Abstract
Description
Technical Field
[0001] This invention relates to the field of mudguard processing technology, specifically to a rolling equipment for processing front and rear metal mudguards for electric vehicle wheels. Background Technology
[0002] The front and rear metal mudguards of electric vehicle wheels are mostly made of metal steel strips through rolling and bending processes. The industry generally uses bending and rolling equipment to complete the feeding, rolling and shaping processes of the steel strip. The equipment is equipped with main rolling wheels and auxiliary pressing and shaping wheels to work together to complete the rolling forming. In addition, the processed steel strip is limited and guided by the limiting shaft roller above the oil tank and passes through the inside of the oil tank. The oil stored in the oil tank is used to lubricate the steel strip as a whole, thereby reducing rolling friction loss and improving the smoothness of the plate surface.
[0003] During continuous conveying and rolling of existing metal steel strips, the lubricating grease adhering to the surface is easily affected by the conveying traction force and flows naturally to both sides of the steel strip edge. Excess lubricating grease on the upper end of the steel strip tends to spread and drip onto the lower end of the steel strip, resulting in uneven grease adhesion between the upper and lower end of the steel strip. Uneven grease distribution can cause insufficient lubrication in some areas of the steel strip, which can easily lead to slippage between the wheel and the steel strip during rolling, as well as scratches on the metal plate surface. Furthermore, excessive local grease accumulation can cause uneven rolling indentation depth and deviations in bending curvature. At the same time, metal steel strips of different widths have different degrees of floating during rolling, which affects the regularity of the metal mudguard forming of electric vehicles and the consistency of batch processing.
[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention
[0005] The purpose of this invention is to provide a rolling equipment for processing front and rear metal mudguards for electric vehicle wheels, so as to solve the problems mentioned in the background art. The technical solution of this invention provides a solution that is significantly different from the existing technology, which is too simplistic.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a rolling equipment for processing front and rear metal mudguards for electric vehicle wheels, comprising a bending machine body, wherein a main rolling wheel and an auxiliary pressure forming wheel are installed at the output end of the bending machine body, an oil tank is provided on one side of the bending machine body, a limit roller is rotatably connected in the middle of the oil tank, and a grease collection assembly is provided on one side of the bending machine body for collecting grease on the upper surface of the steel strip; The grease collection assembly includes a support rod installed on one side of the bending machine body. A first spring is sleeved on the outer wall of the support rod. A transmission rod is slidably connected to both ends of the support rod. Both ends of the first spring are connected to the transmission rod. A limit wheel is rotatably connected to the middle of the transmission rod. A drive wedge is installed on the upper end of the transmission rod. A steel belt stabilizing component is provided on one side of the grease gathering assembly to stabilize the state of the steel belt during the grease gathering process.
[0007] Preferably, the grease gathering assembly further includes a support frame mounted on the upper end of the support rod. The support frame has a concave structure design, and two drive shafts are rotatably connected to the upper end of the support frame.
[0008] Preferably, a drive groove is provided on the outer wall of the upper end of both drive shafts, the drive groove is in the shape of a spring curve, and a second spring is movably sleeved on the outer wall of both drive shafts.
[0009] Preferably, the lower ends of the two second springs are connected to the support frame, and the upper ends of the two second springs are connected to a drive plate. Driven wedges are installed on the lower ends of both sides of the drive plate.
[0010] Preferably, the inclined surface of the driven wedge block is in contact with the inclined surface of the driving wedge block, and the driving plate has a limiting groove corresponding to the driving shaft, and the limiting groove is movably sleeved on the outer wall of the driving shaft.
[0011] Preferably, a drive block is installed on the inner wall of the limiting groove corresponding to the drive groove, the drive block is slidably connected to the drive groove, and a gathering plate is installed on the lower end of the drive shaft.
[0012] Preferably, the steel strip stabilizing assembly includes a rectangular groove formed on the upper side of one end of the gathering plate, and two protrusions integrally extending from one side of the support frame. Each protrusion is laterally slidably connected to a limiting guide rod at its center, and a stabilizing roller is rotatably connected to the limiting guide rod near the middle side.
