Description

Technical Field

[0001] The present application relates to the technical field of wire processing equipment, and in particular to a cutter structure of a sheathed wire stripping machine. Background Art

[0002] Sheathed wire is a common wire, usually composed of two, three or more cores. It can be understood as two, three or more parallel BV wires wrapped with a layer of insulating rubber. This design makes sheathed wire safer than ordinary wires because it has an extra layer of protective cover, which can reduce the risk of electric shock.

[0003] In some high-demand circuits, in order to improve the conductivity of the wire or reduce the resistance, it is necessary to strip the core wire inside the sheath wire and then perform special treatment on the core wire, such as welding, tinning, etc.;

[0004] At present, the air stripping machine usually adopts a flat knife design, that is, the upper and lower wire pressing knives of the air stripping machine are flat knives, which can only fix the core wires of the same wire diameter and then strip them. However, when it is necessary to process sheathed wires with multiple core wires of different wire diameters at the same time, the core wires of different wire diameters cannot be separated at the same time, and can only be separated by multiple operations. For example, the UL2464 2C20AWG+2C24AWG wire harness is composed of multiple groups of core wires of different wire diameters, among which the larger wire diameter is used for power transmission and the smaller wire diameter is used for signal transmission;

[0005] Therefore, it is necessary to provide a sheath wire stripping machine tool structure to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0009] Furthermore, the pressing assembly includes an upper die knife arranged above the lower die knife, a groove is provided on the upper die knife, and a dividing groove is provided inside the groove.

[0010] Furthermore, the wire stripping assembly includes a lower pressing knife arranged on one side of the lower die knife, an upper pressing knife is arranged above the lower pressing knife, and the upper pressing knife has a high and low surface.

[0011] Furthermore, a lifting assembly is installed on the branching assembly.

[0012] Furthermore, the lifting assembly includes two sets of fixed blocks installed on the lower die cutter, two sets of limit rods are installed on the fixed blocks, a top plate is commonly installed on the ends of the two sets of limit rods away from the fixed blocks, a micro motor is installed on the top plate, a screw rod is installed on the output end of the micro motor, the screw rod is rotatably installed inside the top plate and the fixed block, a moving block is threadedly installed on the screw rod, the moving block is fixedly connected to the line dividing die, and the moving block is movably arranged on the two sets of limit rods.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1 and Figure 3 As shown, the present application provides a sheath wire stripping machine tool structure, including a lower die knife 1, a wire splitting assembly 4 is fixedly installed on the lower die knife 1, and the wire splitting assembly 4 is used to strip core wires of different wire diameters. At the same time, a pressing assembly 2 is arranged above the lower die knife 1, and the pressing assembly 2 is used to fix the core wire. At the same time, a wire stripping assembly 3 is arranged on one side of the lower die knife 1, and the wire stripping assembly 3 is used to strip the core wire. Specifically:

[0025] like Figure 2-Figure 3 As shown, the wire splitting assembly 4 includes a wire splitting die 41 arranged on the lower die knife 1, and a first wire passing groove 42 and a second wire passing groove 43 are respectively opened on the wire splitting die 41, and the depth of the first wire passing groove 42 is less than the depth of the second wire passing groove 43, so as to separate the core wires of different wire diameters, and a wire splitting knife 44 is fixedly installed on the wire splitting die 41, so as to shunt the core wires of different wire diameters. When stripping the wires, the core wire with a smaller wire diameter passes through the first wire passing groove 42, and the core wire with a larger wire diameter passes through the second wire passing groove 43;

[0026] like Figure 1 and Figure 3As shown, the pressing assembly 2 includes an upper die knife 21 arranged above the lower die knife 1, and a groove 22 adapted to the wire dividing die 41 is opened on the upper die knife 21, and a wire dividing groove 23 adapted to the wire dividing knife 44 is opened inside the groove 22. The groove 22 and the wire dividing groove 23 are used for the upper die knife 21 and the lower die knife 1 to close the mold so as to resist the core wire. It should be noted that the groove 22 is divided into two sides by the wire dividing groove 23, and a height difference is formed between the two sides, so as to fix the core wires of different wire diameters;

[0027] like Figure 1 As shown, the wire stripping assembly 3 includes a lower pressing knife 32 arranged on one side of the lower die knife 1, and an upper pressing knife 31 is arranged above the lower pressing knife 32. The upper pressing knife 31 has a high and low surface to fix the core wires of different wire diameters for stripping. It should be noted that a first cylinder and a second cylinder are arranged inside the air stripping machine. The first cylinder drives the upper pressing knife 31 and the lower pressing knife 32 to clamp the core wire, and the second cylinder drives the first cylinder to move horizontally, thereby driving the upper pressing knife 31 and the lower pressing knife 32 to move, so as to strip the core wire;

[0028] In summary, when the sheathed wire is stripped, the core wire of the sheathed wire is shunted through the wire splitting assembly 4 to prevent only core wires of the same wire diameter from being processed, and then the core wire is fixed through the pressing assembly 2, and finally the core wire is stripped through the wire stripping assembly 3. It should be noted that the pressing assembly 2 is connected to the pressing power source on the air stripping machine, such as an electric cylinder, and the wire stripping assembly 3 is connected to the wire stripping power source on the air stripping machine, such as an air cylinder;

[0029] However, in the implementation process of the above patent, since the positions of the first wire groove 42 and the second wire groove 43 are fixed, when facing a core wire with a larger size, the core wire cannot pass through the first wire groove 42 and the second wire groove 43, and the wire splitting mold 41 can only be replaced, thereby increasing the workload of the staff. In order to solve this problem, a lifting assembly 5 is fixedly installed on the wire splitting assembly 4, and the lifting assembly 5 is used to lift the wire splitting assembly 4, specifically:

[0030] like Figure 2-Figure 3 As shown, the lifting assembly 5 includes two groups of fixed blocks 54 installed on the lower die knife 1, two groups of limit rods 51 are fixedly installed on the fixed blocks 54, and a top plate (not shown in the figure) is fixedly installed at one end of the two groups of limit rods 51 away from the fixed blocks 54. At the same time, a micro motor 55 is fixedly installed on the top plate, and a screw rod 53 is fixedly installed on the output end of the micro motor 55. The screw rod 53 is rotatably installed inside the top plate and the fixed block 54. At the same time, a moving block 52 is threadedly installed on the screw rod 53. At the same time, the moving block 52 is fixedly connected to the line dividing mold 41, and the moving block 52 is movably arranged on the two groups of limit rods 51;

[0031] When the position of the branching assembly 4 needs to be adjusted, the micro motor 55 is started, and the screw rod 53 drives the moving block 52 to move. At the same time, due to the action of the limiting rod 51, the moving direction of the moving block 52 is fixed. At the same time, the moving block 52 drives the branching mold 41 to move to adjust the position of the first wire groove 42 and the second wire groove 43 to facilitate the passage of core wires of different sizes.

[0032] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
