As market demand for braided wire products continues to grow, so too are the requirements for production efficiency, precision, and quality. Many braided wire products need to be cut to specific lengths during the production process to meet the needs of different application scenarios. For example, in the electronics industry, braided wire is often used as a component of internal connecting wires or cables, and the length of these connecting wires or cables must be precisely controlled to ensure they can be properly installed in the equipment.

[0003] Related technology: A wire harness weaving and cutting assembly includes a frame and a punching assembly. A cutting cavity is formed in the frame. The frame has a first panel facing the wire harness. A feed channel is provided on the first panel. The feed channel separates the first panel into a first baffle and a second baffle. The wire harness passes through the feed channel and enters the cutting cavity, and the weaving contacts and fits with the inner surface of the first panel. The punching assembly includes a first punching piece and a second punching piece. The first punching piece and the second punching piece are installed in the cutting cavity so as to be movable forward and backward. The first punching piece is arranged opposite to the first baffle, and the second punching piece is arranged opposite to the second baffle. When the weaving contacts and fits with the inner surface of the first baffle, the first punching piece punches toward the first baffle to cut the weaving. When the weaving contacts and fits with the inner surface of the second baffle, the second punching piece punches forward to cut the remaining weaving. The frame is enclosed by six panels, within which a cutting chamber is formed. The two panels, positioned opposite each other in the front and back, are defined as a first panel and a second panel. The first panel is provided with a feed channel extending vertically through it, separating it into a first baffle and a second baffle. The width of the feed channel is greater than the diameter of the longest braid. The cutting chamber is provided with a first punching member and a second punching member that can move forward and backward. The first punching member is positioned opposite the first baffle, while the second punching member is positioned opposite the second baffle.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are simply used to distinguish different components.

[0035] For ease of understanding, in the horizontal direction of this embodiment, the length direction of the wire is defined as the first direction, and the direction perpendicular to the first direction is defined as the second direction, and the punching and weaving equipment is described based on this.

[0036] The embodiment of the present application discloses a punching and weaving mechanism. Figure 1 The punching and braiding device includes a base 1, a wire clamping mechanism 2, a moving mechanism 3, a clamping mechanism, and a braiding and cutting mechanism 6. The wire clamping mechanism 2 is mounted on the base 1 and is used to clamp and secure the wire to be processed. The moving mechanism 3 is mounted on the base 1 and is used to adjust the position of the cutting mechanism along a first direction according to the type of wire. The clamping mechanism is used to simultaneously clamp and secure multiple wires, and the cutting mechanism is used to cut the braided wires to a standard length.

[0037] Reference Figure 1The base 1 includes a bottom plate 11, a top plate 12, and two support plates 13. The two support plates 13 are parallel to each other. The bottom end of each support plate 13 is fixedly connected to the upper surface of the bottom plate 11, and the top end of each support plate 13 is fixedly connected to the lower surface of the top plate 12. By providing two parallel support plates 13, the base 1 firmly connects the bottom plate 11 and the top plate 12 to form a stable support structure, providing a reliable installation platform for the clamping mechanism 2, the moving mechanism 3, the clamping mechanism, and the weaving and cutting mechanism 6.

[0038] Reference Figure 1 and Figure 2 The moving mechanism 3 includes a sliding seat 31, a support 32 and a first cylinder 33. The sliding seat 31 slides with the top plate 12. The support 32 is fixed on the top plate 12, and the first cylinder 33 is fixed on the support 32. The piston rod of the first cylinder 33 is fixedly connected to the end of the sliding seat 31. When it is necessary to process different types of wires, the piston rod is driven to extend and retract by the first cylinder 33, so as to facilitate driving the sliding seat 31 to move along the second direction, thereby facilitating the clamping mechanism and the weaving and cutting mechanism 6 to move along the second direction at the same time, so as to facilitate the weaving and cutting of a variety of different types of wires. Of course, the first cylinder 33 here can also adopt an electric push rod. The electric push rod has the characteristics of smooth operation and high precision. It can more accurately control the moving distance and speed of the sliding seat 31, and has obvious advantages in occasions where high position accuracy is required.