[0013] Preferably, the end of the limiting guide rod near the stabilizing roller is connected to an L-shaped frame, and a force-bearing shaft is installed at the lower end of the side of the L-shaped frame away from the limiting guide rod. The force-bearing shaft is movably inserted into a rectangular groove.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a limiting wheel that adaptively presses against the steel strip according to its width, causing the drive wedge to move in conjunction with the driven wedge to convert the lateral displacement into the vertical lifting and lowering of the drive plate. The drive block slides along the curved drive groove, driving the drive shaft to rotate and adjusting the V-shaped inclination angle of the gathering plate. This allows for adjustment of the size of the grease gathering port and the end opening according to the width of the steel strip, adapting to the actual working conditions of wide steel strips with small gathering openings and large ends, and narrow steel strips with large gathering openings and small ends. It gathers the flowing grease on both sides of the upper surface of the steel strip to the central area. During subsequent rolling, the grease will be evenly distributed under the pressure of the main rolling wheel and the auxiliary pressure forming wheel, avoiding grease overflow and dripping that causes uneven lubrication on the upper and lower end faces. This improves rolling slippage, surface scratches, uneven indentation depth, and bending arc deviation.
[0015] 2. This invention utilizes the deflection of the gathering plate to drive the rectangular groove extrusion force shaft, which in turn drives the L-shaped frame to slide laterally. Combined with the characteristics of wide steel strips exhibiting small deformation fluctuations and narrow steel strips exhibiting large deformation fluctuations, this invention achieves adaptive adjustment for wide steel strips with short strokes and small-amplitude material stabilization, and narrow steel strips with long strokes and large-range compaction and limiting. The stabilizing roller always avoids the grease gathering area in the middle of the steel strip, only performing limiting pressure on the outer side of the steel strip, without touching or disturbing the already collected central lubricating grease, ensuring that the concentrated distribution of grease is not disrupted. After rolling, each component relies on the elastic reset of the first and second springs to quickly restore its initial limiting and gathering state. This can meet the needs of continuous rotation rolling operations for steel strips of different widths, improving the rolling regularity and batch processing dimensional consistency of electric vehicle metal mudguards.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0019] Please see Figures 1-8 The present invention provides a technical solution: a rolling equipment for processing front and rear metal mudguards for electric vehicle wheels, including a bending machine body 1, a main rolling wheel 2 and an auxiliary pressure shaping wheel 3 installed at the output end of the bending machine body 1, an oil tank 4 provided on one side of the bending machine body 1, and a limit shaft roller 5 rotatably connected in the middle of the oil tank 4; When the equipment is powered on and in standby mode, the metal strip of the electric vehicle mudguard to be rolled is first guided around the limiting roller 5 above the oil tank 4 to complete the initial guiding and limiting, and then the end of the steel strip is inserted into the rolling gap between the main rolling roller 2 and the auxiliary pressure forming roller 3; wherein, the limiting roller 5 can guide the steel strip into the oil tank 4.
[0020] In one embodiment of the present invention, a grease gathering assembly is provided on one side of the bending machine body 1 for gathering grease on the upper surface of the steel strip; the grease gathering assembly includes a support rod 601 installed on one side of the bending machine body 1, a first spring 602 sleeved on the outer wall of the support rod 601, a transmission rod 603 slidably connected to both ends of the support rod 601, the first spring 602 connected to both ends of the transmission rod 603, a limit wheel 604 rotatably connected to the middle of each transmission rod 603, and a drive wedge 605 installed on the upper end of each transmission rod 603; the grease gathering assembly also includes a support frame 606 installed on the upper end of the support rod 601, the support frame 606 having a concave structure design, and two drive shafts 607 rotatably connected to the upper end of the support frame 606; the two drive shafts 607 The upper outer wall of each drive shaft 607 is provided with a drive groove 608, which is in the shape of a spring curve. The outer walls of the two drive shafts 607 are movably fitted with second springs 609. The lower ends of the two second springs 609 are connected to the support frame 606. The upper ends of the two second springs 609 are connected to a drive plate 610. The lower ends of both sides of the drive plate 610 are equipped with driven wedges 611. The inclined surfaces of the driven wedges 611 are in contact with the inclined surfaces of the drive wedges 605. The drive plate 610 is provided with a limiting groove 612 corresponding to the drive shaft 607. The limiting groove 612 is movably fitted on the outer wall of the drive shaft 607. The inner wall of the limiting groove 612 