Description

Technical Field

[0001] The utility model relates to the technical field of corner bending devices, in particular to an automatic foot bending device for connection terminals. Background Art

[0002] Terminal blocks are products specially used to connect accessories, which can make good and stable connections between wires. When in use, insert the wires into the holes at both ends, and then use screws to squeeze and fix the wires, which can quickly complete the connection and fixation of the wires, and also facilitate disconnecting the lines at any time.

[0003] When processing and producing the terminal block, a bending device is needed to bend it to give it a special structure and make it easier to use. The bending device is to fold the component at a certain angle to give it a certain curvature.

[0004] According to the search, the Chinese patent document, announcement number: CN212257973U, discloses an automatic bending device for terminal blocks, which includes a frame and a hydraulic press, wherein the hydraulic press is fixedly connected to the top of the frame, a through slot is opened on one side of the inner bottom of the frame, a pad is fixedly connected to the inner bottom of the frame, and the upper part of the outer wall of the pad is kept in the same horizontal line with the lower part of the inner wall of the through slot, a telescopic rod is inserted into the upper part of the inner part of the frame, and the upper part of the telescopic rod passes through the frame and is fixedly connected to the hydraulic press. The device can pre-tighten the legs before bending through the cooperation of the telescopic rod and the pressure plate, avoiding deformation or even damage of the middle part of the workpiece during bending, avoiding unnecessary losses, and can facilitate the staff to process workpieces of various shapes and curvatures according to needs through the mold that can be disassembled and replaced by bolts, which is convenient for the staff to use. However, the device has its shortcomings. For processing components of different lengths, the bending mechanism in the device cannot adjust the distance between each other. Therefore, it can only process components with a length within a certain range, and its applicability is low. Secondly, the device lacks a structure for pre-centering the components. This can easily lead to the processing components being transferred to the frame. Due to the lack of center alignment, after the pressure plate fixes the components, the lengths of the components extending at both ends of the pad are inconsistent, affecting the asymmetric effect of the bending angles on both sides.
