A wire cutting mechanism

Abstract

This utility model discloses a wire cutting mechanism, including a feeding machine and a cutting device. The feeding machine holds a wire, which is then cut by the cutting device. The mechanism includes: a mounting frame mounted on the feeding machine; a power arm mounted on the mounting frame with a reversing wheel; and a pneumatic pump connected to the power arm. The pneumatic pump drives the power arm, and a rotating base at the bottom of the pneumatic pump is connected to the mounting frame. The rotating base contains a mounting shaft, and the pneumatic pump is mounted on the mounting shaft. This wire cutting mechanism, through the linkage between the pneumatic pump and the power arm, allows the power arm to rotate around the connecting shaft when the pneumatic pump drives the telescopic rod to extend or retract. Simultaneously, a slider slides on the guide rail, changing the position of the reversing wheel. This achieves precise adjustment of the tension during wire transport, solving the problem of uneven cuts caused by the inability to adjust tension in traditional devices.

Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, specifically a wire cutting mechanism. Background Technology

[0002] Automatic wire cutting devices are widely used in fields such as electronic equipment manufacturing and power system installation because they can efficiently complete fixed-length wire cutting operations. They achieve automated wire processing through the cooperation of a conveying mechanism and a cutting mechanism. However, traditional wire cutting devices generally lack an effective adjustment mechanism for the tension of the wire during transportation. When the wire becomes slack during transportation, its tension cannot be adjusted in time. This causes the wire to easily shift its position when entering the cutting station, resulting in uneven force and shaking during the cutting process. Ultimately, this leads to problems such as uneven cuts and poor cross-sectional quality, seriously affecting the accuracy of wire cutting and the quality stability of subsequent processing. It also limits the application of automatic wire cutting devices in high-precision processing scenarios to some extent. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting mechanism, comprising a feeding machine and a cutting device, wherein a wire is disposed in the feeding machine, and the wire is cut by the cutting device, comprising:

[0005] Mounting bracket, which is mounted on the discharge machine;

[0006] A power arm, which is mounted on the mounting frame and has a directional wheel;

[0007] A pneumatic pump is connected to the power arm, and the pneumatic pump is used to drive the power arm.

[0008] Preferably, the bottom of the pneumatic pump is provided with a rotating seat, the rotating seat is connected to the mounting bracket, the rotating seat is provided with a mounting shaft, and the pneumatic pump is mounted on the mounting shaft.

[0009] Preferably, the pneumatic pump is equipped with a telescopic rod, one end of which is connected to a connector, and the connector is equipped with an adapter shaft, which is connected to the power arm.

[0010] Preferably, the mounting frame is provided with a guiding mechanism, the guiding mechanism including a support platform provided on the mounting frame, a support plate provided on the support platform, at least one support frame provided on the support plate, and a guide wheel provided on the support frame.

[0011] Preferably, the mounting bracket is further provided with a guide rail, which is connected to the power arm and supports the power arm.

[0012] Preferably, a connecting shaft is provided at the connection between the power arm and the mounting bracket.

[0013] Preferably, the mounting bracket is further provided with a guide wheel, which is used to guide the wire into the cutting device.

[0014] Preferably, the discharge machine is equipped with a discharge wheel, and the cutting device is equipped with a feed inlet.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This wire cutting mechanism, through the linkage structure of the pneumatic pump and the power arm, when the pneumatic pump drives the telescopic rod to extend and retract, it pushes the power arm to rotate around the connecting shaft. At the same time, the slider slides on the guide rail, changing the position of the reversing wheel, thus achieving precise adjustment of the tension during wire transportation. This solves the problem of uneven cuts caused by the inability to adjust tension in traditional devices. The setting of the support platform, support plate, and guide wheel in the guiding mechanism forms a stable wire transmission path, ensuring that the wire smoothly transitions from the discharge wheel to the reversing wheel, reducing deviation during transmission. The coaxial design of the discharge wheel and the feed inlet of the cutting device, combined with the adjustable spacing of the roller clamping at the feed inlet, ensures that the wire accurately enters the cutting station, further improving cutting accuracy. The support of the guide rail for the power arm, combined with the design of the rotating seat, ensures that the pneumatic pump maintains a consistent thrust direction when pushing the power arm, enhancing the stability of the device operation. The power arm and the mounting frame are connected by a connecting shaft, combined with an adjustable slide rail structure, making the reversing wheel move more flexibly when adjusting tension, adapting to the processing needs of wires of different specifications, and expanding the application scenarios of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a wire cutting mechanism, including a feeding machine 1 and a cutting device 9. A wire 2 is placed in the feeding machine 1, and the wire 2 is cut by the cutting device 9. The feeding machine 1 is equipped with a feeding wheel 11, through which the wire 2 is discharged and moved to a mounting frame 3 by the traction of the feeding wheel 11. The cutting device 9 is equipped with a feeding port 91, and the feeding port 91 is equipped with two adjustable rollers for clamping the wire 2 and conveying it into the cutting device 9.