is equipped with a drive block 613 corresponding to the drive groove 608. The drive block 613 is slidably connected to the drive groove 608. The lower ends of the drive shafts 607 are all equipped with a converging plate 614. At the same time, the steel strip is inserted laterally into the clamping area between the two sets of limit wheels 604, so that the upper surface of the steel strip is in contact with the lower end face of the gathering plate 614, completing the material insertion and positioning operation before the steel strip is processed. The internal drive mechanism of the bending machine body 1 is started, which drives the output end of the bending machine body 1 to rotate. The rotating output end drives the main rolling wheel 2 and the auxiliary pressure forming wheel 3 to rotate synchronously in opposite directions. The rotating main rolling wheel 2 and the auxiliary pressure forming wheel 3 extrude, bend and roll the metal strip passing between them to complete the basic outline forming of the electric vehicle metal mudguard. Among them, the continuous bending, rolling and shaping of the steel strip is achieved by the counter-rotation of the two wheels. When processing metal strips with a large width, the two sides of the wide strip push outwards against the limiting wheels 604. After being squeezed by the strip, the limiting wheels 604 drive the transmission rod 603 to slide laterally outwards along the support rod 601. The sliding transmission rod 603 stretches the first spring 602 sleeved on the outer wall of the support rod 601. At the same time, the drive wedge 605 fixed at the upper end of the transmission rod 603 moves outwards synchronously with the transmission rod 603. The outwardly moving drive wedge 605 abuts against and squeezes the driven wedge 611 through its own inclined surface. The driven wedge 611 is driven by the inclined squeezing force to make the drive plate 610 move vertically upwards. The drive plate 610 slides upwards along the outer wall of the drive shaft 607 through the limiting groove 612 it has opened. At the same time, it pulls upwards to stretch and deform the second spring 609 sleeved on the outer side of the drive shaft 607. In this way, the lateral displacement is converted into the vertical lifting and lowering of the drive plate 610 by the inclined surface transmission. When the drive plate 610 moves upward, the drive block 613 installed on the inner wall of the limiting groove 612 moves upward along with it. The drive block 613 slides along the drive groove 608, which is in the shape of a spring curve on the outer wall of the drive shaft 607. During the sliding process, the drive shaft 607 is driven to rotate. The lower end of the rotating drive shaft 607 is fixedly connected to the gathering plate 614, which in turn drives the gathering plate 614 to deflect and rotate synchronously. After the two gathering plates 614 deflect synchronously, they form a figure-eight arrangement. The larger end of the figure-eight opening of the gathering plate 614 is opposite to the direction of steel belt conveying. The wider the steel belt, the smaller the opening of the grease gathering port at the front end of the two gathering plates 614 and the larger the opening at the rear end. During the steel belt conveying process, the figure-eight arrangement of the gathering plates 614 gathers and gathers the easily flowing lubricating grease on both sides of the upper surface of the steel belt towards the middle of the steel belt, so that the grease is concentrated in the middle area of the steel belt. The vertical motion is converted into rotational motion to realize the adaptive angle adjustment and oil collection of the gathering plate 614.
[0021] In one embodiment of the present invention, a steel belt stabilizing component is provided on one side of the grease gathering component to stabilize the state of the steel belt during the grease gathering process; the steel belt stabilizing component includes a rectangular groove 701 opened on the upper side of one end of the gathering plate 614, and two protrusions 702 integrally extending from one side of the support frame 606. A limiting guide rod 703 is laterally slidably connected at the center of each protrusion 702. A stabilizing roller 704 is rotatably connected to the limiting guide rod 703 near the middle side; an L-shaped frame 705 is connected to the end of the limiting guide rod 703 near the stabilizing roller 704, and a force-bearing shaft 706 is installed at the lower end of the side of the L-shaped frame 705 away from the limiting guide rod 703. The force-bearing shaft 706 is movably inserted into the rectangular groove 701; As the gathering plate 614 deflects at an angle, the rectangular groove 701 on the upper side of one end of the gathering plate 614 rotates and moves synchronously with the gathering plate 614. The groove wall of the rectangular groove 701 presses against the internally movable force shaft 706. The force shaft 706 is driven by the lateral thrust to move the L-shaped frame 705 synchronously. The L-shaped frame 705 pulls the limiting guide rod 703 to slide laterally along the protrusion 702 that extends integrally with the support frame 606. The limiting guide rod 703 drives the stabilizing roller 704 rotatably connected to it to move synchronously. Because the wide steel strip itself has a small deformation fluctuation during processing, the required area for pressing and stabilizing is small. Therefore, the larger the opening at the end of the