Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper wire cutting technology, specifically a fixed-length cutting machine. Background Technology
[0002] Copper wire is often used as a conductor in lamps due to its high electrical conductivity and good heat dissipation performance. High electrical conductivity means that the resistance encountered when the current flows in the copper wire is small, which can reduce energy loss. At the same time, the heat dissipation performance of copper wire helps to maintain the stable operation and life of the lamp. Since the structure of lamps is diverse, different lamps require copper wires of different lengths in the design and manufacturing process.
[0003] Traditional copper wire cutting methods rely heavily on manual operation. The manual cutting process requires manual measurement and cutting, and the copper wire must be manually collected after cutting. The cutting process is relatively complicated, which is not only inefficient, but also makes it difficult to ensure the consistency of the cut length, which can easily lead to production defects and increase production costs.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] Please see Figure 1-8 In this embodiment of the present invention, a fixed-length cutting machine includes an operating table 100. Guide wheels 110 and 120 are symmetrically rotatably connected to the top surface of the operating table 100. A cutting mechanism 200 is provided on the top surface of the operating table 100. The cutting mechanism 200 includes a portal frame 210. The bottom end of the portal frame 210 is fixedly connected to the top surface of the operating table 100. An electric telescopic rod 220 is fixedly connected to the inner top surface of the portal frame 210. A blade holder 230 is fixedly connected to the output end of the electric telescopic rod 220. A cutting blade 240 is fixedly connected to the bottom surface of the blade holder 230. A collection box is fixedly connected to the end side of the operating table 100. 300. The end of the collection box 300 away from the operating table 100 is not sealed. A positioning mechanism 400 is provided above the collection box 300. The positioning mechanism 400 includes an upper limit block 410. A baffle 420 is fixedly connected to the side of the upper limit block 410 away from the operating table 100. Two lower limit blocks 430 are symmetrically arranged below the upper limit block 410. A connecting rod 440 is fixedly connected to the two opposite side walls of the upper limit block 410. An electric telescopic rod 450 is fixedly connected to the inner side wall of the two connecting rods 440. The output ends of the two electric telescopic rods 450 are fixedly connected to the side walls of the two lower limit blocks 430 respectively.
[0032] Specifically, the copper wire is moved between guide wheel 110 and guide wheel 120 to the cutting mechanism 200. The cutting mechanism 200 is located on the top surface of the operating table 100 near the edge. The distance between the positioning mechanism 400 and the cutting mechanism 200 is adjusted according to the required cutting size. The bottom surface of the baffle 420 is provided with an arc-shaped groove, and the opposite sides of the two lower limit blocks 430 are also provided with arc-shaped grooves. The arc-shaped grooves between the three form a circular opening. The baffle 420 on the side wall of the upper limit block 410 blocks the side of this circular opening away from the cutting mechanism 200. At this time, the rear end of the copper wire is fed forward and enters the upper limit block 410 and the two lower limit blocks 430. The copper wire is cut into the circular slot formed between the position blocks 430 and blocked by the baffle 420 to prevent it from moving forward. The electric telescopic rod 220 is extended, which drives the blade holder 230 to move down, so that the cutting blade 240 cuts the copper wire. After the cutting is completed, the two electric telescopic rods 450 drive the two lower limit blocks 430 to retract, so that the two lower limit blocks 430 move away from each other, so that a gap appears at the bottom of the circular slot formed by the upper limit block 410 and the two lower limit blocks 430, so that the cut copper wire falls naturally into the collection box 300 below and is collected. The side of the collection box 300 away from the operating table 100 is not blocked and is open, making it easy to take out the cut copper wire.
[0033] like Figure 8 As shown, in this embodiment, the operating table 100 has an internal cavity. The bottom surfaces of the guide wheel 110 and the guide wheel 2120 are respectively fixedly connected to the rotating shaft 111 and the rotating shaft 2121. The bottom ends of the rotating shaft 111 and the rotating shaft 2121 extend into the cavity of the operating table 100. The bottom end of the rotating shaft 111 is rotatably connected to the inner wall of the operating table 100. The outer walls of the rotating shaft 111 and the rotating shaft 2121 are respectively fitted and fixed with gear 112 and gear 2122. The gear 112 and the gear 2122 mesh and drive each other. A servo motor 130 is fixedly connected inside the cavity of the operating table 100. The motor shaft of the servo motor 130 is drivenly connected to the bottom end of the rotating shaft 2121.
