Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending dies, in particular to a square pipe bending die. Background Technique

[0002] Pipe bending is carried out by using a complete set of bending equipment, which is divided into two processes: cold bending and hot pushing. No matter which kind of machine equipment and pipeline, most of them use pipe bending, mainly for oil transportation, gas transportation, liquid transportation, engineering bridge construction, etc.

[0003] In the traditional pipe bending production process, a pipe bending die is required to produce pipe bending products. During the process of using the die to produce products, due to the deformation of the pipe orifice and caliber during pipe bending, it is difficult to take out the bent pipe from the die, and it is difficult to process the pipe blank into a bent pipe. The processing difficulty is large, and the error of geometric shape and dimensional accuracy is large.

[0004] Therefore, we need to provide a new type of square pipe bending die. Content of the Utility Model

[0005] The purpose of the utility model is to provide a square pipe bending die to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a square pipe bending die, including a moving core die, the side of the moving core die is T-shaped, and a fixed clamping block is arranged outside the moving core die.

[0007] Preferably, a groove is opened on the side wall of the moving core die, and a convex tenon is integrally formed on one side of the fixed clamping block.

[0008] Preferably, the convex tenon is in snap-fit with the groove.

[0009] The utility model provides a square pipe bending die. It has the following beneficial effects:

[0010] (1). By setting the moving core die, the utility model can effectively reduce the caliber deformation problem during pipe bending, improve the production quality and efficiency of pipe bending products, improve the precision and efficiency of square pipe bending processing, reduce the production cost, and at the same time reduce the complexity during the operation process, facilitating the operator to perform accurate positioning.

[0011] (2) The utility model makes the connection between the fixed clamping block and the moving die more firm and reliable through the design of the convex tenon, effectively avoiding the loosening phenomenon during the production process and improving the service life of the overall equipment. In addition, the application of the anti-wrinkle die significantly reduces the wrinkle problem of the square tube during the bending process, ensures the appearance quality of the product, meets the high-precision production requirements, and the design of the square tube forming cavity is reasonable, enabling the square tube 2 to move stably during the forming process, further optimizing the forming process and improving the production efficiency.

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0017] The preferred embodiment of the square tube bending die provided by the present utility model is as Figure 1-2As shown: The square tube bending die includes a moving core die 11. The side of the moving core die 11 is T-shaped, and a fixed clamping block 12 is arranged outside the moving core die 11. A groove is formed in the side wall of the moving core die 11. A convex tenon 121 is integrally formed on one side of the fixed clamping block 12. The convex tenon 121 is engaged and matched with the groove. A guiding die 14 is fixedly arranged at one end of the fixed clamping block 12. An anti-wrinkle die 13 is fixedly arranged on the other side wall of the moving core die 11. A square tube forming cavity is arranged between the moving core die 11 and the fixed clamping block 12, and a square tube 2 is arranged in the square tube forming cavity. This technical solution effectively improves the accuracy and efficiency of square tube bending processing, reduces production costs, and at the same time reduces the complexity in the operation process, facilitating accurate positioning by the operator; the design of the convex tenon 121 makes the connection between the fixed clamping block 12 and the moving core die 11 more firm and reliable, effectively avoiding loosening during the production process and enhancing the service life of the overall equipment. In addition, the application of the anti-wrinkle die 13 significantly reduces the wrinkle problem of the square tube during the bending process, ensuring the appearance quality of the product and meeting the high-precision production requirements. The design of the square tube forming cavity is reasonable, enabling the square tube 2 to move stably during the forming process, further optimizing the forming process and improving production efficiency.

[0018] During use, the user places the guiding die 14 at the desired bending position, and then starts the device. The moving die 11 then begins to work, driving the square tube 2 to complete the bending process within the forming cavity. Throughout the process, the fixed clamping block 12 firmly holds the square tube in place, ensuring the accuracy of the bending angle. The design of the square tube bending die is ingenious and practical. It mainly consists of several key components to ensure the precise forming of the square tube. First of all, the moving die 11 is the core part of the entire device. Its side is designed in a unique T-shaped structure. This design not only enhances the structural stability but also facilitates the connection and cooperation with other components. On the outer side of the moving die 11, a fixed clamping block 12 is carefully arranged. The function of this clamping block is to fix and position the square tube, ensuring that the position of the square tube does not shift during the bending process. To further enhance the clamping effect, a convex tenon 121 is integrally formed on one side of the fixed clamping block 12. This convex tenon 121 fits perfectly with the groove opened on the side wall of the moving die 11, forming a precise clamping mechanism. This design not only improves the reliability of clamping but also ensures that the square tube does not slide or misalign during the bending process. In addition, a guiding die 14 is fixedly arranged at one end of the fixed clamping block 12. The function of the guiding die 14 is to guide the movement trajectory of the square tube during the bending process, ensuring the accuracy of the bending angle and shape. On the other side wall of the moving die 11, a wrinkle-proof die 13 is fixedly arranged. The function of this wrinkle-proof die is to prevent the surface of the square tube from generating wrinkles or deformation during the bending process, thus ensuring that the formed square tube has a good appearance and structural integrity. Between the moving die 11 and the fixed clamping block 12, a cavity specifically for forming the square tube is designed, which we call the square tube forming cavity. The interior of this cavity is carefully designed to accommodate square tubes of different sizes and specifications. The square tube forming cavity contains the square tube 2, which is the workpiece to be formed. During the bending process, the square tube 2 will be accurately positioned and fixed within the square tube forming cavity, and through the coordinated action of the moving die 11 and the fixed clamping block 12, precise bending and forming are achieved. The design of the entire square tube bending die fully considers the convenience of operation, the accuracy of forming, and the reliability of use, ensuring that high-quality square tube products can be continuously and stably provided in mass production.

[0019] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
