Deformation correction system for heat treatment of metal strip profiles

Abstract

The present invention is applicable to the field of deformation correction technology, and provides a deformation correction system for heat treatment of metal strip profiles, including a main body component, a correction component installed in the middle of the main body component, and an adjustment component arranged at both ends of the main body component. The device solves the problem that the existing deformation correction device usually corrects the complete strip profile through a stress correction machine, but if there are equidistant holes on the side wall of the profile, it can only be corrected repeatedly manually, which is inefficient and cumbersome. In addition, the existing device cannot correct deformation and distortion at the same time, and needs to be transferred and used separately to utilize the distortion correction mechanism, which is insufficient in functionality. The device locates and corrects the holes through the hole expansion component to avoid the holes being unable to recover. After the distortion is recovered, the first oil cylinder drives the connecting seat to make the bottom edge of the profile extend between the first rollers, and the second roller fits the side wall of the profile and is at the height of the hole. The profile is driven by the rollers to move back and forth between the correction components for correction, thereby improving the functionality of the device.

Description

Technical Field

[0001] The present invention relates to the field of deformation correction technology, and more specifically, to a deformation correction system for heat treatment of metal strip profiles. Background Art

[0002] When metal strips are heat treated, they are prone to deformation due to uneven stress distribution inside the material and inconsistent thermal expansion and contraction rates at different parts. This deformation is usually caused by the thermal stress generated inside the material exceeding the yield strength of the material during the heating and cooling process, resulting in plastic deformation of the material. In order to control and reduce this deformation, after the metal strips are heat treated, they are corrected by a deformation correction device.

[0003] At present, in the existing deformation correction devices, the profile is usually corrected directly through a stress corrector. However, this method has certain limitations, and it can only work for complete strip profiles. If there are holes set at equal distances on the side wall of the strip profile, it cannot be corrected directly through a stress corrector. In this case, it is often necessary to rely on manual repeated correction. This manual correction method is not only time-consuming and labor-intensive, but also greatly reduces the efficiency of correction, making the entire correction process extremely cumbersome and inefficient.

[0004] Furthermore, when the existing deformation correction device corrects the profile, since the profile will not only bend but also twist, the existing device cannot perform deformation correction and twist correction at the same time. The profile needs to be moved separately and corrected using the twist correction mechanism, which greatly reduces the functionality of the existing device. Summary of the invention

[0016] The present invention is further configured as follows: a positioning cylinder is installed on one side of the fixed plate, the output end of the positioning cylinder passes through the side wall of the fixed plate and is connected to the movable plate, a guide rod is installed on the side wall of the fixed plate, the outer side wall of the guide rod is slidably connected to a plurality of sliders, a limiting column is connected to the side wall of each slider, a plurality of sliding grooves are opened on the side wall of the movable plate, the plurality of sliding grooves are inclined in sequence from the middle of the movable plate to the edge, the plurality of limiting columns are arranged corresponding to the plurality of sliding grooves, and the limiting columns are slidably connected to the inside of the corresponding sliding grooves, the plurality of L-shaped rods are arranged corresponding to the plurality of sliders, and the L-shaped rods are connected to the side walls of the corresponding sliders.

[0021] By adopting the above technical solution, during the distortion of the profile, the hole is positioned by means of the hole expanding assembly, that is, the arc plate of the hole expanding assembly is extended into the hole. When the profile is relatively straight, the hole expanding assembly corrects the hole of the profile at the same time, and avoids the situation where the hole cannot be restored. Before the hole expanding assembly is extended into the hole, the two arc plates are close to each other, and the combined diameter of the two arc plates is smaller than the hole, thereby facilitating the extension into the deformed hole. After the arc plate is extended into the hole, the two arc plates separate from each other to open the hole, thereby achieving the purpose of correcting the hole.

[0022] A method for using a deformation correction system for heat treatment of metal strip profiles, using the deformation correction system for heat treatment of metal strip profiles as described above, the method comprises the following steps:

[0023] S1. The staff places the profile to be corrected on the top of one of the rollers, and uses the roller to drive the profile until the profile moves to the top of the two rollers, and then uses the adjustment component to adjust the position of the clamping component.

