Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal material processing equipment, and particularly relates to a copper rod cold rolling device with self-adaptive deformation compensation function. BACKGROUND

[0002] The copper rod cold rolling device is a key equipment for high-precision processing of copper rods through a low-temperature plastic deformation process, and is widely used in the deep processing of copper materials in the fields of wire and cable, electronic components, power transmission, etc. Its core function is to produce controllable plastic deformation of the copper rod through multi-pass precision rolling, thereby significantly improving the mechanical properties (such as strength and hardness) and surface finish of the copper rod, while maximizing the inherent high electrical conductivity and excellent thermal conductivity of copper to meet the stringent requirements of high-end applications on material properties.

[0003] Currently, the mainstream copper rod cold rolling process in the industry adopts four-roll cold rolling technology. However, this technology has obvious limitations in practical application, especially when processing different specifications of copper rod materials, it faces a technical bottleneck that is difficult to break through. Since the existing four-roll cold rolling device lacks effective regulation and control capability for the self-adaptive deformation of the copper rod, when different cross-sectional sizes of copper rods need to be processed, manual replacement of the driven roller disc matching the target size is required to adjust the working width of the roller, so as to meet the size compensation requirements of the copper rod. This manual adjustment method brings a series of problems: on the one hand, the manual replacement of the driven roller disc is a tedious process that requires a lot of time, resulting in a long waiting time for equipment downtime and a significant reduction in effective production time; on the other hand, in the current market environment of increasing small-batch and multi-specification orders, frequent specification switching means that manual roller replacement operations need to be repeated constantly, which seriously disrupts the production rhythm and makes it difficult to guarantee production continuity. Ultimately, the unit capacity efficiency of the equipment is significantly reduced, which not only increases production costs but also makes it difficult to meet the market's requirements for delivery cycle, thereby restricting the efficient development of the copper rod processing industry.

[0004] Based on the above situation, there is an urgent need for a copper rod cold rolling device with self-adaptive deformation compensation function. SUMMARY

[0005] In order to overcome the shortcomings of the existing four-roll cold rolling device, such as lack of self-adaptive deformation regulation and control capability for copper rods, manual replacement of driven roller discs when processing different cross-sectional sizes of copper rods, long equipment downtime, poor production continuity, and low production capacity efficiency, the present application provides a copper rod cold rolling device with self-adaptive deformation compensation function.

[0006] A cold rolling apparatus for copper rods with adaptive deformation compensation function includes a base, on which a main frame is bolted. Hydraulic rods are installed on the upper, lower, left, and right side walls inside the main frame. Active roller assemblies are installed on the telescopic ends of the hydraulic rods on the left and right sides, while guide frames are fixedly connected to the telescopic ends of the hydraulic rods on the upper and lower sides. Each guide frame has a mounting shaft mounted on it via bolts. A rotating ring is provided in the middle of each mounting shaft, and a first driven roller is rotatably connected to each rotating ring. An adjusting frame is vertically slidably connected to each mounting shaft, and a second and third driven roller are horizontally slidably connected to each adjusting frame. The active rollers on the two active roller assemblies and the driven rollers on the two mounting shafts together form a rolling channel through which the copper rod passes to complete the rolling process. Each guide frame is equipped with a replacement component for automatically switching between the first, second, and third driven rollers.

[0007] More preferably, the replacement component includes magnetic rods symmetrically fixed on the adjustment frame, and electromagnetic plates corresponding to the positions of the magnetic rods, which are installed in the guide frame. The electromagnetic plates and the adjacent magnetic rods form a magnetic attraction relationship, and their on / off state is precisely controlled by the control system.

[0008] By controlling the on and off of the electromagnetic plate, an attractive or repulsive force can be generated, driving the magnetic rod to move the adjustment frame and the second and third driven rollers on it precisely in the vertical direction, thereby realizing the switching between the "working position" and the "waiting position".

[0009] More preferably, each adjustment frame is provided with a guide slope on the side near the rotating ring to guide the removal of the driven roller.

[0010] More preferably, each guide frame is equipped with symmetrically distributed electric push rods, and their telescopic parts are fixedly connected to positioning frames. The positioning frames can slide horizontally along the guide frames, and each positioning frame has a slot. The first driven roller, the second driven roller, and the third driven roller are all located in adjacent slots.

[0011] More preferably, each guide frame has an arc-shaped pressure plate fixed to its inner wall to increase the force-bearing surface of the driven roller in the "working position".

[0012] More preferably, the sides of the arc-shaped pressure plates that are close to each other are rotatably connected to evenly distributed shaft rollers.

[0013] More preferably, each positioning bracket has symmetrically distributed screws threaded into the slot, and each screw end is fixed with a pressure block.

