[0002] Existing cold bending forming of metal sheets mainly involves gradually rolling and cold bending the material strip through several sets of rollers.

[0025] In summary, the beneficial effects of the present invention are:

[0026] The present invention replaces multiple sets of roller pressing wheels in traditional processing methods with a set of cold bending wheels with adjustable width, solving the problem that traditional technology needs to be equipped with roller pressing wheel groups of different specifications when processing plates of different sizes, which is time-consuming and has poor versatility. The width of the cold bending wheel and the distance between the auxiliary wheel and the cold bending channel are adjusted according to the forming size requirements of the plate, so that cold bending forming of material strips of various specifications can be achieved without frequent replacement of the roller pressing wheel group, so that the material strips can better fit the predetermined shape requirements during the cold bending forming process. Compared with traditional methods, the present invention can reduce plate forming defects caused by incomplete matching of the roller pressing wheel group specifications, such as inaccurate bending angles, uneven edges, etc., thereby improving the quality stability and consistency of the product.

[0027] In addition, the present invention sets the punching angle mechanism and the breaking mechanism to slide on an inclined slide, and the control device makes their sliding speed consistent with the feeding speed of the feeding mechanism, so that the material strip does not need to stop to wait for the processing of the punching mechanism during the entire processing process, so that the entire processing process can be carried out continuously, greatly shortening the processing cycle of a single product; since there is no need to frequently stop and start the material strip, the entire production process is more stable, the fluctuation of the production rhythm is smaller, and the connection between the various processes is smoother. The continuous processing method avoids the deformation caused by inertial force, and also reduces the wear and scratches and other damages of the material strip during the stopping and starting process, thereby improving the dimensional accuracy and shape accuracy of the product.

DETAILED DESCRIPTION

[0035] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments given here are only used to illustrate and explain the present invention and cannot be used to limit the present invention.

[0036] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also have other implementations and variations thereof. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figures 1 to 6 As shown, the present invention provides an automated equipment for cold-bending the radiator side panels, comprising a frame 1 and a control device. A feeding mechanism 2, a cold-bending mechanism 3, a leveling mechanism 4, and a punching mechanism 5, which are electrically connected to the control device, are sequentially provided on the top of the frame 1.

[0038] The feeding mechanism 2 includes a guide wheel and a guide channel for driving the material belt 6 to move forward. The left and right sides of the guide channel are provided with horizontal limit blocks with adjustable spacing, and the upper and lower sides are provided with height-adjustable straightening wheels. The horizontal limit blocks and the straightening wheels are electrically connected to the control device.

[0039] The guide wheel can be flexibly set at the output end or input end of the guide channel. The specific position selection needs to be comprehensively considered based on the actual feeding process and equipment layout; the static friction between the guide wheel and the material belt 6 accurately drives the material belt 6 to move forward smoothly and continuously along the predetermined path, thereby ensuring the stability and accuracy of the material during the conveying process, providing strong guarantee for subsequent processing.

[0040] A roll-forming mechanism 3 is provided with a roll-forming channel 31 connected to the guide channel. A plurality of height-adjustable auxiliary wheels 33 are provided on the upper surface of the roll-forming mechanism 3. The auxiliary wheels 33 are rollably mounted on the roll-forming mechanism 3 via connecting rods 35. The auxiliary wheels 33 are tangential to the outer surface of the upper surface of the roll-forming channel 31. A pair of roll-forming wheels 32 with adjustable spacing are provided on the left and right sides of the roll-forming channel 31. Each roll-forming wheel 32 is rollably mounted on a telescopic rod 36. The side of the telescopic rod 36 away from the roll-forming wheel 32 is slidably mounted on an inclined slide 34 correspondingly provided on the inner wall of the roll-forming mechanism 3. The roll-forming wheels 32 and the telescopic rod 36 are both electrically connected to the control device.

[0041] The cold bending channel 31 not only guides the material strip 6 in its forward movement but also provides uniform support during its movement to complete the cold bending operation. The material strip 6 gradually bends under the action of the cold bending wheel 32. The support force of the cold bending channel 31 ensures that the material strip 6 does not suffer from excessive local deformation or twisting during the bending process. The cold bending channel 31 works in conjunction with the cold bending wheel 32 to ensure the stability of the material strip 6 during the cold bending process and reduce the scrap rate during the production process. The shape and size of the cold bending channel 31 are determined based on the shape and size of the cold-bend product to be produced, providing a stable spatial environment for the cold bending of the material strip 6.