[0024] S2. Then, the transfer electric seat is used to slide on the top of the corresponding adjustment component to adjust the positions of the two groups of clamping components corresponding to the adjustment component. Driven by the transfer electric seat, the third rollers on the two groups of clamping components are attached to the side walls of the profile. Then, the third oil cylinder is used to push the ends of the two articulated rods to move. The other ends of the two articulated rods push the clamping table to slide on the fourth guide rail, thereby adjusting the distance between the two third rollers on the same group of clamping components. The two third rollers cooperate to clamp the profile and correct the distortion of the profile.

[0025] S3. During the process of correcting the profile using the clamping assembly, the clamping assembly first maintains the clamping state of the profile, and the profile recovers from the twisted state to the straight state. Then the positioning assembly drives the reaming assembly to extend into the hole on the side wall of the profile. When the profile is twisted and corrected, the positioning assembly is used to correct the hole on the side wall of the profile.

[0026] S4. After the distortion and hole correction of the profile are completed, the positioning component and the hole expansion component are moved away from the profile, and then the profile is clamped by the correction component and the bending correction is performed in the straight line direction.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] (1) By setting an adjustment component, the second oil cylinder is used to drive the square rod and the adjustment seat to slide on the top of the corresponding second guide rail, thereby adjusting the position of the square rod, the third guide rail and the corresponding clamping component. The adjustment component and the clamping component cooperate to achieve the purpose of compatible clamping and correction of profiles of different lengths.

[0029] (2) By setting up a clamping assembly, the transfer electric seat is used to slide on the top of the corresponding adjustment assembly, thereby adjusting the position of the two groups of clamping assemblies corresponding to the adjustment assembly. Driven by the transfer electric seat, the third rollers on the two groups of clamping assemblies are attached to the side walls of the profile. Then, the third oil cylinder is used to push the ends of the two hinged rods to move, and the other ends of the two hinged rods push the clamping table to slide on the fourth guide rail, thereby adjusting the distance between the two third rollers on the same group of clamping assemblies. The two third rollers cooperate to clamp the profile and correct the distortion of the profile. In the correction process, the third rollers open the side walls of the profile and the upper and lower layers, thereby preliminarily adjusting the distance and horizontality of the upper and lower layers of the profile, and the side walls are squeezed to restore the distortion of the profile.

[0030] (3) After the distortion of the profile is restored, there is no need to move the profile. The first cylinder is used to drive the corresponding connecting seat to slide on the top of the corresponding first guide rail. The two connecting seats are close to each other, and the bottom edge of the profile extends between the two vertically opposite first rollers. The second roller fits the side wall of the profile, and the height of the second roller is at the height position of the hole. The profile is driven by the second roller and the first roller to move back and forth between the correction components. During the movement, the profile is gradually corrected, which greatly improves the functionality of the device.

[0031] (4) During the distortion of the profile, the hole is positioned by using the hole expansion assembly, that is, the arc plate of the hole expansion assembly is extended into the hole. When the profile is relatively straight, the hole expansion assembly corrects the hole of the profile at the same time and avoids the situation where the hole cannot be restored.

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0052] See also Figure 1-11 , the present invention provides the following technical solutions:

[0053] Embodiment 1, a deformation correction system for heat treatment of metal strip profiles, includes a main component 1, the main component 1 is used to transport and displace the metal strip profiles to facilitate subsequent deformation correction operations, and the specific structure of the main component 1 is as follows:

[0054] See also Figure 1 and Figure 2 The main component 1 includes two support plates 11, and a plurality of conveying rollers 7 are transmission-connected between the two support plates 11, and the plurality of conveying rollers 7 are respectively located on both sides of the correction component 2, and two rollers 14 are symmetrically rotationally connected between the two support plates 11. The two support plates 11 serve as the main support, and the plurality of conveying rollers 7 are installed between the two support plates 11, and rollers 14 are arranged at both ends of the plurality of conveying rollers 7. Therefore, when the metal strip profile is placed on the main component 1, the rollers 14 are first used for support, and the rollers 14 provide driving force for conveying the profile, so that the profile is sent to the top of the conveying roller 7 and the top of another roller 14 to wait for correction.

