Description

Technical Field

[0001] The utility model relates to the technical field of wire welding, in particular to a nylon wire shearing device inside a wire. Background Technique

[0002] When fully automatic welding and forming USB & Type-C data cables / charging cables, some wires with relatively high tensile requirements often have nylon wires inside. When these nylon wires are welded using fully automatic equipment, they have an adverse impact on automatic color separation / welding, resulting in a relatively high defective rate of the final products produced by the equipment.

[0003] Moreover, the good products welded by the equipment have nylon wires, which will affect the subsequent forming process and also need to be manually removed. This requires adding a manual shearing step, resulting in low production efficiency and increased production costs. Therefore, there are certain limitations.

[0004] Therefore, we urgently need to provide a nylon wire shearing device inside a wire. Content of the Utility Model

[0005] The purpose of the utility model is to provide a nylon wire shearing device inside a wire to solve the problem that the good products welded by the equipment have nylon wires, which will affect the subsequent forming process and also need to be manually removed. This requires adding a manual shearing step, resulting in low production efficiency and increased production costs as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a nylon wire shearing device inside a wire, including a shearing machine body and a support. The support is installed on the shearing machine body, and a nylon wire shearing device is arranged on the shearing machine body.

[0007] The nylon wire shearing device includes a wire clamping unit, a wire drawing unit, and a wire cutting unit.

[0008] The wire clamping unit includes a jaw cylinder, wire harness jaws, a moving cylinder, and a wire core support plate. The jaw cylinder is installed at the front end of the upper surface of the shearing machine body. Two wire harness jaws are respectively installed at the output ends on both sides of the jaw cylinder. The moving cylinder is installed on the top of the support. The wire core support plate is installed at the output end of the moving cylinder to guide the wire harness between the two wire harness jaws. Then, start the jaw cylinder to drive the two wire harness jaws to clamp and fix the wire harness, facilitating subsequent wire cutting. At the same time, start the moving cylinder to drive the wire core support plate to move forward to support the wire core exposed at the cutting part at the rear of the wire harness.

[0009] Further improvement lies in that the wire drawing unit includes a blowing mechanism, a blanking mechanism, and a wire drawing mechanism.

[0010] The blowing mechanism includes a tin furnace, a connecting arm, a mounting bracket, and a blower tube. The tin furnace is installed at the rear end of the upper surface of the shearing machine body. The connecting arm is installed at the front end of the tin furnace. The mounting bracket is fixedly connected to the front section of the connecting arm. The blower tube is installed on the mounting bracket.

[0011] Further improvement lies in that the blanking mechanism includes a nylon wire blanking cylinder, a static cutting knife, and a stripping block. The nylon wire blanking cylinder is installed at the front end of the shearing machine body and is located below the blower tube. The static cutting knife is installed at the top of the front surface of the nylon wire blanking cylinder. The two stripping blocks are respectively installed at the top of the outer surfaces on the left and right sides of the nylon wire blanking cylinder. When the blower tube is started to blow air downward, since the nylon wire is softer than the wire core, the nylon wire can be blown down and fall into the interior of the nylon wire blanking cylinder, thereby completing the separation of the wire core and the nylon wire and avoiding cutting the wire core.

[0012] Further improvement lies in that the wire drawing mechanism includes a nylon wire pulling-down cylinder, a nylon wire clamping cylinder, and nylon wire claws. The nylon wire pulling-down cylinder is installed at the front side of the upper surface of the shearing machine body and is located behind the nylon wire blanking cylinder. The nylon wire clamping cylinder is installed at the output end of the nylon wire pulling-down cylinder. The two nylon wire claws are symmetrically installed at the output ends on the left and right sides of the nylon wire clamping cylinder. At this time, when the nylon wire clamping cylinder is started to drive the two nylon wire claws to move relatively, the nylon wire falling into the interior of the nylon wire blanking cylinder is clamped and fixed. Then, when the nylon wire pulling-down cylinder is started to pull the clamped nylon wire downward to an appropriate position, it is convenient for subsequent wire cutting.

[0013] Further improvement lies in that the wire cutting unit includes a shearing cylinder, a connecting seat, and a cutting knife. The shearing cylinder is installed at the front end of the top of the moving cylinder. The connecting seat is installed at the output end of the shearing cylinder. The cutting knife is fixedly connected to one side of the connecting seat. When the shearing cylinder is started to push the connecting seat forward, the cutting knife on one side of the connecting seat is driven to move forward, so as to cut the nylon wire with the cutting knife, eliminating the need for manual cutting and improving the production efficiency.

[0014] Further improvement lies in that a protective cover is installed on the top of the shearing machine body. The setting of the protective cover avoids workers from accidentally touching components inside the shearing machine body such as the tin furnace, improving the production safety.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. For this wire material nylon wire shearing device, by cutting the nylon wire in the wire material before welding, the defective rate caused by nylon wire factors in wire material welding is reduced, and the total man-hour for manufacturing each wire is reduced, improving the processing efficiency.

[0017] 2. For the nylon wire shearing device inside the wire, the air cylinder blows air downward. Since the nylon wire is softer than the wire core, the nylon wire can be blown off and fall inside the nylon wire blanking cylinder, thus completing the separation of the wire core and the nylon wire and avoiding cutting the wire core.

[0018] 3. For the nylon wire shearing device inside the wire, start the nylon wire clamping cylinder to drive the two nylon wire clamping jaws to move relatively, thereby clamping and fixing the nylon wire that has fallen inside the nylon wire blanking cylinder. Then start the nylon wire pulling-down cylinder to pull the clamped nylon wire down to an appropriate position, thus avoiding the occurrence of incorrect cutting and under-cutting.

Two blanking blocks 311 are respectively installed at the tops of the outer surfaces on the left and right sides of the nylon wire blanking cylinder 309. Start the wind cylinder 308 to blow air downward. Since the nylon wire is softer than the wire core, the nylon wire can be blown down and fall into the inside of the nylon wire blanking cylinder 309, thus completing the separation of the wire core and the nylon wire and avoiding cutting the wire core.

[0033] The wire drawing mechanism includes a nylon wire downward pulling cylinder 312, a nylon wire clamping cylinder 313, and nylon wire jaws 314.
