[0002] The conventional processing method of stainless steel dental files is grinding the pyramid and axial twisting. At present, the raw materials for dental file processing are basically small-diameter steel wires. During grinding, the situations of over-grinding and warping are not significantly reflected. However, traditional small-diameter dental files cannot meet the cleaning and treatment of deeper root canals. Therefore, it is imperative to introduce large-diameter raw materials. Based on this background, the present invention aims to propose a new type of dental file forming device, which can solve the problem that when processing large-diameter raw material dental files, the tip warps and cannot be ground due to the bottom being suspended.

[0016] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. For the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Such as Figures 1-3As shown in the figure, the overall structure includes a base pedestal 6, which is fixed to the machine tool by bolts. On the base pedestal 6, there are a left vertical mounting plate 7 and a right vertical mounting plate 12. A vertical movement assembly 1 is connected to the left vertical mounting plate 7, a front-back movement assembly 8 is connected to the vertical movement assembly 1, and a thread rolling die 2 is connected to the front-back movement assembly 8 through a connecting plate 10. A wire pressing plate 5 is provided at the lower end of the thread rolling die 2. At the upper end of the right vertical mounting plate 12, there is a horizontal mounting plate 11. On the upper plane of the horizontal mounting plate 11, there is a horizontal plate 13 that contacts the lower end face of the thread rolling die 2. On the upper plane of the horizontal mounting plate 11, there is also a positioning block 4. Above the positioning block 4, there is a grinding wheel 3 mounted on the machine tool. On the upper plane of the positioning block 4, there is a groove for placing the front end wire part of the tooth thread rolling die 14. The groove includes a round wire support groove 15 for the wire and a tapered support groove 16 for the wire. The widths of the round wire support groove 15 for the wire and the tapered support groove 16 for the wire are equal to half of the circumference of the wire. The height from the left bottom plane of the round wire support groove 15 for the wire to the upper plane of the positioning block 4 is greater than the height from the right bottom plane of the round wire support groove 15 for the wire to the upper plane of the positioning block 4. The height from the left bottom plane of the tapered support groove 16 for the wire to the upper plane of the positioning block 4 is less than the height from the right bottom plane of the tapered support groove 16 for the wire to the upper plane of the positioning block 4. The height on the right side of the round wire support groove 15 for the wire and the height on the left side of the tapered support groove 16 for the wire are less than the radius of the wire.
[0018] As Figure 3 shown, in order to grind into a quadrangular pyramid shape, the widths of the round wire support groove 15 for the wire and the tapered support groove 16 for the wire are equal to half of the circumference of the wire. Two surfaces are completed on the round wire support groove 15 for the wire, and the other two surfaces are completed on the tapered support groove 16 for the wire.
[0019] The wire pressing plate 5 is connected to the upper end of a compact cylinder 9, and the compact cylinder 9 is fixed to the base pedestal 6. The wire pressing plate 5 is used for pressing and fixing during tooth file grinding. The appearance of the wire pressing plate 5 is trapezoidal, which is the same as the shape of the thread rolling die 2. A receiving cavity for the wire pressing plate 5 is provided at the lower end of the thread rolling die 2. Rubber blocks are installed at the bottom of the wire pressing plate 5. The advantage of the rubber blocks is that the wire pressing plate 5 moves up and down in the vertical direction through the compact cylinder 9 to realize the functions of wire pressing and loosening.
[0020] The thread rolling die 2 is in the shape of a right trapezoid, and its inclined surface faces the positioning block 4. The thread rolling die 2 is used for rolling and changing the surface during tooth file grinding. Rubber blocks are installed at the bottom of the thread rolling die 2. While protecting the wire from being bruised, the relatively large frictional force of the blocks ensures that there is no slipping during the surface changing of the tooth file thread rolling and grinding, and the position accuracy is high. The thread rolling die 2 moves up and down through the vertical movement assembly 1 and moves left and right through the front-back movement assembly to respectively realize the functions of wire pressing, loosening, and thread rolling surface turning.
[0021] As Figure 3As shown, the positioning block 4 is used for positioning during the grinding process of the dental file wire 14. The surface of the positioning block 4 is evenly distributed with the round wire brackets 15 and the tapered support brackets 16 of the dental tape that are closely adjacent to each other. The widths of the round wire brackets 15 and the tapered support brackets 16 of the dental tape are determined according to the diameter of the dental file wire and the number of surfaces to be ground. The round wire brackets 15 of the dental wire are used to support the circular bottom surface, and the tapered support brackets 16 of the dental tape are used to support the pyramid surface.
[0022] The specific operation process is as follows:
[0023] First step: Start the up-and-down movement component 1. The cylinder of the up-and-down movement component 1 moves upward, driving the front-and-back movement component 8 upward, lifting the wire rolling plate 2, and the compact cylinder 9 moves upward, lifting the wire pressing block 5. Place the dental wire rolling 14 to be formed on the cross plate 13. The front end of the dental wire rolling 14 is placed in the through rectangular groove of the positioning block 4, specifically on the round wire bracket 15 in the groove. The front end of the dental wire rolling 14 is aligned with the right end face of the positioning block 4. After completion, press the wire pressing block 5.
[0024] Second step: Subsequently, the grinding wheel 3 starts grinding the first surface. After the first surface is ground, the wire rolling plate 2 is pressed down, the wire pressing block 5 is lifted, and the front-and-back movement component 8 is started. The wire rolling plate 2 moves forward, causing the dental wire rolling 14 to be turned over by 90°, and continue grinding the second surface. The grinding of the first and second surfaces is completed on the round wire bracket 15 of the dental wire.
[0025] Third step: Repeat the processing of the second step until all four surfaces are ground. The grinding of the third and fourth surfaces is completed on the tapered support brackets 16 of the dental tape.
[0026] Fourth step: After the grinding is completed, the wire pressing block 5 is lifted, and the four-sided pyramid that has completed the grinding process is taken out.
[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
