Description

Technical Field

[0001] This invention relates to the field of copper rod cutting technology, and in particular to a copper rod cutting table with equidistant cutting function. Background Technology

[0002] Copper rods are solid, long, columnar metal profiles made from pure copper or copper alloys through plastic processing such as extrusion, drawing, and rolling. They have a regular overall shape and a radial cross-section that is mostly a standard circle. They possess excellent electrical and thermal conductivity and plastic deformation properties. They are often cut into sections according to a set length and used as blanks for processing electrical conductive parts, mechanical connectors, and precision hardware components. They are widely used rod-shaped copper substrates in industrial cutting and processing.

[0003] In the case of batch equidistant cutting of copper bars, the traditional copper bar cutting table is only equipped with a single rigid clamping mechanism and a fixed flat material receiving groove, without a time-sharing positioning compensation structure with rigid-flexible cooperation. During the synchronous feeding of multiple copper bars, due to the combined effects of multiple factors such as the copper bars' own factory dimensional tolerances, mechanical pushing gaps, and inconsistent workpiece placement and fit, there are cumulative length differences between each copper bar. It is difficult to synchronously reach the limit reference to complete the unified calibration, resulting in large equidistant dimensional dispersion of the workpieces after batch cutting, and difficulty in ensuring the cutting accuracy and consistency of the finished product.

[0004] Furthermore, the flat feed trough lacks the ability to adjust for slight workpiece retraction, and sawing debris easily accumulates inside the feed trough and between the sawing gaps, which in turn induces many processing defects such as saw blade jamming, sawing trajectory deviation, and uneven cut, significantly reducing the qualified rate of finished copper rods.

[0005] To address the aforementioned technical shortcomings, a solution is proposed that aims to improve the batch cutting accuracy and operational stability of copper rods by integrating a rigid-flexible composite time-sharing clamping mechanism with a storage-type material support and a self-draining chip structure. Summary of the Invention

[0006] The purpose of this invention is to provide a copper rod cutting stage with equidistant cutting function to solve the above-mentioned technical defects.

[0007] The objective of this invention can be achieved through the following technical solution: a copper rod cutting table with equidistant cutting function, including a cutting platform, the top of the cutting platform having multiple equidistantly distributed V-shaped feeding grooves, and a cutting groove that works with a reciprocating saw blade to cut the copper rod and assists in the self-discharge of debris, the top two sides of the cutting platform are respectively provided with a limit plate and a push plate, the push plate being movably installed to assist in the rapid feeding of copper rods;

[0008] The T-shaped movable plate is located below the corresponding V-shaped feeding trough. Multiple material support rollers for supporting copper rods are staggered on both sides of the top of the T-shaped movable plate. The material support rollers are rotatably connected to a fixed shaft that is fixedly connected to the T-shaped movable plate.

[0009] The U-shaped seat has a clamping block 1 and a clamping block 2 arranged above the corresponding V-shaped feeding groove. The clamping block 1 and the clamping block 2 are located on both sides of the cutting groove. The clamping block 1 is used for rigid clamping of the copper rod, and the clamping block 2, in conjunction with the V-shaped feeding groove, provides a downward flexible clamping of the copper rod to avoid jamming the saw.

[0010] Preferably, the bottom of the cutting platform is provided with a T-shaped groove that communicates with the corresponding V-shaped feeding groove, the T-shaped movable plate is slidably connected to the T-shaped groove, the bottom of the V-shaped feeding groove is provided with a wheel groove for receiving the corresponding material support wheel, and a tension spring is fixedly connected between the T-shaped movable plate and the T-shaped groove.

[0011] Preferably, a pusher frame is slidably connected to the top of the cutting platform, the pusher frame is rotatably connected to the pusher plate, the top of the pusher plate on one side of the rotation point abuts against the pusher frame, and the top of the pusher plate on the other side of the rotation point has a rounded corner.

[0012] Preferably, the limiting plate is slidably connected to the cutting platform, and the limiting plate is threaded with a fixing bolt that abuts against the cutting platform. The bottom of both the limiting plate and the pusher plate is serrated.

[0013] Preferably, a fixed frame is fixedly connected to the top of the cutting platform, and the U-shaped seat is driven to rise and fall by an electric push rod installed on the fixed frame. The U-shaped seat is slidably connected to the fixed frame.

[0014] Preferably, a triangular groove is provided on one side of the bottom of the U-shaped seat, and the top of the clamping block is inclined, with the top of the clamping block slidingly connected to the inclined surface of the triangular groove.

[0015] Preferably, the bottom of the U-shaped seat has a movable groove on the other side that is slidably connected to the corresponding clamping block two, and a spring is fixedly connected between the movable groove and the clamping block two.

