Description

Technical Field

[0001] This utility model belongs to the field of production equipment technology, and specifically relates to a CNC angle steel production equipment. Background Technology

[0002] CNC angle steel production equipment plays a vital role in modern industrial production, widely used in industries such as power transmission towers, communication towers, and steel structure buildings. This type of equipment automates the angle steel processing, covering key steps such as marking (stamping), punching (including round holes and elongated holes), and shearing. For example, the common TAPM1010 series high-speed CNC angle steel production line, controlled by a PLC module and fed by a servo motor, can efficiently and accurately complete angle steel processing, significantly improving production efficiency and ensuring the stability of processing accuracy.

[0003] However, traditional CNC angle steel production equipment has many drawbacks. Its limitations are particularly evident in the angle steel flange straightening process. Previous straightening methods often fail to meet the diverse straightening needs of angle steel flanges of different specifications. For example, some traditional straightening equipment cannot flexibly adjust the spacing between straightening components, making it difficult to achieve precise straightening when dealing with angle steel flanges of different thicknesses, seriously affecting product quality. Moreover, traditional equipment largely relies on manual operation; manual loading and unloading is not only labor-intensive but also prone to human error. During the angle steel flange straightening process, manually pushing the angle steel point by point for straightening is extremely inefficient and cannot meet the pace of large-scale industrial production. Simultaneously, the structural design of traditional straightening equipment is not reasonable, with poor coordination between components. For instance, the connection method between the straightening roller and the mounting bracket in some straightening equipment results in high resistance during roller rotation, consuming more energy and reducing the overall service life of the equipment. In addition, traditional equipment lacks an effective mechanism for handling debris and other impurities generated during processing. These impurities tend to accumulate in the straightening area, which not only exacerbates equipment wear but may also affect the straightening quality, resulting in defects on the surface of the straightened angle steel flange. Utility Model Content

[0004] In view of this, the present invention provides a CNC angle steel production equipment that solves the technical problems of low correction accuracy and difficulty in adapting to different specifications in the angle steel flange correction process of traditional CNC angle steel production equipment, thereby improving the angle steel flange correction quality and the overall performance of the equipment.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a CNC angle steel production equipment, which includes two sets of straightening rollers, upper and lower, and mounting brackets for mounting the straightening rollers. The upper straightening roller is mounted on the liftable mounting bracket, and the lower straightening roller is mounted on the fixed mounting bracket. The surfaces of the upper and lower straightening rollers are provided with grooves that fit the flanges of the angle steel. The lower straightening roller is connected to a motor via a chain to achieve synchronous rotation. The mounting bracket of the upper straightening roller is connected to an adjusting motor via a screw and nut mechanism.

[0007] The technical advantages of the CNC angle steel production equipment provided by this utility model are as follows: the upper and lower sets of straightening rollers work together, and the upper straightening roller can be raised and lowered to adapt to the straightening needs of angle steel flanges of different specifications; the groove matches the angle steel flange to ensure the fit during straightening and improve the straightening accuracy; the lower straightening roller is driven by a motor to rotate, which can drive the angle steel to feed automatically, reduce manual operation, and improve straightening efficiency; the screw nut mechanism and the setting of the adjusting motor realize precise control of the raising and lowering of the upper straightening roller.

[0008] Based on the above technical solution, the CNC angle steel production equipment of this utility model can be further improved as follows:

[0009] The mounting bracket for the upper straightening roller includes a lifting frame and a mounting base connected to each other. The lifting frame is connected to the lead screw and nut mechanism, and the upper straightening roller is rotatably mounted on the mounting base.

[0010] The lifting frame includes a horizontal connecting plate and a vertical guide plate. The horizontal connecting plate is fixedly connected to the nut of the lead screw and nut mechanism. The vertical guide plate is provided with a guide hole that matches the guide rod. The vertical guide plate is sleeved on the guide rod through the guide hole and slides with the guide rod.

[0011] Furthermore, the lead screw and nut mechanism includes a lead screw and a nut, the lead screw is connected to the output shaft of the adjusting motor, the nut is fixed on the lifting frame, and the lead screw and the nut are threaded together.

[0012] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the screw and nut mechanism has a simple structure and stable transmission, which can convert the rotational motion of the adjusting motor into the linear motion of the lifting frame, thereby achieving precise adjustment of the height of the upper straightening roller; the nut is fixed on the lifting frame, ensuring that the lifting frame will not deviate during the lifting process, thus improving the stability and straightening accuracy of the straightening mechanism.

[0013] Furthermore, the fixed mounting bracket for the lower straightening roller includes a fixed frame and a support base connected to each other, and the lower straightening roller is rotatably mounted on the support base.