[0042] The auxiliary wheel 33 cooperates with the cold bending channel 31 to provide a stable clamping force for the material strip 6, maintain the smooth forward movement of the material strip 6, avoid problems such as shaking and offset of the material strip 6, and make the deformation of the material strip 6 during the cold bending process more uniform. The distance between the auxiliary wheel 33 and the cold bending channel 31 is adjusted according to the thickness and material properties of the material strip 6, and appropriate constraints are provided according to these properties of the material strip 6, so that the material strips 6 of various materials can maintain a good state during the cold bending process.

[0043] The bending wheels 32 are located on the left and right sides of the bending channel 31. When the control device drives the telescopic rod 36 to slide along the inclined slide 34, the bending wheels 32 will roll along the longitudinal axis of the bending channel 31. Since the outer periphery of the bending wheels 32 contacts the material strip 6, during the rolling process, the bending wheels 32 will apply a certain amount of pressure to the material strip 6, causing the material strip 6 to gradually bend and deform until the bending operation is completed. The width between the bending wheels 32 is adjustable, and the adjustment is based on the forming size of the material strip 6. When it is necessary to process material strips 6 of different widths or produce bending products of different shapes, the control device adjusts the spacing between the bending wheels 32 according to preset parameters, mainly by adjusting the telescopic length of the telescopic rod 36 to adjust the width of the bending wheels 32, that is, the spacing between the bending wheels 32. Therefore, the adjustable width feature makes the bending forming mechanism 3 highly versatile and adaptable to a variety of different specifications of material strips 6. There is no need to replace a special bending wheel 32 for each size of material strip 6, which reduces production costs and the time cost of equipment replacement. When producing cold-bending products of different shapes, the spacing between the cold-bending wheels 32 can be flexibly adjusted to accurately control the bending degree of the material strip 6, thereby improving product quality.

[0044] The telescopic rod 36 slides in the inclined slide 34 in a predetermined direction. The inclined slide 34 provides it with accurate guidance. By cooperating with the inclined slide 34, the movement trajectory of the cold bending wheel 32 can be accurately controlled, thereby achieving precise control of the cold bending forming of the material strip 6.

[0045] The leveling mechanism 4 includes a plurality of height-adjustable upper straightening rollers 41 and lower straightening rollers 42 rotatably mounted on the frame 1. The upper straightening rollers 41 and the lower straightening rollers 42 are arranged alternately and are electrically connected to the control device. An upper straightening roller 41 is located above two adjacent lower straightening rollers 42. A leveling channel is formed between the upper straightening rollers 41 and the lower straightening rollers 42 for the feed belt 6 to pass through.

[0046] A plurality of rollers are arranged in sequence to form a leveling channel. The material strip 6 undergoes multiple leveling operations of the upper and lower rollers in the process of passing through the leveling channel. The distance between the adjacent lower straightening roller 42 and the upper straightening roller 41 is relatively short. The material strip 6 will be leveled once on the upper and lower surfaces within a relatively short distance. This gradual leveling method can more finely adjust the flatness of the material strip 6. Compared with a single leveling operation, it can more thoroughly eliminate the unevenness of the material strip 6 and improve the accuracy of leveling. The upper straightening roller 41 and the lower straightening roller 42 are height-adjustable, so that the leveling mechanism 4 can adapt to material strips 6 of different thicknesses. In a production line that produces material strips 6 of various specifications, there is no need to replace the leveling mechanism 4. Only the roller height needs to be adjusted to meet the leveling requirements of material strips 6 of different thicknesses.

[0047] The punching mechanism 5 is provided with a punching mechanism 51 for punching the bevel of the cold-bent formed part of the material strip 6 and a cutting mechanism 52 for punching and cutting the material strip 6 in sequence along the conveying direction of the material strip 6. The punching mechanism 51 and the cutting mechanism 52 are both slidably set on the slide rail on the frame 1 through a slider 53. The slider 53 is electrically connected to the control device. The sliding speed of the punching mechanism 51 and the cutting mechanism 52 on the slide rail along the conveying direction of the material strip 6 is consistent with the feeding speed of the feeding mechanism 2.

