Description

Technical Field

[0001] This utility model relates to the field of cutting machinery technology, and in particular to a rapid cutting and unloading device for silver alloy oxide wire reels. Background Technology

[0002] The preparation of silver alloy oxide wire is one of the important steps in the production of electrical contact materials. During the production of alloy wire, the wire becomes brittle and easily breaks after oxidation. In order to improve the ductility of the wire, the oxide wire needs to be cut, pressed into ingots, heated and extruded, and then drawn into oxide wire that meets the requirements.

[0003] Existing anodized wire cutting devices involve manually cutting the wire wound into a coil. Because the wire is wound into a coil, such as... Figure 1 As shown, the coiled wire needs to be cut and straightened first, and then manually cut using conventional cutting equipment. This cutting operation is time-consuming, and because the wire needs to be cut into lengths of several centimeters, personnel need to operate the cutting frequently and continuously, resulting in high labor intensity and the possibility that the cut wires may be of varying lengths. Summary of the Invention

[0004] To address the problem of cumbersome manual cutting operations for oxidized wire coils, this invention provides a rapid cutting and unloading device for silver alloy oxidized wire coils. By using a hydraulic press in conjunction with a mold, a single coil can be directly cut in one operation, improving cutting efficiency and ensuring that the length of the cut wire is basically consistent.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapid cutting and unloading device for silver alloy oxide wire coils includes a hydraulic press, a mold assembly, and an unloading device. The hydraulic press has a movable platform on the piston rod of the hydraulic cylinder, which facilitates the up-and-down movement of the movable platform. The movable platform and the hydraulic press worktable are arranged at intervals.

[0007] The mold assembly includes an upper punch and a lower die. The upper punch is located below the movable table and moves up and down with the movable table. The lower die is located on the worktable and passes through the worktable. When the upper punch moves down and cooperates with the lower die, it directly cuts the coiled wire into multiple small segments in one go.

[0008] The unloading device includes an unloading frame mounted on a hydraulic press, multiple connecting rods arranged circumferentially below the unloading frame, and an unloading plate. The unloading frame surrounds the hydraulic cylinder of the hydraulic press and does not interfere with the operation of the hydraulic cylinder. Each connecting rod extends vertically downward through the movable table to the upper punch and is connected to the unloading plate. The unloading plate slides in the upper punch to facilitate the separation of the wire inside the upper punch.

[0009] Furthermore, the hydraulic press includes a frame, a hydraulic cylinder, and a worktable. The hydraulic cylinder is mounted on the top of the frame and is a master-slave hydraulic cylinder. The worktable is also mounted on the frame, and there is a gap between the hydraulic cylinder and the worktable.

[0010] Furthermore, multiple sets of guide components are provided between the worktable and the movable table, each set including a guide rod and a linear bearing; a guide rod is provided above the worktable, the guide rod is arranged vertically, a linear bearing is provided on the movable table, the linear bearing passes through the movable table, and the guide rod passes upward through the linear bearing and is slidably connected to the linear bearing. The guide components improve the stability of the movable table's vertical movement.

[0011] Furthermore, the upper punch includes an upper die base and a plurality of punches detachably disposed on the upper die base. The plurality of punches are circumferentially disposed below the upper die base, and there is a gap between adjacent punches, with the stripper plate sliding within the gap.

[0012] Furthermore, the lower die includes a lower die bottom, an inner die ring, and an outer die ring. The lower die bottom is provided with multiple die holes in a circumferential direction. The shape of the die holes is consistent with the shape of the punch cutter. The die holes and the punch cutter correspond one-to-one. The punch cutter is inserted downward into the die hole to cut the wire.

[0013] The inner mold ring is detachably disposed at the center above the bottom of the lower mold, and the outer mold ring is detachably disposed on the periphery. Grooves are respectively opened on the outer wall of the inner mold ring and the inner wall of the outer mold ring to allow space for the mold hole and avoid interference with the mold hole. The inner mold ring and the outer mold ring are spaced apart to form an annular wire feeding groove, which facilitates the placement of coiled wire.

