Description

Technical Field

[0001] This application relates to the technical field of wire processing, and in particular to a dual-blade switching feed mechanism. Background Technology

[0002] In fields such as electronic wire harness processing and communication cable processing, wire cutting and stripping (removing the outer insulation layer) are core technological processes.

[0003] Traditional equipment typically uses separate cutting and stripping blades to complete the corresponding processes. For example, the wire is first cut to a predetermined length using a cutting device, and then the cut wire segments are sent to a stripping device to remove the outer insulation layer. This method is time-consuming and labor-intensive. Furthermore, since the wire needs to be repositioned after handling, some current equipment integrates the cutting and stripping devices into the same unit. After cutting, the wire is moved by a conveyor to the stripping device for stripping. This method, however, leaves at least a section of wire between the cutting and stripping devices, resulting in bulky equipment with a loose layout. Moreover, during long-distance wire transport, errors may accumulate, affecting processing accuracy. Utility Model Content

[0004] To accurately cut and strip wires, this application provides a dual-blade switching feed mechanism.

[0005] This application provides a dual-blade switching feed mechanism, which adopts the following technical solution:

[0006] A dual-blade switching feed mechanism includes a first mounting base, a second mounting base, a tangent blade assembly, a peeling blade assembly, a dual-blade control assembly, and a dual-blade switching assembly;

[0007] The wire cutting knife group and the stripping knife group are disposed on the second mounting base, and the wire cutting knife group and the stripping knife group are spaced apart on the same straight line. The wire cutting knife group includes a first cutting knife and a second cutting knife with the blades facing each other. The stripping knife group includes a third cutting knife and a fourth cutting knife with the blades facing each other. The third cutting knife and the fourth cutting knife are each provided with a receiving groove for accommodating the inner core of the wire.

[0008] The dual-blade control assembly is disposed on the second mounting base. The dual-blade control assembly can control the first cutter and the second cutter to move away from each other or towards each other. The dual-blade control assembly can also control the third cutter and the fourth cutter to move away from each other or towards each other.

[0009] The second mounting base is slidably disposed on the first mounting base, and the dual-blade switching component can drive the second mounting base to slide back and forth, thereby moving the cutting edge of the wire cutting blade group or the stripping blade group to the position where the wire passes through.

[0010] By adopting the above technical solution, the wire cutting blade group and the stripping blade group are rationally integrated into one unit, and the wire cutting blade group and the stripping blade group are quickly and accurately switched with the help of a dual-blade control component. This enables rapid cutting or stripping of wires, reducing the complexity and floor space of the equipment and improving work efficiency. At the same time, by using the dual-blade control component to control the wire cutting blade group and the stripping blade group, both blades can be controlled to work simultaneously with a single power source, which can further simplify the equipment and improve the utilization rate of the power source.

[0011] Optionally, the dual-blade switching assembly includes an adjustment plate, a cam, and a first power component. The adjustment plate is mounted on the second mounting base, and the first power component is mounted on the first mounting base. The first power component can drive the cam to move up and down. The adjustment plate has a cam groove for the cam to insert into and slide. The cam groove includes a first groove, a second groove, and a third groove connected between the first and second grooves, which are spaced apart along the horizontal direction. The first and second grooves extend vertically, and the third groove extends upward at an incline toward the second groove. When the cam is located in the first groove, the cutting blade assembly is aligned with the wire movement path. When the cam is located in the second groove, the stripping blade assembly is aligned with the wire movement path.

[0012] By adopting the above technical solution, the coordination of the adjusting plate, cam and the first power component realizes the reciprocating sliding of the second mounting base, thereby driving the cutting edge of the wire cutting knife group or stripping knife group to the position where the wire passes through. This design utilizes the multi-segment structure of the cam groove to realize the precise switching of the knife group, ensuring that the knife group can accurately align with the wire movement path under different working conditions, thereby improving the reliability and operating accuracy of the equipment.

[0013] Optionally, the first power component includes a cylinder disposed on the first mounting base and a power plate connected to the end of the cylinder telescopic shaft, the cam being connected to the power plate, and the cylinder telescopic shaft extending in a vertical direction.

[0014] By adopting the above technical solution, using a cylinder as the primary power component, and driving the cam to move up and down through a power plate, the power output of the cylinder is stable and easy to control, enabling fast and precise tool switching actions.

[0015] Optionally, the first power component further includes a first limiting slider disposed on the power plate, a first limiting guide rail disposed on the first mounting base along the vertical direction, and the first limiting slider sliding up and down on the first limiting guide rail; a second limiting guide rail disposed on the first mounting base along the horizontal direction, and a second limiting slider disposed on the second mounting base, and the second limiting slider sliding on the second limiting guide rail.