[0023] Mounting frame 3 is mounted on the discharge machine 1 and supports the remaining structure. Mounting frame 3 is equipped with a guide mechanism 4, which receives the wire 2 transmitted from the discharge wheel 11 and guides it to the deflector wheel 7. The guide mechanism 4 includes a support platform 44 mounted on the mounting frame 3, which stably supports the guide mechanism 4. A support plate 41 is mounted on the support platform 44 and connected to a support frame 42. At least one support frame 42 is mounted on the support plate 41, which is rotatably connected to a guide wheel 43. A rotating shaft is mounted on the support frame 42, and the guide wheel 43 is sleeved on the rotating shaft. The guide wheel 43 receives the wire 2. Mounting frame 3 also has a guide wheel 8, which receives the wire 2 transmitted from the deflector wheel 7 and then conveys it to the cutting device 9. The guide wheel 8 guides the wire 2 into the cutting device 9.

[0024] The power arm 32, which is connected to the connecting shaft 321, is mounted on the mounting frame 3 and has a directional wheel 7. The directional wheel 7 guides the wire 2 and controls the overall tension of the wire 2. The mounting frame 3 also has a guide rail 31, which supports the power arm 32. An adjustable slide rail is provided between the guide rail 31 and the power arm 32. This design allows the guide rail 31 to still support the power arm 32 when it rotates. The guide rail 31 is connected to the power arm 32 and supports the power arm 32. The connecting shaft 321 is provided at the connection between the power arm 32 and the mounting frame 3, and the connecting shaft 321 allows the power arm 32 to rotate.

[0025] A pneumatic pump 6 is connected to a power arm 32. The pneumatic pump 6 is used to adjust the position of the power arm 32 and to push the power arm 32. A rotating seat 5 is located at the bottom of the pneumatic pump 6, which is used to fix the pneumatic pump 6 to the mounting bracket 3. The rotating seat 5 is connected to the mounting bracket 3 and contains a mounting shaft that allows the pneumatic pump 6 to rotate. Thus, when the pneumatic pump 6 drives the telescopic rod 61 to push the power arm 32, the body of the pneumatic pump 6 also... It will rotate slightly along with it. The air pump 6 is installed on the mounting shaft. The air pump 6 is equipped with a telescopic rod 61. The air pump 6 is used to control the extension and retraction of the telescopic rod 61. One end of the telescopic rod 61 is connected to a connector 62. The connector 62 is used to connect with the power arm 32 through an adapter shaft 63. The adapter shaft 63 is provided on the connector 62. The adapter shaft 63 is used to adjust the connection between the power arm 32 and the connector 62. The adapter shaft 63 is connected to the power arm 32.

[0026] When the wire cutting mechanism is in use, the feeder 1 pulls the wire 2 out through the feed wheel 11. The wire 2 is transmitted through the guide mechanism 4 on the mounting frame 3. The guide wheel 43 receives the wire 2 and guides it to the deflector wheel 7. The deflector wheel 7 is mounted on the power arm 32. The power arm 32 is connected to the mounting frame 3 through the connecting shaft 321 and can rotate. At the same time, its bottom is slidably connected to the slide rail of the guide rail 31 through the slider. The guide rail 31 is a T-shaped slide rail fixed in the vertical direction to support the power arm 32. The air pump 6 is fixed on the mounting frame 3 through the rotating seat 5. The extension and retraction of its internal telescopic rod 61 is driven by air pressure. The wire 2 is guided into the feed port 91 of the cutting device 9 through the guide wheel 8. The upper and lower rotating rollers of the feed port 91 adjust the spacing to clamp the wire 2 and convey it into the cutting device 9 for cutting.

[0027] When the wire 2 needs to be cut, the air pump 6 rotates slightly around the mounting shaft of the rotating seat 5 to keep the thrust direction consistent with the force direction of the power arm 32, thereby pushing the power arm 32 to rotate around the connecting shaft 321. At the same time, the slider slides up and down on the guide rail 31, causing the position of the deflector wheel 7 to move downward, extending the guiding length of the wire 2, thereby making the wire 2 in the cutting device 9 taut, and thus achieving a better cutting effect.

[0028] After the cutting device 9 completes the cutting of the wire 2, the air pump 6 retracts the telescopic rod 61, allowing the power arm 32 to return to its previous position.
