Example 1

[0021] In order to improve the correction efficiency of H-beam flange correction equipment, a H-beam flange hydraulic correction machine is designed. The specific scheme is as follows:

[0022] like Figure 1-2 As shown, a hydraulic straightening machine for an H-beam flange comprises a base 2, wherein a first straightening mechanism and a second straightening mechanism are respectively arranged in the front and rear directions of the base 2, wherein the first straightening mechanism and the second straightening mechanism are respectively used to straighten the flanges on both sides of the H-beam, wherein the first straightening mechanism and the second straightening mechanism are both provided with two straightening wheels 8, wherein the straightening wheels 8 of the first straightening mechanism and the second straightening mechanism are staggered to avoid mutual interference, wherein two sets of stable guide wheels 9 are respectively arranged in the front and rear directions of the straightening wheels 8 to keep the H-beam moving stably, and wherein the two straightening wheels 8 are arranged opposite to each other up and down to straighten the upper and lower parts of the flange on the same side.

[0023] A control component is provided on one side of the base 2. The control component includes an angle-adjustable control screen and a remote controller.

The stabilizing guide wheel 9 is adjusted up and down by the extension and retraction of the hydraulic cylinder. A stabilizing guide wheel 9 is provided in the front and rear directions of the correction wheel 8 located above. When the H-shaped steel moves, the stabilizing guide wheel 9 contacts the edge of the flange to prevent the H-shaped steel from shaking up and down.

[0025] Vertical guide wheels 10 are provided at the feed inlet and the discharge outlet of the first correction mechanism and the second correction mechanism. The vertical guide wheels 10 are used to contact the outer sides of the flange plates on both sides of the H-beam to ensure that the H-beam will not deviate left and right.

[0026] The correction wheel 8 is connected to a lifting drive 802 for controlling the height of the correction wheel 8. The correction wheel 8 is located at the bottom of the mounting structure 801. The correction path is rotationally connected to the telescopic end of the lifting drive 802. The lifting drive 802 adopts a hydraulic cylinder, which is installed inside the slide seat. A detachable cover is provided on the top of the hydraulic cylinder, which is used to cover the mounting structure 801 after the hydraulic cylinder is installed.

[0027] The first correction mechanism and the second correction mechanism are both provided with a horizontal adjustment drive 201 to control the horizontal displacement of the first correction mechanism and the second correction mechanism.

[0028] A base 1 is provided at the bottom of the base 2, and the base 2 is slidably connected to the base 1. A horizontal adjustment drive 201 is provided on the base 1. The adjustment drive 201 adopts a hydraulic cylinder. The main body of the hydraulic cylinder is installed on the base 1, and the front end of the hydraulic cylinder is connected to the base 2. The advance and retreat of the base 2 is controlled by the extension and retraction of the hydraulic cylinder. The horizontal displacement of the base 2 causes the first correction mechanism and the second correction mechanism to be displaced.

[0029] Sliding parts are provided at the lower edge parts and the bottom of both sides of the base 2. Correspondingly, the base 1 is provided with sliding grooves matching the sliding parts, so that the base 2 can move more smoothly and stably.

[0030] An outwardly protruding mounting structure 801 is provided on the base 2 for mounting the correction wheel 8. An mounting space is provided inside the mounting structure 801 for mounting a lifting drive 802 for mounting the correction wheel 8. The mounting structure 801 and the base 2 are an integrated structure to ensure structural strength.

[0031] The base 2 is also provided with a driving wheel, which is connected to a driving assembly. The driving wheel corresponds to the side of the middle plate of the H-shaped steel. The driving wheel is rotated by the driving assembly to enable the H-shaped steel to move forward and backward.

[0032] The driving assembly includes a conveying drive 7 and a driving shaft 5 . The conveying drive 7 is connected to the driving shaft 5 , and a driving wheel is mounted on the driving shaft 5 .

[0033] A movable mounting seat 3 is provided in the base 2, and the upper and lower parts of the mounting seat 3 are slidably connected to the base 2. The rear part of the mounting seat 3 is connected to an advance and retreat drive 4 to control the forward and backward movement of the mounting seat 3. The mounting seat 3 is used to install the drive component. The advance and retreat drive 4 adopts a hydraulic motor. The output end of the hydraulic motor is connected to a screw rod, and the other end of the screw rod is connected to the mounting seat 3. The operation of the hydraulic motor controls the mounting seat 3 to perform fine adjustments within a short distance.

[0034] The base 2 is in a U-shaped structure, and the middle portion is used to place the mounting seat 3, and the mounting seat 3 is in a rectangular parallelepiped structure as a whole.

[0035] The driving wheel is rotated by the conveying drive 7, so that the H-beam is moved forward or backward, and the correction wheel 8 corrects the flange of the H-beam. The conveying drive 7 adopts a hydraulic motor. A coupling 6 is installed between the hydraulic motor and the driving shaft 5. The coupling 6 is fixedly installed on the top of the mounting seat 3. A stabilizing bearing 302 is respectively provided on the upper and lower sides of the driving wheel. The hydraulic motor drives the driving shaft 5 to rotate the driving wheel. The forward and backward drive 4 adopts a hydraulic cylinder or a screw motor assembly. Through the forward and backward drive 4, the entire mounting seat 3, the driving assembly and the driving wheel are moved closer to or away from the H-beam, so as to adapt to H-beams of different sizes.

[0036] Working principle:

[0037] In actual processing, roller conveyors are provided in front and rear of the straightening machine for conveying H-shaped steel. When the first and second straightening mechanisms are in their initial state, they are close to each other, and the straightening wheels 8 of the first and second straightening mechanisms can be located on the same straight line front and back. When the front end of the H-shaped steel is located below the straightening wheel 8, the position of the straightening wheel 8 and the driving wheel are adjusted to make the straightening wheel 8 abut against the inner side of the flange, and the driving wheel abut against both sides of the H-shaped steel. The driving wheel rotates to move the H-shaped steel forward, and the straightening wheel 8 corrects the flange. If the correction effect is uncertain, the H-shaped steel can be moved forward and backward once respectively, that is, it is corrected twice.

[0038] The straightening machine of the present invention can complete the straightening processing of the flange of the H-beam at one time when the H-beam passes through the straightening machine, without the need to flip over to correct the flange on the other side like the traditional straightening machine, so the processing efficiency is higher and the time is shorter; the straightening machine is provided with a first straightening mechanism and a second straightening mechanism which can be adjusted horizontally, the straightening wheel 8 can be adjusted up and down, and the driving wheel can be adjusted forward and backward, so it can be adapted to a variety of H-beams for straightening operations, and has a wider applicability. Example 2

[0039] In this embodiment, the structural composition of the straightening machine is basically the same as that of Embodiment 1, with the difference that the first straightening mechanism and the second straightening mechanism are both provided with four straightening wheels 8, each straightening wheel 8 is provided with an auxiliary straightening wheel, and the auxiliary straightening wheel is slidably mounted on the bottom of the mounting structure 801. The auxiliary straightening wheel is also provided with a telescopic drive for controlling the distance from the straightening wheel 8. During correction, the flange of the H-beam is located between the straightening wheel 8 and the auxiliary straightening wheel, which can improve the correction effect of the H-beam. Example 3

[0040] In this embodiment, the structure of the straightening machine is basically the same as that of Embodiment 1, except that the portion on the mounting structure 801 for mounting the straightening wheel 8 can be opened outward to facilitate disassembly and assembly of the structural components of this portion. To ensure the strength of use, the connection method of this portion adopts a combination of a latch and a screw to ensure that this portion will not loosen.