[0016] By adopting the above technical solution, the first limiting slider and the first limiting guide rail, as well as the second limiting slider and the second limiting guide rail, limit the movement of the power plate and the second mounting base; this limiting design can effectively prevent the moving parts from deviating or shaking during operation, ensure the stability and accuracy of the equipment, and extend the service life of the equipment.

[0017] Optionally, the second mounting base has two positioning plates spaced apart vertically. The two positioning plates have positioning grooves on their sides that are close to each other to accommodate the adjusting plate. The positioning grooves extend horizontally along the length of the positioning plates. The positioning plates are provided with a plurality of fixing bolts for fixing the adjusting plate. The positioning plates have waist-shaped grooves for the fixing bolts to pass through. The waist-shaped grooves extend along the length of the positioning plates. The adjusting plates also have fixing holes for the fixing bolts to be threaded through. The fixing bolts can pass through the waist-shaped grooves and the fixing holes in sequence.

[0018] By adopting the above technical solution, the positioning plate and fixing bolts work together to detachably fix the adjusting plate to the second mounting base; the design of the waist-shaped groove on the positioning plate makes the installation and adjustment of the adjusting plate more flexible, and can be finely adjusted according to actual needs, thereby improving the adaptability and adjustability of the equipment.

[0019] Optionally, the second mounting base is further provided with a first positioning block, and the first positioning block is provided with a positioning bolt. The positioning bolt is threaded through the first positioning block and the end face of the positioning bolt can abut against the side wall of the adjusting plate.

[0020] By adopting the above technical solution and setting the first positioning block and positioning bolt, the fixing stability of the adjustment plate is further enhanced.

[0021] Optionally, the second mounting base is further provided with a second positioning block, and an adjusting bolt is rotatably provided on the second positioning block. The end of the adjusting bolt is threadedly connected to the adjusting plate, and an adjusting groove is provided on the side wall of the adjusting plate for the adjusting bolt to be threadedly connected.

[0022] By adopting the above technical solution and setting a second positioning block and adjusting bolt, the fine-tuning function of the adjusting plate is realized; the threaded connection design between the adjusting bolt and the adjusting plate allows the position of the adjusting plate to be precisely adjusted as needed, further improving the accuracy and adaptability of the equipment.

[0023] Optionally, the dual-blade control assembly includes a bidirectional screw rotatably mounted on the second mounting base, an upper control plate and a lower control plate slidably mounted on the second mounting base, and a second power component for driving the bidirectional screw to rotate. The bidirectional screw has opposite threads, a forward thread and a reverse thread, on its two end sidewalls. The upper control plate and the lower control plate are threadedly connected to the forward thread and the reverse thread, respectively. The first cutter and the second cutter are respectively mounted on the upper control plate and the lower control plate, and the third cutter and the fourth cutter are also respectively mounted on the upper control plate and the lower control plate.

[0024] By adopting the above technical solution, the cooperation of the bidirectional screw, upper control board, and lower control board enables the movement control of the blades in the tangent and peeling blade groups. The forward and reverse thread design of the bidirectional screw allows the blades to move in directions that are either far apart or close to each other, thereby achieving precise cutting and peeling operations. This design improves the flexibility and processing accuracy of the equipment.

[0025] Optionally, a third limiting guide rail is provided on the second mounting base along the vertical direction, and a third limiting slider and a fourth limiting slider are respectively provided on the upper control plate and the lower control plate. The third limiting slider and the fourth limiting slider are both slidably disposed on the third limiting guide rail.

[0026] By adopting the above technical solution, a third limit guide rail, a third limit slider, and a fourth limit slider are set to limit the movement of the upper and lower control plates. This limit design can effectively prevent the control plates from deviating during operation, ensure the movement accuracy and stability of the blades, and further improve the processing quality of the equipment.

[0027] Optionally, the first cutter is detachably fixed to the upper control plate by several bolts, and the upper control plate has a slot for the first cutter to engage, the slot extending downward to the lower surface of the upper control plate.

[0028] By adopting the above technical solution, a slot is set on the control board to hold the blade, and the blade is designed to be detachable, which facilitates the replacement and maintenance of the blade. At the same time, the slot design can ensure the installation accuracy of the blade, improve the service life of the equipment and processing efficiency.

[0029] In summary, this application includes at least one of the following beneficial effects:

[0030] 1. This dual-blade switching feed mechanism integrates wire cutting and stripping functions, enabling wire cutting and stripping operations to be completed in one device, reducing the equipment's footprint, lowering equipment costs, and improving work efficiency.