[0016] Preferably, the bottom height of the V-shaped feeding trough located below the second clamping block decreases gradually along the copper rod conveying direction.

[0017] Preferably, the cutting groove includes a cutting groove adapted to the thickness of the saw blade, and a triangular unloading groove is provided at the bottom of the cutting groove, and a triangular chip guide block is provided at the bottom of the triangular unloading groove.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) The present invention effectively solves the problems of length deviation and positioning failure when cutting multiple copper rods synchronously and equidistantly by combining a rigid and flexible composite time-sharing clamping structure with rolling feeding: relying on the flexible pre-pressing of clamping block two, and the timing coordination of the subsequent rigid pushing down of clamping block one, it can automatically compensate for the slight length error after multiple copper rods are fed. With the assistance of the rolling of the material support wheel, it can make one end of multiple copper rods uniformly stick to the limiting plate for positioning, eliminating the defects of insufficient cutting size and inconsistent length of a single workpiece; at the same time, the flexible clamping during the cutting process can continuously apply downward pressure, and with the step-by-step sinking V-shaped feeding groove, the free end of the copper rod is slightly offset downward, effectively avoiding saw jamming and saw blade offset, and improving the dimensional accuracy and cut flush consistency of multiple batches of copper rods cut at equal intervals.

[0020] (2) This invention integrates a storage-type material support structure, a self-discharging chip groove, and an adaptive pushing structure. During the feeding stage, the rolling support wheel reduces the pushing resistance of the copper rod. Combined with the deflectable and resetable pushing plate, it achieves rapid material insertion and automatic reset pushing, simplifying the feeding process. During cutting, the material support wheel automatically retracts and hides, allowing the copper rod to effectively resist the V-shaped discharge groove to achieve rigid and stable positioning, preventing workpiece movement caused by cutting vibration. At the same time, the cutting groove formed by the triangular unloading groove and the triangular chip guide block automatically and quickly discharges the cutting chips, avoiding chip accumulation that jams the equipment and affects the processing progress. No additional chip removal structure is required, ensuring stable equipment operation and reducing the probability of failure, while significantly improving the processing efficiency of continuous equidistant cutting of copper rods.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Example 1: Please refer to Figure 1 , Figure 2 and Figures 4-7 As shown, the following solutions address the problems of individual length differences when feeding multiple copper rods simultaneously in batches, resulting in inability to synchronously conform to the limiting reference, large deviations in equidistant cutting dimensions, high resistance in feeding and pushing, and cumbersome and inefficient manual feeding operations:

[0035] In this embodiment, a copper rod cutting table with equidistant cutting function includes a cutting platform 1. The top of the cutting platform 1 is provided with multiple equidistantly distributed V-shaped feeding grooves 11, as well as a cutting groove 12 that works with a reciprocating saw blade to cut the copper rod and assists in the self-discharge of debris. Limiting plates 13 and pushing plates 14 are respectively provided on the top two sides of the cutting platform 1. The pushing plates 14 are movably installed to assist in the rapid feeding of copper rods.

[0036] The T-shaped movable plate 2 is located below the corresponding V-shaped feeding trough 11. Multiple material support rollers 21 for supporting copper rods are staggered on both sides of the top of the T-shaped movable plate 2. The staggered material support rollers 21 can support copper rods of different outer diameters at multiple points, avoiding the copper rods from hanging down at a single point. The whole process is rolled support to eliminate sliding friction. The material support rollers 21 are rotatably connected to the fixed shaft that is fixedly connected to the T-shaped movable plate 2.

[0037] U-shaped seat 3, with clamping block 1 31 and clamping block 2 32 arranged above the corresponding V-shaped feeding groove 11. Clamping block 1 31 and clamping block 2 32 are located on both sides of the cutting groove 12. Clamping block 1 31 is used for rigid clamping of copper rod, and clamping block 2 32 cooperates with V-shaped feeding groove 11 to perform downward flexible clamping of copper rod to avoid sawing.

[0038] The bottom of the cutting platform 1 is provided with a T-shaped groove that communicates with the corresponding V-shaped feeding groove 11. The T-shaped groove is horizontally arranged along the copper rod conveying direction. The inner wall of the groove is smooth to reduce sliding friction resistance. The T-shaped movable plate 2 is slidably connected to the T-shaped groove. The bottom of the V-shaped feeding groove 11 is provided with a wheel groove for the corresponding material support wheel 21 to be received. A tension spring 22 is fixedly connected between the T-shaped movable plate 2 and the T-shaped groove. When the copper rod is pressed down and clamped, the copper rod is pushed down to contact the V-shaped feeding groove 11. The material support wheel 21 is embedded in the corresponding wheel groove and the tension spring 22 is stretched to achieve static rigid clamping and fixing.

