Description

Technical Field

[0001] This invention relates to the field of copper rod cutting technology, specifically to an automated fixed-length copper rod cutting device. Background Technology

[0002] Copper rods are widely used in electronic components, machinery manufacturing and other fields. Fixed-length cutting is a key step before the precision processing of copper rods. At present, the copper rod processing mode is mostly to feed the copper rod to the positioning device, and the cutting device cuts one or more copper rods at the same time, and then unloads them in a unified manner, and completes a large number of copper rod cuttings in a cycle.

[0003] Existing equipment typically only supports a single length setting and can only cut copper rods of the same specification. When switching cutting lengths, it is necessary to stop the machine to set parameters and then cut again. However, for small batch orders, repeated machine stops are required for debugging, increasing labor costs. At the same time, when cutting short-length copper rods, in order to maintain production efficiency, the cut long copper rods are used for secondary processing. This not only increases material waste but also reduces the precision of the workpiece end face. Furthermore, existing copper rod cutting machines that can only cut one length are relatively simple in function and lack versatility, making it difficult to meet the needs of various orders. Summary of the Invention

[0004] This invention proposes an automated fixed-length copper rod cutting device to solve the problem that existing copper rod cutting machines cannot meet the needs of cutting copper rods of various specifications simultaneously.

[0005] The technical solution of the present invention is as follows: An automated fixed-length cutting device for copper bars includes a frame and a cutting machine, the cutting machine being slidably connected to the frame. It also includes a feeding rack, a discharging rack, a clamping component, and a length-fixing mechanism. The feeding rack is fixedly connected to the frame and has multiple feeding slots. The discharging rack is rotatably connected to the frame and has multiple discharging slots, each corresponding to a feeding slot. The copper bar can slide from the feeding slot into the discharging slot. The clamping component is mounted on the frame, and both the clamping component and the cutting machine are equipped with... The clamping component, positioned between the loading rack and the unloading rack, clamps and secures the copper rods on both racks. This allows the cutting machine to cut multiple copper rods. A length-fixing mechanism is located at the end of the unloading rack furthest from the cutting machine. Uncut copper rods slide in the unloading groove and stop sliding when they contact the length-fixing mechanism. The length-fixing mechanism includes a guide frame and multiple flexible contact components. These flexible contact components are slidably connected to the guide frame and stop sliding when the copper rod contacts them. The rotating connection of the unloading rack allows for simultaneous unloading of the cut copper rod segments. Loading occurs when the unloading rack rotates to a horizontal angle. After cutting, the rack rotates and tilts, allowing the copper rods to slide and complete unloading. During copper rod transport, the length-fixing mechanism limits the individual lengths of multiple copper rods, ensuring uniform cutting.

[0006] Both the loading trough and the unloading trough are fixedly equipped with inclined support plates. When the copper rod slides in the loading trough and the unloading trough, it can roll to the lower side of the inclined support plate. Only one diameter of copper rod can be cut at a time in the multiple loading troughs and unloading troughs. Copper rods of different specifications can also roll to the lower side on the inclined support plate, so that this application can meet the processing of copper rods of various specifications. A drive cylinder is provided on the frame, and its output end is rotatably connected to the unloading frame. When the output end of the drive cylinder shortens, it can drive the unloading frame to tilt and rotate downwards.

[0007] The clamping component includes a frame-shaped pressing frame and a pressing plate. The frame-shaped pressing frame is longitudinally slidably disposed between the loading rack and the unloading rack. When the frame-shaped pressing frame moves downward, it can contact the copper rods on the loading rack and the unloading rack. The pressing plate is fixedly connected to the side of the frame-shaped pressing frame that is in contact with the copper rod. When the pressing plate clamps the copper rod, the copper rod is in contact with the loading rack wall, the pressing plate, and the inclined support plate in the loading groove, and the same applies in the unloading groove. This three-way clamping method can be satisfied for copper rods of various specifications. The frame-shaped pressing frame is configured as two U-shaped frames, driven by the output end of the drive cylinder four on the frame. The frame-shaped pressing frame slides downward and contacts the copper rod through the pressing groove, simultaneously clamping and fixing the copper rods on both sides of the cutting machine.

