Description

Technical Field

[0001] This application relates to the field of roller pressing die technology, and in particular to a device and method for preventing roller pressing die from swaying. Background Technology

[0002] Roll forming refers to the process of continuously engaging a metal sheet with a set of complex-curved concave and convex rollers, causing localized bending and stretching deformation to shape the metal sheet into a product with a specific cross-sectional shape. This process has advantages such as continuous processing and minimal thinning during forming. Roll forming mainly consists of two modes: roll-to-roll and roll-to-plate, abbreviated as R2R and R2P, respectively. In both modes, the roller dies are rotating bodies with characteristic surface structures.

[0003] During roll forming experiments, regardless of whether it's a roll-to-roll or roll-to-plate test, the feed roll of the roll forming die is subjected to the squeezing action of the die. When the feed roll installed on the roll forming equipment is a cantilever beam structure, and the length of the feed roll exceeds a certain value, the central axis of the feed roll will inevitably deflect in the opposite direction. Furthermore, the deflection is more pronounced at the end of the roll furthest from the base of the feed roll, which cannot meet the requirement of consistent deformation of different parts of the sheet metal with the same target dimensions.

[0019] This invention provides a device to prevent the roller pressing die from swaying. The cylindrical surfaces of the adjusting members of two sets of adjusting mechanisms abut against the surface of the feed roller of the roller pressing die. The fixing block is fixed in the recess at the upper end of the adjusting plate. The longitudinal telescopic mechanism passes through the lower end of the adjusting plate and the mounting base. The detection mechanism is used to detect the contour of the feed roller parallel to its axis in real time and convert it to obtain its position information, which is the position information of the central axis. The longitudinal telescopic mechanism drives the adjusting plate to move closer to or away from the stop block in real time according to the position information, thereby driving the adjusting member to move longitudinally in real time. In this way, the adjusting member can move away from or closer to the surface of the feed roller in real time according to the sway of the central axis of the feed roller.

[0027] Please refer to Figures 1-3 As shown, this embodiment of the invention provides a device for preventing the swaying of a roll forming die, including a mounting base 1, an adjusting plate 2, a longitudinal telescopic mechanism 3, a detection mechanism, and two sets of adjusting mechanisms 4. The mounting base 1 includes a mounting block 11 and a stop block 12. The lower side of the mounting block 11 is integrally connected to the upper side of the stop block 12, and the lower bottom of the mounting block 11 and the front end face of the stop block 12 form a placement space. The mounting block 11 is fixed on the roll forming equipment, thereby fixing the mounting base 1 on the roll forming equipment. The plate body 21 of the adjusting plate 2 is disposed within the placement space, and a notch is formed at its upper end. The adjusting mechanism 4 includes a fixing block 41 and adjusting members 42. One adjusting member 42 is fixed to the lower end of one fixing block 41, and the two fixing blocks 41 are secured within the notch. The adjusting member 42 can provide a cylindrical surface, and the cylindrical surfaces of the two adjusting members 42 are used to abut against the surface of the feed roller of the roll forming die. Specifically, the cylindrical surfaces of the two adjusting members 42 are used to abut against the bearing at the lower end of the feed roller of the roll forming die. The longitudinal telescopic mechanism 3 passes through the lower ends of the adjusting plate 2 and the mounting base 1. Here, longitudinal refers to... Figure 1 The OZ axis is shown in the direction. The detection mechanism is used to detect the contour of the feed roller in real time and convert it into position information. The longitudinal telescopic mechanism 3 drives the adjustment plate 2 to move closer to or further away from the stop block 12 in real time according to the position information.