[0014] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the structural design of the fixed frame and support base provides a stable installation foundation for the lower straightening roller, ensuring the stability of the lower straightening roller during rotation; the lower straightening roller is rotatably mounted on the support base, reducing rotational resistance, enabling the lower straightening roller to smoothly drive the angle steel to move, and improving straightening efficiency.

[0015] Furthermore, the grooves of the upper straightening roller and the lower straightening roller are both concave shapes that match the shape of the angle steel flange, and the grooves of the upper straightening roller and the lower straightening roller are arranged opposite each other in the vertical direction. The surfaces of the grooves of the upper straightening roller and the lower straightening roller are provided with spiral guide grooves.

[0016] The concave shape includes a groove width adapted to the thickness of the angle steel flange and a groove bottom radius consistent with the outer radius of the angle steel flange. The groove width is greater than or equal to the thickness of the angle steel flange and less than or equal to 1.2 times the thickness of the angle steel flange. The radius of the groove bottom radius is 0.95-1.05 times the outer radius of the angle steel flange.

[0017] Furthermore, the chain surrounds and connects the output shaft sprocket of the motor and the sprocket of the lower straightening roller, and the motor drives the lower straightening roller to rotate through the chain.

[0018] Furthermore, the regulating motor is fixed to the equipment frame via a motor mounting base, and the motor mounting base is connected to the equipment frame by bolts; the motor mounting base includes a base plate and a vertical plate, the base plate is provided with an oblong hole, and the equipment frame is provided with a corresponding threaded hole, the bolts pass through the oblong hole and engage with the threaded hole to achieve a detachable connection.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the detachable bolt connection facilitates the installation, disassembly and maintenance of the motor; the waist-shaped hole design of the motor mounting base allows for adjustment of the motor position within a certain range, facilitating the installation and debugging of the lead screw and nut mechanism and ensuring the accuracy of the upper straightening roller lifting adjustment; the detachable connection method also facilitates the overall transportation and assembly of the equipment.

[0020] Furthermore, both ends of the upper straightening roller are respectively mounted on the mounting bracket of the upper straightening roller via bearings, and both ends of the lower straightening roller are respectively mounted on the mounting bracket of the lower straightening roller via bearings.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by installing the straightening roller with bearings, the frictional resistance between the straightening roller and the mounting bracket can be greatly reduced, allowing the straightening roller to rotate flexibly; at the same time, the bearings can withstand the radial and axial loads generated during the straightening process, ensuring the stability of the straightening roller under high-speed rotation and stress conditions, and extending the service life of the straightening roller and the mounting bracket.

[0022] Furthermore, it also includes a guide rod for guiding the lifting and lowering of the upper straightening roller mounting bracket. One end of the guide rod is fixed to the equipment frame, and the other end passes through the mounting bracket of the upper straightening roller and slides in cooperation with the mounting bracket of the upper straightening roller; the sliding cooperation is a clearance cooperation.

[0023] Furthermore, the upper straightening roller and the lower straightening roller are made of a metal material with a hardness higher than that of angle steel, and the surface of the groove is provided with a wear-resistant coating.

[0024] The metallic material includes any one of chromium-molybdenum alloy steel, tungsten steel, or alloy tool steel, and the wear-resistant coating is any one of tungsten carbide coating, titanium nitride coating, or ceramic coating.

[0025] Compared with existing technologies, the beneficial effects of the CNC angle steel production equipment provided by this utility model are:

[0026] The angle steel flange straightening mechanism of this utility model has many significant advantages. First, the design of upper and lower straightening rollers, and the fact that the upper straightening roller can be precisely adjusted in height via a screw and nut mechanism and an adjusting motor, greatly improves the equipment's adaptability to angle steel flanges of different specifications. Whether the angle steel flange is thin or thick, adjusting the height of the upper straightening roller ensures that the grooves of both rollers fit tightly against the angle steel flange, thus achieving high-precision straightening.

[0027] The groove design on the surface of the straightening roller, which adapts to the flange of the angle steel, is a key factor in improving the straightening quality. This concave shape, which closely matches the shape of the angle steel flange, includes a precisely matched groove width and a groove bottom curvature consistent with the outer radius of the angle steel flange. This ensures that the straightening roller and the angle steel flange can make full and close contact during the straightening process. As a result, the straightening force is evenly distributed on the angle steel flange, effectively avoiding the problem of uneven straightening deformation caused by local stress concentration, significantly improving the straightening quality, and enabling the straightened angle steel flange to better meet the requirements of subsequent production processes.