[0039] Reference Figure 2 A slider 35 is fixedly provided on the lower surface of the sliding seat 31, and a guide rail 15 is fixedly provided on the upper surface of the base 1. The guide rail 15 extends along the first direction, and the guide rail 15 passes through the slider 35. The slider 35 slides with the guide rail 15, thereby increasing the stability of the sliding seat 31 moving along the first direction.

[0040] Reference Figure 1 In this embodiment, there are two clamping mechanisms, both of which are disposed on the sliding seat 31 and spaced apart along the first direction. Each clamping mechanism includes a lifting assembly 4 and a clamping assembly 5. The lifting assembly 4 is disposed on the base 1 and is used to drive the clamping assembly 5 to move upward and downward.

[0041] Continue to refer to Figure 1Furthermore, the lifting assembly 4 includes a lifting seat 41, a bearing seat 42, and a first lifting cylinder 43 for the lifting seat. The bearing seat 42 is fixed to the upper surface of the top plate 12, the bottom end of the first lifting cylinder 43 is fixedly connected to the upper surface of the bearing seat 42, the piston rod of the first lifting cylinder 43 is fixedly connected to the lifting seat 41, and the first lifting cylinder 43 is used to drive the lifting seat 41 to move up and down. The clamping assembly 5 is arranged on the lifting seat 41. When it is necessary to adjust the height of the clamping assembly 5, the first lifting cylinder 43 starts to work, and its piston rod is extended and retracted to drive the lifting seat 41 to move up and down. Since the clamping assembly 5 is arranged on the lifting seat 41, the height of the clamping assembly 5 can be automatically adjusted to adapt to the processing positions of different wires.

[0042] Continue to refer to Figure 1 A guide seat 44 is fixedly provided on the upper surface of the bearing seat 42, and a second guide groove 45 is provided on the top of the guide seat 44. The second guide groove 45 extends in the vertical direction. A first guide block 46 is fixedly provided on the lower surface of the lifting seat 41. The first guide block 46 extends in the vertical direction. The bottom end of the first guide block 46 is inserted into the second guide groove 45. The first guide block 46 and the second guide groove 45 are slidably matched, which increases the stability of the lifting seat 41 and the clamping assembly 5 in lifting and lowering.

[0043] Reference Figure 1 、 Figure 3 and Figure 4 The clamping assembly 5 includes a linkage part 51, a second lifting cylinder 52, a first moving part 53, a second moving part 54, a first clamping part 55 and a second clamping part 56. A lifting groove 47 is provided at the top of the lifting seat 41, and a sliding groove 48 is provided at the bottom end of the lifting seat 41. The sliding groove 48 extends along the first direction, and both ends of the sliding groove 48 are open, and the bottom end of the lifting groove 47 is connected to the sliding groove 48. The linkage part 51 includes a lifting block 511, which is located in the lifting groove 47. The lifting block 511 slides and cooperates with the lifting groove 47. The second lifting cylinder 52 is fixed to the outer wall of the lifting seat 41, and the piston rod of the second lifting cylinder 52 is fixedly connected to the lifting seat 41. The second lifting cylinder 52 is used to drive the lifting block 511 to move up and down. The first moving part 53 and the second moving part 54 are both located in the sliding groove 48. The first moving part 53 and the second moving part 54 are both slidingly matched with the sliding groove 48. The processing accuracy of the sliding groove 48 is IT7 level, and the matching clearance between the moving part and the sliding groove 48 is controlled between 0.02-0.05mm.

[0044] Reference Figure 4The linkage member 51 also includes a linkage rod 512, which extends along the second direction. The linkage rod 512 passes through the lifting block 511 and is fixedly connected to the lifting block 511. The side wall of the first movable member 53 is provided with a first arcuate groove 531, and the side wall of the second movable member 54 is provided with a second arcuate groove 541. The first arcuate groove 531 and the second arcuate groove 541 intersect with each other. The linkage rod 512 includes a first linkage column 5121 and a second linkage column 5122 that are fixedly connected. The diameter of the first linkage column 5121 is smaller than the diameter of the second linkage column 5122. The first linkage column 5121 is penetrated by the first arcuate groove 531, and the first linkage column 5121 and the first arcuate groove 531 are slidably matched, and the matching clearance is controlled between 0.01-0.03mm. The second linkage column 5122 is penetrated by the second arc groove 541, and the second linkage column 5122 and the second arc groove 541 are slidably matched, and the matching clearance is also controlled between 0.01-0.03mm. The first clamping member 55 is fixed to the lower surface of the first movable member 53, and the second clamping member 56 is fixed to the lower surface of the second movable member 54. The first clamping member 55 and the second clamping member 56 are made of rubber, and the surface of the clamping block in contact with the wire is frosted. The first clamping member 55 is provided with a first locating groove 551 for limiting the wire toward one end of the second clamping member 56, and the second clamping member 56 is provided with a second locating groove 561 for limiting the wire toward one end of the first clamping member 55. The width of the first locating groove 551 and the second locating groove 561 is 0.2-0.3mm larger than the diameter of the wire, and the depth is 1.2-1.5 times the diameter of the wire.

