Description

Technical Field

[0001] This utility model relates to the technical field of carbon brush processing equipment, and in particular to a copper wire cutting device used in carbon brush copper wire embedding equipment. Background Technology

[0002] To improve the safety and durability of critical automotive components, modern automotive fuel pump motors commonly employ carbon brush structures. During carbon brush manufacturing, copper wire must be embedded into the brush body. This process places high demands on the length of the copper wire, the embedding depth, and the cutting quality. Currently, the copper wire is typically released continuously from a spool and then cut to a predetermined length after embedding. If the cutting process is not precisely controlled, it can easily lead to inconsistent copper wire lengths and uneven cuts, thus affecting the quality of subsequent welding processes and the stability of the embedding depth. Ultimately, this negatively impacts the product's conductivity and mechanical strength.

[0003] In existing technologies, the feeding and cutting of copper wire largely rely on manual intervention or mechanical limits, which suffers from drawbacks such as low control precision, slow response speed, and cumbersome adjustments, making it difficult to meet the demands of high-efficiency and high-consistency production. Therefore, there is an urgent need for a copper wire cutting device that can achieve precise control of the feeding amount, stable and reliable cutting action, and has an automated feedback adjustment function, in order to improve the overall quality and production efficiency of carbon brush products. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a copper wire cutting device for copper wire embedding equipment, which solves the problems of unstable copper wire cutting quality, cumbersome equipment adjustment, low control precision, and low efficiency in the prior art.

[0005] The specific technical solution is as follows:

[0006] A copper wire cutting device for copper wire embedding equipment includes a base plate, a drive cylinder, a sliding plate, a cutting cylinder, and blades. A first linear guide rail is provided at the bottom of the base plate. The sliding plate is movably mounted on the first linear guide rail via a slider. One end of the sliding plate is driven to move by a drive cylinder located at one end of the base plate. A fixed plate is mounted on the bottom of the sliding plate via a connecting seat. A second linear guide rail is provided on the fixed plate. A moving component is movably mounted on the second linear guide rail via a slider. The rear end of the moving component is driven to move by a cutting cylinder located on the connecting seat. Two linkage blocks are hinged to the front ends of the moving component on both sides. A blade is hinged to the front end of each of the two linkage blocks. The two blades are distributed left and right, and their middle parts are hinged together by a pin and movably mounted on the fixed plate. The front ends of the two blades extend beyond the fixed plate and have cutting edges. The cutting cylinder pushes the moving component to move back and forth, causing the moving component to drive the blades along the pin via the two linkage blocks, opening and closing the cutting edges of the two blades to cut the copper wire.

[0007] Furthermore, the front end base plate of the moving part is provided with a forward-extending connecting block, and the linkage block is horizontally hinged on both sides of the connecting block by a pin.

[0008] Furthermore, the two linkage blocks are arranged symmetrically in a figure-eight shape.

[0009] Furthermore, each blade has a vertically mounted pivot at its rear end, which extends longitudinally through the front end of the linkage block and is rotatably connected to it.

[0010] Furthermore, a mounting plate is vertically provided at one end of the base plate, and the drive cylinder is horizontally mounted on the mounting plate.

[0011] Furthermore, the bottom of the connecting seat is provided with a notch for accommodating the piston rod end of the shearing cylinder.

[0012] The beneficial effects of this utility model are reflected in:

[0013] (1) High product quality: After the copper wire is embedded, the drive cylinder drives and pushes the blade to the position of the copper wire. Then the shearing cylinder pushes the moving parts to realize the opening and closing movement of the blade, which satisfies the precise shearing of the copper wire. After the copper wire is sheared, the remaining length can be effectively controlled, which can improve the strength of the copper wire embedding, thereby ensuring the conductivity reliability and mechanical performance of the carbon brush product.

