Description

Technical Field

[0001] The utility model relates to the technical field of cable crimping devices, in particular to a cable crimping machine used in power engineering. Background Art

[0002] Crimping machines are necessary tools for the power industry to carry out crimping of power cables during line infrastructure construction and line maintenance. Nowadays, with the continuous development of society, the power engineering industry has developed rapidly, and the importance of crimping machines has become more and more prominent. Crimping machines are usually divided into hydraulic crimping machines, large-tonnage crimping machines (punches), insulated terminal crimping machines, crimping pliers split crimping machines, hand-cranked hydraulic crimping machines, etc. When working, the crimping parts on the power cable (such as: terminal blocks on the power cable, butt copper tubes, etc.) are placed in the die in the crimping pliers, and the driving mechanism pushes the crimping pliers (such as: hydraulic pump stations provide hydraulic high-pressure oil to push hydraulic pliers) to work for crimping.

[0003] At present, the existing side pressure unit is set up so that the two pushing members of the side pressure unit are used to push the two side pressure blocks closer to each other as the crimping plate is pressed down, so that the two side pressure blocks respectively press the left and right sides of the outer circumference of the power cable; at the same time, the crimping plate and the cable placement platform respectively press the upper side and lower side of the outer circumference of the power cable; it can be achieved that the crimping part on the power cable is applied with a clamping force in four directions of up, down, left and right, so that during the clamping process, the force on the outer circumference of the crimping part on the power cable is more uniform, avoiding the generation of a gap between the crimping part and the wire core of the power cable after crimping, and making the crimping part and the wire core tightly connected. The invention can cooperate with the crimping parts on the power cable and can effectively avoid the crimping cracks caused by the uneven stress on the outer circumference of the crimping parts on the power cable during the pressing process, and solves the technical problem that the existing crimping machine can only apply the pressing force to the crimping parts on the power cable in two opposite directions when pressing the crimping parts on the power cable, so that the outer circumference of the crimping parts on the power cable will be unevenly stressed during the pressing process, which can easily cause a gap to be generated between the crimping parts and the wire core of the power cable after crimping, thereby affecting the close fit between the crimping parts and the wire core, and may cause the crimping cracks caused by the uneven stress on the outer circumference of the crimping parts on the power cable during the pressing process.

[0004] For example, a power cable crimping machine disclosed in the authorization number CN116937273A includes a cable placement table, a frame fixedly connected to the cable placement table, a driving unit fixedly installed on the frame, a crimping plate installed on the output end of the driving unit, and a side pressing unit arranged between the crimping plate and the cable placement table; the side pressing unit includes two symmetrically arranged side pressing mechanisms, the side pressing mechanism includes a side pressing block arranged on the cable placement table, and a pushing member installed between the crimping plate and the side pressing block; the cable placement table is used to support the lower side of the outer peripheral surface of the power cable, the crimping plate is correspondingly arranged above the cable placement table, and the driving unit is used to drive the crimping plate to press down so that the crimping plate presses the upper side of the outer peripheral surface of the power cable; the two pushing members of the side pressing unit are used to push the two side pressing blocks closer to each other as the crimping plate is pressed down, so that the two side pressing blocks respectively press the left and right sides of the outer peripheral surface of the power cable. However, in such a power cable crimping machine, the cables are loose and easily fall off the wire feeding wheel, and it is not convenient to clean the dust on the cable surface.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that the loose cables are easy to fall off the wire feeding wheel, and it is inconvenient to clean the dust on the surface of the cables. Therefore, it is necessary to improve the existing technology. Utility Model Content