[0014] More preferably, each guide frame has a pressure rod switch installed on its inner wall, and a contact block is provided on the magnetic rod near the pressure rod switch. The pressure rod switch is electrically connected to the adjacent hydraulic rod.

[0015] The beneficial effects are as follows: This invention achieves fully automatic and rapid switching of multiple specifications of driven rollers by coordinating an electromagnetically driven lifting unit and an electric push rod-controlled horizontal positioning unit. This design completely replaces the traditional, cumbersome manual roller changing operation, reducing the specification switching time from hours to minutes, and greatly reducing equipment downtime. It is particularly suitable for production needs involving frequent switching of small batches and multiple specifications of orders, ensuring the continuity and efficiency of production rhythm, and significantly improving the overall equipment utilization rate.

[0016] This invention integrates a precise mechanical structure and an intelligent control system. The gap adjustment mechanism on the positioning frame can adaptively compensate for the matching gap between roller groups of different thicknesses and the slots, ensuring no shaking and precise positioning during the switching process. The driven roller in the working position is provided with stable radial support by the arc-shaped pressure plate and the shaft roller on it, and the sliding friction is converted into rolling friction. This not only ensures the stability of the roller and the dimensional accuracy of the copper rod during the rolling process, but also reduces wear and improves the service life and operational reliability of the entire roller system.

[0017] This invention designs a safety interlocking circuit based on a pressure rod switch and a contact block, which fundamentally eliminates the risk of equipment collision caused by the roller not being in place, achieving inherent safety. At the same time, the modular mounting bracket design facilitates the expansion and maintenance of roller specifications. Combined with the adaptive deformation compensation function of four hydraulic rods independently controlled, the device can flexibly and accurately adapt to the rolling requirements of various specifications of copper rods, demonstrating excellent process adaptability and long-term economic efficiency.

Detailed Implementation

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: A cold rolling apparatus for copper rod 101 with adaptive deformation compensation function, such as Figures 1-4 The device includes a base 1, which serves as the main support structure, supporting all components of the entire device and ensuring overall stability. A main frame 2 is bolted to the base 1, providing mounting space and structural support for each functional component. Hydraulic rods 4 are installed on the upper, lower, left, and right side walls inside the main frame 2. The telescopic ends of the hydraulic rods 4 on the left and right sides are equipped with active roller assemblies 3, providing the rotational driving force required for the copper rod 101 during rolling, thus moving the copper rod 101 and completing the rolling process. Guide frames 5 are fixedly connected to the telescopic ends of the hydraulic rods 4 on the upper and lower sides, enabling precise positioning and adaptive adjustment of the driven roller. Mounting shafts 6 are bolted into each guide frame 5, providing a stable mounting base for the driven roller. A rotating ring 7 is provided in the middle of each mounting shaft 6, used to mount and support the driven roller while allowing the driven roller to rotate around it, ensuring smooth operation of the roller during rolling.

[0031] Each rotating ring 7 is rotatably connected to a first driven roller 8, which serves as the driven roller in the initial working state and cooperates with the driving roller assembly 3 to complete the rolling of the copper rod 101. Each mounting frame 6 is vertically slidably connected to an adjusting frame 9, which is used to drive the remaining driven rollers to achieve vertical position raising and lowering, and to switch the waiting and working preparation states of the non-working rollers. Each adjusting frame 9 is horizontally slidably connected to a second driven roller 801 and a third driven roller 802. The first driven roller 8, the second driven roller 801, and the third driven roller 802 represent rollers of different specifications, which are used to adapt to the rolling requirements of copper rods 101 with different cross-sectional dimensions and realize the adaptive deformation compensation of copper rods 101.

[0032] For example, when the size of the cold-rolled copper rod is 1cm×1cm, the third driven roller 802 needs to be selected as the driven roller. In this way, the size between the driving roller and the driven roller can accommodate the passage of a 1cm×1cm copper rod. Similarly, the second driven roller 801 represents the 2cm specification, and the first driven roller 8 represents the 3cm specification.

[0033] A copper rod 101 is provided between the active roller discs on the two active roller assemblies 3 and the first driven roller discs 8 on the two mounting shaft frames 6 to define the rolling processing position of the copper rod 101; each guide frame 5 is provided with a replacement component for automatically switching the first driven roller disc 8, the second driven roller disc 801, and the third driven roller disc 802, so as to realize the rapid switching of driven roller discs of different specifications without the need for manual roller replacement, thereby improving the equipment's ability to adapt to the processing of copper rods 101 of multiple specifications.

[0034] like Figure 4 and Figure 5 As shown, specifically, the replacement component includes magnetic rods 10 symmetrically fixed to the adjustment frame 9. Each guide frame 5 is provided with symmetrically distributed electromagnetic plates 11, which are magnetically attracted to the adjacent magnetic rods 10. They are used to control the lifting and lowering of the magnetic rods 10 and the adjustment frame 9 by generating magnetic force through energization or demagnetizing by de-energization.

