Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-5, an orthodontic pliers with stable use of a tool bit comprises a stainless steel pliers body, wherein the pliers body comprises a left handle 1 and a right handle 2, one side of the left handle 1 and one side of the right handle 2 are integrally formed with a pliers head 3 which can work in a mutually matched mode, a tool bit assembly 4 is welded on the pliers head 3, the tool bit assembly 4 comprises a tool bit part 401 and a connecting part 402, one end of the connecting part 402 is connected to the tool bit part 401, and the other end of the connecting part is connected to the pliers head 3.
According to actual requirements, the cutter head portion 401 and the connecting portion 402 can be integrally formed, and can also be in a welding type connection mode or other connection modes, the connecting portion 402 and the caliper head 3 can be in plane and plane direct welding, and can also be in plane embedded connection in a groove or other clamping modes, and only the connecting portion 401 needs to be designed within a certain thickness range, so that a certain distance is formed between the cutter head portion 401 and the caliper head 3. During the preparation, earlier form stainless steel pincers body through mould integrated into one piece, then get the good tool bit subassembly of processing, with the connecting portion 402 of tool bit subassembly weld in the corresponding position of binding clip 3 can.
The utility model discloses a pliers, moreover, the steam generator is simple in structure, through set up connecting portion 402 on the tool bit, make connecting portion 402 and binding clip 3 welding, certain interval has been formed between messenger's tool bit portion 401 and the binding clip 3, that is to say, in the welding process of processing tool bit subassembly and binding clip 3, the change of tool bit portion 401 material because of high temperature welding arouses has been avoided widely, thereby lead to it to produce annealing, bad reaction such as fragility increases, guarantee the performance of tool bit portion 401 itself, and simultaneously, in the use of pliers, the effort that the tool bit produced can not directly influence the welding fastness between connecting portion 402 and the binding clip 3 yet, the fracture of tool bit has effectively been prevented, the scheduling problem drops, the connection fastness stability and the stability in use of tool bit have been strengthened, thereby the holistic validity of pliers and life have been improved.
Furthermore, the other end of the connecting portion 402 is further provided with a welding portion 403, the binding clip 3 is provided with an installation groove 301, the welding portion 403 is welded in the installation groove 301, a first filling groove 5 is formed between the welding portion 403 and the binding clip 3, and the first filling groove 5 is filled with stainless steel wires, so that a complete connecting plane is formed between the welding portion 403 and the binding clip 3. Above-mentioned design makes things convenient for the welding operation of weld part 403 and binding clip 3, through the packing of stainless steel wire, has carried out the fastness once more to weld part 403 and binding clip 3 and has consolidated, has improved welding fastness between them and has improved subsequent use fastness stability to improve the holistic stability in use of pliers, the concrete processing mode is: earlier form the stainless steel pliers body through mould integrated into one piece, get the good tool bit subassembly of processing again, weld part 403 primary weld of tool bit subassembly in mounting groove 301, and form first filling groove 5, then get a stainless steel wire, aim at the position of first filling groove 5 with the stainless steel wire, stainless steel wire is dissolved to rethread laser-beam welding machine, make stainless steel wire build-up welding fill in first filling groove 5, treat that the stainless steel wire dissolves completely the back, utilize cutting or mill processing to grind the notch edge in first filling groove 5 and flatten, make form complete connection plane between weld part 403 and binding clip 3.
Further, a second filling groove 6 is formed between the connecting portion 402 and the binding clip 3, and a stainless steel wire is filled in the second filling groove 6, so that a complete connecting plane is formed between the connecting portion 402 and the binding clip 3. Above-mentioned design, the packing welding that has formed the stainless steel wire in four sides between messenger's tool bit subassembly 4 and the binding clip 3, the fastness of being connected between tool bit subassembly 4 and the binding clip 3 has been improved greatly, can prevent effectively that the tool bit from breaking or the scheduling problem that drops from appearing, thereby guarantee the use validity and the life of pliers, the mode that the stainless steel wire was filled in 6 intussuseptions of second filling groove is the same with the mode that the stainless steel wire was filled in 5 first filling grooves, make at last to form complete connection plane between connecting portion 402 and the binding clip 3, still can improve the whole aesthetic property of pliers.
Further, one side wall of the mounting groove 301 is a vertical surface, the other side wall is an inclined surface, the welding portion 403 corresponds to the shape of the mounting groove 301, a first arc-shaped transition surface 302 is formed between the bottom end of each of the vertical surface and the inclined surface and the bottom wall of the mounting groove 301, and a second arc-shaped transition surface 404 is correspondingly formed at the bottom end of the welding portion 403. Due to the design, the welding part 403 and the mounting groove 301 can be better welded in a positioning mode, the welding precision and the welding fastness of the welding part 403 and the mounting groove are improved, and the use stability of the pliers is improved.
Further, the cutter head component 4 is made of white steel which is integrally formed, and a vertical transition connection or an arc transition connection is formed between the connecting portion 402 and the cutter head portion 401. According to the design, the bonding force between the white steel and the stainless steel is good, so that the inlaying fastness of the white steel and the stainless steel pliers head and the welding fastness of the white steel and the stainless steel wire are stable, and the connection fastness of the cutter head assembly 4 and the pliers head 3 is more stable; moreover, the color of the white steel is similar to that of the stainless steel, bonding traces of the white steel and the stainless steel are not obvious, the carbon content of the white steel is high, high hardness can be guaranteed, high corrosion resistance can be guaranteed after special alloy is added, and the white steel is not easy to rust, so that the bonding position is not easy to rust after the two materials are bonded, and the overall quality of the pliers is good.
Further, the thickness of the connecting portion 402 is 8-16 mm. The connecting portion 402 within the above thickness range can protect the cutter head portion 401, so that the subsequent use performance thereof is more stable, because if it is too thin, the hardness change of the cutter head portion 401 is affected during welding; meanwhile, the overall use effect of the pliers can be ensured, because if the connecting part 402 is too thick, the handle has larger elasticity, so that the cutting is not smooth.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