[0014] (2) Easy to operate and efficient: The cutting device of this utility model has a simple structure, is easy to manufacture and install, and can be widely used in various copper wire cutting scenarios. Its standardized automatic control method significantly reduces equipment adjustment time and dependence on manpower, and improves production efficiency. Attached Figure Description

[0020] Please see the appendix Figure 1-2 This embodiment provides a copper wire cutting device for copper wire embedding equipment, including a base plate 1, a drive cylinder 2, a sliding plate 4, a cutting cylinder 9, and a blade 11. A mounting plate 21 is vertically mounted at one end of the base plate 1, and the drive cylinder 2 is horizontally mounted on the mounting plate 21. A first linear guide rail 3 is provided along the length of the bottom of the base plate 1. The sliding plate 4 is horizontally slidably mounted on the first linear guide rail 3 via a slider. One end of the sliding plate 4 is driven to move by the drive cylinder 2 located at one end of the base plate 1. A fixed plate 6 is horizontally mounted on the bottom of the sliding plate 4 via a longitudinally arranged connecting seat 5. A second linear guide rail 7 is provided on the fixed plate 6. A moving part 8, which is a rectangular block, is movably mounted on the second linear guide rail 7 via a slider. The rear end of the moving part 8 is driven to move by the cutting cylinder 9 located on the connecting seat 5. Two linkage blocks are hinged to the front ends of the moving part 8. Two blades 11 are hinged to the front end of the device, and the two blades 11 are distributed on the left and right. The middle parts of the two blades 11 overlap and are connected by a pin 111. The bottom end of the pin 111 is fixed to the fixed plate 6, so that the two blades 11 can be movably set on the fixed plate 6 along the pin 111. The front ends of the two blades 11 extend outside the fixed plate 6 and are provided with cutting edges 113. The moving part 8 is pushed back and forth by the shearing cylinder 9, so that the moving part 8 drives the blades 11 to move along the pin 111 through two linkage blocks, and causes the cutting edges 113 at the front ends of the two blades 11 to open and close, so as to cut the copper wire.

[0021] In this embodiment, the front end base plate 1 of the moving component 8 is provided with a forward-extending connecting block 81. Linkage blocks are horizontally hinged to both sides of the connecting block 81 via pins 82. The two linkage blocks are arranged symmetrically in a figure-eight shape. A rotating shaft 112 is vertically provided at the rear end of each blade 11. The rotating shaft 112 longitudinally passes through the front end of the linkage block and is rotatably connected to it. This causes the two linkage blocks to push the rotating shaft 112 to both sides along the pin 82, thereby causing the rear ends of the two blades 11 to separate outwards. Simultaneously, the cutting edge 113 at the front end of the blade 11 closes and smoothly cuts the embedded copper wire tail end.

[0022] In this embodiment, the shearing cylinder 9 is horizontally fixed to the connecting seat 5 by the cylinder frame. The bottom of the connecting seat 5 is provided with a notch 51, so that the piston rod end of the shearing cylinder 9 passes through the notch 51 and is connected and fixed to the rear end of the moving part 8.

[0023] When embedding copper wire in the carbon brush, the wire feeding device uses a motor to drive the drive shaft to rotate, which in turn drives the wire reel to rotate and feed the wire in a set direction. After the copper wire is released, it passes through a guide wheel, then through upper and lower swing wheels, and enters the copper wire embedding device. Simultaneously, as the swing wheels rotate up and down, a sensor outputs a switching signal through a sensing element, controlling the start and stop of the motor. This controls both the amount of copper wire released and the amount of copper wire embedded during embedding.

[0024] The working principle of this utility model is as follows: After the copper wire is embedded in the carbon brush, the drive cylinder 2 drives the sliding plate 4 to move forward, pushing the blade 11 to the designated cutting position of the copper wire. At the same time, the cutting edge 113 of the blade 11 unfolds and aligns with the copper wire. Then, the shearing cylinder 9 pushes the moving part 8, so that the moving part 8 drives the blade 11 to close through the linkage block, thereby satisfying the shearing of the copper wire.

[0025] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
