Description

Pneumatic stripping machine

technical field

The utility model relates to a machine for stripping cable insulation or armor, in particular to a pneumatic stripping machine.

Background technique

The main function of the cable is to transmit signals. It is mainly composed of an outer insulating material layer, a mesh fabric shielding layer (outer conductor) and a central conductor core wire (inner conductor). In this composition structure, the outer insulating material layer can be made of polyethylene , polypropylene, polyvinyl chloride (PVC) and fluoroplastics, etc., the shielding layer is composed of metal strips or sheets that meet the transmission impedance and ECM specifications, such as mesh fabrics made of copper or aluminum, and are grounded to achieve Shielding effect.

In order to realize the transmission of signals, it is necessary to connect the core wires involving the central conductor. When connecting, the layers wrapped around the core wires need to be peeled off in turn. Due to the different materials of the core wire structures and the different depths from the core wires, currently It is generally achieved by at least two steps of manual and mechanical processes. First cut a small hole in the mesh fabric shielding layer with a wire stripper, and then peel it off by hand; finally, use a wire stripper to peel off the outer insulating material layer, so that the core wires can be exposed. Manual peeling is time-consuming and labor-intensive, and the length of peeling required is extremely difficult to precisely control.

Utility model content

The purpose of the utility model is to provide a pneumatic wire stripping machine to realize the automation of the stripping of the outer layers of the core wire, save time and effort, and improve the stripping efficiency while ensuring the precise stripping of the length of each outer layer of the chip.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a pneumatic wire stripping machine, including a frame, a knife rest assembly, a clamping assembly and a pneumatic device, wherein the knife rest assembly includes a first cutter, a second Knives and bases, the blades of the first and second knives are arranged oppositely, the first knives are fixedly installed on the base, the second knives are slidably connected to the base through a pneumatic device, and the base is connected to the frame through a pneumatic device Sliding connection; the clamping component includes a first stopper and a second stopper, the first stopper is fixedly installed on the frame, and the second stopper is slidably connected to the frame through a pneumatic device.

Preferably, the pneumatic device is provided with first and second air chambers, and a pedal controller is provided between the first air chambers, which is connected with the second cutter and the second stopper through the air duct, and the second air chamber There is a manual controller between them, which is connected with the base through an air duct.

Preferably, the wire stripping machine further includes: a positioning block, which is installed on the base through a screw assembly.

Preferably, the shape of the blade is V or U shape.

Compared with the prior art, the utility model has the following advantages:

1. Using pneumatic combined with mechanical control method, the wire is clamped and stripped first, and then the outer layer after cutting is pulled out through the sliding of the base, so that the stripping operation is completely automated, and the operation is simple and high productivity;

2. The positioning block mechanism is adopted to set the required stripping length to make the stripping length more accurate.
