Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a wire harness processing and cutting machine. Background Art

[0002] Publication number CN219503650U discloses a cutting machine for wire harness processing, comprising a base plate, a workbench fixedly connected to the base plate, a support plate fixedly connected to the base plate, the workbench and the support plate fixedly connected, a fixed plate fixedly connected to the support plate, a cylinder fixedly connected to the fixed plate, an output end of the cylinder slidably connected to the fixed plate, a connecting plate fixedly connected to the output end of the cylinder, the connecting plate slidably connected to the support plate, a connecting mechanism provided on the connecting plate, and a clamping mechanism provided on the connecting plate. Although this cutting machine can cut wire harnesses by designing a cylinder to drive the cutting knife to move, the horizontal direction of the mounting plate can be limited by plugging the mounting block into the connecting plate, and the vertical direction of the mounting block can be limited by plugging the limit block into the mounting block, thereby achieving the purpose of fixing the mounting plate to the connecting plate. The mounting block can be easily removed from the connecting plate, thereby facilitating the disassembly of the cutting knife. However, with this type of cutting machine, the wire harness is prone to wrinkles and unevenness during the cutting process, which prevents the cutter from smoothly cutting the harness, thus affecting the cutting accuracy and quality. To solve this problem, operators are usually required to manually straighten the harness to keep it flat. However, this method is cumbersome, increases manual operation steps, and reduces overall work efficiency. Therefore, improvements are needed. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] See also Figure 1-5The present invention provides a technical solution: a wire harness processing and cutting machine comprising a frame 1, with legs 13 fixedly mounted on the bottom surface of the frame 1. The legs 13 are symmetrically distributed on the bottom surface of the frame 1 and can be bolted or welded. Bolting offers the advantage of easy disassembly, facilitating subsequent maintenance and repair, and allowing for quick replacement of damaged legs 13. Welding, on the other hand, offers greater strength and stability, ensuring the stability of the machine during long periods of continuous operation. The legs 13 can be made of stainless steel or high-strength engineering plastic. Stainless steel legs 13 offer excellent corrosion resistance and are suitable for use in humid, acidic, or alkaline environments, while high-strength engineering plastics are lightweight and impact-resistant, reducing the weight of the machine and increasing its flexibility in movement and installation. A workbench 2 is fixedly mounted on the inner side of the frame 1 and is attached to the frame 1 by bolts or welding. Bolting offers the advantage of easy adjustment of the workbench 2's position and facilitates removal, repair, or replacement in the event of a machine malfunction. The welding fixation method is more suitable for situations where disassembly is not required for a long time. It can ensure that the workbench 2 does not loosen during long-term operation, thereby ensuring the accuracy and stability of wire harness cutting. The material of the workbench 2 can be aluminum alloy or carbon steel. Aluminum alloy has the advantages of light weight and corrosion resistance, and is particularly suitable for equipment that needs to be frequently moved. Carbon steel has higher strength and wear resistance, can withstand greater pressure and workload, and is suitable for long-term use on large-scale production lines. The top surface of the frame 1 is fixedly mounted with a cylinder 3, which is connected to the frame 1 via a flange. The flange connection can provide higher strength and good sealing, ensuring that the cylinder 3 will not leak or shift under high-pressure operation. At the same time, the output end of the cylinder 3 is connected to the cutting knife 4 via bolts. The bolt connection method not only facilitates the adjustment of the position of the cutting knife 4, but also facilitates quick disassembly and reinstallation when changing the tool, thereby improving the maintenance efficiency of the equipment. Cylinder 3 can be made of high-strength alloy steel or aluminum alloy. Alloy steel cylinder 3 offers exceptional wear resistance and pressure resistance, ensuring long-term stability during high-intensity operation. Aluminum alloy is suitable for applications requiring reduced equipment weight. A bump 5 is fixed to the surface of the cutting blade 4. This bump 5 can be welded or riveted. Welded bumps prevent loosening during high-frequency movement, while riveted attachments facilitate later replacement or maintenance. The bump 5 connects to the rotating rod 6 and, through its movement, drives the coordinated operation of other components. The inner side of the rotating rod 6 is rotatably connected to the bump 5 via a bearing. This bearing effectively reduces friction during rotation, improving the efficiency of the rotating rod 6 and the service life of the equipment. A stopper 7 is fixed to one end of the rotating rod 6. This stopper 7 is welded or bolted to the rotating rod 6. Welding ensures that the stopper 7 does not loosen during high-intensity operation, while bolting facilitates later replacement or maintenance. The primary function of the stopper 7 is to reset the cutting blade 4 by the torsion force of the torsion spring 8.A torsion spring 8 is sleeved on the surface of rotating rod 6. Made of spring steel, this material boasts exceptional fatigue resistance and elasticity, ensuring that torsion spring 8 maintains its elasticity and torque even under prolonged, high-intensity operation without degradation. One end of torsion spring 8 is fixedly connected to stopper 7, while the other end is fixedly connected to protrusion 5. The torsion force of torsion spring 8 automatically resets stopper 7 and rotating rod 6 after cutting blade 4 is pressed downward. This ensures automated operation of the equipment, reduces manual intervention, and improves work efficiency and ease of operation.

