Description

Technical Field

[0001] This utility model relates to the field of metal component processing equipment technology, and in particular to a metal component bending correction device. Background Technology

[0002] Metal components are widely used as basic structural and functional units in fields such as machinery manufacturing, construction engineering, and metal product manufacturing. However, during production, transportation, or use, these metal components often bend and deform due to improper stress. This deformation not only affects the aesthetics of the components but also seriously affects their assembly accuracy and structural strength, leading to a decline in the quality of the entire product or project. Therefore, effectively correcting bent and deformed metal components to restore them to a straight state is an essential step in the production and processing process.

[0003] Currently, there are some devices for straightening metal components. These devices typically clamp the two ends or multiple points of the component and then apply a reverse force to the bent or deformed parts, causing the component to undergo plastic deformation and thus restore its straightness. However, such devices in the prior art still have obvious shortcomings in practical applications. On the one hand, the clamping structure design of many straightening devices is relatively simple and the adjustable range is limited. When it is necessary to process metal components of different thicknesses or widths, it is often difficult to achieve effective and firm clamping, resulting in poor applicability. Manufacturers may need to equip themselves with multiple models of equipment to meet different processing needs, which increases costs and floor space.

[0004] On the other hand, for longer metal components, the shortcomings of existing correction devices are more prominent. During the correction process, due to the large distance between the support points of the components, when the correction mechanism applies a large correction force to the bent part, this force will be transmitted along the component. This can easily cause other areas outside the corrected part to undergo new bending or torsional deformation due to the lack of effective support. This secondary deformation not only fails to solve the original problem, but also introduces new defects, making the correction work more complicated and seriously affecting the final correction accuracy and product qualification rate.

[0005] Therefore, this utility model proposes a bending correction device for metal components to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the metal component bending correction device, such as poor clamping adaptability, difficulty in handling components of different specifications, and easy occurrence of secondary deformation when correcting long components, this utility model aims to provide a metal component bending correction device with improved structure that can effectively solve the above problems.

[0007] This utility model provides a bending correction device for metal components, including: an operating table, a turntable, a first clamping unit, a second clamping unit, a mounting plate, a correction component, and a clamping mechanism.

[0008] The mounting plate is fixed to the operating table, the calibration assembly is mounted on the mounting plate, and includes a pneumatic rod for driving the turntable to rotate. The first clamping unit includes a fixed plate and a clamping plate that can move relative to the fixed plate. The second clamping unit is mounted on the turntable and includes a fixed plate and a clamping plate that can move relative to the fixed plate. The clamping mechanism drives the clamping plate and the clamping plate to move respectively, and the linear displacement of the clamping plate and the clamping plate is achieved by the rotation of the screw.

[0009] Furthermore, the operating table, mounting plate and calibration components, turntable and second clamping unit, as well as the clamping mechanism and clamping plate are combined through the aforementioned specific connection methods and positional relationships to jointly constitute the core functional platform of the device.

[0010] Preferably, the calibration assembly further includes a calibration plate and a limiting plate. One end of the pneumatic rod pushes the calibration plate, which in turn drives the turntable to rotate. The limiting plate is used to limit the displacement endpoint of the calibration plate.

[0011] Preferably, the clamping mechanism further includes a fixed seat, a locking block, and a recessed block. The screw is threadedly connected to the fixed seat, and the rotation of the screw drives the clamping plate one or the clamping plate two to move through the cooperation of the locking block and the recessed block.

[0012] Preferably, the clamping mechanism further includes a guide rod, which passes through the fixed seat and is connected to the clamping plate one or the clamping plate two, for providing guidance for the clamping plate one or the clamping plate two during movement.

[0013] Preferably, both the fixing plate and the clamping plate are provided with detachable extension mechanisms on their outer sides, which are used to extend the effective force-bearing area of ​​the first clamping unit.

[0014] Preferably, wedge blocks are fixed on both the fixing plate and the clamping plate, and the extension mechanism includes an extension plate with a notch that mates with the wedge blocks. Installation is achieved through the sliding engagement of the notch with the wedge blocks.