[0048] In traditional technology, the material strip 6 often needs to stop at the punching mechanism 5 and wait for the punching operation to be completed before continuing to move forward. The frequent stopping and starting of the material strip 6 will generate inertial force, causing the material strip 6 to deform unnecessary during the punching process, resulting in unstable production rhythm, affecting the arrangement of subsequent processes, poor punching accuracy, and serious equipment wear. The punching angle mechanism 51 and the breaking mechanism 52 of the present invention both slide on the slide rail, and the sliding speed is consistent with the feeding speed of the feeding mechanism 2, so that the material strip 6 does not need to stop and wait for the punching mechanism 5 to be processed during the entire processing process, so that the entire processing process can be carried out continuously, greatly shortening the processing cycle of a single product; since there is no need to frequently stop and start the material strip 6, the entire production process is more stable, the fluctuation of the production rhythm is small, and the connection between the various processes is smoother. The continuous processing method avoids the deformation caused by inertial force, and also reduces the wear and scratches of the material strip 6 during the stopping and starting process, thereby improving the dimensional accuracy and shape accuracy of the product.

[0049] As a preferred embodiment of the present invention, both the input end and the output end of the horizontal limit block are provided with guide grooves, and the angle of the guide grooves is 30° to 60°.

[0050] The guide groove can guide the material belt 6 to enter the horizontal limit block smoothly, preventing the material belt 6 from getting stuck or deviating during entry. When the material belt 6 is transmitted from the upstream equipment, the guide groove at the input end can help the material belt 6 accurately align with the entrance of the horizontal limit block, allowing the material belt 6 to smoothly enter the limit block, reducing friction and wear of the material belt 6 during the entry process; the guide groove at the output end can guide the material belt 6 to leave the horizontal limit block smoothly, ensuring that the material belt 6 can continue to be transported in the predetermined direction after leaving the limit block, avoiding the material belt 6 getting stuck or deviating from the predetermined path during exit.

[0051] As a preferred embodiment of the present invention, the horizontal limit block is composed of several groups of limit wheels, which are tangent to the outside of the guide channel. There are several groups of straightening wheels, starting with the straightening wheel group close to the input end of the feeding mechanism 2 and ending with the straightening wheel group close to the output end of the feeding mechanism 2. The distance between the two straightening wheels in each group decreases successively.

[0052] Since the spacing between the two straightening wheels in each group decreases in sequence, a progressive straightening process is formed from the input end to the output end of the feeding mechanism 2. When the material strip 6 enters the straightening wheel group, the larger spacing at the beginning can adapt to the initial bending state of the material strip 6, avoiding damage to the material strip 6 caused by excessive squeezing, making the contact between the material strip 6 and the straightening wheel relatively gentle, and reducing the impact force of the material strip 6 on the straightening wheel; as the material strip 6 advances, the straightening wheel group with gradually decreasing spacing can gradually increase the straightening force on the material strip 6, effectively eliminating the bending deformation of the material strip 6 and improving the straightening effect. Secondly, the change in the force between the material strip 6 and the straightening wheel is also stable, which helps to protect the straightening wheel and reduce the wear of the straightening wheel. The setting of the straightening wheel spacing decreasing in sequence can adapt to material strips 6 with various degrees of curvature. If the curvature of the material strip 6 is large, it can be initially straightened in the straightening wheel group with a larger spacing at the beginning. For material strips 6 with a smaller curvature, the entire straightening process can also play a role in fine adjustment. There is no need to frequently adjust the parameters of the straightening equipment for the material strips 6 with different degrees of curvature, thereby improving the versatility and production efficiency of the equipment.

[0053] As a preferred embodiment of the present invention, the cold-bending channel 31 includes several rollers and a conveyor belt. The conveyor belt is formed by hingedly connecting several steel sheets. The rollers are arranged at equal intervals in the conveyor belt and are installed in the cold-bending forming mechanism 3 through a transmission shaft. The rollers are electrically connected to the control device.

[0054] The control device drives the transmission shaft to rotate, which in turn drives the rollers to drive the conveyor belt to move. The rollers are arranged at equal intervals in the conveyor belt to help apply uniform force to the material belt 6, so that the material belt 6 is deformed evenly during the cold bending forming process. The rotation speed of the rollers is adjusted according to the movement of the material belt 6 and the cold bending requirements to ensure that appropriate support force and friction force are applied to the conveyor belt.

[0055] As a preferred embodiment of the present invention, the rotation axis of the cold bending wheel 32 is inclined at an angle α relative to the plane of the cold bending channel 31, the outer periphery of the cold bending wheel 32 is an arc-shaped interface, and the cold bending wheel 32 is electrically connected to the control device.