[0028] The device for preventing the roller pressing die from swaying provided in this application embodiment has two sets of adjusting mechanisms 4, the cylindrical surfaces of the adjusting members 42 of the adjusting mechanism 4 abutting against the surface of the feed roller of the roller pressing die. The fixing block 41 is fixed in the recess at the upper end of the plate body 21 of the adjusting plate 2. The longitudinal telescopic mechanism 3 passes through the lower end of the adjusting plate 2 and the mounting base 1. The detection mechanism is used to detect the contour of the feed roller parallel to its axis in real time and convert it to obtain its position information, which is the position information of the central axis. The longitudinal telescopic mechanism 3 drives the adjusting plate 2 to move closer to or further away from the stop block 12 in real time according to the position information, thereby driving the adjusting member 42 to move longitudinally in real time. In this way, the adjusting member 42 can move away from or closer to the surface of the feed roller in real time according to the swaying of the central axis of the feed roller. When a significant deflection is detected at the lower end of the feed roller away from its base, the longitudinal telescopic mechanism 3 is immediately controlled to move the adjusting component 42 closer to the surface of the feed roller. This allows for real-time adjustment of the feed roller's central axis. Simultaneously, the adjusting component 42 applies a resisting force to the feed roller, preventing the central axis of the feed roller from deflecting. Consequently, the deformation degree of the blank contacted at the lower end of the roller is consistent with that of the blank contacted at the upper end, thus meeting the requirement for consistent deformation of plates of the same target size at different locations.

[0029] Furthermore, such as Figures 1-3 As shown, the device for preventing the roller pressing die from deflecting also includes a lateral telescopic mechanism 5. Lateral refers to... Figure 1 The OX axis is shown in the diagram. The lateral telescopic mechanism 5 is connected to the fixed blocks 41 and is configured to adjust the position of the two fixed blocks 41 so that the cylindrical surfaces of the two adjusting members 42 abut against the surface of the feed roller of the roll forming die. The lateral telescopic mechanism 5 allows the two fixed blocks 41 to move along the width direction of the notch ( Figure 1 The distance between the two fixed blocks 41 can be adjusted by moving the blocks in the X-axis direction, thereby adjusting the distance between the adjusting members 42 fixed below the two fixed blocks 41, so that the two adjusting members 42 can press against the surface of the feed roller.

[0030] Optionally, the lateral telescopic mechanism 5 includes two lateral telescopic components. One lateral telescopic component passes through one side of the adjusting plate 2 and is mounted on the adjacent fixed block 41. The other lateral telescopic component passes through the other side of the adjusting plate 2 and is mounted on another adjacent fixed block 41. The arrangement of the two lateral telescopic components allows for convenient control of the movement of the two fixed blocks 41 along the width direction of the notch. Of course, the lateral telescopic mechanism 5 can also drive the two fixed blocks 41 to move along the width direction of the notch in real time based on the position information of the feed roller measured in real time by the detection mechanism.

[0031] Optionally, the lateral telescopic mechanism 5 can also pass through one side of the adjustment plate 2, the two fixed blocks 41 and the other side of the adjustment plate 2 in sequence, so that the two fixed blocks 41 can move simultaneously along the width direction of the notch.

[0032] like Figures 1-3 As shown, the lateral telescopic assembly includes a first lead screw 51 and a first driving member. The fixing block 41 has a through first threaded hole along its width, and the adjusting plate 2 has a first through hole on each side. One end of the first lead screw 51 passes through the first through hole and the first threaded hole in sequence, serving as a free end, while the other end passes through the first bearing fixing seat on the outer side of the adjusting plate 2 and is then connected to the first driving member, serving as a fixed end.

[0033] The lateral telescopic component provided in this application embodiment has a simple structure and is easy to implement. When it is necessary for the fixed block 41 to move along the width direction of the notch, the first driving member is activated, and the first driving member drives the first lead screw 51 to rotate, so that the fixed block 41 moves relative to the first lead screw 51, thereby moving the fixed block 41 along the width direction of the notch of the adjusting plate 2.

[0034] Alternatively, the fixed block 41 may have a through hole extending along its width. Inside the fourth through hole is a first nut that mates with the first lead screw 51. One end of the first lead screw 51 passes through the first through hole and the first nut in sequence, serving as a free end, while the other end passes through the first bearing fixing seat on the outer side of the adjusting plate 2 and is then connected to the first driving component, serving as a fixed end.