[0008] Both the loading rack and the unloading rack have pressing grooves near the cutting machine. The pressing grooves extend through multiple loading or unloading grooves. When the pressing sheet moves with the frame-shaped pressing frame and comes into contact with multiple copper rods, the copper rods are fixed and clamped. At this time, the cutting machine can cut the copper rods.

[0009] The length-fixing mechanism further includes a positioning frame and secondary positioning components. The positioning frame is fixedly installed at the end of the unloading frame away from the cutting machine. The guide frame is slidably connected to the positioning frame, and multiple secondary positioning components are provided on the guide frame. The flexible contact assembly is slidably connected to the secondary positioning components. A second drive cylinder is provided on the positioning frame, which can drive the guide frame to slide on the positioning frame.

[0010] The guide frame slides on the positioning frame, causing multiple flexible contact components to slide, thus performing a primary adjustment to the copper rod length. The flexible contact components can also slide on the secondary positioning member, performing a secondary adjustment to the copper rod length. A third drive cylinder is installed on the secondary positioning member, with its output end connected to the abutment member. The distance between the abutment member and the secondary positioning member can be adjusted via the output end of the third drive cylinder. Both the sliding of the guide frame and the sliding of the flexible contact components can adjust the position of the abutment plate, thereby changing the copper rod length setting. The sliding of the guide frame can be considered a large-range adjustment of the copper rod length, while the sliding of the flexible contact components provides a small-range adjustment; the combination of these two actions completes the copper rod length adjustment.

[0011] The flexible contact assembly includes a guide rod, an abutment, an abutment plate, and an elastic component. The guide rod is slidably connected to the secondary positioning component, the abutment is fixedly connected to the guide rod, and the abutment plate is rotatably connected to the abutment on the side near the cutting machine. An elastic component is provided between the abutment plate and the abutment. When the copper rod slides and contacts the abutment plate, it can push the abutment plate to rotate and contact the abutment, at which point the copper rod stops sliding.

[0012] After the cutting machine finishes cutting the copper rod, the abutment can slide away from the cutting machine and separate from the copper rod, and the unloading rack can rotate and tilt to allow the copper rod to slide out of the unloading groove.

