Description

Technical fields:

[0001] This utility model relates to the field of core wire processing technology, and specifically to a semi-automatic core wire cutting device. Background technology:

[0002] Traditional core wire cutting methods have many shortcomings in core wire processing. Especially when cutting core wires containing yellow denier filaments, the high toughness and strength of these filaments make it difficult to completely cut them using conventional cutting tools such as scissors or ordinary cutting machines, often resulting in uncut filaments. This incomplete cutting leads to a decrease in core wire processing quality, affecting subsequent assembly and use, increasing processing and time costs, and reducing production efficiency. This is detrimental to the high-efficiency production requirements of the cable processing industry. Therefore, dedicated core wire cutting equipment is generally used in the market.

[0003] Currently available cutting equipment can ensure neat core wire cuts. For example, Chinese utility model patent application CN212917417U discloses a cutting device for core wire processing, which includes: an operating table, a first cylinder fixed on the operating table, a first piston rod on the first cylinder, an extension plate fixed on the first piston rod, a support base between the two extension plates, a motor fixed in the groove of the support base via a bracket, a drive shaft fixed to the motor shaft via a coupling, a cutting disc fixed on the drive shaft, a bearing with an interference fit to the drive shaft fixed to the support base via a bracket, and an internal hole on the operating table through which the cutting disc passes. Cutting by rotating the cutting disc is more convenient than using a blade, and the cut core wire is cut more neatly without damage to the surrounding area. Furthermore, a pressure plate can tighten and clamp the core wire during cutting.

[0004] However, this existing cutting equipment still has the following shortcomings:

[0005] When using this device, the operator needs to manually push the core wire to be cut towards the center of the device. This method is prone to pulling the operator's hand into the work area due to the inertia of the mechanical movement, causing danger. In addition, the work efficiency is low, and it is not convenient to adjust when cutting core wires of different diameters and lengths, resulting in poor applicability.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a semi-automatic core wire cutting device.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a semi-automatic core wire cutting device, comprising: a base, a cutting structure disposed on the base for cutting the core wire, and a guide structure disposed on the base for conveying the core wire; the cutting structure includes a cylinder fixing bracket disposed at one end of the base, a first driving cylinder mounted on the cylinder fixing bracket, a sliding blade holder connected to the output shaft of the first driving cylinder and driven by the first driving cylinder to slide up and down, a first blade disposed on the sliding blade holder for cutting the core wire, and a second blade disposed on the base for cooperating with the first blade for cutting; the guide structure includes a fixing block disposed on the base, a positioning plate slidably disposed on the fixing block for carrying and positioning the core wire, and a first limiting bolt for limiting the positioning plate on the fixing block.

[0009] Furthermore, in the above technical solution, a positioning hole is provided on the fixing block, and correspondingly, a strip hole is provided on the positioning plate. The positioning plate also has a stepped groove at the strip hole. The first limiting bolt passes through the strip hole and is inserted into the positioning hole. The bolt cap of the first limiting bolt is slidably engaged in the stepped groove so that the positioning plate can slide back and forth along the strip hole.

[0010] Furthermore, in the above technical solution, the positioning plate has several protruding limiting protrusions to prevent the core wire from accidentally slipping off; the fixing block has a recessed guide groove to limit the positioning plate, so as to prevent the positioning plate from accidentally swinging when sliding.

[0011] Furthermore, in the above technical solution, the base has a waste hole for discharging waste material below the cylinder fixing frame, and the base is also provided with a second blade holder for fixing the second blade. The second blade holder has a discharge slope formed on it, and the discharge slope faces the waste hole so that the core wire can slide down the discharge slope to the waste hole.

[0012] Furthermore, in the above technical solution, the upper end of the cylinder fixing bracket is formed with a slide rail for the sliding tool holder to move up and down, and the cylinder fixing bracket is respectively equipped with a first pressure block and a second pressure block on both sides of the slide rail for axially limiting the sliding tool holder within the slide rail.

