Description

Technical Field

[0001] This utility model relates to the field of wire processing equipment technology, and in particular to a pneumatic wire stripping machine for wire ends. Background Technology

[0002] In many manufacturing industries such as electronics, automotive wiring harnesses, and home appliances, wire stripping is an essential basic process. Pneumatic wire strippers have been widely used due to their fast stripping speed and powerful performance, and have become key equipment on automated production lines.

[0003] These pneumatic wire strippers typically use one or more pairs of blades to circumferentially cut and strip the outer sheath of wires. However, in actual production, there are many types of wires that need to be processed, with different wire diameters. In order to ensure the quality of wire stripping, it is necessary to completely cut off the outer insulation sheath without damaging the internal metal core. Operators must frequently change the blades of the appropriate specifications according to different wire diameters.

[0004] In many existing wire stripping machine designs, the blades are usually fastened with bolts or screws. This method of fixing requires operators to use special tools such as wrenches and screwdrivers to loosen the fasteners one by one, remove the old blades, replace them with new blades, and then tighten them one by one when changing the blades. The whole process is not only cumbersome and time-consuming, but also requires a certain level of skill from the operators. Especially in small-batch, multi-variety production tasks, frequent blade changing operations will lead to a lot of downtime for the equipment, which seriously restricts the overall production efficiency.

[0005] Therefore, this utility model proposes a pneumatic wire stripping machine for wire ends to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems of low production efficiency caused by the need for tools and cumbersome and time-consuming operation when changing the blades of existing pneumatic wire stripping machines for wire ends, this utility model aims to provide a pneumatic wire stripping machine for wire ends with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a pneumatic wire stripper for wire ends, including a worktable, a connecting plate, a mounting frame, a first pneumatic push rod, a second pneumatic push rod, a pad, and blade replacement mechanisms and wire limiting mechanisms on the left and right sides. The mounting frame and the connecting plate are fixedly connected to form a motion assembly, which is slidably mounted on the worktable. One end of the first pneumatic push rod is fixed to the worktable, and the other end is connected to the mounting frame to drive the assembly to reciprocate. The second pneumatic push rod is installed in the mounting frame and drives the right-side blade replacement mechanism to move.

[0008] Preferably, the wire restraint mechanism includes a hollow straight tube and a rubber ring. The rubber ring is disposed at the inlet end of the straight tube facing the arc blade. When the wire passes through, the rubber ring uses its elasticity to flexibly clamp the wire, while the straight tube constrains the wire to ensure that it enters the cutting area in a straight state, thereby improving the wire stripping accuracy.

[0009] Preferably, the pneumatic wire stripping machine for the wire ends also includes a collection trough, which is set on the workbench and located below the discharge port at the rear of the straight tube. This setting provides a concentrated drop area for the stripped insulation waste, effectively realizing the automatic collection of waste and avoiding pollution of the working environment.

[0010] Preferably, a pull ring is fixedly connected to the end of the baffle away from its pin. The pull ring provides a convenient point of leverage for the operator to operate with bare hands, making the insertion and locking and the pulling and unlocking of the baffle easier and less strenuous, greatly improving the ergonomic experience of operation.

[0011] Preferably, the overall height of the arc-shaped blade integrally formed with the slider is lower than the opening depth of the slot in the fixed seat. This structural design with a height difference provides sufficient and interference-free sliding space for the insertion and removal of the baffle, which is the key to ensuring that the locking operation can be carried out smoothly.

[0012] Preferably, the wire limiting mechanism is fixedly connected to the rear surface of the connecting plate by an independent fixing plate and several bolts. This detachable connection method not only ensures the stability and reliability of the installation, but also provides convenience for subsequent maintenance, replacement or fine-tuning of the wire limiting mechanism.

[0013] Preferably, the control systems of the first and second pneumatic push rods are configured to achieve a coordinated working sequence. First, the second pneumatic push rod drives the blades to merge and complete the circumferential cutting of the outer sheath. Then, the first pneumatic push rod drives the whole unit to move backward to complete the stripping action. This optimized two-step wire stripping process effectively avoids the problem of tearing or damaging the internal core wire due to pulling during the stripping process.

[0014] Preferably, the connecting plate is a generally flat substrate, and the mounting frame and the pad are both fixed to the left side of the connecting plate, with the pad located in front of the mounting frame. This compact integrated layout rationally plans and utilizes the installation space, making the structure of the entire device more concentrated and stable.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome and time-consuming blade replacement process in the prior art by setting up a blade replacement mechanism consisting of a fixed base, an arc-shaped blade with a slider, and a baffle with a pin. It utilizes the sliding cooperation between the slider and the T-slot and the locking of the pin and the slot to solve the problem of cumbersome and time-consuming blade replacement process in the prior art.

