Description

Technical Field

[0001] The invention belongs to the technical field of cable processing, and in particular relates to a cable shielding net cutting device. Background Art

[0002] Cables are widely used in the fields of electrical equipment, electronic communications, new energy vehicles, etc. At present, many cables have partial shielding functions. Cables with shielding functions usually include a shielding layer surrounding the inner conductor. The shielding layer is usually composed of a braided shielding mesh, and is a tubular braided mesh formed by conductive wires. In order to install an electrical connector or a conductive terminal at the end of the cable, it is necessary to remove the outer insulation surrounding the braided shielding mesh, and then push the end of the braided shielding mesh (which covers the inner insulation) backward by a predetermined length in a direction basically perpendicular to the extension direction of the inner conductor, and at the same time widen (expand) it, and finally cut off the widened shielding braided mesh.

[0003] For example, the Chinese invention patent document with publication number CN208508217U discloses a cable shield wire brush shearing machine, which includes a clamping device, a tool assembly, a breaking device, a punching and shearing device, and a work platform. The clamping device is fixed to the work platform, the breaking device is fixed to the punching and shearing device, and the punching and shearing device is fixed to the work platform. The tool assembly includes a punching knife and a fixed knife. The punching knife is fixedly connected to the side of the breaking device close to the clamping device, and the fixed knife is fixedly connected to the clamping device. The breaking device includes a third drive device, a push plate device, a first rotating shaft, a rotating mechanism, and a brush. The third drive device is fixed to the push plate device. The first end of the first rotating shaft is rotatably connected to the push plate device. The rotating mechanism is sleeved on the second end of the first rotating shaft. The second end of the first rotating shaft is sleeved with a punching knife, and the rotating mechanism is connected to the brush. By providing the clamping device, tool assembly, breaking device, punching and shearing device, and work platform, the shielded wire can be sheared after being broken up.

[0004] For another example, the Chinese invention patent document with publication number CN217934544U discloses a cable woven shielding net device, comprising: a cable clamping mechanism, a clamping and bending mechanism, and a horizontal pushing mechanism; the cable clamping mechanism is arranged at the front end of the clamping and bending mechanism, and is used to clamp the cable extending toward the clamping and bending mechanism; the clamping and bending mechanism includes at least two clamping members, and each clamping member contracts with each other to form a clamping position, which is used to clamp the woven shielding net at the end of the cable, so that it is forced to tilt outward; when each clamping member is opened, a folding position is formed, and the horizontal pushing mechanism pushes the cable clamping mechanism or the clamping and bending mechanism, so that the folding position pushes the tilted woven shielding net to fold in the opposite direction. The folding mechanism includes a side plate, a guide, a movable seat, an electric screw assembly, a sleeve and a rotating motor. The guide is arranged between the clamping and bending mechanism and the side plate. The movable seat is slidably connected to the guide. The electric screw assembly is connected to the movable seat to drive the movable seat to move along the guide. One end of the sleeve is rotatably connected to the movable seat. The rotating motor is arranged on the movable seat and connected to the sleeve to drive the sleeve to rotate. The other end of the sleeve is provided with an inner hole, and the end of the sleeve forms an annular cutting edge. An extrusion cutter is provided on the back of the clamping member, and the extrusion cutter and the annular cutting edge of the sleeve extrude the folded woven shielding mesh.

[0005] The technical solutions disclosed in the above-mentioned patent documents are to first expand the shielding braided mesh and then use the punching method to complete the punching along the root position of the bend of the turned-out shielding braided mesh. In order to complete the turning-out of the shielding braided mesh, whether it is broken up by a brush or by clamping, a certain amount of processing time is required. After breaking it up, it is punched out, and punching again requires a certain amount of time. As a result, the processing time of cutting the shielding braided mesh cannot adapt to the current automated production rhythm. It is necessary to separate the turning-out and cutting of the shielding braided mesh into two processes to reduce the working time of a single process to meet the production rhythm of the automated equipment. Due to the turning-out of the shielding braided mesh, the diameter of the turned-out part is large, so it cannot be punched through the punching die or the punching hole of other punching structures.