[0045] Reference Figure 1 、 Figure 3 and Figure 4 When clamping the wire, the second lifting cylinder 52 drives the lifting seat 41 to rise and fall, thereby driving the linkage member 51 to move. The lifting block 511 of the linkage member 51 slides within the lifting groove 47, and the linkage rod 512 moves along with the lifting block 511. Because the first linkage column 5121 of the linkage rod 512 is located in the first arcuate groove 531, and the second linkage column 5122 is located in the second arcuate groove 541, and the first arcuate groove 531 and the second arcuate groove 541 intersect with each other, the movement of the linkage rod 512 causes the first moving member 53 and the second moving member 54 to slide along the first direction within the sliding groove 48. The movement of the first moving member 53 and the second moving member 54, in turn, drives the movement of the first clamping member 55 and the second clamping member 56, respectively. When the first clamping member 55 and the second clamping member 56 approach each other, the first positioning groove 551 and the second positioning groove 561 gradually limit the wire, ultimately achieving stable clamping of the wire. This method converts the lifting movement of the lifting seat 41 into horizontal movement of the first movable member 53 and the second movable member 54 through the cooperation of the linkage rod 512 and the arc groove, thereby realizing the clamping of the wire by the clamping block. It has a clever structure and is easy to operate, and can meet the precise clamping requirements of different wires.

[0046] Reference Figure 4 A second guide block 532 is integrally formed at one end of the first moving member 53, and a first guide groove 542 is opened on the side wall of the second moving member 54 facing the first moving member 53. The first guide groove 542 extends along the first direction, and both ends of the first guide groove 542 are open. The second guide block 532 is located in the first guide groove 542, and the second guide block 532 slides and cooperates with the first guide groove 542, thereby increasing the stability of the first moving member 53 and the second moving member 54 moving along the first direction.

[0047] Reference Figure 2 、 Figure 5 and Figure 6 In this embodiment, there are two weaving and cutting mechanisms 6, and the two weaving and cutting mechanisms 6 are arranged at intervals along the first direction. Specifically, each weaving and cutting mechanism 6 includes a sliding rod 61, a first cutting cylinder 62, a second cutting cylinder 63, and a second cylinder 64. A sliding hole 49 is provided at the end of each supporting seat 42, and the sliding hole 49 extends along the second direction. Both ends of the sliding hole 49 are open. The sliding rod 61 is located in the sliding hole 49, and the sliding rod 61 slides with the sliding hole 49. The second cylinder 64 is fixed on the sliding seat 31, and the piston rod of the second cylinder 64 is fixedly connected to the end of the sliding rod 61. A fixed rod 611 is integrally formed at one end of the sliding rod 61 facing the clamping assembly 5, and a penetrating cutting hole 621 is provided at the end of the cutting cylinder. The cutting cylinder is sleeved on the fixed rod 611 and fixedly connected to the fixed rod 611.

[0048] Reference Figure 5 and Figure 6 The second cutting cylinder 63 comprises a first half-cylinder 631 and a second half-cylinder 632. The first half-cylinder 631 is fixed to the side wall of the first clamping member 55 near the support block, and the second half-cylinder 632 is fixed to the side wall of the second clamping member 56 near the support block. When the end of the first clamping member 55 abuts the end of the second clamping member 56, the side wall of the first half-cylinder 631 abuts the side wall of the second half-cylinder 632, and the two combine to form the cylindrical second cutting cylinder 63. A semicircular first through-hole 634 is defined on the side wall of the first half-cylinder 631 near the second half-cylinder 632, and a semicircular second through-hole 635 is defined on the side of the second half-cylinder 632 near the first half-cylinder. Both the first through-hole 634 and the second through-hole 635 extend in the second direction. When the side wall of the first half-cylinder 631 abuts the side wall of the second half-cylinder 632, the first through-hole 634 and the second through-hole 635 combine to form a through-hole through which the wire can pass.