[0016] 2. This utility model solves the problems of inaccurate positioning, inconsistent stripping length, and easy damage to the core wire caused by wire bending in the prior art by setting a wire limiting mechanism composed of a straight tube and an elastic rubber ring behind the wire stripping blade, which straightens and elastically clamps the wire before stripping.

[0017] 3. This utility model, through the sequential coordination of the first pneumatic push rod and the second pneumatic push rod, achieves the action of the two arc-shaped blades first merging to cut off the outer skin, and then moving backward synchronously to peel it off. With the help of the collection groove set below, it solves the problems of easy tearing of the core wire and random scattering of waste materials that pollute the working environment in the prior art.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 5 This utility model provides a pneumatic wire stripper for wire ends, which aims to solve the problems of cumbersome blade replacement, difficulty in ensuring wire stripping accuracy, and easy scattering of waste in the prior art.

[0022] like Figure 1 and Figure 2 As shown, the pneumatic wire stripper for wire ends includes a worktable 1, a connecting plate 8, and a mounting frame 5 fixedly connected to the connecting plate 8. The assembly formed by the connecting plate 8 and the mounting frame 5 is slidably mounted on the worktable 1. One end of the first pneumatic push rod 4 is fixedly connected to the worktable 1, and the other end is movably connected to the mounting frame 5. The first pneumatic push rod 4 is used to drive the assembly of the connecting plate 8 and the mounting frame 5 to achieve reciprocating motion. A second pneumatic push rod 6 is installed inside the mounting frame 5. The wire stripper also includes a blade replacement mechanism 2 and a blade replacement mechanism 2 arranged opposite to each other on the left and right sides. The left blade replacement mechanism 2 is fixedly connected to the left side of the connecting plate 8 via a pad 9. The blade replacement mechanism 2 is connected to the output end of the second pneumatic push rod 6 and is driven by the second pneumatic push rod 6 to move relative to the left blade replacement mechanism 2.

[0023] like Figure 3 and Figure 5As shown, the blade changing mechanism 2, as the core cutting component, specifically includes a fixed base 201. The fixed base 201 has a T-slot 202, a slot 203, and a retaining groove 204 located inside the slot 203. The blade changing mechanism 2 also includes an arc-shaped blade 205, which is integrally formed with a slider 206. The cross-sectional shape of the slider 206 is adapted to the T-slot 202, allowing the slider 206 to slide within the T-slot 202. To lock the arc-shaped blade 205, the blade changing mechanism 2 further includes a baffle 207. The baffle 207 has... A pin 209 is provided, and a pull ring 208 is fixedly connected to the end of the baffle 207 away from the pin 209. When changing the blade, pulling the pull ring 208 will drive the baffle 207, so that the baffle 207 is inserted into the slot 203 and the pin 209 is engaged with the slot 204, thereby realizing the quick locking or unlocking of the arc blade 205. To ensure that the baffle 207 can be inserted smoothly, the overall height of the arc blade 205, which is integrally formed with the slider 206, is lower than the opening depth of the slot 203 in the fixing seat 201, so that the baffle 207 can slide over the slider 206.

[0024] like Figure 4 As shown, in order to ensure the wire stripping accuracy, the wire stripping machine is also equipped with a wire limiting mechanism 3. The wire limiting mechanism 3 is fixedly connected to the rear surface of the connecting plate 8 by a fixing plate 303 and several bolts 304. Its whole body is located directly behind the position where the left and right arc blades 205 are combined. The internal structure of the wire limiting mechanism 3 includes a hollow straight tube 301 and a rubber ring 302 set at the inlet end of the straight tube 301. The rubber ring 302 faces the arc blade 205 and is used to elastically clamp and initially straighten the wire passing through. The straight tube 301 is used to force the wire to keep straight.

[0025] like Figure 1 and Figure 2 As further shown, a collection trough 7 is also provided on the workbench 1. The collection trough 7 is located below the rear discharge port of the straight tube 301 away from the rubber ring 302. It is used to receive and collect the insulation sheath stripped from the wire. The connecting plate 8 is a base plate that is roughly flat. The mounting frame 5 and the pad 9 are both fixed on the left side of the connecting plate 8, and the pad 9 is located in front of the mounting frame 5.

[0026] Please refer to Figures 3 to 5The fixed base 201 of the blade changing mechanism 2 has a precisely formed T-shaped groove 202 for guiding and receiving, as well as a slot 203 and a locking slot 204 for locking. The fixed base 201 is fixedly connected to the pad 9 on the left side of the connecting plate 8 and the output end of the second pneumatic push rod 6. Its function is to provide a stable mounting reference and a quick replacement channel for the arc blade 205. The arc blade 205 has a slider 206 integrally formed with it. The shape of the slider 206 is adapted to the shape and size of the T-shaped groove 202. In the assembled state, the slider 206 of the arc blade 205 slides in the T-shaped groove 202 of the fixed base 201. This T-shaped track groove matching structure ensures the high stability and precise positioning of the arc blade 205 during the installation process.

