Description

Technical Field

[0001] The present application relates to the field of steel structure processing devices, and in particular to a correction device for steel structure processing. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, constructed from sections and plates. Rust removal and prevention processes include silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components are typically connected using welds, bolts, or rivets. During fabrication, steel structures often bend and deform due to cooling and transportation, necessitating structural correction.

[0003] Reference Figure 1 The steel structure includes a main board 20 and two side panels 25. The two side panels 25 are welded and fixed on both sides of the radial direction of the main board 20. The end of the main board 20 is located at the radial midpoint of the side panel 25. The length direction of the side panel 25 is parallel to the length direction of the main board 20, and the radial direction of the main board 20 and the radial direction of the side panel 25 are perpendicular to each other.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the steel structure is bent and deformed after cooling and transportation, the steel structure needs to be corrected by a straightening machine. The existing straightening wheel can only roll and correct the end face of the main board, so that the bending deformation of the side panel cannot be solved, thereby reducing the processing quality of the steel structure. Summary of the Invention

[0005] In order to improve the processing quality of steel structures, the present application provides a correction device for steel structure processing.

[0006] This application provides a correction device for steel structure processing, which adopts the following technical solution:

At the same time, both ends of the third pressure roller axis are rotated and connected to the outer walls of the upper and lower pressure plates facing each other, and the third pressure roller surface is pressed against the outer wall of the side plate, so that the steel structure is not easy to separate from the upper and lower pressure plates, and the steel structure is fixed on the upper and lower pressure plates. The first driving member drives the second pressure roller to rotate, and the friction force between the second pressure roller and the steel structure drives the steel structure to move on the surface of the second pressure roller. At the same time, the friction force between the outer wall of the steel structure and the first and third pressure rollers drives the first and third pressure rollers to rotate, so as to achieve simultaneous rolling and correction of the outer walls of the main plate and the side plate, so that the outer wall of the steel structure is restored to be flat, thereby improving the production quality of the steel structure.

[0009] Optionally, a circulation annular cavity is coaxially opened in each of the plurality of second pressing rollers, the circulation annular cavity is close to the outer wall of the second pressing roller, and the circulation annular cavity is used to accommodate cooling liquid.

[0010] By adopting the above technical solution, when the second pressure roller rolls and corrects the outer wall of the main board, the outer wall of the second pressure roller and the outer wall of the main board generate heat through friction, so that the energy of the first driving member to the second pressure roller is partially converted into friction internal energy, so that the power of the second pressure roller is reduced, and the coolant circulating in the annular cavity cools the outer wall of the second pressure roller, so that the second pressure roller is not easy to have a high temperature, so that the energy of the first driving member to the second pressure roller is not easy to be converted into friction internal energy, thereby reducing the loss of heat energy and improving the rolling efficiency of the second pressure roller.

[0011] Optionally, a plurality of the second pressure rollers are coaxially provided with a accommodating cavity, the accommodating cavity is used to accommodate cooling liquid, a first thermal expansion and contraction block is provided on the inner wall of the accommodating cavity, a plurality of connecting holes are provided on the end face of the lower pressure plate facing the upper pressure plate, and the plurality of connecting holes are connected to the plurality of accommodating cavities in a one-to-one corresponding axial direction, and a closing member for opening and closing the accommodating cavity is provided on the lower pressure plate.

The second pressure roller transfers the internal energy heat to the first thermal expansion and contraction block. The first thermal expansion and contraction block heats up and deforms, and drives the coolant in the accommodating cavity into the connecting hole. The coolant in the connecting hole cools the lower pressure plate, making it less likely for the lower pressure plate to heat up and deform, thereby improving the rotation stability of the second pressure roller on the lower pressure plate.

A connecting hole is provided on the adjustment plate, and the connecting hole passes through the adjustment plate.

When the second thermal expansion and contraction block heats up and deforms, the adjustment plate is driven to slide in a direction close to the axis of the connecting hole, and the accommodating cavity, the connecting hole and the connecting hole are connected in sequence.

[0014] By adopting the above technical solution, the adjusting plate separates the communicating hole and the accommodating cavity, so that the cooling liquid in the accommodating cavity is not easily contacted with the air through the communicating hole, and the cooling liquid in the accommodating cavity is not easily volatilized, thereby reducing the loss of material; when the lower pressure plate heats up and transfers the internal energy heat to the second thermal expansion and contraction block, the second thermal expansion and contraction block heats up and deforms, and drives the adjusting plate to slide toward the axis of the communicating hole, and the accommodating cavity, the connecting hole and the communicating hole are connected in sequence.

When the first thermal expansion and contraction block heats up and deforms, the first thermal expansion and contraction block drives the coolant in the accommodating cavity to enter the connecting holes and the circulation holes in turn, and the coolant drives the air in the connecting holes and the circulation holes to be discharged from the circulation holes. The circulation holes are located between adjacent first pressure rollers, and the coolant in the circulation holes cools the upper pressure plate close to the first pressure roller, so that the upper pressure plate is not easily heated up and deformed, thereby improving the rotation stability of the first pressure roller and the upper pressure plate.

[0017] Optionally, a plurality of elastic blocks are provided on the circumferential inner wall of the circulation hole close to the lower pressing plate, and the plurality of elastic blocks are spliced ​​together to form a circular plate and seal the circulation hole.

[0018] By adopting the above technical solution, when the lower pressure plate cools down, the first thermal expansion and contraction block cools down and deforms, and drives the coolant in the circulation hole and the connecting hole to flow back into the storage cavity. The upper pressure plate slides in the direction away from the lower pressure plate, and multiple elastic blocks are spliced ​​to form a circular plate and close the circulation hole, so that the coolant remaining in the circulation hole is not easy to overflow from the circulation hole toward the groove of the lower pressure plate, thereby keeping the base clean and reducing the number of times the staff cleans the base.

[0019] Optionally, it also includes multiple abutment blocks, which are arranged one-to-one above the multiple connecting holes, and the outer walls of the multiple abutment blocks are provided with abutment holes, which are connected to the connecting holes.

The abutment blocks squeeze the elastic blocks and drive the elastic blocks to deform, so that the sealing effect of the flow holes disappears, and the flow holes are connected to the connecting holes.