gathering plate 614, the shorter the lateral movement distance of the stabilizing roller 704. After displacement, the stabilizing roller 704 adheres to the area of the steel strip after grease gathering and compacts and limits it in a small range, suppressing the slight shaking that occurs during the conveying and rolling of the steel strip. Among them, the small displacement of the stabilizing roller 704 locally compacts and stabilizes the wide steel strip. When processing a narrow metal strip, the lateral pressure exerted by the strip on the limiting wheels 604 on both sides disappears. The first spring 602, which has been stretched and deformed, generates a retraction force, pulling the transmission rods 603 on both sides to slide laterally inward along the support rod 601. The transmission rods 603 simultaneously drive the limiting wheels 604 and the drive wedge 605 to move inward and reset. After the drive wedge 605 moves inward, it releases the inclined surface compression constraint on the driven wedge 611. The stretched second spring 609 generates a retraction traction force, pulling the drive plate 610 to move vertically downward and reset. The drive plate 610 drives the driven wedge 611 to move downward and reset simultaneously. In this process, the automatic reset of each component to adapt to the narrow steel strip is achieved by relying on the spring force. As the drive plate 610 moves downward, the drive block 613 inside the limiting groove 612 slides along the reverse curve of the drive groove 608, thereby driving the drive shaft 607 to rotate in the opposite direction. The reverse-rotating drive shaft 607 drives the lower end gathering plate 614 to deflect in the opposite direction to adjust the angle. The two sides of the gathering plates 614 still maintain the figure-eight arrangement. The smaller the width of the steel strip, the larger the opening of the grease gathering port at the front end of the gathering plate 614 and the smaller the opening at the rear end. It can still accurately collect the lubricating grease on both sides of the upper surface of the steel strip into the middle area of the steel strip, which is suitable for the grease distribution requirements of narrow steel strips. Among them, the drive shaft 607 reverses to fine-tune the angle of the gathering plate, which is suitable for the oil collection of narrow steel strips. Simultaneously, the angle of the gathering plate 614 changes in the opposite direction, the rectangular groove 701 shifts synchronously and squeezes the force shaft 706 again. The force shaft 706 pushes the limiting guide rod 703 along the protrusion 702 to slide laterally over a long distance through the L-shaped frame 705, causing the stabilizing roller 704 to shift laterally significantly. Since the deformation fluctuation is large during the processing of narrow steel strip, the area that needs to be pressed and stabilized is larger. After the stabilizing roller 704 moves a long distance, it can fit into the area after the steel strip is gathered and compact and limit it, and perform compaction and limit over a larger range to ensure the smooth conveying of narrow steel strip and the rolling accuracy. Among them, the large-scale sliding of the stabilizing roller 704 expands the range of pressing and stabilizing the narrow steel strip.
[0022] Working principle: When the equipment is powered on and in standby mode, the metal strip of the electric vehicle mudguard to be rolled is first guided and limited by the limiting roller 5 above the oil tank 4. Then, the end of the strip is inserted into the rolling gap between the main rolling wheel 2 and the auxiliary pressure forming wheel 3. At the same time, the strip is inserted laterally into the clamping area between the two sets of limiting wheels 604, so that the upper surface of the strip is in contact with the lower end face of the gathering plate 614, thus completing the material insertion and positioning operation before the strip is processed.
[0023] Start the internal drive mechanism of the bending machine body 1. The drive mechanism drives the output end of the bending machine body 1 to rotate. The rotating output end drives the main rolling wheel 2 and the auxiliary pressure forming wheel 3 to rotate synchronously in opposite directions. The rotating main rolling wheel 2 and the auxiliary pressure forming wheel 3 extrude, bend and roll the metal strip passing between them to complete the basic outline forming of the electric vehicle metal mudguard.
[0024] When processing metal strips with a large width, the two sides of the wide strip push the limiting wheels 604 outward. After being squeezed by the strip, the limiting wheels 604 drive the transmission rod 603 to slide laterally outward along the support rod 601. The sliding transmission rod 603 stretches the first spring 602 sleeved on the outer wall of the support rod 601. At the same time, the drive wedge 605 fixed at the upper end of the transmission rod 603 moves outward synchronously with the transmission rod 603. The outwardly moving drive wedge 605 conforms to and squeezes the driven wedge 611 through its own inclined surface. The driven wedge 611 is driven by the oblique squeezing force to make the drive plate 610 move vertically upward. The drive plate 610 slides upward along the outer wall of the drive shaft 607 through the limiting groove 612 it has opened. At the same time, it pulls the second spring 609 sleeved on the outside of the drive shaft 607 upward to stretch and deform it.
