[0002] Crimping machines are essential tools in the power industry for splicing conductors during basic line construction and maintenance. Crimping machines are categorized into hydraulic crimping machines, large-tonnage crimping machines (punch presses), insulating terminal crimping machines, and split-type crimping pliers. Hand-cranked hydraulic crimping machines work by placing the workpiece to be crimped into the die inside the crimping pliers. A moving mechanism moves the pliers to the appropriate crimping position, and a hydraulic pump station provides high-pressure hydraulic oil to drive the hydraulic pliers to perform the crimping.

[0034] The technical solution in this application embodiment effectively solves the technical problems of existing pneumatic crimping machines requiring workers to hold the wires by hand, which poses a safety hazard of worker hand injury, and the wires being prone to shaking when held, affecting the aesthetics and quality of the crimped wires. The overall idea is as follows:

[0035] In view of the problems existing in the prior art, the present invention provides a pneumatic crimping machine for power engineering with safety protection function, including a workbench 1, a support leg 101 fixedly connected to the bottom of the workbench 1, a controller 102 provided on the side of the workbench 1, a support plate 103 fixedly connected to the top center of the workbench 1, a crimping mechanism 4 provided below the support plate 103, and a fixing component 2 provided on one side of the surface of the workbench 1.

[0036] In some embodiments, the fixing component 2 includes a mounting plate 21, which is fixedly mounted on the top side of the workbench 1. A lower clamping groove 22 is fixedly connected above the mounting plate 21, and an upper clamping groove 23 is provided above the lower clamping groove 22. Restoring springs 24 are fixedly connected between the top two sides of the mounting plate 21 and the upper clamping groove 23. A guide rod 25 is provided in the middle of the restoring spring 24. A pull rod 26 is fixedly connected to the top middle of the upper clamping groove 23. The guide rod 25 is slidably engaged with the upper clamping groove 23. Figures 1 to 4 As shown, pull the lever 26 upward to pass the wire through the slot between the lower clamping groove 22 and the upper clamping groove 23, and place the end to be crimped above the lower crimping block 44. Release the lever 26, and the upper clamping groove 23 moves downward along the direction of the guide rod 25 under the force of the restoring spring 24 to fix the wire.

[0037] Example 2

[0038] Based on Example 1, this application presents a feasible technical solution for a pneumatic crimping machine for power engineering with safety protection functions. The overall concept is as follows:

[0039] In some embodiments, the crimping mechanism 4 includes a cylinder 41, which is fixedly mounted on the top center of the support plate 103. A rectangular frame 42 is fixedly connected to the movable end of the cylinder 41. A crimping block 43 is fixedly connected to the bottom of the rectangular frame 42. A lower crimping block 44 corresponding to the crimping block 43 is fixedly connected to the surface of the worktable 1. An ejection assembly 45 is provided in the middle of the rectangular frame 42. Figures 1 to 4 As shown, the cylinder 41 is activated, which drives the rectangular frame 42 and the upper pressing block 43 to move downward to press the wire.

[0040] In some embodiments, the ejector assembly 45 includes a connecting spring 451, which is fixedly connected to the upper part of the inner wall of the rectangular frame 42. A connecting plate 452 is fixedly connected to the bottom of the connecting spring 451, and an ejector rod 453 is fixedly connected to the bottom of the connecting plate 452. The ejector rod 453 and the connecting plate 452 are integrally welded together. The ejector rod 453 is slidably engaged with the pressing block 43. Figures 1 to 4 As shown, during the crimping process, the ejector rod 453 compresses the connecting spring 451, causing the connecting spring 451 to contract. After the crimping is completed, the cylinder 41 retracts while the connecting spring 451 returns to its original position. Its restoring force causes the ejector rod 453 to move downward relative to the crimping block 43, which can prevent the wire from sticking to the surface of the crimping block 43 after crimping.

[0041] In some embodiments, a telescopic rod 46 is fixedly welded between the rectangular frame 42 and the support plate 103, such as... Figures 1 to 4 As shown, the telescopic rod 46 makes the rectangular frame 42 more stable when it moves.

[0042] In this embodiment, when the cylinder 41 is activated, it drives the rectangular frame 42 and the upper pressing block 43 to move downward to press the wire. At the same time as pressing, the ejector rod 453 compresses the connecting spring 451, causing the connecting spring 451 to contract. After the pressing is completed, the cylinder 41 retracts and the connecting spring 451 returns to its original position. Its restoring force causes the ejector rod 453 to move downward relative to the pressing block 43, which can prevent the wire from sticking to the surface of the pressing block 43 after pressing. The telescopic rod 46 can make the rectangular frame 42 more stable when moving.

[0043] Working principle: In use, first pull the lever 26 upwards to pass the wire through the slot between the lower clamping groove 22 and the upper clamping groove 23, and place the end to be crimped above the lower crimping block 44. Release the lever 26, and the upper clamping groove 23 moves downwards along the guide rod 25 under the force of the restoring spring 24 to fix the wire. Activate the cylinder 41 to drive the rectangular frame 42 and the upper crimping block 43 downwards to crimp the wire. At the same time as crimping, the ejector rod 453 compresses the connecting spring 451, causing the connecting spring 451 to contract. After crimping is completed, the cylinder 41 retracts while the connecting spring 451 returns to its original position. Its restoring force causes the ejector rod 453 to move downwards relative to the crimping block 43, which can prevent the wire from sticking to the surface of the crimping block 43 after crimping. The telescopic rod 46 can make the rectangular frame 42 more stable when moving.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
