting plate is bolted to the fixed base, and multiple mounting plates can be stacked and bolted as needed.

[0014] By adopting the above technical solution, the mounting plates can be stacked according to actual needs to achieve multi-layer superposition, so that the device can flexibly adjust the height in different application scenarios, thereby adapting to the operation requirements of different heights and improving the flexibility and versatility of the device.

[0015] Optionally, a wedge-shaped groove is provided on one side of the mounting plate located on the upper layer, and a wedge-shaped block is provided at the end of the lower mold facing the wedge-shaped groove, and the wedge-shaped block is plug-fitted into the wedge-shaped groove.

[0016] By adopting the above technical solution, the wedge block and the wedge groove are plugged into each other, so that the lower mold can be quickly positioned and firmly installed on the mounting plate, which simplifies the installation process of the lower mold and improves the efficiency and convenience of replacing the lower mold.

[0017] Optionally, a rotating shaft is rotatably provided on the side wall of the top of the fixed base, and a cavity is opened on the top of the fixed base, the end of the rotating shaft extends into the cavity, the axial direction of the rotating shaft is perpendicular to the length direction of the pressure rod, and the lifting assembly includes a rack vertically arranged on the pressure rod and a gear sleeved on the rotating shaft, the gear and the rack are both located in the cavity, and the gear and the rack are meshed, and a downward handle is provided at the end of the rotating shaft extending out of the fixed base.

[0018] By employing this technical solution, the operator can rotate the gear by pressing down on the handle. The rotating gear drives the meshing rack downward, causing the pressure rod and the ram to move downward synchronously until the ram presses against the upper surface of the metal, forcing the bottom end of the ram and the upper surface of the lower die edge to press against each other, thus bending the metal sheet. This manual operation enables precise control of the pressure rod, achieving accurate bending of the metal sheet.

[0019] Optionally, a fixed block is provided on the side wall of the fixed base facing the lower mold, and the fixed block is located below the rack. The pressure rod slides vertically through the fixed block, and a supporting ring is provided on the pressure rod below the rack, and a compression spring is sleeved on the pressure rod, and the compression spring abuts against the side wall opposite to the supporting ring and the fixed block.

[0020] By adopting the above technical solution, the setting of the fixed block provides guidance and limiting functions for the lifting and lowering of the pressure rod, and the compression spring abutting between the fixed block and the support ring automatically resets by the elastic force of the compression spring, so that after the operator releases the downward handle, the pressure rod can rise autonomously, thereby improving the convenience of use and work efficiency of the device.

[0021] Optionally, the pressing handle is detachably provided on the end portion of the rotating shaft extending out of the fixed base, the end portion of the rotating shaft extending out of the fixed base is provided with a gear ring, the side wall of the pressing handle facing the end portion of the rotating shaft is provided with an assembly groove, the inner side wall of the assembly groove is provided with a gear groove which is engaged with the gear ring, and the assembly groove is plugged into and fitted with the end portion of the rotating shaft with the gear ring.

[0022] By adopting the above technical solution, the push-down handle serves as a manual operating component. The meshing arrangement between the gear ring and the tooth groove not only limits the end of the rotating shaft in the direction of rotation, thereby improving the stability of the connection between the push-down handle and the end of the rotating shaft, but also enables rapid replacement or maintenance of the manual operating component. Furthermore, the push-down handle can be removed from the device when not in use, thereby preventing the pressure head from being damaged by accidental pressing of the push-down handle while walking, thereby improving the installation efficiency of the device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The lower die on the fixed base is used to position the metal sheet. The plug-in fit between the ram and the lower die ensures stable clamping of the metal sheet. The pressure rod slides vertically and is driven by the lifting assembly, allowing the ram to accurately enter the lower die during the pressure application process, thereby pressing the metal sheet tightly and fitting it into the groove structure of the lower die, ultimately completing the precise bending operation. This conductive part bending device can achieve precise bending of metal sheets, is suitable for small-scale production needs, and improves the convenience of on-site maintenance.

[0025] 2. The top of the pressure head is inserted into the mounting groove at the bottom of the mounting part and fixed by fasteners, so that a detachable connection is formed between the pressure head and the mounting part, which facilitates the replacement of the pressure head, thereby improving the flexibility and applicability of the device;