[0055] See also Figure 1 and Figure 2In this embodiment, the main component 1 also includes two driving motors 12 installed on the side walls of one of the support plates 11. The two driving motors 12 are arranged corresponding to the two rollers 14, and a transmission mechanism 13 is connected between the output end of the driving motor 12 and the end of the corresponding roller 14. The transmission mechanism 13 consists of a driving wheel, a driven wheel and a synchronous belt. The output end of the driving motor 12 is connected to the driving wheel, and the end of the corresponding roller 14 is connected to the driven wheel. When the driving motor 12 drives the driving wheel to rotate, the driving wheel transmits the driving force to the synchronous belt, and the synchronous belt transfers the transmission force to the driven wheel. The driven wheel drives the corresponding roller 14 to rotate, thereby achieving the purpose of conveying the profile.

[0056] See also Figure 1 A correction component 2 is installed on the top of the support plate 11. After the metal strip profile is heat-treated, its internal stress and the thermal expansion and contraction of the material are inconsistent, which causes bending and deformation. The correction component 2 is used to correct the curvature of the profile and restore the shape of the metal strip profile to facilitate subsequent use. The specific structure of the correction component 2 is as follows:

[0057] See also Figure 1 , Fig.10 and Fig.11 The correction component 2 includes a base 21 installed in the middle of the bottom surface of the two support plates 11, a first guide rail 23 is installed on the top of the base 21, and two connecting seats 24 are slidably connected to the top of the first guide rail 23. The two connecting seats 24 are connected to the first oil cylinder 22 on one side that repels each other. The shell of the first oil cylinder 22 is connected to the top surface of the base 21. The first oil cylinder 22 is used to drive the corresponding connecting seat 24 to slide on the top of the corresponding first guide rail 23. Two baffles 25 are installed on the top of each connecting seat 24. A mounting frame 26 is rotatably connected to the top of the connecting seat 24 and located between the two baffles 25. Four first oil cylinders 22 are symmetrically and vertically rotatably connected at the four corners of the side wall of the mounting frame 26. A roller 28, wherein a second roller 29 is horizontally rotatably connected between two horizontally opposite first rollers 28, wherein a first spring rod 27 is hinged on the side wall of one baffle 25, and the telescopic end of the first spring rod 27 is hinged to the side of the mounting frame 26 away from the first roller 28, and the two connecting seats 24 are close to each other, and the bottom edge of the profile extends between the two vertically opposite first rollers 28, and the second roller 29 is in contact with the side wall of the profile, and the height of the second roller 29 is at the height position of the hole, and the profile is driven by the second roller 29 and the first roller 28 to reciprocate between the correction components 2, and the profile is gradually corrected during the movement.

[0058] In the second embodiment, when the existing deformation correction device corrects the profile, since the profile will not only bend but also twist, the existing device cannot perform deformation correction and twist correction at the same time. The profile needs to be moved separately and corrected using the twist correction mechanism, which greatly reduces the correction efficiency.

[0059] See also Figure 1 To this end, adjustment components 3 are installed at both ends of the main component 1, and two groups of clamping components 4 are slidably connected to the top of each group of adjustment components 3. The adjustment components 3 are used to adjust the positions of the corresponding clamping components 4, and then adjust the spacing between the corresponding clamping components 4 on the two groups of adjustment components 3. The adjustment components 3 and the clamping components 4 cooperate to achieve the purpose of compatible clamping and correction of profiles of different lengths.