[0035] Each adjusting frame 9 is provided with a guide slope 901 on the side near the rotating ring 7. The guide slope 901 is used to guide the removal of the driven roller when the adjusting frame 9 is flush with the rotating ring 7. When it is necessary to remove the driven roller that is fitted on the rotating ring 7, the guide slope 901 can reduce the resistance to the movement of the roller, ensuring that the first driven roller 8 can be smoothly disengaged from the rotating ring 7 and avoiding jamming during roller switching.

[0036] like Figure 6As shown, specifically, each guide frame 5 is equipped with symmetrically distributed electric push rods 13, which are used to provide automated driving force for the horizontal switching of the driven rollers, replacing manual pushing and improving switching efficiency and accuracy; each electric push rod 13 has a positioning frame 12 fixedly connected to its telescopic part, and the positioning frame 12 slides horizontally on the adjacent guide frames 5, which is used to drive the driven roller assembly to move stably.

[0037] Each positioning frame 12 has a slot 121. The first driven roller 8, the second driven roller 801, and the third driven roller 802 are all located in adjacent slots 121. The slots 121 are used to limit and fix the driven roller group to ensure that multiple roller groups can move horizontally synchronously.

[0038] When it is necessary to switch the driven rollers, after the center holes of the first driven roller 8, the second driven roller 801, and the third driven roller 802 are aligned along the horizontal line, the electric push rod 13 can be controlled to drive the positioning frame 12 to move left and right. The positioning frame 12 drives the entire driven roller assembly to move horizontally through the slot 121 until the target driven roller is accurately moved onto the rotating ring 7, completing the automatic switching of the driven rollers and realizing the automation of the switching process, reducing manual intervention.

[0039] like Figure 10 As shown, specifically, each guide frame 5 has a pressure rod switch 18 installed on its inner wall. The pressure rod switch 18 is used as an interlocking device for starting the hydraulic rod 4. Each magnetic rod 10 near the pressure rod switch 18 is provided with a contact block 19. The contact block 19 is used to press the pressure rod switch 18 when the adjustment frame 9 reaches the designated position. The pressure rod switch 18 is electrically connected to the adjacent hydraulic rod 4 to realize the signal linkage between the two.

[0040] The purpose of this design is that the contact block 19 will press the lever switch 18 only when the adjusting frame 9 moves the non-working roller disc to the waiting position, so that the hydraulic rod 4 can receive the start signal and start smoothly; if the adjusting frame 9 does not reach the designated position, the contact block 19 will not trigger the lever switch 18, and the hydraulic rod 4 will not start. This can prevent the non-working roller disc from being stuck between the active roller discs, prevent the active roller assembly 3 from squeezing the non-working roller disc and causing equipment damage when it moves, and ensure the safe operation of the equipment.

[0041] Working principle: Initially, first driven roller discs 8 (3cm specification) are fitted onto the rotating rings 7 of the upper and lower mounting brackets 6. The hydraulic rods 4 on the left and right sides drive the active roller assembly 3 to move inward, so that the active roller discs are tightly fitted with the first driven roller discs 8 on the upper and lower sides, forming a rolling channel suitable for the 3cm×3cm copper rod 101. When the active roller assembly 3 is started, the active roller discs rotate and drive the 3cm×3cm square copper rod 101 to be cold rolled to move longitudinally. The copper rod 101 synchronously drives the first driven roller discs 8 on the upper and lower sides to rotate around the rotating ring 7. Under the coordinated action of the four roller discs, the low-temperature plastic deformation rolling of the copper rod 101 is completed, ensuring the mechanical properties and surface quality of the copper material.

[0042] When processing copper rods 101 with different cross-sectional dimensions, follow the procedure below to switch specifications and avoid production interruptions caused by manual roller changes:

[0043] Preparatory steps: Control the left and right hydraulic rods 4 to drive the active roller assembly 3 to move outward, so that the active roller disk is completely misaligned with the currently working driven roller disk (such as the first driven roller disk 8), eliminating the risk of interference during roller disk switching.

[0044] Switching of the upper driven roller: First, de-energize the upper electromagnetic plate 11, and the magnetic rod 10 loses its magnetic attraction force. The adjustment frame 9 carries the second driven roller 801 (2cm specification) and the third driven roller 802 (1cm specification) and moves down under the action of gravity until they are flush with the rotating ring 7. At this time, the center holes of the three sets of driven rollers are aligned along the horizontal line (the guide slope 901 assists the rollers to move smoothly in the future).

[0045] Next, start the electric push rod 13 to drive the positioning frame 12 to move horizontally: when switching to the 2cm specification, move one position to the left so that the second driven roller 801 is fitted onto the rotating ring 7; when switching to the 1cm specification, move two positions to the left so that the third driven roller 802 is fitted onto the rotating ring 7.