[0014] Furthermore, the unloading rack includes a lifting rod and a lifting plate. The lifting plate is connected and fixed to the hydraulic press through the lifting rod. The lifting plate is an annular plate. The connecting rod is provided below the lifting plate. The connecting rod is slidably connected to the movable table and the upper punch. The connecting rod extends downward into the space between two adjacent punches. The unloading plate is slidably connected between two adjacent punches.

[0015] The beneficial effects of this utility model through the above technical solution are:

[0016] This invention uses a hydraulic press as the driving force and a specially designed mold assembly. With the cooperation of the upper punch and lower die, it can cut the coiled wire into multiple uniform small segments in one go, realizing the rapid cutting of single-pass batches of wire. Moreover, it accurately determines the cutting length of the wire and the cut surface of the end is flat, effectively solving the problems of cutting efficiency and uniformity of cutting length of alloy wire coils.

[0023] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0024] like Figures 2-5 As shown, a rapid cutting and unloading device for silver alloy oxide wire spools includes a hydraulic press, a mold assembly, and an unloading device. The hydraulic press provides the driving force required for cutting and includes a frame 1, a hydraulic cylinder 2, and a worktable 3. The hydraulic cylinder 2 is mounted on the top of the frame 1, and the worktable 3 is also mounted on the frame 1. The hydraulic cylinder 2 and the worktable 3 are spaced apart vertically.

[0025] The driving force of hydraulic cylinder 2 is provided by a hydraulic pump station, which provides the required pressure and flow rate for hydraulic cylinder 2. Hydraulic cylinder 2 adopts a master-slave cylinder design, which is existing technology, consisting of a large cylinder with a small cylinder embedded inside. The small cylinder can descend rapidly, and when it approaches the workpiece, it can switch to the large cylinder to slowly pressurize and descend according to the corresponding settings, thereby achieving the cutting of the wire load.

[0026] The large and small hydraulic cylinders are each equipped with independent valve groups for operation control, allowing for separate control of their start / stop and stroke adjustment. A PLC controller and three limit switches are mounted on frame 1, spaced at the top, middle, and bottom. A sensing component, such as a movable platform 4, is installed on the small hydraulic cylinder. Initially, the component contacts the first limit switch, resetting hydraulic cylinder 2. Upon starting hydraulic cylinder 2, the controller extends the small cylinder via the corresponding valve group. The small cylinder moves the component downwards until it contacts the second limit switch. At this point, the controller extends the large hydraulic cylinder via the corresponding valve group, moving the small cylinder and component downwards together. When the component contacts the third limit switch, hydraulic cylinder 2 reaches its final position and stops operating.

[0027] A movable platform 4 is mounted on the piston rod of the hydraulic cylinder 2 of the hydraulic press, enabling the hydraulic cylinder 2 to drive the movable platform 4 to move up and down. The movable platform 4 and the worktable 3 of the hydraulic press are arranged vertically at intervals and remain parallel. To improve the stability of the movement of the movable platform 4, multiple sets of guide members 5 are provided between the worktable 3 and the movable platform 4, which ensure the stability of the vertical movement of the movable platform 4.

[0028] Each set of guide components 5 includes a guide rod 51 and a linear bearing 52. During installation, the guide rod 51 is positioned above the worktable 3, and is arranged vertically. The linear bearing 52 is positioned on the movable table 4, passing through it. The guide rod 51 passes upward through the linear bearing 52 and is slidably connected to it. During the up-and-down movement of the movable table 4, it is always guided by the guide rod 51, ensuring the accuracy of the lifting position.

[0029] The die assembly includes an upper punch 6 and a lower die 7. The upper punch 6 moves downward to cooperate with the lower die 7 to directly cut the coiled wire into multiple small segments in one go. The upper punch 6 is located below the movable table 4, so the upper punch 6 can move up and down with the movable table 4. The upper punch 6 includes an upper die base 61 and multiple punch cutters 62 detachably mounted on the upper die base 61. The upper die base 61 is bolted to the movable table 4. The multiple punch cutters 62 are arranged circumferentially below the upper die base 61 and bolted to the upper die base 61. There is a gap between adjacent punch cutters 62. The punch cutters 62 are fan-shaped annular cylinders made of Cr12MoV.