[0031] 2. Through the multi-segment structure of the cam groove, the cooperation of the limiting guide rail and the slider, and the precise control of the bidirectional screw, this mechanism can achieve precise switching of the tool set and precise movement of the blade; this high-precision design ensures the quality and stability of wire processing, avoids damage to the wire core, and improves the reliability and service life of the equipment.

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0041] This application discloses a dual-blade switching feed mechanism, referring to... Figure 1 and Figure 2 The dual-blade switching feed mechanism includes a first mounting base 1, a second mounting base 2, a tangent blade assembly 3, a peeling blade assembly 4, a dual-blade control component 5, and a dual-blade switching component 6. The second mounting base 2 is slidably mounted on the first mounting base 1, as shown in the reference... Figure 3 Both the wire cutting blade assembly 3 and the stripping blade assembly 4 are mounted on the second mounting base 2. The dual-blade switching assembly 6 can alternately move the wire cutting blade assembly 3 or the stripping blade assembly 4 onto the movement path of the wire, so that the wire can pass through the wire cutting blade assembly 3 for cutting, or pass through the stripping blade assembly 4 to strip the outer insulation layer of the wire. The dual-blade control assembly 5 can control the wire cutting blade assembly 3 or the stripping blade assembly 4 to cut.

[0042] Reference Figure 1 and Figure 2 The tangent blade assembly 3 and the peeling blade assembly 4 are spaced apart along the same straight line on the second mounting base 2. They can be arranged along any straight line according to the actual equipment space requirements, with the two spaced apart on the same straight line. The corresponding dual-blade switching assembly 6 can move the tangent blade assembly 3 and the peeling blade assembly 4 along this straight line to switch between them. In this embodiment, using... Figure 2 The orientation is used as a reference. The wire cutting knife group 3 and the stripping knife group 4 are arranged at intervals along the horizontal direction. The wire cutting knife group 3 and the stripping knife group 4 can move left and right under the control of the double knife switching component 6, so that the cutting edge of the wire cutting knife group 3 or the stripping knife group 4 can accurately reach the required processing position of the wire, achieving a highly efficient and precise operation effect.

[0043] Reference Figure 2 and Figure 3 In this embodiment, specifically, the first mounting base 1 is fixed in the entire wire processing equipment, serving a supporting function. The dual-blade switching assembly 6 can control the second mounting base 2 to slide left and right on the first mounting base 1, thereby switching between the wire cutting blade group 3 and the stripping blade group 4. The dual-blade switching assembly 6 includes an adjusting plate 61, a cam 62, and a first power component 63; wherein, the adjusting plate 61 is preferably configured as a rectangular plate, which is fixed to one side wall of the second mounting base 2. The first power component 63 is disposed on the first mounting base 1 and can drive the cam 62 to move up and down. The adjusting plate 61 has a cam groove 611 for the cam 62 to insert and slide, as shown in the figure. Figure 4The cam groove 611 includes a first groove 6111 and a second groove 6112 spaced apart in the horizontal direction, and a third groove 6113 connecting the two. The first groove 6111 and the second groove 6112 both extend in the vertical direction, and the third groove 6113 extends upward at an incline toward the second groove 6112, so that the overall cam groove 611 is S-shaped.

[0044] Reference Figure 2 and Figure 5 ,by Figure 2 With the orientation as a reference, at this time, the first groove 6111 is located on the left side, and the second groove 6112 is located on the right side; at the same time, the tangent knife assembly 3 is located on the left side, and the peeling knife assembly 4 is located on the right side. When the cam 62 is located in the first groove 6111 (refer to...), Figure 5 The wire cutter assembly 3 is located on the wire movement path and can cut the wire; when the cam 62 moves upward under the drive of the first power member 63, it can drive the cam 62 to slide along the third groove 6113 into the second groove 6112. At this time, the adjusting plate 61 moves relative to the cam 62. When the cam 62 is in the second groove 6112 (refer to...). Figure 2 The stripping blade assembly 4 is aligned with the moving position of the wire and can strip the wire.

[0045] It should be noted that the transitions between the first groove 6111 and the third groove 6113, as well as the transitions between the third groove 6113 and the second groove 6112, are all designed as arc-shaped sections to ensure a smooth and stable blade switching process. Simultaneously, the first groove 6111 and the second groove 6112 are respectively located at both ends of the third groove 6113. This allows the tangent blade group 3 or the peeling blade group 4 to move to a preset position when the protrusion slides into the first groove 6111 or the second groove 6112. This design improves the accuracy of positioning the tangent blade group 3 and the peeling blade group 4, ensuring stable equipment operation.

