[0001] This utility model belongs to the technical field of copper rod processing equipment, and in particular relates to a copper rod cutting machine. Background Technology

[0002] A copper rod cutting machine is a mechanical device specifically designed for processing copper rod materials, widely used in metal processing, manufacturing, and related industries. Its main function is to cut long copper rods into smaller segments of a specified length to meet the needs of subsequent processing or production. For example, a copper rod cutting machine for the copper industry disclosed in patent application number CN201720633670.6 includes a fixed platform, the bottom of which is fixedly connected to the top of a fixed base, the bottom of which is fixedly connected to the top of a base, symmetrical support frames arranged on the left and right sides of the top of the fixed platform, the top of which is fixedly connected to the bottom of a horizontal plate, the top of which is fixedly connected to the bottom of a cylinder seat, and a hydraulic cylinder mounted on the top of the cylinder seat.

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.

[0043] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0044] Example 1:

[0045] This application provides a copper rod cutting machine, including: a machine body 1, a machine cavity 2 is provided inside the machine body 1, and a frame 3 is provided on the machine body 1; a cutting mechanism 7 is provided on the frame 3, and the cutting mechanism 7 includes a blade cover 70, a blade body 71 and a drive unit 72.

[0046] It also includes: a clamping mechanism, which includes two clamping parts 4 and a driving part 5 for moving the two clamping parts 4; and a sharpening part 6, which is disposed on both sides of the blade cover 70 and includes a sharpening stone 60 for sharpening the blade body 71.

[0047] The clamping part 4 can clamp the copper rod, and the two clamping parts 4 can move away from or towards each other along the length of the body 1.

[0048] Furthermore, the drive unit 72 can be composed of a conventional lifting drive structure and a blade body 71 drive structure, such as a lifting drive cylinder 41 and a rotary motor. The lifting drive cylinder 41 is mounted on the frame 3, and the drive end of the lifting drive cylinder 41 is connected to the blade cover 70 to drive the blade cover 70 to move up and down. The blade body 71 is mounted in the blade cover 70 through a conventional rotating connection, and the lower half of the blade body 71 is located outside the blade cover 70. The rotary motor is mounted on the blade cover 70 and connected to the blade body 71 to drive the blade body 71 to rotate. A conventional control unit, such as a PLC control unit, is also installed on the machine body 1.

[0049] In this technical solution, during the use of the copper rod cutting machine, the copper rod is clamped by two clamping parts 4 of the clamping mechanism. When dealing with cutting operations of copper rods of different lengths, the drive unit 5 can drive the two clamping parts 4 to move away from or closer to each other along the length direction of the machine body 1, thereby adapting to the clamping of copper rods of different lengths and improving the adaptability of the copper rod cutting machine. After the copper rod is clamped, the copper rod is cut by the blade 71 on the cutting mechanism 7. During use, the blade 71 can be sharpened by the whetstone 60 on the whetstone part 6, thereby maintaining the sharpness of the blade 71, reducing the replacement frequency of the blade 71, and thus effectively improving work efficiency.

[0050] Example 2:

[0051] This embodiment provides a copper rod cutting machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the drive unit 5 further includes: a central gear 50, which is rotatably disposed in the equipment cavity 2 and is driven to rotate by a gear motor; a rack 51, which is movably disposed in the equipment cavity 2, and has two racks located on both sides of the central gear 50, with the two racks 51 being staggered, and a connecting arm 53 is provided on the rack 51; a moving groove 52, which is disposed on the surface of the machine body 1 and communicates with the equipment cavity 2, and a moving mounting seat 54 is movably disposed on the moving groove 52, and has two moving mounting seats 54 which are symmetrically distributed along the length direction of the machine body 1;

[0052] The clamping part 4 is disposed on the movable mounting base 54, the upper end of the connecting arm 53 is connected to the bottom of the movable mounting base 54, and the rack 51 meshes with the central gear 50.

[0053] Furthermore, the gear motor can be installed in the equipment cavity 2 or installed outside the machine body 1 with the drive end extending into the equipment cavity 2. The moving direction of the rack 51 is parallel to the length direction of the machine body 1, and the moving directions of the two racks 51 are always opposite. The moving groove 52 is a strip groove and is distributed along the length direction of the machine body 1. The moving mounting base 54 is movably installed on the moving groove 52 in a conventional manner, such as by means of a slide rail or slide groove.

