Description

Technical Field

[0001] The present invention relates to the technical field of H-beam straightening, and particularly to a multi-flange H-beam gantry straightening machine. Background Technique

[0002] Conventional H-beams are welded by two flange plates and one web plate. Due to the principle of thermal expansion and contraction of the weld, the angle between the flange plates and the web plate is deformed. Therefore, correction equipment is needed to straighten the components. However, with the development of various industries, in order to obtain components with higher unidirectional strength and smaller width, a multi-flange H-beam component has emerged, and its application fields include steel structure fields such as ships and integrated buildings. The multi-flange H-beam is welded by three or more flange plates and one web plate.

[0003] Existing straightening equipment cannot straighten the flange plates of this multi-flange H-beam component because the flange plates to be straightened are not only limited to the outermost two sides. On the other hand, the rib straightening machine in the traditional shipbuilding industry cannot straighten the flange plates with larger thickness. Therefore, it is necessary and practically valuable to develop a straightening machine that can straighten multi-flange H-beam components. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-flange H-beam gantry straightening machine to solve the problems raised in the above background technique.

A straightening main machine is arranged on the right side of the guiding device. The guiding device includes a base. Servo drives are arranged at both ends of the base. Ball screw drives are fixedly connected to the opposite sides of the servo drives. Slide rail guides are fixedly connected to both sides of the top of the base. A gantry frame is movably connected to the outer wall of the slide rail guides. Flange wheels are arranged in the inner cavity of the gantry frame. Web rollers are arranged on the opposite sides of the gantry frame.

[0006] Preferably, the straightening main machine includes a main frame and a lifting mechanism. A fixed steel plate is fixedly connected to the top of the main frame.

A power cylinder is arranged on the right side of the track. An upper straightening unit is movably connected to the outer wall of the track. A lower straightening unit is arranged at the bottom of the inner cavity of the main frame.

[0007] Preferably, the upper correction unit and the lower correction unit are symmetrically arranged. A servo motor is arranged at the bottom of the lower correction unit. The upper correction unit includes a machine base. A lifting drive is arranged at the top of the machine base. A motor reducer is arranged at the back of the lifting drive. Four groups of oil cylinders are arranged at the four corners of the top of the machine base. A side pressing oil cylinder is fixedly connected to the front of the machine base. A top wheel is arranged at the bottom of the machine base. A guide rod is fixedly connected to the bottom of the lifting drive. A tapered wheel is fixedly connected to the bottom of the guide rod. A pressing wheel is arranged below the oil cylinder.

[0008] Preferably, the motor reducer is driven by a hydraulic motor connected to a planetary gear reducer. The pressing wheel adopts a double-sided pressing wheel structure, and its guide shaft is guided by a guide key and a scale is arranged on the other side.

[0009] Preferably, the lifting drive mechanism of the upper correction unit is driven by a hydraulic cylinder, and the lifting drive mechanism of the lower correction unit is driven by a servo motor to drive the screw rod to lift, wherein the lifting drive provides power drive with a 2.5-ton lifting drive.

[0012] 1. For this multi-wing H-shaped steel gantry straightening machine, the guiding device is composed of 1 set of base and 2 sets of guiding wheel mechanisms. The 2 sets of guiding wheel structures are arranged oppositely.

[0037] In this embodiment, when the upper correction unit 15 makes a horizontal adjustment, the lower correction unit 16 needs to make a corresponding adjustment so that the upper and lower correction units correspond to each other.

[0038] Working principle: PEC steel structures are mainly divided into 3 categories: two-panel components, three-panel components, and four-panel components. According to the number and order of flange plates of different components, the flange plates to be corrected are defined as the reference flange plate, the second flange plate, and the third flange plate. The gantry straightening machine divides the straightening units into unit A and unit B according to the position of the flange plate to be corrected, and defines unit A as right deviation straightening and unit B as left deviation straightening;

[0039] The portal straightening machine consists of 2 sets of straightening main machines and 3 sets of guiding devices. The reference wing plate of the PEC component must be right-offset, so it is set as Unit A; the second wing plate of the components in the second grid and the third grid must be left-offset, so Unit B is set at the position adjacent to the reference wing plate; the second wing plate of the components in the fourth grid may be left-offset or right-offset, so Unit A and Unit B are set at intervals at the position of the second wing plate; the third wing plate of the components in the fourth grid must be left-offset. Before the component enters the straightening station through the front roller table, all components of the guiding device 1 of the straightening machine and the straightening main machine 2 must reach the specified positions in advance according to the input component size. A fixed steel plate 10 is fixedly connected to the top of the main frame 201. A synchronous shaft 11 is fixedly connected to the opposite side of the fixed steel plate 10. An elevator 12 is arranged on the top of the fixed steel plate 10. A lifting beam 13 is fixedly connected to the bottom of the elevator 12. A lifting guide column 14 is fixedly connected to the bottom of the lifting beam 13. The middle part of the bottom of the lifting beam 13 is movably connected with an upper straightening unit 15. A lower straightening unit 16 is arranged at the bottom of the inner cavity of the main frame 201. The lifting beam 13 is guided by a cylinder and synchronously lifted at two points. The lifting drive adopts a screw jack 12. A side push oil cylinder 27 and a slide rail 28 are arranged below the lifting beam 13. The slide rail 28 cooperates with the upper straightening unit 15 to adjust the lateral position of the upper straightening unit 15. When the upper straightening unit 15 is laterally adjusted, the lower straightening unit 16 needs to be adjusted accordingly so that the upper and lower straightening units correspond to each other. After that, the component is conveyed by the front roller table through the first guiding device 1 into the first group of straightening main machines 2. When the component enters or leaves the straightening station, reference guiding is required to enable the component to accurately enter the straightening main machine 2 according to the preset size, and ensure that the wing plate to be straightened accurately enters the corresponding straightening unit, and the reference wing plate enters the first straightening unit in sequence, and the second wing plate enters the second straightening unit. Then, the component is conveyed by the shaping wheel through the second guiding device into the second group of straightening main machines 2, and the third wing plate is input into the third straightening unit in sequence, and the second wing plate enters the fourth straightening unit according to actual needs. Among them, the components in the fourth grid with a wing plate thickness < 12 mm can continuously pass through the second straightening unit and the fourth straightening unit, and the components in the fourth grid with a wing plate thickness > 12 mm need to select the corresponding pass straightening unit according to the deviation of the second wing plate.
