The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

Fig. 1 is a schematic perspective view of a wire stripping device according to an embodiment of the present invention. As shown in fig. 1, the wire stripping device includes a holder 1, a driving portion 2, and a wire stripping portion 3.

Fig. 2 is a perspective view of a wire stripping section of the wire stripping device according to the embodiment of the present invention. Fig. 3 is a schematic diagram showing the matching of the first ram and the second ram of the wire stripping apparatus of the present invention. Figure 4 is a side view of the wire stripping apparatus of an embodiment of the present invention with the first ram mated with the second ram. As shown in fig. 2, 3 and 4, the wire stripping section 3 includes a first ram 31 and a second ram 32.

The first pressing head 31 is fixedly connected with the driving part 2, the second pressing head 32 is fixed on the bracket 1, and the first pressing head 31 is driven by the driving part 2 to move relative to the second pressing head 32. That is, the first ram 31 is driven by the driving part 2 toward the second ram 32 to be combined with the second ram 32. In the present embodiment, the driving part 2 may be, but is not limited to, an air cylinder, the first pressing head 31 is located above the second pressing head 32, and the two pressing heads have corresponding positions, and the first pressing head 31 is driven by the driving part 2 to move linearly downwards to match the second pressing head 32. Alternatively, the driving part 2 may be another part capable of driving the first ram 31 to move, or the wire stripping device may not have the driving part 2 and the first ram 31 may be manually controlled to move. In addition, the first pressing head 31 and the second pressing head 32 may have other positional relationships, the second pressing head 32 may also move toward the first pressing head 31, or both the first pressing head 31 and the second pressing head 32 are driven to move toward each other, which is not limited herein.

The first ram 31 includes a first wire groove 311, the second ram 32 includes a second wire groove 321, and the first wire groove 311 and the second wire groove 321 are formed as cavities matched with the outer diameter of the wire. That is, in the present embodiment, the first wire groove 311 and the second wire groove 321 are semicircular groove bodies with equal diameters, and can be combined to form a cylindrical cavity with a circular cross section, and the diameter of the cavity matches with the outer diameter of the wire to be processed; the first wire grooves 311 and the second wire grooves 321 can be used for fixing round wires, and in other embodiments, the first wire grooves 311 and the second wire grooves 321 are configured as continuous wavy grooves, for example, and can be applied to flat cables. Further, the first wire groove 311 and the second wire groove 321 penetrate the first indenter 31 and the second indenter 32 in the width direction of the first indenter 31 and the second indenter 32, respectively, so that the wire can pass therethrough. Alternatively, the size and shape of the first wire groove 311 and the second wire groove 321 may be set according to specific production requirements, and vary according to the outer diameter of the wire to be processed.

Further, the wire stripping blades 4 are fitted into the first wire groove 311 and the second wire groove 321, the wire stripping blades 4 of the first wire groove 311 and the wire stripping blades 4 of the second wire groove 321 correspond to each other, and the wire stripping blades 4 are arranged to cut the outer skin of the wire. That is, the wire stripping blades 4 are formed in a semicircular shape, and when the first wire groove 311 is combined with the second wire groove 321, the two wire stripping blades 4 are combined to form a ring-shaped blade, thereby being able to surround the outer skin of the cut wire. In addition, since the wire sheath to be processed has a certain thickness, the wire stripping blade 4 needs to protrude from the bottom surfaces of the first wire groove 311 and the second wire groove 321 by a predetermined distance. That is, the height of the wire stripping blade 4, that is, the portion of the wire that can effectively cut the wire, needs to be matched with the thickness of the sheath of the wire, so as to avoid contacting the core wire inside the wire and prevent the core wire from being scratched.

In the present embodiment, the first wire groove 311 and the second wire groove 321 have wire stripping blades 4 therein, which are located corresponding to each other to be able to combine to form a ring blade. The wire stripping knives 4 are provided in two sets at intervals inside the first wire groove 311 and the second wire groove 321, so that a certain section of the outer skin of the wire can be stripped during use. Alternatively, the wire stripping device may have the wire stripping knife 4 only in the first wire groove 311 or the second wire groove 321, and at this time, the wire stripping knife 4 may be rotated manually to cut the outer skin of the wire. The stripping device can also have another number of at least two stripping knives 4, for example four. And the distance that the wire stripping knife 4 is arranged in the first wire groove 311 and the second wire groove 321 at intervals can be changed, and the distance that the wire stripping knife protrudes out of the bottom surfaces of the first wire groove 311 and the second wire groove 321 can also be changed and is determined according to specific production requirements.

