Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper strip cutting technology, and in particular to a cutting device for copper strip. Background Technology
[0002] Currently, when a section of copper strip needs to be temporarily cut, it is usually done manually. The dimensions of the cut are subject to human error, and the labor intensity is high. During the manual cutting process, the blade can easily tear the copper strip, causing deformation of the cut end and rendering the copper strip unusable. Furthermore, during cutting, the copper strip on both sides of the cut is prone to curling due to the shearing force.
[0003] Therefore, it is necessary to provide a new cutting device for copper strip to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a cutting device for copper strip.
[0005] The cutting device for copper strip provided by this utility model includes a cutting table, a horizontally arranged cutting groove is provided on the cutting table, and a horizontally placed cutting knife is fixedly installed in the cutting groove. A pressing component for pressing copper strip and a cutting component for cutting copper strip are installed on the cutting table.
[0006] The pressing assembly includes support rods, four of which are symmetrically distributed on shearing tables on both sides of the groove. A top plate is fixedly mounted on the top of each of the four support rods. A sliding plate is slidably connected to each of the four support rods, and a through cavity is opened at the position of the sliding plate corresponding to the groove. A pressing plate is fixedly installed on the lower surface of the sliding plate on both sides of the through cavity. A spring is sleeved on each of the support rods, and a cam is installed on the top plate to drive the sliding plate to slide down along the support rod.
[0007] The cutting assembly includes a central plate, which is disposed between the top plate and the sliding plate and can be raised and lowered. A mounting plate passing through the cavity is fixedly installed at the bottom of the central plate, and a shearing blade is fixedly installed at the bottom of the mounting plate.
[0008] Preferably, a mounting frame is fixedly suspended on the lower surface of the top plate, the cam is rotatably mounted on the mounting frame via a rotating shaft, and a knob is fixedly mounted on the rotating shaft of the cam, with the wheel surface of the cam abutting against the top plate and the sliding plate respectively.
[0009] Preferably, one end of the spring is fixedly connected to the shearing table, and the other end of the spring is fixedly connected to the lower surface of the sliding plate.
[0010] Preferably, a rubber pad is fixedly fitted to the bottom of the pressing plate.
[0011] Preferably, the cutting assembly further includes a threaded rod and a limiting rod, which are distributed on both sides of the shearing table. The two ends of the threaded rod are rotatably connected to the shearing table and the top plate, respectively. A servo motor for driving the threaded rod to rotate is installed on the shearing table. The two ends of the limiting rod are fixedly connected to the shearing table and the top plate, respectively. A threaded cylinder and a sliding cylinder are fixedly installed on both ends of the connecting plate, respectively. The threaded cylinder is sleeved on the threaded rod and threadedly connected to the threaded rod, and the sliding cylinder is sleeved on the limiting rod and slidably connected to the limiting rod.
[0012] Preferably, brackets are fixedly installed on both sides of the lower surface of the shearing table.
[0013] Compared with related technologies, the shearing device for copper strips provided by this utility model has the following advantages:
[0014] This invention uses a rotating knob to rotate the cam's protruding part towards the sliding plate. Consequently, the cam's protruding part pushes the sliding plate down the support rod and presses the spring. Once the cam's protruding part is vertically downward, the pressing plate firmly presses the copper strip on both sides of the copper strip shearing point, thereby fixing the copper strip. This avoids the potential for displacement during copper strip shearing, which could lead to excessively long or short shearing lengths. It also reduces the risk of bending at the copper strip shearing point. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0021] Please see Figures 1 to 3 This utility model provides a cutting device for copper strip, which includes a cutting table 1, a pressing assembly 2, and a cutting assembly 3.
[0022] In the embodiments of this utility model, please refer to Figures 1 to 3 The shearing table 1 is equipped with a pressing assembly 2 for pressing copper strips. The pressing assembly 2 includes support rods 21. Four support rods 21 are symmetrically distributed on both sides of the shearing table 1 of the groove 1a. A top plate 22 is fixedly mounted on the top of each of the four support rods 21. Sliding plates 23 are mounted on the four support rods 21. A cavity 23a is opened on the sliding plate 23 at the position corresponding to the groove 1a. A pressing plate 27 is fixedly mounted on the lower surface of the sliding plate 23 on both sides of the cavity 23a. A rubber pad is fixedly embedded at the bottom of the pressing plate 27. A spring 24 is fitted onto the support rod 21, one end of which is fixedly connected to the shearing table 1, and the other end of which is fixedly connected to the lower surface of the sliding plate 23. A cam 25 is installed on the top plate 22 to drive the sliding plate 23 to slide down the support rod 21. Specifically, a mounting bracket 251 is fixedly suspended on the lower surface of the top plate 22, and the cam 25 is rotatably mounted on the mounting bracket 251 via a rotating shaft. A knob 26 is fixedly installed on the rotation axis of the cam 25, and the wheel surface of the cam 25 abuts against the top plate 22 and the sliding plate 23 respectively.