[0046] Subsequently, the upper electromagnetic plate 11 is re-energized, and the magnetic rod 10 drives the adjustment frame 9 and the non-working roller to move up to the waiting position. At this time, the contact block 19 on the magnetic rod 10 presses the pressure rod switch 18, and the hydraulic rod 4 obtains the start permission.

[0047] Switching of the lower driven roller: First, the lower electromagnetic plate 11 is energized, generating a magnetic force that repels the magnetic rod 10. This drives the adjusting frame 9 to move the two sets of driven rollers upwards against gravity until they are flush with the rotating ring 7, ensuring that the center holes of the three sets of rollers are aligned. Next, the operation of the electric push rod 13 driving the positioning frame 12 to move is repeated to complete the switching of the corresponding specification driven rollers (second driven roller 801, third driven roller 802). Then, the lower electromagnetic plate 11 is de-energized, the adjusting frame 9 moves the non-working rollers downwards to reset, the contact block 19 triggers the pressure rod switch 18, and the hydraulic rod 4's start-up permission is activated.

[0048] Example 2: As Figure 7 andFigure 8 As shown, specifically, each guide frame 5 has an arc-shaped pressure plate 14 fixed to its inner wall, which is used to apply lateral pressure to the driven roller in the working position, increase the force-bearing surface of the driven roller, prevent the driven roller from tilting due to uneven force during rolling, ensure the precise matching between the driven roller and the driving roller, and improve the rolling accuracy of the copper rod 101.

[0049] The curved plates 14 are rotatably connected to evenly distributed shaft rollers 15 on their adjacent sides. The curved surface of the driven roller disc contacts the adjacent shaft roller 15. The shaft roller 15 is used to convert the sliding friction between the driven roller disc and the curved plate 14 into rolling friction, which significantly reduces the friction between the two and ensures that the driven roller disc can rotate flexibly without affecting the normal rolling rhythm of the copper rod 101.

[0050] like Figure 9 As shown, specifically, each positioning frame 12 is threaded with symmetrically distributed screws 16 at the slot 121, and each end of the screw 16 is fixed with a pressure block 17. The pressure block 17 is used to contact the surface of the driven roller and fill the gap between the slot 121 and the driven roller assembly.

[0051] When the positioning frame 12 moves the driven roller assembly, if a thinner driven roller is used, resulting in the overall thickness of the roller assembly being less than the size of the slot 121, roller misalignment and displacement problems may occur. In this case, screw 16 can be turned to move the pressure block 17 inward and outward until the pressure block 17 is in close contact with the driven roller, ensuring that the positioning frame 12 moves the driven roller assembly smoothly and accurately to the target position through the slot 121, thus ensuring the accuracy of roller switching.

[0052] Since the upper and lower mounting brackets 6 are detachably connected to the guide frame 55 by bolts, it is convenient for the expansion and maintenance of the roller plate specifications. When it is necessary to process a 0.5cm copper rod 101, the detachable feature of the mounting bracket 6 and the gap compensation structure are used to complete the switch. The specific process is as follows: remove the fixing bolts between the mounting bracket 6 and the guide frame 5, remove the mounting bracket 6, replace the third driven roller plate 802 (1cm specification) on the adjustment frame 9 with a 0.5cm thick driven roller plate (referred to as the fourth driven roller plate), and then fix the mounting bracket 6 back to the guide frame 5 with bolts.

[0053] Because the thickness of the fourth driven roller is reduced, the overall thickness of the driven roller assembly is less than the inner width of the slot 121 of the positioning frame 12. Tighten the screw 16 at the slot 121 to drive the pressure block 17 to move inward to fit the surface of the roller assembly, fill the gap, and ensure that the positioning frame 12 drives the roller assembly to move without skewing or misalignment.

[0054] Whenever the replacement of the thinner driven roller results in the roller assembly thickness being less than the inner width of the slot 121, the position of the pressure block 17 is adjusted by screw 16 to ensure that the roller assembly fits tightly with the slot 121 and to ensure accurate movement.

[0055] When the driven roller is in operation, it contacts the shaft roller 15 on the arc-shaped pressure plate 14. The shaft roller 15 converts sliding friction into rolling friction, ensuring smooth rotation of the roller. At the same time, the arc-shaped pressure plate 14 increases the force-bearing surface of the driven roller, reduces the force load on the hollow mounting shaft 6, avoids damage to the mounting shaft 6 due to excessive force, and improves rolling stability.

[0056] If the adjustment frame 9 does not move to the designated waiting position, the contact block 19 does not trigger the pressure switch 18, and the hydraulic rod 4 remains locked. This prevents the active roller assembly 3 from squeezing the non-working roller disc when it moves inward, thus avoiding equipment damage and achieving foolproof operation and safety protection.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
