Description

Technical Field

[0001] This utility model relates to the technical field of angle steel tower forming devices, and in particular to an angle steel tower forming device with a correction and positioning function. Background Technology

[0002] Power towers, typically trapezoidal or triangular structures, are usually 25-40 meters high and have a steel frame structure. They are often built near power plants and substations in the field. As vital facilities for the power sector, they provide overhead power lines and offer protection and support. Angle steel, also known as angle iron, is used for the corners and edges of power towers. It is a long strip of steel with two perpendicular sides forming an angle. There are equal-sided and unequal-sided angle steels. Equal-sided angle steel has two sides of equal width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components.

[0003] For example, the patent entitled "An Angle Steel Forming Device for Power Tower Processing" (patent application number: CN202222274243.7) discloses an angle steel forming device for power tower processing. By setting an adjustment mechanism, one end of the steel strip is placed on the lower support roller. Then, the stepper motor is started to drive the rotating rod to rotate, which in turn drives the two active bevel gears to rotate synchronously. Since the two active bevel gears mesh with the two driven bevel gears respectively, they drive the two threaded rods to rotate synchronously. Because the axial rotation of the nut block follows and the connecting block is restricted by the opening, the two nut blocks are forced to move down synchronously, which in turn drives the upper pressure roller to move down and press against the steel strip and the lower support roller until the steel strip is squeezed into an angle steel shape. Since the distance between the lower support roller and the upper pressure roller is adjustable, it is convenient to shape steel strips of different thicknesses, and the application range is wider. However, it lacks a correction and positioning structure, and the steel strip is prone to deviation, which affects the forming quality.

[0004] Therefore, it is necessary to propose an angle steel tower forming device with a correction and positioning function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an angle steel tower forming device with a correction and positioning function to solve the problem that the steel strip is prone to displacement due to the lack of a correction and positioning structure, which affects the forming quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an angle steel tower forming device with a correction and positioning function, comprising a gantry frame, a rotating shaft rotatably connected to the gantry frame, a lower support roller fixedly connected to the rotating shaft, an upper pressure roller disposed above the lower support roller, a support frame fixedly connected to the side wall of the gantry frame, a groove being provided on the top of the support frame, the groove being distributed correspondingly to the lower support roller, square grooves being provided on both inner walls of the grooves, a sliding column being slidably disposed inside the square grooves, and a positioning plate being fixedly connected to one end of the sliding column outside the square groove, the two positioning plates cooperating.

[0007] Preferably, rollers are rotatably provided on the side of the two positioning plates that are close to each other.

[0008] Preferably, a limiting block is fixedly connected to one side of each of the two positioning plates that are close to each other, and the limiting block is located at the top of the positioning plate.

[0009] Preferably, a second electric push rod is fixedly connected inside the square groove, and the sliding column is fixedly connected to the telescopic end of the second electric push rod.

[0010] Preferably, a motor is fixedly connected to the outer wall of the gantry frame, and the rotating shaft is fixedly connected to the drive shaft of the motor.

[0011] Preferably, the inner walls on both sides of the gantry are provided with sliding grooves, and sliders are slidably connected inside the sliding grooves. A round rod is fixedly connected between the two sliders, and the upper pressure roller is rotatably connected to the round rod.

[0012] Preferably, a first electric push rod is fixedly connected to the top of the gantry frame, and one of the sliders is fixedly connected to the telescopic end of the first electric push rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This utility model, by setting up a support frame, positioning plate and other structures, can correct and position the steel strip when it is extruded into an angle steel shape. Due to the limiting effect of the positioning plate and rollers, the steel strip can be prevented from deviating and the processing quality can be improved.

