Description
Technical Field
The present invention relates to a die plate structure, and more particularly to a die plate structure for forming a 6-4 titanium alloy screw.
Background
The existing screw is mostly made of iron materials through cold forging, and the structure of the existing screw is made of the iron materials, so the existing screw has poor strength, poor corrosion resistance and easy oxidation and rust, after the existing screw is driven by a hand tool for a long time, each end angle of the screw hole has a deformation phenomenon of abrasion due to torsion generated during rotation, the integrity of the screw hole is damaged, and therefore, the problem of slippage generated during the driving of the hand tool is caused, and the screw cannot be used.
Further, a titanium alloy is a metal material having excellent mechanical properties and has been widely used in various industrial fields in recent years, but when a titanium alloy is used for manufacturing a screw, the titanium alloy has the following difficulty in processing due to its unique material properties; for example:
1. titanium alloy heat conductivity is poor, and the high temperature that produces during the processing is difficult for effectively transmitting to the cutter outside, makes the heat gather on the processing cutting edge in a large number, and the red hardness that can make the cutting edge after the temperature sharply rises descends, causes the cutting edge to soften, and then the wearing and tearing of cutter are accelerated.
2. The titanium alloy has high affinity, the phenomenon of serious knife adhesion is easily generated during processing, the friction between the cutting edge and a workpiece is increased, the high temperature is caused, and the service life of the cutter is further shortened.
3. The titanium alloy has small elastic modulus, and is easy to generate larger deformation, rebound, distortion and vibration in cutting, so that the error value of the processing shape and the precision of a workpiece is increased, and the surface roughness is increased; therefore, titanium alloys are classified as mechanical materials that are not easily processed.
According to the examination, the tensile strength of the titanium alloy material before processing is above 895MPa, and the yield strength is above 828 MPa. Because of the special strength and property of titanium alloy, if the titanium alloy is processed into screw by thread rolling deformation, the material is easy to break and scrap, and the tooth-shaped tissue of the thread rolling will generate fracture surface or fish scale. The titanium alloy material is opposite to the general metal manufacturing flow, and is difficult to process due to the prior strength reshaping, which is also a main reason that mass production cannot be realized. At present, titanium alloy screws with acceptable quality in the industry can be produced only by turning with a CNC lathe, and the screw is produced in a thread turning manner, so that the production value is slow, the time cost is high, the selling price of the screw is naturally high, and the manufacturing of the titanium alloy screw is still greatly limited. Therefore, the screws currently available on the market cannot meet the high-level requirements, and mass-produced titanium alloy screws are not available on the market for consumers to choose from, which is very unfortunate.
In view of the above, the present inventors have found that, in order to solve the problem that the high-level screw cannot be mass-produced in the market, through research and development and manufacturing experience of related industries for many years, and through continuous research and trial, a dental plate structure is developed, thereby overcoming the above-mentioned problems.

In order to make the technical content, purpose and efficacy achieved by the present invention more completely and clearly disclosed, the present invention will now be described with reference to the accompanying drawings:
first, please refer to a three-dimensional structural view of the embodiment shown in fig. 1 and a plan structural view of the embodiment shown in fig. 2.
The dental plate structure of the utility model comprises two corresponding dental plate bodies 10. The two tooth plate bodies 10 are made of metal material with Rockwell Hardness (HRC) above 67, and after surface treatment, the Rockwell Hardness (HRC) of the two tooth plate bodies 10 surface should preferably reach 70.
One end surface of the two tooth plate bodies 10 is a thread rolling surface 11, the thread rolling surface 11 is provided with a plurality of thread grooves 12 which are obliquely arranged at intervals and are used for rolling the shape of a thread, and each corner end of the thread groove 12 is an arc-shaped turning part 121 (as shown in fig. 4) which is in an arc shape; the rolling surface 11 is divided into a plurality of forming areas and a finishing area 16, in this embodiment, the plurality of forming areas are described by a first forming area 13, a second forming area 14, and a third forming area 15 (refer to fig. 1, fig. 2, and fig. 3).
The surface of the first forming region 13 forms a first rough surface 131, the surface of the second forming region 14 forms a second rough surface 141, the surface of the third forming region 15 forms a third rough surface 151, and the surface of the finishing region 16, except for the tooth grooves 12, is a flat surface 161; the first rough surface 131 has the largest surface roughness value, the second rough surface 141 has the second smallest surface roughness value, and the third rough surface 151 has the smaller surface roughness value; the first rough surface 131, the second rough surface 141, and the third rough surface 151 are formed by a plurality of fine grooves 1311, grooves 1411, and grooves 1511 (see fig. 4). There is a height difference between the first forming area 13, the second forming area 14, the third forming area 15 and the finishing area 16 of the rolling surface 11, such as a step-like relationship as shown in fig. 3, or a slant relationship as shown in fig. 5, wherein the first forming area 13 is lowest, the second forming area 14 times, the third forming area 15 is higher, and the finishing area 16 is highest; however, the step difference is an extremely small size, and the drop height between each adjacent molding regions is about 0.01 mm to 0.05 mm, but not limited thereto (as shown in fig. 3).