[0013] Furthermore, in the above technical solution, the sliding blade holder is provided with a fixing plate for clamping and fixing the first blade, and the blade edge of the first blade is distributed at an angle.

[0014] Furthermore, in the above technical solution, the base is recessed and formed with a mounting groove for accommodating the cylinder mounting bracket; four foot pads are provided below the base for providing support.

[0015] Furthermore, in the above technical solution, the base is recessed with a groove for accommodating the fixing block, and the fixing block is adjustablely disposed in the groove to adapt to cutting core wires of different lengths.

[0016] Furthermore, in the above technical solution, a controller for controlling the device is provided on the back of the cylinder mounting bracket; a pressure regulating valve for adjusting the air pressure in the first drive cylinder is also provided on the back of the cylinder mounting bracket.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the present invention, the guide structure, by slidably setting the positioning plate on the fixed block, effectively enables the guide structure and the cutting structure to work together to cut the core wire, eliminating the need for operators to manually push the core wire, effectively reducing operational risks. Furthermore, compared with manual wire feeding, the guide structure is more efficient and has better cutting accuracy, making it suitable for widespread application in various wire cutting equipment. In addition, compared with the existing structure, the present invention, by adjusting the fixed block to the base 1, adapts to cutting core wires of different lengths, and the structure is simpler and more compact.

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figures 1 to 5As shown, a semi-automatic core wire cutting device includes: a base 1, a cutting structure 20 disposed on the base 1 for cutting the core wire, and a guide structure 7 disposed on the base 1 for conveying the core wire; the cutting structure 20 includes a cylinder fixing frame 2 disposed at one end of the base 1, a first drive cylinder 3 mounted on the cylinder fixing frame 2, a sliding blade holder 4 connected to the output shaft of the first drive cylinder 3 and driven by the first drive cylinder 3 to slide up and down, a first blade 5 disposed on the sliding blade holder 4 for cutting the core wire, and a second blade 6 disposed on the base 1 for cooperating with the first blade 5 for cutting; the guide structure 7 includes a fixing block 71 disposed on the base 1, a positioning plate 72 slidably disposed on the fixing block 71 for carrying and positioning the core wire, and a first limiting bolt 73 for limiting the positioning plate 72 on the fixing block 71.

[0025] In this invention, the guide structure 7, by slidably mounting the positioning plate 72 onto the fixing block 71, effectively enables the guide structure 7 and the cutting structure 20 to work together to cut the core wire, eliminating the need for manual pushing of the core wire by the operator, thus effectively reducing operational risks. Furthermore, compared to manual wire feeding, the guide structure 7 is more efficient and has better cutting accuracy, making it suitable for widespread application in various wire cutting equipment. In addition, compared to existing structures, this invention, by adjusting the fixing block 71 onto the base 1, adapts to cutting core wires of different lengths, and its structure is simpler and more compact.

[0026] In this embodiment, to avoid using human hands to push the core wire, a guide structure 7 is used instead of human hands to move the core wire toward the cutting structure 20. Specifically, a positioning hole 711 is provided on the fixing block 71, and correspondingly, a strip hole 721 is provided on the positioning plate 72. The positioning plate 72 also has a stepped groove 722 at the strip hole 721. The first limiting bolt 73 passes through the strip hole 721 and is inserted into the positioning hole 711. The bolt cap 731 of the first limiting bolt 73 is slidably engaged in the stepped groove 722, so that the positioning plate 72 can slide back and forth along the strip hole 721. Preferably, the positioning plate 72 has a strip-shaped hole 721 opened along the long axis, and the positioning plate 72 is fixed to the fixing block 71 by the first limiting bolt 73, so that the positioning plate 72 can slide along the long axis. When cutting, the positioning plate 72 is first manually pulled outward to move the positioning plate 72 away from the cutting work area. Then, the core wire is placed on the positioning plate 72, and the end of the positioning plate 72 is manually pushed away from the cutting structure 20 to send the core wire between the first blade 5 and the second blade 6 of the cutting structure 20 for cutting. This method ensures a safe distance between the human hand and the cutting structure 20, which can effectively reduce the risk of the hand being brought into the cutting work area.