[0056] The control device adjusts the inclination angle α of the rotation axis of the cold bending wheel 32 relative to the plane of the cold bending channel 31, which can change the contact position between the material strip 6 and the outer circular arc interface of the cold bending wheel 32. The change in the inclination angle α of the rotation axis of the cold bending wheel 32 will cause the position and posture of the cold bending wheel 32 in the cold bending channel 31 to change, thereby changing the geometric relationship between the contact between the material strip 6 and the cold bending wheel 32. Specifically, when the inclination angle α increases, the contact point between the outer circular arc interface of the cold bending wheel 32 and the material strip 6 will move to one side of the cold bending wheel 32; conversely, when the inclination angle α decreases, the contact point will move to the other side. This change can be precisely adjusted by the control device to achieve precise control of the position of the material strip 6 in the cold bending channel 31. If the contact point moves too much to one side, the force on the material strip 6 on the cold bending wheel 32 will be uneven and the force eccentricity will be too large, resulting in excessive local deformation, excessive stretching or compression of the material, and even cracks or wrinkles, affecting the mechanical properties and surface quality of the material.

[0057] The contact position between the material strip 6 and the arc-shaped interface is preferably within the range of 20%S on both sides of the center line of the arc-shaped interface, where S is the arc length of the arc-shaped interface. When the contact position between the material strip 6 and the arc-shaped interface is within the range of 20%S on both sides of the center line, it can ensure that the force on the cold bending wheel 32 of the material strip 6 is more uniform, and the contact point of the material strip 6 on the cold bending wheel 32 is relatively stable, thereby reducing local stress concentration, avoiding excessive deformation or damage of the material, and reducing forming errors caused by excessive changes in the contact position.

[0058] As a preferred embodiment of the present invention, the longitudinal axis of the inclined slide 34 is inclined at an angle θ relative to the longitudinal axis of the cold-bent channel 31, and the angle θ satisfies the following relationship:

[0059]

[0060] Wherein, h is the cold bending height of the radiator side plate, and L is the length of the inclined slide 34.

[0061] The angle θ determines the rolling path of the cold bending wheel 32 relative to the cold bending channel 31. Controlling the angle θ within a reasonable range can ensure that the cold bending wheel 32 bends and folds the material strip 6 evenly and sequentially as the material strip 6 moves forward on the cold bending channel 31.

[0062] As a preferred embodiment of the present invention, the width b1 of the upper straightening roller 41 is greater than the width b2 of the radiator side plate, and the width b3 of the lower straightening roller 42 is less than the width b2 of the radiator side plate minus twice the thickness t of the strip 6, satisfying the following relationship:

[0063]

[0064]

[0065] The width b1 of the upper straightening roller 41 is greater than the width b2 of the radiator side plate, completely covering the radiator side plate area and the surrounding part of the material strip 6. When the material strip 6 has edge bending or local deformation, the wider upper straightening roller 41 can straighten the side plate and the surrounding area as a whole, avoiding the situation where only the middle part of the side plate is straightened while the edge part is ignored, thereby improving the comprehensiveness and effect of the straightening; the width b3 of the lower straightening roller 42 is less than the width b2 of the radiator side plate minus twice the thickness t of the material strip 6. The narrower design of the lower straightening roller 42 can prevent excessive extrusion of the edge of the material strip 6 (especially the edge part of the radiator side plate), avoid excessive deformation or wrinkling of the material strip 6 at the edge part of the side plate, and protect the shape integrity of the edge of the material strip 6 and the radiator side plate.

[0066] As a preferred embodiment of the present invention, the input end of the feeding mechanism 2 is provided with a reeling mechanism 7, and the reeling mechanism 7 is provided with a Hall sensor for detecting the number of unreeling turns of the material strip 6; the output end of the punching mechanism 5 is provided with a discharging mechanism for receiving the processed radiator side panels.

[0067] As a preferred embodiment of the present invention, the punch angle mechanism 51 includes a first machine base, which is provided with a first clamping device and a side punching device in sequence along the conveying direction of the material strip 6. The first clamping device includes two first clamping structures for clamping the material strip 6 and a first clamping drive device for driving the two first clamping structures to lift and move horizontally together. The side punching device includes a side punch and a side punch drive device for driving the side punch to move horizontally. The side punch is used to punch and bevel the cold-bend formed part of the material strip 6. The first clamping drive device and the side punch drive device are both electrically connected to the control device.

