Description

Technical Field

[0001] This invention relates to the field of nickel-chromium production technology, and in particular to a cutting machine tool for producing and processing nickel-chromium wire. Background Technology

[0002] Nickel and chromium are two metallic elements. They can be alloyed with impurities such as iron, aluminum, silicon, carbon, and sulfur to form nickel-chromium wire. Nickel-chromium wire has high resistivity and heat resistance. It is used as a heating element in electric furnaces, soldering irons, and electric irons. In the production process of nickel-chromium wire, when large pieces of raw material need to be broken into smaller, easier-to-process pieces, a vertical breaking machine is usually used. This type of breaking machine generally uses heavy-duty cutting tools and is highly efficient.

[0003] Most existing crushing machines directly crush raw materials from above. Such devices do not restrict the position of the raw materials during the crushing process, causing the position of the raw material strip to deflect during the crushing process, resulting in a change in the crushing point and thus reducing the crushing efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, which often directly cut raw materials from above. Such devices do not restrict the position of the raw materials during the cutting process, causing the position of the raw material strip to deflect during the cutting process, resulting in a change in the cutting point and thus reducing the cutting efficiency. Therefore, this invention proposes a cutting machine tool for nickel-chromium wire production and processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cutting machine tool for producing and processing nickel-chromium wire, comprising: A pressure breaking assembly, comprising a processing table and an upper pressure knife, wherein the processing table has an installation groove in the middle and a transmission groove on one side, the installation groove and the transmission groove are arranged perpendicularly to each other and form a T shape, and two transmission assemblies are symmetrically arranged inside the installation groove, and the upper pressure knife is arranged directly above the installation groove; The linkage assembly includes a mounting rod, a rotating sleeve, a first piston rod, a second piston rod, and mounting blocks. The two mounting blocks are L-shaped and symmetrically fixedly connected to both sides of the pressure-breaking assembly. Each mounting block has an L-shaped cavity. The first piston rod is slidably disposed inside the vertical cavity of the mounting block, and the second piston rod is slidably disposed inside the horizontal cavity of the mounting block. The mounting rod is connected through the upper pressure knife. The two rotating sleeves are symmetrically rotated on both sides of the mounting rod, and their bottoms are fixedly connected to the upper end of the first piston rod. The extrusion assembly includes a threaded rod, a pressure plate, and pressure blocks. Two pressure blocks are fixedly connected to the side of the transmission groove and are symmetrically arranged with the mounting groove as the axis. The end of the second piston rod is provided with a threaded groove, and the threaded rod is threaded inside the threaded groove. The pressure plate is fixedly connected to the end of the threaded rod.

[0006] Preferably, the pressure-breaking assembly further includes a first cylinder, side frames, an upper pressure knife, a second cylinder, and a lower pressure knife. The first cylinder is vertically fixedly connected inside the mounting groove and located at one end of the mounting groove. The two side frames are symmetrically fixedly connected to both sides of the mounting groove. One side of the upper pressure knife is rotatably connected to the upper end of the first cylinder, and its middle part is rotatably connected between the two side frames through a rotating shaft. The second cylinder is connected to the first cylinder through an adjusting assembly, with its moving end facing downwards. When the first cylinder moves upwards, the second cylinder moves downwards. One end of the lower pressure knife is rotatably connected to the second cylinder, and its middle part is rotatably connected to both sides of the inner wall of the mounting groove through a rotating shaft.

[0007] Preferably, the adjustment assembly includes a fixed ring, an adjustment plate, and a central shaft. The fixed ring is fixedly sleeved on the moving end of the first cylinder. The two ends of the adjustment plate are rotatably connected to the ends of the fixed ring and the second cylinder, respectively. The central shaft is located in the middle of the adjustment plate and is rotatably connected between the two side frames.

[0008] Preferably, the transmission assembly includes a drive shaft and a transmission belt, with the two drive shafts symmetrically rotatably disposed inside the transmission groove, and the transmission belt sleeved between the two drive shafts.

[0009] Preferably, a guide and push assembly is fixedly connected to the pressure plate, and the guide and push assembly is used to separate the crushed raw material.

[0010] Preferably, the guide pushing assembly includes a vertical shaft, a push plate, and an elastic pad. The vertical shaft is vertically rotatably connected to one side of the two pressure plates that are far apart from each other. One end of the push plate is fixedly connected to the vertical shaft, and the elastic pad is fixedly connected between the push plate and the pressure plate.

[0011] Preferably, the push plate is made of a non-rigid material and forms an angle of 20°-45° with the pressure plate, and the elastic pad is made of a low-deformation elastic material.

[0012] Preferably, a plurality of extrusion strips are fixedly connected to the pressure block, and the plurality of extrusion strips are arranged in parallel on the pressure block and are made of elastic material.

