Technical Field
[0001] The utility model belongs to the technical field of wire cutting, and in particular relates to a wire cutting profile small-aperture molybdenum wire threading tool. Background Art
[0002] Wire cutting is a processing method that uses a moving molybdenum wire as an electrode wire, and relies on pulsed electric spark discharge between the electrode wire and the workpiece to generate high temperature to melt or vaporize the metal, forming a slit, and thus cutting out parts. When threading molybdenum wire through small-sized processes on profiles, especially when punching holes from the bottom of the profile upward, not only is it difficult for the guide molybdenum wire to align and penetrate the process hole on the profile because of its small size, but it is also difficult for the operator to observe the position of the process hole when threading from the bottom of the profile upward, resulting in difficulty in threading molybdenum wire. Summary of the invention
[0003] The technical problem to be solved by the utility model is to improve an auxiliary tooling which is convenient for threading molybdenum wires through small-size process holes of iron profiles from bottom to top.
[0004] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: a wire cutting profile small-diameter molybdenum wire threading tool, including a guide pin, a gasket, a first traction ring, a first split tool, a second split tool and a first permanent magnet, the gasket is fixedly sleeved and installed on the top of the guide pin, the first traction ring is fixedly installed on the gasket, the first split tool is provided with a positioning hole, the second split tool is fixedly provided with a positioning pin, the first split tool and the second split tool are buckled and fixed to form a tool body, and the positioning pin is embedded and installed in the positioning hole. In the positioning hole, second permanent magnets that attract each other are fixedly embedded on the contact surfaces of the first split tooling and the second split tooling, a wire threading channel is formed at the center of the tooling body, the bottom of the wire threading channel is set as a wide-mouth structure, and the top of the wire threading channel is set as a lock-shaped structure. The first split tooling and the second split tooling are both provided with bayonet holes on the outer sides of the tops, and the first permanent magnet is fixedly embedded in the bayonet holes on the outer sides of the tops of the first split tooling and the second split tooling, and the top surface of the first permanent magnet is flush with the top surfaces of the first split tooling and the second split tooling.
[0005] Preferably, the second permanent magnet is fixedly arranged at an edge position of a contact surface between the first split tooling and the second split tooling.
[0006] Preferably, anti-skid rubber pads are fixedly attached to the outer walls of the first split tooling and the second split tooling.
[0007] Preferably, a second traction ring is fixedly provided on the first split tooling and the second split tooling.
[0008] Compared with the prior art, the advantages of the utility model are: the device can be applied to the molybdenum wire threading operation from bottom to top at the bottom of the small-sized process hole of iron profiles, and the guide needle made of hard material that is not easy to bend and deform can quickly and accurately position the tooling body, which has the advantages of simple operation and high molybdenum wire threading efficiency. The first permanent magnet is attracted and fixed, which has the advantages of fast positioning speed and firm fixation, and is convenient for moving and adjusting the tooling body.

[0012] The utility model is described in detail below in conjunction with specific implementation methods:
[0013] like Figure 1 and Figure 2 The wire cutting profile small-diameter molybdenum wire threading tool shown in the figure comprises a guide pin 1, a gasket ring 2, a first traction ring 3, a first split tool 4, a second split tool 5 and a first permanent magnet 6, wherein the gasket ring 2 is fixedly sleeved and installed on the top of the guide pin 1, the first traction ring 3 is fixedly installed on the gasket ring 2, the first split tool 4 is provided with a positioning hole 41, the second split tool 5 is fixedly provided with a positioning pin 51, the first split tool 4 and the second split tool 5 are buckled and fixed to form a tool body, the positioning pin 51 is embedded and installed in the positioning hole 41, and the first split tool The contact surfaces of the first split tooling 4 and the second split tooling 5 are fixedly embedded with second permanent magnets that attract each other, a wire threading channel 40 is formed at the center of the tooling body, the bottom of the wire threading channel 40 is set as a wide-mouth structure, and the top of the wire threading channel 40 is set as a lock-like structure 411, and the outer sides of the tops of the first split tooling 4 and the second split tooling 5 are both provided with bayonet sockets, and the first permanent magnet 6 is fixedly embedded in the bayonet sockets on the outer sides of the tops of the first split tooling 4 and the second split tooling 5, and the top surface of the first permanent magnet 6 is flush with the top surfaces of the first split tooling 4 and the second split tooling 5.
[0014] The second permanent magnet is fixedly disposed at the edge of the contact surface between the first split tooling 4 and the second split tooling 5 to avoid magnetic influence on the molybdenum wire 9 at the center.
[0015] The outer walls of the first split tool 4 and the second split tool 5 are fixedly provided with anti-skid rubber pads 7 , and the anti-skid rubber pads 7 increase the friction force, making it easier for operators to perform hand-held operation on the tool body.
[0016] The first split tooling 4 and the second split tooling 5 are fixedly provided with second traction rings 8 , and the first split tooling 4 and the second split tooling 5 can be pulled and separated after being sucked and fixed by the two second traction rings 8 .
[0017] The guide needle 1 is made of a hard material that is not easy to bend and deform. When the molybdenum wire 9 is threaded upward from the lower part of the profile 10, the guide needle 1 is inserted into the process hole 101 formed 10, and the gasket ring 2 is placed on the top of the profile 10. First, the first split tooling 4 is positioned with the guide needle 1 and then fixed with the iron profile 10 by the first permanent magnet 6. Then the second split tooling 5 is fixedly installed on the tooling body of the first split tooling 4. The first permanent magnet 6 on the second split tooling 5 is fixed with the iron profile 10. The operator pushes and pulls the guide needle 1 up and down to determine whether it is in contact with the threading channel 40. It is in a coaxial state. If it is not in a coaxial state, the operator adjusts the position of the tooling body. If it is in a coaxial state, the guide needle 1 is pulled outward through the first traction ring 3, and the molybdenum wire 9 is inserted from the wide-mouth structure set at the bottom of the wire threading channel 40. Since the top of the wire threading channel 40 is set as a lock-shaped structure 411, even if the wire threading channel 40 and the process hole 101 are slightly offset, it will not cause any obstruction to the molybdenum wire 9. The molybdenum wire 9 can be easily inserted into the process hole 101 of the profile 10, and then the first split tooling 4 tooling body and the second split tooling 5 can be separated and removed.