[0028] The lower straightening roller is driven by a motor via a chain, enabling automatic feeding of the angle steel. This automated design significantly reduces manual operation, lowering the labor intensity of workers and greatly improving production efficiency. Compared to the traditional method of manually pushing angle steel for straightening, this invention enables continuous and efficient straightening operations, greatly shortening the production cycle and providing strong support for enterprises to increase production capacity and reduce production costs.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0036] like Figs. 1-3 The image shows a first embodiment of a CNC angle steel production equipment provided by this utility model. In this embodiment, it includes two sets of straightening rollers, an upper set and a mounting bracket 30 for mounting the straightening rollers. The upper straightening roller 10 is mounted on the liftable mounting bracket 30, and the lower straightening roller 20 is mounted on the fixed mounting bracket 30. The surfaces of the upper straightening roller 10 and the lower straightening roller 20 are provided with grooves 11 that are adapted to the flanges of the angle steel. The lower straightening roller 20 is connected to a motor via a chain to achieve synchronous rotation. The mounting bracket of the upper straightening roller 10 is connected to an adjusting motor via a screw and nut mechanism 40.

[0037] Place the angle steel at the feed end between the upper and lower straightening rollers, start the adjusting motor, and adjust the height of the upper straightening roller through the screw nut mechanism so that the grooves of the upper and lower straightening rollers fit tightly with the flange of the angle steel; start the motor that drives the lower straightening roller to rotate, and the lower straightening roller drives the angle steel forward through friction. During the movement, the upper and lower straightening rollers squeeze and straighten the flange, completing the flange straightening operation of the angle steel.

[0038] In the above technical solution, the mounting bracket 30 of the upper straightening roller 10 includes a lifting frame 31 and a mounting base 32 connected to each other. The lifting frame 31 is connected to the lead screw and nut mechanism 40, and the upper straightening roller 10 is rotatably mounted on the mounting base 32.

[0039] When installing the equipment, first connect and fix the lifting frame to the screw and nut mechanism, then install the mounting base on the lifting frame, and finally install the upper straightening roller on the mounting base through rotating parts such as bearings. During use, the lifting frame is raised and lowered by adjusting the motor to drive the screw and nut mechanism, which in turn drives the mounting base and the upper straightening roller to rise and fall. When straightening angle steel, the upper straightening roller rotates on the mounting base and works with the lower straightening roller to complete the straightening work.

[0040] Furthermore, in the above technical solution, the lead screw and nut mechanism 40 includes a lead screw and a nut. The lead screw is connected to the output shaft of the regulating motor, and the nut is fixed on the lifting frame 31. The lead screw and the nut are threadedly engaged.

[0041] After the regulating motor starts, the output shaft drives the lead screw to rotate. Since the nut is fixed on the lifting frame, the rotational motion of the lead screw is converted into the linear lifting motion of the nut and the lifting frame through the threaded engagement. According to the straightening requirements of the angle steel flange, the height of the upper straightening roller is precisely adjusted by controlling the rotation direction and number of turns of the regulating motor, so that it forms a suitable straightening pressure with the lower straightening roller.

[0042] Furthermore, in the above technical solution, the fixed mounting bracket 30 of the lower straightening roller 20 includes a fixed frame 33 and a support base 34 connected to each other, and the lower straightening roller 20 is rotatably mounted on the support base 34.

[0043] During the equipment installation phase, the fixing frame is fixed on the equipment frame, and then the support base is installed on the fixing frame. Then, the lower straightening roller is installed on the support base through rotating parts such as bearings. When the equipment is running, the motor that drives the lower straightening roller to rotate is driven by the chain to rotate the lower straightening roller on the support base. The friction generated by the rotation of the lower straightening roller drives the angle steel to move along the straightening direction, and at the same time straightens the flange.

[0044] Furthermore, in the above technical solution, the grooves 11 of the upper straightening roller 10 and the lower straightening roller 20 are both concave shapes that match the shape of the angle steel flange, and the grooves 11 of the upper straightening roller 10 and the lower straightening roller 20 are arranged facing each other in the vertical direction. The surfaces of the grooves 11 of the upper straightening roller 10 and the lower straightening roller 20 are provided with spiral guide grooves.

[0045] Before straightening, select a straightening roller of the corresponding specification or adjust the position of the existing straightening roller according to the specifications of the angle steel to ensure that the grooves of the upper and lower straightening rollers are aligned vertically. Place the angle steel between the upper and lower straightening rollers so that the flange of the angle steel is embedded in the groove. Since the groove and the flange are matched, the groove wall and the bottom of the groove apply a uniform straightening force to the flange during the movement of the angle steel, and gradually correct the deformation of the flange.

[0046] Furthermore, in the above technical solution, the chain surrounds the output shaft sprocket of the motor and the sprocket of the lower straightening roller 20, and the motor drives the lower straightening roller 20 to rotate through the chain.