[0013] Preferably, the two transmission components are arranged in an inverted V-shape with a gap in the middle, and the end of the pressing blade is located between the gaps.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The raw material is placed between two transmission components to transfer the component. The material is then crushed by an up-and-down moving upper pressure blade. The downward movement of the upper pressure blade drives the mounting rod and rotating sleeve downwards, causing the first piston rod to slide inside the vertical cavity. This pushes the hydraulic fluid inside the cavity, which in turn pushes the second piston rod, changing its position. The up-and-down moving upper pressure blade drives the linkage component. When the second piston rod moves outwards, it moves the pressure plate, fixing the raw material to be crushed between the pressure plate and the pressure block. The up-and-down moving upper pressure blade is used to adjust the position of the second piston rod, ensuring the pressure plate and pressure block fix the raw material. After crushing is complete, the fixing effect on the raw material is released, ensuring normal transfer of the raw material. This invention can fix the raw material during the crushing process, thus preventing the raw material from shifting during processing and ensuring crushing efficiency. Since the width of each raw material strip may be different, the position of the pressure plate can be adjusted by rotating the threaded rod to ensure the fixing effect of the raw material; After the pressing is completed, the pressure plates on both sides separate from the raw materials. The push plate deflects under the elastic force of the elastic pad, thereby separating the raw material blocks on both sides, avoiding the two raw material blocks from being disconnected, and improving the feeding and limiting of the raw material position. Since the raw material strips are placed in a relatively arbitrary position and will shift after being crushed, a guide and push component is used to limit the position of the raw material in order to ensure that the position of the raw material is limited. The two transmission components are arranged in an inverted V-shape with a gap in the middle. The end of the lower pressure knife is located between the gaps to prevent material fragments from falling onto the transmission belt when pressing material, thus avoiding further wear on the transmission belt. At the same time, it guides the fragments into the mounting groove, facilitating the cleaning of debris. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0019] Reference Figure 1-6 A cutting machine tool for producing and processing nickel-chromium wire, comprising: The crushing assembly 1 includes a processing table 11 and an upper pressure knife 14. The processing table 11 has an installation groove in the middle and a transmission groove on one side. The installation groove and the transmission groove are arranged perpendicularly to each other and form a T shape. Two transmission assemblies 5 are symmetrically arranged inside the installation groove. The upper pressure knife 14 is located directly above the installation groove. The raw material is placed between the two transmission assemblies 5 to transfer the component. The raw material is crushed by the up-and-down moving upper pressure knife 14. Linkage component 2 includes mounting rod 21, rotating sleeve 22, first piston rod 23, second piston rod 24, and mounting blocks 25. The two mounting blocks 25 are L-shaped and symmetrically fixedly connected to both sides of the pressure-breaking component 1. The mounting blocks 25 have L-shaped cavities inside. The first piston rod 23 is slidably disposed inside the vertical cavity of the mounting block 25, and the second piston rod 24 is slidably disposed inside the horizontal cavity of the mounting block 25. The mounting rod 21 is connected through to the upper pressure knife 14. The two rotating sleeves 22 are symmetrically rotated on both sides of the mounting rod 21, and their bottoms are fixedly connected to the upper end of the first piston rod 23. The downward movement of the upper pressure knife 14 will drive the mounting rod 21 and the rotating sleeve 22 to move downward, thereby causing the first piston rod 23 to slide inside the vertical cavity, thereby pushing the hydraulic fluid inside the cavity to push the second piston rod 24, changing the position of the second piston rod 24. The up-and-down movement of the upper pressure knife 14 drives the linkage component 2. The extrusion assembly 3 includes a threaded rod 31, a pressure plate 32, and two pressure blocks 33. Two pressure blocks 33 are fixedly connected to the side of the transmission groove and symmetrically arranged with the mounting groove as the axis. A threaded groove is opened at the end of the second piston rod 24, and the threaded rod 31 is threaded inside the threaded groove. The pressure plate 32 is fixedly connected to the end of the threaded rod 31. When the second piston rod 24 moves outward, it drives the pressure plate 32 to move, thereby fixing the raw material to be crushed between the pressure plate 32 and the pressure blocks 33. This restricts and fixes the position of the raw material during the crushing process. Since the width of each raw material strip may be different, the position of the pressure plate 32 can be adjusted by rotating the threaded rod 31, thus ensuring the fixing effect on the raw material. The up-and-down moving upper pressure knife 14 is used to adjust the position of the second piston rod 24, fixing the raw material between the pressure plate 32 and the pressure blocks 33. After crushing is completed, the fixing effect on the raw material is released, ensuring the normal transfer of the raw material.