[0035] Continue to refer to Figures 1-3 As shown, the adjusting member 42 includes a bearing 421 and a bolt 422. The bearing 421 is sleeved on the bolt 422, with its front end fixed to the bottom of the fixing block 41. The outer surfaces of the two bearings 421 abut against the surface of the feed roller of the roll forming die. The adjusting member 42 provided in this embodiment has a simple structure and is easy to implement. The outer surfaces of the two bearings 421 abut against the surface of the feed roller of the roll forming die, providing a resisting force to the feed roller and effectively preventing the feed roller from swerving in the opposite direction. Simultaneously, to ensure that the bearings 421 of the adjusting member 42 can cooperate with the movement of the bearings of the feed roller, both the bearings of the feed roller and the bearings 421 of the adjusting member 42 are configured with fixed inner rings and rotating outer rings. The simultaneous rotation of the outer rings of the lower bearing of the feed roller and the outer rings of the bearings 421 of the adjusting member 42 avoids a rigid collision between the feed roller and the device preventing the roll forming die from swerving.

[0036] Furthermore, such as Figure 3As shown, an annular platform 43 is provided at the position where the bolt 422 is fixed on the bottom surface of the fixing block 41. The inner diameter of the annular platform 43 is less than or equal to the inner diameter of the inner ring of the bearing 421, and the outer diameter is less than or equal to the inner diameter of the outer ring of the bearing 421. Therefore, when the bearing 421 is fitted onto the bolt 422 and the front end of the bolt 422 is fixed to the bottom of the fixing block, the annular platform 43 can cover the end face between the inner diameter of the inner ring and the inner diameter of the outer ring of the bearing 421, and hold and fix the inner ring of the bearing 421. This allows the outer ring of the bearing 421 to rotate relative to the inner ring of the bearing 421, better coordinating with the movement of the feed roller bearing, and thus avoiding a rigid collision between the feed roller and the device for preventing the roller pressing die from swaying.

[0037] like Figures 1-3 As shown, the mounting base 1 also includes a base plate 13 and a front plate 14. The base plate 13 and the front plate 14 are arranged perpendicularly to each other, thus forming an L-shape. The side of the base plate 13 is connected to the bottom of the stop block 12, so that the front plate 14 is parallel to the stop block 12, thereby forming a certain gap between the front plate 14 and the stop block 12, which can limit the adjustment gap of the adjusting plate 2 and prevent the adjusting plate 2 from moving too far when it moves toward the feed roller. The arrangement of the base plate 13 can also provide load-bearing capacity for the adjusting plate 2.

[0038] Continue to refer to Figures 1-3 As shown, the longitudinal telescopic mechanism 3 includes a second lead screw 31 and a second driving member. The stop block 12 has a longitudinal second through hole, the plate body 21 of the adjusting plate 2 has a longitudinal second threaded hole, and the front plate 14 has a longitudinal third through hole. One end of the second lead screw 31 passes sequentially through the second through hole, the second threaded hole, the third through hole, and the second bearing fixing seat in front of the front plate 14. The other end passes through the third bearing fixing seat behind the stop block 12 and then connects to the second driving member. The end of the second lead screw 31 furthest from the second driving member is the supporting end, and the other end is the fixed end. When the adjusting plate 2 needs to move closer to or further away from the stop block 12 under the drive of the longitudinal telescopic mechanism 3, the second driving member is opened. The second driving member drives the second lead screw 31 to rotate, and the adjusting plate 2 moves relative to the second lead screw 31, thereby moving the adjusting plate 2 closer to or further away from the stop block 12 under the drive of the longitudinal telescopic mechanism 3.

[0039] Alternatively, the plate 21 of the adjusting plate 2 may be provided with a longitudinal fifth through hole, and a second nut that mates with the second lead screw 31 may be installed inside the fifth through hole. One end of the second lead screw 31 passes through the second through hole, the second nut, the third through hole and the second bearing fixing seat in front of the front plate 14 in sequence, and the other end passes through the third bearing fixing seat behind the stop block 12 and then connects to the second driving member. The end of the second lead screw 31 away from the second driving member is the supporting end, and the other end is the fixing end.

