Description

Technical Field

[0001] This utility model relates to mechanical equipment, specifically to a cutting device for processing wires and cables. Background Technology

[0002] In the production and subsequent processing of cables and wires, the sheathing process is one of the key steps. It is mainly used to remove the outer insulation from the ends or middle sections of cables and wires to facilitate conductor connection, joint fabrication, or insulation replacement. Currently, commonly used sheathing equipment in the industry suffers from the following problems: Low cutting precision and poor cut quality: Traditional cutting equipment mostly adopts a single-blade unidirectional cutting structure. During the cutting process, the insulation outer sheath is prone to skewed cuts, severe burrs, or even damage to the internal conductor due to unstable fixing of the cable or wire or deviation of the blade movement, affecting the quality of subsequent connections. When switching between different diameter cables and wires, some equipment requires the entire blade assembly to be replaced, which is cumbersome to adjust and has poor adaptability. Debris removal is difficult and pollutes equipment and the environment: Insulation sheath debris and powder generated during the sheathing process easily accumulate at the cutting station, guide rail gaps, and cable surface, which not only pollutes the working environment but also increases the wear of moving parts of the equipment, reduces the service life of the equipment, and manual cleaning requires machine shutdown, affecting processing efficiency. Insufficient flexibility in position adjustment: The cutting stations of existing equipment are mostly fixed structures, which can only realize the cutting operation in a single position. When it is necessary to cut the cable of different lengths or sections, the cable must be moved manually and repositioned. The operation is time-consuming and the positioning accuracy is low, which makes it difficult to meet the needs of mass standardized production. Safety and stability are inadequate: Some peeling equipment lacks effective stroke limit and protective structure, and excessive blade movement can easily lead to equipment collision or operator injury; at the same time, the equipment's center of gravity shifts during the cutting process, which can cause shaking and further reduce the peeling accuracy. In view of the shortcomings of the existing technology, there is an urgent need to design a special cable and wire cutting equipment with high cutting accuracy, timely debris removal, flexible position adjustment and stable operation.

[0022] Example 2: The following is the working principle of the cutting equipment of this utility model: I. Initial state of the equipment and preparations before cutting: After the equipment is powered on and started, each power mechanism is in the initial reset state.

[0023] X-axis power mechanism: The drive shaft of X-axis cylinder 4 is in a retracted state, which drives the movable frame assembly, including movable base 18, upright plate 8, and counterweight stabilizing block 20, to stay at the initial end of X-axis double guide rail 19; Z-axis power mechanism: The first drive shaft 15 of the first Z-axis power mechanism, the lower Z-axis cylinder 17, retracts, so that the lower cutter assembly, including the lower cutter mounting bracket 13 and the lower cutter 14, is located at the lower end of the Z-axis double guide rail 23; the second drive shaft 10 of the second Z-axis power mechanism, the second Z-axis cylinder 9, retracts, so that the upper cutter assembly, including the upper cutter mounting bracket 11 and the upper cutter 12, is located at the upper end of the Z-axis double guide rail 23, at which time the upper cutter 12 and the lower cutter 14 are at the maximum distance. Negative pressure device: The negative pressure device 7 is powered on and ready to be activated. Its negative pressure port is directly opposite the cutting point between the upper cutter 12 and the lower cutter 14, ready to start suction of chips at any time. Meanwhile, operators can check and adjust the limiting structure in advance according to the specifications of the wires and cables to be cut, such as diameter and insulation thickness: by turning the first adjusting nut on the X-axis guide rod 3, the drive shaft stroke of the X-axis cylinder 4 is set; by turning the second adjusting nut on the limiting rod 22, the drive shaft stroke of the lower Z-axis cylinder 17 is set, ensuring that subsequent movements are precise and controllable. II. X-axis movement for cutting position adjustment: When the cutting position needs to be adjusted according to processing requirements, the X-axis power mechanism and the X-axis double guide rail 19 work together to achieve position adjustment.

[0024] Power output: After receiving the control signal, the X-axis cylinder 4 extends or retracts along the X-axis direction. Its drive end is connected to the counterweight stabilizing block 20, which in turn drives the entire movable frame assembly to slide along the X-axis double guide rail 19 on the base plate 1. Smooth guidance and limiting: The X-axis double guide rail 19 is connected to the movable base 18 through the slider, providing smooth guidance for the movable frame assembly and avoiding deviation during movement; at the same time, the X-axis limiting structure plays a role. The two X-axis guide rods 3 move synchronously with the counterweight stabilizing block 20. When the first adjusting nut contacts the vertical plate 5 or the first limiting cap contacts the vertical plate 5, the X-axis cylinder 4 drives the shaft to stop moving. At this time, the movable frame assembly reaches the preset cutting position, ensuring the position adjustment accuracy. Center of gravity balance: The counterweight stabilizing block 20 on the movable base 18 forms a center of gravity balance with the upright plate 8 and the cutter assembly, which prevents the movable frame assembly from shaking due to the center of gravity shift during the X-axis movement, and further improves the stability of position adjustment. III. Cutting execution Z-axis direction cutting motion: After the wire and cable are delivered to the cutting point between the upper cutting blade 12 and the lower cutting blade 14, the cutting action is completed by the synchronous movement of the upper and lower cutting blade assemblies.

[0025] Synchronous power output: The lower Z-axis cylinder 17 and the second Z-axis cylinder 9 receive the cutting signal at the same time. The first drive shaft 15 of the lower Z-axis cylinder 17 extends upward, and the second drive shaft 10 of the second Z-axis cylinder 9 extends downward. Lower cutter assembly: The lower round block at the end of the first drive shaft 15 is engaged with the first T-slot at the lower end of the lower cutter mounting bracket 13, driving the lower cutter mounting bracket 13 to slide upward along the Z-axis double guide rail 23, thereby driving the lower cutter 14 to move upward; Upper cutter assembly: The upper round block at the lower end of the second drive shaft 10 is engaged with the second T-slot at the upper end of the upper cutter mounting bracket 11, driving the upper cutter mounting bracket 11 to slide downward along the Z-axis double guide rail 23, thereby driving the upper cutter 12 to move downward; Since the upper and lower cutting blade assemblies share the same set of Z-axis dual guide rails 23, the parallelism of the movement of the upper cutting blade 12 and the lower cutting blade 14 can be strictly guaranteed, avoiding skewing of the cut due to guide rail deviation. The upper cutter 12 and the lower cutter 14 move towards each other along the Z-axis and finally engage precisely, cutting the insulation of the wire or cable located between them. The X-axis power mechanism pulls back to detach the cut insulation from the wire or cable, exposing the wire core.

[0026] Simultaneously with the cutting action, the negative pressure device 7 is activated, with its negative pressure port directly facing the cutting points of the upper cutter 12 and the lower cutter 14. The filaments produced during the cutting process are directly sucked into the collection chamber of the negative pressure device 7 under the action of negative pressure suction, preventing debris from accumulating around the cutting points.

[0027] IV. After the cutting is completed, each mechanism is reset in sequence and the cycle continues.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