[0060] See also Figure 3 , the specific structure of the adjustment component 3 is as follows:

[0061] The two groups of adjustment components 3 include two adjustment frames 31, which are respectively installed on one side opposite to the two support plates 11, and the tops of the two adjustment frames 31 are respectively installed with second guide rails 32, and the tops of the second guide rails 32 are slidably connected with adjustment seats 33, and the tops of the two adjustment seats 33 are horizontally connected with square rods 34, and the tops of the square rods 34 are connected with third guide rails 35, and the clamping assembly 4 is slidably connected to the tops of the corresponding third guide rails 35. The two groups of adjustment components 3 also include two second oil cylinders 36, which are respectively installed on one side opposite to the two support plates 11, and the piston rods of the two second oil cylinders 36 are connected to the tops of the corresponding square rods 34, and the second oil cylinders 36 drive the square rods 34 and the adjustment seats 33 to slide on the tops of the corresponding second guide rails 32, thereby adjusting the positions of the square rods 34, the third guide rails 35 and the corresponding clamping assembly 4, and the adjustment assembly 3 cooperates with the clamping assembly 4 to achieve the purpose of clamping and correcting profiles of different lengths.

[0062] See also Figure 4 The specific structure of the clamping assembly 4 is as follows:

[0063] Each group of clamping components 4 includes a transfer electric seat 41 slidably connected to the top of the corresponding adjustment component 3 and an L-shaped plate 43 installed on the top of the corresponding transfer electric seat 41. A third oil cylinder 42 is horizontally installed on one side of the L-shaped plate 43. The piston rod of the third oil cylinder 42 penetrates the L-shaped plate 43 and is hinged to two hinged rods 44. A limit plate 45 is installed on the side of the L-shaped plate 43 away from the third oil cylinder 42. A fourth guide rail 46 is vertically installed on the side of the limit plate 45 close to the L-shaped plate 43. Two clamping platforms 47 are slidably connected to the fourth guide rail 46. One end of the two hinged rods 44 away from the third oil cylinder 42 is hinged to the two clamping platforms 47 respectively. One side of the clamping table 47 is rotatably connected to the third roller 48, and the transfer electric seat 41 is composed of a driving motor, a wheel body and a sliding seat, that is, the driving motor drives the wheel body to move, so that the wheel body moves on the third guide rail 35, thereby adjusting the position of the sliding seat, and when the sliding seat moves, it drives the L-shaped plate 43 and the various components installed on the L-shaped plate 43 to move synchronously, thereby adjusting the position of the third roller 48, and the third oil cylinder 42 is used to drive one end of the two articulated rods 44 to move, and the other end of the articulated rod 44 pushes the corresponding clamping table 47 to slide on the fourth guide rail 46, thereby adjusting the distance between the two third rollers 48 on the same group of clamping components 4.

[0064] Specifically, the transfer electric seat 41 is used to slide on the top of the corresponding adjustment component 3, and then the position of the two groups of clamping components 4 corresponding to this adjustment component 3 is adjusted. Driven by the transfer electric seat 41, the third rollers 48 on the two groups of clamping components 4 are attached to the side walls of the profile, and then the third oil cylinder 42 is used to push the ends of the two hinged rods 44 to move, and the other ends of the two hinged rods 44 push the clamping platform 47 to slide on the fourth guide rail 46, so as to adjust the distance between the two third rollers 48 on the same group of clamping components 4. The two third rollers 48 cooperate to clamp the profile and correct the distortion of the profile. In the correction process, the third rollers 48 open the side walls and the upper and lower layer positions of the profile, and then preliminarily adjust the distance and horizontality of the upper and lower layer plates of the profile, and the side walls are squeezed to restore the distortion of the profile, and the profile is restored from a twisted state to a straight state.

[0065] In the third embodiment, since there are holes on the side wall of the profile, when the profile is twisted or bent, the shape of the holes will be deformed, and some holes will be excessively twisted or bent, which will cause edge folding.

