Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pneumatic wire stripping, in particular to a pneumatic wire stripping device. BACKGROUND

[0002] In the use of cables, the insulating layer on the outside needs to be stripped, at which time a wire stripping machine will be used, and its principle is to cut off and pull down the insulating layer of the cable, thereby playing a role in stripping the wire. At present, the common wire stripping machines on the market are mostly electrically controlled wire stripping machines: electric elements are used for control, and cylinder elements are used for power. The electrically controlled wire stripping machine needs to be connected to both power supply and air source at the same time when in use, which not only puts forward certain requirements for the use scene, but also increases the maintenance cost, and brings safety hazards; in addition, the traditional wire stripping machine is also prone to accumulate waste, which needs to be cleaned manually, thereby increasing the workload.

[0003] A pneumatic wire stripping device known to the inventor (patent document number CN221150781U) is started and stopped through an electromagnetic valve switch control device, the bottom is provided with a sleeve connecting rod which is constantly lowered to drive the contact roller and the movable frame to extrude and move backward, so as to move the lower blade backward; because the upper end of the moving frame is connected with a telescopic rod, and the other end of the telescopic rod is connected with the moving plate, the upper blade also moves backward due to the movement. This can complete the process of synchronously moving the upper and lower blades backward to separate the cut insulating skin from the core wire, and the cut insulating skin is pushed by the moving frame and falls into the collection frame when reaching the discharge chute, thereby realizing automatic collection.

[0004] However, the inventor of the present application found at least the following technical problems in the process of implementing the technical solutions of the embodiments of the present application:

[0005] Firstly, the device is controlled to start and stop by an electromagnetic valve, and is not fully pneumatic, the addition of electric elements will increase the maintenance cost and cause safety hazards; in addition, the insulating skin collection frame of the device is located directly below the device, and there is almost no space below the device, so that the volume of the insulating skin collection frame of the device is too small and needs to be cleaned frequently, which cannot effectively solve the problem of waste accumulation.

[0026] Unless otherwise specified, the unit modules or sensors involved in the following embodiments are all commercially available products.

[0027] This application provides a pneumatic wire stripping device that solves the problem that the use of electrical control components in the prior art increases maintenance costs and safety hazards. By employing a foot switch and a pneumatic wire stripping machine in the pneumatic wire stripping device, the idea of ​​using only pneumatic power throughout the entire production process can be realized.

[0028] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0029] The air supply unit provides the device with impurity-free air at a specified pressure. The air supply is controlled by a foot switch connected to an air supply tube. When the foot switch is turned on, the treated air is delivered to the wire stripper assembly, so that the wire stripper works in the sequence of pressing, cutting and stripping the wire. Another air tube runs from the foot switch to the lower part of the wire stripper assembly, and blows the waste into the waste collection box by blowing air, thus completing the entire production process.

[0030] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0031] This example discloses a pneumatic wire stripping device; see [link to relevant documentation]. Figure 1 Specifically, it includes 1-1 the wire stripper assembly and 1-2 the air source triplet, which are fixed to the 1-3 workbench by screws to maintain the overall stability of the device. 1-4 The foot switch is placed naturally on the ground and connected to the 1-1 wire stripper assembly and 1-2 air source triplet via the 1-7 air pipe for on / off control. 1-5 The waste discharge channel is fixed to the 1-1 wire stripper assembly by screws for waste discharge. 1-6 The waste collection box is placed freely below the discharge port of the 1-5 waste discharge channel, without connection or fixation to other components, for waste collection.

[0032] See Figure 2 The 1-2 air source triplet includes the 2-1 cylinder assembly, the 2-2 pressure reducing valve, and the 2-3 oil mist lubricator. The 2-1 air filter and the 2-3 oil mist lubricator are installed on the left and right ends of the 2-2 pressure reducing valve by threaded connection, together forming the 1-2 air source triplet, which is used to filter oil mist, water vapor and other impurities in the air source and adjust the air pressure to the specified value.

[0033] See Figure 3 The 1-1 wire stripper assembly includes the 3-1 cylinder assembly and the 3-2 mechanism assembly, which are assembled together by screw connection and together constitute the 1-1 wire stripper assembly.