[0015] Preferably, the extension mechanism further includes a reinforcing plate inserted into the extension plate, and a rotating shaft, a rotating block, a stop block, and a limiting block for locking the reinforcing plate.

[0016] Preferably, the rotating block passes through the reinforcing plate and engages with the rotating shaft.

It achieves the technical effect of being able to conveniently clamp and position metal components of different specifications, with strong applicability.

[0018] 2. This utility model, by setting up a correction component driven by a pneumatic rod and limited by a limiting plate, uses the extension of the pneumatic rod to drive the turntable to rotate to achieve automatic correction, which solves the problems of traditional correction methods that rely on manual labor, are inefficient, and have difficulty in guaranteeing correction accuracy. It achieves the technical effect of high automation of the correction process, simple operation, and accurate correction angle, thus ensuring the processing quality.

[0019] 3. This utility model, by setting up a quick-release extension mechanism, can extend the effective force-bearing area of ​​the clamping component on the metal component, solving the problem that when correcting a long component, the support distance is too far and other parts of the component will undergo large deformation.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 5 This utility model provides a metal component bending correction device, which aims to solve the problem that existing metal component correction devices have poor adaptability and are prone to secondary deformation when correcting long components.

[0024] like Figure 1 and Figure 3 As shown, the metal component bending correction device includes an operating table 1, which serves as the mounting base for the entire device. A first clamping unit mounted on the operating table 1 includes a fixed plate 2 and a clamping plate 3 that can move relative to the fixed plate 2. A turntable 4 is rotatably mounted on the operating table 1. A second clamping unit mounted on the turntable 4 includes a fixed plate 606 and a clamping plate 607 that can move relative to the fixed plate 606. A mounting plate 5 is fixed on the operating table 1. A correction component 608 is mounted on the mounting plate 5. A clamping mechanism 6 is used to drive the clamping plate 3 and the clamping plate 607 to move.

[0025] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structural cooperation and connection relationship between the correction component 608 and the clamping mechanism 6.

[0026] Please refer to the following carefully. Figure 2 and Figure 3 The structure will be described in detail below: The calibration assembly 608 includes a calibration plate 6081, a limiting plate 6082, and a pneumatic rod 6083 as a power source. The pneumatic rod 6083 and the limiting plate 6082 are both fixedly connected to the mounting plate 5. The calibration plate 6081 is movably disposed between the pneumatic rod 6083 and the turntable 4. During operation, the extended end of the pneumatic rod 6083 abuts against and pushes the calibration plate 6081, which in turn abuts against and pushes the side edge of the turntable 4 to make it rotate. When the calibration plate 6081 moves to contact the limiting plate 6082, the rotation of the turntable 4 is terminated. Through this structure driven by the pneumatic rod 6083 and limited by the limiting plate 6082, the accuracy and consistency of the calibration action are ensured.

[0027] Meanwhile, the clamping mechanism 6 for clamping metal components includes a fixed base 601, a screw 602, a locking block 603, a recess 604, and a guide rod 605. The fixed base 601 is fixedly connected to the operating table 1 and the turntable 4 respectively. The screw 602 is threadedly connected to the fixed base 601. The recess 604 is fixedly connected to the back of the clamping plate 3 or the clamping plate 2 607. One end of the locking block 603 is accommodated in the annular groove at the end of the screw 602, and the other end is rotatably connected to the recess 604. One end of the guide rod 605 is fixedly connected to the clamping plate 3 or the clamping plate 2 607, and the other end slides through the fixed base 601. This screw-locking block-recess transmission structure efficiently converts the rotational motion of the screw 602 into the linear motion of the clamping plate, while the guide rod 605 ensures the high stability and anti-displacement capability of the clamping plate during movement.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to increase the stress-bearing area when straightening long metal components to prevent additional deformation, please refer to... Figure 1 , Figure 4 and Figure 5 Both the fixed plate 2 and the clamping plate 3 are detachably equipped with extension mechanisms 7 on their outer sides. The extension mechanism 7 includes an extension plate 702, a reinforcing plate 703, and locking components such as a rotating shaft 704, a rotating block 705, a stop block 706, and a limiting block 707. Wedge blocks 701 are fixed to both the fixed plate 2 and the clamping plate 3. The extension plate 702 has a notch that mates with the wedge blocks 701, allowing the extension plate 702 to slide against the wedge blocks 701 through this notch. The reinforcing plate 703... The rotating shaft 704 is fixedly connected to the fixed plate 2 or the clamping plate 3 at the slots at the top of the two extension plates 702. Multiple sets of limiting blocks 707 are evenly distributed along the circumference of the rotating shaft 704. The rotating block 705 passes through the through hole at the top of the reinforcing plate 703. The bottom of the rotating block 705 is fixedly connected to the stop block 706. By rotating the rotating block 705, the stop block 706 can selectively engage or disengage with different limiting blocks 707, thereby firmly locking or quickly disassembling the extension mechanism 7.