[0066] See also Figure 1To this end, a positioning component 5 is installed on the top of the main component 1 and above the correction component 2, and a hole expansion component 6 is installed at the bottom of the positioning component 5. The positioning component 5 is used to adjust the position of the hole expansion component 6. When the profile is deformed and corrected, the hole expansion component 6 is used to position the hole, that is, the hole expansion component 6 extends into the hole. When the profile is corrected, the hole expansion component 6 corrects the hole of the profile at the same time and avoids the situation where the hole cannot be restored. The specific structure of the positioning component 5 is as follows:

[0067] See also Figure 5 and Figure 6 The positioning assembly 5 includes a gantry 51 installed on the top of the two support plates 11 and an electric slide rail 52 installed on the bottom of the gantry 51.

The number of reaming assemblies 6 is the same as the number of L-shaped rods 55. A set of reaming assemblies 6 is installed on the bottom side wall of each L-shaped rod 55.

[0068] See also Figure 5 , Figure 6 , Figure 8 and Fig. 9 A positioning cylinder 54 is installed on one side of the fixed plate 53, and the output end of the positioning cylinder 54 passes through the side wall of the fixed plate 53 and is connected to a movable plate 591. A guide rod 58 is installed on the side wall of the fixed plate 53, and a plurality of sliders 59 are slidably connected to the outer wall of the guide rod 58. A limiting column 593 is connected to the side wall of each slider 59. A plurality of slide grooves 592 are provided on the side wall of the movable plate 591, and the plurality of slide grooves 592 are arranged in sequence from the middle of the movable plate 591 to the edge. A plurality of limiting columns 593 are arranged corresponding to the plurality of slide grooves 592, and the limiting columns 593 are slidably connected to the inside of the corresponding slide grooves 592. A plurality of L-shaped rods 55 are arranged corresponding to the plurality of sliders 59, and the L-shaped rods 55 are connected to the side walls of the corresponding sliders 59. In the process of correcting the profile by using the clamping assembly 4, the clamping assembly 4 first maintains the clamping state of the profile, and the profile is restored from the twisted state to the straight state, and then the gantry 51 drives the electric slide rail 52 and the Multiple components linked by the electric slide rail 52 descend until the height of the reaming assembly 6 is consistent with the hole height of the profile, and then the positioning cylinder 54 pushes the movable plate 591 to slide on the side wall of the fixed plate 53, and the slide groove 592 on the side wall of the movable plate 591 squeezes the corresponding limit column 593. The limit column 593 is displaced by the force and drives the slider 59 to slide on the guide rod 58. Multiple L-shaped rods 55 are equidistantly separated to adjust the spacing. During the adjustment process, the L-shaped rods 55 drive the corresponding multiple groups of reaming assemblies 6 to synchronously displace and adjust the position.

When the electric slide rail 52 drives the fixed plate 53 to move in the direction of the profile, the suction cup 56 first contacts the profile and reversely squeezes the second spring rod 57 During the contraction of the second spring rod 57, the two arc plates 613 in a group of hole-supporting mechanisms 61 are inserted into the same hole. When the two arc plates 613 of all hole-supporting mechanisms 61 are inserted into the corresponding holes, the clamping cylinder 611 is started and drives the corresponding two clamping blocks 612 to separate from each other. The two arc plates 613 are separated synchronously and support and correct the holes. After completing one correction, the positioning component 5 and the hole expansion component 6 are away from the profile, and the profile continues to be transported a distance of a fixed number of hole spacings, and then the holes of the profile are corrected through the cooperation of the positioning component 5 and the hole expansion component 6.

[0071] And before the expansion assembly 6 is extended into the hole, the two arc plates 613 are close to each other, and the combined diameter of the two arc plates 613 is smaller than the hole, so that it is convenient to extend into the deformed hole. After the arc plates 613 are extended into the hole, the two arc plates 613 separate from each other to open the hole, thereby achieving the purpose of correcting the hole.

[0072] Embodiment 4, a method for using a deformation correction system for heat treatment of metal strip profiles, using the deformation correction system for heat treatment of metal strip profiles as described above, the method comprises the following steps:

[0073] S1. The staff places the profile to be corrected on the top of one of the rollers 14 and uses the rollers 14 to drive the profile until the profile moves to the top of the two rollers 14, and then uses the adjustment component 3 to adjust the position of the clamping component 4.

