Description

Technical Field

[0001] This utility model relates to the technical field of hardware bending devices, and in particular to a star-shaped decorative structure quick bending device. Background Technology

[0002] Fences are widely used in factories to demarcate exclusive areas, isolate them from the outside world, prevent unauthorized personnel from entering, and protect the property within the area. Currently, common fences are constructed by welding and assembling horizontal bars, vertical bars, and decorative patterns. From a geometric perspective, the pentagram is the polygon with the fewest sides and is one of the simplest and most perfect geometric patterns. Therefore, the pentagram is often used as a decorative pattern for fences.

[0003] Due to its age, the fence was partially rusted and peeling. While maintenance workers could easily find suitable replacements for the horizontal and vertical bars, they struggled to locate the five-pointed star decorative pattern. Consequently, the repaired fence did not match the original, affecting its aesthetics.

[0004] Therefore, there is an urgent need for a rapid bending device for star-shaped decorative structures. Utility Model Content

[0025] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: As Figures 1-3 As shown, a star-shaped decorative structure quick bending device includes a base 1, a module 2, and a pressure head 3. The module 2 is connected to the base 1 and includes an isosceles triangular part 201 connected to an isosceles trapezoidal part 202, with two included angles a between the isosceles triangular part 201 and the isosceles trapezoidal part 202. A rocker arm 305 is connected to the pressure head 3 and is rotatably connected to the base 1. One end of the pressure head 3 is conical and can fit and engage with one included angle a of the module 2. A backing plate 4 is welded to the base 1. The backing plate 4 is parallel to one side of the isosceles triangular part 201, and a groove 5 is formed between the backing plate 4 and the isosceles triangular part 201.

[0027] Module 2 is made of stainless steel and is connected to the stainless steel base 1 by screws. The isosceles triangle part 201 is located at the center of the lower base of the isosceles trapezoid part 202, and the isosceles triangle part 201 and the isosceles trapezoid part 202 are integrally formed.

[0028] The included angle α formed between the isosceles triangular portion 201 and the isosceles trapezoidal portion 202 is 108°, the included angle b of the isosceles triangular portion 201 is 36°, and the included angle c at one end of the isosceles trapezoidal portion 202 is 36°.

[0029] A fixing pin 6 is connected to the base 1 on one side of the plate 4, and a circular sleeve 301 is connected to one end of the rocker arm 305. The circular sleeve 301 is rotatably connected to the outer circular surface of the fixing pin 6.

[0030] The pressure head 3 is made of stainless steel. A handle 302 is connected to one side of the pressure head 3. An anti-slip sleeve 303 is connected to one end of the handle 302. A limit stop bar 304 is connected to the bottom of the handle 302.

[0031] The base 1 is disc-shaped and has several mounting holes 101.

[0032] Example 2: This example is a further improvement on Example 1. The main improvement is that Example 1 could not determine whether the shape was regular after bending and forming; while in this example, the above-mentioned defect can be avoided. Specifically:

[0033] The base 1 has a five-pointed star-shaped groove 102, and the module 2 is fitted into the inner contour of the groove 102. In this embodiment, the base 1 has a five-pointed star-shaped groove 102, which serves as a comparison. After the five-pointed star is bent, it can be picked up and placed on it to compare whether the bending at each angle is correct.

[0034] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0035] The specific working principle of this utility model is as follows:

[0036] Before actual use, install the tool on the workbench through the mounting hole 101; during actual work, first calculate the length of the iron bar / sheet.

[0037] Adjust the pressure head 3 to its maximum position.

[0038] Then insert one end of the iron strip / sheet to be bent into slot 5.

[0039] Hold the 302 handle and turn it clockwise to slowly bend the iron bar / sheet.

[0040] After folding one corner, pick it up and place it in slot 5, then fold the other corner. Repeat this process five times to complete the metal frame for a five-pointed star.

[0041] Next, place it into the five-pointed star-shaped groove 102 for comparison. Check if the angles are suitable, and then make slight adjustments by pressing and folding.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