[0046] Reference Figure 2 and Figure 3The first power component 63 includes a cylinder 631 disposed on the first mounting base 1 and a power plate 632 connected to the end of the telescopic shaft of the cylinder 631. The telescopic shaft of the cylinder 631 extends in a vertical direction. A cam 62 is connected to the power plate 632. Preferably, the cam 62 can be rotatably connected so that the cam 62 moves more smoothly in the cam groove 611. In addition, the first power component 63 also includes a first limiting slider 633 disposed on the power plate 632. The power plate 632 extends horizontally, and the first limiting slider can be disposed at the left and right ends of the power plate 632 respectively. A first limiting guide rail 11 is disposed vertically on the first mounting base 1, and the first limiting guide rail 11 and the first limiting slider 633 are disposed in a one-to-one correspondence. The first limiting slider 633 is engaged with the first limiting guide rail 11 and can move up and down along the first limiting guide rail 11. At the same time, a second limiting guide rail 13 is disposed horizontally on the side of the first mounting base 1 facing the second mounting base 2, and a second limiting slider 25 is disposed on the second mounting base 2. The second limiting slider 25 is slidably engaged with the second limiting guide rail 13 and can slide along the second limiting guide rail 13, thereby increasing the stability of the operation of the double-blade switching component 6. In this embodiment, in order to facilitate the fixing of the first limiting guide rail 11, a back plate 12 is detachably fixed on the first mounting base 1, and the first limiting guide rail 11 is disposed on the back plate 12.

[0047] Reference Figure 3 and Figure 4 In an optional embodiment, to facilitate the adjustment of the position of the adjusting plate 61 and ensure the cutting accuracy of the wire, the adjusting plate 61 can be configured as a detachable and fixed structure. Specifically, two positioning plates 21 are also provided on the side wall of the second mounting base 2 facing the first mounting base 1. Both positioning plates 21 can be rectangular plates, and they are spaced apart along the vertical direction. The two positioning plates 21 can be fixed to the second mounting base 2 by bolts or other means. Positioning grooves 211 for accommodating the adjusting plate 61 are opened on their adjacent sides. The positioning grooves 211 extend horizontally along the length of the positioning plate 21, so that the adjusting plate 61 can slide left and right in the positioning grooves 211. The positioning plate 21 is provided with several fixing bolts 212 for fixing the adjusting plate 61. The positioning plate 21 has a slotted groove 213 for the fixing bolts 212 to pass through, extending along the length of the positioning plate 21. The adjusting plate 61 has a fixing hole for the fixing bolts 212 to be threaded through. The fixing bolts 212 can pass through the slotted groove 213 and the fixing hole in sequence. This structure allows the adjusting plate 61 to be adjusted left and right within a certain range.

[0048] Reference Figure 3 and Figure 4Furthermore, preferably, a first positioning block 22 is fixed to one side wall of the second mounting base 2. A positioning bolt 221 is provided on the first positioning block 22. The positioning bolt 221 is threaded through the first positioning block 22 in a horizontal direction, and its end face can abut against the side wall of the adjusting plate 61. Thus, when the adjusting plate 61 is fixed, the first positioning block 22, by abutting against the side wall of the adjusting plate 61, can further improve the stability of the adjusting plate 61. Furthermore, a second positioning block 23 is also fixed to the second mounting base 2. An adjusting bolt 231 is rotatably mounted on the second positioning block 23. The end of the adjusting bolt 231 passes through the second positioning block 23 and is threaded onto the adjusting plate 61. An adjusting groove is provided on the side wall of the adjusting plate 61 for threaded connection of the adjusting bolt 231. When it is necessary to change the position of the adjusting plate 61, simply rotating the adjusting bolt 231 will move the adjusting plate 61. This adjustment method is more precise, thereby further ensuring the accuracy of the equipment and improving the quality of wire processing.