[0033] In one embodiment of the cable shielding net cutting device of the present invention, the cable shielding net cutting device includes a cable shielding net cutting device and a conveyor line. The cable shielding net cutting device can be set in the next process of the shielding net turning process. The conveyor line is provided with a plurality of wire clamps for clamping cables. Specifically, the wire clamps on the conveyor line clamp the shielding net and pass through the shielding net turning process to complete the shielding net breaking and turning outside, and then convey it to the cable shielding net cutting device, and the cable shielding net cutting device completes the punching process of the shielding net.

[0034] Reference Figures 1 to 4 The cable shielding net cutting device includes a mounting frame 100, a first punching mechanism 200, a second punching mechanism 300 and a driving mechanism 400. The mounting frame 100 includes a template 110, which is provided with an air-avoiding through-hole 111. A first punching hole 112 and a second punching hole 113 are respectively provided on both sides of the air-avoiding through-hole 111. A channel 114 is provided between the first punching hole 112 and the second punching hole 113 and the air-avoiding through-hole 111. The cable inserted into the air-avoiding through-hole 111 can move to the first punching hole 112 and the second punching hole 113 through the corresponding channel 114. The aperture of the air-avoiding through-hole 111 is larger than the aperture of the first punching hole 112 and the second punching hole 113. Among them, the aperture size of the air-avoiding through-hole 111 is determined by the length of the shielding braid of the cable, while the aperture size of the first punching hole 112 and the second punching hole 113 is determined by the diameter of the cable.

[0035] The first and second punching mechanisms 200 and 300 are located inside the mounting frame 100. The first punching mechanism 200 includes a first punching blade 210 that engages with the first punching hole 112. The second punching mechanism 300 includes a second punching blade 310 that engages with the second punching hole 113. The first and second punching blades 210 and 310 are connected to a drive mechanism 400. The drive mechanism 100 drives the cable clamp or mounting frame to move the cable between the first and second punching holes.

[0036] In this embodiment, a wire clamp holds the cable with the braided shield mesh turned outward and moves it to one side of the cable shield mesh cutting device. The cable passes through the air-proof through-hole 111 of the template 110, and the outward-turned shield mesh passes through the air-proof through-hole 111 together, and the outward-turned shield mesh is located on the inside of the template 110. The mounting frame 100 or the cable is moved so that the cable passes through the channel 114 and is transferred to the first punching hole 112. The driving mechanism 300 drives the first punching knife 210. The first punching knife 210 cooperates with the first punching hole 112 to complete the punching of more than half of the shield mesh. The cable is then transferred to the second punching hole 113. The driving mechanism 300 drives the second punching knife 310. The second punching knife 310 cooperates with the second punching hole 113 to complete the punching of the remaining braid mesh. Therefore, this cable shield mesh cutting device can realize the cable braiding and braiding cutting as two independent processes, and can be applied to current automated production lines to meet actual production needs.

[0037] Furthermore, a preferred embodiment of the cable shielding mesh cutting device is described in detail with reference to Figure 1 and Figure 2, also includes a moving mechanism 500, and the moving mechanism 500 is arranged on a body 600.

The first punching hole 112, the second punching hole 113 and the air-avoiding through hole 111 are in the same straight line and parallel to the moving direction of the mobile end. Preferably, the moving mechanism drives the mounting bracket to move up and down. Specifically, in this embodiment, after the outward-turned end of the shielding braided mesh of the cable passes through the air-avoiding through hole 111, the moving mechanism 500 drives the mounting bracket 100 to rise, and the cable enters the first punching hole 112 from the channel 114 at the lower end of the channel air-avoiding through hole 111, and the first punching knife 210 cooperates with the first punching hole 112 to complete the punching of the shielding braided mesh of the lower half of the cable. The moving mechanism 500 then drives the mounting frame 100 downward, transferring the material within the first punching hole 112 to the second punching hole 113. The second punching blade 310 cooperates with the second punching hole 113 to complete the punching of the shielding braided mesh on the upper half of the cable. Furthermore, punching the shielding braided mesh on the lower half of the cable before punching the upper half can prevent any material from being lost during punching of the upper half from affecting the punching of the shielding braided mesh on the lower half. The moving mechanism 400 can be a motorized linear module or a linear module.