[0068] The two first clamping structures are lifted and lowered and moved horizontally together under the action of the first clamping drive device. When the material strip 6 is conveyed to the appropriate position, the first clamping drive device drives the two first clamping structures to clamp the material strip 6 and fix the material strip 6, thereby preventing the material strip 6 from being displaced during the subsequent side punching operation, thereby ensuring the accuracy of the side punching. The side punch drive device drives the side punch to perform bevel punching at a specific position of the material strip 6 with appropriate force and speed according to the instructions of the control device.

[0069] The punching mechanism 52 includes a second machine base, which is provided with a second clamping device and a punching device in sequence along the conveying direction of the material strip 6. The second clamping device includes two second clamping structures for clamping the material strip 6 and a second clamping drive device for driving the two second clamping structures to lift and move horizontally together. The punching device includes a punching head and a punching head drive device for driving the punching head to move vertically. The punching head is used to punch and cut the material strip 6. The second clamping drive device and the punching head drive device are both electrically connected to the control device.

[0070] The two second clamping structures are driven by the second clamping drive device to rise and fall and move horizontally together. When the material strip 6 reaches the corresponding position of the punching mechanism 52, the second clamping structure clamps the material strip 6 to provide stable fixation of the material strip 6 for subsequent punching operations. The punching head moves vertically under the drive of the punching head drive device. Its task is to punch and cut the material strip 6. After the material strip 6 is clamped by the second clamping device, the punching head drive device drives the punching head to accurately punch and cut the material strip 6 according to the instructions of the control device.

[0071] The first base and the second base are slidably arranged on the slide rails via the slider 53 .

[0072] The first machine base and the second machine base are slidably arranged on the slide rail through the slider 53, so that the punching angle mechanism 51 and the breaking mechanism 52 can be adjusted on the slide rail, which is convenient for adjusting the position of the punching angle mechanism 51 and the breaking mechanism 52 relative to the material strip 6 according to different production needs. It has strong adaptability to the processing of material strips 6 of different specifications or different process flows, thereby improving the flexibility and adaptability of the equipment.

[0073] The working principle of the radiator side panel cold bending forming automatic equipment of the present invention is as follows: the material strip 6 is unwound by the unwinding mechanism 7, and the Hall sensor detects the number of revolutions of the rotating end of the servo motor in the unwinding mechanism 7 to correspond to the number of revolutions of the material strip 6 unwound. The unwound material strip 6 is transmitted to the feeding mechanism 2, and the static friction force generated between the guide wheel and the material strip 6 drives the material strip 6 to move forward smoothly and continuously on the guide channel according to the predetermined path. The spacing between the limiting wheels on the left and right sides of the guide channel is adjusted according to the width of the material strip 6, and the height of the straightening wheels on the upper and lower sides of the guide channel is adjusted according to the thickness of the material strip 6. The material strip 6 is gradually straightened by several groups of straightening wheel groups, and the straightening force on the material strip 6 is gradually increased to effectively eliminate the bending deformation of the material strip 6; the material strip 6 that has completed the straightening process enters the cold bending channel 31 in the cold bending forming mechanism 3, and is moved by multiple auxiliary wheels 33 cooperates with the cold bending channel 31 to provide a stable clamping force for the material strip 6, keeping the material strip 6 moving forward smoothly. When the material strip 6 moves forward in the channel, the control device drives the telescopic rod 36 to slide along the inclined slide 34, thereby driving the cold bending wheel 32 to roll along the longitudinal axis of the cold bending channel 31. The outer periphery of the cold bending wheel 32 always contacts the material strip 6. During the rolling process, the cold bending wheel 32 will exert a certain pressure on the material strip 6, causing the material strip 6 to gradually bend and deform until the cold bending operation is completed; the longitudinal axis of the inclined slide 34 is inclined at an angle θ relative to the longitudinal axis of the cold bending channel 31, and the angle θ determines the rolling path of the cold bending wheel 32 relative to the cold bending channel 31. The angle θ is controlled within a reasonable range to ensure that the material strip 6 is evenly and sequentially cold bent and folded during its advancement on the cold bending channel 31. After the cold bending operation, the material strip 6 enters the leveling mechanism 4, and the non-cold-bent part of the material strip 6 is leveled by multiple upper and lower rollers. The punching mechanism 5 performs the processes of beveling, punching, and cutting on the material strip 6 in sequence, and finally completes the processing of the radiator side plate. The punching mechanism 5 slides on the slide rail, and the sliding speed is consistent with the feeding speed of the feeding mechanism 2, so that the material strip 6 does not need to stop and wait for the processing of the punching mechanism 5 during the entire processing process. The entire processing process is carried out continuously, and the dimensional accuracy and shape accuracy of the product are good.