[0054] In this embodiment, when adjusting the clamping part 4 of the clamping mechanism, the central gear 50 is driven to rotate. The rotation of the central gear 50 drives the two racks 51 meshing with it to move. The two racks 51 move in opposite directions. As the racks 51 move, the two movable mounting seats 54 move away from or closer to each other along the movable groove 52 under the drive of the connecting arm 53. This adjusts the distance between the two movable mounting seats 54, so that the distance between the clamping parts 4 on the two movable mounting seats 54 changes, adapting to the clamping of copper rods of different lengths and improving the adaptability of the copper rod cutting machine.

[0055] Example 3:

[0056] This embodiment provides a copper rod cutting machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the grinding part 6 further includes: a housing 61, which is disposed on the side wall of the blade cover 70; a movable rod 62, which is movably inserted through the housing 61 and the blade cover 70, with the axial direction of the movable rod 62 parallel to the axial direction of the blade 71, one end of the movable rod 62 located inside the blade cover 70, and the other end located inside the housing 61; a magnetic chuck 63, which is disposed at the end of the movable rod 62 located inside the housing 61; an electromagnet 64, which is disposed on the inner side wall of the housing 61 and located on the side of the magnetic chuck 63 near the blade 71; and an elastic reset member 65, which is disposed on the inner side wall of the housing 61 and located to the side of the electromagnet 64, with the end of the elastic reset member 65 connected to the magnetic chuck 63.

[0057] The whetstone 60 is located at one end of the movable rod 62 inside the blade cover 70.

[0058] Furthermore, the elastic reset member 65 can be a conventional elastic telescopic rod. Several electromagnets 64 and elastic reset members 65 can be installed and evenly distributed around the movable rod 62. Holes for the movable rod 62 to move are provided on the outer shell 61 and the blade cover 70. The movable rod 62 moves through the outer shell 61 and the blade cover 70 through the holes. Conventional reinforcing structures such as annular reinforcing protrusions can be installed at both ends of the holes.

[0059] In this embodiment, during the use of the copper rod cutting machine, after the blade 71 completes the cutting action on the copper rod, the rotation speed of the blade 71 decreases. At this time, the electromagnet 64 is activated. After the electromagnet 64 is activated, it generates magnetism and attracts the magnetic chuck 63. Under the attraction of the magnetism, the magnetic chuck 63 moves towards the electromagnet 64. At the same time, the movable rod 62 moves with the magnetic chuck 63, eventually causing the whetstone 60 to contact the blade 71. After the magnetic chuck 63 is attracted to the electromagnet 64, the elastic reset member 65 is simultaneously compressed. After the whetstone 60 contacts the blade 71, it grinds the blade 71 as the blade 71 rotates, maintaining the sharpness of the blade 71. After grinding is completed, the operation of the electromagnet 64 is stopped, and the elastic reset member 65 resets the magnetic chuck 63 through elastic force, thereby driving the movable rod 62 to reset, and finally separating the whetstone 60 from the blade 71. Compared with the prior art, this utility model can effectively maintain the sharpness of the blade 71, reduce the replacement frequency of the blade 71, and thus effectively improve work efficiency.

[0060] Example 4:

[0061] This embodiment provides a copper rod cutting machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the clamping part 4 further includes: a mounting ring 40, which is disposed on a movable mounting base 54. Two drive cylinders 41 are disposed on the mounting ring 40, and the two drive rods are symmetrically distributed radially along the mounting ring 40; a clamping ring 42, which is disposed inside the mounting ring 40 and concentrically distributed with the mounting ring 40. The clamping ring 42 is composed of several ring segments 420, and adjacent ring segments 420 are connected to each other by an arc-shaped telescopic rod 43.

[0062] The drive end of the drive cylinder 41 is connected to the ring segment 420.

[0063] The clamping ring 42 has two segments 420 that are spaced apart along the axial direction of the mounting ring 40, and the segments 420 on the two clamping rings 42 are staggered with each other.

[0064] In this embodiment, when the clamping part 4 clamps the copper rod, the drive cylinder 41 operates to drive the ring segment 420 connected to it to move, so that the ring segment 420 approaches the surface of the copper rod and is finally pressed against the surface of the copper rod. After the copper rod is clamped, the ring segment 420 can form multiple clamping surfaces on the surface of the copper rod, which effectively improves the clamping stability of the copper rod. At the same time, through the setting of two clamping rings 42, the ring segments 420 on the two clamping rings 42 are staggered and distributed with each other, which can further supplement the number of effective clamping surfaces, thereby further improving the clamping stability of the clamping part 4 on the copper rod.

[0065] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