[0027] The positioning plate 72 has several protruding limiting protrusions 723 to prevent the core wire from accidentally slipping off; the fixing block 71 has a recessed guide groove 712 to limit the positioning plate 72, so as to prevent the positioning plate 72 from accidentally swinging during sliding. Here, the limiting protrusions 723 are located at the corners of the positioning plate 72, thereby limiting the core wire and effectively preventing the core wire from accidentally falling off during cutting due to the force of the first blade 5 and the second blade 6.

[0028] The base 1 has a waste hole 110 for discharging waste material below the cylinder mounting bracket 2. The base 1 also has a second blade holder 120 for fixing the second blade 6. The second blade holder 120 has a discharge ramp 121 formed on it, facing the waste hole 110, so that the core wire can slide down the discharge ramp 121 into the waste hole 110. Here, the waste material generated during the cutting process slides down the discharge ramp 121 into the waste hole 110. It is understood that a waste collection frame can also be set below the waste hole 110, and regular cleaning of the waste collection frame can effectively maintain a clean working environment.

[0029] The upper end of the cylinder mounting bracket 2 is formed with a slide rail 201 for the sliding blade holder 4 to slide up and down. A first pressure block 202 and a second pressure block 203 are respectively installed on both sides of the slide rail 201 to axially limit the sliding blade holder 4 within the slide rail 201. Here, the first pressure block 202 and the second pressure block 203 are fixed to the upper end of the cylinder mounting bracket 2, effectively confining the sliding blade holder 4 within the slide rail 201, ensuring that the first blade 5 slides up and down strictly according to the slide rail 201, thus guaranteeing cutting accuracy.

[0030] The sliding blade holder 4 is equipped with a clamping plate 41 for clamping and fixing the first blade 5, and the cutting edges of the first blade 5 are distributed at an angle. Here, the angled distribution of the cutting edges of the first blade 5 can effectively reduce the load on the first blade 5 during cutting, resulting in more uniform force distribution, less likelihood of chipping, and a smoother cut. In addition, preferably, both the first blade 5 and the second blade 6 are made of tungsten steel, which has high strength and high wear resistance.

[0031] The base 1 has a recessed mounting groove 130 for accommodating the cylinder mounting bracket 2; four foot pads 140 are provided below the base 1 for providing support.

[0032] The base 1 has a recessed groove 150 for accommodating the fixing block 71. The fixing block 71 is adjustable within the recessed groove 150 to accommodate core wires of different lengths. The base 1 has multiple through holes 151 arranged within the recessed groove 150. The lower end face of the fixing block 71 has two first screw holes 715. A second screw 122 passes through the first through holes 151 and is screwed into the first screw holes 715, thus fixing the fixing block 71 to the base 1. Furthermore, the relative distance between the fixing block 71 and the cutting mechanism 20 can be adjusted by fitting the second screw 122 into different first through holes 151, thereby accommodating the cutting of core wires of different lengths.

[0033] The cylinder mounting bracket 2 is equipped with a controller 8 for controlling the device on its back; the cylinder mounting bracket 2 is also equipped with a pressure regulating valve 9 for adjusting the air pressure inside the first drive cylinder 3.

[0034] In summary, in this invention, the guide structure 7, by slidably mounting the positioning plate 72 onto the fixing block 71, effectively enables the guide structure 7 and the cutting structure 20 to work together to cut the core wire, eliminating the need for manual pushing of the core wire by the operator, thus effectively reducing operational risks. Furthermore, compared to manual wire feeding, the guide structure 7 is more efficient and has better cutting accuracy, making it suitable for widespread application in various wire cutting equipment. In addition, compared to existing structures, this invention, by adjusting the fixing block 71 onto the base 1 to adapt to cutting core wires of different lengths, also results in a simpler and more compact structure.
