Description
Technical Field
The invention relates to the field of orthodontic treatment, in particular to an archwire heat treatment shaping die and a manufacturing method thereof.
Background
Orthodontic appliances are increasingly being used by lovers for shaping and cosmetology, no longer just for health needs. The appliance has various types, but the appliance is a digital labial appliance or a lingual appliance, and as the optimal dental arch form and teeth of each patient are different, an individual arch wire is required to be bent according to the conditions of different patients in the correction process, so that the optimal correction effect can be achieved. The data expressed by the arch wire is important to the whole correction effect, so the bending precision of the individual arch wire is an important factor for successful correction.
The current common arch wire bending method is to bend by a skilled craftsman or bend by a mechanical arm. The manual bending has the defects of high difficulty, long time consumption and incapability of mass production. If the manipulator is used for bending, the manipulator equipment is expensive, the early investment is large, the technology is immature, the manipulator can only bend steel wires with smaller rebound quantity such as stainless steel at present, and for the arch wires with higher rebound resilience such as nickel titanium wires and beta titanium wires, the manipulator is difficult to bend accurately. In addition, the manipulator is easy to strain the arch wire in the process of bending the arch wire, so that the internal metal tissues are damaged, the arch wire is easy to break in the correction process, and the manipulator is difficult to successfully bend the arch wire with high requirements on smoothness.
Accordingly, the applicant has previously developed an archwire bending method and a die therefor, and has been issued with chinese patent application, and in particular, reference may be made to "an archwire bending method" by chinese patent application publication No. CN 109396294B. Firstly, preparing an arch wire heat treatment shaping mould, and precisely cutting an arch groove (the curvature shape of the groove is close to that of the arch wire) on a metal sheet by using a cutting machine (especially a laser cutter) according to the design shape graph or design curve data of the arch wire, wherein the arch groove is a through groove; then a lower pressing plate is placed below the metal sheet to serve as a support, the arch wire to be shaped is placed into the arch groove, another upper pressing plate is placed above the metal sheet, the upper pressing plate, the metal sheet and the lower pressing plate are fastened together, and finally the metal sheet, the metal sheet and the lower pressing plate are placed into heating equipment to be subjected to heat treatment, so that the arch wire is subjected to heat shaping in the arch groove, and the arch wire with an ideal shape is obtained.
Besides, a technical scheme is that a heat setting die is prepared by adopting a machining mode, namely, a metal plate is firstly selected, an arc-shaped groove (a non-through groove, an open top and a closed bottom of the groove) is cut on the metal plate by adopting a traditional machining mode such as cutting, milling and the like, and then an arch wire is placed into the groove for heat treatment setting. This approach does not require the use of a lower platen, but still requires the tightening of an upper platen to the metal plate.
The preparation of the two heat setting molds has common defects: (1) high material cost: whether laser cutting or machining is used, it is necessary to use a single piece of sheet metal as the blank and cut the archwire shaping slot therein. The blank of the heat treatment shaping module is usually made of a high-temperature-resistant metal material, the material cost brought by a whole metal plate is relatively high, wherein the surface area of an arch wire shaping groove occupies a small proportion of the surface area of the metal plate, the utilization rate of the blank is relatively low, and the cost is difficult to reduce; (2) large processing pollution: the metal plate is cut, so that larger dust pollution is necessarily brought in a workshop, the production cleanliness is low, and dust is easy to remain in the arched grooves; (3) the heat setting efficiency of the arch wire is low: after the archwire shaping groove is processed on the metal plate, the metal plate and the pressing plate are clamped and fixed, and the archwire shaping groove can be transferred into heat treatment equipment; every shaping one arch wire needs to be disassembled and clamped again, and the production efficiency is low.
