Description

Technical Field

[0001] This utility model relates to the technical field of metal profile processing equipment, and in particular to an automatic straightening structure. Background Technology

[0002] In the field of metal profile processing, square steel pipes (referred to as square tubes) are widely used in industries such as construction, machinery manufacturing, and furniture, and their straightness requirements are high. However, square tubes often experience deformation problems such as bending, twisting, or local bending during welding, cold bending, or heat treatment due to uneven stress distribution. Traditional straightening equipment is mostly designed for round pipes and is difficult to adapt to the geometric characteristics of square tubes, resulting in the following shortcomings: First, uneven stress on the four sides of the square tube can easily lead to secondary deformation or surface scratches, affecting product quality; second, traditional straightening machines rely heavily on manual adjustment of roller angles and pressure, which is cumbersome, inefficient, and makes it difficult to guarantee straightening accuracy; in addition, existing equipment lacks real-time detection and feedback control of multi-dimensional curvature, making it impossible to achieve automated and continuous production. Therefore, developing an automated straightening device suitable for square tubes to improve straightening accuracy and efficiency and reduce surface damage has become an urgent technical problem to be solved.

The detection and transfer module is mounted on the straightening machine frame and can drive the product placed on the positioning and clamping module to move back and forth so that the inspected product passes through the detection area of ​​the laser displacement detection module. The laser displacement detection module is installed on the bending machine; The upper and lower straightening blocks are mounted on the bending machine and arranged opposite to each other for pressing and straightening the product. The elastic support module is installed on the bending machine and located on both sides of the lower straightening block, and is used to provide support for the product during the straightening process.

[0011] Preferably, the elastic element is one of a helical compression spring, a disc spring, or a rubber elastomer.

[0012] The technical solution of this utility model has the following beneficial effects: High-precision straightening: The deformation of the square tube is detected in real time by the laser displacement detection module, which provides accurate basis for the clamping amount and position of the upper and lower straightening blocks. It supports fixed-point or multi-point composite straightening and effectively copes with various deformation forms such as overall bend, wavy bend and local bend, ensuring straightening accuracy.

[0013] High degree of automation: The detection and transfer module, together with the positioning and clamping module, realizes the automatic clamping, positioning and reciprocating movement of the square tube. Combined with the feedback control of the laser displacement detection module, it significantly reduces manual intervention, improves production efficiency, and is suitable for continuous production.

[0014] Reduce surface damage: The elastic support module uses elastic elements such as helical compression springs, disc springs or rubber elastomers to provide compliant support for the square tube. It adaptively adjusts with the slight changes in the square tube's posture, maintains the stability of the straightening channel, and effectively reduces surface scratches during the straightening process.

[0015] Simple structure and easy to operate: This utility model adopts a modular design, with a clear structure, convenient installation and maintenance, and simple operation, making it suitable for various production scenarios.

[0016] Highly adaptable: Designed for the special geometry of square tubes, the upper and lower straightening blocks are arranged opposite each other to form a straightening channel. Combined with the elastic support module, it can flexibly cope with square tubes of different sizes and bending shapes, and has good versatility.

[0017] In summary, this utility model, by integrating technologies such as laser detection, automatic transplanting, and elastic support, significantly improves the accuracy, efficiency, and product quality of square tube straightening, and solves the problems of low efficiency, poor accuracy, and surface damage of traditional straightening equipment, providing an efficient and reliable solution for the metal profile processing industry.