[0034] In this embodiment, the copper wire is threaded between guide wheel 110 and guide wheel 120, and the servo motor 130 is started. The motor shaft of the servo motor 130 is driven by the rotating shaft 121, which drives the gear 122 to rotate. The gear 122 meshes with the gear 112, causing the guide wheel 110 and guide wheel 120 to rotate in opposite directions. Thus, the guide wheel 110 and guide wheel 120 can transport the copper wire toward the cutting mechanism 200.
[0035] like Figure 6As shown, in this embodiment, the top surface of the collection box 300 has two rectangular grooves 310, the bottom ends of the two connecting rods 440 are slidably connected to the two rectangular grooves 310 respectively, and the two outer side walls of the collection box 300 are provided with sliding grooves 320 at positions corresponding to the rectangular grooves 310. The outer side walls of the two connecting rods 440 are fixedly connected with studs 441, the outer walls of the two studs 441 are in contact with the inner walls of the two sliding grooves 320 respectively, and the outer walls of the two studs 441 are screwed with nuts 442.
[0036] In practice, the bottom end of the connecting rod 440 is slidably connected to the inside of the rectangular groove 310, so that the connecting rod 440 can be moved along the rectangular groove 310 according to the diverse requirements of different lamps for the length of copper wire, so as to change the distance between the positioning mechanism 400 and the cutting mechanism 200. After moving to the required position, the position of the positioning mechanism 400 is fixed by tightening the nut 442 to prevent the position of the positioning mechanism 400 from changing during the cutting process.
[0037] like Figure 4-5 As shown, in this embodiment, the bottom surface of the upper limit block 410 has two sliding grooves 411, and the top surfaces of the two lower limit blocks 430 are fixedly connected with sliders 431, and the two sliders 431 are slidably connected to the two sliding grooves 411 respectively.
[0038] In practice, when the electric telescopic rod 450 extends or retracts, the lower limit block 430 will move accordingly, and the slider 431 will move along the inside of the slide groove 411, thereby enhancing the stability of the movement of the lower limit block 430.
[0039] Example 2
[0040] Based on Example 1, in order to keep the copper wire relatively stable when it is cut.
[0041] like Figure 2 and Figure 7 As shown, in this embodiment, a receiving seat 140 is fixedly connected to the top surface of the operating table 100 directly below the cutting mechanism 200. A cutting groove 141 is opened on the top surface of the receiving seat 140, and a feed hole 142 is opened through the side wall of the receiving seat 140. Two circular holes are symmetrically opened on the top surface of the knife holder 230. A circular rod 250 is slidably inserted into each of the two circular holes. A limit plate 251 is fixedly connected to the top of each of the two circular rods 250. The bottom ends of each of the two circular rods 250 are fixedly connected to the top surface of the operating table 100. A return spring 260 is sleeved on the outer wall of each of the two circular rods 250. One end of the return spring 260 is fixedly connected to the bottom surface of the knife holder 230, and the other end of the return spring 260 is fixedly connected to the top surface of the operating table 100.
[0042] In practice, the receiving seat 140 is located directly below the cutting mechanism 200, and the size of the cutting groove 141 matches the size of the cutting blade 240. Two round rods 250 are located on both sides of the receiving seat 140. When in use, the copper wire is passed between the guide wheel 110 and the guide wheel 120, and then through the feed hole 142 to the positioning mechanism 400. At this time, the electric telescopic rod 220 is extended to drive the blade holder 230 to move down. The return spring 260 is compressed by the blade holder 230. The cutting blade 240 moves down with the blade holder 230 and cuts the part of the copper wire inside the feed hole 142 along the cutting groove 141. After the cutting is completed, the electric telescopic rod 220 retracts, driving the cutting blade 240 to move up until the return spring 260 returns to its original state. The receiving seat 140 restricts the position of the copper wire, while the round rods 250 and the return spring 260 ensure the stability of the position of the cutting blade 240, preventing it from shifting during cutting and avoiding affecting the cutting accuracy.
[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
