Description

Technical Field

[0001] This utility model relates to the technical field of steel plate processing equipment, and in particular to an automatic welding deformation correction device. Background Technology

[0002] Welding is an essential connection process in the manufacture of metal structures. However, due to the localized high-temperature heating and subsequent rapid cooling during welding, uneven thermal expansion and contraction occur inside the steel plate, resulting in significant residual thermal stress. This residual stress often causes various forms of deformation in the steel plate, such as bow-shaped deformation, wavy deformation, or torsional deformation, which seriously affects the subsequent assembly accuracy and structural strength. Therefore, it is necessary to perform correction treatment on the welded steel plate.

[0003] Currently, steel plate straightening typically employs multi-roller leveling machines. These machines use staggered straightening rollers to repeatedly bend the steel plate, eliminating internal stress and achieving a flat surface. While this roller straightening principle is theoretically sound, existing equipment exhibits significant structural deficiencies in practical applications, particularly when straightening long or large welded steel plates. When the steel plate enters the straightening roller system, its long overhang and the intense compression and vibration during the straightening process easily cause lateral swaying or shifting at both ends.

[0004] This lateral swaying not only causes the steel plate to deviate from the centerline during feeding, significantly reducing the edge correction effect and lowering the flatness accuracy of the finished product, but also, severe swaying can cause the steel plate edge to collide with the machine frame, resulting in equipment damage. Most existing auxiliary guiding devices use fixed baffles, which, while limiting displacement, have high frictional resistance, easily scratching the steel plate surface, and cannot automatically adjust for centering based on the steel plate width, making it difficult to meet the requirements of automated, high-precision correction.

[0005] Therefore, this utility model proposes an automatic welding deformation correction device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an automatic welding deformation correction device, which aims to improve the problem that some existing automatic welding deformation correction devices tend to wobble at both ends of long steel plates when correcting them, resulting in a decrease in correction accuracy.

[0007] This utility model provides an automatic welding deformation correction device, comprising: a base, a fixed frame fixedly connected to the top of the base, an active roller and a driven roller rotatably connected inside the fixed frame, and a lower correction roller rotatably connected inside a groove opened on the top of the base.

[0008] Furthermore, stabilizing mechanisms are fixedly connected to both side walls of the base. The base, the fixing frame, and the stabilizing mechanisms are combined by fixing them to the side walls to provide auxiliary support for the edges of the steel plate.

[0009] The stabilizing mechanism has a bidirectional synchronous clamping structure, which includes a support plate fixedly connected to the side wall of the base, a base plate slidably connected to the top of the support plate, a limiting plate fixedly connected to the top of the base plate, a slider slidably connected between the two limiting plates, a toothed plate fixedly connected to the side wall of each of the two sliders on opposite sides, and a gear rotatably connected to the top of the base plate.

[0010] Two toothed plates are respectively meshed and connected to opposite sides of the gear. The drive end of an electric push rod is fixedly connected to the side wall of the slider, and the electric push rod is fixedly installed on the top of the base plate. Rubber rollers are rotatably connected to the top of both sliders. The electric push rod drives one slider to move, and the transmission between the toothed plates and the gear drives the other slider to move synchronously in the opposite direction, thereby causing the two rubber rollers to quickly center and clamp the steel plate.

[0011] Preferably, the stabilizing mechanism further includes a protective shell fixedly connected to the top of the base plate. The protective shell covers the outside of the gear and is used to shield and protect the rotating gear and the meshing parts to prevent foreign objects from being drawn in.

[0012] Preferably, the stabilizing mechanism further includes an adjustment component, the structural details of which have a sliding adjustment function. It includes a bolt fixedly connected to the bottom of the base plate, and a limiting groove is formed on the top of the support plate. The bolt slides through the limiting groove, thereby allowing the base plate to be adjusted in position relative to the support plate.

[0013] Preferably, the adjusting assembly further includes a nut threaded to the bottom end of the bolt, the top of the nut abutting against the bottom of the support plate, and by tightening the nut, the adjusted base plate is locked onto the support plate by friction.