[0020] In the embodiments applying the above technical solution, the raw material is placed between two transmission components 5 to transfer the component. The raw material is then crushed by the up-and-down moving upper pressure knife 14. The downward moving upper pressure knife 14 drives the mounting rod 21 and rotating sleeve 22 to move downward, causing the first piston rod 23 to slide inside the vertical cavity, thereby pushing the hydraulic fluid inside the cavity to push the second piston rod 24 and change the position of the second piston rod 24. The up-and-down moving upper pressure knife 14 drives the linkage component 2. When the second piston rod 24 moves outward, it drives the pressure plate 32 to move, thereby fixing the raw material to be crushed between the pressure plate 32 and the pressure block 33. The up-and-down moving upper pressure knife 14 is used to adjust the position of the second piston rod 24, so that the pressure plate 32 and the pressure block 33 fix the raw material. After crushing is completed, the fixing effect on the raw material is released, ensuring the normal transfer of the raw material. This invention can fix the raw material during the crushing process, thereby avoiding the displacement of the raw material during processing and ensuring the efficiency of crushing.

[0021] In this preferred embodiment, the breaking assembly 1 further includes a first cylinder 12, a side frame 13, an upper pressing knife 14, a second cylinder 15, and a lower pressing knife 16. The first cylinder 12 is vertically fixed inside the mounting groove and located at one end of the mounting groove. The two side frames 13 are symmetrically fixed on both sides of the mounting groove. One side of the upper pressing knife 14 is rotatably connected to the upper end of the first cylinder 12, and the middle part is rotatably connected between the two side frames 13 through a rotating shaft. The second cylinder 15 is connected to the first cylinder 12 through an adjusting assembly 4, with the moving end set downwards. When the first cylinder 12 moves upwards, the second cylinder 15 moves downwards. One end of the lower pressing knife 16 is rotatably connected to the second cylinder 15, and the middle part is rotatably connected to both sides of the inner wall of the mounting groove through a rotating shaft. In existing breaking machines, breaking is mostly performed from the top, which can damage the lower processing surface. In order to ensure the breaking effect at a distance, the breaking action is performed by the upper and lower pressing knives, avoiding damage to the bottom side of the processing table 11, while improving the breaking efficiency and speeding up the processing speed. The adjustment assembly 4 includes a fixed ring 41, an adjustment plate 42, and a central shaft 43. The fixed ring 41 is fixedly sleeved on the moving end of the first cylinder 12. The two ends of the adjustment plate 42 are rotatably connected to the ends of the fixed ring 41 and the second cylinder 15, respectively. The central shaft 43 is located in the middle of the adjustment plate 42 and is rotatably connected between the two side frames 13. When the first cylinder 12 drives one end of the upper pressing knife 14 to move upward, it will drive one end of the adjustment plate 42 to move upward, thereby driving one end of the lower pressing knife 16 to move downward through the other end, so that the upper pressing knife 14 and the lower pressing knife 16 can move simultaneously. The transmission assembly 5 includes a drive shaft 51 and a transmission belt 52. The two drive shafts 51 are symmetrically rotated inside the transmission groove, and the transmission belt 52 is sleeved between the two drive shafts 51. The two transmission assemblies 5 can quickly separate the raw material body and the crushed raw material. A guide pushing assembly 6 is fixedly connected to the pressure plate 32. The guide pushing assembly 6 is used to separate the crushed raw material. Since the position of the raw material strip is relatively random when it is placed, and there will be a positional offset after crushing, the position is restricted by the guide pushing assembly 6 in order to ensure the position of the raw material is limited. The guide and push assembly 6 includes a vertical shaft 61, a push plate 62, and an elastic pad 63. The vertical shaft 61 is vertically rotatably connected to the two pressure plates 32 on opposite sides. One end of the push plate 62 is fixedly connected to the vertical shaft 61. The elastic pad 63 is fixedly connected between the push plate 62 and the pressure plate 32. When fixing the raw material strip, the push plate 62 will squeeze the elastic pad 63, thereby deforming the elastic pad 63 and fixing the position of the raw material strip. After the strip is broken, the pressure plates 32 on both sides separate from the raw material. The push plate 62 deflects under the elastic force of the elastic pad 63, thereby separating the raw material blocks on both sides. This avoids the two raw material blocks from being disconnected, improving the feeding and limiting of the raw material position. The push plate 62 is made of a non-rigid material and forms an angle of 20°-45° with the pressure plate 32; the elastic pad 63 is made of a low-deformation elastic material. Multiple extrusion strips 7 are fixedly connected to the pressure block 33. The multiple extrusion strips 7 are arranged in parallel on the pressure block 33 and are made of elastic material to ensure the protection of the pressure block 33. The two transmission components are arranged in an inverted V-shape with a gap in the middle. The end of the lower pressure knife 16 is located between the gaps to prevent material fragments from falling onto the transmission belt 52 when pressing material, thus avoiding further wear on the transmission belt 52. At the same time, it guides the fragments into the installation groove, which facilitates the cleaning of the debris.

[0022] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
