A device for cutting waste wires from a network transformer

Abstract

This utility model discloses a waste wire cutting device for network transformers, aiming to solve the problems of inaccurate fixed blade reset and easy displacement of moving blades leading to misalignment of wire slots in existing wire cutting devices. The device includes a fixed base, fixed blades, moving blades, and a linear drive element. The fixed base has a cavity to accommodate the network transformer; two fixed blades are respectively located on the left and right sides of the fixed base and have first wire slots, while two moving blades are correspondingly located outside the fixed blades and have second wire slots. The fixed blades are positioned between the moving blades and the fixed base. A push seat that moves back and forth on the fixed base is connected to the linear drive element and abuts against the moving blades. The connecting post of the moving blade is inserted into the front and rear guide slot of the fixed base, and tension springs on both sides of the push seat connect to the connecting post. The linear drive element drives the push seat to move the moving blades back and forth. The guide slots constrain the trajectory of the moving blades, and the tension springs assist in the reset of the moving blades, ensuring precise alignment of the wire slots between the moving blades and fixed blades after reset, achieving stable wire cutting, improving cutting accuracy and efficiency, and is suitable for large-scale production of network transformers.

Description

Technical Field

[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a device for cutting waste wires in a network transformer. Background Technology

[0002] Network transformers are core components of communication equipment. In their production process, after the magnetic winding is coiled to form a coil and the coil is installed in the casing, excess waste wire needs to be cut off to ensure product performance. Currently, the industry mainstream adopts a cylinder-driven wire-cutting structure, which uses the extension and retraction of the cylinder to move the moving blade relative to the fixed blade to cut off the waste wire. Although the structure is simple, it is difficult to meet the requirements of high-precision production.

[0003] The existing solution has two major problems: First, the feed and reset of the fixed blade both rely on the same cylinder for driving, which is prone to accidental movement and inaccurate reset due to fluctuations in air source pressure and wear of components; Second, the structural design of the direct connection between the cylinder and the moving blade has obvious play, which causes the actual position of the moving blade to deviate and cannot stably maintain the preset shearing trajectory.

[0004] The wire slots of the fixed blade and the moving blade need to be precisely aligned for the wire to be cut to enter smoothly. If they are not aligned, the wire will not be able to enter the slots, and thus cutting will not be possible. When the fixed blade is not reset accurately or the moving blade is misaligned, it is very easy for the wire slots of the fixed blade and the moving blade to become misaligned. This not only causes problems such as missed cuts, incomplete cuts, and incorrect lead lengths, but also increases labor costs, reduces production efficiency, and may even damage the coil, affecting the electrical performance of the network transformer and hindering high-quality production. Therefore, there is an urgent need for a new type of waste wire cutting device to solve the above-mentioned precision problems. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a device for cutting waste wires from a network transformer.

[0006] A network transformer waste wire cutting device designed for this purpose includes a fixed base, a fixed blade, a moving blade, and a linear drive element;

[0007] The mounting base is provided with a cavity for accommodating the network transformer;

[0008] Two fixed blades are provided and are respectively located on the left and right sides of the fixed base; the fixed blades are arranged with a number of first grooves along the front-back direction.

[0009] Two moving blades are provided and are respectively located on the left and right sides of the fixed base; the moving blades are arranged in a plurality of second grooves along the front-back direction; the fixed blade is located between the moving blades and the fixed base;

[0010] A push seat connected to the linear drive element is movably mounted on the fixed base, and the push seat abuts against the moving blade;

[0011] The moving blade is provided with a connecting post, and tension springs are connected to the left and right sides of the push seat. The end of the tension spring away from the push seat is connected to the connecting post. The fixed seat is provided with a guide groove extending in the front-back direction, and the connecting post is at least partially inserted into the guide groove.

[0012] The linear drive element is used to drive the push seat to move back and forth relative to the fixed seat.

[0013] Preferably, the fixed base is fixedly connected to the mounting base, and the linear drive element is fixedly mounted on the mounting base.

[0014] Preferably, guide seats are provided on the left and right sides of the fixed base, and the guide groove is provided on the guide seats.

[0015] Preferably, the guide seat is fixedly connected to the moving blade, and a through-space is provided between the two, with the moving blade movably disposed within the through-space.

[0016] Preferably, the linear drive element is a cylinder.

[0017] Compared with the prior art, this invention effectively solves the problem of wire groove alignment in existing wire cutting methods through core structural optimization. Specific advantages are as follows:

[0018] The connecting post of the moving blade engages with the guide groove of the fixed base, strictly constraining the moving blade to move only in the forward and backward direction, preventing lateral deviation. Simultaneously, a tension spring connects the push base and the connecting post of the moving blade, providing a stable backward reset force for the moving blade. With the combined effect of these two mechanisms, the moving blade can precisely stop at the preset position after reset, ensuring complete alignment between the moving blade groove and the fixed blade groove. This guarantees smooth entry of the wire to be cut into the groove, completely solving the cutting failure problem caused by inaccurate reset in existing solutions and significantly improving wire cutting accuracy.