[0014] Preferably, the base is provided with a cleaning mechanism to solve the problem of debris accumulation. The cleaning mechanism includes a square groove on the top of the base, two square grooves symmetrically distributed on both sides of the recess, and two pipes connecting the square grooves and the recess are formed inside the base to create a connected airflow channel.

[0015] Preferably, the cleaning mechanism further includes a fan fixedly connected inside the square groove. The fan is located at one end of the pipe that connects to the square groove and is used to generate negative pressure airflow to draw debris in the groove into the square groove through the pipe.

[0016] Preferably, the cleaning mechanism further includes an adsorption net installed inside the square groove, the adsorption net being located on the side of the fan away from the duct, for intercepting and collecting debris in the airflow.

[0017] Preferably, the inner walls on both sides of the square groove are provided with slots, and the two sides of the adsorption net are slidably connected to the inside of the two slots. This connection method makes it easy to quickly pull out the adsorption net for cleaning or replacement.

[0018] Preferably, the cleaning mechanism further includes a cover plate rotatably connected to the top of the base, the cover plate covering the top opening of the square groove to seal the space above the square groove, ensuring the airtightness of the internal flow channel and preventing external dust from falling in.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problem in the prior art that the ends of long steel plates are prone to shaking during the correction process, resulting in a decrease in correction accuracy, by setting a stable mechanism on both sides of the machine base, driven by an electric push rod and using gear and rack meshing transmission to achieve bidirectional synchronous movement, and in conjunction with a rotatable rubber roller. It achieves the technical effect of automatically aligning and clamping both ends of the steel plate synchronously without hindering the longitudinal feed of the steel plate, effectively preventing lateral shaking, and improving correction accuracy.

[0021] 2. This utility model solves the problem in the prior art where oxide scale and debris generated during correction easily accumulate at the lower straightening roller, causing the equipment to jam or be difficult to clean, by setting a pipe inside the machine base to connect the lower roller groove and the side square groove, and combining it with a fan and an adsorption net to form a negative pressure cleaning mechanism. It achieves the technical effect of automatically sucking the debris that falls into the groove to the adsorption net for centralized collection, preventing debris from getting stuck in the roller shaft, and ensuring the long-term stable operation of the equipment.

[0022] 3. This utility model, by setting an adjustment component, utilizes the sliding fit of bolts in the limiting groove of the support plate and the locking fixation of nuts to solve the problem that the fixed auxiliary support structure in the prior art cannot adapt to steel plates of different lengths and specifications. It achieves the technical effect of flexibly adjusting the working position of the stabilizing mechanism according to the actual size of the steel plate to be corrected, ensuring that the rubber roller always accurately abuts the edge of the steel plate, and improving the applicability of the device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] Reference Figures 1 to 4 This utility model provides an automatic welding deformation correction device, which aims to solve the problems in the prior art where the ends of excessively long steel plates are prone to shaking during the correction process, resulting in a decrease in correction accuracy, and the debris generated during correction is easy to accumulate inside the equipment and is difficult to clean.

[0036] like Figure 1 and Figure 4As shown, the machine includes a base 1 and two fixed frames 2 fixedly connected to the top of the base 1. A drive roller 3 and a driven roller 4 are rotatably connected inside the fixed frames 2. The drive roller 3 and the driven roller 4 cooperate to roll-press and correct the upper surface of the steel plate. A groove 8 is provided on the top of the base 1. A lower straightening roller 7 is rotatably connected inside the groove 8. The lower straightening roller 7 is used to press against the bottom of the steel plate, cooperating with the drive roller 3 and the driven roller 4 to eliminate the welding deformation stress of the steel plate.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, stabilizing mechanisms 5 are fixedly connected to both side walls of the base 1. The stabilizing mechanisms 5 are used to clamp and limit the ends of the steel plate during the calibration process, preventing lateral swaying. The stabilizing mechanism 5 includes a support plate 507 fixedly connected to the side wall of the base 1. A base plate 501 is slidably connected to the top of the support plate 507. The base plate 501 serves as the movable base of the stabilizing mechanism 5, supporting subsequent clamping components. Two limiting plates 505 are fixedly connected to the top of the base plate 501. Two sliders 509 are slidably connected between the two limiting plates 505. A toothed plate 503 is fixedly connected to the opposite side wall of each slider 509. A gear 504 is rotatably connected to the top of the base plate 501.