[0023] It should be noted that when temporarily cutting the copper strip, the copper strip is unfolded and laid on the shearing table 1. Subsequently, the copper strip is stretched along the shearing table 1 and passed through the cutting groove 1a, so that the copper strip passing through the cutting groove 1a meets the required length. After completion, the knob 26 is rotated so that the protruding part of the cam 25 rotates towards the sliding plate 23. Therefore, the protruding part of the cam 25 pushes the sliding plate 23 down along the support rod 21 and presses the spring 24. After the protruding part of the cam 25 is vertically downward, the pressing plate 27 firmly presses the copper strip on both sides of the copper strip at the cut point, thereby fixing the copper strip. On the one hand, this avoids the hidden danger of displacement during copper strip cutting, which may cause the cut length to be too long or too short. On the other hand, it reduces the hidden danger of the strip surface bending at the cut point.
[0024] In this embodiment: when the protruding part of the cam 25 is vertically downward, the spring 24 is compressed, so that the sliding plate 23 and the contact surface of the protruding part of the cam 25 are firmly abutted, making it difficult for the cam to slip sideways.
[0025] Furthermore, brackets 11 are fixedly installed on both sides of the lower surface of the shearing table 1, which improves the stability of the shearing table 1.
[0026] In the embodiments of this utility model, please refer to Figures 1 to 3 The shearing table 1 has a horizontally arranged cutting groove 1a. A cutting assembly 3 for shearing copper strips is installed on the shearing table 1. The cutting assembly 3 includes a connecting plate 31, which is positioned between a top plate 22 and a sliding plate 23 and can be raised and lowered. A mounting plate 34 passing through a through cavity 23a is fixedly installed at the bottom of the connecting plate 31. A shearing blade 35 is fixedly installed at the bottom of the mounting plate 34. The cutting assembly 3 also includes a threaded rod 36 and a limiting rod 37, which are distributed in... On both sides of the shearing table 1, the two ends of the threaded rod 36 are rotatably connected to the shearing table 1 and the top plate 22, respectively. A servo motor 361 for driving the threaded rod 36 to rotate is installed on the shearing table 1. The two ends of the limiting rod 37 are fixedly connected to the shearing table 1 and the top plate 22, respectively. A threaded cylinder 32 and a sliding cylinder 33 are fixedly installed on both ends of the connecting plate 31, respectively. The threaded cylinder 32 is sleeved on the threaded rod 36 and threadedly connected to the threaded rod 36, and the sliding cylinder 33 is sleeved on the limiting rod 37 and slidably connected to the limiting rod 37.
[0027] It should be noted that: when the servo motor 361 is turned on to drive the threaded rod 36 to rotate, the sliding cylinder 33 on the connecting plate 31 is limited by the limit rod 37, so the shearing blade 35 on the bottom mounting plate 34 of the connecting plate 31 can descend and cut the copper strip.
[0028] Furthermore, to facilitate the cutting of copper strip by the shearing blade 35, a horizontally positioned bottom cutter can be fixedly installed in the cutting groove 1a, thereby facilitating the shearing blade 35 to work with the bottom cutter to cut the copper strip.
[0029] The working principle of the copper strip shearing device provided by this utility model is as follows:
[0030] When temporarily cutting the copper strip, the copper strip is unfolded and laid on the shearing table 1. Subsequently, the copper strip is stretched along the shearing table 1 and passed through the cutting groove 1a, so that the copper strip passing through the cutting groove 1a meets the required length. After completion, the knob 26 is rotated so that the protruding part of the cam 25 rotates towards the sliding plate 23. Therefore, the protruding part of the cam 25 pushes the sliding plate 23 down along the support rod 21 and presses the spring 24. After the protruding part of the cam 25 is vertically downward, the pressing plate 27 firmly presses the copper strip on both sides of the copper strip at the cutting point, thereby fixing the copper strip. On the one hand, it avoids the hidden danger of displacement during copper strip cutting, which may cause the cutting length to be too long or too short. On the other hand, it reduces the hidden danger of the strip surface bending at the cutting point. The servo motor 361 is turned on to drive the threaded rod 36 to rotate. Since the sliding cylinder 33 on the connecting plate 31 is limited by the limit rod 37, the shearing blade 35 on the mounting plate 34 at the bottom of the connecting plate 31 can descend and cut the copper strip.
[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