[0039] Throughout the feeding process, the support rollers 21 protrude from the bottom of the V-shaped discharge groove 11 to support the copper rod, transforming the sliding friction between the copper rod and the V-shaped discharge groove 11 into rolling friction, which greatly reduces the pushing resistance. In addition, the staggered arrangement of the support rollers 21 is adapted to the shape of the round rod, providing stable support and preventing tipping.

[0040] A pusher frame 15 is slidably connected to the top of the cutting platform 1. The pusher frame 15 is rotatably connected to the pusher plate 14. The top of the pusher plate 14 on one side of the rotation point abuts against the pusher frame 15. When the pusher plate 14 is in the vertical state, it is prohibited from deflecting away from the side of the cutting groove 12. The top of the pusher plate 14 on the other side of the rotation point is provided with a rounded corner. When the pusher plate 14 is in the vertical state, it can deflect away from the side of the cutting groove 12.

[0041] Once one end of the copper rod is placed in the V-shaped feeding groove 11, it is pushed and fed, eliminating the need to lift the entire copper rod for feeding, thus improving the convenience of feeding. The copper rod is pushed to move, and one end of the copper rod abuts against the pusher plate 14, causing the pusher plate 14 to deflect. The copper rod passes under the deflected pusher plate 14 until the other end of the copper rod passes under the pusher plate 14. After the pusher plate 14 separates from the copper rod, it resets its deflection under the action of gravity and abuts against the pusher frame 15 again through the top of the pusher plate 14 to maintain the vertical state, thus realizing the feeding.

[0042] The limiting plate 13 is slidably connected to the cutting platform 1, and the limiting plate 13 is threaded with a fixing bolt that abuts against the cutting platform 1. The sliding installation of the limiting plate 13 is used to adjust the position of the limiting plate 13 to achieve cutting of different cutting lengths. The bottom of both the limiting plate 13 and the pusher plate 14 is serrated, which is used for the effective pushing and limiting of copper rods of different sizes in the V-shaped feeding groove 11.

[0043] The top of the cutting platform 1 is fixedly connected to a fixed frame 33. The U-shaped seat 3 is driven to rise and fall by an electric push rod 34 installed on the fixed frame 33. The U-shaped seat 3 is slidably connected to the fixed frame 33. The electric push rod 34 can precisely control the pressing stroke and pressing speed, ensuring that the clamping sequence progresses steadily and the pressing action is smooth and without impact.

[0044] A triangular groove 35 is provided on one side of the bottom of the U-shaped seat 3. The top of the clamping block 31 is inclined and is slidably connected to the inclined surface of the triangular groove 35. The electric push rod 34 pushes the U-shaped seat 3 to move downward. The clamping block 31 contacts the copper rod of the cutting groove 12. Combined with the sliding connection between the clamping block 31 and the inclined surface of the triangular groove 35 at the bottom of the U-shaped seat 3, the multiple material support rollers 21 roll and support the copper rod, causing the multiple copper rods to move further towards the limiting plate 13. The clamping block 32 and the copper rod slide relative to each other to eliminate the problem of insufficient cutting length caused by the length difference between multiple copper rods, which prevents some copper rods from initially contacting the limiting plate 13. The clamping block 31 is stopped by contacting the vertical side of the triangular groove 35.

[0045] Example 2: Please refer to Figure 3 and Figure 6 As shown, the lack of a rigid-flexible time-sharing clamping compensation structure during the cutting stage, coupled with the absence of adaptive clearance space in the straight material groove, easily leads to saw jamming and skewed cuts due to chip accumulation. The following solutions can be used to address these issues:

[0046] In this embodiment, a U-shaped seat 3 is provided with a clamping block 31 and a clamping block 32 above the corresponding V-shaped feeding groove 11. The clamping block 31 and the clamping block 32 are located on both sides of the cutting groove 12. The clamping block 31 is used for rigid locking of the copper rod, and the clamping block 32 works with the V-shaped feeding groove 11 to achieve flexible clamping of the copper rod in a downward bias, avoiding sawing jamming.

[0047] On the other side of the bottom of the U-shaped seat 3, there is an active groove that slides and connects with the corresponding clamping block 32. A spring 36 is fixedly connected between the active groove and the clamping block 32. The spring 36 can continuously output a constant elastic preload downwards, and the elastic force is uninterrupted throughout the pressing process, which can meet the needs of the copper rod to move down slightly.