[0015] A limit block is installed to limit the steel strip from the top, preventing the steel strip from warping upwards. Attached Figure Description

[0022] This utility model provides, for example Figures 1-5 The angle steel tower forming device with correction and positioning function shown includes a gantry frame 1, a rotating shaft 2 rotatably connected to the gantry frame 1, a lower support roller 3 fixedly connected to the rotating shaft 2, a motor 17 fixedly connected to the outer wall of the gantry frame 1, the rotating shaft 2 fixedly connected to the drive shaft of the motor 17, and the motor 17 drives the lower support roller 3 to rotate through the rotating shaft 2; an upper pressure roller 8 is provided above the lower support roller 3, and sliding grooves 4 are provided on both inner walls of the gantry frame 1, with sliding blocks 5 slidably connected inside the sliding grooves 4, and a round rod 6 fixedly connected between the two sliding blocks 5, and the upper pressure roller 8 rotatably connected to the round rod 6.

[0023] A first electric push rod 7 is fixedly connected to the top of the gantry frame 1, and one of the sliders 5 is fixedly connected to the telescopic end of the first electric push rod 7. When the telescopic end of the first electric push rod 7 extends, it will drive the round rod 6 and the upper pressure roller 8 to move downward through the slider 5.

[0024] When processing steel strip into angle steel: First, place one end of the steel strip on the lower support roller 3, and control the extension end of the first electric push rod 7 to extend. When the extension end of the first electric push rod 7 extends, it will drive the round rod 6 and the upper pressure roller 8 to move downward through the slider 5. The upper pressure roller 8 cooperates with the lower support roller 3 to press the steel strip until it is squeezed into an angle steel shape. Moreover, due to the adjustable distance between the upper pressure roller 8 and the lower support roller 3, it is convenient to shape steel strips of different thicknesses.

[0025] Motor 17 drives the lower roller 3 to rotate via shaft 2, and the steel strip is automatically conveyed and displaced, thereby performing automatic angle steel forming processing. The processing efficiency is fast and it is easy to assemble into an angle steel tower.

[0026] To prevent the steel strip from shifting, a support frame 9 is fixedly connected to the side wall of the gantry frame 1. The top of the support frame 9 has a groove 10, which is distributed correspondingly to the lower roller 3. Square grooves 11 are provided on both inner walls of the groove 10. A sliding column 12 is slidably arranged inside the square groove 11. A positioning plate 13 is fixedly connected to one end of the sliding column 12 outside the square groove 11. The two positioning plates 13 cooperate, and rollers 14 are rotatably arranged on the side of the two positioning plates 13 that are close to each other. Multiple rollers 14 are provided to reduce the wear between the steel strip and the positioning plate 13.

[0027] The square groove 11 is fixedly connected to the second electric push rod 16, and the sliding column 12 is fixedly connected to the telescopic end of the second electric push rod 16.

[0028] The steel strip is passed between the two positioning plates 13 and abuts against the bottom of the groove 10. At the same time, the second electric push rods 16 on both sides are activated, and the telescopic ends of the second electric push rods 16 are extended, driving the positioning plates 13 to move towards the steel strip. The rollers 14 are attached to the steel strip without affecting the rotation of the rollers 14. When the steel strip is extruded into an angle steel shape, the positioning plates 13 and rollers 14 can correct and position the steel strip, prevent the steel strip from deviating, and improve the processing quality.

[0029] In practical use, a pressure sensor can be set up to cooperate with the second electric push rod 16 to monitor the extrusion pressure between the roller 14 and the steel strip. The roller 14 is attached to the steel strip and does not affect the rotation of the roller 14, thus avoiding affecting the movement of the steel strip. The pressure sensor and its working principle are common existing technologies and will not be described in detail here.

[0030] Meanwhile, rollers 14 can also be installed at the bottom of the groove 10 to reduce wear.

[0031] To prevent the steel strip from warping upwards, limit blocks 15 are fixedly connected to the sides of the two positioning plates 13 that are close to each other, and the limit blocks 15 are located at the top of the positioning plates 13. The limit blocks 15 are set so that the top of the steel strip can limit it and prevent the steel strip from warping upwards.