[0030] The lower die 7 is set on the worktable 3 and passes through the worktable 3. The position of the lower die 7 is fixed. The lower die 7 includes a lower die bottom 71, an inner die ring 72 and an outer die ring 73. The lower die bottom 71 is provided with multiple die holes 8 in a circumferential direction. The die holes 8 correspond one-to-one with the punch cutter 62. The shape of the die hole 8 is consistent with the shape of the punch cutter 62. The punch cutter 62 is inserted downward into the die hole 8 to cut the wire.

[0031] An inner mold ring 72 is bolted to the center of the lower mold base 71, and an outer mold ring 73 is bolted to the periphery of the lower mold base 71. Grooves are formed on the outer wall of the inner mold ring 72 and the inner wall of the outer mold ring 73, resulting in continuous, uneven annular surfaces. These grooves are designed to accommodate the mold hole 8, preventing obstruction and ensuring proper fit between the punch cutter 62 and the mold hole 8. An annular wire feeding groove 9, 50-100mm wide, is formed between the inner mold ring 72 and the outer mold ring 73, where coiled wire is placed for cutting.

[0032] The unloading device includes an unloading frame 10 mounted on the hydraulic press, multiple connecting rods 11 arranged circumferentially below the unloading frame 10, and an unloading plate 12. The entire unloading device is fixed in position. The unloading frame 10 surrounds the hydraulic cylinder 2 of the hydraulic press. The unloading frame 10 includes a lifting rod 101 and a lifting plate 102. The lifting plate 102 is connected and fixed to the frame 1 of the hydraulic press through the lifting rod 101. The lifting plate 102 is an annular plate and is fitted around the outside of the hydraulic cylinder 2 without affecting the normal operation of the hydraulic cylinder 2.

[0033] A cylindrical connecting rod 11 is provided below the hanging plate 102. Each connecting rod 11 extends vertically downward through the movable table 4 and into the upper punch 6. Specifically, the connecting rod 11 extends downward between two adjacent punches 62, thereby restricting the position of the connecting rod 11. The connecting rod 11 is slidably connected to the movable table 4 and the upper punch 6.

[0034] A connecting rod 11 extends into the upper punch 6 and is connected to a stripper plate 12. Both ends of the connecting rod 11 are threaded, and the connecting rod 11 is threadedly connected to the hanging plate 102 and the stripper plate 12 respectively, enabling a detachable installation method. The stripper plate 12 is a fan-shaped ring, and its width is consistent with the distance between two adjacent punches 62. The stripper plate 12 slides between two adjacent punches 62. The purpose of the stripper plate 12 sliding within the upper punch 6 is to separate the wire inside the upper punch 6.

[0035] The principle of this invention is as follows: The coiled wire is placed into the wire feeding groove 9, and the coiled wire fits perfectly into the annular wire feeding groove 9. Then, the hydraulic cylinder 2 is activated, and the piston rod drives the movable table 4 and the upper punch 6 to move downward together. The punch cutter 62 moves down and first enters the groove between the outer wall of the inner die ring 72 and the inner wall of the outer die ring 73, and then enters the die hole 8, thereby uniformly cutting the wire in the wire feeding groove 9 into multiple small segments.

[0036] Since the lower die 7 penetrates the worktable 3, a portion of the cut wire falls through the die hole 8 to the bottom of the frame 1. A material basket 13 can be placed below the frame 1 to collect the cut wire. Another portion of the cut wire may get stuck between two adjacent punches 62. Therefore, after the hydraulic cylinder 2 drives the upper punch 6 upward, the stripper plate 12 moves downward relative to the upper punch 6, and then pushes out the stuck wire through the stripper plate 12, realizing the rapid separation of the wire from the upper punch 6, so that the wire falls into the lower die 7.

[0037] Under safe conditions, personnel can use an air gun or brush to remove the wire from the lower die 7, causing it to fall into the material basket 13. After cleaning, the coiled wire can be taken out again, placed into the wire release trough 9, and the cutting operation can begin again.

[0038] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