[0013] The working principle and beneficial effects of this invention are as follows: 1. In this invention, by setting a guide frame and a flexible contact component, the guide frame can be adjusted to slide and adjust the distance between itself and the cutting machine. The flexible contact component slides on the guide frame. The length of multiple copper rods can be limited by two sliding adjustments. After multiple copper rods are loaded, the processing of copper rods of various specifications can be completed simultaneously by adjusting the length of each copper rod accordingly. 2. In this invention, by setting a guide frame, multiple flexible contact components can be slid simultaneously to perform primary adjustment of the copper rod length. Secondary adjustment of the copper rod length can be performed by sliding the flexible contact components on the secondary positioning frame. The positions of the multiple flexible contact components are adjusted individually. Sliding stops when the copper rod abuts against the flexible contact component, thus determining the length. The length of each copper rod can be customized. Simultaneously, the rotating unloading frame allows multiple copper rods to be unloaded simultaneously. Compared to traditional fixed-length copper rod cutting machines, this application can achieve unified cutting of multiple copper rods after each fixed-length cutting, improving cutting efficiency while further saving materials.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-8 As shown in the figure, this embodiment proposes an automated fixed-length cutting device for copper rods, including a frame 1 and a cutting machine 2. The cutting machine 2 is slidably connected to the frame 1. It also includes a feeding rack 3, a discharging rack 5, a clamping component, and a length-fixing mechanism. The feeding rack 3 is fixedly connected to the frame 1 and has multiple feeding slots 4. The discharging rack 5 is rotatably connected to the frame 1 and has multiple discharging slots 6, which correspond one-to-one with the feeding slots 4. The copper rods can slide from the feeding slots 4 into the discharging slots 6. The clamping component is set on the frame 1 and is located between the feeding rack 3 and the discharging rack 5, along with the cutting machine 2. The clamping component can clamp and fix the copper rods on the feeding rack 3 and the discharging rack 5. At this time, the cutting machine 2 can cut multiple copper rods. The length-fixing mechanism is located at the end of the discharging rack 5 away from the cutting machine 2. The uncut copper rods slide in the discharging slots 6. When the copper rod contacts the fixed-length mechanism, it stops sliding. The fixed-length mechanism includes a guide frame 7 and multiple flexible contact components. The flexible contact components are slidably connected to the guide frame 7. When the copper rod contacts the flexible contact component, it stops sliding. The rotating connection of the unloading rack 5 can simultaneously unload the cut copper rod segments. When the unloading rack 5 rotates to a horizontal angle, it is loaded. After cutting, it rotates and tilts, so that the copper rod slides to complete the unloading. When the copper rod is being transported, the fixed-length mechanism completes the length limitation of multiple copper rods and completes the cutting uniformly. In this application, both the loading groove 4 and the unloading groove 6 are provided with five. When the five copper rods slide from the loading groove 4 to the unloading groove 6, the cutting machine 2 completes the cutting of multiple copper rods when it slides. A drive cylinder 18 is provided on the frame 1. The output end is rotatably connected to the unloading rack 5. When the output end of the drive cylinder 18 is shortened, it can drive the unloading rack 5 to tilt and rotate downwards.

[0019] like Figure 5 As shown, inclined support plates 8 are fixedly installed in both the feeding groove 4 and the unloading groove 6. When the copper rod slides in the feeding groove 4 and the unloading groove 6, it can roll to the lower side of the inclined support plate 8. Only one type of copper rod can be cut at the same time in multiple feeding grooves 4 and unloading grooves 6. Copper rods of different specifications can also roll to the lower side on the inclined support plate 8, so that this application can meet the processing of copper rods of various specifications.

[0020] like Figure 4As shown, the pressing component includes a frame-shaped pressing frame 9 and a pressing plate 10. The frame-shaped pressing frame 9 is longitudinally slidably disposed between the upper feeding frame 3 and the lower feeding frame 5. When the frame-shaped pressing frame 9 moves downward, it can contact the copper rods on the upper feeding frame 3 and the lower feeding frame 5. The pressing plate 10 is fixedly connected to the side of the frame-shaped pressing frame 9 that is in contact with the copper rods. Figure 5 As shown, when the pressing plate 10 presses the copper rod, the copper rod is in contact with the wall of the feeding groove 4, the pressing plate 10 and the inclined support plate 8 in the feeding groove 4. The same applies in the unloading groove 6. Copper rods of various specifications can meet this three-way clamping method. The frame-type pressing frame 9 is set as two U-shaped frames, which are driven by the output end of the drive cylinder 21 set on the frame 1. The feeding frame 3 and the unloading frame 5 pass through the two U-shaped frames respectively. The cutting machine 2 is located between the two U-shaped frames. The frame-type pressing frame 9 slides down and can contact the copper rod through the pressing groove 11. At the same time, it presses and fixes the copper rods on both sides of the cutting machine 2. After the copper rods on both sides of the cutting machine 2 are fixed, slippage or vibration during cutting can be avoided.

[0021] like Figure 4 As shown, pressing grooves 11 are provided on both the loading rack 3 and the unloading rack 5 near the cutting machine 2. The pressing grooves 11 pass through multiple loading grooves 4 or unloading grooves 6. When the pressing sheet 10 moves with the frame-shaped pressing frame 9 and comes into contact with multiple copper rods, the copper rods are fixed and clamped. At this time, the cutting machine 2 can cut the copper rods.