[0025] See also Figure 1-5 The surface of the rotating rod 6 is fixedly mounted with a vertical plate 9, which is connected to the rotating rod 6 by bolting or welding. The bolting method makes it easy to replace or adjust the position of the vertical plate 9, while the welding method can ensure that the vertical plate 9 does not loosen during operation, ensuring the accuracy of cutting. The bottom surface of the vertical plate 9 is fixedly mounted with a base plate 10, which is also connected to the vertical plate 9 by bolting or welding. The function of the base plate 10 is to slide horizontally during the downward pressure of the cutting knife 4 to drive the soft pad 12 to flatten the wire harness, preventing the wire harness from wrinkling during cutting and affecting the cutting effect. The side of the base plate 10 is rotatably connected to the pulley 11, which is rotatably connected to the base plate 10 by a ball bearing. The use of the ball bearing can reduce the friction of the pulley 11 when sliding, ensuring the smooth movement of the base plate 10 on the workbench 2, and improving the accuracy and stability of the cutting process. The pulleys 11 are symmetrically distributed on both sides of the base plate 10 to ensure the balance of the base plate 10 and prevent it from offsetting. A soft pad 12 is fixedly mounted on the bottom surface of the base plate 10. Made of natural rubber, this material offers excellent elasticity and wear resistance. This material effectively protects the surface of the wire harness during cutting, keeping it smooth and wrinkle-free, thereby improving cutting precision and quality. Natural rubber also offers excellent aging resistance, ensuring the stability of the device over long-term use.

[0026] Example 2

[0027] See also Figure 4-5The bottom surface of the frame 1 is provided with a pushing mechanism, which includes a wire groove 14 and a cutting groove 15. The wire groove 14 and the cutting groove 15 are both opened on the top surface of the workbench 2. The wire groove 14 is used to place the wire harness to be cut to ensure that the wire harness is in a stable position during the cutting process, while the cutting groove 15 is used to collect the debris generated during the cutting process to prevent the debris from being scattered everywhere and keep the workbench 2 clean. A sliding rod 16 is provided through the bottom surface of the frame 1. The sliding rod 16 is slidably connected to the frame 1. The sliding rod 16 can adopt a guide rail or a ball bearing sliding method to ensure that the sliding process is smooth and there is no jamming. A pressure handle 17 is fixedly installed at one end of the sliding rod 16. The material of the pressure handle 17 can be selected from aluminum alloy or high-strength plastic material. The pressure handle 17 made of aluminum alloy is light and sturdy, suitable for occasions that require frequent operation, while the high-strength plastic has the advantages of light weight and good feel, suitable for long-term operation. A push plate 18 is fixedly mounted on the other end of the slide bar 16. The size of the push plate 18 matches the size of the slot 15, ensuring that debris can be effectively removed from the slot 15. A spring 19 is sleeved on the surface of the slide bar 16. Made of high-strength spring steel, the spring 19 is characterized by its excellent elasticity and fatigue resistance, ensuring that the slide bar 16 quickly returns to its original position after removing debris. One end of the spring 19 is fixedly connected to the pressure handle 17, and the other end is fixedly connected to the frame 1. The spring's rebound force drives the pressure handle 17 and slide bar 16 to reset, eliminating the need for manual reset and further improving the automation and efficiency of the equipment.

[0028] Working principle: Place the wire harness to be cut in the wire groove 14, and then the cylinder 3 drives the cutting knife 4 to move downward. The cutting knife 4 can cut the wire harness at this time. At the same time, during the downward movement of the cutting knife 4, the vertical plate 9 can be squeezed downward. At this time, the vertical plate 9 can drive the bottom plate 10 to move. The bottom plate 10 moves on the workbench 2 through the pulley 11. The bottom plate 10 can drive the soft pad 12 to rub the wire harness. In this way, when the cutting knife 4 cuts, the soft pad 12 can flatten the wire harness, thereby avoiding the wrinkles of the wire harness and affecting the cutting effect. When the cutting knife 4 rises and resets, due to the torsion of the torsion spring 8, the torsion spring 8 can drive the stopper 7 to rotate, and the stopper 7 can then drive the rotary The rod 6 rotates, and the rotating rod 6 then drives the vertical plate 9 and the bottom plate 10 to rotate and reset. At this time, the vertical plate 9 resumes the upright state. The utility model drives the bottom plate 10 and the soft pad 12 to flatten the wire harness during the downward pressure of the cutting knife 4, which can effectively avoid wrinkles in the wire harness during cutting, ensure that the cutting knife 4 can smoothly cut the wire harness, and improve the precision and quality of cutting. During the cutting process, the soft pad 12 flattens the wire harness, so that the wire harness can reach a flat state without manual arrangement, reducing the number of manual operation steps and improving the overall work efficiency. The torsion of the torsion spring 8 is used to realize the automatic reset process after the cutting knife 4 is reset, avoiding manual intervention, so that the equipment can The tool 18 is automatically restored to its original state during continuous operation, which improves the convenience and automation level of operation. When cutting the wire harness, the debris of the wire harness will fall into the cutting groove 15, and the cutting groove 15 can temporarily accommodate the debris to avoid random distribution of the debris. When the cutting groove 15 needs to be cleaned, the staff only needs to pull the pressure handle 17 upward, and the pressure handle 17 can then drive the slide bar 16 and the push plate 18 to move upward, and the push plate 18 then pushes the debris in the cutting groove 15 outward. The spring 19 is provided to facilitate the reset of the push plate 18, and the spring 19 can drive the pressure handle 17 to move downward, and the pressure handle 17 can then drive the slide bar 16 and the push plate 18 to move downward to reset. In the utility model, the design of the cutting groove 15 can temporarily accommodate the debris generated by the wire harness cutting, avoiding the debris from being randomly distributed on the surface of the equipment or the workbench 2, thereby keeping the working area clean and reducing the difficulty of cleaning. The debris in the cutting groove 15 can be quickly pushed out by pulling the pressure handle 17 upward. The cleaning process is simple and convenient, without the need to disassemble the equipment or use additional tools, which greatly reduces the workload of the operator and improves work efficiency. The force of the spring 19 enables the pressure handle 17, the slide rod 16 and the push plate 18 to automatically reset after cleaning is completed, eliminating the manual reset step, avoiding misoperation, and at the same time improving the automation level and ease of use of the equipment.