[0049] Reference Figure 6 and Figure 7 In this embodiment, the wire cutting knife group 3 consists of a first cutter 31 and a second cutter 32 with their blades facing each other. The blades of the first cutter 31 and the second cutter 32 are preferably V-shaped to accommodate wires of different sizes. The stripping knife group 4 consists of a third cutter 41 and a fourth cutter 42 with their blades facing each other. The blades of the third cutter 41 and the fourth cutter 42 can also be V-shaped. Both the third cutter 41 and the fourth cutter 42 have a receiving groove for accommodating the inner core of the wire. The receiving groove is semi-circular. When the third cutter 41 and the fourth cutter 42 approach each other, the two receiving grooves form a complete circle, which is used to accommodate the inner core of the wire. The dual-blade control component 5 can control the two sets of cutters to move in directions that move away from or towards each other, thereby controlling the wire cutting knife group 3 to cut the wire, or controlling the stripping knife group 4 to strip the wire. Meanwhile, both the wire cutting knife group 3 and the stripping knife group 4 are mounted on the second mounting base 2. Through the cooperation of the cam 62 and the cam groove 611, the second mounting base 2 can slide, so that the cutting edge of the wire cutting knife group 3 or the stripping knife group 4 can accurately reach the required processing position of the wire, achieving a highly efficient and precise operation effect.

[0050] Reference Figure 1 and Figure 7In this embodiment, the dual-blade control assembly 5 includes a bidirectional screw 51 rotatably mounted on the second mounting base 2, an upper control plate 52 and a lower control plate 53 slidably mounted on the second mounting base 2, and a second power component 54 for driving the bidirectional screw 51 to rotate. The bidirectional screw 51 is arranged vertically, and its upper and lower end sidewalls are provided with opposite threads: a forward thread and a reverse thread. The upper control plate 52 and the lower control plate 53 are threadedly connected to the forward thread and the reverse thread, respectively. Specifically, to ensure stability, two seats can be fixedly connected to the sidewalls of the upper control plate 52 and the lower control plate 53. The bidirectional screw 51 is threadedly engaged with the two seats, thereby driving the upper control plate 52 and the lower control plate 53 through the seats.

[0051] Furthermore, to ensure stable operation, a third limiting guide rail 24 is vertically mounted on the second mounting base 2. A third limiting slider 521 and a fourth limiting slider 531 are respectively mounted on the upper control plate 52 and lower control plate 53. Both sliders are engaged and slide vertically on the third limiting guide rail 24, thus ensuring that the upper control plate 52 and lower control plate 53 can move stably up and down when the bidirectional screw 51 rotates. Similarly, multiple third limiting guide rails 24 can be provided to further improve stability.

[0052] In an optional embodiment, the second power component 54 includes a motor, a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The motor is fixed to the second mounting base 2 by bolts or other means. The first synchronous pulley is coaxially connected to the output end of the motor. The second synchronous pulley is coaxially connected to the bidirectional screw 51. The synchronous belt passes around the first and second synchronous pulleys, so that when the motor starts, it can drive the bidirectional screw 51 to rotate.

[0053] Reference Figure 6 and Figure 7 In this embodiment, the first cutter 31 and the third cutter 41 are spaced apart on the upper control plate 52, and the second cutter 32 and the fourth cutter 42 are spaced apart on the lower control plate 53. Thus, when the upper control plate 52 and the lower control plate 53 are separated, the wire cutting knife group 3 and the stripping knife group 4 can be opened to allow the wire to pass through. When the upper control plate 52 and the lower control plate are close to each other, the wire cutting knife group 3 or the stripping knife group 4 can cut or strip the wire. To accommodate more types of wire, both the wire cutting knife group 3 and the stripping knife group 4 can be detachably installed. In this embodiment, the first cutter 31, the second cutter 32, the third cutter 41, and the fourth cutter 42 are all the same size and have the same fixing method, differing only in their blade designs. The following explanation uses the fixing method of the first cutter 31 as an example.

[0054] Specifically, the blade body of the first cutter 31 can be a rectangular sheet structure. The upper control plate 52 has a slot 522 for the first cutter 31 to engage. The slot 522 extends downwards to the lower surface of the control plate. After the first cutter 31 is initially positioned by the slot 522, it is detachably fixed to the upper control plate 52 by multiple bolts. This detachable fixing method facilitates the replacement and maintenance of the cutter, or the replacement with cutters of different blade edges to adapt to different types of wires.

[0055] The implementation principle of the dual-blade switching feed mechanism in this application embodiment is as follows: In use, the wire is first moved forward a predetermined distance by the conveying device in the equipment. Then, the motor is started to drive the bidirectional screw 51 to rotate, which drives the first cutter 31 and the second cutter 32 to move closer to each other to cut the wire. Then, the conveying device moves the wire a certain distance and starts the cylinder 631 to drive the cam 62 to slide along the cam groove 611, so that the wire cutting blade group 3 is switched to the stripping blade group 4 for use. Then, the motor is started again to drive the third cutter 41 and the fourth cutter 42 to move closer to each other to strip the wire.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