Further, the first ram 31 and the second ram 32 are provided with heating modules 5 inside to heat the wire stripper blades 4. That is, in order to make the wire stripping blade 4 cut the sheath of the wire rod, that is, the insulation sheath made of rubber, more easily, it is effective to increase the temperature of the wire stripping blade 4, and the first indenter 31 and the second indenter 32 may be made of a high temperature resistant material. Alternatively, the heating module 5 may be an electrical heated tube or a pulse heating assembly, or other heating assembly.

The first and second indenters 31 and 32 also have heat conducting means therein, and one end of the heat conducting means is in contact with the blade body of the wire stripping blade 4 fitted into the first and second indenters 31 and 32, and conducts heat thereto, thereby raising the temperature of the wire stripping blade 4. For example, the heat conducting device may be a metal block connected to the wire stripping blade 4 of the first wire groove 311, the wire stripping blade 4 of the second wire groove 321, and the heating module 5, and heat is transferred between the wire stripping blade 4 and the heating module 5, so that the wire stripping blade 4 is kept at a certain temperature. In addition, the temperature of the wire stripping knife 4 can be controlled by arranging other components. For example, a switch with a temperature control function is arranged in the heating module 5, and heating is stopped when the temperature is higher than a certain level, so that the wire stripping knife 4 is kept at a certain temperature, equipment overheating can be prevented, and production safety is guaranteed. Alternatively, the wire stripping device may have other forms of heat conducting devices, or other ways of controlling the temperature of the wire stripping blade 4 may be used, and the present application is not limited thereto.

Fig. 5 is a partially enlarged schematic view of a wire stripping blade of the wire stripping device according to the embodiment of the present invention. Fig. 6 is a schematic view of the tip structure of the wire stripping knife of the wire stripping device according to the embodiment of the utility model. As shown in fig. 5 and 6, in the present embodiment, the tip of the wire-stripping blade 4 has an inclined surface 41 inclined toward the inside of the wire-stripping blade 4, that is, the wire-stripping blade 4 has a shape in which the end section is approximately a right trapezoid. Alternatively, the tip of the stripping blade 4 may have other shapes, for example, as another example shown, the tip of the stripping blade 4 has two inclined surfaces 41 inclined toward the inside of the stripping blade 4, and the end portion thereof has a shape of an approximately isosceles trapezoid in cross section.

The arrangement of different shapes of the knife tip of the wire stripping knife 4 can show different cutting effects when cutting the wire sheath, for example, when the cut is approximately triangular, the cut sheath can be more easily taken down, thereby facilitating subsequent processing. The platform at the end part of the tool nose can also avoid stabbing internal core wires, thereby avoiding short circuit of the wire in subsequent processing. The shape of this application to 4 knife noses of wire stripping sword sets up does not do the restriction.

Fig. 7 is a schematic perspective view of a wire stripping portion and a carrier of a wire stripping device according to an embodiment of the present invention. As shown in fig. 7, the second ram 32 has a carrier 6 on at least one side. The carrier 6 has a wire groove 61 communicating with the second wire groove 321 in the extending direction of the second wire groove 321. That is, the wire guiding groove 61 is formed as a groove body having a semicircular cross section and a diameter equal to or slightly wider than that of the second wire groove 321, and is communicated with the second wire groove 321 to allow the wire to pass therethrough, thereby playing a role in feeding the wire, making the wire stripping apparatus easier to use, and improving the processing efficiency. In the present embodiment, the carrier 6 is formed in a shape surrounding the second ram 32 from three sides so that both sides of the second wire groove 321 have the wire groove 61 communicated therewith, alternatively, the carrier 6 may be located only on one side of the second ram 32, for example, only on the side into which the wire is fed.

Further, the second ram 32 has a base 322, and the base 322 is disposed between the second ram 32 and the cradle 1. The carrier 6 is fixed to the base 322. That is, the base 322 functions as a support for the carrier 6 and is capable of fixing the second ram 32 to the frame 1. Wherein, the heating module 5 can be disposed inside the base 322 because the base 322 has a larger space inside.