[0074] More specific steps are:

[0075] S11. The staff places the profile that needs to be corrected on the top of one of the rollers 14, and uses the roller 14 to drive the profile to be conveyed until the profile moves to the top of the two rollers 14. Then, the second oil cylinder 36 is used to drive the square rod 34 and the adjustment seat 33 to slide on the top of the corresponding second guide rail 32, thereby adjusting the position of the square rod 34, the third guide rail 35 and the corresponding clamping assembly 4.

[0076] S2. Then, the transfer electric seat 41 is used to slide on the top of the corresponding adjustment component 3, thereby adjusting the positions of the two groups of clamping components 4 corresponding to this adjustment component 3. Driven by the transfer electric seat 41, the third rollers 48 on the two groups of clamping components 4 are attached to the side walls of the profile. Then, the third oil cylinder 42 is used to push the ends of the two articulated rods 44 to move. The other ends of the two articulated rods 44 push the clamping platform 47 to slide on the fourth guide rail 46, thereby adjusting the distance between the two third rollers 48 on the same group of clamping components 4. The two third rollers 48 cooperate to clamp the profile and correct the distortion of the profile.

[0077] S3. During the process of correcting the profile using the clamping assembly 4, the clamping assembly 4 first maintains the clamping state of the profile, and the profile recovers from the twisted state to the straight state. Then the positioning assembly 5 drives the reaming assembly 6 to extend into the hole on the side wall of the profile. When the profile is twisted and corrected, the positioning assembly 5 is used to correct the hole on the side wall of the profile.

[0078] More specific steps are:

[0079] S31. During the correction process of the profile using the clamping assembly 4, the clamping assembly 4 first maintains the clamping state of the profile, and the profile recovers from a twisted state to a straight state. Then the gantry 51 drives the electric slide rail 52 and multiple components linked to the electric slide rail 52 to descend until the hole expansion assembly 6 is consistent with the hole height of the profile. Then the positioning cylinder 54 pushes the movable plate 591 to slide on the side wall of the fixed plate 53. The slide groove 592 on the side wall of the movable plate 591 squeezes the corresponding limit column 593. The limit column 593 is displaced by force and drives the slider 59 to slide on the guide rod 58. Multiple L-shaped rods 55 are equidistantly separated to adjust the spacing.

[0080] S32, then the electric slide rail 52 drives the fixed plate 53 to move in the direction of the profile. First, the suction cup 56 contacts the profile and squeezes the second spring rod 57 in the opposite direction. During the contraction of the second spring rod 57, the two arc plates 613 in a group of hole-supporting mechanisms 61 are inserted into the same hole. When the two arc plates 613 of all hole-supporting mechanisms 61 are inserted into the corresponding holes, the clamping cylinder 611 is started and drives the corresponding two clamping blocks 612 to separate from each other. The two arc plates 613 are separated synchronously and support and correct the holes.

[0081] S33. After completing one correction, the positioning assembly 5 and the hole expanding assembly 6 are moved away from the profile, and the profile continues to be transported a distance of a fixed number of hole spacings, and then the holes of the profile continue to be corrected through S31 and S32.

[0082] S4. When the distortion and hole correction of the profile are completed, the positioning component 5 and the hole expansion component 6 are moved away from the profile, and then the profile is clamped by the correction component 2, and the bending correction is performed in the straight line direction.

[0083] S41. When the distortion and hole correction of the profile are completed, the positioning assembly 5 and the hole expanding assembly 6 are away from the profile, and then the first oil cylinder 22 drives the connecting seat 24 to slide on the first guide rail 23, and the two connecting seats 24 approach each other. The bottom edge of the profile extends between two vertically opposite first rollers 28, and the second roller 29 fits with the side wall of the profile, and the height of the second roller 29 is at the height position of the hole.

[0084] S42, by driving the second roller 29 and the first roller 28, the profile is reciprocated between the correction components 2, and the profile is gradually corrected during the movement.

[0085] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