[0038] Two toothed plates 503 are located on opposite sides of the gear 504, and both toothed plates 503 are meshed with the gear 504. Through the meshing transmission between the gear 504 and the two toothed plates 503, the two sliders 509 can achieve synchronous movement towards each other or away from each other, thereby ensuring the centering of the steel plate clamping. The drive end of the electric push rod 502 is fixedly connected to the side wall of the slider 509. The electric push rod 502 is fixedly installed on the top of the base plate 501. The electric push rod 502 serves as a power source to drive the slider 509 to reciprocate along the direction guided by the limiting plate 505 on the base plate 501.

[0039] Both sliders 509 have rubber rollers 508 rotatably connected to their tops. The rubber rollers 508 are vertically positioned to abut against the side edges of the steel plate. Because the rubber rollers 508 are rotatable, they restrict the lateral displacement of the steel plate without hindering its longitudinal corrective feed movement. The stabilizing mechanism 5 also includes a protective shell 506 fixedly connected to the top of the base plate 501. The protective shell 506 covers the gear 504. The protective shell 506 prevents external objects from being drawn into the meshing point between the gear 504 and the gear plate 503, protecting the normal operation of the transmission structure. The protective shell 506 has through holes on both side walls for the gear plate 503 to pass through, ensuring unobstructed movement of the gear plate 503.

[0040] The stabilizing mechanism 5 also includes an adjusting component 510, and the adjusting component 510 forms a specific sliding adjustment and locking relationship with the aforementioned base plate 501 and support plate 507.

[0041] Reference Figure 3 The adjusting assembly 510 includes a bolt 5102 fixedly connected to the bottom of the base plate 501. The bolt 5102 extends vertically downward. Correspondingly, a limiting groove 5103 is formed on the top of the support plate 507. The limiting groove 5103 extends along the length of the support plate 507 and penetrates the upper and lower surfaces of the support plate 507. In the assembled state, the bolt 5102 slides through the limiting groove 5103. Through the sliding engagement of the bolt 5102 and the limiting groove 5103, the base plate 501 can move linearly back and forth on the top of the support plate 507 along the trajectory of the limiting groove 5103. This sliding connection structure ensures that the base plate 501 can drive the top slider 509 and the rubber roller 508 to move closer to or further away from the machine base 1, thereby flexibly adjusting the working position of the stabilizing mechanism 5 according to the actual length of the steel plate to be corrected, ensuring that the rubber roller 508 can always accurately contact the edge of the steel plate.

[0042] The adjusting assembly 510 also includes a nut 5101 threaded to the bottom end of the bolt 5102. The top of the nut 5101 abuts against the bottom of the support plate 507. When it is necessary to fix the position of the base plate 501, tighten the nut 5101 so that the nut 5101 fits tightly against the bottom of the support plate 507. The axial tension between the bolt 5102 and the nut 5101 clamps and fixes the base plate 501 and the support plate 507, preventing the stabilizing mechanism 5 from shifting due to vibration during the steel plate alignment process.

[0043] In a preferred embodiment, a cleaning mechanism 6 is provided on the base 1. The cleaning mechanism 6 includes two square grooves 64 formed on the top of the base 1. The two square grooves 64 are symmetrically distributed on both sides of the recess 8. In order to clean the debris inside the recess 8, two pipes 66 are formed inside the base 1. The pipes 66 connect the square grooves 64 and the recess 8.