[0029] Working principle: The clamping mechanism 6 clamps metal components of different specifications. The correction component 608 on the mounting plate 5 applies force for the correction work. Initially, the pneumatic rod 6083 is retracted, and the turntable 4 can rotate. The distance between the first fixed plate 2 and the first clamping plate 3, and between the second fixed plate 606 and the second clamping plate 607, is sufficient to accommodate the metal component. When it is necessary to correct a bent metal component, the metal component is placed between the first fixed plate 2 and the first clamping plate 3 along the front side of the first fixed plate 2. Simultaneously, the turntable 4 is rotated so that the bent position of the metal is in contact with the front side of the second fixed plate 606. The left fixed seat 601 is fixed to the top of the operating table 1, and the right fixed seat 601 is fixed to the top of the turntable 4. The screws 602 on the front side of the first clamping plate 3 and the second clamping plate 607 are rotated respectively. The screws 602 are threadedly connected to the fixed seats 601. According to the principle of threaded transmission, the two screws... When rod 602 generates axial displacement, the locking block 603 rotates within the recess 604, causing the recess 604 to move back and forth, thereby causing clamping plate 3 and clamping plate 2 607 to move back and forth to adapt to metal components of different specifications. At this time, guide rod 605 slides within fixed seat 601 to prevent the movement paths of clamping plate 3 and clamping plate 2 607 from deviating. When clamping plate 3 and clamping plate 2 607 move backward to press against the surface of the metal component, the clamping and positioning work is completed. Then, pneumatic rod 6083 extends. During this process, its right end pushes the correction plate 6081. The correction plate 6081 drives the turntable 4 and the bent part of the metal component clamped between fixed plate 2 606 and clamping plate 2 607 to rotate until the correction plate 6081 is close to the limiting plate 6082. At this time, fixed plate 2 606 and fixed plate 2 are in the same straight line, and clamping plate 3 and clamping plate 2 607 are parallel, thus completing the correction work. In addition, for longer metal components, to avoid the problem of large deformation in other parts of the component due to pressure during the straightening process caused by a large distance between the two sets of support structures, extension mechanisms 7 are provided on the outside of both the fixing plate 2 and the clamping plate 3 to extend the stress area of ​​the metal component. During installation, the notches of the two extension plates 702 are aligned with the wedge blocks 701 and slid down. There are multiple limit blocks 707 on the rotating shaft 704 fixed on the fixing plate 2 and the clamping plate 3. The two stops 706 at the bottom of the rotating block 705 are connected to the two limit blocks 707. The positioning blocks 707 are connected, and then the bottom of the reinforcing plate 703 is inserted into the slots at the top of the two extension plates 702. The rotating block 705 passes through the through hole at the top of the reinforcing plate 703. Then the rotating block 705 is rotated 90 degrees clockwise. At this time, the two stop blocks 706 are connected to the other two limiting blocks 707, and the bottom of the rotating block 705 is connected to the top of the reinforcing plate 703, thereby fixing the reinforcing plate 703 and the extension plate 702 in the current position, forming an integral part with the clamping component, and respectively extending the effective force-bearing area of ​​the fixing plate 12 and the clamping plate 13.
