Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically a rotary round steel bending mechanism. Background Technology

[0002] Metalworking (also known as metal processing or metalworking of the general term) refers to the production activities of humans processing materials composed primarily of metallic elements or possessing metallic properties. It is a technological process that transforms metallic materials into items, parts, and components, encompassing large parts for bridges and ships, as well as intricate components for engines, jewelry, and watches. It is widely used in various fields such as science, industry, art, and handicrafts. In the metalworking industry, bending round steel bars is a common processing technique.

[0003] However, existing bending mechanisms typically bend the tube directly during actual use. Because the mold comes into partial contact with the tube during bending, the stress area is small and the pressure is concentrated, which can easily cause damage such as indentations, dents, or even thinning of the tube wall. At the same time, if the bending angle and force are not properly controlled, stress concentration will be aggravated, affecting the structural strength and appearance quality of the tube and creating hidden dangers for subsequent processing and use.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a rotary round steel bending mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a rotary round steel bending mechanism to address the problems mentioned in the background section. Existing bending mechanisms typically bend the steel directly during actual use. Because the die and the round tube come into partial contact during bending, the small force area and concentrated pressure easily cause damage such as indentations, dents, or even thinning of the tube wall. Furthermore, improper control of the bending angle and force can exacerbate stress concentration, affecting the structural strength and appearance quality of the round tube, creating potential problems for subsequent processing and use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary round steel bending mechanism, comprising an upper template, a punch, a rotating block, a spring, a rotating bracket, a lower template, a spring fixing pin, a rotating block spring fixing pin, and a round tube. The punch is locked onto the upper template, the rotating block is clamped inside the rotating bracket, the rotating block spring fixing pin passes through the rotating block and is fastened to the rotating block, the spring fixing pin is fixed to the rotating bracket, the spring is hung between the spring fixing pin and the rotating block spring fixing pin, and the rotating bracket is locked onto the lower template.

[0007] Furthermore, the number of springs is four, and they are arranged symmetrically.

[0008] Furthermore, the rotating block spring fixing pins are in two sets, with two pins in each set.

[0009] Furthermore, a groove is provided at the middle of the top of the rotating bracket, and the surface of the circular tube contacts the inner cavity of the groove.

[0010] Furthermore, a bending head is provided at the bottom of the punch.

[0011] Furthermore, the bottom of the lower template is provided with an anti-slip pad, and the bottom of the anti-slip pad is provided with anti-slip texture.

[0012] Furthermore, the spring fixing pin (7) is cylindrical and symmetrical on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Compared with existing technologies, this rotary round steel bending mechanism, through the cooperation of the upper template and the punch, combined with the groove on the top of the rotating bracket and the fitting design of the round tube, can achieve precise positioning and force application on the round tube, ensuring that the bending angle and dimensions meet the requirements. Simultaneously, the linkage structure between the spring and the rotating block can adaptively adjust according to the actual force on the round tube during the bending process, effectively improving bending efficiency and accuracy. The rotating block has a large contact area with the surface of the round tube, and the spring acts as a buffer, evenly distributing pressure during bending, reducing the probability of indentations, scratches, and other damage to the surface of the round tube, and ensuring the appearance quality and surface integrity of the round tube.

[0015] 2. Compared with existing technologies, this rotary round steel bending mechanism, through four symmetrically arranged springs and two sets of rotating block spring fixing pins, ensures that the rotating support maintains a stable force state during bending, thus enhancing the stability of the entire bending mechanism. Simultaneously, the fixing effect of the spring fixing pins and the rotating block spring fixing pins effectively prevents the springs from shifting or falling off during operation, ensuring the reliability and safety of the mechanism's operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Meanwhile, the equipment in this application are all conventional instruments, and their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. They are all controlled by remote control switches. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail. The scale of the accompanying drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0023] Example 1: As Figures 1-4 As shown, a rotary round steel bending mechanism includes an upper template 1, a punch 2, a rotating block 3, a spring 4, a rotating bracket 5, a lower template 6, a spring fixing pin 7, a rotating block spring fixing pin 8, and a round tube 9. The punch 2 is locked onto the upper template 1, the rotating block 3 is clamped inside the rotating bracket 5, the rotating block spring fixing pin 8 passes through the rotating block 3 and is fastened to the rotating block 3, the spring fixing pin 7 is fixed on the rotating bracket 5, the spring 4 is hung between the spring fixing pin 7 and the rotating block spring fixing pin 8, and the rotating bracket 5 is locked onto the lower template 6.

[0024] Example 2: Figures 1-2 As shown, there are four springs 4, which are symmetrically arranged. There are two sets of rotating block spring fixing pins 8, with two pins in each set. The top of the rotating bracket 5 has a groove at the middle, and the surface of the round tube 9 is in contact with the inner cavity of the groove. The bottom of the lower template 6 is provided with an anti-slip pad with anti-slip texture. The spring fixing pins 7 are cylindrical and symmetrical on both sides.

[0025] Working principle: The upper template 1 is locked onto the slide block of the punch press. When the slide block moves downward, it will drive the punch 2 to contact the round tube 9 first. As it continues to move downward, it will drive the rotating block 3 to rotate. When the rotating block 3 rotates, it will drive the spring 4 to stretch until the tube 9 completes the bending action. When the slide block moves upward, the rotating block 3 returns to its original position under the tension of the spring 4, thereby avoiding direct bending and effectively preventing the round tube 9 from being crushed.

[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
