Description

Technical Field

[0001] The utility model relates to the field of cold welding machines, in particular to a hand pliers type metal wire cold welding machine. Background Art

[0002] A cold welding machine, also known as a wire cold welding machine or a cold pressure welding machine, is a special welding device. The cold welding machine does not require any additives and electrical energy. Through a special mold, under a certain extrusion force, the pure metal lattices in the metal wire are pressed and combined with each other to achieve the connection principle of molecular and atomic structures, thereby welding various precious alloy wires. It is mainly used for the connection between non-ferrous metal wires and their profiles, including but not limited to metals such as aluminum, copper, nickel, gold, silver, and platinum. In the fields of optical fiber communication and optical fiber sensors, the cold welding machine is a tool for quickly connecting optical fibers, mainly used for repairing the breakpoints of optical cables, processing the tails of communication optical cables, and manufacturing optical fiber devices. Since it can quickly and accurately connect the two ends of the fiber, reducing the loss in the transmission of optical signals, it is an indispensable tool in modern communication, optical fiber sensors and other fields.

[0003] The cold welding machine can be divided into a hand pliers type cold welding machine and a table type cold welding machine. The structure of the hand pliers type cold welding machine usually includes: a cold welding drive belt, a drive copper wire opening button, a driven wheel groove frame, a through bolt, a fixed plug tube, a cold welding machine fixed ear, a cold welding machine alloy shell, a driving wheel lifting knob, a reset spring tube, and a clamping welding hand grip.

[0004] After the existing hand pliers type cold welding machine finishes welding, waste materials will remain on the side wall of the metal wire, and wire cutters need to be used separately to trim the waste materials. Therefore, the hand pliers type cold welding machine usually needs to be used in cooperation with wire cutters, which is not convenient enough. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art solutions, the utility model provides a hand pliers type metal wire cold welding machine, which can effectively solve the technical problem of inconvenient use.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Plier-type cold metal wire welding machine, including a welding body, a movable handle and a fixed handle. The surface of the welding body is provided with a die fixing groove for installing a wiring die. The movable handle and the fixed handle are both arranged at one end of the welding machine body away from the die fixing groove. The fixed handle is integrally formed with the welding body. The lower end of the welding body is provided with an adjusting screw, and the adjusting screw is perpendicular to the surface of the welding body. A cold welding transmission component is arranged inside the welding machine body. The movable handle is connected to the welding body through the cold welding transmission component. The movable handle can be flipped relative to the welding body. One end of the adjusting screw close to the welding body is mechanically connected to the cold welding transmission component. The surfaces of the welding body and the movable handle are both provided with cutting edges. The two cutting edges are parallel and in the same plane. The opposite sides of the two cutting edges can be closed to each other.

[0008] Further, one of the two cutting edges is sharpened, and the other cutting edge is not sharpened.

[0009] Further, wire inlet components are arranged on both sides of the die fixing groove. The wire inlet components include two symmetrically arranged wire clamping blocks. The wire clamping blocks are rotatably connected to the welding body. The wire clamping blocks rotate towards the die fixing groove to feed the wire. The opposite surfaces of the two wire clamping blocks are in contact with each other. The surface of the welding body is provided with an opening button for controlling the wire clamping blocks.

[0010] Further, a support column is arranged at one end of the wire clamping block away from the die fixing groove. The support column is located between the two wire clamping blocks. The top of the support column is provided with a wire rack groove, and the wire rack groove is in a "V" shape.

[0011] Further, a compression spring for resetting is arranged between the movable handle and the fixed handle.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Next, in conjunction with Figure 1 - Figure 2 a detailed description of the pliers-type metal wire cold welding machine of the present utility model will be given:

[0018] The pliers-type metal wire cold welding machine includes a welding body 1, a movable handle 2 and a fixed handle 3. A mold fixing groove 4 for installing a wiring mold is provided on the surface of the welding body 1. A fixed mounting plate 5 for fixing the wiring mold is provided at the edge of the mold fixing groove 4. The fixed mounting plate 5 is connected to the welding body 1 through a mounting nut 6. The removal and fixation of the wiring mold can be realized by adjusting the tightness of the fixed mounting plate 5. The movable handle 2 and the fixed handle 3 are both provided at one end of the welding machine body away from the mold fixing groove 4. The fixed handle 3 is integrally formed with the welding body 1. An adjusting screw 7 is provided at the lower end of the welding body 1. The adjusting screw 7 is perpendicular to the surface of the welding body 1. A cold welding transmission component is provided inside the welding body 1. The movable handle 2 is connected to the welding body 1 through the cold welding transmission component. The movable handle 2 can be flipped relative to the welding body 1. One end of the adjusting screw 7 close to the welding body 1 is mechanically connected to the cold welding transmission component.

[0019] Cutting edges 10 are provided on the surfaces of the welding body 1 and the movable handle 2. The two cutting edges 10 are parallel and in the same plane. The opposite sides of the two cutting edges 10 can be closed together. One of the two cutting edges 10 is sharpened, and the other cutting edge 10 is not sharpened. Trimming with a single edge can make the cut more flat. A compression spring for resetting is provided between the movable handle 2 and the fixed handle 3. Inlet wire components are provided on both sides of the mold fixing groove. The inlet wire components include two symmetrically arranged wire clamping blocks 8.