[0034] See Figure 4 The cylinder assembly structure consists of three cylinders: 4-1 (wire clamping cylinder), 4-9 (wire cutting cylinder), and 4-13 (wire stripping cylinder), which are mounted on the 4-2 cylinder mounting plate via screws and function as power components. The 4-2 cylinder mounting plate has a C-shaped structure; its bottom surface is threaded onto the 4-7 base, while its upper surface and sides provide mounting positions for the 4-1 wire clamping cylinder, 4-9 wire cutting cylinder, 4-13 wire stripping cylinder, and 4-11 baffle. The 4-3 upper pressure block mounting plate is threaded onto the 4-1 wire clamping cylinder shaft, providing a mounting position for the 4-4 upper pressure block. The 4-4 upper pressure block is screwed onto the 4-3 upper pressure block mounting plate and connected to the 4-14 upper slide rail via a fixed slideway, forming a linear sliding fit. This connection is used to complete the pressing and resetting motion of the fixed rail under the drive of the 4-1 wire clamping cylinder. The 4-16 lower slide rail is fixed to the 4-7 base with screws. It has a fixed slide rail and connects with the 5-6 lower slide block to form a linear sliding fit. The 4-5 air pipe fixing block is fixed to the 4-16 lower slide rail with screws and is used to install the 1-7 air pipe and adjust its position. The 4-6 lower pressure block is fixed to the 4-16 lower slide rail with screws and works with the 4-4 upper pressure block to complete the wire clamping action. The 4-7 base is fixed to the 4-16 lower slide rail with screws, providing support for all components. The 4-8 fine-tuning nut is installed and fixed to the back of the 4-1 wire clamping cylinder, 4-9 wire cutting cylinder, and 4-13 wire stripping cylinder with threads, used for fine-tuning the cylinder stroke distance. The 4-10 pneumatic connector is assembled to the 4-1 wire clamping cylinder and 4-9 wire cutting cylinder with threads, used for connecting to the 1-7 air pipe for air supply. 4-11 The baffle is fixed to the 4-2 cylinder mounting plate by screws for side enclosure. 4-12 The speed control valve is threaded onto the 4-13 wire stripping cylinder for adjusting the cylinder's extension and retraction speed. 4-14 The upper slide rail is threaded onto the 4-9 tangent cylinder shaft for pressing and resetting under the drive of the 4-9 tangent cylinder. The front end of the 4-14 upper slide rail also features a vertical groove slide, connecting with the 4-4 upper pressure block and the 5-1 upper slider to form a linear sliding fit. 4-15 The cylinder adapter is threaded onto the 4-13 wire stripping cylinder shaft at one end, and connected to the 5-6 lower slider via a keyway at the other end. A certain gap is designed at the keyway connection to provide cushioning between the 4-13 wire stripping cylinder and the 5-6 lower slider.

[0035] See Figure 5The mechanism assembly structure and connection method are as follows: the upper slider (5-1) and the lower slider (5-6) are connected via the guide shaft (5-7) to ensure the accuracy of the upper and lower pressing positions of the device. The upper cutter (5-3) is protected on both sides by the shims (5-2) and is fixed to the upper slider (5-1) with screws. The lower cutter (5-4) is also protected on both sides by the shims (5-2) and is fixed to the lower slider (5-6) with screws. The stop block (5-5) is fixed to the lower slider (5-6) with screws and is used to adjust the wiring harness positioning.

[0036] During operation, the 1-2 air source triplet first filters and regulates the pressurized gas. The operator presses the 1-4 pneumatic foot switch, causing pressurized gas to flow into each cylinder, simultaneously engaging the 4-1 wire clamping cylinder, the 4-9 wire cutting cylinder, and the 4-13 wire stripping cylinder. When the 4-1 wire clamping cylinder moves, it drives the 4-4 upper pressure block downwards via the 4-3 upper pressure block fixing plate connected in the middle. This, together with the 4-6 lower pressure block fixed in front of the 4-16 lower slide rail, clamps the wire harness, preventing it from shifting. When the 4-9 cutting cylinder moves, it drives the 5-1 upper slider, 5-3 upper cutter and other parts to press down through the 4-14 upper slide rail connected in the middle. The 5-3 upper cutter and the 5-4 lower cutter work together to cut the outer sheath of the wire harness. The cutting action is later than the pressing action because the size of the 5-3 upper cutter is smaller than that of the 4-4 upper pressing block. And because the stroke of the 4-9 cutting cylinder is longer than that of the 4-1 clamping cylinder, it can cut off the cable insulation layer. When the 4-13 stripping cylinder moves, it drives the 5-6 lower slider to move through the 4-15 cylinder adapter, thereby moving the 3-2 core assembly. The keyway connection between the 4-15 cylinder adapter and the 5-6 lower slider is designed with a certain gap, allowing the 4-13 stripping cylinder to move idly in the initial stage, so as not to affect the completion of the wire clamping and cutting actions. After the wire clamping and cutting actions are completed, the 4-13 stripping cylinder can start to drive the 3-2 core assembly to move backward, pulling off the outer sheath of the wire harness. At this time, because the 1-7 air pipe is fixed at the 4-5 air pipe fixing block, the waste will be blown into the 1-5 waste discharge channel, and fall into the 1-6 waste collection box for storage. Next, release foot switch 1-4. The wire clamping cylinder 4-1 and the wire cutting cylinder 4-9 will reset in sequence, loosening the wire harness. At the same time, the wire stripping cylinder 4-13 is in an idle state. After the wire clamping cylinder 4-1 and the wire cutting cylinder 4-9 have reset, the wire stripping cylinder 4-13 will drive the mechanism assembly 3-2 to reset, thus completing the operation of the entire device.