[0047] Furthermore, in the above technical solution, the regulating motor is fixed to the equipment frame by a motor mounting base, and the motor mounting base and the equipment frame are connected by bolts; the motor mounting base includes a base plate and a vertical plate, the base plate is provided with an oblong hole, and the equipment frame is provided with a corresponding threaded hole, and the bolts pass through the oblong hole and engage with the threaded hole to achieve a detachable connection.

[0048] When installing the regulating motor, place the base plate of the motor mounting bracket on the corresponding position on the equipment frame, aligning the oblong hole with the threaded hole. Tighten the bolts through the oblong hole and into the threaded hole to initially secure the motor mounting bracket. Based on the installation position of the lead screw and nut mechanism, fine-tune the position of the motor mounting bracket within the oblong hole range to ensure accurate connection between the regulating motor and the lead screw. Then, tighten the bolts to completely secure the motor mounting bracket. Install the regulating motor onto the upright plate of the motor mounting bracket to complete the installation. When maintenance of the regulating motor is required, simply unscrew the bolts to disassemble the motor mounting bracket and the regulating motor for servicing.

[0049] Furthermore, in the above technical solution, the two ends of the upper straightening roller 10 are respectively mounted on the mounting bracket 30 of the upper straightening roller 10 by bearings, and the two ends of the lower straightening roller 20 are respectively mounted on the mounting bracket 30 of the lower straightening roller 20 by bearings.

[0050] When installing the upper straightening roller, install the bearings on the journals at both ends of the upper straightening roller, and then place the upper straightening roller with the bearings in the corresponding position of the mounting seat of the upper straightening roller mounting bracket, so that the outer ring of the bearing is engaged and fixed with the bearing hole of the mounting seat; the installation steps of the lower straightening roller are the same; when the equipment is running, the straightening roller rotates freely under the support of the bearings, and cooperates to complete the straightening work of the angle steel flange.

[0051] Furthermore, the above technical solution also includes a guide rod for guiding the lifting and lowering of the mounting bracket 30 of the upper straightening roller 10. One end of the guide rod is fixed on the equipment frame, and the other end passes through the mounting bracket 30 of the upper straightening roller 10 and slides in cooperation with the mounting bracket 30 of the upper straightening roller 10; the sliding cooperation is a clearance cooperation.

[0052] When installing the equipment, first fix one end of the guide rod to the equipment frame, then align the guide hole of the upper straightening roller mounting bracket with the guide rod, so that the guide rod passes through the guide hole; during installation, ensure that the gap between the guide rod and the guide hole is within the range of 0.1-0.3mm; when in use, when the adjusting motor drives the screw nut mechanism to raise and lower the upper straightening roller mounting bracket, the guide rod guides the mounting bracket, and the mounting bracket slides smoothly on the guide rod, ensuring that the upper straightening roller is accurately raised and lowered to the appropriate position for angle steel flange straightening.

[0053] Furthermore, in the above technical solution, the upper straightening roller 10 and the lower straightening roller 20 are made of metal materials with a hardness higher than that of angle steel, and the surface of the groove 11 is provided with a wear-resistant coating.

[0054] Specifically, the principle of this utility model is as follows:

[0055] The technical principle of this utility model is based on a series of scientifically sound mechanical structure designs and coordinated operations. From the perspective of power transmission, the motor, as the core power source, is connected to the lower straightening roller sprocket via a chain, stably transmitting the motor's rotational power to the lower straightening roller, thus driving the lower straightening roller to rotate. This chain drive method features a simple structure and reliable transmission, meeting the torque and speed requirements for the lower straightening roller to move the angle steel, ensuring that the angle steel can be fed smoothly and continuously during the straightening process.

[0056] Regarding the adjustment mechanism of the straightening roller, the adjusting motor is connected to a lead screw via its output shaft, and the lead screw is threadedly engaged with a nut fixed on the lifting frame. When the adjusting motor starts, its output shaft drives the lead screw to rotate. Since the nut is fixed on the lifting frame, according to the principle of thread transmission, the rotational motion of the lead screw is converted into the linear lifting motion of the nut and the lifting frame. This lead screw and nut mechanism can accurately convert the rotational motion of the adjusting motor into the linear lifting motion of the upper straightening roller mounting bracket, achieving precise adjustment of the height of the upper straightening roller to meet the straightening requirements of different specifications of angle steel flanges.

[0057] During the straightening process, the groove design of the upper and lower straightening rollers plays a crucial role. The concave shape of the groove matches the shape of the angle steel flange. When the angle steel is placed between the upper and lower straightening rollers, the angle steel flange is embedded in the groove. As the lower straightening roller rotates, the angle steel moves forward under the action of friction. At this time, the groove walls and bottoms of the upper and lower straightening rollers apply uniform pressure to the flange. According to the principle of plastic deformation of materials, under the action of continuous and uniform external force, the angle steel flange undergoes plastic deformation and is gradually straightened to the required shape and dimensional accuracy.