[0025] When the drive plate 610 moves upward, the drive block 613 installed on the inner wall of the limiting groove 612 moves upward along with it. The drive block 613 slides along the drive groove 608, which is in the shape of a spring curve on the outer wall of the drive shaft 607. During the sliding process, the drive shaft 607 is driven to rotate. The lower end of the rotating drive shaft 607 is fixedly connected to the gathering plate 614, which in turn drives the gathering plate 614 to deflect and rotate synchronously. After the two gathering plates 614 deflect synchronously, they form a figure-eight arrangement. The larger end of the figure-eight opening of the gathering plate 614 is opposite to the direction of steel strip conveying. The wider the steel strip, the smaller the opening of the grease gathering port at the front end of the two gathering plates 614 and the larger the opening at the rear end. During the steel strip conveying process, the figure-eight arrangement of the gathering plates 614 gathers and gathers the easily flowing lubricating grease on both sides of the upper surface of the steel strip towards the middle of the steel strip, so that the grease is concentrated in the middle area of the steel strip. During the subsequent rolling process, the grease will be evenly distributed under the pressure of the main rolling wheel 2 and the auxiliary pressure shaping wheel 3.
[0026] As the gathering plate 614 deflects at an angle, the rectangular groove 701 on the upper side of one end of the gathering plate 614 rotates and moves synchronously with the gathering plate 614. The groove wall of the rectangular groove 701 presses against the internally movable force shaft 706. The force shaft 706 is driven by the lateral thrust to move the L-shaped frame 705 synchronously. The L-shaped frame 705 pulls the limiting guide rod 703 to slide laterally along the protrusion 702 that extends integrally with the support frame 606. The limiting guide rod 703 drives the stabilizing roller 704 rotatably connected to it to move synchronously. Because the wide steel strip itself has a small deformation fluctuation during processing and requires a small range of pressing and stabilizing area, the larger the opening at the end of the coiling plate 614, the shorter the lateral movement distance of the stabilizing roller 704. After displacement, the stabilizing roller 704 is in contact with the area after the steel strip grease is coiled to perform small-range compaction and limiting, suppressing the slight shaking that occurs during the conveying and rolling of the steel strip. When processing a metal strip with a small width, the lateral pressing force of the strip on the two limiting wheels 604 disappears, and the first spring 602, which is stretched and deformed, generates a retraction force, pulling the two transmission rods 603 to slide laterally inward along the support rod 601; the transmission rods 603 simultaneously drive the limiting wheels 604 and the drive wedge 605 to move inward and reset; after the drive wedge 605 moves inward, it releases the inclined surface pressing constraint on the driven wedge 611, and the stretched second spring 609 generates a retraction traction force, pulling the drive plate 610 to move vertically downward and reset; the drive plate 610 drives the driven wedge 611 to move downward and reset simultaneously. As the drive plate 610 moves downward, the drive block 613 inside the limiting groove 612 slides along the reverse curve of the drive groove 608, thereby driving the drive shaft 607 to rotate in the opposite direction. The reverse-rotating drive shaft 607 drives the lower end gathering plate 614 to deflect in the opposite direction to adjust the angle. The two sides gathering plates 614 still maintain the figure-eight arrangement. The smaller the width of the steel strip, the larger the opening of the grease gathering port at the front end of the gathering plate 614 and the smaller the opening at the rear end. It can still accurately collect the lubricating grease on both sides of the upper surface of the steel strip into the middle area of the steel strip, which is suitable for the grease distribution requirements of narrow steel strips. Simultaneously, the angle of the gathering plate 614 changes in the opposite direction, the rectangular groove 701 shifts synchronously and squeezes the force shaft 706 again. The force shaft 706 pushes the limiting guide rod 703 along the protrusion 702 to slide laterally over a long distance through the L-shaped frame 705, causing the stabilizing roller 704 to shift laterally significantly. Since the deformation fluctuation is large during the processing of narrow steel strip, the area that needs to be pressed and stabilized is larger. After the stabilizing roller 704 moves a long distance, it can fit into the area after the steel strip is gathered and compact and limit it, thus ensuring the smoothness of the narrow steel strip conveying and the rolling accuracy.