[0027] Meanwhile, to prevent the arc blade 205 from coming off under force during wire stripping, the baffle 207 engages with the slot 204 of the fixing seat 201 via a pin 209. The body of the baffle 207 is inserted into the slot 203 and pressed against the slider 206. This locking structure of insertion and engagement ensures that the arc blade 205 is firmly locked in the fixing seat 201 during operation. The lock can be quickly released by pulling the pull ring 208, enabling convenient replacement of the blade.

[0028] In the setting of the wire limiting mechanism 3, it is fixed to the connecting plate 8 by the fixing plate 303 and the bolt 304, which ensures that it has a constant relative positional relationship with the blade changing mechanism 2. The rubber ring 302 and the straight tube 301 of the wire limiting mechanism 3 work together to ensure that the wire to be processed is always straight and effectively clamped when it is fed into the arc blade 205, thereby avoiding the problem of inaccurate cutting or damage to the core wire caused by the bending of the wire.

[0029] As a preferred embodiment, to make the wire positioning more accurate and effectively prevent bending, the structure of the wire limiting mechanism 3 is further optimized. Please refer to [reference needed]. Figure 4 It includes a hollow straight tube 301 and a rubber ring 302. The rubber ring 302 is fitted on the inlet end of the straight tube 301 facing the arc blade 205. When the wire passes through, the rubber ring 302 uses its elasticity to clamp the wire softly and firmly. The part that then enters the straight tube 301 is forced to remain straight. This combination structure ensures the stability of the wire's posture before it is cut.

[0030] As another preferred implementation method, for effective management of stripping waste, please refer to... Figure 1The wire stripping machine also includes a collection tank 7, which is set on the workbench 1. Its specific location is below the discharge port at the rear of the straight tube 301, away from the rubber ring 302. As the stripped wire sheath is pushed backward, it will fall directly into the collection tank 7 from the rear notch of the straight tube 301, thus preventing waste from flying outward.

[0031] As another preferred implementation, to improve the ergonomics of blade replacement operations, please refer to... Figure 3 The baffle 207 has a pull ring 208 fixedly connected to the end away from the pin 209. The operator can easily drive the baffle 207 to insert or pull out the slot 203 by pulling or pushing the pull ring 208, thereby quickly completing the locking or unlocking action of the arc blade 205.

[0032] As another preferred embodiment, to ensure smooth installation of the baffle 207 and avoid interference, please refer to... Figure 3 and Figure 5 The arc-shaped blade 205, which is integrally formed with the slider 206, is designed with a total height that is lower than the opening depth of the slot 203 in the fixing seat 201. This provides sufficient sliding space for the insertion of the baffle 207, ensuring that the baffle 207 can slide smoothly into the slot 203 and press firmly on top of the slider 206.

[0033] Working principle: Before stripping the wire, firstly, according to the wire size, insert the slider 206 with the corresponding arc blade 205 into the T-slot 202 of the fixing seat 201. Then, by pulling the pull ring 208, the baffle 207 is inserted into the slot 203, and the pin 209 on it engages with the slot 204, thereby firmly locking the arc blade 205. Through the sliding cooperation between the slider 206 and the T-slot 202 and the engagement and locking between the baffle 207 and the slot 204, the arc blade 205 is quickly installed and fixed, solving the problem of cumbersome and time-consuming blade replacement in the prior art. After the preparation is complete, the wire end is passed through the rubber ring 302 of the wire limiting mechanism 3 and extended into the straight tube 301. The straight tube 301 is fixed on the fixing plate 303 and threadedly connected to the workbench 1 by the bolt 304. The elastic clamping of the rubber ring 302 and the constraint of the tube wall of the straight tube 301 together ensure that the wire is in a straight and stable state before stripping. After the equipment is started, the second pneumatic pusher 6 moves first, its output end extends, and pushes the blade changing mechanism 2 on the right side to move to the left until the arc blades 205 on the left and right sides merge, accurately cutting the outer insulation of the wire without damaging the inner core wire. Immediately afterwards, the first pneumatic pusher 4 begins to retract, driving the mounting frame 5 connected to it and the connecting plate 8 fixed on the mounting frame 5 to slide backward as a whole. Meanwhile, the blade changing mechanism 2 on the other side is connected to the pad 9 on the connecting plate 8. Therefore, the arc blades 205 on both sides will move backward synchronously as a whole, completely peeling off the cut wire insulation from the wire end. The peeled waste insulation falls from the rear discharge port of the straight tube 301 into the collection trough 7 below during the backward movement. Through the timing of the first pneumatic pusher 4 and the second pneumatic pusher 6, and with the help of the wire limiting mechanism 3 to straighten, this utility model solves the problem of wire stripping error and core wire damage caused by inaccurate wire bending and positioning, and realizes automatic collection of waste, avoiding environmental pollution.