[0044] One end of the pipe 66 opens onto the side wall of the groove 8, and the other end opens onto the side wall of the square groove 64. The cleaning mechanism 6 also includes a fan 63 fixedly connected inside the square groove 64. The fan 63 is located at the end of the pipe 66 that connects to the square groove 64. As a negative pressure source, the fan 63 generates suction during operation, drawing air and suspended debris from inside the groove 8 into the square groove 64 through the pipe 66, thus preventing debris from accumulating around the lower straightening roller 7 and affecting equipment operation. The cleaning mechanism 6 also includes an adsorption net 62 installed inside the square groove 64. The adsorption net 62 is located on the side of the fan 63 away from the pipe 66, i.e., on the air outlet side of the fan 63 or downstream of the airflow. The adsorption net 62 is used to block and adsorb airborne debris particles, allowing the cleaned air to escape while retaining the debris inside the square groove 64.

[0045] As a further preferred embodiment, slots 65 are provided on the inner walls of both sides of the square groove 64. The two sides of the adsorption net 62 are slidably connected to the inside of the two slots 65. When the adsorption net 62 accumulates too much debris and needs to be cleaned, it can be removed from the slots 65 by sliding, and then reinserted after cleaning, which is simple to operate.

[0046] In another preferred embodiment, the cleaning mechanism 6 also includes a cover plate 61 rotatably connected to the top of the base 1. The cover plate 61 covers the top opening of the square groove 64. In normal operation or shutdown, the cover plate 61 is in a closed state, which can seal and protect the inside of the square groove 64; when it is necessary to clean the adsorption net 62, the cover plate 61 can be flipped open to expose the internal space of the square groove 64 for operation.

[0047] The working principle of this utility model is as follows:

[0048] Before using the device, adjust the position of the stabilizing mechanism 5 on the side of the base 1 according to the length of the steel plate to be corrected. Loosen the nut 5101, move the base plate 501 so that the bottom bolt 5102 slides inside the limiting groove 5103, and drive the entire stabilizing mechanism 5 to move along the support plate 507 to a suitable position. Then, tighten the nut 5101 again to fix the base plate 501.

[0049] Connect the device to an external power source and start it. Place the steel plate that has undergone welding deformation between the two fixed frames 2 on top of the machine base 1. The drive roller 3 inside the fixed frame 2 rotates under drive, and works in conjunction with the driven roller 4 and the lower straightening roller 7 to continuously roll the steel plate. The steel plate is subjected to repeated bending as it passes through the roller system, thereby eliminating internal stress and achieving flatness correction.

[0050] During the calibration process, to prevent the ends of the excessively long steel plate from wobbling, the electric push rod 502 is activated. The electric push rod 502 drives a slider 509 connected to it to move along the direction of the limiting plate 505 on the base plate 501. The slider 509 drives the toothed plate 503 on the side wall to move, thereby driving the gear 504 on the base plate 501 to rotate. The rotation of the gear 504 further drives the toothed plate 503 on the other side to move in the opposite direction, thus causing the two sliders 509 to move synchronously relative to each other or towards each other under the guidance of the limiting plate 505. This action drives the two rubber rollers 508 at the top to move closer to the edge of the steel plate until the rubber rollers 508 press against both sides of the steel plate. Since the rubber rollers 508 are rotatable, they restrict the lateral sway of the steel plate while allowing the steel plate to feed smoothly in the longitudinal direction, thereby improving calibration accuracy while ensuring calibration efficiency.

[0051] Simultaneously, to clean up the debris generated during the straightening process, the fan 63 in the cleaning mechanism 6 is activated. The fan 63 generates negative pressure, which draws the oxide scale and debris that have fallen into the groove 8 into the square groove 64 through the pipe 66. The debris is blocked and adsorbed by the adsorption net 62, preventing it from getting stuck in the straightening roller. After the work is completed, the cover plate 61 is opened, and the adsorption net 62 is pulled out along the slot 65 for cleaning.
