Description

Technical Field

[0001] The utility model relates to a steel member bending device. Background Art

[0002] Steel components refer to composite components of steel structures formed by processing materials such as steel plates and channel steels. In the process of building the iron tower, in addition to the steel pipes and angle steels as the main body, steel components are also needed as connecting and reinforcing parts. These steel components often need to be bent according to actual needs. The bending device in the prior art usually includes a base and a folding part. The steel component is above the base, and a bending groove is provided on the base. The folding part is arranged above the bending groove, and the folding part can be vertically pressed on the steel component and pressurized to cause it to bend. However, in the bending process of the prior art, as the folding part moves downward, the contact between the steel component and the base will change from surface contact to line contact during the bending and deformation process, and the load-bearing capacity will be greatly weakened, resulting in indentations, which affect the appearance and performance of the product. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a steel member bending device, which can avoid leaving indentations and ensure the performance and appearance of the product.

[0004] To achieve the above-mentioned purpose, the utility model provides a steel member bending device, including a base and a folding portion, the folding portion can be vertically pressed on the steel member and apply pressure to cause it to bend, and also includes an anti-indentation component, the base is provided with a bending groove and movable grooves located on both sides of the bending groove, the bending groove is for the steel member to extend into when bending, the anti-indentation component includes two abutment blocks, the two abutment blocks are swingably set at the two movable grooves respectively, and the abutment blocks include a fitting surface, the fitting surfaces of the two abutment blocks can be reset to a flat state with the two abutment blocks, or can be swung to a V-shaped groove state with a notch at the bottom with the two abutment blocks.

[0005] The advantage of adopting the above technical solution is that an anti-indentation component is arranged on the basis of setting a base and a folding part, and the fitting surfaces on the abutment blocks respectively arranged at the two movable grooves in the anti-indentation component are swung to fit with the steel member. In the process of bending the steel member, when the folding part presses vertically downward on the steel member to apply pressure to it, the steel member gradually deforms. At this time, the abutment block fitting the steel member is also subjected to force, and swings with the deformation of the steel member, always maintaining a state of fitting the steel member. Since the steel member is always in contact with the fitting surface during the deformation process to ensure its own bearing capacity, it will not deform and leave indentations, thereby ensuring the performance and appearance of the product during subsequent use.

[0006] The utility model can be further configured as follows: the abutment block comprises a bottom portion fitted to the movable groove, the bottom portion is configured in a semi-cylindrical shape, and the centers of the two ends of the bottom portion are rotatably connected to the movable groove.

[0007] Through further configuration, a semi-cylindrical bottom is provided on the abutment block, and the center points at both ends of the bottom are rotatably connected to the movable groove, so that the fitting surface of the abutment block can move circumferentially along the center point of the bottom, better conforming to the bending trajectory of the steel component, and allowing the fitting surface to better conform to the movement of the steel component.

[0008] The utility model can be further configured as follows: the abutment block includes an extension portion, the base includes an upper end surface and an elastic member located on both sides of the movable groove, the extension portion can swing with the abutment block to abut against the upper end surface of the base, and the extension portion and the elastic member are detachably connected.

[0009] Through further configuration, an extension portion is provided on the abutment block, and an upper end surface and an elastic member located on both sides of the movable groove are provided on the base, so that the extension portion can form elastic reset by connecting with the elastic member, and can also achieve a limiting effect by abutting against the upper end surface of the base.

[0010] The utility model can be further configured as follows: a placement groove and a locking groove are provided on the outer wall of the elastic member on one side of the placement groove, the elastic member is a spring, and a clamping block is provided on the upper end of the elastic member, the clamping block and the elastic member can extend into the placement groove and the locking groove respectively, and one end of the locking groove is provided at the opening of the placement groove, and the other end of the locking groove is bent and extends to the middle of the outer wall on one side of the placement groove.

[0011] Through further configuration, a placement groove and a locking groove are provided on the outer wall of one side of the elastic member corresponding to the placement groove on the side of the extension part facing the upper end surface of the base, and a card block is provided at the upper end of the elastic member and is provided as a spring, so that the card block and the elastic member can be placed respectively through the placement groove and the locking groove, and finally one end of the locking groove is provided at the opening of the placement groove, and the other end is bent and extended to the middle part of the outer wall on one side of the locking groove, and the card block is limited by the spring of the bent and extended locking groove to prevent it from falling out of the placement groove, thereby ensuring the connection between the locking groove and the card block, and when replacing, the spring can be slid out along the locking groove first, and then the card block can be driven out of the placement groove, so as to facilitate replacement.