[0030] See Figures 1-3 A device for cutting waste wires from a network transformer is characterized by comprising a fixed base 10, fixed blades 20, movable blades 30, and a linear drive element 40; the fixed base 10 is provided with a cavity for accommodating a network transformer 100; two fixed blades 20 are provided and are respectively disposed on the left and right sides of the fixed base 10; the fixed blades 20 are arranged with a plurality of first wire grooves 200 along the front-back direction; two movable blades 30 are provided and are respectively disposed on the left and right sides of the fixed base 10; the movable blades 30 are arranged with a plurality of second wire grooves 300 along the front-back direction; the fixed blades 20 are disposed between the movable blades 30 and the fixed base. Between 10; a push seat 70 connected to the linear drive element 40 is movably disposed on the fixed base 10, and the push seat 70 abuts against the moving blade 30; the moving blade 30 is provided with a connecting post 310, and tension springs 60 are connected to the left and right sides of the push seat 70, with one end of the tension spring 60 away from the push seat 70 connected to the connecting post 310; the fixed base 10 is provided with a guide groove 510 extending in the front-back direction, and the connecting post 310 is at least partially inserted into the guide groove 510; the linear drive element 40 is used to drive the push seat 70 to move back and forth relative to the fixed base 10.

[0031] This network transformer waste wire cutting device achieves precise positioning and cutting of the wire to be cut through the coordinated movement of linear drive elements, push base, moving blade, fixed blade, and auxiliary structures. The specific workflow is as follows:

[0032] Initial standby state: When the device is not started, the linear drive element is in the retracted state, and the push seat is held in the initial position behind the fixed seat under the traction of the linear drive element; the tension spring is in the naturally taut state, and the moving blade is pulled backward through the connecting column, so that the moving blade is also held in the rear reset position. At this time, the second groove of the moving blade is precisely aligned with the first groove of the fixed blade, and the two maintain a preset initial gap, waiting for the network transformer to enter the cavity.

[0033] Workpiece positioning: The network transformer, after being installed in the housing, is fixed in the cavity of the fixed base. The wire to be cut, extending from the network transformer coil, naturally extends to the first groove of the fixed blade and the second groove of the moving blade (at this time, the two grooves are aligned), thus completing the precise positioning of the workpiece.

[0034] Drive feed and shearing preparation: Start the linear drive element, and the linear drive element outputs driving force to move the push seat forward along the fixed seat; since the push seat and the moving blade are in contact, the push seat pushes the moving blade forward in sync during the forward movement.

[0035] Cutting action execution: As the pusher continues to push the moving blade forward, the moving blade moves forward relative to the fixed blade. During this process, the first groove of the fixed blade and the second groove of the moving blade, which were originally precisely aligned, gradually become misaligned. The wire to be cut, placed in the two grooves, is clamped by the misaligned groove walls. The moving blade continues to move forward relative to the fixed blade, using the shearing force generated by the misalignment of the two grooves to precisely cut the wire to be cut in the groove, completing the waste wire cutting action.

[0036] Reset and Standby: After shearing is completed, the linear drive element stops outputting driving force and begins to retract, driving the pusher seat to move backward along the fixed seat, releasing the forward thrust on the moving blade; at this time, the tension spring plays a role, pulling the moving blade to move backward synchronously along the guide groove through the connecting column, ensuring that the moving blade is stably reset with the pusher seat; until the pusher seat returns to the rear initial position, the moving blade also returns to the initial reset position synchronously, the second groove of the moving blade and the first groove of the fixed blade are precisely aligned again, and the device returns to the initial standby state, waiting for the next waste wire shearing operation of the network transformer.

[0037] See Figures 1 to 3 The fixed base 10 is fixedly connected to the mounting base 400, and the linear drive element 40 is fixedly disposed on the mounting base 400.

[0038] See Figure 1 and Figure 2 The fixed base 10 has guide seats 50 on its left and right sides, and guide grooves 510 are disposed on the guide seats 50. The guide seats on the left and right sides of the fixed base are key support structures for the stable movement of the moving tool. The guide grooves opened on the guide seats provide a precise movement track for the moving tool connecting column.

[0039] See Figure 1The guide seat 50 is fixedly connected to the moving blade 30, and a through-space 80 is provided between them. The moving blade 30 is movably disposed within the through-space 80. The fixed connection between the guide seat and the moving blade, forming a through-space, provides a dedicated movement channel for the moving blade. The moving blade can move stably back and forth within this space, preventing blade deviation and ensuring accurate movement trajectory, providing reliable support for alignment and shearing of the moving blade with the fixed blade groove.

[0040] In this invention, the linear drive element 40 is a cylinder.