[0022] like Figures 6-7 As shown, the length-fixing mechanism also includes a positioning frame 12 and secondary positioning components 13. The positioning frame 12 is fixedly installed at the end of the unloading frame 5 away from the cutting machine 2. The guide frame 7 is slidably connected to the positioning frame 12. Multiple secondary positioning components 13 are provided on the guide frame 7. Each secondary positioning component 13 is a guide frame 7 with a flexible contact component that slides. The multiple secondary positioning components 13 are independently configured, such as... Figure 6 As shown, during the processing of copper rods, each secondary positioning frame 12 and the flexible contact component extend into a feeding groove 6. The flexible contact component is slidably connected to the secondary positioning component 13. A drive cylinder 19 is provided on the positioning frame 12, which can drive the guide frame 7 to slide on the positioning frame 12.

[0023] like Figure 1 and Figure 6As shown, the guide frame 7 slides on the positioning frame 12, which can drive multiple flexible contact components to slide, performing a primary adjustment of the copper rod length setting. The flexible contact components can slide on the secondary positioning component 13, performing a secondary adjustment of the copper rod length setting. A drive cylinder 20 is provided on the secondary positioning component 13. The output end of the drive cylinder 20 is connected to the abutment component 15. The distance between the abutment component 15 and the secondary positioning component 13 can be adjusted through the output end of the drive cylinder 20. Both the sliding of the guide frame 7 and the sliding of the flexible contact components can adjust the position of the abutment plate 16, thereby changing the setting of the copper rod length. The sliding of the guide frame 7 can be regarded as a large-range adjustment of the copper rod length, while the sliding of the flexible contact components is a small-range adjustment. The combination of the two completes the adjustment of the copper rod length.

[0024] like Figure 8 As shown, the flexible contact assembly includes a guide rod 14, an abutment member 15, an abutment plate 16, and an elastic component 17, as... Figures 7-8 As shown, the guide rod 14 is slidably connected to the secondary positioning member 13, the abutment member 15 is fixedly connected to the guide rod 14, and the abutment plate 16 is rotatably connected to the abutment member 15 on the side near the cutting machine 2. An elastic member 17 is provided between the abutment plate 16 and the abutment member 15. When the copper rod slides and contacts the abutment plate 16, it can push the abutment plate 16 to rotate until it contacts the abutment member 15. At this time, the copper rod stops sliding. In this application, the elastic member 17 is set as a spring, which is used to push the abutment plate 16 to rotate. When the copper rod contacts the abutment plate 16, it can push the abutment plate 16 to rotate. When the abutment plate 16 rotates to fit with the abutment member 15, the copper rod stops sliding. The rotation of the abutment plate 16 can act as a shock absorber for the copper rod, preventing the copper rod from having an error in its length between the abutment plate 16 and the cutting machine 2 due to the back vibration.

[0025] After the cutting machine 2 finishes cutting the copper rod, the abutment 15 can slide away from the cutting machine 2 and separate from the copper rod. The unloading rack 5 can rotate and tilt so that the copper rod slides out of the unloading groove 6. After the copper rod slides out of the unloading groove 6, it can be collected separately to avoid mixing copper rods of different lengths.

[0026] In this embodiment, the copper rod slides continuously in the feeding groove 4 and the unloading groove 6. After the guide frame 7 slides and is positioned on the positioning frame 12, the abutment 15 slides on the secondary positioning member 13 for secondary positioning, so that the length of the copper rod is fixed in each unloading groove 6. When the copper rod slides in the unloading groove 6 and contacts the abutment plate 16, it pushes the abutment plate 16 to rotate and fit with the abutment 15. At this time, the frame-type pressing frame 9 presses and fixes the copper rod in the pressing groove 11. The inclined support plate 8 can clamp and fix copper rods of various sizes. At this time, the cutting machine 2 moves to cut multiple copper rods in sequence. After the cutting is completed, the unloading frame 5 rotates to unload multiple copper rods.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