[0048] The bottom height of the V-shaped feeding trough 11 located below the clamping block 2 32 gradually decreases along the copper rod conveying direction. The gradually sinking slope provides downward clearance space for the free end of the copper rod. The electric push rod 34 pushes the U-shaped seat 3 to move downward. The clamping block 2 32, combined with the spring 36, first elastically contacts the copper rod between the cutting groove 12 and the limiting plate 13, and applies a real-time downward thrust. After clamping block 1 31, it contacts the copper rod on the other side of the cutting groove 12.

[0049] As the cutting depth increases, the clamping block 32 and spring 36 apply a real-time downward thrust to the copper rod, and the bottom height of the V-shaped feeding groove 11 located below the clamping block 32 gradually decreases along the copper rod conveying direction, causing the free end of the cut copper rod to deflect slightly downward, eliminating the saw blade jamming phenomenon of the copper rod cutting groove 12.

[0050] The groove 12 includes a cutting groove adapted to the thickness of the saw blade. During the process of the reciprocating saw blade cutting the copper rod along the cutting groove, the cutting groove restricts the left and right swing of the saw blade to ensure a straight cut. Combined with the shear stress during the sawing process, the end of the copper rod will tend to curl upward. The clamping block 32 continuously applies downward pressure. In addition, with the guide of the groove bottom which gradually decreases below, the free end of the copper rod being cut will shift slightly downward. The two sides of the saw blade will not be clamped by the rod body, completely eliminating the saw jamming phenomenon.

[0051] Furthermore, a triangular unloading groove is provided at the bottom of the cutting groove, and a triangular chip guide block is provided at the bottom of the triangular unloading groove. The copper chips generated by sawing fall directly into the triangular unloading groove. Relying on the inclined surface of the triangular chip guide block, the chips slide down and are discharged by their own weight, and will not accumulate between the cutting gap and the contact surface of the material groove, thus avoiding chip accumulation that raises the workpiece and jams the saw blade.

[0052] Example 3: Please refer to Figures 1-7 As shown, this invention also proposes a method for using a copper rod cutting table with equidistant cutting function, the specific steps of which are as follows:

[0053] Step 1: One end of the copper rod is placed on the multiple material support rollers 21 in the V-shaped feeding groove 11, and then pushed to move. One end of the copper rod touches the pusher plate 14, causing the pusher plate 14 to deflect. The copper rod passes through the bottom of the deflected pusher plate 14 until the other end of the copper rod passes through the bottom of the pusher plate 14. After the pusher plate 14 separates from the copper rod, it resets and deflects under the action of gravity. One side of the top of the pusher plate 14 touches the pusher frame 15 again to maintain the vertical state. The pusher frame 15 carries the pusher plate 14 to move. The pusher plate 14 pushes the copper rod to move, so that one end of it touches the limiting plate 13, thus completing the fixed-length feeding.

[0054] Step Two: The electric push rod 34 pushes the U-shaped seat 3 to descend. The clamping block 32, combined with the spring 36, first elastically contacts the copper rod between the slot 12 and the limiting plate 13, and applies a real-time downward thrust. The clamping block 31 then contacts the copper rod on the other side of the slot 12. Combined with the continuous descent of the U-shaped seat 3 and the sliding connection between the clamping block 31 and the inclined surface of the triangular groove 35 at the bottom of the U-shaped seat 3, the multiple material support rollers 21 roll and support the copper rod, causing the multiple copper rods to move further towards the limiting plate 13. The clamping block 32 and the copper rod... The relative sliding between the bars eliminates the problem of insufficient cutting length caused by the length difference between multiple copper bars, which prevents some copper bars from initially contacting the limiting plate 13. Then, the relative sliding between the clamping block 31 and the copper bar occurs until the clamping block 31 contacts the vertical side of the triangular groove 35 and is limited. Finally, the descending clamping block 31 and clamping block 32 push the copper bar down to contact the V-shaped feeding groove 11, achieving static rigid clamping and fixing. The material support wheel 21 is embedded in the corresponding wheel groove and stretches the tension spring 22.

[0055] Step 3: The copper rod is cut by a reciprocating saw blade. During the cutting process, the saw blade is vertically stabilized by the cutting groove to maintain the flatness of the copper rod cutting groove 12. At the same time, the generated debris enters the triangular unloading groove and is automatically and quickly discharged by the triangular chip guide block. Meanwhile, as the cutting depth increases, the copper rod is pushed downward in real time by the clamping block 2 32 and the spring 36. The bottom height of the V-shaped discharge groove 11 located below the clamping block 2 32 gradually decreases along the copper rod conveying direction, causing the free end of the cut copper rod to deflect slightly downward, eliminating the saw blade jamming phenomenon of the copper rod cutting groove 12.

[0056] 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.