[0040] Optionally, one end of the second lead screw 31 passes through the second through hole, the second threaded hole, or the second nut in sequence and serves as a free end, while the other end passes through the third bearing fixing seat behind the stop block 12 and is then connected to the second drive component, serving as a fixed end.

[0041] like Figure 2 As shown, the adjustment plate 2 also includes two L-shaped sub-plates 22. The two L-shaped sub-plates 22 are respectively disposed on both sides of the recess. The fixing block 41 is relatively large. The L-shaped sub-plates 22 are arranged such that their side plates can abut against the fixing block 41 and their lower plates can support the fixing block 41, which makes it easy for the fixing block 41 to be fixed to the adjustment plate 2 and prevents it from falling off. At the same time, it facilitates the connection between the fixing block 41 and the transverse telescopic mechanism 5.

[0042] Furthermore, the detection mechanism includes an imaging component and a calculation module, with the imaging component and calculation module electrically connected. The imaging component is configured to take a real-time photograph of the contour of the feed roller and transmit the photograph to the calculation module. The calculation module is configured to calculate the angle between the roller contour line parallel to the roller axis and the horizontal line, which is the position information of the feed roller. The longitudinal telescopic mechanism 3 moves the adjustment plate 2 closer to or further away from the stop block 12 in real time according to this angle.

[0043] Specifically, the imaging component includes an industrial camera, an industrial lens, and an industrial light source. The industrial light source is mounted on the side of mounting base 1, illuminating the location of the feed roller. The industrial lens and camera are then installed and positioned to capture images of the feed roller's location. The computing module utilizes GaoNa vision software.

[0044] In actual operation, the industrial camera, industrial lens, industrial light source, and software are turned on. A photograph is taken of the feed roller in its naturally installed state. The resulting image is opened in the software, and the "Position Correction" tool and the "Line Detection, Angle Measurement" function in the "Geometric Measurement" tool are used. The contour line parallel to the axis of the feed roller is selected as the detection object, and the initial angle value between the detection object and the horizontal line is recorded. The "Position Correction" tool allows the detection object to move with the movement of the feed roller. Therefore, when the feed roller deflects, the position of the detection object changes, and the software interface updates to display the current angle value between the detection object and the horizontal line. The second drive mechanism is activated, causing the adjustment plate 2 to approach the surface of the feed roller under the drive of the longitudinal telescopic mechanism 3 until the current angle value returns to the initial angle value before the roll pressing experiment. The second drive mechanism then stops working.

[0045] Optionally, the detection mechanism can also be a displacement sensor, which is set on the side of the feed roller. When the displacement sensor detects that the feed roller is flexing, it controls the longitudinal telescopic mechanism 3 to drive the adjusting plate 2 to move closer to or away from the stop block 12.

[0046] Of course, the device to prevent the roller pressing die from swaying may also include a controller. The detection mechanism, the longitudinal telescopic mechanism 3 and the transverse telescopic mechanism 5 are all connected to the controller, so that the detection mechanism can transmit the position information of the feed roller to the controller in real time, and the controller can then control the working status of the longitudinal telescopic mechanism 3 and the transverse telescopic mechanism 5 in real time.

[0047] Another embodiment of the present invention provides a method for preventing the deflection of a rolling die, using the above-described device for preventing the deflection of a rolling die, comprising:

[0048] An adjusting member 42 is fixed to the lower end of a fixing block 41, and two fixing blocks 41 are then secured to the recess at the upper end of the adjusting plate 2's body 21. The adjusting plate 2 is placed in the mounting space of the mounting base 1, and a longitudinal telescopic mechanism 3 and a detection mechanism are installed. The detection mechanism detects the contour of the feed roller parallel to its axis in real time and converts it into its position information, which is the position information of the central axis. The longitudinal telescopic mechanism 3 drives the adjusting plate 2 to move closer to or further away from the stop block 12 in real time according to the position information, thereby driving the adjusting member 42 to move longitudinally in real time. Thus, the adjusting member 42 can move closer to or further away from the surface of the feed roller in real time according to the deflection of the central axis of the feed roller. When a significant deflection is detected at the lower end of the feed roller away from its base, the longitudinal telescopic mechanism 3 is immediately controlled to move the adjusting component 42 closer to the surface of the feed roller. This allows for real-time adjustment of the feed roller's central axis. Simultaneously, the adjusting component 42 applies a resisting force to the feed roller, preventing the central axis of the feed roller from deflecting. Consequently, the deformation degree of the blank contacted at the lower end of the roller is consistent with that of the blank contacted at the upper end, thus meeting the requirement for consistent deformation of plates of the same target size at different locations.