[0049] Reference Figure 5It is worth noting that the diameter of the cutting hole 621 is smaller than the outer diameter of the second cutting cylinder 63, and the diameter of the cutting hole 621 is 0.5mm larger than the diameter of the wire, and the inner diameter of the lead-in hole is 0.5mm larger than the diameter of the wire. The first half cylinder 631 and the second half cylinder 632 are both provided with a cutting chamfer 633 toward one end of the first cutting cylinder 62, and the angle of the cutting chamfer 633 is 30°m. When the first cutting cylinder 62 and the second cutting cylinder 63 cooperate to cut the wire, the coaxiality error between the two does not exceed 0.05mm, and the verticality error does not exceed 0.1mm. When the first cutting cylinder 62 moves toward the direction close to the second cutting cylinder 63, when the end of the first cutting cylinder 62 abuts against the cutting chamfer 633, the first cutting cylinder 62 and the second cutting cylinder 63 jointly complete the circular cutting of the wire.

[0050] Reference Figure 2 、 Figure 5 and Figure 6 When wire cutting is required, the second cylinder 64 begins operation, its piston rod extending and retracting, driving the sliding rod 61 to slide in the second direction within the sliding hole 49. Because the cutting cylinder is sleeved on and fixedly connected to the fixed rod 611, the movement of the sliding rod 61 drives the cutting cylinder along with it. The wire passes through the through-hole formed by the first and second half cylinders 631 and 632, reaching the cutting position. At this point, driven by the second cylinder 64, the first cutting cylinder 62 moves toward the second cutting cylinder 63. When the annular edge of the first cutting cylinder 62 tightly contacts the surface of the cutting chamfer 633, the first and second cutting cylinders 62 and 63 cooperate to apply pressure to the wire, thereby achieving circular cutting. Because the diameter of the cutting hole 621 is smaller than the outer diameter of the second cutting cylinder 63, coupled with the well-designed dimensions of the cutting chamfer 633 and the high-precision fit between the two, the first and second cutting cylinders 62 and 63 cooperate to apply pressure to the wire, thereby achieving circular cutting of the wire.

[0051] Reference Figure 1 Each sliding seat 31 is fixedly provided with a hopper 34 at one end facing the clamping mechanism. The top and bottom ends of the hopper 34 are both open, and the hopper 34 is located directly below the braiding and cutting mechanism 6. Two waste boxes 14 are also fixedly provided on the upper surface of the base plate 11. The waste boxes 14 correspond one to one with the hoppers 34. The waste boxes 14 are located directly below the hoppers 34, and the top ends of the waste boxes 14 are open. When the braiding and cutting mechanism 6 cuts the wire, the cut waste will fall into the top of the hopper 34, and then fall into the waste box 14 located directly below it through the bottom end of the hopper 34, thereby realizing the collection of the cut waste.

[0052] The implementation principle of the above embodiment is as follows: during actual operation, first, according to the model of the wire to be processed, the first cylinder 33 is used to drive the piston rod to extend and retract, driving the sliding seat 31 to move along the first direction, and adjusting the cutting assembly to a suitable position; then, the first lifting cylinder 43 is used to drive the lifting seat 41 to move up and down, and the clamping assembly 5 is adjusted to a suitable height; then, the wire is passed through the through-hole formed by the first half cylinder 631 and the second half cylinder 632; then, the second lifting cylinder 52 is used to drive the lifting seat 41 to move up and down, so that the first clamping member 55 and the second clamping member 56 are close to each other, and under the cooperation of the linkage rod 512 and the arc groove, the first moving member 53 and the second moving member 54 move in the sliding groove 48, thereby driving the first clamping member 55 and the second clamping member 56 to stably clamp the wire; finally, the second cylinder 64 drives the sliding rod 61 to move, pushing the first cutting cylinder 62 to move toward the second cutting cylinder 63, and relying on the cooperation between the cutting hole 621 and the cutting chamfer 633, the wire braiding is cut.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