[0049] Another embodiment of the present invention provides a specific method for preventing the swaying of a roller pressing die.

[0050] Install the lateral telescopic mechanism 5. Fit the bearing 421 onto the bolt 422 to form an adjusting component 42, and fix the adjusting component 42 to the lower end of the fixing block 41. Then, secure the two fixing blocks 41 into the recess at the upper end of the plate 21 of the adjusting plate 2. Pass one end of the first lead screw 51 sequentially through the first through hole on the side of the adjusting plate 2 and the first threaded hole along the width direction of the fixing block 41, so that the first lead screw 51 and the first threaded hole of the fixing block 41 are connected by threads. Then, pass the other end of the first lead screw 51 through the first bearing fixing seat, install the first bearing fixing seat on the outer side of the adjusting plate 2, and connect the first lead screw 51, which has passed through the first bearing fixing seat, to the first driving component.

[0051] Install the longitudinal telescopic mechanism 3. Place the adjusting plate 2 in the placement space of the mounting base 1. Pass one end of the second lead screw 31 sequentially through the second through hole of the stop block 12, the second threaded hole of the plate body 21 of the adjusting plate 2, the third through hole of the front plate 14, and the second bearing fixing seat in front of the front plate 14, so that the second lead screw 31 is threadedly connected to the second threaded hole of the adjusting plate 2. After passing the other end of the second lead screw 31 through the third bearing fixing seat, install the third bearing fixing seat behind the stop block 12, and then connect the second lead screw 31 that has passed through the third bearing fixing seat to the second driving component.

[0052] Install the testing mechanism. Install an industrial light source on the side of mounting base 1 to illuminate the location of the feed roller. Install an industrial lens and camera to take pictures of the feed roller's location. Install GaoNa vision software on the computer.

[0053] When the first and second driving components are activated, the first driving component drives the first lead screw 51 to rotate, and the second driving component drives the second lead screw 31 to rotate, thereby controlling the fixed block 41 along the width direction of the notch at the upper end of the adjusting plate 21. Figure 1 The adjustment plate 2 moves along the length of the base plate 13 of the mounting base 1 (in the X-axis direction) and the adjustment plate 2 moves along the length of the base plate 13 of the mounting base 1 (in the X-axis direction). Figure 1 The adjustment plate 2 moves along the Z-axis, causing the bearings 421 on the two adjusting members 42 to be tangent to the bearing at the lower end of the feed roller. When the bearing at the lower end of the feed roller rotates, the bearings 421 on the two adjusting members 42 can rotate simultaneously. The first driving member is held in place, and the second driving member is opened, causing the adjusting plate 2 to approach the stop block 12 under the drive of the longitudinal telescopic mechanism 3.

[0054] Turn on the industrial camera, industrial lens, industrial light source, and software. Take a picture of the feed roller in its natural installation state, open the image in the software, and use the "Position Correction" tool and the "Line Detection and Angle Measurement" function in the "Geometric Measurement" tool to select the contour line of the feed roller parallel to its axis as the detection object, and record the initial angle value between the detection object and the horizontal line.

[0055] Conduct a roll pressing test. Since the "position correction" tool allows the object to move along with the feed roller, when the feed roller deflects, the position of the object changes, and the software interface updates to display the angle between the object and the horizontal line. Activate the second drive mechanism, causing the adjustment plate 2 to move closer to the surface of the feed roller under the action of the longitudinal telescopic mechanism 3, until the current angle value returns to the initial angle value before the roll pressing test. Then, the second drive mechanism stops working.
